Description

この発明は、エレベータ釣合い錘・調速機ロープ張り車のクリアランス管理測定装置及びその方法に関するものである。   The present invention relates to a clearance management measuring apparatus and method for an elevator counterweight / governor rope tensioned vehicle.

従来、エレベータのカウンタクリアランスの測定を自動化し、エレベータの保守時間を短縮し、さらに作業者がエレベータピットに入る等の煩雑な作業を無くすため、エレベータかごと、釣合い錘と、エレベータかごが最上階にある時に、釣合い錘の位置を検出するカムおよび検出部と、検出部の出力値を、初期設定時の釣合い錘と緩衝器の間のカウンタクリアランスの実測値に基づいて換算演算して、実際のカウンタクリアランスを出力するエレベータ制御コンピュータとを備えるエレベータのカウンタクリアランス測定装置が知られている（例えば、特許文献１参照）。   Conventionally, in order to automate the measurement of elevator counter clearance, shorten the elevator maintenance time, and eliminate complicated work such as entering the elevator pit, the elevator car, counterweight and elevator car are on the top floor. The cam and detector for detecting the position of the counterweight and the output value of the detector are converted based on the actual value of the counter clearance between the counterweight and the shock absorber at the initial setting, There is known an elevator counter clearance measuring device including an elevator control computer that outputs the counter clearance (see, for example, Patent Document 1).

従来のエレベータ釣合い錘・調速機ロープ張り車のクリアランス管理測定装置を図７、図８により説明する。各図の（ａ）は釣合い錘クリアランス測定方法を示し、各図の（ｂ）は調速機張り車クリアランス測定方法を示す。
図において、１はエレベータのかごで、昇降路内に立設されたかご用ガイドレールにより案内されて昇降する。２は釣合い錘で、昇降路内に立設された釣合い錘用ガイドレールにより案内されて昇降する。３はかご１と釣合い錘２を連結する主ロープ、４は昇降路底部に設置された釣合い錘用緩衝器、５は調速機ロープ、６は調速機ロープ張り車、７は昇降路ピット床、８ａは釣合い錘用ガイドレールに取り付けられた釣合い錘用センサー、９ａは釣合い錘２に取り付けられ、釣合い錘用センサー８ａにより検出される釣合い錘用検出片である。ａ１は釣合い錘２と釣合い錘用緩衝器４との間の距離であり、一般的に釣合い錘クリアランスと呼ばれる。従来の技術にあっては、保守員が釣合い錘クリアランスａ１を最初に測定し、釣合い錘２に釣合い錘用検出片９ａを取り付け、初回測定時に釣合い錘用センサー８ａの検出位置をエレベータ制御盤（図示せず）に記憶させ、検出位置の変化により、釣合い錘クリアランスａ１の変化を捉えるものであった。
また、ａ２は調速機ロープ張り車６と昇降路ピット床７との間の距離であり、一般的に調速機ロープ張り車クリアランスと呼ばれる。従来の技術にあっては、保守員が調速機ロープ張り車クリアランスａ２を定規などの計測工具を用いて定期的に測定し、調速機ロープ５が伸びた時に、調速機ロープ張り車６が昇降路ピット床７が接触することで好ましくない状況になるのを防止すべく、調速機ロープ張り車ａ２を管理しながら、調速機ロープのメンテナンスを行っていた。なお、図７の（ａ）はかご１が最上階にある時を示しているが、図８の（ａ）はかご１が最下階にある時を示している。また、調速機ロープ張り車クリアランスａ２を測定するには、保守員がエレベータの昇降路ピットに入って作業するため時間を要し、また作業の都度エレベータが走行しないように停止措置を取る必要があり、乗客の利便性を低下させている。 A conventional elevator balance weight / governor rope tension wheel clearance management measuring device will be described with reference to FIGS. (A) of each figure shows the counterweight clearance measuring method, (b) of each figure shows the governor tensioner clearance measuring method.
