The invention discloses a turning-over method, a turning-over structure and a turning-over device for large-scale equipment. The turning-over structure comprises rotating shafts and the turning-over device, wherein the rotating shafts are arranged on the two sides of the large-scale equipment; the turning-over device is arranged at the bottom of a shield body and is used for supporting the rotating shafts; the turning-over device comprises two supports which are positioned below the rotating shafts on the two sides of the large-scale equipment; U-shaped bases are arranged on the tops of the two supports; the two U-shaped bases are coaxial, are matched with the rotating shafts on the two sides of the large-scale equipment and are used for supporting the two rotating shafts; and the rotating shafts can rotate on the two supports. The large-scale equipment is turned over by the following steps of: placing the rotating shafts on the two sides of the large-scale equipment on the U-shaped bases on the two sides of the turning-over device; lifting one side of the large-scale equipment slightly by using a crane; putting down the large-scale equipment after taking a supporting rod out of the bottom; lifting the other side of the large-scale equipment by using the crane; putting down the large-scale equipment again after taking the supporting rod out, so that the bottom of the equipment is hung in the air, is placed on the U-shaped bases on the two sides of the turning-over device through the rotating shafts on the two sides of the large-scale equipment, and is supported by the two supports of the turning-over device; and rotating the large-scale equipment around the rotating shafts so as to turn over the large-scale equipment. The large-scale equipment is turned over conveniently and quickly.

The invention discloses a turnover device and method used for single crane hoisting of prefabricated stand pillars. The device comprises a roadbed box detachably installed on the horizontal plane and turnover mechanisms installed on the roadbed box. In the single crane hoisting process of the prefabricated stand pillars, the ends, away from the hoisting point, of the prefabricated stand pillars are connected to the turnover mechanisms; the turnover mechanisms provide supporting points for the single crane hoisting turnover of the prefabricated stand pillars. By means of the scheme, the defects that the cost is high, pillar legs are prone to being destroyed and safety is poor in the prior art can be overcome, and the beneficial effects of reducing the cost, protecting the pillar legs and improving safety can be achieved.
