　実施の形態１．
　図１はこの発明の実施の形態１によるエレベータ装置を示す概略の構成図である。図において、昇降路１内には、第１及び第２のかごガイドレール２，３と、第１及び第２の釣合おもりガイドレール４，５とが設置されている。 Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Embodiment 1 FIG.
1 is a schematic configuration diagram showing an elevator apparatus according to Embodiment 1 of the present invention. In the figure, first and second car guide rails 2 and 3 and first and second counterweight guide rails 4 and 5 are installed in a hoistway 1.
　昇降体であるかご６は、第１及び第２のかごガイドレール２，３間に配置されており、第１及び第２のかごガイドレール２，３に案内されて昇降路１内を昇降される。釣合おもり７は、第１及び第２の釣合おもりガイドレール４，５間に配置されており、第１及び第２の釣合おもりガイドレール４，５に案内されて昇降路１内を昇降される。 A car 6 as a lifting body is disposed between the first and second car guide rails 2 and 3 and is guided up and down in the hoistway 1 by being guided by the first and second car guide rails 2 and 3.

Go up and down.
　かご６の上部には、第１のかごガイドレール２に沿って移動する第１のかご上部ローラガイド装置８と、第２のかごガイドレール３に沿って移動する第２のかご上部ローラガイド装置９とが設けられている。 A first car upper roller guide device 8 that moves along the first car guide rail 2 and a second car upper roller guide device that moves along the second car guide rail 3 are disposed above the car 6. 9 are provided.
　かご６の下部には、第１のかごガイドレール２に沿って移動する第１のかご下部ローラガイド装置１０と、第２のかごガイドレール３に沿って移動する第２のかご下部ローラガイド装置１１とが設けられている。 Below the car 6 are a first car lower roller guide device 10 that moves along the first car guide rail 2 and a second car lower roller guide device that moves along the second car guide rail 3. 11 is provided.
　釣合おもり７の上部には、第１の釣合おもりガイドレール４に沿って移動する第１の釣合おもり上部ローラガイド装置１２と、第２の釣合おもりガイドレール５に沿って移動する第２の釣合おもり上部ローラガイド装置１３とが設けられている。 In the upper part of the counterweight 7, the first counterweight upper roller guide device 12 that moves along the first counterweight guide rail 4 and the second counterweight guide rail 5 moves along. A second counterweight upper roller guide device 13 is provided.
　釣合おもり７の下部には、第１の釣合おもりガイドレール４に沿って移動する第１の釣合おもり下部ローラガイド装置１４と、第２の釣合おもりガイドレール５に沿って移動する第２の釣合おもり下部ローラガイド装置１５とが設けられている。各ローラガイド装置８～１５は、複数のガイドローラを有している。 The lower portion of the counterweight 7 moves along the first counterweight lower roller guide device 14 that moves along the first counterweight guide rail 4 and the second counterweight guide rail 5. A second counterweight lower roller guide device 15 is provided. Each of the roller guide devices 8 to 15 has a plurality of guide rollers.
　昇降路１の上部には、巻上機（駆動装置）１６が設置されている。巻上機１６は、駆動シーブ１７と巻上機本体１８とを有している。巻上機本体１８は、駆動シーブ１７を回転させる巻上機モータ（図示せず）と、駆動シーブ１７の回転を制動する巻上機ブレーキ（図示せず）とを有している。 A hoisting machine (driving device) 16 is installed at the top of the hoistway 1. The hoisting machine 16 includes a drive sheave 17 and a hoisting machine main body 18. The hoisting machine body 18 includes a hoisting machine motor (not shown) that rotates the driving sheave 17 and a hoisting machine brake (not shown) that brakes the rotation of the driving sheave 17.
　駆動シーブ１７には、懸架手段１９が巻き掛けられている。懸架手段１９としては、複数本のロープ又は複数本のベルトが用いられている。かご６及び釣合おもり７は、懸架手段１９により吊り下げられており、巻上機１６により昇降路１内を昇降される。 The suspension means 19 is wound around the drive sheave 17. As the suspension means 19, a plurality of ropes or a plurality of belts are used. The car 6 and the counterweight 7 are suspended by the suspension means 19 and are raised and lowered in the hoistway 1 by the hoisting machine 16.
