Abstract

The traditional crane competition structure adopts an independent clamping jaw or an independent lifting rod structure, the independent clamping jaw structure clamps the side wall only by the clamping jaw in the process of carrying an object, and the object is difficult to stop to a designated position rapidly due to the fact that the object is thrown outwards under the action of inertia force in the starting, accelerating and steering processes of the device. And each time get the thing all need crane means hover in goods shelves the place ahead and carry out the altitude mixture control, waste time. The independent lifting rod structure cannot limit the movement of the object along the lifting rod direction, when the object is put down to leave, the object can be possibly taken away to slide along the lifting rod, so that after the object reaches the target position, the position of the object is deviated, and the position cannot be accurately admitted. Therefore, the lifting rod structure can realize that the whole carrying object is placed at the bottom of the device, the left and right interval positions are fixed, the repeated carrying and position adjustment are avoided, the clamping jaw structure can be placed at the position where the clamping object is flexibly adjusted to the appointed position, and the combined use of the lifting rod structure and the clamping jaw structure can greatly improve the flexibility of carrying and reduce the control requirement of precision, so that the service time is shortened.
