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、従来のものと同一、相当部材、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のエレベータの構成図である。
このエレベータは、昇降路内を昇降するかご１と、昇降路内をかご１に連動して昇降する釣合重り２０と、この釣合重り２０に搭載された２台の巻上機２２ａ，２２ｂと、巻上機２２ａ、２２ｂに搭載されているとともに巻上機２２ａ、２２ｂの駆動を制御する制御装置１１と、一端部がかご１に接続され、他端部が、吊り車２３、返し車２４を通じて制御装置１１に接続されたかご用ロープ２１と、上端部が昇降路の天井にテンションコントローラ２６を介して接続されているとともに、下端部が昇降路の床面に接続され、また中間部が巻上機２２ａ，２２ｂにそれぞれ巻回された巻上機用ロープ２７ａ，２７ｂを備えている。
巻上機２２ａ，２２ｂは同一の仕様である。また、釣合重り２０、巻上機２２ａ，２２ｂおよび制御装置１１は、エレベータの据え付け前、即ち製造工場の出荷時に既に一体であり、重り本体２５を構成している。
また、巻上機２２ａ，２２ｂは、昇降路の延長線上に沿って視たときに、釣合重り２２の外形内に収まっている。
また、巻上機用ロープ２７ａ，２７ｂは、樹脂製ロープ、または樹脂が被覆されたロープで、可撓性を有しており、巻上機２２ａ，２２ｂに対して３６０°の巻回が可能であるとともに、テンションコントローラ２６により巻上機用ロープ２７ａ，２７ｂの経年的延び、振動等に対しても常に一定の張力が得られるようになっている。
上記エレベータでは、例えば図１において巻上機２２ａ，２２ｂが反時計方向に同期駆動したときには、巻上機用ロープ２７ａ，２７ｂが巻回された巻上機２２ａ，２２ｂを含む重り本体２５は、上昇するが、その重り本体２５に連動してかご１は降下する。
また、図１において巻上機２２ａ，２２ｂが時計方向に回転したときには、巻上機用ロープ２７ａ，２７ｂが巻回された巻上機２２ａ，２２ｂを含む重り本体２５は、降下するが、その重り本体２５に連動してかご１は上昇する。
上記のように構成されたエレベータでは、釣合重り２０には同一の２台の巻上機２２ａ，２２ｂが搭載されており、かご１の容量、速度に対する専用仕様の巻上機ではなく、２台の同期駆動する巻上機２２ａ，２２ｂで対処している。このような構成を採用することで、かごの容量、速度に対する専用仕様の巻上機を準備する必要性はない。
また、巻上機２２ａ，２２ｂは、それぞれ同一（形状、寸法、出力）であるので、据え付け作業および部品管理が簡単であり、またメンテナンスも容易である。
また、巻上機用ロープ２７ａ，２７ｂおよびかご用ロープ２１は別個であり、それぞれの使用状況に応じた最適なロープを選定することができるとともに、それだけロープ２７ａ，２７ｂ，かご用ロープ２１に対する負荷が軽減されて長寿命化が図れ、かつロープ全体を一律に交換するようなことが無く、要交換のロープのみを交換すればよい。
また、天井には巻上機用ロープ２７ａ，２７ｂを張設するテンションコントローラ２６が固定され、このテンションコントローラ２６により巻上機用ロープ２７ａ，２７ｂの張力が常に一定になるように調整されているので、巻上機２２ａ，２２ｂの駆動中に、巻上機用ロープ２７ａ，２７ｂが巻上機２２ａ，２２ｂからその軸線方向にずれるようなことは防止され、巻上機２２ａ，２２ｂの駆動力は、重り本体２５およびかご１の昇降力として確実に伝達される。
また、巻上機用ロープ２７ａ，２７ｂは可撓性のロープであるので、巻上機用ロープ２７ａ，２７ｂは曲率半径が小さい巻上機２２ａ，２２ｂに簡単に巻き掛けすることができる。
また、巻上機２２ａ，２２ｂは、昇降路の延長線上に沿って視たときに、釣合重り２０の外形内に収まる外形寸法であるので、巻上機２２ａ，２２ｂのために平面面積が増大するようなことは無い。
また、据え付け前に、予め釣合重り２０、巻上機２２ａ，２２ｂおよび制御装置１１は一体化されているので、現場での釣合重り２０、巻上機２２ａ，２２ｂおよび制御装置１１の据え付け時間が短縮化される。なお、据え付け前に、例えば予め釣合重り２０および巻上機２２ａ，２２ｂを一体化してもよいし、また巻上機２２ａ，２２ｂおよび制御装置１１を一体化してもよい。
なお、上記の実施の形態では、２台の巻上機２２ａ，２２ｂが釣合重り２０に搭載され、かつかご用ロープ２１、巻上機用ロープ２７ａ，２７ｂを備えたエレベータについて説明したが、一本のロープによりかごおよび釣合重りが吊されたエレベータにおいて、釣合重りに複数台の巻上機を搭載するものでもよい。
また、一台の巻上機が釣合重りに搭載されたエレベータにおいて、かご用ロープによりかごが吊され、巻上機用ロープによりその巻上機が吊されるようにしてもよい。
また、巻上機については、その台数については、３台以上であってもよい。
また、巻上機用ロープについては、その端部を昇降路天井に直接固定するようにしてもよい。
また、上記の実施の形態では、釣合重り２０に制御装置１１が搭載されているが、この発明は、釣合重りに制御装置１１が搭載されていないエレベータにも適用することができるのは勿論である。Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. The same reference numerals are used to describe the same members, corresponding parts, and parts as those of the conventional one.