　また、かご６の下部には、非常時に第１及び第２のかごガイドレール２，３を把持してかご６を停止させる非常止め装置２０が搭載されている。非常止め装置２０は、例えば調速機（図示せず）により作動される。 In addition, an emergency stop device 20 that holds the first and second car guide rails 2 and 3 and stops the car 6 in an emergency is mounted below the car 6. The emergency stop device 20 is operated by, for example, a speed governor (not shown).
　調速機には、かご６の異常速度の閾値として、定格速度よりも高い第１の過大速度（ＯＳ速度）と、第１の過大速度よりも高い第２の過大速度（Ｔｒｉｐ速度）とが予め設定されている。調速機は、かご６の速度が第１の過大速度に達すると、巻上機モータへの通電を遮断するとともに、巻上機ブレーキを作動させる。また、調速機は、かご６の速度が第２の過大速度に達すると非常止め装置２０を作動させる。 The speed governor has a first overspeed (OS speed) higher than the rated speed and a second overspeed (Trip speed) higher than the first overspeed as thresholds for the abnormal speed of the car 6. It is set in advance. When the speed of the car 6 reaches the first excessive speed, the governor cuts off the power to the hoisting machine motor and activates the hoisting machine brake. Further, the speed governor activates the emergency stop device 20 when the speed of the car 6 reaches the second excessive speed.
　かご６には、非常止め装置２０に対して上下方向に間隔をおいて水平変位規制装置２１が搭載されている。この例では、非常止め装置２０がかご６の下部に搭載されているのに対して、水平変位規制装置２１はかご６の上部に搭載されている。 A horizontal displacement regulating device 21 is mounted on the car 6 with a space in the vertical direction with respect to the safety device 20. In this example, the emergency stop device 20 is mounted on the lower portion of the car 6, while the horizontal displacement regulating device 21 is mounted on the upper portion of the car 6.
　水平変位規制装置２１は、非常止め装置２０の作動時に第１及び第２のかごガイドレール２，３に対するかご６の水平方向への変位を規制する。また、非常止め装置２０の作動時には、かご６は、水平変位規制装置２１とかごガイドレール２，３との間の摩擦力の有無によらず、非常止め装置２０の制動力によって非常停止される。 The horizontal displacement regulating device 21 regulates the displacement of the car 6 in the horizontal direction with respect to the first and second car guide rails 2 and 3 when the safety device 20 is operated. Further, when the emergency stop device 20 is operated, the car 6 is emergency stopped by the braking force of the emergency stop device 20 regardless of the presence or absence of the frictional force between the horizontal displacement regulating device 21 and the car guide rails 2 and 3. .
　即ち、水平変位規制装置２１は、非常止め装置２０の作動時にかご６の水平方向への変位を規制するものであり、結果的にかごガイドレール２，３との間にある程度の摩擦力が発生したとしても、かご６の非常停止動作に必要とされるものではない。 That is, the horizontal displacement regulating device 21 regulates the displacement of the car 6 in the horizontal direction when the safety device 20 is operated, and as a result, a certain amount of frictional force is generated between the car guide rails 2 and 3. Even if it does, it is not required for the emergency stop operation of the car 6.
　また、水平変位規制装置２１は、通常時（非常止め装置２０の非作動時）には、第１及び第２のかごガイドレール２，３に対するかご６の水平方向への変位を規制せず許容する。 Further, the horizontal displacement restricting device 21 does not restrict the displacement of the car 6 in the horizontal direction relative to the first and second car guide rails 2 and 3 during normal times (when the safety device 20 is not in operation). To do.
　図２は図１のかご６の非常止め装置２０作動時の状態を示す平面図である。かご６の上部には、上梁２２が固定されている。懸架手段１９は、上梁２２の中間部に接続されている。昇降路１内には、上下方向に互いに間隔をおいて複数のレールブラケット２３が固定されている。かごガイドレール２，３は、複数組のレールクリップ２４によりレールブラケット２３に締結されている。 FIG. 2 is a plan view showing a state when the safety device 20 of the car 6 of FIG. 1 is operated.

