Description

本発明は、車両の進路を選択する分岐器などに設置されてレールに積もった雪などを溶かす融雪器に関するものである。 The present invention relates to a snow melting device that is installed in a branching device for selecting a course of a vehicle and melts snow or the like that has accumulated on a rail.

はじめに、融雪器が設置される分岐器の一般的な構成を説明する。分岐器のポイント部を担う転てつ器として、例えば下記非特許文献１に記載された転てつ装置がある（図１６参照）。この転てつ装置は転換装置と鎖錠装置とから構成され、電気転てつ機１０１によって稼働する。ここで転換装置は、固定された基本レール１０９に対してトングレール１１０を密着させ、または離反させるものであり、一方、鎖錠装置はトングレール１１０と基本レール１０９との密着状態を保持するものである。 First, a general configuration of a branching device in which a snow melting device is installed will be described. For example, there is a switch device described in Non-Patent Document 1 below as a switch device that bears the point portion of the switch (see FIG. 16). This switch device is composed of a conversion device and a lock device, and is operated by an electric switch 101. Here, the conversion device makes the Tongler 110 come into close contact with or separate from the fixed basic rail 109, while the locking device keeps the contact state between the Tongrel 110 and the basic rail 109. It is.

電気転てつ機１０１は、軌間外（一対の基本レール１０９間の外側）に延びた二本の枕木１００上に設置されている。この電気転てつ機１０１は、駆動源である交流モータ１０８からの駆動力を、摩擦クラッチ、減速歯車及び転換ローラ付転換歯車（それぞれ図示せず）の順に伝導し、転換ローラにより動作かん１０２を移動させる。 The electric switch 101 is installed on two sleepers 100 extending outside the gauge (outside between the pair of basic rails 109). The electric switch 101 transmits the driving force from the AC motor 108 as a driving source in the order of a friction clutch, a reduction gear, and a conversion gear with a conversion roller (each not shown), and is operated by the conversion roller 102. Move.

動作かん１０２は、この動作かん１０２に接続されたカム（図示せず）が転換ローラによって移動することで、基本レール１０９と直交する方向に直線運動する。電気転てつ機１０１は、この動作かん１０２に接続されたスイッチアジャスタ１０３、スイッチアジャスタ１０３の先端側に接続された転てつ棒１０４を介してトングレール１１０を転換し、その転換されたトングレール１１０の先端が正常な位置にあるか否かがフロントロッド１０５、接続かん１０６及び鎖錠かん１０７によって照査される。トングレール１１０の先端が正常な位置にあれば、動作かん１０２及び鎖錠かん１０７がカムバー（ロックピース）（図示せず）で鎖錠される。 The motion can 102 moves linearly in a direction orthogonal to the basic rail 109 when a cam (not shown) connected to the motion can 102 is moved by a conversion roller. The electric switch 101 converts the tongler 110 through the switch adjuster 103 connected to the operation unit 102 and the switch rod 104 connected to the tip end of the switch adjuster 103, and the converted tongue Whether the front end of the rail 110 is in a normal position is checked by the front rod 105, the connecting rod 106 and the locking rod 107. If the tip of the tongue rail 110 is in a normal position, the operation lever 102 and the locking lever 107 are locked with a cam bar (lock piece) (not shown).

融雪器は、上記したような分岐器に設置され、レールに積もった雪や、レールに凍りついた雨水などを熱で融解させるものである。融雪器は、成形の簡便さからアルミニウム製が多く、この場合、成形時に電気ヒーターが内蔵される。このような融雪器が、例えば、下記特許文献１および特許文献２に記載されている。 The snow melter is installed in a branching device as described above, and melts snow accumulated on the rail or rainwater frozen on the rail with heat. Snow melters are often made of aluminum for ease of molding, and in this case, an electric heater is built in during molding. Such snow melters are described in, for example, Patent Document 1 and Patent Document 2 below.

