To provide a detection device of a rope tension variation which detects the tension variation of multiple main ropes with a simpler configuration.SOLUTION: A detection device of a rope tension variation according to one embodiment of the present invention comprises a detection plate 35 on which multiple through-holes 36 are formed to pass-through multiple simple rods, and a detector 50 disposed on the opposite side to the installation side of multiple coil springs 23 of the detection plate 35 and disposed away from the detection plate 35 to output a detection signal according to the distance to the detection plate 35. The height position of the detection plate 35 is arranged between the tip of the multiple simple rods 20 and the opposite end to the side in contact with a supporting part 9 of the coil springs 23. The detection plate 35 is operated by pushing the detection plate 35 with the opposite end to the side in contact with the supporting part 9 of the coil springs 23 when the tension of any of the multiple main ropes 4 changes.SELECTED DRAWING: Figure 2

    【課題】 複数の主ロープの張力のばらつきをより簡単な構成により検出する。【解決手段】 本発明の一態様のロープ張力ばらつき検出装置は、複数のシンブルロッドを通す貫通孔36が形成された検出板35と、検出板35の複数のコイルばね23の設置側とは反対側に検出板35と離れて配置され、検出板35との距離に応じた検出信号を出力する検出器50と、を備える。検出板35の高さ位置は、複数のシンブルロッド20の先端部と、コイルばね23の支持部9に接する側とは反対側の端部との間である。また、複数の主ロープ4のいずれかの張力が変化した場合にコイルばね23の支持部9に接する側とは反対側の端部が検出板35を押すことにより、検出板35が動作する。【選択図】図2
