Abstract
The invention relates to a locomotive coupler, in particular to a locomotive coupler opening device which comprises a lifting rod and a lifting rod base plate fixed on a locomotive body. A connecting hole for the lifting rod to penetrate through is formed in the lifting rod base plate. The coupler opening device is also provided with an anti-lifting rod above the lifting rod. One end of the anti-lifting rod is connected with the locomotive body through a connecting mechanism. The other end of the anti-lifting rod is provided with a boss which penetrates through the connecting hole in the lifting rod base plate and presses the lifting rod in the connecting hole to prevent the lifting rod from rotating. The locomotive coupler opening device overcomes the shortcoming that a bolt needs to be disassembled when an existing pressing lock plate is used every time, so that operation is complex, and the bolt can easily lose efficacy after repeated disassembling, a coupler opening process is simplified, and coupler opening can be completed manually without a special tool.
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 drive hook by shadoof, because causing hitch, freely beating of shadoof automatically open the situation of hook when preventing that locomotive from moving under complex environment, conventionally above shadoof, add compression jam plate, jam plate and shadoof seat board are bolted, hitch need unload bolt with special tool while hanging together minute hook, comparatively trouble, seriously restricts locomotive maintenance operating cycles, affects locomotive efficiency.
Summary of the invention
The object of the invention is to, for the deficiencies in the prior art, provide a kind of locomotive coupler to open hook device, prevent that hitch from leaving hook automatically, reliable in structure, and it is simple to open hook process, without special tool, can complete out hook, raises the efficiency.
Technical scheme of the present invention is, a kind of locomotive coupler is opened hook device, comprise shadoof, be fixed on the shadoof seat board on car body, shadoof seat board is provided with the connecting bore passing for shadoof, open hook device and be also provided with the anti-shadoof that is arranged on shadoof top, one end of this anti-shadoof is connected with car body by bindiny mechanism, and the other end of anti-shadoof is provided with and through the connecting bore on shadoof seat board and by shadoof, is pressed in connecting bore and prevents the boss of shadoof rotation.
By installing shadoof additional, and be provided with in one end of shadoof the boss that shadoof is pressed on to connecting bore, can prevent freely beating of shadoof and cause that hitch leaves hook automatically.
Described connecting bore comprises circular hole, is communicated with circular hole and is placed in the rectangular opening of circular hole below, 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 greater 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.Because the long axis length of shadoof oval cross section is greater than the width of rectangular opening, the minor axis length of shadoof oval cross section is less than the width of rectangular opening, makes the shadoof can be parallel with rectangular opening Width through rectangular opening along minor axis, and can in rectangular opening, not rotate; The long axis length of oval cross section is less than Circularhole diameter simultaneously, can guarantee that shadoof can freely rotate in circular hole.
Described boss comprises 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 bore, 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 bore, but is less than the diameter of boss main body and the summation of convex body length, convex body can only be passed in rectangular opening, and can not in circular hole, pass.
Described bindiny mechanism comprises the chain being connected to form in turn by annulus, the crotch being connected with car body, and one end of described chain is connected with crotch by the first connecting panel, and the other end of chain is connected with anti-shadoof by the second connecting panel; Described the second connecting panel can rotate around annulus.After the second connecting panel and anti-shadoof connect, can also rotate around annulus, make convex body aim at rectangular opening or stagger with rectangular opening, realize the stable connection of anti-shadoof in connecting bore; Meanwhile, use the anti-seat of carrying of chain-driving, it is simple, convenient to use.
When locomotive need to be when the marshalling of other vehicles be connected, locomotive moves with corresponding vehicle coupler and completes and hit hook, afterwards shadoof is moved to anti-carrying in the rectangular opening of 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 rotate anti-shadoof, make the rectangular opening of anti-shadoof convex body and shadoof seat board not in same angle, the convex body of anti-shadoof is placed in anti-carrying outside seat board, anti-shadoof can be installed in shadoof seat board, and shadoof is fitted in rectangular opening by anti-shadoof, can prevent freely beating of shadoof, rotation.
When locomotive is in routine use process, when locomotive is transferred marshalling, in the time of need to opening hitch, anti-shadoof is turned to correct position, rotate anti-shadoof, the convex body of anti-shadoof is overlapped with the rectangular opening of shadoof seat board, anti-shadoof can take out, then shadoof can move on in rectangular opening in circular hole from anti-carrying seat board, rotation shadoof and complete uncoupling action.
Anti-shadoof like this can play the effect of restriction hook shadoof, thereby avoids occurring in locomotive operation process the phenomenon of unhook.
Locomotive coupler of the present invention is opened hook device and has been overcome when original compression jam plate is used at every turn and need demounting bolt, causes trivial operations, and dismounting repeatedly, and bolt easily causes the problem of inefficacy, simplifies uncoupling process, adopts and manually without special tool, can complete uncoupling.
