Description
Technical field
The present invention relates to a kind of locomotive coupler, be specially a kind of locomotive coupler and open hook device.
Background technology
The hitch of existing locomotive is to carry out out hook by shadoof, in order to prevent locomotive from causing hitch automatically to open the situation of hook due to freely beating of shadoof when running under complex environment, above shadoof, generally add compression jam plate, jam plate is bolted with shadoof seat board, hitch hangs together and carries out to be unloaded by bolt with specific purpose tool during point hook, more bothering, serious restriction locomotive maintenance uses the cycle, affects locomotive efficiency.
Summary of the invention
It is an object of the invention to, for the deficiencies in the prior art, it is provided that a kind of locomotive coupler opens hook device, prevents hitch from automatically driving hook, and structure is reliable, and it is simple to open hook process, it is not necessary to specific purpose tool can complete open hook, improves efficiency.
The technical scheme is that, a kind of locomotive coupler opens hook device, including shadoof, the shadoof seat board that is fixed on car body, shadoof seat board is provided with the connecting hole passed for shadoof, open hook device and be additionally provided with the anti-shadoof being arranged on above shadoof, one end of this anti-shadoof is connected with car body by bindiny mechanism, and the boss preventing shadoof from rotating in the other end of anti-shadoof is provided through the connecting hole on shadoof seat board and shadoof is pressed on connecting hole.
By installing shadoof additional, and it is provided with the boss that shadoof is pressed on connecting hole in one end of shadoof, can prevent freely beating of shadoof from causing hitch automatically to drive hook.
Described connecting hole includes that circular hole connects the rectangular opening being placed in below circular hole with circular hole, and the width of described rectangular opening is less than the diameter of circular hole；Described shadoof is Elliptic Cylinder；The long axis length of shadoof oval cross section is more than the width of rectangular opening, and the minor axis length of shadoof oval cross section is less than the width of rectangular opening；The long axis length of described shadoof oval cross section is less than Circularhole diameter.Due to the long axis length of shadoof oval cross section more than the width of rectangular opening the minor axis length of shadoof oval cross section less than the width of rectangular opening, make shadoof can along short axle with rectangular opening width parallel across rectangular opening, without rotating in rectangular opening；The long axis length of oval cross section is less than Circularhole diameter simultaneously, it is ensured that shadoof can be freely rotatable in circular hole.
Described boss includes the convex body that columned boss main body and boss body end are stretched out laterally, and the external diameter of boss main body is less than or equal to the Circularhole diameter of connecting hole, and the width of convex body is less than the width of rectangular opening；The external diameter of boss main body is less than or equal to the Circularhole diameter of connecting hole, but is less than the diameter of boss main body and the summation of convex body length, makes convex body can only pass in rectangular opening, and can not pass in circular hole.
Described bindiny mechanism includes being sequentially connected with the crotch that the chain formed is connected with car body by annulus, and one end of described chain is connected with crotch by the first connecting plate, and the other end of chain is connected with anti-shadoof by the second connecting plate；Described second connecting plate can rotate around annulus.After second connecting plate and anti-shadoof connect, moreover it is possible to rotate around annulus, make convex body alignment rectangular opening or stagger with rectangular opening, it is achieved anti-shadoof being stably connected with in connecting hole；Meanwhile, using chain-driving to prevent carrying seat, it is simple, convenient to use.
When locomotive needs to be connected with other vehicle marshalling, locomotive moves and completes to hit hook with corresponding vehicle coupler, afterwards shadoof is moved in the anti-rectangular opening carrying seat board, then the convex body of anti-shadoof is overlapped with the rectangular opening of shadoof seat board, boss main body is corresponding with the circular hole of shadoof seat board, insert anti-shadoof, then anti-shadoof is rotated, make the anti-shadoof convex body rectangular opening with shadoof seat board not in same angle, the convex body of anti-shadoof is placed in be prevented carrying outside seat board, anti-shadoof can be installed in shadoof seat board, and shadoof is fitted in rectangular opening by anti-shadoof, freely beating of shadoof can be prevented, rotate.
When locomotive is during routine use, when marshalling transferred by locomotive, when needing to open hitch, anti-shadoof is turned to correct position, i.e. rotating anti-shadoof, make the convex body of anti-shadoof overlap with the rectangular opening of shadoof seat board, anti-shadoof i.e. can be taken off, then shadoof can move on in circular hole from anti-carrying seat board in rectangular opening, rotates shadoof and completes uncoupling action.
Such anti-shadoof can play the effect limiting hook shadoof, thus occurs the phenomenon broken off relations during avoiding locomotive operation.
Locomotive coupler of the present invention is opened hook device and is overcome when original compression jam plate uses every time and need demounting bolt, causes trivial operations, and repeatedly dismantles, and bolt easily causes the problem of inefficacy, simplifies uncoupling process, uses and manually can complete uncoupling without specific purpose tool.
