【０００１】
【発明の属する技術分野】
この発明は、昇降路の下部に設けられた巻上機にかご及びつり合おもりによる荷重が上向きに作用するエレベーターの昇降路装置に関する。
【０００２】
【従来の技術】
図８〜図１３は、例えば特開平７−１０４３７号公報に示された構成に類似した従来のエレベーターの昇降路装置を示す図で、図８はエレベーターを概念的に示す立面図、図９は図８の昇降路の横断平面拡大図、図１０は図９における昇降路底面の機器配置を示す平面図、図１１は図１０の正面図、図１２は図１１のＡ−Ａ線断面図、図１３は図１０の要部斜視図である。図において、１は昇降路、２は昇降路１内の所定経路を昇降するかご、３は昇降路１に立設されてかご２の両側に配置され、かご２の昇降を案内するかご用案内レールである。
【０００３】
４は昇降路１内の他の所定経路を昇降するつり合おもり、５は昇降路１に立設されてつり合おもり４の両側に配置され、つり合おもり４の昇降を案内するつり合おもり用案内レール、６は昇降路１の下部に配置された巻上機で、駆動綱車７が設けられている。８は昇降路１の頂部に設けられた支持梁、９は昇降路１上部のかご２の側面に対応する位置に固定されたかご側綱止め具である。
【０００４】
１０は主索で、一端がかご側綱止め具９に連結されて下降してかご２の両側に設けられたかご用吊り車１１に巻掛けられて上昇し、支持梁８の下側に枢持されたかご側滑車１２に巻掛けられて下降し駆動綱車７に巻掛けられて上昇し、支持梁８の上側に枢持されたつり合おもり側滑車１３に巻掛けられて下降し、つり合おもり４に設けられたつり合おもり用吊り車１４に巻掛けられて上昇し、他端は支持梁８に連結されている。
【０００５】
１５は昇降路１の底面１６に設けられてつり合おもり４と対向する位置に配置された支持台で、つり合おもり用案内レール５の下端が連結されている。１７は支持台１５の長手の一側が昇降路１の底面１６との間に空所を形成して延長された延長部、１８は支持台１５に立設されてつり合おもり４と対向して配置されたつり合おもり用緩衝器である。

【０００７】
従来のエレベーターの昇降路装置は上記のように構成され、エレベーター装置として巻上機６が付勢されると駆動綱車７が回転して主索１０が駆動される。そして、主索１０の動作によってかご２及びつり合おもり４が互いに反対方向へ昇降する。また、エレベーターの昇降路装置としては、かご２及びつり合おもり４による負荷を支持梁８及びかご側綱止め具９を介して、かご用案内レール３、つり合おもり用案内レール５、支持台１５、昇降路１の構造体によって支持するように構成されている。
【０００８】
【発明が解決しようとする課題】
上記のような従来のエレベーターの昇降路装置において、巻上機６に作用する上向き荷重が支持台１５の延長部１７からなる片持ち梁によって支持される。このため、大きい断面性能を有する延長部１７が必要となり、支持台１５の横断面形高さを高く設計した場合には、つり合おもり４の下降余裕距離を確保するために、つり合おもり４の正常時における下降位置が上昇する。これに対応して、昇降路１の頂部位置を上昇するか又はつり合おもり４の背丈を低くして平面形を増すことになる。したがって、昇降路容積が増大して昇降路１の構築費が嵩むという問題点があった。
【０００９】
この発明は、かかる問題点を解消するためになされたものであり、昇降路容積の増大を伴うことなく巻上機の上向き荷重を支持台によって容易に支持することができるエレベーターの昇降路装置を得ることを目的とする。
【００１０】
【課題を解決するための手段】
