Description

【０００１】
【発明の属する技術分野】
本発明は、トロリ線の摩耗模擬試験装置に係り、特に、電気鉄道用の溝付きトロリ線の摩耗模擬試験装置に関するものである。
【０００２】
【従来の技術】
トロリ線は、導電性が良好で、引張荷重が大きく、かつ、耐摩耗性に優れていることから、電気鉄道の給電架線やクレーンのワイヤなどに多用されている。
【０００３】
電気鉄道の給電架線に用いられるトロリ線は、図２に示すように、両側部に溝２２，２２を有する溝付きトロリ線２１である。このトロリ線２１は電車が通過する際にパンタグラフと摺動するが、この摺動の繰り返しによりトロリ線２１に摩耗が生じる。摩耗が進行すると、トロリ線２１の強度が低下して断線に至るおそれがある。
【０００４】
このため、図３に示すように、溝付きトロリ線本体（以下、トロリ線本体と示す）３２の大弧面部３３の摩耗限度位置（摩耗限度線Ａ−Ａ）に挿入溝３４ａ，３４ｂを形成し、その挿入溝３４ａ，３４ｂに摩耗を検知するための検知線３５，３５を挿入した検知線入りトロリ線３１が用いられている。
【０００５】
このトロリ線３１を用いた摩耗検知システムは、先ず、トロリ線本体３２の摩耗が進行することで検知線３５，３５が露出し、次に、摩耗が更に進行して検知線３５，３５の絶縁被覆層等が削られて導体が露出し、この導体とトロリ線本体が接触して導通（又は断線）することで、検知を行っている。このトロリ線３１において、架線中の摩耗による検知の有無を検証し、摩耗検知システムの有効性を確認することは、トロリ線３１の構造等を決定する重要な因子であることから、実際に架線する前に、摩耗を模擬した試験を行う必要がある。
【０００６】
図４に示すように、従来の摩耗模擬試験装置４１は、円板状の固定装置４２の外周部に、取付け金具４３を介して、試験用トロリ線４４を巻き付けた後、固定装置４２を一定速度で回転させながら、摺動板４５をトロリ線４４に押し付けて摩耗させ、一定回転ごとのトロリ線４４又は摺動板４５の摩耗量の測定を行っている。
【０００７】
【発明が解決しようとする課題】
ところで、この試験装置４１において、図３に示したトロリ線３１を用いた場合、試験中は検知線３５，３５もトロリ線３１と共に回転するため、検知線３５，３５の両端部を検知線特性の変化・変動を測定する外部測定器（図示せず）に接続させておくことはできない。また、通電しながら試験を行うと、回転に伴うノイズにより摩耗検知ができない。これらの理由等により、摩耗による検知線特性、即ち摩耗限界に達した際の絶縁特性又は通信特性の連続的な検証を行うことができないことから、検知線特性の変動を検証するたびに回転を停止させる必要があった。つまり、試験装置４１においては、摩耗による検知線特性の変動を連続的に測定・検知（検証）することができないという問題があった。
【０００８】
また、トロリ線４４に対する摺動板４５の押し付けは、スプリング４６を用いて一定荷重で押圧していることから、トロリ線を実際に架線して使用している際に生じる通電アーク摩耗（パンタグラフの摺動板がトロリ線から離線した際に発生するアークによる摩耗）を模擬試験することができないという問題があった。
【０００９】
以上の事情を考慮して創案された本発明の目的は、通電アーク摩耗を模擬試験可能で、また、検知線入りトロリ線の摩耗による検知線特性の変化を連続的に測定・検知できるトロリ線の摩耗模擬試験装置を提供することにある。
【００１０】
【課題を解決するための手段】
上記目的を達成すべく本発明に係るトロリ線の摩耗模擬試験装置は、トロリ線と摺動板を摺動させてトロリ線の摩耗具合いを模擬試験する装置において、直線状に配置・固定したトロリ線に当接する摺動板と、その摺動板をトロリ線の長手方向に往復移動させる第１往復移動手段と、摺動板に接続して設けられ、トロリ線に対して摺動板を離間・当接自在に往復移動させる第２往復移動手段とを備えたものである。
【００１１】
また、上記各往復移動手段の内の少なくとも第２往復移動手段に、その往復移動タイミングを調節する調節手段を接続してもよい。
【００１２】
また、上記トロリ線が、検知線入りトロリ線であってもよい。
【００１３】
以上の構成によれば、通電アーク摩耗を模擬試験することができ、また、検知線入りトロリ線の摩耗による検知線特性の変化を連続的に測定・検知することができる。
