Abstract

The invention provides a tower lifting appliance. The tower lifting appliance comprises a connecting support and multiple telescopic parts. The multiple telescopic parts are radially arranged at intervals with equal angles, one end of each of the multiple telescopic parts is connected to the connecting support, the other end of one of the multiple telescopic parts hooks a tower flange through a lifting hook, and the other end of each of the rest telescopic parts is fixed to the tower flange. By the adoption of the tower lifting appliance, the roundness of the tower flange can be corrected in the transportation, reshipment and lifting processes, and therefore it is guaranteed that a tower is smoothly installed.

Description

technical field [0001] The present invention relates to the technical field of wind power generation, and more particularly relates to a tower spreader used for correcting the roundness of the tower flange and preventing deformation of the tower flange during the tower transportation, reverse transportation, hoisting and other processes. Background technique [0002] The deformation of the tower flange has always been a prominent problem with the increase in the diameter of the tower. As far as the current tower with a diameter of seven meters is concerned, due to its own weight and long storage period, the deformation of the tower flange is relatively large, and it is difficult to install and connect the tower on site. Once the tower flange is deformed, there will be a huge safety hazard to the hoisting of the whole machine and the operation of the unit. It is extremely necessary to ensure the roundness of the tower flange. Therefore, there is a need for a device for solvi...
