Description

技術分野
この発明は、巻上機、そらせ車が昇降路頂部に配置されている機械室レスエレベータに関するものである。
背景技術
図１０〜１３は従来の１：１ローピングの機械室レスエレベータを示すもので、図中、１は昇降路、２は昇降路頂部、３はかご、４はおもり、５はおもり４を懸架するそらせ車、６は昇降路頂部２に設置され、シーブ７とモータ部８により構成された巻上機、９はかご３の昇降をガイドする一対のかご側レール、１０はおもり４の昇降をガイドする一対のおもり側ガイドレール、１１はかご側レール９、おもり側レール１０のそれぞれの先端部に取り付けられた支持金、１２は支持金１１に弾性体１３を介して固定され巻上機６およびそらせ車５を保持した機械台、１４は巻上機６のシーブ７およびそらせ車５に巻き掛けられ、一端部がおもり４の上部の綱止め５０に固定され、他端部がかご３の上部の綱止め５１に固定された主索である。
おもり４の上部の綱止め５０に端部が固定された主索１４は、綱止め５０から昇降路１に沿って上昇した後、そらせ車５の上側を巻き掛けされている。その後、主索１４は巻上機６のシーブ７へと延びている。
次に、主索１４はシーブ７に巻き掛けされている。この際、そらせ車５から延びた主索１４は、シーブ７の下部から巻き始め、図１０において反時計方向にほぼ全周巻き掛けされた後、昇降路１を下降してかご３へと延び、最後にはかご３の綱止め５１に固定されている。
上記構成の機械室レスエレベータでは、主索１４をシーブ７に巻き掛けると、主索１４はそらせ車５からシーブ７へと延びた箇所と、シーブ７からかご３へと延びた箇所とが交差することになるが、主索１４が互いに干渉しないようになっている。
即ち、巻上機６はシーブ７がそらせ車５に対して水平に１．５度、垂直方向に２．５度以内で偏芯して設置されている。図１２および図１３は図１０におけるシーブ７とそらせ車５との位置関係を示した図で、図１２はその平面図、図１３はその側面図である。なお、図１２および図１３においてＸ軸、Ｙ軸およびＺ軸は直交座標系を示しており、Ｘ軸はそらせ車５の回転軸方向、Ｙ軸は水平方向、Ｚ軸は垂直方向を示している。
上記構成の機械室レスエレベータでは、巻上機６のモータ部８が駆動すると、シーブ７が回転し、トラクションにより主索１４が移動する。主索１４の移動に伴い、かご３とおもり４はそれぞれ上下逆方向に昇降動作する。
従来の機械室レスエレベーターは、以上のように構成されており、巻上機６をそらせ車５に対し水平、垂直双方に対し傾斜させているので、主索１４としてワイヤロープを使用した場合は、シーブ７およびそらせ車５のそれぞれのロープ溝のコーナ部での擦れは避けられず、また主索１４としてベルトを用いたときには、ベルトに対して偏荷重となりベルトに悪影響を与えるという言う問題点があった。
発明の開示
この発明は、上記のような問題点を解消するもので、複数の車の主索を掛ける溝が一直線になるように車を配置して、主索をこれらの車に巻き掛けることによりトラクションの確保と主索の長寿命化を図り、併せて昇降路垂直方向の設置スペースを縮小できる機械室レスエレベータを提供することを目的とする。
この発明による機械室レスエレベータでは、シーブ、かご側そらせ車およびおもり側そらせ車は、昇降路に沿って視たときに直線上に配置されているとともに、上記シーブ、上記かご側そらせ車および上記おもり側そらせ車のそれぞれの軸線は平行であり、主索は、おもりから上記昇降路に沿って上昇した後、上記おもり側そらせ車の上側を巻き掛けされ、その後上記シーブ、上記かご側そらせ車に巻き掛けされ、上記昇降路を下降してかごに至るようになっている。
また、この発明による機械室レスエレベータでは、シーブ、おもり側そらせ車および遊び車は、昇降路に沿って視たときに直線上に配置されているとともに、上記シーブ、上記おもり側そらせ車および上記遊び車のそれぞれの軸線は平行であり、主索は、おもりから上記昇降路に沿って上昇した後、上記おもり側そらせ車、上記遊び車および上記シーブに巻き掛けされ、その後上記昇降路を下降してかごに至るようになっている。
また、この発明による機械室レスエレベータでは、シーブおよびかご側そらせ車は、昇降路に沿って視たときに直線上に配置されているとともに、遊び車は、上記シーブの下側に重なって配置され、また上記遊び車、上記シーブおよび上記かご側そらせ車のそれぞれの軸線は平行であり、主索は、おもりから上記昇降路に沿って上昇した後、上記遊び車、上記シーブおよび上記かご側そらせ車に巻き掛けされ、その後上記昇降路を下降してかごに至るようになっている。
