In the figure, a pair of car guide rails 2 are installed in a hoistway 1. The car 3 is guided up and down the hoistway 1 by the car guide rails 2. At the upper end of the hoistway 1, a hoist (not shown) for raising and lowering the car 3 and the counterweight (not shown) is arranged. The main rope 4 is wound around the drive sheave of the hoisting machine. The car 3 and the counterweight are suspended in the hoistway 1 by the main rope 4. On the car 3, a pair of safety devices 5, which are braking means, are mounted so as to face each car guide rail 2. Each safety device 5 is arranged at the lower part of the car 3. The car 3 is braked by the operation of each safety device 5.
また、 昇降路 1の上端部には、 かご 3の昇降速度を検出するかご速度検出手段 である調速機 6が配置されている。 調速機 6は、 調速機本体 7と、 調速機本体 7 に対して回転可能な調速機シープ 8とを有している。 昇降路 1の下端部には、 回 転可能な張り車 9が配置されている。 調速機シーブ 8と張り車 9との間には、 か ご 3に連結されたガバナロープ 1 0が卷き掛けられている。 ガバナロープ 1 0の かご 3との連結部は、 かご 3とともに上下方向へ往復動される。 これにより、 調 速機シーブ 8及ぴ張り車 9は、 かご 3の昇降速度に対応した速度で回転される。 調速機 6は、 かご 3の昇降速度が予め設定された第 1過速度となったときに巻 上機のブレーキ装置を作動させるようになつている。 また、 調速機 6には、 かご 3の降下速度が第 1過速度よりも高速の第 2過速度 (設定過速度) となったとき に非常止め装置 5へ作動信号を出力する出力部であるスィッチ部 1. 1が設けられ ている。 スィッチ部 1 1は、 回転する調速機シープ 8の遠心力に応じて変位され る過速レバーによって機械的に開閉される接点部 1 6を有している。 接点部 1 6 は、 停電時にも給電可能な無停電電源装置であるパッテリ 1 2、 及びエレベータ の運転を制御する制御盤 1 3に、 それぞれ電源ケーブル 1 4及び接続ケーブル 1 5によって電気的に接続されている。 At the upper end of the hoistway 1, a speed governor 6 serving as a car speed detecting means for detecting the hoisting speed of the car 3 is arranged. The governor 6 has a governor body 7 and a governor sheep 8 rotatable with respect to the governor body 7. At the lower end of the hoistway 1, a rotatable pulley 9 is arranged. A governor rope 10 connected to the car 3 is wound between the governor sheave 8 and the tensioner 9. Governor rope 10 The connection part with the car 3 is reciprocated with the car 3 in the vertical direction. As a result, the governor sheave 8 and the stretcher 9 are rotated at a speed corresponding to the elevator speed of the car 3. The governor 6 operates the brake device of the hoist when the elevator speed of the car 3 reaches a preset first overspeed. Also, the governor 6 has an output unit that outputs an operation signal to the safety gear 5 when the descending speed of the car 3 becomes a second overspeed (set overspeed) higher than the first overspeed. There is a switch 1.1. The switch part 11 has a contact part 16 that is mechanically opened and closed by an overspeed lever that is displaced according to the centrifugal force of the rotating governor sheep 8. The contact section 16 is electrically connected to the battery 12 as an uninterruptible power supply that can supply power even during a power failure, and to the control panel 13 that controls the operation of the elevator via a power cable 14 and a connection cable 15, respectively. Have been.
かご 3 ·と制御盤 1 3との間には、 制御ケ一ブル (移動ケーブル) が接続されて いる。 制御ケーブルには、 複数の電力線や信号線と共に、 制御盤 1 3と各非常止 め装置 5との間に電気的に接続された非常止め用配線 1 7が含まれている。 バッ テリ 1 2からの電力は、 接点部 1 6の閉極により、 電源ケーブル 1 4、 スィッチ 部 1 1、 接続ケーブル 1 5、 制御盤 1 3内の電力供給回路及び非常止め用配線 1 7を通じて各非常止め装置 5へ供給される。 なお、 伝送手段は、 接続ケーブル 1 5、 制御盤 1 3内の電力供給回路及び非常止め用配線 1 7を有している。  A control cable (moving cable) is connected between the car 3 and the control panel 13. The control cable includes an emergency stop wiring 17 electrically connected between the control panel 13 and each emergency stop device 5 together with a plurality of power lines and signal lines. The power from the battery 12 is passed through the power cable 14, the switch 11, the connection cable 15, the power supply circuit in the control panel 13, and the emergency stop wiring 17 by closing the contacts 16.

図 2は図 1の非常止め装置 5を示す正面図であり、 図 3は図 2の作動時の非常 止め装置 5を示す正面図である。 図において、 かご 3の下部には、 支持部材 1 8 が固定されている。 非常止め装置 5は、 支持部材 1 8に支持されている。 また、 各非常止め装置 5は、 かごガイドレール 2に対して接離可能な一対の制動部材で ある楔 1 9と、 楔 1 9に連結され、 かご 3に対して楔 1 9を変位させる一対のァ クチユエータ部 2 0と、 支持部材 1 8に固定され、 ァクチユエータ部 2 0により 変位される楔 1 9をかごガイドレール 2に接する方向へ案内する一対の案内部 2 1とを有している。 一対の楔 1 9、 一対のァクチユエータ部 2 0及ぴ一対の案内 部 2 1は、 それぞれかごガイドレール 2の両側に対称に配置されている。  FIG. 2 is a front view showing the emergency stop device 5 of FIG. 1, and FIG. 3 is a front view showing the emergency stop device 5 at the time of operation of FIG. In the figure, a support member 18 is fixed to the lower part of the car 3. The emergency stop device 5 is supported by a support member 18. Further, each safety device 5 has a pair of braking members wedges 19 which can be brought into contact with and separated from the car guide rail 2, and a pair of wedges 19 connected to the wedges 19 to displace the wedges 19 with respect to the car 3. And a pair of guide portions 21 fixed to the support member 18 and guiding the wedge 19 displaced by the actuator portion 20 in a direction in contact with the car guide rail 2. . The pair of wedges 19, the pair of actuator sections 20 and the pair of guide sections 21 are respectively symmetrically arranged on both sides of the car guide rail 2.
案内部 2 1は、 かごガイドレール 2との間隔が上方で小さくなるようにかごガ ィドレール 2に対して傾斜された傾斜面 2 2を有している。 楔 1 9は、 傾斜面 2 2に沿って変位される。 ァクチユエータ部 2 0は、 楔 1 9を上方の案内部 2 1側 へ付勢する付勢部であるばね 2 3と、 通電による電磁力によりばね 2 3の付勢に 逆らって案内部 2 1から離れるように楔 1 9を下方へ変位させる電磁マグネット 2 4とを有している。 The guide portion 21 has an inclined surface 22 that is inclined with respect to the car guide rail 2 so that the distance from the car guide rail 2 decreases upward. Wedge 1 9 is slope 2 Displaced along 2 The actuator section 20 is provided with a spring 23, which is an urging section for urging the wedge 19 to the upper guide section 21 side, and a guide section 21 against the urging of the spring 23 by an electromagnetic force generated by energization. And an electromagnetic magnet 24 for displacing the wedge 19 downward so as to separate.
ばね 2 3は、 支持部材 1 8と楔 1 9との間に接続されている。 電磁マグネット 2 4は、 支持部材 1 8に固定されている。 非常止め用配線 1 7は、 .電磁マグネッ ト 2 4に接続されている。 楔 1 9には、 電磁マグネット 2 4に対向する永久磁石 2 5が固定されている。 電磁マグネット 2 4への通電は、 接点部 1 6 (図 1参 照) の閉極によりバッテリ 1 2 (図 1参照) 力 らなされる。 接点部 1 6 (図 1参 照) の開極により電磁マグネット 2 4への通電が遮断されることによって、 非常 止め装置 5は作動される。 即ち、 一対の楔 1 9は、 ばね 2 3の弾性復元力によつ てかご 3 ·に対して上方へ変位され、 かごガイドレール 2に押し付けられる。  The spring 23 is connected between the support member 18 and the wedge 19. The electromagnetic magnet 24 is fixed to the support member 18. The emergency stop wiring 17 is connected to the electromagnetic magnet 24. A permanent magnet 25 facing the electromagnetic magnet 24 is fixed to the wedge 19. Electromagnet 24 is energized by battery 12 (see Fig. 1) by closing contact point 16 (see Fig. 1). The emergency stop device 5 is actuated by shutting off the power to the electromagnetic magnet 24 by opening the contact portion 16 (see Fig. 1). That is, the pair of wedges 19 is displaced upward with respect to the car 3 · by the elastic restoring force of the spring 23 and pressed against the car guide rail 2.
次に、 動作について説明する。 通常運転時には、 接点部 1 6は閉極されている。 これにより、 電磁マグネット 2 4にはバッテリ 1 2から電力が供給されている。 楔 1 9は、 通電による電磁力により電磁マグネット 2 4に吸引保持され、 かごガ イドレール 2から開離されている (図 2 ) 。  Next, the operation will be described. During normal operation, the contact 16 is closed. As a result, power is supplied to the electromagnetic magnet 24 from the battery 12. The wedge 19 is attracted to and held by the electromagnetic magnet 24 by the electromagnetic force generated by energization, and is separated from the car guide rail 2 (FIG. 2).
例えば主ロープ 4の切断等によりかご 3の速度が上昇し第 1過速度になると、 卷上機のブレーキ装置が作動する。 卷上機のブレーキ装置の作動後においてもか ご 3の速度がさらに上昇し第 2過速度になると、 接点部 1 6が開極される。 これ により、 各非常止め装置 5の電磁マグネット 2 4への通電は遮断され、 楔 1 9は ばね 2 3の付勢によりかご 3に対して上方へ変位される。 このとき、 楔 1 9は案 内部 2 1の傾斜面 2 2に接触しながら傾斜面 2 2に沿って変位される。 この変位 により、 楔 1 .9はかごガイドレール 2に接触して押し付けられる。 楔 1 9は、 力 ごガイドレール 2への接触により、 さらに上方へ変位されてかごガイドレーノレ 2 と案内部 2 1との間に嚙み込む。 これにより、 かごガイドレール 2と楔 1 9との 間に大きな摩擦力が発生し、 かご 3が制動される (図 3 ) 。  For example, when the speed of the car 3 is increased to the first overspeed due to the cutting of the main rope 4 or the like, the brake device of the hoist operates. When the speed of the car 3 further increases and reaches the second overspeed even after the operation of the brake device of the hoisting machine, the contact portion 16 is opened. As a result, the power supply to the electromagnetic magnet 24 of each safety device 5 is cut off, and the wedge 19 is displaced upward with respect to the car 3 by the bias of the spring 23. At this time, the wedge 19 is displaced along the inclined surface 22 while contacting the inclined surface 22 of the plan interior 21. Due to this displacement, the wedge 1.9 comes into contact with the car guide rail 2 and is pressed. The wedge 19 is further displaced upward by the contact with the power guide rail 2 and is inserted between the car guide rail 2 and the guide portion 21. As a result, a large frictional force is generated between the car guide rail 2 and the wedge 19, and the car 3 is braked (FIG. 3).
