Description
Technical field:
The utility model belongs to the cushion technique field, is specifically related to rubber shock-absorbing fastener under a kind of high ferro Line for Passenger Transportation rail.
Background technology:
The modern railways operational mode is a basic model with high speed, high density, and this pattern needs railway that good stable and rational circuit elasticity are provided, and possesses the characteristics of few maintenance.Therefore, the railway basis is developed to rigidization, and rail develops to heavy-duty, and this trend requires circuit that better elasticity is provided.And the circuit elasticity of necessity then is to alleviate rail abrasion, keeps circuit stable, and to adapt to high-speed, the highdensity requirement of vehicle, buffering wheel track stress keeps the joint level, and prolongation component life institute is necessary.
Rubber tie plate under rail is most important parts in the elastic rail fastener, and it is being undertaken and is slowing down from many functions such as rail vibration, mitigation wheel-rail impact, the effect of dispersion wheel load, prevention rail creeping, increase track insulations.In addition, rubber tie plate under rail is again directly to bear the power actuated parts of train load under rail, and load all is delivered on the sub rail foundation structure via rubber pad placed under-neath rail, directly influences its duty.From the geomery of rubber pad placed under-neath rail, it is to use the parts that condition is the harshest, deterioration is the fiercest in each component parts of track.
Traditional rubber mat plate is generally all carried out the industry standard TB/T2626-1995 of the Ministry of Railways, and it is adapted to the existing common railway that design speed is 120km/h, is difficult to satisfy the train requirement that speed per hour is higher than 350Km/h.Simultaneously present rail track is because load, and the quiet rigidity that needs rubber mat plate sometimes needs quiet rigidity a little bit smaller more again, in case and after traditional rubber mat plate shape determines, may not adjust quiet rigidity as required.Also just can not guarantee the steady and safety of bullet train.
The utility model content:
The purpose of this utility model provides rubber shock-absorbing fastener under a kind of high ferro Line for Passenger Transportation rail, and it can adjust the rubber shock-absorbing product of quiet rigidity and sound ratio of rigidity automatically, can solve the needs of the stability and safety under the situation of present train speed raising.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is made up of rubber mat plate and buffer insulation rubber and plastic backing plate, and rubber mat plate is arranged on the buffer insulation rubber and plastic backing plate.
The upper and lower surface of described rubber mat plate evenly is provided with several grooves, and groove is symmetrically distributed with the center on the upper and lower surface of backing plate, and staggers mutually, is provided with little groove in the soffit both sides of rubber mat plate.
Described buffer insulation rubber and plastic backing plate periphery is provided with several U type grooves, and the upper and lower surface of buffer insulation rubber and plastic backing plate is provided with decorative pattern, the decorative pattern internal corrosion dermatoglyph.
During installation, rubber mat plate is arranged on the centre position of fastener iron chair, and buffer insulation rubber and plastic backing plate is arranged on below the iron chair, by being bolted on the casing.Upper surface is directly with the rail contact, in order to regulate quiet rigidity and dynamic stiffness and durability, because the kinetic energy that raising produced and the momentum of train speed are bigger, increased buffer insulation rubber and plastic backing plate under rubber mat plate and iron chair, the decorative pattern of its upper and lower surface also plays the anti-skidding effect of track except the decay of playing vibration.
The utility model can be adjusted the rubber shock-absorbing product of quiet rigidity and sound ratio of rigidity automatically, can solve the needs of the stability and safety under the situation of present train speed raising.

Fig. 2 is the vertical view of Fig. 1,
Fig. 3 is the structural representation of edge buffering rubber and plastic backing plate 2 in the utility model,
Fig. 4 is the vertical view of Fig. 3,
Fig. 5 is that the A-A of Fig. 4 is to sectional view.
The specific embodiment:
With reference to Fig. 1-5, this specific embodiment by the following technical solutions: it is made up of rubber mat plate 1 and buffer insulation rubber and plastic backing plate 2, and rubber mat plate 1 is arranged on the buffer insulation rubber and plastic backing plate 2.
The upper and lower surface of described rubber mat plate 1 evenly is provided with several trapezoidal grooves 1-2, and trapezoidal groove 1-2 is symmetrically distributed with the center on the upper and lower surface of backing plate, and staggers mutually, is provided with less trapezoidal groove 1-1 in the soffit both sides of rubber mat plate 1.
Described trapezoidal groove 1-2 can be square or other similar geometric.
Described buffer insulation rubber and plastic backing plate 2 peripheries are provided with several U type grooves 2-1, and the upper and lower surface of buffer insulation rubber and plastic backing plate 2 is provided with decorative pattern 2-2, decorative pattern 2-2 internal corrosion dermatoglyph.
During installation, rubber mat plate 1 is arranged on the centre position of fastener iron chair, and buffer insulation rubber and plastic backing plate 2 is arranged on below the iron chair, by being bolted on the casing.Upper surface is directly with the rail contact, in order to regulate quiet rigidity and dynamic stiffness and durability, because the kinetic energy that raising produced and the momentum of train speed are bigger, increased buffer insulation rubber and plastic backing plate 2 under rubber mat plate 1 and iron chair, the decorative pattern 2-2 of its upper and lower surface also plays the anti-skidding effect of track except the decay of playing vibration.
This specific embodiment has following feature:
1, groove is set on rubber mat plate, helps the adjusting of the adjusting of quiet rigidity, particularly dynamic stiffness, kinetic energy and momentum are bigger in the train high-speed cruising, and the frequency of vibrations is higher, and this just needs the good product of high performance dynamic stiffness;
2, by the groove of different size is set on the plate body external surface of rubber mat plate, can realize that load according to different decides the size of bearing area, thereby automatically the quiet rigidity of rubber mat plate is adjusted, require quiet rigidity little in the time of can satisfying train operation like this, guarantee the requirement of good damping effect, require quiet rigidity to beat in the time of satisfying train operation again, guarantee the requirement of the safety of train operation.
3, when having increased rubber mat plate, under rubber mat plate and iron chair, increased buffer insulation rubber and plastic backing plate, help increasing the quiet rigidity and the dynamic stiffness of track, just when momentum and impact were big, damping effect was better.Increase buffer point plate elasticity and the elasticity retentivity all is better than the standard rubbers backing plate, can improve uniformity, stability, durability and the safety of track, more effectively reduced the vibratory response of railway roadbed.Simultaneously also reduce maintenance load, also can adapt to the needs of train speed raising development.
4, under rubber mat plate and iron chair, increase buffer insulation rubber and plastic backing plate and have better electrical insulating property, help the transmission of signal in the high-speed track, and the protection of electric current is also played a role than traditional rubber mat plate.
