[0044] Please refer to Figures 1-5 , the present utility model provides a technical solution: a combined hook for large-scale lifting, including a fixed seat 8. Both lower surfaces of the left and right sides of the fixed seat 8 are fixedly connected with support frames 1. The support frames 1 are in a "triangle" shape. A threaded rod groove 12 is formed on the outer surface of the fixed seat 8. Two universal wheels 2 are arranged below each of the two support frames 1. The tops of the four universal wheels 2 are respectively fixedly connected with the lower surfaces of the corresponding support frames 1. A motor 6 is fixedly connected to the upper surface of the fixed seat 8. A threaded rod 13 is rotatably connected inside the threaded rod groove 12. One end of the threaded rod 13 close to the motor 6 rotatably extends out of the fixed seat 8. The output end of the motor 6 is fixedly connected with one end of the threaded rod 13 through a transmission belt. Two support rods 19 are fixedly connected inside the threaded rod groove 12. A protection device is arranged below the fixed seat 8.
[0045] Among them, the protection device includes a limit slider 14. The limit slider 14 is threadedly connected to the outer wall of the threaded rod 13. Two first hook combiners 7 are fixedly connected to the lower ends of the left and right sides of the limit slider 14. The limit slider 14 is slidably connected to the outer walls of the two support rods 19.
[0046] Among them, two steel wire ropes 5 are installed on the outer walls of the hooks on the two first hook couplers 7. A protective seat 9 is arranged below the fixed seat 8. Two fixing rods 3 are fixedly connected to the inside of the two slots at the upper end of the protective seat 9. The four steel wire ropes 5 are respectively sleeved on the outer walls of the corresponding fixing rods 3.
[0047] Among them, sliding seat grooves 18 are formed on the outer surfaces of the left and right sides of the protective seat 9. Sliding seats 16 are slidably connected to the inside of the two sliding seat grooves 18. Protective plates 11 are fixedly connected to the ends of the two sliding seats 16 away from the sliding seat grooves 18.
[0048] Among them, a second hook coupler 10 is fixedly connected to the lower surface of the protective seat 9. Three limiting rods 17 are fixedly connected to the outer surfaces of the ends of the two sliding seats 16 close to the sliding seat grooves 18. Three limiting rod grooves 4 are formed in the inside of the two sliding seat grooves 18.
[0049] Among them, the ends of the six limiting rods 17 close to the limiting rod grooves 4 are respectively slidably connected to the inside of the corresponding limiting rod grooves 4. Return springs 15 are sleeved on the outer walls of the six limiting rods 17. The two ends of the six return springs 15 are respectively fixedly connected to the inner walls of the corresponding sliding seat grooves 18 and the outer walls of the sliding seats 16.
[0050] Further, when using this device, it is started by connecting to an external power supply. Push the support frame 1 and then move the device to a specified position through the universal wheels 2. Start the motor 6. One end of the threaded rod 13 is fixedly connected to the output end of the motor 6 through a transmission belt. Then the limiting slider 14 is threadedly connected to the outer wall of the threaded rod 13. Furthermore, the output end of the motor 6 rotates to drive the threaded rod 13 to rotate, and then the limiting slider 14 is driven to move left and right by the rotation of the threaded rod 13.
[0051] Further, the other ends of the steel wire ropes 5 sleeved on the first hook coupler 7 are sleeved on the fixing rods 3 on the protective seat 9. Furthermore, the second hook coupler 10 is fixedly connected to the lower surface of the protective seat 9. Furthermore, the position of the second hook coupler 10 is adjusted by the left and right movement of the limiting slider 14. Then the second hook coupler 10 is used to lift an object. Furthermore, when the second hook coupler 10 shakes due to the weight of the object and drives the protective seat 9 to shake left and right and accidentally collides with other objects, the protective plate 11 contacts other objects first. Furthermore, the protective plate 11 moves left and right due to the acting force generated by the collision.
[0052] Further, the sliding seat 16 slidably connected inside the sliding seat groove 18 formed on the protective seat 9 is fixedly connected to the protective plate 11. Then, the limiting rod 17 on the sliding seat 16 is slidably connected inside the limiting rod groove 4 formed on the sliding seat groove 18. Furthermore, both ends of the return spring 15 are fixedly connected to the inner wall of the sliding seat groove 18 and the outer wall of the sliding seat 16 respectively, and then buffering of the sliding seat 16 is achieved. Furthermore, when the protective plate 11 moves left and right, it drives the sliding seat 16 to move left and right and at the same time drives the limiting rod 17 to move left and right. Furthermore, when the return spring 15 contracts, it buffers the sliding seat 16 at the same time, thus greatly reducing the acting force generated during collision.
[0053] When the protective plate 11 in the protection device moves left and right, it drives the sliding seat 16 to move left and right and at the same time drives the limiting rod 17 to move left and right. Furthermore, when the return spring 15 contracts, it buffers the sliding seat 16 at the same time, thus greatly reducing the acting force generated during collision. At the same time, the loss of the equipment during collision is reduced, the service life of the equipment is greatly improved, the equipment is effectively protected, the equipment damage caused by collision of the equipment is avoided, and the work efficiency is effectively improved. The output end of the motor 6 rotates to drive the threaded rod 13 to rotate, and then the threaded rod 13 rotates to drive the limiting slider 14 to move left and right. Then, the other end of the steel wire rope 5 sleeved on the first hook 7 is sleeved on the fixed rod 3 on the protective seat 9. Furthermore, the position of the second hook 10 is adjusted by the left and right movement of the limiting slider 14, thus ensuring the safe distance between the lifted object and the hook and effectively protecting the object to be lifted. At the same time, the practicability and flexibility of the equipment are greatly improved.
[0054] Working principle: Push the support frame 1 and then move the device to the specified position through the universal wheels 2. After that, start the motor 6. One end of the threaded rod 13 is fixedly connected to the output end of the motor 6 through a transmission belt. Then, the limit slider 14 is threadedly connected to the outer wall of the threaded rod 13. Thus, the rotation of the output end of the motor 6 drives the threaded rod 13 to rotate. Then, the rotation of the threaded rod 13 drives the limit slider 14 to move left and right. The other end of the steel wire rope 5 sleeved on the first hook 7 is sleeved on the fixed rod 3 of the protective seat 9. Thus, the second hook 10 is fixedly connected to the lower surface of the protective seat 9. Then, by moving the limit slider 14 left and right, the position of the second hook 10 is adjusted. Then, the second hook 10 is used to hoist the item. When the second hook 10 shakes due to the weight of the item and drives the protective seat 9 to shake left and right and accidentally collides with other items, the protective plate 11 contacts other items first. Thus, the acting force generated by the collision causes the protective plate 11 to move left and right. The sliding seat 16 slidably connected inside the sliding seat groove 18 opened on the protective seat 9 is fixedly connected to the protective plate 11. Then, the limit rod 17 on the sliding seat 16 is slidably connected inside the limit rod groove 4 opened on the sliding seat groove 18. The two ends of the return spring 15 are respectively fixedly connected to the inner wall of the sliding seat groove 18 and the outer wall of the sliding seat 16. Then, buffering for the sliding seat 16 is realized. When the protective plate 11 moves left and right and drives the sliding seat 16 to move left and right, the limit rod 17 is also driven to move left and right. Thus, while the return spring 15 contracts, buffering for the sliding seat 16 is carried out, which greatly reduces the acting force generated during the collision.
[0055] The above has described the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present utility model.
