[0021] The utility model has the following beneficial effects:

[0022] 1. In the present invention, when the bottom of the hoist contacts the top of the building object, the bottom part of the top ring descends along the outside of the guide rod, the clamp contacts the top of the abutment plate, and the top ring drives the bottom part down, and drives the clamp rod to rotate, and turns through the support block, so that the clamp is disengaged from the U-shaped frame. At this time, the clamp rod wraps around the outside of the building object. When the clamp is unlocked from the U-shaped frame, the top ring and the part at the bottom of the top ring are pulled up by the assembly ring, and the bottom ring pulls the clamp rod to rotate and clamp the object. The top ring continues to pull upward, so that the bottom ring increases the clamping force through the clamp rod connected to the positioning block, achieving secondary clamping through gravity, which can provide additional stability during the lifting process. This helps prevent the object from moving or shaking during the lifting process, thereby reducing the risk of damage.

[0023] 2. In the present invention, the weight of the object and the sling is transmitted through the connecting block, causing the damper and tension spring to pull to varying degrees. This pulling force causes the adjustment rod to move up and down within the through-hole of the support frame, while simultaneously causing the left and right sides of the cone-shaped rod to slide within the through-hole slot of the adjustment rod. The elastic potential energy of the tension spring and damper helps maintain the top ring in a balanced state, and the chute is kept horizontal by the lifting ring connected to the assembly ring. This achieves stable adjustment based on the center of gravity on the surface of the movable adjustment module, allowing the lifting frame to automatically correct its center of gravity to the center position based on center of gravity deviations, maintaining the frame's levelness.

[0033] refer to Figure 2 、 Figure 3 The outsides of the three guide rods 2 are slidably connected to the inner wall of the central hole of the bottom ring 7. A wave ring 2 8 is fixedly connected to the center of the bottom ring 7. The bottom ring 7 slidably connects to the outsides of the three guide rods 2 and is fixedly connected to the wave ring 2 8. The bottom ring 7 provides a stable base, allowing the clamping assembly to effectively clamp objects. The inside of the wave ring 2 8 is slidably connected to a support block 9. The wave ring 1 5 and the wave ring 2 8 are fixed to the inside of the top ring 4 and the bottom ring 7, respectively. The sliding connection and support block 9 provide stability and flexibility for the mechanical connection.

[0034] The exterior of support block 9 is slidably connected to the central inner wall of wave ring 1 5. Three guide posts 10 are fixedly connected to the exterior of support block 9. The exterior of guide posts 10 is slidably connected to the bottom end of wave ring 1 5. The exterior of guide posts 10 is slidably connected to the top end of wave ring 2 8. The bottom end of support block 9 is fixedly connected to a clamp 11, which is fixed inside wave ring 2 8. Support block 9 is connected to wave ring 1 5 via guide posts 10 and is fixed to clamp 11. Support block 9 helps stabilize the clamping assembly and allows adjustment of the clamping action. Guide posts 10, which are slidably connected to the exterior of support block 9 and connected to wave ring 1 5 and wave ring 2 8, are used to support and guide the clamping action.

[0035] The outside of the bottom ring 7 is fixedly connected to a plurality of positioning blocks 12. The middle inner wall of the positioning block 12 is rotatably connected to a clamping rod 13. The middle part of the clamping rod 13 is fixedly connected to a positioning block 2 14 on the side close to the back plate 1. The positioning block 12 is fixed to the outside of the bottom ring 7 and connected to the clamping rod 13. The clamping rod 13 expands and contracts according to the center position of the positioning block 2 14 during the clamping process to clamp objects. The clamping rod 13 is connected to the back plate 1 and the positioning block 2 14 and achieves the clamping of objects by rotating and expanding. The side of the positioning block 2 14 away from the clamping rod 13 is fixedly connected to the outside of the back plate 1. The middle part of the bottom end of the back plate 1 is fixedly connected to two U-shaped frames 15. The outside of the bottom end of the clamping member 11 is engaged with the inside of the bottom end of the two U-shaped frames 15. The clamping member 11 is engaged with the U-shaped frames 15 to clamp and release building objects.

[0036] refer to Figure 1、 Figure 4 The top of the top ring 4 is provided with a balancing assembly to increase the stability of the sling. The balancing assembly includes two connecting blocks 16. The top ends of the two connecting blocks 16 are fixedly connected to the front and rear sides of the top of the top ring 4. The middle part of the top end of the connecting block 16 is rotatably connected to a damper 17. The damper 17 is installed in the middle part of the top end of the connecting block 16 and has the function of adjusting and controlling the stability of the sling. The bottom end of the damper 17 is fixedly connected to a limit block 18. The outside of the limit block 18 is rotatably connected to the inner side of the top end of the connecting block 16. The limit block 18 is fixed to the bottom end of the damper 17 to control the range of motion of the damper.

