METHOD FOR HOISTING BLADE OF WIND TURBINE GENERATOR SYSTEM AND DEVICE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method for hoisting a blade of wind turbine generator system maintaining a posture of a frame fixing and holding the blade always horizontal, and a device thereof.;SOLUTION: When a frame body 2 is hoisted by three ropes 21, (22), 23 after fixing and holding the blade B to a blade holding part 3 of the frame body 2, signal from a transmitter held by an operator on the ground is transmitted to an oil controller attached to a cylinder connected to the rope which requires inclination correction to move a piston rod downward by sending oil at a piston front side of the cylinder to a piston rear side if indicating lamps 9, 10 indicating inclination in a fore-and-aft direction and/or a left-and-right direction attached to the frame body 2 are turned on. Length of the rope is substantially extended by the movement of the piston rod, and the frame body 2 is maintained always in the horizontal state.;COPYRIGHT: (C)2011,JPO&INPIT
