Cargo falling prevention device for automatic crane and using method thereof

Abstract

The invention discloses a cargo falling prevention device for an automatic crane and a using method thereof. The device comprises two parallel transverse hanging frames, a flat mounting plate, a leftprotecting plate and a right buckling plate, the flat mounting plate is arranged above the middle portion between the two transverse hanging frames, and a cuboid-shaped top buckling plate is arrangedabove the flat mounting plate in parallel. The device has the beneficial effects that two second push clamping blocks clamp and fix the two sides of the upper end of a lifting hook respectively, so that the device, a cable chain and the lifting hook on the crane are clamped and fixed, and the device can conveniently protect cargoes lifted by the crane; and a second hydraulic cylinder pushes firstpush clamping blocks to move to guarantee that the device can be fixedly clamped to cable chains and lifting hooks in different specifications and sizes for work, the four first push clamping blocks are clamped around the cable chain in the circumferential direction, the second push clamping blocks are clamped on the two sides of the lifting hook respectively, it is guaranteed that the device, thecable chain and the lifting hook on the crane are clamped and fixed more firmly, and the device is very convenient and fast to assemble, use or disassemble.

Description

technical field [0001] The invention relates to a cargo drop prevention device, in particular to a cargo drop prevention device for an automatic crane and a method for using the same, belonging to the application technical field of crane protective equipment. Background technique [0002] In the automatic crane, the goods are lifted by the hook at the bottom of the cable chain to move. With the rapid development of the industrial level, more and more anti-cargo drop-off devices are assembled and used on the crane. The anti-cargo drop-off device is sleeved on the cable chain of the crane The bottom and the hook, and when the crane lifts the goods, the goods are protected to prevent the goods from falling. [0003] There are still many deficiencies in the existing anti-cargo fall prevention devices for automatic cranes. The existing anti-cargo fall prevention devices are often welded and fixed with the hooks or chains on the crane, resulting in the anti-cargo drop prevention. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing anti-dropping device is often welded and fixed with the hook or cable chain on the crane, which makes the anti-dropping device inconvenient to be disassembled and maintained from the crane; and the existing The anti-cargo drop device cannot be assembled with chains or hooks of different sizes, and the limitations of the use of the anti-cargo drop device are relatively large; and the firmness of the assembly and fixation of the anti-cargo drop device with the cable chain or hook is poor. The existing anti-dropping device has poor protection performance for the cargo. When the cargo is lifted and moved by the crane, it is easy to shake or even fall. The falling device cannot protect goods of different sizes and heights, and the working range of the anti-cargo falling device is small; the stability of the components on the cargo-falling device is poor when working, and the overall service life of the cargo-falling device To solve the short problem, an automatic crane anti-dropping device and its use method are proposed
