fifthly, the connecting piece (11) penetrates through the limiting block (31), and the distance between the backing plates (1) is limited by connecting the connecting piece (11) end to end by adjusting the backing plates (1) to the required positions;
sixthly, fixing all the first winches (9) on the base plates (1) respectively, fixing the second winch (8) on any one base plate (1), and then connecting the first rope (6) with the second winch (8) in a winding manner, and connecting the second rope (10) with the first winch (9) in a winding manner to complete the erection of the whole device;
hoisting the steel structure embedded part to be installed to an installation position by using a crane;
step eight, the first pulley block (5) is lowered to the position near the steel structure embedded part by adjusting a second winch (8) and a first winch (9), and the steel structure embedded part is hoisted at a bottom hook of the first pulley block (5) through a hoisting belt;
step nine, hoisting the steel structure embedded part to a natural state by simultaneously adjusting the second hoisting machine (8) and the first hoisting machine (9), and primarily judging the installation of the steel structure embedded part at a position 100-200mm away from the ground;
and step ten, adjusting the first winch (9) and the second winch (8) simultaneously to enable the steel structure embedded part to fall to a required installation position at a constant speed according to the preliminarily judged position.
