Description

本発明は、エレベーターに関する。   The present invention relates to an elevator.

エレベーターの保守点検には、技術作業員がピット部に侵入して行われる作業とかご上に乗り込んで行われる作業がある。このような保守点検にて行われるかごの位置をピット部進入位置又はかご上搭乗位置に合わせる作業は、従来より技術作業員と共同で保守点検を行う共同作業者を含む少なくとも二人以上で行われ、例えば乗場で待機する技術作業員が乗場ドアのガラス窓や乗場ドアの隙間からかごの停止位置を確認し、かご内に乗車した共同作業者にかごの走行指示を行うことにより、かごをピット部進入位置又はかご上搭乗位置に停止させるようにしていた。そのため、かごを適切な位置に停止させるまで非常に手間がかかっていた。   There are two types of maintenance and inspection of elevators: a work performed by a technical worker entering the pit and a work carried on the car. The work of adjusting the position of the car in such a maintenance inspection to the pit entry position or the boarding position on the car is conventionally performed by at least two persons including joint workers who perform maintenance inspection jointly with technical workers. For example, a technical worker waiting at the landing confirms the stop position of the car from the glass window of the landing door or the clearance between the landing doors, and instructs the collaborators who have entered the car to run the car. The vehicle was stopped at the pit entry position or the boarding position on the car. For this reason, it has been very troublesome to stop the car at an appropriate position.

そこで、通常運転時のモードである通常運転モードと、保守点検を行うためのモードである保守点検モードのいずれかの動作モードで動作し、この動作モードの切り替えをかご内操作盤に設けられたコマンド入力ボタン、行き先階ボタン、扉を開くボタン、及び扉を閉じるボタンを組み合わせて入力することで行うエレベーター装置が提案されている。このエレベーター装置は、保守点検モードで動作する際に、乗り場操作盤に設けられた上ボタン又は下ボタンを操作することにより、かごをピット部進入位置又はかご上搭乗位置に自動で一定距離昇降させることができる。   Therefore, the operation mode of the normal operation mode, which is a mode for normal operation, and the maintenance inspection mode, which is a mode for performing maintenance inspection, are operated, and switching of this operation mode is provided on the operation panel in the car. There has been proposed an elevator apparatus that performs a combination of a command input button, a destination floor button, a door opening button, and a door closing button. When operating in the maintenance / inspection mode, this elevator device automatically moves the car up and down by a certain distance to the pit entry position or the boarding position by operating the upper button or the lower button provided on the landing control panel. be able to.

図１はエレベーターの全体構成を示す図である。本発明に係る乗り場保守運転の実施形態は、例えば図１に示すように建物の昇降路８内に設けられたエレベーターに適用される。このエレベーターは、昇降路８内を昇降するかご６と、このかご６に対して相対的に昇降する釣合い錘９と、かご６を昇降させる巻上機４と、巻上機４に取り付けられかご６の昇降距離を計測するエンコーダ５と、巻上機を介してかご６と釣り合い錘を吊り下げる主ロープ１０と、巻上機を含む昇降路１内の機器の動作を制御する制御盤３とを有している。なお、かご６の昇降距離計測はガバナに取り付けられたエンコーダでも可とする。なお、図では制御盤３や巻上機４を昇降路下部に置く構造としているが、昇降路上部に置く構造としてもよい。   FIG. 1 is a diagram showing an overall configuration of an elevator. The embodiment of the landing maintenance operation according to the present invention is applied to an elevator provided in a hoistway 8 of a building, for example, as shown in FIG. The elevator includes a car 6 that moves up and down in a hoistway 8, a counterweight 9 that moves up and down relative to the car 6, a hoisting machine 4 that raises and lowers the car 6, and a car that is attached to the hoisting machine 4. An encoder 5 that measures the lifting distance of 6, a main rope 10 that suspends a counterweight from the car 6 via a hoisting machine, and a control panel 3 that controls the operation of equipment in the hoistway 1 including the hoisting machine, have. In addition, the raising / lowering distance measurement of the cage | basket | car 6 is also possible with the encoder attached to the governor. In the figure, the control panel 3 and the hoisting machine 4 are arranged at the lower part of the hoistway, but may be arranged at the upper part of the hoistway.

