Description

本発明は、鉄道軌道に敷設される温風式融雪装置用絶縁ダクト及び温風式融雪装置に関し、特に鉄道線路の分岐器におけるレール間に敷設される温風式融雪装置及びそれを構成する温風式融雪装置用絶縁ダクトに関する。   The present invention relates to an insulating duct for a hot air type snow melting device and a hot air type snow melting device laid on a railroad track, and more particularly, to a hot air type snow melting device laid between rails in a railroad track branching device and the temperature constituting the hot air type snow melting device. The present invention relates to an insulation duct for a wind-type snow melting device.

鉄道線路の分岐器はポイント部、リード部、クロッシング部及びガイドレール等によって構成されており、ポイント後端からクロッシング部に向けて左右のレールの間隔が徐々に狭くなる（以下、分岐器において左右のレールの間隔が徐々に狭くなりクロッシング部までの領域をデルタエリアという）。そして、例えば鉄道車両に取り付けたスノープラウで雪が押されてくる等してデルタエリアに雪が溜まると、ポイントが動かなくなってポイント不転換が生じてしまう場合がある。   A railroad track branching device is composed of a point portion, a lead portion, a crossing portion, a guide rail, and the like, and the distance between the left and right rails gradually decreases from the rear end of the point toward the crossing portion (hereinafter referred to as left and right in the branching device). The space between the rails gradually becomes narrower and the area up to the crossing section is called the delta area). For example, if snow accumulates in the delta area, for example, when snow is pushed by a snow plow attached to a railway vehicle, the point may not move and point inversion may occur.

すなわち、図１０に示す分岐器に、スノープラウを取り付けた鉄道車両（不図示）が図中左側から進入すると、スノープラウで押された雪がデルタエリアＡに溜まる。また、スノープラウを取り付けた鉄道車両（不図示）が図中右側から進入すると、スノープラウで押された雪がデルタエリアＢに溜まる。なお、以下では、図１０に示したような分岐器に鉄道車両が図中左側から進入する場合（スノープラウで押された雪がデルタエリアＡに溜まる場合）を想定して説明するが、鉄道車両が図中右側から進入する場合（この場合は後述する温風式融雪装置用ダクト１０１はデルタエリアＢの図中右側に敷設される。）も同様に説明される。   That is, when a railway vehicle (not shown) with a snow plow enters the branching device shown in FIG. 10 from the left side in the figure, the snow pushed by the snow plow accumulates in the delta area A. Further, when a railway vehicle (not shown) to which a snow plow is attached enters from the right side in the figure, the snow pushed by the snow plow accumulates in the delta area B. In the following description, it is assumed that the railway vehicle enters the branching device as shown in FIG. 10 from the left side in the figure (when the snow pushed by the snow plow accumulates in the delta area A). Is also described in the same manner (in this case, a hot-air type snow melting device duct 101 described later is laid on the right side of the delta area B in the drawing).

そして、このようなデルタエリアＡに雪が溜まることを防止するため、分岐器のレール間に温風式融雪装置が敷設される場合がある（分岐器に敷設されたものではないが特許文献１参照）。図１０に示すように、温風式融雪装置には温風式融雪装置用ダクト１０１が設けられる。そして、軌道外に設けられた温風発生装置２０で発生された温風を、地下の送風ダクト２１を通して温風分配部１０に供給し、温風分配部１０で温風を前後方向に分配して温風式融雪装置用ダクト１０１に供給する。そして、温風式融雪装置用ダクト１０１で温風をレール５０に沿って前後方向に導くとともに、その側面に設けられた複数の孔１０２からそれぞれ各レール５０（基本レールやトングレール等を含む。）に向けて吹き出してレール間に溜まった雪を融かすように構成される。なお、温風式融雪装置用ダクトが各レールの外側にも敷設される場合もある。   In order to prevent snow from accumulating in such a delta area A, there is a case where a hot-air type snow melting device is laid between the rails of the branching device (see Patent Document 1 although not installed in the branching unit). ). As shown in FIG. 10, the hot air type snow melting apparatus is provided with a hot air type snow melting apparatus duct 101. Then, the hot air generated by the hot air generator 20 provided outside the track is supplied to the hot air distributor 10 through the underground air duct 21, and the hot air is distributed in the front-rear direction by the hot air distributor 10. To the hot air type snow melting device duct 101. The hot air type snow melting device duct 101 guides the hot air along the rails 50 in the front-rear direction, and each rail 50 (including a basic rail, a tongle rail, and the like) from a plurality of holes 102 provided on the side surface. It is configured to melt the snow accumulated between the rails. In addition, the hot-air type snow melting apparatus duct may be laid also outside each rail.

従来、温風式融雪装置用ダクト１０１は、安価で容易に加工可能な鋼等の金属製の角パイプで形成されることが多かった。そして、デルタエリアＡの多くの部分の雪を融かすために温風式融雪装置用ダクト１０１をクロッシング部Ｃ（図１０参照）に近い部分まで延ばすように構成すると、温風式融雪装置用ダクト１０１と各レール５０との距離が近くなるが、上記のように従来の温風式融雪装置用ダクト１０１は導電性であるため、温風式融雪装置用ダクト１０１を介してレール５０同士が短絡するおそれがある。そのため、温風式融雪装置用ダクト１０１をあまり延ばすことができず、その分、融雪面積を広げることが困難であった。   Conventionally, the hot air type snow melting device duct 101 is often formed of a square pipe made of metal such as steel that is inexpensive and can be easily processed. Then, in order to melt the snow in many parts of the delta area A, when the hot air type snow melting device duct 101 is extended to a portion close to the crossing portion C (see FIG. 10), the hot air type snow melting device duct is constructed. Although the distance between the rail 101 and each rail 50 is short, the conventional hot-air type snow melting device duct 101 is conductive as described above, so the rails 50 are short-circuited via the hot-air type snow melting device duct 101. There is a risk. Therefore, the hot air type snow melting device duct 101 cannot be extended so much, and it is difficult to increase the snow melting area accordingly.

本発明は、上記の問題点を鑑みてなされたものであり、鉄道線路の分岐器のデルタエリアにおける融雪面積をより広くすることが可能な温風式融雪装置用絶縁ダクト及び温風式融雪装置を提供することを目的とするものである。   The present invention has been made in view of the above problems, and an insulating duct for a hot air type snow melting device and a hot air type snow melting device capable of increasing the snow melting area in the delta area of a branching device of a railway track. Is intended to provide.

［温風式融雪装置］
本実施形態においても、図１０に示したように、温風式融雪装置は、鉄道線路の分岐器におけるレール間に敷設される温風式融雪装置用絶縁ダクトと、温風式融雪装置用絶縁ダクトに温風を供給する温風発生装置２０とを備えて構成されている。そして、温風式融雪装置用絶縁ダクトは、地下の送風ダクト２１や温風分配部１０を介して内部に供給された温風を、側面に設けられた複数の孔からそれぞれ各レール５０に向けて吹き出して、温風式融雪装置用絶縁ダクトとレール５０との間に溜まった雪を融かすようになっている。 [Hot air type snow melting equipment]
Also in this embodiment, as shown in FIG. 10, the hot air type snow melting device includes an insulating duct for the hot air type snow melting device laid between the rails in the branch of the railway track, and an insulation for the hot air type snow melting device. And a hot air generator 20 for supplying hot air to the duct. The insulating duct for the hot air type snow melting apparatus directs the hot air supplied to the inside through the underground air duct 21 and the hot air distributor 10 from the plurality of holes provided on the side surface to each rail 50. The snow accumulated between the insulating duct for the hot air type snow melting device and the rail 50 is melted.

