The invention provides a covering type double-flange-plate bolt blind penetrating installation guide structure. The covering type double-flange-plate bolt blind penetrating installation guide structure comprises an upper flange plate, a lower flange plate and fan-shaped wedges, wherein the upper flange plate and the lower flange plate are both provided with bolt holes in a corresponding mode, flange plate bolts are installed in the bolt holes in the lower flange plate, and guide rods are connected to the ends, away from bolt caps, of the flange plate bolts; and the fan-shaped wedges are inserted into the gap between the upper flange plate and the lower flange plate which are connected. According to the covering type double-flange-plate bolt blind penetrating installation guide structure, a towering precious metal tower mast can be lifted without damage, so that the towering precious metal tower mast is safe enough in the lifting process; and horizontal and perpendicular moving, precise installation and one-time in-place of the towering precious metal tower mast under the undamaged condition are achieved, and high-altitude disassembling and assembling of a lifting sling are quick and convenient.
