Method and tool for mounting brake system pipeline of aluminum alloy vehicle

Abstract

The invention provides a method and tool for mounting a brake system pipeline of an aluminum alloy vehicle. The method comprises the following steps of: manufacturing the tool; arranging pipe clamp anchors on pipe clamp anchor brackets respectively and fastening; arranging pipe clamps on the pipe clamp anchors according to a requirement; connecting the brake system pipeline and contacting end parts of the brake system pipeline with positioning baffle plates; fixing the brake system pipeline on the pipe clamp anchors by using the pipe clamps; performing wind pressure test on the brake system pipeline to check the airtightness of the pipeline; disassembling a whole body which consists of the pipe clamp anchors, the pipe clamps and the brake system pipeline from the pipe clamp anchor brackets; and hoisting the whole body to the bottom of the aluminum alloy vehicle. By the technical scheme, the brake system pipeline can be preassembled on the ground, the overall pipeline can be assembled into a module which is completely matched with a chassis of a vehicle by using the pipe clamps and the pipe clamp anchors, and the module is hoisted to a hoisting position of a frame. The method is easy to operate and high in mounting efficiency.

Description

technical field [0001] The invention relates to rail vehicle technology, in particular to a pipeline installation method and tooling for an aluminum alloy vehicle braking system. Background technique [0002] The pipeline of the rail vehicle braking system is used as a tool for the pneumatic device to transmit air. Its airtightness directly affects the performance of the braking system. It runs through the whole section of the vehicle. If the traditional pipeline assembly method is used, the pipelines are assembled one by one on the vehicle. After all the pipelines are connected, the pipe clamps are tightened again. This requires the cooperation of multiple people to complete, which is not only difficult to operate, but also wastes A large number of working hours will conflict with other processes, which is more likely to cause pipeline leakage, make it difficult to find, and affect the production schedule. [0003] The existing technical solution is to put all the pipes in...

AI Technical Summary

Problems solved by technology

[0004] Due to the existence of the vehicle underframe beam, the pipeline can be temporarily erected in the oval hole of the underframe beam, which is convenient for assembly. The disadvantage of this assembly scheme is that it is difficult to determine the location of the pipeline, which can only be measured on site, and the error is relatively large , after all the pipelines are adjusted and connected, the pipe clips can be fastened, which is difficult to operate and wastes man-hours. For stainless steel vehicles, this assembly method can only be used; for aluminum alloy vehicles, this assembly scheme is more difficult. Operation, due to the existence of the elliptical hole in the crossbeam without the bottom frame, and the size of the large row of pipelines is long, when assembling, it needs many people to lift, lift and other human-assisted forms to assemble the pipelines, resulting in a waste of human resources, and because the pipe wall Thinner and lower strength, it is easy to deform the pipeline, pipeline positioning and installation of pipe joints, which directly affects the airtightness of the pipeline
