Embodiment Construction

[0064]In the following, the present invention will be more clearly and completely described by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the described embodiments.

[0065] Such as Figure 1-Figure 4 As shown, the present invention discloses a method for hoisting blades of a wind-driven generator. In a wind-driven generator, components such as a nacelle, a generator, and a hub 2 are installed on the upper end of a tower 1. In a preferred embodiment, the above-mentioned components After assembly, use the gondola 60 to hoist as a whole to the upper end of the tower 1 . The hub 2 of the wind power generator has multiple blade installation interfaces, the interface for installing the hanging beam tooling 4 is called the first blade installation interface 21 , and the remaining blade installation interfaces are collectively called the second blade installation interface 22 . Wherein, the first blade i...

Abstract

The invention discloses a wind driven generator and a method for hoisting blades thereof. The method comprises the following steps: S1, mounting a hanging beam tool on a first blade mounting interfaceof a hub; S2, lifting the hanging beam tool, and rotating the hub to enable second blade mounting interfaces to be at corresponding mounting positions; S3, mounting blades on the second blade mounting interfaces; S4, repeating the steps S2 and S3 until the blades are mounted on all the second blade mounting interfaces; S5, lifting the hanging beam tool, rotating the hub to enable the first blademounting interface to be in a dismounting position, and dismounting the hanging beam tool; and S6, mounting blades on the first blade mounting interface. According to the hoisting method, the hangingbeam tool is utilized, the hub is rotated by controlling the hanging beam tool, so that the blade mounting interfaces to be mounted are rotated to better mounting positions, the operation height of hoisting equipment is reduced, and the economic benefit is improved.

Description

technical field [0001] The invention relates to a hoisting method of a wind power generator and blades thereof. Background technique [0002] The blade hoisting of large wind turbines is an important link in the installation of wind turbines. However, blade hoisting has problems such as heavy blade weight, high hoisting height, many lifting equipment used, and difficult coordination. Therefore, how to install blades conveniently and quickly is the focus of R&D and design personnel. [0003] At present, in the installation process of wind turbine blades, in order to facilitate the installation of blades, the generator needs to be rotated. The common method is to add an additional turning device and hydraulic drive device to the generator. The turning device is set according to the weight of the blades. The larger the blade, the larger the turning device, and the corresponding increase in the production cost and weight of the generator. If the generator does not rotate, high...