また、この発明による機械室レスエレベータでは、シーブ、遊び車およびかご側そらせ車は、昇降路に沿って視たときに直線上に配置されているとともに、上記シーブ、上記遊び車および上記かご側そらせ車のそれぞれの軸線は平行であり、主索は、おもりから上記昇降路に沿って上昇した後、上記シーブの上側、上記遊び車の下側および上記かご側そらせ車の上側に巻き掛けされ、その後上記昇降路を下降してかごに至るようになっている。
発明を実施するための最良の形態
以下、この発明の好適な実施の形態について図面を参照して説明するが、各実施の形態において同一、同等部材、または部位については、同一符号を付して説明する。
実施の形態１．
図１はこの発明の実施の形態１による機械室レスエレベータの概略斜視図、図２は図１の昇降路頂部の平面図、図３は図２のＡ−Ａ線矢視断面図である。
図において、１は昇降路、２は昇降路頂部、３はかご、４はおもり、５はおもり４を懸架するそらせ車、６は昇降路頂部２に設置され、シーブ７とモータ部８により構成された巻上機、９はかご３の昇降をガイドする一対のかご側レール、１０はおもり４の昇降をガイドする一対のおもり側ガイドレール、１１はかご側レール９、おもり側レール１０のそれぞれの先端部に取り付けられた支持金、１３は支持金１１に固定され巻上機６の駆動振動を建物に伝幡するのを防止した弾性体、１２は支持金１１に弾性体１３を介して固定された機械台、１４は一端部がおもり４の上部の綱止め５０に固定され、他端部がかご３の上部の綱止め５１に固定された主索である。１５は機械台１２に支持されたかご側そらせ車で、シーブ７とおもり側そらせ車５との間に夫々の軸線が水平、平行で一列に配置され、主索１４を掛けるシーブ７、かご側そらせ車１５、おもり側そらせ車５のそれぞれの溝は一直線上に配置されている。
１６は機械台１２に固定されエレベータを制御する制御盤、１７は機械台１２に固定されエレベータの速度を検知し非常停止させる調速機、１８は機械台１２に端部が回動可能に設けられているとともに伸縮自在の保守用タラップである。制御盤１６、調速機機１７およびタラップ１８は巻上機６の高さよりも低い位置に配置されている。なお、図１においては、調速機１７およびタラップ１８は省略されている。
おもり４の上部の綱止め５０に端部が固定された主索１４は、綱止め５０から昇降路１に沿って上昇した後、そらせ車５の上側を巻き掛けされている。その後、主索１４は巻上機６のシーブ７へと延びている。
その後、主索１４はシーブ７に巻き掛けされている。この際、そらせ車５から延びた主索１４は、シーブ７の上部から巻き始め、図１において反時計方向にほぼ半周巻き掛けされた後、引き続きかご側そらせ車１５の上部をほぼ半周巻き掛けされた後、昇降路１を下降してかご３へと延び、最後にかご３の綱止め５１に固定されている。
この機械室レスエレベータによれば、そらせ車５、かご側そらせ車１５およびシーブ７は直線上に配置されているので、主索１４はそれぞれの溝に無理に係合させるようなことはなく、主索１４の長寿命化とエレベータ巻上げトラクションの確保が可能となる。
また、機械台１２は、巻上機６の高さ方向の領域内に収まっており、また制御盤１６、調速機１７および保守用タラップ１８は巻上機６の高さよりも低い位置に配置されているので、昇行路頂部２のスペースは小さくてよい。
また、この機械室レスエレベータの場合、主索１４のシーブ７に対する巻付角は、最小トラクションを確保するのに必要な最小巻付角である１２０°以上で最大２７０°程度まで可能となり、大きなトラクション能力を要する場合に好都合である。
なお、主索１４してワイヤロープに代えて、多数列に並べた細いワイヤロープが内在した平ベルトを採用するとシーブ径が小さくなり、エレベータのアンバランストルクが減り、巻上機６、シーブ７、そらせ車５，１５の径が小さくなり、昇降路頂部のスペースの縮小を図ることができる。
また、かご側そらせ車１５、シーブ７、おもり側そらせ車５は夫々の軸線が水平、平行であるが、必ずしも水平である必要性はない。
実施の形態２．
図４はこの発明の実施の形態２の機械室レスエレベータの斜視図、図５は図４の昇降路頂部の平面図である。
この実施の形態では、巻上機７のシーブ７、遊び車１９、おもり側そらせ車５が、昇降路１に沿って視たときに直線上に機械台１２に固定されている。シーブ７、遊び車１９、おもり側そらせ車５のそれぞれの軸線は水平、平行である。
