Abstract
The utility model provides a kind of elastic sleeper.Elastic sleeper comprises: sleeper body; Cushion, cushion is arranged on the soffit of sleeper body.Application the technical solution of the utility model, the soffit of sleeper body arranges cushion, effectively can reduce the vibration noise of railway.
Description
Technical field
The utility model relates to a kind of elastic sleeper.
Background technology
Along with the development of Railway Transport Industry expands, the requirement for track structure is also more and more higher, is not only embodied in circuit high stability, durability and reliability, also more urgent to the demand of track structure in road-ability, low vibratility etc.How the rigid foundation locations such as the bridge especially in Ballast track circuit and tunnel, reduce wheel-rail interaction, reduces track vibration noise, and stability and the maintenance cycle of improving railway roadbed become railroad track technical field important research direction.
Utility model content
The utility model aims to provide a kind of elastic sleeper reducing the vibration noise of railway.
To achieve these goals, the utility model provides a kind of elastic sleeper, and elastic sleeper comprises: sleeper body; Cushion, cushion is arranged on the soffit of sleeper body.
Further, the upper surface of sleeper body is provided with two rail support grooves, position relative with each rail support groove on the soffit of sleeper body arranges a cushion respectively.
Further, cushion is bonding with sleeper body.
Further, cushion on the surface of sleeper body, be provided with anti-skid structure.
Further, anti-skid structure is that corrugated is protruding.
Further, anti-skid structure is multiple projection, and multiple projection presses row-column arrangement.
Further, projection is any one or more in circle, rectangle, triangle and rhombus.
Further, the pillow middle section height 160mm ~ 210mm of elastic sleeper, the rail lower section height of elastic sleeper is 200mm ~ 250mm.
Further, the width of the soffit of elastic sleeper is 200mm ~ 320mm.
Application the technical solution of the utility model, elastic sleeper comprises sleeper body and cushion, and cushion is arranged on the soffit of sleeper body.Application the technical solution of the utility model, the soffit of sleeper body arranges cushion, effectively can reduce the vibration noise of railway.
Accompanying drawing explanation
The Figure of description forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 shows the structural representation of the elastic sleeper of the utility model embodiment;
Fig. 2 shows the plan structure schematic diagram of the elastic sleeper of the utility model embodiment;
What Fig. 3 showed the elastic sleeper of the utility model embodiment looks up structural representation;
Fig. 4 shows the side-looking structural representation of the elastic sleeper of the utility model embodiment.
Reference numeral: 1, sleeper body; 2, cushion; 3, reinforcing bar; 4, rail support groove.
Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figures 1 to 3, the elastic sleeper of the utility model embodiment comprises sleeper body 1 and cushion 2, and cushion 2 is arranged on the soffit of sleeper body 1.
The cushion 2 be arranged on the soffit of sleeper body 1 can alleviate train vibratory impulse to infrastructure in running effectively, effectively reduces railroad noise.
As shown in Figure 4, in sleeper body 1, be configured with the prestressed reinforcement 3 that many diameter of phi are 7.0mm, come, to elastic sleeper Shi Hanzhang, to meet supporting capacity requirement with this.
Cushion 2 is bonding with sleeper body 1.Cushion 2 is bonded on sleeper body 1, can prevent from causing cushion 2 to depart from sleeper body 1 because of the vibration of producing in train travelling process, effectively improves practicality and the reliability of elastic sleeper.
The upper surface of sleeper body 1 is provided with two rail support grooves 4, position relative with rail support groove 4 on the soffit of sleeper body 1 arranges a cushion 2 respectively.
Rail support groove 4 is for installing rail, and the power that rail support groove 4 place bears in the process of train operation is maximum, and cushion 2 is arranged on the position relative with rail support groove 4, is conducive to alleviating train in running to the vibratory impulse of infrastructure.
Cushion 2 on the surface of sleeper body 1, be provided with anti-skid structure.Anti-skid structure improves the friction between elastic sleeper and railway ballast effectively, prevents elastic sleeper from moving.
In the present embodiment, anti-skid structure is that corrugated is protruding.
Can also preferably, anti-skid structure is multiple projection, and multiple projection presses row-column arrangement.Projection is any one or more in circle, rectangle, triangle and rhombus.
In the present embodiment, the pillow middle section height 160mm ~ 210mm of elastic sleeper, the rail lower section height of elastic sleeper is 200mm ~ 250mm.The width of the soffit of elastic sleeper is 200mm ~ 320mm.
Rail lower section height is the height in the cross section at rail support groove 4 place perpendicular to the bearing of trend of elastic sleeper.
Elastic sleeper comprises in the pillow of the sleeper middle part between two rail support grooves 4, and pillow middle section height is the height in the cross section located in the pillow perpendicular to the bearing of trend of elastic sleeper.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
