Description

【０００１】
【発明の属する技術分野】
この発明は、機械室レスエレベータの保守方法に関し、特にスペース削減の為、巻上機と制御盤とが近づいて設置されている機械室レスエレベータの巻上機保守方法に関するものである。
【０００２】
【従来の技術】
多くのエレベータは、利用者が乗る乗かごとつり合い重りとを巻上機に巻掛けたつりロープで連結し、つり合い重りとの重量バランスをとって乗かごを昇降駆動するように構成されている。これをロープ式エレベータと呼ぶ。ところで、このようなエレベータにおいては、エレベータを設置する建物内のスペースとして、乗かごが昇降する昇降路と、巻上機と制御盤を収納する機械室とが必要であり、この機械室は通常建物の屋上部に設けられており、エレベータの保守作業は主にこの機械室で行われている。
【０００３】
一方、エレベータを設置するスペースを最小のものとする目的で、巻上機と制御盤を設置するための機械室を不要とした機械室レスエレベータが提案されている。すなわち、巻上機と制御盤を昇降路上部や最下部に収納する方法が採用されてきている（例えば、特許文献１参照）。
【０００４】
【特許文献１】
特開２０００−３１８９４８号公報
【０００５】
【発明が解決しようとする課題】
しかしながら、このような構成の従来の機械室レスエレベータの巻上機保守方法においては、従来のエレベータにおいて機械室に設置されていた巻上機や制御盤を昇降路内に設置することとなるが、ピット深さやオーバーヘッド寸法を出来る限り小さなものとする為には、巻上機や制御盤を昇降路内の乗かごの上下方向の移動範囲外、つまり、乗かごを上下方向に投影した領域と昇降路内壁との間の空間に設置する必要がある。一方、エレベータの設置体積は極力小さくされることが望まれており、このようなことから、巻上機と制御盤とが昇降路内で近づいて設けられることがある。このようなエレベータにおいて、巻上機の保守作業時に制御盤が邪魔になって、必要なスペースを確保することができないという問題があった。
【０００６】
この発明は、上述のような課題を解決するためになされたもので、昇降路断面積を大きくすることなく、巻上機の保守作業時に必要なスペースを確保することができる機械室レスエレベータの巻上機保守方法を得ることを目的とする。
【０００７】
【課題を解決するための手段】
この発明に係る機械室レスエレベータの巻上機保守方法は、昇降路内に巻上機、及び制御盤が配置された機械室レスエレベータの巻上機保守方法であって、制御盤を、巻上機の保守作業スペースに干渉する通常位置と、作業スペースから外れた待避位置との間に移動可能に設け、エレベータの運転時は、制御盤を通常位置に固定し、巻上機の保守作業を行う際には、制御盤を待避位置に固定する。
【０００８】
【発明の実施の形態】
実施の形態１．
図１は機械室レスエレベータの昇降路内の機器設置可能な空間を示す昇降路１の横断面図である。図１において、矢印Ａは、乗場の方向を示している。昇降路１内には図示しない乗かごが昇降する。そのために、図中２点鎖線で示す乗かごの上下方向の移動範囲、つまり、乗かごを上下方向に投影した領域に、巻上機や制御盤を配置することができない。すなわち、巻上機や制御盤は、乗かごを上下方向に投影した領域と昇降路１の内壁との間の概略断面コの字型の空間（図中薄墨の部分）に設置する必要がある。また、昇降路１内には、乗かごの昇降方向に延びる乗かご用案内レール２やつり合い重り用案内レール３が配設されるので、巻上機や制御盤の設置可能な空間はさらに制限される。
【０００９】
図２は巻上機５の保守作業スペースと制御盤６とが干渉する様子を示す昇降路１の横断面図である。図２において、つり合い重り６は、つり合い重り用案内レール３に案内されて昇降路１内を昇降する。巻上機５は、扁平状の空間に設置可能とするために薄型のものが用いられている。そして本実施の形態において、巻上機５は昇降路１の最下部に配置されており、さらに詳細には、巻上機５は、つり合い重り用案内レール３の側方にて昇降路１奥の壁面１ａと平行に設置されている。一方、制御盤６も巻上機５は昇降路１の最下部に配置されており、巻上機５に近い側の側壁面１ｂに平行に設置されている。そして、制御盤６は、乗かごの縦枠等と干渉することを防ぐため、巻上機５に接近して設置されている。図２中太線斜線Ｂで示す部分は、巻上機５を保守作業する際に必要とする巻上機５前面の保守作業スペースであるが、制御盤６は、この保守作業スペースと干渉している。
【００１０】
図３は制御盤６を通常位置に固定した状態を示す正面図である。図４は制御盤６を待避位置に移動させた状態を示す正面図である。制御盤６は矩形細長形状をなし、扁平状の空間に設置可能とするために薄型に作製され、上下方向に延びて配置されている。昇降路固定部としての乗かご用案内レール２から水平方向一側に延びるように、第１の腕７と第２の腕８が平行に立設されている。第１の腕７と第２の腕８とは、上下方向に所定の間隔離れて設けられている。
【００１１】
制御盤６の上部は、上部支持軸としてのボルト１０にて支持されている。また、制御盤６の下部は、２個のボルト１１にて支持されている。制御盤６は、待避位置では、図４に示されるように所定の角度傾いて固定され、巻上機５の前部に所定の保守作業スペースを確保する。尚、図４中２点鎖線は、制御盤６の扉の開く範囲を示している。図５に制御盤６の扉６ｅ，６ｆの開いた様子を示す。制御盤６の扉は、上扉６ｅと下扉６ｆとに分割され、それぞれ蝶番で支持され別々に開放可能とされている。本発明の保守方法は、制御盤６を所定の角度傾けた待避位置に固定することにより、巻上機５の保守作業スペースを確保するものであるが、同時に制御盤６の扉６ｅ，６ｆを大きく開くようにし、作業性を向上させる。尚、上部支持軸は、一側に回動可能な構造であれば、ボルト１０に限られるものではない。
【００１２】
図６は制御盤６の上部が支持される様子を示す要部正面図である。図７は図６のＶＩＩ視断面図である。制御盤６上部の薄板部６ａに貫通穴６ｃが穿孔されている。また、乗かご用案内レール２から延びる第１の腕７には、所定の位置に雌ねじ穴７ａが螺刻されている。そして、ボルト１０が雌ねじ穴７ａに螺合して、ボルト１０の頭部と腕７との間に隙間Ｄを形成し、裏面側の螺合するナット１２にて締め付けられて立設されている。制御盤６の薄板部６ａは、貫通穴６ｃにボルト１０を貫通させて、隙間Ｄの内にて回動自在に支持されている。
【００１３】
図８は制御盤６下部の薄板部６ｂの両側部に設けられた２個の貫通穴６ｄを示す正面図である。図９は第２の腕８に設けられた通常位置固定用ねじ穴８ａと待避位置固定用ねじ穴８ｂを示す正面図である。図１０は制御盤６の下部を支持する様子を示す通常位置での要部正面図である。図１１は制御盤６の下部を支持する様子を示す待避位置での要部正面図である。図８に示されるように、制御盤６下部の薄板部６ｂの両側部に２個の貫通穴６ｄが穿孔されている。図に示されるように、乗かご用案内レール２から延びる第２の腕８には、通常位置の２個の貫通穴６ｄに対応する位置に、通常位置固定手段としての通常位置固定用ねじ穴（雌ねじ穴）８ａが２個螺刻され、また、制御盤６が待避位置に移動したときに、図８の右側の貫通穴６ｄが位置する場所に、待避位置固定手段としての待避位置固定用ねじ穴（雌ねじ穴）８ｂが１個螺刻されている。