In the figure, reference numeral 1 denotes an elevator car which is raised and lowered by being guided by a car guide rail standing in the hoistway. Reference numeral 2 denotes a counterweight, which is lifted and lowered by being guided by a counterweight guide rail erected in the hoistway. 3 is a main rope that connects the car 1 and the counterweight 2, 4 is a counterweight buffer installed at the bottom of the hoistway, 5 is a governor rope, 6 is a governor rope tensioner, and 7 is a hoistway pit. The floor 8a is a counterweight sensor attached to the counterweight guide rail, and 9a is a counterweight detection piece attached to the counterweight 2 and detected by the counterweight sensor 8a. a1 is a distance between the counterweight 2 and the counterweight buffer 4 and is generally called a counterweight clearance. In the conventional technique, the maintenance staff first measures the counterweight clearance a1, attaches the counterweight detection piece 9a to the counterweight 2, and sets the detection position of the counterweight sensor 8a at the time of the first measurement to the elevator control panel ( (Not shown), and the change of the counterweight clearance a1 is captured by the change of the detection position.
Moreover, a2 is the distance between the governor rope tensioning vehicle 6 and the hoistway pit floor 7, and is generally called the governor rope tensioning vehicle clearance. In the conventional technology, the maintenance staff regularly measures the governor rope tension vehicle clearance a2 using a measuring tool such as a ruler, and when the governor rope 5 is extended, the governor rope tension vehicle is In order to prevent 6 from coming into an unfavorable situation due to contact with the hoistway pit floor 7, the governor rope has been maintained while managing the governor rope tensioning vehicle a2. 7A shows the time when the car 1 is on the top floor, while FIG. 8A shows the time when the car 1 is on the bottom floor. Moreover, in order to measure the governor rope tension vehicle clearance a2, it takes time for maintenance personnel to enter and work in the elevator hoist pit, and it is necessary to take stop measures so that the elevator does not run every time work is performed. There is a decrease in passenger convenience.

図１において、１はエレベータのかごで、昇降路内に立設されたかご用ガイドレールにより案内されて昇降する。２は釣合い錘で、昇降路内に立設された釣合い錘用ガイドレールにより案内されて昇降する。３はかご１と釣合い錘２を連結する主ロープ、４は昇降路底部に設置された釣合い錘用緩衝器、５は調速機ロープ、６は調速機ロープ張り車、７は昇降路ピット床、８ａは釣合い錘用ガイドレールに取り付けられた釣合い錘用センサー、９ａは釣合い錘２に取り付けられ、釣合い錘用センサー８ａにより検出される釣合い錘用検出片である。ａ１は釣合い錘２と釣合い錘用緩衝器４との間の距離であり、一般的に釣合い錘クリアランスと呼ばれる。
また、８ｂはかご用ガイドレールに取り付けられた調速機ロープ張り車用センサー、９ｂは調速機ロープ５に取り付けられ、調速機ロープ張り車用センサー８ｂにより検出される調速機ロープ張り車用検出片である。ａ２は調速機ロープ張り車６と昇降路ピット床７との間の距離であり、一般的に調速機ロープ張り車クリアランスと呼ばれる。 In FIG. 1, reference numeral 1 denotes an elevator car, which is raised and lowered by being guided by a car guide rail standing in the hoistway. Reference numeral 2 denotes a counterweight, which is lifted and lowered by being guided by a counterweight guide rail erected in the hoistway. 3 is a main rope that connects the car 1 and the counterweight 2, 4 is a counterweight buffer installed at the bottom of the hoistway, 5 is a governor rope, 6 is a governor rope tensioner, and 7 is a hoistway pit. The floor 8a is a counterweight sensor attached to the counterweight guide rail, and 9a is a counterweight detection piece attached to the counterweight 2 and detected by the counterweight sensor 8a. a1 is a distance between the counterweight 2 and the counterweight buffer 4 and is generally called a counterweight clearance.
Reference numeral 8b denotes a governor rope tensioned vehicle sensor attached to the car guide rail, and 9b denotes a governor rope tensioned vehicle sensor attached to the governor rope 5 and detected by the governor rope tensioned vehicle sensor 8b. It is a detection piece for cars. a2 is the distance between the governor rope tensioning vehicle 6 and the hoistway pit floor 7, and is generally called the governor rope tensioning vehicle clearance.

