Description

エレベータ装置elevator equipment
　本発明は、電動で作動する非常止め装置を備えるエレベータ装置に関する。 The present invention relates to an elevator apparatus equipped with an electrically operated safety device.
　エレベータ装置には、乗りかごの昇降速度を常時監視して、所定の過速状態に陥った乗りかごを非常停止させるために、ガバナおよび非常止め装置が備えられている。一般に、乗りかごとガバナはガバナロープによって結合されており、過速状態を検出すると、ガバナがガバナロープを拘束することで乗りかご側の非常止め装置を動作させ、乗りかごを非常停止するようになっている。 The elevator system is equipped with a governor and an emergency stop device to constantly monitor the ascending and descending speed of the car and to emergency stop the car that has fallen into a predetermined overspeed condition. In general, the car and the governor are connected by a governor rope, and when an overspeed condition is detected, the governor restrains the governor rope and activates the emergency stop device on the car side to bring the car to an emergency stop. there is
　このようなエレベータ装置では、昇降路内に長尺物であるガバナロープを敷設するため、省スペース化および低コスト化が難しい。また、ガバナロープが振れる場合、昇降路内における構造物とガバナロープとが干渉しやすくなる。 In such an elevator system, it is difficult to save space and reduce costs because a long governor rope is laid in the hoistway. In addition, when the governor rope swings, the structures in the hoistway and the governor rope tend to interfere with each other.
　これに対し、ガバナロープを用いず、電動で作動する非常止め装置が提案されている。このような非常止め装置に関する従来技術として、特許文献１に記載された技術が知られている。 On the other hand, a safety device that operates electrically without using a governor rope has been proposed. As a conventional technology related to such a safety device, the technology described in Patent Document 1 is known.
　本従来技術では、乗りかご上に、非常止め装置を駆動する駆動軸と、駆動軸を作動させる作動機構が設けられる。作動機構は、接続片を介して駆動軸に機械的に接続される可動鉄心と、可動鉄心を吸着する電磁石を備えている。駆動軸は、駆動バネによって付勢されているが、通常時は、電磁石が通電され可動鉄心が吸着されているため、作動機構によって駆動軸の動きが拘束されている。 In this prior art, a drive shaft that drives the safety device and an operating mechanism that operates the drive shaft are provided on the car. The operating mechanism includes a movable iron core mechanically connected to the drive shaft via a connecting piece, and an electromagnet that attracts the movable iron core. The drive shaft is biased by a drive spring, but normally the movement of the drive shaft is restrained by the operating mechanism because the electromagnet is energized and the movable iron core is attracted.
　非常時には、電磁石が消磁されて駆動軸の拘束が解かれ、駆動バネの付勢力によって駆動軸が駆動される。これにより、非常止め装置が動作して、乗りかごが非常停止する。 In the event of an emergency, the electromagnet is demagnetized and the restraint on the drive shaft is released, and the drive shaft is driven by the biasing force of the drive spring. As a result, the safety device operates to bring the car to an emergency stop.
　また、非常止め装置を通常状態に復帰させるときには、非常時に移動した可動鉄心に電磁石を移動して近付ける。電磁石が可動鉄心に当接したら、電磁石を通電し、可動鉄心を電磁石に吸着する。さらに、可動鉄心が電磁石に吸着された状態で、電磁石を駆動して、可動鉄心および電磁石を通常時の待機位置に戻す。 Also, when returning the safety device to its normal state, move the electromagnet closer to the movable iron core that was moved in the event of an emergency. When the electromagnet contacts the movable core, the electromagnet is energized and the movable core is attracted to the electromagnet. Further, the electromagnet is driven while the movable iron core is attracted to the electromagnet, and the movable iron core and the electromagnet are returned to the normal standby position.

　上記従来技術では、可動鉄心と接続片とが回動可能に接続される。このため、可動鉄心における電磁石との吸着面の向きが、非常時に可動鉄心が移動すると、変動する。吸着面の向きの変動が大きいと、電磁石と可動鉄心の吸着が不安定となり、非常止め装置の動作の信頼性が低下する恐れがある。 In the conventional technology described above, the movable iron core and the connecting piece are rotatably connected. Therefore, the orientation of the surface of the movable iron core that attracts the electromagnet changes when the movable iron core moves in an emergency. If the orientation of the attracting surface fluctuates significantly, the attraction between the electromagnet and the movable iron core becomes unstable, which may reduce the reliability of the operation of the safety device.

　以下、本発明の一実施形態であるエレベータ装置について、実施例１～２により、図面を用いながら説明する。なお、各図において、参照番号が同一のものは同一の構成要件あるいは類似の機能を備えた構成要件を示している。 Hereinafter, an elevator apparatus that is one embodiment of the present invention will be described with reference to Examples 1 and 2 with reference to the drawings. In each figure, the same reference numbers denote the same components or components with similar functions.
　図１は、本発明の実施例１であるエレベータ装置の概略構成図である。 FIG. 1 is a schematic configuration diagram of an elevator apparatus that is Embodiment 1 of the present invention.
　図１に示すように、エレベータ装置は、乗りかご１と、位置センサ３と、電動作動器１０と、駆動機構（１２～２０）と、引上げロッド２１と、非常止め装置２とを備えている。 As shown in FIG. 1, the elevator system includes a car 1, a position sensor 3, an electric actuator 10, drive mechanisms (12 to 20), a lifting rod 21, and a safety device 2. .
