Description

本発明は、積雪地帯に敷設された軌条の周囲に設置される消雪パネルに関する。   The present invention relates to a snow extinguishing panel installed around a rail laid in a snowy area.

積雪地帯に敷設された鉄道路線においては、列車を安全に運行するために、軌条の周囲に消雪パネルを設置し、消雪パネル上に堆積した雪（除雪された及び降雪した雪）を消雪パネルの裏面を流動する熱媒体（例えば地下水などの温水）で溶融することが行われている。   On railway lines laid in snowy areas, in order to operate the train safely, a snow-dissipating panel is installed around the rails, and the snow accumulated on the snow-dissipating panel (the snow removed and the snow that fell) is removed. Melting with the heat medium (for example, warm water, such as groundwater) which flows the back of a snow panel is performed.

この種の消雪装置として、例えば特許文献１には、上面が放熱面である薄い平板と、この平板の下面に接合した、複数列の幅広で浅い凹部、およびこの凹部各列となり同士をつなぐ幅広で浅い凹部、からなる連続した凹部を有する溝付板と、この溝付板の連続した幅広で浅い凹部と前記平板とで形成される幅広で浅い流路の両端に設けた配管接続口と、からなる消雪用放熱器において、前記平板と溝付板との周囲を取り囲む帯薄板に延長部を設けて、前記溝付板の下面と敷設面との間に間隙を設け、該間隙に向けて前記配管接続口を開口した消雪用放熱器が記載されている。また、溝付板の周囲を取り囲む帯薄板は箱形を形成させて消雪用放熱器の強度を大きくさせることが記載されている。   As this type of snow-absorbing device, for example, in Patent Document 1, a thin flat plate whose upper surface is a heat radiating surface, a plurality of rows of wide and shallow concave portions joined to the lower surface of the flat plate, and each row of the concave portions are connected to each other. A grooved plate having continuous recesses composed of wide and shallow recesses, and pipe connection ports provided at both ends of a wide and shallow flow path formed by the continuous wide and shallow recesses of the grooved plate and the flat plate, In the snow-dissipating heat dissipating device, an extension is provided on the thin strip that surrounds the flat plate and the grooved plate, and a gap is provided between the lower surface of the grooved plate and the laying surface. There is described a snow-dissipating heat radiator having the piping connection port opened. In addition, it is described that the belt thin plate surrounding the periphery of the grooved plate is formed in a box shape to increase the strength of the snow-dissipating radiator.

また、特許文献２には、特許文献１に記載の消雪用放熱器を水平に対して勾配を設けて設置することが記載されている。また、特許文献３には、特許文献１における溝付板を、台形状断面を有する直線溝部材と、Ｕ字溝部材とを接合して構成することが記載されている。そして、これらの消雪装置を構成する平板と溝付板とは専ら溶接接合されている。   Patent Document 2 describes that the snow-dissipating heat radiator described in Patent Document 1 is installed with a gradient with respect to the horizontal. Patent Document 3 describes that the grooved plate in Patent Document 1 is formed by joining a linear groove member having a trapezoidal cross section and a U-shaped groove member. And the flat plate and grooved plate which comprise these snow-melting apparatuses are exclusively welded.

特公平６−７６６８１号公報Japanese Examined Patent Publication No. 6-76681 特開平１１−１５２７０１号公報Japanese Patent Laid-Open No. 11-152701 特開２００７−８５０５７号公報JP 2007-85057 A

しかしながら、特許文献１及び２に記載のものでは、接合の際には、大きな溶接歪が発生する。特に、平板の一面と溝付板とを溶接接合するために、平板の放熱面が凹となる歪が生じやすく、消雪の際には凹部が水溜りとなり放熱面に錆びを発生させることとなる。そのために、溶接接合の後に歪取り工程を必要としていた。特許文献３に記載のものは、この歪取り工程の削減を図ったものであるが、溶接歪を低減することはできるものの、歪取り工程を撲滅するには至っていない。   However, in the ones described in Patent Documents 1 and 2, large welding distortion occurs during joining. In particular, since one surface of the flat plate and the grooved plate are welded together, the flat plate heat dissipation surface tends to be distorted, and when snow is removed, the concave portion becomes a water pool and rust is generated on the heat dissipation surface. Become. For this reason, a distortion removing process is required after welding and joining. Although the thing of patent document 3 aims at reduction of this distortion removal process, although welding distortion can be reduced, it has not led to eradicating the distortion removal process.

