Abstract
The invention provides a wagon coupler unlocking mechanism which comprises the components of a coupler release rod, a release rod base, a supporting base and a coupler release chain. The coupler release rod is arranged on the release rod base and the supporting base and can freely rotate relative to the release rod base and the supporting base. One end of the coupler release chain is rotatably connected with the end of the coupler release rod, and the other end is rotatably connected with a rotating shaft on the wagon coupler. Through rotating the coupler release rod, the coupler release chain is tightened and the rotating shaft on the wagon coupler is driven to rotate, a lock iron block in a wagon coupler chamber is lifted and the wagon lock is in an unlocked state. After the coupler release rod is placed down, the lock iron block falls by means of self weight, and the rotating shaft returns to a locked state, thereby finishing a whole wagon hook unlocking process. The wagon coupler unlocking mechanism has advantages of simple and reliable structure and convenient detachment. The wagon coupler unlocking mechanism can totally satisfy the general requirement and interchange requirement of a railway wagon coupler buffer device in the Commonwealth of the Independent States (CIS), European countries and some African countries. Furthermore wagon utilization efficiency is improved.
Description
Technical field
The invention belongs to railway traffic technical field, particularly a kind of hitch release mechanism and there is the coupler and draft gear of this release mechanism.
Background technology
Coupler and draft gear is the important component part of rail vehicles.Because of policies of various countries regulation and technical standard, there is some difference, the factor that railway truck organizational systems, running velocity, line condition, buffer capacity etc. affect coupler and draft gear type selecting is different, causing its coupler and draft gear parts to configure also to distinguish to some extent, inevitably there is difference in hitch opening ways and mounting structure.
Art technology is known, and what the railway vehicle comprising the overwhelming majority of countries in the world of China adopted is meet the upper action type of AAR standard or lower action type hitch, opens the hitch unlocked, call action type hitch by the lift system being located at gib head top; Action by means of the ejector pin being located at gib head bottom realizes opening the hitch unlocked, and is lower action type hitch.At the Commonwealth of Independent States (CIS), Europe and African Countries, adopt the hitch of similar Г О С Т standard, its opening ways is different from above-mentioned two kinds of forms completely, causes the existing coupler and draft gear of China can not use with its exchange, more can not connect with the existing lorry in locality and hang.
In sum, a kind of simple and reliable, convenient disassembly is provided, is applicable to the release mechanism of similar Г О С Т standard hitch, realize the unlocking function being different from AAR standard hitch, become the technical barrier that those skilled in the art are urgently to be resolved hurrily.

Hitch release mechanism of the present invention, hook described in it is carried chain and is made up of some chain links and the chain hoof ring that is arranged on two ends, and the chain hoof ring that chain two ends carried by described hook is rotationally connected with hook shadoof end and the turning cylinder that is positioned at hitch side respectively.
Hitch release mechanism of the present invention, hook shadoof two ends described in it are folding shape structure, and shown folding shape structure makes hook shadoof be limited between uncoupling rod bracket and supporting seat and has certain deviation amount.
Hitch release mechanism of the present invention, it is provided with rotation hole with angle on described uncoupling rod bracket, described rotation hole top is circular hole, bottom is flat hole, the angle of inclination of described rotation hole is identical with the placement gradient of hook shadoof, described hook shadoof section corresponding to rotation hole is shaped to the flat structure coordinated with described rotation hole, during hitch blocking, the flat structure of described hook shadoof is placed in the flat hole of rotation hole bottom, when unlocking hitch, the flat structure of hook shadoof is mentioned in the circular hole on rotation hole top with swivel hook shadoof.
Hitch release mechanism of the present invention, it is used in the through hole of hold-down hook shadoof at described supporting seat, is provided with lining between supporting seat and hook shadoof.
A kind of coupler and draft gear with described hitch release mechanism, comprise striker, hitch and hitch release mechanism, it is characterized in that: the supporting seat in described hitch release mechanism to be installed on below hitch and to be fixedly connected on striker, and the uncoupling rod bracket in described hitch release mechanism is fixedly connected on the bearing of floor underframe for vehicle.
The present invention utilizes lever principle, by swivel hook shadoof hand handle, hook shadoof is rotated around supporting seat, thus the turning cylinder making hook carry on the exceptionally straight rear drive hitch of chain rotates, lift the lock iron in draw gear chamber, hitch is unblanked, after putting down hook shadoof, car coupler knuckle lock falls by deadweight, turning cylinder gets back to initial position, and blocking got back to by hitch, completes whole hitch releasing process, and hook is carried the turning cylinder of chain butt hook shadoof and hitch side and leaves certain loose allowance, can safety curve when ensure that vehicle operating.
The present invention has simple and reliable for structure and feature that is convenient disassembly, obviously, compared to the mode introduced in background technology, above-mentioned hitch release mechanism is different from existing upper action type and lower action type two kinds and separates hook forms, meets the Commonwealth of Independent States (CIS), the General Requirement of Europe and African Countries railway freight-car coupler shock absorber and exchange requirement completely.