この発明に係るエレベーターの昇降路装置においては、エレベーターの昇降路の一側壁中央側と上記一側壁とは反対側の他側壁中央側とに立設され、上記エレベーターのかごの昇降を案内する一対のかご案内レールと、上記一側壁側の上記かご案内レールよりも上記一側壁と交わる上記昇降路の側壁の一方側で、上記かごと上記一側壁との間で上記かごと上記一側壁とに近接して上記昇降路の底面に立設され、上記エレベーターのつり合おもりの昇降を案内する一対のつり合おもり用レールと、上記かごと上記一側壁との間かつ上記一対のつり合おもり用レールの間で上記昇降路の底面に設けられ、上記つり合おもりに対向したつり合おもり用緩衝器と、上記一側壁側の上記かご案内レールよりも上記一側壁と交わる上記昇降路の側壁の他方側かつ上記一側壁側で上記昇降路の底面に近接して水平投影面において上記昇降路中央側が上記かごと重合して配置され、上記かごを昇降させる巻上機と、上記かごと上記一側壁との間かつ上記つり合おもり用緩衝器の上部よりも下方で、長手が水平に配置されると共に幅方向が上記昇降路の底面に対して立設した状態で、上記一対のつり合おもり用レールの下端の上記かご側及び上記一側壁側にそれぞれ連結され、上記巻上機に近い方の上記つり合おもり用レールから上記巻上機側に突出した一対の板体と、上記昇降路の底面よりも上方で上記一対の板体の上記巻上機側端部相互を結合するとともに、上記巻上機の上記一側壁側要部の上側に対向して配置され、上記巻上機に作用する上向き荷重を支持する支持板とが設けられる。
【００１２】
また、この発明に係るエレベーターの昇降路装置においては、上記巻上機に近い方の上記つり合おもり用レールよりも上記支持板側で、上記一対の板体の側面相互を連結した管体が設けられる。
【００１３】
また、この発明に係るエレベーターの昇降路装置においては、エレベーターの昇降路の下部に設置されて水平投影面において上記エレベーターのかごと重合して配置された巻上機、両端に上記エレベーターのかご及びつり合おもりがそれぞれ連結されて上記巻上機によって駆動される主索、上記昇降路に互いに離れて立設されて上記つり合おもりの昇降を案内するつり合おもり用レール、互いに離れて対面し長手が水平に配置されると共に幅方向が上記昇降路の底面に対して立設状態に配置された板体からなり、上記つり合おもり用レールの下端が連結され、かつ上記板体の相互間に上記つり合おもりに対向したつり合おもり用緩衝器が嵌合状態に配置された支持台と、この支持台の長手端部に設けられ一側が上記板体のそれぞれに結合されて、上記昇降路の底面よりも上方に配置され他側は上記巻上機要部の上側に対向して上記巻上機に作用する上向き荷重を支持する支持板とを備え、上記支持台の上記板体を、互いに離れて対面して配置された上記板体の両者の同側の長手端において、上記両者の一方の長手端に対して上記両者の他方の長手端が長手方向に離れて配置されたものとし、上記支持板を、上記両者の同側の長手端に対応する縁部が上記両者の長さの差に応じて傾斜して形成され、上記縁部によって支持される上記巻上機の駆動綱車の回転軸線が上記支持台の長手に対して９０°を超えた交差角を形成して配置される。
【００１４】
【発明の実施の形態】
実施の形態１．
図１〜図５は、この発明の実施の形態の一例を示す図で、図１は昇降路底面の機器配置を示す平面図、図２は図１の正面図、図３は図２のＢ−Ｂ線断面図、図４は図１における支持板箇所の平面図、図５は図１の要部斜視図である。なお、図１〜図５の他は前述の図８〜図１３と同様にエレベーター装置が構成されている。図において、３は昇降路１に立設されてかご２の両側に配置され、かご２の昇降を案内するかご用案内レールである。
【００１５】
６は昇降路１の下部に配置された巻上機で、駆動綱車７が設けられている。１０は駆動綱車７に巻掛けられて前述の図８における主索１０と同様に配置された主索、１９は巻上機６の基部２０の上に配置された防振ゴム、２１は昇降路１の底面１６に設けられてかご２と対向する位置に配置された緩衝器台で、かご用案内レール３の下端が連結され、またかご用緩衝器２２が立設されている。
【００１６】
２３は支持台で、互いに離れて対面し長手が水平に配置されると共に幅方向が昇降路１の底面１６に対して立設状態に配置された板体２４からなり、板体２４の下縁部相互がアンカープレート２５によって連結され、また板体２４の側面相互が管体２６によって連結されている。また、つり合おもり用レール５の下端が板体２４の相互間に装着された取付金具２７を介して連結され、また板体２４の相互間につり合おもり４に対向したつり合おもり用緩衝器１８が嵌合状態に配置されている。
【００１７】
