Description

本発明は、鉄道車両の軌道としてのレールを接続・電気的絶縁をする部分を構成する接着絶縁レールに係り、特に、脱線時損傷防止接着絶縁レールに関するものである。   The present invention relates to an adhesive insulating rail that constitutes a portion that connects and electrically insulates a rail as a railcar track, and more particularly to an adhesive insulating rail that prevents damage during derailment.

図７は従来の接着絶縁レールの透視上面図、図８は図７のＡ−Ａ線断面図である。
これらの図において、１０１はレール、１０２は継目板、１０３は接着層、１０４は継目板ボルト、１０４Ａは継目板ボルトのヘッド、１０４Ｂは雌ネジが設けられた継目板ボルトの先端部、１０４Ｃはその継目板ボルトの先端部１０４Ｂに螺合されたナット、１０５は継目板端部、１０６はレール形である。 7 is a perspective top view of a conventional adhesive insulating rail, and FIG. 8 is a cross-sectional view taken along line AA of FIG.
In these drawings, 101 is a rail, 102 is a seam plate, 103 is an adhesive layer, 104 is a seam plate bolt, 104A is a head of the seam plate bolt, 104B is a tip of the seam plate bolt provided with a female screw, and 104C is A nut screwed to the tip 104B of the joint plate bolt, 105 a joint plate end, and 106 a rail shape.

このように、従来の接着絶縁レールは、継目板１０２の上部の鍔部１０２Ａの下方で、継目板ボルト１０４の先端部１０４Ｂ及び先端部１０４Ｂに螺合されたナット１０４Ｃが線路幅方向に突出するような形状となっている。また、継目板端部１０５は線路方向に直角になるように形成されている。
なし As described above, in the conventional adhesive insulated rail, the tip 104B of the joint plate bolt 104 and the nut 104C screwed to the tip 104B protrude in the line width direction below the flange 102A at the top of the joint plate 102. It has a shape like this. Further, the joint plate end portion 105 is formed to be perpendicular to the line direction.
None

しかしながら、脱線時に脱線車輪もしくは台車の部材の衝撃により上記のような従来の接着絶縁レールが破損する事態が発生することが想定される。具体的には、まず、図７の矢印ａに示すように、継目板から線路幅方向に突出した継目板ボルト１０４の先端部１０４Ｂ及び先端部１０４Ｂに螺合されたナット１０４Ｃに、脱線した車輪または台車の部材が衝突して、継目板ボルト１０４が引きちぎられて継目板ボルト１０４が破損するといった問題がある。   However, it is assumed that the conventional adhesive insulation rail as described above is damaged due to the impact of the members of the derailing wheel or the carriage during derailment. Specifically, first, as shown by an arrow a in FIG. 7, the wheel 104 derailed to the tip 104B of the joint plate bolt 104 protruding from the joint plate in the line width direction and the nut 104C screwed to the tip 104B. Or there is a problem that the member of the carriage collides, the joint plate bolt 104 is torn off, and the joint plate bolt 104 is damaged.

また、継目板端部１０５は線路方向に直角になるように形成されているので、図７の矢印ｂに示すように、その継目板端部１０５に直に脱線した車輪または台車の部材が衝突して、継目板１０２が継目板ボルト１０４を押すことにより、継目板ボルト１０４が切断されるといった問題がある。
このように、継目板ボルト１０４が折損すると、継目板１０２がレール１０１から分離し、継目板１０２による２本のレールを接続する機能が失われてしまう。 Further, since the joint plate end portion 105 is formed so as to be perpendicular to the track direction, as shown by an arrow b in FIG. 7, a wheel or carriage member that has been derailed directly collides with the joint plate end portion 105. Then, there is a problem that the joint plate bolt 104 is cut when the joint plate 102 pushes the joint plate bolt 104.
Thus, when the joint plate bolt 104 is broken, the joint plate 102 is separated from the rail 101, and the function of connecting the two rails by the joint plate 102 is lost.

本発明は、上記問題点を解決するために、簡便な構造で、継目板ボルトの破損を防止することができる脱線時損傷防止接着絶縁レールを提供することを目的とする。   In order to solve the above-described problems, an object of the present invention is to provide a derailment damage preventing adhesive insulating rail capable of preventing breakage of a joint plate bolt with a simple structure.

