Track coating device and process method

Abstract

The invention relates to a track coating device and process method. The track coating device comprises a forming roller coating device used for conducting automatic roller coating on a track, a supporting device used for supporting the track and a control system, wherein the outer contour of a forming roller of the forming roller coating device is matched with the outer contour of the track; and the control system is electrically connected with the forming roller coating device and the supporting device. According to the track coating device and process method, one-time roller coating of the three faces of the track is automatically achieved, and the production efficiency is improved to a great extent; the forming roller coating device is completely attached to roller coating of the section of the track, so that the quality is stably improved while the production efficiency is improved; roller coating can be controllably carried out in a quantitative and constant-speed manner, so that splashing and dripping are avoided in the roller coating process, and the roller coating is more environment-friendly; the supporting device is more beneficial to one-time forming roller coating bridge crossing of the track; and through the control system, full-automatic coating is achieved, labor force is reduced, and economic benefits are improved.

Description

technical field [0001] The invention relates to the field of track production, in particular to a track surface coating device and process method. Background technique [0002] With the development of society, the innovation and development of transportation are also changing with each passing day. Rail transit such as light rail and subway shines brightly, and the demand is growing rapidly. They mostly use DC electric traction system and use the running rail as the return line. Most of the current can flow back to the negative pole of the power supply through the running rail, but a small part leaks from the position where the rail and the ground are poorly insulated into the ballast bed and the surrounding soil, forming a stray current. The existence of stray currents will electrochemically corrode the rail itself and the public facilities pipelines and buildings around the track, reducing the service life of the track, buried pipelines and buildings; especially for the ...

AI Technical Summary

Problems solved by technology

However, the surface coating method of the track is mostly manual brushing, which often requires at least three back and forth brushing, and the covering thickness of the protective agent will definitely be uneven.

Except for the upper surface, the other three sides of the track must be coated with protective agent. Manual brushing has the problem of dead angle and flow, which is easy to splash and drip, wastes raw materials and is not environmentally friendly
