Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1: Please refer to Figures 1-4 , a hot-dip galvanizing sling for angle steel of a high-voltage transmission tower, including a top frame 1 and a hoisting motor 2. The hoisting motor 2 is installed at the middle position of the bottom end of the top frame 1. A set of cable winding seats 4 are fixed on both sides of the bottom end of the top frame 1. The output end of the hoisting motor 2 is fixedly connected to a hoisting shaft 3. A cable winding shaft 5 is movably assembled at the cable winding seat 4. A steel cable 6 is wound between the hoisting shaft 3 and the cable winding shaft 5. The bottom end of the steel cable 6 is suspended with a hook sleeve 8. The bottom end of the hook sleeve 8 is suspended with a lock 9. The bottom end of the lock 9 is fixedly connected to a suspension rod 10. A clamping mechanism is arranged at the suspension rod 10; the clamping mechanism includes a servo motor 13 fixed to the top end of the suspension rod 10. The output shaft of the servo motor 13 is fixedly connected to a drive shaft 14. The bottom end of the drive shaft 14 is fixedly connected to a turntable 15. A set of swing arms 16 are hinged at both ends of the turntable 15. The other sides of the swing arms 16 are respectively hinged with moving seats 17. The bottom end of the moving seat 17 is welded with a gripper 18. The top ends of the moving seats 17 are respectively welded with connecting frames 12. A set of rollers 11 are installed at the top ends of the connecting frames 12. The top ends of the rollers 11 walk on the top of the suspension rod 10;

[0025] Specifically, as in Figure 1 andFigure 2 As shown, the sling uses a steel cable 6 as the lifting component, and the angle steel workpiece on the ground is clamped by the clamping mechanism. The servo motor 13 drives the drive shaft 14 to rotate, so that the two groups of turntables 15 move relatively through the rotation of the turntable 15. The four groups of grippers 18 clamp the workpiece. When the moving seat 17 moves, the rollers 11 walk on the top of the boom 10 to ensure the smoothness and stability of the movement of the grippers 18. As the steel cable 6 is wound up, the entire boom 10 rises.

[0026] Embodiment 2: A locking motor 7 is fixedly installed on the outer wall of each of the hook sleeves 8. A toothed rod 22 is movably connected inside the hook sleeve 8. A driving gear 23 and a driven gear 21 are meshed on one side of the toothed rod 22. The locking motor 7 is connected to the driving gear 23 through a transmission belt. A fastening rod 20 is fixedly installed on the other side of the outer wall of the hook sleeve 8. A locking hook 19 is arranged at the bottom end of the driven gear 21. The locking hook 19 and the fastening rod 20 are fastened and connected. A through groove for the rotation of the locking hook 19 is opened at the bottom end of the hook sleeve 8;

[0027] Specifically, as Figure 1 and Figure 4 shown, a locking motor 7 is installed at each of the two hook sleeves 8. If it is necessary to release the connection between the boom 10 and the hook sleeve 8, start the locking motor 7. Through the rotation of the driving gear 23, the toothed rod 22 is pushed to move, thereby driving the rotation of the driven gear 21, that is, the locking hook 19, so that the engagement between the locking hook 19 and the fastening rod 20 is opened, and the locking buckle 9 can be manually removed from the locking hook 19.

[0028] Embodiment 3: The length of the boom 10 is less than that of the top frame 1. The servo motor 13 is located at the middle position of the boom 10. Four groups of grippers 18 are arranged at the four corners below the swing arms 16. The turntable 15 is diamond-shaped. Two groups of swing arms 16 are arranged and kept parallel. Two groups of cable winding shafts 5 are arranged. The winding directions of the steel cable 6 at the two groups of cable winding shafts 5 are opposite;

[0029] Specifically, as Figure 1 and Figure 3 shown, the cable winding shafts 5 are arranged on both sides of the hoisting motor 2. When the hoisting motor 2 drives the hoisting shaft 3 to rotate clockwise, the steel cable 6 is simultaneously unreeled at the two groups of cable winding shafts 5 to lower the boom 10. Similarly, when the hoisting shaft 3 rotates counterclockwise, the steel cable 6 is simultaneously wound up at the two groups of cable winding shafts 5 to hoist the boom 10.

[0030] Working principle: The angle steel workpiece on the ground is clamped by the clamping mechanism. The servo motor 13 drives the driving shaft 14 to rotate, so that the two groups of turntables 15 move relatively through the rotation of the turntable 15. The four groups of grippers 18 clamp the workpiece. When the moving seat 17 moves, the rollers 11 walk on the top of the hanging rod 10 to ensure the smoothness and stability of the movement of the grippers 18. As the steel cable 6 is wound up, the entire hanging rod 10 rises. There are cable winding shafts 5 arranged on both sides of the hoisting motor 2. When the hoisting motor 2 drives the hoisting shaft 3 to rotate clockwise, the steel cable 6 is simultaneously unwound at the two groups of cable winding shafts 5 to lower the hanging rod 10. Similarly, when the hoisting shaft 3 rotates counterclockwise, the steel cable 6 is simultaneously wound up at the two groups of cable winding shafts 5. A locking motor 7 is installed at each of the two groups of hook sleeves 8. If it is necessary to disconnect the connection between the hanging rod 10 and the hook sleeve 8, the locking motor 7 is started. Through the rotation of the driving gear 23, the rack 22 is pushed to move, thereby driving the rotation of the driven gear 21, that is, the locking hook 19, so that the engagement between the locking hook 19 and the locking rod 20 is opened, and the locking buckle 9 can be manually removed from the locking hook 19.

[0031] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
