Abstract
The utility model belongs to the traffic technical field, in particular to an improved railway switch elastic slide plate, comprising a sliding plate, a sliding base board and an elastic element; wherein, steps are arranged under the two ends of the sliding plate, and a tongue depressor is arranged above the two ends of the sliding base board; one side of the outer surface of the step matches the inner surface structure of the elastic element, and one side of the step is embedded in the elastic element; whereas, one side of the outer surface of the elastic element matches the inner surface structure of the tongue depressor, and one side of the elastic element is embedded in the tongue depressor; moreover, the tongue depressor is lap jointed with the step. Based on the former elastic slide plate, the utility model maintains the elasticity of the slide plate and promises the joint intensity and reliability in the elastic element, base board and the sliding plate of the elastic slide plate, as well as enhancing the safety reliability of the elastic slide plate, reducing the protection maintenance of the railway switch and prolonging the service life of the elastic slide plate, thereby improving the safety reliability of the train running through the railway switch and enhancing the comfort level of the train running through the railway switch as well as promising no increase to the producing cost.
Description
Technical field
The utility model belongs to the traffic technique field, is specifically related to a kind of follow-on railway switch elasticity slide plate.
Background technology
At present in the railway switch structure, the major function of slide plate is slide plane to be provided and to bear the train load that transmits on the tongue heart rail for point tongue and heart rail.Original elasticity turnout baseplate structure solved to a certain extent traditional slide plate rigidity big, can not decay effectively and the vibration that isolated train produces and the problem of impact, improved the functional performance of slide plate.But its structure reliability is to rely on the flexible member and the effective connection of sliding bed platform and sliding bed base plate to realize to a great extent, (greasy dirt is heavy because the rail track site environment is abominable, the temperature difference is big etc.), the slide plate bearing load is big, bond strength to former elasticity slide plate has a significant impact, in case flexible member lost efficacy with the connection of sliding bed platform and sliding bed base plate, descended to the application life of slide plate, cause the structural stability of elasticity turnout baseplate to descend, reduced buckle press to rail, make the degree of comfort decreased of train, also can bring certain adverse effect to the even running of train, the safe operation to train when serious constitutes a threat to.
Summary of the invention
The purpose of this utility model is to provide a kind of follow-on railway switch elasticity slide plate of simple in structure, long service life.
The follow-on railway switch elasticity slide plate that the utility model proposes is made up of sliding bed platform 1, sliding bed base plate 2, flexible member 3, its structure such as Fig. 1-and shown in Figure 2.Wherein, the below at sliding bed platform 1 two ends is provided with step 4, the top at sliding bed base plate 2 two ends is provided with presses tongue 5, external surface one side structure of step 4 and the inner surface structure of flexible member 3 coupling, step 4 one sides are embedded in the flexible member 3, external surface one side structure of flexible member 3 is complementary with the inner surface structure of pressing tongue 5, and flexible member 3 one sides are embedded in presses in the tongue 5, and presses tongue 5 and step 4 overlap joints.
In the utility model, the gradient of sliding bed platform step 4 is 5 °～10 °.
In the utility model, pressing the tongue 5 and the lap width of step 4 is 8-12mm.
In the utility model, between the sliding bed platform 1 of turnout baseplate and the sliding bed base plate 2 flexible member 3 is set, adopt bonding way that flexible member 3, sliding bed platform 1 and sliding bed base plate 2 are linked to each other, it is effectively fixing that the pressure tongue 5 of sliding bed base plate will be slided a platform 1 by flexible member, sliding bed platform 1 under extreme conditions also can not come off, also make the elasticity of slide plate obtain performance simultaneously.Its central role is with pressing tongue 5 to push down flexible member 3 and sliding bed platform 1, control the displacement of sliding bed platform 1 and improve the stressed of flexible member 3.
The utility model improves by the structure to slide plate, make it on the basis of former flexible slide plate, keep the elasticity of slide plate, and prevented the connection inefficacy of slide plate flexible member and sliding bed platform and sliding bed base plate, make the structural reliability of elasticity slide plate obtain reinforcement, reduced the maintenance of track switch, prolong the application life of elasticity slide plate, improve the security reliability of train operation by track switch, and the comfortableness can also further improve high train by track switch the time.
The utility model is a kind of anyhow to follow-on elasticity slide plate that certain rigidity is all arranged, can give full play to the spring function of flexible member in the slide plate, ensure between sliding bed platform, base plate, the flexible member connection reliability is arranged, improve the condition of work of track switch, reduce the shock and vibration that produce when train is crossed trouble, improve the stationarity and the safety of train operation, reduce the maintenance of track switch, increase the service life.The utility model has solved former elasticity slide plate flexible member and has slided between bed platform, base plate and connect defect problem, and elasticity slide plate overall performance and reliability are obviously improved, and manufacturing cost does not increase, and wide application prospect is arranged.
Description of drawings
Fig. 1 is a structural diagrams of the present utility model.
Fig. 2 is a decomposition texture diagram of the present utility model.
Number in the figure: 1 is sliding bed platform, and 2 for sliding the bed base plate, and 3 is flexible member, and 4 are sliding bed platform step, and 5 is that sliding bed base plate is pressed tongue.
The specific embodiment
Narrate embodiment of the present utility model below in conjunction with Fig. 1 and Fig. 2.
Embodiment 1: in the slide plate structure, flexible member 3 is set between sliding bed platform 1 and the sliding bed base plate 2, adopt bonding way that flexible member 3, sliding bed platform 1 and sliding bed base plate 2 are linked to each other, can isolate fully like this by the propagation of train wheel track vibration by point tongue, sliding bed platform 1 and sliding bed base plate 2, flexible member 3 can also reduce the generation of train wheel track impact force.In flexible member 3, sliding bed platform 1 and sliding bed base plate 2 structures, the two ends of sliding bed base plate 2 are provided with respectively presses tongue 5, when sliding bed platform 1 is subjected to dynamic action, push down flexible member 3 and sliding bed platform 1 by pressing tongue 5, control the upper and lower displacement of sliding bed platform 1 and move horizontally,, make whole slide plate have desirable three-way rigidity and stability by rationally selecting for use of elastomeric material, also guaranteed the safety of structure, simultaneously flexible member 3 has been within the rational field of load.In implementation process of the present utility model, the rigidity of flexible member 3 is selected and can be determined according to the line track rigidity requirement, and the material of flexible member 3 is selected and should be determined according to manufacturing cost and service condition, generally adopts elastomeric material.
