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を備える駆動機構と、駆動軸を作動させる作動機構が設けられる。作動機構は、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 mechanism having 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 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.

　そこで、本発明は、電動で作動しながらも、動作音を低減できる非常止め装置を備えるエレベータ装置を提供する。 Therefore, the present invention provides an elevator apparatus equipped with a safety device capable of reducing operating noise while operating electrically.
　上記課題を解決するために、本発明によるエレベータ装置は、乗りかごと、乗りかごに設けられる非常止め装置と、乗りかごに設けられ、非常止め装置を駆動する駆動機構と、駆動機構を作動させる電動作動器と、を備えるものであって、駆動機構および電動作動器と乗りかごとの間に、防振部を備える。 In order to solve the above problems, an elevator apparatus according to the present invention includes a car, a safety device provided in the car, a drive mechanism provided in the car for driving the safety device, and a drive mechanism for operating the safety device. and an electric actuator, comprising a vibration isolator between the drive mechanism and the electric actuator and the car.
　本発明によれば、駆動機構および電動作動器に発生する機械的振動による動作音を抑制することができる。 According to the present invention, it is possible to suppress operating noise caused by mechanical vibrations generated in the drive mechanism and the electric actuator.

　図１は、本発明の実施例１であるエレベータ装置の概略全体構成図である。 FIG. 1 is a schematic overall configuration diagram of an elevator apparatus that is Embodiment 1 of the present invention.
　本エレベータ装置は、昇降路１００上に設けられる機械室２００内に巻上機を有し、巻上機におけるトラクションシーブ７とトラクションシーブ７に並設される方向転換プーリ８とに巻き掛けられる主ロープ６の一端部に乗りかご１が連結され、主ロープ６の他端部に釣り合いおもり３が連結されている。 The present elevator apparatus has a hoisting machine in a machine room 200 provided on a hoistway 100, and a traction sheave 7 in the hoisting machine and a direction changing pulley 8 arranged in parallel with the traction sheave 7 are mainly wound on. The car 1 is connected to one end of the rope 6 , and the counterweight 3 is connected to the other end of the main rope 6 .
　乗りかご１および釣り合いおもり３は、昇降路１００内において、主ロープ６によって吊られる。電動機によって巻上機が駆動されてトラクションシーブ７が回転すると、主ロープ６が駆動される。これにより、乗りかご１および釣り合いおもり３は、昇降路１００内を互いに反対方向に昇降する。 The car 1 and the counterweight 3 are suspended by the main rope 6 inside the hoistway 100 . When the hoist is driven by the electric motor to rotate the traction sheave 7, the main rope 6 is driven. As a result, the car 1 and the counterweight 3 move up and down in the hoistway 100 in opposite directions.
　乗りかご１の下部には一対のかご用ガイド装置９ａが設けられる。各かご用ガイド装置９ａは、対向するかご用ガイドレール４ａに摺動可能に係合する。このため、乗りかご１は、一対のかご用ガイドレール４ａに案内されながら、一対のかご用ガイドレール４ａに沿って昇降路１００内を昇降する。 A pair of car guide devices 9a are provided at the bottom of the car 1. Each car guide device 9a is slidably engaged with the opposing car guide rail 4a. Therefore, the car 1 ascends and descends in the hoistway 100 along the pair of car guide rails 4a while being guided by the pair of car guide rails 4a.
　釣り合いおもり３の下部には一対のおもり用ガイド装置９ｂが設けられる。各おもり用ガイド装置９ｂは、対向するおもり用ガイドレール４ｂに摺動可能に係合する。このため、釣り合いおもり３は、一対のおもり用ガイドレール４ｂに案内されながら、一対のおもり用ガイドレール４ｂに沿って昇降路１００内を昇降する。 A pair of weight guide devices 9b are provided below the counterweight 3. Each weight guide device 9b is slidably engaged with the opposing weight guide rail 4b. Therefore, the counterweight 3 ascends and descends in the hoistway 100 along the pair of weight guide rails 4b while being guided by the pair of weight guide rails 4b.
