Device for jacking and falling ultra-large weight at high altitude

An upper lifting supporting frame is installed above a lower fixing frame, a lower supporting column is fixed to the top of a stand column of the lower fixing frame, and a lower supporting plate is installed at the top of the lower supporting column; the upper lifting supporting frame is of a frame structure matched with the structure of the lower fixing frame, lower supporting columns are fixed through connecting rods between stand columns of the upper lifting supporting frame, the lower end of an upper supporting plate is fixedly connected with an anchoring end, and a weight supporting plate is installed at the top of the upper lifting supporting frame. After the lower fixing support is fixed, the upper lifting supporting frame can move up and down along the guide sliding mechanism. The device has the advantages that the whole device falls to a preset height and is installed in place, the motion posture stress distribution of a heavy object can be controlled, long-term retention at high altitude and fine ad
