Tower cylinder overturning device and hoisting method for tower cylinder

Abstract

The invention provides a tower cylinder overturning device and a hoisting method for a tower cylinder. The tower cylinder overturning device comprises a base, an overturning bracket and a hydraulic supporting device. One end of the overturning bracket is in pivot connection with the base, and the overturning bracket can be overturned to a horizontal state from a vertical state. The overturning bracket comprises a supporting plate supporting part and a side supporting part. The upper surface of the bracket supporting part is used for supporting the bottom of the tower cylinder in the axial direction, and the side supporting part is used for supporting the side wall of the tower cylinder in the radial direction. According to the tower cylinder overturning device, the bracket supporting part supports the bottom of the tower cylinder, the side supporting part supports the side wall of the tower cylinder, after the tower cylinder overturning device is connected with the bottom of the tower cylinder in a butting manner, by means of the action of a crane, the tower cylinder can be hoisted into the vertical state from the horizontal state, and then the crane hoists and installs the tower cylinder.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a tower turning device and a tower hoisting method for turning over a tower of a wind power generating set. Background technique [0002] The tower of the wind turbine is an important part of the generator set, usually in the shape of a cylinder, which has the characteristics of large diameter, long length, and heavy weight. When installing the generator set, the tower is in a flat state when it is transported to the work site. It is necessary to use a hoisting machine to turn the tower from horizontal to vertical (also called tower turning), and then install it in place. [0003] At present, the traditional tower turning process is completed by the cooperation of two cranes, the crane connected to the upper flange is the main crane, and the crane connected to the lower flange is the auxiliary crane. First, the main and auxiliary cranes lift the tower hor...

AI Technical Summary

Problems solved by technology

[0005] (1) The main and auxiliary cranes and towers occupy a large area of ​​the site;

[0006] (2) The installation of the upper and lower flange spreaders and the disassembly of the lower flange spreaders take a long time and require more labor;

[0007] (3) The cooperative operation of the main and auxiliary cranes requires high coordination accuracy between the two drivers. If the cooperation is not good, great safety risks will occur;
