To provide a rope shaking detection device for an elevator capable of detecting amplitudes of horizontal shaking in all directions of a rope, enabled without increasing a number of sensors.SOLUTION: A rope shaking detection device comprises: a measurement range sensor 52, arranged at an arrangement position out of a hoistway passage of a car 26 and a balance weight 28, for measuring directions and distances from the arrangement position to objects existing in a horizontal plane including the arrangement position in the hoistway passage, and for outputting the directions and the distances as position information; detection means for detecting position coordinates, in said horizontal plane, of a rope part of either of a main rope part 24A for hanging the car 26 or a balance rope part 32A hanged down from the car 26 from the position information output from said measurement range sensor; and calculation means for calculating amplitude, in said horizontal plane, of horizontal shaking of the rope part being shaken horizontally, according to said position coordinates of said rope part detected by said detection means.SELECTED DRAWING: Figure 2

    【課題】センサの個数を増やすことなく、ロープのあらゆる方向の横振れの大きさを検出することが可能なエレベータ用のロープ振れ検出装置を提供する。【解決手段】かご26および釣合おもり28の昇降経路外に設置され、昇降路内においてその設置位置を含む水平面に存する物体の当該設置位置からの方向と距離を計測し、当該方向と距離を位置情報として出力する測域センサ52と、前記測域センサから出力される位置情報から、かご26を吊るす主ロープ部分24Aおよびかご26から垂下された釣合ロープ部分32Aのいずれかのロープ部分の前記水平面内における位置座標を検出する検出手段と、前記検出手段で検出された前記ロープ部分の前記位置座標から、当該ロープ部分が横振れしたときの当該横振れの前記水平面における振幅を割り出す割出手段と、を含む構成とした。【選択図】図2