　水平変位規制装置２１は、上梁２２の第１のかごガイドレール２側の端部に固定された第１の変位規制部２５と、上梁２２の第２のかごガイドレール３側の端部に固定された第２の変位規制部２６とを有している。 The horizontal displacement restricting device 21 includes a first displacement restricting portion 25 fixed to an end portion of the upper beam 22 on the first car guide rail 2 side, and an end portion of the upper beam 22 on the second car guide rail 3 side. And a second displacement restricting portion 26 fixed to the head.
　変位規制部２５，２６は、上梁２２に固定されたＵ字形の固定部材２７と、固定部材２７に変位可能に設けられた一対の可動部材２８ａ，２８ｂとをそれぞれ有している。可動部材２８ａ，２８ｂは、第１及び第２のかごガイドレール２，３に対するかご６の水平方向への変位を規制する規制位置と、規制位置よりも第１及び第２のかごガイドレール２，３から離れた離隔位置との間で変位可能となっている。図２では、全ての可動部材２８ａ，２８ｂが規制位置に変位している。 The displacement restricting portions 25 and 26 each have a U-shaped fixed member 27 fixed to the upper beam 22 and a pair of movable members 28a and 28b provided on the fixed member 27 so as to be displaceable. The movable members 28a and 28b include a restriction position for restricting the horizontal displacement of the car 6 with respect to the first and second car guide rails 2 and 3, and the first and second car guide rails 2 and 2 from the restriction position. It is possible to displace between a remote position away from 3. In FIG. 2, all the movable members 28a and 28b are displaced to the restriction positions.
　また、図２では、非常止め装置２０の作動時にかご６に偏荷重がかかり、かご６の上部が第２のかごガイドレール２側へ変位している。これに対して、第１の変位規制部２５の固定部材２７が第１のかごガイドレール２の先端面に当たることにより、第１のかごガイドレール２に対するかご６の水平方向への変位が規制されている。 Further, in FIG. 2, an eccentric load is applied to the car 6 when the safety device 20 is operated, and the upper part of the car 6 is displaced toward the second car guide rail 2 side.

　図３は図２の第１の変位規制部２５を拡大して示す平面図、図４は図３の可動部材２８ａ，２８ｂが規制位置に変位した状態を示す平面図である。固定部材２７と可動部材２８ａ，２８ｂとの間には、可動部材２８ａ，２８ｂを規制位置（図４）と離隔位置（図３）との間で変位させる一対のアクチュエータ２９ａ，２９ｂと、可動部材２８ａ，２８ｂの直線移動を案内する一対のスライドガイド機構３０ａ，３０ｂとが設けられている。第２の変位規制部２６の構成は、第１の変位規制部２５と同じである。 3 is an enlarged plan view showing the first displacement restricting portion 25 of FIG. 2, and FIG. 4 is a plan view showing a state where the movable members 28a and 28b of FIG. 3 are displaced to the restricting positions. Between the fixed member 27 and the movable members 28a and 28b, a pair of actuators 29a and 29b for displacing the movable members 28a and 28b between the restriction position (FIG. 4) and the separation position (FIG. 3), and the movable member A pair of slide guide mechanisms 30a and 30b for guiding the linear movement of 28a and 28b are provided. The configuration of the second displacement regulating unit 26 is the same as that of the first displacement regulating unit 25.
　図５は図１のかご６を拡大して示す正面図である。非常止め装置２０には、作動レバー（引き上げレバー）３１が設けられている。作動レバー３１には、調速機の調速機シーブに巻き掛けられたループ状の調速機ロープ３２が接続されている。 FIG. 5 is an enlarged front view showing the car 6 of FIG. The emergency stop device 20 is provided with an operation lever (lift lever) 31. A loop-shaped governor rope 32 wound around the governor sheave of the governor is connected to the operating lever 31.
　調速機ロープ３２は、通常時には、かご６の昇降に伴って循環移動される。しかし、かご６の下降速度が第２の過大速度に達すると、調速機により調速機ロープ３２の循環移動が停止される。調速機ロープ３２の循環移動が停止されると、かご６の下降により作動レバー３１が引き上げられ、これにより非常止め装置２０が作動する。 The governor rope 32 is circulated and moved as the car 6 moves up and down during normal times. However, when the descending speed of the car 6 reaches the second overspeed, the governor stops the circulating movement of the governor rope 32. When the circulating movement of the governor rope 32 is stopped, the operating lever 31 is pulled up by the lowering of the car 6, and thereby the emergency stop device 20 is operated.
