antifreeze cushion

Abstract

The invention discloses an anti-freezing shock absorption pad which comprises a shock absorption pad body, wherein the shock absorption pad body comprises a rubber shock absorption layer, a thermal insulating layer, a heat reflection panel and a sandstone damp-proof layer from top to bottom; the surface of the shock absorption pad body is in a rectangular pyramid shape composed of four inclined planes; the surface of the shock absorption pad body is provided with a plurality of trapezoidal shock absorption cones, and the upper surfaces of the trapezoidal shock absorption cones are positioned on the same plane; two springs are fixed in the thermal insulating layer; a heating chamber is arranged at the outer side of the thermal insulating layer, and the heating chamber is wound with a self-limited temperature electric tracing ribbon; and a damp-proof pad is arranged at the bottom of the sandstone damp-proof layer. By adopting the anti-freezing shock absorption pad, the damage degree of the shock absorption pad in a cold season can be reduced.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to an 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 purpose of the present invention is to provide an 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...