上記釣合い錘用センサー８ａと釣合い錘用検出片９ａは、昇降路下部に設置され、エレベータのかご１が最上階レベルから１００〜２００ｍｍ程度行き過ぎた位置（例えば、ファイナルリミットスイッチが動作せず、かつ釣合い錘クリアランスａ１よりも短い距離）で、釣合い錘用センサー８ａが釣合い錘用検出片９ａを検出できるように取り付けられる。また、釣合い錘用センサー８ａは、釣合い錘用検出片９ａを検出した時、エレベータの制御盤（図示せず）へ信号を出力する。制御盤は釣合い錘用センサー８ａからの信号を受信した時にアラームを出力し、監視センターへ電話回線などを経由して通報する機能を有している。また、月に１回程度、利用者がいない時間帯にエレベータを自動的に最上階レベルから１００〜２００ｍｍ程度行き過ぎた上方位置（例えば、ファイナルリミットスイッチが動作せず、かつ釣合い錘クリアランスａ１よりも短い距離）へ走行させ、ファイナルリミットスイッチが動作する直前で停止させる。その走行行程で釣合い錘用センサー８ａからの検出信号を受信した時、エレベータの制御盤で検出位置を記憶し、アラームを出力する。
これにより、最上階レベル位置で釣合い錘用センサー８ａからの検出信号を受信する場合は、「即調整」とし、最上階レベルより上方の位置で検出信号を受信する場合は、「要点検」という具合に、点検時期・調整内容を事前に準備可能とすることができる。 The counterweight sensor 8a and the counterweight detection piece 9a are installed at the lower part of the hoistway, and the elevator car 1 has passed too much about 100 to 200 mm from the top floor level (for example, the final limit switch does not operate and The counterweight sensor 8a is attached so that the counterweight detection piece 9a can be detected at a distance shorter than the counterweight clearance a1). The counterweight sensor 8a outputs a signal to an elevator control panel (not shown) when the counterweight detection piece 9a is detected. The control panel has a function of outputting an alarm when receiving a signal from the counterweight sensor 8a and notifying the monitoring center via a telephone line or the like. Also, once a month, during the time when there is no user, the elevator automatically goes over the top floor level by about 100 to 200 mm (for example, the final limit switch does not work and the counterweight clearance a1 Travel to a short distance) and stop just before the final limit switch is activated. When a detection signal is received from the counterweight sensor 8a during the travel, the detection position is stored in the elevator control panel and an alarm is output.
Thus, when the detection signal from the counterweight sensor 8a is received at the top floor level position, it is referred to as “immediate adjustment”, and when the detection signal is received at a position above the top floor level, it is referred to as “necessary inspection”. In particular, it is possible to prepare the inspection time and adjustment details in advance.

また、上記調速機ロープ張り車用センサー８ｂと調速機ロープ張り車用検出片９ｂは、昇降路上部に設置され、エレベータのかご１が最下階のレベル位置（図１ｂ参照）で調速機ロープ張り車用センサー８ｂが調速機ロープ張り車用検出片９ｂを検出するように（レベルの手前数１０ｍｍで検出できるように）取り付ける。上記調速機ロープ張り車用センサー８ｂは、調速機ロープ張り車用検出片９ｂを検出した時、エレベータの制御盤（図示せず）へ信号を出力する。制御盤は調速機ロープ張り車用センサー８ｂからの信号を受信した時のかご位置をセンサー検出位置（ｘ１とする）として記憶する機能を有している。また、保守員は初回保守時等に、調速機ロープ張り車クリアランスが良好な状態で、調速機ロープ張り車クリアランスａ２を測定し、次にかご１が最下階レベルにある時に制御盤で算出されるかご位置データを基準値（ｙ１とする）として予め制御盤に設定しておく。そして、最下階へ走行する毎に調速機ロープ５側の調速機ロープ張り車用センサー８ｂが調速機ロープ張り車用検出片９ｂを検出した時のかご位置ｘ１を算出し、予め設定されている基準値ｙ１との差を算出して記憶する。かご１が最下階走行時に、調速機ロープ張り車用センサー８ｂが調速機ロープ張り車用検出片９ｂを検出するように設置するので、調速機ロープ５が伸びるにつれて、センサー検出タイミングが早くなり、検出時のかご位置ｘ１が大きくなるため、調速機ロープ張り車クリアランスの減少量は、調速機ロープ張り車用センサー検出時のかご位置ｘ１と基準値ｙ１により、（ｘ１−ｙ１）／２と算出される。また、制御盤は、調速機ロープ張り車クリアランスの減少量（ｘ１−ｙ１）が予め設定された値を超えた場合にアラームを出力し、監視センターへ電話回線などを経由して通報する機能を有する。   