Abstract

The utility model provides a damping rubber base plate which comprises a rubber plate 1. The damping rubber base plate is characterized in that the upper surface of the rubber plate 1 is glued with a corrosion resistant plate 2, and arc grooves 3 with the semidiameter of 50mm are arranged at the lower surface of the rubber plate 1 at intervals of 50mm. The damping rubber base plate integrally glues the rubber plate with the corrosion resistant plate, so that the high-speed vibration and the impacting extruding force when a vehicle passes through a steel rail can be buffered, and a roadbed and a railroad tie of the steel rail can be protected; and the arc grooves with the semidiameter of 50mm are arranged at the bottom of each damping rubber base plate at intervals of 50mm, so that the water exhausting performance and the insulating performance are good, and a certain deformation space is available when a load is applied to the plate. Therefore, the damping rubber base plate is small in abrasion, hard to fall off, and longer in service life.

Description

The vibration isolation rubber backing plate

Technical field

The utility model relates to a kind of rubber mat plate, specifically is a kind of vibration isolation rubber backing plate that is used on the rail.

Background technology

Along with the raising of train speed, more and more higher to the technical requirements of track structure, compare with ballasted track, ballastless track has better overall, stability and durability, and in life cycle basic maintenance-free.No matter be ballasted track or ballastless track, rail mechanism all must be possessed certain elasticity, concerning ballasted track, the compactness of ballast aggregate and the particle diameter of ballast aggregate directly influence the elasticity of railway roadbed, plate-type slag-free orbit is for improving the elasticity of track, usually adopt and under the track plate, fill the CA mortar as resilient sleeper-bearing, but in some special locations, changeover portion as densely populated area or some road-bridges, bridge-tunnel etc., one deck rubber mat plate will be overlayed, with the elasticity of further increase slab track between CA mortar and track plate.The anti vibration track plate has been adopted at viaduct and some special locations in more external the Shinkansens, has pasted the certain thickness rubber mat plate of one deck in track plate bottom exactly, and by rigidity reasonable in design, the wheel track that is used to decay contacts the vibration that produces.The rubber mat plate rigidity of Cai Yonging is 4.1KN/mm the earliest, adopting rigidity afterwards successively is 6.4KN/mm, 2.4KN/mm resilient sleeper-bearing, its plate lower bolster is to adopt real core rubber to make, the realization of rubber mat plate rigidity is mainly finished by rational structure and prescription design, but in actual application, the prescription design control and the inaccuracy of rubber rubber mat plate rigidity, rail displacement when train is run at high speed simultaneously increases, cause rail and rubber mat plate resistance to increase, make and directly increase with the rubber mat plate wearing and tearing that concrete slab sleeper contacts with rail, very easily under rail, extrude, cause degumming phenomenon, influence traffic safety.Simultaneously, present widely used rubber mat plate bottom mostly is dull and stereotyped greatly, both has been unfavorable for draining, and himself deformation space is limited, and anti-pressure ability is relatively also poor.

The utility model content

In view of above-mentioned weak point, the purpose of this utility model is to provide a kind of anti-pressure ability strong, reduces wear the vibration isolation rubber backing plate of difficult drop-off between rail.

In order to achieve the above object, the utility model has adopted following technical scheme: a kind of vibration isolation rubber backing plate, and described rubber tile upper surface is bonded with corrosion resistant plate, and it is the arc groove of 50mm that described rubber tile soffit interval 50mm has a radius.

The beneficial effects of the utility model are: rubber tile and corrosion resistant plate are bonded as one, vibration at high speed that is produced in the time of can cushioning vehicle by rail and impact extruded power, protection rail roadbed and sleeper, simultaneously every vibration isolation rubber backing plate bottom interval 50mm has the arc groove of a R50mm, not only has been beneficial to draining and insulation but also the certain deformation space is arranged when bearing load; Make that the utility model wearing and tearing are little, difficult drop-off, longer service life.

The specific embodiment

Below we will be described further the utility model in conjunction with the accompanying drawings.

As shown in Figure 1, a kind of vibration isolation rubber backing plate comprises rubber tile 1, and rubber tile 1 upper surface is bonded with corrosion resistant plate 2, as shown in Figure 2, and the arc groove 3 that it is 50mm that rubber tile 1 soffit interval 50mm has a radius.

Claims

1. a vibration isolation rubber backing plate comprises rubber tile (1), it is characterized in that: described rubber tile (1) upper surface is bonded with corrosion resistant plate (2), and it is the arc groove of 50mm (3) that described rubber tile (1) soffit interval 50mm has a radius.