［温風式融雪装置用絶縁ダクト］
図１（Ａ）〜（Ｃ）は本実施形態に係る温風式融雪装置用絶縁ダクトの構成を表す図であり、図１（Ａ）は平面図、図１（Ｂ）は正面図、図１（Ｃ）は図１（Ａ）におけるＸ−Ｘ線に沿う断面図である。本実施形態では、温風式融雪装置用絶縁ダクト１は、絶縁性材料で構成された断面コ字状の２つのカバー部材２Ａ、２Ｂを有しており、一方のカバー部材２Ａを他方のカバー部材２Ｂに向い合せて挿入することによりダクトが形成されている。そして、他方のカバー部材２Ｂに対する一方のカバー部材２Ａの挿入量Ｌ（図１（Ｃ）参照）をダクトの長手方向で変えることで、ダクトの短手方向の幅Ｗが、図１（Ａ）に示すようにダクトの長手方向に沿って可変とされている。すなわち、他方のカバー部材２Ｂへの一方のカバー部材２Ａの挿入量Ｌをダクトの長手方向の各位置で変えることで、ダクトの短手方向の幅Ｗをダクトの長手方向の各位置で変えることができるようになっている。 [Insulating duct for hot-air snow melting equipment]
1A to 1C are diagrams showing the configuration of an insulating duct for a hot-air snow melting device according to the present embodiment. FIG. 1A is a plan view, FIG. 1B is a front view, and FIG. 1 (C) is a cross-sectional view taken along line XX in FIG. 1 (A). In this embodiment, the insulating duct 1 for a hot-air snow melting device has two cover members 2A and 2B having a U-shaped cross section made of an insulating material, and one cover member 2A is connected to the other cover. A duct is formed by being inserted facing the member 2B. Then, by changing the insertion amount L (see FIG. 1C) of one cover member 2A with respect to the other cover member 2B in the longitudinal direction of the duct, the width W in the short direction of the duct is changed to FIG. As shown in FIG. 4, the length is variable along the longitudinal direction of the duct. That is, by changing the insertion amount L of one cover member 2A into the other cover member 2B at each position in the longitudinal direction of the duct, the width W in the short direction of the duct is changed at each position in the longitudinal direction of the duct. Can be done.

すなわち、例えば図１（Ａ）で温風分配部１０より右側に示すように、温風分配部１０からダクトの長手方向に離れるほど他方のカバー部材２Ｂに対する一方のカバー部材２Ａの挿入量Ｌを大きくすることでダクトの短手方向の幅Ｗが徐々に小さくなるように変化するように温風式融雪装置用絶縁ダクト１を構成することが可能である。また、例えば図１（Ａ）で温風分配部１０より左側に示すように、２つのカバー部材２Ａ、２Ｂで形成されるダクトの幅Ｗがダクトの長手方向に沿って一定になるようにすることも可能である。   That is, for example, as shown on the right side of the hot air distributor 10 in FIG. 1A, the insertion amount L of one cover member 2A with respect to the other cover member 2B is increased as the distance from the hot air distributor 10 in the longitudinal direction of the duct increases. It is possible to configure the insulating duct 1 for a hot-air snow melting device so that the width W in the short direction of the duct changes gradually by increasing the width. Further, for example, as shown on the left side of the warm air distributor 10 in FIG. 1A, the width W of the duct formed by the two cover members 2A and 2B is made constant along the longitudinal direction of the duct. It is also possible.

カバー部材２Ａ、２Ｂを構成する材料は、絶縁性を有するものであれば任意の材料を用いることが可能であるが、強度や耐久性、扱い易さ等の点から繊維強化プラスチック（fiber reinforced plastics：ＦＲＰ）、特にガラス繊維強化プラスチック（glass fiber reinforced plastics：ＧＦＲＰ）が好ましく用いられる。また、このダクト内に温風が供給されるため、カバー部材２Ａ、２Ｂは耐熱性を有することが好ましい。例えばガラス繊維強化プラスチックの表裏面をそれぞれクレー（粘度）でコートしたものを用いれば、さらに不燃性を有するようになるため、より好ましい。   Any material can be used as the material for the cover members 2A and 2B as long as it has an insulating property. However, fiber reinforced plastics (fiber reinforced plastics) can be used in terms of strength, durability, ease of handling, and the like. : FRP), particularly glass fiber reinforced plastics (GFRP) is preferably used. Moreover, since warm air is supplied into this duct, it is preferable that cover member 2A, 2B has heat resistance. For example, it is more preferable to use glass fiber reinforced plastics that are coated with clay (viscosity) on the front and back surfaces, respectively, because they have further nonflammability.

また、図１（Ｂ）に示すように、温風式融雪装置用絶縁ダクト１の両側面（カバー部材２Ａ、２Ｂの各側面）には、ダクト内に供給された温風をレールに向けてそれぞれ吹き出すための複数の孔３が形成されている。その際、温風分配部１０からダクト内に供給された温風が温風分配部１０に近い部分の孔３から多く吹き出されてしまうと、温風分配部１０からダクトの長手方向に離れた位置の孔３から温風が吹き出されなくなったり、温風の吹き出し量が少なくなったりするため、孔３の大きさや孔３を形成する長手方向の間隔等は、ダクトの長手方向の各位置でそれぞれ適切な量の温風が吹き出されるように適切に設定される。なお、図１（Ａ）、（Ｂ）や後述する図２（Ａ）における蓋４については後で説明する。   Further, as shown in FIG. 1B, the hot air supplied in the duct is directed toward the rails on both side surfaces (side surfaces of the cover members 2A and 2B) of the insulating duct 1 for the hot air type snow melting device. A plurality of holes 3 for blowing out each is formed. At that time, if a large amount of hot air supplied from the hot air distributor 10 into the duct is blown out from the hole 3 in the portion close to the hot air distributor 10, the hot air distributor 10 is separated from the longitudinal direction of the duct. Since the hot air is not blown out from the hole 3 at the position or the amount of hot air blown out is reduced, the size of the hole 3 and the interval in the longitudinal direction for forming the hole 3 are determined at each position in the longitudinal direction of the duct. Each is appropriately set so that an appropriate amount of hot air is blown out. The lid 4 in FIGS. 1A and 1B and FIG. 2A to be described later will be described later.

