Description

本発明は、鉄道レールを修正する鉄道レール修正車両に関する。   The present invention relates to a railway rail correction vehicle that corrects railway rails.

鉄道レールは車両の往来によって内側が摩耗する傾向にある。すなわち、車両を構成する車輪は内側の直径より外側の直径が小さく形成されていて、鉄道レールのカーブを車両が通過する際に車両が遠心力の作用によりカーブの外側に移動すると、カーブの内側の鉄道レールには直径の小さい車輪の外側が位置づけられ、カーブの外側の鉄道レールには直径の大きい車輪の内側が位置づけられて車両が円滑にカーブを通過できるようになっていることから、鉄道レールの向かい合う内側が摩耗する。そのため、鉄道レール修正車両によって定期的に鉄道レールの上面が平坦になるように研削されて修正される(たとえば特許文献1参照。)。   Railroad rails tend to wear on the inside due to vehicle traffic. That is, the wheels constituting the vehicle are formed to have a smaller outside diameter than the inside diameter, and when the vehicle moves to the outside of the curve by the action of centrifugal force when the vehicle passes the curve of the railway rail, the inside of the curve is Because the outside of the small diameter wheel is positioned on the railway rail of the railway and the inside of the large diameter wheel is positioned on the railway rail on the outside of the curve so that the vehicle can pass through the curve smoothly. Wear on the inside opposite of the rails. Therefore, the upper surface of the rail is periodically ground and corrected by the rail correction vehicle so that the upper surface of the rail is flat (see, for example, Patent Document 1).

In FIG. 1, the X direction, the Y direction and the Z direction are indicated by arrows X, Y and Z. A railway rail correction vehicle generally indicated by reference numeral 2 in FIG. 1 comprises at least two pairs of wheels 4 disposed in at least the X direction rolling on the railway rails, and a frame 6 rotatably supporting the wheels 4; At least a grinding tool 8 mounted on the frame 6 rotatably around a rotation axis extending in the Z direction and grinding and flattening the upper surface of the railway rail.

図示の実施形態では図2に示すとおり、車輪4は、Y方向において鉄道レールの間隔に対応する間隔をおいて配置された1対の前輪4aと、各前輪4aとX方向に間隔をおいて配置された1対の後輪4bとから構成されている。前輪4a同士及び後輪4b同士は、Y方向に延びる円柱状の車軸10により連結されている。車軸10は、枠体6に固定された適宜の軸受(図示していない。)を介して回転可能に枠体6に支持されている。車輪4の直径はY方向の外側から内側に向かって次第に大きくなっており、車輪4の外周面12はY方向の外側から内側に向かって車輪4の径方向外方に傾斜して延びる傾斜面になっている。また、車輪4のY方向内側端部には、鉄道レールからの脱線を防止するための環状フランジ14が形成されている。   In the illustrated embodiment, as shown in FIG. 2, the wheels 4 are spaced from each other in the X direction from a pair of front wheels 4a disposed at intervals corresponding to the railway rail spacing in the Y direction. It is comprised from a pair of rear wheel 4b arrange | positioned. The front wheels 4 a and the rear wheels 4 b are connected by a cylindrical axle 10 extending in the Y direction. The axle 10 is rotatably supported by the frame 6 via a suitable bearing (not shown) fixed to the frame 6. The diameter of the wheel 4 gradually increases inward from the outer side in the Y direction, and the outer peripheral surface 12 of the wheel 4 is an inclined surface extending in a radially outward direction of the wheel 4 from the outer side in the Y direction. It has become. Further, an annular flange 14 for preventing derailment from the railway rail is formed at the Y-direction inner end of the wheel 4.

