Description

【０００１】
【発明の属する技術分野】
本発明は、かごをワイヤで吊り下げて上下するエレベータにおける駆動装置の固定構造に関するものである。
【０００２】
【従来の技術】
従来エレベータにおける駆動装置は一般にエレベータ昇降路内の上方にエレベータ昇降路とは別個に設けた機械室に設置して固定していた。この場合、機械室の床面や機械室に設置した取付け基台に軸受け部材を固着するとともに、モータ装置から突出した回転軸を軸受け部材の軸受け部に回転自在に挿入し且つ該モータ装置を固着してあった。そして、モータ装置のメンテナンスや修理や交換に当たっては、モータ装置の固着部分を取り外し、回転軸を軸受け部材から引き抜くことでモータ装置を取り外してメンテナンスや修理や交換をするようになっている。そして、メンテナンスや修理や交換後に、再びモータ装置を取付けるに当たっては、すでに固着して残置してある軸受け部材の軸受け部に回転軸を挿入し、モータ装置を取り外し前の固定箇所に再度固着するのであるが、この場合、モータ装置の固着位置の位置合わせが難しく、少しでもずれた位置に固着すると、軸受け部材の軸受けや回転軸やモータ装置の減速機等の軸受け部分等に無理な力が作用することになる。したがって、メンテナンスや修理や交換後におけるモータ装置の取付け作業が煩雑で面倒となるものである。
【０００３】
また、従来からエレベータ昇降路内の上部に駆動装置を配設して固着することでエレベータ昇降路とは別個の機械室を設けないものが例えば実公平４−５０２９７号公報などにより提案されている。このように別個の機械室を設けることなく、エレベータ昇降路内の上部に駆動装置を配設して固着するものの場合、別個の機械室を設けるもののように作業者が安全に乗れる床面がないため、上記のように、メンテナンスや修理や交換後におけるモータ装置の取付け作業が煩雑で面倒なものであるとよりいっそう作業がしにくくて作業時間がかかり、作業上好ましくないものである。
【０００４】
また、また、従来においては、エレベータ昇降路の内面を構成する建物躯体から取付け台を突出し、この取付け台に駆動装置を設置して固着しているが、取付け台は上下位置調整ができないものであり、したがって、かごを吊るワイヤの長さと、現場における各部の寸法誤差とを調整して最適の高さに固着するには現場において、建物躯体に取付け台を固着する作業に精度が要求され、この点でも現場作業が面倒となるものである。
【０００５】
【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、一対の軸受け部材の軸受け部によりモータ装置の回転軸を正確に安定して支持でき、また、モータ装置を取り外してメンテナンス、修理、交換をした後、簡単且つ確実にモータ装置の回転軸を支持させることができるエレベータ駆動装置の固定構造を提供することを主たる課題とし、また、エレベータ昇降路の他に別個に機械室を設ける必要がなく、しかも、取付け基台の上下位置を簡単に調整でき、また、安定して取付け基台を吊り下げることができ、更に、簡単な構造で取付け基台を吊り下げることができ、また、取付け基台をボルトにより上下位置調整自在に吊り下げるものにおいて上下調整してもボルトの下端部が取付け基台より長く突出することがなく邪魔にならないようにでき、また、取付け基台を上下位置調整自在に吊り下げるものでありながら取付け基台が振れないように安定化させることができ、また、簡単な構成で振れ止め手段を構成でき、また、かごを吊り下げるワイヤを移動させるためのシーブと調速機との位置関係を一定にでき施工が簡単となることを別の課題とするものである。
【０００６】
【課題を解決するための手段】
上記課題を解決するために本発明に係るエレベータ駆動装置の固定構造は、かご１をワイヤ２で吊り下げて上下するエレベータにおいて、エレベータ昇降路９の上部に位置する梁１０又は横架材１３から吊り部材１１により取付け基台３を高さ調整自在に吊り下げ、取付け基台３に連結材１３を固着し、連結材１７にボルト１８ｂ、ナット１８ｃで挟持材１８ｄを取付け、連結材１７と挟持材１８ｄとでかご１を上下方向に昇降自在にガイドするための昇降レール１２の上下方向の任意の位置を挟んだ状態でナット１８ｃを締め付けて挟着し、モータ本体部５ａと減速装置部５ｂとを備えたモータ装置５から側方に回転軸６を突設し、上記回転軸６にシーブ８を取付けると共に上記モータ装置６から回転軸６と直交方向に突出する支持材２３を取付け、上記取付け基台３に設けた一対の軸受け部材４の軸受け部７に上記モータ装置５から側方に突出した回転軸６のシーブ８の両側の部位を回転自在に挿入して２つの軸受け部７により２点で支持し、取付け基台３にモータ装置６から突出した支持材２３を回転軸６に対して直交する方向に取付け位置調整自在に支持して成ることを特徴とするものである。このような構成とすることで、モータ装置５の回転軸６を一対の軸受け部材４の軸受け部７により２点支持で安定して確実に支持できるものであり、しかも、このように一対の軸受け部７による２点支持で安定して回転軸６を支持するものにおいて、モータ装置６から突出した支持材２３が回転軸６に対して直交する方向に取付け位置調整自在に取付け基台３に支持されるので、取付け基台３へのモータ装置５の取付けが簡単に行えることになり、また、モータ装置５を取り外してメンテナンス、修理、交換をした後、再び取付けるに当たっては、モータ装置５の回転軸６を一対の軸受け部材４の軸受け部７に挿入して支持させ、モータ装置５は支持材２３を回転軸６に対して直交する方向に位置調整して取付け基台３に支持させるのみで、一対の軸受け部材４で回転自在に支持した回転軸６をモータ装置５で回転させた際に、モータ装置５が回転方向には回転しないように支持して回転軸６のみをスムーズに回転させてかごを吊り下げているワイヤを確実に移動させることができるものである。また、エレベータ昇降路９の上部に位置する梁１０又は横架材１３から吊り部材１１により取付け基台３を吊り下げてあるので、エレベータ昇降路９内の上部に軸受け部材４やモータ装置５からなる駆動装置を配置できて、エレベータ昇降路９の他に別個に機械室を設ける必要がなくて、スペース的に有利であるとともに、低コスト化が図れるものである。更に、エレベータ昇降路９の上部に位置する梁１０又は横架材１３から吊り部材１１により取付け基台３を高さ調整自在に吊り下げ、取付け基台３に連結材１３を固着し、連結材１７にボルト１８ｂ、ナット１８ｃで挟持材１８ｄを取付け、連結材１７と挟持材１８ｄとでかご１を上下方向に昇降自在にガイドするための昇降レール１２の上下方向の任意の位置を挟んだ状態でナット１８ｃを締め付けて挟着するので、取付け基台３の位置を上下方向に調整しても、昇降レール１２を利用して昇降レール１２の上下方向の任意の位置に連結材１７と挟持材１８ｄとで挟持して振れ止めでき、簡単な構成で取付け基台３を安定して吊下げることができる。
