本発明は、鉄道におけるレールに座屈が発生することを防止するための保安装置に関する。  The present invention relates to a safety device for preventing buckling of a rail in a railway.

鉄道における線路は直線状に設けることが好ましいとされているが、曲線状の線路で滑らかに接続されていることも多い。このような曲線状の線路を走行する列車には遠心力が働いて、車両を曲線の外方に向かって倒そうとする力となって作用するほか、走行する車両の荷重による振動も加わるので、軌道の変形や位置ずれなどが発生することは避けられない。そこで線路を確実に支持し固定するためのまくらぎや道床などの構造にも、強度や経済性の観点からの改良が進められ、まくらぎ等も鋼線強化コンクリート製のものが、汎用されるに至っている。  The railroad tracks are preferably provided in a straight line, but are often smoothly connected by a curved track. Centrifugal force acts on a train traveling on such a curved track, acting as a force that tries to tilt the vehicle toward the outside of the curve, and vibration due to the load of the traveling vehicle is also added. It is inevitable that the trajectory is deformed or displaced. Therefore, the structure of sleepers and roadbeds to securely support and fix the track has been improved from the viewpoint of strength and economy, and sleepers made of steel wire reinforced concrete are widely used.

しかし、線路の保守作業に関しては機械化などが進められているものの、人力による保守作業の負荷は大幅には改善されておらず、特に夏期には軌道温度の上昇による線路の膨張で座屈が発生すると、信号トラブルや脱線事故などに繋がる恐れもあって、保線作業員への負荷が増大する傾向にあるので、保線作業の合理化が強く求められ、更にこれに加えて事故発生の予防のための設備の改良にも、機能や耐久性と共に経済性も重視されるようになっている。  However, although the mechanization of track maintenance work has been promoted, the load of maintenance work by human power has not been improved significantly, and buckling occurs due to the expansion of the track due to the rise of track temperature, especially in summer. Then, it may lead to signal troubles and derailment accidents, and the load on track maintenance workers tends to increase, so rationalization of track maintenance work is strongly required, and in addition to this, prevention of accident occurrence Improvements in equipment are also focused on economics as well as function and durability.

そこで本発明は、鉄道における線路の変形や座屈の発生を防止すると同時に、設備取付や補修の作業効率を大幅に改善して、安全で保守が容易な線路構造を迅速に構築することができ、且つ保線作業の負荷を軽くして、保守の作業労力と経費との大幅な節約を図ることができる、レール座屈防止用保安装置を提供することを目的としたものである。  Therefore, the present invention can prevent the occurrence of rail deformation and buckling in a railway, and at the same time, can greatly improve the work efficiency of equipment installation and repair, and can quickly build a safe and easy-to-maintain track structure.

The half portion S1 and the portion covered with the member designated byreference numeral 2 is the upper half S2 of the side end portion of the same sleeper S, and is covered by thereference numeral 1 member and thereference numeral 2 member. The combined portions are referred to as a side end S0.

上記の側端部下半固定部材１の構造を、図２に基づいて詳細に説明するが、図２における(a)は上面図、(b)は正面図、(c)は底面図、(d)は背面図、(e)は(d)の切断位置における立断面図である。
これらの図面において、１aは側端部下半固定部材１の底壁であるが、その底壁の上面には鋭角な稜線を有する凸条が設けてあり、まくらぎＳの側端部Ｓ0の底面が滑ることなく載荷できるようになっている。そして、上記の底壁１aを囲む位置には、まくらぎＳの側端部Ｓ1の端面前に空隙を残すように端面を覆う下前壁１bを設けると共に、下前壁１bの左端部分と、中央位置の上端部分及び下端部分と、右端部分とに、まくらぎＳの側端部Ｓ1の端面を支える空隙維持突起１e、１f、１g、１hを設けたほか、まくらぎＳの側端部Ｓ1の端面と下前壁１bとの空隙を観察できる１対の窓孔１jが設けてあり、更にまくらぎＳの側端部の下半部分Ｓ1の左側面と右側面とを、それぞれ適切な位置に導くための下左壁１cと下右壁１dとが設けてあるほか、１対の杭板挿通孔１k、１kが形成されている。The structure of the side end lowerhalf fixing member 1 will be described in detail with reference to FIG. 2. In FIG. 2, (a) is a top view, (b) is a front view, (c) is a bottom view, (d ) Is a rear view, and (e) is an elevational sectional view at the cutting position of (d).
In these drawings,reference numeral 1a denotes a bottom wall of the side end lowerhalf fixing member 1. On the upper surface of the bottom wall, a convex line having an acute ridge line is provided, and the bottom surface of the side end S0 of the sleeper S is provided. Can be loaded without slipping. And in the position surrounding saidbottom wall 1a, while providing thelower front wall 1b which covers an end surface so that a space | gap may be left in front of the end surface of the side edge part S1 of the sleeper S, the left end part of thelower front wall 1b, In addition to providinggap maintaining protrusions 1e, 1f, 1g, and 1h for supporting the end surface of the side end S1 of the sleeper S at the upper and lower end portions and the right end portion of the center position, the side end S1 of the sleeper S Are provided with a pair ofwindow holes 1j through which the gap between the end face and thelower front wall 1b can be observed, and the left and right sides of the lower half S1 of the side end of the sleeper S are positioned at appropriate positions. In addition to the lowerleft wall 1c and the lowerright wall 1d for guiding to the center, a pair of pileplate insertion holes 1k, 1k are formed.