かご 3の制動を解除するときには、 接点部 1 6の閉極により電磁マグネット 2 When releasing the braking of car 3, the electromagnetic magnet 2
4に通電した状態で、 かご 3を上昇させる。 これにより、 楔 1 9は下方へ変位さ れ、 かごガイ ドレール 2から開離される。 このようなエレベータ装置では、 バッテリ 1 2に接続されたスィッチ部 1 1と 各非常止め装置 5とが電気的に接続されているので、 調速機 6で検出されたかご 3の速度の異常を電気的な作動信号としてスィツチ部 1 1から各非常止め装置 5 へ伝送することができ、 かご 3の速度の異常が検出されてから短時間でかご 3を 制動させることができる。 これにより、 かご 3の制動距離を小さくすることがで きる。 しかも、 各非常止め装置 5を容易に同期作動させることができ、 かご 3を 安定して停止させることができる。 また、 非常止め装置 5は電気的な作動信号に より作動されるので、 かご 3の揺れ等による誤作動も防止することができる。 また、 非常止め装置 5は、 楔 1 9·を上方の案内部 2 1側へ変位させるァクチュ エータ部 2 0と、 上方へ変位される楔 1 9をかごガイドレール 2に接する方向へ 案内する傾斜面 2 2を含む案内部 2 1とを有しているので、 かご 3が下降してい るときに、 楔 1 9のかごガイドレール 2に対する押し付け力を確実に増大させる ことができる。 Raise car 3 while power is applied to 4. As a result, the wedge 19 is displaced downward and is separated from the car guide rail 2. In such an elevator system, since the switch section 11 connected to the battery 12 and each safety device 5 are electrically connected, the speed abnormality of the car 3 detected by the governor 6 is checked. An electric operation signal can be transmitted from the switch section 11 to each safety device 5, and the car 3 can be braked in a short time after the abnormal speed of the car 3 is detected. As a result, the braking distance of the car 3 can be reduced. In addition, the safety devices 5 can be easily operated synchronously, and the car 3 can be stopped stably. Further, since the emergency stop device 5 is operated by an electric operation signal, it is possible to prevent a malfunction due to a swing of the car 3 or the like. In addition, the safety device 5 includes an actuator portion 20 for displacing the wedges 19 to the upper guide portion 21 side and an inclination for guiding the wedges 19 to be displaced upward in a direction in contact with the car guide rail 2. Since the guide portion 21 including the surface 22 is provided, the pressing force of the wedge 19 against the car guide rail 2 can be reliably increased when the car 3 is descending.
また、 ァクチユエータ部 2 0は、 楔 1 9を上方へ付勢するばね 2 3と、 ばね 2 3の付勢に逆らって楔 1 9を下方へ変位させる電磁マグネット 2 4とを有してい るので、 簡単な構成で楔 1 9を変位させることができる。 実施の形態 2 .  Also, the actuator section 20 has a spring 23 for urging the wedge 19 upward and an electromagnetic magnet 24 for displacing the wedge 19 downward against the urging of the spring 23. However, the wedge 19 can be displaced with a simple configuration. Embodiment 2

The disc spring 46 is deformed by the reciprocating displacement of the movable part 40. The biasing direction of the disc spring 46 is reversed between the contact position (solid line) and the separation position (two-dot broken line) of the movable part 40 due to the deformation caused by the displacement of the movable part 40. ing. The movable portion 40 is held at the contact position and the separation position by the bias of the disc spring 46. That is, the contact state and the separated state of the contact portion 37 with the car guide rail 2 are held by the urging of the disc spring 46. The electromagnetic magnet 48 has a first electromagnetic unit 49 fixed to the movable unit 40, and a second electromagnetic unit 50 arranged to face the first electromagnetic unit 49. The movable section 40 is displaceable with respect to the second electromagnetic section 50. The emergency stop wiring 17 is connected to the electromagnetic magnet 48. The first electromagnetic unit 49 and the second electromagnetic unit 50 generate an electromagnetic force by the input of the operation signal to the electromagnetic magnet 48, and are repelled by each other. The first electromagnetic unit 49 is moved by the input of an operation signal to the electromagnetic magnet 48.
4 0とともに第 2電磁部 5 0から離れる向きへ変位される。 With 40, it is displaced away from the second electromagnetic unit 50.
なお、 出力部 3 2は、 非常止め機構 5の作動後の復帰のための復帰信号を復帰 時に出力するようになっている。 第 1電磁部 4 9及び第 2電磁部 5 0は、 電磁マ グネット 4 8への復帰信号の入力により互いに吸引される。 他の構成は実施の形 態 1と同様である。  The output unit 32 outputs a return signal for return after the operation of the emergency stop mechanism 5 at the time of return. The first electromagnetic unit 49 and the second electromagnetic unit 50 are attracted to each other by the input of the return signal to the electromagnetic magnet 48. Other configurations are the same as in Embodiment 1.
次に、 動作について説明する。 通常運転時には、 可動部 4 0は開離位置に位置 しており、 接触部 3 7は皿ばね 4 6の付勢によりかごガイドレール 2から開離さ れている。 接触部 3 7がかごガイドレール 2から開離された状態では、 楔 3 4は、 案内部 3 6との間隔が保たれており、 かごガイドレール 2から開離されている。 かご速度センサ 3 1で検出された速度が第 1過速度になると、 卷上機のブレー キ装置が作動する。 この後もかご 3の速度が上昇し、 かご速度センサ 3 1で検出 された速度が第 2過速度になると、 作動信号が出力部 3 2から各非常止め装置 3 3へ出力される。 作動信号の電磁マグネット 4 8への入力により、 第 1電磁部 4 9及び第 2電磁部 5 0は互いに反発される。 この電磁反発力により、 可動部 4 0 は接触位置へ変位される。 これに伴って、 接触部 3 7はかごガイドレール 2に対 して接触する方向へ変位される。 可動部 4 0が接触位置に達するまでに、 皿ばね 4 6の付勢の向きは接触位置で可動部 4 0を保持する向きに反転する。 これによ り、 接触部 3 7はかごガイドレール 2に接触して押し付けられ、 楔 3 4及ぴァク チユエータ部 3 5は制動される。 Next, the operation will be described. During normal operation, the movable part 40 is in the open position The contact portion 37 is separated from the car guide rail 2 by the urging of the disc spring 46. In a state in which the contact portion 37 is separated from the car guide rail 2, the wedge 34 is separated from the car guide rail 2 by keeping a distance from the guide portion 36. When the speed detected by the car speed sensor 31 becomes the first overspeed, the brake device of the hoist operates. Thereafter, when the speed of the car 3 increases and the speed detected by the car speed sensor 31 becomes the second overspeed, an operation signal is output from the output section 32 to each of the emergency stop devices 33. Due to the input of the operation signal to the electromagnetic magnet 48, the first electromagnetic unit 49 and the second electromagnetic unit 50 repel each other. The movable portion 40 is displaced to the contact position by the electromagnetic repulsion. Along with this, the contact portion 37 is displaced in a direction in which it comes into contact with the car guide rail 2. By the time the movable portion 40 reaches the contact position, the biasing direction of the disc spring 46 reverses to the direction in which the movable portion 40 is held at the contact position. As a result, the contact portion 37 comes into contact with and is pressed against the car guide rail 2, and the wedge 34 and the actuator portion 35 are braked.
かご 3及ぴ案内部 3 6は制動されずに下降することから、 案内部 3 6は下方の 楔 3 4及びァクチユエータ部 3 5側へ変位される。 この変位により、 楔 3 4は傾 斜面 4 4に沿って案内され、 かごガイドレール 2は楔 3 4及び接触面 4 5によつ て挟み付けられる。 楔 3 4は、 かごガイドレール 2への接触により、 さらに上方 へ変位されてかごガイドレール 2と傾斜面 4 4との間に嚙み込む。 これにより、 かごガイ ドレーノレ 2と楔 3 4との間、 及びかごガイドレール 2と接触面 4 5との 間に大きな摩擦力が発生し、 かご 3が制動される。  Since the car 3 and the guide portion 36 descend without being braked, the guide portion 36 is displaced to the lower side of the wedge 34 and the actuator portion 35. Due to this displacement, the wedge 34 is guided along the inclined surface 44, and the car guide rail 2 is sandwiched between the wedge 34 and the contact surface 45. The wedges 34 are displaced further upward by the contact with the car guide rails 2 and are inserted between the car guide rails 2 and the inclined surfaces 44. As a result, a large frictional force is generated between the car guide drain 2 and the wedge 34 and between the car guide rail 2 and the contact surface 45, and the car 3 is braked.
復帰時には、 出力部 3 2から復帰信号が電磁マグネット 4 8へ伝送される。 こ れにより、 第 1電磁部 4 9及ぴ第 2電磁部 5 0は互いに吸引され、 可動部 4 0は 開離位置へ変位される。 これに伴って、 接触部 3 7はかごガイドレール 2に対し て開離する方向へ変位される。 可動部 4 0が開離位置に達するまでに、 皿ばね 4 6の付勢の向きは反転し、 可動部 4 0は開離位置で保持される。 この状態で、 か ご 3が上昇され、 楔 3 4及び接触面 4 5のかごガイドレール 2に対する押し付け は解除される。  Upon return, a return signal is transmitted from the output unit 32 to the electromagnetic magnet 48. Thereby, the first electromagnetic unit 49 and the second electromagnetic unit 50 are attracted to each other, and the movable unit 40 is displaced to the separated position. Accordingly, the contact portion 37 is displaced in a direction in which the contact portion 37 is separated from the car guide rail 2. By the time the movable portion 40 reaches the separation position, the biasing direction of the disc spring 46 is reversed, and the movable portion 40 is held at the separation position. In this state, the car 3 is raised, and the pressing of the wedges 3 4 and the contact surface 45 against the car guide rail 2 is released.
このようなエレベータ装置では、 実施の形態 1と同様の効果を奏するとともに、 かご 3の速度を検出するためにかご速度センサ 3 1が昇降路 1内に設けられてい るので、 調速機及びガパナロープを用いる必要がなくなり、 エレベータ装置全体 の据付スペースを小さくすることができる。 In such an elevator apparatus, the same effect as that of the first embodiment is obtained, and a car speed sensor 31 is provided in the hoistway 1 to detect the speed of the car 3. Therefore, there is no need to use a governor and a governor rope, and the installation space of the entire elevator apparatus can be reduced.
また、 ァクチユエータ部 3 5は、 かごガイドレール 2に接離可能な接触部 3 7 と、 かごガイドレール 2に接離する方向へ接触部 3 7を変位させる作動機構 3 8 とを有しているので、 接触部 3 7の重量を楔 3 4よりも軽くすることにより、 作 動機構 3 8の接触部 3 7に対する駆動力を小さくすることができ、.作動機構 3 8 を小形化することができる。 さらに、 接触部 3 7を軽量にすることャ、 接触部 3 7の変位速度も大きくすることができ、 制動力の発生までに要する時間を短縮す ることができる。  Further, the actuator section 35 has a contact section 37 that can be brought into contact with and separated from the car guide rail 2 and an operating mechanism 38 that displaces the contact section 37 in a direction that comes into contact with and separates from the car guide rail 2. Therefore, by making the weight of the contact portion 37 lighter than that of the wedge 34, the driving force of the operating mechanism 38 on the contact portion 37 can be reduced, and the operating mechanism 38 can be downsized. it can. Furthermore, the weight of the contact portion 37 can be reduced, the displacement speed of the contact portion 37 can be increased, and the time required for generation of the braking force can be reduced.
また、 駆動部 4 1は、 可動部 4 0を接触位置及び開離位置で保持する皿ばね 4 6と、 通電により可動部 4 0を変位させる電磁マグネット 4 8とを有しているの で、 可動部 4 0の変位時のみの電磁マグネット 4 8への通電で可動部 4 0を接触 位置あるいは開離位置に確実に保持することができる。 実施の形態 3 .  In addition, since the drive unit 41 has a disc spring 46 that holds the movable unit 40 at the contact position and the separation position, and an electromagnetic magnet 48 that displaces the movable unit 40 when energized, The energization of the electromagnetic magnet 48 only when the movable part 40 is displaced allows the movable part 40 to be reliably held at the contact position or the separation position.

出力部 1 1 4には、 非常止め装置 3 3、 制御盤 1 0 2、 卷上機用ブレーキ装置 The output section 114 has an emergency stop device 33, a control panel 102, a hoisting machine
1 0 6、 検出手段 1 1 2及び記憶部 1 1 3がそれぞれ電気的に接続されている。 また、 出力部 1 1 4には、 かご位置センサ 1 0 9からの位置検出信号が、 かご速 度センサ 1 1 0からの速度検出信号が、 かご加速度センサ 1 1 1からの加速度検 出信号がそれぞれ経時的に継続して入力される。 出力部 1 1 4では、 位置検出信 号の入力に基づいてかご 3の位置が算出され、 また速度検出信号及ぴ加速度検出 信号のそれぞれの入力に基づいて、 かご 3の速度及ぴかご 3の加速度が複数種106, the detecting means 112 and the storage part 113 are electrically connected to each other. The output section 114 receives a position detection signal from the car position sensor 109, a speed detection signal from the car speed sensor 110, and an acceleration detection signal from the car acceleration sensor 111. Each is continuously input over time. The output unit 114 calculates the position of the car 3 based on the input of the position detection signal, and the speed of the car 3 and the speed of the car 3 based on the input of the speed detection signal and the acceleration detection signal. Multiple types of acceleration
(この例では 2種) の異常判断要素としてそれぞれ算出される。 (Two types in this example) are calculated as the abnormality determination factors.
