Mounting module and mounting method for lower wire pipe of railway vehicle

Abstract

The invention discloses a mounting module and a mounting method for a lower wire pipe of a railway vehicle, the mounting module comprises a connecting part, a supporting part and lower wire pipes, and a plurality of first mounting through holes are formed in the supporting part; the number of the lower wire pipes is the same as that of the first mounting through holes; and one end of the connecting part is connected to a lower edge beam of the side wall, the other end of the connecting part is connected with the supporting part, and the lower wire pipe penetrates through the first mounting through hole. The connecting part is arranged to be connected with the lower edge beam of the side wall, the first mounting through holes are formed in the supporting part, and the lower wire pipes are mounted in the first mounting through holes, so that the lower wire pipes are connected with the supporting part; the connecting part is connected with the supporting part, so that the relative positions of the lower wire pipes and the side wall lower edge beam are fixed, field installation of the lower wire pipe module of the railway vehicle is achieved, field transformation and maintenance of the railway vehicle are facilitated, and the connecting points of all the components are far away from the iron floor, the wood floor and the cold-proof layer. And the construction safety in the railway vehicle cable transformation process is ensured.

Description

technical field [0001] The invention belongs to the technical field of rail vehicles, and in particular relates to a rail vehicle downline pipe installation module and an installation method. Background technique [0002] There are many types of internal equipment and cables in rail vehicles, and a large number of electronic and electrical equipment and cable harnesses are interwoven. When the electrical control cabinet on the rail vehicle supplies power to the lower part of the car body, it is generally designed with a downline pipe. The downline pipe is generally set at the position of the lower side beam of the side wall. The upper part extends into the car body through the wooden floor, and the lower part extends through the iron floor. Going out to the lower part of the car body, it is fully welded to the iron floor. [0003] If the vehicle is not combined with factory repairs for partial modification or other special circumstances that require re-welding of the wire p...

AI Technical Summary

Problems solved by technology

[0003] If the vehicle is not combined with the factory repair for partial modification or other special circumstances need to re-weld the downpipe, the wooden floor at this position must be disassembled, and the wooden floor must be disassembled Decomposing the interior parts covering the upper part of the wooden floor, the cycle and cost are relatively high

At the same time, welding directly on the iron floor makes it difficult to dissipate the heat generated by welding, and the cold-proof layer between the iron floor and the wooden floor is prone to burning, and the ignition point is not easy to be found, which poses a greater safety risk

[0004] Therefore, it is a technical problem to be solved urgently to develop a rail vehicle downline pipe installation module and installation method to solve the problems of inconvenient operation and safety risks.
