[0013] Furthermore, an insulating layer is provided outside the hook.

[0014] Furthermore, the radius of the hook is 170 mm.

[0015] The beneficial effects of the utility model are as follows: the power distribution cabinet fixing bracket device in the utility model has a simple structure, is easy to process and manufacture, and has a low manufacturing cost. The utility model can be directly hung on the installed pipe in the tunnel, saving the cost of manual drilling and installation on the side wall in the early stage, and can realize the temporary convenient fixing and convenient movement of the three-level power distribution cabinet. After the three-level power distribution cabinet is used, the hook can be directly removed from the pipe to move the device to the next construction position, and the movement is convenient and fast. By arranging a U-shaped bracket at the lower part of the power distribution cabinet bracket, the cables around the power distribution cabinet can be placed in the U-shaped bracket in a regular manner, and the bridge of the cable trough is realized, which ensures the construction safety and saves the cost of installing the cable trough in the later stage. By arranging an insulating layer on the outside of the hook, the device can be insulated from the pipeline to avoid leakage of the power distribution cabinet and cause risks to the construction personnel in the tunnel. The power distribution cabinet fixing bracket device in the utility model can be standardized and manufactured in the factory, which can make the temporary installation of the power distribution cabinet in the tunnel more standardized, and the utility model can be reused, which can save construction costs.