【００１４】
【発明の実施の形態】
以下、本発明の好適一実施の形態を添付図面に基いて説明する。
【００１５】
第１の実施の形態に係るトロリ線の摩耗模擬試験装置の概略図を図１に示す。なお、図２，図３と同様の部材には同じ符号を付している。
【００１６】
図１に示すように、本実施の形態に係るトロリ線の摩耗模擬試験装置１１は、天井１２等に取付け金具１３を介して直線状に配置・固定されたトロリ線３１と、そのトロリ線３１と当接する摺動板１８と、その摺動板１８をトロリ線３１に一定圧力で押し付ける押し付け金具（押圧手段）１７と、床面１４等に固定して設けられ、摺動板１８及び押し付け金具１７をトロリ線３１の長手方向に往復移動させる第１シリンダ（第１往復移動手段）１５と、押し付け金具１７に接続して設けられ、トロリ線３１に対して摺動板１８を離間・当接自在に往復移動させる第２シリンダ（第２往復移動手段）１６とを備えたものである。
【００１７】
トロリ線３１の溝３４ａ，３４ｂには検知線３５，３５が挿入されているが（図３参照）、この検知線３５，３５は所定長さの１本の検知線をループ状に折り返して挿入配置したものであり、検知線の両端末は、検知線特性を常時観測・測定する測定器２０に接続されている。
【００１８】
押し付け金具１７はスプリング等の押圧部材（図示せず）を有しており、この押圧部材により、摺動板１８はトロリ線３１に常に一定圧力で押し付けられるため、摺動板１８をスライドさせた時に、摺動板１８とトロリ線３１とが確実に当接することになる。
【００１９】
第１シリンダ１５及び第２シリンダ１６は、それぞれ本体部１５ａ，１６ａ、ピストン部材１５ｂ，１６ｂ、レール部材１５ｃ，１６ｃとで構成される。第１シリンダ１５のピストン部材１５ｂは、第２シリンダ１６の本体部１６ａと接続されており、ピストン部材１５ｂの伸縮に伴って第２シリンダ１６の本体部１６ａが第１シリンダ１５のレール部材１５ｃに沿ってスライドする。また、第２シリンダ１６のピストン部材１６ｂは、押し付け金具１７と接続されており、ピストン部材１６ｂの伸縮に伴って押し付け金具１７が第２シリンダ１６のレール部材１６ｃに沿ってスライドする。さらに、レール部材１５ｃはトロリ線３１の長手方向（図１中では左右方向）に沿って配置され、また、レール部材１６ｃはトロリ線３１の長手方向と垂直な方向（図１中では上下方向）に沿って配置される。ここで、各シリンダ１５，１６は、空圧制御又は油圧制御のどちらであってもよい。また、本実施の形態においては、第１及び第２往復移動手段として、第１及び第２シリンダ１５，１６を用いた場合について説明したが、摺動板１８を、トロリ線３１の長手方向に、また、トロリ線３１に対して離間・当接自在に往復移動できるものであれば、特に限定するものではない。
【００２０】
第１シリンダ１５及び第２シリンダ１６による往復移動距離は、電光式非接触センサなどの位置センサ（図示せず）により調整し、また、各シリンダ１５，１６の往復移動速度は、空気（又は油）の供給圧力又は速度制御弁により調整する。
【００２１】
各シリンダ１５，１６のシリンダ本体部１５ａ，１６ａには、それらの駆動タイミングを調節する調節装置（調節手段）１９がライン１９ａ，１９ｂを介して接続されている。この調節装置１９としては、各シリンダ１５，１６の駆動タイミングを調節できるものであれば、特に限定するものではない。また、本実施の形態においては、調節装置１９が両シリンダ１５，１６の駆動タイミングを調節する場合について説明したが、調節装置１９は、第２シリンダ１６の駆動タイミングのみを調節するものであってもよい。
【００２２】
摺動板１８は給電ライン１０ａを介して給電用電源１０と、また、トロリ線３１は給電ライン１０ｂを介して給電用電源１０と接続されており、摺動板１８とトロリ線３１とが当接することで、両者が通電するようになっている。
【００２３】
次に、本実施の形態に係るトロリ線の摩耗模擬試験装置１１の作用を説明する。
【００２４】
図１に示した試験装置１１を用いて、通常の摩耗の模擬試験を行う場合は、先ず、第２シリンダ１６への供給圧力を制御して、ピストン部材１６ｂを伸長駆動させると共に、押し付け金具１７をレール部材１６ｃに沿ってスライドさせ、押し付け金具１７に押圧された摺動板１８をトロリ線３１に押し付けて当接させる。これによって、摺動板１８とトロリ線３１とが通電する。
