Abstract
The utility model relates to an shock absorbing steel rail fastener in plate type, comprising a rail-bearing plate(1), a frame base(3) and a rubber bearing structure(2); wherein, the rubber bearing structure(2) is arranged under the rail-bearing plate(1), while the rail-bearing plate(1) and the rubber bearing structure(2) are enclosed together by use of the frame base(3). Apart form enhancing high elasticity under the rail or the plate, the utility model has the beneficial effects that the fastener can effectively improve the work conditions of the fastener, reduce mutual effect of the rails, prolong service life of the fastener, advance the stability and security of the train running and decrease the protection and maintenance of the rail structure, thereby having an extensive application prospect.
Description
Technical field
The utility model relates to the track in a kind of traffic technique field, relates in particular to the rail fastening in this track.
Background technology
Rail fastening is the vitals that connects rail and sub rail foundation, is made up of buckling piece, rail underlayer and coupling bolt.For keeping the track structure good technical performance, rail fastening should have sufficient intensity, certain buckle press, necessary elasticity and corresponding tunability.As to bigger sub rail foundations of rigidity such as PC sleeper and ballastless tracks, require railway rail pad to have higher elasticity; The steep gradient location then requires fastener that big longitudinal resistance can be provided, and prevents rail creeping; And the viaduct ballastless track is owing to lay gapless track, requires the toe load of fastening should not be too big, with the interaction force between control bridge floor and rail, prevents that longitudinal force that the gapless track long rail string produces is to the excessive transmission of bridge.Therefore, rail fastening has reflected the track structure main technical characteristics, is one of important step that keeps rigidity of track panel and its maintenance workload of decision.
The Shanghai rail transit Brilliant Pearl Line adopts viaduct ballastless track structural shape and lays gapless track, still belongs to the first in urban rail transit in China.The viaduct ballastless track is laid gapless track has specific (special) requirements to rail fastening, according to China's practical situation and at requirement of engineering, has developed the spring secures rail to sleeper that is suitable for the use of viaduct ballastless track.Find according to operation for many years, present employed aerial conveyor is loosening for guaranteeing that fastener is difficult for, and adopts very big nut torque to tighten anchor bolt, causes that height adjusting cushion plate can't provide elasticity under the plate, make that the fastener integral, flexible is relatively poor, weakened fastener vibration and noise reducing ability to a certain extent.
How overcoming above-mentioned defective is the problem that engineers and technicians will solve.
Summary of the invention
The utility model technical issues that need to address have provided a kind of plate-type vibration reducing rail buckle, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: the support rail plate; Also comprise: frame base, rubber bearing structure; Described rubber bearing structure is placed under the support rail plate, and frame base is trapped among support rail plate and rubber bearing structure together.
Compared with prior art, the beneficial effects of the utility model are: can all can provide higher elasticity under rail with under the plate, can not only effectively improve the fastener condition of work, reduce wheel-rail interaction, can also prolong fastener application life, improve the stationarity of train operation and safety, minimizing track structure maintenance, have broad application prospects.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 uses connection assembly drawing of the present utility model;
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As seen from Figure 1: the utility model comprises: support rail plate 1; Also comprise: frame base 3, rubber bearing structure 2; Described rubber bearing structure 2 is placed in the support rail plate 1 time, and frame base 3 is trapped among support rail plate 1 and rubber bearing structure 2 together;
Described rubber bearing structure 2 is that sulfuration is bonded as an integral body with support rail plate 1 and frame base 3.
As seen from Figure 2: the material of support rail plate 1 and frame base 3 is a ductile iron in the utility model, good toughness, and bearing capacity is big; Rubber bearing structure 2 is a rectangle, and rubber bearing structure 2 is bonded as an integral body with support rail plate 1, frame base 3 sulfurations, and load is born by 1 time rubber bearing structure 2 of support rail plate, and is stressed even, can increase the service life.1 time rubber layer 2 of support rail plate produces compressive strain under load action, by adjusting rubber thickness and shape, improvement fastener rigidity makes it have better elastic and effectiveness in vibration suppression; Carry out the rail level Height Adjustment by height adjusting cushion plate under the rail 4; Gauge is then adjusted by gullet plate 5.
Claims (2)
