The first adjusting rod 53 passes through the corresponding first fixing plate 54 and is rotatably connected to the corresponding first fixing plate 54. A driving mechanism 55 for driving the first adjusting rod 53 to rotate synchronously is provided between the ends of the multiple first adjusting rods 53 that are close to each other, and an internal threaded tube 56 slidably connected to the mounting plate 52 is threadedly connected to the ends of the multiple first adjusting rods 53 that are away from each other, and a support plate 57 is fixedly connected to the end of the internal threaded tube 56 that is away from the first adjusting rod 53.

[0020] Specifically, when in use, first, the sling 5 is moved to a suitable position through the trolley walking mechanism 2 and the lifting trolley 3, and the sling 5 is lowered through the lifting mechanism 4 to ensure that the mounting plates 52 are located on both sides of the steel coil. Then, the mounting plates 52 are slid so that the support plates 57 move into the hollow of the steel coil. Then, the first adjusting rod 53 is driven to rotate through the driving mechanism 55, and the first adjusting rod 53 drives the support plates 57 to move toward the inner wall of the steel coil through the internal threaded tube 56, so that the six support plates 57 can be evenly pressed against the inner wall of the steel coil, so that the steel coil can be fixed and the shaking of the steel coil during the lifting process can be reduced, thereby improving the stability and safety of the crane; in addition, through the ingenious design of the first adjusting rod 53, the internal threaded tube 56, the support plate 57 and other components, the rapid fixing and release of the steel coil is achieved, thereby improving work efficiency.

[0021] In some embodiments, the driving mechanism 55 includes a first stepper motor 551 installed on the outside of the mounting plate 52, the output shaft of the first stepper motor 551 is connected to a horizontally arranged transmission rod 552, the transmission rod 552 is connected to the mounting plate 52 in rotation, one end of the transmission rod 552 away from the first stepper motor 551 extends to the inside of the mounting plate 52 and is coaxially fixed with a first bevel gear 553, and a second bevel gear 554 meshing with the first bevel gear 553 is coaxially fixed on the first adjustment rod 53.

The bottom surface of the slide block 512 is fixedly connected to the mounting plate 52. Specifically, when in use, since the threads at both ends of the second adjusting rod 510 have opposite rotation directions, when the second adjusting rod 510 is driven to rotate by the second stepper motor 511, the second adjusting rod 510 can drive the two sliders 512 to drive the mounting plates 52 to move closer to or away from each other, thereby being able to adjust the spacing between the two mounting plates 52 according to the length of the steel coil, and thus being able to adapt to the lifting requirements of steel coils of different sizes, thereby enhancing the versatility and adaptability of the crane.
