Embodiment Construction

[0051] figure 1 An embodiment of an elevator installation comprising ropes comprising at least one rope 2 connected to an elevator car is illustrated. Ropes are elongated members with width, thickness and length. Furthermore, the elevator apparatus comprises a sheave arrangement 3a, 3b, 3c, 3d, 3e comprising sheaves 3a1, 3a2; 3b1, 3b2, 3b3; 3c1; 3d1; 3e1, 3e2, the rope 2 is conveyed around a sheave rotating along an axis x extending in the width direction of the rope 2, and the rope position detectors 4, 5 are arranged to detect the position of the rope 2 at the limit position L at a detection point p Displacement in the thickness direction of the rope 2. The limiting position L is (in thickness direction t) on the side of the rope 2 opposite to the sheaves 3a1 , 3a2 ; 3b1 , 3b2 , 3b3 ; 3c1 ; 3d1 ; 3e1 , 3e2 .

[0052] The rope position detectors 4, 5 are arranged to trigger one or more predetermined actions in response to detecting a displacement of the rope 2 in its thick...

Abstract

The invention relates to an elevator arrangement and an elevator. The elevator arrangement comprises at least one rope connected with an elevator car; a rope wheel arrangement comprising at least onerope wheel around which the rope passes turning around an axis, which extends in width direction of the rope; and a rope position detector arranged to detect displacement of the rope over at least onelimit position and to trigger one or more predetermined actions in response to detecting displacement of the rope over a limit position. The rope is arranged to pass around a rope wheel turning around an axis, which extends in width direction of the rope, and the rope position detector is arranged to detect displacement of the rope over a limit position in thickness direction of the rope at a detection point, and to trigger one or more predetermined actions in response to detecting displacement of the rope in its thickness direction over the limit position, said limit position being on the opposite side of the rope than said rope wheel.

Description

technical field [0001] The invention relates to detecting reduced rope tension of an elevator. The elevator is preferably an elevator for vertical transport of passengers and / or goods. Background technique [0002] Elevators typically include an elevator car and a counterweight that are vertically movable in an elevator hoistway. The elevator units may be interconnected by slings suspending the elevator units on opposite sides of one or more sheaves mounted higher than the elevator units. One of the wheels is usually the drive wheel that engages the rope in order to provide the force for moving the rope (and thus also the elevator car and counterweight). The elevator car and counterweight may need to be interconnected by ropes suspended from the elevator car and counterweight. This type of rope is often used to provide compensation for the weight of the hoisting line. In particular, in this way it is possible to eliminate imbalances caused by the suspensions in the case ...