特許文献１によれば、融雪器は、内側がくり抜かれた床板の中に取り付けられ、電気ヒーターによって発熱することで、床板を介して基本レールが熱せられる。一方、特許文献２によれば、融雪器は、基本レールの腹部側面に取り付けられ、基本レールが直接熱せられる。 According to Patent Document 1, the snow melter is mounted in a floor plate hollowed out inside, and the basic rail is heated through the floor plate by generating heat with an electric heater. On the other hand, according to Patent Document 2, the snow melter is attached to the abdomen side surface of the basic rail, and the basic rail is directly heated.

平成１７年６月２８日、社団法人日本鉄道電気技術協会発行、「鉄道技術者のための電気概論信号シリーズ４転てつ装置」、第７刷、第１、３８〜４７頁June 28, 2005, issued by Japan Railway Electrical Engineering Association, "Introduction to Electricity for Railway Engineers Signal Series 4 Switching Device", 7th print, pages 1, 38-47

特許文献１に記載された融雪器の場合、上記したとおり内側がくり抜かれた床板の中に取り付けられて電気ヒーターによって発熱するため、熱で木製の枕木が焦げる場合や、合成樹脂製の枕木が融解する場合がある。また、経年劣化により錆びつくと交換ができなくなる場合がある。一方、特許文献２に記載された融雪器の場合、上記したとおり基本レールの腹部側面に取り付けられているため、熱移動において分散され、特に、基本レールの腹部側面よりも下方側である底部に熱が伝わり難い。更に、一般的な融雪器はアルミニウム製であり、熱伝導率が融雪器とレールとで異なるため、熱伝導の効率が悪い。したがって、従来の融雪器は、熱伝導の効率を上げるために、高い電力や緻密な制御を要し、これらを実現するために高額の設備費用が必要である。 In the case of the snow melting device described in Patent Document 1, it is attached to the floor plate that has been hollowed out as described above, and heat is generated by an electric heater. Therefore, when a wooden sleeper is burned by heat, or a synthetic resin sleeper is used. May melt. In addition, when rusted due to aging, it may not be possible to replace. On the other hand, in the case of the snow melter described in Patent Document 2, since it is attached to the abdomen side surface of the basic rail as described above, it is dispersed in heat transfer, and in particular, to the bottom part that is below the abdomen side surface of the basic rail. It is difficult to transmit heat. Furthermore, a general snow melter is made of aluminum, and since the thermal conductivity is different between the snow melter and the rail, the efficiency of heat conduction is poor. Therefore, the conventional snow melter requires high electric power and precise control in order to increase the efficiency of heat conduction, and high equipment costs are required to realize these.

本発明は、上記の実情に鑑みて提案されたものである。すなわち、熱伝導の効率がよく、設備費用を低減することができる融雪器の提供を目的とする。 The present invention has been proposed in view of the above circumstances. That is, an object of the present invention is to provide a snow melting device that has good heat conduction efficiency and can reduce equipment costs.

上記目的を達成するために、本発明に係る融雪器は、枕木の上に敷かれたレールに取り付けられた融雪器において、発熱部材が収納されて前記レールと同一の素材で形成された発熱部受け部材が、前記枕木同士の間に配置されると共に前記レールの底部の底面側に取り付けられた、ことを特徴とする。 In order to achieve the above object, a snow melting device according to the present invention is a snow melting device attached to a rail laid on a sleeper, wherein a heat generating member is housed and formed of the same material as the rail. A receiving member is disposed between the sleepers and attached to the bottom surface of the bottom of the rail.

本発明に係る融雪器は、前記レールの底部の底面側に向けて前記発熱部材が層状に形成され、車両の進路を選択する分岐器の転てつ装置に接続されて前記レールを転換するレール転換部材と前記枕木との間に前記発熱部受け部材が配置された、ことを特徴とする。 In the snow melting device according to the present invention, the heating member is formed in layers toward the bottom surface side of the bottom portion of the rail, and the rail is connected to the switch device of the branching device that selects the course of the vehicle to change the rail. The heat generating portion receiving member is disposed between the conversion member and the sleepers.