本発明は、上記目的を達成するために、
〔１〕レールの継目板と、接着層を介して前記レールの継目板をレールに固定する継目板ボルトとを具備する接着絶縁レールにおいて、前記レールの継目板上部の鍔部の幅を継目板ボルトの長さより長くして前記継目板ボルトを外部からの車輪や台車の部材の衝突から保護することを特徴とする。 In order to achieve the above object, the present invention provides
[1] An adhesively insulated rail comprising a rail joint plate and a joint plate bolt for fixing the rail joint plate to the rail via an adhesive layer, wherein the width of the flange portion above the rail joint plate is defined as the joint plate The length of the bolt is longer than the length of the bolt to protect the joint plate bolt from the collision of the wheel or carriage member from the outside.

〔２〕上記〔１〕記載の脱線時損傷防止接着絶縁レールにおいて、前記レールの継目板端部に線路方向に漸次広がる側面テーパを形成することを特徴とする。   [2] In the derailment damage-preventing adhesive insulating rail according to [1], a side taper that gradually spreads in a line direction is formed at a joint plate end portion of the rail.

本発明によれば、次のような効果を奏することができる。
車輪が脱線した場合、継目板ボルトに直接脱線した車輪が当たらないようにして、継目板ボルトの破損を防止することができる。 According to the present invention, the following effects can be achieved.
If the vehicle wheel has derailed, so as not be exposed to wheels derailed directly the seam plate bolt, it is possible to prevent damage to the seam plate bolts.

本発明の脱線時損傷防止接着絶縁レールは、レールの継目板と、接着層を介して前記レールの継目板をレールに固定する継目板ボルトとを具備する接着絶縁レールにおいて、前記レールの継目板上部の鍔部をレールの幅方向に広げた断面形状にして前記継目板ボルトを外部からの車輪や台車の部材の衝突から保護する。   A derailed damage-preventing adhesive insulated rail according to the present invention is an adhesive insulated rail comprising a rail joint plate and a joint plate bolt for fixing the rail joint plate to the rail via an adhesive layer. The upper flange is formed into a cross-sectional shape that is widened in the width direction of the rail to protect the joint plate bolts from collisions of wheels and carriage members from the outside.

以下、本発明の実施の形態について詳細に説明する。
図１は本発明の実施例を示す脱線時損傷防止接着絶縁レールの上面図、図２は図１のＢ−Ｂ線断面図である。
これらの図において、１はレール、２は継目板、２Ａは継目板上部の鍔部、２Ｂは継目板腹部、３は接着層、４は継目板ボルト、４Ａは継目板ボルトのヘッド、４Ｂは雌ネジが設けられた継目板ボルトの先端部、４Ｃはその継目板ボルトの先端部４Ｂに螺合されたナット、５は継目板端部、６はその継目板端部５に形成された線路方向に傾斜した側面のテーパ部、７はレール形である。 Hereinafter, embodiments of the present invention will be described in detail.
Figure 1 is a top view, FIG. 2 is sectional view taken along line B-B of FIG. 1 derailment Damage prevention adhesive insulating rail showing the actual施例of the present invention.
In these drawings, 1 is a rail, 2 is a seam plate, 2A is a collar part at the top of the seam plate, 2B is a seam plate abdomen, 3 is an adhesive layer, 4 is a seam plate bolt, 4A is a head of the seam plate bolt, 4B is The tip of the joint plate bolt provided with the female screw, 4C is a nut screwed into the tip 4B of the joint plate bolt, 5 is the joint plate end, and 6 is the line formed at the joint plate end 5. The taper part 7 of the side surface inclined in the direction is a rail shape.

