Bridge convenient to overhaul

Abstract

The invention discloses a bridge convenient to overhaul, belonging to the technical field of power equipment. The bridge comprises a U-shaped shell and a cover plate, wherein the cover plate comprisestwo cross beams, a left panel, a middle panel and a right panel; the cross beams are close to the front end and the rear end; wall grooves for pressing the cross beams are formed in the side wall ofthe shell; the three panels are sequentially arranged on the cross beams and are rotationally connected through a rotating shaft; the left panel is fixedly connected with the cross beams, the right end faces of the right panel and the cross beams are provided with connecting holes corresponding in position, and fixing is achieved by inserting two arms of a U-shaped rubber connecting piece into theconnecting holes; the left side face of the left panel and the right side face of the right panel are provided with outwards-protruding inserting plates which vertically extend downwards at positionsbetween the two cross beam; slots are formed in the corresponding positions of the shell; and each slot is composed of a shell side plate, a first groove plate which is vertically led out from the shell side plate, and a second groove plate which is vertically led out from the outer edge of the first groove plate. According to the bridge disclosed by the invention, the interior of the bridge canbe quickly overhauled, operation is convenient and quick, and high safety is realized.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to a bridge frame which is convenient for maintenance. Background technique [0002] As a carrier for laying various cables, cable trays are widely used in petrochemical, metallurgy, electric power, schools, hospitals, communications, high-rise buildings and other fields. [0003] Most of the bridge cover plates on the market are a whole plate. When the bridge needs to be repaired, the whole cover plate needs to be removed. The removed cover plate takes up a considerable amount of installation space, especially when the bridge frame has a considerable height. The up and down handling, installation and dismantling work is time-consuming and labor-intensive, which affects the maintenance efficiency. There are also a small number of structural designs in the market that temporarily fix the entire cover after turning it over, but the placement of the entire cover...

AI Technical Summary

Problems solved by technology

[0003] Most of the bridge cover plates on the market are a whole piece of material. When the bridge needs to be repaired, the whole cover plate needs to be removed. The removed cover plate takes up a considerable amount of installation space, especially when the bridge frame has a considerable height. The up and down handling, installation and dismantling work is time-consuming and laborious, which affects the maintenance efficiency

There are also a small number of structural designs in the market that temporarily fix the whole cover after turning it over, but the placement of the whole cover at an angle is more or less dangerous. Once a structural defect occurs after long-term use, it will easily lead to a safety accident