　乗りかご１の下部には、非常時に、制動子によって、かご用ガイドレール４ａを挟持して、乗りかご１の昇降を停止させる非常止め装置２が配置されている。なお、本実施例１では、非常止め装置２は、乗りかご１の下部の左右に一台ずつ設けられる。非常止め装置２は、非常時に、乗りかご１上に設けられる電動駆動機構１０によって駆動され、制動状態となる。 At the bottom of the car 1, an emergency stop device 2 is arranged that stops the car 1 from going up and down by clamping the car guide rails 4a with brakes in an emergency. In addition, in the first embodiment, the safety devices 2 are provided one by one on the left and right sides of the lower part of the car 1 . In an emergency, the safety device 2 is driven by an electric drive mechanism 10 provided on the car 1 to enter a braking state.
　図２は、図１における電動駆動機構１０を含む乗りかご１まわりの詳細構成図である。 FIG. 2 is a detailed configuration diagram around the car 1 including the electric drive mechanism 10 in FIG.
　図２に示すように、乗りかご１上に設けられる電動駆動機構１０は、非常止め装置２を駆動する駆動機構（１２～２０）と、駆動機構（１２～２０）を作動させる電動作動器３０を備えている。 As shown in FIG. 2, the electric drive mechanism 10 provided on the car 1 includes drive mechanisms (12 to 20) that drive the safety device 2, and an electric actuator 30 that operates the drive mechanisms (12 to 20). It has
　駆動機構（１２～２０）は、乗りかご１上に設けられる支持部材、本実施例１では、クロスヘッド５０によって支持されている。クロスヘッド５０は、乗りかご１を支持するかご枠を構成する上枠であり、本実施例１では、一定の断面形状（Ｃ形、コ（日本語の片仮名）の字形など）を有する鋼材（溝形鋼）を複数本組み合わせて構成されている。なお、図２においては、縦枠および床枠などのかご枠構造部材は、図示を省略している。 The drive mechanisms (12-20) are supported by a support member provided on the car 1, which is the crosshead 50 in the first embodiment. The crosshead 50 is an upper frame that constitutes a car frame that supports the car 1. In the first embodiment, a steel material ( channel steel) are combined together. In FIG. 2, illustration of car frame structural members such as vertical frames and floor frames is omitted.
　電動作動器３０は、駆動機構（１２～２０）の下方に設けられる。本実施例１では、電動作動器３０は、クロスヘッド５０を構成する鋼材の平面部からなる基板部４０上に、載置されて固定されている。 The electric actuator 30 is provided below the drive mechanism (12-20). In the first embodiment, the electric actuator 30 is placed and fixed on a base plate portion 40 that is a plane portion of a steel material that constitutes the crosshead 50 .
　電動作動器３０は、本実施例１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。本実施例１では、電動作動器３０は、電磁石によって作動する操作レバー１１を備える。電動作動器３０は、速度検出装置（図示せず）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、乗りかご１に設けられる引上げロッド２１が引き上げられる。引上げロッド２１が引き上げられると、引上げロッド２１によって非常止め装置２の制動子（図示せず）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 30 is an electromagnetic operator in the first 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. In the first embodiment, the electric actuator 30 has an operating lever 11 that is operated by an electromagnet. The electric actuator 30 is activated when a speed detector (not shown) detects a predetermined overspeed condition of the car 1 . At this time, the drive mechanism (12-20) mechanically connected to the operating lever 11 pulls up the pull-up rod 21 provided on the car 1. As shown in FIG. When the lifting rod 21 is lifted, the brake shoe (not shown) of the safety device 2 is lifted by the lifting rod 21 . As a result, the safety device 2 is brought into a braking state.
　前述の速度検出装置（図示せず）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、速度検出装置により、乗りかご１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 aforementioned speed detection device (not shown) 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. To detect. Therefore, the speed detector can detect that the elevator car 1 has exceeded a predetermined overspeed.
　本実施例１では、速度検出装置（図示せず）は、画像センサを備え、画像センサによって取得されるかご用ガイドレール４ａ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かご用ガイドレール４ａ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 speed detection device (not shown) 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 car guide rail 4a acquired by the image sensor. To detect. For example, the position of the car 1 is detected by collating the image information of the surface condition of the car guide rail 4a measured in advance and stored in the storage device with the image information obtained by the image sensor.
　なお、速度検出装置としては、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。 A rotary encoder that is provided on the car and rotates as the car moves may be used as the speed detection device.