　乗りかご１は、建築物に設けられる昇降路内に主ロープ（図示せず）により吊られており、ガイド装置（図示せず）を介してガイドレール４に摺動可能に係合している。駆動装置（巻上機：図示せず）により主ロープが摩擦駆動されると、乗りかご１は昇降路内を昇降する。 A car 1 is suspended by a main rope (not shown) in a hoistway provided in a building, and is slidably engaged with a guide rail 4 via a guide device (not shown). . When the main rope is friction-driven by a driving device (hoisting machine: not shown), the car 1 ascends and descends in the hoistway.
　位置センサ３は、乗りかご１に備えられ、昇降路内における乗りかご１の位置を検出するとともに、検出された乗りかご１の位置から乗りかご１の昇降速度を常時検出する。したがって、位置センサ３により、乗りかごの昇降速度が所定の過速度を超えたことを検出することができる。 The position sensor 3 is provided in the car 1, detects the position of the car 1 in the hoistway, and constantly detects the ascending/descending speed of the car 1 from the detected position of the car 1. Therefore, the position sensor 3 can detect that the car ascending/descending speed exceeds the predetermined overspeed.
　本実施例１では、位置センサ３は、画像センサを備え、画像センサによって取得されるガイドレール４の表面状態の画像情報に基づいて、乗りかご１の位置および速度を検出する。例えば、予め計測され記憶装置に記憶されるガイドレール４の表面状態の画像情報と、画像センサによって所得される画像情報を照合することにより、乗りかご１の位置が検出される。 In the first embodiment, the position sensor 3 has an image sensor, and detects the position and speed of the car 1 based on the image information of the surface condition of the guide rail 4 acquired by the image sensor. For example, the position of the car 1 is detected by collating the image information of the surface condition of the guide rail 4 measured in advance and stored in the storage device with the image information obtained by the image sensor.
　なお、位置センサとしては、乗りかごに設けられ、乗りかごの移動とともに回転するロータリーエンコーダを用いてもよい。 As the position sensor, a rotary encoder that is provided in the car and rotates as the car moves may be used.
　電動作動器１０は、本実施例では電磁操作器であり、乗りかご１の上部に配置される。電磁操作器は、例えば、ソレノイドもしくは電磁石によって作動する可動片もしくは可動杆を備えるものである。電動作動器１０は、位置センサ３が乗りかご１の所定の過速状態を検出したときに作動する。このとき、操作レバー１１に機械的に接続されている駆動機構（１２～２０）により、引上げロッド２１が引き上げられる。これにより、非常止め装置２が制動状態となる。 The electric actuator 10 is an electromagnetic actuator in this embodiment, and is arranged above the car 1 . The electromagnetic operator has, for example, a movable piece or a movable rod operated by a solenoid or electromagnet. The electric actuator 10 is activated when the position sensor 3 detects a predetermined overspeed condition of the car 1 . At this time, the pulling rod 21 is pulled up by the drive mechanism (12-20) mechanically connected to the operating lever 11. As shown in FIG. As a result, the safety device 2 is brought into a braking state.
　なお、駆動機構（１２～２０）については後述する。 The drive mechanisms (12-20) will be described later.
　非常止め装置２は、乗りかご１の左右に一台ずつ配置される。各非常止め装置２が備える図示しない一対の制動子は、制動位置および非制動位置の間で可動であり、制動位置においてガイドレール４を挟持し、さらに、乗りかご１の下降により相対的に上昇すると、制動子とガイドレール４との間に作用する摩擦力により制動力を生じる。これにより、非常止め装置２は、乗りかご１が過速状態に陥ったときに作動し、乗りかご１を非常停止させる。 The safety devices 2 are arranged one by one on the left and right sides of the car 1. A pair of brakes (not shown) included in each safety device 2 are movable between a braking position and a non-braking position, sandwich the guide rail 4 at the braking position, and rise relatively as the car 1 descends. Then, a braking force is generated by the frictional force acting between the brake shoe and the guide rail 4 . As a result, the safety device 2 is actuated when the car 1 is in an overspeed condition to bring the car 1 to an emergency stop.
　本実施例１のエレベータ装置は、ガバナロープを用いない、いわゆるロープレスガバナシステムを備えるものであり、乗りかご１の昇降速度が定格速度を超えて第１過速度（例えば、定格速度の１．３倍を超えない速度）に達すると、駆動装置（巻上機）の電源およびこの駆動装置を制御する制御装置の電源が遮断される。また、乗りかご１の下降速度が第２過速度（例えば、定格速度の１．４倍を超えない速度）に達すると、乗りかご１に設けられる電動作動器１０が電気的に作動される。これにより、非常止め装置２が動作して、乗りかご１が非常停止される。 The elevator system of the present embodiment 1 is provided with a so-called ropeless governor system that does not use a governor rope. speed not more than doubled), power to the drive (hoisting machine) and to the control device controlling this drive is cut off. Also, when the descending speed of the car 1 reaches a second overspeed (for example, a speed not exceeding 1.4 times the rated speed), the electric actuator 10 provided on the car 1 is electrically actuated. As a result, the safety device 2 is operated and the car 1 is brought to an emergency stop.
