The field in question is that of the installation of lifting equipment; specifically, it concerns a device known as<a style='color:#0000CC;font-size:16px' href='\/en\/1772\/' title='overhead travelling crane' target='_blank'>overhead travelling crane<\/a>Quick-fit devices for sliding contact lines, along with the corresponding installation methods.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>Background technology:<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>2. There is a type of gantry crane known as a bridge crane, or sometimes referred to as an overhead crane, whose gantry runs on elevated rails.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>3. Safe conductor rails are one of the essential requirements for the proper operation of overhead cranes. Overhead cranes in the main powerhouse of a hydroelectric station are fitted with conductor rails, which are typically installed at a height of 10 metres above the ground.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>At a height of 40 metres, with no access platforms in the vicinity, the conventional method typically involves setting up a Z-shaped mobile installation platform on the track, each movement of the installation platform allows only one conductor rail bracket to be positioned, whilst the positioning of the next conductor rail bracket must be carried out anew. This not only increases the workload but also reduces installation efficiency, Positioning each conductor rail bracket individually tends to lead to an increase in cumulative horizontal errors, which in turn affects the horizontal alignment of the brackets. This may also reduce the service life of the bridge crane\u2019s collector or cause the collector to derail whilst the crane is in operation.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>Technology Enabling Elements:<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>4. The technical problem addressed by the present invention is that, with each movement of the installation platform, only one conductor rail bracket can be positioned. The objective is to provide a device for the rapid installation of conductor rails on a bridge crane, together with a set of installation methods; this method resolves issues relating to work efficiency, such as the relatively low efficiency of conductor rail installation.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>5. The present invention is characterised by the following:<a style='color:#0000CC;font-size:16px' href='\/en\/1450\/' title='Technical programme' target='_blank'>Technical programme<\/a>Implementation:<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>6.

A device for the installation and commissioning of the conductor rail, mounted on the bridge crane\u2019s conductor rail guard;<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>8. The structure that forms the conductor rail bracket is secured to the pre-embedded base plate of the rock-anchored girder; at the same time, the conductor rail is fitted into the conductor rail clamps provided on that bracket.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>9. The slip ring installation and commissioning device referred to comprises:<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>10. Vertical panels;<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>11. There is a fixing component that securely connects the vertical panel to the bridge crane conductor rail guard, holding it firmly in place.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>12. The conductor rail has a height-adjustment crossbar, which is fixed perpendicular to the vertical panel. This height-adjustment crossbar is positioned horizontally and is located beneath the conductor rail bracket!<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>13. During the installation of the conductor rail, a positioning tool known as the conductor rail positioning ruler is used to determine its position; this is connected to another component, the conductor rail elevation positioning crossbar, and the way in which the conductor rail positioning ruler fits against the conductor rail mounting clamp is specifically designed.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>14. Specifically, a long through-hole extending vertically is provided on the aforementioned vertical panel; the specific fixing assembly comprises the following components: <\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>15. a U-shaped clamp, which is fixedly connected to the protective frame for the bridge crane\u2019s conductor rail;<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>16. The horizontal levelling screw connects the U-shaped clamp to the vertical panel; one end is fixed to the U-shaped clamp, whilst the other end passes through a long through-hole and is secured to a matching nut.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>17. In this case, the horizontal elevation adjustment screw can slide up and down along the through-hole.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>18. In the scenario where the best of the best is selected and there are multiple through-holes, the number of mounting components corresponds to the number of through-holes.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>etc.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>19. Furthermore, there are several conductor rail brackets, and these brackets, from top to bottom, are each securely fixed to the pre-embedded foundation plate of the rock-anchored girder; furthermore, it can be seen that the distance between any two adjacent conductor rail brackets is the same, i.e. they are all equal.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>20. The number of sliding contact line elevation positioning cross-bars is the same as the number of sliding contact line brackets, and there are multiple such cross-bars; all of which are connected to the vertical panels via downward-facing fixing brackets; furthermore, the distance between any two adjacent conductor rail elevation positioning crossbars is equal.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>21. The busbar brackets and the busbar elevation positioning crossbars are arranged at regular intervals.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>22. Specifically, the positioning ruler for the sliding contact rail is connected to the horizontal bar for positioning the elevation of the sliding contact rail in a sliding manner by means of a locking screw.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>23. Furthermore, a fixed-height positioning block is provided between the sliding contact line elevation positioning crossbar and the sliding contact line bracket; the lower end of the fixed-height positioning block is securely connected to the sliding contact line elevation positioning crossbar, whilst the upper end of the fixed-height positioning block rests against the sliding contact line bracket.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>24. In another embodiment, there is a situation where a quick-installation device for bridge crane conductor rails is provided; this device further comprises: <\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>25. The conductor rail mounting platform is mounted on the aforementioned bridge crane conductor rail protective frame, whilst the conductor rail installation and commissioning device is situated between the conductor rail mounting platform and the pre-embedded foundation plate of the rock-anchored girder.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>26. The sliding contact rail mounting platform referred to comprises:<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>27.

