Joint sealing coupling of the rail motor set

Technical field

The utility model relates to the motor train unit connected system, refers in particular to a kind of Joint sealing coupling of the rail motor set.

Background technology

Joint sealing coupling of the rail motor set is a kind of being used for to save the device that compartments interconnect with two on the train, so-called motor train unit are meant the passenger train that is equipped with the modern service facility that a kind of self-powered, fixing marshalling, two ends can be driven, its speed per hour is up to the hundreds of kilometer, because train running speed is than very fast, tractive force between compartment and compartment is quite big, common hitch can not adapt to, and therefore, is badly in need of a kind of high-intensity hitch.

Summary of the invention

The purpose of this utility model is to design a kind of Joint sealing coupling of the rail motor set, improves the structural strength of hitch by structural development.

The technical scheme that provides according to the utility model has convex cone at the front end of hook body, at the tail end of hook body connecting bore is arranged; The profile of convex cone is the glans penis shape, and there is cavity inside, on the anterior sidewall of convex cone three holes is arranged, and it is characterized in that: it is linear that the cross-sectional plane of convex cone is conic, and the cross-sectional plane of convex cone increases the formation curved surface gradually from the front portion to the rear portion; The rear portion inner chamber of convex cone has curved wall, and this curved wall forms coupler knuckle chamber to the convex cone sunken inside.At the junction surface of curved surface and curved wall is great circle arc R transition, and the radius of this great circle arc R is 25～35 millimeters; There is cavity hook body inside, and the hook body is rectangular near the transversal surface of tail end, the circular arc r transition of the bight of rectangle, and the radius of circular arc r is 16～20 millimeters; The wall thickness of the wall thickness of convex cone and hook body is 12～16 millimeters.

Upside outside wall surface at the hook body is provided with the reinforced rib of vertically arranging along the hook body.The front portion of hook body from after forward gradually to both sides expansions, form enlarged portion, in the both sides of the edge of this enlarged portion adapter plate is set, mounting hole is set on adapter plate.The front end face of enlarged portion is the plane, and convex cone protrudes on this plane.

The utility model has the advantages that:, reduced the stress of connecting portion by the transition arc radius of increase convex cone inner chamber junction and the bight arc radius of hook body afterbody rectangular configuration; Increase the wall thickness of convex cone and the wall thickness of hook body simultaneously, therefore the structural strength of tightlock coupler is improved.Increase a reinforced rib of vertically arranging along the hook body in the middle of the upside outside wall surface of hook body, its effect is further to increase the rigidity of hook body and structural strength, and effectively avoided the generation of horizontal casting crack, thereby the realization Joint sealing coupling of the rail motor set draws 160 tons of tons and presses the technical requirement of 310 tons of tons, prolong service life, guaranteed traffic safety.Hitch after the improvement not only satisfies the needs of 200km/h motor train unit, and has satisfied the needs of the above motor train unit of 300km/h.

The specific embodiment

As shown in the figure: the front end at hook body 3 has convex cone 2, at the tail end of hook body 3 connecting bore 4 is arranged; The profile of convex cone 2 is the glans penis shape, and there is cavity 12 inside, and porose 1 on the anterior sidewall of convex cone 2, it is linear that the cross-sectional plane of convex cone 2 is conic, and the cross-sectional plane of convex cone 2 increases from the front portion to the rear portion gradually, forms curved surface 14; The rear portion inner chamber of convex cone 2 has curved wall 13, and this curved wall 13 forms coupler knuckle chamber to convex cone 2 sunken insides; Junction surface at curved surface 14 and curved wall 13 is great circle arc R transition, and the radius of this great circle arc R is 25～35 millimeters; There is cavity 16 inside of hook body 3, and hook body 3 is rectangular near the transversal surface of tail end, the circular arc r transition of the bight of rectangle, and the radius of circular arc r is 16～20 millimeters; The wall thickness of the wall thickness of convex cone 2 and hook body 3 is 12～16 millimeters.

Upside outside wall surface at hook body 3 is provided with the reinforced rib of vertically arranging along hook body 3 11.The front portion of hook body 3 from after forward gradually to both sides expansions, form enlarged portion 8, in the both sides of the edge of this enlarged portion 8 adapter plate 7 is set, mounting hole 6 is set on adapter plate 7.The front end face of enlarged portion 8 is plane 15, and convex cone 2 protrudes on this plane 15.

Two hooks connect when hanging, and as shown in Figure 4, convex cone 2 injects in the corresponding concave cone of the other side hole.At this moment the curved surface 14 of convex cone 2 is oppressed the other side's hook tongue 17 rotations in advancing, and makes spring 21 tensions of separating shank 20, and hook tongue 17 rotates 40 ° in the counterclockwise direction.After two hook joint faces contacted, the curved surface 14 of convex cone 2 was no longer oppressed the other side's hook tongue 17, at this moment, because the tension of spring 21 makes hook tongue 17 return to original state, promptly was in locked position of coupler.

During uncoupling, as shown in Figure 5, operating personal rides over one of them hook lock 18 on the boss 19 of the other side's hitch earlier, the pulling force that overcomes retracing spring 21 is then pulled and is separated shank 20, the projection 23 of hook lock 18 fastens the projection 22 of uncoupling bar 20 automatically during to the uncoupling position, make and separate shank 20 and be fixed on the uncoupling position, as long as train separately, hitch will separate automatically; Hitch is separated into to a certain degree hook lock 18 and separates shank 20 and will throw off automatically, separating shank 20 after throwing off automatically resets under the pulling force of spring 21, hook lock 18 also automatically resets under the gravity of self, and hitch was in and waited to hang the position this moment, need not other operation of operating personal.This kind structure operation is simple, reliable effect, and higher processing safety is arranged.Operating personal is separated shank 20 and is made it be fastened the back by hook lock 18 just can to need not other operation away from vehicle, guarantee the safety of operating personal, can also shorten the time of uncoupling simultaneously greatly, the efficient of raising train marshalling list pulling.