図１０に示したように、従来の金属等の導電性の材料で形成されていた温風式融雪装置用ダクト１０１を分岐器のデルタエリアＡの方向に延ばすと、温風式融雪装置用ダクト１０１と各レール５０との距離が近くなるため、温風式融雪装置用ダクト１０１を介してレール５０同士が短絡するおそれがある。そのため、図２（Ｂ）に示す従来の温風式融雪装置用ダクト１０１は、デルタエリアＡの方向に延ばすことができず、融雪面積をデルタエリアＡの方向に広げることが難しかった。なお、図２（Ａ）、（Ｂ）等において、符号５１は枕木を表す。   As shown in FIG. 10, when the hot air type snow melting device duct 101 formed of a conductive material such as a conventional metal is extended in the direction of the delta area A of the branching device, the hot air type snow melting device duct is formed. Since the distance between the rails 101 and the rails 50 becomes short, the rails 50 may be short-circuited via the hot-air snow melting device duct 101. Therefore, the conventional hot-air type snow melting apparatus duct 101 shown in FIG. 2B cannot be extended in the direction of the delta area A, and it is difficult to expand the snow melting area in the direction of the delta area A. 2A and 2B, reference numeral 51 denotes a sleeper.

それに対して、温風式融雪装置用絶縁ダクト１を上記の本実施形態のように構成すると、温風式融雪装置用絶縁ダクト１は絶縁性であるため、図２（Ａ）に示すように、温風式融雪装置用絶縁ダクト１をデルタエリアＡの方向に延ばして温風式融雪装置用絶縁ダクト１と各レール５０との距離が近くなっても、温風式融雪装置用絶縁ダクト１を介してレール５０同士が短絡することはない。そのため、本実施形態に係る温風式融雪装置用絶縁ダクト１は、デルタエリアＡの方向に延ばすことが可能となる。   On the other hand, when the insulating duct 1 for hot air type snow melting apparatus is configured as in the above-described embodiment, the insulating duct 1 for hot air type snow melting apparatus is insulative, and as shown in FIG. Even if the insulation duct 1 for the hot air type snow melting device is extended in the direction of the delta area A and the distance between the insulation duct 1 for the hot air type snow melting device and each rail 50 becomes short, the insulation duct 1 for the hot air type snow melting device. The rails 50 are not short-circuited via each other. Therefore, the hot air type snow melting device insulating duct 1 according to the present embodiment can be extended in the direction of the delta area A.

そのため、温風式融雪装置用絶縁ダクト１の側面から各レール５０に向かって温風が吹き出される面積が従来の温風式融雪装置用ダクト１０１よりデルタエリアＡの方向に広がるため、その分、融雪面積を広げることが可能となる。   Therefore, the area from which the hot air is blown out from the side surface of the insulating duct 1 for the hot air type snow melting device toward the rails 50 extends in the direction of the delta area A from the conventional hot air type snow melting device duct 101. The snow melting area can be expanded.

また、温風式融雪装置用絶縁ダクト１内を温風が通るため温風式融雪装置用絶縁ダクト１自体も熱を帯びる。そして、上記のように本実施形態に係る温風式融雪装置用絶縁ダクト１は従来の温風式融雪装置用ダクト１０１より長手方向の長さを長くすることができるため、その分、温風式融雪装置用絶縁ダクト１に接触する雪（温風式融雪装置用絶縁ダクト１上の雪や側面等に接触する雪）を従来の温風式融雪装置用ダクト１０１より多く融かすことが可能となり、この点においても、融雪面積を広げることが可能となる。   Further, since the warm air passes through the hot air type snow melting device insulating duct 1, the hot air type snow melting device insulating duct 1 itself is also heated. And since the insulation duct 1 for hot air type snow melting apparatuses according to the present embodiment can be made longer in the longitudinal direction than the conventional hot air type snow melting apparatus duct 101 as described above, Snow that contacts the insulating duct 1 for a snow melting device (snow on the insulating duct 1 for the hot air melting device 1 or snow that contacts the side surface) can be melted more than the conventional duct 101 for a warm snow melting device. In this respect, the snow melting area can be increased.

なお、ダクトの長手方向の長さを同一とする条件の下で、カバー部材をガラス繊維強化プラスチックで形成した本実施形態に係る温風式融雪装置用絶縁ダクト１の場合と鋼で形成した従来の温風式融雪装置用ダクト１０１の場合に、ダクトの末端部（温風分配部１０から最も遠い部分）の表面温度Ｔを測定したフィールド試験の結果の一例を図３に示す。このフィールド試験では、時刻ｔ０に温風分配部１０からダクト内への温風の供給を開始し、時刻ｔ１に温風の供給を停止した。 In addition, on the conditions which make the length of the longitudinal direction of a duct the same, the case of the insulation duct 1 for the hot-air type snow melting apparatus which concerns on this embodiment which formed the cover member with the glass fiber reinforced plastic, and the conventional steel FIG. 3 shows an example of the result of a field test in which the surface temperature T of the end portion of the duct (the portion farthest from the hot air distributor 10) is measured in the case of the hot air type snow melting device duct 101. In this field test, starting the supply of the hot air from the hot air distribution unit 10 at time t 0 into the duct, and stop the supply of hot air at time t 1.

図３に示すように、カバー部材２Ａ、２Ｂをガラス繊維強化プラスチックで形成した本実施形態に係る温風式融雪装置用絶縁ダクト１の場合（図中α参照）と鋼で形成した従来の温風式融雪装置用ダクト１０１の場合（図中β参照）とを比較すると、温風分配部１０からダクト内への温風の供給を開始した時点では、ほぼ同様に表面温度Ｔが上昇するが、温風分配部１０からダクト内への温風の供給を停止すると、鋼で形成した従来の温風式融雪装置用ダクト１０１の場合は比較的速やかに表面温度Ｔが低下するのに対し、ガラス繊維強化プラスチックで形成した本実施形態に係る温風式融雪装置用絶縁ダクト１の場合は表面温度Ｔの低下が緩慢であり、温風分配部１０からダクト内への温風の供給を停止しても表面温度Ｔが高温の状態が長く保たれることが分かった。   As shown in FIG. 3, in the case of the insulation duct 1 for a hot-air type snow melting apparatus according to the present embodiment in which the cover members 2A and 2B are formed of glass fiber reinforced plastic (see α in the figure) and the conventional temperature formed of steel. When compared with the case of the wind-type snow melting device duct 101 (see β in the figure), the surface temperature T rises almost in the same manner when the supply of warm air from the warm air distributor 10 into the duct is started. When the supply of hot air from the hot air distributor 10 into the duct is stopped, the surface temperature T decreases relatively quickly in the case of the conventional hot air type snow melting device duct 101 formed of steel, In the case of the insulating duct 1 for hot air type snow melting apparatus according to the present embodiment formed of glass fiber reinforced plastic, the decrease in the surface temperature T is slow, and the supply of hot air from the hot air distributor 10 into the duct is stopped. Even if the surface temperature T is high, I understood that it was kept.