【０００７】
また、エレベータ昇降路９の上部に位置する建築物の梁１０から吊り部材１１により取付け基台３を高さ調整自在に吊り下げることが好ましい。このような構成とすることで、エレベータ昇降路９内の上部に軸受け部材４やモータ装置５からなる駆動装置を配置できて、エレベータ昇降路９の他に別個に機械室を設ける必要がないものであり、また、吊り部材１１による吊り下げ位置を調整することで取付け基台３の上下位置を簡単に調整することができるものであり、また、エレベータ昇降路９の上部に位置する建築物の梁１０から吊り下げ部材１１を吊り下げるので取付け基台３を安定して吊り下げることができるものである。
【０００８】
また、かご１を上下方向に昇降自在にガイドするための昇降レール１２の上端部に横架材１３を架設し、横架材１３から吊り部材１１により取付け基台３を高さ調整自在に吊り下げることが好ましい。このような構成とすることで、昇降レール１２が配置配置されるエレベータ昇降路９内の上部に軸受け部材４やモータ装置５からなる駆動装置を配置できて、エレベータ昇降路９の他に別個に機械室を設ける必要がないものであり、また、吊り部材１１による吊り下げ位置を調整することで取付け基台３の上下位置を簡単に調整することができるものであり、また、昇降レール１２の上端部に架設した横架材１３に吊り部材１１を吊り下げるので、昇降レール１２を利用して簡単な構造で取付け基台３を吊り下げることができるものである。
【０００９】
また、吊り部材１１がボルト１４により構成してあることが好ましい。このような構成とすることで、ボルト１４の雄ねじ部を利用して取付け基台３の上下方向の吊り下げ位置を簡単に調整することができるものである。
【００１０】
また、ボルト１４が上下に分割され、上ボルト１４ａの下部と下ボルト１４ｂの上部とが逆ねじの関係にあり、回転体１５の上部と下部とにそれぞれ逆ねじの関係となった雌ねじ筒１５ａ、１５ｂを設け、回転体１５の上部の雌ねじ筒１５ａに上ボルト１４ａの下部を螺合し、回転体１５の下部の雌ねじ筒１５ｂに下ボルト１４ｂの上部を螺合することが好ましい。このような構成とすることで、回転体１５を回転することで、ボルト１４の上下方向の長さ調整ができ、下ボルト１４ｂの取付け基台３への取付け位置を変えることなく取付け基台３の上下位置を調整できるものである。
【００１３】
また、取付け基台３にかご１の昇降速度が設定された速度を外れるとこれを検知してかご１の昇降を停止するための調速機１９を取付けることが好ましい。このような構成とすることで、かご１を吊り下げているワイヤ２を掛け回すシーブ８とかご１に接続するガバナロープ２１を掛け回す調速機１９の位置をあらかじめ工場などにおいて取付け基台３に対して相互に所定の位置関係となるように取付けることができるものである。
【００１４】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。
【００１５】
建物内には図１乃至図３に示すように上下階にわたって連続するエレベータ昇降路９が形成してある。本発明においてはこのエレベータ昇降路９内の上部に軸受け部材４やモータ装置５からなる駆動装置を配設した取付け基台３が配設してある。
【００１６】
取付け基台３は添付図面に示す実施形態においては一対の固定枠３ａを載設固着した基台プレート３ｂの脚部３ｃを中間枠３ｄに載設固着し、中間枠３ｄを下枠３ｅに載設固着して構成してある。取付け基台３の一対の固定枠３ａの上面部にはそれぞれ軸受け部材４の下部を載設してボルト２２により固着してある。取付け基台３に固着した一対の軸受け部材４は互いの軸受け部７の中心が同一軸芯上に位置するようにあらかじめ工場で組み立て時に調整して固着するものである。
【００１７】
モータ装置５はモータ本体部５ａと減速装置部５ｂとで構成してあり、減速装置部５ｂから側方に回転軸６が突出させてある。ここでモータ本体部５ａにおけるモータの回転を減速装置部５ｂで減速されて回転軸６が回転するようになっている。上記のモータ装置５は通常一般に市販されているものを使用することができるが、このモータ装置５に支持材２３が取付けてあり、支持材２３は回転軸６と直交する方向に突出している。
【００１８】
そして、モータ装置５の回転軸６は図５乃至図１３に示すように一対の軸受け部材４の対向する軸受け部７に挿入して両軸受け部７により２点で支持させてある。この場合、回転軸６にはかご１を吊り下げ用のワイヤ２を掛け回すためのシーブ８が取付けられるものであり、シーブ８は一対の軸受け部材４間に配置される。
【００１９】
ここで、本発明においては、上記のように両軸受け部７によりモータ装置５の回転軸６を２点で支持してあるので回転軸６の支持は安定して十分にできるが、この状態でモータ装置５のモータを回転して回転軸６を回転しようとしてもモータ装置５が回転してしまうものである。したがって、本発明においてはモータ装置５が回転しなようにモータ装置５を取付け基台３に支持する必要がある。この場合、取付け基台３に対して１対の軸受け部材４相互の位置合わせ固定に加え、モータ装置５を取付け基台３に対して固定して、一対の軸受け部材４とモータ装置５との３点固定をして、回転軸６の軸芯を一対の軸受け部７に同一芯上に合わせるということはきわめて精密な精度が要求され、芯合わせを精密にしながら固定する作業がきわめて難しいものである。
【００２０】
そこで、本発明においては、取付け基台３にモータ装置５を回転軸６に対して直交する方向に取付け位置調整自在に支持することで、一対の軸受け部７により支持する回転軸６を突設したモータ装置５の回転を防止するように取付け基台３に支持しながら取付け基台３の取付け位置を少なくとも回転軸６と直交する方向に調整して簡単に取付け基台３に支持させることができるようにしている。
【００２１】
図１４には取付け基台３にモータ装置５を回転軸６に対して直交する方向に取付け位置調整自在に支持する一例を示している。図１４においては取付け基台３の固定枠３ａの側面部に大径孔２４を設け、大径孔２４にブッシュ２５を大径孔２４の径方向に移動自在に遊嵌し、モータ装置５の支持材２３に設けた孔２３ａからボルト２６を挿入し、ブッシュ２５の孔２５ａに挿通してナット２７を締め付けることで支持材２３を固定枠３ａに取付けてあり、大径孔２４内にブッシュ２５が径方向に移動自在に遊嵌してあることで、支持材２３のボルト２６による取付け位置を調整できるようになっている。本実施形態では取付け位置の調整は回転軸６に対して直交する方向のみでなく、大径孔２４内においてこれよりも小径のブッシュ２５が移動できる範囲内で取付け位置を調整できるものである。そして、モータ装置５が回転しようとしてもブッシュ２５が大径孔２４の内壁面に当たることで、モータ装置５が回転しないように支持されるものである。
