Abstract

An elevator has a drive device disposed in the elevator shaft. The drive device is provided with a rotatable drive sheave. In the elevator shaft, a deflector wheel is also disposed with a spacing to the drive sheave. A main rope for suspending a cage and a counterweight is run on the drive sheave and the deflector wheel. The drive device and the deflector wheel are arranged outside the region of the cage in the vertical projection plane of the elevator shaft. Horizontal cross-sectional area of the elevator shaft can be reduced by adjusting the positions of the drive device and the deflector wheel.

エレべ一夕装置 技術分野  Elevator equipment Technical field
この発明は、 かご及び釣合おもりを昇降させる駆動装置 (巻上機) が昇降路内 に配置されたエレべ一夕装置 (いわゆる機械室レスエレべ一夕装置) に関するも のである。 背景技術  The present invention relates to an elevator device (a so-called machine room-less elevator device) in which a driving device (a hoist) for raising and lowering a car and a counterweight is disposed in a hoistway. Background art
従来、 建物におけるエレべ一夕装置の占有空間を縮小するために、 昇降路内に 卷上機を配置するいわゆる機械室レスエレべ一夕装置が提案されている。 特許第 Conventionally, in order to reduce the space occupied by the elevator device in a building, a so-called machine roomless elevator device in which a hoist is arranged in a hoistway has been proposed. Patent No.
2 5 9 3 2 8 8号公報に示されている従来の機械室レスエレべ一夕装置では、 巻 上機は、 昇降路内の上部に配置され、 かつ昇降路を垂直投影したとき、 かごの領 域外に配置されている。 卷上機の駆動シーブには、 かご及び釣合おもりを吊り下 げる主ロープが卷き掛けられている。 かごの下部には、 一対のかご吊り車が設け られている。 また、 釣合おもりの上部には、 釣合おもり吊り車が設けられている。 主ロープは、 昇降路上部の一方の綱止め部から、 各かご吊り車、 駆動シーブ及び 釣合おもり吊り車の順に卷き掛けられ、 昇降路上部の他方の綱止め部に至ってい る。 かごは一対のかごガイ ドレールに案内されて昇降され、 釣合おもりは一対の 釣合おもりガイ ドレールに案内されて昇降される。 In the conventional machine-room-less elevator apparatus disclosed in Japanese Patent Publication No. 25593288, the hoist is arranged at the upper part of the hoistway and when the hoistway is vertically projected, It is located outside the area. The main rope for suspending the car and the counterweight is wound around the drive sheave of the hoist. At the bottom of the car, there is a pair of car suspension wheels. In addition, a counterweight lifting wheel is provided above the counterweight. The main rope is wound around one of the cleats at the upper part of the hoistway in the order of each car hoisting wheel, drive sheave, and counterweight hoisting wheel, and reaches the other cleat at the upper part of the hoistway. The car is guided up and down by a pair of car guide rails, and the counterweight is lifted and guided by a pair of counterweight guide rails.
しかし、 このようなエレべ一夕装置では、 駆動シーブからの主ロープがかご吊 り車及び釣合おもり吊り車に直接巻き掛けられているので、 昇降路の垂直投影面 内において、 かご吊り車及び釣合おもり吊り車に接近させて駆動シーブを配置し なければならず、 昇降路内における卷上機の設置可能範囲が制限されてしまう。 また、 通常、 かご吊り車と釣合おもり吊り車との間には、 かごガイ ドレール及 び釣合おもりガイ ドレールが配置されているので、 卷上機の設置スペースを確保 するために昇降路内の水平断面積を広げる必要があり、 上記のような巻上機の設 置可能範囲の制限が昇降路内の空間の縮小化の妨げにもなる。 発明の開示 However, in such an elevator system, the main ropes from the drive sheave are directly wound around the car hoist and the counterweight hoist. In addition, the drive sheave must be arranged close to the counterweight lifting wheel, which limits the installation range of the hoisting machine in the hoistway. Usually, a cage guide rail and a counterweight guide rail are located between the car suspension wheel and the counterweight suspension wheel. It is necessary to increase the horizontal cross-sectional area of the hoisting machine, and the above-mentioned limitation on the installation range of the hoisting machine also hinders the reduction of the space in the hoistway.