出力部 1 1 4は、 かご 3の速度が第 1異常速度検出パターン 1 1 6を超えたと き、 あるいはかご 3の加速度が第 1異常加速度検出パターン 1 1 9を超えたとき に、 卷上機用ブレーキ装置 1 0 4へ作動信号 (トリガ信号) を出力するように なっている。 また、 出力部 1 1 4は、 卷上機用ブレーキ装置 1 0 4への作動信号 の出力と同時に、 卷上機 1 0 1の駆動を停止させるための停止信号を制御盤 1 0 2へ出力するようになっている。 さらに、 出力部 1 1 4は、 かご 3の速度が第 2 異常速度検出パターン 1 1 7を超えたとき、 あるいはかご 3の加速度が第 2異常 加速度検出パターン 1 2 0を超えたときに、 巻上機用ブレーキ装置 1 0 4及び非 常止め装置 3 3へ作動信号を出力するようになっている。 即ち、 出力部 1 1 4は、 かご 3の速度及び加速度の異常の程度に応じて、 作動信号を出力する制動手段を 決定するようになっている。 The output section 1 14 indicates that the speed of car 3 has exceeded the 1st abnormal speed detection pattern 1 16 Or when the acceleration of the car 3 exceeds the first abnormal acceleration detection pattern 1 19, an operation signal (trigger signal) is output to the hoisting machine brake device 104. The output unit 114 outputs a stop signal for stopping the drive of the hoisting machine 101 to the control panel 102 simultaneously with the output of the operation signal to the hoisting machine brake device 104. It is supposed to. Further, the output unit 114 outputs a signal when the speed of the car 3 exceeds the second abnormal speed detection pattern 1 17 or when the acceleration of the car 3 exceeds the second abnormal acceleration detection pattern 120. An operation signal is output to the upper machine brake device 104 and the emergency stop device 33. That is, the output unit 114 determines the braking means that outputs the operation signal according to the degree of abnormality in the speed and acceleration of the car 3.
他の構成は実施の形態 2と同様である。  Other configurations are the same as those of the second embodiment.
次に、 '動作について説明する。 かご位置センサ 1 0 9からの位置検出信号、 か ご速度センサ 1 1 0からの速度検出信号、 及ぴかご加速度センサ 1 1 1からのカロ 速度検出信号が出力部 1 1 4に入力されると、 出力部 1 1 4では、 各検出信号の 入力に基づいて、 かご 3の位置、 速度及び加速度が算出される。 この後、 出力部 1 1 4では、 記憶部 1 1 3からそれぞれ取得されたかご速度異常判断基準及びか ご加速度異常判断基準と、 各検出信号の入力に基づいて算出されたかご 3の速度 及び加速度とが比較され、 かご 3の速度及び加速度のそれぞれの異常の有無が検 出される。  Next, the operation will be described. When the position detection signal from the car position sensor 109, the speed detection signal from the car speed sensor 110, and the caro speed detection signal from the car acceleration sensor 111 are input to the output unit 114 The output unit 114 calculates the position, speed, and acceleration of the car 3 based on the input of each detection signal. After that, the output unit 114 outputs the car speed abnormality judgment criterion and the car acceleration abnormality judgment criterion respectively obtained from the storage unit 113, and the speed and the speed of the car 3 calculated based on the input of each detection signal. The acceleration and the acceleration are compared to detect whether or not each of the speed and the acceleration of the car 3 is abnormal.
通常運転時には、 かご 3の速度が通常速度検出パターンとほぼ同一の値となつ ており、 かご 3の加速度が通常加速度検出パターンとほぼ同一の値となっている ので、 出力部 1 1 4では、 かご 3の速度及び加速度のそれぞれに異常がないこと が検出され、 エレベータの通常運転が継続される。  During normal operation, the speed of car 3 has almost the same value as the normal speed detection pattern, and the acceleration of car 3 has almost the same value as the normal acceleration detection pattern. It is detected that there is no abnormality in the speed and acceleration of the car 3, and normal operation of the elevator is continued.
例えば、 何らかの原因で、 かご 3の速度が異常に上昇し第 1異常速度検出パ ターン 1 1 6を超えた場合には、 かご 3の速度に異常があることが出力部 1 1 4 で検出され、 作動信号が卷上機用ブレーキ装置 1 0 6へ、 停止信号が制御盤 1 0 2へ出力部 1 1 4からそれぞれ出力される。 これにより、 卷上機 1 0 1が停止さ れるとともに、 卷上機用ブレーキ装置 1 0 6が作動され、 駆動シーブ 1 0 4の回 転が制動される。 また、 かご 3の加速度が異常に上昇し第 1異常加速度設定値 1 1 9を超えた場 合にも、 作動信号及び停止信号が卷上機用ブレーキ装置 1 0 6及び制御盤 1 0 2 へ出力部 1 1 4からそれぞれ出力され、 駆動シーブ 1 0 4の回転が制動される。 卷上機用ブレーキ装置 1 0 6の作動後、 かご 3の速度がさらに上昇し第 2異常 速度設定値 1 1 7を超えた場合には、 卷上機用ブレーキ装置 1 0 6への作動信号 の出力を維持したまま、 出力部 1 1 4からは非常止め装置 3 3へ作動信号が出力 される。 これにより、 非常止め装置 3 3が作動され、 実施の形態 2と同様の動作 によりかご 3が制動される。 For example, if for some reason the speed of car 3 rises abnormally and exceeds the first abnormal speed detection pattern 1 16, the output section 1 14 detects that there is an abnormality in the speed of car 3. The operation signal is output from the output unit 114 to the hoisting machine brake device 106, and the stop signal is output to the control panel 102, respectively. As a result, the hoist 101 is stopped, the hoist braking device 106 is operated, and the rotation of the drive sheave 104 is braked. Also, when the acceleration of the car 3 abnormally increases and exceeds the first abnormal acceleration set value 1 19, the operation signal and the stop signal are transmitted to the hoisting machine brake device 106 and the control panel 102. The output is output from the output sections 114, respectively, and the rotation of the drive sheave 104 is braked. When the speed of the car 3 further increases after the operation of the hoist brake device 106 and exceeds the second abnormal speed set value 1 17, the operation signal to the hoist brake device 106 is provided. An output signal is output from the output section 114 to the safety device 33 while maintaining the output of. As a result, the emergency stop device 33 is operated, and the car 3 is braked by the same operation as in the second embodiment.
また、 卷上機用ブレーキ装置 1 0 6の作動後、 かご 3の加速度がさらに上昇し 第 2異常加速度設定値 1 2 0を超えた場合にも、 卷上機用ブレーキ装置 1 0 6へ の作動信号の出力を維持したまま、 出力部 1 1 4から非常止め装置 3 3へ作動信 号が出力され、 非常止め装置 3 3が作動される。  Also, when the acceleration of the car 3 further increases after the operation of the hoisting machine brake device 106 and exceeds the second abnormal acceleration set value 120, the braking of the hoisting machine brake device 106 is also performed. While maintaining the output of the operation signal, the operation signal is output from the output section 1 14 to the safety device 33, and the safety device 33 is operated.
このようなエレベータ装置では、 監視装置 1 0 8がエレベータの状態を検出す る検出手段 1 1 2からの情報に基づいてかご 3の速度及びかご 3の加速度を取得 し、 取得したかご 3の速度及ぴかご 3の加速度のうちいずれかの異常を判断した ときに卷上機用ブレーキ装置 1 0 6及び非常止め装置 3 3の少なくともいずれか に作動信号を出力するようになっているので、 監視装置 1 0 8によるエレベータ の異常の検知をより早期にかつより確実にすることができ、 エレベータの異常が 発生してからかご 3への制動力が発生するまでにかかる時間をより短くすること ができる。 即ち、 かご 3の速度及びかご 3の加速度という複数種の異常判断要素 の異常の有無が監視装置 1 0 8によりそれぞれ別個に判断されるので、 監視装置 1 0 8によるエレベータの異常の検知をより早期にかつより確実にすることがで き、 エレベータの異常が発生してからかご 3への制動力が発生するまでにかかる 時間を短くすることができる。  In such an elevator apparatus, the monitoring device 108 acquires the speed of the car 3 and the acceleration of the car 3 based on the information from the detecting means 112 for detecting the state of the elevator, and acquires the acquired speed of the car 3 When any of the accelerations of the car 3 is judged to be abnormal, an operation signal is output to at least one of the brake device 106 for the hoisting machine and the emergency stop device 33, so that monitoring is performed. The detection of an elevator abnormality by the device 108 can be performed earlier and more reliably, and the time required from the occurrence of the elevator abnormality to the generation of the braking force on the car 3 can be shortened. it can. In other words, the presence or absence of abnormality in a plurality of types of abnormality determination elements such as the speed of the car 3 and the acceleration of the car 3 is separately determined by the monitoring device 108, so that the detection of the elevator abnormality by the monitoring device 108 can be improved. As a result, the time required from the occurrence of an abnormality in the elevator to the generation of the braking force on the car 3 can be shortened.
また、 監視装置 1 0 8は、 かご 3の速度の異常の有無を判断するためのかご速 度異常判断基準、 及びかご 3の加速度の異常の有無を判断するためのかご加速度 異常判断基準が記憶されている記憶部 1 1 3を有しているので、 かご 3の速度及 び加速度のそれぞれの異常の有無の判断基準を容易に変更することができ、 エレ ベータの設計変更等にも容易に対応することができる。 また、 かご速度異常判断基準には、 通常速度検出パターン 1 1 5と、 通常速度 検出パターン 1 1 5よりも大きな値とされた第 1異常速度検出パターン 1 1 6と、 第 1異常速度検出パターン 1 1 6よりも大きな値とされた第 2異常速度検出パ ターン 1 1 7とが設定されており、 かご 3の速度が第 1異常速度検出パターン 1 1 6を超えたときに監視装置 1 0 8から卷上機用ブレーキ装置 1 0 6へ作動信号 が出力され、 かご 3の速度が第 2異常速度検出パターン 1 1 7を靖えたときに監 視装置 1 0 8から卷上機用ブレーキ装置 1 0 6及び非常止め装置 3 3へ作動信号 が出力されるようになっているので、 かご 3の速度の異常の大きさに応じてかご 3を段階的に制動することができる。 従って、 かご 3に大きな衝撃を与える頻度 を少なくすることができるとともに、 かご 3をより確実に停止させることができ る。 The monitoring device 108 also stores a car speed abnormality judgment criterion for judging the presence or absence of an abnormality in the speed of the car 3 and a car acceleration abnormality judgment criterion for judging the presence of an abnormality in the acceleration of the car 3. Since the storage unit 1 13 is used, it is possible to easily change the criteria for determining whether or not each of the speed and acceleration of the car 3 is abnormal, and to easily change the design of the elevator. Can respond. Also, the car speed abnormality determination criteria include a normal speed detection pattern 1 15, a first abnormal speed detection pattern 1 16 set to a value larger than the normal speed detection pattern 1 15, and a first abnormal speed detection pattern. The second abnormal speed detection pattern 1 17 which is set to a value larger than 1 16 is set, and the monitoring device 10 0 when the speed of the car 3 exceeds the first abnormal speed detection pattern 1 16 An operation signal is output from 8 to the brake device 106 for the hoisting machine, and when the speed of the car 3 reaches the second abnormal speed detection pattern 1 17 the monitoring device 10 8 Since an operation signal is output to 106 and the safety gear 33, the car 3 can be braked stepwise according to the magnitude of the speed abnormality of the car 3. Therefore, the frequency of applying a large impact to the car 3 can be reduced, and the car 3 can be stopped more reliably.
また、 'かご加速度異常判断基準には、 通常加速度検出パターン 1 1 8と、 通常 加速度検出パターン 1 1 8よりも大きな値とされた第 1異常加速度検出パターン In addition, the car acceleration abnormality determination criterion includes a normal acceleration detection pattern 1 18 and a first abnormal acceleration detection pattern having a value larger than the normal acceleration detection pattern 1 18.
