When disconnection is measured, the terminals in the one of the connection parts are detached, and a terminal of a measuring instrument 13 is connected to individual doubled core wires so as to confirm the disconnection state. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明はエレベーターにおけるテールコードの断線測定方法に関する。 The present invention relates to a method for measuring a break in a tail cord in an elevator.

従来、この種の方法としては、制御盤とテールコードとの接続部及び、テールコードと乗りかごとの接続部の両方を外し、測定器の一方の端子をテールコードの制御盤側の端子に、他方の端子をテーブルコードの乗りかご側の端子にそれぞれ接続して各芯線の断線の有無を確認することが提案されている（特許文献１参照）。
特開昭６２−３１６８１号公報（第２頁左上欄第５行〜右上欄第１６行） Conventionally, this method has been to remove both the connection between the control panel and the tail cord and the connection between the tail cord and the carriage, and use one terminal of the measuring instrument as the terminal on the control panel side of the tail cord. It has been proposed to connect the other terminal to a car-side terminal of the table cord and check whether or not each core wire is disconnected (see Patent Document 1).

上記従来の方法においては、測定器の端子をテールコードの制御盤側端子と乗りかご側端子とに接続する必要がある。そのため、制御盤とテールコードとの接続部及びテールコードと乗りかごとの接続部の両方を外さなければならない。また、制御盤は通常機械室に設置され、乗りかごは昇降路内に位置し、互いに離れているため測定器の端子の接続は離れた場所で行うこととなり２人と作業となる。さらに、複数本の芯線について２人の作業者が連携して接続換えしながら断線状態を確認するのは複数な作業で長時間かかることになる。 In the above conventional method, it is necessary to connect the terminals of the measuring instrument to the control panel side terminal and the car side terminal of the tail cord. Therefore, both the connection part of the control panel and the tail cord and the connection part of the tail cord and the car must be removed. In addition, the control panel is usually installed in the machine room, and the car is located in the hoistway and is separated from each other. Therefore, the terminals of the measuring device are connected in a remote place, and work with two people. Furthermore, it takes a long time for a plurality of operations to check the disconnection state while two workers cooperate and change connections for a plurality of core wires.

本発明の主な目的は、テールコードの一方の端子だけ外せばテールコード芯線の断線状態を確認できるエレベーターにおけるテールコードの断線測定方法を提供することにる。 A main object of the present invention is to provide a method for measuring a break in a tail cord in an elevator that can confirm a break state of a tail cord core wire by removing only one terminal of the tail cord.

本発明の他の目的は、１つの場所でテールコードの断線状態を確認できるエレベーターにおけるテールコードの断線測定方法を提供することにある。 Another object of the present invention is to provide a method for measuring the breakage of a tail cord in an elevator that can confirm the state of breakage of the tail cord at one place.

上記目的は、制御盤とテールコードとの接続部、及びテールコードと乗りかごとの接続部の少なくとも一方を着脱可能な端子で統合し、制御盤と乗りかごとのテーブルコード芯線による接続を１つの信号に対して２系統の芯線で接続する２重化接続としておくとともに、断線測定の際には前期一方の接続部の端子を外し、２重化された芯線のそれぞれに測定器の端子を接続することを特徴とするエレベーターにおけるテールコードの断線測定方法により達成される。 The purpose is to integrate at least one of the connection part between the control panel and the tail cord and the connection part between the tail code and the car with a detachable terminal, and connect the control panel and the car with a table cord core wire. In addition to a duplex connection that connects two signals to two signals, the terminal of one of the previous period is removed when disconnection is measured, and a measuring instrument terminal is connected to each of the duplexed core wires. This is achieved by a method for measuring the breakage of a tail cord in an elevator characterized by connecting.

本発明によれば、テールコードの一方の端子だけ外せばテールコード芯線の断線状態を確認できるエレベーターにおけるテールコードの断線測定方法を提供することができる。 According to the present invention, it is possible to provide a tail cord disconnection measuring method in an elevator that can confirm the disconnection state of the tail cord core wire by removing only one terminal of the tail cord.

また、１つの場所でテールコードの断線状態を確認できるエレベーターにおけるテールコードの断線測定方法を提供することができる。 In addition, it is possible to provide a tail cord breakage measuring method in an elevator that can check the tailcord breakage state at one place.