A hook, connected to the protective frame for the bridge crane\u2019s conductor rail;<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>29. The vertical rod, which connects the hook and the horizontal platform.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>30. Specifically, the width of the said sliding contact line mounting platform is less than the distance between the said bridge crane sliding contact line protective frame and the embedded foundation plate of the rock-anchored girder.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>31. In a preferred embodiment, safety railings are provided on both sides of the horizontal platform, and ladders are provided for ascending and descending the rock anchor beams.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>32. A method for installing conductor rails on bridge cranes; this method is based on the aforementioned quick-installation device for conductor rails on bridge cranes and comprises the following steps: <\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>33. Construct the sliding contact line mounting platform, as well as the sliding contact line installation and commissioning fixture, and the sliding contact line brackets.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>34.s2: Carry out the operation of hoisting the conductor rail mounting platform into position, then connect the mounting platform to the bridge crane\u2019s conductor rail guard.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>35.s3. Install the sliding contact line mounting and adjustment device using the sliding contact line mounting platform;<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>36. Based on the position of the conductor rail bracket to be installed, adjust the position of the elevation positioning crossbar for the conductor rail in the vertical direction, whilst ensuring that it remains level.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>37. Using the conductor rail that requires installation, adjust the position of the conductor rail positioning gauge horizontally in relation to the position of the conductor rail bracket.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>38. Above the elevation reference bar of the S6 conductor rail, fixed-height positioning blocks are installed to determine the position of the conductor rail brackets; with these positioning blocks in place, the reference points remain unchanged.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>39. First, position the conductor rail bracket horizontally on the positioning block at the specified height; then, weld the conductor rail bracket to the base plate embedded in the rock-anchor beam.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>40.s8. Install the conductor rail clamps in accordance with the position of the positioning gauge relative to the conductor rail;<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>41. As the gantry crane moves along the tracks, the protective frame for its conductor rail is also moved to the installation position of the next conductor rail bracket, thus completing the entire movement process.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>42. Repeat steps s9, s8 and s7 until all the conductor rail brackets have been fitted. Continue in this manner until the installation is complete.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>43. Reset the bridge crane to its original position, then install the conductor rails onto the conductor rail brackets one by one in sequence.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>44.

