The invention relates to the technical field of elevator maintenance, in particular to an elevator pit safety protection device. A containing groove is formed in the well wall of the bottom pit. The protection device comprises a toe guard, a crawling ladder, a driving assembly, a state sensing assembly, a buzzer and a controller. The toe guard comprises a first fixed part and a first movable part hinged to the interval position of the first fixed part, and therefore the interval area in front of the containing groove can be opened or closed. The ladder stand comprises a fixed part II and a movable part II connected to the fixed part II in a sliding manner, so that a telescopic ladder stand structure is formed, and meanwhile, the whole ladder stand can linearly and horizontally move along the Y axis. The state sensing assembly can sense the states of the toe guard and the crawling ladder, the controller controls the driving assembly to adjust the toe guard and the crawling ladder in sequence according to the states, and finally, after the crawling ladder stretches out to the position above a sill, the buzzer is controlled to make a warning tone. According to the protection device, the safety of related personnel such as operating personnel entering the pit from the landing door entrance of the elevator is effectively improved.

    本发明涉及电梯检修技术领域,特别是涉及一种电梯底坑安全防护装置。底坑的井道壁开设有容纳槽。防护装置包括:护脚板、爬梯、驱动组件、状态感应组件、蜂鸣器和控制器。护脚板包括固定部一以及铰接在固定部一的间隔处的活动部一,以此能敞开或闭合容纳槽前方的间隔区域。爬梯包括固定部二以及滑动连接在固定部二上的活动部二,以此组成可伸缩式的爬梯结构,同时爬梯整体能沿Y轴线性水平移动。状态感应组件能够感应护脚板和爬梯的状态,控制器根据状态来控制驱动组件按照顺序调节护脚板和爬梯,并最终在爬梯伸出至地坎以上后,控制蜂鸣器发出提示音。该防护装置有效提高了作业人员等相关人员由电梯的层门入口进入底坑时的安全性。
