A hoisting device for the installation of a large wind power generating set

Abstract

The invention relates to a hoisting device used for installing a large-scale wind power generating set. A hoisting device for the installation of a large wind power generating set, the hoisting device includes a chassis, a slewing mechanism, a balance counterweight, a main boom, a hoisting mechanism, a luffing boom, a second hook, a third hook, The wind blade carrier and the stable support device, the hoisting mechanism is arranged on the slewing mechanism, and the hoisting mechanism includes the first load drum, the second load drum, the third load drum and the luffing drum; the luffing boom It includes an acute-angle triangular truss, a first main truss, a second main truss, and a luffing drive device, and the luffing drive device includes a first luffing bracket, a second luffing bracket, a first luffing rod, a second luffing The pull rod and the third luffing rod; the stable support device includes a tension mechanism support base, two lower tension arms and two upper tension arms. The invention comprehensively solves the lifting and hoisting problems of overweight, super high and super large blades of large wind power generators.

Description

technical field [0001] The invention relates to a hoisting device used for installing a large-scale wind power generating set. 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 onshore w...
