The invention relates to a steam turbine overhauling device, a rotor hoisting mechanism and a connecting sleeve. The connecting sleeve comprises a sleeving body and a clearing piece, wherein the sleeving body is provided with a sleeving cavity, and the inner wall of the sleeving cavity is provided with an internal thread; and one end of the clearing piece is connected with the sleeving body, and the other end of the clearing piece is provided with a clearing part capable of extending into a threaded groove of a screw rod. A clearing part of the clearing piece extends into the threaded groove of the screw rod, and when the clearing piece moves back and forth in the length direction of the screw rod, the clearing part can clear sundries attached into the threaded groove in advance, so that it is guaranteed that the connecting sleeve can reliably and stably move in the length direction of the screw rod, and transmission faults such as blockage and abnormal sound are avoided.

    本发明涉及一种汽轮机检修装置、转子吊运机构及连接套筒,连接套筒包括套接本体及清除件,其中,所述套接本体设有套接腔,所述套接腔的内壁设有内螺纹;所述清除件的一端与所述套接本体连接,所述清除件的另一端设有能够伸入螺杆的螺纹槽内的清除部。清除件的清除部伸入螺杆的螺纹槽内,当清除件沿螺杆的长度方向往复移动时,清除部能够提前将附着在螺纹槽内的杂物剔除,从而保证连接套筒能够可靠、稳定的沿螺杆的长度方向发生位移,避免出现卡塞、异响等传动故障。
