【発明の属する技術分野】
本発明は、機械室レスエレベーター用保守点検装置に関するものである。
【0002】
【従来の技術】
従来、機械室レスエレベーターでは、昇降路内底に駆動用巻上機を設け、かつ、昇降路側壁に各種のエレベーター制御を司る制御盤を取り付けるようにしていた。しかも、万一、昇降路内底に雨水等が流れ込んだ場合の対策として、駆動用巻上機を防水構造にするとともに、制御盤を最下階乗場の床面より上方の昇降路内壁面部分に取り付けるようにしていた(例えば、特許文献1参照。)。

【特許文献1】
特開2002−293486号公報
(段落番号0002〜0005、第3図)
【0004】
【発明が解決しようとする課題】
上記従来例では、制御盤は、最下階乗場の床面より上方の昇降路内壁面部分に位置し、しかも、各種のエレベーター制御を司る多数の電気部品等を縦方向に並べているためにその制御盤の外観形状が縦長となってしまうので、その制御盤の高さ位置が高くなってしまい、保守員が昇降路内底に立ったままで制御盤の保守点検をすることができないという問題点があった。そこで、昇降路内に点検作業台を設置することが提案されたが、その提案には、保守点検作業中の保守員が昇降路内にいる間に駆動用巻上機をうっかり作動させてしまうとその保守員が危険な状態に晒されたり、あるいは点検作業台を昇降路内に設置したままで駆動用巻上機をうっかり作動させてしまうと点検作業台や乗りかごなどを破損させてしまうという問題点があった。
【0005】
本発明の目的は、上記の問題点を簡単な構成によって解決しえる機械室レスエレベーター用保守点検装置を提供するにある。
【0006】
【課題を解決するための手段】
上記目的は、昇降路内底側に駆動用巻上機を設けるとともに、最下階乗場の床面より上方の昇降路壁面に縦長の制御盤を取り付けてなる機械室レスエレベーターであって、その制御盤を保守点検する際に用いられる機械室レスエレベーター用保守点検装置において、昇降路内壁面に対して一端が回動可能に設けられて前記制御盤の下方に収納される点検作業台と、この点検作業台上に設けた折り畳み自在の転落防止柵と、前記点検作業台を水平に保持するための作業固定棒と、水平に保持された状態の前記点検作業台に乗り降りするための脱着式梯子と、前記点検作業台の前記制御盤下方への収納が解除されると前記駆動用巻上機の起動回路を開放する開放手段とから構成したことにより、達成される。
【0007】
かかる構成によれば、点検作業台を水平に保持するために、その点検作業台を回動させると、開放手段によって駆動用巻上機の起動回路が自動的に開放されて、再び、制御盤の下方にその点検作業台が収納されるまで駆動用巻上機の起動回路が開放された状態を維持する。そして、点検作業台が制御盤の下方に収納されると、駆動用巻上機の起動回路が閉成されて乗りかごや釣合重りの制御が可能な状態となる。したがって、点検作業台が制御盤の下方に収納されない限り、乗りかごや釣合重りを動かそうとしても、動かすことができないため、点検作業台を昇降路内で水平に保持したままに放置するなどの放置忘れを気づかせられるので、その放置状態のままで駆動用巻上機が作動することにより点検作業台に乗りかごが衝突してしまうことなどを阻止できる。また、点検作業台が制御盤の下方に収納されない状態で、保守員が昇降路内にいても、駆動用巻上機が作動しないので、その保守員が危険な状態に晒されることがない。
【0008】
【発明の実施の形態】
以下、本発明を具体化した実施形態を、図1から図4にしたがって説明する。図1は機械室レスエレベーターの概略構造説明図、図2は図1の機械室レスエレベーターに制御盤の保守点検装置を設置した状態を示す概略構造説明図、図3は図2の保守点検装置における点検作業台に保守員が乗った状態を示す概略構造説明図、図4は要部分の概略電気回路図である。
【0009】
図1において、機械室レスエレベーター1は、昇降路2と、乗りかご3と、釣合重り4と、主ロープ5と、制御盤6と、駆動用巻上機7を具備している。乗りかご3及び釣合重り4は、主ロープ5を駆動用巻上機7により移動させることで、昇降するようにしてある。制御盤6は、昇降路2の最下階乗場2Aの床面8より上方の昇降路2の内壁面2Bに取り付けられる。駆動用巻上機7は、昇降路2の内底2Cに設けられる。制御盤6は、縦長の形状にしてある。制御盤6の下面6Aは、最下階乗場2Aの床面8より上方に位置している。
【0010】
機械室レスエレベーター1の制御盤2を保守点検する際に用いられる保守点検装置9は、図2及び図3に示すように、昇降路2の内壁面2Bに対して一端が回動可能に設けられて制御盤2の下方に収納される点検作業台10と、この点検作業台10上に設けた折り畳み自在の転落防止柵11と、点検作業台10を水平に保持するための作業固定棒12と、水平に保持された状態の点検作業台10に乗り降りするための脱着式梯子13と、点検作業台10が制御盤2の下方に収納されるのが解除されると駆動用巻上機7の起動回路15を自動的に開放する開放手段14とを、少なくとも具備している。保守点検装置9は、図2に示すように、機械室レスエレベーター1の通常運転状態のときには折り畳まれて制御盤2の下方に収納される。
【0011】