本発明に係る融雪器は、前記発熱部受け部材が分割される、ことを特徴とする。 The snow melter according to the present invention is characterized in that the heat generating portion receiving member is divided.

本発明に係る融雪器は、前記発熱部受け部材の大きさが前記レールの底部の幅に揃えられた、ことを特徴とする。 The snow melter according to the present invention is characterized in that the size of the heat generating portion receiving member is aligned with the width of the bottom portion of the rail.

本発明に係る融雪器は、前記レールの底部の軌間内側の縁部と、前記レールの底部の軌間外側の上面側とを挟む取付部が形成された、ことを特徴とする。 The snow melter according to the present invention is characterized in that an attachment portion is formed that sandwiches the inner edge of the rail at the bottom of the rail and the upper surface of the rail at the bottom of the rail.

本発明に係る融雪器は上記した構成である。この構成により、融雪器の熱伝導率がレールと一致し、また、レールの底部の底面側から上方側に向けてレールが加熱される。したがって、熱伝導の効率をよくすることができ、設備費用を低減することができる。 The snow melter according to the present invention has the above-described configuration. With this configuration, the thermal conductivity of the snow melter matches that of the rail, and the rail is heated upward from the bottom surface side of the bottom portion of the rail. Therefore, the efficiency of heat conduction can be improved, and the equipment cost can be reduced.

本発明に係る融雪器は、レールの底部の底面側に向けて発熱部材が層状に形成され、車両の進路を選択する分岐器の転てつ装置に接続されてレールを転換するレール転換部材と枕木との間に発熱部受け部材が配置されている。この構成により、レールの底部の底面側に向けて発熱部材が層状に形成された分、融雪器は発熱部受け部材が底面側に張り出される。一方、底面側に張り出された分、融雪器は発熱部受け部材の大きさがレールの長さ方向において縮小される。したがって、枕木同士の間の空間がレール転換部材によって狭められている場合であっても、レール転換部材と枕木との間に融雪器を配置することができる。また、この場合であっても、レールの底部の底面側に向けて発熱部材が層状に形成されているため、発熱部材において雪や氷の融解に必要な電力を供給するための表面積を補うことができる。 A snow melting device according to the present invention includes a rail conversion member that forms a layer of heat generation members toward the bottom surface of the bottom of the rail, and is connected to a switch device of a branching device that selects the course of the vehicle to convert the rail. A heating part receiving member is disposed between the sleepers. With this configuration, the heat melting member is formed in layers toward the bottom side of the bottom portion of the rail, so that the heat melting member receiving member projects to the bottom side. On the other hand, the size of the heat generating member receiving member of the snow melter is reduced in the length direction of the rail by the amount projected to the bottom side. Therefore, even if it is a case where the space between sleepers is narrowed by the rail switching member, a snow melting machine can be arrange | positioned between a rail switching member and a sleeper. Even in this case, since the heat generating member is formed in layers toward the bottom side of the bottom of the rail, the heat generating member supplements the surface area for supplying electric power necessary for melting snow and ice. Can do.

本発明に係る融雪器は、発熱部受け部材が分割される。この構成により、発熱部受け部材が分割されて融雪器が分解される。したがって、アルミニウムによる成形を必要としないことから、溶解したアルミニウムの熱で発熱部材が損傷することがなく、歩留まり率を向上させることができる。また、保守作業時に、発熱部受け部材を分割して発熱部材を点検・交換することができる。 In the snow melter according to the present invention, the heat generating portion receiving member is divided. With this configuration, the heat generating portion receiving member is divided and the snow melting device is disassembled. Therefore, since molding with aluminum is not required, the heat generating member is not damaged by the heat of the dissolved aluminum, and the yield rate can be improved. Further, at the time of maintenance work, the heat generating member receiving member can be divided and the heat generating member can be inspected and replaced.

