Embodiment 1

[0019] Embodiment one, such as Figure 1-3 As shown, a blade adjustment and hoisting device for a wind power generator includes two blade clamps 1 and a tower top bracket 2, the two blade clamps 1 are respectively fixed and installed on both sides of the center of gravity of the fan blade, and the two blade clamps The two sides of 1 are connected by fixed rod 3, and fixed rod 3 is arranged parallel to the axis of the blade, and external gear disc 5 is movably connected to fixed rod 3 through rotating shaft 4, and the outer surface of external gear disc 5 is provided with The inner ring gear 6 and the outer gear disc 5 are deviated from the axis to be provided with an outer gear 7, the outer gear ring of the outer gear 7 meshes with the inner gear ring of the outer gear disc 5, and the central axis of the outer gear 7 is connected to the driving end of the rotating motor 8 Transmission connection, the rotating motor 8 is fixedly installed on one end of the mounting frame 9, and...

Embodiment 2

[0021] Embodiment 2, based on the further improvement of Embodiment 1, is to ensure that the position of the axis of the external gear disc 5 coincides with the center of gravity of the fan blades. Therefore, during hoisting, the fan blades can be hoisted more stably without inclination, and when the outer gear disc 5 is driven to rotate by the outer gear 7, a certain power loss can also be reduced.

Embodiment 3

[0022] In the third embodiment, based on the further improvement of the first embodiment, the outer surface of the external gear plate 5 is fixedly connected with the suspension ring 15 , and the other end of the wire rope 14 is fixedly connected with the suspension ring 15 . When hoisting, the end of the wire rope 14 is directly connected to the suspension ring 15 and gets final product.

Abstract

A blade adjusting and hoisting device for a wind driven generator comprises two blade clamps and a tower top support, the two blade clamps are connected through fixing rods, outer gear discs are movably connected to the fixing rods, inner gear rings are arranged on the outer surfaces of the outer gear discs along the edge positions, and outer gears are arranged on the outer gear discs and deviate from the axis. An outer gear ring of the outer gear is meshed with an inner gear ring of the outer gear disc, a center shaft of the outer gear is in transmission connection with the driving end of the rotating motor, and the rotating motor is installed on the fixing rod through an installation frame. A movable guide rail is installed on the upper surface of the tower top support, sliding blocks are slidably connected into the movable guide rail, a telescopic motor is fixedly installed at the end of the movable guide rail, the telescopic end of the telescopic motor is fixedly connected with one sliding block, an elevator is fixedly installed on the sliding blocks, and the driving end of the elevator is connected to the outer gear disc through a steel wire rope. The defects in the prior art are overcome, large hoisting equipment is not needed in the whole process, and the blade replacement cost is greatly saved.

Description

technical field [0001] The invention relates to the technical field of fan blade hoisting, in particular to a blade adjustment and hoisting device for a wind power generator. Background technique [0002] With the increasing development of offshore wind power, the market demand for the replacement and maintenance of large components of offshore wind turbines has also increased sharply. Since offshore wind power is far away from land, "difficulty in replacing large components" has become a common problem faced by global offshore wind power. [0003] The replacement of large parts at sea is usually done using a lifting vessel with outriggers. According to research, in my country, the cost of leasing outrigger hoisting ships is about 3 million yuan for each major component replacement of offshore wind turbines. At present, the insufficient number of domestic outrigger ships and the high cost of use have become the bottleneck for cost reduction of offshore wind turbine compone...