【００２２】
図１５には取付け基台３にモータ装置５を回転軸６に対して直交する方向に取付け位置調整自在に支持する他例を示している。図１５においては取付け基台３の固定枠３ａの側面部に回転軸６に対して直交する方向に長くなった長孔２８を設け、モータ装置５の支持材２３に設けた孔２３ａからボルト２６を挿入し、長孔２８を挿通してナット２７を締め付けることで支持材２３を固定枠３ａに取付けてあり、長孔２８内をボルト２６がスライドすることで支持材２３のボルト２６による取付け位置を回転軸６に対して直交する方向に調整自在となっている。そして、モータ装置５が回転しようとしてもボルト２６が長孔２８の内壁面に当たることで、モータ装置５が回転しないように支持されるものである。なお、本実施形態において、長孔２８内にブッシュを長孔２８の長手方向にスライド自在に嵌め込み、ブッシュにボルト２６を挿通してナット２７により取付けるようにしてもよいものである。
【００２３】
図１６には取付け基台３にモータ装置５を回転軸６に対して直交する方向に取付け位置調整自在に支持する更に他例を示している。本実施形態においては、取付け基台３の固定枠３ａの側面部に隙間２９ａを介して一対の回転防止用の当たり部２９を設けてあり、一対の回転防止用の当たり部２９間の隙間２９ａに支持材２３を回転軸６と直交する方向にスライド自在に嵌め込むことで取付けてあり、支持材２３が一対の回転防止用の当たり部２９間の隙間２９ａ内で回転軸６と直交する方向にスライドすることで、支持材２３の取付け基台３への取付け支持位置が調整されるものである。そして、モータ装置５が回転しようとしても支持材２３が回転防止用の当たり部２９に当たることで、モータ装置５が回転しないように支持されるものである。
【００２４】
上記のようにしてあらかじめ工場において一対の軸受け部材４、モータ装置５、シーブ８よりなる駆動装置３０を取付け基台３に取付けるものである。
【００２５】
そして、駆動装置３０を取付けた取付け基台３は現場に運ばれ、建物内に形成されたエレベータ昇降路９内の上部に配設されるものである。つまり、駆動装置３０をエレベータ昇降路９とは別の機械室に設置するのではなく、エレベータ昇降路９内の上部に配設して別の機械室を設けないようにするものである。
【００２６】
図５乃至図１３には駆動装置３０を取付けた取付け基台３をエレベータ昇降路９内の上部に配設する各例が示してある。図５、図６に示す実施形態、図９、図１０に示す実施形態においては、エレベータ昇降路９の上部に位置する建築物の梁１０から吊り部材１１により取付け基台３を高さ調整自在に吊り下げることで、駆動装置３０を取付けた取付け基台３をエレベータ昇降路９内の上部に配設する例が示してり、また、図７、図８に示す実施形態、図１１乃至図１３に示す実施形態にはかご１を上下方向に昇降自在にガイドするための昇降レール１２の上端部に横架材１３を架設し、横架材１３から吊り部材１１により取付け基台３を高さ調整自在に吊り下げた例が示してある。
【００２７】
また、図５，図６に示す実施形態、図７、図８に示す実施形態には吊り部材１１がボルト１４により構成してある例が示してある。本実施形態ではボルト１４に対するナット３１による締め付け位置を調整することで、エレベータ昇降路９内における駆動装置３０を取付けた取付け基台３の上下方向の高さを調整するようになっている。
【００２８】
また、図９、図１０に示す実施形態においては、ボルト１４を上ボルト１４ａと下ボルト１４ｂとに上下に分割してあり、この上ボルト１４ａの下部の雄ねじ部と下ボルト１４ｂの上部の雄ねじ部とは逆ねじの関係となっている。また、上ボルト１４ａの下部と、下ボルト１４ｂの上部は回転体１５の上部の雌ねじ筒１５ａと下部の雌ねじ部１６ｂととにぞれぞれ螺合してあり、回転体１５の上部の雌ねじ筒１５ａと下部の雌ねじ筒１５ｂとは逆ねじの関係となっている。そして、上ボルト１４ａの上端部が建築物の梁１０又は昇降レール１２の上端部に架設した横架材１３に取付けてあり、また、下ボルト１４ｂの下端部を取付け基台３に取付けてあり、回転体１５を回転することで取付け基台３の上下方向の位置調整をするようになっている。このものにおいては、下ボルト１４ｂの下端部の取付け基台３に対する位置が一定にできて、これにより取付け基台３の上下高さの調整をしても、下ボルト１４ｂの下端部が取付け基台３の下方に長く飛び出すことがなくて、かご１や後述のつり合い重り３２等が上昇する際の邪魔にならないようにできるものである。
【００２９】
また、図１１乃至図１３に示す実施形態には吊り部材１１がアングル材やＣチャンネル材やＨ型材等の鋼材により構成してある例を示している。このものにおいてはアングル材やＣチャンネル材やＨ型材等の鋼材により吊り下げることで取付け基台３が振れにくくて強固に吊り下げることができるものである。本実施形態においては鋼材よりなる吊り部材１１に上下方向に一定ピッチで取付け孔３３を設け、取付け基台３を吊り部材１１に対して任意の取付け孔３３を利用してボルト３４、ナットにより取付けることで取付け基台３の上下方向の位置調整をすることができるものである。
【００３０】
上記したいずれの実施形態においても、吊り部材１１により吊り下げた取付け基台３は振れ止め手段により振れ止めしてある。振れ止め手段は、例えば取付け基台３に連結材１７を取付けるとともに連結材１７の端部を、かご１を上下方向に昇降自在にガイドするための昇降レール１２の上下方向の任意の位置に挟持金具１８により取付けることで構成してある。挟持金具１８は例えば図１７に示すようなもので、取付け基台３に連結材１７を固着し、連結材１７の縦片１７ａにボルト１８ｂ、ナット１８ｃにより挟持材１８ｄを取付け、連結材１７の縦片１７ａと挟持材１８ｄとで昇降レール１２を挟持するものであり、ナット１８ｃを締め付けることで昇降レール１２の上下方向の任意の位置で挟着することができるようになっている。これにより取付け基台３の位置を上下方向に調整しても、昇降レール１２を利用して昇降レール１２の上下方向の任意の位置に挟持金具１８で挟持することで簡単な構成で上下位置の調整に応じて振れ止め手段により振れ止めできるものである。
【００３１】