これは、本実施形態に係る温風式融雪装置用絶縁ダクト１のカバー部材２Ａ、２Ｂをガラス繊維強化プラスチックで形成した場合の方が、カバー部材を鋼で形成した従来の温風式融雪装置用ダクト１０１の場合よりもカバー部材の比熱が高いためと考えられる。このように、本実施形態のように温風式融雪装置用絶縁ダクト１のカバー部材２Ａ、２Ｂを繊維強化プラスチック（ＦＲＰ）やガラス繊維強化プラスチック（ＧＦＲＰ）等のプラスチックを用いて構成すれば、温風分配部１０からダクト内への温風の供給を停止しても温風式融雪装置用絶縁ダクト１のカバー部材２Ａ、２Ｂの表面温度Ｔが高温の状態を長く保つことが可能となる。   This is because when the cover members 2A and 2B of the insulating duct 1 for the hot air type snow melting device according to the present embodiment are formed of glass fiber reinforced plastic, the conventional hot air type snow melting device in which the cover member is formed of steel. This is probably because the specific heat of the cover member is higher than in the case of the duct 101 for use. As described above, if the cover members 2A and 2B of the insulating duct 1 for the hot air type snow melting apparatus are configured using plastics such as fiber reinforced plastic (FRP) and glass fiber reinforced plastic (GFRP) as in this embodiment, Even if the supply of hot air from the hot air distributor 10 into the duct is stopped, the surface temperature T of the cover members 2A and 2B of the insulating duct 1 for the hot air type snow melting device can be kept high for a long time. .

上記のように、本実施形態に係る温風式融雪装置用絶縁ダクト１では融雪面積を広げることが可能となる。そして、このように融雪面積が広がると、分岐器のデルタエリアＡや温風式融雪装置用絶縁ダクト１の周囲に雪が全くない部分を作ることができる。そして、このように雪が全くない部分があると、例えば鉄道車両がスノープラウで雪を押しながら分岐器に進入しても、押されてきた雪がこの雪が全くない部分に均されていく、すなわち雪がその部分の温風式融雪装置用絶縁ダクト１とレール５０との間や温風式融雪装置用絶縁ダクト１上に溜まっていく状態になり、少なくともクロッシング部Ｃ（図１０参照）まで雪は運ばれない。   As described above, the snow melting area can be expanded in the hot air type snow melting device insulating duct 1 according to the present embodiment. And if a snowmelt area spreads in this way, the part which does not have snow at all around the delta area A of a branching device and the insulation duct 1 for hot air type snowmelt devices can be made. And if there is a part where there is no snow in this way, for example, even if a railway vehicle enters the branching device while pushing snow with a snow plow, the pushed snow will be leveled into a part where there is no snow, that is, the snow The hot air type snow melting device insulating duct 1 and the rail 50 in that portion or the hot air type snow melting device insulating duct 1 are accumulated and the snow is transported to at least the crossing section C (see FIG. 10). I can't.

そして、温風式融雪装置用絶縁ダクト１とレール５０との間に溜まった雪は、温風式融雪装置用絶縁ダクト１から吹き出される温風によって融かされる。また、温風式融雪装置用絶縁ダクト１上に溜まった雪は、温風式融雪装置用絶縁ダクト１自体の熱で融かされる。そのため、再び、分岐器のデルタエリアＡや温風式融雪装置用絶縁ダクト１の周囲に雪が全くない部分が作られる。このように、本実施形態に係る温風式融雪装置用絶縁ダクト１によれば、融雪面積を的確に広げることが可能となり、分岐器のデルタエリアＡや温風式融雪装置用絶縁ダクト１の周囲に雪が全くない部分を作ることが可能となるため、例えば分岐器に進入する鉄道車両のスノープラウで雪が押されてくる等しても、デルタエリアＡに雪を持ち込ませないようにすることが可能となり、ポイントが動かなくなってポイント不転換が生じてしまう等の問題が生じることを的確に防止することが可能となる。   Then, the snow accumulated between the hot air type snow melting device insulating duct 1 and the rail 50 is melted by the hot air blown out from the hot air type snow melting device insulating duct 1. Further, the snow accumulated on the insulating duct 1 for the hot air type snow melting apparatus is melted by the heat of the insulating duct 1 for the hot air type snow melting apparatus itself. For this reason, again, a portion where there is no snow is formed around the delta area A of the branching unit and the insulating duct 1 for the hot air type snow melting device. As described above, according to the insulating duct 1 for a hot air type snow melting apparatus according to the present embodiment, it is possible to accurately expand the snow melting area, and the delta area A of the branching unit or the insulating duct 1 for the hot air type snow melting apparatus. Since it is possible to create a part where there is no snow in the surroundings, for example, even if snow is pushed by a snow plow of a railroad car entering a branching device, snow should not be brought into Delta Area A This makes it possible to accurately prevent problems such as the point not being moved and causing point inversion.

一方、上記のように、本実施形態に係る温風式融雪装置用絶縁ダクト１は、他方のカバー部材２Ｂに対する一方のカバー部材２Ａの挿入量Ｌをダクトの長手方向の各位置で調整することで、ダクトの短手方向の幅Ｗをダクトの長手方向で変化させて温風式融雪装置用絶縁ダクト１の形状を種々変化させることができるようになっている。そのため、温風式融雪装置用絶縁ダクト１を上方から見た場合の形状を、図２（Ａ）の右側に示すように台形状（あるいは三角形状。以下同じ。）に形成したり、あるいは図２（Ａ）の左側に示すように長方形状に形成したりすることができる。   On the other hand, as described above, the hot air type snow melting device insulating duct 1 according to the present embodiment adjusts the insertion amount L of one cover member 2A with respect to the other cover member 2B at each position in the longitudinal direction of the duct. Thus, the width W in the short direction of the duct can be changed in the longitudinal direction of the duct so that the shape of the insulating duct 1 for the hot-air snow melting device can be variously changed. Therefore, the shape when the insulating duct 1 for the hot air type snow melting apparatus is viewed from above is formed into a trapezoidal shape (or a triangular shape, the same applies hereinafter) as shown on the right side of FIG. It can be formed in a rectangular shape as shown on the left side of 2 (A).

そのため、温風式融雪装置用絶縁ダクト１の形状を、分岐器のデルタエリアＡの形状にあわせて変えることができる。すなわち、例えば温風式融雪装置用絶縁ダクト１の形状を分岐器の番号（すなわち分岐したレールが基本レールから１ｍ離れるために分岐点から何ｍ進むか）や両開き、片開き等の形状等にあわせて温風式融雪装置用絶縁ダクト１の形状を変えることが可能となる。そのため、温風式融雪装置用絶縁ダクト１の形状をデルタエリアＡの形状にあわせて変えることで、デルタエリアＡを含む分岐器のレール間に溜まった雪に対して温風を的確に吹き出すことが可能となり、融雪を的確に行うことが可能となる。そのため、この点においても融雪面積を拡大することが可能となる。   Therefore, the shape of the insulating duct 1 for the hot-air snow melting device can be changed according to the shape of the delta area A of the branching device. That is, for example, the shape of the insulation duct 1 for the hot-air snow melting device is changed to the number of the branching unit (that is, how many meters the branching rail travels from the branching point because it is 1 m away from the basic rail), the shape of double-opening, single-opening etc In addition, it is possible to change the shape of the insulating duct 1 for the hot-air snow melting device. Therefore, by changing the shape of the insulation duct 1 for the hot air type snow melting apparatus in accordance with the shape of the delta area A, the hot air is accurately blown out against the snow accumulated between the rails of the branching unit including the delta area A. This makes it possible to accurately melt snow. Therefore, the snow melting area can be enlarged also in this respect.

