The invention relates to the technical field of elevators, in particular to an elevator emergency restarting device which comprises a trigger feedback unit, the trigger feedback unit is composed of a synchronous motor, a synchronous rotating wheel and a feedback gear, the synchronous motor is fixedly installed at the top of an elevator shaft through a support, and a rotating shaft is fixedly installed on an output shaft of the synchronous motor; the synchronous rotating wheel is fixedly installed on the rotating shaft. An electric hydraulic machine and a locking motor are designed, when the elevator falls, a person in the elevator can press a button, the electric hydraulic machine pushes the safety tongs to achieve forced braking, meanwhile, an output shaft of the locking motor drives a lead screw to rotate to enable the lead screw to enter a threaded hole in a telescopic rod, and the safety tongs are further locked; the situation that people in the elevator make dangerous behaviors due to excessive panic when an accident occurs is avoided to a certain extent, the hydraulic machine and the locking motor can be restored by pressing the button again, and the maintenance risk of maintenance personnel is reduced.

    本发明涉及电梯技术领域,具体涉及一种电梯应急重启装置,包括触发反馈单元,触发反馈单元由同步电机、同步转轮、反馈齿轮组成,同步电机通过支架固定安装在电梯井的顶部,同步电机的输出轴上固定安装有转轴,同步转轮固定安装在转轴上。本发明设计了电动液压机和锁紧电机,当电梯下坠时,电梯内的人可以按下按钮,电动液压机推动安全钳实现强制制动,同时锁紧电机的输出轴带动丝杆旋转使其进入伸缩杆中的螺纹孔中,进一步锁死安全钳,一定程度上避免了事故发生时电梯内人员过度恐慌做出危险行为的情况,再次按下按钮可以使掉那个液压机和锁紧电机复原,降低了维修人员的维修风险。
