Tooling device and method for single blade installation of wind power generating set

Abstract

The invention discloses tool equipment and a method for single blade installation of a wind driven generator set. The tool equipment comprises a frame body, a clamping module and a balance module. Compared with the prior art, when the tool equipment, provided by the invention, installs a blade, and when lifting equipment lifts the tool equipment to the mounting end part of the blade to be as high as a variable pitch bearing, the clamping module in the tool equipment only needs to be driven to slide corresponding to the frame body; and in the sliding process of the clamping module, under the effect of the balance module, the total gravity center position of the tool equipment clamped with the blade is not changed, that is, the gesture of the blade is not changed, and an angle between the blade and the horizontal plane is not changed, so that the mounting end part of the blade is always aligned to the variable pitch bearing in the process of the clamping module clamping the blade to slide, and finally, the mounting end part of the blade slides in a guide cover to connect with the variable pitch bearing. The tool equipment is simpler in blade mounting mode, reduces the single blade installation difficulty, and improves the blade installation efficiency.

Description

technical field [0001] The invention relates to the technical field of blade assembly of a wind power generator, in particular to a tooling device and method for installing a single blade of a wind power generator. Background technique [0002] The wind power generating set mainly includes a tower and an impeller installed on the tower. The impeller mainly consists of a hub and blades, and the number of blades is generally three. There are also many ways to install the impeller, and the commonly used installation methods are the overall hoisting method and the single blade hoisting method. [0003] With the increasing capacity of a single wind turbine, it poses great challenges to the transportation and installation of the unit. The single-blade hoisting method has great advantages and has become the main trend of the future development of wind turbines. At present, the single-blade hoisting method mainly adopts horizontal hoisting: firstly, the hub is locked to the horizon...

AI Technical Summary

Problems solved by technology

[0004] Since the gap between the shroud and the blade is very small, only about 5cm, it is very troublesome to assemble in the air, and the requirements for the micro-movement performance of the crane, the hoisting commander and the crane driver are very high

Especially for direct-drive wind turbines, the impeller cannot be cranked, and the impeller cannot be locked in a horizontal position for installation. The hoisting of a single blade of a direct-drive wind turbine can only lock the impeller at a position at an angle of 30 degrees to the ground. At this time, The blade is tilted at 30 degrees, and the docking process of the blade and the blade bearing is a composite motion of horizontal motion and vertical motion, which requires micro-operation of the crane's swing and retraction rod at the same time, which makes installation difficult and the installation efficiency of the blade is correspondingly low
