Description

Technical Field

[0001] The utility model relates to an auxiliary device for laying cables in electric power construction, belonging to the technical field of cable laying. Background Art

[0002] A cable trench is an underground conduit used for laying and replacing power or telecommunication cable facilities. Cable racks are usually fixedly installed on the inner wall of the cable trench to install cables.

[0003] After searching, the patent number CN202022226209.3 discloses an assembled cable trench. It includes an integrally formed trench body, which includes a bottom plate, a top plate, a side plate, a bracket and a boss; the side plate is arranged between the bottom plate and the top plate; the opposite surfaces of the inner walls of the side plates on both sides are relatively provided with multiple groups of brackets arranged vertically, and the top surface of the end of the bracket away from the side plate is provided with a block; a raised boss is provided in the middle of the bottom plate, and a accommodating groove for drainage is formed between the side wall of the boss and the inner wall of the side plate and the top wall of the bottom plate. The assembled cable trench includes a bottom plate, a top plate, a side plate, a bracket and a boss, which are cast as a whole in a processing plant through a special mold, and can be installed and used after being prefabricated in batches and transported to the construction site. This structure has a short construction period, low cost, and simple construction process, thereby shortening the construction period and increasing construction efficiency.

[0004] Although the above patent can realize the basic installation function of the cable, the current technical considerations are not comprehensive and have the following disadvantages:

[0005] When the wall-mounted plate is fixed on the inner wall of the cable trench, the conventional bracket cannot rotate relative to the wall-mounted plate, and the cable clamp cannot rotate from a horizontal state to an inclined state and lock with the rotation of the bracket, nor can it rotate from an inclined state to a horizontal state and lock. However, when laying cables, they often need to turn horizontally or up and down to reach various power connection devices, and since the positions of various power connection devices are different, when the curvature of the bend is large, it is possible to cause damage to the cable insulation layer or the cable core, which will eventually reduce the service life of the cable.

[0006] In order to solve one of the above problems, an auxiliary device for laying cables in power construction is urgently needed. Utility Model Content
