The invention relates to a lifting electromagnet only sucking a single steel plate. At least one hollow inner magnetic pole is longitudinally arranged in the electromagnet, outer magnetic poles are arranged on the two sides of the electromagnet, and a coil is arranged in the electromagnet and connected with a junction box on the upper portion of the electromagnet. The lifting electromagnet can suck and lift one steel plate very accurately, and even if a series of factors such as the thickness of the steel plate, the flatness of the steel plate, the abrasion degree of the electromagnet, the airgap between the electromagnet and the steel plate and whether water is accumulated or not during storage of the steel plate are changed, lifting and conveying of the single steel plate is not affected; and sucking and lifting of the single steel plate is not needed to be achieved by magnetism adjusting through a matched control device, an electric control device always outputs the maximum exciting voltage to the electromagnet, so that the operation of lifting and conveying the steel plate is safer and more reliable.

    一种只吸单张钢板的起重电磁铁,电磁铁内部纵向设有至少一个中空内磁极,电磁铁两侧设有外磁极,电磁铁内部设有线圈,线圈连接电磁铁上部的接线盒。本发明的起重电磁铁,能够非常准确的吸吊一张钢板,即使钢板的厚度、钢板的平整度、电磁铁的磨损程度、电磁铁与钢板的气隙、钢板存放时是否积水等一系列因素发生变化,也不影响单张钢板的吊运;在吸吊单张钢板时不需要通过配套控制装置的调磁来实现,电控装置始终输出最大励磁电压给电磁铁,使吊运钢板作业更加安全可靠。
