To provide a detection device of a step tread lifting capable of detecting the tread lifting of each one step of an escalator.SOLUTION: A detection device 12 of a step tread lifting brings a detection rod 12a into sequentially contact with treads 5b of multiple steps 5 of an escalator 1 and measures the displacement magnitude of the treads. A camera 12h is installed in the position that includes the detection rod 12a and the treads 5b before/after the detection rod 12a in the imaging range at the same time, and images them. A data processing device 16 identifies a demarcation 5c by the brightness change of the image, separates the steps 5 one by one, and detects the lifting magnitude of each one step of the tread.SELECTED DRAWING: Figure 5
【課題】エスカレーターのステップ1枚ごとの踏板の浮き上がりを検知すること。【解決手段】ステップ踏板浮き上がり検知装置12の検知棒12aをエスカレーター1の複数のステップ5の踏板5bに順次接触させて変位量を計測するとともに、検知棒12aと検知棒12aの前後の踏板5bとを同時に撮像範囲に含む位置に設けられたカメラ12hによる撮像を行う。そして、データ処理装置16が画像の明るさの変化からデマケーション5cを識別してステップ5を1枚ごとに区切り、ステップ1枚ごとの踏板の浮き上がり量を検出する。【選択図】図5