エレベータ昇降路９内にはかご１を取付けたかごプラットホーム３５が昇降自在に配置されるものである。かごプラットホーム３５は下横枠体と縦枠体３５ａとよりなるＬ状をしており、下横枠体にかご１が載設して取付けてある。エレベータ昇降路９内の上部に配設された取付け基台３に取付けた駆動装置３０のシーブ８に掛け回されたワイヤ２の一端部がプラットホーム３５に固着され、また、ワイヤ２の他端部がつり合い重り３２が取付けてある。図４に示すように取付け基台３にはガイドローラ３７と振れ止めガイド３７ａとが設けてあり、昇降レール１２にガイドローラ３７が転動自在となっているとともに振れ止めガイド３７ａによって振れ止めしてある。また、つり合い重り３２には昇降ガイド部材３８が設けてあり、別の昇降レール１２に昇降ガイド部材３８が昇降自在に嵌めてあってつり合い重り３２の昇降のガイドをしている。
【００３２】
なお、図中４０はかご１に設けた開閉扉であり、４１は各階のエレベータホールの開口部に設けた各階用扉である。
【００３３】
ところで、かご１の昇降速度が設定された速度を外れるとこれを検知してかご１の昇降を停止するためのガバナと称される調速機１９が設けられるが、本発明においては、この調速機１９を図１に示すように取付け基台３の設定された位置にあらかじめ工場で取付けるものである。調速機１９には図４に示すようにかご１を載設するプラットホーム３５に設けたアーム４２に一端部を取付けたガバナロープ２１が掛け回され、このガバナロープ２１の下部を昇降レール１２に対して昇降する動滑車に掛け回すと共にガバナロープ２１の他端部をプラットホーム３５に取付けられるものである。そして、上記のように、工場であらかじめ取付け基台３の設定された位置に軸受け部材４を取付けて回転軸６を支持すると共に回転軸６にシーブ８を取付け、更に工場で取付け基台３の設定された位置に調速機１９を取付けることで、シーブ８と調速機１９の位置関係を設定された正確な位置関係にでき、これにより、現場でかご１にワイヤ２とガバナロープ２１とを取付けた場合（つまりかご１を載設するプラットホーム３５にワイヤ２とガバナロープ２１とを取付けた場合）、ワイヤ２とガバナロープ２１との位置関係を正確な位置関係とすることができるものである。
【００３４】
しかして、モータ装置５のモータを回転することで、一対の軸受け部材４によって２点で支持された回転軸６を回転し、シーブ８に巻回したワイヤ２を移動し、これによりかご１を昇降するのであるが、この場合、モータ装置５はモータ装置５を回転しても、取付け基台３に支持してあることで回転が阻止され、回転軸６のみが回転してスムーズにかご１を昇降することができるものである。
【００３５】
ところで、モータ装置５のメンテナンス、修理、交換に当たってモータ装置５を取り外す場合があるが、この場合には一対の軸受け部材４は取付け基台３に固着したままの状態で残し、モータ装置５のみを取付け基台３による支持を解除して取り外すものである。そして、モータ装置５のメンテナンス、修理、交換が終わると、モータ装置５を再び取付けるのであるが、この場合、モータ装置５の回転軸６を取付け基台３に所定の正確な位置関係で固着している一対の軸受け部材４の軸受け部７に挿入して支持させるものである。この場合、前述の取付けの際の説明と同様にモータ装置５は回転軸６に対して直交する方向に位置調整自在としてあることで、現場における取付けであるにもかかわらず簡単な位置調整で取付け基台３を回転方向には回転を阻止するように支持して取付けることができるものであり、モータ装置５の取付けが容易に行えるものである。このようにして取付けることで、一対の軸受け部材４で回転自在に支持した回転軸６をモータ装置５で回転させた際に、モータ装置５は回転方向には回転しないように支持して回転軸６のみをスムーズに回転させてかごを吊り下げているワイヤを確実に移動させることができるものである。
【００３６】
【発明の効果】
上記のように本発明の請求項１記載の発明にあっては、かごをワイヤで吊り下げて上下するエレベータにおいて、エレベータ昇降路の上部に位置する梁又は横架材から吊り部材により取付け基台を高さ調整自在に吊り下げ、取付け基台に連結材を固着し、連結材にボルト、ナットで挟持材を取付け、連結材と挟持材とでかごを上下方向に昇降自在にガイドするための昇降レールの上下方向の任意の位置を挟んだ状態でナットを締め付けて挟着し、モータ本体部と減速装置部とを備えたモータ装置から側方に回転軸を突設し、上記回転軸にシーブを取付けると共に上記モータ装置から回転軸と直交方向に突出する支持材を取付け、上記取付け基台に設けた一対の軸受け部材の軸受け部に上記モータ装置から側方に突出した回転軸のシーブの両側の部位を回転自在に挿入して２つの軸受け部により２点で支持し、取付け基台にモータ装置から突出した支持材を回転軸に対して直交する方向に取付け位置調整自在に支持してあるので、モータ装置の回転軸を一対の軸受け部材の軸受け部により２点支持で安定して確実に支持するものにおいて、取付け基台へのモータ装置の取付けが簡単に行えるものであり、また、モータ装置を取り外してメンテナンス、修理、交換をした後、再び取付けるに当たって、モータ装置の回転軸を一対の軸受け部材の軸受け部に挿入して支持させ、モータ装置は回転軸と直交方向に突出する支持材を回転軸に対して直交する方向に位置調整して取付け基台に支持させるのみで、簡単な構成でモータ装置の取付けができるとともに一対の軸受け部材で回転自在に支持した回転軸をモータ装置で回転させた際に、モータ装置が回転方向には回転しないように支持して回転軸のみをスムーズに回転させてかごを吊り下げているワイヤを確実に移動させることができるものである。また、エレベータ昇降路の上部に位置する梁又は横架材から吊り部材により取付け基台を吊り下げてあるので、エレベータ昇降路内の上部に軸受け部材やモータ装置からなる駆動装置を配置できて、エレベータ昇降路の他に別個に機械室を設ける必要がなくて、スペース的に有利であるとともに、低コスト化が図れるものである。更に、エレベータ昇降路の上部に位置する梁又は横架材から吊り部材により取付け基台を高さ調整自在に吊り下げ、取付け基台に連結材を固着し、連結材にボルト、ナットで挟持材を取付け、連結材と挟持材とでかごを上下方向に昇降自在にガイドするための昇降レールの上下方向の任意の位置を挟んだ状態でナットを締め付けて挟着するので、取付け基台の位置を上下方向に調整しても、昇降レールを利用して昇降レールの上下方向の任意の位置に連結材と挟持材とで挟持して振れ止めでき、簡単な構成で取付け基台を安定して吊下げることができる。
【００３７】

【００３９】

BACKGROUND OF THE INVENTION
