The working principle of the utility model is as follows:
when the coupler 14 needs to be removed, the push rod of the power driving device 11 extends out to drive the driving rocker arm 8 and the third lifting hook rod 6 to rotate around the hinge point on the support 4, so as to drive the second lifting hook rod 2 to rotate around the hinge point on the support 4, and the second lifting hook rod 2 drives the lifting hook chain 19 to lift, so as to lift the coupler pin 15. When the coupler pin 15 is lifted in place, the power driving device 11 sends a signal from the stroke sensor 21, the power driving device 11 stops working, the coupler 14 coupler knuckle is opened, the automatic uncoupling action is completed, then the push rod of the power driving device 11 returns to the standby position, the second lifting hook rod 2 and the third lifting hook rod 6 automatically reset, and the lifting hook chain 19 is in a free telescopic state so as to ensure that the coupler pin 15 can automatically fall down when the coupler 14 needs to be coupled.
When the coupler 14 needs to be connected, the coupler pin 15 is collided with a torpedo car or a molten iron ladle car through a locomotive and automatically falls down, the coupler pin 15 falls in place, so that the position sensor 18 senses the lower end part of the coupler pin 15 and gives a coupling in-place signal, and the coupler 14 is coupled. In the above-mentioned working process, the limit stop who is located second lifting hook pole 2 top that sets up on train frame 3 can restrict the highest lifting position of second lifting hook pole 2, prevents that power drive unit 11 from the stroke sensor 21 in area from damaging under the unexpected circumstances such as, and it is too big to lead to coupler pin 15 to promote the range, damages relevant equipment facility.
In addition, in the case of driving the unhooking by the power driving device 11, since there is a free area with a rotation angle of 120 ° in cooperation of the first hinge sleeve 5 and the second hinge sleeve, the first hook lifting lever 1 does not rotate with the rotation of the second hook lifting lever 2 and the third hook lifting lever 6, but remains in place. Similarly, when the power driving device 11 is abnormally disabled, the manual hook lifting handle 20 can be operated manually to drive the first hook lifting rod 1 to rotate, so as to drive the second hook lifting rod 2 to rotate, and the hook pin 15 can be lifted to achieve the hook disengaging effect.
Therefore, the device not only can realize automatic uncoupling of the car coupler 14, but also skillfully solves the problem that contradiction is generated between manual uncoupling and automatic uncoupling, and keeps the mode of manual uncoupling, so that manual operation can be adopted under abnormal conditions, and the production task is not influenced.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the scope of the claims of the present invention.
