SUSPENSION DEVICE FOR WIND WHEEL BLADE, METHOD OF MOUNTING WIND WHEEL BLADE, AND METHOD OF CONSTRUCTING WIND-DRIVEN GENERATOR |
摘要 |
The present invention provides a wind-turbine rotor-blade hoisting apparatus that enables attachment and removal of wind-turbine rotor blades without using a plurality of heavy machines and that enables attachment and removal of wind-turbine rotor blades on a site having a complex land shape with little flat land, a method for attaching a wind-turbine rotor blade, and a method for constructing a wind power generator. The present invention is characterized in that it includes a sheave (14) that guides a hoisting wire (17) from a rotor head (4), to which a wind-turbine rotor blade (6) is to be attached, toward the wind-turbine rotor blade (6) and that is arranged so as to be movable in a direction along the rotation axis of the rotor head (4); a retaining portion (15) that retains an attaching end of the wind-turbine rotor blade (6) such that a line connecting the center of gravity of the wind-turbine rotor blade (6) and a connecting portion, to which the hoisting wire (17) is connected, crosses the longitudinal axis of the wind-turbine rotor blade (6); and a winch (12) that is disposed on the ground and that draws the hoisting wire (17) to wind up or let out the retaining portion (15). |
