Hoisting device for assembling fan blades of large-size wind driven generator

Abstract

The invention relates to a hoisting device for assembling fan blades of a large-size wind driven generator. According to the hoisting device for assembling the fan blades of the large-size wind drivengenerator, the hoisting device comprises a base plate, a rotation mechanism, a balance counterweight device, a winching mechanism, a main cargo boom and an amplitude-changing hoisting arm, wherein the amplitude-changing hoisting arm is arranged above the main cargo boom; a third lifting hook mounting seat is fixedly arranged at the top of the amplitude-changing hoisting arm; a third lifting hookis arranged on the third lifting hook mounting seat; the third lifting hook is connected with a third loading winding barrel on the winching mechanism through a third steel cable; a fan blade loadingdevice is connected with the third lifting hook; the fan blade loading device comprises a first belt type hoisting rope, a first bolt, a second bolt, a third bolt, a fourth bolt, a fifth bolt, a firstlifting lug, a second lifting lug, a third lifting lug, a chain plate, a second belt type hoisting rope, a suspension rod, a fan blade supporting plate and a T-shaped frame. The fan blade loading device adopted by the device has the characteristic of good stability and the hoisting difficulty of the fan blades of the large-size wind driven generator is solved.

Description

technical field [0001] The invention relates to a hoisting device used for assembling blades of a large-scale wind power generator. Background technique [0002] Wind power refers to converting the kinetic energy of wind into electrical energy. Wind is a non-polluting energy source. Using wind power to generate electricity is very environmentally friendly and can generate huge amounts of electricity. Therefore, more and more countries pay more attention to wind power generation. As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×10^9MW, of which the usable wind energy is 2×10^7MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. [0003] my country is rich in wind energy resources, and the wind energy reserves that can be developed and utilized are about 1 billion kW. Among them, the onsh...
