Antifreeze shock absorber for railway tracks

Abstract

The invention discloses an antifreezing shock pad for rails. The shock pad comprises a shock pad body, wherein the shock pad body is divided into the following three layers from top to bottom in sequence: a rubber shock absorption layer, a heat insulating layer and a sand and gravel dampproof layer; a water accumulation concealed compartment is arranged in the middle of the rubber shock absorption layer; a drainage channel is arranged at one end of the water accumulation concealed compartment and is communicated to the outside; the surface of the shock pad body is formed by four bevels; the four bevels face the water accumulation concealed compartment; a plurality of trapezoidal shock absorption pyramids are arranged on the surface of the rubber shock absorption layer; a dampproof pad is arranged at the bottom of the sand and gravel dampproof layer; and a heat reflection plate is arranged at the top of the sand and gravel dampproof layer. The shock pad has the beneficial effect that the degree of damage of the shock pad in cold seasons can be reduced.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a rail antifreeze and shock absorbing pad. Background technique [0002] In rail transit, during the high-speed contact between the wheel and the track, it will inevitably generate a large amount of impact energy and make a huge noise. In order to reduce the noise during the running of the vehicle, rubber rings are often lined under the track at present, but in China The railway load is heavy, the actual service life of the rubber shock absorbing ring is short, and it is troublesome to replace it. After a period of use, the shock absorbing effect becomes weaker and weaker, and the noise emitted increases. Contents of the invention [0003] The present invention aims to provide a rail antifreeze shock absorbing pad, which can reduce the damage of the shock absorbing pad in cold seasons and solve the above problems. [0004] To achieve the above object, the technical sche...
