Drawings
FIG. 1 is a schematic structural view of a particular embodiment of a lifting device of the present invention;
in the figure: 1-a suspension arm; 2, hanging; 3-connecting the circular ring; 4-connecting the circular ring upright post; 5-fixing the bottom plate; 6-hanging columns; 7-hand hoist.
Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
The specific embodiment of the hoisting device comprises a manual hoist 7 and a hoisting structure connected with the manual hoist as shown in fig. 1, wherein the hoisting structure comprises more than two hoisting arms 1, the more than two hoisting arms 1 are connected to a middle connecting piece and are uniformly distributed on the same circumference, one ends of the hoisting arms 1 far away from the circle center are provided with hangers 2, and each hoisting arm 1 is movably connected to the middle connecting piece in the circumferential direction. The middle connecting piece comprises a connecting ring 3, and one end of the suspension arm 1 close to the circle center of the connecting ring is provided with a connecting hole which is connected to the connecting ring 3. The hoisting structure and the hoisting object are lifted together in the hoisting process, the hoisting equipment not only overcomes the gravity of the hoisting object, but also overcomes the gravity of the hoisting structure, the middle connecting piece is set into a circular ring, the gravity of the hoisting structure can be reduced, and the force to be overcome by the hoisting equipment is reduced. The suspension arm 1 is rotatably arranged on the connecting ring 3 in a plane passing through the central axis of the connecting ring 3, and the upper side of the connecting ring 3 is provided with a suspension post 6 which is connected with a hand hoist 7 through the suspension post 6.