　本実施例において、ロープレスガバナシステムは、前述の位置センサ３と、位置センサ３の出力信号に基づいて、乗りかご１の過速状態を判定する安全制御装置とから構成される。この安全制御装置は、位置センサ３の出力信号に基づいて乗りかご１の速度を計測し、計測される速度が第１過速度に達したと判定すると、駆動装置（巻上機）の電源およびこの駆動装置を制御する制御装置の電源を遮断するための指令信号を出力する。また、安全制御装置は、計測される速度が第２過速度に達したと判定すると、電動作動器１０を作動するための指令信号を出力する。 In this embodiment, the ropeless governor system is composed of the position sensor 3 described above and a safety control device that determines the overspeed condition of the car 1 based on the output signal of the position sensor 3 . This safety control device measures the speed of the car 1 based on the output signal of the position sensor 3, and when it is determined that the measured speed has reached the first overspeed, the power supply of the drive device (hoisting machine) and It outputs a command signal for shutting off the power supply of the control device that controls this drive device. Further, when the safety control device determines that the measured speed has reached the second overspeed, it outputs a command signal for operating the electric actuator 10 .
　前述のように、非常止め装置２が備える一対の制動子が引上げロッド２１によって引き上げられると、一対の制動子がガイドレール４を挟持する。引上げロッド２１は、電動作動器１０に機械的に接続される駆動機構（１２～２０）によって駆動される。 As described above, when the pair of brakes included in the safety device 2 are pulled up by the lifting rod 21, the pair of brakes sandwich the guide rail 4. The lifting rod 21 is driven by a drive mechanism (12-20) mechanically connected to the electric actuator 10. As shown in FIG.
　以下、この駆動機構の構成について説明する。 The configuration of this drive mechanism will be described below.
　電動作動器１０の操作レバー１１と第１の作動片１６が連結され、略Ｔ字状の第１リンク部材が構成される。操作レバー１１および第１の作動片１６はそれぞれＴ字の頭部および足部を構成する。略Ｔ字状の第１リンク部材は、操作レバー１１と第１の作動片１６の連結部において、第１の作動軸１９を介してクロスヘッド５０に回動可能に支持される。Ｔ字の足部となる作動片１６における操作レバー１１と作動片１６の連結部とは反対側の端部に、一対の引上げロッド２１の一方（図中左側）の端部が接続される。 The operating lever 11 of the electric actuator 10 and the first operating piece 16 are connected to form a substantially T-shaped first link member. The operating lever 11 and the first operating piece 16 constitute a T-shaped head and foot, respectively. The substantially T-shaped first link member is rotatably supported by the crosshead 50 via the first operating shaft 19 at the connecting portion between the operating lever 11 and the first operating piece 16 . One (left side in the figure) end of a pair of lifting rods 21 is connected to the end of the operating piece 16 which is the foot of the T-shape, opposite to the connecting portion between the operating lever 11 and the operating piece 16 .
　なお、電動作動器１０が備える補助リンク部材９１が、回動軸９２を介して、クロスヘッド５０に回動可能に支持される。補助リンク部材９１については、後述する（図２）。 An auxiliary link member 91 included in the electric actuator 10 is rotatably supported by the crosshead 50 via a rotation shaft 92 . The auxiliary link member 91 will be described later (Fig. 2).
　接続片１７と第２の作動片１８が連結され、略Ｔ字状の第２リンク部材が構成される。接続片１７および第２の作動片１８はそれぞれＴ字の頭部および足部を構成する。略Ｔ字状の第２リンク部材は、接続片１７と第２の作動片１８の連結部において、第２の作動軸２０を介してクロスヘッド５０に回動可能に支持される。Ｔ字の足部となる第２の作動片１８における接続片１７と第２の作動片１８の連結部とは反対側の端部に、一対の引上げロッド２１の他方（図中右側）の端部が接続される。 The connecting piece 17 and the second operating piece 18 are connected to form a substantially T-shaped second link member. The connecting piece 17 and the second operating piece 18 constitute a T-shaped head and foot, respectively. The substantially T-shaped second link member is rotatably supported by the crosshead 50 via the second operating shaft 20 at the connecting portion between the connecting piece 17 and the second operating piece 18 . The other end (right side in the figure) of the pair of lifting rods 21 is attached to the end of the second operating piece 18, which is the foot of the T-shape, opposite to the connecting portion between the connecting piece 17 and the second operating piece 18. are connected.
　筐体３０の内部から外部に伸びる操作レバー１１の端部と、接続片１７の両端部の内、第２の作動軸２０よりも乗りかご１の上部に近い端部とが、それぞれ、乗りかご１上に横たわる駆動軸１２の一端（図中左側）と他端（図中右側）とに接続される。駆動軸１２は、クロスヘッド５０に固定される固定部１４を摺動可能に貫通している。また、駆動軸１２は、押圧部材１５を貫通し、押圧部材は駆動軸１２に固定されている。なお、押圧部材１５は、固定部１４の第２リンク部材（接続片１７、第２の作動片１８）側に位置する。固定部１４と押圧部材１５の間に、弾性体である駆動バネ１３が位置し、駆動バネ１３には駆動軸１２が挿通される。 The end of the operating lever 11 extending from the inside of the housing 30 to the outside and the end of the connecting piece 17 nearer to the upper part of the car 1 than the second operating shaft 20 are connected to the car. 1 are connected to one end (left side in the figure) and the other end (right side in the figure) of a drive shaft 12 lying on the upper side. The drive shaft 12 slidably penetrates a fixed portion 14 fixed to the crosshead 50 . Further, the drive shaft 12 passes through the pressing member 15 , and the pressing member is fixed to the drive shaft 12 . The pressing member 15 is positioned on the second link member (connecting piece 17, second operating piece 18) side of the fixed portion 14. As shown in FIG. An elastic drive spring 13 is positioned between the fixed portion 14 and the pressing member 15 , and the drive shaft 12 is inserted through the drive spring 13 .
