Description
Technical field
What the utility model was specifically related to is a kind of track wheel skid, specifically a kind of railroad track buffering stop trochus.
Background technology
At present, existing wheel skid is mainly used in preventing that train from slipping car, ensures that vehicle can live in orbit by safe stopping, still, existing wheel skid can not ensure smooth running in the time that train slows down, easily there is a car phenomenon in train, affects the service life of train, simultaneously, passenger is in the time pausing car, can not stand firm, easily make passenger fall down, have an accident.
Utility model content
The purpose of this utility model is for solving above-mentioned deficiency, and a kind of railroad track buffering stop trochus is provided, thus realize wheel skid can prevent train slip car object, train is steadily slowed down.
The purpose of this utility model is achieved through the following technical solutions:
A kind of railroad track buffering stop trochus is provided, and skewed slot circle is arranged on axle, between skewed slot circle and axle, key is installed, and axle two ends are provided with wheel; Voussoir is arranged on respectively skewed slot circle both sides; Described voussoir is arranged on respectively holder inside, and holder is oppositely arranged; Holder inside is provided with high pressure water nozzle, and high pressure water nozzle is connected with water pipe; Movable back-up ring is arranged on holder by back-up ring rotating shaft; Frame bottom is provided with hydraulic actuating cylinder, and hydraulic actuating cylinder bottom is arranged on holder, between hydraulic actuating cylinder and frame, is connected with hydraulic oil pipe; Between holder and frame, be connected with water pipe.
Wherein, described holder is semicircular structure, and holder is oppositely arranged.
Wherein, described movable back-up ring rotates with respect to back-up ring rotating shaft.
Wherein, described voussoir is that elastomeric material is made, and described skewed slot circle is that elastomeric material is made.
The utlity model has following useful effect: the utility model is reasonable in design, can prevent that train from slipping car, simultaneously, at train in when brake, ensure the steady ramp to stop of train, prevent that passenger from being jolted in the time that train slows down, improve train safety in operation, have advantages of practical, safe.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The overall structure schematic diagram that Fig. 1 provides for the utility model embodiment;
The local structure for amplifying schematic diagram that Fig. 2 provides for the utility model embodiment;
Wherein, 1. frame, 2. hydraulic actuating cylinder, 3. hydraulic oil pipe, 4. water pipe, 5. holder, 6. wheel, 7. axle, 8. movable back-up ring, 9. back-up ring rotating shaft, 10. voussoir, 11. skewed slot circles, 12. keys, 13. high pressure water nozzles.
Detailed description of the invention
Below in conjunction with specific embodiment, such scheme is described further.Should understand these embodiment is for the utility model being described instead of limiting scope of the present utility model.The implementation condition adopting in embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.
Please refer to Fig. 1 to Fig. 2, the overall structure schematic diagram that Fig. 1 provides for the utility model embodiment; The local structure for amplifying schematic diagram that Fig. 2 provides for the utility model embodiment.
In a kind of specific embodiment, a kind of railroad track buffering stop trochus is provided, skewed slot circle 11 is arranged on axle 7, between skewed slot circle 11 and axle 7, key 12 is installed, and axle 7 two ends are provided with wheel 6; Voussoir 10 is arranged on respectively skewed slot circle 11 both sides; Described voussoir 10 is arranged on respectively holder 5 inside, and holder 5 is oppositely arranged; Holder 5 inside are provided with high pressure water nozzle 13, and high pressure water nozzle 13 is connected with water pipe 4; Movable back-up ring 8 is arranged on holder 5 by back-up ring rotating shaft 9; Frame 1 bottom is provided with hydraulic actuating cylinder 2, and hydraulic actuating cylinder 2 bottoms are arranged on holder 5, between hydraulic actuating cylinder 2 and frame 1, is connected with hydraulic oil pipe 3; Between holder 5 and frame 1, be connected with water pipe 4.
Concrete, described holder 5 is semicircular structure, holder 5 is oppositely arranged, when concrete use, in the time of train speed reducing, hydraulic actuating cylinder 2 promotes holder 5 to axle 7 direction operations, holder 5 is inserted in skewed slot circle 11 voussoir 10 gradually, voussoir 10 is connected with skewed slot circle 11 completely, train is slowed down gradually until stop, train is steadily stopped, high pressure water nozzle 13 sprays cold water to voussoir 10 with the gap place of skewed slot circle 11, can make voussoir 10 and skewed slot circle 11 desuperheats, improve the service life of voussoir 10 and skewed slot circle 11; In the time that needs start train, hydraulic actuating cylinder 2 drives holder 5 to away from 7 direction operations, makes holder 5 that voussoir 10 is separated with skewed slot circle 11 gradually, and now, axle 7 can freely rotate, and train brings into operation.
Further, described movable back-up ring 8 can rotate with respect to back-up ring rotating shaft 9, and movable back-up ring 8, can be after voussoir 10 contacts with skewed slot circle 11 for sealing function, ensure that voussoir 10 is closely connected with skewed slot circle 11, improve the frictional property between voussoir 10 and skewed slot circle 11.
Further, described voussoir 10 is made for elastomeric material, and described skewed slot circle 11 is made for elastomeric material, improves the frictional property between voussoir 10 and skewed slot circle 11.
Finally it should be noted that the only restriction for the technical solution of the utility model is described but not to the utility model protection domain of above embodiment.Although the utility model is explained in detail with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that and can modify or be equal to replacement the technical solution of the utility model, and do not depart from essence and the scope of technical solutions of the utility model.