[0037] The outer sleeve of the damper 17 is provided with a tension spring 19, one end of the tension spring 19 is fixedly connected to the left and right sides of the bottom end of the support frame 22, and the other end of the tension spring 19 is fixedly connected to the top of the limit block 18. The tension spring 19 is fixed to the top of the limit block 18 and the bottom end of the support frame 22, providing additional elastic force to balance the movement of the sling. The top of the damper 17 is fixedly connected to the adjusting rod 20. During the lifting or lowering process of the sling, the gravity of the objects and the sling acts on the adjusting rod 20 through the connecting block 16 and the two internally defined dampers 17 and the tension spring 19.

[0038] A through slot 21 is provided in the middle of the adjusting rod 20, and the outside of the two adjusting rods 20 is slidingly connected to the support frame 22. Through holes 23 are provided on the left and right sides of the support frame 22. The outside of the adjusting rod 20 is slidingly connected to the inner wall of the through hole 23, and the adjusting rod 20 is slidingly connected to the through hole 23 of the support frame 22. The balance of the sling is maintained by adjusting the tension of the tension spring 19. A slide groove 24 is provided at the top of the support frame 22, and a cone head rod 25 is slidingly connected inside the slide groove 24. The left and right sides of the cone head rod 25 are slidingly connected to the through slot 21. The middle part of the top of the support frame 22 is fixedly connected to the inner wall of the assembly ring 26, and the cone head rod 25 is slidingly connected in the slide groove 24 opened at the top of the support frame 22. The cone head rod 25 is used to adjust the overall balance and position of the sling.

[0039] Working principle: When in use, first pass the crane hook through the assembly ring 26 and lock it with the assembly ring 26. Then start the crane to drive the sling to rise. At this time, since there is no building object mounted on the bottom end of the sling, the fixed component at the bottom end of the top ring 4 will be in the middle position of the guide rod 2 and the bottom end position of the rubber bump 3 when the top ring 4 is used as the support point.

[0040] When the sling is at the top of the building object, it can be aligned with the top of the building object through the support plate 1. When the support plate 1 contacts the top of the object, the fixed component at the top of the top ring 4 begins to descend along the outside of the guide rod 2 due to gravity. At this time, the clamp 11 will contact the top of the support plate 1, and the component set at the bottom of the top ring 4 will continue to descend. During the continuous descent of the top ring 4, the guide column 10 of the fixed support block 9 at the top of the clamp 11 is engaged with the adjacent side of the wave ring 2 8 and the wave ring 1 5. Therefore, the top ring 4 drives the wave ring 1 5 to indirectly The continuous decline of the wave ring 2 8 will cause the guide column 10 to slide to the position of the inner wall on the adjacent side of the wave ring 2 8 and the wave ring 1 5, and drive the clamp 11 to turn through the connection of the support block 9, and disengage from the U-shaped frame 15. At the same time, since the positioning block 12 of the clamp rod 13 is fixed on the outer edge of the bottom ring 7, when the bottom ring 7 descends, the positioning block 12 will drive the clamp rod 13 to expand toward the outside of the anti-plate 1 with the positioning block 2 14 as the center, so that the bottom end of the clamp rod 13 can better wrap the outside of the building object.

[0041] When the clamp 11 is completely unlocked from the U-shaped frame 15, the top ring 4 and the part connected to the bottom end of the top ring 4 through the bolt rod 6 can be indirectly pulled through the assembly ring 26 to slide with the outside of the guide rod 2, and continue upward along the outside of the guide rod 2. In the upward process of the top ring 4, when the top ring 4 contacts the outside of the rubber bump 3, the bottom ring 7 connected to the top end of the top ring 4 through the bolt rod 6 will pull the clamping rod 13 to rotate around the positioning block 2 14 through the positioning block 1 12. After the clamping rod 13 rotates, it will rotate toward the center position of the back plate 1 to clamp the building object. At this time, the clamping rod 13 will initially clamp the object. For effective fixation, when the top ring 4 is continuously pulled by the component limited by the top of the connecting block 16, the pulling force and the gravity of the object clamped at the bottom are in an opposite force. This force will pull the top ring 4 to continuously pressurize the rubber protrusion 3 upward to compress it, so that the top ring 4 continues to slide to the top of the guide rod 2, and allows the bottom ring 7 to also slide synchronously with the outside of the guide rod 2 upward through the connection of the bolt rod 6. At this time, the clamping rod 13 connected to the outside of the bottom ring 7 through the positioning block 12 will rotate twice with the positioning block 2 14 as the center to increase the clamping force on the object, thereby effectively clamping and transporting the building objects.

[0042] During the process of lifting or lowering the sling, the gravity of the objects and the sling will pass through the connecting block 16, and the dampers 17 and the tension springs 19 defined in the two connecting blocks 16 will be pulled to varying degrees. This pulling force will cause the adjusting rod 20 to slide and move up and down in the through hole 23 of the support frame 22, and allow the left and right sides of the cone head rod 25 to slide in the through groove 21 of the adjusting rod 20. However, due to the elastic potential energy of the tension spring 19 and the damper 17 itself, the top ring 4 will be pulled into a balanced state, and the matching assembly ring 26 will be pulled by the external lifting ring to keep the lifting slide 24 in a horizontal state. Therefore, the device can be operated in an automatically adjusted balanced state, effectively preventing the sling from shaking.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