To make the objectives of the present invention clear and unambiguous, and to ensure that the technical solution is precise and unambiguous and its advantages are clearly highlighted, a further detailed explanation of the invention will now be provided with reference to the accompanying drawings and embodiments, so that it may be understood. The specific embodiments described herein are intended solely to illustrate the relevant content and are not intended to limit the scope of the invention.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>51. Furthermore, it should be noted that, for the sake of clarity, the accompanying drawings show only those parts relevant to the present invention.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>52. Where there is no conflict, the various modes of practice of the present invention and the features present in the embodiments may be combined with one another. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>53. Example 1<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>54. The present embodiment addresses a problem already recognised in the prior art. As described below, each time the mounting platform is moved, only one sliding contact rail bracket 3 can be positioned; subsequently, to position the next sliding contact rail, the positioning operation must be carried out again. This process not only increases the workload but also reduces installation efficiency. Furthermore, when each sliding contact rail bracket 3 is positioned individually, it is highly likely that cumulative horizontal errors in the brackets will increase, which in turn affects the horizontal alignment of the conductor rail brackets 3. Consequently, this may shorten the service life of the bridge crane 1\u2019s collector and could even lead to the collector derailing whilst the bridge crane 1 is in operation.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>55. There is a device designed for the rapid installation of conductor rails on bridge cranes; this device comprises equipment for the installation and commissioning of the conductor rails, as well as conductor rail brackets 3.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>56. The sliding contact line installation and commissioning device, mounted on the bridge crane\u2019s sliding contact line protective frame 8;<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>57. The bridge crane conductor rail protection frame No. 8 is currently the only such piece of equipment in the possession of Bridge Crane No. 1; its primary purpose is to protect the conductor rail; it is designed to prevent Bridge Crane No. 1 from coming into contact with the conductor rail whilst in operation, thereby preventing damage to the conductor rail.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>58. The sliding contact line installation and commissioning device can be connected to the protective frame 8 of the bridge crane\u2019s sliding contact line, thereby ensuring that it moves in unison with bridge crane 1. When bridge crane 1 is driven by the travelling mechanism 2, it can move along the bridge crane track 7 in a specific manner. What is the result of this? The result is that subsequent installation operations can be carried out with ease.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>59. The conductor rail bracket 3, fitted with a conductor rail, is positioned at the point where it is secured to the pre-embedded base plate 6 of the rock-anchored beam, whilst the conductor rail is held in place within the conductor rail mounting clamps 4 on the conductor rail bracket 3.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>60. Foundation slab 6 is embedded at the rock-anchored girder; it is intended to connect with the metal plate within the girder installed on the bridge crane track 7. The purpose of this connection is to facilitate sliding contact.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>Install along the line.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>61. The conductor rail bracket 3 is used to secure the conductor rail mounting clamp 4, whilst the conductor rail is secured within the conductor rail mounting clamp 4. In this embodiment, both the conductor rail bracket 3 and the conductor rail mounting clamp 4 are prior art; a person skilled in the art can carry out the installation directly using existing structures, without the need for further explanation.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>62. In this embodiment, the positioning of the conductor rail bracket 3 is primarily carried out using the conductor rail installation and commissioning device, which comprises a vertical plate, a fixing assembly, a conductor rail elevation positioning crossbar 12, and a conductor rail position positioning ruler 13.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>63. The fixing assembly secures the vertical panel to the bridge crane conductor rail guard 8;<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>64. The vertical plate is installed in a vertical position; its function is to secure the entire sliding contact line installation and commissioning assembly. The vertical plate may be connected to the bridge crane sliding contact line protective frame 8 in a variety of ways, such as by direct welding, bolting or using clamps.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>65. There is a sliding contact line elevation positioning crossbar 12, which is fixed perpendicular to the vertical plate. The sliding contact line elevation positioning crossbar 12 is installed horizontally and is situated below the sliding contact line bracket 3.