【００２５】
次に、第１シリンダ１５への供給圧力を制御して、ピストン部材１５ｂを伸長駆動させると共に、第２シリンダ１６の本体部１６ａをレール部材１５ｃに沿ってスライドさせ、摺動板１８をトロリ線３１の長手方向に走行させて摩耗模擬試験を行う。ピストン部材１５ｂが最大長さに伸長して、第２シリンダ１６の本体部１６ａがレール部材１５ｃの左端に達したら、今度はピストン部材１５ｂが収縮駆動する。また、ピストン部材１５ｂが最小長さに収縮して、第２シリンダ１６の本体部１６ａがレール部材１５ｃの右端に達したら、今度はピストン部材１５ｂが伸長駆動する。
【００２６】
摩耗模擬試験中の検知線３５の特性は、検知線３５に接続された測定器２０で測定・検知される。
【００２７】
一方、試験装置１１を用いて、アーク摩耗の模擬試験を行う場合は、先ず、前述した通常摩耗の模擬試験の手順で摩耗模擬試験を開始した後、所定のタイミングで、かつ、０．１〜数秒間、第２シリンダ１６への圧力供給を停止する（又は供給を低減する）。この圧力供給の停止（又は供給の低減）のタイミングは、調節装置１９によって行う。
【００２８】
第２シリンダ１６への圧力供給の停止（又は供給の低減）によって、摺動板１８及び押し付け金具１７の自重により、摺動板１８とトロリ線３１とが離線して隙間が生じる（摺動板１８とトロリ線３１との間に離線現象が発生する）。この時、電圧差によって、摺動板１８とトロリ線３１との隙間にアーク放電が発生し、アーク摩耗の模擬試験が行われる。アーク摩耗の摩耗模擬試験中においても、検知線３５の特性は、検知線３５に接続された測定器２０で測定・検知される。
【００２９】
ここで、調節装置１９が第２シリンダ１６のみを調節する場合は、タイマ等を用いて一定間隔で第２シリンダ１６の本体部１６ａへの圧力の供給・停止（又は供給の低減）を調節する。また、調節装置１９が両シリンダ１５，１６を調節する場合は、第１シリンダ１５のピストン部材１５ｂの伸長（又は収縮）具合いに応じて、第２シリンダ１６の本体部１６ａへの圧力の供給・停止（又は供給の低減）を調節する。
【００３０】
本実施の形態の模擬試験装置１１によれば、トロリ線３１は直線状に固定・配置されており、図４に示した試験装置４１におけるトロリ線３１，４４のように回転しないことから、予め、検知線３５をトロリ線３１の端末部から必要長さだけ取り出して（延長させて）おくことで、摩耗模擬試験中に検知線３５を取り出す必要がなくなる。その結果、実際に架線されているのと略同じ状態に配置・固定されたトロリ線３１が、摩耗試験開始から摩耗限界に至るまでの検知線３５の特性の変動を、連続的に（常時）測定・検知（検証）することができる。
【００３１】
また、摩耗模擬試験中、第２シリンダ１６（又は両シリンダ１５，１６）の駆動を調節することで、トロリ線３１から摺動板１８を任意に離線させることができ、通電アーク摩耗を模擬試験することができる。また、第２シリンダ１６（又は両シリンダ１５，１６）の駆動の調節によって、隙間の大きさ又は隙間の発生時間を任意に調節することが可能となると共に、アーク放電の発生位置を任意に調節する、即ちトロリ線３１の常に同じ位置でアーク放電を発生させることも可能となる。
【００３２】
以上、本発明の実施の形態は、上述した実施の形態に限定されるものではなく、他にも種々のものが想定されることは言うまでもない。
【００３３】
【発明の効果】
以上要するに本発明によれば、通電アーク摩耗を模擬試験することができ、また、検知線入りトロリ線の摩耗による検知線特性の変化を連続的に測定・検知することができるという優れた効果を発揮する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a simulated wear test device for a trolley wire, and more particularly to a simulated wear test device for a grooved trolley wire for an electric railway.