　なお、筐体３０は、防塵用であり、後述する電動作動器１０の機構部における塵埃の付着を防止する。操作レバー１１および補助リンク部材９１は、筐体３０内において、電動作動器１０の機構部に機械的に接続される。また、操作レバー１１および補助リンク部材９１は、筐体３０の上面における開口部を通って、筐体３０外部に延びている。 It should be noted that the housing 30 is for dust prevention, and prevents dust from adhering to the mechanical portion of the electric actuator 10, which will be described later. The operating lever 11 and the auxiliary link member 91 are mechanically connected to the mechanical portion of the electric actuator 10 inside the housing 30 . Also, the operating lever 11 and the auxiliary link member 91 extend outside the housing 30 through an opening in the upper surface of the housing 30 .
　電動作動器１０が作動すると、すなわち本実施例１では電磁石への通電が遮断されると、駆動バネ１３の付勢力に抗して操作レバー１１の動きを拘束する電磁力が消失するので、押圧部材１５に加わる駆動バネ１３の付勢力によって、駆動軸１２が長手方向に沿って駆動される。このため、第１リンク部材（操作レバー１１、第１の作動片１６）が第１の作動軸１９の回りに回動するとともに、第２リンク部材（接続片１７、第２の作動片１８）が第２の作動軸２０の回りに回動する。これにより、第１リンク部材の第１の作動片１６に接続される一方の引上げロッド２１が駆動されて引き上げられるとともに、第２リンク部材の第２の作動片１８に接続される他方の引上げロッド２１が駆動されて引き上げられる。 When the electric actuator 10 operates, that is, when the electromagnet is de-energized in the first embodiment, the electromagnetic force restraining the movement of the operating lever 11 against the biasing force of the drive spring 13 disappears. The biasing force of the drive spring 13 applied to the member 15 drives the drive shaft 12 along the longitudinal direction. Therefore, the first link member (operating lever 11, first operating piece 16) rotates around the first operating shaft 19, and the second link member (connecting piece 17, second operating piece 18) rotates. rotates about the second actuation axis 20 . As a result, one lifting rod 21 connected to the first operating piece 16 of the first link member is driven and lifted, and the other lifting rod connected to the second operating piece 18 of the second link member is pulled up. 21 is driven and pulled up.
　図２は、本実施例１における電動作動器１０の機構部を示し、図１の設置状態における正面図である。また、図３は、本実施例１における電動作動器１０の機構部を示し、図１の設置状態における平面図である。ただし、図３では、筐体３０については、図示が省略されている。なお、図２および図３において、非常止め装置は制動状態であり、電動作動器１０は作動状態である。すなわち、エレベータ装置は、停止状態である。 FIG. 2 shows the mechanical portion of the electric actuator 10 according to the first embodiment, and is a front view in the installation state of FIG. 3 is a plan view showing the mechanical portion of the electric actuator 10 according to the first embodiment, in the installation state of FIG. 1. As shown in FIG. However, in FIG. 3, illustration of the housing 30 is omitted. 2 and 3, the safety device is in a braking state, and the electric actuator 10 is in an operating state. That is, the elevator installation is in a stopped state.
　エレベータ装置が通常運転されているとき、電動作動器１０は、待機状態にある。図２中の二点鎖線が示すように、待機状態（図６参照）においては、操作レバー１１に接続される可動部材３４が、磁極面が可動部材３４に対向し、コイルが通電されて励磁されている電磁石３５に、電磁力によって吸着されている。なお、待機状態では、電磁石３５は、図２に示す電磁石３５の位置で、可動部材３４を吸着している。これにより、駆動バネ１３（圧縮バネ）の付勢力に抗して、操作レバー１１の動きが拘束されている。 The electric actuator 10 is in a standby state when the elevator system is in normal operation. 2, in the standby state (see FIG. 6), the magnetic pole surface of the movable member 34 connected to the operating lever 11 faces the movable member 34, and the coil is energized and excited. It is attracted by an electromagnetic force to the electromagnet 35 that is attached. In the standby state, the electromagnet 35 attracts the movable member 34 at the position of the electromagnet 35 shown in FIG. As a result, the movement of the operating lever 11 is restrained against the biasing force of the drive spring 13 (compression spring).
　本実施例１において、可動部材３４は、磁性体からなる。磁性体として、好ましくは、低炭素鋼やパーマロイ（鉄・ニッケル合金）などの軟磁性体が適用される。なお、可動部材３４おいて、少なくとも電磁石３５と吸着する部分が磁性体であればよい。 　In the first embodiment, the movable member 34 is made of a magnetic material. As the magnetic material, a soft magnetic material such as low carbon steel or permalloy (iron-nickel alloy) is preferably applied. At least the portion of the movable member 34 that attracts the electromagnet 35 may be made of a magnetic material.
　操作レバー１１は、可動部材３４に設けられる接続部材である接続ブラケット３８に接続される。接続ブラケット３８は、可動部材３４における電磁石３５との吸着面の裏面に固定される。接続ブラケット３８は、この裏面から垂直方向に延在している。接続ブラケット３８の延在部の中央部には、長孔９４が設けられる。操作レバー１１の一端部は、長孔９４を通る係合ピン９５を介して、接続ブラケット３８に回動可能に接続される。長孔９４の長手方向は、可動部材３４の前述の裏面に平行な方向である。長孔９４の長手方向に沿って、係合ピン９５は摺動可能であり、係合ピン９５とともに操作レバー１１も移動可能である。 The operation lever 11 is connected to a connection bracket 38 which is a connection member provided on the movable member 34 . The connection bracket 38 is fixed to the back surface of the electromagnet 35 attraction surface of the movable member 34 . A connecting bracket 38 extends vertically from this back surface. A long hole 94 is provided in the central portion of the extending portion of the connection bracket 38 . One end of the operating lever 11 is rotatably connected to the connection bracket 38 via an engagement pin 95 passing through a long hole 94 . The longitudinal direction of the long hole 94 is parallel to the back surface of the movable member 34 . The engaging pin 95 is slidable along the longitudinal direction of the elongated hole 94 , and the operating lever 11 is also movable together with the engaging pin 95 .
