Abstract: A lifting mechanism includes a lifting beam, a hanging portion suspended below the lifting beam and including a hanging base, a hanging chain, a movable sprocket disposed on the hanging base, a distance adjusting sprocket, and a power mechanism. The distance adjusting sprocket and the power mechanism are arranged side by side and separately on the lifting beam. The power mechanism includes a fixed sprocket and a driving portion. The fixed sprocket is driven by the driving portion to drive the hanging chain to move, so as to lift or lower the hanging portion. An end of the hanging chain is fixed to the lifting beam, and the other end of the hanging chain engages the movable sprocket, the fixed sprocket, and the distance adjusting sprocket, or the other end of the hanging chain engages the movable sprocket, the distance adjusting sprocket, and the fixed sprocket.

Abstract: A vertical lifting device and method are provided. The vertical lifting device includes a fixed frame fixed to a foundation. A first cavity allowing passage of a lifting rope is provided in the middle of the fixed frame. A sliding frame moving horizontally on the fixed frame is arranged above the fixed frame. A second cavity allowing passage of the lifting rope is provided in the middle of the sliding frame. At least two stepping vehicles alternately lowering or lifting weights are arranged on the sliding frame and move on the sliding frame. The stepping vehicles are spaced in preset distances. The lifting rope penetrates through the stepping vehicles in sequence. Each stepping vehicle is provided with a clamping part clamping the lifting rope and a driving mechanism driving the stepping vehicle to move on the sliding frame.