[0002]
[Prior art]
The trolley wire has a good conductivity, a large tensile load, and is excellent in abrasion resistance. Therefore, the trolley wire is frequently used for a power supply wire of an electric railway, a wire of a crane, and the like.
[0003]
A trolley wire used for a power supply overhead line of an electric railway is a grooved trolley wire 21 having grooves 22 on both sides as shown in FIG. The trolley wire 21 slides on the pantograph when the train passes, and the trolley wire 21 is worn by repeated sliding. As the wear progresses, the strength of the trolley wire 21 may be reduced, leading to disconnection.
[0004]
For this reason, as shown in FIG. 3, insertion grooves 34a and 34b are formed at the wear limit position (wear limit line AA) of the large arc surface portion 33 of the grooved trolley wire main body (hereinafter, referred to as the trolley wire main body) 32. In addition, a trolley wire 31 including a detection line in which detection lines 35, 35 for detecting wear are inserted into the insertion grooves 34a, 34b.
[0005]
In the wear detection system using the trolley wire 31, first, the detection wires 35, 35 are exposed as the wear of the trolley wire main body 32 progresses, and then, the wear further progresses to insulate the detection wires 35, 35. The conductor is exposed by shaving the coating layer and the like, and the conductor and the trolley wire body come into contact with each other to conduct (or break), thereby performing detection. In the trolley wire 31, it is an important factor to determine the structure and the like of the trolley wire 31 by verifying the presence or absence of detection due to wear in the overhead wire and confirming the effectiveness of the wear detection system. Before doing so, a test simulating wear must be performed.
[0006]
As shown in FIG. 4, a conventional wear simulation test device 41 is configured such that a test trolley wire 44 is wound around an outer peripheral portion of a disk-shaped fixing device 42 via a mounting bracket 43, and then the fixing device 42 is fixed. While rotating at a speed, the sliding plate 45 is pressed against the trolley wire 44 to be worn, and the wear amount of the trolley wire 44 or the sliding plate 45 is measured at every constant rotation.
[0007]
[Problems to be solved by the invention]
When the trolley wire 31 shown in FIG. 3 is used in the test apparatus 41, the detection wires 35, 35 also rotate together with the trolley wire 31 during the test. It cannot be connected to an external measuring device (not shown) for measuring the change / fluctuation of. In addition, if the test is performed while energizing, wear cannot be detected due to noise caused by rotation. For these reasons, it is not possible to continuously verify the detection line characteristics due to wear, that is, the insulation characteristics or communication characteristics when the wear limit is reached. Had to be stopped. That is, in the test device 41, there is a problem that the fluctuation of the detection line characteristic due to the wear cannot be continuously measured and detected (verified).
[0008]
In addition, since the sliding plate 45 is pressed against the trolley wire 44 with a constant load using the spring 46, the current-carrying arc abrasion (pantograph graph) generated when the trolley wire is actually used as an overhead wire is used. There is a problem that it is not possible to perform a simulation test of abrasion caused by an arc generated when the sliding plate is separated from the trolley wire.
[0009]
In view of the above circumstances, an object of the present invention created in consideration of the above-described circumstances is that a simulated test of current-carrying arc abrasion can be performed, and that a trolley wire capable of continuously measuring and detecting a change in a detection line characteristic due to abrasion of a trolley wire including a detection line. To provide a wear simulation test device.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, a trolley wire wear simulation test device according to the present invention is a device for simulating a trolley wire wear condition by sliding a trolley wire and a sliding plate. A sliding plate in contact with the wire, first reciprocating means for reciprocating the sliding plate in a longitudinal direction of the trolley wire, and a sliding plate provided to connect the sliding plate to separate the sliding plate from the trolley wire A second reciprocating means for reciprocatingly moving in contact.