また、箱形に形成させた帯薄板を溶接で溝付板の周囲に溶接していては製造コストが嵩むという問題を有していた。更に、この種の消雪パネルは鋼板を主材料にして構成するので、その重量が約１００ｋｇになり、特許文献２に記載のようにメンテナンスのために開閉可能なように構成した場合、消雪パネルと設置ベースとの間に手を挟みやすいといった問題もあった。   In addition, if the belt-like sheet formed in a box shape is welded around the grooved plate, there is a problem that the manufacturing cost increases. Furthermore, since this type of snow-absorbing panel is made of steel plate as the main material, its weight is about 100 kg, and when it is configured to be openable and closable for maintenance as described in Patent Document 2, There was also a problem that hands were easily caught between the panel and the installation base.

本発明は、上記の事項に留意してなされたもので、製造コストを抑えるとともに放熱板の歪を低減させ、放熱板の歪から生じる水溜りや耐食性の問題を解消した消雪パネルを提供することを目的としている。また他の目的は、メンテナンス時においても安全に作業することのできる消雪パネルを提供することである。   The present invention has been made in consideration of the above-described matters, and provides a snow squeeze panel that reduces manufacturing costs and reduces distortion of the heat sink, and solves problems of water pool and corrosion resistance resulting from the distortion of the heat sink. The purpose is that. Another object of the present invention is to provide a snow extinguishing panel that can be safely operated even during maintenance.

本発明は、上面が放熱面である薄い放熱平板と、この放熱平板の下面に溶接接合し、その一方の表面と前記放熱平板との間に熱媒体が流動するつづら折り状の流路を形成する流路形成部材とを備えた消雪パネルにおいて、前記放熱平板の周囲をＬ字状に折り曲げ、更にこの折り曲げ部に帯板を溶接接合したことを特徴とする消雪パネルである。   In the present invention, a thin heat radiating flat plate whose upper surface is a heat radiating surface and a lower surface of the heat radiating flat plate are welded and joined, and a zigzag flow path in which a heat medium flows is formed between one surface and the heat radiating flat plate. A snow-melting panel comprising a flow path forming member, wherein the heat-dissipating flat plate is bent in an L shape and a band plate is welded to the bent portion.

上記の構成によれば、放熱平板の周囲をＬ字状に折り曲げ、更にこの折り曲げ部に帯板を溶接接合したことを特徴としているので、一旦放熱平板と流路形成部材との溶接接合によって、放熱平板の放熱面が凹となるような溶接歪が発生するものの、折り曲げ部に帯板を溶接接合することによって、放熱平板の放熱面が凸となるような溶接歪が発生する。したがって、消雪の際の放熱面の水溜りの発生を防止することができる。   According to said structure, since the circumference | surroundings of the thermal radiation flat plate were bent in L shape, and also it was characterized by having welded and joined the strip | belt plate to this bending part, once by the welding joining of a thermal radiation flat plate and a flow-path formation member, Although welding distortion occurs such that the heat dissipation surface of the heat dissipation flat plate is concave, welding distortion occurs such that the heat dissipation surface of the heat dissipation flat plate is convex by welding the band plate to the bent portion. Accordingly, it is possible to prevent the accumulation of water on the heat radiating surface during snow extinguishing.

また、本発明において、前記帯板の溶接接合部ではない他端側はＬ字状に折り曲げ加工されていることが望ましい。
この構成によれば、消雪パネル全体の強度を更に高められるとともに、帯板の先端で手を切創する事故を防止することができる。 Moreover, in this invention, it is desirable that the other end side which is not the welding junction part of the said strip is bent in the L shape.
According to this configuration, it is possible to further increase the strength of the entire snow-absorbing panel and to prevent an accident in which a hand is cut at the end of the band plate.

また、上記発明において、前記流路形成部材は前記熱媒体が流入する第１のノズル部材と、前記熱媒体が流出する第２のノズル部材と、これらの間に配設され台形状断面を有する複数列の直線溝部材と、相隣る直線溝部材の端部が接続される複数のＵ字溝部材とからなり、前記直線部材、前記第１、第２のノズル部材及びＵ字溝部材との連結部に継目部を設け、当該継目部は固着されると共に、前記各直線溝部材はその短手方向のツバ部が長手方向の全長にわたって前記放熱平板に溶接接合されることが好ましい。
上記の構成によれば、流路形成部材を放熱平板に溶接する際の溶接歪を低減できるとともに製造コストを抑えることができる。 In the above invention, the flow path forming member has a first nozzle member into which the heat medium flows in, a second nozzle member from which the heat medium flows out, and a trapezoidal cross section disposed therebetween. It consists of a plurality of linear groove members and a plurality of U-shaped groove members to which ends of adjacent linear groove members are connected, and the linear members, the first and second nozzle members, and the U-shaped groove members It is preferable that a seam portion is provided in the connecting portion, the seam portion is fixed, and a flange portion of each straight groove member is welded to the heat radiating plate over the entire length in the longitudinal direction.
According to said structure, while being able to reduce the welding distortion at the time of welding a flow-path formation member to a thermal radiation flat plate, manufacturing cost can be held down.

