Description

本発明は、配線ダクトに関するものである。   The present invention relates to a wiring duct.

従来から、寒冷地における列車のレールには電気融雪器が設置されている。この電気融雪器の配線は、線路に沿って配線ダクトが設けられ、その配線ダクト内に敷設されている。従来の配線ダクト１１０は、図５、図６に示すように、断面略Ｃ字状の配線ダクト本体１１１内にケーブル（不図示）を収容し、所定間隔ごとに脱落防止金具１１５を配線ダクトの開口部１１２に取り付けている。このような配線ダクトの開口部を塞ぐカバーとしては、特許文献１のようなものも提案されている。   Conventionally, electric snow melters have been installed on train rails in cold regions. The wiring of this electric snowmelter is provided with a wiring duct along the track, and is laid in the wiring duct. As shown in FIGS. 5 and 6, the conventional wiring duct 110 accommodates a cable (not shown) in a wiring duct body 111 having a substantially C-shaped cross section, and attaches the drop-off prevention metal fitting 115 to the wiring duct at predetermined intervals. It is attached to the opening 112. As a cover for closing the opening of such a wiring duct, a cover as in Patent Document 1 has been proposed.

特開平９−１７２７１７号公報JP-A-9-172717

ところで、特許文献１のようなカバーは、配線ダクトの開口部を覆うとともに開口部の両側に形成された壁部の外側に覆うように構成されている。このような構成のカバーでは砕石上に配される配線ダクトに取り付けるには砕石を避けて取り付ける必要があり、カバーの取り付けに手間がかかるという問題がある。   By the way, a cover like patent document 1 is comprised so that it may cover the outer side of the wall part formed in the both sides of an opening part while covering the opening part of a wiring duct. In the cover having such a configuration, it is necessary to avoid the crushed stone to be attached to the wiring duct arranged on the crushed stone, and there is a problem that it takes time to install the cover.

また、特許文献１のカバーや図７に示す従来の金具１１５では、列車の振動などにより配線ダクト本体１１１から脱落する虞がある。配線ダクトからケーブルが脱落して露出すると、ケーブルの絶縁低下を招く虞がある。さらに、脱落した金具１１５は、点検の際に復旧させる必要があり、作業に手間がかかるという問題がある。   Moreover, in the cover of patent document 1, and the conventional metal fitting 115 shown in FIG. 7, there exists a possibility of dropping from the wiring duct main body 111 by the vibration of a train, etc. If the cable falls off the wiring duct and is exposed, the insulation of the cable may be reduced. Further, the dropped metal fitting 115 needs to be restored at the time of inspection, and there is a problem that work is troublesome.

そこで、本発明は、上述の事情を鑑みてなされたものであり、ケーブルを確実に収容することが可能な配線ダクトを提供するものである。   Therefore, the present invention has been made in view of the above-described circumstances, and provides a wiring duct that can reliably accommodate a cable.

