Abstract
The utility model provides a railway elastic base plate which is a planar base plate; and a bearing surface of the planar base plate is provided with bosses which are uniformly distributed. The railway elastic base plate redesigns the original pure-plate structure into a structure form with the bearing surface of being a cylindrical boss, a blocky boss and a strip boss, and the bosses are uniformly distributed so as to reduce the static stiffness of the base plate, thus not only solving the flatness of the base plate, but also guaranteeing the deformation problem of the product; therefore, the railway elastic base plate not only reduces the contact area of the base plate, but also leads the load to be distributed uniformly, reducing the static stiffness and saving the raw materials.
Description
(1) technical field
The utility model relates to a kind of railroad tie plate, is specifically related to a kind of railway spring backing plate.
(2) background technology
Along with the raising of railway operation speed, the damping performance of railway is also had higher requirement, all face this great challenge in the damping performance of rubber mat plate in the past and application life.Now, use a kind of porous elastic material to substitute in the past rubber mat plate, use this porous elastic material after, if continue to use the structure of traditional backing plate, can find that quiet rigidity is excessive, reduced the damping performance of backing plate.
(3) summary of the invention
The purpose of this utility model is to provide a kind of not only can satisfy every performance indications of railroad tie plate in the past, and has thoroughly solved the too high problem of quiet rigidity that occurs behind the utilization new material, has also saved raw-material railway spring backing plate simultaneously.
The purpose of this utility model is achieved in that the railway spring backing plate is the plane backing plate, and the bearing surface of plane backing plate is provided with projection, and projection evenly distributes.
The utility model also has some technical characterictics like this:
1, described projection is a cylindrical bump;
2, described projection is a block-shaped protrusion;
3, described projection is a strip projected parts;
4, the two ends of described plane backing plate are provided with connector.
It is cylindrical bump, block-shaped protrusion, strip projected parts form of structure that the utility model redesigns into bearing surface with original slate structure, boss evenly distributes, reduce the quiet rigidity of backing plate, both solve the flatness problem of backing plate, also guaranteed the problem on deformation of product, like this, both reduced the contact area of backing plate, load is evenly distributed, reduced quiet rigidity, also save raw material.
(4) description of drawings
Fig. 1 is the utility model railway spring backing structure schematic diagram, and Fig. 2 is the utility model side view.
(5) specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1, the utility model railway spring backing plate is the plane backing plate, and the bearing surface 1 of plane backing plate is provided with projection 2, and projection 2 evenly distributes.Projection 2 can be cylindrical bump, block-shaped protrusion or strip projected parts, and the two ends of plane backing plate are provided with connector 3.
Claims (5)
1. railway spring backing plate, the railway spring backing plate is the plane backing plate, it is characterized in that the bearing surface of plane backing plate is provided with projection, projection evenly distributes.
2. railway spring backing plate according to claim 1 is characterized in that described projection is a cylindrical bump.
3. railway spring backing plate according to claim 1 is characterized in that described projection is a block-shaped protrusion.
4. railway spring backing plate according to claim 1 is characterized in that described projection is a strip projected parts.
5. according to claim 1 or 2 or 3 or 4 described railway spring backing plates, it is characterized in that the two ends of described plane backing plate are provided with connector.
