Description

【０００１】
【発明の属する技術分野】
本発明はエレベーターの制御装置に関する。
【０００２】
【従来の技術】
エレベーター昇降路内のピットから手の届かない範囲の機器を点検する場合は点検作業者の足場確保のため点検作業台が必要である。しかし、昇降路内は乗りかごが昇降するものであり前記作業台を固定的に設置しておくと乗りかごと衝突し機器破損となるため点検作業台は固定的に設置せず折り畳み式とし、エレベーター運転中は折り畳んで収納し、点検作業時のみ組立て設置する構成としている。
【０００３】
このような構成で、点検作業台を組立て設置している状態で万が一エレベーターが走行すると乗りかごと点検作台が衝突し、機器破損につながる。また、作業台上で点検中であれば作業者の負傷につながる。
【０００４】
このような機器破損や作業者の負傷を防止するためには作業台が設置されている状態ではエレベーターを停止状態にする必要がある。従来においては作業台の設置又は収納状態を検出するスイッチを設けこのスイッチの接点信号により、エレベーターを停止、または運転に切り替えていた。
【０００５】
また、作業台でなくかご上の転落防止用手すりを固定的に取付けられず折り畳み式にしたものもある。
【０００６】
【発明が解決しようとする課題】
本発明は、機器破損を防止することの出来る制御装置点検用点検台を備えたエレベーター装置を提供することを課題とする。
【０００７】
【課題を解決するための手段】
本発明は、上記課題を解決するために、昇降路内にエレベーターの制御装置、及び制御装置点検用で折り畳み式の点検作業台を配置し、前記制御装置が、乗りかごの移動経路と昇降路壁の間に位置しており、前記制御装置を点検しないときは、点検作業台の踏み台を下方へ回転させて、前記制御装置の下方であって前記制御装置の厚さ方向の鉛直投影内に前記点検作業台を折り畳み収納し、昇降路内の他機器と干渉しない構成とした。
【０００８】
【発明の実施の形態】
以下、本発明の一実施形態を図１を用いて説明する。
【０００９】
図１において１はエレベーターの昇降路、２は制御盤、３は点検作業台であり３ａの踏み台、３ｂの踏み台支え、３ｃのベースからなる。４はケーブルであり、Ｄ部で３ｃのベースに固定され、先端には５のコネクタ（プラグ）が接続される。他端は２の制御盤に接続される。６は踏み台に固定されたコネクタ(キャップ）であり本図１の如く作業台が設置状態であれば５と６のコネクタは接続が不可能である。７は乗りかごであり、作業台設置のまま昇降すれば乗りかごと作業台とが干渉することを示している。８はバッファである。
【００１０】
作業台を収納する際は３ａの踏み台を一旦持ち上げ、３ｂの踏み台支えを３ｃのベースから外す。これで３ａの踏み台が支点Ａを中心に回転可能となり、３ｂの踏み台支えが支点Ｂを中心に回転可能となり図２の如く収納できる。またこの状態ではじめて踏み台側のコネクタとベース側のコネクタがの位置関係が最短となりコネクタの接続が可能となる。
【００１１】
次に図３は本発明の一実施形態を示す電気回路図である。
【００１２】
図３において２１はエレベーターの運転、停止を切り替えるリレーであり、点検作業台のコネクタ５，６を接続している場合はリレーがＯＮし、エレベーター走行可能、コネクタが外れている場合はリレーがＯＦＦし、エレベーター停止となる。
【００１３】
上記の構成のエレベーターにおいて、制御盤の保守点検時は作業台を設置、組立てるが、前記の如くコネクタを外さなければ作業台を組立てられない構成となっているため、コネクタの取外しを忘れることはなく、エレベーターが運転することはない。また、収納の際も作業台を折りたたみ収納し、コネクタを接続するまで運転リレーはＯＮしないので収納を忘れてもエレベーターが運転することはない。以上により、作業台設置時のコネクタの取外しによってエレベーターが停止状態となり、機器破損や作業者の負傷を防止することが出来る。
このように、制御盤点検時に設置する点検台に収納時のみ接続可能なコネクタを設け、点検台設置時はコネクタを外すことにより作業台の設置又は収納状態を検出するスイッチを不要とし、制御装置の低コスト化と点検作業者の安全、機器破損防止を図ることが出来る。
【００１４】
【発明の効果】
本発明によれば、機器破損を防止することの出来る制御装置点検用点検台を備えたエレベーター装置を提供することが可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to an elevator control device.
