Installation structure of cable bridge

Abstract

The invention relates to an installation structure of a cable bridge. The installation structure comprises a plurality of bridge bodies. A mounting frame is mounted between every two adjacent bridge bodies. The two ends of the mounting frame are fixedly connected to the ground and a wall top respectively. The mounting frame comprises a horizontal plate, first inserting blocks are fixedly connectedto the bottoms of the opposite ends of every two adjacent bridge bodies respectively, two first inserting grooves are formed in the top of the horizontal plate, and the two first inserting blocks areinserted into the two first inserting grooves respectively. An inner cavity is formed in the horizontal plate, first through holes are formed in the two sides of the inner cavity correspondingly, first limiting blocks are slidably connected into the two first through holes correspondingly, first limiting grooves are formed in the opposite inner sides of the two first inserting blocks correspondingly, and the two first limiting blocks are inserted into the two first limiting grooves correspondingly. A driving device for driving the two first limiting blocks to move back to back or face to faceis mounted in the inner cavity. According to the invention, the possibility of shaking of the cable bridge can be reduced.

Description

technical field [0001] The present application relates to the technical field of cable laying, and in particular, to an installation structure of a cable tray. Background technique [0002] Currently, cable laying refers to the process of laying and installing cables along a surveyed route to form a cable route. According to the occasion of use, 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 distribution cables in the city can be laid in the overhead and on the wall. [0003] For related technology, reference may be made to the Chinese utility model patent with the authorized publication number CN204441814U, which discloses a cable tray and a tray assembly using the cable tray. The cable tray includes a left side plate and a right si...

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
