Abstract
This application discloses a hoisting device for coal mine machinery maintenance, comprising: a movable base, a load-bearing shell, a hydraulic support rod, a crossbeam, a primary rotating assembly, a secondary rotating assembly, a lifting assembly, and a hoisting assembly. The movable base is placed on the ground, the load-bearing shell is fixedly mounted on the upper end of the movable base, the hydraulic support rod is fixedly mounted on the upper end of the load-bearing shell, one end of the crossbeam is rotatably mounted on the upper end of the hydraulic support rod, and the other end is fitted with a connecting frame. The crossbeam and the connecting frame are rotatably connected by a hinge. A placement groove is provided at the end of the crossbeam near the connecting frame. The primary rotating assembly is rotatably mounted on the upper end of the hydraulic support rod, the secondary rotating assembly is rotatably mounted on the end of the crossbeam near the connecting frame, the lifting assembly is rotatably mounted on one side of the connecting frame, and the hoisting assembly is sequentially fixedly mounted on the upper ends of the rotating assembly and the lifting assembly. This application effectively solves the problem that hoisting devices for coal mine machinery maintenance are difficult to adapt to different maintenance needs.