上記の課題を解決するために、請求項１に記載した発明は、列車のレールに沿って配され該レールに設けられる電気融雪器の配線を収容可能な配線ダクト本体と、該配線ダクト本体に長手方向に沿って形成された開口部を部分的に閉塞して前記配線が脱落するのを防止する脱落防止金具と、を備えた配線ダクトにおいて、前記脱落防止金具は、前記開口部の端部を付勢力を持って挟持可能に構成され、前記開口部のうち前記脱落防止金具に閉塞されていない部分を通して前記配線ダクト本体の内部に前記配線を出し入れ可能に構成されていて、前記配線ダクト本体は、長手方向に沿って形成された側壁部と、該側壁部の上端および下端からそれぞれ側方へ延設された上板部および下板部と、前記上板部から下方へ折り返された上側折返し部と、前記下板部から上方へ折り返された下側折返し部と、を有し、前記上側折返し部と前記下側折返し部との間が前記開口部として形成され、内部が前記配線の収容部として構成されており、前記脱落防止金具は、前記側壁部に当接される側壁押さえ部と、該側壁押さえ部に連接され前記上板部を架け渡すように形成された水平板部と、該水平板部に連接され前記上側折返し部、前記開口部および前記下側折返し部を架け渡すように形成された垂直板部と、該垂直板部における前記収容部に面した内側面に配され、前記垂直板部に向かって付勢力を有する付勢板部と、を備え、前記垂直板部と前記付勢板部との間に前記下側折返し部が挟持されることを特徴としている。 In order to solve the above-described problems, the invention described in claim 1 includes a wiring duct body that is arranged along a rail of a train and can accommodate the wiring of an electric snowmelter provided on the rail, and the wiring duct body . A drop-off prevention fitting that partially closes an opening formed along the longitudinal direction to prevent the wiring from falling off, wherein the drop-off prevention fitting is an end portion of the opening. The wiring duct is configured such that the wiring can be inserted into and removed from the inside of the wiring duct body through a portion of the opening that is not blocked by the drop-off prevention metal fitting. The main body is folded back downward from the side plate formed along the longitudinal direction, the upper plate and the lower plate extending from the upper and lower ends of the side wall to the side, respectively. With the upper folding part A lower folded portion folded upward from the lower plate portion, and a portion between the upper folded portion and the lower folded portion is formed as the opening, and the inside is configured as a housing portion for the wiring The drop-off prevention metal fitting includes: a side wall pressing portion that is in contact with the side wall portion; a horizontal plate portion that is connected to the side wall pressing portion and that spans the upper plate portion; and the horizontal plate A vertical plate portion connected to the upper portion and formed so as to bridge the upper folded portion, the opening and the lower folded portion, and an inner surface facing the accommodating portion in the vertical plate portion, And an urging plate portion having an urging force toward the plate portion, wherein the lower folded portion is sandwiched between the vertical plate portion and the urging plate portion .

請求項２に記載した発明は、前記側壁押さえ部に、前記側壁部に向かって付勢力を有する付勢部が形成されていることを特徴としている。 The invention described in claim 2 is characterized in that a biasing portion having a biasing force toward the side wall portion is formed in the side wall pressing portion.

請求項１に記載した発明によれば、配線ダクト本体の開口部の端部に取り付ける脱落防止金具に付勢力を持たせ、付勢しながら開口部の端部を挟持できるようにすることにより、脱落防止金具を配線ダクト本体に強固に取り付けることができる。したがって、配線ダクトに振動などが生じても脱落防止金具は配線ダクト本体から脱落することがなくなり、配線を確実に収容することができる。   According to the invention described in claim 1, by applying a biasing force to the drop-off prevention fitting attached to the end of the opening of the wiring duct main body, and allowing the end of the opening to be clamped while being biased, The drop-off prevention fitting can be firmly attached to the wiring duct body. Therefore, even if vibration or the like occurs in the wiring duct, the drop-off prevention metal fitting does not fall off from the wiring duct body, and the wiring can be reliably accommodated.

また、配線ダクト本体に取り付ける配線の脱落防止金具に付勢力を有する付勢板部を形成し、配線ダクト本体の一部である下側折返し部を付勢板部と垂直板部との間で付勢しながら挟持するようにするため、脱落防止金具は配線ダクト本体に強固に取り付けられる。したがって、配線ダクトに振動などが生じても脱落防止金具は配線ダクト本体から脱落することがなくなり、配線を確実に収容することができる。
また、振動が多く生じる列車のレールの近傍に配線ダクトを設置しても脱落防止金具が配線ダクト本体から脱落するのを防止することができる。また、列車のレール下方には砕石が敷き詰められていることが多いが、脱落防止金具を配線ダクト本体に取り付ける際に、脱落防止金具が砕石と干渉することなく取り付けることができる。したがって、脱落防止金具を容易に、かつ確実に配線ダクト本体に取り付けることができる。つまり、レールに設けられる電気融雪器用の配線を確実に収容することが可能となる。 In addition, an urging plate portion having a urging force is formed on the wiring drop prevention metal fitting to be attached to the wiring duct main body, and the lower folded portion which is a part of the wiring duct main body is disposed between the urging plate portion and the vertical plate portion. In order to hold it while energizing, the drop-off prevention metal fitting is firmly attached to the wiring duct body. Therefore, even if vibration or the like occurs in the wiring duct, the drop-off prevention metal fitting does not fall off from the wiring duct body, and the wiring can be reliably accommodated.
Moreover, even if a wiring duct is installed in the vicinity of a rail of a train where vibrations frequently occur, it is possible to prevent the drop-off prevention fitting from falling off the wiring duct body. In addition, crushed stone is often laid under the rail of the train, but when the drop-off prevention fitting is attached to the wiring duct body, the drop-off prevention fitting can be attached without interfering with the crushed stone. Therefore, the drop-off prevention metal fitting can be easily and reliably attached to the wiring duct body. That is, it is possible to reliably accommodate the wiring for the electric snow melter provided on the rail.

