A cable tray installation structure

Abstract

The present application relates to an installation structure of a cable bridge, which includes a plurality of bridge bodies, a mounting frame is installed between two adjacent bridge bodies, and the two ends of the mounting frame are respectively fixed on the ground and the top of the wall. The installation frame includes a horizontal plate, the bottoms of the opposite ends of the adjacent two bridge bodies are respectively fixed with first inserts, the top of the horizontal plate is provided with two first slots, and the two first inserts The blocks are respectively plugged into the two first slots; an inner cavity is opened in the horizontal plate, and first through holes are respectively opened on both sides of the inner cavity, and the two first through holes are respectively slidably connected. There is a first limiting block, the opposite inner sides of the two first inserting blocks are respectively provided with first limiting slots, and the two first limiting blocks are respectively inserted into the two first limiting slots; A driving device for driving the two first limit blocks to move back or toward each other is installed in the inner cavity. The present application can reduce the possibility of shaking of the cable tray.

Description

technical field [0001] The present application relates to the technical field of cable laying, in particular to an installation structure of a cable tray. Background technique [0002] At present, cable laying refers to the process of laying and installing cables along surveyed routes to form cable routes. According to the application occasion, it can be divided into several laying methods such as overhead, underground (pipeline and direct burial), underwater, wall and tunnel. Reasonable selection of cable laying method is very important to ensure the transmission quality, reliability and construction maintenance of the line. The city distribution cables can be laid overhead or on the wall. [0003] Related technologies can refer to the Chinese utility model patent with the authorized announcement number CN204441814U, which discloses a cable bridge and a bridge assembly using the cable bridge. The cable bridge includes a left side plate and a right side plate, and at least...

AI Technical Summary

Problems solved by technology

The utility model solves the problem in the prior art that the weight of the cable bridge is large and the production cost is high because the length of the bottom plate is consistent with that of the left and right sides

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: the lower connector is hooked on the upper connector, so that the cable tray is prone to shaking, which may cause safety accidents
