摘　　要：在驱动链断链或主机制动器失效的情况下,如果自动扶梯未配置机械式防逆转保护装置,扶梯会在载荷作用下发生逆转,存在巨大安全风险。文中从造成自动扶梯逆转的原因入手,在分析了自动扶梯机械结构和所受载荷的基础上,运用机械、电气设计、有限元分析和风险评估等方法,设计了一种新型的自动扶梯防逆转制停装置,其结构简单、易于安装,可在扶梯逆转失控情况下直接制停梯级,解决了在用自动扶梯加装防逆转保护装置的难题,同时也可作为自动扶梯制动方式的一种补充。If the drive chain breaks or the main engine brake fails,an escalator can reverse under load in the absence of a mechanical anti-reverse protection device,posing significant safety risks.Addressing the root causes of escalator reversal,a new type of anti-reverse braking device for escalators has been designed.This design is based on a thorough analysis of the escalator’s mechanical structure and load characteristics,and it integrates mechanical and electrical design,finite element analysis,and risk assessment.The device is structurally simple and easy to install.It can directly stop the escalator in the event of reversal,thereby solving the challenge of retrofitting anti-reverse protection devices onto existing escalators.Additionally,it serves as a valuable supplement to the existing braking of escalators.
