[0004] However, in this backing plate, the protrusions on the upper and lower bearing surfaces of the backing plate are symmetrically arranged, so that the plate body between the adjacent protrusions on the upper surface or the lower surface of the backing plate is too thin, so that the backing plate is prone to damage during use. In case of fracture, its structure is unstable

Embodiment Construction
[0035] Such as Figure 1 to Figure 5 Shown, this rail backing plate, whole backing plate is integrally formed. The backing plate includes a rectangular plate body 1, and the left and right edges of the bottom surface of the plate body 1 have a raised bottom edge 2 perpendicular to the bottom surface, that is to say, the bottom edge 2 is located at the two wide sides of the plate body 1.
[0036] Four upper energy-absorbing units 3 that can absorb vibration energy are arranged on the top surface of the board body 1 along a direction perpendicular to the bottom edge 2, and three upper energy-absorbing units 3 that can absorb vibration energy are arranged on the bottom surface of the board body 1 along a direction perpendicular to the bottom edge 2. The lower energy-absorbing unit 4 is directly facing the gap between two adjacent upper energy-absorbing units 3 along the orthographic projection direction of the top surface of the board body 1 . That is to say, the upper energy-ab...

The invention relates to a rail backing plate, belongs to the technical field of railway parts, and solves the problem of instability in the structure of a conventional rail backing plate. The rail backing plate comprises a rectangular plate body, wherein a plurality of upper energy absorption units capable of absorbing vibration energy are arranged on the top surface of the plate body in a direction perpendicular to the bottom edge of the plate body, a plurality of lower energy absorbing units capable of absorbing vibration energy are arranged on the bottom surface of the plate body in a direction perpendicular to the bottom edge of the plate body, and in the orthographic projection direction of the top surface of the plate body, each lower energy absorbing unit directly faces to a clearance between two adjacent upper energy absorbing units. Compared with the prior art, the rail backing plate provided by the invention has the advantages that the upper energy absorption units and the lower energy absorption units on the backing plate are arranged in a staggered manner, so that the structure of the backing plate is more stable; each energy absorbing column is arranged to take the shape of a cone frustum, so as to enable the backing plate to play a better buffering effect on a train. Therefore, the train is enabled to run more stably. A deformation slot is formed in the top of each auxiliary energy absorbing column, the buffering effect of the backing plate on the train can be enhanced, and the static rigidity of the backing plate is reduced.
Description
technical field [0001] The invention belongs to the technical field of railway fittings and relates to a rail backing plate. Background technique [0002] The train is one of the main means of transportation for human beings, and its high speed and low accident rate are also favored by the majority of passengers. Rail is an essential infrastructure for train operation, and its quality directly affects the speed and safety of the train. In order to make the train run more smoothly and ensure the comfort of the passengers when riding the train, generally a backing plate will be provided under the rails to realize the shock absorption effect. [0003] For example, Chinese utility model patent (application number: 200920100124.1; authorized announcement number: CN 201459537 U) discloses a kind of railway elastic backing plate, the railway elastic backing plate is a flat backing plate, and the bearing surface of the flat backing plate is provided with protrusions, The bumps are...
