Description

Technical Field

[0001] The utility model relates to the technical field of rubber products, in particular to a rubber pad used for train shock absorption. Background Art

[0002] The high elastic rubber pad used for train shock absorption is the rubber elastic pad, also referred to as the elastic pad. The rubber elastic pad is an important component of the track structure and is installed between the steel and concrete sleepers. Its main function is to buffer vehicle vibration and impact through tracking at high speed, protect the roadbed and sleepers, electrical insulation and signal systems, and additional rubber plates, because they are exposed to the atmosphere for a long time, require good resistance to natural aging and cold and heat resistance. The rubber plate used in the subway has good shock absorption properties, such as low noise.

[0003] Currently, the existing rubber elastic pads on the market are basically straight plate structures, or have buffer grooves on one side. They have poor cushioning and shock absorption performance in load-bearing applications, poor elastic quality, and are not conducive to providing shock absorption for tracks. Therefore, we propose a rubber pad for train shock absorption to solve the above problems. Utility Model Content

[0007] In a further embodiment, two symmetrical arc-shaped grooves are provided on the front side and the back side of the rubber plate body, and a fixing hole is provided on the front side of each arc-shaped groove.

[0008] In a further embodiment, a production mark is fixedly connected to the bottom surface of the rubber plate body, and a transparent film is fixedly connected to the bottom surface of the production mark.

[0009] In a further embodiment, a plurality of pressure relief holes arranged at equal distances are provided on the front and back of the rubber plate body, and a dustproof net is fixedly connected to the inner wall of each pressure relief hole.

[0010] In a further embodiment, a plurality of groups of anti-skid grooves arranged at equal distances are provided on the front side and the back side of the rubber plate body, and the maximum depth of each anti-skid groove is five millimeters.

[0011] In a further embodiment, a plurality of equidistantly arranged partition plates are fixedly connected to the inner wall of the installation groove, and each of the partition plates is made of rubber.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The device can improve the shock-absorbing elasticity of the rubber plate body through the mutual cooperation of the installation groove, the rubber support plate and the rubber spring, thereby improving the shock-absorbing and damping effect of the rubber plate body and improving the stability of the train during travel. The mutual cooperation of the buffer top groove and the buffer bottom groove allows the front and back sides of the rubber pad body to improve the buffering and shock-absorbing performance through structural staggering when carrying the train. The provision of the buffer circular groove allows the rubber pad body to evenly collapse through the internal space when carrying the load, making the train travel more smoothly, thereby achieving the effect of improving the elastic quality of the rubber plate body and providing efficient shock absorption for the train.
