Abstract
A buffer device for the steel rails is equipped to the connecting area of two steel rails which are adjacent to each other, the ends of two adjacent steel rails are wedge-shaped which are mutually coincident, a fishplate is equipped on the inner side of the connecting area of two adjacent steel rails and the outer side of the steel rail in the connecting area is provided with a deforming fishplate. The fishplate and the deforming fishplate are incorporated with two steel rails respectively through the connecting bolt and nut. Further, the upper wing periphery of the deforming fishplate is contacted with the upper wing periphery of the steel rail in coincidence with the upper surface of the upper wing periphery and upper surface of the steel rail both contacted with the wheel and the lower wing periphery is contacted with the lower wing periphery in coincidence. Besides, the fastening screw, the nut and the spring are fixedly-connect with the cross tie through the intermediate buckle pressing-connected with the fishplate and the deforming fishplate. The utility model has an advantage that the steel rails in the connecting area are formed as an integral body, therefore, when the trains pass through this area, no impact force is generated which not only prolong the working life of wheels and steel rails, but also eliminate the noise, further create the possibility of accelerating the speed of trains. Besides, the utility model is low in fabrication cost, convenient and guaranteed to operation.
Description
Technical field:
The utility model relates to a kind of rail facility, and two rails connects the rail buffer that impact force is located in the slit on the railway line especially for slowing down.
Background technology:
The existing device that is used to connect railway track is the gusset piece that is called as splice bar.It is installed in two one steel rails link place inboard and the outside, and fastening bolt is linked together the splice bar in the interior outside and rail.Because rail has the performance of expanding with heat and contract with cold, track bond place must leave for its flexible slit, and rail just can not twist.Wheel can produce with rail during through the slit and impact.Its consequence is the application life of reducing wheel and rail, and sends very big noise, causes noise pollution.Particularly behind the train speed raising, this impact force can increase along with the raising of speed, causes even more serious consequence.
Summary of the invention:
Task to be solved in the utility model is to overcome the above-mentioned disadvantage of existing railway track coupling arrangement, a kind of practicality is provided, can eliminate the rail buffer that train wheel and rail connection place produce impact force, make wheel roll rail away from, sail rail into and the distortion splice bar bears jointly by wheel through the load of connection place.
The technical solution that the utility model adopts is: the railway track buffer, be installed on two sections adjacent rail connection places, it is mainly by splice bar, middle buckle and fastening bolt nut, spring and attachment bolt, nut is formed, splice bar is loaded on the inboard of two sections steel connection places of adjacency, through attachment bolt, nut connects with two sections rail respectively, again through middle buckle and fastening bolt, nut, spring is installed on the sleeper, the wedge shape of two sections steel rail endses that it is characterized in that adjacency for coincideing mutually, distortion splice bar, splice bar are equipped with in the rail outside, connection place, the distortion fish tail is through attachment bolt, nut connects in aggregates with two sections rail respectively.
Top flange and the rail top flange of distortion splice bar coincide and touch, and top flange upper surface and rail upper surface jointly and wheel touch; Distortion splice bar bottom flange and rail bottom flange coincide and touch; Fastening bolt, nut, spring are fixed on the sleeper through the distortion of middle buckle crimping successively splice bar bottom flange, rail bottom flange.

Fig. 3 is a railway track buffer structure vertical view
The specific embodiment:
The utility model further specifies as follows in conjunction with concrete enforcement referring to accompanying drawing:
A kind of railway track buffer, referring to accompanying drawing 1,2,3, sleeper [1] has two rail [8], [13] in the bottom on it.The end machining of these two rail becomes the wedge shape of coincideing mutually.Article two, stay the slit A of a 10mm between the steel rail ends cammed surface.The splice bar [16] that uses on the present railway of the installed inside of rail, the outside of rail are installed distortion splice bar [9].Six attachment bolts [10] nuts [11] tighten together splice bar [6], distortion splice bar [9] and rail [8], [13].The utility model railway track buffer, its distortion splice bar [9] top flange and rail [8], [13] top flange coincide and touch, and the upper surface of top flange and rail [8], [13] upper surface jointly and wheel [7] touch, referring to accompanying drawing 1; Distortion splice bar [9] bottom flange and rail [8], [13] bottom flange coincide and touch.The middle buckle [2] of rail inboard adopts the middle buckle that uses on the present railway.Tighten the nut [3] on the sleeper, nut [3] is with regard to holddown spring [4], and spring [4] compresses middle buckle [2], and middle buckle [2] compresses rail [8], [13], and rail [8], [13] are fitted tightly with sleeper [1].The middle buckle [12] in rail [8], [13] outside is that this installs newly-designed buckle, tighten the nut [3] on the sleeper, nut [3] holddown spring [4], buckle [12] in the middle of spring [4] compresses, middle buckle [12] compresses distortion splice bar [9], distortion splice bar [9] compresses rail [8], [13], and rail [8], [13] are fitted tightly with sleeper [1].So, constitute the railway track buffer that can play cushioning effect.
The utility model railway track buffer great advantage is to make the rail of connection place to form an integral body.Train is through herein the time, and rail is pressed in wheel simultaneously and rolls steel rail ends away from, sails on steel rail ends and the distortion splice bar, and wheel drives to another rail from a rail and seamlessly transits, and can not produce impact force, also can not make a noise.Both prolonged the application life of wheel and rail, eliminated noise pollution again, also created condition for train speed raising.It is cheap, and is easy to use and reliable.
