AI Technical Summary

Technical Problem

The existing flipping and hoisting equipment are two separate pieces of equipment, resulting in low efficiency and high cost in the flipping and hoisting process during the production and assembly of large integrated modular houses or prefabricated components.

Method used

Design a tilting and lifting mechanism that combines a lifting frame, lifting components, and tilting components to achieve unified tilting and lifting. The mechanism uses flexible slings and rotating rollers for tilting and utilizes a drive mechanism and a geared motor for automated control.

Benefits of technology

It improves the efficiency of hoisting, transporting and flipping operations of integrated modular houses and large building components, reduces equipment investment costs, and the equipment is lightweight, easy to move and does not occupy a fixed site.

Abstract

An overturning and hoisting mechanism and an overturning and hoisting method, relating to the field of building construction. The overturning and hoisting mechanism comprises a spreader (4), a hoisting assembly and an overturning assembly, wherein the hoisting assembly is fixedly or detachably connected to the spreader (4), and the overturning assembly is fixedly connected to the spreader (4). In the overturning and hoisting method, the overturning and hoisting mechanism is used to overturn and hoist a prefabricated component (1). The overturning and hoisting mechanism can implement overturning or hoisting simply by means of changing slings or ropes connected to objects to be hoisted, thereby improving the efficiency of hoisting transportation and overturning operations on integrated modular houses and large building components, and reducing investment in production equipment. The apparatus features light weight, easy mobility and low costs, and also does not occupy fixed sites.
