Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-6 , the present utility model provides a technical solution for a pin pulling device for a Janney coupler:

[0018] A pin pulling device for a Janney coupler includes a Janney coupler 1. One ends of the two coupler bodies 1.1 in the Janney coupler 1 away from the coupler tongue 1.2 are respectively fixed on the surface of the base 2 of the tail car and the traveling mechanism. A support plate 3 is fixed on the base 2, and a screw jack 4 is arranged on the support plate 3. The lower end of the screw rod 4.1 in the screw jack 4 is fixedly connected to one end of a universal joint 5. The other end of the universal joint 5 is connected to the upper end of a buffer chain 6. The lower end of the buffer chain 6 is connected to the upper end of the lock pin 1.3 in the Janney coupler 1. A proximity switch 7 is fixed between the lock pin 1.3 and the coupler tongue 1.2 on the upper surface of the coupler body 1.1. The proximity switch 7 is a photoelectric proximity switch, and the proximity switch 7 is electrically connected to a controller 8; the controller 8 is respectively electrically connected to the motors 4.2 in the two screw jacks 4, and a lift button 9 is arranged on the controller 8.

[0019] The buffer chain 6 includes: a rubber rod 6.1 and two lugs 6.2; the two ends of the rubber rod 6.1 are each fixed with a lug 6.2, which can play a certain buffering role during the pin pulling process of the screw jack 4 to avoid the fracture of the lead screw.

[0020] The working principle is as follows: during the preparation for closing of the tail car and the traveling mechanism, when the proximity switch 7 on the hook body 1.1 detects that the other hook body 1.1 is relatively close to a certain value, the proximity switch 7 will send the detected signal to the controller 8, and the controller 8 simultaneously controls the motors 4.2 in the two screw jacks 4 to rotate forward, and the lead screw 4.1 moves downward, so that the lock pressure plate 1.31 in the lock pin 1.3 is located on the unlocked surface 1.21 of the hook tongue 1.2. When the two hook tongues 1.2 are hooked to each other, the lock pressure plate 1.31 in the lock pin 1.3 falls on the lock groove surface 1.22 to achieve the locking function.

[0021] During the preparation for separation of the tail car and the traveling mechanism, a signal is given to the controller 8 by pressing the lifting button 9, and the controller 8 simultaneously controls the motors 4.2 in the two screw jacks 4 to rotate in reverse, and the lead screw 4.1 moves upward, so that the lock pressure plate 1.31 in the lock pin 1.3 leaves the lock groove surface 1.22, thereby realizing the separation of the two hook tongues 1.2 from each other to complete unlocking.

[0022] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
