The invention relates to a protection method of an electromagnetic chuck lifting appliance redundancy protection system in the technical field of electromagnetic chuck lifting appliances, and the electromagnetic chuck lifting appliance redundancy protection system comprises an electromagnetic chuck lifting appliance, a C-shaped lifting hook and driving equipment, the protection method comprises the following steps that S100, a material detection device is used for detecting whether the electromagnetic chuck lifting appliance adsorbs materials or not, if the detection result is yes, the step S200 is executed, and if not, driving equipment is not powered on; s200, a gravity detection device is used for detecting whether the electromagnetic chuck lifting appliance lifts the lifted object or not, if the detection result is yes, the step S300 is executed, and if not, the driving equipment is not powered on; according to the invention, the action of the C-shaped lifting hook can be automatically controlled by a plurality of detection devices, so that the C-shaped lifting hook supports a lifted object in time, the lifted object is prevented from falling, and compared with the prior art that a storage battery for keeping magnetism in power failure is added, the device is safer and more reliable.

    本发明涉及电磁吸盘吊具技术领域的一种电磁吸盘吊具冗余保护系统的保护方法,所述电磁吸盘吊具冗余保护系统包括电磁吸盘吊具、C型吊钩、驱动设备,所述保护方法包括以下步骤:S100:利用物料检测装置检测电磁吸盘吊具是否已经吸附有物料,如检测结果为是,则进入S200,否则驱动设备不通电;S200:利用重力检测装置检测电磁吸盘吊具是否已经起吊被吊物,如检测结果为是,则进入S300,否则驱动设备不通电;本发明能够多个检测设备实现自动控制C型吊钩动作,使得C型吊钩对被吊物进行及时承托,防止被吊物坠落,相比于现有技术通过增加断电保磁的蓄电池,本发明更加的安全可靠。
