Each group of lifting mechanisms includes a horizontally arranged load-bearing plate that can adjust its position along the length direction of the lifting plate. The load-bearing plates are all located below the lifting plate and are perpendicular to the lifting plate in the horizontal direction. And at both ends of each load-bearing plate, sling rings that can adjust their positions along the length direction of the load-bearing plate are installed.

Specific embodiments
[0020] To make the objectives, technical solutions and beneficial effects of the present utility model clearer, the following further describes in detail the embodiments of the present utility model with reference to the accompanying drawings.
[0021] As Figures 1 to 6 shown, the present utility model provides a special crane sling for lifting coiled materials, including a horizontally arranged hanging plate 3, a hanging bracket 1 is erected on the top surface of the hanging plate 3, and several groups of hoisting mechanisms 2 arranged side by side along the length direction of the hanging plate 3 are installed on the hanging plate 3. Each group of hoisting mechanisms 2 includes a horizontally arranged load-bearing plate 21 that can adjust its position along the length direction of the hanging plate 3. Specifically, since the load-bearing plate 21 can adjust its position along the length direction of the hanging plate 3, the position of the hoisting mechanism 2 can be adjusted along the length direction of the hanging plate 3; the load-bearing plates 21 are all located below the hanging plate 3 and are perpendicular to the hanging plate 3 in the horizontal direction, and lifting rings 22 that can adjust their positions along the length direction of the load-bearing plate 21 are installed at both ends of each load-bearing plate 21, that is, the distance between the two lifting rings 22 on each load-bearing plate 21 is adjustable; a lifting rope 23 is installed on each lifting ring 22, and a U-shaped locking ring 24 is installed at the end of the lifting rope 23 away from the lifting ring 22. One end of each locking ring 24 is threadedly connected with a locking rod 25 passing through the locking ring 24. One end of the locking rod 25 is located inside the locking ring 24 respectively, and a handle 251 is fixedly sleeved on the other end of the locking rod 25. The handle 251 can facilitate the rotation of the locking rod 25. Specifically, when in use, as Figure 2 shown, the locking ring 24 can be first buckled on the end of the coiled material 4, and then by rotating the locking rod 25, after the locking rod 25 and the locking ring 24 are respectively abutted against the inner wall and the outer wall of the coiled material 4, the coiled material 4 can be clamped and hoisted, so that it can be applicable to the clamping and hoisting of small coiled materials 4 with different outer diameters.
[0022] Specifically, by arranging several groups of hoisting mechanisms 2 on the hanging plate 3, multiple small coils 4 can be hoisted at one time, thereby improving the hoisting efficiency of the coils 4. Secondly, by arranging the locking ring 24 and the locking rod 25, it can be suitable for clamping and hoisting small coils 4 with different outer diameters. Moreover, since the position of the bearing plate 21 on the hanging plate 3 is adjustable, during use, the distance between adjacent two groups of hoisting mechanisms 2 can be adjusted according to the different outer diameters of the coils 4, so as to prevent adjacent two groups of hoisting mechanisms 2 from affecting each other during operation, and thus coils 4 with different outer diameters can be lifted. In addition, coils 4 with different inner diameters can also be hoisted between adjacent two groups of hoisting mechanisms 2. Finally, since the position of the lifting ring 22 on the bearing plate 21 is adjustable, during use, the position of the locking ring 24 can be adjusted accordingly according to the different lengths of the coils 4 to be suitable for hoisting coils 4 with different lengths.
[0023] The specific setting method for the lifting ring 22 to be able to adjust its position along the length direction of the bearing plate 21 is as follows: As Figures 1 to 6 shown, at both ends of the top surface of each bearing plate 21, a plurality of first limiting grooves 211 are vertically opened and equally spaced along the length direction of the bearing plate 21. And between the plurality of first limiting grooves 211 at the same end of the bearing plate 21, a first sliding groove 212 parallel to the length direction of the bearing plate 21 is commonly connected. The first sliding grooves 212 vertically penetrate through the bearing plate 21, and a first moving rod 27 vertically penetrating through the bearing plate 21 is slidably connected in each first sliding groove 212. At the top ends of the first moving rods 27, first limiting plates 28 adapted to the first limiting grooves 211 are coaxially installed. At the bottom ends of the first moving rods 27, the lifting rings 22 are installed. Specifically, during use, when the position of the lifting ring 22 needs to be moved, the first moving rod 27 can be pushed upward by the lifting ring 22 until the first limiting plate 28 is pushed out above the first limiting groove 211, and then the position of the first moving rod 27 can be slid along the first sliding groove 212 to adjust the position of the lifting ring 22. And when the adjustment is in place, the first limiting plate 28 can be placed into the adjacent first limiting groove 211 to fix the position of the lifting ring 22. In this way, during use, the position of the locking ring 24 can be adjusted according to the different lengths of the coils 4 to be suitable for hoisting coils 4 with different lengths.