【００１４】
制御盤６の下部は、図１０に示す通常位置にある場合、２個の貫通穴６ｄにそれぞれボルト１１を貫通させて腕８に締着されている。また、制御盤６を通常位置から待避位置へ移動させる場合には、まず２本のボルト１１を外して、図１１中矢印Ｃ示すように腕８の主面と平行な平面内で所定の角度だけ回動させて、図１１の右側の貫通穴６ｄを待避位置固定用ねじ穴８ｂに位置合わせしてボルト１１にて締着する。もう１本のボルト１１は、紛失することのないように図９の右側の通常位置固定用ねじ穴８ａにねじ込んでおく。尚、固定手段は、雌ねじとこれに螺合するボルトに限らず、他の係合手段でも良い。
【００１５】
そして、本実施の形態の機械室レスエレベータの巻上機保守方法においては、制御盤６を、巻上機５の保守作業スペースに干渉する通常位置と、この作業スペースから外れた待避位置との間に移動可能に設け、通常のエレベータの運転時は、制御盤６を通常位置に固定し、一方、巻上機５の保守作業を行う際には、制御盤６を待避位置に固定する。そのため、昇降路１の断面積を大きくすることなく、巻上機５の保守作業時に必要なスペースを確保することができる。
【００１６】
また、制御盤６の上部を支持部材に回動自在に取り付け、制御盤６の下部を支持部材に着脱可能に取り付け、制御盤６が所定の角度回動することにより、通常位置と待避位置との間を移動可能とするので、制御盤６の移動可能な構成を容易に実現することができる。
【００１７】
さらに、乗かご用案内レール２から延びる第１の腕７に立設するボルト１０に、制御盤６の上部を回動自在に取り付け、また、乗かご用案内レール２から延びる第２の腕８に、制御盤６の下部が通常位置で固定される通常位置固定手段と待避位置で固定される待避位置固定手段を設けておき、いずれかの固定手段によって、通常位置或いは待避位置に固定する。そのため、制御盤６を通常位置或いは待避位置に確実に固定することができ、信頼性が向上する。
【００１８】
さらにまた、通常位置固定手段及び待避位置固定手段は、第２の腕８に形成された通常位置固定用ねじ穴８ａ及び待避位置固定用ねじ穴８ｂとこれらに螺合するボルト１１であるので、構造が非常に簡単になりコストダウンを図ることができる。
【００１９】
【発明の効果】
この発明に係る機械室レスエレベータの巻上機保守方法は、昇降路内に巻上機、及び制御盤が配置された機械室レスエレベータの巻上機保守方法であって、制御盤を、巻上機の保守作業スペースに干渉する通常位置と、作業スペースから外れた待避位置との間に移動可能に設け、エレベータの運転時は、制御盤を通常位置に固定し、巻上機の保守作業を行う際には、制御盤を待避位置に固定するので、昇降路断面積を大きくすることなく、巻上機の保守作業時に必要なスペースを確保することができる。

[Problems to be solved by the invention]
However, in the conventional hoisting machine maintenance method for a machine room-less elevator having such a configuration, a hoisting machine or a control panel installed in a machine room in a conventional elevator is installed in a hoistway. In order to make the pit depth and overhead dimensions as small as possible, the hoist and control panel must be outside the vertical movement range of the car in the hoistway, that is, the area where the car is projected vertically. It must be installed in the space between the hoistway inner wall. On the other hand, it is desired that the installation volume of the elevator is as small as possible. For this reason, the hoist and the control panel may be provided close to each other in the hoistway. In such an elevator, there has been a problem that a control panel becomes an obstacle during maintenance work of the hoisting machine, and a necessary space cannot be secured.
[0006]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and is intended to provide a machine room-less elevator that can secure a space required for maintenance work of a hoist without increasing the cross-sectional area of a hoistway.

The control panel 6 has a rectangular elongated shape, is made thin in order to be able to be installed in a flat space, and is arranged to extend in the vertical direction. A first arm 7 and a second arm 8 are erected in parallel so as to extend to one side in the horizontal direction from the car guide rail 2 as a hoistway fixing portion. The first arm 7 and the second arm 8 are vertically separated by a predetermined distance.
[0011]