この場合、本実施形態のように構成する代わりに、例えば、１枚の絶縁板を折り曲げる等してダクトを形成するようにしても温風式融雪装置用絶縁ダクトを所定の形状に形成することができる。しかし、このように構成すると、デルタエリアＡの形状は分岐器ごとに異なるため、１枚の絶縁板を折り曲げる等して形成した温風式融雪装置用絶縁ダクトは、その分岐器にしか用いることができない。すなわち、分岐器ごとに温風式融雪装置用絶縁ダクトを形成しなければならなくなる。   In this case, instead of configuring as in the present embodiment, the insulating duct for the hot air type snow melting apparatus is formed in a predetermined shape even if the duct is formed by bending one insulating plate, for example. Can do. However, since the shape of the delta area A is different for each branching device with such a configuration, the insulating duct for the hot air type snow melting device formed by bending one insulating plate is used only for the branching unit. I can't. That is, it is necessary to form an insulating duct for a hot air type snow melting device for each branching device.

それに対し、本実施形態の温風式融雪装置用絶縁ダクト１のように構成すれば、分岐器のデルタエリアＡの形状にあわせて、他方のカバー部材２Ｂに対する一方のカバー部材２Ａの挿入量Ｌを変化させて温風式融雪装置用絶縁ダクト１をデルタエリアＡの形状にあった形状とすることができる。そのため、本実施形態によれば、分岐器ごとに温風式融雪装置用絶縁ダクト１を形成する必要はなく、分岐器のどのような形状のデルタエリアＡに対しても、本実施形態に係る温風式融雪装置用絶縁ダクト１を、その形状を可変させて用いることが可能となるといったメリットがある。   On the other hand, if the insulating duct 1 for the hot air type snow melting device of the present embodiment is configured, the insertion amount L of one cover member 2A with respect to the other cover member 2B in accordance with the shape of the delta area A of the branching device. Thus, the insulation duct 1 for the hot air type snow melting apparatus can be made to have a shape that matches the shape of the delta area A. Therefore, according to this embodiment, it is not necessary to form the insulating duct 1 for a hot-air snow melting device for each branch device, and according to this embodiment for any shape of the delta area A of the branch device. There is an advantage that the insulating duct 1 for a hot air type snow melting apparatus can be used with its shape varied.

［温風式融雪装置用絶縁ダクトの各部の構成］
ところで、温風式融雪装置用絶縁ダクト１のカバー部材２Ａは、複数のカバー部材２Ａの長手方向の端部同士を接着又は孔をあけてリベットでかしめる等して容易に延長することができる。カバー部材２Ｂについても同様である。また、上記のように一方のカバー部材２Ａとそれを挿入する他方のカバー部材２Ｂとがダクトの短手方向に広がらないように固定する際も、両者を接着又はリベットでかしめる等して固定することができる。他方のカバー部材２Ｂに一方のカバー部材２Ａを向い合せて挿入した状態で、それらの周囲に固定ベルトを巻き付け接着する等して両者を固定するようにしてもよい。 [Configuration of each part of insulation duct for hot-air snow melting equipment]
By the way, the cover member 2A of the insulation duct 1 for the hot-air snow melting device can be easily extended by bonding or punching the ends of the plurality of cover members 2A in the longitudinal direction with rivets. . The same applies to the cover member 2B. In addition, when one cover member 2A and the other cover member 2B into which the cover member 2B is inserted are fixed so as not to spread in the short direction of the duct as described above, they are fixed by bonding or caulking them with a rivet. can do. In a state where one cover member 2A is inserted facing the other cover member 2B, both may be fixed by wrapping and adhering a fixing belt around them.

また、温風式融雪装置用絶縁ダクト１のカバー部材２Ａ、２Ｂの末端部、すなわちカバー部材２Ａ、２Ｂで形成されるダクトの末端部が開放されていると、その末端部の開口から温風が流れ出すようになり、側面に設けられた孔３（図１（Ｂ）参照）から温風が適切に吹き出さなくなる場合がある。そのため、本実施形態では、温風式融雪装置用絶縁ダクト１のカバー部材２Ａ、２Ｂの末端部を、例えば図４（Ａ）、（Ｂ）に示すような蓋４で覆うようになっている。   Further, when the end portions of the cover members 2A and 2B of the insulating duct 1 for the hot air type snow melting apparatus, that is, the end portions of the duct formed by the cover members 2A and 2B are opened, May flow out, and the hot air may not be properly blown out from the hole 3 (see FIG. 1B) provided on the side surface. Therefore, in the present embodiment, the end portions of the cover members 2A and 2B of the insulating duct 1 for the hot-air snow melting device are covered with a lid 4 as shown in FIGS. 4A and 4B, for example. .

この場合、蓋４を一体の部材として構成することも可能であるが、本実施形態では、温風式融雪装置用絶縁ダクト１が一方のカバー部材２Ａを他方のカバー部材２Ｂに向い合せて挿入して形成されていることにあわせて、蓋４も２つの蓋部材４Ａ、４Ｂを組み合わせて形成されるようになっている。   In this case, it is possible to configure the lid 4 as an integral member, but in this embodiment, the insulating duct 1 for the hot air type snow melting apparatus is inserted with the one cover member 2A facing the other cover member 2B. Accordingly, the lid 4 is also formed by combining two lid members 4A, 4B.

角鋼で形成した従来の温風式融雪装置用ダクト１０１の場合には、ダクトの末端部の幅が変わらないため、末端部の開口部分に鋼板を溶接するによって末端部の開口を封止することができた。しかし、本実施形態の場合には、他方のカバー部材２Ｂに対する一方のカバー部材２Ａの挿入量Ｌが変わるとカバー部材２Ａ、２Ｂの末端部の幅Ｗが変わるため、板状部材で末端部の開口を封止する場合には、カバー部材２Ａ、２Ｂの末端部の幅Ｗに合わせていちいち板状部材を切り出さなければならなくなり不便である。
そのため、上記の本実施形態に係る蓋４のように構成すれば、他方のカバー部材２Ｂに対する一方のカバー部材２Ａの挿入量Ｌが変わるとカバー部材２Ａ、２Ｂの末端部の幅Ｗが変わるが、それにあわせて２つの蓋部材４Ａ、４Ｂの重なり幅を変えることで、蓋４の幅をカバー部材２Ａ、２Ｂの末端部の幅Ｗに適切にフィットさせることが可能となり、蓋４でダクトの末端部の開口を適切にかつ容易に封止することが可能となる。なお、この場合も、蓋４をカバー部材２Ａ、２Ｂの末端部に接着又はリベットでかしめる等して固定する。 In the case of the conventional hot-air type snow melting device duct 101 made of square steel, since the width of the end portion of the duct does not change, the opening of the end portion is sealed by welding a steel plate to the opening portion of the end portion. I was able to. However, in the case of this embodiment, if the insertion amount L of one cover member 2A with respect to the other cover member 2B changes, the width W of the end portions of the cover members 2A and 2B changes, so When sealing the opening, it is inconvenient because the plate-like member must be cut out in accordance with the width W of the end portions of the cover members 2A and 2B.
Therefore, if the cover 4 according to the present embodiment is configured, the width W of the end portions of the cover members 2A and 2B changes when the insertion amount L of the one cover member 2A with respect to the other cover member 2B changes. Accordingly, by changing the overlapping width of the two lid members 4A and 4B, it becomes possible to appropriately fit the width of the lid 4 to the width W of the end portions of the cover members 2A and 2B. It becomes possible to seal the opening of the end portion appropriately and easily. In this case as well, the lid 4 is fixed to the end portions of the cover members 2A and 2B by bonding or riveting.