エレベーターは、かご６内に設けられた運転盤７と、昇降路８内のかご上とピット部に設けられ、制御装置３及びかご２の運転を停止させる停止スイッチ２とを備えている。運転盤７は、図示されないが、かごドアを開く開釦と、かごドアを閉じる閉釦と、かご６の行先として目的階を登録するかご呼び釦と、後述の保守運転モードの入力を行う保守スイッチとを含んでいる。   The elevator includes an operation panel 7 provided in the car 6, and a stop switch 2 provided on the car in the hoistway 8 and on the pit portion to stop the operation of the control device 3 and the car 2. Although not shown in the figure, the operation panel 7 is an open button for opening the car door, a close button for closing the car door, a car call button for registering the destination floor as the destination of the car 6, and maintenance for inputting a maintenance operation mode described later. Includes a switch.

この保守スイッチは、運転盤７の下部に配置され、作業員以外の人に操作されないようカバーで覆われたボックス内に格納されている。また、エレベーターは乗り場に設けられ、かご６を呼び寄せるために入力される乗り場釦１を有している。   The maintenance switch is disposed in a lower part of the operation panel 7 and is stored in a box covered with a cover so as not to be operated by a person other than an operator. The elevator is provided at the landing and has a landing button 1 that is input to call the car 6.

本実施形態では、エレベーターの動作モードとして、各階の乗場へ通常の速度で走行させる通常モード、かご６を通常よりも低速で走行させる前述の保守運転モード、かご６上でかご６を通常よりも低速で走行させるかご上保守運転モード、ピット部でかご６を通常よりも低速で走行させるピット保守運転モードがある。   In the present embodiment, as the operation mode of the elevator, the normal mode for traveling to the landing on each floor at a normal speed, the above-described maintenance operation mode for traveling the car 6 at a lower speed than normal, and the car 6 on the car 6 than normal. There is a car maintenance operation mode for running at a low speed and a pit maintenance operation mode for running the car 6 at a lower speed than usual in the pit portion.

制御盤３は、例えば図１の昇降路８の底部すなわちピット部に設けられ、図示されないが記憶された規定距離昇降させる規定距離走行部と、乗り場釦１の操作によって任意の位置に昇降させるかご位置調整部と、かご６が乗り場から昇降した距離を計測する昇降距演算部と、かご６が乗り場から昇降した距離を規定距離として記憶する規定距離記憶部とを有している。   The control panel 3 is provided, for example, at the bottom of the hoistway 8 shown in FIG. A position adjustment unit, an elevating distance calculating unit that measures the distance that the car 6 has moved up and down from the landing, and a specified distance storage unit that stores the distance that the car 6 has moved up and down from the landing as a specified distance.

規定距離走行部は、かご６内の運転盤７によって保守運転モードが設定され、乗り場釦が特殊操作されたとき、ドア閉信号を受け乗り場に停止していたかご６のドアが閉まり、自動で予め記憶されている規定距離走行させるようにしている。   When the maintenance operation mode is set by the operation panel 7 in the car 6 and the landing button is specially operated, the specified distance traveling unit receives the door closing signal and the door of the car 6 stopped at the landing is automatically closed. A predetermined distance stored in advance is used.

かご位置調整部は、前述の規定距離走行後も技術作業者がかご６を任意の位置に昇降させたい場合、乗り場釦１の操作によりかご６位置を微調整できるようにしている。   The car position adjustment unit allows the position of the car 6 to be finely adjusted by operating the landing button 1 when the engineer wants to raise or lower the car 6 to an arbitrary position even after traveling the specified distance.

昇降距離演算部は、この巻上機４の回転数に応じたパルスを出力させるエンコーダ５と、このエンコーダ５のかご６の乗場からの昇降距離を演算する。   The lift distance calculation unit calculates the lift distance from the landing of the car 5 of the encoder 5 that outputs a pulse corresponding to the rotational speed of the hoist 4 and the car 5.

規定距離記憶部は、前述の規定距離走行に加え、技術作業者がかご６を微調整した後の昇降距離を昇降路８内の停止スイッチ２が押されたタイミングで記憶する。これにより次回から自動で記憶された距離昇降するようにしている。この規定距離記憶部は単なる記憶媒体ではなく、記憶媒体と当該記憶媒体に記録させる処理機能を有している。   In addition to the above-mentioned prescribed distance travel, the prescribed distance storage unit stores the lift distance after the technician finely adjusts the car 6 at the timing when the stop switch 2 in the hoistway 8 is pressed. As a result, the stored distance is automatically raised and lowered from the next time. The specified distance storage unit is not a mere storage medium but has a storage medium and a processing function for recording on the storage medium.