また、請求項１乃至３のいずれかに記載の消雪消雪パネルを線路に沿って複数枚配置し、各々の消雪パネルは一端から持ち上げ可能とするとともに、熱媒体の供給管および排出管にフレキシブル管を用いて並列に接続し、前記帯板には、取手を設けることができる。
この構成によれば、メンテナンスのために消雪パネルを開閉した場合においても消雪パネルと設置ベースとの間に手を挟んだりする事故を防止することができる。 Further, a plurality of snow-melting / snow-removing panels according to any one of claims 1 to 3 are disposed along the track, and each snow-snipping panel can be lifted from one end, and is provided in a heat medium supply pipe and a discharge pipe. A flexible tube is used for parallel connection, and the band plate can be provided with a handle.
According to this configuration, it is possible to prevent an accident in which a hand is caught between the snow removal panel and the installation base even when the snow removal panel is opened and closed for maintenance.

本発明にかかる消雪パネルによれば、放熱平板の周囲をＬ字状に折り曲げ、更にこの折り曲げ部に帯板を溶接接合したことを特徴としているので、一旦放熱平板と流路形成部材との溶接接合によって、放熱平板の放熱面が凹となるような溶接歪が発生するものの、折り曲げ部に帯板を溶接接合することによって、放熱平板の放熱面が凸となるような溶接歪が発生する。したがって、消雪の際の放熱面の水溜りの発生を防止することができる。   According to the snow extinguishing panel according to the present invention, the periphery of the heat radiating flat plate is bent in an L shape, and further, a band plate is welded and joined to the bent portion. Although welding distortion that causes the heat dissipation surface of the heat dissipation flat plate to be concave is generated by welding, welding distortion that causes the heat dissipation surface of the heat dissipation flat plate to be convex occurs by welding the band plate to the bent portion. . Accordingly, it is possible to prevent the accumulation of water on the heat radiating surface during snow extinguishing.

以下に、本発明に係る消雪パネルの一実施例を添付図面に基づいて詳述する。

Moreover, FIG. 8 is sectional drawing which shows the state which installed the snow-melting panel based on this invention.

図１及び図２に示すように、消雪パネル１は、略長方形の薄板鋼板製の放熱平板２と、流体が流入する第１ノズル部４１と流体が排出される第２ノズル部４３とを連なるように、つづら折り状に流路を形成する流路形成部材１０と、放熱平板２を囲むように設けた帯板２０とから主に構成している。流路形成部材１０は、薄板鋼板を断面略台径に折り曲げ加工した長尺の直線溝部材１１を複数列並べ、この直線溝部材１１の端部同士をＵ字溝部材１３で接続して第１ノズル部４１から第２ノズル部４３まで流体が流動する流路を形成している。また、消雪パネル１の長辺の一つには蝶番部１７が設けられ、短辺側の帯板２０には設置ベースに固定するための固定部４５が設けられている。更に、消雪パネル１全体がねじれたり変形したりしないように補強部材１５が（図中では３箇所）設けられている。   As shown in FIGS. 1 and 2, the snow-dissipating panel 1 includes a heat sink plate 2 made of a substantially rectangular thin steel plate, a first nozzle portion 41 into which a fluid flows, and a second nozzle portion 43 through which the fluid is discharged. It is mainly comprised from the flow-path formation member 10 which forms a flow path in a zigzag form so that it may continue, and the strip 20 provided so that the thermal radiation flat plate 2 may be enclosed. The flow path forming member 10 includes a plurality of long straight groove members 11 formed by bending thin steel plates into a substantially trapezoidal cross section, and a plurality of rows of straight groove members 11 are connected to each other by U-shaped groove members 13. A flow path in which fluid flows from the first nozzle portion 41 to the second nozzle portion 43 is formed. Moreover, the hinge part 17 is provided in one of the long sides of the snow-melting panel 1, and the fixing | fixed part 45 for fixing to the installation base is provided in the strip 20 of the short side. Further, reinforcing members 15 (three places in the figure) are provided so that the entire snow-dissipating panel 1 is not twisted or deformed.

