Automatic butting and automatic detaching device for crane

Abstract

The invention relates to an automatic butting and automatic detaching device for a crane. The automatic butting and automatic detaching device for the crane comprises a shelf and a spreader, wherein suspenders are arranged at the bottom of the spreader, and horizontal rotating shafts are symmetrically arranged at the upper part of the shelf; the number of the horizontal rotating shafts correspondsto the number of the suspenders, and an inner disc is eccentrically arranged on the horizontal rotating shaft; the inner disc is rotatably connected with the horizontal rotating shaft, and a drivinggroove is formed in one side, close to the shelf, of the inner disc; the opening of the driving groove faces the shelf, and an inlet, an anti-off buckle and an outlet are sequentially formed in the driving groove from top to bottom; the side surface of the driving groove is provided with a shielding part for only allowing the anti-off buckle to move down, and one end of the anti-off buckle is hinged to the inner disc; the other end of the anti-off buckle is matched with the shielding part, and a horizontal shaft pin is arranged on the suspenders; the shaft pin is matched with the driving groove and can move up and down along the driving groove. The automatic butting and automatic detaching device for the crane provided by the invention can realize automatic butting and automatic detachingto save manpower, can prevent disconnecting, and is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to an automatic docking and automatic decoupling device for cranes. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and transports heavy objects horizontally within a certain range. At present, the free end of the steel wire rope of most cranes is fixed with a hook, and the hoisting object is hung with the hook for lifting. When it is necessary to lift the shelf , single hook lifting is prone to unbalance, so there is a spreader under the wire rope, and a symmetrical hook is set at the bottom of the spreader, which is used to lift the shelf to balance the lifting. Lifting with a hook has the following disadvantages: one is lifting At the same time, the worker hangs the hook, and when it reaches the destination, the worker takes off the hook again, which is time-consuming and laborious. If the shelf is larger, it is even more incon...