The present invention relates to a structure for fixing a drive device in an elevator that lifts and lowers a car with a wire.
[0002]
[Prior art]
Conventionally, a drive device in an elevator is generally installed and fixed in a machine room provided separately from the elevator hoistway above the elevator hoistway. In this case, the bearing member is fixed to the floor surface of the machine room or the mounting base installed in the machine room, and the rotating shaft protruding from the motor device is rotatably inserted into the bearing portion of the bearing member and the motor device is fixed. It was. In maintenance, repair, or replacement of the motor device, the motor device is removed for maintenance, repair, or replacement by removing the fixed portion of the motor device and pulling out the rotating shaft from the bearing member. And when installing the motor device again after maintenance, repair or replacement, insert the rotating shaft into the bearing part of the bearing member that has already been fixed and left, and fix the motor device again at the fixed place before removal. However, in this case, it is difficult to align the fixing position of the motor device, and if it is fixed to a slightly deviated position, an unreasonable force is applied to the bearing portion of the bearing member, the rotating shaft, the bearing portion of the reduction gear of the motor device, etc. Will do. Therefore, the installation work of the motor device after maintenance, repair or replacement is complicated and troublesome.
[0003]
Further, for example, Japanese Utility Model Publication No. 4-50297 proposes a machine device that is not provided with a machine room separate from an elevator hoistway by disposing and fixing a driving device on the upper part of the elevator hoistway. . In the case where the drive device is arranged and fixed on the upper part in the elevator hoistway without providing a separate machine room, there is no floor surface on which an operator can safely ride as in the case of providing a separate machine room. For this reason, as described above, if the work of attaching the motor device after maintenance, repair, or replacement is complicated and troublesome, it is more difficult to perform the work and takes a long time, which is not preferable in terms of work.
[0004]
In addition, conventionally, a mounting base protrudes from the building frame that forms the inner surface of the elevator hoistway, and a drive device is installed and secured to this mounting base. However, the mounting base cannot be adjusted vertically. Therefore, in order to adjust the length of the wire that suspends the car and the dimensional error of each part at the site and fix it to the optimum height, accuracy is required for the operation of fixing the mounting base to the building frame at the site, In this respect, the field work is troublesome.
