Description

Convertible hitch

Technical field

The utility model belongs to transport vehicle draw gear technical field, relates in particular to the convertible hitch of a kind of later-model rolling stock.

Background technology

Rolling stock is to adopt the chain hook connection mode to carry out the marshalling bonded assembly of train the earliest.This connection mode must be operated the screw coupling device with manpower, and labour intensity is big, inefficiency, and also operation has danger between two cars.In addition, this connection mode does not have elastic force, therefore, except that chain, hook, also must be equipped with heavy side buffer to vehicle, and its buffering effect is unsatisfactory, but also has increased the deadweight of vehicle.Afterwards, articulated type S. A. hitch came out, and this technical scheme structure is ingenious, swift to operate easy, safe and reliable, is adopted by many countries.But these two kinds of connection modes can't be docked mutually.Owing to historical, politics, the many reasons of economic dispatch, still can not eliminate the screw coupling device fully now in some countries and regions, the vehicle of two kinds of different connection modes is present in the same railway network simultaneously often, newly purchase vehicle and can only in two kinds of connection modes, select one, this has greatly limited freely organizing into groups of train, and transport capacity can not be given full play to.On some outlet rolling stocks, adopt joint gib head and the convertible draw gear of chain as far back as eighties of last century China's sixties, solved this problem better.But, have only the chain in the screw coupling device on this draw gear, and lack corresponding gib head.In the chain hook connection mode, generally all be that chain separately is articulated on the corresponding gib head of the other side's vehicle, one is used for traction, and another root is standby.And in prior art, the chain of the other side's vehicle can't be mounted on this vehicle, and this does not meet the routine techniques requirement of adopting the chain hook connection mode.

Summary of the invention

The purpose of this utility model overcomes the deficiency of above-mentioned prior art exactly, provide a kind of and on same vehicle, can select connection mode according to the difference of butt joint vehicle, and when adopting the chain hook connection mode chain, the convertible hitch that gib head can articulate mutually of adjacent two joint vehicles.

The purpose of this utility model is achieved in that a kind of convertible hitch, by the joint gib head, screw coupling device and coupler body constitute, the tail end of the front end of coupler body and joint gib head all is the U-shaped structure that has the vertical pivots hole, the U-shaped tail end of joint gib head inserts the inboard of the U-shaped front end of coupler body, the gib head tail end that has the vertical pivots hole of screw coupling device inserts the inboard of joint gib head U-shaped tail end, the gib head of joint gib head and screw coupling device couples together by pivot in the pivot hole and coupler body, and can pivot be that rotate with respect to coupler body at the center, the chain link of the chain fixed end of described screw coupling device hangs over the neck of gib head by bearing pin.

This convertible hitch also can be that the front end of coupler body is the not wide E shape structure that has the vertical pivots hole, the tail end of joint gib head is the U-shaped structure that has the vertical pivots hole, the U-shaped tail end of joint gib head inserts the lower inside of the E shape front end of coupler body, the gib head tail end that has the vertical pivots hole of screw coupling device inserts the inboard of joint gib head U-shaped tail end, the chain link of the chain fixed end of screw coupling device inserts the upper inner of the E shape front end of coupler body, the joint gib head, the chain link of the gib head of screw coupling device and chain fixed end couples together by pivot in the pivot hole and coupler body, and can pivot be that rotate with respect to coupler body at the center.

In order to realize the purpose of this utility model better, correspondence is provided with knock hole on the U-shaped of the gib head tail end of described screw coupling device, the U-shaped tail end of joint gib head and coupler body or the E shape front end, can be individually fixed in work or rest position to the gib head of screw coupling device, joint gib head by locating dowel pin.

Adopt the technical solution of the utility model, because the gib head of joint gib head and screw coupling device can pivot be that rotate with respect to coupler body at the center, thereby can dock with the vehicle that adopts different connection modes, particularly when adopting the screw coupling device, can realize that chain on adjacent two vehicles is articulated to the routine techniques requirement on the corresponding gib head of the other side mutually, this is very beneficial for adopting the screw coupling device on the superseded rolling stock of progressive mode, can avoid because of the vehicle connection mode is carried out the tremendous economic pressure that disposable technological change brought.
