Description

本発明は、エレベーターが地震などで運転休止した場合の、復旧運転方法および装置に関する。   The present invention relates to a recovery operation method and apparatus when an elevator stops operation due to an earthquake or the like.

一般に、エレベーターが地震時に運転休止した場合、エレベーターにどの程度の被害があったのか、異常の有無を保守・点検の専門技術者が確認するまではエレベーターを停止させる状態となる。昨今、地震が多発しており、都市部等ビルが密集する地域では、地震感知器が動作し、多くのエレベーターが運転休止状態となってしまう。このとき、保守契約をしている保守・点検の専門技術者が巡回点検する訳であるが、台数が多いために、対応に時間がかかり、復旧するまで、ビルやマンション内のエレベーター利用者は、エレベーターを利用できない状態を強いられる。   In general, when an elevator is shut down during an earthquake, the elevator is stopped until a maintenance / inspection engineer confirms how much damage the elevator has had and whether there is an abnormality. In recent years, earthquakes have occurred frequently, and in areas where buildings are densely populated, such as urban areas, earthquake detectors operate and many elevators are put into operation suspension. At this time, maintenance / inspection technicians who have a maintenance contract carry out patrol inspections, but due to the large number of units, it takes time to respond, and elevator users in buildings and apartments are not , Forced to use the elevator.

例えば、特許文献1に開示されているように、機器の損傷が殆ど発生しないような地震レベルでは、エレベーターの異常の有無を確認する低速診断運転を行い、異常がないことを確認できた場合はエレベーターを自動復旧させる。一方、機器の損傷が発生し易い地震レベルでは、自動復旧運転を避けて、エレベーター保守会社に地震復旧運転が不可能である旨の通報を送信するものが知られている。   For example, as disclosed in Patent Document 1, at an earthquake level where almost no equipment damage occurs, a low-speed diagnostic operation is performed to check whether there is an abnormality in the elevator, and if there is no abnormality, Automatically restore the elevator. On the other hand, it is known that at an earthquake level where equipment damage is likely to occur, automatic restoration operation is avoided and a notification that earthquake restoration operation is impossible is sent to an elevator maintenance company.

また、例えば、特許文献2には、エレベーターを低速運転させているときに、乗りかごに取り付けた各異常検出センサーの出力をチェックし、異常が検出されなければ自動復旧させることが提案されている。   For example, Patent Document 2 proposes that when the elevator is operated at a low speed, the output of each abnormality detection sensor attached to the car is checked, and if an abnormality is not detected, automatic recovery is proposed. .

特開2006−151678号公報JP 2006-151678 A 特開2004−355296号公報JP 2004-355296 A

特許文献1には、地震のレベルを複数段階に分けて検知するほか、制御ケーブルの引っ掛り検出装置を備え、これが引っ掛りを検出しないときに自動復旧させることが記載されている。この制御ケーブルの引っ掛り検出装置は、引っ掛りによる制御ケーブルの変位を検知するようになっている。   Patent Document 1 describes that the level of an earthquake is detected in a plurality of stages and that a control cable catch detection device is provided and is automatically restored when no catch is detected. This control cable catch detection device detects displacement of the control cable due to catch.

しかしながら、かごの位置に応じて、かごから垂れ下がる制御ケーブルの長さが変動し、その重量も大きく変動する。この変動による変位範囲は不感帯としなければならず、事故の現象次第では引っ掛りを検出できないことも考えられる。大きな変位がなければ検知できないし、また、反対方向への変位も検出できない。   However, depending on the position of the car, the length of the control cable hanging from the car fluctuates and its weight fluctuates greatly. The displacement range due to this variation must be a dead zone, and it may be impossible to detect a catch depending on the accident phenomenon. Without large displacement, it cannot be detected, and displacement in the opposite direction cannot be detected.

特許文献1では、主ロープの引っ掛り検出についての開示は無く、異常検知が不十分である。高層ビルになるに従い、地震による主ロープの揺れも大きくなり、昇降路内機器に引っ掛る可能性も大きくなる。このため、主ロープの昇降路内機器への引っ掛りを考慮することは非常に重要である。また、特に、高層エレベーターでは、釣合い重り側とかご側とのぶら下がり重量の不均衡を解消するための釣合いケーブルを適用する場合が多く、この釣合いケーブルの昇降路内機器への引っ掛りを検知できずに破断事故が発生する可能性がある。   In Patent Document 1, there is no disclosure about hook detection of the main rope, and abnormality detection is insufficient. As the building becomes taller, the main rope will sway due to the earthquake, and the possibility of getting caught by equipment in the hoistway will increase. For this reason, it is very important to consider the main rope being caught on the equipment in the hoistway. In particular, in high-rise elevators, there are many cases where a balancing cable is used to eliminate the imbalance in the hanging weight between the counterweight side and the car side. A breakage accident may occur.

