The invention discloses a method for judging the power-on state of an electromagnetic lifting beam of a magnetic disk crane, and relates to the technical field of cranes. The degaussing indicating lamp is connected into a traveling crane magnetism adjusting loop, so that the loop of the degaussing indicating lamp is conducted when the electromagnetic lifting beam is powered off; and judging whether the electromagnetic lifting beam of the magnetic disk crane is powered off or not according to whether the degaussing indicating lamp operates or not. The degaussing indicator lamp is installed to help operators such as ground operators to visually and effectively judge the power-on state of the electromagnetic lifting beam, the working efficiency of the ground operators is improved, and the situation that the operators do not communicate with a traveling worker in place or misoperation of the traveling worker occurs when the operators disassemble and assemble the electromagnetic lifting beam is effectively avoided; therefore, safety risks such as equipment damage, even electric shock and the like are caused when the electromagnetic lifting beam works in a power-on state.

    本发明公开了一种磁盘吊行车电磁吊梁通电状态的判断方法,涉及起重机技术领域,包括:在行车上安装消磁指示灯;将所述消磁指示灯接入行车调磁回路中,使所述消磁指示灯的回路在电磁吊梁断电时导通;通过所述消磁指示灯是否运行判断磁盘吊行车的电磁吊梁是否断电。本发明通过安装消磁指示灯,帮助地面指吊工等操作人员直观、有效地判断电磁吊梁通电状态,提高地面作业人员作业效率,有效避免作业人员在拆装电磁吊梁时,与行车工沟通不到位或者行车工误操作,导致在电磁吊梁通电状态下进行作业,造成设备损坏,甚至触电等安全风险。
