Abstract

The invention provides an adjustable offshore large-scale wind power blade hanger and a hoisting method thereof, and relates to a blade hoisting tool and a hoisting method of a large-scale offshore wind power generating set. The hoisting method of the present invention adopts an adjustable offshore large-scale wind power blade sling, which includes a platform, a blade root end clamp, a blade tip clamp, a counterweight, and a swing arm hinged on the upper surface of the platform, and uses the positioning hydraulic cylinder of the sling A pair of lower chucks 1 is used for horizontal positioning control, and positioning hydraulic cylinder 2 is used for horizontal positioning control of lower chuck 2. Clamping hydraulic cylinders 1 and 2 can be used to control the falling of upper chucks 1 and 2 respectively. Adjust the hydraulic cylinder It can control the plumb angle of the blade before it is installed with the impeller, which can meet the adjustment requirements of the blade installation angle. During the whole hoisting process, except for the rubber block 1 and the rubber block 2, other parts of the spreader are not in contact with the blade, and the clamping force can also be determined by The first and second clamping hydraulic cylinders are controlled without damaging the surface of the blade, and the large wind power blades on the sea are reliably hoisted.

Description

technical field

[0001] The invention belongs to the field of hoisting of wind power generators, and in particular relates to a blade hoisting tool of a large offshore wind power generator; the invention also relates to a method for hoisting blades of a large offshore wind power generator. Background technique

[0002] The rapid development of the global economy has led to the gradual depletion of fossil energy, and the global environmental pollution has become increasingly serious. It is an important problem facing the world to seek new renewable and clean energy. Since the last century, wind power energy has gradually gained attention in various countries, and the wind power industry has developed rapidly, becoming the most important source of electric energy besides fossil energy. However, in recent years, the land resources that can be developed have been continuously decreasing, making it difficult for the land wind power generation business to maintain the supply of ele...