　前述のように、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が備える一対の制動子（図示せず）は、制動位置および非制動位置の間で可動であり、非常時には引上げロッド２１によって非制動位置から制動位置に移動される。制動位置において、一対の制動子（図示せず）は、かご用ガイドレール４ａ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、制動子とかご用ガイドレール４ａ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。 As described above, 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 is movable between a braking position and a non-braking position, and is moved from the non-braking position to the braking position by a lifting rod 21 in an emergency. At the braking position, a pair of brakes (not shown) sandwich the car guide rails 4a, and when the car 1 descends and rises relatively, there is a gap between the brakes and the car guide rails 4a. The acting frictional force produces the braking force. 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.
　電動駆動機構１０が備える駆動機構（１２～２０）および電動作動器３０の構成および動作、駆動機構（１２～２０）および電動作動器３０の動作音を低減する手段については後述する。 The configuration and operation of the drive mechanisms (12-20) and the electric actuator 30 included in the electric drive mechanism 10, and the means for reducing the operating noise of the drive mechanisms (12-20) and the electric actuator 30 will be described later.
　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、巻上機の電源およびこの巻上機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３０が電気的に駆動され、非常止め装置２を作動させて、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 double) is reached, power to the hoist and to the control device controlling this hoist is shut off. Further, 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 30 provided in the car 1 is electrically driven, causing an emergency. The stop device 2 is operated to bring the car 1 to an emergency stop.
　本実施例１において、ロープレスガバナシステムは、前述の速度検出装置（図示せず）と、速度検出装置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（図示せず）とから構成される。この安全制御装置は、速度検出装置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、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３０を作動するための指令信号を出力する。 In the first embodiment, the ropeless governor system includes the aforementioned speed detector (not shown) and a safety control device (not shown) that determines an overspeed condition of the car 1 based on the output signal of the speed detector. It consists of This safety control device measures the speed of the car 1 based on the output signal of the speed detection device, and when it determines that the measured speed has reached the first overspeed, it turns off the power source of the hoist and this drive device. It outputs a command signal for shutting off the power supply of the controlling 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 30 .
　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３０の操作レバー１１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 operating lever 11 of the electric actuator 30. As shown in FIG.
　以下、この駆動機構（１２～２０）の構成および動作について説明する。 The configuration and operation of this drive mechanism (12-20) will be described below.
　図２に示すように、電動作動器３０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、乗りかご１が有する構造部材であるクロスヘッド５０（かご枠の上枠）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。 As shown in FIG. 2, the operating lever 11 of the electric actuator 30 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 connects the operating lever 11 and the first operating piece 16 to the crosshead 50 (car The upper frame of the frame) is rotatably supported. One end (the left side in the figure) 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. .
　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（図中左側）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 . At the end of the second operating piece 18, which is the leg of the T-shape, opposite to the connecting portion between the connecting piece 17 and the second operating piece 18, the other of the pair of lifting rods 21 (left side in the figure) is attached. The ends are connected.
　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。 An end portion of the operating lever 11 and an end portion of the connecting piece 17 closer to the top of the car 1 than the second operating shaft 20 is respectively one end of the drive shaft 12 lying on the car 1. (left side in the drawing) and the other end (right side in the drawing).
　なお、電動作動器３０は、保護用のカバー部材によって覆われていてもよい。この場合、操作レバー１１は、カバー部材の開口部を通って、カバー部材の外部へ突出する。 The electric actuator 30 may be covered with a protective cover member. In this case, the operating lever 11 protrudes outside the cover member through the opening of the cover member.
　駆動軸１２は、クロスヘッド５０に固定される固定部１４を、移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１５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、移動可能に挿通される。なお、本実施例１では、駆動バネ１３として、コイル状の圧縮バネが適用される。 The drive shaft 12 movably penetrates the fixing portion 14 fixed to the crosshead 50 . Further, the drive shaft 12 passes through the pressing member 15 , and the pressing member 15 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 movably inserted through the drive spring 13 . In addition, in the first embodiment, a coiled compression spring is applied as the drive spring 13 .