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>66. The sliding contact rail position gauge 13 is connected to the sliding contact rail elevation positioning crossbar 12; the sliding contact rail position gauge 13 is positioned so that it lies flush against the sliding contact rail mounting clamp 4.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>67. The sliding contact line elevation positioning crossbar 12 is primarily used to position the sliding contact line bracket 3 in terms of height, whilst the sliding contact line positioning ruler 13 is primarily used to position the sliding contact line mounting clamp 4 in terms of position.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>68. Various structures may serve as fixed components; a particularly good example of a fixed component is given below.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>69. The fixing assembly comprises a U-shaped clamp 10 and a horizontal height-adjustment screw 11; to allow this fixing assembly to be fitted, a long vertical through-hole has been provided in the vertical panel.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>70. The U-shaped clamp 10 is fixedly connected to the bridge crane conductor rail guard 8. Under normal circumstances, the bridge crane conductor rail guard 8 consists of multiple horizontal round rods, to which the U-shaped clamp 10 is secured by clamping onto them.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>71. The horizontal elevation adjustment screw 11, which connects the U-shaped clamp 10 to the vertical plate, One end of the horizontal elevation adjustment screw 11 is fixedly connected to the U-shaped clamp 10, whilst the other end passes through the long through-hole and is fixedly connected to a matching nut; the horizontal elevation adjustment screw 11 is capable of sliding up and down along the long through-hole.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>72. Move the vertical plate up or down to adjust the position of the crossbar 12, which is used for the elevation alignment of the sliding contact line; by securing the vertical plate with a nut, the position can ultimately be fixed.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>73. There are several long through-holes; the number of these is unspecified. The number of fasteners is the same as the number of long through-holes; the two are equal.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>74. Providing multiple through-holes helps to ensure a more secure fastening.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'><img decoding=\"async\" style='max-height:800px;max-width:80%;margin: 10px auto' src=\"\/wp-content\/uploads\/2026\/08\/1786451233219_1.jpg\" alt=\"\u8d77\u91cd\u673a\u5b89\u5168\u6ed1\u89e6\u7ebf\u652f\u67b6\u6279\u91cf\u94c6\u710a_\u6865\u5f0f\u8d77\u91cd\u673a\u6ed1\u89e6\u7ebf\u5feb\u901f\u5b89\u88c5\u88c5\u7f6e\u53ca\u65b9\u6cd5_\u6865\u5f0f\u8d77\u91cd\u673a\u6ed1\u89e6\u7ebf\u5b89\u88c5\u6548\u7387\u63d0\u5347\u6280\u672f\" \/><\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>75. Furthermore, under normal circumstances, overhead travelling crane 1 requires multiple conductor rails; therefore, several conductor rail brackets 3 must be added, and the number of conductor rail brackets 3 must be set to match the number of conductor rails. The multiple conductor rail brackets 3 are securely connected from top to bottom to the embedded foundation plate 6 of the rock-anchored girder, and the spacing between any two adjacent conductor rail brackets 3 is equal.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>76. The diagram shows a configuration comprising four conductor rails; it can be seen that there are four conductor rail brackets 3, which are fixed in sequence to the pre-embedded base plate 6 of the rock-anchored girder.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>77. Under normal circumstances, equal spacing is used; whilst this is the obvious approach in practice, it can also be adjusted according to the specific circumstances.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>78. The number of sliding contact line elevation positioning cross-bars 12 is the same as the number of sliding contact line brackets 3; There are several conductor rail elevation positioning crossbars 12, all of which are securely connected to the vertical panels from top to bottom, and the spacing between any two adjacent conductor rail elevation positioning crossbars 12 is the same.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>79. Accordingly, given that positioning is required for each conductor rail bracket 3, a corresponding number of conductor rail elevation positioning cross-bars 12 must be installed. This is achieved by spacing the conductor rail brackets 3 and the conductor rail elevation positioning cross-bars 12 apart one by one, thereby ensuring a one-to-one correspondence.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>80. Furthermore, in practice, it may be necessary to adjust the position of the sliding contact line mounting clamp 4 relative to the sliding contact line bracket 3; In this embodiment, the position of the sliding contact rail mounting clamp 4 is determined using the sliding contact rail positioning gauge 13; during use, simply position the sliding contact rail mounting clamp 4 close to the sliding contact rail positioning gauge 13.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>81. The sliding contact rail positioning ruler 13, by means of the locking screw 16, forms a sliding connection with the sliding contact rail elevation positioning crossbar 12.