請求項２に記載した発明によれば、側壁押さえ部に付勢部を形成することにより、より強固に脱落防止金具を配線ダクト本体に取り付けることができる。また、付勢部を形成することにより、多少の寸法誤差が生じても吸収することができ、確実に脱落防止金具を配線ダクト本体に取り付けることができる。 According to the second aspect of the present invention, the drop-off prevention metal fitting can be more firmly attached to the wiring duct body by forming the urging portion in the side wall pressing portion. Further, by forming the urging portion, even if some dimensional error occurs, it can be absorbed and the drop-off preventing metal fitting can be securely attached to the wiring duct body.

図１に示すように、配線ダクト１０は、長尺に形成された断面略Ｃ字状の配線ダクト本体１１と、配線ダクト本体１１の長手方向に沿って形成された開口部１２を部分的に閉塞し、配線ダクト本体１１内の収容部１３に収容される配線が脱落するのを防止するために取り付けられる脱落防止金具１５と、を備えている。 Next, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a perspective view of a wiring duct.
As shown in FIG. 1, the wiring duct 10 partially includes a wiring duct main body 11 having a substantially C-shaped cross section formed in a long shape and an opening 12 formed along the longitudinal direction of the wiring duct main body 11. And a drop-off prevention metal fitting 15 which is attached to prevent the wiring housed in the housing portion 13 in the wiring duct body 11 from dropping off.

図２に示すように、配線ダクト本体１１は、例えばステンレスで形成されており、長手方向に延設された側壁部２１と、側壁部２１の上端から略水平方向へ延設された上板部２２と、側壁部２１の下端から略水平方向へ延設された下板部２３と、上板部２２における側壁部２１と連接される側の反対側の端部から下方へ折り返された上側折返し部２４と、下板部２３における側壁部２１と連接される側の反対側の端部から上方へ折り返された下側折返し部２５と、を有している。また、上側折返し部２４と下側折返し部２５との間が開口部１２として形成され、その内部は配線が収容可能な収容部１３として構成されている。   As shown in FIG. 2, the wiring duct body 11 is made of, for example, stainless steel, and includes a side wall portion 21 extending in the longitudinal direction and an upper plate portion extending in a substantially horizontal direction from the upper end of the side wall portion 21. 22, a lower plate portion 23 extending in a substantially horizontal direction from the lower end of the side wall portion 21, and an upper turn folded downward from an end portion of the upper plate portion 22 opposite to the side connected to the side wall portion 21. And a lower folded portion 25 that is folded upward from an end of the lower plate portion 23 opposite to the side connected to the side wall portion 21. Further, an opening 12 is formed between the upper folded portion 24 and the lower folded portion 25, and the inside is configured as a housing portion 13 that can accommodate wiring.

図３に示すように、脱落防止金具１５は、例えばステンレスで形成された断面略Ｌ字状の部材であり、側壁部２１の外側面２１ａに当接される側壁押さえ部３１と、側壁押さえ部３１に連接され上板部２２を架け渡すように形成された水平板部３２と、水平板部３２に連接され上側折返し部２４、開口部１２および下側折返し部２５を架け渡すように形成された垂直板部３３と、垂直板部３３における収容部１３に面した内側面３３ａに配され、垂直板部３３に向かって付勢力を有する付勢板部３４と、を備えている。なお、垂直板部３３と付勢板部３４とは、略同一の幅で形成されている。   As shown in FIG. 3, the drop-off prevention metal fitting 15 is a member having a substantially L-shaped cross section formed of, for example, stainless steel, a side wall pressing portion 31 that is in contact with the outer surface 21 a of the side wall portion 21, and a side wall pressing portion. A horizontal plate portion 32 connected to 31 and formed to bridge the upper plate portion 22, and connected to the horizontal plate portion 32 and formed to bridge the upper folded portion 24, the opening portion 12 and the lower folded portion 25. A vertical plate portion 33, and an urging plate portion 34 that is disposed on an inner surface 33 a of the vertical plate portion 33 facing the accommodating portion 13 and has a urging force toward the vertical plate portion 33. The vertical plate portion 33 and the biasing plate portion 34 are formed with substantially the same width.