　なお、本実施例１では、駆動バネ１３の一端は、固定部１４に固定される。したがって、駆動バネ１３の一端は、固定部１４を介して、クロスヘッド５０に固定される。また、駆動バネ１３の他端は、押圧部材１５に固定される。したがって、駆動バネ１３の他端は、押圧部材１５を介して、駆動軸１２に固定される。このように、駆動バネ１３の一端は固定端であり、駆動バネ１３の他端は、駆動軸１２の押圧部とともに動く自由端である。 Note that one end of the drive spring 13 is fixed to the fixing portion 14 in the first embodiment. Accordingly, one end of the drive spring 13 is fixed to the crosshead 50 via the fixing portion 14 . Also, the other end of the drive spring 13 is fixed to the pressing member 15 . Therefore, the other end of the drive spring 13 is fixed to the drive shaft 12 via the pressing member 15 . Thus, one end of the drive spring 13 is a fixed end and the other end of the drive spring 13 is a free end that moves together with the pressing portion of the drive shaft 12 .
　なお、クロスヘッド５０による部材の支持や、クロスヘッド５０における部材の固定は、クロスヘッド５０対して直接でもよいし、クロスヘッド５０に固定される支持部材を介してでもよい。 The support of the members by the crosshead 50 and the fixing of the members on the crosshead 50 may be performed directly on the crosshead 50 or via a support member fixed to the crosshead 50 .
　電動作動器３０が作動すると、すなわち本実施例１では電磁石（後述する図３中の「３５」）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 30 operates, that is, when the electromagnet (“35” in FIG. 3 to be described later) is deenergized in the first embodiment, the operating lever 11 moves against the biasing force of the drive spring 13. Since the electromagnetic force that restrains is lost, the driving shaft 12 is driven along the longitudinal direction by the biasing force of the driving spring 13 applied to the pressing member 15 . 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 pulled up, and the other lifting rod 21 connected to the second operating piece 18 of the second link member is pulled up. The rod 21 is driven up.
　上述のような、電動駆動機構１０の動作時には、駆動機構（１２～２０）および電動作動器３０に生じる機械的振動が、電動駆動機構１０の動作音として、エレベータ装置の構造部材や空気を介して、昇降路内外に伝搬する。この場合、電動駆動機構１０が設けられる乗りかご１内には、クロスヘッド５０を含むかご枠などの、かご構造部材や、かご室を構成する側板などを介して、動作音が伝搬する。このため、乗りかご１内に乗客がいる場合、乗客は、異常音を感じる。そこで、本実施例１においては、次に説明するように、電動駆動機構１０の支持部材であるクロスヘッド５０と乗りかご１との間に、駆動機構（１２～２０）および電動作動器３０に生じる機械的振動の伝搬を抑制する防振部が設けられる。 During the operation of the electric drive mechanism 10 as described above, mechanical vibrations generated in the drive mechanisms (12 to 20) and the electric actuator 30 are transmitted as operating sounds of the electric drive mechanism 10 through structural members of the elevator system and air. propagate inside and outside the hoistway. In this case, inside the car 1 in which the electric drive mechanism 10 is provided, the operation sound propagates through the car structural members such as the car frame including the crosshead 50 and the side plates constituting the car room. Therefore, when there is a passenger in the car 1, the passenger feels an abnormal sound. Therefore, in the first embodiment, as described below, the drive mechanisms (12 to 20) and the electric actuator 30 are installed between the crosshead 50, which is a support member of the electric drive mechanism 10, and the car 1. A vibration isolator is provided to suppress the propagation of mechanical vibrations that occur.
　図２に示すように、クロスヘッド５０の下部の平面部（基板部４０）と乗りかご１の天井板６０との間に、防振部として、防振ゴム６１が設けられる。防振ゴム６１は、クロスヘッド５０の長手方向の両端部の一方および他方の各下方に設けられる。なお、本実施例１では、クロスヘッド５０に乗りかご１の天井板６０を固定する吊りボルト６２もクロスヘッド５０の両端部に位置するが、防振ゴム６１は、吊りボルト６２よりも、クロスヘッド５０の長手方向の先端の近くに位置する。 As shown in FIG. 2, a vibration isolating rubber 61 is provided as a vibration isolating part between the lower planar part (substrate part 40) of the crosshead 50 and the ceiling plate 60 of the car 1. Anti-vibration rubbers 61 are provided below both ends of the crosshead 50 in the longitudinal direction. In the first embodiment, the hanging bolts 62 for fixing the ceiling plate 60 of the car 1 to the crosshead 50 are also positioned at both ends of the crosshead 50 , but the vibration-proof rubbers 61 are arranged in the cross direction rather than the hanging bolts 62 . Located near the longitudinal extremity of head 50 .