The governor rope tensioning vehicle sensor 8b and the governor rope tensioning vehicle detection piece 9b are installed at the upper part of the hoistway, and the elevator car 1 is adjusted at the level position of the lowest floor (see FIG. 1b). The speed rope rope tension sensor 8b is attached so that the speed governor rope tension car detection piece 9b can be detected (so that it can be detected at a level of 10 mm before the level). When the governor rope tensioning vehicle sensor 8b detects the governor rope tensioning vehicle detection piece 9b, it outputs a signal to an elevator control panel (not shown). The control panel has a function of storing the car position when the signal from the governor rope tension vehicle sensor 8b is received as a sensor detection position (x1). In addition, the maintenance staff measures the governor rope tension vehicle clearance a2 in the state where the governor rope tension vehicle clearance is in good condition at the first maintenance, etc., and then the control panel when the car 1 is at the lowest floor level. The car position data calculated in step 1 is set in advance on the control panel as a reference value (referred to as y1). And every time it travels to the lowest floor, it calculates the car position x1 when the governor rope tensioning vehicle sensor 8b on the governor rope 5 side detects the governor rope tensioning vehicle detection piece 9b, The difference from the set reference value y1 is calculated and stored. When the car 1 is traveling on the lowermost floor, the governor rope tensioned vehicle sensor 8b is installed so as to detect the governor rope tensioned vehicle detection piece 9b. Therefore, as the governor rope 5 extends, the sensor detection timing is increased. Since the car position x1 at the time of detection becomes larger, the reduction amount of the governor rope tension vehicle clearance is determined by (x1−) according to the car position x1 and the reference value y1 at the time of detection of the governor rope tension car sensor. It is calculated as y1) / 2. Also, the control panel outputs an alarm when the reduction amount of the governor rope tension vehicle clearance (x1-y1) exceeds a preset value, and notifies the monitoring center via a telephone line or the like Have

次に、エレベータ釣合い錘・調速機ロープ張り車のクリアランス管理測定装置の動作を図２により説明する。
先ず、ステップＳ１で釣合い錘用センサー８ａからの検出入力信号があるか否かを見る。釣合い錘用センサー８ａからの検出入力信号があれば、かご位置を記憶してアラーム出力を監視センターへ通報する（ステップＳ２）。
次に、ステップＳ３で調速機ロープ張り車用センサー８ｂからの検出入力信号があるか否かを見る。調速機ロープ張り車用センサー８ｂからの検出入力信号があれば、エレベータの制御盤（図示せず）へ信号を出力し、制御盤は調速機ロープ張り車用センサー８ｂからの信号を受信した時のかご位置ｘ１をセンサー検出位置として記憶する（ステップＳ４）。保守員は初回保守時等に、調速機ロープ張り車クリアランスが良好な状態で、調速機ロープ張り車クリアランスａ２を測定し、かご１が最下階レベルにある時に制御盤で算出されるかご位置データを初回測定値ｙ１（基準値）として予め制御盤に設定しておく。そして、かご位置ｘ１と初回測定値ｙ１との差を算出する（ステップＳ５）。この算出結果を良否判定の基準値と比較し（ステップＳ６）、判定結果がＮＧであれば（ステップＳ７）、監視センターに通報する（ステップＳ８）。また、ステップＳ７で判定結果がＯＫであれば、通常サービスに戻る（ステップＳ９）。 Next, the operation of the elevator balance weight / governor rope tension wheel clearance management measuring device will be described with reference to FIG.
First, in step S1, it is checked whether or not there is a detection input signal from the counterweight sensor 8a. If there is a detection input signal from the counterweight sensor 8a, the car position is stored and an alarm output is reported to the monitoring center (step S2).
