The hoisting assembly includes a connecting block, a sliding rod, two steel ropes, two sets of pulley groups and two sets of winches. The connecting block is fixedly installed in the middle of the top of the mounting frame, and a sliding groove is provided on the connecting block. The sliding rod is slidably connected to the sliding groove, and the two ends of the sliding rod are respectively connected to one end of the two steel ropes, and the two sets of pulley groups are symmetrically arranged on both sides of the connecting block. Hooks for fixing heavy objects are installed on the pulley group, and the other ends of the two steel ropes pass through the two sets of pulley groups and are connected to the winches.
