A track antifreeze pad

Abstract

The invention discloses an antifreezing pad for tracks. The antifreezing pad comprises an antifreezing pad body, wherein the antifreezing pad body is divided into the following three layers from top to bottom in sequence: a rubber shock absorption layer, a carbon fiber heating 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 antifreezing 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 antifreezing pad body; a heat reflection plate is arranged between the surface of the antifreezing pad body and the rubber shock absorption layer; a circuitous slot is formed in the carbon fiber heating layer; a carbon fiber heating wire is laid in the slot; and a dampproof pad is arranged at the bottom of the sand and gravel dampproof layer. The antifreezing pad has the beneficial effect that the degree of damage of the antifreezing pad in cold seasons can be reduced.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a track antifreeze 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 track antifreeze pad, which can reduce the damage of the antifreeze pad in cold seasons and solve the above problems. [0004] To achieve the above object, the technical scheme of the present invention is as follo...
