PULLEY MAINTENANCE METHOD AND PULLEY MAINTENANCE DEVICE
To provide a pulley maintenance method and a pulley maintenance device which maintain a concealed pulley and can maintain performance.SOLUTION: A pulley maintenance method for maintaining a pulley in a state in which a wire is hooked, in which a pair of a first tension part and a second tension part for pulling a winding part wound around a groove of the pulley and both ends of the winding part are provided in the wire and a first region wound around the winding part and a second region other than the first region are provided in the pulley, includes the steps of: installing a guide member bent according to a curvature radius of the pulley on the second region; making a rod-shaped body having flexibility pass through the guide member from the side of the first tension part, and making the rod-shaped body bent according to the curvature radius pass around the first region; and collecting the rod-shaped body having passed through the first region from the side of the second tension part, and winding a wire-pass string connected to the rod-shaped body around the first region.SELECTED DRAWING: Figure 2
【課題】隠蔽された滑車を保全すると共に、性能を維持することができる滑車保全方法及び滑車保全装置を提供する。【解決手段】ワイヤが掛けられた状態の滑車を保全する滑車保全方法であって、ワイヤには、滑車の溝に巻回された巻回部と巻回部の両端を引張する一対の第１引張部と第２引張部とが生じており、滑車には、巻回部に巻回された第１領域と、第１領域以外の第２領域が生じており、滑車の曲率に合わせて曲げられたガイド部材を第２領域に設置する工程と、第１引張部の側からガイド部材内に可塑性を有する棒状体を通過させ曲率に曲げられた棒状体を第１領域の周囲において通過させる工程と、第１領域を通過した棒状体を第２引張部の側から回収し、棒状体に接続された通線紐を第１領域に巻回させる工程と、を備える滑車保全方法である。【選択図】図２
