Problems solved by technology

[0003] However, in the process of substation erection or operation and maintenance, it is necessary to enter heavy vehicles, such as cranes or lift trucks, etc. When heavy vehicles pass by, it will cause rigid damage to the cable trench cover, making the steel plate unable to achieve the original load-bearing role, so how to Designing a device that is convenient for heavy vehicles to move in the substation and can protect the cable trench cover is a technical problem that those skilled in the art need to solve urgently

Abstract

The invention belongs to the technical field of electric facilities, and particularly relates to a cable trench cover plate bridge. The cable trench cover plate bridge comprises a left cover plate, aleft connecting plate, a middle cover plate, a right connecting plate and a right cover plate from left to right in sequence, the two ends of the left connecting plate are respectively hinged with theleft cover plate, the two ends of the right connecting plate are respectively hinged with the middle cover plate and the right cover plate, a left supporting plate is arranged at the lower end of theleft cover plate, and a right supporting plate is arranged at the lower end of the right cover plate. The cable trench cover plate bridge provided by the invention provides a temporary channel for vehicles, protects a cable trench, and greatly improves the working environment and the working efficiency in a substation, and the folding structure can be conveniently carried on the vehicle, so thatthe flexibility is high.

Description

technical field [0001] The invention belongs to the technical field of electric power facilities, in particular to a cable trench cover plate bridge. Background technique [0002] In the substation environment, there are many vertical and horizontal cable trenches. The span of the cable trench is usually 0.8m-1.2m, and the depth is about 1.2m, and the cable brackets are installed on both sides of the cable brackets, and the transmission cables are laid on the cable brackets; To solve the problem of falling, a cover plate is laid on the upper end of the cable trench to facilitate manual passage. The cover plate adopts a steel structure or a prefabricated concrete structure. [0003] However, in the process of substation erection or operation and maintenance, it is necessary to enter heavy vehicles, such as cranes or lift trucks, etc. When heavy vehicles pass by, it will cause rigid damage to the cable trench cover, making the steel plate unable to achieve the original load-be...
