Auxiliary dismounting device for water turbine

Provided is a water turbine auxiliary dismounting device. A large amount of manpower and time need to be input in the operation process of an original manual one-dragging-three hydraulic jack for water turbine disassembly, and the three jacks often have the phenomenon of asynchronous lifting and descending, so that a lifted workpiece is inclined, and the danger of disassembly work is increased. The device comprises a seat ring (8), at least three lifting screw rods (3) and at least three supporting screw rods (4) are in threaded connection with the circumferential surface of the bottom of the seat ring, and the lifting screw rods and the supporting screw rods are distributed at intervals; each lifting screw rod is sleeved with a cross-core hydraulic jack (1) and is fixed on the lifting screw rod through a fixing nut (2); and each supporting screw rod is in threaded connection with a limiting nut (7). The device is used for auxiliary disassembly of the water turbine. 水轮机辅助下拆装置。水轮机下拆原使用的手动一拖三液压千斤顶，操作时要需投入大量人力及时