更に、まくらぎＳの側端部の上半部分Ｓ2を覆う側端部上半固定部材２の構造を、図３に基づいて詳細に説明する。図３における(a)は上面図、(b)は正面図、(c)は底面図、
(d)は背面図、(e)は(d)の切断位置における立断面図である。
これらの図面において、２aはまくらぎＳの側端部の上面を覆う側端部上半固定部材２の上壁であり、その上壁２aの下面には、側端部下半固定部材１の底壁１aと同様に、鋭角な稜線を有する凸条が設けてあるので、まくらぎＳの側端部の上面に載置された上壁２aは滑動する恐れがない。そして上記の上壁２aを囲む位置に、まくらぎＳの側端部Ｓ2の端面前に空隙を残すように端面を覆う上前壁２bを設けると共に、上前壁２bの中央位置の上端部分及び下端部分に、まくらぎＳの側端部Ｓ2の端面を支える空隙維持突起２e、２f、を設けたほか、まくらぎＳの側端部Ｓ2の端面と上前壁２bとの空隙を観察できる１対の窓孔２g、２gが設けてあり、更にまくらぎＳの側端部の上半部分Ｓ2の左側面と右側面とを、それぞれ適切な位置に導くための上左壁２cと上右壁２dとが設けてあるほか、１対の杭板挿通孔２h、２hが形成されている。Furthermore, the structure of the side end upperhalf fixing member 2 that covers the upper half S2 of the side end of the sleeper S will be described in detail with reference to FIG. In FIG. 3, (a) is a top view, (b) is a front view, (c) is a bottom view,
(d) is a rear view, (e) is an elevational sectional view at the cutting position of (d).
In these drawings, 2a is an upper wall of the side end upperhalf fixing member 2 that covers the upper surface of the side end portion of the sleeper S, and a bottom surface of the side end lowerhalf fixing member 1 is provided on the lower surface of theupper wall 2a. Like thewall 1a, since the convex line | wire which has an acute ridgeline is provided, theupper wall 2a mounted in the upper surface of the side edge part of the sleeper S does not have a possibility of sliding. Anupper front wall 2b is provided at the position surrounding theupper wall 2a so as to leave a gap in front of the end surface of the side end S2 of the sleeper S, and an upper end portion at the center position of theupper front wall 2b and In addition to providinggap maintaining protrusions 2e and 2f for supporting the end face of the side end S2 of the sleeper S at the lower end portion, a gap between the end face of the side end S2 of the sleeper S and theupper front wall 2b can be observed 1 A pair ofwindow holes 2g and 2g are provided, and an upperleft wall 2c and an upper right wall for guiding the left side surface and the right side surface of the upper half S2 of the side end portion of the sleeper S to appropriate positions, respectively. 2d and a pair of pileboard insertion holes 2h, 2h are formed.