1 1 9と、 第 1異常加速度検出パターン 1 1 9よりも大きな値とされた第 2異常 加速度検出パターン 1 2 0とが設定されており、 かご 3の加速度が第 1異常加速 度検出パターン 1 1 9を超えたときに監視装置 1 0 8から卷上機用ブレーキ装置1 1 9 and the 2nd abnormal acceleration detection pattern 1 20 which is set to a value larger than the 1st abnormal acceleration detection pattern 1 19 are set, and the acceleration of car 3 is set to the 1st abnormal acceleration detection pattern 1 Monitoring device when the load exceeds 1 9 Brake device for the winding machine from 108
1 0 6へ作動信号が出力され、 かご 3の加速度が第 2異常速度検出パターン 1 2An operation signal is output to 106, and the acceleration of car 3 is changed to the second abnormal speed detection pattern 1 2
0を超えたときに監視装置 1 0 8から巻上機用ブレーキ装置 1 0 6及び非常止め 装置 3 3へ作動信号が出力されるようになっているので、 かご 3の加速度の異常 の大きさに応じてかご 3を段階的に制動することができる。 通常、 かご 3の速度 に異常が発生する前にかご 3の加速度に異常が発生することから、 かご 3に大き な衝擊を与える頻度をさらに少なくすることができるとともに、 かご 3をさらに 確実に停止させることができる。 When 0 is exceeded, the operation signal is output from the monitoring device 108 to the hoisting machine brake device 106 and the emergency stop device 33, so the magnitude of the abnormal acceleration of the car 3 The car 3 can be braked gradually according to Usually, the acceleration of the car 3 occurs before the speed of the car 3 becomes abnormal, so that the frequency of applying a large impact to the car 3 can be further reduced, and the car 3 can be stopped more reliably. Can be done.
また、 通常速度検出パターン 1 1 5、 第 1異常速度検出パターン 1 1 6及び第 Also, the normal speed detection pattern 1 15, the 1st abnormal speed detection pattern 1 16
2異常速度検出パターン 1 1 7は、 かご 3の位置に対応して設定されているので、 第 1異常速度検出パターン 1 1 6及び第 2異常速度検出パターン 1 1 7のそれぞ れをかご 3の昇降区間のすべての位置で通常速度検出パターン 1 1 5に対応させ て設定することができる。 従って、 特に加減速区間では通常速度検出パターン 1(2) Since the abnormal speed detection pattern 1 17 is set corresponding to the position of the car 3, the first abnormal speed detection pattern 1 16 and the second abnormal speed detection pattern 1 17 Can be set to correspond to the normal speed detection pattern 1 15 at all positions in the vertical section. Therefore, especially in the acceleration / deceleration section, the normal speed detection pattern 1
1 5の値が小さいので、 第 1異常速度検出パターン 1 1 6及び第 2異常速度検出 パターン 1 1 7のそれぞれを比較的小さい値に設定することができ、 制動による かご 3への衝撃を小さくすることができる。 Since the value of 15 is small, the 1st abnormal speed detection pattern 1 16 and the 2nd abnormal speed detection Each of the patterns 1 17 can be set to a relatively small value, and the impact on the car 3 due to braking can be reduced.
なお、 上記の例では、 監視装置 1 0 8がかご 3の速度を取得するためにかご速 度センサ 1 1 0が用いられているが、 かご速度センサ 1 1 0を用いずに、 かご位 置センサ 1 0 9により検出されたかご 3の位置からかご 3の速度を導出してもよ い。 即ち、 かご位置センサ 1 0 9からの位置検出信号により算出きれたかご 3の 位置を微分することによりかご 3の速度を求めてもよい。  In the above example, the car speed sensor 110 is used by the monitoring device 108 to obtain the speed of the car 3, but the car position sensor is used without using the car speed sensor 110. The speed of the car 3 may be derived from the position of the car 3 detected by the sensor 109. That is, the speed of the car 3 may be obtained by differentiating the position of the car 3 calculated based on the position detection signal from the car position sensor 109.
また、 上記の例では、 監視装置 1 0 8がかご 3の加速度を取得するためにかご 加速度センサ 1 1 1が用いられているが、 かご加速度センサ 1 1 1を用いずに、 かご位置センサ 1 0 9により検出されたかご 3の位置からかご 3の加速度を導出 してもよい。 即ち、 かご位置センサ 1 0 9からの位置検出信号により算出された かご 3の位置を 2回微分することによりかご 3の加速度を求めてもよい。  Also, in the above example, the car acceleration sensor 111 is used by the monitoring device 108 to acquire the acceleration of the car 3, but the car position sensor 1 11 is used without using the car acceleration sensor 111. The acceleration of the car 3 may be derived from the position of the car 3 detected by 09. That is, the acceleration of the car 3 may be obtained by differentiating the position of the car 3 calculated by the position detection signal from the car position sensor 109 twice.

他の構成は実施の形態 1 1と同様である。  Other configurations are the same as those of the eleventh embodiment.
次に、 動作について説明する。 かご位置センサ 1 0 9からの位置検出信号、 力 ご速度センサ 1 1 0からの速度検出信号、 及び各ロープセンサ 1 3 1からの破断 検出信号が出力部 1 1 4に入力されると、 出力部 1 1 4では、 各検出信号の入力 に基づいて、 かご 3の位置、 かご 3の速度及び主ロープ 4の破断本数が算出され る。 この後、 出力部 1 1 4では、 記憶部 1 1 3からそれぞれ取得されたかご速度 異常判断基準及びロープ異常判断基準と、 各検出信号の入力に基づいて算出され たかご 3の速度及び主ロープ 4の破断本数とが比較され、 かご 3の速度及び主 ロープ 4の状態のそれぞれの異常の有無が検出される。 Next, the operation will be described. When the position detection signal from the car position sensor 109, the speed detection signal from the car speed sensor 110, and the break detection signal from each rope sensor 131 are input to the output unit 114, output In the section 114, the position of the car 3, the speed of the car 3, and the number of breaks of the main rope 4 are calculated based on the input of each detection signal. Thereafter, the output unit 114 calculates the speed based on the car speed abnormality criterion and the rope abnormality criterion obtained from the storage unit 113 and the input of each detection signal. The speed of the car 3 and the number of broken main ropes 4 are compared, and the presence or absence of abnormality in the speed of the car 3 and the state of the main rope 4 is detected.
通常運転時には、 かご 3の速度が通常速度検出パターンとほぼ同一の値となつ ており、 主ロープ 4の破断本数がゼロであるので、 出力部 1 1 4では、 かご 3の 速度及ぴ主ロープ 4の状態のそれぞれに異常がないことが検出され、 ェレベータ の通常運転が継続される。  During normal operation, the speed of car 3 has almost the same value as the normal speed detection pattern, and the number of breaks in main rope 4 is zero. It is detected that there is no abnormality in each of the conditions 4 and normal operation of the elevator is continued.
例えば、 何らかの原因で、 かご 3の速度が異常に上昇し第 1異常速度検出パ ターン 1 1 6 (図 1 9 ) を超えた場合には、 かご 3の速度に異常があることが出 力部 1 1 4で検出され、 作動信号が巻上機用ブレーキ装置 1 0 6へ、 停止信号が 制御盤 1 0 2へ出力部 1 1 4からそれぞれ出力される。 これにより、 卷上機 1 0 1が停止されるとともに、 卷上機用ブレーキ装置 1 0 6が作動され、 駆動シーブ 1 0 4の回転が制動される。  For example, if for some reason the speed of car 3 rises abnormally and exceeds the first abnormal speed detection pattern 1 16 (Fig. 19), the output section will indicate that the speed of car 3 is abnormal. The operation signal is detected by 114 and the operation signal is output from the output unit 114 to the brake device 106 for the hoist, and the stop signal is output to the control panel 102. As a result, the hoisting machine 101 is stopped, the hoisting machine brake device 106 is operated, and the rotation of the drive sheave 104 is braked.
また、 少なくとも 1本の主ロープ 4が破断した場合にも、 作動信号及ぴ停止信 号が卷上機用ブレーキ装置 1 0 6及び制御盤 1 0 2へ出力部 1 1 4からそれぞれ 出力され、 駆動シーブ 1 0 4の回転が制動される。  In addition, even when at least one main rope 4 is broken, an operation signal and a stop signal are output from the output unit 114 to the hoisting machine brake device 106 and the control panel 102, respectively. The rotation of the drive sheave 104 is braked.
巻上機用ブレーキ装置 1 0 6の作動後、 かご 3の速度がさらに上昇し第 2異常 速度設定値 1 1 7 (図 1 9 ) を超えた場合には、 卷上機用ブレーキ装置 1 0 6 へ の作動信号の出力を維持したまま、 出力部 1 1 4からは非常止め装置 3 3へ作動 信号が出力される。 これにより、 非常止め装置 3 3が作動され、 実施の形態 2と 同様の動作によりかご 3が制動される。  If the speed of the car 3 further rises after the operation of the brake device 106 for the hoisting machine and exceeds the second abnormal speed set value 1 17 (Fig. 19), the brake device 10 10 for the hoisting machine While the output of the operation signal to 6 is maintained, the operation signal is output to the safety gear 33 from the output section 114. As a result, the emergency stop device 33 is actuated, and the car 3 is braked by the same operation as in the second embodiment.
また、 卷上機用ブレーキ装置 1 0 6の作動後、 すべての主ロープ 4が破断した 場合にも、 巻上機用ブレーキ装置 1 0 6への作動信号の出力を維持したまま、 出 力部 1 1 4から非常止め装置 3 3へ作動信号が出力され、 非常止め装置 3 3が作 動さ;^る。  In addition, even if all the main ropes 4 are broken after the operation of the hoisting machine brake device 106, the output section is maintained while maintaining the output of the operating signal to the hoisting machine brake device 106. An operation signal is output from 1 1 4 to the safety gear 3 3, and the safety gear 3 3 is activated.
このようなエレベータ装置では、 監視装置 1 0 8がエレベータの状態を検出す る検出手段 1 1 2からの情報に基づいてかご 3の速度及び主ロープ 4の状態を取 得し、 取得したかご 3の速度及ぴ主ロープ 4の状態のうちいずれかに異常がある と判断したときに卷上機用ブレーキ装置 1 0 6及び非常止め装置 3 3の少なくと もいずれかに作動信号を出力するようになっているので、 異常の検出対象数が多 くなり、 かご 3の速度の異常だけでなく主ロープ 4の状態の異常も検出すること ができ、 監視装置 1 0 8によるエレベータの異常の検知をより皁期にかつより確 実にすることができる。 従って、 エレベータの異常が発生してからかご 3への制 動力が発生するまでにかかる時間をより短くすることができる。 In such an elevator device, the monitoring device 108 acquires the speed of the car 3 and the state of the main rope 4 based on information from the detecting means 112 for detecting the condition of the elevator, and the acquired car 3 When it is determined that any of the speed of the main rope 4 and the state of the main rope 4 are abnormal, an operation signal is output to at least one of the brake device 106 for the hoisting machine and the emergency stop device 33. , The number of targets for abnormality detection is large. It becomes possible to detect not only abnormalities in the speed of the car 3 but also abnormalities in the state of the main ropes 4, making it possible to more quickly and more reliably detect elevator abnormalities by the monitoring device 108. .

他の構成は実施の形態 1 1と同様である。  Other configurations are the same as those of the eleventh embodiment.
次に、 動作について説明する。 かご位置センサ 1 0 9からの位 S検出信号、 か ご速度センサ 1 1 0からの速度検出信号、 及びドアセンサ 1 4 0からの戸閉検出 信号が出力部 1 1 4に入力されると、 出力部 1 1 4では、 各検出信号の入力に基 づいて、 かご 3の位置、 かご 3の速度及びかご出入口 2 6の状態が算出される。 この後、 出力部 1 1 4では、 記憶部 1 1 3からそれぞれ取得されたかご速度異常 判断基準及び出入口異常判断基準と、 各検出信号の入力に基づいて算出されたか ご 3の速度及ぴ各かごドア 2 8の状態とが比較され、 かご 3の速度及ぴかご出入 口 2 6の状態のそれぞれの異常の有無が検出される。  Next, the operation will be described. When the position S detection signal from the car position sensor 109, the speed detection signal from the car speed sensor 110, and the door closing detection signal from the door sensor 140 are input to the output unit 114, output In the section 114, the position of the car 3, the speed of the car 3, and the state of the car entrance 26 are calculated based on the input of each detection signal. After that, the output unit 114 outputs the car speed abnormality judgment criterion and the entrance / exit abnormality judgment criterion respectively obtained from the storage unit 113, and the speed and the like of the car 3 calculated based on the input of each detection signal. The state of the car door 28 is compared with the speed of the car 3 and the presence or absence of an abnormality in the state of the car 3 and the state of the car entrance 26 is detected.