一方、温風式融雪装置用絶縁ダクト１を構成する各カバー部材２Ａ、２Ｂが、上記のようにそれぞれ断面コ字状であると、例えば、温風式融雪装置用絶縁ダクト１の上に雪が溜まる等して温風式融雪装置用絶縁ダクト１に上方から力が加わった際に、温風式融雪装置用絶縁ダクト１が押し潰されてしまう可能性がある。   On the other hand, if each cover member 2A, 2B constituting the hot air type snow melting device insulating duct 1 has a U-shaped cross section as described above, for example, snow is formed on the hot air type snow melting device insulating duct 1. When a force is applied to the hot air type snow melting device insulation duct 1 from above due to accumulation or the like, the hot air type snow melting device insulation duct 1 may be crushed.

そこで、本実施形態では、図１（Ｃ）に示すように、他方のカバー部材２Ｂ内に挿入される一方のカバー部材２Ａの内部の、該一方のカバー部材２Ａの上壁と下壁との間に、補強板５が立設されている。このように構成すれば、温風式融雪装置用絶縁ダクト１に上方から力が加わっても温風式融雪装置用絶縁ダクト１が押し潰されることを的確に防止することが可能となる。また、補強板５を一方のカバー部材２Ａのみに設けることで、一方のカバー部材２Ａを他方のカバー部材２Ｂに向い合せて挿入する際に補強板５が挿入の邪魔にならない。   Therefore, in the present embodiment, as shown in FIG. 1C, the upper wall and the lower wall of the one cover member 2A inside the one cover member 2A inserted into the other cover member 2B. A reinforcing plate 5 is erected between them. If comprised in this way, even if force is applied to the insulation duct 1 for hot air type snow melting apparatuses from the upper direction, it becomes possible to prevent accurately the insulation duct 1 for hot air type snow melting apparatuses from being crushed. Further, by providing the reinforcing plate 5 only on one cover member 2A, the reinforcing plate 5 does not interfere with insertion when the one cover member 2A is inserted facing the other cover member 2B.

しかし、一方のカバー部材２Ａ内に単に補強板５を立設するだけだと、カバー部材２Ａ、２Ｂで形成されるダクトの内部が補強板５で仕切られてしまい、カバー部材２Ａ内を通る温風とカバー部材２Ｂ内を通る温風が流通しあわなくなってダクト内の温風の熱や温度分布が均一でなくなる可能性がある。そのため、本実施形態では、カバー部材２Ａの内部を通る温風とカバー部材２Ｂの内部を通る温風とを流通させるために、図５に示すように、カバー部材２Ａの補強板５に複数の開口部５ａが設けられている。   However, if the reinforcing plate 5 is simply erected in the one cover member 2A, the inside of the duct formed by the cover members 2A and 2B is partitioned by the reinforcing plate 5, and the temperature passing through the cover member 2A is increased. There is a possibility that the heat and the temperature distribution of the warm air in the duct are not uniform because the wind and the warm air passing through the cover member 2B do not circulate. Therefore, in this embodiment, in order to distribute the warm air passing through the inside of the cover member 2A and the warm air passing through the inside of the cover member 2B, a plurality of reinforcing plates 5 of the cover member 2A are provided on the reinforcing plate 5 as shown in FIG. An opening 5a is provided.

このように補強板５に複数の開口部５ａを設けることで、各開口部５ａを通じてカバー部材２Ａの内部を通る温風とカバー部材２Ｂの内部を通る温風とが流通するようになり、カバー部材２Ａ、２Ｂで形成されるダクト内の温風の熱や温度分布を均一にすることが可能となる。なお、開口部５ａの大きさを大きくし過ぎたり、開口部５ａ同士の間隔が短過ぎると、補強板５の強度が低下して、温風式融雪装置用絶縁ダクト１に上方から力が加わった場合に温風式融雪装置用絶縁ダクト１が押し潰されるおそれがある。そのため、補強板５に設ける開口部５ａの大きさや間隔等は、温風の流通し易さや補強板５の強度等に基づいて適宜決められる。   By providing the plurality of openings 5a in the reinforcing plate 5 in this way, the warm air passing through the inside of the cover member 2A and the hot air passing through the inside of the cover member 2B are circulated through each opening 5a, and the cover It becomes possible to make the heat and temperature distribution of the warm air in the duct formed by the members 2A and 2B uniform. If the size of the opening 5a is too large or the interval between the openings 5a is too short, the strength of the reinforcing plate 5 is reduced, and a force is applied to the insulating duct 1 for the hot-air snow melting device from above. In such a case, the hot air type snow melting device insulating duct 1 may be crushed. Therefore, the size, interval, and the like of the openings 5a provided in the reinforcing plate 5 are appropriately determined based on the ease of circulating hot air, the strength of the reinforcing plate 5, and the like.

［温風式融雪装置用絶縁ダクトの浮き上がりや位置ずれを防止するための構造］
温風式融雪装置用絶縁ダクト１を分岐器の枕木５１上に単に載置しただけだと、鉄道車両が分岐器を通過する際の振動で、温風式融雪装置用絶縁ダクト１が浮き上がったり（すなわち上方に移動したり）、レール５０に向かう方向（すなわちダクトの短手方向）やレール５０に沿う方向（すなわちダクトの長手方向）に位置ずれを生じてしまう可能性がある。そこで、本実施形態では、以下のようにして、温風式融雪装置用絶縁ダクト１の浮き上がりや位置ずれを防止するようになっている。 [Structure to prevent lifting and displacement of insulation duct for hot air type snow melting equipment]
If the insulation duct 1 for the hot air type snow melting device is simply placed on the sleeper 51 of the branching device, the insulation duct 1 for the hot air type snow melting device may be lifted by vibrations when the railway vehicle passes through the branching device. There is a possibility that displacement occurs in the direction toward the rail 50 (that is, the short direction of the duct) and the direction along the rail 50 (that is, the longitudinal direction of the duct). Therefore, in the present embodiment, the hot air type snow melting device insulating duct 1 is prevented from being lifted or displaced as follows.

本実施形態では、温風式融雪装置用絶縁ダクト１の浮き上がりを防止するために、図６に示すような浮き上がり防止用金具６が用いられている。本実施形態では、浮き上がり防止用金具６は、取付板６ａと係合部６ｂとを有しており、取付板６ａの一端側が係合部６ｂに溶接等により取り付けられている。そして、係合部６ｂを、下に枕木５１がない部分のレール５０の下部に係合させることでレール５０に固定され、浮き上がり防止用金具６がレール５０に取り付けられるようになっている。なお、浮き上がり防止用金具６をレール５０に取り付ける代わりに枕木５１に取り付けるように構成することも可能である。   In the present embodiment, in order to prevent the hot air type snow melting device insulating duct 1 from being lifted, a lifting preventing metal fitting 6 as shown in FIG. 6 is used. In the present embodiment, the lifting prevention metal fitting 6 has an attachment plate 6a and an engagement portion 6b, and one end side of the attachment plate 6a is attached to the engagement portion 6b by welding or the like. Then, the engaging portion 6 b is fixed to the rail 50 by engaging with the lower portion of the rail 50 where the sleepers 51 are not provided below, and the lifting prevention metal fitting 6 is attached to the rail 50. In addition, it is also possible to constitute the lifting prevention metal fitting 6 so as to be attached to the sleepers 51 instead of being attached to the rails 50.

