Abstract
Description
図1は、本発明の実施の形態1によるエレベーター装置の一例を示したものである。図1に示されたエレベーター装置は、1:1ローピング構成である。昇降路1の上部には、機械室2が設けられている。昇降路1の内部には、かご3および釣合おもり4が懸吊体5によってつり下げられており、かご3はガイドレール6に沿って昇降路1の内部を昇降する。懸吊体5としては、例えば、ロープやベルトなどが用いられる。
最下階に位置するときに最も弱くなる。
図9は、本発明の実施の形態2における非常止め装置13の構成図を示したものである。図9に示された構成では、かご3が最下階方向に下降する場合、ローラー18が時計方向に回転し、それによってギア部19が反時計方向に回転し、ラックギア26が上方向に移動する。ラックギア26は楔状体15の制動子21を下方より支える構成となっており、ラックギア26が上方向に移動すると、楔状体15において制動子21が上方向に移動する。例えば、かご3が最下層まで移動した場合、制動子21の非常止め作動前の位置が図3におけるd’の位置まで上方に移動する。これにより、非常止め装置13に制動力が発生する引き上げ距離がdからd’に短くなり、懸吊体5の破断から非常止め装置13が動作するまでの時間が短くなる。一方、かご3が最上階近傍に上昇する場合、制動子21が下方向に移動し、非常止め装置13に制動力が発生する引き上げ距離がd’よりも大きくなり、巻上機8によるブレーキ動作やかご3の内部の乗客によるかご揺すりなどによる非常止め装置13の誤動作を少なくすることができる。
図10は、本発明の実施の形態3における非常止め装置13の構成図を示したものである。図10に示された構成では、かご3が最下階方向に下降する場合、ローラー18が時計方向に回転し、それによってギア部19が反時計方向に回転し、ラックギア27が上方向に移動する。ラックギア27はアーム16の支点23およびばね17の端とつながっており、ラックギア27が上方向に移動すると、アーム16およびばね17が上方向に移動することにより、楔状体15において制動子21が上方向に移動する。例えば、かご3が最下層まで移動した場合、制動子21が図3におけるd’の位置まで上方に移動する。これにより、非常止め装置13に制動力が発生する引き上げ距離がdからd’に短くなり、懸吊体5の破断から非常止め装置13が動作するまでの時間が短くなる。一方、かご3が最上階近傍に上昇する場合、制動子21が下方向に移動し、非常止め装置13に制動力が発生する引き上げ距離がd’よりも大きくなり、巻上機8によるブレーキ動作やかご3の内部の乗客によるかご揺すりなどによる非常止め装置13の誤動作を少なくすることができる。

図15は、本発明の実施の形態5におけるエレベーター装置の構成図を示したものである。実施の形態5におけるエレベーター装置では、昇降路壁30の最下階近傍から最下階にかけて突起部31が設けられている。かご3が最下階近傍に下降すると、リンク32が突起部31に当たることにより、リンク32が矢印の方向に回転し、結果としてばね17が広げられ、ばね17のばね力が低下する。
図16は、本発明の実施の形態6におけるエレベーター装置の構成図を示したものである。実施の形態6におけるエレベーター装置では、昇降路壁30の最下階近傍に突起部33が設けられている。かご3が突起部位置まで下降すると、リンク34が突起部33に当たることにより、リンク34が矢印の方向に回転し、結果としてばね17が広げられ、ばね17のばね力が低下する。リンク34が引き上げられた状態がラッチ35によって保持されたまま、最下階に到達する。かご3が最下階から突起部位置まで上昇すると、引き上げられた状態のリンク34が突起部33に当たることにより、リンク34が矢印と反対の方向に回転し、ばね17が押し込められ、ばね17のばね力が上昇する。リンク34が引き下げられた状態は、ラッチ35によって保持される。
図17は、本発明の実施の形態7におけるエレベーター装置の構成図を示したものである。コントローラ36は、調速機14に設置されているエンコーダの情報からかご3の位置を検出し、かご3の位置情報に基づいてアクチュエータ37を操作する。具体的には、かご3が最下階近傍にあるときはばね17のばね力を弱める方向に、かご3が最下階近傍にないときにはばね17のばね力を強める方向に、アクチュエータ37を操作する。