　非常止め装置２０には、非常止め装置２０の作動を検出する作動検出部が設けられている。この例では、作動検出部として、作動検出スイッチ３３が用いられている。作動検出スイッチ３３の接点は、通常時は閉じられており、作動レバー３１が引き上げられると開放される。作動検出スイッチ３３の接点が開放されると、その信号（図の破線矢印）に応じて、アクチュエータ２９ａ，２９ｂにより可動部材２８ａ，２８ｂが規制位置に変位される。 The emergency stop device 20 is provided with an operation detection unit that detects the operation of the emergency stop device 20. In this example, an operation detection switch 33 is used as the operation detection unit. The contact of the operation detection switch 33 is normally closed, and is opened when the operation lever 31 is pulled up. When the contact of the operation detection switch 33 is opened, the movable members 28a and 28b are displaced to the restriction positions by the actuators 29a and 29b in accordance with the signal (broken arrow in the figure).
　このようなエレベータ装置では、非常止め装置２０の作動時に、第１及び第２の変位規制部２５，２６により、第１及び第２のかごガイドレール２，３に対するかご６の水平方向への変位が規制（所定の範囲内に制限）される。これにより、特にかごガイドレール２，３に対してかご６が離れる方向へ動く場合に、第１及び第２のかごガイドレール２，３が同じ方向に変位するような水平力（かご６の動きに合わせてかごガイドレール２，３を変形させるような力）がかご６とかごガイドレール２，３との間に発生する。 In such an elevator apparatus, when the safety device 20 is operated, the first and second displacement restricting portions 25 and 26 cause the car 6 to be displaced in the horizontal direction with respect to the first and second car guide rails 2 and 3. Is regulated (limited to a predetermined range). Thus, particularly when the car 6 moves away from the car guide rails 2 and 3, the horizontal force (the movement of the car 6) is such that the first and second car guide rails 2 and 3 are displaced in the same direction. (A force that deforms the car guide rails 2 and 3) is generated between the car 6 and the car guide rails 2 and 3.
　従って、かご上部ローラガイド装置８，９の片当たりを防止し、かごガイドレール２，３の強度を低減することができる。また、非常止め装置２０を２組用いる場合に比べ、構成を簡単にすることができる。 Therefore, it is possible to prevent the car upper roller guide devices 8 and 9 from coming into contact with each other and reduce the strength of the car guide rails 2 and 3. Further, the configuration can be simplified as compared with the case where two sets of the emergency stop devices 20 are used.
　また、可動部材２８ａ，２８ｂが規制位置と離隔位置との間で変位可能になっているため、かご６の通常走行時に可動部材２８ａ，２８ｂがかごガイドレール２，３に干渉することがなく、騒音、振動及び走行ロスの発生を防止することができる。 Further, since the movable members 28a and 28b can be displaced between the restriction position and the separation position, the movable members 28a and 28b do not interfere with the car guide rails 2 and 3 during the normal traveling of the car 6. Generation of noise, vibration and travel loss can be prevented.
　さらに、作動検出スイッチ３３により非常止め装置２０の作動が検出されると、アクチュエータ２９ａ，２９ｂにより可動部材２８ａ，２８ｂが規制位置に変位されるので、可動部材２８ａ，２８ｂを変位させるための構成をコンパクト化することができる。 Further, when the operation of the safety device 20 is detected by the operation detection switch 33, the movable members 28a and 28b are displaced to the restricting positions by the actuators 29a and 29b, so that the movable members 28a and 28b are displaced. It can be made compact.
　なお、実施の形態１では２つのアクチュエータ２９ａ，２９ｂを用いたが、１つのアクチュエータの駆動力を２つの可動部材２８ａ，２８ｂに伝達するようにしてもよい。 Although the two actuators 29a and 29b are used in the first embodiment, the driving force of one actuator may be transmitted to the two movable members 28a and 28b.

