Self-balance hoisting tool and hoisting method for specially-shaped component

Abstract

The invention provides a self-balance hoisting tool and a hoisting method for a specially-shaped component, belongs to the technical field of building construction, and aims to solve the problems that two cranes are required to hoist the specially-shaped component and hoisting points are required to be replaced in the prior art. The self-balance hoisting tool for the specially-shaped component comprises a hoisting hook, a hoisting beam and two pulley blocks, wherein a hoisting lug is arranged at each of the two ends of the hoisting beam and is connected with the hoisting hook through a steel wire rope; each pulley block comprises a first fixed pulley, two second fixed pulleys and a cable; each first fixed pulley is connected with the corresponding hoisting lug through the steel wire rope; in each pulley block, one end of the cable sequentially penetrates through one of the second fixed pulleys, the first fixed pulley and the other second fixed pulley; a hoisting ring is arranged at each of the two ends of each cable. According to the self-balance hoisting tool and hoisting method, the hoisting period can be effectively shortened, and the hoisting cost is reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a self-balancing hoist and hoisting method for special-shaped components. Background technique [0002] In the ever-growing field of steel component installation, the types of hoisting components have become huge and diverse, and the hoisting components are usually irregular shapes. Such components have the characteristics of complex switching conditions and various hoisting conditions during the installation process. How to choose a reasonable and safe component lifting technical route during the installation process to avoid damage to components during the component lifting project is a difficult point in lifting technology. [0003] Especially for large-scale special-shaped components, after the assembly is completed on the site frame, two cranes are usually required to lift the assembled components off the ground as a whole, and then replace the lifting points, ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a self-balancing hoisting device and hoisting method for special-shaped components to solve the problems of long installation period and high installation cost caused by the need for two cranes to replace the hoisting points in the prior art. The hoisting beam enables the special-shaped components to be adjusted to the hoisting position without replacing the lifting point and straightening the lifting board after hoisting, which reduces the number of hoisting steps and the demand for large cranes, thereby shortening the installation cycle and reducing installation costs. the goal of
