Heavy short shaft hoisting turnover tool and hoisting method

The invention discloses a heavy short shaft hoisting turnover tool and a hoisting method.The tool comprises a pair of arc-shaped hoisting frames, an arc-shaped middle connecting plate, a hoisting screw and an opening positioning screw, and the two ends of the arc-shaped middle connecting plate are hinged to the middles of one sides of the arc-shaped hoisting frames correspondingly; and a middle locking lug and an edge locking lug are respectively arranged on an arc-shaped flange at one end of the arc-shaped lifting frame. The arc-shaped lifting frame and the arc-shaped middle connecting plate with the same curvature of the inner edge arc-shaped surfaces are respectively matched with the outer diameter of the heavy short shaft; and the distance A between the inner side surfaces of the arc-shaped flanges at the two ends of the arc-shaped lifting frame is matched with the length of the heavy short shaft. The method comprises the steps that (1) the pair of arc-shaped hoisting frames wrap the heavy short shaft and
