[0003] In the prior art, when lifting aluminum coils, U-shaped slings are usually used for lifting. Chinese patent with publication number CN202089668U discloses a U-shaped hook specifically for aluminum coils, including a U-shaped hook arm, a rib plate is provided on the hook wall, and a lifting hole is provided on the rib plate. When lifting the aluminum coil, the U-shaped hook arm is inserted into the aluminum coil, and then the hook rope of the crane is passed through the lifting hole for lifting; however, the aluminum coil is heavy and is relatively soft due to its own material. The U-shaped hook arm is inserted into the center hole of the aluminum coil. During the lifting process, the aluminum coil needs to be driven to move, which may cause the aluminum coil to shake easily, and may easily cause damage to the aluminum coil at the center hole.

The second sliding rack 843 is meshed with the transmission gear 842.

[0070] In other embodiments, the transmission assembly 840 may be a transmission rod for transmission.

[0071] The implementation principle of the multi-point suspension hoisting device for aluminum coils in this embodiment is as follows: when hoisting the aluminum coil, first, the mobile frame 120 drives the suspension hook 200 to move above the aluminum coil by driving the roller 132, and then the reducer 141 drives the reel 142 to rotate, and the suspension hook 200 drives the balance frame 610 to approach the aluminum coil, and then the motor 660 is adjusted to drive the winding drum 650 to rotate, so that the support arm 400 is away from the end of the connecting arm 570 and approaches the ground, and then the sliding of the mobile frame 120 is controlled to make the support arm 400 move into the center hole of the aluminum coil, and then the suspension arm 300 is slowly lifted so that the second connecting strut 560 on the main support 510 initially abuts against the inner wall of the center hole of the aluminum coil, and then the motor 660 is adjusted to drive the support arm 400 to be parallel to the axis of the center hole of the aluminum coil. The electric push cylinder is then started, which extends and drives the sliding block 533 to slide, and the sliding block 533 drives the second support block 532 to move upward, so that the secondary support 520 is in contact with the aluminum coil, and then the electric push cylinder is started to drive the push block 710 to extrude the aluminum coil, and then the reducer 141 is started, so that the reducer 141 drives the aluminum coil to rise through the balance frame 610, the suspension rope 620, the hanging arm 300, the connecting arm 570 and the support arm 400. During the rising process, the aluminum coil squeezes the main support 510, and the main support 510 drives the second rotating shaft 542 to slide in the extrusion groove 521, so that the end of the secondary support 520 away from the second rotating shaft 542 rotates toward the main support 510, and supports the aluminum coil, thereby improving the stability of the aluminum coil hoisting, and then the aluminum coil is transported to the designated position through the movement of the roller 132.

[0072] When during the lifting process, the end of the aluminum coil away from the connecting arm 570 is heavier or the center of gravity is biased towards the end away from the connecting arm 570, the first connecting strut 550 and the second connecting strut 560 are subjected to force at the end away from the connecting arm 570, so that the third support block 810 rotates slightly, and the third support block 810 drives the first sliding rack 841 to move upward, and the first sliding rack 841 drives the transmission gear 842 to rotate, and the transmission gear 842 drives the second sliding rack 843 to slide, and the second sliding rack 843 drives the adjustment plate 830 to approach the aluminum coil, so that the push block 710 squeezes the aluminum coil again to adjust the center of gravity of the aluminum coil.

[0073] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
