自动扶梯楼层板检测装置
摘要：
本实用新型公开了自动扶梯楼层板检测装置，包括：行程开关，所述行程开关固定安装在扶梯桁架上；触发装置，与行程开关配合，所述触发装置可活动地安装在扶梯桁架上；在楼层板正确安装并未移走的情况下楼层板驱动触发装置与行程开关分离，反之，触发装置触发行程开关。采用上述结构的本实用新型中的行程开关处于常闭状态，可以延长其使用寿命。
摘要（英）：

The utility model discloses a detecting device of an escalator floor board. The detecting device comprises a travel switch fixedly mounted on an escalator truss, and a trigger device matched with the travel switch and movably mounted on the escalator truss; in the case that the floor board is mounted accurately and not moved away, the floor board drives the trigger device to be separated from the travel switch, and conversely, the trigger device triggers the travel switch. The travel switch of the detecting device adopting the structure is in a normally closed state so as to prolong the service life.