作業固定棒12は、折り畳み自在な構造にしてある。脱着式梯子13は、点検作業台10を水平に保持された状態のときにその点検作業台10に、脱着自在に取り付けられる。脱着式梯子13を点検作業台10に取り付けない場合には、図2に示すように、昇降路2の内底2Cの隅部にその脱着式梯子13が倒して置かれる。
【0012】
開放手段14は、点検作業台10を昇降路2の内壁面2Bから離れる方向に回動すると駆動用巻上機7の起動回路15を「切」状態とし、かつ、点検作業台10が昇降路2の内壁面2Bに近づく方向に回動して点検作業台10が昇降路2の内壁面2Bに近接若しくは当接すると駆動用巻上機7の起動回路15を「入り」状態とする開閉器14Aからなっている(図4を参照)。
【0013】
開閉器14Aの接点は、図2の状態では切れ、かつ、図3の状態では入るようにしてある。すなわち、点検作業台10を回動させて昇降路2の内壁面2Bから離すと開閉器14Aの接点が切れて駆動用巻上機7の起動回路15が開放し、かつ、逆に点検作業台10を回動させて昇降路2の内壁面2Bに近接させると開閉器14Aの接点が入り駆動用巻上機7の起動回路15が閉成する。
【0014】
上記本実施形態の保守点検装置9を用いた保守点検作業は、
(1)始めに、安全のため、保守員Aが、機械室レスエレベーター1の主電源スイッチ(図示せず)を開放する。
【0015】
(2)次に、昇降路2の内底2Cに降りた保守員Aが保守点検装置9の転落防止柵11を展開させて点検作業台10の自由端部分に組立固定する。
【0016】
(3)次に、保守点検装置9の点検作業台10を、昇降路2の内壁面2Bから離れる方向に回動させた後、図3に示すように、作業固定棒12により点検作業台10を水平に支持する。この場合、点検作業台10が昇降路2の内壁面2Bから所定距離離れると、開放手段14の開閉器14Aが自動的に切れて、駆動用巻上機7の起動回路15が開放状態となる。
【0017】
(4)次に、水平に支持された点検作業台10に、脱着式梯子13を、図3に示すように、取付固定する。
【0018】
(5)次に、点検作業台10に固定された脱着式梯子13を利用して保守員Aが点検作業台10に乗り、制御盤6の保守点検作業を行う。
【0019】
(6)次に、制御盤6の保守点検作業が終了したならば、保守員Aは、点検作業台10から脱着式梯子13を利用して昇降路2の内底2Cに降り、その後、その保守員Aが脱着式梯子13を点検作業台10から取外して、その脱着式梯子13を昇降路2の内底2Cの隅に置く。
【0020】
(7)次に、昇降路2の内底2Cに降りた保守員Aは、作業固定棒12による点検作業台10の支持状態を除去して、点検作業台10を回動させてその点検作業台10を制御盤6の下方に収納する。この時、点検作業台10が昇降路2の内壁面2Bに所定距離まで近づくと、開放手段14の開閉器14Aが自動的に入り、駆動用巻上機7の起動回路15が閉成状態となる。その後、転落防止柵11を折り畳めば、保守点検装置9が図2の状態となり、制御盤6の保守点検作業は、終了する。
【0021】
以上、詳述した上記本実施形態例によれば下記(A)から(D)に示す効果がある。
【0022】
(A)点検作業台10を水平に支持するために、その点検作業台10を昇降路2の内壁面2Bから離れる方向に回動させると、開放手段14の開閉器14Aが自動的に切れて、駆動用巻上機7の起動回路15が開放状態となるので、保守点検装置9の組立作業中及び点検作業台10に上がって制御盤6の保守点検作業を実行中に、機械室レスエレベーター1の主電源スイッチを切り忘れたとしても、駆動用巻上機7が作動して乗りかご3あるいは釣合重り4が下降してくるようなことがなく、安全である。
【0023】
(B)縦長の制御盤を、最下階乗場の床面より上方の昇降路壁面に取り付けても、保守員Aが点検作業台10に上がって、制御盤6の保守点検作業を行うことで、その保守点検作業を難なく行うことができる。
【0024】
(C)最下階乗場の床面より上方に、制御盤6の下面が位置しているので、万一、台風などにより昇降路2内に雨水が流れ込み、昇降路2のピット内一杯に雨水が溜まったとしても、その雨水は、最下階乗場2Aの床面8側に流れてしまい、制御盤6が昇降路2のピット内に溜まった雨水で濡れることがない。
【0025】
(D)制御盤6の保守点検作業が終了して、保守点検装置9の点検作業台10を、制御盤6の下方に収納すれば、自動的に駆動用巻上機7の起動回路15が閉成されるので、便利である。
【0026】
(E)点検作業台10が制御盤6の下方に収納されない限り、乗りかご3や釣合重り4を動かそうとしても、動かすことができないため、点検作業台10を昇降路2内で水平に保持したままに放置するなどの放置忘れを気づかせられるので、その放置状態のままで駆動用巻上機7が作動することにより点検作業台10に乗りかご3が衝突してしまうことなどを阻止できる。また、点検作業台10が制御盤6の下方に収納されない状態で、保守員Aが昇降路2内にいても、駆動用巻上機7が作動しないので、その保守員Aが危険な状態に晒されることがない。
【0027】
【発明の効果】
以上のように、本発明によれば、昇降路内に点検作業台を水平に保持した状態のままで駆動用巻上機をうっかり作動させることを防止して、点検作業台や乗りかごなどを破損させてしまうことを阻止できる構造簡単な機械室レスエレベーター用保守点検装置がえられた。
