The invention relates to the technical field of wind power boosting, and particularly discloses a wind power boosting rotor inner tower lifting device which comprises a bottom plate, a connecting beam and a plurality of lifting lugs, a plurality of first matching holes are formed in the bottom plate, and a plurality of second matching holes are formed in the connecting beam; the circumference where the plurality of first matching holes are distributed is the same as the circumference where the plurality of first mounting holes in the mounting flange of the rotor inner tower are distributed, the plurality of first matching holes and the plurality of first mounting holes can be aligned one by one, the connecting beam is connected with the bottom plate, and the plurality of lifting lugs are mounted on the connecting beam. During lifting, a first bolt can penetrate through the first mounting hole and the first matching hole and is connected with a first nut, so that the bottom plate and the mounting flange can be quickly disassembled and assembled, the structural strength of the mounting flange is not influenced, the mounting flange is safe and reliable, and the lifting lug can be positioned at one axial end of the rotor inner tower, so that the radial space of the rotor inner tower is not influenced. And lifting lugs do not need to be welded on the periphery of the rotor inner tower, and assembly of the rotor inner tower and the outer cylinder is not affected.

    本发明涉及风力助推技术领域,具体公开了一种风力助推转子内塔起吊装置,该风力助推转子内塔起吊装置包括底板、连接梁和多个吊耳,底板上设有多个第一配合孔,多个第一配合孔所分布的圆周与转子内塔的安装法兰上的多个第一安装孔所分布的圆周相同,且多个第一配合孔与多个第一安装孔能够一一对齐,连接梁与底板连接,多个吊耳安装于连接梁。起吊时,可通过第一螺栓穿过第一安装孔和第一配合孔并和第一螺母连接,实现底板和安装法兰的快捷拆装,并且不会影响安装法兰的结构强度,安全可靠,吊耳可位于转子内塔轴向的一端,从而不影响转子内塔径向上的空间,相比现有技术,无需在转子内塔的外周焊接吊耳,不会影响转子内塔和外筒的装配。