付勢板部３４は、垂直板部３３に当接して例えば溶接接合された当接部３６と、当接部３６に連接され垂直板部３３から離間する方向に延設されたクランク部３７と、クランク部３７に連接され垂直板部３３と略平行に配された挟持片部３８と、を備えている。そして、垂直板部３３と狭持片部３８との間に形成された空間Ｄに配線ダクト本体１１の下側折返し部２５が嵌合されて支持固定されるように構成されている。   The urging plate portion 34 is in contact with the vertical plate portion 33 to be welded, for example, and a crank portion 37 that is connected to the contact portion 36 and extends in a direction away from the vertical plate portion 33. , And a clamping piece portion 38 connected to the crank portion 37 and arranged substantially parallel to the vertical plate portion 33. The lower folded portion 25 of the wiring duct main body 11 is fitted and supported and fixed in a space D formed between the vertical plate portion 33 and the holding piece portion 38.

また、脱落防止金具１５の側壁押さえ部３１は、幅方向に沿って付勢部３５が形成されている。具体的には、側壁押さえ部３１の幅方向に沿って凹陥部が形成され、該凹陥部が付勢部３５として構成されている。また、側壁押さえ部３１の下端部３１ａは、脱落防止金具１５を配線ダクト本体１１に取り付けた際に、側壁部２２の外側面２１ａから所定距離離間するように構成されている。このようにすることで、メンテナンスなどで脱落防止金具１５を配線ダクト本体１１から取り外す際に、下端部３１ａに手を掛けることができ、容易に脱落防止金具１５を取り外すことができる。   Further, the side wall pressing portion 31 of the drop-off prevention metal fitting 15 is formed with a biasing portion 35 along the width direction. Specifically, a recessed portion is formed along the width direction of the side wall pressing portion 31, and the recessed portion is configured as an urging portion 35. Further, the lower end portion 31 a of the side wall pressing portion 31 is configured to be separated from the outer surface 21 a of the side wall portion 22 by a predetermined distance when the drop-off prevention metal fitting 15 is attached to the wiring duct body 11. By doing in this way, when removing the drop-off prevention metal fitting 15 from the wiring duct main body 11 by maintenance etc., a hand can be put on the lower end part 31a and the drop-off prevention metal fitting 15 can be removed easily.

図４は配線ダクトを列車のレールに沿って配置し、レールに設けられる電気融雪器の配線を配線ダクトに収容した状態を示す図である。
図４に示すように、特に寒冷地などでは列車のレール５０に電気融雪器（不図示）を設けている。そして、電気融雪器に電源を供給するための配線５１が配線ダクト１０に収容されている。ここで、配線ダクト１０はレール５０に沿って配設されるとともに、砕石５３上に配設されている。また、配線ダクト１０の開口部１２がレール５０の方向を向くように配置されている。 FIG. 4 is a diagram showing a state in which the wiring duct is arranged along the rail of the train and the wiring of the electric snow melting device provided on the rail is accommodated in the wiring duct.
As shown in FIG. 4, an electric snow melter (not shown) is provided on the rail 50 of the train, particularly in cold regions. A wiring 51 for supplying power to the electric snow melter is accommodated in the wiring duct 10. Here, the wiring duct 10 is disposed along the rail 50 and is disposed on the crushed stone 53. Further, the opening 12 of the wiring duct 10 is arranged so as to face the direction of the rail 50.

なお、レール５０側から延設されている配線５１は、配線ダクト１０の収容部１３内に収容されるまでは配線５１を保護するために保護菅５４に収容されている。保護菅５４は、例えば樹脂製のフレキシブル配管を用いている。   In addition, the wiring 51 extended from the rail 50 side is accommodated in the protective rod 54 in order to protect the wiring 51 until it is accommodated in the accommodating part 13 of the wiring duct 10. FIG. For example, a resin-made flexible pipe is used for the protective rod 54.