　摩擦保持部８９ａ，８９ｂは、可動部材６６ａ，６６ｂが規制位置に位置するときに、かごガイドレール２から離れようとする方向（図のＸ軸方向）へのかご６の変位に抵抗する摩擦力を発生する。かご６の昇降方向（図のＺ軸方向）への摩擦保持部８９ａ，８９ｂのかごガイドレール２に対する摩擦力は、Ｘ軸方向への摩擦力に比べて十分に小さい。 The friction holding portions 89a and 89b are frictional forces that resist displacement of the car 6 in a direction (X-axis direction in the figure) in which the movable members 66a and 66b are located at the restriction positions. Is generated. The frictional force of the friction holding portions 89a and 89b with respect to the car guide rail 2 in the ascending / descending direction of the car 6 (Z-axis direction in the figure) is sufficiently smaller than the frictional force in the X-axis direction.
　通常運転時には、楔部６７は図２２に示す下降位置に位置しており、可動部材６６ａ，６６ｂは図３０に示す離隔位置に位置している。 During normal operation, the wedge portion 67 is located at the lowered position shown in FIG. 22, and the movable members 66a and 66b are located at the separated positions shown in FIG.
　これに対して、非常止め装置２０の作動が検出されると、アクチュエータ６８（図２２）により楔部６７が上昇位置（図２３、２４）まで持ち上げられ、可動部材６６ａ，６６ｂが楔部６７により押圧される。これにより、可動部材６６ａ，６６ｂの楔部６７が接している部分の間隔が押し広げられ、逆に、可動部材６６ａ，６６ｂのガイド部２ｂに対向する部分の間隔が狭められ、可動部材６６ａ，６６ｂが規制位置まで変位される。 On the other hand, when the operation of the safety device 20 is detected, the wedge portion 67 is lifted to the raised position (FIGS. 23 and 24) by the actuator 68 (FIG. 22), and the movable members 66a and 66b are moved by the wedge portion 67. Pressed. As a result, the interval between the portions of the movable members 66a and 66b where the wedge portions 67 are in contact with each other is increased, and conversely, the interval between the portions of the movable members 66a and 66b facing the guide portion 2b is reduced, and the movable members 66a and 66b are reduced. 66b is displaced to the restriction position.
　第２の変位規制部の構成は、第１の変位規制部と同じである。また、第１及び第２の変位規制部以外の構成は、実施の形態１と同様である。 The configuration of the second displacement regulating unit is the same as that of the first displacement regulating unit. The configuration other than the first and second displacement regulating portions is the same as that of the first embodiment.
　このような第１及び第２の変位規制部によっても、実施の形態１１と同様の効果を得ることができる。 The same effects as those of the eleventh embodiment can also be obtained by such first and second displacement regulating portions.
　なお、実施の形態１３、１４に示したように、実施の形態１～１２の構成は適宜組み合わせることが可能である。例えば、実施の形態９、１０、１１を組み合わせて、図３０の楔部６７を作動レバー３１に機械的に連動させて上昇位置へ変位するようにしてもよい。 As shown in the thirteenth and fourteenth embodiments, the configurations of the first to twelfth embodiments can be appropriately combined. For example, the wedge portions 67 of FIG. 30 may be mechanically interlocked with the operating lever 31 and displaced to the raised position by combining Embodiments 9, 10, and 11.
　実施の形態１５．
　次に、図３１はこの発明の実施の形態１５による第１の変位規制部を示す平面図である。実施の形態１５の第１の変位規制部は、電磁石８６を有している。電磁石８６は、かごガイドレール２のかご６側端面に対向してかご６に搭載されている。 Embodiment 15 FIG.
Next, FIG. 31 is a plan view showing a first displacement regulating portion according to Embodiment 15 of the present invention. The first displacement restricting portion of the fifteenth embodiment has an electromagnet 86. The electromagnet 86 is mounted on the car 6 so as to face the car 6 side end surface of the car guide rail 2.
