Description
Technical field
The utility model relates to a kind of track traffic and uses fastener, particularly relates to a kind of general location of vibration damping requirement of compatibly rolling off the production line and uses fastener.
Background technology
In the track traffic design object, the rail system design is an important component part, also is one of track traffic core technology.The present domestic fastener that generally adopts the general vibration damping section of underground cable 60kg/m rail, this fastener will satisfy the requirement of the fastener amount of heightening, gauge adjustment amount and buckle press, mainly is divided into ω type elastic bar fastener and e type elastic bar fastener according to the spring pattern.But above-mentioned fastener also exists deficiency, and adopting like ω type elastic bar fastener has the bolt spring, and when train passed through, bolt was prone to loosening, increased the maintenance workload; Though e type elastic bar fastener has adopted the non-bolt spring, spring afterbody circular arc is less than normal, and rail is to the reaction force of spring when big slightly, spring frangible and slippage, and the application life of spring is short, and iron chair is thicker simultaneously, has increased the height and the weight of fastener.
Summary of the invention
The utility model technical problem to be solved is, overcomes the shortcoming of prior art, and a kind of spring not frangible and slippage are provided, and is easy for installation, improves comfort level by bus, and the underground cable vibration damping requires general location to use fastener.
The technical scheme that the utility model adopted is: fastener is used in a kind of track traffic, comprises iron chair, anchor bolt, spring, nylon sleeve, Insulation rail distance keeper, rubber tie plate under rail, rubber mat plate and spring washer; Said nylon sleeve is embedded in the sleeper, on said iron chair and rubber mat plate, is formed with the anchor bolt through hole respectively, and said anchor bolt passes spring washer, iron chair and rubber mat plate respectively in regular turn and screws in the nylon sleeve; Place, said iron chair diagonal angle is provided with the iron seat, is formed with the jack that penetrates limb in the spring on the said iron seat, and said jack is a Long Circle.
The heel end of said spring is a curved surface.
Said Insulation rail distance keeper facade A is 34-36mm.
Also include height adjusting cushion plate, said height adjusting cushion plate is arranged between rubber mat plate and the iron chair; Between said Insulation rail distance keeper, be provided with rubber tie plate under rail.
Said anchor bolt is integrally formed by bolt and plain washer.
The thickness of said rubber mat plate is 15-17mm, and the rubber mat plate upper and lower faces all is formed with lateral trench.
The beneficial effect of the utility model is: this fastener possesses the functional requirement of urban track traffic fastener, and is simple in structure, dependable performance, and highly versatile is applicable in newly-built track traffic projects, can be applied to existing track remodelling engineering simultaneously.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain:
To shown in Figure 8, fastener is used in the utility model track traffic, comprises iron chair 1, anchor bolt 2, spring 3, nylon sleeve 4, Insulation rail distance keeper 5, rubber tie plate under rail 6, rubber mat plate 7, height adjusting cushion plate 8 and spring washer 9 like Fig. 1; Said nylon sleeve 4 is embedded in the sleeper, on said iron chair 1 and rubber mat plate 7, is formed with the anchor bolt through hole respectively, and said anchor bolt 2 passes spring washer 9, iron chair 1 and rubber mat plate 7 respectively in regular turn and screws in the nylon sleeves 4; One deck or which floor height adjusting cushion plate 8 add when in work progress, needing, can heighten whole height, and this height adjusting cushion plate 8 is arranged between rubber mat plate 7 and the iron chair 1; Between said Insulation rail distance keeper 5, be provided with rubber tie plate under rail 6; Place, said iron chair 1 diagonal angle is provided with iron seat 11; Be formed with the jack 12 that penetrates limb in the spring 3 on the said iron seat 11, toe-end is withheld on track gauge block, and heel end is withheld on the iron chair jack base; Said jack 12 is a Long Circle; Slotted hole can make the more convenient installation of spring, when driving, can not impact limb activity in the spring.In addition, the iron chair reduced thickness can alleviate fastener weight, reduces height, increase stability; Spring 3 is improvement that existing e shape spring is carried out, and particularly the spring heel end is bent processing, promptly; The heel end 31 of spring 3 is a curved surface; Curved surface has increased the elasticity of withholding the position with iron chair, increases spring bullet journey thereby can reach, and reduces the effect of inner equivalent stress; Make spring be not easy to fracture and slippage, prolong the application life of spring.The integrative-structure that said anchor bolt 2 is made up of bolt and plain washer can increase stability, and reduces the part of assembling.Said rubber mat plate 7, its thickness is 15-17mm, conventional thickness is 14mm in the prior art, because the increase of plate thickness makes the also corresponding increase of its elasticity; In addition, all be formed with lateral trench 71 at rubber mat plate 7 upper and lower faces, groove can prevent that sealing gets into sleeve pipe, increases comfort level by bus.Rubber tie plate under rail has excellent elasticity and supporting capacity; The application of rubber mat plate has effectively increased the elasticity of track structure; Reduce the dynamic stress of track structure and the load power of railway roadbed; Thereby minimizing wheel and vibrations and noise that rail interaction produces to reducing the life-span of circuit disease and prolongation locomotive corresponding component, have irreplaceability.The thickening of track gauge block facade, facade A is 34-36mm, best facade A is 35mm; The facade of track gauge block routine is 33mm in the prior art, and the facade of this novel thickening can reduce the impact force to the rail support groove shoulder block, and insulation effect is better; Two ends are provided with the slope; Spring is easy mounting more, and track gauge block and iron chair shoulder block fit clearance are little, prevents the longitudinal leap of track gauge block and spring.
The utility model possesses the functional requirement of urban track traffic fastener, can be applied in newly-built track traffic projects, can be applied in the existing line improvement project simultaneously.