[0002]
[Prior art]
When inspecting equipment that is out of reach from the pit in the elevator hoistway, an inspection workbench is required to secure a foothold for the inspection worker. However, in the hoistway, the car moves up and down, and if the work table is fixedly installed, it collides with the car and damages the equipment, so the inspection work table is not fixedly installed and is foldable. The elevator is folded during storage and is assembled and installed only during inspection work.
[0003]
With such a configuration, if the elevator travels in a state where the inspection work table is assembled and installed, the car and the inspection work table collide with each other, leading to equipment damage. Moreover, if it is inspecting on a work bench, it will lead to an injury of an operator.
[0004]
In order to prevent such equipment damage and worker injury, it is necessary to stop the elevator in a state where the work table is installed. Conventionally, a switch for detecting the installation or storage state of the workbench is provided, and the elevator is stopped or switched to operation by a contact signal of this switch.
[0005]
In addition, there is a folding type which is not fixedly attached to the handrail for preventing the fall on the cage but the work table.
[0006]
[Problems to be solved by the invention]
This invention makes it a subject to provide the elevator apparatus provided with the inspection stand for control apparatus inspection which can prevent apparatus failure.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, the present invention arranges an elevator control device in a hoistway, and a folding inspection worktable for checking the control device, and the control device moves the moving path of the car and the hoistway. When the control device is not inspected, located between the walls, rotate the stepping platform of the inspection work table downward, and within the vertical projection in the thickness direction of the control device below the control device. The inspection workbench is folded and stored so as not to interfere with other devices in the hoistway.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIG.
[0009]
In FIG. 1, reference numeral 1 denotes an elevator hoistway, 2 denotes a control panel, 3 denotes an inspection work table, which includes a 3a step platform, a 3b step support, and a 3c base. Reference numeral 4 denotes a cable, which is fixed to the base of 3c at the D portion, and a connector (plug) of 5 is connected to the tip. The other end is connected to the control panel 2. Reference numeral 6 denotes a connector (cap) fixed to the platform, and if the work table is installed as shown in FIG. 1, the connectors 5 and 6 cannot be connected. Reference numeral 7 denotes a car, which indicates that the car and the work table interfere with each other when the work table is set up and down. 8 is a buffer.
[0010]
When storing the work table, the step 3a is once lifted, and the step 3b support is removed from the base 3c. As a result, the step 3a can be rotated about the fulcrum A, and the step 3b can be rotated about the fulcrum B and can be stored as shown in FIG. Also, in this state, the positional relationship between the footboard side connector and the base side connector is the shortest and the connector can be connected.
[0011]
Next, FIG. 3 is an electric circuit diagram showing an embodiment of the present invention.
[0012]
In FIG. 3, 21 is a relay that switches between operation and stop of the elevator. When the connectors 5 and 6 of the inspection work table are connected, the relay is ON, the elevator can run, and when the connector is disconnected, the relay is OFF. Then, the elevator stops.
[0013]
In elevators of the above construction, when the control panel of the maintenance the installation the platform, assembling, but since that is configured not assembled the platform unless remove the above as connectors, forgetting the removal of the co-next-data There is no such thing as an elevator. In addition, even when storing, the work table is folded and stored, and the operation relay is not turned on until the connector is connected. Therefore, even if the storage is forgotten, the elevator will not operate. As described above, the elevator is stopped by removing the connector when the workbench is installed, and it is possible to prevent damage to the equipment and injury to the operator.
In this way, a connector that can be connected only during storage is provided on the inspection table that is installed at the time of inspection of the control panel, and when the inspection table is installed, the connector is removed to eliminate the need for a switch for detecting the installation or storage state of the work table. Cost reduction, safety of inspection workers, and prevention of equipment damage.