　防振ゴム６１は、その両端部から突出するネジ部と、このネジ部に螺合するナットとによって、クロスヘッド５０および天井板６０に、ネジの軸方向に弾性変形（伸縮）可能に固定される。すなわち、クロスヘッド５０と乗りかご１の天井板６０とが、弾性体である防振ゴムを介して、接続される。なお、防振ゴム６１のネジ部は、防振ゴム６１を貫通する棒状ネジでもよいし、ネジ付き防振ゴムが備える両端ネジでもよい。 The anti-vibration rubber 61 is fixed to the crosshead 50 and the ceiling plate 60 by means of threaded portions protruding from both ends thereof and nuts screwed onto the threaded portions so as to be elastically deformable (expandable) in the axial direction of the screws. be. That is, the crosshead 50 and the ceiling plate 60 of the car 1 are connected via the vibration isolating rubber, which is an elastic body. The threaded portion of the vibration isolator 61 may be a rod-shaped screw penetrating the vibration isolator 61, or may be a screw on both ends of a threaded vibration isolator.
　なお、吊りボルト６２は、クロスヘッド５０側に位置する頭部側はクロスヘッド５０に固定されず、摺動可能状態にある。したがって、吊りボルト６２が防振ゴム６１の弾性変形を妨げることが防止される。 It should be noted that the hanging bolt 62 is not fixed to the crosshead 50 on the head side located on the crosshead 50 side and is in a slidable state. Therefore, it is possible to prevent the suspension bolt 62 from interfering with the elastic deformation of the anti-vibration rubber 61 .
　このように、電動駆動機構１０を構成する駆動機構（１２～２０）および電動作動器３０と、乗りかご１の天井板６０との間に弾性体である防振ゴム６１が設けられていることにより、電動駆動機構１０に生じる機械的振動は、防振ゴム６１によって減衰され、乗りかご１への伝搬が抑制される。これにより、電動駆動機構１０から乗りかご１の内外へ伝わる電動駆動機構１０の動作音が抑制される。 Thus, the vibration isolator 61, which is an elastic body, is provided between the drive mechanism (12 to 20) and the electric actuator 30 that constitute the electric drive mechanism 10 and the ceiling plate 60 of the car 1. Accordingly, the mechanical vibration generated in the electric drive mechanism 10 is attenuated by the anti-vibration rubber 61, and its propagation to the car 1 is suppressed. As a result, the operation noise of the electric drive mechanism 10 that is transmitted from the electric drive mechanism 10 to the inside and outside of the car 1 is suppressed.
　図３は、本実施例１における電動作動器３０の機構部を示し、図２の設置状態における正面図である。なお、図３において、非常止め装置は非制動状態であり、電動作動器３０は待機状態にある。すなわち、エレベータ装置は、通常の運転状態である。 FIG. 3 shows the mechanical portion of the electric actuator 30 in the first embodiment, and is a front view in the installation state of FIG. In FIG. 3, the safety device is in a non-braking state, and the electric actuator 30 is in a standby state. That is, the elevator installation is in normal operating condition.
　図３に示すように、待機状態においては、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に対向して、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。これにより、駆動バネ１３（図２）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。したがって、電動作動器３０は、駆動バネ１３の付勢力に抗して、駆動機構の動きを拘束している。 As shown in FIG. 3, in the standby state, the movable member 34 connected to the operating lever 11 causes the electromagnet 35, whose magnetic pole surface faces the movable member 34 and is excited by the coil to be energized, to generate an electromagnetic force. is adsorbed by As a result, the movement of the operating lever 11 is restrained against the biasing force of the drive spring 13 (FIG. 2). Therefore, the electric actuator 30 restrains the movement of the drive mechanism against the biasing force of the drive spring 13 .
　操作レバー１１は、可動部材３４に回動可能に設けられる接続部材である接続ブラケット３８を介して、可動部材３４に接続される。操作レバー１１の一端は接続ブラケット３８に固定される。 The operation lever 11 is connected to the movable member 34 via a connection bracket 38 which is a connection member rotatably provided on the movable member 34 . One end of the operating lever 11 is fixed to the connection bracket 38 .
　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.
　図３中における他の機構部（３６，３７，３９－４２，４９，５５）については、後述する。 Other mechanism units (36, 37, 39-42, 49, 55) in FIG. 3 will be described later.