　図３に示すように、本実施例１において、接続ブラケット３８は、可動部材３４の前述の裏面から垂直方向に延び、かつ互いに平行に配置されている二つの延在部を有する。これに二つの延在部に設けられる各長孔９４が、互いに対向するように設けられる。これらの長孔９４に、係合ピン９５が通る。二つの延在部の各々の両端部の内、可動部材３４と反対側の端部には、錘１０１が設けられる。なお、本実施例１では、板状の錘１０１の平面部と、延在部の平面部とが接合される。 As shown in FIG. 3, in the first embodiment, the connection bracket 38 has two extensions extending vertically from the back surface of the movable member 34 and arranged parallel to each other. The elongated holes 94 provided in the two extending portions are provided so as to face each other. Engagement pins 95 pass through these elongated holes 94 . A weight 101 is provided at the end opposite to the movable member 34 among the ends of each of the two extensions. In addition, in the present Example 1, the plane part of the plate-shaped weight 101 and the plane part of the extension part are joined.
　接続ブラケット３８には、錘１０１によって、係合ピン９５を支点として、可動部材３４による力のモーメントとは逆方向の力のモーメントが作用する。このため、可動部材３４における電磁石３５との吸着面の方向が、電磁石３５の磁極面の方向に近くなる。これにより、電磁石３５を移動して、励磁された電磁石３５が可動部材３４を吸着するときに、可動部材３４が電磁石３５に安定に吸着される。なお、吸着面および磁極面の各方向は、各面の法線方向とする。 A moment of force in the opposite direction to the moment of force by the movable member 34 is applied to the connection bracket 38 by the weight 101 with the engaging pin 95 as a fulcrum. Therefore, the direction of the attracting surface of the movable member 34 with respect to the electromagnet 35 becomes close to the direction of the magnetic pole surface of the electromagnet 35 . As a result, when the electromagnet 35 is moved and the excited electromagnet 35 attracts the movable member 34 , the movable member 34 is stably attracted to the electromagnet 35 . Each direction of the attracting surface and the magnetic pole surface shall be the normal direction of each surface.
　好ましくは、錘１０１の重量は、錘１０１による力のモーメントと可動部材３４による力のモーメントとが釣り合うように設定される。 Preferably, the weight of the weight 101 is set so that the moment of force by the weight 101 and the moment of force by the movable member 34 are balanced.
　図２に示すように、電動作動器１０は、補助リンク部材９１を有している。補助リンク部材９１の長手方向の一端部は、回動軸９２を介してクロスヘッド５０に回動可能に支持される。回動軸９２は、第１の作動軸１９に隣接して配置される。補助リンク部材９１の長手方向の他端部は、接続ブラケット３８において長孔９４に隣接する、長孔９４と同様の長孔９６を通る係合ピン９７を介して、接続ブラケット３８に回動可能に接続される。このため、補助リンク部材９１は、その長手方向が操作レバー１１の長手方向と平行になるように、操作レバー１１に隣接して配置される。 As shown in FIG. 2, the electric actuator 10 has an auxiliary link member 91. One longitudinal end of the auxiliary link member 91 is rotatably supported by the crosshead 50 via a rotation shaft 92 . The pivot shaft 92 is arranged adjacent to the first actuation shaft 19 . The other longitudinal end of the auxiliary link member 91 is rotatable to the connecting bracket 38 via an engaging pin 97 passing through an elongated hole 96 similar to the elongated hole 94 adjacent to the elongated hole 94 in the connecting bracket 38 . connected to Therefore, the auxiliary link member 91 is arranged adjacent to the operating lever 11 so that its longitudinal direction is parallel to the longitudinal direction of the operating lever 11 .
　補助リンク部材９１により、非常止め装置２の動作時に、消磁された電磁石３５から離れた場合でも、接続ブラケット３８および可動部材３４の姿勢が大きく変化することを抑制できる。これにより、接続ブラケット３８および可動部材３４が、電動作動器１０の基板部４０やクロスヘッド５０に干渉することが防止される。また、補助リンク部材９１により、電磁石３５を移動して、励磁された電磁石３５が可動部材３４を吸着するときに、錘１０１とあいまって、可動部材３４が電磁石３５に、確実に、安定に吸着される。 Due to the auxiliary link member 91, even when the safety device 2 moves away from the demagnetized electromagnet 35, it is possible to prevent the attitudes of the connection bracket 38 and the movable member 34 from significantly changing. This prevents the connection bracket 38 and the movable member 34 from interfering with the substrate portion 40 and the crosshead 50 of the electric actuator 10 . Further, when the electromagnet 35 is moved by the auxiliary link member 91 and the excited electromagnet 35 attracts the movable member 34, the movable member 34 is reliably and stably attracted to the electromagnet 35 in combination with the weight 101. be done.
　なお、電動作動器１０が補助リンク部材９１を備えない場合でも、錘１０１により、接続ブラケット３８および可動部材３４の姿勢が大きく変化することを抑制できる。 Even if the electric actuator 10 does not include the auxiliary link member 91, the weight 101 can prevent the attitudes of the connection bracket 38 and the movable member 34 from significantly changing.