図示の実施形態では図1に示すとおり、枠体6は直方体状に形成されている。枠体6の前面板16には貫通開口16aが形成され、貫通開口16aを通ってX方向に突出する連結手18が枠体6に配設されている。そして、鉄道レール修正車両2は、連結手18を介して、電気機関や内燃機関等の適宜の駆動機関を有する機関車(図示していない。)に連結されて牽引されるようになっている。図2に示すとおり、枠体6の底面板20には、円形開口20aと矩形開口20bとが4個ずつ形成されている。各円形開口20aには軸受22が固定され、軸受22にはZ方向に延びる回転軸心O(図3参照。)を中心として回転自在、かつZ方向に移動自在に研削工具8が支持されている。   In the illustrated embodiment, as shown in FIG. 1, the frame 6 is formed in a rectangular shape. A through opening 16 a is formed in the front plate 16 of the frame 6, and a connecting hand 18 which protrudes in the X direction through the through opening 16 a is disposed on the frame 6. The railway rail correction vehicle 2 is connected to and pulled by a locomotive (not shown) having an appropriate driving engine such as an electric engine or an internal combustion engine via a connecting hand 18. . As shown in FIG. 2, four circular openings 20 a and four rectangular openings 20 b are formed in the bottom plate 20 of the frame 6. A bearing 22 is fixed to each circular opening 20a, and the grinding tool 8 is supported by the bearing 22 rotatably around a rotation axis O (see FIG. 3) extending in the Z direction and movable in the Z direction. There is.

図2に示すとおり、各研削工具8は、軸受22に挿入されZ方向に延びる円柱状のスピンドル24と、スピンドル24の下端に固定された円板状のマウント26と、マウント26の下面に固定された研削砥石28とを含む。図3に示すとおり、研削工具8の回転軸心Oは、鉄道レール30のY方向中心32からY方向に偏心している。そして、研削砥石28の下面が鉄道レール30の上面に接触した状態において図3に矢印X1で示す方向に鉄道レール修正車両2が走行すると、回転軸心Oを中心として図3に矢印Aで示す方向に研削工具8が連れ回りで回転して鉄道レール30の上面を研削砥石28によって研削するようになっている。鉄道レール30を研削するための研削砥石28は、ダイヤモンド砥粒を適宜のボンド(たとえば、レジンボンド、ビトリファイドボンド又はメタルボンドでよい。)で固定することにより構成され得る。図示の実施形態では、前輪4a側に位置する1対の研削工具8の研削砥石28は、後輪4b側に位置する1対の研削工具8の研削砥石28の砥粒よりも粒度が大きい砥粒から構成されている。すなわち、前輪4a側の1対の研削工具8は粗研削用、後輪4b側の1対の研削工具8は仕上げ研削用となっている。なお、研削砥石28は、円板状でも環状でもよく、あるいは環状に配置された複数個の研削砥石から構成されていてもよい。   As shown in FIG. 2, each grinding tool 8 is fixed to the lower surface of a cylindrical spindle 24 inserted in the bearing 22 and extending in the Z direction, a disk-like mount 26 fixed to the lower end of the spindle 24, and the mount 26. And a grinding wheel 28. As shown in FIG. 3, the rotation axis O of the grinding tool 8 is eccentric from the Y-direction center 32 of the railway rail 30 in the Y-direction. Then, when the railway rail correction vehicle 2 travels in the direction shown by arrow X1 in FIG. 3 with the lower surface of the grinding stone 28 in contact with the upper surface of the railway rail 30, it is shown by arrow A in FIG. The grinding tool 8 is rotated in the direction to grind the upper surface of the railway rail 30 by the grinding wheel 28. The grinding wheel 28 for grinding the railway rail 30 may be configured by fixing diamond abrasive grains with an appropriate bond (for example, a resin bond, a vitrified bond or a metal bond). In the illustrated embodiment, the grinding wheels 28 of the pair of grinding tools 8 located on the front wheel 4 a side have a grain size larger than the abrasive grains of the grinding wheels 28 of the pair of grinding tools 8 located on the rear wheel 4 b side. It is composed of grains. That is, the pair of grinding tools 8 on the front wheel 4a side is for rough grinding, and the pair of grinding tools 8 on the rear wheel 4b side is for finishing grinding. The grinding wheel 28 may have a disk shape, an annular shape, or a plurality of grinding wheels arranged in an annular shape.