一方、特許文献2に開示されたものも、同様に主ロープの引っ掛りや、釣合いケーブルの引っ掛りを確実に検出できる構成となっていない。このため、主ロープ及び釣合いケーブルの昇降路内機器への引っ掛りによって、復旧運転時に重大な損傷を与えてしまう可能性がある。   On the other hand, the one disclosed in Patent Document 2 is not configured to reliably detect the hook of the main rope and the hook of the balance cable. For this reason, there is a possibility that the main rope and the balance cable may be seriously damaged during the recovery operation due to the catching on the equipment in the hoistway.

本発明の目的は、地震などでエレベーターが休止状態となった場合に、昇降路内の長尺物の引っ掛りに起因する異常状態での復旧運転を抑制し、安全な場合にのみエレベーターを自動復旧できる復旧運転方法および装置を提供することである。   The purpose of the present invention is to suppress recovery operation in an abnormal state caused by a long object in the hoistway when the elevator is stopped due to an earthquake or the like, and the elevator is automatically operated only when it is safe. It is to provide a restoration operation method and apparatus that can be restored.

本発明は、その一面において、主ロープによりかごと釣合い重りが連結され、巻上機により駆動されるエレベーターにおいて、かごの上部に配置された第1の加速度センサー、かごの下部に配置された第2の加速度センサー、前記主ロープの両端部をそれぞれ支持する部材の主ロープ端部近傍に配置された第3および第4の加速度センサー、並びにガバナの近傍に配置された第5の加速度センサーを備え、低速診断運転を行って、任意の前記加速度センサーの出力が所定の異常値を示したことに応じて、エレベーターの復旧運転を禁止し、全ての前記加速度センサーの出力が異常値を示さず、かつ地震感知器が動作しないとき、エレベーターの復旧を許可する復旧許可手段を備えたことを特徴とする。   In one aspect of the present invention, in an elevator in which a car and a counterweight are connected by a main rope and driven by a hoisting machine, a first acceleration sensor disposed at the upper part of the car, and a first acceleration sensor disposed at the lower part of the car. 2 acceleration sensors, third and fourth acceleration sensors disposed in the vicinity of the main rope ends of the members that respectively support both ends of the main rope, and a fifth acceleration sensor disposed in the vicinity of the governor. The low-speed diagnostic operation is performed, and in response to the output of any of the acceleration sensors showing a predetermined abnormal value, the elevator recovery operation is prohibited, and the outputs of all the acceleration sensors do not show the abnormal value, And when the seismic sensor does not operate, it is provided with a restoration permission means for permitting restoration of the elevator.

本発明の望ましい実施態様においては、前記低速診断運転を行って、全ての前記加速度センサーの出力が異常値を示さず、かつ前記地震感知器が動作したとき、この地震感知器をリセットし、再度低速診断運転を行う。   In a preferred embodiment of the present invention, when the low-speed diagnostic operation is performed and all the acceleration sensor outputs do not indicate an abnormal value and the seismic sensor is activated, the seismic sensor is reset, and again Perform low-speed diagnostic operation.

本発明の他の望ましい実施態様においては、前記低速診断運転を行って、任意の前記加速度センサーの出力が所定の異常値を示したことに応じて、エレベーターの復旧運転を禁止するとともに、所定の異常値を示した前記加速度センサーの出力に基づく異常の分析手段を備えている。   In another preferred embodiment of the present invention, the low-speed diagnosis operation is performed, and when the output of any of the acceleration sensors indicates a predetermined abnormal value, the restoration operation of the elevator is prohibited, An abnormality analyzing means based on the output of the acceleration sensor indicating an abnormal value is provided.

また、本発明の望ましい実施態様においては、前記低速診断運転は、一往復である。   In a preferred embodiment of the present invention, the low-speed diagnosis operation is one round trip.

