PROBLEM TO BE SOLVED: To provide a rope groove measurement device capable of easily measuring the amount of a residue of a rope groove of a sheave, around which a rope is wound, even at a narrow place.SOLUTION: A rope groove measurement device 20 includes: a spherical member 11 having the substantially same diameter as a diameter of a rope; a rod-like member 12 penetrating the center of the spherical member 11; a holding member 13 for holding the spherical member 11 at an arbitrary position of the rod-like member 12; and an L-shaped bracket 21 including an action part 22 to which the rod-like member 12 is installed, and an operation part 23 which a worker operates. The worker holds the operation part 23, moves the action part 22 to the vicinity of a sheave having a rope groove to be measured, and measures the amount of a residue of the rope groove by operating the operation part 23 so as to press the spherical member 11 on the rope groove.SELECTED DRAWING: Figure 1
【課題】 ロープが巻き掛けられる綱車のロープ溝の残存量を測定するロープ溝測定装置において、狭い場所においてもロープ溝の測定作業が容易に行えるようにすること。【解決手段】 ロープ溝測定装置20を、ロープ径と略同一の径を有する球状部材11と、球状部材11の中心を貫通する棒状部材12と、棒状部材12の任意の位置で球状部材11を保持する保持部材13と、棒状部材12が取り付けられる作用部22と作業員が操作する操作部23とを有するL型のブラケット21と、を備えた構成にした。そして、作業員が操作部23を持って、作用部22を被測定ロープ溝を有する綱車の近辺へ移動させ、操作部23を操作して球状部材11をロープ溝に押し当ててロープ溝の残存量を測定するようにした。【選択図】 図1