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>82. In this embodiment, the position of the conductor rail bracket 3 is determined using the conductor rail elevation positioning crossbar 12. Generally speaking, given that conductor rail mounting clamps 4, a conductor rail positioning gauge 13, it is not possible to align them directly; consequently, a height difference of 80 mm is generally maintained. It is therefore necessary to install a fixed-height positioning block 15 between the conductor rail elevation positioning crossbar 12 and the conductor rail bracket 3; the lower end of the fixed-height positioning block 15 is securely connected to the conductor rail elevation positioning crossbar 12, whilst the upper end of the fixed-height positioning block 15 abuts against the conductor rail bracket 3.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>83. Example 2<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>84. The present invention addresses the following problems known in the prior art: after completing the installation of each conductor rail bracket 3, construction workers must first climb out from the operating platform, then move the installation platform, before they can commence work on installing the next bracket. During work at height, the installation platform is frequently accessed and moved; this construction process presents significant safety hazards, and the inconvenience involved in moving the installation platform results in reduced construction efficiency.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>85. There is a quick-installation device for bridge crane conductor rails; in addition to comprising the conductor rail installation and commissioning device as described in Example 1, as well as the conductor rail bracket 3, this device is also equipped with a conductor rail installation platform 5, which is mounted on the bridge crane conductor rail protective frame 8, and the sliding contact line installation and commissioning device is positioned between the sliding contact line installation platform 5 and the pre-embedded foundation plate 6 of the rock-anchored girder.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>86. When installing conductor rail bracket 3, the installer remains on the conductor rail installation platform 5 throughout the process and does not need to move about frequently. Once the conductor rail has been installed, the conductor rail installation platform 5 can serve as a permanent maintenance platform for the conductor rail.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>87. A sliding contact rail mounting platform 5, featuring a horizontal platform for the installer to stand on, as well as a lifting hook and a vertical rod 9.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>88. The hook is connected to the bridge crane\u2019s conductor rail via a protective frame 8; there is a vertical rod 9 which connects the hook to the horizontal support plate.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>89. Install a horizontal platform on the bridge crane\u2019s conductor rail guard 8 that is suitable for standing on; during conductor rail installation, this platform moves in tandem with the bridge crane 1, thereby enabling the installation of conductor rails at different positions.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>90. The width of the conductor rail mounting platform is less than the distance between the bridge crane\u2019s conductor rail guard and the embedded base plate of the rock-anchored girder. To prevent the conductor rail mounting platform from scraping against the embedded base plate of the rock-anchored girder whilst the bridge crane is in motion, this distance is set to at least 100 mm.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>91. Safety railings have been installed on both sides of the horizontal platform, and ladders have been provided to access the rock anchor beams. When it is necessary to stand on the horizontal platform, one can access the rock anchor beams directly via these ladders.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>92. Example 3<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>93. In this implementation example, based on the rapid installation device for bridge crane conductor rails mentioned above, a method for the rapid installation of bridge crane conductor rails is proposed. This method comprises the following steps: <\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>94. First, construct the sliding contact line installation platform; then set up the sliding contact line installation and commissioning device, along with the three sliding contact line brackets; finally, proceed to steps S1 and 5.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>95. To install the above embodiment, the mounting device is manufactured.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>96.s2: Install the platform (5) for mounting the overhead conductor rail, then connect it to the overhead crane conductor rail guard (8).<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>97. Using a mobile crane, lift the conductor rail installation platform 5 and place it on top of the bridge crane conductor rail guard 8; then, using the lifting hook, suspend it from the crossbar of the bridge crane conductor rail guard 8.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>98.s3: Install the sliding contact line mounting and adjustment device via the sliding contact line mounting platform 5;<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>99. Secure the sliding contact line installation and adjustment device to the bridge crane sliding contact line guard frame 8 using U-clamps 10. It should be positioned at the centre of the sliding contact line mounting platform 5, with the fitters standing at either end of the mounting platform to facilitate the installation work.