To inspect sheave wear using sensors that can be installed in an elevator with simple operation.SOLUTION: There is provided a system for inspecting wear on sheaves of a rope-type elevator, comprising an angular velocity detection device installed on a sheave of a hoisting machine, an acceleration detection device installed in a car, and a wear inspection device that determines the state of the sheave based on the data of the angular velocity detection device and the acceleration detection device. The wear inspection device calculates the radius or diameter of the sheave using the acceleration of the car and the angular velocity of the sheave, and determines whether the sheave is worn by determining whether the difference between the radius or diameter and its initial or design value is below a sheave wear reference value.SELECTED DRAWING: Figure 4

    【課題】簡単な作業によりエレベータに設置可能なセンサを用いて、シーブの摩耗を検査する。【解決手段】ロープ式のエレベータのシーブに生じる摩耗を検査するシステムにおいて、巻上機のシーブに設置された角速度検出装置と、乗りかごに設置された加速度検出装置と、角速度検出装置及び加速度検出装置のデータに基づいて、シーブの状態の判定をする摩耗検査装置と、を備え、摩耗検査装置は、乗りかごの加速度とシーブの角速度とを用いてシーブの半径又は直径を算出し、半径又は直径とその初期値又は設計値との差がシーブ摩耗基準値を下回るかどうかによりシーブが摩耗しているかを判定する。【選択図】図4
