Automatic unhooking mechanism for hoisting equipment

Abstract

The invention relates to the technical field of hoisting equipment and discloses an automatic unhooking mechanism for the hoisting equipment. The mechanism comprises a suspended lifting hook, whereinan oil storage cavity is formed in the top end of the suspended lifting hook, an elastic pressing plate is arranged at the bottom of an inner cavity of the oil storage cavity, a hoisting pulley is fixedly mounted in the middle of the top end of the suspended lifting hook, an oil inlet is formed in the top of the inner cavity of the oil storage cavity and communicates with the interior of the hoisting pulley, a supporting connecting rod is arranged at one side of the top end of the suspended lifting hook in a threaded connection mode, and an unhooking sliding plate is clamped to the middle of an inner cavity of the suspended lifting hook. According to the automatic unhooking mechanism for the hoisting equipment, through the arrangement of an arc-shaped curved surface structure of the bottomof an inner cavity of the unhooking sliding plate, when the unhooking sliding plate slides upwards under the action of elastic force of a return spring, a rope suspended on the suspended lifting hookcan abut against the edge position of the suspended lifting hook all the time till the rope completely separates from the suspended lifting hook, and therefore the stability and smoothness of the automatic unhooking mechanism in the using process is further improved.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to an automatic decoupling mechanism for hoisting equipment. Background technique [0002] Hoisting equipment is an important part of cargo handling in industrialized and mechanized production. In order to optimize the hoisting process and reduce the labor intensity of personnel, a lifting device that can be automatically unhooked came into being. It can be automatically realized after the hoisting is completed. The detachment of the hook from the rope no longer requires human intervention and decoupling. [0003] For example, in the application number CN201920985092.1, a new type of hook with an automatic decoupling structure is provided with a first bracket and a second bracket, the upper end of the second bracket is hinged to the first bracket, and the spring deforms elastically to make the first bracket The first bracket and the second bracket drive the hook body to ...

AI Technical Summary

Problems solved by technology

[0008] The invention provides an automatic decoupling mechanism for hoisting equipment, which has the advantages of being able to actively decoupling the rope, avoiding incomplete decoupling and pulling the placed goods, and having the advantages of high safety and stability , to solve the problem that when the new hook is in the initial position, the hook body is always in a horizontal state. In order to prevent the rope hanging on the hook body from slipping, it
