Abstract (en)
[origin: EP1900673A1] A tension sheave device for an elevator governor rope includes: a tension sheave which is suspended by a governor rope; a rotating member which is rotated through vertical displacement of the tension sheave; a regulating member which makes the distance between the regulating member and the rotating member smaller through rotation of the rotating member in a direction in which the tension sheave is upwardly displaced; a wedge which is inserted into a gap between the rotating member and the regulating member; and an urging member urging the wedge so that the wedge enlarges by pushing the distance between the rotating member and the regulating member. A support member is provided inside a hoistway. The rotating member and the regulating member are provided on the support member. The wedge is provided with a first contact surface in contact with the rotating member and a second contact surface sloped with respect to the first contact surface and in contact with the regulating member. By forcing the wedge into the gap between the rotating member and the regulating member, upward displacement of the tension sheave is prevented.
