Description

【0001】
【発明の属する技術分野】
本発明は、ロープトラクション式エレベータに係り、特に機械室を有しない省スペース型のエレベータに関するものである。
【0002】
【従来の技術】
従来の機械室なしエレベータの例を図3及び図4により説明する。図3は全体概略図、図4は昇降路の横断面図である。
図において、4,5はかご1の下部に設置されたそらせシーブ、9はカウンターウエイト2を吊り下げている吊りシーブ、6は昇降路15の頂上部に設置され駆動シーブ7を駆動する駆動装置、8は制御装置である。3は主ロープであり、一端は昇降路上部の固定部材13に固定され、吊りシーブ9,駆動シーブ7,そらせシーブ5,4を経由して昇降路上部の固定部材14に固定されている。
【0003】
10はかご1のガイドレール、11はカウンターウエイト2のガイドレール、17は乗場出入口、18はかご1の出入口である。
上記駆動装置6〜制御装置8は、かご1が昇降に必要な空間又はこの空間の上方向への延長部と、昇降路15の壁との間の空間に設置されている。
【0004】
【発明が解決しようとする課題】
上記従来のエレベータ装置では、駆動装置6〜制御装置8は、かご1が昇降に必要な空間又はこの空間の上方向への延長部と、昇降路15の壁との間の空間という狭い空間に設置されているため、駆動装置6は薄型の構造にする必要がある。しかしながら、例えば駆動装置6を円盤状の回転子を有するディスクモータを使ったギヤレスマシンにすると、モータの効率が悪くなるという問題がある。
【0005】
また、ディスクモータの代わりに通常のタイプのモータ、即ち回転子と固定子とのギャップが回転軸と平行になっている円筒型のモータを使用した場合には、薄型のため回転子と固定子との対向面積が小さくなって所定の出力が出せなくなる可能性がある。
【0006】
【課題を解決するための手段】
本発明は、駆動装置や駆動シーブを、従来のようにかごが昇降に必要な空間又はこの空間の上方向への延長部と、昇降路の壁との間の空間、という狭い空間に設置するのではなく、より広い空間に設置することにより、駆動装置やモータの制約条件を緩和するものである。
本発明では、住宅用エレベータに使用されるトランク付きエレベータのトランク上方の空間に着目し、従来利用されていなかったこの空間を駆動装置や駆動シーブの設置場所として利用したものである。
【0007】
【発明の実施の形態】
本発明の実施の形態を図により説明する。図1は全体概略図、図2は昇降路の横断面図であり、図3,図4と同一符号は同一のものを示している。
【0008】
図において、20はトランク21を備えたかご、30はマシンビームであり、かご20が昇降路の最上位置にあるときに、かご20及びトランク21と干渉しない位置に設けられている。31はマシンビーム30に固定された駆動装置である。本実施形態においては、マシンビーム30、駆動装置31及び駆動シーブ7の大部分は、水平投影面上においてトランク21と重なって配置され、また一部は上下方向において昇降路の最上位置にあるときのかご20と重なっている。
【0009】
主ロープ3は、一端は昇降路上部の固定部材13に固定され、吊りシーブ9、昇降路上部の転換シーブ42、駆動シーブ7、昇降路下部の転換シーブ41、昇降路上部の転換シーブ40、かご20のそらせシーブ5,4を経由して、昇降路上部の固定部材14に固定されている。
【0010】
本実施形態によれば、駆動装置31や駆動シーブ7を、トランク21の上方空間という広いスペースに設置できるため、従来技術に比べ駆動装置やモータの制約条件が緩和される。したがって、駆動装置はギヤレスでもギヤードでもよく、モータもディスク型でも円筒型でもよい。そしてより効率の良いものや安価な汎用品の使用も可能になってくるため、安価で実用性の高いエレベータ装置を実現できる。
【0011】
上記実施形態においては、かご20の下部にそらせシーブ4、5を備えたいわゆるアンダースラング式を例にとって説明しているが、これに限ることはない。例えば、L字型の枠にかご室を載置した、いわゆるサイドフォーク式等でもよく、要するにトランク付きのかごを備えたエレベータであれば本発明を適用できる。
【0012】
【発明の効果】
以上説明したように、本発明によれば、トランク付きエレベータにおいて、駆動装置などの設置スペースを広くとることができるため、省スペース型のエレベータにおいても、安価で実用性の高いエレベータ装置を実現することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a rope traction type elevator, and more particularly to a space-saving type elevator having no machine room.
