Problems solved by technology

As the power and load of the designed unit increase with the capacity of the unit, the diameter of the tower increases accordingly, but the thickness of the tower wall and the width and thickness of the flange do not increase proportionally, which directly leads to the increase of the flange of the tower. There is a risk of hoisting deformation during turning over
In particular, as image 3 As shown, the sliding tail lugs 3 and 4 are generally installed near the top of the first end 103 of the tower. It is very difficult to install and disassemble. risk

Abstract

The invention provides a tower drum overturning device and a tower rack mounting system. The tower drum overturning device is used for overturning a tower drum from a horizontal state to a vertical state, and comprises a tower drum overturning supporting seat; the tower drum overturning supporting seat comprises a first overturning supporting seat and a second overturning supporting seat; each ofthe first overturning supporting seat and the second overturning supporting seat comprises a fixed support and a rotary support; each rotary support comprises a rotary arm and a supporting portion; each rotary arm is rotatably connected with the corresponding fixed support; and a supporting portion is formed on each rotary arm in the radial direction and is used for fixedly supporting a first endof a tower drum. The tower rack mounting system comprises the tower drum overturning device. The tower drum can be overturned from the horizontal state to the vertical state, and deformation of a lower flange of the tower drum in an overturning process is relieved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, more specifically, to a tower turning device and a tower installation system for turning the tower of a wind power generating set. Background technique [0002] During the hoisting of offshore projects, the tower is in a flat state when it is transported from the transport ship to the installation ship. During the installation of the wind turbine, the tower needs to be turned over, that is, the tower is turned from a horizontal state to a vertical state, and then Install again. [0003] figure 1 It is a schematic diagram of the assembly of the tower turning device in the prior art for tower turning. figure 2 yes figure 1 Installed in the Pzizi supporting structure 5 at the lower flange 104 of the tower. image 3 yes figure 1 The left side view of the tower tube stand-over device does not include the Pzizi support structure 5. Such as figure 1 As shown, the existing tower tub...
