Problems solved by technology

[0002] The track beams in the related art are exposed in the atmosphere. Due to the interference of weather factors, due to the rainy weather, a water film is formed on the surface of the track beams, resulting in a low surface friction coefficient of the track beams.
When the rail vehicle is running on the track beam, the wheels of the rail vehicle are prone to slipping, and vehicle operation accidents are prone to occur

Abstract

The invention discloses a coating structure for a track beam, a construction method of the coating structure and the track beam. The coating structure comprises a bottom layer, a middle wear-resistantlayer, anti-skid aggregate and a surface layer, the bottom layer is suitable for being arranged on a beam body of the track beam, the middle wear-resistant layer is suitable for being smeared on thebottom layer, the surface layer is arranged on the side, deviating from the bottom layer, of the middle wear-resistant layer, the anti-skid aggregate is located between the middle wear-resistant layerand the surface layer and connected with the middle wear-resistant layer and the surface layer, and the anti-skid aggregate forms a discontinuous fault between the middle wear-resistant layer and thesurface layer to enable the coating structure to form an uneven surface, and the bottom layer is a low-surface-treatment epoxy wear-resistant glass flake paint layer. According to the coating structure, it can be guaranteed that the coating structure has excellent friction force and abrasion resistance, and meanwhile the coating structure is convenient to manufacture and high in production efficiency.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a coating structure for rail beams, a construction method for the coating structure, and rail beams. Background technique [0002] The track beams in the related art are exposed in the atmosphere. Due to the interference of weather factors, a water film is formed on the surface of the track beams in rainy weather, resulting in a low surface friction coefficient of the track beams. When the rail vehicle runs on the track beam, the wheels of the rail vehicle are prone to slipping, and vehicle operation accidents are prone to occur. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the first aspect of the present invention proposes a coating structure that can improve the surface friction coefficient of the track beam at least to a certain extent. [0004] The s...
