扶梯的自动再启动的重复使用的条件是什么?

答案

参考答案:

A.在两端梳齿交叉线,包括它的外边0.3m的附加距离之间,应对梯级、踏板或胶带进行监控,且只有当这个区域内没有人和物时,自动再启动的重复使用才是有效的。为了试验,用一个不透明的直立圆柱,其直径为0.3m、高为0.3m放在这个区域内,均应能被监控装置检测到。如应用传感器作为监控装置,则这些传感器在倾斜直线区段和水平区段每相隔0.3m的距离内置放,而对曲线区段,则在最大间隔为0.2m的距离内置放。

B.根据14.2.1.1,使用者经过时将使自动扶梯或自动人行道启动。当至少是10s时间,监控装置在规定的区段内没有检测到人或物时,启动才是有效的。

C.控制自动再启动的重复使用的应是符合14.1.2的电气安全装置,自控传感元件允许设计在单通道中。
