Low-noise damping rail

Abstract

The invention relates to the technical field of rail traffics, in particular to a low-noise damping rail. The low-noise damping rail comprises rail bodies and a fixing plate, wherein the top end of each rail body is fixedly connected with a top plate; the bottom end of each top plate is fixedly connected with a supporting plate; one side of each supporting plate is fixedly connected with the corresponding rail body; the inner side of each supporting plate is fixedly connected with a sleeve; the inner side of each sleeve is in sleeve connection with a telescopic tube; the bottom end of each telescopic tube is fixedly connected with a fixing plate; one end of each fixing plate is fixedly connected with a spring; a partition is arranged at the bottom end of each fixing plate; a silencing holeis formed in the inner side of each partition; the bottom end of each fixing plate is fixedly connected with a connecting plate; the bottom end of each connecting plate is fixedly connected with a bottom plate; a fixing block is arranged between the rail bodies; a connecting hole is formed in the outer side of the fixing block; and the top end of the fixing block is fixedly connected with a connecting plate. Noises generated by a train and vibration generated by collision of carriages are reduced. The low-noise damping rail has huge economic benefit and extensive market prospect, and is worthy of being popularized and used.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a low-noise shock-absorbing rail. Background technique [0002] Rail transit refers to a type of vehicle or transportation system that operating vehicles need to run on a specific track. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of trains and railway technologies, There are more and more types of rail transportation, not only in long-distance land transportation, but also in short- and medium-distance urban public transportation. Common rail transportation includes traditional railways, subways, light rails and trams, and new Rail transit includes magnetic levitation track system and monorail system. With the development of society, the application of rail transit is becoming more and more extensive. Therefore, the demand for low-noise and shock-absorbing rails is increasing...

AI Technical Summary

Problems solved by technology

[0003] The traditional railway is connected by rails. Due to the physical properties of thermal expansion and contraction, there must be a gap of a certain width at the junction of the two rails. When the train passes through the gap, the tires of the train will meet the rails. The gap forms an impact, which not only produces noise, but also causes the collision and wear of the rails and train tires, reduces the service life of the rails and train tires, increases the maintenance cost of the train and the rails, and at the same time, the collision of the train will generate a large Vibration brings a sense of bumps to the passengers in the car, affects the comfort of the passengers in the car, and causes environmental pollution and reduces the living conditions of the surrounding people. Therefore, a low-noise shock-absorbing rail is proposed to address the above problems
