The invention discloses a safe locking device for a sucked material of a lifting electromagnet. The safe locking device consists of a non-magnetic supporting arm, a supporting arm rotating device, a telescopic cross beam and a telescopic vertical rod, wherein the telescopic cross beam is arranged above the sucked material; the upper end of the telescopic vertical rod is fixedly connected with theouter end of the telescopic cross beam; the non-magnetic supporting arm is fixed at the lower end of the telescopic vertical rod; and the supporting arm rotating device drives the non-magnetic supporting arm to rotate around the lower end of the telescopic vertical rod. In the whole lifting working process of the lifting electromagnet, the sucked material is tightly supported by the non-magnetic supporting arm, so that the sucked material can still be prevented from falling off even if power is off and excitation is lost, and the safety of the sucked material is guaranteed.

    本发明公开了一种起重电磁铁被吸物料的安全锁紧装置,由无磁托臂、托臂旋转装置、伸缩式横梁和伸缩式立杆组成,所述伸缩式横梁设置在被吸物料的上方,所述伸缩式立杆的上端与所述伸缩式横梁的外端固定连接,所述无磁托臂固定在所述伸缩式立杆的下端,所述托臂旋转装置驱动所述无磁托臂围绕所述伸缩式立杆的下端旋转。本发明在起重电磁铁的整个吊运工作过程中,通过无磁托臂将被吸物料紧紧托住,即使在断电、失磁时,仍然能保证被吸物料不会掉下来,保证被吸物料的安全。
