Problems solved by technology

[0004] The prior art has no reinforced splint structure, because the turnout is a shallow groove structure, and the flange groove is far away from the rail waist, resulting in a large local force on the rail when the train passes, which is easy to break the rail, shorten the service life, and increase the maintenance cost

Abstract

The invention discloses a trough-type-rail reinforcing structure. The trough-type-rail reinforcing structure comprises a padding plate, a bolt and a nut, wherein the padding plate is arranged on the side, close to a rail web, of a steel rail, and the nut is located on the other side, away from the rail web, of the steel rail; the bolt sequentially penetrates through the padding plate and the steelrail and is in thread fit with the nut. The trough-type-rail reinforcing structure has the multiple advantages that the structure is simple, operation is easy, the practicability is high, the stresscondition of the steel rail is enhanced and improved, and the service life of the steel rail is prolonged.

Description

technical field [0001] The invention relates to the technical field of track maintenance equipment, in particular to a grooved rail reinforcement structure. Background technique [0002] In order to solve problems such as traffic congestion, sharp increase in vehicle exhaust emissions, excessive noise, and serious pollution of urban air quality and environmental quality, urban subways and light rail transportation have played a major role. [0003] With the rapid development of domestic transportation, the rapid development of urban rail transit, Dalian, Shanghai, Shenyang, Zhuhai, Chengdu and other cities have successively built tram lines, and many provinces and cities in my country have the intention or plan to invest in the construction of trams. Modern trams are mainly concentrated in big cities, requiring safe and stable operation and good comfort; at the same time, the control of noise is higher than the requirements of railways, so the wear resistance of the track is...
