To solve the problem in which, with respect to an elevator rope elongation detecting device, the prior art requires an elevator control signal, and a large-scale remodeling is required in advance in order to apply to an elevator that does not have a structure for taking in the control signal.SOLUTION: There is provided an elevator rope elongation detecting system wound around a hoisting machine for detecting the elongation amount of an elevator rope with one end connected to a car and the other end connected to a counterweight, comprising a measuring device attached to the car to measure acceleration and magnetic flux density, and a determination device for detecting an abnormality in the amount of elongation of the rope based on a change in the moving distance from a predetermined reference position when the car moves up and down to a cross position of the car with the counterweight.SELECTED DRAWING: Figure 6

    【課題】 エレベータのロープ伸び量検出装置に関し、従来技術ではエレベータの制御信号を必要としており、予め制御信号を取り込むための構造を持たないエレベータに適用するためには大掛かりな改造を必要としていた。【解決手段】 巻き上げ機に巻きかけられ、一端にかごを接続し、他端に釣合い錘を接続したロープの伸び量を検出するエレベータのロープ伸び量検出システムであって、前記かごに取り付けられ、加速度と磁束密度を計測する計測装置と、前記かごが昇降する際の所定の基準位置から前記釣合い錘とのすれ違い位置までの移動距離の変化に基づいて前記ロープの伸び量の異常を検出する判定装置と、を有することを特徴とするエレベータのロープ伸び量検出システム。【選択図】図6