図示の実施形態では図2に示すとおり、各研削工具8には、連結機構34を介して、鉄道レール30のY方向の傾斜に倣って作動する傾斜作動手段36が連結されている。連結機構34は、各研削工具8のスピンドル24の上端に装着されたロータリージョイント38と、ロータリージョイント38の上面から上方に延びる第一のワイヤ40と、一端部が第一のワイヤ40の上端部に連結された伝達片42とを含む。Y方向に沿って配置されている伝達片42は、X方向に延びる支持ピン44を中心として揺動自在に支持ピン44に支持されている。伝達片42の他端部には、第二のワイヤ46及び複数個(図示の実施形態では3個)の滑車48を介して傾斜作動手段36が連結されている。なお、支持ピン44は適宜のブラケット(図示していない。)等を介して枠体6の内部に固定され、各滑車48は適宜の支持ピン及びブラケット(いずれも図示していない。)等を介して回転自在に枠体6に装着されている。   In the illustrated embodiment, as shown in FIG. 2, each grinding tool 8 is connected with inclination operation means 36 that operates according to the inclination of the railway rail 30 in the Y direction via the connection mechanism 34. The connection mechanism 34 includes a rotary joint 38 attached to the upper end of the spindle 24 of each grinding tool 8, a first wire 40 extending upward from the upper surface of the rotary joint 38, and an upper end of the first wire 40 at one end. And a transmission piece 42 connected thereto. The transmission piece 42 disposed along the Y direction is supported by the support pin 44 so as to be pivotable about the support pin 44 extending in the X direction. The other end of the transmission piece 42 is connected to a tilt operation means 36 via a second wire 46 and a plurality of (three in the illustrated embodiment) pulleys 48. The support pin 44 is fixed to the inside of the frame 6 through an appropriate bracket (not shown) or the like, and each pulley 48 is an appropriate support pin and a bracket (both are not shown). It is rotatably mounted on the frame 6 via the same.