Next, it is checked in step S3 whether or not there is a detection input signal from the governor rope tensioning vehicle sensor 8b. If there is a detection input signal from the governor rope tension vehicle sensor 8b, it outputs a signal to the elevator control panel (not shown), and the control panel receives the signal from the governor rope tension sensor 8b. The car position x1 at this time is stored as a sensor detection position (step S4). The maintenance staff measures the governor rope tension vehicle clearance a2 in the state where the governor rope tension vehicle clearance is good at the first maintenance, etc., and is calculated by the control panel when the car 1 is at the lowest floor level. The car position data is set in the control panel in advance as the initial measurement value y1 (reference value). Then, the difference between the car position x1 and the initial measurement value y1 is calculated (step S5). This calculation result is compared with a reference value for pass / fail determination (step S6), and if the determination result is NG (step S7), the monitoring center is notified (step S8). If the determination result is OK in step S7, the process returns to the normal service (step S9).

FIG. 3 is a front view showing a configuration of a main part of a clearance management measuring apparatus for elevator counterweight according to Embodiment 2 of the present invention, and FIG. 4 shows sensor detection of the clearance management measuring apparatus for elevator counterweight according to Embodiment 2 of the present invention. FIG. 5 is a front view showing a main part configuration of a clearance management measuring device for an elevator governor rope tensioned vehicle according to Embodiment 2 of the present invention, and FIG. 6 is Embodiment 2 of the present invention. It is a perspective view which shows the structure of the sensor detection part of the clearance management measuring apparatus of the elevator governor rope tension vehicle.

図３、図４は釣合い錘用センサー８ａ、釣合い錘用検出片９ａの具体的な取付例を示し、磁気センサー（光センサーでも良い）と遮蔽板を使用する例である。１０は釣合い錘用ガイドレール、１１は釣合い錘用センサー（磁気センサー）８ａを取り付けるためのセンサー取付腕で、釣合い錘用ガイドレール１０の下部に取り付けられる。センサー取付腕１１は、昇降路ピットで取り付けが可能で、かつ主ロープ３が伸びても釣合い錘２と衝突しない位置で釣合い錘用ガイドレール１０に固定する。釣合い錘用検出片（遮蔽板）９ａは、釣合い錘２の主ロープ３が伸びても釣合い錘用緩衝器４と干渉しない位置に取り付けられ、エレベータのかご１が最上階の手前数１０ｍｍの位置で、釣合い錘２が下方向に通過する時に釣合い錘用検出片（遮蔽板）９ａが釣合い錘用センサー（磁気センサー）８ａを横切るように設置する。釣合い錘用センサー（磁気センサー）８ａからの入力信号は、図１に示すように、最下階の乗場操作盤の下方向呼びボタンの入力（通常は使用しない）を使用して制御盤へ取り込むことにより、配線作業を簡略化することが可能となる。   FIGS. 3 and 4 show specific examples of attachment of the counterweight sensor 8a and the counterweight detection piece 9a, in which a magnetic sensor (or an optical sensor) and a shielding plate are used. Reference numeral 10 is a counterweight guide rail, and 11 is a sensor mounting arm for attaching a counterweight sensor (magnetic sensor) 8a, which is attached to the lower part of the counterweight guide rail 10. The sensor mounting arm 11 can be mounted at the hoistway pit and is fixed to the counterweight guide rail 10 at a position where it does not collide with the counterweight 2 even when the main rope 3 extends. The counterweight detecting piece (shielding plate) 9a is attached at a position where it does not interfere with the counterweight buffer 4 even if the main rope 3 of the counterweight 2 extends, and the elevator car 1 is located at a position several tens of millimeters in front of the top floor. Thus, when the counterweight 2 passes downward, the counterweight detecting piece (shielding plate) 9a is installed so as to cross the counterweight sensor (magnetic sensor) 8a. As shown in FIG. 1, the input signal from the counterweight sensor (magnetic sensor) 8a is input to the control panel using the input of the lower direction call button on the hall control panel on the lowest floor (not normally used). Thus, the wiring work can be simplified.

