The invention provides a safety protection device and an escalator. The safety protection device comprises a trigger assembly, a detection assembly and an analysis controller. The trigger assembly is installed on the side, close to the apron board, of the step. The detection assembly is located on one side of the step and used for detecting the trigger assembly in the detection area. The analysis controller is in communication connection with the detection assembly. When the step passes through the detection area at a height beyond the preset height relative to the running guide rail, the trigger assembly does not pass through the detection area, the detection assembly does not generate pulses, the analysis controller compares the actual pulses with a theoretical pulse model, and the situation that the size change of the step in the vertical direction exceeds a limit value is detected; and the analysis controller transmits the detected stair abnormal result to an operation controller of the escalator, the operation controller controls the escalator to stop, it is guaranteed that the safety protection device can rapidly detect the stair with the safety risk, protection control is conducted on the escalator, expansion of the fault risk is avoided, and the safety of the escalator is improved.

    本发明提供一种安全保护装置及扶梯。安全保护装置包括触发组件、检测组件及分析控制器。触发组件安装于梯级靠近裙板的一侧。检测组件位于梯级的一侧,并用于对检测区域内的触发组件进行检测。分析控制器与检测组件通信连接。当梯级相对于运行导轨以预设高度之外的高度通过检测区域时,触发组件不通过检测区域,检测组件不产生脉冲,分析控制器将实际脉冲与理论脉冲模型进行比对,检测出梯级沿竖直方向的尺寸变化超出限值,分析控制器将检测到的梯级异常结果传送到扶梯的运行控制器,运行控制器控制扶梯停止,保证安全保护装置能够快速检出存在安全风险的梯级,并对扶梯进行保护控制,避免故障风险扩大,提高扶梯的安全性。