[0011]
Further, an adjusting means for adjusting the reciprocating movement timing may be connected to at least the second reciprocating means among the reciprocating means.
[0012]
Further, the trolley wire may be a trolley wire including a detection wire.
[0013]
According to the configuration described above, a simulation test of energized arc wear can be performed, and a change in detection line characteristics due to wear of the trolley wire including the detection line can be continuously measured and detected.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.
[0015]
FIG. 1 is a schematic view of a trolley wire wear simulation test apparatus according to the first embodiment. Note that the same members as those in FIGS. 2 and 3 are denoted by the same reference numerals.
[0016]
As shown in FIG. 1, a trolley wire wear simulation test apparatus 11 according to the present embodiment includes a trolley wire 31 linearly arranged and fixed to a ceiling 12 or the like via a mounting bracket 13, and a trolley wire 31. , A pressing member (pressing means) 17 for pressing the sliding plate 18 against the trolley wire 31 at a constant pressure, and a sliding plate 18 and a pressing member fixedly provided on the floor surface 14 or the like. A first cylinder (first reciprocating means) 15 for reciprocating the trolley wire 17 in the longitudinal direction of the trolley wire 31 and a press fitting 17 are provided to connect the sliding plate 18 to the trolley wire 31. And a second cylinder (second reciprocating means) 16 for reciprocating freely.
[0017]
The detection wires 35, 35 are inserted into the grooves 34a, 34b of the trolley wire 31 (see FIG. 3). The detection wires 35, 35 are formed by folding one detection wire of a predetermined length in a loop shape. The two terminals of the detection line are connected to a measuring device 20 that constantly observes and measures the characteristics of the detection line.
[0018]
The pressing fitting 17 has a pressing member (not shown) such as a spring. The pressing member always presses the sliding plate 18 against the trolley wire 31 at a constant pressure, so that the sliding plate 18 is slid. At this time, the sliding plate 18 and the trolley wire 31 surely come into contact with each other.
[0019]
The first cylinder 15 and the second cylinder 16 are composed of main bodies 15a, 16a, piston members 15b, 16b, and rail members 15c, 16c, respectively. The piston member 15b of the first cylinder 15 is connected to the main body 16a of the second cylinder 16, and the main body 16a of the second cylinder 16 is connected to the rail member 15c of the first cylinder 15 as the piston member 15b expands and contracts. Slide along. The piston member 16b of the second cylinder 16 is connected to the pressing member 17, and the pressing member 17 slides along the rail member 16c of the second cylinder 16 as the piston member 16b expands and contracts. Further, the rail member 15c is arranged along the longitudinal direction of the trolley wire 31 (the horizontal direction in FIG. 1), and the rail member 16c is arranged in a direction perpendicular to the longitudinal direction of the trolley wire 31 (vertical direction in FIG. 1). It is arranged along. Here, each of the cylinders 15 and 16 may be either pneumatic control or hydraulic control. Further, in the present embodiment, the case where the first and second cylinders 15 and 16 are used as the first and second reciprocating means has been described, but the sliding plate 18 is moved in the longitudinal direction of the trolley wire 31. Also, there is no particular limitation as long as it can reciprocate freely with respect to and away from the trolley wire 31.
[0020]
The reciprocating distance of the first cylinder 15 and the second cylinder 16 is adjusted by a position sensor (not shown) such as an electro-optical non-contact sensor. The reciprocating speed of each of the cylinders 15 and 16 is adjusted by air (or oil). Adjust by the supply pressure or the speed control valve.
[0021]
An adjusting device (adjusting means) 19 for adjusting the drive timing of each of the cylinder main bodies 15a, 16a of each of the cylinders 15, 16 is connected via lines 19a, 19b. The adjusting device 19 is not particularly limited as long as the driving timing of each of the cylinders 15 and 16 can be adjusted. Further, in the present embodiment, the case where the adjusting device 19 adjusts the drive timing of the two cylinders 15 and 16 has been described, but the adjuster 19 adjusts only the drive timing of the second cylinder 16. Is also good.
