The invention discloses an escalator with a main driving chain bi-direction deviation monitoring device. Detection switches are arranged on two sides of the middle position of a main driving chain correspondingly. Each detection switch is provided with a trigger rod. The distance between each trigger rod and the main driving chain is a set value. The detection switches are triggered when deviationof a chain running track exceeds the set value. The detection switches are connected with a controller of the whole escalator and sends out an escalator stopping signal. The escalator has the advantage that the safety of the escalator is improved.

    本发明公开一种带主驱动链双向偏移监测装置的自动扶梯,主驱动链中间位置的两侧各设有检测开关,所述检测开关带有触发杆,触发杆与主驱动链条之间的距离为一设定值,链条运行轨迹偏离超过设定值,触发检测开关,检测开关与扶梯整机的控制器连接,发出停梯信号。本发明的优点是提高了自动扶梯的安全性。
