The invention provides a wind power blade lifting device which comprises a rack, a lifting frame lifting relative to the rack is arranged on the rack, a supporting frame used for supporting the blade tip of a wind power blade is hinged to the lifting frame through a hinge shaft, and the supporting frame is attached to the outer surface of the blade tip of the wind power blade. The shaft core direction of the hinge shaft is located in the horizontal direction and is perpendicular to the length direction of the wind power blade. When the lifting device is used, the whole lifting device is placed below the blade tip part of the wind power blade, then the lifting frame is started to ascend, the supporting frame is attached to the wind power blade and then ascends continuously, and at the moment, the blade tip part of the wind power blade is lifted to generate certain inclination. At the moment, the supporting frame is attached to the wind power blade and hinged to the lifting frame, so that when the wind power blade inclines, the supporting frame is driven to incline, the supporting frame is kept to be attached to the wind power blade all the time, and the situation that the wind power blade is damaged due to stress concentration caused by linear contact formed by inclining and tilting of the wind power blade relative to the supporting frame is avoided.
本发明提供了一种风电叶片托举装置,包括机架,所述机架上设置有相对机架升降的升降架,所述升降架上通过铰接轴铰接有用于托撑风电叶片叶尖部的托撑架,所述托撑架与风电叶片叶尖部的外表面贴合,所述铰接轴的轴芯方向位于水平方向且垂直于风电叶片的长度方向。先将托举装置总体放置于风电叶片的叶尖部位下方,然后启动升降架使其上升,托撑架与风电叶片贴合,然后持续上升,此时风电叶片的叶尖部位抬起产生一定的倾斜。由于此时托撑架与风电叶片贴合且托撑架与升降架铰接,这样风电叶片倾斜时会带动托撑架倾斜,使托撑架始终保持与风电叶片贴合,避免风电叶片相对托撑架倾斜翘起形成线接触造成应力集中损坏风电叶片。
