The high-speed railway ballast track steel rail fastener system comprises screw spikes (30), elastic strips (31), track gauge baffle plates (32), pre-embedded sleeves (12) and under-track elastic sleeper plates (21), wherein the track gauge baffle plates (32) are arranged out of two sides at the lower edge of the UIC60 steel rail (20) in a rail supporting groove (11) of the pre-stressed concrete sleeper (10), the screw spikes (30) are detachably connected with the pre-embedded sleeves (12) which are fixedly arranged in the pre-stressed concrete sleeper (10) by penetrating through the track gauge baffle plates (32), the elastic strips (31) are tightly pressed on the track gauge baffle plates (32) and the lower structure of the UIC steel rails (20), and axial lines of the screw spikes (30) and the pre-embedded sleeves (12) are vertical to the bottom surface of the rail supporting groove (11) of the pre-stressed concrete sleeper (10).
Description
Technical field
The utility model relates to railway, a kind of especially high-speed railway Ballast track rail fastener system.
Background technology
Rail fastening is in order to connect the component of rail and sleeper (or other types sub rail foundation) on track, claim again intermediate fastening, its effect is that rail is fixed on sleeper rail support groove, keeps gauge and stops the vertical transverse shifting of rail with respect to sleeper.Fastener should be able to keep the reliable connection of rail and sleeper for a long time, effectively, and can under dynamic action, give full play to its bumper and absorbing shock performance, delays track residual deformation accumulation.Also answer simple structure, be convenient to install and dismounting.Rail fastening mainly comprises the parts such as screw spike, railway rail pad and elastic buckles casting die, the design of fastener system is the type of rail and sleeper fully, different rail and sleeper type, because its structure design size differs, especially during the Rails In Foreign Countries type such as supporting UIC60 of China's principal mode concrete sleeper, existing fastener system will no longer be applicable to connect UIC60 rail and China's principal mode concrete sleeper.
In Railway Market, in most Ballast track rail fastener system, the axis of screw spike and service sleeve is with respect to rail support groove inclined bottom surface certain angle on post stressed concrete sleeper in overseas.And China's sleeper adopts pre-tensioning system prefabricated, demoulding difficulty while producing sleeper in order to reduce, China's sleeper requires fastener service sleeve and sleeper rail support groove to keep vertical, this is unfavorable for the outlet of China's sleeper and high speed railway track technology, in order to keep the versatility of overseas rail fastener system parts, need to develop a kind of Novel fastener to connect UIC60 rail and China's principal mode sleeper.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high-speed railway Ballast track rail fastener system, to connect UIC60 rail and China's principal mode prestressed reinforced concrete tie.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
High-speed railway Ballast track rail fastener system of the present utility model, comprise resilient sleeper-bearing under screw spike, spring, gauge apron, service sleeve, rail, gauge apron is arranged at outside UIC60 rail lower edge both sides in prestressed reinforced concrete tie rail support groove, screw spike removably connects through gauge apron and the service sleeve being fixed in prestressed reinforced concrete tie, and spring is pressed in the substructure of gauge apron and UIC60 rail, it is characterized in that: the axis of described screw spike, service sleeve is perpendicular to the bottom surface of prestressed reinforced concrete tie rail support groove.
The beneficial effects of the utility model are, screw spike, sleeve pipe are vertical with prefabricated sleeper, the prefabricated convenience of sleeper, and the easily demoulding, avoids sleeper cracking.Screw spike is withheld spring, stressed more reasonable; With respect to China's principal mode fastener system, i.e. II type fastener, track gauge block and gauge apron, be combined into parts, simple in structure, and maintenance is convenient; Can connect well China's principal mode sleeper and UIC60 rail, can keep good versatility with external conventional fastener system again.
Accompanying drawing explanation

Component shown in figure, toponym and corresponding mark: resilient sleeper-bearing 21, screw spike 30, spring 31, gauge apron 32, stopper slot 32a, spacing convex shoulder 32b under prestressed reinforced concrete tie 10, rail support groove 11, service sleeve 12, UIC60 rail 20, rail.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
See figures.1.and.2, high-speed railway Ballast track rail fastener system of the present utility model comprises resilient sleeper-bearing 21 under screw spike 30, spring 31, gauge apron 32, service sleeve 12, rail, gauge apron 32 is arranged at outside UIC60 rail 20 lower edge both sides in prestressed reinforced concrete tie 10 rail support grooves 11, screw spike 30 removably connects through gauge apron 32 and the service sleeve 12 being fixed in prestressed reinforced concrete tie 10, and spring 31 is pressed in the substructure of gauge apron 32 and UIC60 rail 20.The axis of described screw spike 30, service sleeve 12 is perpendicular to the bottom surface of prestressed reinforced concrete tie 10 rail support grooves 11., the prefabricated convenience of screw thread prestressed reinforced concrete tie, the easily demoulding, avoids sleeper cracking.Screw spike 30 springs 31, stressed more reasonable, with respect to China's principal mode fastener system, be II type fastener, track gauge block and gauge apron, be combined into parts, simple in structure, maintenance is convenient, can connect well China's principal mode sleeper and UIC60 rail, can keep good versatility with external conventional fastener system again.
With reference to the outside of gauge apron 32 described in Fig. 1 and Fig. 3, there is the stopper slot 32a of restriction spring 31 outside compression point transverse shiftings, inner side has the spacing convex shoulder 32b of restriction spring 31 inner side compression point vertical direction depression distance, make the installation of profile system more easy, installation quality is more easily guaranteed.With reference to Fig. 1, between the bottom surface of described rail 20 and the bottom surface of rail support groove 11, resilient sleeper-bearing 21 under rail is set.
Some principles of the above the utility model high-speed railway Ballast track rail fastener system that just explains through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore the corresponding modify being likely utilized every and equivalent, all belong to the scope of the claims that the utility model is applied for.
