Alignment system and method for hoisting of wind power generating set

Abstract

The invention discloses a lifting and aligning system and method of a wind turbine generator system. The lifting and aligning system of the wind turbine generator system comprises one or more than twoinformation acquiring units and a display unit, wherein the information acquiring units are arranged on a first connecting part of a first lifting structure of the wind turbine generator system for acquiring attribute parameters of one or more than two preset marks and sending the acquired attribute parameters to the display unit; the display unit is used for displaying the attribute parameters and preset standard parameters; and the preset standard parameters represent standard attribute parameters of the preset marks in alignment of a first lifting structure and a second lifting structure.The lifting and aligning system of the wind turbine generator system can improve alignment of an impeller and the lifting efficiency of the wind turbine generator system.

Description

Technical field [0001] The invention relates to the technical field of wind power generation, in particular to a hoisting and alignment system and method for a wind power generating set. Background technique [0002] With the development of wind power technology, the height of wind turbine towers is usually above 80m, and the weight of impellers, generators and other components has also greatly increased. This situation has brought great difficulties to the hoisting work of wind turbines. And challenging. Especially for the hoisting of the impeller in the wind turbine, because the impeller needs to have an angle of about 5° with the vertical direction when hoisting the impeller, it is necessary to align the position of the impeller and the generator first, and then align the position. Carry out the installation operation of the impeller and generator, which puts forward higher requirements on the accuracy of impeller hoisting. [0003] In the traditional impeller hoisting method,...

Problems solved by technology

[0004] However, in the traditional hoisting method, the staff arranged in three directions communicate through walkie-talkies or mobile phones to complete the alignment process of the impeller. Not only the communication efficiency is low, but also information transmission errors are prone to occur during the communication process, which makes it difficult to align the impeller. increase, time-consuming, and reduce the hoisting efficiency of wind turbines