[0005]
[Problems to be solved by the invention]
The present invention has been made in view of the above points, and the rotation shaft of the motor device can be accurately and stably supported by the bearing portions of the pair of bearing members, and the motor device can be removed for maintenance, repair, and replacement. After that, the main object is to provide an elevator drive device fixing structure that can easily and reliably support the rotating shaft of the motor device, and there is no need to provide a separate machine room in addition to the elevator hoistway. In addition, the vertical position of the mounting base can be easily adjusted, the mounting base can be stably suspended, and the mounting base can be suspended with a simple structure. Even if the base is suspended by a bolt so that the vertical position can be adjusted freely, the lower end of the bolt does not protrude longer than the mounting base so that it does not get in the way, Although the mounting base is suspended so that the vertical position can be adjusted, the mounting base can be stabilized so that it does not swing, and the steadying means can be configured with a simple configuration, and the basket can be suspended. Another problem is that the positional relationship between the sheave for moving the wire to be lowered and the speed governor can be made constant and the construction is simplified.
[0006]

The support member 23 is supported at two points, and the support member 23 protruding from the motor device 6 is supported on the mounting base 3 in a direction orthogonal to the rotation shaft 6 so that the mounting position can be adjusted. With such a configuration, the rotating shaft 6 of the motor device 5 can be stably and reliably supported by the bearing portions 7 of the pair of bearing members 4 with two-point support, and in this way, the pair of bearings Supporting the rotating shaft 6 with two-point support by the portion 7, the support member 23 protruding from the motor device 6 is supported on the mounting base 3 so that the mounting position can be adjusted in the direction orthogonal to the rotating shaft 6. Therefore, the motor device 5 can be easily mounted on the mounting base 3, and the motor device 5 is rotated when the motor device 5 is removed, maintained, repaired, and replaced, and then mounted again. The shaft 6 is inserted into and supported by the bearing portions 7 of the pair of bearing members 4, and the motor device 5 merely supports the mounting base 3 by adjusting the position of the support member 23 in the direction orthogonal to the rotating shaft 6. , When the rotating shaft 6 rotatably supported by the pair of bearing members 4 is rotated by the motor device 5, the motor device 5 is supported so as not to rotate in the rotating direction, and only the rotating shaft 6 is smoothly rotated. The wire that suspends the car can be moved reliably. In addition, since the mounting base 3 is suspended from the beam 10 or the horizontal member 13 positioned at the upper part of the elevator hoistway 9 by the suspension member 11, the bearing member 4 and the motor device 5 are disposed on the upper part in the elevator hoistway 9.

It is preferable to lower. By adopting such a configuration, the drive device including the bearing member 4 and the motor device 5 can be arranged at the upper part in the elevator hoistway 9 where the hoisting rails 12 are arranged, and separately from the elevator hoistway 9. It is not necessary to provide a machine room, and the vertical position of the mounting base 3 can be easily adjusted by adjusting the suspension position of the suspension member 11. Since the suspension member 11 is suspended from the horizontal member 13 installed on the upper end, the mounting base 3 can be suspended with a simple structure using the lifting rail 12.
[0009]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.
[0015]
As shown in FIGS. 1 to 3, an elevator hoistway 9 that is continuous over the upper and lower floors is formed in the building. In the present invention, a mounting base 3 in which a driving device including a bearing member 4 and a motor device 5 is disposed is disposed in an upper portion of the elevator hoistway 9.
[0016]
In the embodiment shown in the accompanying drawings, the mounting base 3 has the legs 3c of the base plate 3b on which the pair of fixed frames 3a are mounted and fixed, mounted and fixed on the intermediate frame 3d, and the intermediate frame 3d mounted on the lower frame 3e. It is constructed and fixed. The lower part of the bearing member 4 is mounted on the upper surface part of the pair of fixed frames 3 a of the mounting base 3 and fixed by bolts 22. The pair of bearing members 4 fixed to the mounting base 3 are adjusted and fixed in advance at the time of assembly in the factory so that the centers of the mutual bearing portions 7 are located on the same axis.
[0017]
The motor device 5 is composed of a motor main body 5a and a speed reducing device 5b, and a rotating shaft 6 is protruded laterally from the speed reducing device 5b. Here, the rotation of the motor in the motor main body 5a is decelerated by the speed reducer 5b so that the rotary shaft 6 rotates. As the motor device 5, a commercially available one can be used. However, a support material 23 is attached to the motor device 5, and the support material 23 projects in a direction perpendicular to the rotation shaft 6.
[0018]
The rotating shaft 6 of the motor device 5 is inserted into the opposing bearing portions 7 of the pair of bearing members 4 and supported by the two bearing portions 7 at two points as shown in FIGS. In this case, a sheave 8 for attaching the wire 1 for hanging the car 1 to the rotating shaft 6 is attached, and the sheave 8 is disposed between the pair of bearing members 4.
[0019]
Here, in the present invention, since the rotating shaft 6 of the motor device 5 is supported at two points by the both bearing portions 7 as described above, the rotating shaft 6 can be supported stably and sufficiently. Even if it is going to rotate the rotating shaft 6 by rotating the motor of the motor apparatus 5, the motor apparatus 5 will rotate. Therefore, in the present invention, it is necessary to support the motor device 5 on the mounting base 3 so that the motor device 5 does not rotate. In this case, in addition to the positioning and fixing of the pair of bearing members 4 to the mounting base 3, the motor device 5 is fixed to the mounting base 3, and the pair of bearing members 4 and the motor device 5 are fixed. Fixing three points and aligning the axis of the rotating shaft 6 with the pair of bearings 7 on the same core requires extremely precise accuracy, and it is extremely difficult to perform the fixing while accurately aligning the centers. is there.