さらに、本発明の望ましい実施態様においては、前記低速診断運転は、かご内に乗客が居ないこと並びにエレベーターの安全装置が動作していないことを条件として起動する。   Further, in a preferred embodiment of the present invention, the low-speed diagnosis operation is started on condition that there are no passengers in the car and that the elevator safety device is not operating.

本発明の望ましい実施態様によれば、休止状態となったエレベーターの昇降路内のどこに長尺物の引っ掛り等の異常が発生しても確実に異常を検知でき、安全な場合にのみ自動復旧運転できるとともに、各機器の損傷を最小限に抑制することが出来る。   According to a preferred embodiment of the present invention, an abnormality can be reliably detected no matter where an abnormality such as a long object is caught in a hoistway of an elevator that has been stopped, and is automatically restored only when it is safe. In addition to being able to operate, damage to each device can be minimized.

また、本発明の望ましい実施形態によれば、各箇所に設置した加速度センサーの出力を分析することにより、エレベーターの異常箇所を特定することも可能である。   Further, according to a preferred embodiment of the present invention, it is possible to identify an abnormal location of the elevator by analyzing the output of the acceleration sensor installed at each location.

また、地震時に運転休止した場合には、各加速度センサーの出力を低速診断運転時に収集して、エレベーター装置の復旧運転の可否を自己判断するため、地震等の災害後に多くのエレベーターが速やかに自動復旧できる。また、この加速度センサーによる異常検知は、保守・点検時の点検作業としても効果がある。   In addition, when the operation is stopped during an earthquake, the output of each acceleration sensor is collected during the low-speed diagnostic operation, and self-determination of whether or not the elevator device can be restored, so that many elevators can quickly and automatically operate after a disaster such as an earthquake. It can be recovered. Further, the abnormality detection by the acceleration sensor is also effective as an inspection work during maintenance / inspection.

本発明のその他の目的と特徴は、以下に述べる実施形態の中で明らかにする。   Other objects and features of the present invention will be clarified in the embodiments described below.

以下に、本発明の一実施例によるエレベーターの復旧運転方法および装置について図面を用いて説明する。   Hereinafter, an elevator restoration operation method and apparatus according to an embodiment of the present invention will be described with reference to the drawings.

図1は、本発明の一実施例によるエレベーターの復旧運転装置の昇降路内概略構造を示すイメージ図であり、地震やその他外力による異常振動により運転休止した場合の復旧運転を可能にするための異常検出手段の配置構成を示す。   FIG. 1 is an image diagram showing a schematic structure in a hoistway of an elevator restoration operation apparatus according to an embodiment of the present invention, and an abnormality for enabling restoration operation when operation is stopped due to an abnormal vibration caused by an earthquake or other external force. The arrangement structure of a detection means is shown.

図1において、エレベーターのかご1は主ロープ2により釣合い重り3と連結され、主ロープ2の方向を変える滑車4、5を介して、巻上機6に掛けられ、主ロープ2の両端はガイドレール(図示せず)に連結されたロープエンド7a、7bにより固定されている。また、かご1は制御ケーブル8により、昇降路等に設置された制御回路9に接続されている。かご1と釣合い重り3との間で主ロープ2の重量の不均衡を解消するために、かご1と釣合い重り3は、釣合いケーブル10で接続されている。   In FIG. 1, an elevator car 1 is connected to a counterweight 3 by a main rope 2 and is hung on a hoisting machine 6 via pulleys 4 and 5 that change the direction of the main rope 2, and both ends of the main rope 2 are guides. It is fixed by rope ends 7a and 7b connected to a rail (not shown). The car 1 is connected by a control cable 8 to a control circuit 9 installed in a hoistway or the like. In order to eliminate the imbalance of the weight of the main rope 2 between the car 1 and the counterweight 3, the car 1 and the counterweight 3 are connected by a counter cable 10.

