The elevator sill gap protection structure is characterized in that a plate groove is formed in the position, corresponding to a landing door sill of each floor, of an elevator shaft, a tray telescopic device is arranged at the bottom of a lift car, and the tray telescopic device comprises an electromagnetic thruster, an electromagnetic thruster push-out in-place detection switch, an electromagnetic thruster contraction in-place detection switch and a tray; a push rod of the electromagnetic thruster is connected with the tray, the tray corresponds to the tray groove and is pushed out to be inserted into the tray groove to shield the sill gap, and the electromagnetic thruster, the electromagnetic thruster push-out in-place detection switch and the electromagnetic thruster contraction in-place detection switch are in signal connection with an elevator control system. When the elevator runs normally and the lift car is located at the flat layer, the electromagnetic thruster is controlled to push out the tray, the tray is inserted into the tray groove to shield the sill gap, economic losses or injuries caused by accidents can be effectively reduced, when the elevator is ready to start and run, after the elevator is controlled to be closed, the electromagnetic thruster is controlled to contract, and the safety of the elevator is improved. And the tray is contracted to the bottom of the lift car.

    本发明公开一种电梯地坎间隙保护结构,电梯井道对应每个楼层的层门地坎处设置盘槽,轿厢的底部设置托盘伸缩装置,托盘伸缩装置包括电磁推力器、电磁推力器推出到位检测开关、电磁推力器收缩到位检测开关和托盘,电磁推力器的推杆连接托盘,托盘对应盘槽,通过推出插入到盘槽中遮挡住地坎间隙,电磁推力器、电磁推力器推出到位检测开关、电磁推力器收缩到位检测开关分别与电梯控制系统信号连接。本发明在电梯正常运行并在轿厢处于平层时,控制电磁推力器推出托盘,使托盘插入到盘槽中遮挡住地坎间隙,可有效减少意外导致的经济损失或伤害,在电梯准备启动运行时,控制电梯关门后,再控制电磁推力器进行收缩,使得托盘收缩到轿厢的底部。