通常運転時には、 かご 3の速度が通常速度検出パターンとほぼ同一の値となつ ており、 かご 3が昇降している際のかご出入口 2 6は戸閉状態であるので、 出力 部 1 1 4では、 かご 3の速度及びかご出入口 2 6の状態のそれぞれに異常がない ことが検出され、 ェレベータの通常運転が継続される。  During normal operation, the speed of car 3 has almost the same value as the normal speed detection pattern, and car entrance 26 when car 3 is moving up and down is closed. It is detected that there is no abnormality in each of the speed of the car 3 and the state of the car entrance 26, and the normal operation of the elevator is continued.
例えば、 何らかの原因で、 かご 3の速度が異常に上昇し第 1異常速度検出パ ターン 1 1 6 (図 1 9 ) を超えた場合には、 かご 3の速度に異常があることが出 力部 1 1 4で検出され、 作動信号が卷上機用ブレーキ装置 1 0 6へ、 停止信号が 制御盤 1 0 2へ出力部 1 1 4からそれぞれ出力される。 これにより、 卷上機 1 0 1が停止されるとともに、 卷上機用ブレーキ装置 1 0 6が作動され、 駆動シーブ 1 0 4の回転が制動される。  For example, if for some reason the speed of car 3 rises abnormally and exceeds the first abnormal speed detection pattern 1 16 (Fig. 19), the output section will indicate that the speed of car 3 is abnormal. Detected by 114, the operation signal is output from the output unit 114 to the hoisting machine brake device 106, and the stop signal is output to the control panel 102. As a result, the hoisting machine 101 is stopped, the hoisting machine brake device 106 is operated, and the rotation of the drive sheave 104 is braked.
また、 かご 3が昇降されている際のかご出入口 2 6が戸閉されていない状態と なっている場合にも、 かご出入口 2 6の異常が出力部 1 1 4で検出され、 作動信 号及び停止信号が卷上機用ブレーキ装置 1 0 6及び制御盤 1 0 2へ出力部 1 1 4 からそれぞれ出力され、 駆動シーブ 1 0 4の回転が制動される。  In addition, even when the car entrance 26 is not closed when the car 3 is raised and lowered, the abnormality of the car entrance 26 is detected by the output section 114, and the operation signal and A stop signal is output from the output unit 114 to the hoisting machine brake device 106 and the control panel 102, respectively, and the rotation of the drive sheave 104 is braked.
卷上機用ブレーキ装置 1 0 6の作動後、 かご 3の速度がさらに上昇し第 2異常 速度設定値 1 1 7 (図 1 9 ) を超えた場合には、 卷上機用ブレーキ装置 1 0 6へ の作動信号の出力を維持したまま、 出力部 1 1 4からは非常止め装置 3 3へ作動 信号が出力される。 これにより、 非常止め装置 3 3が作動され、 実施の形態 2と 同様の動作によりかご 3が制動される。 If the speed of the car 3 further increases after the operation of the hoisting machine brake device 106 and exceeds the second abnormal speed set value 1 17 (Fig. 19), the hoisting machine brake device 10 To 6 While the output of the operation signal is maintained, the operation signal is output from the output section 114 to the safety device 33. As a result, the emergency stop device 33 is actuated, and the car 3 is braked by the same operation as in the second embodiment.
このようなエレベータ装置では、 監視装置 1 0 8がエレベータの状態を検出す る検出手段 1 1 2からの情報に基づいてかご 3の速度及びかご出入口 2 6の状態 を取得し、 取得したかご 3の速度及ぴかご出入口 2 6の状態のうちいずれかに異 常があると判断したときに巻上機用ブレーキ装置 1 0 6及び非常止め装置 3 3の 少なくともいずれかに作動信号を出力するようになっているので、 エレベータの 異常の検出対象数が多くなり、 かご 3の速度の異常だけでなくかご出入口 2 6の 状態の異常も検出することができ、 監視装置 1 0 8によるエレベータの異常の検 知をより早期にかつより確実にすることができる。 従って、 エレベータの異常が 発生してからかご 3への制動力が発生するまでにかかる時間をより短くすること ができる。  In such an elevator device, the monitoring device 108 acquires the speed of the car 3 and the condition of the car entrance 26 based on the information from the detecting means 112 detecting the condition of the elevator, and the acquired car 3 When it is determined that any of the speed of the car and the state of the car entrance 26 is abnormal, an operation signal is output to at least one of the brake device 106 for the hoisting machine and the emergency stop device 33. , The number of objects to be detected for elevator abnormalities increases, and it is possible to detect not only abnormalities in the speed of car 3 but also abnormalities in the status of car entrance 26 and elevator abnormalities by monitoring device 108. Can be detected earlier and more reliably. Therefore, it is possible to further reduce the time required from the occurrence of an elevator abnormality to the generation of the braking force on the car 3.
なお、 上記の例では、 かご出入口 2 6の状態のみがドアセンサ 1 4 0により検 出されるようになっているが、 かご出入口 2 6及び乗場出入口 1 4 1のそれぞれ の状態をドアセンサ 1 4 0により検出するようにしてもよい。 この場合、 各乗場 ドア 1 4 2の戸閉位置への変位が、 各かごドア 2 8の戸閉位置への変位とともに ドアセンサ 1 4 0により検出される。 このようにすれば、 例えばかごドア 2 8と 乗場ドア 1 4 2とを互いに係合させる係合装置等が故障して、 かごドア 2 8のみ が変位される場合にも、 エレベータの異常を検出することができる。 実施の形態 1 6 .  In the above example, only the state of the car doorway 26 is detected by the door sensor 140, but the respective states of the car doorway 26 and the landing doorway 141 are detected by the door sensor 140. You may make it detect. In this case, the displacement of each landing door 142 to the door closed position is detected by the door sensor 140 together with the displacement of each car door 28 to the door closed position. In this way, an abnormality in the elevator is detected even when, for example, the car door 28 is displaced due to a failure of an engagement device for engaging the car door 28 and the landing door 142 with each other. can do.

Drive power is supplied to the hoisting machine 101 through the power supply cable 150 under the control of the control panel 102.
電力供給ケーブル 1 5 0には、 電力供給ケーブル 1 5 0を流れる電流を測定す ることにより卷上機 1 0 1の状態を検出する駆動装置検出部である電流センサ 1 5 1が設置されている。 電流センサ 1 5 1は、 電力供給ケーブル 1 5 0の電流値 に対応した電流検出信号 (駆動装置状態検出信号) を出力部 1 1 4へ出力するよ うになつている。 なお、 電流センサ 1 5 1は、 昇降路 1上部に配置されている。 また、 電流センサ 1 5 1としては、 電力供給ケーブル 1 5 0を流れる電流の大き さに応じて発生する誘導電流を測定する変流器 (C T ) 等が挙げられる。 The power supply cable 150 includes a current sensor 1 serving as a driving device detecting unit that detects a state of the hoisting machine 101 by measuring a current flowing through the power supply cable 150. 5 1 is installed. The current sensor 151 outputs a current detection signal (drive device state detection signal) corresponding to the current value of the power supply cable 150 to the output unit 114. Note that the current sensor 15 1 is arranged above the hoistway 1. Further, as the current sensor 151, a current transformer (CT) for measuring an induced current generated according to the magnitude of the current flowing through the power supply cable 150, or the like can be given.
出力部 1 1 4には、 かご位置センサ 1 0 9と、 かご速度センサ 1. 1 0と、 電流 センサ 1 5 1とがそれぞれ電気的に接続されている。 なお、 検出手段 1 1 2は、 かご位置センサ 1 0 9、 かご速度センサ 1 1 0及び電流センサ 1 5 1を有してい る。  A car position sensor 1109, a car speed sensor 1.10, and a current sensor 151 are electrically connected to the output section 114. The detecting means 112 has a car position sensor 109, a car speed sensor 110 and a current sensor 151.
記憶部 1 1 3には、 図 1 9に示すような実施の形態 1 1と同様のかご速度異常 判断基準と、 巻上機 1 0 1の状態についての異常の有無を判断する基準である駆 動装置異 '常判断基準とが記憶されている。  The storage unit 113 stores the same car speed abnormality determination criterion as in the embodiment 11 as shown in FIG. 19 and a drive criterion for determining whether there is an abnormality in the state of the hoisting machine 101. The moving device abnormal judgment criterion is stored.
駆動装置異常判断基準には、 3段階の検出パターンが設定されている。 即ち、 駆動装置異常判断基準には、 通常運転時に電力供給ケーブル 1 5 0を流れる電流 値である通常レベルと、 通常レベルよりも大きな値とされた第 1異常レベルと、 第 1異常レベルよりも大きな値とされた第 2異常レベルとが設定されている。 出力部 1 1 4では、 位置検出信号の入力に基づいてかご 3の位置が算出され、 また速度検出信号及び電流検出信号のそれぞれの入力に基づいて、 かご 3の速度 及ぴ卷上機 1 0 1の状態が複数種 (この例では 2種) の異常判断要素としてそれ ぞれ算出される。  The drive device abnormality determination criterion has three stages of detection patterns. That is, the drive device abnormality determination criteria include a normal level which is a current value flowing through the power supply cable 150 during normal operation, a first abnormal level which is larger than the normal level, and a first abnormal level which is larger than the first abnormal level. The second abnormal level is set to a large value. The output unit 114 calculates the position of the car 3 based on the input of the position detection signal, and the speed of the car 3 and the winding machine 10 based on the respective input of the speed detection signal and the current detection signal. The state of 1 is calculated as each of multiple (two in this example) abnormality judgment factors.
出力部 1 1 4は、 かご 3の速度が第 1異常速度検出パターン 1 1 6 (図 1 9 ) を超えたとき、 あるいは電力供給ケーブル 1 5 0を流れる電流の大きさが駆動装 置異常判断基準における第 1異常レベルの値を超えたときに、 卷上機用ブレーキ 装置 1 0 4へ作動信号 (トリガ信号) を出力するようになっている。 また、 出力 部 1 1 4は、 かご 3の速度が第 2異常速度検出パターン 1 1 7 (図 1 9 ) を超え たとき、 あるいは電力供給ケーブル 1 5 0を流れる電流の大きさが駆動装置異常 判断基準における第 2異常レベルの値を超えたときに、 卷上機用ブレーキ装置 1 The output unit 114 determines whether the drive unit is abnormal when the speed of the car 3 exceeds the first abnormal speed detection pattern 1 16 (Fig. 19) or the magnitude of the current flowing through the power supply cable 150. When the value exceeds the value of the first abnormal level in the reference, an operation signal (trigger signal) is output to the brake device 104 for the hoisting machine. In addition, the output unit 114 detects when the speed of the car 3 exceeds the second abnormal speed detection pattern 1 17 (FIG. 19) or when the magnitude of the current flowing through the power supply cable 150 is When the value of the second abnormal level in the criterion is exceeded, a brake device 1

That is, the output unit 114 responds to the degree of abnormality of the speed of the car 3 and the state of the hoist 101, respectively. Then, the braking means for outputting the operation signal is determined.
他の構成は実施の形態 1 1と同様である。  Other configurations are the same as those of the eleventh embodiment.