また、かご1は、かご内の乗客の有無を検出するパッシブセンサー、かご秤装置、かご内監視カメラ(何れも図示せず)等を備えており、かご1内に乗客がいないことを検知することができる。主ロープのロープエンド7aと7b、及びかご1には、主ロープの昇降路内の機器への引っ掛りを検出するために、主ロープ引っ掛り検出用加速度センサー11a、11b、11cを設ける。すなわち、主ロープ2は、昇降路頂部の梁15にそのロープエンド7aと7bが支持されており、これらロープエンド7a,7bの支持部近傍の梁15上に、加速度センサー11a,11bをそれぞれ載置している。また、主ロープ2は、かご1を搭載するかご枠を吊っているので、その上枠16上に加速度センサー11cを載置している。主ロープ2が、それぞれの位置で昇降路内で引っ掛ると、通常とは明らかに異なる振動を加速度センサー11a,11bまたは11cが感知するので、これを基準範囲内の周波数と比較することで、主ロープ2の引っ掛りを確実に検知できる。   In addition, the car 1 includes a passive sensor that detects the presence or absence of passengers in the car, a car scale device, an in-car monitoring camera (none of which are shown), and detects that there are no passengers in the car 1. be able to. The rope ends 7a and 7b of the main rope and the car 1 are provided with main rope catch detection acceleration sensors 11a, 11b and 11c in order to detect the catch of the main rope on the equipment in the hoistway. That is, the ropes 7a and 7b of the main rope 2 are supported on the beam 15 at the top of the hoistway, and the acceleration sensors 11a and 11b are mounted on the beam 15 in the vicinity of the support part of the rope ends 7a and 7b, respectively. It is location. Further, since the main rope 2 suspends the car frame on which the car 1 is mounted, the acceleration sensor 11 c is placed on the upper frame 16. When the main rope 2 is caught in the hoistway at each position, the acceleration sensor 11a, 11b or 11c senses a vibration that is clearly different from the normal one. By comparing this with the frequency within the reference range, The main rope 2 can be reliably caught.

次に、ガバナロープ12の昇降路内機器への引っ掛りを検出するために、ガバナ13にガバナロープ引っ掛り検出用加速度センサー11dを設ける。すなわち、ガバナ13を載置した梁17上に近接させて、加速度センサー11dを載置している。ガバナロープ12が、昇降路内で引っ掛ると、通常とは明らかに異なる振動を加速度センサー11dが感知するので、これを基準範囲内の周波数と比較することで、ガバナロープ12の引っ掛りを確実に検知できる。   Next, in order to detect the catch of the governor rope 12 on the equipment in the hoistway, the governor 13 is provided with a governor rope catch detection acceleration sensor 11d. That is, the acceleration sensor 11d is placed close to the beam 17 on which the governor 13 is placed. When the governor rope 12 is caught in the hoistway, the acceleration sensor 11d senses vibrations that are clearly different from normal ones. By comparing this with the frequency within the reference range, the catch of the governor rope 12 is reliably detected. it can.

また、制御ケーブル8及び釣合いケーブル10の昇降路内の機器への引っ掛りを検出するために、加速度センサー11eを設ける。これらの制御ケーブル8と釣合いケーブル10のかご側端は、図示するように、かご1の下枠18に支持されているので、この下枠18の振動を検出するように、加速度センサー11eを設けている。やはり、制御ケーブル8または釣合いケーブル10が、昇降路内で引っ掛ると、通常とは明らかに異なる振動を加速度センサー11eが感知するので、これを基準範囲内の周波数と比較することで、制御ケーブル8または釣合いケーブル10の引っ掛りを確実に検知できる。   In addition, an acceleration sensor 11e is provided in order to detect the control cable 8 and the balance cable 10 being caught on the devices in the hoistway. Since the car side ends of the control cable 8 and the balance cable 10 are supported by the lower frame 18 of the car 1 as shown in the figure, an acceleration sensor 11e is provided to detect the vibration of the lower frame 18. ing. Again, when the control cable 8 or the balance cable 10 is caught in the hoistway, the acceleration sensor 11e senses a vibration that is clearly different from the normal one. Therefore, by comparing this with the frequency within the reference range, the control cable 8 or the counter cable 10 can be reliably detected.

なお、初期微動を感知することが可能な地震感知器14が、この実施例では、昇降路壁に取り付けられている。   In this embodiment, a seismic sensor 14 capable of sensing the initial tremor is attached to the hoistway wall.

図2は、本発明の一実施例によるエレベーターの復旧運転方法の処理フローである。   FIG. 2 is a process flow of an elevator restoration operation method according to an embodiment of the present invention.