２８はアンカープレート２５に設けられたアンカーボルト、２９は支持板で、支持台２３長手の一側に形成された延長部１７に板面が水平に設けられ、一側が板体２４のそれぞれに設けられた嵌合溝に嵌合されて溶接される。そして、昇降路１の底面１６よりも上方に配置されて、他側は防振ゴム１９を介して巻上機６の基部２０の上側に対向して配置されて巻上機６に作用する上向き荷重を支持する。
【００１８】
上記のように構成されたエレベーターの昇降路装置において、図示が省略してあるがエレベーター装置としては前述の図８〜図１３のエレベーター装置と同様に運転される。そして、エレベーターの昇降路装置としては、かご２及びつり合おもり４による負荷が、支持梁８及びかご側綱止め具９を介して、かご用案内レール３、つり合おもり用案内レール５、支持台２３、昇降路１の構造体によって支持される。
【００１９】
また、主索１０を介して巻上機６に作用する上向き荷重が支持板２９及び板体２４、すなわち支持台２３を介してつり合おもり用案内レール５、昇降路１の構造体によって支持される。そして、支持台２３は互いに離れて対面して配置された板体２４が管体２６及びアンカープレート２５によって相互に連結され、また支持台２３長手の一側に板体２４のそれぞれに固定された支持板２９によって構成されている。
【００２０】
したがって、軽量であって所要の剛性を有する支持台２３を容易に得ることができ、支持台２３の製造費を低減することができる。また、板体２４の相互間につり合おもり用緩衝器１８が嵌合状態に配置されるので、支持台２３の横断面形における高さを高くしても、つり合おもり用緩衝器１８の設置位置が上昇することはない。これによって、昇降路１の頂部位置を上昇したり、つり合おもり５の背丈を低くして平面形を増したりする必要がなく、昇降路容積が増大して昇降路１の構築費が嵩む不具合を解消することができる。
【００２１】
また、管体２６によって板体２４が相互に連結されるので、板体２４のそれぞれに生じる捩じれを防ぐことができ、剛性の高い支持台２３を少ない費用で製作することができる。さらに、板体２４がアンカープレート２５によって相互に連結されて、アンカープレート２５における板体２４相互の間にアンカーボルト２８が配置される。これにより、支持台２３側面からのアンカープレート２５の突出寸法を短くすることができ、少ないスペースに支持台２３を容易に設置することができる。
【００２２】
実施の形態２．
図６及び図７は、この発明の他の実施の形態の一例を示す図で、図６は昇降路底面の機器配置を示す平面図、図７は図６における支持板箇所の平面図である。なお、図６及び図７の他は前述の図１〜図５と同様にエレベーターの昇降路装置が構成されている。図において、図１〜図５と同符号は相当部分を示す。
【００２３】
３０は前述の支持板２９と同様に配置された支持板で、かご用案内レール３側の縁部が延長部１７の先端においてかご用案内レール３から遠退く方向に傾斜して形成されている。そして、巻上機６が支持板３０の傾斜縁部を介して配置されて駆動綱車７の回転軸線がかご側緩衝器台２１の長手に対して傾斜し、図６に示すように反駆動綱車７側がかご用緩衝器２２から遠退く方向に配置される。
【００２４】
上記のように構成されたエレベーターの昇降路装置においても、互いに離れて対面して配置された板体２４、板体２４のそれぞれに固定された支持板３０を主要部材として構成された支持台２３が設けられる。したがって、詳細な説明を省略するが図６及び図７の実施の形態においても図１〜図５の実施の形態と同様な作用が得られる。
【００２５】
また、図６及び図７の実施の形態において、支持台２３に対して支持板３０の傾斜縁部を介して巻上機６が設置される。このため、巻上機６の駆動綱車７の回転軸線が図６に示すように支持台２３の長手に対して９０°を超えた交差角を形成して配置される。したがって、巻上機６の反駆動綱車７の端部と、前述の図９におけるかご２の下降時のかご用吊り車１１との間に空間が形成され、この空間によって昇降路１下部における保守等の作業を容易に行うことができる。
【００２６】
【発明の効果】
