Lifting hook anti-dropping device convenient for mounting and dismounting

Abstract

The invention relates to the field of hooks, in particular to an anti-dropping device for a hook which is convenient for installation and disassembly. Each triangular support plate of the present invention is composed of a short board and a long board, and the angle between the short board and the long board ranges from 50 degrees to 70 degrees; the bottoms of the two short boards are connected by a bayonet, and the bottoms of the two long boards pass through Pin connection; the intersection of the short and long plates of the two triangular support plates is connected by a pin. The device of the invention can effectively improve the safety of the hoisting operation, and can satisfy the long-term high-intensity use, is easy to recover after the device fails, and can effectively reduce the labor intensity of the operators.

Description

technical field [0001] The invention relates to the field of hooks, in particular to an anti-off device for hooks that is easy to install and disassemble. Background technique [0002] The hook anti-off device is widely used on the hooks used in various hoisting work places. It is a device set up to prevent the hanger from slipping off the hook during hoisting operations and causing safety production accidents. Taking off the device can reduce the occurrence of lifting operation accidents. The anti-decoupling device installed on the original crane hook group is generally made of aluminum or steel, and its own strength is insufficient. When lifting large tooling spreaders, bumps and deformations often occur. In order to ensure the safety of hoisting operations, frequent replacement is required, and the replacement rate is high. ;The main vulnerable parts and key parts of the original anti-off device are springs. After the spring fails, it cannot be repaired or the cost perfo...

Problems solved by technology

The anti-decoupling device installed on the original crane hook group is generally made of aluminum or steel, and its own strength is insufficient. When lifting large tooling spreaders, bumps and deformations often occur. In order to ensure the safety of hoisting operations, frequent replacement is required, and the replacement rate is high. ;The main vulnerable parts and key parts of the original anti-off device are springs. After the spring fails, it cannot be repaired or the cost performance of repair is not high. Once the spring fails, the general anti-off device will be declared scrapped; The spring force of the anti-off device used on the hook is relatively large, and the installation requires both hands to operate, and another person is required to cooperate with the operation, which affects work efficiency
