The invention provides a step derailment prevention device of an escalator, and belongs to the technical field of escalators, the step derailment prevention device comprises a step outward turning response part, and when a step is turned outward, the step outward turning response part is in contact with the step and generates displacement; the step eversion response part covers the whole projection surface when the step is everted; when the step extroversion response part displaces, the step extroversion detection part is used for breaking a step derailing prevention switch and sending a step stopping signal to the main control part; the step eversion detection part is arranged outside the action projection plane of the step eversion response part; and the step anti-derailment switch is connected with the step eversion response part. When the stair anti-derailing switch is repaired and maintained, the hitting rod can be horizontally moved out under the condition that the support is not touched, the stair anti-derailing switch support does not need to be disassembled, repair and maintenance are more convenient, when the stair is turned outwards, the hitting point does not directly act on the stair anti-derailing switch, but acts on the stair outward-turning detection part, and protection of the stair anti-derailing switch is facilitated.
本发明提供了一种自动扶梯的梯级防脱轨装置,属于自动扶梯技术领域,包括梯级外翻响应部,在梯级发生外翻时,其与梯级触碰,并发生位移;梯级外翻响应部覆盖梯级外翻时整个投影面;梯级外翻检测部,其在所述梯级外翻响应部发生位移时,打断梯级防脱轨开关,向主控部发送停梯信号;所述梯级外翻检测部设置在所述梯级外翻响应部的动作投影面外;梯级防脱轨开关,其与所述梯级外翻响应部连接。本发明维修保养时,打杆可在不触碰支架的情况下平移出来,无需再去拆卸梯级防脱轨开关支架,维修保养更方便,梯级外翻时,撞击点不直接作用于梯级防脱轨开关,而是作用于梯级外翻检测部,有利于对梯级防脱轨开关的保护。