　通常運転時には、電磁石８６への通電は遮断されている。これに対して、非常止め装置２０の作動が検出されると、電磁石８６が励磁され、電磁石８６がかごガイドレール２に吸着される。第２の変位規制部の構成は、第１の変位規制部と同じである。また、他の構成は、実施の形態１と同様である。 During normal operation, power to the electromagnet 86 is cut off. On the other hand, when the operation of the safety device 20 is detected, the electromagnet 86 is excited and the electromagnet 86 is attracted to the car guide rail 2. The configuration of the second displacement regulating unit is the same as that of the first displacement regulating unit. Other configurations are the same as those in the first embodiment.
　このような第１及び第２の変位規制部によっても、かご上部ローラガイド装置８，９の片当たりを防止し、かごガイドレール２，３の強度を低減することができる。また、非常止め装置２０を２組用いる場合に比べ、構成を簡単にすることができる。 Such first and second displacement restricting portions can also prevent the car upper roller guide devices 8 and 9 from coming into contact with each other and reduce the strength of the car guide rails 2 and 3. Further, the configuration can be simplified as compared with the case where two sets of the emergency stop devices 20 are used.
　なお、水平変位規制装置の位置はかご６の上部に限定されるものではなく、例えばかご６の上下方向の中間部であってもよい。例えば、非常止め装置２０がかご６に配置されている場合、水平変位規制装置をかご６の下部に配置してもよい。
　また、２組以上の水平変位規制装置をかご６に搭載してもよい。 Note that the position of the horizontal displacement regulating device is not limited to the upper part of the car 6, and may be, for example, an intermediate part in the vertical direction of the car 6. For example, when the safety device 20 is disposed in the car 6, the horizontal displacement regulating device may be disposed in the lower part of the car 6.
Two or more sets of horizontal displacement regulating devices may be mounted on the car 6.
　さらに、上記の実施の形態１～１５では、２本のかごガイドレール２，３を示したが、３本以上のガイドレールにより昇降体の昇降が案内されるエレベータ装置にもこの発明は適用できる。例えば、かごの両側に２本ずつのかごガイドレールが配置されている場合、４本のかごガイドレールに対応する４個の変位規制部を用いてもよい。即ち、第３のガイドレール以降を追加、又は第１及び第２のガイドレールを２本以上ずつ設けてもよい。これに伴い、第３の変位規制部を追加、又は第１及び第２の変位規制部を２個以上ずつ用いてもよい。 Furthermore, in the above-described first to fifteenth embodiments, the two car guide rails 2 and 3 are shown. However, the present invention can also be applied to an elevator apparatus in which the lifting and lowering body is guided by three or more guide rails. . For example, when two car guide rails are arranged on both sides of the car, four displacement restricting portions corresponding to the four car guide rails may be used. That is, the third guide rail and subsequent ones may be added, or two or more first and second guide rails may be provided. Accordingly, a third displacement restriction part may be added, or two or more first and second displacement restriction parts may be used.
　さらにまた、上記の実施の形態１～１５の変位規制部を適宜組み合わせて用いてもよい。
　また、ガイド装置は、スライディングガイドシューでもよい。
　さらに、昇降体は釣合おもりであってもよい。即ち、釣合おもりに非常止め装置が搭載されている場合、水平変位規制装置を釣合おもりに搭載してもよい。 Furthermore, the displacement restricting portions in the first to fifteenth embodiments may be used in appropriate combination.
The guide device may be a sliding guide shoe.
Further, the lifting body may be a counterweight. That is, when the emergency stop device is mounted on the counterweight, the horizontal displacement regulating device may be mounted on the counterweight.
　さらにまた、巻上機の位置やローピング方式等のエレベータ装置全体のレイアウトは、図１のレイアウトに限定されない。
　また、この発明は、機械室を持つエレベータ装置、機械室レスエレベータ、リニアモータエレベータ、油圧エレベータ、ダブルデッキエレベータ、共通の昇降路内に複数のかごが配置されているワンシャフトマルチカー方式のエレベータなど、あらゆるタイプのエレベータ装置に適用できる。 Furthermore, the layout of the entire elevator apparatus, such as the position of the hoisting machine and the roping method, is not limited to the layout of FIG.
The present invention also relates to an elevator apparatus having a machine room, a machine room-less elevator, a linear motor elevator, a hydraulic elevator, a double deck elevator, and a one-shaft multi-car type elevator in which a plurality of cars are arranged in a common hoistway.
