Description

本発明は鉄道用分岐器の曲線レールに関する。   The present invention relates to a curved rail of a railway branching device.

従来から図4〜図6に示すとおり、鉄道用分岐器に使用される曲レール1、具体的には曲トングレール1a、曲リードレール1bは、車輪踏面4がレール頭頂面2の中央部に接触して走行するように曲線レール1および曲線内側レール1′を図4のレール中心垂線bに対し、角θ軌間内側3′に傾斜させて敷設している。このため図3で示すようにレール磨耗が発生すると、鉄道分岐器内の外軌側Oの曲線レール1を走行する車輪踏面4は外側走行点cに接触して走行する。この結果、車輪踏面4および車輌フランジ7は曲線レール1に押し付けられ、円滑に走行しずらく、外軌側の曲線レール1の軌間内側dに磨耗がより大きく発生し、レールの交換周期が短くなり不経済になる。   Conventionally, as shown in FIG. 4 to FIG. 6, the curved rail 1, specifically the curved tongue rail 1 a and the curved lead rail 1 b used in the railway branching device have the wheel tread 4 at the center of the rail top surface 2. The curved rail 1 and the curved inner rail 1 'are laid so as to incline on the inner side 3' between the angle θ and the rail center perpendicular line b in FIG. Therefore, as shown in FIG. 3, when rail wear occurs, the wheel tread 4 traveling on the curved rail 1 on the outer gauge side O in the railroad branching unit contacts the outer travel point c and travels. As a result, the wheel tread 4 and the vehicle flange 7 are pressed against the curved rail 1 and do not travel smoothly, more wear occurs on the inner side d of the curved rail 1 on the outer gauge side, and the rail replacement cycle is shorter. It becomes uneconomical.

前記説明を図6をもってすると、一般に分岐器内を輪軸が走行する場合、分岐曲線内を走行するときに発生する遠心力(太矢印)により、外側の車輪4aの車輪フランジ7が、曲線レール1の軌間内側3′に沿って走行する。この走行が経年続くと、磨耗した分岐器内の曲線レール1において、車輪踏面4がレール頭頂面2の外側走行点cに接触して走行するようになり、曲線走行がしにくくなる。なお、車輪踏面4がレール頭頂面2の中央部aよりも外側走行点cに接触して走行する場合の方が曲線走行がしにくく、曲線レールが、より磨耗する点については後述の作用の点で詳説する。
なし。
Referring to FIG. 6, the wheel flange 7 of the outer wheel 4a is caused to move to the curved rail 1 by the centrifugal force (thick arrow) generated when traveling in the branching curve. It travels along the inside 3 'of the gauge. If this running continues over the years, the curved rail 1 in the worn branching device will run while the wheel tread surface 4 comes into contact with the outer running point c of the rail top surface 2, and the curved running becomes difficult. In the case where the wheel tread 4 travels in contact with the outer travel point c than the central portion a of the rail top surface 2, the curve travel is less likely to occur, and the curve rail is more worn out. Detailed explanation in terms of points.
None.

本発明は、鉄道用分岐器に使用する曲線レールにおいて、車輪の曲線通過を円滑にし、外軌側の曲線レールに生じる磨耗を軽減させることを課題とする。   This invention makes it a subject to make the curve curve of a curve used for a railway branching device smooth, and to reduce the wear which arises in the curve rail of an outer track side.

本発明の第1の手段は、外軌側の曲線レールのレール頭頂面における外軌側に車輪踏面との離間面を形成し、しかも前記離間面をレール長手方向に形成することを特徴とするものである。 The first means of the present invention is characterized in that a separation surface from the wheel tread surface is formed on the outer rail side of the rail top surface of the curved rail on the outer rail side, and the separation surface is formed in the rail longitudinal direction. Is.

本発明の第2の手段は、第1の手段において、外軌側の曲線レールが曲トングレールおよび曲リードレールの少なくとも一方であることを特徴とするものである。 The second means of the present invention is characterized in that, in the first means, the curved rail on the outer track side is at least one of a curved tong rail and a curved lead rail.

本発明の第3の手段は、第1の手段において、離間面が既存の外軌側の曲線レールを研削若しくは切削加工により形成されたことを特徴とするものである。 The third means of the present invention is characterized in that, in the first means, the separation surface is formed by grinding or cutting an existing curved rail on the outer gauge side.

請求項1、2の本発明によれば、輪軸の曲線走行が円滑となり、外軌側の曲線レールの軌間内側の磨耗が軽減されて、レール交換の周期が長くなり、経済的である。   According to the first and second aspects of the present invention, the curve traveling of the wheel shaft becomes smooth, wear on the inner side of the curved rail on the outer track side is reduced, and the rail replacement cycle becomes longer, which is economical.

請求項3の本発明によれば既存のレールを加工するだけで足り、安価に提供することができる。   According to the present invention of claim 3, it is only necessary to process the existing rail, and it can be provided at a low cost.

本発明は鉄道用分岐器において、曲線レール1、具体的には曲トングレール1a、曲リードレール1bのレール頭頂面2における外軌側、具体的にはレール頭頂面2の中心部aより外側部分を外側に行くに従って低くなるように傾斜させて図1、2実線、図3破線で示す車輪踏面4との非接触部つまり離間面5を形成し、この離間面5を部分的にレール長手方向に形成する。   The present invention relates to a railroad branching device, which is an outer rail side of a rail rail top surface 2 of a curved rail 1, specifically, a curved tongue rail 1a and a curved lead rail 1b, specifically, outside a central portion a of the rail top surface 2. The portion is inclined so as to become lower as it goes outward to form a non-contact portion, that is, a separation surface 5 with the wheel tread surface 4 shown by solid lines in FIGS. Form in the direction.

