[0002] The production process of color-coated steel sheets includes: unwinding - stitching - entrance looping - cleaning - chemical treatment - initial coating - initial coating baking - initial coating cooling - fine coating - fine coating baking - fine coating cooling - exit looping - inspection - printing - slitting - coiling, etc. Color-coated steel sheets have the characteristics of delicate texture, lasting color, smooth surface, high strength and good weather resistance, and are widely used in construction, home appliances, furniture and other fields.

[0003] Before processing, the color-coated steel plate needs to be hoisted to the uncoiler for uncoiling. The existing hoisting method is: hang a hoisting plate on the hook of the crane, and grooves are set at both ends of the hoisting plate. The hoisting rope passes through the center hole of the steel coil, and the two ends of the hoisting rope are respectively put into the grooves at both ends of the hoisting plate. When the hook lifts the hoisting plate, the steel coil is lifted synchronously. Although the above method can be used for hoisting, the safety of the hoisting process cannot be guaranteed. It is easy for the hoisting rope to fall out of the groove due to the unstable center of gravity of the hoisting, causing a production safety accident.

[0004] Based on the above technical problems, the inventor proposed a color-coated steel coil lifting device, which has stable lifting and the lifting rope will not fall out of the groove during the lifting process, effectively improving the safety of the lifting operation. Utility Model Content