　図４は、本実施例１における電動作動器３０の機構部を示し、図１の設置状態における正面図である。なお、図４において、非常止め装置は制動状態であり、電動作動器３０は作動状態にある。すなわち、エレベータ装置は、非常止め装置により停止された状態である。 FIG. 4 shows the mechanical portion of the electric actuator 30 in the first embodiment, and is a front view in the installation state of FIG. In FIG. 4, the safety device is in the braking state, and the electric actuator 30 is in the operating state. That is, the elevator system is in a state of being stopped by the safety device.
　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、駆動軸１２の押圧部材１５（図２）が受ける、固定部１４（図２）から押圧部材１５へ向かう方向の、駆動バネ１３（図２）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 constraint of the operating lever 11 due to the movable member 34 being attracted to the electromagnet 35, so that the pressing member 15 (FIG. 2) of the drive shaft 12 receives from the fixed portion 14 (FIG. 2) to the pressing member 15. The drive shaft 12 is driven by the biasing force of the drive spring 13 (FIG. 2) in the facing direction.
　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（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 (operating lever 11 and first operating piece) connected to the drive shaft 12 rotates 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、前述の図３に示す可動部材３４の位置から本図４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 of the movable member 34 shown in FIG. to the position of the movable member 34 shown in FIG.
　電動作動器３０を図３に示したような待機状態に復帰させるためには、次に述べるように、図３で説明を省略した機構部（３６，３７，３９－４２，４９，５５）によって、可動部材３４を移動位置（図４）から待機時の位置（図３）に戻す。 In order to return the electric actuator 30 to the standby state shown in FIG. , the movable member 34 is returned from the movement position (FIG. 4) to the standby position (FIG. 3).
　図４に示すように、電動作動器３０は、可動部材３４を駆動するために基板部４０の平面部上に位置する送りねじ３６を有する。送りねじは、基板部４０の平面上に固定される第１の送りねじ支持部材４１および第２の送りねじ支持部材４２によって回転可能に支持される。電磁石３５は、送りナット３９を備える支持板４９に固定されている。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。なお、モータ３７は、モータ固定ブラケット５５によって基板部４０の平面上に固定的に支持される。 As shown in FIG. 4 , the electric actuator 30 has a feed screw 36 located on the flat surface of the base plate 40 to drive the movable member 34 . The feed screw is rotatably supported by a first feed screw support member 41 and a second feed screw support member 42 fixed on the plane of the base plate portion 40 . Electromagnet 35 is fixed to support plate 49 with lead nut 39 . A feed nut 39 is screwed onto the feed screw 36 . Feed screw 36 is rotated by motor 37 . The motor 37 is fixedly supported on the plane of the substrate portion 40 by a motor fixing bracket 55 .
　電動作動器３０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３６を回転させる。回転する送りねじ３６と電磁石３５が備える送りナット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４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。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。 To return the electric actuator 30 to the standby state, first, while exciting the electromagnet 35 , the motor 37 is driven to rotate the feed screw 36 . 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 . As a result, the electromagnet 35 approaches the moving position of the movable member 34 shown in FIG. 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.
　なお、電磁石３５は、可動部材３４に当接した後に励磁されてもよい。 It should be noted that the electromagnet 35 may be excited after coming into contact with the movable member 34 .
　非常止め装置の電動駆動機構１０（図２）は、上述のように、電磁石が消磁されて駆動機構（１２～２０）が動作するとき、および送りねじ３６を回転させて電動作動器３０を待機状態に復帰させるときに、動作音を発生する。このような動作音が、本実施例１では、防振部である防振ゴム６１（図２）により吸収される。このため、電動駆動機構１０から乗りかご１内外に伝わる動作音が抑制される。 As described above, the electric drive mechanism 10 (FIG. 2) of the safety device operates when the electromagnet is demagnetized and the drive mechanism (12-20) operates, and when the feed screw 36 is rotated to wait for the electric actuator 30. When returning to the state, an operation sound is generated. In the first embodiment, such operating noise is absorbed by the vibration isolator 61 (FIG. 2), which is a vibration isolator. Therefore, the operation noise transmitted from the electric drive mechanism 10 to the inside and outside of the car 1 is suppressed.
