Abstract

The utility model relates to a buffer stop arrangement for subway vehicles, which is composed of a vehicle stopping preload damper, a stop buffer or a slide buffer stop, a buffering bearing and a coupler positioner, wherein, the vehicle stopping preload damper, the stop buffer or the slide buffer stop is arranged on the stock rail of a line; the buffering bearing is fixed on the connecting frame of the stop buffer or the slide buffer stop by bolts; the coupler positioner is sheathed on the coupler of the railway vehicle. When a vehicle bumps into the stop buffer, the coupler positioner and the buffering bearing contact steady and close, and the vehicle is slowed down and stopped by the friction resistance generated between the stop buffer, preload damper and the rail, achieving the goal of both not causing damage to the vehicle and guaranteeing safe driving.

Description

A kind of railcar alley stopping device

The utility model relates to and prevents on a kind of subway line that railcar from going out the safety precaution alley stopping device of line end and belonging to the safety of railway traffic technical field.

At present, subway train is malfunctioning or control improper etc. formerly thereby go out line end because of stop mechanism sometimes, causes derail or breaks the accident of vehicle.The CDH type sliding type stop buffer of on ground rail, using, stop buffer (Chinese patent, ZL93200360.5), sliding type car bumper (Chinese patent, ZL94206405.4) and keeping off a car of being complementary with it give and press damper (Chinese patent, ZL93241109.6), because the railcar hitch is different with the structure of railway vehicle coupler, these stop buffers all can not directly adopt.

The purpose of this utility model provides a kind of simple in structure, and buffering, deceleration and stopping performance is good, and installation, maintenance is convenient, is fit to the alley stopping device of railcar and circuit technical characterstic.

The purpose of this utility model is achieved in that

Give by keeping off a car and to press damper, stop buffer or sliding type car bumper, buffering bearing, hitch steady arm to form alley stopping device.Be that the son of will keeping off a car presses damper and stop buffer or sliding type car bumper to be installed on the subway line stock rail, the buffering bearing is installed on the link span of stop buffer or sliding type car bumper with the bolt and spring washer circle, and the hitch steady arm is sleeved on the hitch of railcar.The hitch steady arm is by with holes the aligning plate and draw spring, yoke plate, bolt, spring washer to form in centre, align plate and be sleeved on the hitch of railcar by plate hole, draw spring and the yoke plate that tie up to two ends are fixed on the end of railcar with the bolt and spring washer circle.The buffering bearing is made up of pedestal, yielding rubber plate, pressing plate, bolt, nut and spring washer, pedestal is installed on the link span of stop buffer or sliding type car bumper with bolt, nut and spring washer, and the yielding rubber plate is fixed on the pedestal with bolt, nut and spring washer by pressing plate.

Have at bearing middle part one be complementary with hitch top projection size, the corresponding preformed hole in position, when vehicle rushes at the buffering bearing of alley stopping device, projection inserts in the preformed hole of buffering bearing exactly, is issued to by whole in the control of laterally drawing spring and aligns that plate bears extraneous pressure and the purpose of not damaging vehicle and alley stopping device.

Further narrate the utility model below in conjunction with accompanying drawing:

Fig. 2 looks scheme drawing for the master of the utility model stop buffer;

Fig. 3 is the birds-eye view of Fig. 2;

Fig. 4 is an A apparent direction scheme drawing among Fig. 2;

Fig. 5 is the installation site front view of the utility model hitch steady arm;

Fig. 6 is the birds-eye view of the utility model Fig. 5;

Fig. 7 is the lateral plan of the utility model Fig. 6.

Give the alley stopping device of pressing damper 1, stop buffer or sliding type car bumper 2, buffering bearing 3, hitch steady arm 5 to form by keeping off a car, to keep off a car earlier to give presses damper 1 and stop buffer or sliding type car bumper 2 to be installed in respectively on the stock rail of subway line, to cushion bearing 3 usefulness bolts 9, nut 10, spring washer 11 then and be installed on the link span of stop buffer or sliding type car bumper 2, hitch steady arm 5 is sleeved on the hitch of railcar.Hitch steady arm 5 is by with holes the aligning plate 12 and draw spring 13, yoke plate 14, bolt 15, spring washer 16 to form in centre, aligning plate 12 is sleeved on the hitch of railcar by plate hole, draw spring 13 1 ends to connect and align plate 12, the other end is connected with yoke plate 14, and yoke plate 14 usefulness bolts 15 and spring washer 16 are fixed on the end of vehicle.Buffering bearing 3 is made up of pedestal 6, yielding rubber plate 7, pressing plate 8, bolt 9, nut 10 and spring washer 11, and buffering rubber portion has one and hitch top projection size is complementary, the corresponding preformed hole in position.When buffering bearing 3 is assembled with the sliding type car bumper, car bumper indicator 4 is installed between pedestal 6 and support.

When the hitch of subway vehicle knocks the buffering bearing 3 of alley stopping device, the hitch lug boss just inserts in the preformed hole of buffering bearing 3, the non-bossing of hitch contacts with the pressing plate 9 of buffering bearing 3 by the plate 12 that aligns of steady arm 5, compressing yielding rubber plate 7 bufferings and promotion stop buffer or sliding type car bumper 2 road along the line stock rails slide, promoting keeping off a car of vehicle operating direction successively gives and presses damper 1 together to slide, because the Brake Block of stop buffer or sliding type car bumper 2 and keeping off a car is equipped with spring on the damper 1 respectively and gives depressor and be installed on the stock rail, so when sliding, strengthen friction drag gradually, consume the kinetic energy of operational vehicle, to the vehicle apply brake up to parking, prevent vehicle go out line end and take place the derailing or car accident.

The utlity model has following advantage:

1. simple in structure, reasonable stress, good stability.

2. easy for installation, the easy-maintaining maintenance.

3. the office of section of mechanism of keeping off a car of each of composite set is reasonable, have stronger shock resistance and The buffer-braking ability is guaranteed safety.
