PROBLEM TO BE SOLVED: To provide a counter clearance measuring device for an elevator which can clean a light transmission surface of a photoelectronic sensor at frequencies necessary and sufficient to maintain function.SOLUTION: The counter clearance measuring device comprises: a photoelectronic sensor 6 that is used for measuring an interval dimension (counter clearance) Y1 between balance weight 1 which moves up and down a hoistway of an elevator installed in a building in a vertical direction along a guide rail 2 and a buffer 4 installed on a pit floor 3 as a bottom part floor of the hoistway below in a vertical direction of the weight 1; a cleaning device 7 installed near the sensor 6; and an elevator control portion 10 that can control elevation operation of an elevator car connected to the weight 1 with a wire rope and calculate an interval dimension Y1 according to detection signals from the sensor 6 which detects well bucket-type operation of the weight 1 accompanying the elevation operation of the elevator car. When abnormality is confirmed from a monitoring result of operation of the sensor 6 by the control portion 10, the cleaning device 7 receives an operation command from the control portion 10 and cleans the light transmission face of the sensor 6.SELECTED DRAWING: Figure 1
【課題】光電センサの光透過面を機能維持に必要十分な頻度で清掃できる清掃装置を備えたエレベータ用カウンタクリアランス測定装置を提供する。【解決手段】この測定装置は、建物に設備されたエレベータの昇降路をガイドレール2に沿って鉛直方向に昇降する釣合い錘1とこの錘1の鉛直方向下方の昇降路の底部床面となるピット床面3に設置された緩衝器4との間隔寸法(カウンタクリアランス)Y1の測定に供される光電センサ6と、センサ6の近傍に設置された清掃装置7と、錘1とワイヤロープにより連結された乗りかごの昇降動作を制御すると共に、乗りかごの昇降動作に伴う錘1の釣瓶式動作を検出したセンサ6からの検出信号に応じて間隔寸法Y1を算出可能なエレベータ制御部10と、を備え、制御部10によるセンサ6の動作監視の結果で異常が確認されたときに清掃装置7が制御部10からの動作指令を受けてセンサ6の光透過面を清掃する。【選択図】図1