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>100. At the point where the sliding contact line bracket 3 is to be installed, adjust the vertical position of the horizontal bar 12 used to set the elevation of the sliding contact line.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>Position it and ensure it remains level;<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>101. Ensure that the elevation reference bar 12 of the sliding contact line is horizontal. Place a spirit level 14 against the horizontal elevation adjustment screw; check that the bubble in the spirit level 14 is centred before proceeding.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>102. If it is not level, adjust the angle between the vertical panel and the bridge crane conductor rail guard 8 to ensure that it is level.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>103. Set the elevation of the sliding contact rail positioning crossbar 12 to a position 80 mm below the underside of the sliding contact rail bracket 3 using the horizontal elevation adjustment screw. There is a slotted hole at the horizontal elevation adjustment screw 11, adjustments must be made via the sliding contact line installation adjustment device at this slot.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>104. Align the conductor rail to be installed with the position of conductor rail bracket 3, and use the horizontal positioning gauge 13 attached to the bracket to adjust the position of the conductor rail.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>105. Depending on the location where the conductor rail is to be installed, position the conductor rail positioning gauge 13 along the conductor rail elevation positioning crossbar 12, and finally secure it in place using the locking screw 16.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>106. Fit the fixed-height positioning block 15, used to determine the position of the conductor rail bracket 3, onto the conductor rail elevation positioning crossbar 12, with the crossbar in position s6.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>107. This positioning block 15, which has a fixed height, can be installed during step s1; and, as in this embodiment where four layers of sliding contact rails are provided, the fixed-height positioning block 15 can be installed by selecting only the elevation positioning crossbar 12 located on the uppermost sliding contact rail.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>108. Place the conductor rail bracket 3 horizontally on top of the positioning block 15 at the fixed height, and weld the conductor rail bracket 3 to the pre-embedded foundation plate 6 of the rock-anchored beam.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>109. There is a sliding contact line bracket 3, which is positioned on top of a positioning block 15 set at a fixed height of 80 mm. One end of the conductor rail bracket 3 is positioned to align with the top of the conductor rail positioning gauge 13. A hand-held spirit level 14 is then used to adjust the conductor rail bracket 3 to a vertical position, after which the bracket 3 is securely welded to the pre-embedded foundation plate 6 of the rock-anchored beam.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>110. To fit the conductor rail mounting clamp 4, carry out the installation of the clamp 4 in accordance with the position indicated by the positioning ruler 13.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>111.s9: Along the overhead crane rail 7, move overhead crane 1; overhead crane 1 pulls the overhead crane slip ring protection frame 8, moving it to the installation position for the next slip ring bracket 3.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>112. Once the temporary power supply is connected, the travelling mechanisms 2 on both sides of Gantry Crane 1 begin to operate, using the temporary power supply to set Gantry Crane 1 in motion, moving the entire Gantry Crane 1 towards the installation site of the next conductor rail bracket 3, thereby achieving the objective of relocating the conductor rail installation and commissioning unit to the position of the next conductor rail bracket 3.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>113. Repeat steps s7 to s9 continuously until all sliding contact rail brackets 3 have been installed; only then should you stop repeating this action.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>114. Step by step, repeat the above operations in sequence to successfully install each of the three slip ring brackets. (Note: Punctuation included.)<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>115. Return the bridge crane to position 1 and restore it to its initial state, then install the conductor rails onto the conductor rail brackets 3 one by one in sequence.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>116. Once the third conductor rail bracket (3) has been installed, move the bridge crane (1) back to the position of the first conductor rail bracket (3), fit the four-layer conductor rail onto the conductor rail bracket 3, adjust the length of the conductor rail end at the first conductor rail bracket 3 to comply with the drawing specifications, and secure it to the conductor rail mounting clamp 4; then tighten the bolts to secure the conductor rail.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>117. Using the same installation method, move overhead crane 1, then install the conductor rail, continuing in this manner until the installation is complete.<\/p>\n<p style='margin-bottom:24px;color:#555555;font-size:16px;line-height:200%;text-indent:2em'>118.
