Description

Technical Field

[0001] This utility model relates to the field of power transmission line technology, specifically a power transmission line construction crossing frame. Background Technology

[0002] A crossing frame is a special support structure used for power lines or railways to cross obstacles. Its main function is to support power lines, etc. During the construction of transmission lines, it is often necessary to cross various obstacles such as highways, railways, broadcasting lines, and power lines. In order to prevent damage to the conductors and to ensure the safe operation of the objects being crossed, crossing frames are erected at these crossing points before the lines are laid to facilitate smooth construction.

[0003] Currently, traditional crossing frames, such as bamboo frames, are cumbersome to assemble, inefficient, require a large area, and lack stability. While prefabricated iron frames are relatively sturdy, they lack flexibility, have a limited range of motion, and are difficult to adapt to complex and changing construction environments, thus affecting the efficiency of power transmission line construction. Therefore, there is an urgent need to design a new type of crossing frame for power transmission line construction to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a crossing frame for power transmission line construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The inner walls of the support frames are all fixed with grids, and a connecting seat is fixed to the inner wall of the support frame at one end of the outer wall of the grid. The connecting seat is fixedly connected to the top of the support frame by screws.

[0011] Furthermore, the reinforcement assembly includes reinforcement seats that are fixedly connected to both sides of the top of the U-shaped fence by screws, and one end of each reinforcement seat is fixed with a steel rope. One end of two adjacent steel ropes is fixedly installed on one side of the same support frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this utility model, the bridging frame structure is reasonably designed, which greatly improves the installation efficiency compared with the traditional bamboo frame. At the same time, through the synergistic effect of the reinforcing components, including the reinforcing base, steel rope, reinforcing plate and stop, the overall stability is effectively enhanced, overcoming the problem of insufficient stability of the traditional bridging frame.

[0016] In this invention, the walking mechanism allows the crossing frame to slide on the slide rail, greatly improving its flexibility and increasing its range of motion.