The upper portion of the control panel 6 is supported by bolts 10 serving as upper support shafts. The lower part of the control panel 6 is supported by two bolts 11. In the retracted position, the control panel 6 is fixed at a predetermined angle as shown in FIG. 4 to secure a predetermined maintenance work space at the front of the hoisting machine 5. Note that the two-dot chain line in FIG. 4 indicates the range in which the door of the control panel 6 opens. FIG. 5 shows a state where the doors 6e and 6f of the control panel 6 are opened. The door of the control panel 6 is divided into an upper door 6e and a lower door 6f, each of which is supported by a hinge and can be opened separately.

FIG. 9 is a front view showing a screw hole 8a for fixing a normal position and a screw hole 8b for fixing a retracted position provided in the second arm 8. FIG. FIG. 10 is a main part front view at a normal position showing a state in which the lower part of the control panel 6 is supported. FIG. 11 is a front view of a main part at a retracted position showing a state in which the lower part of the control panel 6 is supported. As shown in FIG. 8, two through holes 6d are formed in both sides of the thin plate portion 6b below the control panel 6. As shown in the figure, the second arm 8 extending from the car guide rail 2 has a normal position fixing screw hole as a normal position fixing means at a position corresponding to the two through holes 6d at the normal position. (Two female screw holes) 8a are threaded, and when the control panel 6 is moved to the retreat position, the retreat position fixing means as the retreat position fixing means is provided at the position where the through hole 6d on the right side of FIG. 8 is located. One screw hole (female screw hole) 8b is threaded.
[0014]
When the lower portion of the control panel 6 is at the normal position shown in FIG. 10, the bolt 11 is inserted through each of the two through holes 6d and fastened to the arm 8. When the control panel 6 is moved from the normal position to the retracted position, first, the two bolts 11 are removed, and a predetermined angle is set in a plane parallel to the main surface of the arm 8 as shown by an arrow C in FIG. By rotating the through hole only, the through hole 6d on the right side in FIG. The other bolt 11 is screwed into the normal position fixing screw hole 8a on the right side in FIG. 9 so as not to be lost. The fixing means is not limited to the female screw and the bolt screwed thereto, but may be another engaging means.
[0015]
In the maintenance method for the hoisting machine of the machine room-less elevator according to the present embodiment, the control panel 6 is moved between the normal position where it interferes with the maintenance work space of the hoisting machine 5 and the retracted position deviating from this work space. The control panel 6 is fixed at a normal position during normal elevator operation, while the control panel 6 is fixed at a retracted position when performing maintenance work on the hoisting machine 5. Therefore, the space required for the maintenance work of the hoisting machine 5 can be secured without increasing the sectional area of the hoistway 1.