そして、レール５０に取り付けた浮き上がり防止用金具６の取付板６ａの他端側（係合部６ｂに取り付けられている側とは反対側）が、温風式融雪装置用絶縁ダクト１の側面に形成されたスリットＳに挿入されるようになっている。そして、温風式融雪装置用絶縁ダクト１のスリットＳに挿入された浮き上がり防止用金具６の取付板６ａにより温風式融雪装置用絶縁ダクト１が上下方向に動くことが抑制されるため、鉄道車両が分岐器を通過する際に振動が生じる等しても浮き上がり防止用金具６により温風式融雪装置用絶縁ダクト１が浮き上がることを的確に防止することが可能となる。   And the other end side (the side opposite to the side attached to the engaging part 6b) of the mounting plate 6a of the lifting prevention metal fitting 6 attached to the rail 50 is on the side surface of the insulating duct 1 for the hot-air snow melting device. It is inserted into the formed slit S. Since the hot air type snow melting device insulating duct 1 is prevented from moving in the vertical direction by the mounting plate 6a of the lifting prevention metal fitting 6 inserted into the slit S of the hot air type snow melting device insulating duct 1, the railroad Even if vibrations occur when the vehicle passes through the branching device, it is possible to accurately prevent the insulating duct 1 for the hot air type snow melting apparatus from being lifted by the lifting preventing metal fitting 6.

なお、温風式融雪装置用絶縁ダクト１の側面に形成されたスリットＳと、それに挿入された浮き上がり防止用金具６の取付板６ａとの隙間の大きさは、その隙間から吹き出す温風の量が、温風式融雪装置用絶縁ダクト１の側面に形成された孔３（図１（Ｂ）参照）から吹き出す温風の量と同程度になるような大きさになるように適切に調整される。
また、本実施形態では、浮き上がり防止用金具６（取付板６ａ、係合部６ｂ）は金属で形成されている。そして、この場合、浮き上がり防止用金具６の取付板６ａが挿入されるスリットＳを、図７（Ａ）に示すように温風式融雪装置用絶縁ダクト１の左右の側面の、ダクトの長手方向の同じ位置にそれぞれ設けると、各スリットＳに挿入された浮き上がり防止用金具６の取付板６ａの端部同士が接近してしまい、左右のレール５０にそれぞれ取り付けられた各浮き上がり防止用金具６を介して左右のレール５０同士が短絡してしまう可能性がある。 The size of the gap between the slit S formed on the side surface of the insulating duct 1 for the hot air type snow melting device and the mounting plate 6a of the lifting prevention metal fitting 6 inserted into the slit S is the amount of hot air blown from the gap. Is appropriately adjusted so as to be the same size as the amount of hot air blown out from the hole 3 (see FIG. 1B) formed in the side surface of the insulating duct 1 for the hot air type snow melting device. The
In the present embodiment, the lifting prevention metal fitting 6 (the mounting plate 6a and the engaging portion 6b) is made of metal. In this case, the slit S into which the mounting plate 6a of the lifting prevention metal fitting 6 is inserted is formed in the longitudinal direction of the duct on the left and right side surfaces of the insulating duct 1 for the hot-air snow melting device as shown in FIG. Are provided at the same positions, the ends of the mounting plates 6a of the lifting prevention metal fittings 6 inserted into the slits S approach each other, and the lifting prevention metal fittings 6 attached to the left and right rails 50 are respectively attached. There is a possibility that the left and right rails 50 may be short-circuited.

そこで、浮き上がり防止用金具６を金属で形成する場合には、図７（Ｂ）に示すように、スリットＳを、温風式融雪装置用絶縁ダクト１の左右の側面で、ダクトの長手方向の互いに異なる位置にそれぞれ設けることが好ましい。このように構成すれば、上記のような各浮き上がり防止用金具６を介する左右のレール５０同士の短絡が生じることを防止することができる。   Therefore, when the metal fitting 6 for preventing lifting is made of metal, as shown in FIG. 7 (B), the slit S is formed on the left and right side surfaces of the insulating duct 1 for the hot-air snow melting device in the longitudinal direction of the duct. It is preferable to provide them at different positions. If comprised in this way, it can prevent that the short circuit of the rails 50 on either side via each above-mentioned metal fitting 6 for anti-lifting arises.

一方、本実施形態では、温風式融雪装置用絶縁ダクト１がレール５０に向かう方向（すなわちダクトの短手方向）に位置ずれを生じることを防止するために、図８に示すような短手方向位置ずれ防止金具７が用いられている。本実施形態では、短手方向位置ずれ防止金具７は、温風式融雪装置用絶縁ダクト１の側面部に係合する係合部７ａと、短手方向位置ずれ防止金具７を枕木５１にボルトで螺着する等して取り付けるための取付部７ｂとを有している。そして、図８では図示を省略したが、温風式融雪装置用絶縁ダクト１の反対側の側面にも短手方向位置ずれ防止金具７が取り付けられる。   On the other hand, in the present embodiment, in order to prevent the hot air type snow melting device insulating duct 1 from being displaced in the direction toward the rail 50 (that is, the short direction of the duct), the short side as shown in FIG. A directional misalignment prevention fitting 7 is used. In the present embodiment, the short direction misalignment prevention metal fitting 7 includes the engaging portion 7a that engages with the side surface portion of the insulation duct 1 for the hot air type snow melting device, and the short direction misalignment prevention metal fitting 7 to the sleeper 51. And a mounting portion 7b for mounting by screwing or the like. And although illustration is abbreviate | omitted in FIG. 8, the transversal-direction position shift prevention metal fitting 7 is attached also to the side surface on the opposite side of the insulation duct 1 for hot air type snow melting apparatuses.

このようにして、短手方向位置ずれ防止金具７の係合部７ａが温風式融雪装置用絶縁ダクト１の側面部に係合するように取付部７ｂを枕木５１に取り付けて固定することで、鉄道車両が分岐器を通過する際に振動が生じる等した際に、温風式融雪装置用絶縁ダクト１が短手方向に移動しようとしても短手方向位置ずれ防止金具７により移動が阻止されるため、温風式融雪装置用絶縁ダクト１がその短手方向に移動すること（すなわち短手方向への位置ずれ）を的確に防止することが可能となる。   In this way, by attaching and fixing the attachment portion 7b to the sleeper 51 so that the engagement portion 7a of the short-direction-direction displacement preventing metal fitting 7 engages with the side surface portion of the insulation duct 1 for the hot air type snow melting device. In the event that vibrations occur when the railway vehicle passes through the branching device, even if the insulation duct 1 for the hot air type snow melting device tries to move in the short direction, the movement in the short direction is prevented by the misalignment prevention fitting 7. Therefore, it is possible to accurately prevent the hot-air snow melting device insulating duct 1 from moving in the short direction (that is, positional displacement in the short direction).

