Abstract

The utility model discloses a shock-absorption elastic backing plate. Irregular bodies are integrally formed on the upper and the lower surfaces of the main body and are evenly distributed on the upper and the lower surfaces of the main body. As the total deformation (rigidity) of the utility model depends on the number, depth and the overall thickness of a groove or lug, the utility model has the characteristics of large deformation at a low speed under the low load on the same backing plate and small deformation at a high speed under the heavy load and can sufficiently ensure the comfort level during the running of the track traffic at a lower speed and the reliability and the safety during the running of the track traffic at a high speed or under the heavy load.

Description

The damping resilient sleeper-bearing

Technical field

The utility model relates to a kind of backing plate, relates in particular to the damping resilient sleeper-bearing that uses on a kind of track traffic and the cargo berth loop wheel machine traveling steel rail.

Background technology

Resilient sleeper-bearing is not only and is used for keeping two rail distances on the same track to equate, and safety and signal system safety component in good condition, and because its elasticity, can reduce vibrations significantly, thereby kept roadbed/basis not to be subjected to the influence of bullet train or load, so it is significant at aspects such as track traffic and Freight Dock.The most number average of resilient sleeper-bearing of the prior art needs to provide screen resilience by compressive deformation.Because due to the viscous-elastic behaviour of rubber, tool elasticity is recovered to need the regular hour, so under the effect of bullet train dynamic force or under the effect of wharf crane heavy load, the elasticity of rubber mat plate itself can not be brought into play fully.And in long-term use, can produce permanent deformation because of creep, and then cause the loosening of anchor bolt, threaten the security of operation of train.Then must change when permanent deformation acquires a certain degree, this has just brought a large amount of inspections, adjustment and maintenance work to Rail Transit System.

The utility model content

The purpose of this utility model is to overcome the problems referred to above that existing resilient sleeper-bearing exists, a kind of damping resilient sleeper-bearing is provided, the utility model can make backing plate provide high screen resilience simultaneously by flexural deformations and compressive deformation, to reach best damping effect, make breaking and damaging reduction of sleeper, thereby reach the purpose that reduces noise and roadbed maintenance.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of damping resilient sleeper-bearing is characterized in that: the upper and lower faces at body is formed with irregular body, and described irregular body is evenly distributed on the upper and lower faces of body.

Described irregular body is a channel form, and the bottom land of channel form presents arc, is slyness with cell wall and joins.

Described irregular body is the projection shape, and is dislocatedly distributed on the above and below of body, and the protruding end of projection shape is slick and sly shape.

The employing the beneficial effects of the utility model are:

One, the size of the utility model total amount distortion is that rigidity can change by quantity, the depth and the general thickness of groove or projection shape, possessed and realized that on same backing plate in low load be to have bigger distortion under the low speed, very little characteristics of deflection again under heavy duty promptly at a high speed, comfortable in the time of can fully guaranteeing the track traffic low cruise and at a high speed or the stable and safety during heavy service.

Two, the utility model can reduce vibrations, reduces the maintenance of noise and roadbed, make sleeper break and damage reduces to less, have long application life

Three, the utility model is slyness with cell wall and joins because irregular body evenly distributes, and when irregular body is a channel form, the bottom land of channel form presents arc, and when irregular body is the projection shape, the protruding end of projection shape is slick and sly shape, and actual effect is better.

The specific embodiment

A kind of damping resilient sleeper-bearing is formed with irregular body 1 at the upper and lower faces of body 2, and described irregular body 1 is evenly distributed on the upper and lower faces of body 2.When irregular body 1 is channel form; on the above and below of body 2, be dislocatedly distributed; the bottom land of channel form presents arc; being slyness with cell wall joins; with the centrostigma that eliminates stress; variation by ditch groove depth, groove width and inter-alveolar distance can be made into the high resiliency backing plate of different quiet, dynamic stiffness, and that quiet/dynamic stiffenss ratio and damping effect and hardness can be protected is constant.When irregular body 1 is the projection shape, on the above and below of body 2, be dislocatedly distributed, the protruding end of projection shape is slick and sly shape, relies on the projection mutual dislocation of upper and lower faces and realizes damping.

The raw material that the utility model adopts is a kind of high-performance thermoplastic elastic body, and the special-purpose compound resin of making an uproar is inhaled in damping, can buy off-the-shelf from manufacturer.This practicality is newly just made predetermined shape with this material.The utility model places above-mentioned raw material on the device fabrication line, produces the backing plate of strip by calibrator.During use, carry out cutting as required and make suitable backing plate.

Above-described only is preferred implementation of the present utility model.Should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the principle of the invention; need not the technical characterictic that the process creative work just can be associated; can also make some modification and improvement; these variations obviously all should be considered as equivalent feature, still belong within the protection domain of the utility model patent.
