DISASSEMBLY AND ASSEMBLY DEVICE ASSISTED BY A WATER TURBINE

The dismantling device assisted by a water turbine. The manual hydraulic jacks used for dismantling under the water turbine previously required a large amount of manpower and time to operate. The three jacks often showed asynchronous lifting and lowering, causing the lifted object to tilt and increasing the danger of the dismantling work. This utility model comprises a seat ring (8), at least three lifting screws (3) and at least three support screws (4) threaded to the bottom circumferential surface of the seat ring. The lifting screws and support screws are distributed at intervals. Each lifting screw is fitted with a through-hole hydraulic jack (1) and fixed on the lifting screw by a fixing nut (2). Each support screw is threaded with a limited nut (7). This utility model is used for dismantling under the assistance of water turbines.
