Split rotating embedment type complete lifting tool and lifting method

Abstract

The invention provides a split rotating embedment type complete lifting tool and a lifting method. The split rotating embedment type complete lifting tool comprises an outer sleeve part, a reset pin and an embedment lifting ring. A hollow portion is arranged inside the outer sleeve part, and a lifting bolt can be embedded into the hollow portion when the assembly operation is conducted. A concaveopening is formed in the top of the outer sleeve part, and the reset pin is arranged in the concave opening. The outer sleeve part is embedded into the embedment lifting ring in a fastened mode. The split rotating embedment type complete lifting tool is light and simple, guarantees the connection fastening performance, is high in bearing capacity and has the high applicability for different typesof buried parts. The stress of a lifted object can be uniform in the using process, and the stability in the mold release lifting process is guaranteed. The lifted object and a hoisting machine are reliably connected, and therefore the potential safety quality hazard which exists due to the fact that a wind tower shakes in the lifting process is avoided.

Description

technical field [0001] The invention relates to a hoisting tool, in particular to a split rotary nesting complete set of hoisting tool and a hoisting method. Background technique [0002] The wind power prestressed concrete tower is the tower pole of wind power generation. It mainly plays a supporting role in the wind power generating set. The wind power concrete tower is generally divided into several sections, and the sections are fixed by connectors. The concrete straight towers used for wind turbine towers are generally designed to have a height of less than 30 meters. For towers above 30 meters, variable-diameter concrete towers are generally used, which is difficult to hoist and requires high precision. [0003] At present, the tooling for hooking objects set on the lifting equipment of the concrete tower ring is usually a hook, and the hook is connected with the object to be lifted by a lifting rope, and then the object to be lifted can be shifted, such as: Lifting, ...

AI Technical Summary

Problems solved by technology

However, the way that the hook is connected to the object to be lifted by a rope cannot satisfy the hooking of all objects. For example, it is very inconvenient to bind and untie the rope for lifting large-diameter and high-tube objects manually.

Its disadvantages are: cumbersome operation, time-consuming, high production cost

Moreover, for the lifting of prefabricated components, the existing lifting gear cannot well adapt to the notch where the lifting nail is located, and the firmness is unstable, and it is easy to collide with the prefabricated concrete ring. The lifting process may cause accidental injury to the product and affect the quality of the lifting. Accuracy and stability of the tower
