Description

この発明は、パンタグラフすり板の磨耗検知装置に関するものである。   The present invention relates to a wear detector for pantograph slip plates.

電車では、一般的に、架線から電力を集電するために、パンタグラフを用いている。図２（ａ），（ｂ）は従来の例えば新幹線用シングルアーム式のパンタグラフの正面図及びその要部拡大側断面図であり、パンタグラフ１は電車の車両２の屋根に伸縮自在に取り付けられている。即ち、車両２側に位置固定された主軸３に下枠４の一端が連結され、下枠４の他端にはヒンジ部５を介して上枠６の一端が連結され、上枠６の他端には舟体支持部７が支持され、舟体支持部７にはそり板状の舟体８が上下動可能に支持され、舟体８の上部には架線９と摺接して受電するすり板１０が設けられている。架線９はハンガー等により支持され、振れ止め具等により固定されている。   In trains, pantographs are generally used to collect power from overhead lines. 2 (a) and 2 (b) are a front view of a conventional single-arm pantograph for Shinkansen, for example, and an enlarged side cross-sectional view thereof. The pantograph 1 is attached to the roof of a train vehicle 2 so as to be stretchable. Yes. That is, one end of the lower frame 4 is connected to the main shaft 3 fixed to the vehicle 2 side, and one end of the upper frame 6 is connected to the other end of the lower frame 4 via the hinge portion 5. A boat body support portion 7 is supported at the end, a sled plate-like boat body 8 is supported on the boat body support portion 7 so as to be movable up and down, and the upper portion of the boat body 8 is slidably contacted with the overhead wire 9 to receive power. A plate 10 is provided. The overhead wire 9 is supported by a hanger or the like and fixed by a steady rest or the like.

１１はパンタグラフ１を上昇させるための主ばねであり、その一端は車両２側に固定され、他端は主軸３側に連結されている。１２は一端が車両２側に固定され、パンタグラフ１の形状を保つために設けられた釣合棒であり、釣合棒１２の他端は上枠６のヒンジ部５側端部から一体に突出した突出部１３に連結される。１４は一端が舟体支持部７に連結され、舟体８を水平に保つために設けられた平衡棒であり、その他端はヒンジ部５に連結される。   11 is a main spring for raising the pantograph 1, one end of which is fixed to the vehicle 2 side, and the other end is connected to the main shaft 3 side. Reference numeral 12 denotes a balancing rod which is fixed to the vehicle 2 side and is provided to keep the shape of the pantograph 1. The other end of the balancing rod 12 projects integrally from the hinge 5 side end of the upper frame 6. Connected to the protruding portion 13. Reference numeral 14 denotes a balance rod having one end connected to the hull support 7 and keeping the hull 8 horizontal, and the other end connected to the hinge 5.

パンタグラフ１のすり板１０は、架線９との接触により電力を集電しているため、車両２の走行と共に摩擦により徐々に擦り減ってくる。このすり板１０の減り具合により、すり板１０の交換が行われるが、現在では車両基地等の出入り口でパンタグラフ１のすり板１０の監視を行い、異常がある場合や減り方が多い場合には取り替えている。又、すり板１０が破損した場合には、架線９を破壊してしまう等の重大事故に繋がることから、新幹線等では減り具合に拘わらず、定期的に取替えを行っている。   Since the sliding plate 10 of the pantograph 1 collects electric power by contact with the overhead wire 9, it gradually wears away due to friction as the vehicle 2 travels. The sliding plate 10 is replaced due to the reduction of the sliding plate 10, but at present, the sliding plate 10 of the pantograph 1 is monitored at the entrance and exit of the vehicle base or the like, and when there is an abnormality or there are many ways to reduce the sliding plate 10 It has been replaced. Further, if the sliding plate 10 is damaged, it will lead to a serious accident such as destroying the overhead wire 9, so the Shinkansen or the like is periodically replaced regardless of the reduction.

ところで、車両基地の出入り口における監視はオンラインの監視ではないために、車両走行中のすり板の磨耗監視ができず、一度車両基地から出てしまうと、車両基地に戻るまではすり板の磨耗を監視することができない。従って、車両編成によっては、長い区間走行したり、数往復任意の区間を走行するなど、車両編成ごとに車両基地に戻るまでの走行距離にバラツキがあるため、適切な管理ができなかった。又、車両基地の出入り口の監視では、事故があった場合の原因追究には役に立たなかった。さらに、新幹線等では磨耗の進み具合とは関係なしに定期的にすり板の交換を行っており、費用負担と無駄が大きかった。   By the way, since monitoring at the entrance and exit of the vehicle base is not online monitoring, it is not possible to monitor the wear of the sliding plate while the vehicle is running, and once it leaves the vehicle base, the wear of the sliding plate is not repeated until it returns to the vehicle base. It cannot be monitored. Therefore, depending on the vehicle formation, the travel distance until returning to the vehicle base varies for each vehicle formation, such as traveling in a long section or traveling in an arbitrary section of several round trips. In addition, monitoring the doorway of the vehicle base did not help to investigate the cause of the accident. Furthermore, on the Shinkansen and the like, the sliding plates are regularly replaced regardless of the progress of wear, and the cost burden and waste are large.

