Rope deterioration detection device, elevator device equipped with rope deterioration detection device, and rope deterioration detection method

摘要

The rope deterioration detection device according to the present invention includes a pair of support portions that support the rope to bend the rope, a bend imparting portion that imparts bending to the rope supported by the pair of support portions, A tension adjusting unit for adjusting the tension of the rope, a reaction force acquiring unit for acquiring a reaction force in a state where the bending is applied by the bending applying unit, and a deflection for acquiring a deflection amount in a state where the bending is applied by the bending applying unit. An acquisition unit, and a deterioration determination unit that calculates a deterioration determination parameter from the relationship between the reaction force acquired by the reaction force acquisition unit and the deflection acquisition unit and the amount of deflection, and determines the deterioration state of the rope.
