Title (EN) TENSION PULLEY DEVICE FOR ELEVATOR GOVERNOR ROPE
(FR) DISPOSITIF À POULIE DE TENSION POUR CÂBLE DE COMMANDE D’ASCENSEUR
(JA) エレベータ用調速機ロープの張り車装置
Abstract:
(EN) A tension pulley device for an elevator governor rope has a tension pulley suspended by the governor rope, a pivoting member rotated by a vertical displacement of the tension pulley, a restraining member whose distance from the pivoting member is reduced when the pivoting member is pivoted into the direction in which the tension pulley is displaced upward, a wedge inserted between the pivoting member and the restraining member, and an urging member for urging the wedge into the direction in which the wedge pushes and spreads the distance between the pivoting member and the restraining member. A supporting member is provided in a hoistway, and the pivoting member and the restraining member are disposed on the supporting member. The wedge has a first contact surface coming into contact with the pivoting member and a second contact surface inclined relative to the first contact surface and coming into contact with the restraining member. Pushing of the wedge into the gap between the pivoting member and the restraining member prevents the tension pulley from being displaced upward.
(FR) L’invention concerne un dispositif de poulie de tension pour câble de commande d’ascenseur. Ce dispositif comprend une poulie de tension suspendue par le câble de commande, un élément d’articulation actionné en rotation par un déplacement vertical de la poulie de tension, un élément de retenue dont la distance par rapport à l’élément d’articulation est réduite lorsque l’élément d’articulation tourne dans la direction dans laquelle la poulie de tension se déplace vers le haut, une cale insérée entre l’élément d’articulation et l’élément de retenue, et un élément de poussée permettant de pousser la cale dans la direction dans laquelle la cale pousse et augmente la distance entre l’élément d’articulation et l’élément de retenue. Un élément support est installé dans la cage d’ascenseur, et l’élément d’articulation et l’élément de retenue sont disposés sur l’élément support. La cale possède une première surface de contact venant au contact de l’élément d’articulation et une seconde surface de contact inclinée par rapport à la première surface de contact et venant au contact de l’élément de retenue. Le fait de pousser la cale dans l’espace entre l’élément d’articulation et l’élément de retenue empêche la poulie de tension de se déplacer vers le haut.
(JA)  エレベータ用調速機ロープの張り車装置は、調速機ロープに吊り下げられた張り車と、張り車の上下方向への変位により回動される回動部材と、張り車が上方へ変位される方向へ回動部材が回動されることにより回動部材との間の間隔が小さくなる規制部材と、回動部材と規制部材との間に挿入される楔と、楔が回動部材と規制部材との間の間隔を押し広げる方向へ楔を付勢する付勢部材とを有している。昇降路内には、支持部材が設けられている。回動部材及び規制部材は、支持部材に設けられている。楔には、回動部材に当接する第1の当接面と、第1の当接面に対して傾斜され、規制部材に当接する第2の当接面とが設けられている。回動部材と規制部材との間に楔が押し込まれることにより、張り車の上方への変位が防止される。