次に、 動作について説明する。 かご位置センサ 1 0 9からの位置検出信号、 か ご速度センサ 1 1 0からの速度検出信号、 及ぴ電流センサ 1 5 1からの電流検出 信号が出力部 1 1 4に入力されると、 出力部 1 1 4では、 各検出信号の入力に基 づいて、 かご 3の位置、 かご 3の速度及び電力供給ケーブル 1 5 0内の電流の大 きさが算出される。 この後、 出力部 1 1 4では、 記憶部 1 1 3からそれぞれ取得 されたかご速度異常判断基準及び駆動装置状態異常判断基準と、 各検出信号の入 力に基づいて算出されたかご 3の速度及び電力供給ケーブル 1 5 0内の電流の大 きさとが比較され、 かご 3の速度及ぴ卷上機 1 0 1の状態のそれぞれの異常の有 無が検出される。  Next, the operation will be described. When the position detection signal from the car position sensor 109, the speed detection signal from the car speed sensor 110, and the current detection signal from the current sensor 151 are input to the output section 114, the output In the unit 114, the position of the car 3, the speed of the car 3, and the magnitude of the current in the power supply cable 150 are calculated based on the input of each detection signal. After that, the output unit 114 outputs the speed of the car 3 calculated based on the input of the detection signal and the car speed abnormality judgment criterion and the drive device abnormality judgment criterion respectively obtained from the storage unit 113. The magnitude of the current in the power supply cable 150 is compared with the magnitude of the current in the power supply cable 150, and the presence or absence of abnormality in each of the speed of the car 3 and the state of the winder 101 is detected.
通常運転時には、 かご 3の速度が通常速度検出パターン 1 1 5 (図 1 9 ) とほ ぼ同一の値となっており、 電力供給ケーブル 1 5 0を流れる電流の大きさが通常 レベルであるので、 出力部 1 1 4では、 かご 3の速度及ぴ卷上機 1 0 1の状態の それぞれに異常がないことが検出され、 ェレベータの通常運転が継続される。 例えば、 何らかの原因で、 かご 3の速度が異常に上昇し第 1異常速度検出パ ターン 1 1 6 (図 1 9 ) を超えた場合には、 かご 3の速度に異常があることが出 力部 1 1 4で検出され、 作動信号が卷上機用ブレーキ装置 1 0 6へ、 停止信号が 制御盤 1 0 2へ出力部 1 1 4からそれぞれ出力される。 これにより、 卷上機 1 0 1が停止されるとともに、 卷上機用ブレーキ装置 1 0 6が作動され、 駆動シープ 1 0 4の回転が制動される。  During normal operation, the speed of the car 3 is almost the same as the normal speed detection pattern 1 15 (Fig. 19), and the current flowing through the power supply cable 150 is at the normal level. The output unit 114 detects that there is no abnormality in the speed of the car 3 and the state of the winding machine 101, respectively, and normal operation of the elevator is continued. For example, if for some reason the speed of car 3 rises abnormally and exceeds the first abnormal speed detection pattern 1 16 (Fig. 19), the output section will indicate that the speed of car 3 is abnormal. Detected by 114, the operation signal is output from the output unit 114 to the hoisting machine brake device 106, and the stop signal is output to the control panel 102. As a result, the hoist 101 is stopped, the brake device 106 for the hoist is operated, and the rotation of the drive sheave 104 is braked.
また、 電力供給ケーブル 1 5 0を流れる電流の大きさが駆動装置状態異常判断 基準における第 1異常レベルを超えた場合にも、 作動信号及び停止信号が卷上機 用ブレーキ装置 1 0 6及び制御盤 1 0 2へ出力部 1 1 4からそれぞれ出力され、 駆動シーブ 1 0 4の回転が制動される。  Also, when the magnitude of the current flowing through the power supply cable 150 exceeds the first abnormal level in the drive device state abnormality determination criterion, the operation signal and the stop signal are transmitted to the hoisting machine brake device 106 and the control unit. The output is output from the output unit 114 to the panel 102, and the rotation of the drive sheave 104 is braked.
卷上機用ブレーキ装置 1 0 6の作動後、 かご 3の速度がさらに上昇し第 2異常 速度設定値 1 1 7 (図 1 9 ) を超えた場合には、 卷上機用ブレーキ装置 1 0 6へ の作動信号の出力を維持したまま、 出力部 1 1 4からは非常止め装置 3 3へ作動 信号が出力される。 これにより、 非常止め装置 3 3が作動され、 実施の形態 2と 同様の動作によりかご 3が制動される。 If the speed of the car 3 further increases after the operation of the hoisting machine brake device 106 and exceeds the second abnormal speed set value 1 17 (Fig. 19), the hoisting machine brake device 10 While maintaining the output of the operation signal to 6, the operation signal is output to the safety gear 33 from the output section 114. As a result, the emergency stop device 33 is operated, and the second embodiment differs from the second embodiment. Car 3 is braked by the same operation.
また、 卷上機用ブレーキ装置 1 0 6の作動後、 電力供給ケーブル 1 5 0を流れ る電流の大きさが駆動装置状態異常判断基準における第 2異常レベルを超えた場 合にも、 卷上機用ブレーキ装置 1 0 6への作動信号の出力を維持したまま、 出力 部 1 1 4から非常止め装置 3 3へ作動信号が出力され、 非常止め装置 3 3が作動 さ Lる。  Also, if the magnitude of the current flowing through the power supply cable 150 after the operation of the hoisting machine brake device 106 exceeds the second abnormal level in the drive device abnormality abnormality criterion, the hoisting operation is also performed. While maintaining the output of the operation signal to the machine brake device 106, the operation signal is output from the output unit 114 to the safety device 33, and the safety device 33 is activated.

When it is determined that there is an abnormality in any of the speed of the car 3 and the state of the hoist 101, at least one of the brake device 106 for the hoist and the emergency stop device 33 is required. Since an operation signal is output, the number of elevator abnormality detection targets increases, and the time required from the occurrence of an elevator abnormality to the generation of braking force on car 3 can be shortened. it can.
なお、 上記の例では、 電力供給ケーブル 1 5 0を流れる電流の大きさを測定す る電流センサ 1 5 1を用いて卷上機 1 0 1の状態を検出するようになっている力 巻上機 1 0 1の温度を測定する温度センサを用いて卷上機 1 0 1の状態を検出す るようにしてもよい。  Note that, in the above example, the current hoist is configured to detect the state of the hoisting machine 101 by using the current sensor 151 that measures the magnitude of the current flowing through the power supply cable 150. The state of the hoist 101 may be detected using a temperature sensor that measures the temperature of the machine 101.
また、 上記実施の形態 1 1〜1 6では、 出力部 1 1 4は、 非常止め装置 3 3へ 作動信号を出力する前に、 卷上機用ブレーキ装置 1 0 6へ作動信号を出力するよ うになつているが、 かご 3に非常止め装置 3 3とは別個に搭載され、 かごガイド レール 2を挟むことによりかご 3を制動するかごブレーキ、 釣合おもり 1 0 7に 搭載され、 釣合おもり 1 0 7を案内する釣合おもりガイドレールを挟むことによ り釣合おもり 1 0 7を制動する釣合おもりブレーキ、 あるいは昇降路 1内に設け られ、 主ロープ 4を拘束することにより主ロープ 4を制動するロープブレーキへ 出力部 1 1 4に作動信号を出力させるようにしてもよい。  In Embodiments 11 to 16 described above, the output unit 114 outputs the operation signal to the hoisting machine brake device 106 before outputting the operation signal to the emergency stop device 33. Although it is undulating, it is mounted separately from the safety device 3 on the car 3, a car brake that brakes the car 3 by sandwiching the car guide rail 2, mounted on the counterweight 107, and a counterweight A counterweight that guides 107 A counterweight brake that sandwiches the guide rail, or a counterweight brake that brakes 107, or a main rope that is provided in the hoistway 1 and restrains the main rope 4 An output signal may be output to the output unit 1 14 to the rope brake that brakes 4.
また、 上記実施の形態 1〜1 6では、 出力部から非常止め装置への電力供給の ための伝送手段として、 電気ケーブルが用いられているが、 出力部に設けられた 発信器と非常止め機構に設けられた受信器とを有する無線通信装置を用いてもよ い。 また、 光信号を伝送する光ファイバケーブルを用いてもよい。 また、 上記実施の形態 1〜 1 6では、 非常止め装置は、 かごの下方向への過速 度 (移動) に対して制動するようになっているが、 この非常止め装置が上下逆に されたものをかごに装着して、 上方向への過速度 (移動) に対して制動するよう にしてもよい。 . 実施の形態 1 7 . In Embodiments 1 to 16, the electric cable is used as the transmission means for supplying power from the output unit to the safety gear. However, the transmitter provided in the output unit and the safety gear mechanism are provided. Alternatively, a wireless communication device having a receiver provided in the device may be used.

図 3 2は図 3 1のかご振動検出器 2 1 7の近傍を拡大して示す正面図、 図 3 3 は図 3 2のかご振動検出器 2 1 7の近傍を示す側面図である。 図において、 各か ご側端部 2 0 8 aには、 シャックル口ッド 2 2 1が接続されている。 各シャック ルロッド '2 2 1は、 ロープ端支持部 2 1 9 aを貫通している。  FIG. 32 is an enlarged front view showing the vicinity of the car vibration detector 2 17 of FIG. 31. FIG. 33 is a side view showing the vicinity of the car vibration detector 2 17 of FIG. In the figure, a shackle opening 2 221 is connected to each car side end 208 a.

各シャツクルロッド 2 2 1の上端部には、 上部ばね受け 2 2 2が取り付けられ ている。 各上部ばね受け 2 2 2とロープ端支持部 2 1 9 aとの間には、 ばね (弹 性体) 2 2 3が介在されている。  An upper spring receiver 222 is attached to the upper end of each shirtcle rod 222. A spring (flexible body) 223 is interposed between each upper spring receiver 222 and the rope end support 219a.
また、 各シャックノレ口ッド 2 2 1の上端部には、 取付部材 2 2 4が取り付けら れている。 取付部材 2 2 4のうちの 1つの上端部には、 かご振動検出器 2 1 7が 搭載されている。  In addition, an attachment member 224 is attached to the upper end of each shackle socket 221. At an upper end of one of the mounting members 224, a car vibration detector 217 is mounted.
次に、 動作について説明する。 乗客によるいたずら等によりかご 2 0 1に揺れ が生じると、 そのかご揺れが主ロープ 2 1 3を介してかご振動検出器 2 1 7に伝 達される。 かご振動検出器 2 1 7は、 上下方向の振動に応じた電圧信号を発生す る。 かご振動検出器 2 1 7で発生した電圧信号は、 いたずら検出部 2 1 8に送ら 。  Next, the operation will be described. When the car 201 shakes due to mischief by a passenger or the like, the car shake is transmitted to the car vibration detector 2 17 via the main rope 2 13. The car vibration detector 2 17 generates a voltage signal according to the vertical vibration. The voltage signal generated by the car vibration detector 217 is sent to the tamper detector 218.
いたずら検出部 2 1 8では、 入力された電圧信号が予め設定された基準値と比 較され、 かご揺れの程度がエレベータ制御部 2 1 6による過速度検出に影響を与 えるレベルであるかどうかが判断される。  The tamper detection unit 218 compares the input voltage signal with a preset reference value, and determines whether the degree of car swing is at a level that affects the overspeed detection by the elevator control unit 216. Is determined.
そして、 かご揺れの程度が無視できるレベルであれば、 かご 2 0 1はそのまま 走行される。 また、 かご揺れの程度が予め設定されたレベルに達していた場合、 いたずら検出部 2 1 8からエレベータ制御部 2 1 6にいたずら検出信号が入力さ れ、 かご 2 0 1が最寄り階へ移動されて停止される。 このとき、 かご 2 0 1内に 警報やアナウンスを発することも可能である。 If the degree of car shake is negligible, the car 201 is driven as it is. If the degree of car shake has reached a preset level, a tampering detection signal is input from the tampering detection section 218 to the elevator control section 216. The car 201 is moved to the nearest floor and stopped. At this time, it is also possible to issue an alarm or announcement in the car 201.
また、 いたずら検出信号が入力された場合、 かご 2 0 1内に警報やアナウンス を発し、 それでもかご揺れが続く場合にのみ、 かご 2 0 1を最寄り階に停止させ てもよい。 即ち、 いたずら検出信号が出力された場合の制御は、 種々の変更が可 能である。  Further, when the mischief detection signal is input, an alarm or an announcement is issued in the car 201, and the car 201 may be stopped at the nearest floor only when the car continues to shake. That is, the control when the mischief detection signal is output can be variously changed.