　なお、停電時においても、電動作動器３０の電磁石３５は消磁するため、非常止め装置２の駆動機構（１２～２０）が動作する。したがって、停電時においても、電動駆動機構１０は動作音を発生する。また、停電時における最寄り階運転や、復電時における自動復旧において、安全制御装置からの指令によって、電動作動器３０は通常状態に復帰する。このとき、電動作動器３０が動作音を発生する。したがって、本実施例１によれば、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、電動駆動機構１０の動作音を抑制できる。 It should be noted that the drive mechanism (12 to 20) of the safety device 2 operates even during a power failure because the electromagnet 35 of the electric actuator 30 is demagnetized. Therefore, the electric drive mechanism 10 generates operating noise even during a power failure. In addition, the electric actuator 30 is returned to the normal state by a command from the safety control device in the operation of the nearest floor at the time of power failure or automatic restoration at the time of power restoration. At this time, the electric actuator 30 generates an operating sound. Therefore, according to the first embodiment, the operation noise of the electric drive mechanism 10 can be suppressed not only when the overspeed state of the car is detected, but also when power failure occurs.
　上述のように、本実施例１によれば、非常止め装置２を駆動する電動駆動機構と乗りかご１との間に、防振部として、弾性体である防振ゴム６１が設けられることにより、電動駆動機構１０の動作音を抑制できる。 As described above, according to the first embodiment, the rubber vibration isolator 61, which is an elastic body, is provided as a vibration isolator between the electric drive mechanism that drives the safety device 2 and the car 1. , the operating noise of the electric drive mechanism 10 can be suppressed.
　なお、防振ゴム６１に代えて、他の弾性体、例えば、バネ（皿バネ、板バネ、コイル状バネなど）や弾性樹脂など、を適用してもよい。 It should be noted that instead of the rubber vibration isolator 61, other elastic bodies such as springs (disc springs, leaf springs, coil springs, etc.) or elastic resin may be applied.
　図５は、本発明の実施例２であるエレベータ装置における乗りかご１まわりの詳細構成図である。なお、全体構成および電動作動器３０の構成は、実施例１（図１、図３－４）と同様である。 FIG. 5 is a detailed configuration diagram around one car in an elevator system that is Embodiment 2 of the present invention. The overall configuration and the configuration of the electric actuator 30 are the same as those of the first embodiment (FIGS. 1 and 3-4).
　以下、実施例１（図２）と異なる点について説明する。 The points that differ from the first embodiment (Fig. 2) will be described below.
　図５に示すように、本実施例２においては、クロスヘッド５０が複数の支持ブラケット７２を介して乗りかご１上に固定される。各支持ブラケット７２は、電動作動器３０が設けられる、クロスヘッド５０の平面部からなる基板部４０と、乗りかご１の天井板６０とに、ボルト締結によって固定される。 As shown in FIG. 5 , in the second embodiment, the crosshead 50 is fixed on the car 1 via a plurality of support brackets 72 . Each support bracket 72 is fixed by bolting to the base plate portion 40 consisting of the flat portion of the crosshead 50 on which the electric actuator 30 is provided and the ceiling plate 60 of the car 1 .
　支持ブラケット７２を挟んで対向する基板部４０と天井板６０との間の空間には、防振部として、吸音材７１が充填される。吸音材７１としては、多孔質材が好ましく、例えば、発泡樹脂（発泡ウレタン、発泡ゴムなど）、スポンジ、グラスウール、ロックウールなどが適用される。 The space between the substrate portion 40 and the ceiling plate 60 facing each other with the support bracket 72 interposed therebetween is filled with a sound absorbing material 71 as a vibration isolating portion. As the sound absorbing material 71, a porous material is preferable, and for example, foamed resin (urethane foam, foamed rubber, etc.), sponge, glass wool, rock wool, etc. are applied.
　このように、電動駆動機構１０を構成する駆動機構（１２～２０）および電動作動器３０と、乗りかご１の天井板６０との間に吸音材７１が設けられていることにより、電動駆動機構１０が発生する動作音は、吸音材７１によって吸収され、乗りかご１への伝搬が抑制される。これにより、電動駆動機構１０から乗りかご１の内外へ伝わる電動駆動機構１０の動作音が抑制される。 In this way, the sound absorbing material 71 is provided between the drive mechanisms (12 to 20) and the electric actuator 30 that constitute the electric drive mechanism 10 and the ceiling plate 60 of the car 1, so that the electric drive mechanism The operating sound generated by 10 is absorbed by the sound absorbing material 71 and is suppressed from propagating to the car 1 . As a result, the operation noise of the electric drive mechanism 10 that is transmitted from the electric drive mechanism 10 to the inside and outside of the car 1 is suppressed.
