Abstract

An adaptable combined rail -ending insulator involves the field of railway technology, which includes the first outer board, the second outer plate, and the mezzanine; the first outer board, the second outer layerThe board and mezzanine plate are composed of the head, connection, and tail, and the shape of the shape and the rails is adapted;The material rigidity of the second outer plate is higher than that of the shredder.It is composed of a three -layer structure. The outer plate material is not easy to deform, and the mezzanine has good elasticity. After uninstallation, the recovery is strong; when the squeezing pressure of the steel rail end is squeezed and reducedAfter the release, the mezzanine plate can be easier to recover; it can well adapt to the changes of the rails between the rails, exert a stable insulating effect, and ensure the safety of the railway line.

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...
