The specific embodiment

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

Structure of the present utility model such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: on the rail 11 of track centerline 10 both sides, a stop device is housed respectively; In each stop device, the oscillating axle 5 that is provided with driving, buffer gear and links to each other with bearing seat; The oscillating axle right-hand member is with the big gear wheel 35 in the key connection driver train, and the lateral cross section of its axis body is an elliptical shape; In the buffer gear, its assist spring 4, buffering backstop 16, swing backstop 6 are overlapped successively from left to right and are connected on the oscillating axle, the piston rod right-hand member head of its water bumper 17 and railway car wheel tread 18 bump with the baffle plate that cushions, swings backstop respectively and connect, and the gap between the baffle plate of piston rod right-hand member head and buffering backstop is 3-5mm.In the swing backstop housing, its upper and lower respectively is equipped with the slide block 19 on 2 contact oscillating axle planes.The angle of swing backstop swing is 0-90 °.

In the above-mentioned driver train: in its hood 9, can be provided with motor 12, reductor 13, power-transfer clutch 14, gear cluster 8.Gear cluster is made up of the large and small gear 35,23 of ingear.In the miniature gears, it is the groove that cup shape and its rim of a cup edge have 4 symmetries that thin end has tooth, butt end, is provided with axle sleeve 22 in the axis hole, and pinion shaft 21 1 ends are equipped with axle with baffle plate 24, shaft block ring 25, are connected with bearing 15 after other end warp beam sleeve stretches out.

Above-mentioned power-transfer clutch 14 can comprise friction plate assembly 26, clutch sleeve 27, spring 28.Clutch sleeve connects deceleration arbor 32 with key 30, is with 33,2 pressure spring plates 31 of 34,2 baffle plates of 1 shaft block ring on its body from left to right successively.Spring 28 is contained between the pressure spring plate, and clamp nut 29 abuts against on the pressure spring plate.Friction plate assembly is made up of staggered inside and outside friction lining between baffle plate, and the outside friction disc upper end connects with the groove embedding of the symmetry of miniature gears 23, and internal friction sheet lower end is stuck on the power-transfer clutch body.

The

bearing seat

3,7 of above-mentioned water bumper 17, reductor 13, motor 12 and oscillating axle, the bottom surface of its base and bearing 15 all can be connected with base plate 1, and base plate is fixed on the basis 36 by holding-down bolt 20.The optional product of using the QHCQ model of Wuhan Heng Hai company production of water bumper, parts such as cylinder body, perforated casing, piston component and orienting sleeve are equipped with in sealing in its casing; At piston rod cavity recoil spring is housed, stretches out on one section outer piston rod body of rod of casing dust ring is housed.Sequence number 2 is pressing plates of rail.

Below, sketch working process of the present utility model.

1. stop vehicle: when empty wagons has been arranged or during the locomotive head trailer, drive mechanism oscillating axle 5 is rocked to 90 ° by 0 °, then swing the baffle plate of backstop 6 and hold up, stand on 11 on the rail, at this moment, when if railway car wheel tread 18 collides with it, swing backstop 6 acts on assist spring 4 and water bumper 17 simultaneously with buffering backstop 16, and Vehicular impact power is absorbed, again by water bumper and the assist spring 4 anti-vehicle location that push away, can stop vehicle, make not rolling of vehicle (falling back).