このようなエレベータ装置では、 かご 2 0 1で発生した振動は、 かご 2 0 1の 位置に応じた長さ分の主ロープ 2 0 8を介してかご振動検出器 2 1 7によって測 定される。 また、 かご 2 0 1の振動は、 かご 2 0 1の位置に応じた長さ分の調速 機ロープ 2 1 3を介して調速機 2 1 1に伝達される。 従って、 かご振動検出器 2 1 7で検出される振動は、 調速機 2 1 1に設けられた速度センサ 2 1 5に影響す る振動とほぼ同等となる。  In such an elevator system, the vibration generated in the car 201 is measured by the car vibration detector 217 through the main rope 208 corresponding to the position of the car 201 for a length. . In addition, the vibration of the car 201 is transmitted to the governor 211 via the governor rope 21 for a length corresponding to the position of the car 201. Therefore, the vibration detected by the car vibration detector 2 17 is substantially equal to the vibration affecting the speed sensor 2 15 provided in the governor 2 11.
このように、 主ロープ 2 0 8のかご側端部 2 0 8 aの振動をかご振動検出器 2 1 7により検出し、 その検出信号に基づいて検出部 2 1 8でかご揺れの程度を判 断することにより、 いたずらによるかご揺れによって誤って過速度検出されるの をより確実に防止することができる。 また、 いたずらによるかご揺れを誤検出す るのを防止することができる。  In this manner, the vibration of the car-side end 208a of the main rope 208 is detected by the car vibration detector 217, and the degree of car sway is determined by the detector 218 based on the detection signal. This makes it possible to more reliably prevent an overspeed from being erroneously detected due to a car shake caused by mischief. In addition, it is possible to prevent erroneous detection of car shaking due to mischief.
なお、 実施の形態 1 7では、 速度センサ 2 1 5からの信号により過速度を検出 してかご 2 0 1を制動するエレベータ装置を示したが、 従来の機械式の調速機と 機械式の非常止め装置との組み合わせを用レ、るェレベータ装置にもこの発明を適 用でき、 いたずらによるかご揺れを精度良く検出することができる。 実施の形態 1 8 .  In Embodiment 17, the elevator apparatus that detects the overspeed based on the signal from the speed sensor 215 and brakes the car 201 was described. However, a conventional mechanical governor and a mechanical governor were used. The present invention can be applied to a combination of an emergency stop device and an elevator device, and can accurately detect a car shake caused by mischief. Embodiment 18
次に、 図 3 4はこの発明の実施の形態 1 8によるエレベータ装置の要部を示す 正面図である。 この例では、 かご 2 0 1の積载重量を検出するための秤装置 2 2 5に、 いたずらによるかご摇れ検出用のかご振動検出器が設けられている。 秤装置 2 2 5は、 昇降路の上部に回転可能に支持されている検出プーリ 2 2 6 と、 検出プーリ 2 2 6に卷き掛けられた検出ワイヤ 2 2 7と、 検出プーリ 2 2 6 の回転角度を検出するための信号を発生する角度センサ 2 2 8とを有している。 角度センサ 2 2 8は、 かご揺れを検出するための信号を発生するかご振動検出器 を兼ねている。 Next, FIG. 34 is a front view showing a main part of an elevator apparatus according to Embodiment 18 of the present invention. In this example, a weighing device 225 for detecting the accumulated weight of the car 201 is provided with a car vibration detector for detecting a sway due to mischief. The weighing device 2 25 includes a detection pulley 2 26 rotatably supported above the hoistway, a detection wire 2 27 wound around the detection pulley 2 26, and a detection pulley 2 2 6. An angle sensor 228 for generating a signal for detecting a rotation angle. The angle sensor 228 also serves as a car vibration detector that generates a signal for detecting a car shake.
検出ワイヤ 2 2 7の第 1端部は、 取付部材 2 2 4のうちの 1つの上端部に接続 されている。 検出ワイヤ 2 2 7の第 2端部は、 ばね 2 2 9を介してロープ端支持 部 2 1 9 aに接続されている。 ばね 2 2 5は、 検出ワイヤ 2 2 7に張力を付与す る。 角度センサ 2 2 8は、 検出プーリ 2 2 6に搭載されている。 他の構成は、 実 施の形態 1 7と同様である。  A first end of the detection wire 227 is connected to an upper end of one of the mounting members 224. The second end of the detection wire 227 is connected to the rope end support portion 219a via a spring 229. The spring 225 applies a tension to the detection wire 227. The angle sensor 228 is mounted on the detection pulley 226. Other configurations are the same as in Embodiment 17.
次に、 動作について説明する。 ばね 2 2 3は、 かご 2 0 1内の積載重量に応じ て伸縮される。 取付部材 2 2 4は、 ばね 2 2 3の伸縮に応じて上下方向に変位さ れる。 取付部材 2 2 4には検出ワイヤ 2 2 7の第 1端部が接続されているため、 取付部材 2 2 4が変位されると、 その変位量に応じた角度だけ検出プーリ 2 2 6 が回転される。 つまり、 検出プーリ 2 2 6の回転角度は、 かご 2 0 1内の積載重 量に対応している。 従って、 角度センサ 2 2 8からの出力信号を処理することに より、 かご 2 0 1内の積載重量が測定可能となる。  Next, the operation will be described. The springs 222 expand and contract according to the load weight in the car 201. The attachment member 224 is vertically displaced in accordance with the expansion and contraction of the spring 223. Since the first end of the detection wire 222 is connected to the mounting member 222, when the mounting member 222 is displaced, the detection pulley 222 rotates by an angle corresponding to the amount of displacement. Is done. That is, the rotation angle of the detection pulleys 226 corresponds to the load weight in the car 201. Therefore, by processing the output signal from the angle sensor 228, the loaded weight in the car 201 can be measured.
本来、 かご 2 0 1の重量変化は静的な変化であるため、 角度センサ 2 2 8から の出力信号の処理回路としてはサンプリング周期の長いものが用いられている。 これに対して、 いたずらによるかご揺れの周波数は 1〜5 H z程度であり、 この ような揺れを検出するためには、 サンプリング周期の短い処理回路が必要となる。 そこで、 実施の形態 1 8では、 積載重量測定用の処理回路とは別に、 かご揺れ検 出用の処理回路が設けられている。  Originally, the weight change of the car 201 is a static change, and therefore, a circuit with a long sampling cycle is used as a processing circuit for the output signal from the angle sensor 228. On the other hand, the frequency of car shake caused by mischief is about 1 to 5 Hz, and a processing circuit with a short sampling cycle is required to detect such shake. Therefore, in the eighteenth embodiment, a processing circuit for detecting a car swing is provided separately from the processing circuit for measuring the loaded weight.
このようなかご揺れ検出用の処理回路での検出結果に基づいて、 いたずら検出 部 2 1 8によりかご揺れがいたずらによるものであるかどうかが判断される。 従って、 いたずらによるかご揺れによつて誤って過速度検出されるのをより確実 に防止することができるとともに、 いたずらによるかご揺れを誤検出するのを防 止することができる。  Based on the detection result of the car shake detection processing circuit, the mischief detecting section 218 determines whether the car shake is caused by mischief. Therefore, it is possible to more reliably prevent an overspeed from being erroneously detected due to a car shake caused by mischief, and prevent a car shake caused by mischief from being erroneously detected.
また、 既存の角度センサ 2 2 8をかご揺れ検出用の振動検出器として利用する ことができるので、 コストの増加を抑えることができる。 実施の形態 1 9 . 次に、 図 3 5はこの発明の実施の形態 1 9によるエレベータ装置を示す構成図 である。 図において、 エレベータ制御部は、 駆動装置 2 0 5等の運転を制御する 運転制御部 2 3 1と、 エレベータの異常時に駆動装置 2 0 5や非常止め装置によ りかご 2 0 1を停止させる安全監視部 2 3 2とを有している。 In addition, since the existing angle sensor 228 can be used as a vibration detector for detecting a car shake, an increase in cost can be suppressed. Embodiment 19 Next, FIG. 35 is a configuration diagram showing an elevator apparatus according to Embodiment 19 of the present invention. In the figure, the elevator control unit controls the operation of the driving device 205 and the like, and the driving device 205 and the emergency stop device stop the car 201 when the elevator is abnormal. It has a safety monitoring section 2 32.
いたずら検出部 2 1 8からのいたずら検出信号は、 運転制御部 2 3 1とは独立 した安全監視部 2 3 2に入力される。 安全監視部 2 3 2にいたずら検出信号が入 力されると、 安全監視部 2 3 2の安全スィッチ 2 3 2 aがオフにされ、 駆動装置 2 0 5への通電が遮断される。 これにより、 駆動装置 2 0 5のモータの駆動が停 止されるとともに、 ブレーキ装置により駆動シーブ 2 0 6が制動され、 かご 2 0 1が非常停止される。 他の構成は、 実施の形態 1 7と同様である。  The tampering detection signal from the tampering detection section 2 18 is input to a safety monitoring section 2 32 independent of the operation control section 2 31. When the tampering detection signal is input to the safety monitoring section 232, the safety switch 232a of the safety monitoring section 232 is turned off, and the power supply to the driving device 205 is cut off. As a result, the driving of the motor of the driving device 205 is stopped, the driving sheave 206 is braked by the brake device, and the car 201 is emergency stopped. Other configurations are the same as those of the seventeenth embodiment.
このような構成によれば、 運転制御部 2 3 1が暴走した場合であっても、 いた ずらによるかご揺れによって誤つて過速度検出されるのをより確実に防止するこ とができるとともに、 いたずらによるかご揺れを誤検出するのを防止することが できる。  According to such a configuration, even when the operation control unit 231 runs out of control, it is possible to more reliably prevent an overspeed from being erroneously detected due to a sway of the car due to mischief. This can prevent erroneous detection of car shaking due to
なお、 実施の形態 1 9では、 いたずら検出部 2 1 8を安全監視部 2 3 2の一部 とすることもできる。 実施の形態 2 0 .  In Embodiment 19, the mischief detection unit 2 18 can be a part of the safety monitoring unit 2 32. Embodiment 20.
次に、 図 3 6はこの発明の実施の形態 2 0によるエレベータ装置を示す構成図 である。 図において、 いたずら検出部 2 1 8からのいたずら検出信号は、 検出さ れたかご揺れのレベルに応じて運転制御部 2 3 1及び安全監視部 2 3 2のいずれ か一方に選択的に入力される。  Next, FIG. 36 is a configuration diagram showing an elevator apparatus according to Embodiment 20 of the present invention. In the figure, the tampering detection signal from the tampering detection unit 218 is selectively input to one of the operation control unit 231 and the safety monitoring unit 232 according to the detected level of the car swing. You.
例えば、 かご揺れのレベルが予め設定されたレベルよりも低い場合には、 運転 制御部 2 3 1にいたずら検出信号が入力され、 かご 2 0 1が最寄り階に移動され 停止される。 また、 かご揺れのレベルが予め設定されたレベル以上の場合には、 安全監視部 2 3 2にいたずら検出信号が入力され、 かご 2 0 1が非常停止される。 このように、 かご揺れのレベルに応じて、 かご揺れ検出後に異なる制御を実施 することも可能である。 実施の形態 2 1 . For example, if the car swing level is lower than a preset level, a mischief detection signal is input to the operation control section 231, and the car 201 is moved to the nearest floor and stopped. If the level of the car sway is equal to or higher than the preset level, a tamper detection signal is input to the safety monitoring section 232, and the car 201 is emergency stopped. As described above, it is also possible to execute different control after the detection of the car sway according to the level of the car sway. Embodiment 21.

That is, the car 201 and the counterweight 203 are suspended in a 1: 1 roving manner by the main rope 208.
かご 2 0 1には、 かご 2 0 1の振動を検出するための信号を発生するかご振動 検出器 2 3 4が搭載されている。 調速機 2 1 1には、 調速機 2 1 1の振動を検出 するため'の信号を発生する調速機振動検出器 2 3 5が搭載されている。 かご振動 検出器 2 3 4及び調速機振動検出器 2 3 5からの信号は、 いたずら検出部 2 1 8 に入力される。 他の構成は、 実施の形態 1 7と同様である。  The car 201 is equipped with a car vibration detector 234 that generates a signal for detecting the vibration of the car 201. The governor 2 11 1 is equipped with a governor vibration detector 2 35 that generates a signal for detecting the vibration of the governor 2 11. Signals from the car vibration detector 234 and the governor vibration detector 235 are input to the tamper detector 218. Other configurations are the same as those of the seventeenth embodiment.
