| description | PROBLEM TO BE SOLVED: To provide a speed detection device for an elevator, which can correctly detect the speed of a car; and to provide an elevator.SOLUTION: A speed detection device for an elevator, according to one embodiment of the present invention, comprises: a guide rail 12 having rail side faces 10 and 11; a car 14 guided by the rail side faces 10 and 11 of the guide rail 12; first and second rotary encoders 15 and 16 which respectively rotate on the rail side faces 10 and 11 around a horizontal rotary shaft held across the guide rail 12 by the car 14 at even intervals; a controller 17 which selects an output having the larger rotating speed value between the outputs of the rotary encoders 15 and 16, and outputting a stop command when the rotating speed value exceeds a predetermined setting value; and an emergency stop device which urgently stops the car 14 by friction brake force to the guide rail 12 under the stop command from the controller 17.SELECTED DRAWING: Figure 1
【課題】かご揺れ等が生じても、かごの速度を正しく検出することが可能なエレベータ用速度検出装置およびエレベータを提供する。【解決手段】本発明の一実施形態によれば、レール側面１０、１１を有するガイドレール１２と、ガイドレール１２のレール側面１０、１１により案内されるかご１４と、かご１４にガイドレール１２を等間隔で挟んで保持された水平回転軸の周りにそれぞれレール側面１０、１１上を回転する第１および第２のロータリーエンコーダ１５、１６と、ロータリーエンコーダ１５、１６からの出力のうちの何れか大きい回転速度値を持つ出力を選択し、回転速度値が予め決められた設定値を超えると停止指令を出力するコントローラ１７と、コントローラ１７からの停止指令によりガイドレール１２への摩擦制動力によってかご１４を非常停止させる非常止め装置とを備えたエレベータ用速度検出装置が提供される。【選択図】図１ |
