Description
technical field
The utility model relates to a kind of railway shock absorber, especially relates to the Ballast track damping elastomer backing plate that a kind of high speed railway is used.
Background technology
Railway track structure can be divided into two classes on the whole: ballast bed, the sleeper of take is basic Ballast track; Take concrete or bituminous mixture as basic non-fragment orbit.Traditional Ballast track adopts rubble railway ballast as railway roadbed, the features such as increasing bullet vibration damping, row water and convenient for maintaining maintenance because of stone tiny fragments of stone, coal, etc. railway roadbed, Ballast track there is lay the advantages such as convenient, cost is low, easy maintenance, for a long time as the primary structure form of the general railroad track in countries in the world.
In recent years along with the raising of socioeconomic development and scientific and technological level, there is being significant progress in China aspect the high speed of railway transportation and city underground, light rail transit; But the development characteristic due to China, along with increasing of railway speed increase and densely populated metropolis elevated railway station and viaduct, the vibration and acoustics that train causes has also caused the public's extensive concern to the impact of environment and human health, so vibration and noise reducing becomes subject matter.In Ballast track bottom, laying railway ballast resilient sleeper-bearing, to reduce basic vibration be one of effective measures of vibration and noise reducing, and this scheme fully approved on high-speed railway abroad, but at home also in the starting stage.
In the building railway of existing routine, generally with yielding rubber backing plate under rail, come vibration damping and noise reduction, but this rubber mat plate can not be preferably matches with the railway of high speed operation, cannot solve preferably rail vibrations and noise problem under high speed.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of damping effect good, Ballast track damping elastomer backing plate is easily located in installation, and rail vibrations and noise problem that it can solve in high-speed railway, improve the application life of railway and reduce fault rate.
The purpose of this utility model is achieved in that
A kind of Ballast track damping elastomer backing plate, it comprises backing plate body, described backing plate body front parallel longitudinal is provided with multiple row projection, at backing plate body interior parallel longitudinal, multiple row rhombus hole is set, in backing plate body arranged on left and right sides, joint is set, and described projection, rhombus hole, joint and backing plate body are arranged to an overall structure, the center of described projection is on the shorter cornerwise extension line in diamond hole hole.
The width of projection be 8-12mm all can, preferred 9mm; The height of projection be 2-5mm all can, preferred 3mm; Distance between adjacent two row projections be 8-12mm all can, be preferably 9mm; Described hole is rhombus, the distance of the length of side of rhombus hole between being be 8-12mm all can, be preferably 9mm; The larger interior angle of rhombus hole be 100-140 ° all can, be preferably 120 °; The whole height of elastic layer be 18-26mm all can, be preferably 22mm.
Described backing plate is made by elastomeric material.
Compared with prior art, the beneficial effects of the utility model are:
The projection in damping elastomer backing plate front and inner rhombus hole play damping effect; The projection in damping elastomer bed course front can be disperseed to support top and be conducted the load that gets off, cushions, thereby have excellent damping property and interior diamond hole can produce certain deformation.And due to the gap between each row projection, water or other liquid can be smoothly through this elastic damping layer and utilize and remove and flow such as row water systems such as row water pipes, thereby can not infiltrate into damping elastomer backing plate below, do not affect its functional performance.
The utility model Ballast track damping elastomer backing plate, damping effect is good, location is installed and facilitates it can solve rail vibrations and the noise problem in high-speed railway, improves the application life of railway and reduces fault rate.
Accompanying drawing explanation
Fig. 1 is the cross-sectional structure schematic diagram of damping elastomer backing plate for the utility model Ballast track.
Wherein:
Backing plate body 1, projection 2, rhombus hole 3, joint 4.
The specific embodiment
Referring to Fig. 1, a kind of Ballast track damping elastomer backing plate that the utility model relates to, it comprises backing plate body 1, described backing plate body 1 front parallel longitudinal is provided with multiple row projection 2, at the inner parallel longitudinal of backing plate body 1, multiple row rhombus hole 3 is set, in backing plate body 1 arranged on left and right sides, joint 4 is set, and described protruding 2, rhombus hole 3, joint 4 be arranged to an overall structure with backing plate body 1, described protruding 2 center is on the shorter cornerwise extension line in diamond hole hole 3.
Can, according to different road conditions and requirement, can design projection and the rhombus hole of size, different number, different size at regular intervals; The width of projection be 8-12mm all can, preferred 9mm; The height of projection be 2-5mm all can, preferred 3mm; Distance between adjacent two row projections be 8-12mm all can, be preferably 9mm; Described hole is rhombus, the distance of the length of side of rhombus hole between being be 8-12mm all can, be preferably 9mm; The larger interior angle of rhombus hole be 100-140 ° all can, be preferably 120 °; The whole height of elastic layer be 18-26mm all can, be preferably 22mm.
Described backing plate is made by elastomeric material.
This novel Ballast track that relates to is mounted under rail and uses with damping elastomer backing plate, is laid on bottom and the both sides of railway ballast, forms elastic damping layer; It can reduce structural vibration effectively.The projection in damping elastomer backing plate front and inner rhombus hole play damping effect; The projection in damping elastomer bed course front can be disperseed to support top and be conducted the load that gets off, cushions, thereby have excellent damping property and interior diamond hole can produce certain deformation.And due to the gap between each row projection, water or other liquid can be smoothly through this elastic damping layer and utilize and remove and flow such as row water systems such as row water pipes, thereby can not infiltrate into damping elastomer backing plate below, do not affect its functional performance.
Aspect material, this damping elastomer bed course can adopt many general rubber to make, and is preferably high-grade native rubber composite material.
Damping elastomer bed course of the present utility model also can be applicable to the basal layers such as high-speed railway, urban light rail, subway, bridge, tunnel and highway, can effectively alleviate structural vibration, thereby extend the application life of agent structure, reduce maintenance cost and improve safety in utilization.Different by projection and the physical dimension of rhombus hole, can obviously reduce the noise and vibration that train produces under the different speeds of service, the stability that raising vehicle is in operation; Between its gap, there are good ventilation and the effect of row water simultaneously, make elastic layer bottom not have deposit.