[0024] Furthermore, as Figures 1 to 5 shown, the first limiting plate 28 and the first moving rod 27 are connected by a plurality of first connecting bolts 281. Specifically, when the first limiting plate 28 is connected to the first moving rod 27, the screw end of the first connecting bolt 281 passes through the first limiting plate 28 and is threadedly connected to the first moving rod 27, and the head of the first connecting bolt 281 abuts against the first limiting plate 28. In this way, it is convenient to disassemble and assemble the first limiting plate 28 on the first moving rod 27, and after removing the first limiting plate 28, it is also convenient to disassemble and assemble the first moving rod 27 on the bearing plate 21.
[0025] The specific setting method for the load-bearing plate 21 to be able to adjust its position along the length direction of the hanging plate 3 is as follows: As Figures 1 to 5 shown, a plurality of second limiting grooves 31 are vertically formed on the top surface of the hanging plate 3 and are equally spaced along the length direction of the hanging plate 3. The number of the second limiting grooves 31 is greater than the number of the load-bearing plates 21, and a second sliding track 32 parallel to the length direction of the hanging plate 3 is commonly connected between several second limiting grooves 31. The second sliding track 32 vertically penetrates the hanging plate 3; a vertically distributed second moving rod 26 is installed on the top surface of each bearing plate 21. The second moving rods 26 all penetrate the hanging plate 3 through the second sliding track 32, and after the top ends of the second moving rods 26 penetrate the hanging plate 3, second limiting plates 29 adapted to the second limiting grooves 31 are coaxially installed. Specifically, during use, when it is necessary to move the position of the load-bearing plate 21, the second moving rod 26 can be pushed upward by the load-bearing plate 21 until the second limiting plate 29 is pushed out above the second limiting groove 31, and then the position of the second moving rod 26 can be slid along the second sliding track 32 to adjust the position of the load-bearing plate 21; when the adjustment is in place, the second limiting plate 29 can be placed into the adjacent second limiting groove 31 to fix the position of the load-bearing plate 21; in this way, during use, the distance between two adjacent hoisting mechanisms 2 can be adjusted according to the different outer diameters of the coiled materials 4, so as to prevent the two adjacent hoisting mechanisms 2 from affecting each other during operation, and thus coiled materials 4 with different outer diameters can be hoisted.
[0026] Furthermore, as Figures 1 to 5 shown, connecting plates 20 are coaxially installed at the bottom ends of the second moving rods 26, and the connecting plates 20 and the load-bearing plates 21 are respectively connected by a plurality of second connecting bolts 201. Specifically, when the connecting plate 20 is connected to the load-bearing plate 21, the screw end of the second connecting bolt 201 passes through the connecting plate 20 and is threadedly connected to the load-bearing plate 21, and the head of the second connecting bolt 201 abuts against the connecting plate 20, so that it is convenient to disassemble and assemble the load-bearing plate 21 on the second moving rod 26.
[0027] Furthermore, as Figure 1 and Figure 2 shown, a hanging ring 241 is fixedly connected to each locking ring 24. Hook 231s are installed at both ends of the lifting rope 23, and the hook 231s at both ends of the lifting rope 23 are respectively hooked to the hanging ring 22 and the hanging ring 241, so that it is convenient to disassemble and assemble the lifting rope 23 on the hanging ring 22, and thus it is convenient to disassemble and assemble the locking ring 24 on the hanging ring 22; in addition, it is also convenient to disassemble and assemble the locking ring 24 on the lifting rope 23.
