発明を実施するための最良の形態  BEST MODE FOR CARRYING OUT THE INVENTION
[0008] 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。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
実施の形態 1.  Embodiment 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構成図である。図にお いて、昇降路 1内には、力ご 2及び釣合おもり 3が設けられている。力ご 2及び釣合お もり 3は、昇降路 1内に設置された一対のかごガイドレール 4及び釣合おもりガイドレ ール (図示せず）に沿って昇降路 1内を昇降される。  FIG. 1 is a configuration diagram showing an elevator apparatus according to Embodiment 1 of the present invention. In the figure, a lift 2 and a counterweight 3 are provided in the hoistway 1. The force cage 2 and the counterweight 3 are moved up and down in the hoistway 1 along a pair of car guide rails 4 and a counterweight guide rail (not shown) installed in the hoistway 1.
[0009] かご 2の上部には、かごガイドレール 4に係合する一対の上部かごガイドシユー 5が 搭載されている。力ご 2の下部には、力ごガイドレール 4に機械的に係合することによ りかご 2を非常停止させる一対の非常止め装置 6が設けられている。  On the upper part of the car 2, a pair of upper car guide shrouds 5 that engage with the car guide rails 4 are mounted. A pair of emergency stop devices 6 are provided at the lower portion of the force cage 2 to emergency stop the cage 2 by mechanically engaging with the force guide rail 4.
[0010] 昇降路 1の上部の機械室又は昇降路 1内の上部には、力ご 2及び釣合おもり 3を昇 降させる駆動装置 (卷上機) 7が設置されている。駆動装置 7は、モータ部、モータ部 によって回転される駆動シーブ 8、及び駆動シーブ 8の回転を制動するブレーキ部を 有している。ブレーキ部としては、例えば電磁ブレーキ装置が用いられている。電磁 ブレーキ装置においては、制動ばねのばね力によりブレーキシュ一が制動面に押し 付けられて駆動シーブ 8の回転が制動されるとともに、電磁石を励磁することによりブ レーキシュ一が制動面力 開離され、制動が解除される。  [0010] In the machine room at the upper part of the hoistway 1 or in the upper part in the hoistway 1, a driving device (lifting machine) 7 for raising and lowering the force 2 and the counterweight 3 is installed. The drive device 7 includes a motor unit, a drive sheave 8 that is rotated by the motor unit, and a brake unit that brakes the rotation of the drive sheave 8. For example, an electromagnetic brake device is used as the brake unit. In an electromagnetic brake device, the brake shoe is pressed against the braking surface by the spring force of the braking spring to brake the rotation of the drive sheave 8, and the brake force is released by exciting the electromagnet. , Braking is released.
[0011] 駆動装置 7の近傍には、そらせ車 9が配置されている。駆動シーブ 8及びそらせ車 9 には、複数本（図では 1本のみ示す）の主ロープ 10が巻き掛けられている。主ロープ 10の第 1端部 10aには、かご 2が吊り下げられている。主ロープ 10の第 2端部 10bに は、釣合おもり 3が吊り下げられている。即ち、力ご 2及び釣合おもり 3は、主ロープ 10 により 1： 1ロービング方式で昇降路 1内に吊り下げられて 、る。  In the vicinity of the driving device 7, a deflecting wheel 9 is arranged. A plurality of main ropes 10 (only one is shown in the figure) are wound around the drive sheave 8 and the deflector 9. A car 2 is suspended from the first end 10 a of the main rope 10. A counterweight 3 is suspended from the second end 10 b of the main rope 10. That is, the force 2 and the counterweight 3 are suspended in the hoistway 1 by the main rope 10 in a 1: 1 roving manner.
[0012] 昇降路 1の上部には、力ご 2の速度を検出するための調速機 11が設置されている。  A speed governor 11 for detecting the speed of the force 2 is installed at the upper part of the hoistway 1.
調速機 11の調速機シーブには、調速機ロープ 12が巻き掛けられている。昇降路 1の 下部には、調速機張り車 13が配置されている。調速機張り車 13には、調速機ロープ 12の下端部が巻き掛けられている。 [0013] 各非常止め装置 6からは、非常止め装置 6を作動させるための引上棒 14が引き出 されている。引上棒 14は、リンク機構 15を介して互いに連結されている。リンク機構 1 5には、調速機ロープ 12の両端部が連結されている。このため、調速機ロープ 12は 力ご 2の昇降に伴って循環移動され、調速機 11の調速機シーブは、力ご 2の走行速 度に応じた速度で回転される。 A governor rope 12 is wound around the governor sheave of the governor 11. In the lower part of the hoistway 1, a governor wheel 13 is arranged. The governor rope 13 is wound around the lower end of the governor rope 12. [0013] From each emergency stop device 6, a pull-up bar 14 for operating the emergency stop device 6 is pulled out. The pull-up bars 14 are connected to each other via a link mechanism 15. Both ends of the governor rope 12 are connected to the link mechanism 15. For this reason, the governor rope 12 is circulated and moved as the force 2 is raised and lowered, and the governor sheave of the governor 11 is rotated at a speed corresponding to the traveling speed of the force 2.
