The invention discloses a lifting electromagnet for lifting bundled section steel, and relates to the field of electromagnets, the lifting electromagnet for lifting bundled section steel comprises: a first power supply module for supplying a three-phase alternating current; the first rectification module is used for converting the three-phase alternating current into direct current and supplying power to the electromagnet in the forward direction through the voltage detection module for excitation; the second rectification module is used for converting the three-phase alternating current into direct current and reversely supplying power to the electromagnet through the voltage detection module for demagnetization; compared with the prior art, the device has the beneficial effects that the device has a power failure or fault magnetic protection effect, and once a power supply is interrupted due to a fault or a system has a fault (power supply phase loss, rectification element damage, no trigger signal and the like), the device can automatically put the standby power supply module and the second power supply module into power supply to ensure that the electromagnet is not powered off and give out a sound-light alarm; and equipment or human injury accidents caused by sudden falling of materials hoisted by the electromagnet are avoided.

    本发明公开了吊运捆扎型钢用起重电磁铁,涉及电磁铁领域,该吊运捆扎型钢用起重电磁铁包括:第一供电模块,用于供给三相交流电;第一整流模块,用于将三相交流电转化为直流电经过电压检测模块为电磁铁正向供电,进行励磁;第二整流模块,用于将三相交流电转化为直流电经过电压检测模块为电磁铁反向供电,进行去磁;与现有技术相比,本发明的有益效果是:本发明具有停电或故障保磁作用,一旦电源因故中断或系统出现故障(电源缺相、整流元件损坏、无触发信号等),本装置能自动将备用电源模块、第二供电模块投入供电,保证电磁铁不断电,并发出声光报警,避免电磁铁吊运的物料突然下落,造成设备或人身事故。
