Embodiment Construction

[0044] Embodiments of the invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. Although the hub and the pitch bearing of the wind power generating set will be described below as an example, the scope of application of the misalignment correction device according to the present invention is not limited thereto, and it can be applied to various occasions requiring misalignment correction without Limited to wind power field or misalignment correction between hub and pitch bearing. In addition, the device for correcting misaligned holes according to the present invention can be used not only for hole correction and alignment during equipment assembly, but also for hole misalignment that occurs after the equipment has been in operation for a period of time.

[0045] The following will refer to Figure 1 to Figure 8 The specific configuration of the misalignment correction device a...

Abstract

The invention provides staggered hole correcting equipment and a staggered hole correcting method. The staggered hole correcting equipment comprises a correcting device. The correcting device comprises a correcting rod and a correcting sleeve. The correcting rod comprises a large-diameter part, a small-diameter part and a frustum part located between the large-diameter part and the small-diameterpart. The correcting sleeve can sleeve the correcting rod, and the minimum inner diameter of the correcting sleeve is larger than the outer diameter of the small-diameter part. The correcting sleeve is provided with an inner cone part corresponding to the frustum part. The inner cone part makes contact with the frustum part and can apply thrust to the frustum part, and the taper of the frustum part is different from that of the inner cone part. According to the staggered hole correcting equipment and the staggered hole correcting method, the staggered hole correcting efficiency can be improved, the correcting precision can be improved, errors can be reduced, and the safety risk can be reduced. In addition, an overall clamping structure is adopted, damage caused by bolt connection can be avoided, and the reliability can be improved.

Description

technical field [0001] The invention relates to a device for correcting a wrong hole and a method for correcting a wrong hole. Background technique [0002] In wind turbines, during installation and use, there may be wrong holes between the connecting holes between the pitch bearing and the blades and the connecting holes between the pitch bearing and the hub, and the direct result is that the connecting bolts break. [0003] The known method of correcting the misaligned hole is to use a jack and a square to adjust the misalignment of the pitch bearing. However, in such a method, there are disadvantages that the force point of the jack is not firm, the adjustment is inaccurate, and it is time-consuming and labor-intensive. Contents of the invention [0004] In order to solve the above-mentioned problems that the application point of the wrong hole correction is not firm, the adjustment is not accurate, and it takes time and effort, the present invention provides a wrong ho...