おもり４の上部の綱止め５０に端部が固定された主索１４は、綱止め５０から昇降路１に沿って上昇した後、そらせ車５の上側を巻き掛けされている。その後、主索１４は遊び車１９の下側を半周巻き掛けされた後、シーブ７の上側を半周巻き掛けされている。引き続き、昇降路１を下降してかご３へと延び、最後にはかご３の綱止め５１に固定されている。
この実施の形態によれば、機械台１２に固定される遊び車１９の位置でシーブ７に対する主索１４の巻付角は調整可能で、所定のトラクションを確保できる。
また、シーブ７、遊び車１９、おもり側そらせ車５が直線上に配置され、それぞれの軸線は水平、平行であるので、主索１４の長寿命化を図ることができる。
また、遊び車１９の高さは、巻上機６の高さよりも低いので、実施の形態１と同様、昇行路頂部２のスペースは小さくてよい。
なお、シーブ７、遊び車１９、おもり側そらせ車５のそれぞれの軸線は水平でなくてもよい。
実施の形態３．
図６はこの発明の実施の形態３の機械室レスエレベータの斜視図、図７は図６の昇降路頂部の平面図である。
この実施の形態では、巻上機６が昇降路頂部２のおもり４の上方に機械台１２に固定されて配置されている。巻上機６の下側には遊び車１９が重なるようにして設けられている。また、シーブ７、かご側そらせ車１５は、昇降路１に沿って視たときに直線上に機械台１２に固定されており、またそれぞれの軸線は平行である。
おもり４の上部の綱止め５０に端部が固定された主索１４は、綱止め５０から昇降路１に沿って上昇した後、遊び車１９に片側を巻き掛けされている。その後、主索１４はシーブ７の片側を約半周巻き掛けされた後、かご側そらせ車１５の約１／４周巻き掛けされている。引き続き、主索１４は昇降路１を下降してかご３へと延び、最後にはかご３の綱止め５１に固定されている。
この実施の形態によれば、機械台１２に固定される遊び車１９の位置でシーブ７に対する主索１４の巻付角は調整可能で、所定のトラクションを確保できる。
また、遊び車１９、シーブ７およびかご側そらせ車１５が直線上に配置され、それぞれの軸線は平行であるので、主索１４の長寿命化を図ることができる。
また、図示してないが、遊び車１９をシーブ７とかご側そらせ車１５との間に配置し、主索１４を、おもり４から昇降路１に沿って上昇した後、シーブ７の上側を巻き掛けし、その後遊び車１９の下側を巻き掛けし、引き続きかご側そらせ車１５の上側を約半周巻き掛けし、最後に昇降路１を下降してかご３に至るようにしてもよい。このとき、シーブ７、遊び車１９およびかご側そらせ車１５は、昇降路１に沿って視たときに直線上に配置されているとともに、シーブ７、遊び車１９およびかご側そらせ車１５のそれぞれの軸線は平行であるので、主索１４の長寿命化を図ることができる。
実施の形態４．
図８は、実施の形態１ないし実施の形態３の主索１４としてベルトを用いたときのベルトの端部に固定された固定部材の斜視図、図９は図８のＢ−Ｂ線矢視断面図である。
図において、２０は水平方向に突出した複数の突部２０ａを有する固定具、２１は固定具２０の突部２０ａに沿うように形成された凹部２１ａを有する押付金具で、ボルト２２で固定具２０と押付金具２１との間に主索１４を挟み付けるようになっている。押付金具２１には折り返された主索１４の端部を固定する金具２３を有しており、この金具２３はボルト２４で押付金具２１に固定されている。２５は吊ボルトで固定具２０とは、ピン２６により結合されている。
この実施の形態によれば、一般的に採用されているワイヤロープのシャックル同様、主索１４であるベルトに対しても十分な保持力が期待でき、コンバクトに構成できると共に据付現場での施工も容易でなる。
なお、上記各実施の形態では詳細を説明しないが、かご或いはおもりサイズの変化に応じて、実施の形態１ないし３を組み合わせた機械室レスエレベータであってもよい。
また、各実施の形態では機械台１２はかご側ガイドレール９およびおもり側ガイドレール１０に固定されているが、昇降路の壁部である壁面または壁面に沿って延びた壁部である柱に機械台を固定するようにしてもよい。

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be described below with reference to the drawings. In each embodiment, the same reference numerals are given to the same, equivalent members or parts. explain.
Embodiment 1 FIG.
