An automatic crane anti-dropping device and its application method

Abstract

The invention discloses an automatic crane anti-dropping device and a method for using the device, which comprises two horizontal hanging frames arranged in parallel, a flat-mounted plate, a left protective plate and a right buckle plate, and the upper part of the middle part between the two horizontal hanging frames is arranged There is a flat-mounted board, and a cuboid-shaped top gusset is arranged parallel to the top of the flat-mounted board. The beneficial effects of the present invention are: the two second push clamping blocks respectively clamp and fix the two sides of the upper end of the hook, so that the device is clamped and fixed with the cable chain and the hook on the crane, which facilitates the lifting of the crane by the device. Cargo protection work, through the second hydraulic cylinder to promote the movement of the first push clamp block, to ensure that the device can be fixed and clamped on the chains and hooks of different sizes to work, the four first push clamp blocks circumferentially surround the cable It is clamped around the chain, and the second push clamp block is clamped on both sides of the hook respectively, so as to ensure that the clamping and fixing of the device with the cable chain and the hook on the crane is more secure, and the device can be installed, used or disassembled Very convenient and fast.

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