Embodiment 1 FIG.
FIG. 1 is a configuration diagram of an elevator according to Embodiment 1 of the present invention.
The elevator includes a car 1 that moves up and down in the hoistway, a balance weight 20 that moves up and down in conjunction with the car 1, and two hoisting machines 22 a and 22 b mounted on the balance weight 20. And the control device 11 that is mounted on the hoisting machines 22a and 22b and controls the driving of the hoisting machines 22a and 22b, one end of which is connected to the car 1, and the other end is a suspension wheel 23 and a return wheel. 24, the car rope 21 connected to the control device 11 through the upper end is connected to the ceiling of the hoistway via a tension controller 26, the lower end is connected to the floor of the hoistway, and the intermediate part Are provided with hoisting machine ropes 27a and 27b wound around the hoisting machines 22a and 22b, respectively.
The hoisting machines 22a and 22b have the same specifications. Further, the counterweight 20, the hoisting machines 22a and 22b, and the control device 11 are already integrated before the installation of the elevator, that is, at the time of shipment from the manufacturing factory, and constitute the weight main body 25.
The hoisting machines 22a and 22b are within the outer shape of the counterweight 22 when viewed along the extension line of the hoistway.
Further, the hoisting ropes 27a and 27b are resin ropes or resin-coated ropes and have flexibility and can be wound around the hoisting machines 22a and 22b by 360 °. In addition, the tension controller 26 allows the hoisting machine ropes 27a and 27b to extend over time, so that a constant tension can always be obtained against vibration and the like.
In the elevator, for example, when the hoisting machines 22a and 22b are synchronously driven in the counterclockwise direction in FIG. 1, the weight body 25 including the hoisting machines 22a and 22b around which the hoisting machine ropes 27a and 27b are wound, Although it rises, the car 1 descends in conjunction with the weight body 25.
Further, when the hoisting machines 22a and 22b rotate in the clockwise direction in FIG. 1, the weight main body 25 including the hoisting machines 22a and 22b around which the hoisting machine ropes 27a and 27b are wound is lowered. The car 1 moves up in conjunction with the weight body 25.
In the elevator configured as described above, the counterweight 20 is equipped with the same two hoisting machines 22a and 22b, and is not a hoisting machine with special specifications for the capacity and speed of the car 1 but 2 This is handled by the hoisting machines 22a and 22b that are driven synchronously. By adopting such a configuration, there is no need to prepare a hoisting machine with a dedicated specification for the capacity and speed of the car.
Further, since the hoisting machines 22a and 22b are the same (shape, size, and output), installation work and component management are simple, and maintenance is also easy.
Further, the hoisting machine ropes 27a and 27b and the car rope 21 are separate, and an optimum rope can be selected according to each use situation, and the load on the ropes 27a and 27b and the car rope 21 accordingly. Can be reduced to extend the service life, and the entire rope is not uniformly exchanged. It is only necessary to exchange the rope that needs to be exchanged.
Further, a tension controller 26 for stretching the hoisting machine ropes 27a and 27b is fixed to the ceiling, and the tension controller 26 is adjusted so that the tension of the hoisting machine ropes 27a and 27b is always constant. Therefore, it is possible to prevent the hoisting machine ropes 27a and 27b from being displaced in the axial direction from the hoisting machines 22a and 22b during the driving of the hoisting machines 22a and 22b, and the driving force of the hoisting machines 22a and 22b. Is reliably transmitted as the lifting force of the weight body 25 and the car 1.
Further, since the hoisting ropes 27a and 27b are flexible ropes, the hoisting ropes 27a and 27b can be easily wound around the hoisting machines 22a and 22b having a small curvature radius.
Further, since the hoisting machines 22a and 22b have outer dimensions that fit within the outer shape of the counterweight 20 when viewed along the extension line of the hoistway, the plane area for the hoisting machines 22a and 22b is large. There is no increase.
In addition, since the counterweight 20, the hoisting machines 22a and 22b and the control device 11 are integrated in advance before installation, the counterweight 20, the hoisting machines 22a and 22b and the control device 11 are installed on site. Time is shortened. Before installation, for example, the counterweight 20 and the hoisting machines 22a and 22b may be integrated in advance, or the hoisting machines 22a and 22b and the control device 11 may be integrated.
In the above-described embodiment, the two hoisting machines 22a and 22b are mounted on the counterweight 20, and the elevator including the car rope 21 and the hoisting machine ropes 27a and 27b has been described. In an elevator in which a car and a counterweight are suspended by a single rope, a plurality of hoisting machines may be mounted on the counterweight.
Further, in an elevator in which one hoisting machine is mounted on a counterweight, a car may be hung by a car rope, and the hoisting machine may be hung by a hoisting machine rope.
Further, the number of hoisting machines may be three or more.
Moreover, you may make it fix the end part about the rope for hoisting machines directly to a hoistway ceiling.
Further, in the above embodiment, the control device 11 is mounted on the counterweight 20, but the present invention can also be applied to an elevator in which the control device 11 is not mounted on the counterweight. Of course.

以上のように、この発明は、専用仕様の巻上機を用意する必要性が無いという点で、巻上機が釣合重りに搭載されたエレベータに有用である。  As described above, the present invention is useful for an elevator in which a hoisting machine is mounted on a counterweight in that there is no need to prepare a hoisting machine with a dedicated specification.
