Anti-fall structure and lifting device

Abstract

The invention discloses an anti-falling structure and a lifting device. The anti-falling structure comprises a main welding piece, a clamping piece, a chain and an elastic piece; the main welding piece comprises a fixed frame and a connecting frame which is arranged in the fixed frame; a through groove is formed in the connecting frame; the clamping piece is rotatably connected with the connecting frame; clamping blocks are respectively arranged on the two sides of the clamping piece; the chain is rotatably connected to the clamping piece and penetrates through the through groove; the two ends of the elastic piece are respectively connected with the fixed frame and the chain. According to the anti-falling structure and the lifting device provided by the invention, the chain is arranged on the anti-falling structure, and the anti-falling structure is tensioned or loosened by utilizing the stress of the chain, so that the clamping blocks on the anti-falling structure move relative to the chain under the acting force of the chain. Therefore, when the anti-falling structure is applied to the lifting device, the clamping blocks can be controlled to be separated from or connected with the lifting device by utilizing the tensioning or loosening of the chain, and an effect of preventing a loaded object on the lifting device from falling is achieved.

Description

technical field [0001] The invention relates to the field of lifting devices, in particular to a fall prevention structure and a lifting device. Background technique [0002] With the soaring real estate prices and the popularity of family cars, the problem of difficult and expensive parking has always been the most troublesome thing for car owners. The resulting traffic jams, random parking, and static traffic problems caused by this have become global modern urban problems. [0003] In order to solve the problem of parking spaces, a multi-storey lifting and traversing parking equipment has been developed. At present, the general-purpose multi-storey lifting and traversing parking equipment is usually equipped with a fall prevention device, which is used to prevent the vehicle from falling due to accidental weight loss or failure of the lifting device during the lifting process. [0004] However, these anti-fall devices are usually large in size and complex in structure, ...

AI Technical Summary

Problems solved by technology

[0004] However, these anti-fall devices are usually large in size and complex in structure, occupy a large space and are not easy to install; in addition, the existing anti-fall devices are not stable enough in working state, so it is not easy for operators to control, so it is impossible to ensure multi-layer lifting Safety and reliability of parking equipment
