Abstract
The utility model discloses a high-intensity elastic backing board under a rail. The high-intensity elastic backing board under the rail comprises a backing board body made of elastic materials, the backing board body is flat-board-shaped, flanges are arranged at the two sides of the backing board body, the upper surface and the lower surface of the backing board body are smooth, and a plurality of damping holes are formed inside the backing board body. The high-intensity elastic backing board under the rail has the advantages that due to the fact that the damping holes are formed inside the backing board body, external dust can be prevented from entering the backing board body, and damage to the backing board under the rail is reduced. After the high-intensity elastic backing board under the rail is used for many years, the high-intensity elastic backing board under the rail still has a good damping effect and is long in service life. By means of structure, the high-intensity elastic backing board under the rail enables passengers in a train to be comfortable.
Description
Technical field
The utility model relates to a kind of railway rail pad, especially relates to resilient sleeper-bearing under a kind of high strength rail.
Background technology
Rail is erected at solid concrete roabed or cement sleeper top, between rail and solid concrete roabed or cement sleeper railway rail pad is installed.The effect of railway rail pad: when train process rail, play the effect of bumper and absorbing shock, reduce the damage that causes because of vibrations between rail and solid concrete roabed or the cement sleeper.Traditional railway rail pad is made by elastomeric material, and railway rail pad becomes tabular substantially, and flat upper plane and lower plane are respectively arranged with groove, and the groove on the upper lower plane is interspersed, and the trend of groove is identical with the bearing of trend of rail; Arranging of groove can improve buffering and damping effect further.There are the following problems for present railway rail pad: groove is arranged on flat upper lower plane, after using all the year round, can long-pendingly expire dust on the groove, and it not only can affect the damping effect of railway rail pad; Also can reduce the life-span of railway rail pad.
Summary of the invention
Technical problem to be solved in the utility model provides resilient sleeper-bearing under the high strength rail of a kind of good damping effect, long service life.
The utility model solves the problems of the technologies described above the technical scheme that adopts: resilient sleeper-bearing under a kind of high strength rail, comprise the backing plate body that elastomeric material is made, described backing plate body becomes tabular, the both sides of described backing plate body are provided with rib, the upper and lower surface that it is characterized in that described backing plate body is smooth, and the inside of described backing plate body arranges many shock relieve vents.
Many shock relieve vents are evenly arranged in the inside of backing plate body.
Described shock relieve vent is arranged on the centre of backing plate body.
The bearing of trend of described shock relieve vent is identical with the extension aspect of rail.
The bearing of trend of described shock relieve vent is vertical with the extension aspect of rail.
Described shock relieve vent is circular hole.
Described shock relieve vent is elliptical aperture.
The backing plate body is made by polyurethane material.Has preferably damping effect.
The closed at both ends of shock relieve vent.Prevent that external dust from entering in the shock relieve vent.
Shock relieve vent is through hole.
Compared with prior art, the utility model has the advantages that shock relieve vent is arranged on the inside of backing plate body, can prevent that external dust from entering, reduce the damage of railway rail pad; After using all the year round, still keep good damping effect and long application life.The structure of this railway rail pad makes the passenger in the train have good comfortableness.

The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Embodiment one: resilient sleeper-bearing under a kind of high strength rail, comprise the backing plate body 1 that elastomeric material is made, 1 one-tenth tabular of backing plate body, the both sides of backing plate body 1 are provided with rib 2, the upper and lower surface of backing plate body 1 is smooth, the inside of backing plate body 1 arranges many shock relieve vents 3, many shock relieve vents 3 are evenly arranged in the inside of backing plate body 1, shock relieve vent 3 is arranged on the centre of backing plate body 1, the bearing of trend of shock relieve vent 3 is identical with the extension aspect of rail, shock relieve vent 3 is circular hole, and backing plate body 1 is made the closed at both ends of shock relieve vent 3 by polyurethane material.
Embodiment two: other structures are identical with embodiment one, and the bearing of trend of difference shock relieve vent 3 is vertical with the extension aspect of rail, and shock relieve vent 3 is elliptical aperture, and shock relieve vent 3 is through hole.