　上述のように、本実施例１によれば、非常止め装置２を駆動する電動駆動機構１０と乗りかご１との間に、防振部として、吸音材７１が設けられることにより、電動駆動機構１０の動作音を抑制できる。 As described above, according to the first embodiment, the sound absorbing material 71 is provided as a vibration isolator between the electric drive mechanism 10 that drives the safety device 2 and the car 1, so that the electric drive mechanism 10 operating sounds can be suppressed.
　なお、本発明は前述した実施例１～２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１～２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、各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 first and second embodiments described above, and includes various modifications. For example, the first and second embodiments described above have been described in detail in order to explain the present invention in an easy-to-understand manner, and are not necessarily limited to those having all the configurations described. Moreover, it is possible to add, delete, or replace a part of the configuration of each embodiment with another configuration.
　例えば、非常止め装置の駆動機構（１２～２０）および電動作動器３０は、乗りかご１の上方部のほか、下方部や側方部に設けられてもよい。この場合、駆動機構および電動作動器は、適宜、かご構造部材に設けられる。なお、上記実施例では、駆動機構（１２～２０）および電動作動器３０は、クロスヘッド５０の高さ方向の上端部よりも低い領域内に設置されている。これにより、オーバーヘッド寸法を増大することなく、駆動機構（１２～２０）および電動作動器３０を乗りかご１上に設けることができる。 For example, the drive mechanism (12 to 20) of the safety device and the electric actuator 30 may be provided in the upper part of the car 1, as well as in the lower part or the side part. In this case, the drive mechanism and the electric actuator are suitably provided on the car structural member. In the above embodiment, the drive mechanisms (12-20) and the electric actuator 30 are installed in a region lower than the upper end of the crosshead 50 in the height direction. This allows the drive mechanism (12-20) and the electric actuator 30 to be provided on the car 1 without increasing the overhead dimensions.
　また、エレベータ装置は、いわゆる機械室レスエレベータでもよい。 Also, the elevator device may be a so-called machine room-less elevator.
　なお、上述した防音手段は、上述の実施例に限らず、駆動機構が非常止め装置に接続される駆動軸を備え、駆動軸がバネによって付勢され、かつ電動作動器が、待機状態において、バネの付勢力に抗して駆動機構を拘束し、非常止め装置を動作させるとき、駆動機構の拘束を解くような電動駆動機構を備えるエレベータ装置に適用できる。 Note that the above-described soundproofing means is not limited to the above-described embodiment, and the drive mechanism includes a drive shaft connected to the safety device, the drive shaft is biased by a spring, and the electric actuator is in a standby state. The present invention can be applied to an elevator apparatus equipped with an electric drive mechanism that restrains the drive mechanism against the urging force of the spring and releases the restraint of the drive mechanism when operating the safety device.
　このようなエレベータ装置においては、電動作動器が、駆動機構に接続される操作レバーと、操作レバーに接続される可動部材と、可動部材に対向する電磁石と、を備え、待機状態においては、可動部材が電磁石に吸着されることによって、操作レバーの動きが拘束され、非常止め装置を動作させるとき、電磁石が消磁されることが好ましい。 In such an elevator apparatus, the electric actuator includes an operation lever connected to the drive mechanism, a movable member connected to the operation lever, and an electromagnet facing the movable member. It is preferable that the member is attracted to the electromagnet so that the movement of the operating lever is restrained and the electromagnet is demagnetized when operating the safety device.
　さらに、電動作動器は、電磁石を移動する移動機構部を備え、非常止め装置の動作後に、移動機構部によって電磁石を移動して、可動部材を電磁石に吸着し、移動機構部によって電磁石を移動して、電磁石に吸着された可動部材を待機状態の位置に移動してもよい。 Further, the electric actuator includes a movement mechanism that moves the electromagnet, and after the safety device operates, the movement mechanism moves the electromagnet to attract the movable member to the electromagnet, and the movement mechanism moves the electromagnet. to move the movable member attracted to the electromagnet to the position of the standby state.