[0020]
Therefore, in the present invention, the motor device 5 is supported on the mounting base 3 in a direction orthogonal to the rotating shaft 6 so that the mounting position can be adjusted, so that the rotating shaft 6 supported by the pair of bearing portions 7 is projected. The mounting position of the mounting base 3 is adjusted at least in the direction orthogonal to the rotation shaft 6 while being supported on the mounting base 3 so as to prevent the motor device 5 from rotating, and can be easily supported on the mounting base 3. I can do it.
[0021]
FIG. 14 shows an example in which the motor device 5 is supported on the mounting base 3 so that the mounting position can be adjusted in a direction orthogonal to the rotating shaft 6. In FIG. 14, a large diameter hole 24 is provided in the side surface portion of the fixed frame 3 a of the mounting base 3, and a bush 25 is loosely fitted in the large diameter hole 24 so as to be movable in the radial direction of the large diameter hole 24. Bolts 26 are inserted from holes 23 a provided in the support member 23, inserted into the holes 25 a of the bush 25 and tightened with nuts 27, so that the support member 23 is attached to the fixed frame 3 a, and the bush 25 is placed in the large-diameter hole 24. Is loosely movably fitted in the radial direction so that the mounting position of the support member 23 by the bolt 26 can be adjusted. In this embodiment, the attachment position can be adjusted not only in the direction orthogonal to the rotating shaft 6 but also within the range in which the bush 25 having a smaller diameter can move within the large diameter hole 24. And even if the motor device 5 tries to rotate, the bush 25 hits the inner wall surface of the large-diameter hole 24 so that the motor device 5 is supported so as not to rotate.
[0022]
FIG. 15 shows another example in which the motor device 5 is supported on the mounting base 3 in a direction orthogonal to the rotation shaft 6 so that the mounting position can be adjusted. In FIG. 15, a long hole 28 that is elongated in a direction perpendicular to the rotation shaft 6 is provided on the side surface of the fixed frame 3 a of the mounting base 3, and the bolt 26 extends from the hole 23 a provided in the support member 23 of the motor device 5. The support material 23 is attached to the fixed frame 3a by inserting the long hole 28 and tightening the nut 27, and the mounting position of the support material 23 by the bolt 26 by sliding the bolt 26 in the long hole 28. Is adjustable in a direction perpendicular to the rotation axis 6. And even if the motor apparatus 5 tries to rotate, the bolt 26 hits the inner wall surface of the long hole 28, so that the motor apparatus 5 is supported so as not to rotate. In the present embodiment, the bush may be fitted into the long hole 28 so as to be slidable in the longitudinal direction of the long hole 28, and the bolt 26 may be inserted into the bush and attached by the nut 27.
[0023]
FIG. 16 shows still another example in which the motor device 5 is supported on the mounting base 3 so that the mounting position can be adjusted in a direction orthogonal to the rotating shaft 6. In the present embodiment, a pair of rotation-preventing contact portions 29 are provided on the side surface portion of the fixed frame 3a of the mounting base 3 via a clearance 29a, and the clearance 29a between the pair of rotation-preventing contact portions 29 is provided. The support member 23 is slidably fitted in a direction orthogonal to the rotation shaft 6, and the support member 23 is perpendicular to the rotation shaft 6 in the gap 29 a between the pair of rotation-preventing contact portions 29. The mounting support position of the support member 23 on the mounting base 3 is adjusted by sliding to. And even if the motor apparatus 5 tries to rotate, the motor apparatus 5 is supported so that it does not rotate because the support material 23 contacts the contact part 29 for rotation prevention.
[0024]
As described above, the drive device 30 including the pair of bearing members 4, the motor device 5, and the sheave 8 is attached to the attachment base 3 in advance in the factory.
[0025]
And the mounting base 3 which attached the drive device 30 is carried to the spot, and is arrange | positioned by the upper part in the elevator hoistway 9 formed in the building. That is, the drive device 30 is not installed in a machine room separate from the elevator hoistway 9 but is arranged in the upper part of the elevator hoistway 9 so that another machine room is not provided.
[0026]
FIGS. 5 to 13 show examples in which the mounting base 3 to which the driving device 30 is attached is arranged in the upper part of the elevator hoistway 9. In the embodiment shown in FIGS. 5 and 6, and the embodiment shown in FIGS. 9 and 10, the height of the mounting base 3 can be adjusted by the suspension member 11 from the beam 10 of the building located at the upper part of the elevator hoistway 9. FIG. 7 shows an example in which the mounting base 3 to which the drive device 30 is attached is arranged at the upper part in the elevator hoistway 9 by hanging it on the embodiment, FIG. 11 to FIG. In the embodiment shown in FIG. 13, a horizontal member 13 is installed on the upper end portion of the elevating rail 12 for guiding the car 1 so that it can be raised and lowered in the vertical direction. An example in which the height is freely adjustable is shown.
[0027]
The embodiment shown in FIGS. 5 and 6 and the embodiment shown in FIGS. 7 and 8 show an example in which the suspension member 11 is constituted by a bolt 14. In the present embodiment, the height in the vertical direction of the mounting base 3 to which the driving device 30 is attached in the elevator hoistway 9 is adjusted by adjusting the tightening position of the bolt 14 by the nut 31.
[0028]
Further, in the embodiment shown in FIGS. 9 and 10, the bolt 14 is divided into an upper bolt 14a and a lower bolt 14b in the vertical direction, and a male screw portion below the upper bolt 14a and a male screw above the lower bolt 14b. The part has a reverse screw relationship. Further, the lower part of the upper bolt 14a and the upper part of the lower bolt 14b are screwed into the female screw cylinder 15a on the upper part of the rotating body 15 and the female screw part 16b on the lower part, respectively. The cylinder 15a and the lower female screw cylinder 15b are in a reverse screw relationship. The upper end of the upper bolt 14a is attached to the horizontal member 13 constructed on the upper end of the building beam 10 or the lifting rail 12, and the lower end of the lower bolt 14b is attached to the attachment base 3. The position of the mounting base 3 in the vertical direction is adjusted by rotating the rotating body 15. In this case, the position of the lower end portion of the lower bolt 14b with respect to the mounting base 3 can be made constant, so that the lower end portion of the lower bolt 14b is attached to the mounting base even if the vertical height of the mounting base 3 is adjusted. It does not jump out below the table 3 for a long time, so that it does not interfere with the raising of the car 1, the balance weight 32 and the like described later.