At the upper end of the counterweight 5, a counterweight lifting wheel 13 around which the main rope 11 is wound is provided. Have been. In this example, the straight line connecting the car suspension wheels 12 is parallel to the straight line connecting the car guide rails 2a and 2b.
かごガイ ドレール 2 bの上部には、 第 1の綱止め部 1 4が固定されている。 支 持部材 6には、 第 2の綱止め部 1 5が固定されている。 主索 1 1は、 第 1の綱止 め部 1 4に接続された第 1の端部 1 1 aと、 第 2の綱止め部 1 5に接続された第 2の端部 1 l bとを有している。 また、 主索 1 1は、 第 1の端部 1 1 aから、 一 対のかご吊り車 1 2、 そらせ車 1 0、 駆動シーブ 9、 及び釣合おもり吊り車 1 3 の順に巻き掛けられ、 第 2の端部 1 1 bに至っている。 即ち、 主索 1 1は、 駆動 シ一ブ 9及びそらせ車 1 0に巻き掛けられ、 一端部側でかご 4を吊り下げ、 他端 部側で釣合おもり 5を吊り下げている。 さらに、 主索 1 1は、 一対のかご吊り車 1 2、 そらせ車 1 0、 駆動シ一ブ 9、 及び釣合おもり吊り車 1 3との滑りを防止 するために、 高い摩擦係数を有する高摩擦材 (樹脂) により構成された図示しな い外層部 (被覆材) を有している。  A first rope stopper 14 is fixed to an upper portion of the car guide rail 2b. A second cleat 15 is fixed to the support member 6. The main rope 11 has a first end 11 a connected to the first cleat 14 and a second end 1 lb connected to the second cleat 15. Have. Also, the main rope 11 is wound from the first end 11a in the order of a pair of car suspension wheels 12, a deflector wheel 10, a drive sheave 9, and a counterweight suspension wheel 13, It reaches the second end 11b. That is, the main rope 11 is wound around the drive sheave 9 and the deflector wheel 10, and suspends the car 4 at one end and the counterweight 5 at the other end. Further, the main rope 11 has a high coefficient of friction to prevent slippage between the pair of car suspension wheels 12, the deflecting wheel 10, the drive sheave 9, and the counterweight suspension wheel 13. It has an unillustrated outer layer (covering material) made of friction material (resin).
このようなエレべ一夕装置では、 昇降路 1の垂直投影面内において、 駆動装置 7及びそらせ車 1 3がかご 4の領域外に配置されているので、 かご 4の天井が駆 動装置 7及びそらせ車 1 3の設置高さを超える位置までかご 4を上昇させること ができ、 しかも昇降路 1の垂直投影面内において、 駆動シ一ブ 9をかご吊り車 1 2から離して配置することができるので、 かご吊り車 1 2及び釣合おもり吊り車 1 3の両方に接近させて駆動シーブ 9 を配置する必要がなくなり、 昇降路 1内で の駆動装置 7の設置可能範囲を広くすることができる。 これにより、 かごガイ ド レール 2 a及び釣合おもりガイ ドレ一 レ 3 a等の干渉を避けて、 かご 4に対して より近い位置に駆動装置 7を配置することができ、 昇降路 1内の空間の縮小化を 図ることができる。  In such an elevator system, since the driving device 7 and the deflector 13 are arranged outside the area of the car 4 in the vertical projection plane of the hoistway 1, the ceiling of the car 4 is The car 4 can be raised to a position exceeding the height of the deflector 13 and the drive sheave 9 should be placed away from the car suspension car 12 in the vertical projection plane of the hoistway 1. Therefore, it is not necessary to dispose the drive sheave 9 in close proximity to both the car hoisting wheel 12 and the counterweight hoisting wheel 13, and the installation range of the driving device 7 in the hoistway 1 can be increased. Can be. As a result, the driving device 7 can be arranged at a position closer to the car 4 while avoiding interference between the car guide rail 2a and the counterweight guide rail 3a, and the like. The space can be reduced.
また、 そらせ車 1 0、 かご吊り車 1 2及びかごガイ ドレール 2 aのそれぞれの 位置を変更することにより、 釣合おも りガイ ドレール 3 a, 3 b間の間隔を広げ て釣合おもり 5の幅方向の寸法を大き くすることができるので、 釣合おもり 5の 厚さ方向の寸法を小さくすることができ、 昇降路 1内の空間の縮小化を図ること ができる。  Also, by changing the positions of the deflecting wheel 10, the car suspension wheel 12 and the car guide rail 2a, the distance between the counterweight guide rails 3a and 3b is increased and the counterweight 5 is increased. Since the dimension of the counterweight 5 in the width direction can be increased, the dimension of the counterweight 5 in the thickness direction can be reduced, and the space in the hoistway 1 can be reduced.
また、 昇降路 1の垂直投影面内において、 駆動装置 7が釣合おもり 5の領域内 に配置されているので、 昇降路 1内の上下方向についての空間を有効に利用する ことができる。 さらに、 釣合おもり 5の厚さの範囲内に駆動装置 7を配置するこ とができるので、 昇降路 1内の空間の縮小化をさらに図ることができる。 Also, in the vertical projection plane of the hoistway 1, the driving device 7 The space in the vertical direction in the hoistway 1 can be used effectively. Furthermore, since the driving device 7 can be arranged within the range of the thickness of the counterweight 5, the space in the hoistway 1 can be further reduced.
さらに、 主索 1 1は、 高摩擦材により構成された外層部を有しているので、 駆 動シーブ 9、 そらせ車 1 0、 一対のかご吊り車 1 2及び釣合おもり吊り車 1 3に 対する主索 1 1の滑りを防止することができる。  Further, since the main rope 11 has an outer layer portion made of a high friction material, the main sheave 9 includes a driving sheave 9, a deflecting wheel 10, a pair of car hanging wheels 12 and a counterweight hanging wheel 13. The main rope 1 1 can be prevented from slipping.
