Embodiment Construction

[0019] reference figure 1 with figure 2 , figure 1 It is a schematic diagram of the spreader device provided on the blade according to the first embodiment of the present invention; figure 2 It is a schematic diagram of the spreader device provided by the first embodiment of the present invention during the installation process.

[0020] Such as figure 1 with figure 2 As shown, in this embodiment, the spreader device includes a hanger 2, a plurality of first studs 4, and a plurality of second studs 5; both ends of the hanger 2 are provided with threaded holes 11 at the root of the blade 1. The corresponding stud mounting hole 221. The second stud 5 is used to connect the variable pitch bearing 7 and the blade 1 and can form a space for accommodating the hanger 2 between the variable pitch bearing 7 and the blade 1. The length of the second stud 5 may be greater than that of the blade mounting stud. Length; the first stud 4 is used to connect the hanger 2 and the blade 1. The l...

Abstract

The invention provides a blade hanger device of a wind turbine generator. The blade hanger device comprises a hanging bracket, a plurality of first studs and a plurality of second studs, wherein the two ends of the hanging bracket are provided with stud mounting holes corresponding to thread holes in the root of a blade; the second studs are used for connecting a variable paddle bearing and the blade and can form a space for containing the hanging bracket between the variable paddle bearing and the blade; and the first studs are used for connecting the hanging bracket with the blade. According to the blade hanger device of the wind turbine generator, provided by the invention, a blade mounting stud is replaced through the second studs, and the hanger device is mounted in the thread holes of the blade through the first studs; an existing structure of the blade is sufficiently utilized to mount and dismount the blade; and the structure of the blade does not need to be changed, the dismounting efficiency is high and the maintenance cost is low.

Description

Technical field [0001] The invention relates to a wind turbine blade hoisting technology, in particular to a wind turbine blade sling device. Background technique [0002] With the rapid development of wind power technology, wind power technology and wind turbine performance have been gradually improved and improved, wind turbines have become more and more economical and efficient, and the single-unit capacity of wind turbines has also been increasing. [0003] With the gradual increase in the single-unit capacity of wind turbines, the weight of the wind turbines has gradually increased, correspondingly increasing the difficulty of maintaining various components of the wind turbines and increasing maintenance costs. In view of the difficulty and high maintenance cost of wind turbines, many high-power wind turbines are equipped with maintenance cranes. The maintenance crane that comes with the wind turbine can be used to maintain and replace most of the large components of the wind...