　次に、図２に示すような、電動作動器１０の作動状態について説明する。 Next, the operating state of the electric actuator 10 as shown in FIG. 2 will be described.
　図示しない安全制御装置からの指令により、電磁石３５の励磁が停止されると、可動部材３４に作用する電磁力が消失する。これにより、可動部材３４が電磁石３５に吸着されることによる操作レバー１１の拘束が解けるので、駆動バネ１３の付勢力によって駆動軸１２が駆動される。 When the excitation of the electromagnet 35 is stopped by a command from a safety control device (not shown), the electromagnetic force acting on the movable member 34 disappears. As a result, the operation lever 11 is released from the restraint caused by the movable member 34 being attracted to the electromagnet 35 , and the drive shaft 12 is driven by the biasing force of the drive spring 13 .
　駆動軸１２が駆動されると、駆動軸１２に接続される第１リンク部材、すなわち操作レバー１１および第１の作動片が第１の作動軸１９の回りに回動する。これにより、第１の作動片１６に接続される引上げロッド２１が引き上げられる。 When the drive shaft 12 is driven, the first link member connected to the drive shaft 12, that is, the operating lever 11 and the first operating piece rotate around the first operating shaft 19. Thereby, the pulling rod 21 connected to the first operating piece 16 is pulled up.
　上述のように操作レバー１１が回動すると、操作レバー１１に接続される可動部材３４は、操作レバー１１の回動方向に沿って、図２において二点鎖線で示す位置から、図２に示す可動部材３４の位置まで移動する。 When the operating lever 11 rotates as described above, the movable member 34 connected to the operating lever 11 moves along the rotating direction of the operating lever 11 from the position indicated by the two-dot chain line in FIG. It moves to the position of the movable member 34 .
　電動作動器１０を、待機状態に復帰させるためには、次に述べるように、電動作動器１０の機構部（３６，３７，４０～４２）によって、可動部材３４を移動位置（図２）から待機時の位置（図２中の二点鎖線）に戻す。 In order to return the electric actuator 10 to the standby state, as described below, the movable member 34 is moved from the moving position (FIG. 2) by the mechanical portions (36, 37, 40 to 42) of the electric actuator 10. Return to the standby position (two-dot chain line in FIG. 2).
　図２，３に示すように、電動作動器１０は、可動部材３４を駆動するために基板部４０の水平な平面部上に位置する送りねじ３６を有する。送りねじ３６は、基板部４０の平面上に固定される第１の支持部材４１および第２の支持部材４２によって回転可能に支持される。電磁石３５はコアプレート４９における可動部材３４側に固定される。コアプレート４９において、電磁石３５が固定される側とは反対側には、送りナット３９が固定される。送りナット３９は送りねじ３６と螺合する。送りねじ３６は、モータ３７によって回転される。 As shown in FIGS. 2 and 3, the electric actuator 10 has a feed screw 36 positioned on the horizontal plane portion of the base plate portion 40 to drive the movable member 34 . The feed screw 36 is rotatably supported by a first support member 41 and a second support member 42 fixed on the plane of the substrate portion 40 . The electromagnet 35 is fixed to the movable member 34 side of the core plate 49 . A feed nut 39 is fixed to the side of the core plate 49 opposite to the side to which the electromagnet 35 is fixed. A feed nut 39 is screwed onto the feed screw 36 . Feed screw 36 is rotated by motor 37 .
　基板部４０は、乗りかご１上もしくはクロスヘッド５０における水平な平面部上に載置されて固定される。したがって、電動作動器１０の機構部は、乗りかご１上もしくはクロスヘッド５０の水平な平面部上に位置する。なお、基板部４０は、乗りかご１上もしくはクロスヘッド５０における水平な平面部から構成されてもよい。 The substrate portion 40 is placed and fixed on the car 1 or on the horizontal plane portion of the crosshead 50 . Therefore, the mechanical portion of the electric actuator 10 is positioned on the car 1 or on the horizontal plane portion of the crosshead 50 . In addition, the substrate portion 40 may be configured from a horizontal plane portion on the car 1 or on the crosshead 50 .
　電動作動器１０を待機状態に復帰させるには、まず、電磁石３５を励磁しながら、モータ３７を駆動して送りねじを回転させる。回転する送りねじ３６と、コアプレート４９を介して電磁石３５に設けられる送りナット３９とによって、モータ３７の回転が、送りねじ３６の軸方向に沿った電磁石３５の直線的移動に変換される。これにより、電磁石３５は、図２に示す可動部材３４の移動位置に近づき、可動部材３４は、電磁石３５による電磁力が作用して、電磁石３５に吸着する。なお、電磁石３５は、励磁せずに移動させ、可動部材３４に当接したら励磁するようにしてもよい。 To return the electric actuator 10 to the standby state, first, while exciting the electromagnet 35, the motor 37 is driven to rotate the feed screw. Rotation of the motor 37 is converted into linear movement of the electromagnet 35 along the axial direction of the feed screw 36 by the rotating feed screw 36 and the feed nut 39 provided on the electromagnet 35 via the core plate 49 . As a result, the electromagnet 35 approaches the moving position of the movable member 34 shown in FIG. Alternatively, the electromagnet 35 may be moved without being energized, and energized when it comes into contact with the movable member 34 .
