[0002] The sling for a bellows is a special lifting tool designed for safely and efficiently hoisting and transporting bellows. It usually has characteristics such as high strength, corrosion resistance, and wear resistance to adapt to harsh industrial environments. In the steelmaking industry, the sling for a bellows is usually used to hoist the bellows to the top of the blast furnace for feeding operations; some of the existing slings for bellows use a method of fixing the positions of each hook to carry out the hoisting work of the bellows, and some of the slings for bellows use a method of non-tension self-adaptation to carry out the hoisting work of the bellows. Such slings for bellows have some problems. For example, the method of fixing the positions of each hook affects the tightness of the cooperation between the sling for the bellows and bellows of different diameter sizes, thereby affecting the stability of the sling for the bellows to lift the bellows. The method of non-tension self-adaptation affects the stability of the cable to pull the bellows through the hook, and at the same time causes damage to the tightness of the cooperation between the cable and the auxiliary wheel.

Specific embodiments
[0021] 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.
[0022] Please refer to Figures 1-3 , this embodiment provides a technical solution: a lifting tool for a bell, including a hoisting frame 1, a hook adjusting mechanism 2 and a tension self-adaptive mechanism 3;
[0023] Hoisting frame 1: At its lower end, uniformly distributed cables 5 are provided. The lower ends of the cables 5 are fixedly connected with first hooks 6. At the lower end of the hoisting frame 1, uniformly distributed fixed columns 4 are fixedly connected. The middle parts of the fixed columns 4 are fixedly connected with the upper ends of the vertically adjacent cables 5. At the lower end of the fixed seat 28, a fixed cable 7 is fixedly connected. The lower end of the fixed cable 7 is fixedly connected with a second hook 8. At the upper end of the hoisting frame 1, a support 9 is fixedly connected. At the upper end of the support 9, a pillar 10 is fixedly connected. At the upper end of the pillar 10, a connecting ring 11 is fixedly connected;
[0024] Hook adjusting mechanism 2: It includes a screw rod 21, a moving seat 23, a connecting seat 24, a support frame 25, auxiliary wheels 26, connecting rods 27, and a fixed seat 28. The screw rod 21 is fixedly connected to the lower end of the lifting frame 1. The upper end of the outer surface of the screw rod 21 is provided with a moving seat 23. The lower end of the screw rod 21 is fixedly connected with a fixed seat 28. Connecting rods 27 are rotatably connected inside both the moving seat 23 and the fixed seat 28. Two vertically adjacent connecting rods 27 are rotatably connected to the same connecting seat 24. The ends of the connecting seat 24 away from the screw rod 21 are fixedly connected with support frames 25. Auxiliary wheels 26 are rotatably connected inside the support frames 25. The auxiliary wheels 26 are respectively installed in cooperation with the vertically adjacent ropes 5. The hook adjusting mechanism 2 further includes a threaded drum 22. The threaded drum 22 is threadedly connected to the upper end of the screw rod 21. The upper end of the outer surface of the threaded drum 22 is rotatably connected to the inside of the moving seat 23. According to the diameter size of the bell, rotate the threaded drum 22. The threaded drum 22 rotates and moves vertically under the action of the screw rod 21. The rotation of the threaded drum 22 drives the moving seat 23 to move downward. The downward movement of the moving seat 23 drives the upper ends of the four upper connecting rods 27 to move downward. The lower ends of the four upper connecting rods 27 all generate an outward thrust on the vertically adjacent connecting seat 24, and at the same time cause the four lower connecting rods 27 to rotate away from the screw rod 21. Finally, the connecting seats 24 all move away from the screw rod 21. The outward movement of the connecting seats 24 drives the laterally adjacent auxiliary wheels 26 to move away from the screw rod 21. The outward movement of the auxiliary wheels 26 drives the corresponding hook one 6 to move away from the screw rod 21 through the vertically adjacent ropes 5, so that the hook one 6 and the hook two 8 can effectively meet the lifting requirements of bells with different diameter sizes;
[0025] Tension self - adapting mechanism 3: It is used for the tension self - adapting adjustment of the vertically adjacent ropes 5. The tension self - adapting mechanism 3 includes sliding grooves 31, sliding seats 32, and tension wheels 35. The sliding grooves 31 are respectively arranged inside the lifting frame 1. Sliding seats 32 are slidably connected inside the sliding grooves 31. The lower ends of the sliding seats 32 are rotatably connected with tension wheels 35. The tension wheels 35 are respectively installed in cooperation with the middle parts of the vertically adjacent ropes 5. The tension self - adapting mechanism 3 further includes sliding columns 33. The sliding columns 33 are fixedly connected inside the sliding grooves 31. The middle parts of the sliding columns 33 are rotatably connected to the upper ends of the sliding seats 32. The tension self - adapting mechanism 3 further includes springs 34. The springs 34 are fixedly connected between the sliding grooves 31 and the laterally adjacent sliding seats 32. The springs 34 are movably sleeved on the outer surfaces of the vertically adjacent sliding columns 33. During the working process of the hook one 6, the rope 5 passes through the upper ends of the adjacent tension wheels 35 and the ends of the auxiliary wheels 26 away from the screw rod in sequence. The middle part of the rope 5 generates an outward thrust on the tension wheels 35. The sliding seats 32 move outward inside the corresponding sliding grooves 31. The outward movement of the sliding seats 32 causes the laterally adjacent springs 34 to be elastically compressed. The elastic force of the springs 34 provides the required tension for the rope 5, thereby ensuring the stable lifting of the bell by the hook one 6.
[0026] The working principle of a hoist for a bell used in the present utility model is as follows: During operation, personnel connect the hoist for the bell with an external crane through the connecting ring 11. Then, according to the diameter size of the bell, the threaded rotating cylinder 22 is rotated. The rotation of the threaded rotating cylinder 22 causes it to move vertically under the action of the screw rod 21. The rotation of the threaded rotating cylinder 22 drives the moving seat 23 to move downward. The downward movement of the moving seat 23 drives the upper ends of the four connecting rods 27 at the upper end to move downward. The lower ends of the four connecting rods 27 at the upper end all generate an outward thrust on the vertically adjacent connecting seats 24, and at the same time cause the four connecting rods 27 at the lower end to rotate in a direction away from the screw rod 21. Finally, the connecting seats 24 all move in a direction away from the screw rod 21. The outward movement of the connecting seats 24 all drives the horizontally adjacent auxiliary wheels 26 to move in a direction away from the screw rod 21. The outward movement of the auxiliary wheels 26 all drives the corresponding first hooks 6 to move in a direction away from the screw rod 21 through the vertically adjacent ropes 5, so that the first hooks 6 and the second hooks 8 can effectively meet the lifting requirements of bells with different diameter sizes. When the first hook 6 reaches the required position, the personnel stop rotating the threaded rotating cylinder 22, and then connect the first hook 6 and the second hook 8 to the bell. Then, the hoist for the bell is driven by an external crane to achieve the lifting of the bell. During the operation of the first hook 6, the rope 5 sequentially passes through the upper ends of the adjacent tension wheels 35 and the ends of the auxiliary wheels 26 away from the screw rod. The middle part of the rope 5 generates an outward thrust on the tension wheels 35, and the sliding seat 32 moves outward inside the corresponding chute 31. The outward movement of the sliding seat 32 all causes the horizontally adjacent springs 34 to be elastically compressed. The elastic force of the springs 34 provides the required tension for the rope 5, thereby ensuring the stable lifting of the bell by the first hook 6.
[0027] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
