Problems solved by technology

[0003] However, most of the above-mentioned elastic backing plates are rubber plates, which are greatly affected by temperature, have poor protection effect on sleepers, have short service life, and are inconvenient to recycle.
If the thermoplastic elastic material is used to make the elastic backing plate, although the defect that the rubber plate is greatly affected by the temperature can be overcome, because the groove of the backing plate has sharp angles, the stress of the backing plate is unevenly distributed when it is stressed. thus also affecting the service life
[0004] In the process of realizing the present invention, the inventors found that there are at least defects in the prior art such as poor vibration damping effect, uneven stress distribution, short service life, poor energy saving and environmental protection, etc.

Embodiment Construction

[0018] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0019] According to an embodiment of the present invention, a backing plate for a cushioned sleeper is provided. Such as figure 1 with figure 2 As shown, a backing plate for a cushioned sleeper in this embodiment includes a plate-shaped body (such as a plate-shaped body 1) used to fit the pad on the lower surface of the sleeper. There are multiple rows of hemispherical grooves (such as hemispherical groove 2), and the lower surface of the plate-shaped body is provided with multiple rows of hemispherical grooves that are alternately spaced and arranged in dislocation with multiple rows of hemispherical grooves; each row The hemispherical grooves include a pluralit...

Abstract

The invention discloses a base plate for backing a sleeper. The base plate comprises a plate body which is in matched cushioning at the lower surface of the sleeper, wherein a plurality of arrays of semi-spherical grooves are formed sparsely and densely on the upper surface of the plate body at interval, and a plurality of arrays of semi-spherical grooves are formed sparsely and densely on the lower surface of the plate body at interval and are staggered with the plurality of arrays of semi-spherical grooves; each array of semi-spherical grooves comprises a plurality of semi-spherical grooves which are uniformly distributed at interval; and the plate body is a rectangular plate body, and all the vertex angles of the rectangular plate body are arc chamfers. The base plate for backing the sleeper can be used for overcoming the defects of poor damping effect, uneven stress dispersing, short service life, poor energy-saving and environmental-friendly performances and the like in the prior art, and has the advantages of good damping effect, uniform stress dispersing, long service life and good energy-saving and environmental-friendly performances.

Description

technical field [0001] The invention relates to the technical field of railway accessories, in particular to a backing plate for a cushioned sleeper. Background technique [0002] Generally, in sleeper structures such as railways, high-speed railways, and urban sleeper traffic, it is generally necessary to use elastic backing plates between sleepers (such as steel rails or rails) and sleepers to absorb the vibration energy generated when vehicles pass by and weaken the vibration belt. Incoming noise pollution, and to a certain extent, protect sleepers. [0003] However, most of the above-mentioned elastic backing plates are rubber plates, which are greatly affected by temperature, have poor protection effect on sleepers, have short service life, and are inconvenient to recycle. If the thermoplastic elastic material is used to make the elastic backing plate, although the defect that the rubber plate is greatly affected by temperature can be overcome, because the groove of th...