1 is a schematic perspective view of a machine room-less elevator according to Embodiment 1 of the present invention, FIG. 2 is a plan view of the top of a hoistway in FIG. 1, and FIG. 3 is a cross-sectional view taken along line AA in FIG.
In the figure, 1 is a hoistway, 2 is a hoistway top, 3 is a car, 4 is a weight, 5 is a baffle for suspending a weight 4, 6 is installed on the hoistway top 2, and comprises a sheave 7 and a motor unit 8. 9 is a pair of car-side rails for guiding the lifting and lowering of the car 3, 10 is a pair of weight-side guide rails for guiding the lifting and lowering of the weight 4, and 11 is a car-side rail 9 and a weight-side rail 10, respectively. The support metal 13 attached to the tip of the elastic member 13 is fixed to the support metal 11 to prevent the drive vibration of the hoist 6 from being transmitted to the building, and 12 is connected to the support metal 11 via the elastic material 13. The fixed machine base 14 is a main rope having one end fixed to the rope clamp 50 at the upper part of the weight 4 and the other end fixed to the rope clamp 51 at the upper part of the car 3. Reference numeral 15 denotes a car side deflector supported by the machine base 12, and the sheave 7 and the car side on which the axes are horizontally and parallelly arranged in a line between the sheave 7 and the weight side deflector 5. The grooves of the deflector 15 and the weight-side deflector 5 are arranged in a straight line.
16 is a control panel that is fixed to the machine base 12 and controls the elevator, 17 is a speed governor that is fixed to the machine base 12 and detects the speed of the elevator and makes an emergency stop, and 18 is provided on the machine base 12 so that its end can be rotated. This is a maintenance trap that is retractable and stretchable. The control panel 16, the governor 17, and the trap 18 are disposed at a position lower than the height of the hoist 6. In FIG. 1, the governor 17 and the trap 18 are omitted.