そして、このような側端部下半固定部材１の上縁に近い左右の側面には、左ボルト挿通孔を設けた左下結合片１mと、右ボルト挿通孔を設けた右下結合片１nとが、左右１対として鏡面対称状に水平に突設されている。また、側端部上半固定部材２の下縁に近い左右の側面には、左ボルト挿通孔を設けた左上結合片２mと、右ボルト挿通孔を設けた右上結合片２nとが、左右１対として鏡面対称状に水平に突設されている。そして、これらの側端部下半固定部材１と側端部上半固定部材２とが、同じまくらぎＳの同じ側端部の下半部分と上半部分とに上下に取り付けられると、左下結合片１mの上方に左上結合片２mが位置すると同時に、右下結合片１nの上方に右上結合片２nが位置することになるので、左ボルト挿通孔と左ボルト挿通孔とに、ボルトとナットからなる左緊締具３を挿通して、左下結合片１mと左上結合片２mを緊密に結合することができ、また右ボルト挿通孔と右ボルト挿通孔とに、ボルトとナットからなる右緊締具４を挿通して、右下結合片１nと右上結合片２nを緊密に結合することもできる。従ってまくらぎＳの同じ側端部は、側端部上半固定部材２と側端部下半固定部材１との間に挟まれ、上下から確実に締め付けられる結果、鋼材などで製造された左右何れかの緊締具３又は４が破壊しない限り、装置が分解する恐れはない。  Then, on the left and right side surfaces close to the upper edge of such a side end lowerhalf fixing member 1, a leftlower coupling piece 1m provided with a left bolt insertion hole and a rightlower coupling piece 1n provided with a right bolt insertion hole are provided. , And a pair of left and right, which are horizontally projected in a mirror-symmetric manner. In addition, on the left and right side surfaces near the lower edge of the side end upperhalf fixing member 2, an upperleft coupling piece 2m provided with a left bolt insertion hole and an upperright coupling piece 2n provided with a right bolt insertion hole are provided on the left and right sides. As a pair, it protrudes horizontally in a mirror-symmetric manner. And if these side edge part lowerhalf fixing members 1 and side edge part upperhalf fixing members 2 are attached to the lower half part and the upper half part of the same side edge part of the same sleeper S vertically, Since the upperleft coupling piece 2n is located above the lowerright coupling piece 1n at the same time as the upperleft coupling piece 2m is located above thepiece 1m, the bolt and nut are connected to the left bolt insertion hole and the left bolt insertion hole. The lower left connectingpiece 1m and the upper left connectingpiece 2m can be tightly connected by inserting theleft tightening tool 3 and theright tightening tool 4 comprising a bolt and a nut in the right bolt insertion hole and the right bolt insertion hole. The lowerright coupling piece 1n and the upperright coupling piece 2n can be tightly coupled. Accordingly, the same side end portion of the sleeper S is sandwiched between the side end upperhalf fixing member 2 and the side end lowerhalf fixing member 1 and is securely tightened from above and below. As long as thefastener 3 or 4 is not broken, there is no risk of the device being disassembled.

このようにして、まくらぎＳに、側端部下半固定部材１と、側端部上半固定部材２と、左緊締具３及び右緊締具４とを組み付けて形成された中間組立装置は、上端位置に１対の杭板挿通孔２h、２hが開口していて、これにまくらぎＳの側端部Ｓ0の端面と、側端部上半固定部材２の上前壁２bの内面と側端部下半固定部材１の下前壁１bの内面と、の間に残された縦の空隙が続き、その空隙の最後は１対の杭板挿通孔１k、１kの開口で終わっている。  Thus, the intermediate assembly apparatus formed by assembling the side end lowerhalf fixing member 1, the side end upperhalf fixing member 2, theleft fastening tool 3 and theright fastening tool 4 to the sleeper S, A pair of pileplate insertion holes 2h and 2h are opened at the upper end position, and the end surface of the side end S0 of the sleeper S and the inner surface and side of theupper front wall 2b of the side end upper half fixing member 2 A vertical gap left between the inner surface of thelower front wall 1b of the end lowerhalf fixing member 1 continues, and the end of the gap ends with the opening of a pair of pileplate insertion holes 1k, 1k.

そこで上記の中間組立装置内に残された縦の空隙には、図４及び図５に示すような構造の、例えば振動減衰能を有するＦＣＤ４５０等の鋳鉄材製などの座屈防止杭板５を、装置上端の杭板挿通孔２hから挿入して、下端の杭板挿通孔１kから突出させるが、座屈防止杭板５の挿入過程は、上前壁２bや下前壁１bに設けてある窓孔２gや窓孔１gを介して観察でき、更には、これらの窓孔２gや窓孔１gから差し込んだ固定ボルト６を、座屈防止杭板５の雌ネジ孔５bに螺着して、座屈防止杭板５を上前壁２bや下前壁１bに結合すれば、完成後の本発明のレール座屈防止用保安装置での座屈防止杭板５取付位置が、変動することを抑制できる。  Therefore, in the vertical gap left in the intermediate assembly apparatus, a bucklingprevention pile plate 5 made of a cast iron material such as FCD450 having a vibration damping capability, as shown in FIGS. 4 and 5, is provided. It is inserted from the pileplate insertion hole 2h at the upper end of the apparatus and protrudes from the pileplate insertion hole 1k at the lower end. The insertion process of the bucklingprevention pile plate 5 is provided in the upperfront wall 2b and the lowerfront wall 1b. It can be observed through thewindow hole 2g and thewindow hole 1g, and further, the fixingbolt 6 inserted through thewindow hole 2g and thewindow hole 1g is screwed into thefemale screw hole 5b of the bucklingprevention pile board 5, If the bucklingprevention pile board 5 is joined to the upperfront wall 2b and the lowerfront wall 1b, the bucklingprevention pile board 5 mounting position in the rail buckling prevention safety device of the present invention after completion will change. Can be suppressed.

