PROBLEM TO BE SOLVED: To provide an abnormality detecting device and an abnormality detecting method for a safety device of a passenger conveyor, which can inspect and adjust a position of a safety switch without detaching a driving chain from a sprocket and inspect an operation state of a link mechanism.SOLUTION: An abnormality detecting device 16 for a safety device detects an abnormal state of the safety device of a passenger conveyor 100, and the abnormality detecting device 16 for a safety device comprises: an insertion portion 19 which is inserted into insertion holes 34 and 36 as link supporting points of a link mechanism 30 and temporarily fastens the link mechanism 30; a bolt head 18 arranged at one end of the insertion portion 19; and a link stopper portion 17 provided in the bolt head 18. The link stopper portion 17 has a sectorial-column shape, where a center angle of the sectorial column shape is less than 180 degrees, and a corner part 17A contacts a driving chain 4 according to depths at which the insertion portion 19 is inserted into the insertion holes 34 and 36.SELECTED DRAWING: Figure 9

    【課題】駆動チェーンをスプロケットから取り外すことなく安全スイッチの点検及び位置調整を行うことができ且つリンク機構の作動状態を点検することができる安全装置異常検出装置及び異常検出方法を提供する。【解決手段】乗客コンベア100の安全装置の異常状態を検出する安全装置異常検出装置16であり、安全装置異常検出装置16は、リンク機構30のリンク支点である挿入穴34及び36に挿入され、リンク機構30を仮止めする挿入部19と、挿入部19の一端に配設されたボルトヘッド18と、ボルトヘッド18に設けられたリンクストッパ部17を有し、リンクストッパ部17は、扇柱形状を有し、扇状の中心角が180度未満であり、挿入部19の挿入穴34及び36に対する挿入深さに応じて、角部17Aが駆動チェーン4に接触する。【選択図】図9
