Description

Technical Field

[0001] The utility model relates to the technical field of cable brackets, in particular to a cable bracket for a subway tunnel. Background Art

[0002] Subway is a form of rail transportation, referring to an urban rail transit system that mainly operates underground, that is, the abbreviation of underground railway or underground railway. In order to adapt to the construction environment and consider the construction and operation costs, many such systems will be converted into ground or elevated sections outside the city center. However, with the development of urban rail transit systems, subways sometimes lay part of their routes on the ground due to the construction environment. Modern cables used for power supply and communication are generally laid through trenches and tunnels. As we all know, cable racks are usually required when laying cables.

[0003] Most of the existing brackets can be classified according to the number of cables to be installed, and the brackets corresponding to the number of cables are selected for use. When installing, the brackets are mostly fixed with bolts after drilling holes. When new cables need to be added, the staff needs to drill holes again to install the brackets corresponding to the number of cables to be added, which is not only inconvenient, but also reduces the installation efficiency of the cables by the staff and reduces the applicability of the bracket.

[0004] Meanwhile, some existing cable brackets can only limit the position of cables of one diameter when in use, resulting in poor applicability of the brackets. Not only is the preparatory work before installing the brackets more complicated, but also the installation efficiency of the cables is reduced. Utility Model Content

[0005] The purpose of the utility model is to provide a cable support for a subway tunnel to solve the problems raised in the above background technology.

[0010] Preferably, the surface of the connecting plate is slidably connected to the inner wall of the connecting frame, the connecting frame is designed as an L-shaped structure, and the surface of the positioning rod is slidably connected to the surface of the connecting frame.

[0011] Preferably, a mounting shell is fixedly connected to the bottom of the threaded rod, the mounting shell is designed as a regular hexagon, and the shape of the inner cavity of the mounting shell is a regular hexagon.

The width of the inner cavity of the extrusion frame 4 is greater than the width of the lower fixed shell 2. Under this effect, the extrusion frame 4 and the lower fixed shell 2 can be staggered with each other, thereby reducing the space between the lower fixed shell 2 and the upper fixed shell 3 and the extrusion frame 4, so as to facilitate the limiting of cables of different diameters. The inner wall of the extrusion frame 4 is slidably connected to the surface of the lower fixed shell 2. Under this effect, the lower fixed shell 2 can position the extrusion frame 4 so that it will not easily tilt or shift in position when extruding the cable, effectively improving the extrusion effect of the extrusion frame 4 on the cable, and the top fixed connection of the mounting plate 1 is connected Shell 8, one side of the inner cavity of the connecting shell 8 is fixedly connected with a compression spring 9, and the other end of the compression spring 9 is fixedly connected with a positioning block 10. The bottom of the mounting plate 1 is fixedly connected with a positioning plate 11, and a positioning groove 12 is provided on one side of the positioning plate 11. The inner wall of the positioning groove 12 is slidably connected with the surface of the positioning block 10. Under this action, when the bracket needs to be spliced ​​and used, the positioning block 10 can be embedded in the positioning groove 12 to connect another bracket. There is no need to drill holes in the tunnel again for installation, which is more convenient. One side of the bottom of the positioning plate 11 is an inclined structural design, and one side of the top of the positioning block 10 is an inclined structural design. The positioning plate 11 is used in conjunction with the positioning block 10. Under this action, when the positioning plate 11 is inserted into the interior of the connecting shell 8 The positioning block 10 is guided so that the positioning block 10 can easily enter the interior of the positioning groove 12, and the positioning block 10 will not be easily moved out of the interior of the positioning groove 12 under the cooperation of the positioning groove 12 and the positioning block 10 shape, which effectively improves the stability of the bracket after splicing.

Under this action, the positioning block 10 can be limited, so that the positioning block 10 will not be easily moved out of the interior of the connecting shell 8, which effectively improves the stability of the positioning block 10 when in use, and will not affect the positioning block 10 from entering the interior of the positioning groove 12. The guide rod 13 is located inside the compression spring 9.Under this effect, the compression spring 9 can be guided when it is compressed or rebounded, so that the compression spring 9 will not easily shift in position when in use.

The connection frame 5 is designed as an L-shaped structure, and the surface of the positioning rod 74 is slidably connected to the surface of the connection frame 5. Under this action, when the connection frame 5 is pulled, the connection frame 5 can block the positioning rod 74 under the action of its own shape, so as to prevent the positioning rod 74 from detaching from the surface of the connection frame 5 and affecting the fixing effect of the cable. The bottom of the threaded rod 72 is fixedly connected to the mounting shell 14. The mounting shell 14 is designed as a regular hexagon, and the shape of the inner cavity of the mounting shell 14 is a regular hexagon.
