The invention discloses an escalator step missing safety device which comprises a step missing detection assembly and a device state adjusting assembly, and the device state adjusting assembly controls the step missing detection assembly to be located at a working position or a debugging position. The step missing detection assembly comprises a mounting base, an actuating rod assembly, a roller, a pin shaft and a limiting switch; the step missing detection assembly is fixedly installed on the side portion, close to a preset position of an escalator outlet, of the loop driving guide rail through an installation base, the preset position enables the limiting switch to be triggered, and after the escalator is stopped, the missing step portion is not exposed out of the comb plate. Gravity is adopted as a triggering mechanism, the mechanism is reliable, the design is simple, the manufacturing cost is low, energy consumption is small, and practicability is high.

    本发明公开了一种自动扶梯梯级缺失安全装置,包括梯级缺失检测组件和装置状态调整组件,所述装置状态调整组件控制梯级缺失检测组件处于工作位置或调试位置;所述梯级缺失检测组件包括安装基座、动作杆组件、滚轮、销轴和限位开关;所述梯级缺失检测组件通过安装基座固定安装在靠近自动扶梯出口处预设位置的回路驱动导轨侧部,所述预设位置使得限位开关被触发,自动扶梯制停后缺失的梯级部位不露出梳齿板。本发明采用重力为触发机制,机制可靠,设计简单,造价低,能耗小,实用性较大。