次にかご上保守点検モードでの動作処理を図２のフローチャートを用いて説明する。本実施形態では、エレベーターのかご６を中間階または最上階に停止させ、運転盤７のボックス内に格納されている保守スイッチが投入され(Ｓ１)、保守運転モードに設定することで(Ｓ２)、技術作業員以外はエレベーターを操作できない状態にする。   Next, the operation process in the car maintenance / inspection mode will be described with reference to the flowchart of FIG. In the present embodiment, the elevator car 6 is stopped on the intermediate floor or the top floor, the maintenance switch stored in the box of the operation panel 7 is turned on (S1), and the maintenance operation mode is set (S2). Make sure that only the technical workers can operate the elevator.

次に、技術作業員によって乗り場釦が特殊操作され(Ｓ３)、乗り場釦１を点滅させることによって乗り場保守運転モードの設定が完了した(Ｓ４)ことを知らせる。そして、乗り場下釦が一定時間以上押されると(Ｓ５)、ドア閉じ信号によりエレベーターの扉が閉まり(Ｓ６)、制御盤３の規定距離走行部に信号が入力される。これにより、信号を受信した規定距離走行部は規定距離記憶部に記憶された距離かごを降させ、かごを停止する(Ｓ７)。また、規定距離走行部から出力された信号が前述の昇降距離演算部に入力され、エレベーターの走行開始からエンコーダ５の出力信号に基づいて昇降距離を演算する。規定距離走行部の信号により、自動走行して停止した位置がかご上乗り込みに適さなかった場合は(Ｓ８)、技術作業員による乗り場釦１の操作によりかご位置調整部に信号が入力され、かご位置を微調整して適切な位置へ昇降させる(Ｓ９)。技術作業員によって乗り場側の扉が開かれ、かご上停止スイッチ２が押されたタイミングで(Ｓ１０)規定距離記憶部に信号が入力され、最終的な昇降距離が規定距離記憶部に記憶される(Ｓ１１)。これにより次回から自動的にＳ１１で記憶された距離昇降させることが可能となる。なお、規定距離記憶部には昇降距離ではなく、昇降路内のかご位置を記憶して、指定された位置で停止する様にしてもよい。   Next, the landing button is specially operated by the technical worker (S3), and the landing button 1 blinks to notify that the setting of the landing maintenance operation mode is completed (S4). When the landing down button is pressed for a predetermined time or longer (S5), the door of the elevator is closed by a door closing signal (S6), and a signal is input to the specified distance traveling portion of the control panel 3. As a result, the specified distance traveling unit that has received the signal lowers the distance car stored in the specified distance storage unit and stops the car (S7). In addition, a signal output from the specified distance travel unit is input to the above-described lift distance calculation unit, and the lift distance is calculated based on the output signal of the encoder 5 from the start of elevator travel. If the position where the vehicle has automatically stopped and stopped due to the signal from the specified distance traveling unit is not suitable for entering the car (S8), a signal is input to the car position adjusting unit by operating the landing button 1 by a technical worker, The position is finely adjusted and moved up and down to an appropriate position (S9). A signal is input to the specified distance storage unit at the timing when the landing door is opened by the technical worker and the car stop switch 2 is pressed (S10), and the final lift distance is stored in the specified distance storage unit. (S11). This makes it possible to automatically move up and down the distance stored in S11 from the next time. The specified distance storage unit may store the car position in the hoistway instead of the elevating distance and stop at the designated position.

以上をもって、かご上保守点検モードの動作処理が終了する。なお、上述した本実施形態は、本発明を分かり易く説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定されるものではない。また、ある実施形態の構成の一部を他の実施形態の構成に置き換えることが可能である。   The operation process in the car maintenance / inspection mode is thus completed. In addition, this embodiment mentioned above was described in detail in order to demonstrate this invention easily, and is not necessarily limited to what is provided with all the demonstrated structures. A part of the configuration of one embodiment can be replaced with the configuration of another embodiment.