放熱平板２は、図２に示すように、その周囲はＬ字状に折り曲げられた折り曲げ部２ａが形成されている。そして、帯板２０には、一端が消雪パネルの内側になるようにＬ字状に折り曲げられたエッジ部２３と、他端側が放熱平板２の折り曲げ部２ａと重なり合わせるための溶接部２１が形成されている。   As shown in FIG. 2, the heat radiating plate 2 has a bent portion 2 a that is bent in an L shape around the periphery thereof. The band plate 20 has an edge portion 23 that is bent in an L shape so that one end is inside the snow-melting panel, and a welded portion 21 that is overlapped with the bent portion 2a of the heat radiating plate 2 on the other end side. Is formed.

図３に示すように、直線溝部材１１は、その内部を流動する温水と放熱平板２との接触面積を広げるために、断面が台形状（上辺の幅Ｗｂ、底辺の幅Ｗａ）に形成され、両側の全長（Ｌ２）にわたってツバ部１１ａを有した長尺の部材である。   As shown in FIG. 3, the straight groove member 11 has a trapezoidal cross section (upper side width Wb, bottom side width Wa) in order to increase the contact area between the hot water flowing inside and the heat radiating plate 2. This is a long member having a flange 11a over the entire length (L2) on both sides.

また、図４に示すようにＵ字溝部材１３は、半円形部１３ａと、段付部１３ｂからなる。図６に示すように、各Ｕ字溝部材１３は、段付部１３ｂに直線溝部材１１の端部が差し込まれるように設置されている。これらのＵ字溝部材１３は、直線溝部材１１の両方の端部に並置されており、Ｕ字溝部材１３と直線溝部材１１とにより、相隣り合う直線溝部材同士が連通して、単一の流路が形成される（図１参照）。   Further, as shown in FIG. 4, the U-shaped groove member 13 includes a semicircular portion 13a and a stepped portion 13b. As shown in FIG. 6, each U-shaped groove member 13 is installed so that the end of the linear groove member 11 is inserted into the stepped portion 13b. These U-shaped groove members 13 are juxtaposed at both ends of the linear groove member 11, and the adjacent linear groove members communicate with each other by the U-shaped groove member 13 and the linear groove member 11. One flow path is formed (see FIG. 1).

続いて、消雪パネル１の製造工程について、図６、図７を参照して詳細に説明する。
まず、図６（ａ）に示すように、放熱平板２に直線溝部材１１を所定の数だけ複数本並べる。また、図示しないＵ字溝部材１３をつづら折流路を形成するように直線溝部材１１の端部に配置する（図１参照）。そして、直線溝部材１１の両端に形成したツバ部１１aと放熱平板２とを流路形成部材１０の全長に亘って、溶接接合する。溶接接合は、シーム溶接又はアーク溶接が好適である。 Then, the manufacturing process of the snow-melting panel 1 is demonstrated in detail with reference to FIG. 6, FIG.
First, as shown in FIG. 6A, a predetermined number of linear groove members 11 are arranged on the heat radiating plate 2. Further, a U-shaped groove member 13 (not shown) is arranged at the end of the linear groove member 11 so as to form a folded flow path (see FIG. 1). Then, the flange portions 11 a formed on both ends of the linear groove member 11 and the heat radiating flat plate 2 are welded over the entire length of the flow path forming member 10. The welded joint is preferably seam welding or arc welding.

このとき、放熱平板２には、流路形成部材１０を溶接接合する面のみが加熱されることとなる。すると、溶接を施したツバ部１１aが収縮し、直線溝部材１１の熱影響を受けていない部分（直線溝部材１１のツバ部１１aを除いた大部分）としては収縮しないので、図７（ａ）に示すように、薄板からなる放熱平板２の放熱面２ｂが凹面となるように歪が発生する。このままの状態では、消雪パネルで消雪した水が凹面に溜まり、その部分から放熱平板２を腐食させてしまうこととなる。   At this time, only the surface on which the flow path forming member 10 is welded and joined is heated on the heat radiating flat plate 2. Then, the flange portion 11a subjected to welding contracts and does not contract as a portion that is not affected by the thermal effect of the linear groove member 11 (most portion excluding the flange portion 11a of the linear groove member 11). As shown in (2), distortion occurs so that the heat radiating surface 2b of the thin heat radiating plate 2 is concave. In this state, the water that has been removed by the snow squeezing panel accumulates in the concave surface, and the heat radiating plate 2 is corroded from that portion.

