[0026] Example 2
[0027] according to Figure 1 、 2 As shown in Figures 3 and 4, this embodiment proposes a special sling for rolled finished coiled materials, comprising a sling beam 1 and a hook ring 2. A hook ring 2 is provided at the middle position of the top of the sling beam 1, and movable seat plates 3 are provided on both sides below the sling beam 1. The two groups of movable seat plates 3 are driven to move relative to each other by a driving member. The outer sides of the bottoms of the two groups of movable seat plates 3 are provided with hook arms 4, and the lower sides of the inner sides of the two groups of hook arms 4 are provided with supporting arms 5.
[0028] The inner sides of both sets of hook arms 4 are equipped with protective airbags 6, and the sling beam 1 is equipped with an air supply assembly, which is connected to the protective airbags 6. The operator starts the crane and hooks the crane hook onto the hook ring 2 for lifting. The operator starts the drive and operates the movable seat plate 3 to align with the center of the material roll 19 for relative movement, so that the two sets of hook arms 4 approach each other, and cooperate with the support arm 5 to clamp and support the material roll 19 to a balanced position. After uniform force is applied, the air supply assembly is activated to inflate the protective airbags 6 and make uniform force contact with the end face of the coil, preventing the material roll 19 from shaking during lifting and steadily lifting it to the specified position. When it is lifted to the specified site, the protective airbags 6 and hook arms 4 are released, and the material roll 19 is placed on the ground, and the crane lifting is completed.
[0029] The protective airbag 6 is used to clamp the material roll 19 between the two sets of hook arms 4. When in use, the two sets of movable base plates 3 move relative to each other, so that the two sets of hook arms 4 approach each other, and cooperate with the supporting arms 5 to clamp and support the material roll 19. The inner side contacts the material roll 19 through the protective airbag 6. After inflation, it is in uniform force contact with the end face of the coil, preventing the material roll 19 from shaking during lifting, making it more stable and avoiding the problem of the coil being bumped.
[0030] This special hoist for rolled finished coils is equipped with two sets of movable base plates 3 under the hoist crossbeam 1, which move relative to each other. This allows the two sets of hook arms 4 to approach each other and cooperate with the support arms 5 to clamp and support the material coil 19. The inner side contacts the material coil 19 through the protective airbag 6. After inflation, it is evenly forced into contact with the end face of the coil, preventing the material coil 19 from shaking during lifting, making it more stable and avoiding bumps and collisions. During the clamping process, the power motor 15 cooperates with the chain 17 to drive the sprocket 16 to rotate, causing the bidirectional screw 12 to rotate. In conjunction with the action of the nut block 13, the two sets of movable base plates 3 are driven to move relative to each other. The support and guidance function of the walking roller 18 improves the stability of the movable base plates 3 during movement and improves the reliability of the clamping.
