Disclosed is a maintenance device for an electric working device for an emergency stop device, which can improve the safety guarantee of an electrical equipment unit. A maintenance device for maintaining the operation of an electric operator (10) for operating a drive mechanism for driving an emergency stop device for an elevator, the maintenance device being provided with: a movable element (34) mechanically connected to the drive mechanism; electromagnets (35a, 35b) that face the movable element; and an electric mechanism part for converting the rotation of the motor (37) into the linear movement of the electromagnet, the inspection device is provided with: a current sensor (45) for detecting the motor current flowing through the motor; and a controller (200) that, when the electric mechanism unit moves between a first position at which the electromagnet attracts the mover while the electric actuator is in a standby state, and a second position at which the mover moves as the drive mechanism is operated by the electric actuator. On the basis of the motor current detected by the current sensor, at least one of an abnormality in the electric mechanism and a sign of occurrence of the abnormality is detected.
公开了能提升电气设备部的安全保障性的紧急停止装置用电动工作器的检修装置。该检修装置对电动工作器(10)的动作进行检修,其中,该电动工作器(10)使驱动电梯用紧急停止装置的驱动机构工作,具备:可动件(34),其与驱动机构机械连接;电磁铁(35a、35b),其与可动件对置;和电动机构部,其将电动机(37)的旋转变换成电磁铁的直线的移动,该检修装置具备:电流传感器(45),其检测流过电动机的电动机电流;和控制器(200),其在通过电动机构部而电磁铁在电动工作器的待机状态下电磁铁吸附可动件的第1位置、与伴随通过电动工作器使驱动机构工作而可动件移动的第2位置之间移动时,基于由电流传感器检测到的电动机电流来检测电动机构部中的异常以及异常发生的预兆的至少一方。
