Combined cable bridge flexible compensation device

Abstract

The invention discloses a combined cable bridge flexible compensation device, which comprises a first panel and a compensation plate; one side of the first panel is provided with a second panel; an embedded mesh layer is respectively fixed inside the first panel and the second panel; the respective surface connection end of the first panel and the second panel is welded with a connection hinge; afastening bolt is arranged through the interior of the connection hinge; the left and right side walls of the first panel and the second panel are respectively welded with a side plate; the inner sideof the compensation plate is provided with a screw in a penetration manner; and the compensation plate is located below the second panel. In the combined cable bridge flexible compensation device, the bottom sealing plate itself has good compression and extension capability, carries out corresponding deformation matched with the telescopic expansion of the bridge body, and has the same function as the arc structure of the first panel and the second panel, both of which weaken the direct stretching action of the bridge body to the cable, and separate the cable from the bridge body so as to avoid excessive friction between the cable and the bridge body, resulting in cable damage.

Description

technical field [0001] The invention relates to the technical field of cable bridge expansion and contraction compensation, in particular to a combined cable bridge expansion and contraction compensation device. Background technique [0002] Cable, made of one or more mutually insulated conductors and an outer insulating protective layer, is a wire that transmits electricity or information from one place to another. Cables play a very important role in modern people's lives, and It is becoming an indispensable part of people's daily life. Cable laying faces many situations. Among them, cable crossing bridge is a very common construction method, but bridges will appear in various forms during the cumulative use Deformation, such as deformation caused by pressure or deformation caused by temperature, in consideration of this situation, it is necessary to leave a reserved length for the laying of cables on the bridge deck to compensate for the deformation of the bridge frame.

Problems solved by technology

[0004] The purpose of the present invention is to provide a combined cable bridge expansion and contraction compensation device to solve the problem that the existing cable bridge expansion and expansion compensation device proposed in the above background technology does not completely solve the problem of cable expansion and contraction compensation when arranging and arranging cables. All the problems faced in the process, such as the actual expansion compensation of the cable cannot be directly obtained, secondly, the strength of the cable layout is poor, and the cable performs expansion and contraction compensation with the deformation of the bridge body. In this process, the bridge body affects the cable itself Due to wear and tear, the service life of the cable is not long, and the automatic expansion and compensation ability of the cable is poor, and the immediacy of extension and retraction is poor.
