Wind generator tower and lifting method thereof

Abstract

The invention discloses a wind generator tower and a lifting method thereof. The invention relates to a combined tower of a wind generator and the lifting method thereof, in particular to a hinged support type tower and the lifting method thereof. The invention provides the wind generator tower which adopts an ordinary lifting device with a certain lifting force and utilizes the multi-stage operation way for realizing the large-stroke staged operation and the lifting method thereof. The wind generator tower comprises a base fixed on the ground and the tower hinged with the base, wherein the tower can carry out the motion from the horizontal state to the vertical state relative to the base through the lifting device. The wind generator tower changes the mode of fixedly arranging a lifting oil cylinder in the past, adopts the lifting device and a support which can move the positions, and realizes the lifting of the large tower through the staged elongation of the lifting device. The lifting device can adopt a smaller hydraulic cylinder, an electro-hydraulic push rod, a mechanical jack and the like, thereby facilitating the carrying, simplifying the operation and reducing the mounting cost. The safety is high and the labor intensity is small during the lifting operation.

Description

technical field [0001] The invention relates to a combined tower of a wind power generator and a lifting method thereof, in particular to a hinged tower and a lifting method thereof. Background technique [0002] The installation of wind turbine towers is an important part of installing wind turbines. The conventional method is to use cranes, which is expensive, time-consuming and labor-intensive. The hydraulic lifting tower can realize the automatic lifting of the tower, and the ordinary hydraulic lifting tower is limited by the stroke of the oil cylinder due to the use of a fixed position oil cylinder, which cannot lift the tower over 16 meters and the wind power over 1000 kg. machine. If a large-stroke, large-scale oil cylinder or lifting device is used to lift the tower of a large-scale wind turbine at one time, on the one hand, the transportation is not easy, and the conditions of the installation point cannot meet the requirements of using these large-scale equipment....