　可動部材３４が電磁石３５に吸着したら、電磁石３５の励磁を継続しながら、モータ３７の回転方向を逆にして、送りねじ３６を逆転させる。これにより、可動部材３４は、電磁石３５とともに、待機時の位置まで移動する。 When the movable member 34 is attracted to the electromagnet 35, the direction of rotation of the motor 37 is reversed while the excitation of the electromagnet 35 is continued, and the feed screw 36 is reversed. As a result, the movable member 34 moves together with the electromagnet 35 to the standby position.
　電動作動器１０の基板部４０上には、待機状態における電磁石３５の下方に、弾性体である板バネからなる補助保持部５６が設けられる。補助保持部５６は、コアプレート４９または送りナット３９に当接する。なお、図２では、補助保持部５６は、コアプレート４９に当接する。補助保持部５６は、コアプレート４９および送りナット３９を、送りねじ３６に向けて付勢する。これにより、乗りかご１（図１）の動作時に生じる振動によって、送りナット３９が移動することが防止される。 On the substrate portion 40 of the electric actuator 10, an auxiliary holding portion 56 made of an elastic plate spring is provided below the electromagnet 35 in the standby state. The auxiliary holding portion 56 contacts the core plate 49 or the feed nut 39 . In addition, in FIG. 2 , the auxiliary holding portion 56 abuts on the core plate 49 . Auxiliary holding portion 56 biases core plate 49 and feed nut 39 toward feed screw 36 . This prevents the feed nut 39 from moving due to vibrations that occur during operation of the car 1 (FIG. 1).
　図４は、比較例であるエレベータ装置における電動作動器の機構部を示す。 　Fig. 4 shows a mechanical part of an electric actuator in an elevator system as a comparative example.
　本比較例では、接続ブラケット３８が錘１０１（図２，３）を備えていない。 In this comparative example, the connection bracket 38 does not have the weight 101 (FIGS. 2 and 3).
　本比較例では、可動部材３４が、非常止め装置２の動作時に、待機時の位置（図２の二点鎖線）から図４の位置まで移動すると、図４に示すように、送りねじ３６の長手方向に対して大きく傾く。このため、電磁石３５を移動させて、電磁石３５に可動部材３４を吸着させるとき、電磁石３５と可動部材３４との吸着状態が不安定になる。さらに、電磁石３５と可動部材３４とが互いに局所的に当接するため、可動部材３４もしくは電磁石３５が損傷する恐れがある。 In this comparative example, when the movable member 34 moves from the standby position (two-dot chain line in FIG. 2) to the position shown in FIG. Large inclination with respect to the longitudinal direction. Therefore, when the electromagnet 35 is moved to attract the movable member 34 to the electromagnet 35, the attraction state between the electromagnet 35 and the movable member 34 becomes unstable. Furthermore, since the electromagnet 35 and the movable member 34 locally contact each other, the movable member 34 or the electromagnet 35 may be damaged.
　これに対し、本実施例１では、錘１０１によって可動部材３４の傾きが抑制されるので、電磁石３５と可動部材３４とが安定に吸着される。さらに、電磁石３５と可動部材３４の損傷が防止される。 On the other hand, in the first embodiment, tilting of the movable member 34 is suppressed by the weight 101, so that the electromagnet 35 and the movable member 34 are stably attracted. Furthermore, damage to the electromagnet 35 and the movable member 34 is prevented.
　上述のように、実施例１によれば、可動部材３４の傾きを抑制する部材として、可動部材３４と操作レバー１１とを接続する接続ブラケット３８に錘１０１を設けることにより、可動部材３４と電磁石３５との吸着の安定性が向上する。これにより、電動作動器１０の動作の信頼性が向上するので、非常止め装置２の動作の信頼性が向上する。 As described above, according to the first embodiment, the connection bracket 38 connecting the movable member 34 and the operation lever 11 is provided with the weight 101 as a member for suppressing the inclination of the movable member 34, whereby the movable member 34 and the electromagnet The stability of adsorption with 35 is improved. As a result, the reliability of the operation of the electric actuator 10 is improved, so the reliability of the operation of the safety device 2 is improved.
　なお、本実施例１によれば、乗りかご１の過速状態を検知した時に限らず、停電時においても、同様に、電動作動器１０の動作の信頼性が向上する。 It should be noted that according to the first embodiment, the reliability of the operation of the electric actuator 10 is improved not only when the overspeed state of the car 1 is detected, but also at the time of power failure.
　次に、本発明の実施例２であるエレベータ装置について説明する。なお、本実施例２の概略構成は、実施例１（図１）と同様である。 Next, an elevator system, which is Embodiment 2 of the present invention, will be described. The schematic configuration of the second embodiment is the same as that of the first embodiment (FIG. 1).
　図５は、本実施例２における電動作動器１０の機構部を示し、図１の設置状態における正面図である。また、図６は、本実施例２における電動作動器１０の機構部を示し、図１の設置状態における平面図である。ただし、図６では、筐体３０については、図示が省略されている。なお、図５および図６において、非常止め装置は制動状態であり、電動作動器１０は作動状態である。すなわち、エレベータ装置は、停止状態である。 FIG. 5 shows the mechanical portion of the electric actuator 10 in the second embodiment, and is a front view in the installation state of FIG. 6 is a plan view showing the mechanical portion of the electric actuator 10 in the second embodiment, in the installation state of FIG. 1. As shown in FIG. However, in FIG. 6, illustration of the housing 30 is omitted. 5 and 6, the safety device is in the braking state, and the electric actuator 10 is in the operating state. That is, the elevator installation is in a stopped state.
