自动扶梯的非操纵防逆转保护,是自动扶梯中的重要安全装置,《自动扶梯和自动人行道监督检验规程》(以下简称《检规》)要求“自动扶梯或倾斜式自动人行道应设置一个装置,使其在梯级、踏板或胶带改变规定运行方向时,自动停止运行”。但对其检验方法只是提出“外观检查,手动试验。因制造厂和型号不相同,采用的检验方法也不相同,通常采用测速原理的机型。可采用切除信号来检测。采用其它原理的可采用相应的检测方法。”由于《检规》中对检验方法的描述不是十分的清晰,而且各制造厂对于自动扶梯和自动人行道中非操纵逆转保护动作原理不尽相同,动作 Escalator non-reversing protection against reversal is an important safety device in escalators. The “Escalator and Moving Walkway Supervision and Inspection Procedures” (hereinafter referred to as “inspection regulations”) require that “an escalator or inclined moving walk should be provided with a device , So that the rung, pedal or tape to change the specified operating direction, automatically stop running ”. However, the test method is only proposed “Appearance inspection, manual test. Because the manufacturer and model are not the same, using the test method is not the same, usually using the principle of speed measurement models can be detected by cutting off the signal. Using other principles The corresponding test method can be adopted. ”Since the description of the inspection methods in the“ inspection ”is not very clear, and the operating principles of the non-steering reversal protection in escalators and moving walkways vary from manufacturer to manufacturer, the actions
