At the construction site of water conservancy projects, the installation of prefabricated parts requires the use of a winch to lift the prefabricated parts from a low position to a high position for installation; the existing water conservancy construction winch consists of a motor, a transmission group, a drum, and a steel wire rope wrapped around the drum. The two sides of the drum are supported by brackets, and bearings are installed between the drum center axis and the bracket to support the rotation of the drum relative to the bracket. After the drum has experienced a long period of load work, the bearing is prone to abnormal noise, leakage and other faults.

The movable plate 13 drives the roller 5 to move to the top of the bottom plate 9 through the second fixed frame 7, until the side of the roller 5 away from the rotating shaft 4 is inserted into the slot 101 in the side plate 10, and then the hydraulic telescopic rod 94 is controlled to extend. The hydraulic telescopic rod 94 pushes the bottom plate 9 to rotate upward around the pin 11 through the ring 93, and the bottom plate 9 drives the side plate 10 to rotate. At the same time, the bottom plate 9 drives the roller 5 to flip through the movable plate 13, so that the roller 5 is flipped from a horizontal state to a vertical state. The roller 5 is placed upright on the upper surface of the side plate 10, and the roller bearing 52 to be repaired is on the upper surface of the roller 5, which is convenient for the staff to observe After the overhaul is completed, the hydraulic telescopic rod 94 is retracted, pulling the bottom plate 9 and the side plate 10 to rotate and reset around the pin shaft 11, and the bottom plate 9 drives the drum 5 to flip and reset, and the rodless cylinder 92 drives the movable plate 13 to insert the prism 81, driving the drum 5 to reset.