又、本出願人が既に提案したパンタグラフすり板の磨耗検知装置おいては、すり板に光ケーブルを埋設し、この光ケーブルがすり板の磨耗により断線することによりすり板の磨耗を検知していたが、この光ケーブルをパンタグラフの上枠、下枠を介して光信号の送受信部まで配設する必要があり、パンタグラフの構造が複雑になり、高価になるという課題があった。   In addition, in the pantograph sliding plate wear detection device already proposed by the present applicant, an optical cable is embedded in the sliding plate, and this optical cable detects the wear of the sliding plate by disconnection due to the wear of the sliding plate. This optical cable needs to be arranged up to the optical signal transmission / reception unit through the upper and lower frames of the pantograph, and there is a problem that the structure of the pantograph becomes complicated and expensive.

この発明は上記のような課題を解決するために成されたものであり、すり板の磨耗の位置や程度を検知することができるとともに、事故原因の追究が可能であり、かつ光ケーブルが不要で安価にすることができるパンタグラフすり板の磨耗検知装置を得ることを目的とする。   The present invention has been made to solve the above-described problems, and can detect the position and degree of wear of the sliding plate, can investigate the cause of the accident, and does not require an optical cable. An object of the present invention is to obtain a pantograph slip plate wear detection device that can be made inexpensive.

この発明の請求項１に係るパンタグラフすり板の磨耗検知装置は、車両の屋根に取り付けられたパンタグラフの上部に設けられ、架線と摺接して受電するパンタグラフすり板において、該すり板の異なる位置に設けられ、それぞれ異なる信号を無線で発信する複数の無線ＩＣタグと、無線ＩＣタグからの無線情報を受信する受信部とを備え、無線ＩＣタグがすり板の磨耗により外れて受信不能となったことにより、その受信不能となった無線ＩＣタグの取付位置からすり板の磨耗の位置と程度を検知するようにしたものである。   According to a first aspect of the present invention, there is provided a pantograph sliding plate wear detecting device provided on an upper part of a pantograph attached to a roof of a vehicle and receiving power by sliding contact with an overhead wire at a different position of the sliding plate. Provided with a plurality of wireless IC tags for wirelessly transmitting different signals, and a receiving unit for receiving wireless information from the wireless IC tag, the wireless IC tag is detached due to wear of the sliding plate and cannot be received. Thus, the position and degree of wear of the sliding plate are detected from the mounting position of the wireless IC tag that has become unreceivable.

以上のようにこの発明の請求項１によれば、すり板の異なる位置に複数の無線ＩＣタグが設けられ、各無線ＩＣタグは異なる信号を無線で発信している。すり板の磨耗により無線ＩＣタグが外れると、その無線ＩＣタグからの無線情報を受信部は受信できなくなり、その受信できなくなった無線ＩＣタグの取付位置からすり板のどの位置がどの程度磨耗したかを検知することができる。又、運転状況に異常が生じた場合に、異常原因がパンタグラフのすり板の磨耗であるのか、あるいは架線の異常によるのか等の異常原因を追究することができる。さらに、光ケーブルを用いないので、その配設も必要でなく、パンタグラフの構造も簡単になり、安価にすることができる。   As described above, according to the first aspect of the present invention, a plurality of wireless IC tags are provided at different positions on the sliding plate, and each wireless IC tag transmits a different signal wirelessly. When the wireless IC tag is detached due to wear of the sliding plate, the receiving unit cannot receive wireless information from the wireless IC tag, and how much of the position of the sliding plate is worn away from the mounting position of the wireless IC tag that cannot be received. Can be detected. Further, when an abnormality occurs in the operation status, it is possible to investigate the cause of the abnormality such as whether the cause of the abnormality is wear of a pantograph sliding plate or an error in the overhead wire. Furthermore, since no optical cable is used, the arrangement thereof is not necessary, and the structure of the pantograph is simplified and can be made inexpensive.