ところで本発明のレール座屈防止用保安装置Aにおいて、上記のように座屈防止杭板５の取付位置を固定すると、道床などの土質の違いに対応できない場合には、座屈防止杭板５の形状や寸法などの変更が容易でなくなる恐れがある。そこで本発明のレール座屈防止用保安装置に装着される座屈防止杭板５は、固定を解除できるよう構成されているが、選択可能な交換部品として、機能や性能が異なる複数種類の座屈防止杭板を準備することは当然に必要である。そこで機能の異なる座屈防止杭板７として、図６に示した部品の使用について、以下に説明する。  By the way, in the rail buckling prevention safety device A of the present invention, when the mounting position of the bucklingprevention pile plate 5 is fixed as described above, if it is not possible to cope with the difference in soil quality such as the road bed, the bucklingprevention pile plate 5 There is a risk that it will not be easy to change the shape, dimensions, etc. Therefore, the bucklingprevention pile 5 attached to the rail buckling prevention safety device of the present invention is configured to be able to release the fixation, but as a selectable replacement part, a plurality of types of seats having different functions and performances are available. It is of course necessary to prepare an anti-bending pile. Therefore, the use of the components shown in FIG. 6 as the bucklingprevention pile plate 7 having different functions will be described below.

図６に示した座屈防止杭板７は、道床への打ち込みを容易にするために、板幅を先に向かって細くしてあるほか、戻り止め用突起７cが連設されており、また座屈防止杭板５に設けてある雌ネジ孔５bに代えて、摺動スリット７bを設けてなるものである。このような座屈防止杭板７を装置上端の杭板挿通孔２hから挿入し、摺動スリット７bに沿って移動可能としたガイドピンを、窓孔２gや窓孔１gなどに取り付けてなる本発明のレール座屈防止用保安装置Bは、杭板挿通孔１kから座屈防止杭板７の先端が突出して道床内に入っている形態をとるので、まくらぎＳの振動が道床と座屈防止杭板７の間に位相差のある振動を起こし、結果として座屈防止杭板７が摺動スリット７bの長さの範囲内で更に深く、沈み込むことができる。  The bucklingprevention pile plate 7 shown in FIG. 6 has a plate width narrowed toward the front in order to facilitate driving into the road bed, and is provided with adetent projection 7c. Instead of thefemale screw hole 5b provided in the bucklingprevention pile plate 5, a slidingslit 7b is provided. A book in which such a bucklingprevention pile plate 7 is inserted from a pileplate insertion hole 2h at the upper end of the apparatus, and a guide pin which is movable along the slidingslit 7b is attached to thewindow hole 2g, thewindow hole 1g or the like. The rail buckling prevention safety device B according to the present invention takes a form in which the tip of the bucklingprevention pile plate 7 protrudes from the pileplate insertion hole 1k and enters the road bed, so that the vibration of the sleeper S is buckled with the road bed. As a result, a vibration having a phase difference is caused between theprevention pile plates 7, and as a result, the bucklingprevention pile plate 7 can be submerged deeper within the length of the slidingslit 7b.