また、図５、図６は調速機ロープ張り車用センサー８ｂ、調速機ロープ張り車用検出片９ｂの具体的な取付例を示し、磁気センサーと絶縁シールを使用する例である。１２はかご用ガイドレール、１３は調速機ロープ張り車用センサー（磁気センサー）８ｂを取り付けるためのセンサー取付腕で、かご用ガイドレール１２上部に取り付けられる。１４は調速機シーブ又は調速機返し車（ボトム式調速機の場合）である。調速機ロープ張り車用センサー８ｂは、磁気センサーを使用し、昇降路天井付近のかご用ガイドレール１２へセンサー取付腕１３を取り付け、調速機ロープ張り車用センサー８ｂをセンサー取付腕１３に設置する。調速機ロープ張り車用センサー（磁気センサー）８ｂは、図６に示すように、磁気出力部と入力部の間を調速機ロープ５が通過できる構造で、かつ磁気入力が一定量以上になったことを検出した時に内蔵リレーが動作する機能を有するものである。また、調速機ロープ張り車用検出片９ｂは、絶縁素材のシールを調速機ロープ５へ数１０ｍｍ程度巻き付けることにより実現し、エレベータのかご１が最下階の手前数１０ｍｍの位置で、調速機ロープ張り車用センサー（磁気センサー）８ｂから出力する磁気を調速機ロープ張り車用検出片（調速機ロープに巻き付けた絶縁シール）９ｂは、エレベータの走行によって調速機ロープ５が移動しても、昇降路頂部の調速機シーブ又は調速機張り車１４の何れにも接触しない位置に取り付けることにより、調速機ロープ用張り車用検出片（遮蔽板）９ｂが外れることにより、調速機ロープ張り車用センサー（磁気センサー）８ｂで検出できなくなること、又は調速機シーブに絡み付いて回転状態を悪くすることを防止できる。また、調速機ロープ張り車用センサー８ｂからの入力信号は、図１に示すように、最上階乗場操作盤の上方向呼びボタンの入力（通常は使用しない）を使用して制御盤へ取り込むことで、配線作業の簡略化も可能である。   FIGS. 5 and 6 show specific examples of attachment of the governor rope tensioning vehicle sensor 8b and the governor rope tensioning vehicle detection piece 9b, in which magnetic sensors and insulating seals are used. Reference numeral 12 denotes a car guide rail, and reference numeral 13 denotes a sensor attachment arm for attaching a governor rope tension vehicle sensor (magnetic sensor) 8b, which is attached to the upper part of the car guide rail 12. Reference numeral 14 denotes a governor sheave or a governor return wheel (in the case of a bottom-type governor). The sensor 8b for the governor rope tension vehicle uses a magnetic sensor, attaches the sensor attachment arm 13 to the guide rail 12 for the car near the hoistway ceiling, and the sensor 8b for the governor rope tension vehicle to the sensor attachment arm 13. Install. As shown in FIG. 6, the governor rope tensioning vehicle sensor (magnetic sensor) 8b has a structure in which the governor rope 5 can pass between the magnetic output portion and the input portion, and the magnetic input exceeds a certain amount. The built-in relay has a function to operate when it is detected. Further, the governor rope tensioning vehicle detection piece 9b is realized by winding a seal of insulating material around the governor rope 5 about several tens of millimeters, and the elevator car 1 is located at a position several tens of millimeters before the lowest floor, The detection piece for the governor rope tensioned vehicle (insulation seal wrapped around the governor rope) 9b is output from the governor rope tensioned vehicle sensor (magnetic sensor) 8b. Is attached to a position where it does not come in contact with either the governor sheave or the governor tensioning wheel 14 at the top of the hoistway, so that the detection piece (shielding plate) 9b for the governor rope is removed. Accordingly, it is possible to prevent the speed governor rope tension vehicle sensor (magnetic sensor) 8b from being detected, or entangled with the speed governor sheave to deteriorate the rotation state. Further, as shown in FIG. 1, the input signal from the governor rope tension vehicle sensor 8b is input to the control panel using the input of the upper direction call button (not normally used) on the top floor hall operation panel. Thus, the wiring work can be simplified.