以下に発明の一実施形態を図１〜図３により説明する。図１に示すようにエレベーターは、機械室に設置された制御盤１、複数の階床にわたって形成された昇降路２内を昇降するもので、主ロープ３を介して連結されている乗りかご４及びつり合いおもり５と、主ロープ３の途中に係合し、主ロープ３を介して乗りかご４及びつり合いおもり５を相反する方向に移動させるための巻き上げ機６と、端部が前記制御盤１と乗りかご４とに接続集合端子（ＭＬＣ）７，８，９，１０を介して接続されたテールコード１１とを備えている。前記テールコード１１は、十数本の芯線１１ａ〜１１ｎが内蔵され各芯線１１ａ〜１１ｎを通じて制御盤１と乗りかご４間で信号の授受を行うようになっている。ＭＬＣ７，８は同じ端子配列を有する構成のもので、テールコード１１に接続されているＭＬＣ端子８Ａ、このＭＬＣ端子８Ａに結合するＭＬＣ端子８Ｂ、制御盤１に接続されているＭＬＣ端子７Ｂ、このＭＬＣ端子７Ｂに結合するＭＬＣ端子７Ａから構成されている。そして、ＭＬＣ端子８ＢとＭＬＣ端子７Ａとは、ＭＬＣ端子８Ｂの２つの端子８ｂ１、８ｂ２とＭＬＣ端子７Ａの１つの端子７ｂ１、同様に端子８ｂ３、８ｂ４と端子７ｂ３、端子８ｂ５、８ｂ６と端子７ｂ５がそれぞれ信号線で接続されている。乗りかご４側のＭＬＣ９，１０も同様の接続となっている。このように、制御盤１からの１つの信号線に対して、テールコード１１内では２本の芯線、乗りかご４の器具ボックスには１本の信号線で接続される。すなわち１本の信号線に対してテールコード１１の部分が２本の芯線とした２重化接続となっている。次にテールコードの芯線の断線有無の確認方法を図３により説明する。乗りかご４を任意の階床、例えば最上階に停止し、運転休止状態とし電源を遮断する。次に機械室内の制御盤１付近のＭＬＣ端子８ＡとＭＬＣ端子８Ｂとの結合を解除（離す）してＭＬＣ端子８ＡにＭＬＣ端子１２Ｂを介して断線測定器１３を接続する。断線測定器１３内には高度なテスター１３Ａ、測定対象を選択する切り替えスイッチ１３Ｂを内蔵しており、電極線１３Ｘ、１３Ｙが芯線１１ａと芯線１１ｂ、芯線１１ｃと芯線１１ｄ、芯線１１ｍと芯線１１ｎにそれぞれ接続されるように切り替え、芯線１１ａと芯線１１ｂ間、芯線１１ｃと芯線１１ｄ間、芯線１１ｍと芯線１１ｎ間に電流を流して断線状況を順次確認していく。芯線１１ａ〜心線１１ｎの断線状況の測定確認が終了したら、ＭＬＣ端子８ＡにＭＬＣ端子１２Ｂとの結合を解除し、ＭＬＣ端子８Ｂを接続し通常状態に復帰する。 An embodiment of the present invention will be described below with reference to FIGS.

And a tail cord 11 connected to the car 4 via connection collective terminals (MLC) 7, 8, 9, 10. The tail cord 11 includes ten or more core wires 11a to 11n, and transmits and receives signals between the control panel 1 and the car 4 through the core wires 11a to 11n. The MLCs 7 and 8 have the same terminal arrangement. The MLC terminal 8A connected to the tail cord 11, the MLC terminal 8B coupled to the MLC terminal 8A, the MLC terminal 7B connected to the control panel 1, The MLC terminal 7A is coupled to the MLC terminal 7B. The MLC terminal 8B and the MLC terminal 7A include two terminals 8b1 and 8b2 of the MLC terminal 8B and one terminal 7b1 of the MLC terminal 7A, similarly, terminals 8b3 and 8b4 and terminals 7b3, terminals 8b5 and 8b6 and terminals 7b5. Each is connected with a signal line. The MLCs 9 and 10 on the car 4 side have the same connection. As described above, two signal wires are connected to one signal line from the control panel 1 in the tail cord 11, and one signal line is connected to the appliance box of the car 4. In other words, the tail cord 11 has a duplex connection with two core wires for one signal line. Next, a method for confirming whether the tail cord core wire is broken will be described with reference to FIG. The car 4 is stopped on an arbitrary floor, for example, the top floor, the operation is stopped, and the power is shut off. Next, the coupling between the MLC terminal 8A and the MLC terminal 8B near the control panel 1 in the machine room is released (released), and the disconnection measuring device 13 is connected to the MLC terminal 8A via the MLC terminal 12B. The disconnection measuring instrument 13 includes an advanced tester 13A and a changeover switch 13B for selecting a measurement target. The electrode wires 13X and 13Y are connected to the core wire 11a and the core wire 11b, the core wire 11c and the core wire 11d, and the core wire 11m and the core wire 11n. It switches so that each may be connected, an electric current is sent between core wire 11a and core wire 11b, between core wire 11c and core wire 11d, and between core wire 11m and core wire 11n, and a disconnection situation is checked one by one. When the measurement confirmation of the disconnection state of the core wires 11a to 11n is completed, the MLC terminal 8A is disconnected from the MLC terminal 12B, and the MLC terminal 8B is connected to return to the normal state.