この発明は以上説明したように、エレベーターの昇降路の一側壁中央側と上記一側壁とは反対側の他側壁中央側とに立設され、上記エレベーターのかごの昇降を案内する一対のかご案内レールと、上記一側壁側の上記かご案内レールよりも上記一側壁と交わる上記昇降路の側壁の一方側で、上記かごと上記一側壁との間で上記かごと上記一側壁とに近接して上記昇降路の底面に立設され、上記エレベーターのつり合おもりの昇降を案内する一対のつり合おもり用レールと、上記かごと上記一側壁との間かつ上記一対のつり合おもり用レールの間で上記昇降路の底面に設けられ、上記つり合おもりに対向したつり合おもり用緩衝器と、上記一側壁側の上記かご案内レールよりも上記一側壁と交わる上記昇降路の側壁の他方側かつ上記一側壁側で上記昇降路の底面に近接して水平投影面において上記昇降路中央側が上記かごと重合して配置され、上記かごを昇降させる巻上機と、上記かごと上記一側壁との間かつ上記つり合おもり用緩衝器の上部よりも下方で、長手が水平に配置されると共に幅方向が上記昇降路の底面に対して立設した状態で、上記一対のつり合おもり用レールの下端の上記かご側及び上記一側壁側にそれぞれ連結され、上記巻上機に近い方の上記つり合おもり用レールから上記巻上機側に突出した一対の板体と、上記昇降路の底面よりも上方で上記一対の板体の上記巻上機側端部相互を結合するとともに、上記巻上機の上記一側壁側要部の上側に対向して配置され、上記巻上機に作用する上向き荷重を支持する支持板とを設けたものである。
【００２７】
これによって、互いに離れて対面して配置された板体が相互に連結され、また板体それぞれの長手に一側が固定された支持板によって支持台が構成される。このため、軽量であって所要の剛性を容易に得ることができ、支持台の製造費を低減する効果がある。また、板体の相互間につり合おもり用緩衝器が嵌合状態に配置されるので、支持台の横断面形における高さを高くしても、つり合おもり用緩衝器の設置位置が上昇することはない。したがって、昇降路の頂部位置を上昇したり、つり合おもりの背丈を低くして平面形を増したりする必要がなく、昇降路容積が増大して昇降路の構築費が嵩む不具合を解消する効果がある。
【００３０】
また、この発明は以上説明したように、上記巻上機に近い方の上記つり合おもり用レールよりも上記支持板側で、上記一対の板体の側面相互を連結した管体を設けたものである。
【００３１】
これによって、管体によって板体が相互に連結されて、板体のそれぞれに生じる捩じれを防ぐことができ、高い剛性が容易に得られて支持台の製作費を低減する効果がある。
【００３２】
また、この発明は以上説明したように、エレベーターの昇降路の下部に設置されて水平投影面において上記エレベーターのかごと重合して配置された巻上機、両端に上記エレベーターのかご及びつり合おもりがそれぞれ連結されて上記巻上機によって駆動される主索、上記昇降路に互いに離れて立設されて上記つり合おもりの昇降を案内するつり合おもり用レール、互いに離れて対面し長手が水平に配置されると共に幅方向が上記昇降路の底面に対して立設状態に配置された板体からなり、上記つり合おもり用レールの下端が連結され、かつ上記板体の相互間に上記つり合おもりに対向したつり合おもり用緩衝器が嵌合状態に配置された支持台と、この支持台の長手端部に設けられ一側が上記板体のそれぞれに結合されて、上記昇降路の底面よりも上方に配置され他側は上記巻上機要部の上側に対向して上記巻上機に作用する上向き荷重を支持する支持板とを備え、上記支持台の上記板体を、互いに離れて対面して配置された上記板体の両者の同側の長手端において、上記両者の一方の長手端に対して上記両者の他方の長手端が長手方向に離れて配置されたものとし、上記支持板を、上記両者の同側の長手端に対応する縁部が上記両者の長さの差に応じて傾斜して形成され、上記縁部によって支持される上記巻上機の駆動綱車の回転軸線が上記支持台の長手に対して９０°を超えた交差角を形成して配置されたものである。
【００３３】
これによって、支持台に対して支持板の傾斜縁部を介して巻上機が設置される。このため、巻上機の駆動綱車の回転軸線が支持台の長手に対して９０°を超えた交差角を形成して配置される。したがって、巻上機の反駆動綱車の端部と、かごの下降時のかご用吊り車との間に空間が形成され、この空間によって昇降路下部における保守等の作業を容易化する効果がある。
