Specific embodiments
[0021] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , wherein Figure 1 is a structural schematic diagram of a preferred embodiment of the lifting device for special-shaped building structures provided by the present utility model; Figure 2 is a structural schematic diagram of another perspective of the lifting device for special-shaped building structures provided by the present utility model;

[0024] Figure 4Schematic diagram of the installation structure of the return spring in the hoisting device for special-shaped building structures provided by the present utility model. The hoisting device for special-shaped building structures includes a top plate 1. A support plate 2 is fixedly installed in the middle of the top plate 1. A traction hole 3 is opened on the support plate 2, which facilitates the hoisting device to hoist the lower adjusting mechanism and the workpiece through the traction hole 3. Stable ribs 15 are fixedly installed on both sides of the support plate 2, and the bottom of the stable ribs 15 is fixedly installed on the top plate 1 to fix the whole support plate 2. Stable members are provided at the four corners of the top plate 1. The stable member includes a sleeve 6. A universal ball 5 is fixedly installed at the top of the sleeve 6. Card slots 4 are opened at the four corners of the top plate 1. The universal ball 5 is rotatably arranged inside the card slot 4. The diameter of the universal ball 5 is smaller than the diameter of the card slot 4. The outer side of the universal ball 5 is closely attached to the inner wall of the card slot 4, which facilitates the movement of the universal ball 5 in the card slot 4 and prevents the universal ball 5 from detaching from the inside of the card slot 4. A return spring 21 is fixedly installed inside the sleeve 6. A connecting rod 11 is inserted inside the sleeve 6. The diameter of the connecting rod 11 is smaller than the inner diameter of the sleeve 6. A snap ring 22 is installed at the top of the connecting rod 11. A limit ring is installed at the bottom inside the sleeve 6. The bottom of the snap ring 22 is closely attached to the top of the limit ring to limit the top of the connecting rod 11, so that the top of the connecting rod 11 is always inside the sleeve 6 and prevents the connecting rod 11 from detaching from the inside of the sleeve 6. The top end of the connecting rod 11 is fixedly connected to the bottom of the return spring 21. A universal ball 2 is fixedly installed at the bottom of the connecting rod 11. Card slots 7 are opened at the four corners above the mounting plate 8 to exert a stretching effect on the lower adjusting mechanism. The universal ball 2 is rotatably arranged inside the card slot 7. Specifically, when the air cylinder 16 pushes the counterweight 19 to move, the whole mounting plate 8 will be finely adjusted. After the mounting plate 8 is adjusted, the upper connecting rod 11 will move inside the sleeve 6, so that when the stable member stretches the mounting plate 8, the mounting plate 8 is in a stable state.
[0025] Further, an adjustment mechanism is provided at the bottom of the stabilizing member. The adjustment mechanism includes a mounting plate 8 which is arranged at the bottom of the stabilizing member. A gravity sensor 13 is fixedly installed at the central position below the mounting plate 8. A fixed platform 17 is fixedly installed in the middle above the mounting plate 8. Four cylinders 16 are fixedly installed on the fixed platform 17. The gravity sensor 13 is respectively connected to the four cylinders 16. The four cylinders 16 are evenly arranged on the fixed platform 17. A counterweight 19 is fixedly installed at one end of each cylinder 16. The bottom of the counterweight 19 is in contact with the top of the mounting plate 8. A chute 20 is formed above the mounting plate 8. A guiding block 18 is fixedly installed at the bottom of the counterweight 19. The guiding block 18 is slidably arranged inside the chute 20. The two sides of the guiding block 18 are in contact with the inner wall of the chute 20, which is used to improve the stability of the counterweight 19 during movement, assist the movement of the counterweight 19, and contribute to the reciprocating movement of the counterweight 19. Specifically, when the workpiece is lifted off the ground, due to the offset of the center of gravity of the workpiece, the traction ropes 10 are unevenly stressed. Therefore, the gravity sensor 13 located on the mounting plate 8 can timely sense the change of the center of gravity of the workpiece. After the center of gravity is offset, the cylinder 16 located above and in the opposite direction of the center of gravity offset position works, thereby pushing the counterweight 19 at the top forward to adjust the center of gravity of the workpiece below, so that the center of gravity of the workpiece is consistent with that of the overhead crane above.
[0026] Further, mounting seats 12 are fixedly installed at the four corners below the mounting plate 8. A connecting column 14 is fixedly installed inside each mounting seat 12. A traction rope 10 is sleeved outside the connecting column 14. A hook 9 is fixedly installed at the bottom of the traction rope 10. When hoisting a special-shaped workpiece, the workpiece is suspended around by the hook, and then the hoisting device works to lift it upward. During hoisting, the traction rope 10 located above will lift the workpiece.
[0027] The working principle of the special-shaped building structure hoisting device provided by the present invention is as follows:
[0028] When hoisting a special-shaped workpiece, the workpiece is suspended around by the hook, and then the hoisting device works to lift it upward. During hoisting, the traction rope 10 located above will lift the workpiece.
[0029] When the workpiece is lifted off the ground, due to the offset of the center of gravity of the workpiece, the traction ropes 10 are unevenly stressed. Therefore, the gravity sensor 13 located on the mounting plate 8 can timely sense the change of the center of gravity of the workpiece. After the center of gravity is offset, the cylinder 16 located above and in the opposite direction of the center of gravity offset position works, thereby pushing the counterweight 19 at the top forward to adjust the center of gravity of the workpiece below, so that the center of gravity of the workpiece is consistent with that of the overhead crane above.
[0030] When the cylinder 16 pushes the counterweight 19 to move, the entire mounting plate 8 will be finely adjusted. After the mounting plate 8 is adjusted, the connecting rod 11 located above will move inside the sleeve 6, so that during the stretching of the mounting plate 8 by the stabilizing member, the mounting plate 8 is in a stable state.
[0031] Compared with the related art, the special-shaped building structure hoisting device provided by the present invention has the following beneficial effects:
[0032] The present invention provides a special-shaped building structure hoisting device. When the center of gravity of the workpiece is offset and the traction rope 10 is unevenly stressed, the center of gravity sensor 13 located on the mounting plate 8 can timely sense the change of the center of gravity of the workpiece. After the center of gravity is offset, the cylinder 16 located above and in the opposite direction of the center of gravity offset position works, thereby pushing the counterweight 19 at the top to move forward to adjust the center of gravity of the workpiece below, so that the center of gravity of the workpiece is consistent with the center of gravity of the hoisting device above, so that during the upward movement of the traction rope 10, it can always be in a stable state, greatly improving the stability of the special-shaped workpiece during hoisting and avoiding the situation of collision damage caused by shaking of the special-shaped workpiece during hoisting.
