Base plate with wear monitoring function and rail fastener

Abstract

The invention, which relates to a tramcar, provides a base plate with a wear monitoring function. The base plate with the wear monitoring function comprises an elastic composite base plate and an external circuit. The elastic composite backing plate comprises a drag reduction layer arranged on the top side and an elastic layer arranged on the bottom side; the elastic layer is made of a conductivethermoplastic elastomer material; the drag reduction layer is made of an insulating polymer wear-resistant material; and at least one protrusion is arranged on the top side of the elastic layer and each protrusion is embedded into the drag reduction layer. One end of the external circuit is connected to the elastic layer, and the other end of the external circuit is used for being connected to a steel rail installed on the drag reduction layer; when the drag reduction layer is abraded and the steel rail makes contact with at least one protrusion, the external circuit, the steel rail and the elastic layer form a circuit loop, and an alarm device of the external circuit sends an alarm signal. The invention further provides a rail fastener. Therefore, on the basis of an improved base plate structure, the wear condition of the base plate can be monitored.

Description

technical field [0001] The invention relates to the field of wheel-rail transportation, in particular to a backing plate and a rail fastener with wear monitoring function. Background technique [0002] Backing plates are commonly used accessories for track fasteners. Backing plates are usually placed under the rails to cushion the rails. Due to the relative movement of the rails and the backing plate, the backing plate is often worn. However, since the backing plate is arranged under the rail, its wear position and degree of wear cannot be observed directly. Therefore, in the process of railway maintenance, it is difficult to find and replace worn backing plates in time, which may cause the risk of direct contact between the base plate of the track fastener and the rail. Contents of the invention [0003] In order to solve the above technical problems or at least partly solve the above technical problems, the present invention provides a backing plate and a track fasten...