[0014] かご 2の走行速度が予め設定された第 1過速度に達すると、駆動装置 7のモータ部 及びブレーキ部への通電が遮断され、駆動シーブ 8の回転が制動される。また、かご 2の走行速度 (下降速度)が予め設定された第 2過速度に達すると、調速機 11に設け られたロープキャッチにより調速機ロープ 12の循環が停止され、連結機構 15を介し て引上棒 14が引き上げられ、非常止め装置 6が制動動作する。  When the traveling speed of the car 2 reaches a preset first overspeed, the energization of the motor unit and the brake unit of the drive device 7 is cut off, and the rotation of the drive sheave 8 is braked. In addition, when the traveling speed (downward speed) of the car 2 reaches the preset second overspeed, the circulation of the governor rope 12 is stopped by the rope catch provided in the governor 11, and the coupling mechanism 15 is As a result, the lifting rod 14 is pulled up, and the emergency stop device 6 is braked.
[0015] 図 2は図 1の非常止め装置 6を示す側面図である。力ご 2の下部には、非常止め枠 31が固定されている。非常止め枠 31には、非常止め収容部（又は非常止め取付部） 31aとガイドシユー収容部（又はガイドシユー取付部） 31bとが設けられている。即ち、 非常止め収容部 3 laとガイドシユー収容部 3 lbとは一体品で構成されている。非常 止め枠 31は、例えば鋼板により構成されている。また、ガイドシユー収容部 31bは、 非常止め収容部 3 laの下部に設けられている。  FIG. 2 is a side view showing the safety device 6 of FIG. An emergency stop frame 31 is fixed to the lower portion of the force 2. The emergency stop frame 31 is provided with an emergency stop housing part (or emergency stop mounting part) 31a and a guide shoe housing part (or guide shoe mounting part) 31b. That is, the emergency stop accommodating portion 3 la and the guide shoe accommodating portion 3 lb are integrally formed. The emergency stop frame 31 is made of, for example, a steel plate. The guide shoe housing part 31b is provided at the lower part of the emergency stop housing part 3la.
[0016] 非常止め収容部 31aには、非常止め本体 32が取り付けられ収容されている。非常 止め本体 32は、一対のテーパ部材 33、テーパ部材 33と非常止め収容部 31aとの間 に設けられている複数の押し付けばね 34、テーパ部材 33に対向する一対の制動片 (楔部材） 35、及びテーパ部材 33と制動片 35との間に介在された複数のコロ 36を有 している。非常止め本体 32の構成部品は、かごガイドレール 4を中心に対称に配置 されている。  [0016] An emergency stop main body 32 is mounted and accommodated in the emergency stop accommodating portion 31a. The emergency stop main body 32 includes a pair of taper members 33, a plurality of pressing springs 34 provided between the taper member 33 and the emergency stop accommodating portion 31a, and a pair of braking pieces (wedge members) 35 facing the taper member 33. And a plurality of rollers 36 interposed between the taper member 33 and the braking piece 35. The components of the emergency stop body 32 are arranged symmetrically around the car guide rail 4.
[0017] 各テーパ部材 33には、かごガイドレール 4に対向し、上方へ行くに従ってかごガイ ドレール 4との距離が小さくなるようなテーパ面 33aが設けられている。各制動片 35は 、テーパ面 33aに対向している。また、各制動片 35には、力ごガイドレール 4に対向 する制動面 35aが設けられている。各制動片 35には、引上棒 14が接続されている。  Each taper member 33 is provided with a tapered surface 33a that faces the car guide rail 4 and whose distance from the car guide rail 4 decreases as it goes upward. Each braking piece 35 faces the tapered surface 33a. Each braking piece 35 is provided with a braking surface 35a facing the force guide rail 4. A pulling rod 14 is connected to each braking piece 35.
[0018] 力ご 2の走行速度が第 2過速度に達し、下降するかご 2に対して引上棒 38が引き上 げられると、テーパ部材 33に対して制動片 35が上動される。このとき、テーパ部材 3 3にはテーパ面 33aが設けられているため、制動片 35はかごガイドレール 4側へも変 位され、押し付けばね 34によりかごガイドレール 4に押し付けられる。この結果、かご ガイドレール 4はその両側力も制動片 35により挟まれ、制動片 35とかごガイドレール 4との間の摩擦力によりかご 2が非常停止される。 When the traveling speed of the force 2 reaches the second overspeed and the pulling bar 38 is pulled up with respect to the car 2 that descends, the braking piece 35 is moved up with respect to the taper member 33. At this time, taper member 3 Since 3 is provided with a tapered surface 33a, the braking piece 35 is also displaced toward the car guide rail 4 and is pressed against the car guide rail 4 by the pressing spring 34. As a result, both side forces of the car guide rail 4 are also sandwiched between the braking pieces 35, and the car 2 is stopped due to the frictional force between the braking piece 35 and the car guide rail 4.