この実施例では、図２に示すように、レール１に対して接着層３を介して継目板ボルト４によって固定される継目板２の上部の鍔部２Ａの幅を広く、継目板腹部２Ｂの幅を狭く、さらに継目板ボルト４の長さを短くして継目板ボルト４を外部からの車輪もしくは台車の部材の衝突に対して保護するような断面形状とする。なお、ここでは、継目板２の上部の鍔部２Ａの幅を広く、継目板腹部２Ｂの幅を狭く、さらに継目板ボルト４の長さを短くするように構成したが、これに代えて、単純に継目板２の上部の鍔部２Ａの幅を広げる。または、部分的に継目板腹部２Ｂを削って短めの継目板ボルトが継目板２の上部の鍔部２Ａに隠れるようにする、つまり、継目板ボルトが継目板の上部の鍔部により上からみて隠れるようにすればよい。   In this embodiment, as shown in FIG. 2, the width of the upper flange portion 2A of the joint plate 2 fixed to the rail 1 by the joint plate bolt 4 via the adhesive layer 3 is widened, and the joint plate abdominal portion 2B. The cross-sectional shape is such that the width is narrow and the length of the joint plate bolt 4 is shortened so that the joint plate bolt 4 is protected from the collision of the wheel or carriage member from the outside. Here, the width of the flange 2A at the top of the joint plate 2 is wide, the width of the joint plate abdomen 2B is narrow, and the length of the joint plate bolt 4 is shortened, but instead, Simply widen the width of the collar 2 </ b> A at the top of the joint plate 2. Alternatively, the seam plate abdomen 2B is partially shaved so that the shorter seam plate bolt is hidden in the flange 2A at the top of the seam plate 2, that is, the seam plate bolt is viewed from above by the collar at the top of the seam plate. Just hide it.

また、この実施例では、図１に示すように、継目板端部５に線路方向に漸次広がるように傾斜した側面のテーパ部６を形成するようにしたので、車輪が脱線した場合、車輪もしくは台車の部材が継目板端部５に衝突しても継目板２への衝撃を和らげることができる。従来のように、継目板の先端部が線路方向に直角である場合には、車輪が脱線した場合、車輪もしくは台車の部材が継目板の端部にまともに衝突するため、継目板への衝撃が大きく、継目板ボルトの破損を招来することになる。   Further, in this embodiment, as shown in FIG. 1, since the tapered portion 6 of the side surface inclined so as to gradually spread in the line direction is formed in the joint plate end portion 5, when the wheel is derailed, the wheel or Even if the member of the carriage collides with the joint plate end portion 5, the impact on the joint plate 2 can be reduced. When the tip of the seam plate is perpendicular to the track direction as in the past, if the wheel is derailed, the wheel or carriage member will collide with the end of the seam plate. Is large, leading to breakage of the joint plate bolt.

このように構成したので、（１）車輪が脱線した場合、継目板ボルトに直接脱線した車輪が当たらないようにして、継目板ボルトの破損を防止することができる。（２）車輪が脱線した場合、車輪もしくは台車の部材が継目板の端部にあたるときの衝撃を低減させることができる。
図３は本発明の実施例の変形例を示す図である。 Since it comprised in this way, (1) When a wheel derails, it can prevent the wheel which carried out the derailment directly from hitting a joint board bolt, and can prevent a damage to a joint board bolt. (2) When a wheel derails, it is possible to reduce an impact when a wheel or carriage member hits an end of a joint plate.
Figure 3 is a diagram showing a modification of the real施例of the present invention.

この例では、継目板端部に形成された線路方向に漸次広がるように傾斜した側面のテーパ部８，９を継目板端部の両側に形成するようにした。
このように形成することにより、当該レールは何れの方向からの鉄道車両の走行にも対応させることができる。また、曲線部において、一本の曲線用接着絶縁レールを内軌と外軌の両方に使用することができる。 In this example, the tapered portions 8 and 9 on the side surfaces inclined so as to gradually spread in the line direction formed at the end portion of the joint plate are formed on both sides of the end portion of the joint plate.
By forming in this way, the rail can be adapted to travel of the railway vehicle from any direction. Further, in the curved portion, one curved adhesive insulating rail can be used for both the inner track and the outer track.

