Abstract
The invention provides an automatic hook picking device and method for a mine car based on a train jensey coupler. The device comprises a hook module, a mobile module and a connecting module. The automatic hook picking device of the mine car is arranged at the collision head position of the two mine cars, and the mine car automatically collides by sliding the mine car on the track. When two mine cars collide, the coupler knuckle connected with the two mine cars forms a hook state due to collision, the coupler knuckle rotates to a limiting position to form a lock iron descending space, at the moment, the wedge block is removed, the lock iron descends due to the action of gravity, the rotation of the coupler knuckle is limited, and the hook state is realized. When the explosion-proof motor is started, the wedge block is driven to move towards the lock iron through the ball screw mechanism, the lock iron moves upwards to be separated from the coupler knuckle, the coupler knuckle can rotate freely around the coupler knuckle pin at the moment, and at the moment, any mine car is pulled by the electric locomotive to achieve the unhooking state. The automatic hook picking device has the advantages of simple structure, convenience in operation and high reliability, and simultaneously can automatically finish hook and unhook, reduce labor intensity and improve the safety of mine car transportation.