また、本発明のレール座屈防止用保安装置については、これまで、まくらぎＳの一方の側端部に本発明のレール座屈防止用保安装置を設けることの説明をしてきた。しかしながら、この本発明の装置は、本質的に左右対称な構造を有していて、これまた左右対称な構造を有するまくらぎＳの、他方の側端部に本発明のレール座屈防止用保安装置を設けることに、何等の不自然さもない。従って１個のまくらぎＳの双方の側端部に、それぞれ本発明のレール座屈防止用保安装置を設けることは、効果が倍となることを意味し、鉄道の線路が２本のレールで構成されていることから見ても、合理的と言える。  Moreover, about the rail buckling prevention safety device of the present invention, it has been described so far that the rail buckling prevention security device of the present invention is provided at one side end of the sleeper S. However, this device of the present invention has an essentially symmetrical structure, and the rail buckling prevention security of the present invention is provided at the other side end of the sleeper S having the symmetrical structure. There is no unnaturalness in providing the device. Therefore, providing the rail buckling prevention safety device of the present invention at both side ends of one sleeper S means that the effect is doubled, and the railroad track is composed of two rails. It can be said that it is reasonable even if it is composed.

そうであれば、鉄道の線路には多数のまくらぎが道床上に所定の間隔で配置されていることを考えれば、道床が築造された地盤における土質の安定性を補うために、隣接するまくらぎに本発明のレール座屈防止用保安装置を、所望の数だけ次々に設けることが有効であると言え、こうした本発明の施工形態の例を、図８に示す。此の例では、隣接したまくらぎＳ、Ｓの一方側端部のそれぞれに、例えばレール座屈防止用保安装置Ｂを設けると共に、一方の保安装置Ｂの左緊締具３の上端部と、その左隣の保安装置Ｂの右緊締具４の上端部とを、端子部材８aと延長部材８bとをボルトナット結合して成る連結装置８で、連結するなどの手段を用いて、まくらぎＳ、Ｓの間隔を所望の値となるよう固定したものである。  If this is the case, considering that a large number of sleepers are arranged on the roadbed at predetermined intervals on the railroad tracks, adjacent pillows are used to supplement the soil stability in the ground where the roadbed is built. It can be said that it is effective to provide a desired number of rail buckling prevention safety devices according to the present invention one after another. FIG. 8 shows an example of the construction mode according to the present invention. In this example, for example, a rail buckling prevention safety device B is provided at each of the one end portions of the adjacent sleepers S, S, and the upper end portion of the leftelastic fastener 3 of one safety device B, The sleeper S, using means such as connecting the upper end portion of theright fastener 4 of the security device B on the left side with the connecting device 8 formed by connecting theterminal member 8a and the extendingmember 8b with bolts and nuts. The interval of S is fixed to a desired value.

次に、既存の鉄道の線路に本発明のレール座屈防止用保安装置を設置する場合について説明する。
線路における設置を望む位置にあるレールとまくらぎとを外した後、前記の中間組立装置を道床上に配設して、通常の線路取替作業の手順に準じてレールの取付作業を進め、レールの取付位置修正が終わった時点で、座屈防止杭板を中間組立装置の杭板挿通孔２hに挿入し、座屈防止杭板の頭５aを打撃するか又は押圧するなどの手段により、座屈防止杭板を必要な深さまで道床内に沈下させて、本発明のレール座屈防止用保安装置を完成させる。なお、このような座屈防止杭板の取付作業の間には、所望に応じて固定ボルト６などの取り付け又は締め付け等の作業を進めることが、望ましい。Next, the case where the rail buckling prevention safety device of the present invention is installed on an existing railway track will be described.
After removing the rails and sleepers at the desired location on the track, arrange the intermediate assembly device on the roadbed, and proceed with the rail mounting work according to the normal track replacement procedure, When the rail mounting position correction is completed, the buckling prevention pile plate is inserted into the pileplate insertion hole 2h of the intermediate assembly device, and thehead 5a of the buckling prevention pile plate is hit or pressed, etc. The buckling prevention pile board is sunk in the road bed to a required depth to complete the rail buckling prevention safety device of the present invention. In addition, during the attachment work of such a buckling prevention pile board, it is desirable to advance work, such as attachment or fastening, etc. of the fixingbolt 6 as needed.

本発明のレール座屈防止用保安装置は、本来の目的であった、気温の高い季節においてレールの温度が特に上昇し、レールが伸長して座屈をおこす事故の防止は、実用試験によって、略満足できる成果が得られることが判ったが、本装置の構造並びに作用機構から考えて、単にレールの座屈防止と言うに止まらず、地上に敷設された鉄道施設に対する保安装置として、広く応用することが期待される。  The rail buckling prevention safety device of the present invention was originally intended to prevent an accident in which the rail temperature particularly rises during the high temperature season and the rail extends to cause buckling. Although it has been found that satisfactory results can be obtained, considering the structure and operation mechanism of this device, it can be applied widely as a safety device for railway facilities laid on the ground, not just to prevent rail buckling. Is expected to do.