[0029]
Further, the embodiment shown in FIGS. 11 to 13 shows an example in which the suspension member 11 is made of a steel material such as an angle material, a C channel material, or an H-shaped material. In this case, the mounting base 3 is not easily shaken by being suspended by a steel material such as an angle material, a C channel material, or an H-shaped material, and can be firmly suspended. In the present embodiment, mounting holes 33 are provided at a constant pitch in the vertical direction in the suspension member 11 made of steel, and the mounting base 3 is attached to the suspension member 11 by using bolts 34 and nuts using an arbitrary mounting hole 33. Thus, the vertical position of the mounting base 3 can be adjusted.
[0030]
In any of the above-described embodiments, the mounting base 3 suspended by the suspension member 11 is steady by the steadying means. The steadying means, for example, attaches the connecting member 17 to the mounting base 3 and holds the end of the connecting member 17 at an arbitrary position in the vertical direction of the lifting rail 12 for guiding the car 1 so that it can be lifted up and down. It is configured by being attached by a metal fitting 18. For example, the clamping metal member 18 is as shown in FIG. 17, the connecting member 17 is fixed to the mounting base 3, and the holding member 18 d is attached to the vertical piece 17 a of the connecting member 17 by bolts 18 b and nuts 18 c. The elevating rail 12 is clamped by the vertical piece 17a and the clamping material 18d, and can be clamped at any position in the vertical direction of the elevating rail 12 by tightening the nut 18c. As a result, even if the position of the mounting base 3 is adjusted in the vertical direction, the vertical position of the vertical position can be adjusted with a simple configuration by using the lifting rail 12 to hold it at any position in the vertical direction of the lifting rail 12 with the clamping bracket 18. According to the adjustment, the steadying means can prevent the steadying.
[0031]
A car platform 35 to which the car 1 is attached is disposed in the elevator hoistway 9 so as to be raised and lowered. The car platform 35 has an L shape composed of a lower horizontal frame and a vertical frame 35a, and the car 1 is mounted on and attached to the lower horizontal frame. One end of the wire 2 wound around the sheave 8 of the driving device 30 attached to the attachment base 3 disposed at the upper part in the elevator hoistway 9 is fixed to the platform 35, and the other end of the wire 2 is attached. A counterweight 32 is attached. As shown in FIG. 4, the mounting base 3 is provided with a guide roller 37 and an anti-sway guide 37a. The guide roller 37 can roll on the elevating rail 12 and is anti-swayed by the anti-sway guide 37a. It is. Further, the counterweight 32 is provided with an elevating guide member 38, and the elevating guide member 38 is fitted to another elevating rail 12 so as to be movable up and down to guide the counterweight 32.
[0032]
In the figure, 40 is an open / close door provided in the car 1, and 41 is a door for each floor provided in the opening of the elevator hall on each floor.
[0033]
By the way, there is provided a governor 19 called a governor for detecting when the raising / lowering speed of the car 1 deviates from the set speed and stopping the raising / lowering of the car 1. As shown in FIG. 1, the speed machine 19 is mounted in advance at a set position of the mounting base 3 at a factory. As shown in FIG. 4, a governor rope 21 having one end attached to an arm 42 provided on a platform 35 on which the car 1 is mounted is hung around the governor 19. The other end of the governor rope 21 is attached to the platform 35 while being hung around a moving pulley that moves up and down. Then, as described above, the bearing member 4 is attached at a preset position of the mounting base 3 at the factory to support the rotating shaft 6 and the sheave 8 is attached to the rotating shaft 6. Further, the mounting base 3 of the mounting base 3 is installed at the factory. By attaching the speed governor 19 to the set position, the positional relationship between the sheave 8 and the speed governor 19 can be set to an accurate positional relationship. As a result, the wire 2 and the governor rope 21 are connected to the car 1 at the site. When attached (that is, when the wire 2 and the governor rope 21 are attached to the platform 35 on which the car 1 is mounted), the positional relationship between the wire 2 and the governor rope 21 can be made an accurate positional relationship.
[0034]
Thus, by rotating the motor of the motor device 5, the rotating shaft 6 supported at two points by the pair of bearing members 4 is rotated, and the wire 2 wound around the sheave 8 is moved, whereby the car 1 is moved. In this case, even if the motor device 5 rotates, the motor device 5 is supported by the mounting base 3 to prevent rotation, and only the rotating shaft 6 rotates to smoothly move the car 1. Can be moved up and down.
[0035]
By the way, the motor device 5 may be removed for maintenance, repair, or replacement of the motor device 5. In this case, the pair of bearing members 4 remain attached to the mounting base 3, and only the motor device 5 is left. The support by the mounting base 3 is released and removed. When the maintenance, repair, and replacement of the motor device 5 are completed, the motor device 5 is mounted again. In this case, the rotating shaft 6 of the motor device 5 is fixed to the mounting base 3 with a predetermined accurate positional relationship. The pair of bearing members 4 are inserted into and supported by the bearing portions 7. In this case, the position of the motor device 5 can be adjusted in the direction orthogonal to the rotating shaft 6 in the same manner as described above for mounting, so that it can be mounted with simple positioning regardless of mounting on the site. The base 3 can be supported and attached so as to prevent rotation in the rotational direction, and the motor device 5 can be easily attached. By mounting in this manner, when the rotating shaft 6 rotatably supported by the pair of bearing members 4 is rotated by the motor device 5, the motor device 5 is supported so as not to rotate in the rotating direction. Only the wire 6 is smoothly rotated, and the wire hanging the car can be moved reliably.
