[0024] Working principle: By controlling the start of the lifting device 9, the entire device is lowered, the bottom of the installation wheel 514 is in contact with the ground, and the four sets of protective plates 311 are set on the outside of the steel coil 7. The start of the lifting device 9 is controlled to lower the installation box 1, compress the second spring 503, and slide the sliding guide plate 502 in the vertical groove, so that the fourth gear 507 is lowered and meshed with the fourth rack 508 for transmission, driving the rotating cylinder 506 to rotate and reel in the pull rope 509. The pull rope 509 pulls the pull plate 510 downward, compressing the third spring 511, and setting the positioning rod 512 in the installation groove. The start of the control cylinder 406 is controlled to extend the telescopic connecting rod 407 and drive the driving plate 408 to move, so that the second telescopic arm 404 moves with The movable third rack 405 is meshed with the third gear 402 to drive the first telescopic arm 403 to move, and the first telescopic arm 403 and the second telescopic arm 404 are extended and retracted, so that the mounting plate 210 is set on the inner side of the steel coil 7. When the outer side of the connecting box 201 is in contact with the outer side of the steel coil 7, the start of the lifting device 9 is controlled to make the mounting box 1 rise and the movable pull rope 509 loosen, so that the positioning rod 512 is reset in the through hole, and the position of the first telescopic arm 403 and the second telescopic arm 404 is fixed to prevent the first telescopic arm 403 and the second telescopic arm 404 from moving during the lifting process, preventing the steel coil from falling, reducing safety hazards, and improving the use effect of the device. By making the steel coil 7 be sleeved on the outer side of the mounting plate 210, the lifting device 9 is controlled to rise and the movable pull rope 509 is loosened, so that the positioning rod 512 is reset in the through hole, and the position of the first telescopic arm 403 and the second telescopic arm 404 is fixed to prevent the first telescopic arm 403 and the second telescopic arm 404 from moving during the lifting process, preventing the steel coil from falling, reducing safety hazards, and improving the use effect of the device. The device 9 is started and the entire device is pulled upward. Under the influence of the gravity of the steel coil 7, the slider 215 and the moving box 204 descend under the guidance of the fixed rod 202, causing the first spring 203 to expand and contract, so that the first gear 207 engages with the first rack 206 for transmission, driving the first rotating rod 208 to rotate, causing the rotating disk 214 to rotate, and the guide groove of the rotating disk 214 to rotate to push the push rod 213 in the guide groove to move, so that the push rod 213 pushes the support rod 211 to slide in the sliding groove of the connecting plate 209, so that the mounting plate 210 extends outward, so that the outer side of the mounting pad 8 fits with the inner side of the steel coil 7, supporting the inner side of the steel coil 7, facilitating the adaptation of steel coils with different inner diameters, reducing the shaking of the steel coils during the lifting process, and improving work efficiency. It is highly practical. Through the downward movement of the moving box 204, the second gear 302 and the second rack 312 engage in transmission, driving the second rotating rod 301 to rotate. The rotation directions of the second rotating rod 301 and the first rotating rod 208 are opposite, driving the transmission disk 304 to rotate, so that the moving groove of the transmission disk 304 rotates to push the connecting rod 307 in the moving groove to move, so that the connecting rod 307 pushes the telescopic rod 305 to slide in the slot, so that the moving plate 308 is retracted inward, driving the mounting cylinder 309 and the protective plate 311 to retract inward, so that the outer side of the protective plate 311 is fitted with the outer side of the steel coil 7, which fixes the steel coil 7 more stably and makes the steel coil 7 rotate and shake during the hoisting process, reducing wear on the device and extending the service life of the device.
