Shock pad for tracks

Abstract

The invention discloses a shock pad for tracks. The shock pad comprises a shock pad body, wherein the shock pad body is divided into a rubber shock absorption layer, a heat insulating layer, a heat reflection plate and a sand and gravel dampproof layer from top to bottom in sequence; the surface of the shock pad body is shaped like a rectangular pyramid formed by four bevels; a plurality of trapezoidal shock absorption pyramids are arranged on the surface of the shock pad body; the upper surfaces of the trapezoidal shock absorption pyramids are on a same plane; a heating chamber is arranged outside the heat insulating layer; a self-regulating heating electric tracing band is wound around the heating chamber; an oil storage device is arranged in the heat insulating layer; a liquid level control meter is arranged at the side, close to the heat insulating layer, of the oil storage device; an oil outlet is formed in the side, close to the heating chamber, of the oil storage device; a dampproof pad is arranged at the bottom 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 damping 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 a rail shock absorber, which can reduce the damage of the shock absorber in cold seasons and solve the above problems. [0004] To achieve the above object, the technical scheme of the present invention is ...
