Device suitable for balanced hoisting of large and medium-sized space prefabricated unit parts and hoisting method

The invention discloses a device and a hoisting method suitable for balanced hoisting of large and medium-sized space prefabricated unit parts. The device comprises a hoisting frame, a set of lifting lugs are welded to the top of the hoisting frame, a hanging plate is welded to the bottom of the hoisting frame, hanging holes are evenly distributed in the hanging plate, and the hoisting frame hoists a space prefabricated unit through a pulley assembly. A group of hanging rings are arranged at the top of the space prefabrication unit, the pulley assembly comprises a group of pulleys, hooks are connected to the pulleys, the adjacent pulleys are alternately hung on the hanging holes and the hanging rings through the hooks, and an annular steel wire rope is wound on the group of pulleys; chain blocks are connected between the hoisting frame and the four corners of the top of the space prefabrication unit in a one-to-one correspondence manner. According to the invention, all lifting points are uniformly and vertica
