Automatic hooking-unhooking device

Abstract

The invention discloses an automatic hooking-unhooking device, which comprises a hook component, a hook hooking-unhooking driving component and a case, wherein the hook component comprises a hook and a boom, the hook hooking-unhooking driving component at least comprises a driving part and a return part, the return part has pretightening force for driving hook separate, and the driving part, under the action of upward force which is generated by the upward relative motion of the boom, overcomes the pretightening force of the return part and drives a resisting arm of a half hook I and a resisting arm of a half hook II to carry out relative motion so as to form a hook structure for holding a coronary head. In need of hooking before lifting and unhooking after landing, the boom fixed on a workpiece is used for carrying out upward relative motion, so as to drive the hook to clamp with the lower part of the coronary head of the boom and break away from the coronary head, and thus realizing automatic hooking and unhooking. The hooking and unhooking of the lifting are sensitive and stable, and an external force leads the hook to be clamped tightly during the lifting, thus the device is high in reliability, contributed to improving work efficiency, and is suitable for devices for swing large-sized workpieces in high risk or with high safety requirements, such as electroslag and the like.

Description

technical field [0001] The invention relates to an accessory of a hoisting device, in particular to a device capable of automatic hooking and unhooking. Background technique [0002] Hoisting and lifting are important processes in construction, production and maintenance. For example, in the refining process of steelmaking, it is inevitable to lift the electroslag ingot during the remelting process of the electroslag ingot; the method usually used in the prior art is to weld a lifting ring on the top of the electroslag ingot, Then use a common hook for hoisting. The replanting method is relatively primitive, requiring manual hanging and uncoupling processing; for continuous production operations, the efficiency is significantly lower; especially when the length of the electroslag ingot is longer, the operation is more complicated and the safety is poor. In order to solve the above problems, automatic hooking and unhooking devices have occurred. A series of automatic trans...

AI Technical Summary

Problems solved by technology

A series of automatic transfer devices have emerged. Although they can achieve automatic hooking and uncoupling to a certain extent, their reliability is low and they cannot be used in high-risk industries, especially for lifting large equipment.