[0022]
The sliding plate 18 is connected to the power supply 10 via a power supply line 10a, and the trolley wire 31 is connected to the power supply 10 via a power supply line 10b. By contact, both are energized.
[0023]
Next, the operation of the trolley wire wear simulation test apparatus 11 according to the present embodiment will be described.
[0024]
When performing a normal wear simulation test using the test apparatus 11 shown in FIG. 1, first, the supply pressure to the second cylinder 16 is controlled to drive the piston member 16 b to extend and to push the pressing member 17. Is slid along the rail member 16c, and the sliding plate 18 pressed by the pressing fitting 17 is pressed against the trolley wire 31 to make contact therewith. Thus, the sliding plate 18 and the trolley wire 31 are energized.
[0025]
Next, the supply pressure to the first cylinder 15 is controlled to drive the piston member 15b to extend, and at the same time, the main body 16a of the second cylinder 16 is slid along the rail member 15c, so that the sliding plate 18 is connected to the trolley wire. 31 is run in the longitudinal direction to perform a wear simulation test. When the piston member 15b extends to the maximum length and the main body 16a of the second cylinder 16 reaches the left end of the rail member 15c, the piston member 15b is driven to contract this time. When the piston member 15b contracts to the minimum length and the main body 16a of the second cylinder 16 reaches the right end of the rail member 15c, the piston member 15b is driven to extend this time.
[0026]
The characteristics of the detection line 35 during the wear simulation test are measured and detected by the measuring device 20 connected to the detection line 35.
[0027]
On the other hand, when performing a simulation test of arc wear using the test apparatus 11, first, a wear simulation test is started in the procedure of the above-described normal wear simulation test, and then at a predetermined timing and 0.1 to The supply of pressure to the second cylinder 16 is stopped for a few seconds (or the supply is reduced). The timing of stopping the pressure supply (or reducing the supply) is performed by the adjusting device 19.
[0028]
When the supply of pressure to the second cylinder 16 is stopped (or the supply is reduced), the sliding plate 18 and the trolley wire 31 are separated from each other due to the own weight of the sliding plate 18 and the press fitting 17, and a gap is generated (sliding plate). A disconnection phenomenon occurs between the trolley wire 18 and the trolley wire 31). At this time, an arc discharge occurs in a gap between the sliding plate 18 and the trolley wire 31 due to the voltage difference, and a simulation test of arc wear is performed. Even during a wear simulation test of arc wear, the characteristics of the detection line 35 are measured and detected by the measuring device 20 connected to the detection line 35.

Here, when the adjusting device 19 adjusts only the second cylinder 16, the supply / stop (or reduction of supply) of the pressure to the main body 16 a of the second cylinder 16 is adjusted at regular intervals using a timer or the like. . When the adjusting device 19 adjusts both the cylinders 15 and 16, the supply and supply of pressure to the main body 16 a of the second cylinder 16 are performed according to the degree of extension (or contraction) of the piston member 15 b of the first cylinder 15. Adjust outages (or feed reductions).

According to the simulation test apparatus 11 of the present embodiment, the trolley wire 31 is fixed and arranged in a straight line and does not rotate like the trolley wires 31 and 44 in the test apparatus 41 shown in FIG. By taking out (extending) the required length of the detection wire 35 from the end of the trolley wire 31, it is not necessary to take out the detection wire 35 during the wear simulation test. As a result, the trolley wire 31 arranged and fixed in substantially the same state as that actually wired is used to continuously (always) change the characteristics of the detection wire 35 from the start of the wear test to the wear limit. It can be measured and detected (verified).
[0031]
Further, during the wear simulation test, the slide plate 18 can be arbitrarily separated from the trolley wire 31 by adjusting the drive of the second cylinder 16 (or both cylinders 15 and 16), and the simulation test of the energized arc wear is performed. can do. Further, by adjusting the driving of the second cylinder 16 (or both the cylinders 15 and 16), the size of the gap or the time of occurrence of the gap can be arbitrarily adjusted, and the position of the arc discharge can be arbitrarily adjusted. That is, it is also possible to generate an arc discharge at the same position of the trolley wire 31 at all times.
