Referring to fig. 1, a hoisting device for a wind-resistant ring of a large storage tank comprises a movable member 11, a rotating shaft 22 and a fixed member 33.

Wherein, the moving part 1 comprises a clamping end 11 and a lifting end 12. The movable member 1 may be a rod member or a plate member, and may be a lever that rotates around the axis of the rotating shaft 2, which is not limited in the present disclosure with respect to its specific shape. One end of the movable part 1 is a hoisting end 12 which is used for being matched with a lifting hook of a crane so as to hoist the whole hoisting device. The other end of the movable member 1 is a clamping end 11, and the clamping end 11 can be configured as a hook for being tightly attached to the vertical surface of the wind-resistant ring 10.

The rotating shaft 2 is fixedly connected to the side wall of the moving member 1, and the rotating shaft 2 is located between the clamping end 11 and the hoisting end 12. The axis of the rotating shaft 2 is the rotating center of the movable piece 1.

The fixing member 3 has an oblong hole 31, and the rotating shaft 2 is disposed in the oblong hole 31 and can move in the oblong hole 31 along the width direction of the wind-resistant ring relative to the fixing member 3. Wherein the clamping end 11 and the fixing piece 3 define a wind-resistant ring fixing groove together. When in use, the wind-resistant ring 10 is directly fixed in the wind-resistant ring fixing groove.

The wind-resistant hoop 10 is then hoisted by connecting the hoisting end 12 by a crane or hoist. In the process of lifting by crane, under the action of gravity, rotation axis 2 can remove a segment displacement to the one end that is close to lift by crane end 12 of slotted hole 31 for lift by crane end 12 and be higher than clamping end 11 slightly, clamping end 11 can have the trend of pasting tightly to the motion of anti-wind circle 10 under the action of gravity, thereby lock anti-wind circle 10, and then can fasten anti-wind circle 10 in the anti-wind circle fixed slot safely and stably, improve the factor of safety of handling. After the wind-resistant ring 10 is lifted to a specified position, the crane or the crane lowers the lifting end 12, and then the clamping end 11 naturally moves along the width direction of the wind-resistant ring 10 under the elastic action of the wind-resistant ring 10, so that the clamping end 11 and the wind-resistant ring 10 are conveniently disengaged. Wherein, in the lifting process, the width direction of the wind-resistant ring 10 is approximately horizontal.

The specific angle of the oblong hole 31 is such that the rotating shaft 2 is arranged in the oblong hole and can move in the oblong hole along the width direction of the wind-resistant ring 10 relative to the fixing member 3.