具体的には前記離間面5は既存の曲線レール1、より具体的には曲トングレール1a、曲リードレール1bを研削や切削して加工形成する。   Specifically, the spacing surface 5 is formed by grinding or cutting an existing curved rail 1, more specifically, a curved tongue rail 1a and a curved lead rail 1b.

次に作用についてまず原理を図解する。   Next, the principle of action will be illustrated first.

図7で示すように車輪4aにおいて、レールとの接点4bとレールとの接点4cにおいて、走行する車輪の直径が異なる。車輪の踏面勾配によって、車輪の軌間内側の直径Lよりも、軌間外側の直径lの方が小さい。つまり符号4bの方が符号4cを走行点とする場合より直径が小さい。   As shown in FIG. 7, in the wheel 4a, the diameter of the traveling wheel is different between the contact 4b with the rail and the contact 4c with the rail. Due to the tread surface gradient of the wheel, the diameter l outside the gauge is smaller than the diameter L inside the gauge between the wheels. That is, the diameter of the reference numeral 4b is smaller than that of the case where the reference numeral 4c is a traveling point.

図8は、走行点が左右異なる直径l、Lの輪軸がレールを転がる場合に、その輪軸は直径の小さい車輪の側に転向(矢印図示)されて曲線上を円滑に転がる原理を示すものである。つまり転向の度合いは直径の差が大きいほど大きくなる。仮に直径の差がなく、同一であるならば、輪軸は直行する方向に力が働き、これを転向させるにはレールに大きい摩擦を生じさせ、円滑転向は極めて困難である。   FIG. 8 shows the principle that when a wheel shaft with diameters 1 and L with different traveling points on the left and right rolls on the rail, the wheel shaft is turned to the side of the wheel with the smaller diameter (shown by an arrow) and smoothly rolls on the curve. is there. That is, the degree of turning increases as the difference in diameter increases. If there is no difference in diameter and the diameters are the same, a force acts in a direction perpendicular to the wheel shaft, causing a large friction on the rail to turn it, and smooth turning is extremely difficult.

ここに軌間内側3′に傾斜されている分岐内曲線レール1を走行する車輪4aの輪軸は、図3の符号cで示す外軌側の小さい直径で転がる場合よりも図1の符号aで示す大きい直径で曲線を転がる場合の方が図8で示すように左右異なる車輪の直径差が大きくなり、曲線の曲がる方向に円滑に転向され、車輪フランジ7による外軌側の曲線レール1を押す力が緩和される。このため、車輪フランジ7による曲トングレール1aおよび曲リードレール1bの軌間内側3′特に符号d位置に発生する磨耗が軽減される。   Here, the wheel shaft of the wheel 4a traveling on the in-branch curved rail 1 inclined to the inner side 3 'of the gauge is indicated by reference sign a in FIG. 1 rather than rolling with a smaller diameter on the outer gauge side indicated by reference sign c in FIG. In the case of rolling a curve with a large diameter, as shown in FIG. 8, the diameter difference between the left and right wheels becomes larger, and the wheel flange 7 smoothly turns in the direction of the curve and pushes the curved rail 1 on the outer gauge side by the wheel flange 7. Is alleviated. For this reason, the abrasion which generate | occur | produces in the gauge inside 3 'especially the code | symbol d position of the curved tongue rail 1a and the curved lead rail 1b by the wheel flange 7 is reduced.

分岐内曲線レール1の頭頂面2の外側面を離間面5のように非接触面として形成することにより、外軌側の曲線レール1を走行する車輪踏面4における車輪の直径が、車輪の踏面勾配により、曲線レール頭頂面を加工しない場合と比較して大きくなる。   By forming the outer surface of the top surface 2 of the branched curve rail 1 as a non-contact surface like the separation surface 5, the wheel diameter of the wheel tread 4 running on the outer rail side curved rail 1 becomes the tread surface of the wheel. Due to the gradient, it becomes larger than the case where the top surface of the curved rail is not machined.

つまり、分岐器における曲線レール1の頭頂面2の曲線外側面をレール長手方向に切削あるいは研削により加工することにより、車輪4aはレール頭頂面2の曲線外軌側で走行しなくなるため、車輪4aがレール頭頂面2に接触する点の位置における車輪直径が小さくなることがなくなり、輪軸は曲線内側の方向に曲げられて走行しやすくなり、車輪フランジが外軌側の曲線レールに押し付けられる力が緩和され、曲線レールの軌間内側の磨耗が軽減されて、レール交換の周期が長くなり経済的効果が生じる。   In other words, by cutting or grinding the curved outer surface of the top surface 2 of the curved rail 1 in the turnout in the longitudinal direction of the rail, the wheel 4a does not travel on the curved outer track side of the rail top surface 2, so the wheel 4a The wheel diameter at the point of contact with the rail top surface 2 is no longer reduced, the wheel shaft is bent toward the inside of the curve, and it becomes easy to travel, and the force that the wheel flange is pressed against the curved rail on the outer gauge side is increased. It is alleviated, wear on the inside of the rail between the curved rails is reduced, and the period of rail replacement becomes longer, resulting in an economic effect.

また本発明により外軌側の一部を加工した分岐内曲線レールは、図4、6で示す従来技術による締結装置8によりまくらぎに締結して実用に供することができる。   Moreover, the curve rail in a branch which processed a part by the side of an outer track by this invention can be fastened to a sleeper with the fastening device 8 by the prior art shown in FIG.