そこで、図６（ｂ）に示すように、放熱平板２の周囲をプレス等を用いて折り曲げ加工して折り曲げ部２ａを形成する。そして、この折り曲げ部２ａに帯板２０の溶接部２１を重ね合わせ、溶接接合する。すると、図７（ｂ）に示すように、帯板２０の溶接の影響を受けて折り曲げ部２ａが収縮するので、放熱平板２の放熱面２ｂが凸面となるような歪を生じる。最後に、流路形成部材１０の両端に第１ノズル部材４１及び第２ノズル部材４３を接続し、溶融亜鉛メッキ処理を施して消雪パネル１が得られる。放熱面２ｂが凸面となるように設けていれば、放熱面に水が溜まることはなく、消雪パネルが腐食することを防止できる。
なお、溶接によって生じる歪量は、溶接長さや溶接熱量を調整することで、増減することが可能である。 Therefore, as shown in FIG. 6B, the periphery of the heat radiating plate 2 is bent using a press or the like to form a bent portion 2a. And the welding part 21 of the strip 20 is piled up on this bending part 2a, and it weld-joins. Then, as shown in FIG. 7 (b), the bent portion 2a contracts due to the influence of the welding of the band plate 20, so that the heat radiating surface 2b of the heat radiating plate 2 is distorted. Finally, the first nozzle member 41 and the second nozzle member 43 are connected to both ends of the flow path forming member 10 and subjected to a hot dip galvanizing process, so that the snow-melting panel 1 is obtained. If the heat dissipating surface 2b is provided as a convex surface, water does not accumulate on the heat dissipating surface, and the snow erasing panel can be prevented from corroding.
Note that the amount of distortion caused by welding can be increased or decreased by adjusting the welding length or the amount of welding heat.

続いて、消雪パネル１の使用状態について、図８を用いて詳細に説明する。
図８（ａ）に示すように、線路等の軌道に沿って、コンクリート製の基礎６１が設けられる。基礎６１には、雨水を排出したり電線等を配設したりするための側溝６３が形成されている。そして、側溝壁６５に沿って、消雪パネル１への熱媒体を給排水する供給管５１、排水管５３が設けられる。基礎６１の上には設置ベース５０が設けられ、この設置ベース５０の上に消雪パネル１が一辺を蝶番部１７（図１参照）で開閉可能なように設置される。 Then, the use condition of the snow-melting panel 1 is demonstrated in detail using FIG.
As shown in FIG. 8A, a concrete foundation 61 is provided along a track such as a track. The foundation 61 is formed with a side groove 63 for discharging rainwater or arranging electric wires or the like. A supply pipe 51 and a drain pipe 53 are provided along the side groove wall 65 to supply and drain the heat medium to the snow-melting panel 1. An installation base 50 is provided on the foundation 61, and the snow extinguishing panel 1 is installed on the installation base 50 so that one side can be opened and closed by a hinge portion 17 (see FIG. 1).

そして、消雪パネル１の第１ノズル、第２ノズルにはスイベルジョイント５７が接続され、供給管５１、排水管５３との間はフレキシブル管５５で接続されている。なお、この消雪パネル１は、軌道に沿って複数枚設置される。   A swivel joint 57 is connected to the first nozzle and the second nozzle of the snow extinguishing panel 1, and the supply pipe 51 and the drain pipe 53 are connected by a flexible pipe 55. Note that a plurality of the snow extinguishing panels 1 are installed along the track.

熱媒体には例えば不凍液が用いられ、積雪が始まると図示しないボイラ室で不凍液を１０℃程度に加熱して、ポンプによって供給管５１を経由し、消雪パネル１に供給される。消雪パネル１に積雪した雪は、ここで熱交換して融かされ、不凍液は排水管５３を経由してボイラ室へ戻され再び１０℃程度に加熱される。   For example, an antifreeze liquid is used as the heat medium. When snow accumulation starts, the antifreeze liquid is heated to about 10 ° C. in a boiler chamber (not shown), and is supplied to the snow erasing panel 1 via the supply pipe 51 by a pump. The snow that has accumulated on the snow-dissipating panel 1 is melted by heat exchange here, and the antifreeze is returned to the boiler chamber via the drain pipe 53 and heated to about 10 ° C. again.

ところで、側溝６３に配設した電線等のメンテナンスが必要な場合がある。その場合には、図８（ｂ）に示すように、取手５９を利用して消雪パネル１を上方に開くことができるようになっている。取手５９を用いて消雪パネル１の開閉作業を行うことで、指を挟んでしまうような事故を防止することができる。   By the way, there is a case where maintenance of an electric wire or the like disposed in the side groove 63 is necessary. In that case, as shown in FIG. 8 (b), the snow removal panel 1 can be opened upward using the handle 59. By using the handle 59 to open and close the snow-fighting panel 1, it is possible to prevent an accident such as a finger being caught.