The main rope 14, the end of which is fixed to the clasp 50 on the upper part of the weight 4, is lifted along the hoistway 1 from the clasp 50, and is then wound around the upper side of the deflector 5. Thereafter, the main rope 14 extends to the sheave 7 of the hoist 6.
Thereafter, the main rope 14 is wound around the sheave 7. At this time, the main rope 14 extending from the deflector 5 starts to wind from the upper part of the sheave 7 and is wound approximately half a turn counterclockwise in FIG. After that, the hoistway 1 is lowered and extended to the car 3, and finally fixed to the rope clamp 51 of the car 3.
According to this machine room-less elevator, since the deflecting wheel 5, the car-side deflecting wheel 15 and the sheave 7 are arranged in a straight line, the main rope 14 is not forced to be engaged with each groove, It is possible to extend the life of the main rope 14 and secure the elevator hoisting traction.
Further, the machine base 12 is accommodated in a region in the height direction of the hoisting machine 6, and the control panel 16, the speed governor 17 and the maintenance trap 18 are arranged at a position lower than the height of the hoisting machine 6. Therefore, the space of the ascending road top 2 may be small.
Further, in the case of this machine room-less elevator, the winding angle of the main rope 14 with respect to the sheave 7 can be 120 ° or more, which is the minimum winding angle necessary for securing the minimum traction, and can be up to about 270 °. This is convenient when traction capability is required.
If a flat belt having thin wire ropes arranged in multiple rows is used instead of the wire rope as the main rope 14, the sheave diameter is reduced, the unbalance torque of the elevator is reduced, and the hoisting machine 6 and the sheave 7 The diameters of the deflecting wheels 5 and 15 are reduced, and the space at the top of the hoistway can be reduced.
In addition, the car-side deflector 15, the sheave 7, and the weight-side deflector 5 have axes that are horizontal and parallel, but are not necessarily horizontal.
Embodiment 2. FIG.
4 is a perspective view of a machine room-less elevator according to Embodiment 2 of the present invention, and FIG. 5 is a plan view of the hoistway top portion of FIG.
In this embodiment, the sheave 7, the play wheel 19, and the weight side deflector 5 of the hoisting machine 7 are fixed to the machine base 12 on a straight line when viewed along the hoistway 1. The axes of the sheave 7, the play wheel 19, and the weight side deflector 5 are horizontal and parallel.
The main rope 14, the end of which is fixed to the clasp 50 on the upper part of the weight 4, is lifted along the hoistway 1 from the clasp 50, and is then wound around the upper side of the deflector 5. Thereafter, the main rope 14 is wound around the lower side of the play wheel 19 by a half turn and then wound around the upper side of the sheave 7 by a half turn. Subsequently, the hoistway 1 is lowered and extended to the car 3, and finally is fixed to the rope clamp 51 of the car 3.
According to this embodiment, the winding angle of the main rope 14 with respect to the sheave 7 can be adjusted at the position of the play wheel 19 fixed to the machine base 12, and a predetermined traction can be secured.
Moreover, since the sheave 7, the play wheel 19, and the weight side deflector 5 are arranged on a straight line and the respective axes are horizontal and parallel, the life of the main rope 14 can be extended.
Moreover, since the height of the playwheel 19 is lower than the height of the hoisting machine 6, the space of the ascending path top portion 2 may be small as in the first embodiment.
Note that the axes of the sheave 7, the play wheel 19, and the weight side deflector 5 need not be horizontal.

Further, the sheave 7 and the car side deflector 15 are fixed to the machine base 12 in a straight line when viewed along the hoistway 1, and their axes are parallel.
The main rope 14, the end of which is fixed to the pawl 50 at the upper part of the weight 4, rises from the pawl 50 along the hoistway 1, and is then wound around one side by the play wheel 19. Thereafter, the main rope 14 is wound around one half of the sheave 7 by about a half turn and then wound around a quarter turn of the car side deflecting wheel 15.