[0002]
[Prior art]
An example of a conventional elevator without a machine room will be described with reference to FIGS. FIG. 3 is an overall schematic view, and FIG. 4 is a transverse sectional view of the hoistway.
In the figure, 4 and 5 are deflecting sheaves installed at the bottom of the car 1, 9 is a hanging sheave that suspends the counterweight 2, and 6 is a driving device that is installed at the top of the hoistway 15 and drives the driving sheave 7. , 8 is a control device. Reference numeral 3 denotes a main rope, one end of which is fixed to a fixing member 13 at the upper part of the hoistway, and is fixed to a fixing member 14 at the upper part of the hoistway through the suspension sheave 9, the drive sheave 7, and the deflecting sheaves 5 and 4.
[0003]
10 is a guide rail of the car 1, 11 is a guide rail of the counterweight 2, 17 is a landing entrance, and 18 is an entrance of the car 1.
The driving device 6 to the control device 8 are installed in a space between the space required for the car 1 to move up and down or an upward extension of this space and the wall of the hoistway 15.
[0004]
[Problems to be solved by the invention]
In the above-described conventional elevator apparatus, the driving device 6 to the control device 8 are arranged in a narrow space called a space between the space required for the car 1 to move up and down or an upward extension of this space and the wall of the hoistway 15. Since it is installed, the driving device 6 needs to have a thin structure. However, for example, if the drive device 6 is a gearless machine using a disk motor having a disk-shaped rotor, there is a problem that the efficiency of the motor is deteriorated.
[0005]
In addition, when a normal type motor, that is, a cylindrical motor in which the gap between the rotor and the stator is parallel to the rotation axis, is used instead of the disk motor, the rotor and the stator are thin. There is a possibility that a predetermined output cannot be output due to a decrease in the facing area.
[0006]
[Means for Solving the Problems]
In the present invention, the drive device and the drive sheave are installed in a narrow space such as a space necessary for the car to move up and down, or a space between the upward extension of this space and the wall of the hoistway as in the prior art. Rather than restricting the drive device and the motor, the installation conditions are relaxed by installing the device in a wider space.
In the present invention, attention is paid to the space above the trunk of an elevator with a trunk used for a residential elevator, and this space, which has not been conventionally used, is used as a place for installing a drive device and a drive sheave.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. 1 is an overall schematic view, and FIG. 2 is a transverse sectional view of a hoistway. The same reference numerals as those in FIGS. 3 and 4 denote the same components.
[0008]
In the figure, reference numeral 20 denotes a car provided with a trunk 21, and 30 denotes a machine beam, which is provided at a position where it does not interfere with the car 20 and the trunk 21 when the car 20 is at the uppermost position of the hoistway. Reference numeral 31 denotes a driving device fixed to the machine beam 30. In the present embodiment, most of the machine beam 30, the drive device 31, and the drive sheave 7 are arranged so as to overlap the trunk 21 on the horizontal projection plane, and a part thereof is at the uppermost position of the hoistway in the vertical direction. It overlaps with the basket 20.
[0009]
One end of the main rope 3 is fixed to the fixing member 13 at the upper part of the hoistway, the suspension sheave 9, the conversion sheave 42 at the upper part of the hoistway, the drive sheave 7, the conversion sheave 41 at the lower part of the hoistway, the conversion sheave 40 at the upper part of the hoistway, It is fixed to the fixing member 14 at the upper part of the hoistway through the deflecting sheaves 5 and 4 of the car 20.
[0010]
According to the present embodiment, the drive device 31 and the drive sheave 7 can be installed in a wide space above the trunk 21, so that the constraint conditions of the drive device and the motor are relaxed as compared with the prior art. Therefore, the drive device may be gearless or geared, and the motor may be a disk type or a cylindrical type. Since more efficient and inexpensive general-purpose products can be used, an inexpensive and highly practical elevator device can be realized.
[0011]
In the above embodiment, a so-called underslang type in which the sheaves 4 and 5 are provided at the lower part of the car 20 has been described as an example, but the present invention is not limited to this. For example, a so-called side fork type in which a car room is placed on an L-shaped frame may be used. In short, the present invention can be applied to any elevator provided with a car with a trunk.
[0012]
【The invention's effect】
As described above, according to the present invention, since an installation space for a drive device or the like can be widened in an elevator with a trunk, an inexpensive and highly practical elevator device is realized even in a space-saving elevator. be able to.