　以下、主に、実施例１と異なる点について説明する。 The points that differ from the first embodiment will be mainly described below.
　本実施例２では、電動作動器１０は、可動部材３４における電磁石３５との吸着面の方向が、電磁石の磁極面の方向から傾くことを抑制する部材として、接続ブラケット３８の移動を制限するストッパ部材１１１を備えている。 In the second embodiment, the electric actuator 10 includes a stopper that restricts the movement of the connection bracket 38 as a member that suppresses inclination of the direction of the attracting surface of the movable member 34 to the electromagnet 35 from the direction of the magnetic pole surface of the electromagnet. A member 111 is provided.
　ストッパ部材１１１は、基板部４０上において、接続ブラケット３８の可動部材３４からの延在部の自由端部に対向する位置に固定的されるストッパ支持部材１１２に設けられる。 The stopper member 111 is provided on a stopper support member 112 that is fixed on the base plate 40 at a position facing the free end of the extension of the connecting bracket 38 from the movable member 34 .
　非常止め装置２の動作時に操作レバー１１が作動軸１９の回りに回動することに伴って可動部材３４および接続ブラケット３８が移動すると、接続ブラケット３８の延在部の自由端部がストッパ部材１１１に当接する。これにより、送りねじ３６の長手方向における可動部材３４および接続ブラケット３８の移動量が制限される。これにより、可動部材３４の傾きが抑制される。 When the movable member 34 and the connecting bracket 38 move as the operating lever 11 rotates around the operating shaft 19 during operation of the safety device 2 , the free end of the extending portion of the connecting bracket 38 moves toward the stopper member 111 . abut. This limits the amount of movement of the movable member 34 and the connection bracket 38 in the longitudinal direction of the feed screw 36 . As a result, tilting of the movable member 34 is suppressed.
　また、ストッパ部材１１１は、接続ブラケット３８の延在部の自由端部において、長孔９４の長手方向に沿って係合ピン９５から離れた位置、本実施例２では係合ピン９５の下方の位置において、接続ブラケット３８の延在部の自由端部に当接する。 The stopper member 111 is located at the free end of the extending portion of the connection bracket 38 at a position away from the engaging pin 95 along the longitudinal direction of the elongated hole 94, which is below the engaging pin 95 in the second embodiment. In position, it abuts the free end of the extension of the connecting bracket 38 .
　これにより、接続ブラケット３８には、係合ピン９５を支点として、可動部材３４による力のモーメントとは逆方向に、接続ブラケット３８の延在部の自由端部がストッパ部材１１１から受ける反力による力のモーメントが作用する。このため、可動部材３４における電磁石３５との吸着面の方向が、電磁石３５の磁極面の方向に近くなる。すなわち、可動部材３４の傾きが抑制される。これにより、電磁石３５を移動して、励磁された電磁石３５が可動部材３４を吸着するときに、可動部材３４が電磁石３５に安定に吸着される。 As a result, the connecting bracket 38 receives a reaction force from the stopper member 111 at the free end of the extending portion of the connecting bracket 38 in a direction opposite to the moment of force generated by the movable member 34 with the engaging pin 95 as a fulcrum. A moment of force acts. Therefore, the direction of the attracting surface of the movable member 34 with respect to the electromagnet 35 becomes close to the direction of the magnetic pole surface of the electromagnet 35 . That is, tilting of the movable member 34 is suppressed. As a result, when the electromagnet 35 is moved and the excited electromagnet 35 attracts the movable member 34 , the movable member 34 is stably attracted to the electromagnet 35 .
　なお、ストッパ部材１１１としては、例えば、ボルトが適用される。この場合、ボルト軸の先端が接続ブラケット３８に当接する。また、ストッパ支持部材にボルトと螺合するねじ部を設けることにより、接続ブラケット３８の移動を制限する位置を調整可能となる。これにより、確実に、可動部材３４の傾きが抑制できる。 A bolt, for example, is applied as the stopper member 111 . In this case, the tip of the bolt shaft contacts the connection bracket 38 . Further, by providing the stopper supporting member with a threaded portion to be screwed with the bolt, it becomes possible to adjust the position at which the movement of the connection bracket 38 is restricted. As a result, tilting of the movable member 34 can be reliably suppressed.
　上述のように、実施例２によれば、可動部材３４の傾きを抑制する部材として、可動部材３４および接続ブラケット３８の移動量を制限するストッパ部材を設けることにより、可動部材３４と電磁石３５との吸着の安定性が向上する。これにより、電動作動器１０の動作の信頼性が向上するので、非常止め装置２の動作の信頼性が向上する。 As described above, according to the second embodiment, as a member for suppressing inclination of the movable member 34, the stopper member for limiting the amount of movement of the movable member 34 and the connection bracket 38 is provided. adsorption stability is improved. As a result, the reliability of the operation of the electric actuator 10 is improved, so the reliability of the operation of the safety device 2 is improved.
　本実施例２によれば、実施例１と同様に、乗りかごの過速状態を検知した時に限らず、停電時においても、電動作動器１０の動作の信頼性が向上する。 According to the second embodiment, as in the first embodiment, the reliability of the operation of the electric actuator 10 is improved not only when the overspeed state of the car is detected, but also during a power failure.
　なお、本発明は前述した実施例に限定されるものではなく、様々な変形例が含まれる。例えば、前述した実施例は本発明を分かりやすく説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定されるものではない。また、実施例の構成の一部について、他の構成の追加・削除・置き換えをすることが可能である。 It should be noted that the present invention is not limited to the above-described embodiments, and includes various modifications.