図４は本発明の参考例を示す緩衝部材を有する脱線時損傷防止接着絶縁レールの上面図、図５はその脱線時損傷防止接着絶縁レールの前方に配置される緩衝部材の側面図、図６はその緩衝部材を有する接着絶縁レールの断面図であり、図６（ａ）は図４のＣ−Ｃ線断面図、図６（ｂ）は図４のＤ−Ｄ線断面図である。
これらの図において、１１はレール、１２は継目板、１２Ａは継目板上部の鍔部、１２Ｂは継目板腹部、１３は接着層、１４は継目板ボルト、１４Ａは継目板ボルトのヘッド、１４Ｂは雌ネジが設けられた継目板ボルトの先端部、１４Ｃはその継目板ボルトの先端部１４Ｂに螺合されたナット、１５は継目板端部、１６はその継目板端部１５の前方に、継目板１２とは一定間隔をあけて配置される緩衝部材、１８は緩衝部材１６の先端部、１９はその緩衝部材１６の先端部１８に形成される側面テーパ部、２０は緩衝部材１６の線路方向に形成される長穴、２１は緩衝部材１６の固定ボルトであり、前記長穴２０の後端に螺合するようにされている。 4 is a top view of a derailed damage preventing adhesive insulating rail having a buffer member showing a reference example of the present invention, FIG. 5 is a side view of the buffer member disposed in front of the derailing damage preventing adhesive insulating rail, FIG. FIG. 6A is a cross-sectional view of the adhesive insulating rail having the buffer member, FIG. 6A is a cross-sectional view taken along the line CC in FIG. 4, and FIG. 6B is a cross-sectional view taken along the line DD in FIG.
In these drawings, 11 is a rail, 12 is a seam plate, 12A is a collar portion at the top of the seam plate, 12B is an abdomen portion of the seam plate, 13 is an adhesive layer, 14 is a seam plate bolt, 14A is a head of the seam plate bolt, 14B is 14C is a nut screwed to the tip 14B of the joint plate bolt, 15 is a joint plate end, and 16 is a joint in front of the joint plate end 15. The buffer member is disposed at a predetermined distance from the plate 12, 18 is the tip of the buffer member 16, 19 is a side taper formed at the tip 18 of the buffer member 16, and 20 is the line direction of the buffer member 16. A long hole 21 formed in the first hole 21 is a fixing bolt for the buffer member 16 and is screwed into the rear end of the long hole 20.

そこで、脱線した車輪もしくは台車の部材が、緩衝部材１６に衝突する場合、緩衝部材１６の先端部１８に形成される側面テーパ部１９に衝突するために衝撃が和らげられるとともに、緩衝部材１６の線路方向に形成される長穴２０を介して、緩衝部材１６を線路方向にスライドできるので、スライド時の摩擦抵抗により線路方向の荷重が緩和され、さらに衝撃を吸収できる。なお、上記実施例と同様に、本参考例でも継目板上部の鍔部１２Ａの幅を広く、継目板腹部１２Ｂの幅を狭く、さらに継目板ボルト１４の長さを短くし、継目板上部の鍔部１２Ａで継目板ボルト１４を保護できるような形状になっている。また、緩衝部材１６の固定ボルト２１も、緩衝部材１６の上部の鍔部１６Ａにより保護されるようになっている。 Therefore, when the derailed wheel or carriage member collides with the buffer member 16, the impact is mitigated because it collides with the side taper portion 19 formed at the front end portion 18 of the buffer member 16, and the line of the buffer member 16 is also reduced. Since the buffer member 16 can be slid in the line direction through the long hole 20 formed in the direction, the load in the line direction is relieved by the frictional resistance at the time of sliding, and the impact can be absorbed. Similarly to the above embodiment, the width of the seam plate top of the flange portion 12A in this reference example, narrowing the width of the seam plate abdomen 12B, and further reduce the length of the seam plate bolts 14, joint plate of the upper The shape is such that the joint plate bolt 14 can be protected by the flange portion 12A. Further, the fixing bolt 21 of the buffer member 16 is also protected by the flange portion 16 </ b> A at the top of the buffer member 16.

なお、図４に示した緩衝部材１６は従来の接着絶縁レールの前方に取り付けることも可能であり、脱線した車輪もしくは台車の部材が、緩衝部材１６に衝突する場合、衝撃を吸収でき、接着絶縁レールの破損防止の効果を期待できる。
また、本発明は上記実施例に限定されるものではなく、本発明の趣旨に基づき種々の変形が可能であり、これらを本発明の範囲から排除するものではない。 The buffer member 16 shown in FIG. 4 can also be attached in front of a conventional adhesive insulation rail. When a derailed wheel or carriage member collides with the buffer member 16, the shock can be absorbed and the adhesive insulation can be obtained. Expected to prevent rail damage.
Further, the present invention is not limited to the above-described embodiments, and various modifications can be made based on the spirit of the present invention, and these are not excluded from the scope of the present invention.

本発明の接着絶縁レールは、地震による車輪の脱線時にも鉄道車両の軌道の破損を防止し、被害を軽減できる脱線時損傷防止接着絶縁レールとして利用可能である。   The adhesive insulated rail of the present invention can be used as a derailed damage preventing adhesive insulated rail that can prevent damage to the railcar track even when the wheel is derailed due to an earthquake.