さらに、配線５１が収容された状態で、開口部１２を部分的に閉塞して配線５１が収容部１３内から露出しないように脱落防止金具１５が所定間隔ごとに取り付けられている。   Further, in a state in which the wiring 51 is accommodated, the drop-off prevention metal fitting 15 is attached at predetermined intervals so that the opening 12 is partially closed and the wiring 51 is not exposed from the accommodating portion 13.

次に、脱落防止金具１５を配線ダクト本体１１に取り付ける方法について説明する。
脱落防止金具１５を配線ダクト本体１１に取り付けるには、まず脱落防止金具１５の垂直板部３３と付勢板部３４の狭持片部３８との空間Ｄに、配線ダクト本体１１の下側折返し部２５を嵌合させる。なお、空間Ｄの幅Ｄ１は、配線ダクト本体１１の厚さＤ２よりも小さく形成されており、狭持片部３８は空間Ｄの幅Ｄ１を広げる方向に移動しようとする。このとき、付勢板部３４は例えばステンレスの薄板で形成されているため、元の位置に戻ろうとする付勢力が生じる。つまり、狭持片部３８が板バネとして機能する。したがって、垂直板部３３と狭持片部３８とで下側折返し部２５を強固に挟持しようとする力が生じる。 Next, a method for attaching the drop-off prevention metal fitting 15 to the wiring duct body 11 will be described.
In order to attach the drop-off prevention metal fitting 15 to the wiring duct main body 11, first, the lower side of the wiring duct main body 11 is folded into the space D between the vertical plate portion 33 of the drop-off prevention metal fitting 15 and the holding piece portion 38 of the biasing plate portion 34. The part 25 is fitted. The width D1 of the space D is formed to be smaller than the thickness D2 of the wiring duct body 11, and the holding piece 38 tends to move in the direction of increasing the width D1 of the space D. At this time, since the urging plate portion 34 is formed of, for example, a stainless steel thin plate, an urging force for returning to the original position is generated. That is, the holding piece portion 38 functions as a leaf spring. Therefore, a force is generated to firmly hold the lower folded portion 25 between the vertical plate portion 33 and the holding piece portion 38.

続いて、脱落防止金具１５を配線ダクト本体１１の外周面に沿うように配し、側壁押さえ部３１の付勢部３５を側壁部２１の外側面２１ａに当接させる。   Subsequently, the drop-off preventing metal fitting 15 is arranged along the outer peripheral surface of the wiring duct body 11, and the urging portion 35 of the side wall pressing portion 31 is brought into contact with the outer side surface 21 a of the side wall portion 21.

そして、配線ダクト本体１１の上板部２２と脱落防止金具１５の水平板部３２とが当接するように脱落防止金具１５を下方へ移動させると、脱落防止金具１５の取り付けが完了する。   Then, when the drop-off prevention metal fitting 15 is moved downward so that the upper plate portion 22 of the wiring duct body 11 and the horizontal plate portion 32 of the drop-off prevention metal fitting 15 come into contact with each other, the attachment of the drop-off prevention metal fitting 15 is completed.

本実施形態によれば、配線ダクト本体１１の開口部１２の端部に取り付ける脱落防止金具１５に付勢力を持たせ、付勢しながら開口部１２の端部を挟持できるようにすることにより、脱落防止金具１５を配線ダクト本体１１に強固に取り付けることができる。したがって、配線ダクト１０に振動などが生じても脱落防止金具１５は配線ダクト本体１１から脱落することがなくなり、配線５１を確実に収容することができる。   According to the present embodiment, the fall prevention metal fitting 15 attached to the end of the opening 12 of the wiring duct body 11 has a biasing force so that the end of the opening 12 can be clamped while being biased. The drop-off prevention metal fitting 15 can be firmly attached to the wiring duct body 11. Therefore, even if vibration or the like occurs in the wiring duct 10, the drop-off prevention metal fitting 15 does not drop off from the wiring duct main body 11, and the wiring 51 can be reliably accommodated.