本発明に係る融雪器は、発熱部受け部材の大きさがレールの底部の幅に揃えられている。この構成により、熱伝導の効率をよくすることができ、設備費用を低減することができる。 In the snow melter according to the present invention, the size of the heat generating portion receiving member is aligned with the width of the bottom portion of the rail. With this configuration, the efficiency of heat conduction can be improved, and the equipment cost can be reduced.

本発明に係る融雪器は、レールの底部の軌間内側の縁部と、レールの底部の軌間外側の上面側とを挟む取付部が形成されている。この構成により、レールに対する融雪器の取付状態を堅固にすることができる。 In the snow melting device according to the present invention, an attachment portion is formed that sandwiches the inner edge of the rail at the bottom of the rail and the upper surface of the rail at the outer side of the rail. With this configuration, the snow melter can be firmly attached to the rail.

次に、第一実施形態に係る融雪器１０の効果を説明する。 Next, the effect of the snow melter 10 according to the first embodiment will be described.

上記したとおり、第一実施形態に係る融雪器１０によれば、発熱部受け部材１６は基本レール１０９と同一の素材であり、例えば鉄製である。この構成により、融雪器１０の熱伝導率が基本レール１０９と一致し、また、基本レール１０９の底部１１１の底面側から上方側に向けて基本レール１０９が高さ方向に全体が加熱される。したがって、熱伝導の効率をよくすることができ、特に、基本レール１０９とトングレール１１０との間の軌間内側の雪や氷を効果的に融雪することができる。また、熱伝導の効率がよいため、設備費用を低減することができる。 As described above, according to the snow melter 10 according to the first embodiment, the heat generating portion receiving member 16 is the same material as the basic rail 109, and is made of, for example, iron.

Therefore, the heat generating member receiving member 16 can be divided and the heat generating member 12 can be inspected and replaced during maintenance work. Moreover, since it is an assembly type, it does not require molding with aluminum, so that the heat generating member is not damaged by the heat of dissolved aluminum, and the yield rate can be improved.

第一実施形態に係る融雪器１０によれば、発熱部受け部材１６は、大きさが基本レール１０９の底部１１１の幅に揃えられている。この構成により、熱伝導の効率をよくすることができ、設備費用を低減することができる。 According to the snow melter 10 according to the first embodiment, the heat generating portion receiving member 16 has the same size as the width of the bottom portion 111 of the basic rail 109. With this configuration, the efficiency of heat conduction can be improved, and the equipment cost can be reduced.

図８に示されているとおり、取付構造３０は、本体受け部材１９の外方側支持部５０、および、端部側受け部材２１の内方側支持部４９から構成されている。取付構造３０は、内方側支持部４９が基本レール１０９の底部１１１の軌間内側の縁部に係止し、基本レール１０９の底部１１１の底面側に放熱部材４１（上層側受け部材４７）を接触させた状態で、外方側支持部５０が基本レール１０９の底部１１１の軌間外側の上面側に係合し、外方側支持部５０に取り付けられたボルト２を介して底部１１１に固定される。 As shown in FIG. 8, the attachment structure 30 includes an outer side support portion 50 of the main body receiving member 19 and an inner side support portion 49 of the end side receiving member 21. In the mounting structure 30, the inner support portion 49 is locked to the inner edge of the bottom 111 of the basic rail 109, and the heat radiation member 41 (upper layer receiving member 47) is placed on the bottom surface of the bottom 111 of the basic rail 109. In the state of contact, the outer side support portion 50 engages with the upper surface side outside the gauge of the bottom portion 111 of the basic rail 109 and is fixed to the bottom portion 111 via the bolt 2 attached to the outer side support portion 50. The

なお、引出口部材２７は第一実施形態と同じである（図１５参照）。 The outlet member 27 is the same as that in the first embodiment (see FIG. 15).