地震やその他の外力による異常振動により運転休止状態となったエレベーターの自動復旧のフローを説明する。地震やその他の外力による異常振動によってエレベーターが最寄り階にて運転休止した状態でこの処理がスタートする。まず、ステップ201では、かご1に備えられているパッシブセンサー、かご秤装置、かご内監視カメラの何れかにより、かご内に乗客がいないことを検知する。ステップ202では、安全装置の作動の有無を確認し、安全装置が作動していない場合、ステップ203で、一往復の低速診断運転を行う。   The flow for automatic restoration of elevators that have been suspended due to abnormal vibration due to earthquakes and other external forces will be described. This process starts with the elevator stopped at the nearest floor due to an abnormal vibration caused by an earthquake or other external force. First, in step 201, it is detected that there is no passenger in the car by any of the passive sensor, car balance device, and car monitoring camera provided in the car 1. In step 202, it is confirmed whether or not the safety device is operating. If the safety device is not operating, in step 203, a one-way reciprocating low-speed diagnosis operation is performed.

安全装置が作動している場合は、復旧は不可能ということで、ステップ204に飛んで、運転休止とし、ステップ205にて各加速度センサーの出力データを解析し、異常状態を分析する。その後、この処理を終了し、保守専門の技術員による復旧作業を待つ。   If the safety device is in operation, it is impossible to recover. Therefore, the process jumps to step 204 to stop operation, and in step 205, the output data of each acceleration sensor is analyzed to analyze the abnormal state. Thereafter, this process is terminated, and a recovery work by a maintenance engineer is awaited.

さて、ステップ203の低速診断運転に基づく判定ステップ206で、加速度センサー11a〜11eによる検出周波数が、いずれも所定の範囲内にあるとする。この場合、基準の周波数の範囲にあることから、異常を検知せず、したがって、長尺物の昇降路内機器への引っ掛りは無く、また、かご1や釣合い重り3と昇降路内機器との衝突等は無いものと判定できる。しかも、ステップ207で、地震感知器14が初期微動を感知しない場合、ステップ208にてエレベーターが自己診断により復旧運転を許可し、自動的に復旧運転する。   Now, in the determination step 206 based on the low-speed diagnosis operation in step 203, it is assumed that the detection frequencies by the acceleration sensors 11a to 11e are all within a predetermined range. In this case, since it is in the range of the reference frequency, no abnormality is detected. Therefore, there is no catch of the long object on the equipment in the hoistway, and the car 1, the counterweight 3 and the equipment in the hoistway It can be determined that there is no collision. In addition, if the earthquake detector 14 does not detect the initial fine movement in step 207, the elevator permits the recovery operation by self-diagnosis in step 208 and automatically performs the recovery operation.

低速診断運転中に、加速度センサー11a〜11eの何れも異常を検知しなかったものの、地震感知器14が初期微動を感知した場合には、ステップ209にて地震感知器14をリセットし、再び、ステップ203にて低速診断運転を行う。これにより、判定ステップ206で、検知された地震の初期微動による長尺物の引っ掛りなどを再チェックする。   If none of the acceleration sensors 11a to 11e detected an abnormality during the low-speed diagnosis operation, but the seismic sensor 14 senses initial tremor, the seismic sensor 14 is reset in step 209, and again, In step 203, low speed diagnosis operation is performed. Thereby, in the determination step 206, the long object is caught by the initial tremor of the detected earthquake again.

一方、低速診断運転中に、加速度センサー11a〜11eの何れかが異常を検知した場合は、安全装置が動作した場合と同じく、自動復旧は不可能と判断する。したがって、ステップ205で運転休止し、ステップ206にて各加速度センサーの出力データを解析し、異常状態を分析する。その後、この処理を終了し、保守専門の技術員による復旧作業を待つ。   On the other hand, if any of the acceleration sensors 11a to 11e detects an abnormality during the low-speed diagnosis operation, it is determined that automatic recovery is impossible as in the case where the safety device operates. Therefore, the operation is stopped in step 205, and the output data of each acceleration sensor is analyzed in step 206 to analyze the abnormal state. Thereafter, this process is terminated, and a recovery work by a maintenance engineer is awaited.

尚、本実施例においては、2:1ローピングについて記述したが、1:1ローピングにあっても同様の効果が期待できる。また、本実施例では地震時のみ記述したが、点検運転としても有効である。   In this embodiment, 2: 1 roping is described, but the same effect can be expected even in 1: 1 roping. In this embodiment, only an earthquake is described, but it is also effective as an inspection operation.