図 3 8は図 3 7のいたずら検出部 2 1 8の動作を示すフローチヤ一トである。 エレベータの通常運転実施中、 いたずら検出部 2 1 8では、 調速機振動検出器 2 3 5からの信号に基づいて、 調速機 2 1 1が振動したかどうかが監視される (ス テツプ S 1 ) 。 調速機 2 1 1の振動が検出されなければ、 そのまま通常運転が継 売さ; る。  FIG. 38 is a flowchart showing the operation of the mischief detection unit 218 of FIG. During normal operation of the elevator, the tamper detector 2 18 monitors whether or not the governor 211 has vibrated based on the signal from the governor vibration detector 235 (Step S). 1). If the vibration of the governor 2 1 1 is not detected, the normal operation is continued as it is;
調速機 2 1 1の振動が検出されると、 その振動の程度が第 1基準値以上かどう かが確認される (ステップ S 2 ) 。 第 1基準値は、 誤って過速度が検出される振 動のレベルよりも低く設定されている。  When the vibration of the governor 211 is detected, it is checked whether the degree of the vibration is equal to or more than the first reference value (step S2). The first reference value is set lower than the vibration level at which overspeed is erroneously detected.
調速機 2 1 1の振動が第 1基準値以上であれば、 ェレベータ制御部 2 1 6に対 していたずら検出信号が出力される (ステップ S 3 ) 。  If the vibration of the governor 2 11 is equal to or greater than the first reference value, a tampering detection signal is output to the elevator control unit 2 16 (step S 3).
調速機 2 1 1の振動が第 1基準値未満であった場合、 今度は、 調速機 2 1 1の 振動の程度が第 2基準値以上かどうかが確認される (ステップ S 4 ) 。 第 2基準 値は、 第 1基準値よりも低く設定されているのは勿論である。 振動の程度が第 2 基準値未満であれば、 そのまま通常運転が継続される。  If the vibration of the governor 211 is less than the first reference value, then it is checked whether the degree of vibration of the governor 211 is greater than or equal to the second reference value (step S4). The second reference value is, of course, set lower than the first reference value. If the degree of vibration is less than the second reference value, normal operation is continued.
調速機 2 1 1の振動が第 2基準値以上、 第 1基準値未満であれば、 かご振動検 出器 2 3 4からの信号に基づいて、 かご 2 0 1が振動したかどうかが確認される (ステップ S 5 ) 。 かご 2 0 1の捩動が検出されなければ、 そのまま通常運転が 継続される。 If the vibration of the governor 2 1 1 is greater than or equal to the second reference value and less than the first reference value, Based on the signal from the output device 234, it is confirmed whether the car 201 has vibrated (step S5). If the torsion of the car 201 is not detected, the normal operation is continued.
かご 2 0 1の振動が検出された場合、 その振動は乗客のいたずらによるもので ある可能性が高いと判断し、 いたずら検出信号が出力される (ステップ S 3 ) 。 いたずら検出信号が出力された後のエレベータの制御方法としては、 例えば実 施の形態 1 7、 1 9、 2 0のいずれかの方法を実施することができる。 具体的に は、 例えばいたずら検出信号が出力されたら、 かご 2 0 1を最寄り階に停止させ る制御方法を適用することができる。 また、 調速機 2 1 1の振動が第 1基準値以 上の場合には、 かご 2 0 1を非常停止させ、 調速機 2 1 1の振動が第 1基準値未 満、 第 2基準値以上であり、 かっかご 2 0 1の振動が検出された場合には、 かご 2 0 1を最寄り階に停止させる制御方法を適用することができる。  When the vibration of the car 201 is detected, it is determined that the vibration is likely to be caused by the mischief of the passenger, and a mischief detection signal is output (step S3). As a method of controlling the elevator after the mischief detection signal is output, for example, any one of the embodiments 17, 19, and 20 can be implemented. Specifically, for example, when a mischief detection signal is output, a control method of stopping the car 201 at the nearest floor can be applied. If the vibration of the governor 211 is equal to or greater than the first reference value, the car 201 is emergency stopped, and the vibration of the governor 211 is less than the first reference value. If the value is equal to or more than the value and the vibration of the basket 201 is detected, a control method for stopping the basket 201 to the nearest floor can be applied.
このようなエレベータ装置では、 調速機 2 1 1の振動を調速機振動検出器 2 3 5で検出するとともに、 かご 2 0 1の振動をかご振動検出器 2 3 4で検出するの で、 調速機 2 1 1の振動をより早期に検出できるとともに、 調速機 2 1 1の振動 がかご 2 0 1を揺らしたことによるものかどうかをより正確に判断することがで きる。 従って、 いたずらによるかご摇れによって誤って過速度検出されるのをよ り確実に防止することができるとともに、 いたずらによるかご揺れを誤検出する のを防止することができる。  In such an elevator device, the vibration of the governor 211 is detected by the governor vibration detector 235, and the vibration of the car 201 is detected by the car vibration detector 234. The vibration of the governor 211 can be detected earlier, and it can be more accurately determined whether or not the vibration of the governor 211 is caused by the swing of the car 201. Therefore, it is possible to more reliably prevent an overspeed from being erroneously detected due to a car due to mischief, and to prevent a car shake due to mischief from being erroneously detected.
なお、 かご振動検出器は、 かごの揺れを検出できればどこに配置してもよレ、。 例えば、 実施の形態 1 7〜2 0に示したように、 2 : 1ロービング方式のエレ ベータ装置であれば、 主ロープのかご側端部の振動を検出することにより、 かご の振動を間接的に検出するようにしてもよい。  The car vibration detector can be placed anywhere as long as it can detect the swing of the car. For example, as shown in Embodiments 17 to 20, in the case of a 2: 1 roving type elevator apparatus, the vibration of the car is indirectly detected by detecting the vibration at the car side end of the main rope. May be detected.
また、 かご振動検出器をかごに搭載する場合、 かご振動検出器は、 かご枠及び かご室のいずれに設けてもよいが、 かご室に直接設けることにより、 かご室内の 乗客のいたずらによるかご摇れをより確実に検出することができる。 また、 かご 室にかご振動検出器を設ける場合、 かご枠に固定されたかご室下部よりも、 かご 室上部にかご振動検出器を設置することにより、 かご揺れの検出感度をより高く することができる。 実施の形態 2 2 . When the car vibration detector is mounted on the car, the car vibration detector may be provided in either the car frame or the car room. However, by providing the car vibration detector directly in the car room, the car vibration detector can be used for mischief of passengers in the car room. Can be detected more reliably. In addition, when a car vibration detector is installed in a car room, it is possible to increase the detection sensitivity of the car shake by installing the car vibration detector at the top of the car room rather than at the bottom of the car room fixed to the car frame. it can. Embodiment 22.
次に、 図 3 9はこの発明の実施の形態 2 2によるエレベータ装置を示す構成図 である。 この例では、 調速機ロープ 2 1 3が制振装置 2 3 6を介してかご 2 0 1 に接続されている。 図 4 0は図 3 9の制振装置 2 3 6を拡大して示す側面図であ る。  Next, FIG. 39 is a configuration diagram showing an elevator apparatus according to Embodiment 22 of the present invention. In this example, the governor rope 2 13 is connected to the car 201 via the damping device 2 36. FIG. 40 is an enlarged side view of the vibration damping device 236 of FIG.
また、 かご振動検出器 2 1 7からの信号は、 D ZAコンバータ 2 3 7及びフィ ルタ 2 3 8を介していたずら検出部 2 1 8に入力される。 フィルタ 2 3 8は、 か ご 2 0 1から調速機 2 1 1への振動の伝達特性と、 かご 2 0 1からかご振動検出 器 2 1 7への振動の伝達特性の違いによるかご振動検出器 2 1 7での検出誤差を 補正する。  The signal from the car vibration detector 217 is input to the tampering detection unit 218 via the DZA converter 237 and the filter 238. The filter 238 detects car vibration due to the difference between the vibration transmission characteristics from the car 201 to the governor 211 and the vibration transmission characteristics from the car 201 to the car vibration detector 217. Correct the detection error of the detector 2 17.
即ち、 フィルタ 2 3 8を通すことにより、 かご振動検出器 2 1 7で検出される 振動は、 調速機 2 1 1の振動に近づけられる。 フィルタ 2 3 8では、 かご室の重 量 M l、 かご室を支持するかご枠の重量 M 2、 かご室とかご枠との間に設けられ た防振ゴムの剛性 K 1、 主ロープ 2 0 8の剛性 K r、 制振装置 2 3 6のばね剛性 K c、 調速機ロープ 2 1 3の剛性 K g等のパラメータを用いて、 検出信号が補正 される。  That is, the vibration detected by the car vibration detector 217 by passing through the filter 238 is approximated to the vibration of the governor 211. In the filter 238, the weight of the cab is Ml, the weight of the car frame supporting the cab M2, the rigidity of the vibration isolating rubber provided between the cab and the car frame K1, and the main rope 20 The detection signal is corrected using parameters such as the stiffness Kr of 8, the spring stiffness Kc of the vibration damping device 236, and the stiffness Kg of the governor rope 2 13.
図 4 1は図 3 9のフィルタ 2 3 8による信号補正の一例を示す説明図である。 例えば、 (a ) に示すような検出信号に対して、 伝達特性を考慮した補正をかけ ることにより、 (b ) に示すような信号を得ることができる。  FIG. 41 is an explanatory diagram showing an example of signal correction by the filter 238 in FIG. For example, a signal shown in (b) can be obtained by performing a correction in consideration of the transfer characteristic on the detection signal shown in (a).
これにより、 いたずらによるかご揺れによって誤って過速度検出されるのをよ り確実に防止することができるとともに、 いたずらによるかご揺れを誤検出する のを防止することができる。  As a result, it is possible to more reliably prevent an overspeed from being erroneously detected due to a car shake caused by mischief, and prevent a car shake caused by mischief from being erroneously detected.
なお、 フィルタ 2 3 8による補正は、 制振装置 2 3 6を用いないエレベータ装 置にも適用できる。  The correction by the filter 238 can also be applied to an elevator device that does not use the vibration damping device 236.
また、 実施の形態 2 1のいたずら判定のアルゴリズムにおいても、 調速機振動 検出器 2 3 5やかご振動検出器 2 3 4からの信号にフィルタ 2 3 8による補正を かけることにより、 判定精度を向上させることができる。  Also, in the mischief determination algorithm of Embodiment 21, the determination accuracy is improved by applying a correction by a filter 238 to a signal from the governor vibration detector 235 and the cage vibration detector 234. Can be improved.
さらに、 1つの検出信号に対して複数のフィルタによる補正をかけることも可 能である。 図 4 2は 1つの振動検出器からの検出信号に対して 2種類の補正をか ける例を示す説明図である。 図に示すように、 検出位置から調速機までの伝達特 性 Aに基づいた補正をかけることにより、 補正後の信号を調速機の揺れ判定に用 いることができる。 また、 検出位置からかごまでの伝達特性 Bに基づいた補正を かけることにより、 補正後の信号をかごの揺れ判定に用いることができる。 従つ て、 1つの振動検出器を用いて、 かごの揺れと調速機の揺れとを検出でき、 実施 の形態 2 1に示したような制御方法を実施することができる。 In addition, it is possible to apply multiple filters to one detection signal. Noh. FIG. 42 is an explanatory diagram showing an example in which two types of correction are applied to a detection signal from one vibration detector. As shown in the figure, by applying a correction based on the transmission characteristic A from the detection position to the governor, the signal after the correction can be used for judging the fluctuation of the governor. Further, by applying a correction based on the transfer characteristic B from the detection position to the car, the corrected signal can be used for determining the swing of the car. Therefore, the swing of the car and the swing of the governor can be detected by using one vibration detector, and the control method as described in Embodiment 21 can be implemented.
さらにまた、 伝達特性についてのフィルタを様々な機種のェレベータに適用さ せるため、 エレベータの設置直後に伝達特性を同定するための運転動作を実施す るようにしてもよい。  Furthermore, in order to apply the filter for the transfer characteristics to various types of elevators, a driving operation for identifying the transfer characteristics may be performed immediately after the elevator is installed.
また、 フィルタに用いるパラメータは、 上記の例に限定されるものではなく、 例えば昇條行程や容量などを含んでもよい。  Further, the parameters used for the filter are not limited to the above example, and may include, for example, a rising stroke and a capacity.
