[0002] When building a tunnel, cable trays are often used to lay cables. The cable trays are formed by connecting cable tray members end to end. The original cable trays had relatively single functions and were only used for cable laying. With the development of cruise robots, modern cable trays now have an additional function. They are not only used for cable laying but also serve as cruise rails for cruise robots. Carrying cruise robots places higher requirements on the strength and load-bearing capacity of the cable trays. A cover plate is often provided on the cable tray members. In the existing technology, the cover plate is fixed to the cable tray members with screws, but this fixing structure is troublesome to disassemble and assemble.

[0003] In the prior art, for example, a cable tray structure disclosed in the patent application with the application number CN202321502006.X and the name "An Adjustable Tunnel Lighting Cable Tray" includes a cable tray body, a protective cover, and a bracket. The protective cover is arranged above the cable tray body. However, the protective cover is only placed on the cable tray body without a reliable fixing structure designed. Therefore, the installation structure of the cable tray cover plate needs to be further improved. Summary of the Utility Model

[0033] As Figures 1 to 6 shown, a bridge cover plate installation structure includes a bridge component 1 connected end to end. Guide rails 11 are respectively formed on both sides of the upper end of the bridge component 1. The bridge component 1 is equipped with a cover plate 2. Insertion slots 1a are punched on both sides of the bridge component 1. An insertion portion 21 adapted to the insertion slot 1a is provided on the cover plate 2. An anti-detachment portion 11a is formed by bending the upper surface of the guide rail 11 downward along the position of the insertion portion 21.

[0034] Handle slots 2a are arranged on the cover plate 2 at intervals. The handle slots 2a are arranged at positions close to the end faces at both ends of the cover plate 2. Since the cover plates 2 are also connected end to end, the arrangement of the handle slots 2a facilitates the application of force when the cover plate 2 is disassembled.

[0035] The cover plate 2 is provided with first reinforcing ribs 2b at intervals.

[0036] The reinforcing ribs 2b are arranged along the width direction of the cover plate 2.

[0037] The setting of the first reinforcing ribs 2b can improve the strength of the cover plate 2.

[0038] Both sides of the cover plate 2 are bent to form flanges 22, and the insertion portions 21 are arranged on the flanges 22. The setting of the two flanges 22 can also improve the strength of the cover plate 2, and the flanges 22 extend downward to form the insertion portions 21.

[0039] The bridge member 1 is provided with second reinforcing ribs 1b at intervals.

[0040] The second reinforcing ribs 1b are arranged along the width direction of the bridge member 1.

[0041] The setting of the second reinforcing ribs 1b can improve the strength of the bridge member 1.

[0042] The bridge member 1 is provided with mounting grooves 1c at intervals along the length direction. The setting of the mounting grooves 1c facilitates the installation of accessories such as brackets, lighting fixtures, and cameras. Along the length direction of the bridge member 1, a plurality of mounting grooves 1c are provided, and the installation position can be selected and adjusted as needed during installation.

[0043] A positioning member 3 is arranged between adjacent bridge members 1. An inner cavity is formed in the guide rail 11, and both ends of the positioning member 3 are respectively inserted into the inner cavity of the guide rail 11 of the bridge member 1.

[0044] The cross-section of the positioning member 3 is of a square structure. The cross-section of the corresponding inner cavity of the guide rail 11 is also of a square structure. The use of a square structure enables both the upper surface and the side surface of the guide rail 11 to be used as the support surfaces for the rollers of the cruise robot. At the same time, when installing the positioning member 3, the installation direction does not need to be considered, and the installation is more convenient.

[0045] The bridge cover plate installation structure of the present utility model is connected by the mating insertion of the insertion part 21 on the cover plate 2 and the insertion groove 1a on the bridge piece 1. The insertion connection structure is adopted, which is convenient for disassembly and assembly and has reliable connection. In addition, the upper surface of the guide rail 11 is bent downward along the position of the insertion part 21 to form an anti-disengagement part 11a. That is to say, the upper surface of the guide rail 11 extends the distance of the profile thickness into the vertical installation space of the cover plate 2. In this way, when installing the cover plate 2, the installer needs to press down the cover plate 2 with force against the resistance of the anti-disengagement part 11a to complete the installation, which can ensure that the cover plate 2 is installed in place, prevent the installer from placing the cover plate 2 on the bridge piece 1, and ensure the reliability of the connection. At the same time, after the cover plate 2 is installed, the anti-disengagement part 11a can prevent the accidental disengagement of the cover plate 2; when disassembling the cover plate 2, the installer puts both hands into the corresponding handle grooves 2a and pulls upward with force to remove it.

[0046] The above are only the preferred embodiments of the present utility model, and do not limit the implementation manners and protection scope of the present utility model. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the description and illustrations of the present utility model should be included in the protection scope of the present utility model.