具体的には、配線ダクト本体１１に取り付ける配線５１の脱落防止金具１５に付勢力を有する付勢板部３４を形成し、配線ダクト本体１１の一部である下側折返し部２５を付勢板部３４と垂直板部３３との間で付勢しながら挟持するようにしたため、脱落防止金具１５は配線ダクト本体１１に強固に取り付けられる。   Specifically, a biasing plate portion 34 having a biasing force is formed on the drop-off preventing metal fitting 15 of the wiring 51 attached to the wiring duct main body 11, and the lower folded portion 25 that is a part of the wiring duct main body 11 is biased to the biasing plate. Since the pin 34 is clamped while being urged between the portion 34 and the vertical plate portion 33, the drop-off prevention metal fitting 15 is firmly attached to the wiring duct body 11.

また、側壁押さえ部３１に付勢部３５を形成することにより、より強固に脱落防止金具１５を配線ダクト本体１１に取り付けることができる。また、付勢部３５を形成することにより、多少の寸法誤差が生じても吸収することができ、確実に脱落防止金具１５を配線ダクト本体１１に取り付けることができる。   Further, by forming the urging portion 35 in the side wall pressing portion 31, the drop-off preventing metal fitting 15 can be more firmly attached to the wiring duct body 11. Further, by forming the urging portion 35, it is possible to absorb even a slight dimensional error, and the drop-off preventing metal fitting 15 can be securely attached to the wiring duct body 11.

上述のように構成した脱落防止金具１５を用いることにより、振動が多く生じる列車のレール５０の近傍に配線ダクト１０を設置しても脱落防止金具１５が配線ダクト本体１１から脱落するのを防止することができる。また、列車のレール５０の下方には砕石５３が敷き詰められていることが多いが、脱落防止金具１５を配線ダクト本体１１に取り付ける際に、脱落防止金具１５が砕石５３と干渉することなく取り付けることができる。したがって、脱落防止金具１５を容易に、かつ確実に配線ダクト本体１１に取り付けることができる。つまり、レール５０に設けられる電気融雪器用の配線５１を確実に収容することが可能となる。   By using the drop-off prevention metal fitting 15 configured as described above, the drop-off prevention metal fitting 15 is prevented from falling off the wiring duct main body 11 even if the wiring duct 10 is installed in the vicinity of the rail 50 of the train where vibration is often generated. be able to. Further, the crushed stone 53 is often spread below the rail 50 of the train. However, when the fall prevention metal fitting 15 is attached to the wiring duct body 11, the fall prevention metal fitting 15 is attached without interfering with the crushed stone 53. Can do. Therefore, the drop-off prevention metal fitting 15 can be easily and reliably attached to the wiring duct body 11. In other words, it is possible to reliably accommodate the electric snow melter wiring 51 provided on the rail 50.

尚、本発明は、上述した実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において、上述した実施形態に種々の変更を加えたものを含む。すなわち、実施形態で挙げた具体的な材料や構成等は一例にすぎず、適宜変更が可能である。
例えば、本実施形態では、脱落防止金具の側壁押さえ部に付勢部を形成した場合の説明をしたが、図８に示すような形状の脱落防止金具１１５を用いてもよい。具体的に、脱落防止金具１１５は、側壁押さえ部１３１に付勢部を設けず、側壁押さえ部１３１自体が板バネの機能を有するように構成している。また、付勢板部１３４を断面で折れ線状に形成し、付勢板部１３４と垂直板部３３との間に下側折返し部２５を挟持するように構成している。なお、配線ダクト本体の側壁部および上板部に、脱落防止金具の側壁押さえ部および水平板部がそれぞれ当接するように構成すると、脱落防止金具を強固に配線ダクト本体に支持固定することができる。 Note that the present invention is not limited to the above-described embodiment, and includes various modifications made to the above-described embodiment without departing from the spirit of the present invention. That is, the specific materials, configurations, and the like given in the embodiment are merely examples, and can be changed as appropriate.
For example, in this embodiment, the case where the urging portion is formed on the side wall pressing portion of the drop-off prevention metal fitting has been described, but the drop-off prevention metal fitting 115 having a shape as shown in FIG. 8 may be used.
