[0002] In actual steel plate hoisting operations, heavy industrial settings such as steel mills face significant challenges due to the diverse specifications of steel plates. Different batches and applications of steel plates vary considerably in length and dimensions, while traditional lifting equipment lacks flexible adaptability, necessitating multiple equipment changes for different plate specifications. This process not only interrupts the hoisting operation, consuming significant manpower for disassembling and installing lifting equipment, but also increases operational time costs due to frequent changes, severely hindering the improvement of production efficiency. Meanwhile, adjusting the orientation of steel plates during transport has long been a problem plaguing the industry. In traditional hoisting methods, if the angle of the steel plates needs to be changed to accommodate subsequent processing or stacking requirements, manual assistance or complex external equipment is often required, making the operation cumbersome and posing a high safety risk. Furthermore, most traditional lifting devices lack effective impact-resistant structures. When lifting or lowering steel plates, the weight of the plates can easily damage the devices, shortening their lifespan and potentially causing equipment malfunctions or even safety accidents. Therefore, this invention proposes an electrically rotating, telescopic, impact-resistant electro-permanent magnet lifting device for steel plates to solve the problems existing in the prior art.