以上のとおり、第二実施形態に係る融雪器４０が構成されている。 As described above, the snow melter 40 according to the second embodiment is configured.

次に、第二実施形態に係る融雪器４０の効果を説明する。なお、以下のでは、第一実施形態と異なる効果についての説明がされ、同じ効果についての説明が省略されている。 Next, the effect of the snow melting device 40 according to the second embodiment will be described. In the following, effects different from those of the first embodiment are described, and descriptions of the same effects are omitted.

上記したとおり、第二実施形態に係る融雪器４０によれば、図８および図１４に示されているとおり、発熱部材４２は基本レール１０９の底部１１１の底面側に向けて、上層側発熱部１４と下層側発熱部１５とが層状に形成されている。上層側発熱部１４は、基本レール１０９の底部１１１に沿って同一平面上でＵ字状に形成され、内方側で折り返されて下層側発熱部１５に連接されている。下層側発熱部１５は直線状に形成され、外方側（正面側）で基本レール１０９の高さ方向の下方に向けて屈曲し、端子４３が形成されている。この構成により、基本レール１０９の底部１１１の底面側に向けて発熱部材４２が層状に形成された分、融雪器４０は発熱部受け部材４６が底面側に張り出される。一方、底面側に張り出された分、融雪器４０は発熱部受け部材４６の大きさが側方（基本レール１０９の長さ方向）において縮小される。したがって、枕木１００同士の間の空間が、レール転換部材としての接続かん１０６やスイッチアジャスタ１０３などによって狭められている場合であっても、レール転換部材と枕木１００との間に融雪器４０を配置することができる（図１６参照）。また、この場合であっても、基本レール１０９の底部１１１の底面側に向けて発熱部材４２が層状に形成されているため、発熱部材４２において雪や氷の融解に必要な電力を供給するための表面積を補うことができる。 As described above, according to the snow melter 40 according to the second embodiment, as shown in FIGS. 8 and 14, the heat generating member 42 is directed toward the bottom surface of the bottom 111 of the basic rail 109, and the upper layer side heat generating portion. 14 and the lower layer side heat generating part 15 are formed in layers. The upper layer side heat generating portion 14 is formed in a U shape on the same plane along the bottom portion 111 of the basic rail 109, is folded back on the inner side, and is connected to the lower layer side heat generating portion 15. The lower layer side heat generating portion 15 is formed in a straight line, and is bent toward the lower side in the height direction of the basic rail 109 on the outer side (front side) to form a terminal 43. With this configuration, the heat generating member 42 is formed so that the heat generating member 42 is formed in layers toward the bottom surface side of the bottom 111 of the basic rail 109, and the heat generating member receiving member 46 is projected to the bottom surface side. On the other hand, the size of the heat generating member receiving member 46 is reduced in the lateral direction (the length direction of the basic rail 109) in the snow melting device 40 as much as it projects to the bottom surface side. Therefore, even if the space between the sleepers 100 is narrowed by the connecting can 106 or the switch adjuster 103 as a rail change member, the snow melting device 40 is disposed between the rail change member and the sleeper 100. (See FIG. 16). Even in this case, since the heat generating member 42 is formed in layers toward the bottom surface of the bottom 111 of the basic rail 109, the heat generating member 42 supplies power necessary for melting snow and ice. Can compensate for the surface area.

その他の効果は第一実施形態に係る融雪器１０と同じである。 Other effects are the same as those of the snow melter 10 according to the first embodiment.

以上、本発明の実施形態を詳述したが、本発明は上記実施形態に限定されるものではない。そして本発明は、特許請求の範囲に記載された事項を逸脱することがなければ、種々の設計変更を行うことが可能である。 As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to the said embodiment. The present invention can be modified in various ways without departing from the scope of the claims.
