To provide a piping attachment/removal work tool of a hydraulic elevator control valve capable of reducing the number of operators required for piping connection/removal work, shortening the work time, and improving the safety.SOLUTION: A piping attachment/removal work tool 10 includes two leg parts 12 linearly arranged in parallel, a fixed plate 20 jointed to the two leg parts so as to be bridged between longitudinal center parts of the leg parts, and a plurality of connection parts 26 for connecting both side parts of the fixed plate at the two leg parts. Bolt through-holes are formed in plural positions in a circumferential direction around a center. The piping attachment/removal work tool can fix a valve to the fixed plate by joining a bolt to a valve through a screw hole formed around a port opening end and the bolt through-holes in the state in which the port opening end of the valve 60 is faced down to be placed on a top side of the fixed plate.SELECTED DRAWING: Figure 8

    【課題】油圧エレベータ制御用バルブの配管脱着作業治具において、配管取り外しまたは結合の作業に必要な人数を少なくでき、かつ、作業時間の短縮を図れるとともに安全性を高くできる構成を提供する。【解決手段】配管脱着作業治具10は、平行な直線状に配置された2つの脚部12と、2つの脚部の長手方向中央部に掛け渡すように連結された固定板20と、2つの脚部において固定板の両側部分を連結する複数の連結部26とを含む。固定板は、中心の周りにおいて周方向複数位置にボルト貫通孔が形成される。配管脱着作業治具は、バルブ60のポート開口端を下にして固定板の上側にバルブを載置した状態で、ポート開口端の周囲に形成されたねじ孔と、ボルト貫通孔とを通じてバルブにボルトを結合することにより、固定板にバルブを固定可能に構成される。【選択図】図8
