Abstract

The utility model which belongs to the technical field of coupling of vehicles, in particular to a technical improvement of the controlling and locking device for the vehicle coupler comprises a control part and a lock part and is characterized in that one end of the coupler lifting rod connected with a locking pin is provided with a control handle, and that steel wire rope connected with the control handle and a movable stop is arranged in the coupler lifting rod, and that a lock mechanism is arranged in the locking pin, which is connected with one end of a locking pin rod, the other end of which is connected with a coupler knuckle lock, and that the unlock of the locking pin can be realized by the control handle to achieve the control and lock of the coupler. Compared with the prior art, the utility model has the advantages of compact structure, being convenient and practical, not adding working procedures, not affecting the property of the original coupler and avoiding the automatic separation of the coupler effectively.

Description

Hitch control blocking device

Technical field

The utility model belongs to vehicle interconnection technique field, specifically is a kind of technological improvement of vehicle hitch control blocking device.

Background technology

In the prior art, the company of vehicle two hooks hangs, and all is to adopt the swivel hook tongue, inserts coupler knuckle lock, with coupler rotor lever and coupler body, scurries on the restriction coupler knuckle lock.Owing to do not control lock function, the generation that separates fault in the train operation automatically is more and more frequent, and the transportation safety of railway and economic loss are constituted very big prestige association.

Summary of the invention

The utility model hitch control blocking device has solved vehicle and has been in operation, and prevents to scurry on hook lock voluntarily, and the technical matters that causes hitch to separate automatically provides a kind of structure tight for guaranteeing railway operation safety, the automatic locking apparatus that dependable performance is convenient, practical.

The utility model is to realize like this, form by control part and locking part, it is characterized in that: an end of the hook shadoof that links to each other with last lock pin is provided with control handle, the steel rope that links to each other with movable stops with control handle is housed in the hook shadoof, in the last lock pin lockout mechanism is housed, an end of coupler rotor lever is connected with last lock pin, and the other end is connected with coupler knuckle lock, utilize control handle to realize unblanking of lock pin, to reach the purpose of hitch control locking.

The utility model compared with prior art has compact conformation, and is convenient and practical, do not increase task program, do not influence the performance of former hitch, can prevent effectively that hitch from separating the generation of fault automatically.

Description of drawings

Fig. 1 is the assembly drowing of hitch control blocking device

Fig. 2 is hitch control locking structure drawing of device

Among the figure: lock pin, 10 springs, 11 movable stops, 12 coupler rotor levers, 13 coupler knuckle locks, 14 push away iron on 1 handgrip, 2 control handles, 3 steel ropes, 4 hook shadoofs, 5 hook uncoupling rod brackets, 6 hook tongues, 7 knuckle pivot pins, 8 coupler bodies, 9

The specific embodiment

With reference to the accompanying drawings embodiment is further described, present embodiment is improved on existing No. 13, No. 2 action type hitches, and hitch control blocking device is made up of control part and locking branch; Control part is made up of handgrip (1), control handle (2), hook shadoof (4), steel rope (3); One end of the hook shadoof (4) that locking part links to each other with last lock pin (9) is provided with control handle (2), the steel rope (3) that links to each other with movable stops (11) with control handle (2) is housed in the hook shadoof (4), lockout mechanism (10), (11), (12) are housed in the last lock pin (9), one end of coupler rotor lever (12) is connected with last lock pin (9), and the other end is connected with coupler knuckle lock (13).During the decoupling device apportioned effort, grasp handgrip (1), press control handle (2), at this moment steel rope (3) upwards draws movable stops (11) and goes up lock pin (9) and coupler rotor lever (12) and be in free rotary state, firmly hook shadoof (4) is upwards mentioned then, coupler knuckle lock is mentioned unlock position or full open position of coupler, when two hooks connect operation, when hitch is even hung, coupler knuckle lock is at lock pin (9) in drive under the effect of gravity, coupler rotor lever (12), hook shadoof (4) is together toward falling, because last lock pin (9) is bigger with the coupler rotor lever gap, flexibly, again not on same straight line, so the gravity of last lock pin can make coupler rotor lever (12) deflect, when coupler rotor lever deflects into certain angle, movable stops (11) can fall automatically, the rotation of restriction coupler rotor lever and last lock pin, thus the portion of the exposing wound of coupler rotor lever is contacted with coupler body, block coupler knuckle lock can not on scurry, reach the purpose that automatically locks, so, when two hitches connect, do not need any operation.

Claims (1)

1, a kind of novel hitch control lock is decided device, form by control part and lock part, it is characterized in that: an end of the hook shadoof (4) that links to each other with last lock pin (9) is provided with control handle (2), the steel rope (3) that links to each other with movable stops (11) with control handle (2) is housed in the hook shadoof (4), lockout mechanism (10), (11), (12) are housed in the last lock pin (9), one end of coupler rotor lever (12) is connected with last lock pin (9), and the other end is connected with coupler knuckle lock (13).
