Abstract
Description
まず、おもり側主索端部支持機構を昇降路の天井近傍にまとめて配置した場合は、おもり側主索端部支持機構から昇降路の天井までの空間が狭くなるため、おもり側主索端部支持機構の保守点検作業が困難になる。また、おもり側主索端部支持機構を上下2箇所に分けて配置した場合は、上側のおもり側主索端部支持機構から昇降路の天井までの空間が狭くなるため、おもり側主索端部支持機構の保守点検作業が困難になる。また、下側のおもり側主索端部支持機構は、巻上機を正面から見たときに巻上機の背面側に配置され、この背面側の空間が非常に狭いため、おもり側主索端部支持機構の保守点検作業がますます困難になる。また、おもり側主索端部支持機構を上下2箇所に分けて配置した場合は、保守点検作業を行う作業員が、各々の箇所に応じて作業場所や作業姿勢を大きく変更する必要があるため、作業効率が大きく低下してしまう。
本願は、上記課題を解決する手段を複数含んでいるが、その一つを挙げるならば、昇降路内を移動するつり合いおもりと、昇降路の頂部に設置され、主索が巻き掛けられる駆動プーリを有する巻上機と、巻上機を支持する巻上機支持台と、つり合いおもりから上方に延在する主索の端部が接続されるおもり側主索留め具と、おもり側主索留め具を介して主索の端部を支持するおもり側主索端部支持機構と、巻上機支持台に取り付けられ、おもり側主索端部支持機構を支持する主索端部支持台と、を備えるエレベーターである。おもり側主索端部支持機構は、駆動プーリの中心軸方向から見て巻上機と重ならないように、巻上機の側方に配置されている。
上記した以外の課題、構成および効果は、以下の実施形態の説明によって明らかにされる。
本実施形態においては、おもり側主索端部支持機構52を巻上機22の側方に配置しているため、昇降路12内でつり合いおもり18を上下方向に移動させる場合に、つり合いおもり18とおもり側主索留め具50との干渉を避けることができる。このため、巻上機22の設置位置を高くしなくても、つり合いおもり18の移動範囲を長く確保することができる。また、駆動プーリ38の中心軸方向から見たときに、巻上機22とおもり側主索端部支持機構52の両方を視野に収めることができる。このため、巻上機22およびおもり側主索端部支持機構52の保守点検作業を容易に行うことができる。また、おもり側主索端部支持機構52を巻上機22の側方1箇所にまとめて配置しているため、保守点検作業を行う作業員は、作業場所や作業姿勢を大きく変更しなくても済む。よって、作業効率を高めることができる。また、巻上機22の背面側におもり側主索端部支持機構52が存在しないため、昇降路壁26の壁面26aに近づけて巻上機22を配置することができる。
なお、本発明は、上述した実施形態に限定されるものではなく、様々な変形例を含む。たとえば、上述した実施形態では、本発明の内容を理解しやすいように詳細に説明しているが、本発明は、上述した実施形態で説明したすべての構成を必ずしも備えるものに限定されない。また、ある実施形態の構成の一部を、他の実施形態の構成に置き換えることが可能である。また、ある実施形態の構成に他の実施形態の構成を加えることも可能である。また、各実施形態の構成の一部について、これを削除し、または他の構成を追加し、あるいは他の構成に置換することも可能である。
