There are two driving cylinders 4, which are fixed on the counterweight 3. The two driving cylinders 4 are respectively arranged on both sides of the main beam 1. There are two slide rails 5, which are respectively arranged on both sides of the main beam 1. A eccentric weight 6 is arranged on the output end of each driving cylinder 4. The two eccentric weights 6 are respectively slidably arranged on the slide rail 5. When in use, a lifting belt 7 is sleeved on the lifting ring 2, and the lifting belt 7 is connected to the crane. The deflection mechanism is detachably connected to the lifting belt 7. The two driving cylinders 4 drive the two eccentric weights 6 to slide on the slide rail 5. The position of the center of gravity can be adjusted after the lifting rod 22 lifts up the two steel plate rolls. When the output end of the driving cylinder 4 is extended, the eccentric weight 6 can be pushed to slide in the direction away from the counterweight 3, so that the lifting rod 22 is tilted upward to prevent the steel plate roll from falling.
[0020] like Figure 1~Figure 4 As shown, the deflection mechanism includes a rotating component, which is rotatably set on the counterweight block 3, and a pushing component is set on the rotating component. The pushing component is detachably connected to the lifting belt 7, and the rotating component is used to drive the lifting belt 7 to deflect. Among them, there are two pushing components, and the two pushing components are respectively arranged on both sides of the rotating component. The pushing components are used to push the two sides of the lifting belt 7. The rotating component drives the two pushing components to push the lifting belt 7 so that the whole sling is deflected at a small angle.
[0021] like Figure 1~Figure 4 As shown, the rotating assembly includes a rotating shaft seat 18, a driving cylinder 29, a rotating shaft seat 210, a support rod 11 and a turntable component. The rotating shaft seat 18 is rotatably set on the counterweight block 3, the driving cylinder 29 is rotatably set on the rotating shaft seat 18, the rotating shaft seat 210 is rotatably set on the output end of the driving cylinder 29, the support rod 11 is rotatably set on the rotating shaft seat 210, the turntable component is rotatably set on the counterweight block 3, the turntable component is rotatably connected to the support rod 11, and the turntable component is rotatably connected to the two pushing components.

When the clamping piece 17 is fixed on the lifting belt 7, the rotation angle of the rotating piece 13 may be different due to the different use or fixed position of the lifting belt 7, thereby making the angle of the driving cylinder 2 9 different. The rotating piece 13 can be driven to rotate by extending and shortening the output end of the driving cylinder 2 9. The two push plates 14 on the rotating piece 13 respectively push and pull the two push rods 16 to twist the hook and the lifting belt 7, thereby allowing the sling to deflect at a small angle.
[0023] like Figure 1 to Figure 6 As shown, the spacing adjustment mechanism includes an adjustment shaft 18, a C-hook assembly and a drive cylinder three 19. The adjustment shaft 18 is arranged on the end of the main beam 1 away from the counterweight block 3. The C-hook assembly is rotatably arranged on the adjustment shaft 18. The C-hook assembly is used to lift the steel plate roll. The drive cylinder three 19 passes through the adjustment shaft 18. An adjustment assembly is arranged on the output end of the drive cylinder three 19. The adjustment assembly is detachably connected to the C-hook assembly. The adjustment assembly is used to adjust the distance between the rolled plates lifted by the C-hook assembly. The adjustment assembly is supported at different positions on the C-hook assembly, and then adjusted according to the distance between the hoisted steel coils.
[0024] like Figure 5~Figure 6 As shown, the C-hook assembly includes a lifting frame 1 20 and a lifting frame 21, the lifting frame 1 20 is rotatably arranged on the adjustment shaft 18, and a lifting rod 22 is arranged on the end of the lifting frame 1 20 away from the adjustment shaft 18, and a plurality of adjustment slots 23 are opened on the lifting frame 1 20, and the adjustment slots 23 are detachably connected to the adjustment assembly, and the lifting frame 21 is rotatably arranged on the adjustment shaft 18, and a lifting rod 22 is arranged on the end of the lifting frame 21 away from the adjustment shaft 18, and a plurality of adjustment slots 23 are opened on the lifting frame 21 3. The adjusting groove 23 is detachably connected to the adjusting component. The adjusting groove 23 is arranged on the opposite side of the lifting frame 1 20 and the lifting frame 2 21. The adjusting component is driven by the driving cylinder 3 19 to support the adjusting groove 23, so that the lifting frame 1 20 and the lifting frame 2 21 are opened at different angles. One end of the lifting rod 22 on the lifting frame 1 20 and the lifting frame 2 21 is arranged in an arc shape. When the sling is placed on the ground, the lifting frame 1 20 and the lifting frame 2 21 can be opened under the action of gravity.
[0025] like Figure 5~Figure 6 As shown, the adjustment component includes a support member 24, a baffle 25 and a lifting member. The support member 24 is arranged on the output end of the driving cylinder three 19. Both sides of the support member 24 are rotatably provided with support rods 29. The two support rods 29 respectively support the adjustment slots 23 on the lifting frame one 20 and the lifting frame two 21. The baffles 25 are arranged on both sides of the support member 24. The baffles 25 are in contact with the upper side of the support rod 29. There are two lifting members, which are respectively arranged on both sides of the support member 24. The lifting member includes a slide 1 26 and a slide 2 27. The slide 1 26 is rotatably arranged on the side of the support member 24. The slide 2 27 is rotatably arranged on the support rod 29. The slide 2 27 is slidably connected with the slide 1 26. The slide 1 26 and the slide 2 27 are provided with springs 28. The springs 28 can pull the support rod 29 to rotate upward. The baffle 25 blocks the support rod 29 so that the support rod 29 can only rotate to a horizontal state. When the output end of the drive cylinder three 19 is shortened, it pulls the support member 24 upward. The upper side of the adjustment slot 23 is set as an inclined surface. The support rod 29 contacts the adjustment slot 23 to cause the support rod 29 to rotate. When the support rod 29 contacts the upper adjustment slot 23, the output end of the drive cylinder three 19 extends to push the support rod 29 into the adjustment slot 23, so that the lifting frame one 20 and the lifting frame two 21 are opened to both sides. When the distance between the two lifting rods 22 needs to be shortened, the lifting frame one 20 and the lifting frame two 21 are placed on the ground. Under the action of gravity, the two lifting rods 22 move away from each other, and the support rod 29 is separated from the adjustment slot 23. At this time, the output end of the drive cylinder three 19 is extended to cause the support rod 29 to contact the lower adjustment slot 23, thereby adjusting the position of the support.
[0026] In summary, the working principle of this adjustable double C-hook sling is: The output end of the driving cylinder three 19 shortens and pulls the support member 24 to move upward, and the support rod 29 rotates through the adjusting groove 23. When the support rod 29 contacts the adjusting groove 23 of the upper layer, the output end of the driving cylinder three 19 extends, and the spring 28 pulls the support rod 29 to rotate, so that the support rod 29 contacts the adjusting groove 23 of the upper layer, so that the two lifting rods 22 move away from each other, and the steel plate coil that is far away can be adjusted. The extension and shortening of the output end of the driving cylinder two 9 drives the rotating piece 13 to rotate, and the pushing plate 14 on the rotating piece 13 drives the pushing rod 16 to push the lifting belt 7, so that the lifting ring 2 is deflected, so that the lifting rod 22 is aligned with the center of the steel coil. After the lifting rod 22 lifts the steel coil, the output end of the driving cylinder one 4 drives the eccentric weight block 6 to slide, so that the sling drives the steel plate coil to rotate, thereby preventing the steel plate coil from falling.
[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