以下、この発明を実施するための最良の形態を図面とともに説明する。図１（ａ），（ｂ）はこの発明の実施最良形態によるパンタグラフすり板の磨耗検知装置の正面図及び要部拡大側断面図であり、パンタグラフ１は車両２の屋根に伸縮自在に取り付けられている。即ち、車両２側に位置固定された主軸３に下枠４の一端が連結され、下枠４の他端にはヒンジ部５を介して上枠６の一端が連結され、上枠６の他端には舟体支持部７が支持され、舟体支持部７にはそり板状の舟体８が上下動可能に支持され、舟体８の上部には架線９と摺接して受電するすり板１０が設けられている。すり板１０には、その異なる位置に複数の無線ＩＣタグ１５が設けられ、例えば各無線ＩＣタグ１５は図１（ｂ）のＡ−Ｂに示すように左右方向に設けられ、あるいは図１（ｂ）のＣ−Ｄに示すように高さ方向を異ならせて設けられる。又、各無線ＩＣタグ１５は例えば周波数や長さ等の異なる信号を無線で発信する。又、車両２の屋根上には無線ＩＣタグ１５から無線で発信された信号を受信する受信部１６が取り付けられる。   The best mode for carrying out the present invention will be described below with reference to the drawings. FIGS. 1A and 1B are a front view and an enlarged side sectional view of a pantograph sliding plate wear detecting device according to the best mode of the present invention. The pantograph 1 is attached to a roof of a vehicle 2 so as to be stretchable. ing. That is, one end of the lower frame 4 is connected to the main shaft 3 fixed to the vehicle 2 side, and one end of the upper frame 6 is connected to the other end of the lower frame 4 via the hinge portion 5. A boat body support portion 7 is supported at the end, a sled plate-like boat body 8 is supported on the boat body support portion 7 so as to be movable up and down, and the upper portion of the boat body 8 is slidably contacted with the overhead wire 9 to receive power. A plate 10 is provided. A plurality of wireless IC tags 15 are provided at different positions on the sliding plate 10. For example, each wireless IC tag 15 is provided in the left-right direction as indicated by AB in FIG. As shown in CD of b), they are provided with different height directions. Each wireless IC tag 15 wirelessly transmits signals having different frequencies and lengths, for example. On the roof of the vehicle 2, a receiving unit 16 that receives a signal transmitted wirelessly from the wireless IC tag 15 is attached.

次に、上記構成の動作を説明する。各無線ＩＣタグ１５から発信された無線情報は受信部１６により受信され、車両２内の運転状況確認モニターに表示される。ここで、すり板１０が架線９との摩擦によりある部分まで擦り減ると、その位置に設けられた無線ＩＣタグ１５は外れてしまい、受信部１６はこの無線ＩＣタグ１５からの無線情報を受信できなくなる。この受信できなくなった無線ＩＣタグ１５のすり板における取付位置は受信できなくなった信号により検知することができ、この取付位置によりすり板１０のどの部分がどの程度磨耗したかを検知することができる。   Next, the operation of the above configuration will be described. The wireless information transmitted from each wireless IC tag 15 is received by the receiving unit 16 and displayed on the driving status confirmation monitor in the vehicle 2. Here, when the sliding plate 10 is worn down to a certain part due to friction with the overhead wire 9, the wireless IC tag 15 provided at that position is detached, and the receiving unit 16 receives wireless information from the wireless IC tag 15. become unable. The mounting position of the wireless IC tag 15 that can no longer be received can be detected by a signal that can no longer be received, and it can be detected how much of the portion of the sliding board 10 is worn by this mounting position. .

上記した実施最良形態においては、すり板１０の磨耗により無線ＩＣタグ１５が外れたことにより受信部１６で受信できなくなった無線情報から、外れた無線ＩＣタグ１５の取付位置を検知することができ、この取付位置からすり板１０の磨耗の位置と磨耗の程度を検知することができる。又、運転状況確認モニターの表示から異常を検知した場合に、パンタグラフ１のすり板１０の磨耗による異常であるのか、あるいは架線９の異常によりパンタグラフ１が破損したのか等の異常原因の追究が可能となる。さらに、光ケーブルを用いないので、その配設も必要でなく、パンタグラフ１の構造も簡単になり、安価にすることができる。   In the above-described best embodiment, the mounting position of the detached wireless IC tag 15 can be detected from wireless information that cannot be received by the receiving unit 16 because the wireless IC tag 15 has been detached due to wear of the sliding plate 10. The position and degree of wear of the sliding plate 10 can be detected from the mounting position. In addition, when an abnormality is detected from the display of the operation status confirmation monitor, it is possible to investigate the cause of the abnormality, such as whether the pantograph 1 is damaged due to wear of the sliding plate 10 of the pantograph 1 or the overhead line 9 is damaged. It becomes. Further, since no optical cable is used, the arrangement thereof is not necessary, and the structure of the pantograph 1 is simplified and can be made inexpensive.

なお、本発明では、図１の形状のパンタグラフにて説明したが、他の形状のパンタグラフでも同様の効果を奏するのは勿論のことである。   In the present invention, the pantograph having the shape shown in FIG. 1 has been described, but it is needless to say that the same effect can be obtained with other shapes of pantographs.

この発明の実施最良形態によるパンタグラフすり板の磨耗検知装置の正面図及びその要部拡大側断面図である。BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view of an apparatus for detecting wear of a pantograph sliding plate according to an embodiment of the present invention and an enlarged side sectional view thereof. 従来のパンタグラフの正面図及びその要部拡大側断面図である。It is the front view of the conventional pantograph, and its principal part expanded sectional side view.
