Abstract

A combined rail end insulator capable of adapting to rail gap changes relates to the technical field of railways and comprises a first outer layer plate, a second outer layer plate and a sandwich plate. The first outer layer plate, the second outer layer plate and the sandwich plate are each composed of a head, a connecting part and a tail, and the shapes of the plates are matched with an end surface of a steel rail. The first outer layer plate and the second outer layer plate are used for clamping and fixing the sandwich plate; and material rigidity of the first outer layer plate and the second outer layer plate is higher than that of the sandwich plate, and material elasticity of the sandwich plate is higher than that of the first outer layer plate and the second outer layer plate. The insulator is composed of three layers of structures, an outer-layer plate material is good in rigidity and not prone to deformation, and the sandwich plate has good elasticity and is high in resilienceafter being unloaded; when the insulator is extruded by the end part of the steel rail, the sandwich plate is extruded and shrunk, and the sandwich plate can be easily recovered after an acting forceof the end part of the steel rail is released; and the insulator can well adapt to the change of rail gaps between steel rails, play a stable insulating role and ensure the safety of railway lines.

Description

technical field [0001] The present application relates to the field of railway technology, in particular to a combined rail end insulator that can adapt to rail gap changes. Background technique [0002] In order to ensure the safety of the railway track circuit, insulation treatment is required between the rail joints, and insulators are generally arranged at the rail joints. However, due to thermal expansion and contraction, the length of the rail will vary within a certain range in different seasons, resulting in greater stress on the insulator. Therefore, the insulator must have a certain degree of elasticity and be able to disperse the deformation of the rail to a certain extent. [0003] However, the insulator in the prior art is affected by the material and shape, and has a short service life, which poses a certain threat to the safety of the railway line. [0004] TPU (Thermoplastic polyurethanes) is called thermoplastic polyurethane elastomer rubber. Contents of...
