An antifreeze mat for tracks

Abstract

The invention discloses an antifreeze pad for a track. The antifreeze pad for the track comprises an antifreeze pad main body, wherein the antifreeze pad is divided into three layers, which are a rubber shock absorption layer, a carbon fiber heating layer and a sand moisture-proof layer in sequence from top to bottom; a water accumulating compartment is arranged in the middle of the rubber shock absorption layer; one end of the water accumulating compartment is provided with a drainage channel; the drainage channel is communicated with outside; the surface of the antifreeze pad main body is formed by four inclined planes; the four inclined planes face towards the water accumulating compartment; a plurality of trapezoidal shock absorbing cones are arranged on the surface of the antifreeze pad main body; a hollow spacing layer is arranged between the surface of the antifreeze pad and the rubber shock absorption layer; a circuitous wire slot is formed in the carbon fiber heating layer; a carbon fiber heating wire is laid in the wire slot; the bottom of the sand moisture-proof layer is provided with a moisture-proof pad; and the top of the sand moisture-proof layer is provided with a heat-reflecting plate. Through the adoption of the antifreeze pad for the track, disclosed by the invention, the damage degree of the antifreeze pad can be reduced in cold seasons.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to an antifreeze pad for rails. 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 an antifreeze pad for rails, 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 fo...
