Anti-freezing and shock-absorbing pad for track

Abstract

The invention discloses an anti-freezing shock pad for a rail. The anti-freezing shock pad comprises a shock pad body which is divided into three layers sequentially including the rubber shock absorption layer, the thermal insulation layer and the gravel damp-proof layer from top to bottom. A water accumulation hidden cell is arranged in the middle of the rubber shock absorption layer. A water drainage channel is arranged at one end of the water accumulation hidden cell and is communicated with the outer portion. The surface of the shock pad body is formed by four inclined faces facing the water accumulation hidden cell. A plurality of trapezoid shock absorption cones are arranged on the surface of the shock pad. A heating chamber is arranged between the surface of the shock pad and the rubber shock absorption layer. Resistance heating sticks are arranged in the heating chamber. A damp-proof pad is arranged at the bottom of the gravel damp-proof layer. A thermal reflection plate is arranged on the top of the gravel damp-proof layer. The damage degree of the anti-freezing shock pad can be reduced in cold seasons.

Description

Technical field [0001] The invention relates to the technical field of transportation, in particular to a track antifreeze shock-absorbing pad. Background technique [0002] In rail transit, in the process of high-speed contact between the wheel and the track, a large amount of impact energy will inevitably be generated and a huge noise will be emitted. 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. After a period of use, the shock absorbing effect becomes weaker and the noise emitted increases. Summary of the invention [0003] The present invention aims to provide a track antifreeze damping pad, which reduces the damage of the damping pad in cold seasons and solves the above problems. [0004] In order to achieve the above objective, the technical solution of the pre...