また、本実施形態では、温風式融雪装置用絶縁ダクト１がレール５０に沿う方向（すなわちダクトの長手方向）に位置ずれを生じることを防止するために、図９に示すような長手方向位置ずれ防止金具８が用いられている。本実施形態では、長手方向位置ずれ防止金具８は、略Ｌ字状の形状をしており、温風式融雪装置用絶縁ダクト１の長手方向の末端部に当接する当接部８ａと、長手方向位置ずれ防止金具８を枕木５１にボルトで螺着する等して取り付けるための取付部８ｂとを有している。   Further, in this embodiment, the longitudinal position as shown in FIG. 9 is used to prevent the insulation duct 1 for the hot-air snow melting device from being displaced in the direction along the rail 50 (that is, the longitudinal direction of the duct). A slip prevention metal fitting 8 is used. In the present embodiment, the longitudinal-direction misalignment prevention fitting 8 has a substantially L-shape, a contact portion 8a that contacts the longitudinal end portion of the insulation duct 1 for a hot-air snow melting device, There is an attachment portion 8b for attaching the directional displacement prevention metal fitting 8 to the sleeper 51 by screwing it or the like.

そして、図９では図示を省略したが、温風式融雪装置用絶縁ダクト１の反対側の末端部にも同様の長手方向位置ずれ防止金具８が当接するように取り付けられる。また、本実施形態では、図９に示すように、長手方向位置ずれ防止金具８の取付部８ｂは、２つの枕木５１にわたる長さを有しており、２つの枕木５１にそれぞれ固定されるようになっている。   Although not shown in FIG. 9, the same longitudinal-direction misalignment prevention fitting 8 is attached to the opposite end of the hot air type snow melting device insulating duct 1. Further, in the present embodiment, as shown in FIG. 9, the attachment portion 8 b of the longitudinal direction displacement prevention metal fitting 8 has a length extending over the two sleepers 51, and is fixed to the two sleepers 51, respectively. It has become.

このようにして、長手方向位置ずれ防止金具８の当接部８ａが温風式融雪装置用絶縁ダクト１の長手方向の末端部に当接するように取付部８ｂを枕木５１に固定することで、鉄道車両が分岐器を通過する際に振動が生じる等した際に、温風式融雪装置用絶縁ダクト１が長手方向に移動しようとしても長手方向位置ずれ防止金具８により移動が阻止されるため、温風式融雪装置用絶縁ダクト１がその長手方向に移動すること（すなわち長手方向への位置ずれ）を的確に防止することが可能となる。   In this way, by fixing the attachment portion 8b to the sleeper 51 so that the abutting portion 8a of the longitudinal position displacement prevention metal fitting 8 abuts the longitudinal end portion of the insulating duct 1 for the hot air type snow melting device, When the railway vehicle passes through the branching device, when the vibration is generated, the hot air type snow melting device insulating duct 1 is prevented from moving by the longitudinal misalignment prevention fitting 8 even if trying to move in the longitudinal direction. It is possible to accurately prevent the hot air type snow melting device insulating duct 1 from moving in the longitudinal direction (that is, positional displacement in the longitudinal direction).

なお、本実施形態では、上記のように、浮き上がり防止用金具６の取付板６ａを温風式融雪装置用絶縁ダクト１の側面に形成されたスリットＳに挿入して、温風式融雪装置用絶縁ダクト１の浮き上がりを防止する（図７（Ｂ）等参照）。そして、このように構成することで、浮き上がり防止用金具６の取付板６ａとスリットＳとが係合して、温風式融雪装置用絶縁ダクト１が長手方向に移動すること（すなわち長手方向の位置ずれ）を防止する長手方向位置ずれ防止金具８としても機能するようになっている。
また、本実施形態では、図８に示したように、短手方向位置ずれ防止金具７の係合部７ａは、温風式融雪装置用絶縁ダクト１の側面部だけでなくその上面にも係合する形状になっている。そのため、本実施形態に係る短手方向位置ずれ防止金具７は、温風式融雪装置用絶縁ダクト１の浮き上がりを防止する浮き上がり防止用金具６としても機能するようになっている。 In the present embodiment, as described above, the mounting plate 6a of the lifting prevention metal fitting 6 is inserted into the slit S formed on the side surface of the insulation duct 1 for the hot air type snow melting device, so as to be used for the hot air type snow melting device. The insulation duct 1 is prevented from rising (see FIG. 7B, etc.). And by comprising in this way, the mounting plate 6a of the metal fitting 6 for raising prevention, and the slit S engage, and the insulation duct 1 for warm air type snow melting apparatuses moves to a longitudinal direction (namely, longitudinal direction) It also functions as a longitudinal misalignment prevention fitting 8 that prevents misalignment).
Further, in the present embodiment, as shown in FIG. 8, the engaging portion 7a of the short-direction misalignment prevention fitting 7 is not only related to the side surface portion of the insulating duct 1 for the hot air type snow melting device but also to the upper surface thereof. It has a matching shape. For this reason, the lateral direction displacement prevention metal fitting 7 according to the present embodiment also functions as a lifting prevention metal fitting 6 for preventing the hot air type snow melting device insulating duct 1 from floating up.

さらに、図９では、長手方向位置ずれ防止金具８の当接部８ａが、単に温風式融雪装置用絶縁ダクト１の長手方向の末端部に当接するだけの形状とされている場合を示したが、例えば、図８に示した短手方向位置ずれ防止金具７の係合部７ａと同様に、長手方向位置ずれ防止金具８の当接部８ａを、温風式融雪装置用絶縁ダクト１の末端部の上面にも係合する形状に形成すれば、長手方向位置ずれ防止金具８が、温風式融雪装置用絶縁ダクト１の浮き上がりを防止する浮き上がり防止用金具６としても機能するようになる。
このように、各金具に、浮き上がり防止用金具６の機能や短手方向位置ずれ防止金具７の機能、長手方向位置ずれ防止金具８の機能等の種々の機能をもたせるように構成し、温風式融雪装置用絶縁ダクト１の設置場所に合わせて各金具を適切に選定して用いるように構成することが望ましい。 Further, FIG. 9 shows a case where the contact portion 8a of the longitudinal position displacement prevention metal fitting 8 is simply shaped to contact the longitudinal end portion of the insulating duct 1 for the hot air type snow melting device. However, for example, in the same manner as the engaging portion 7a of the lateral direction displacement prevention metal fitting 7 shown in FIG. 8, the contact portion 8a of the longitudinal direction displacement prevention metal fitting 8 is connected to the insulation duct 1 for the hot-air snow melting device. If it is formed in a shape that also engages with the upper surface of the end portion, the longitudinal displacement prevention metal fitting 8 will function as a lifting prevention metal fitting 6 that prevents the insulation duct 1 for the hot-air snow melting device from rising. .
In this way, each metal fitting is configured to have various functions such as the function of the lifting prevention metal fitting 6, the function of the short-direction displacement prevention metal fitting 7, and the function of the longitudinal displacement prevention metal fitting 8. It is desirable that each metal fitting is appropriately selected and used in accordance with the installation location of the insulation duct 1 for a snow melting device.
