Lifting appliance and method for prefabricated part

Abstract

The invention relates to the technical field of prefabricated parts, in particular to a lifting appliance and method for a prefabricated part. The lifting appliance comprises a bearing steel beam, and lifting mechanisms are arranged at the two ends of the bearing steel beam. Each lifting mechanism comprises a self-locking hook and a lifting steel wire rope, and the self-locking hooks are located on one side of the width direction of the bearing steel beam. The lifting steel wire ropes are arranged between the self-locking hooks and the bearing beam in a tensioning mode, and the bearing steel beam is provided with a tower crane connecting mechanism between the two lifting mechanisms. The tower crane connecting mechanism comprises a lifting ring and a tower crane steel wire rope, the lifting ring is located on the other side of the width direction of the bearing steel beam, the tower crane steel wire rope is arranged between the lifting ring and the bearing steel beam in a tensioning mode, and the self-locking hooks can be clamped and fixed in the lifting ring. The lifting appliance has the following effects that the universality of the lifting appliance is improved, the use of a special lifting appliance is reduced, and the situation that the special lifting appliance is mistakenly used is not prone to occurring when the prefabricated part is lifted.

Description

technical field [0001] The present application relates to the technical field of prefabricated components, in particular to a hoisting sling for prefabricated components and a hoisting method thereof. Background technique [0002] Reinforced concrete structures include cast-in-place integral reinforced concrete structures and prefabricated integral reinforced concrete structures. The prefabricated assembly integral structure is the prefabricated component. The prefabricated component is a structural form in which various reinforced concrete prefabricated components are mechanically installed and assembled according to the design requirements. The production process of prefabricated components includes the production and installation of formwork, the production and installation of steel bars, the preparation and transportation of concrete, the pouring, vibration and maintenance of components, demoulding and stacking, etc. [0003] Prefabricated components are often used in p...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that all kinds of prefabricated components need special hoisting tools to keep the prefabricated components stable during hoisting, and the compatibility between the special hoisting tools is poor. If the special hoisting tools If used incorrectly, it may cause the prefabricated component to slip in the hoisting, or cause a safety accident if it is serious.