[0019] ガイドシユー収容部 31bの内側には、一対の下部かごガイドシユー (スライディング ガイドシユー） 39が取り付けられ収容されている。下部かごガイドシユー 39は、かごガ イドレール 4を中心に対称に配置されている。かご 2は、上部かごガイドシユー 5及び 下部かごガイドシユー 39がかごガイドレール 4に係合することによって、かごガイドレ ール 4に案内されて昇降路 1内を昇降される。  [0019] A pair of lower car guide shoes (sliding guide shoes) 39 are attached and housed inside the guide shoe housing part 31b. The lower car guide shoe 39 is arranged symmetrically around the car guide rail 4. The car 2 is moved up and down in the hoistway 1 by being guided by the car guide rail 4 when the upper car guide show 5 and the lower car guide show 39 are engaged with the car guide rail 4.
[0020] このようなエレベータ装置を現場に据え付ける場合、前もって工場にぉ 、て、非常 止め本体 32と下部かごガイドシユー 39とが非常止め枠 31内に取り付けられる。この とき、非常止め枠 31の中心力 制動面 35aまでの距離が中心の両側で等しくなるよう に非常止め本体 32が非常止め収容部 31aに取り付けられるとともに、非常止め枠 31 の中心から下部かごガイドシユー 39のガイド面までの距離が中心の両側で等しくなる ようにかごガイドシユー 39がガイドシユー収容部 3 lbに取り付けられる。据付現場で は、かごガイドシユー 39のガイド面とかごガイドレール 4との間の左右隙間だけを調整 しながら非常止め枠 31をかご 2に取り付ければ、制動面 35aとかごガイドレール 4との 間の左右隙間も自動的に同じになる。  When such an elevator apparatus is installed on the site, the emergency stop main body 32 and the lower car guide shoe 39 are installed in the emergency stop frame 31 in advance in the factory. At this time, the emergency stop main body 32 is attached to the emergency stop accommodating portion 31a so that the distance to the center force braking surface 35a of the emergency stop frame 31 is equal on both sides of the center, and at the same time the center of the emergency stop frame 31 and the lower car guide The car guide shoe 39 is mounted in the guide shoe housing 3 lb so that the distance to the guide surface of 39 is equal on both sides of the center. At the installation site, if the emergency stop frame 31 is attached to the car 2 while adjusting only the left and right clearances between the guide surface of the car guide shoe 39 and the car guide rail 4, the distance between the braking surface 35a and the car guide rail 4 The left and right gaps are automatically the same.
[0021] このようなエレベータ装置では、共通の非常止め枠 31に非常止め本体 32とかごガ イドシユー 39とが取り付けられているので、据付現場での位置調整作業を大幅に軽 減することができ、据付作業の効率を向上させることができる。また、下部かごガイド シユー 39と制動片 35とは別部材であるため、下部力ごガイドシユー 39の交換頻度が 高くなることはない。  [0021] In such an elevator apparatus, the emergency stop body 32 and the cage guide 39 are attached to the common emergency stop frame 31, so that the position adjustment work at the installation site can be greatly reduced. The efficiency of installation work can be improved. Further, since the lower car guide shoe 39 and the braking piece 35 are separate members, the replacement force of the lower force guide shoe 39 does not increase.
[0022] なお、上記の例では、下部かごガイドシユー 39としてスライディングガイドシユーを 示したが、かごガイドシュ一は、ローラガイドシユーであってもよい。  In the above example, the sliding guide show is shown as the lower car guide show 39, but the car guide show may be a roller guide show.
また、上記の例では、一対の制動片 35によりかごガイドレール 4を挟む両利きタイプ の非常止め本体 32を示した力 かごガイドレール 4の一方の側面のみに制動片を押 し付ける片利きタイプの非常止め本体を用いてもょ 、。 [0023] さらに、上記の例では、力ご 2の第 2過速度が調速機 11により機械的に検出された ときに非常止め装置 6を動作させる場合を示したが、力ごの過速度を電気的に検出（ 例えばコンピュータによる演算処理により判定)し、非常止め装置を動作させてもよい 。この場合、非常止め本体は、電気的な作動信号の入力に応じて駆動するァクチュ エータ（例えば電磁ァクチユエータ）を有するものであってもよい。 Also, in the above example, a one-handed type that presses the braking piece only on one side of the force-carrying guide rail 4 that shows a double-handed type emergency stop body 32 that sandwiches the car guide rail 4 with a pair of braking pieces 35 Use the emergency stop body. [0023] Furthermore, in the above example, the case where the emergency stop device 6 is operated when the second overspeed of the force 2 is mechanically detected by the governor 11 is shown. May be detected electrically (for example, by a calculation process by a computer) and the emergency stop device may be operated. In this case, the emergency stop main body may have an actuator (for example, an electromagnetic actuator) that is driven in response to an input of an electrical activation signal.
[0024] さらにまた、上記の例では、力ご 2及び釣合おもり 3が 1： 1ロービング方式で吊り下 げられているエレベータ装置を示した力 ロービング方式はこれに限定されず、例え ば 2： 1ロービング方式であってもよ!/、。  [0024] Furthermore, in the above example, the force roving method showing an elevator apparatus in which the force 2 and the counterweight 3 are suspended by the 1: 1 roving method is not limited to this, for example, 2 : 1 roving method!