図2、図4及び図5を参照して傾斜作動手段36について説明する。なお、図4及び図5においては、傾斜作動手段36の作動に応じて研削工具8が昇降することを説明するために、便宜上傾斜作動手段36と研削工具8とを並べて記載しているが、図示の実施形態では図2に示すとおり、相互に連結されている傾斜作動手段36と研削工具8とはX方向に沿って配置されている。傾斜作動手段36は、第二のワイヤ46に連結され枠体6の底面板20の矩形開口20bを通って底面板20の下方に突出する板状部材50と、板状部材50の下端に固定された支持部材52と、支持部材52に回転自在に支持された転輪54とを含む。図4及び図5に示すとおり、鉄道レール30の幅寸法に対応する幅寸法に形成されている転輪54は、鉄道レール30で転動するようになっている。また、転輪54のY方向の内側端部及び外側端部には、鉄道レール30からの脱線を防止するための1対の環状フランジ56が形成されている。支持部材52は、コイルばね等の弾性部材を有する連結部材58を介して揺動自在に底面板20の下面に連結されている。これにより、図5に示すとおり、転輪54が転動する鉄道レール30の上面が摩耗して傾斜している場合、枠体6の底面板20に対して転輪54と共に支持部材52が揺動するようになっている。また、底面板20に対して転輪54と共に支持部材52が揺動すると、支持部材52が固定されている板状部材50も底面板20に対して揺動する。このため、板状部材50の外面と底面板20の矩形開口20bの内周面との間には、図4及び図5に示すとおり、枠体6に対する板状部材50の揺動を許容するための間隙Gが存在する。このように傾斜作動手段36においては、鉄道レール30のY方向の傾斜に倣って作動(揺動)するようになっている。そして、図示の実施形態では図4に示すとおり、摩耗しておらず平坦な鉄道レール30を鉄道レール修正車両2が走行している際は、傾斜作動手段36の板状部材50が底面板20に対してほぼ垂直となり、連結機構34を介して傾斜作動手段36に連結された研削工具8は、鉄道レール30の上面と研削砥石28の下面とが離間する離間位置に傾斜作動手段36によって位置づけられる。一方、図5に示すとおり、内側が摩耗した鉄道レール30を鉄道レール修正車両2が走行している際は、傾斜作動手段36が底面板20に対して揺動するため、研削工具8は、自重により鉄道レール30の上面と研削砥石28の下面とが接触する研削位置に位置することとなる。すなわち、鉄道レール30のY方向の傾斜に倣って傾斜作動手段36が作動するのに応じて、研削工具8は離間位置と研削位置との間を昇降するようになっている。したがって図示の実施形態では、鉄道レール30が摩耗している部分のみ研削工具8によって研削される。また、図示の実施形態では、鉄道レール30のY方向の傾斜角度(すなわち鉄道レール30の内側の摩耗量)に応じて底面板20に対する傾斜作動手段36の揺動角度が変化し、傾斜作動手段36の揺動角度に応じて離間位置からの研削工具8の下降量が変化する。すなわち、鉄道レール30の摩耗量に応じて傾斜作動手段36が作動し、傾斜作動手段36の作動に応じて研削工具8による鉄道レール30の研削量が調整される。   The tilt actuating means 36 will be described with reference to FIGS. 2, 4 and 5. Although FIGS. 4 and 5 illustrate the tilting operation means 36 and the grinding tool 8 side by side for the sake of convenience in order to explain that the grinding tool 8 moves up and down according to the operation of the inclination operation means 36, In the illustrated embodiment, as shown in FIG. 2, the mutually connected tilting actuating means 36 and the grinding tool 8 are arranged along the X direction. The inclination actuating means 36 is fixed to the lower end of the plate member 50 and the plate member 50 connected to the second wire 46 and projecting downward of the bottom plate 20 through the rectangular opening 20 b of the bottom plate 20 of the frame 6. And a roller 54 rotatably supported by the support member 52. As shown in FIGS. 4 and 5, the rolling wheels 54 formed in a width dimension corresponding to the width dimension of the railway rail 30 roll on the railway rail 30. In addition, a pair of annular flanges 56 for preventing derailment from the railway rail 30 is formed at the inner end and the outer end of the wheel 54 in the Y direction. The support member 52 is swingably connected to the lower surface of the bottom plate 20 via a connection member 58 having an elastic member such as a coil spring. Thereby, as shown in FIG. 5, when the upper surface of the railway rail 30 on which the rolling wheel 54 rolls is worn and inclined, the supporting member 52 swings together with the rolling wheel 54 with respect to the bottom plate 20 of the frame 6. It is supposed to move. In addition, when the support member 52 swings with the wheel 54 relative to the bottom plate 20, the plate-like member 50 to which the support member 52 is fixed also swings relative to the bottom plate 20. Therefore, between the outer surface of the plate member 50 and the inner peripheral surface of the rectangular opening 20b of the bottom plate 20, as shown in FIG. 4 and FIG. There is a gap G for this. As described above, the tilt operation means 36 operates (swings) in accordance with the tilt of the railway rail 30 in the Y direction. And, in the illustrated embodiment, as shown in FIG. 4, when the rail correction vehicle 2 travels on the flat railway rail 30 which is not worn, the plate-like member 50 of the inclination actuating means 36 is the bottom plate 20. The grinding tool 8 which is substantially perpendicular to the surface and connected to the inclination operation means 36 via the connection mechanism 34 is positioned by the inclination operation means 36 at a separated position where the upper surface of the railway rail 30 and the lower surface of the grinding wheel 28 are separated. Be On the other hand, as shown in FIG. 5, when the rail correction vehicle 2 is traveling on the railway rail 30 whose inner side is worn, the inclination actuating means 36 swings with respect to the bottom plate 20, so the grinding tool 8 Due to its own weight, the upper surface of the railway rail 30 and the lower surface of the grinding wheel 28 are positioned at the grinding position where they contact each other. That is, in accordance with the inclination of the railway rail 30 in the Y direction, the grinding tool 8 is moved up and down between the separated position and the grinding position according to the operation of the inclination actuating means 36. Thus, in the illustrated embodiment, only the portion where the railway rail 30 is worn is ground by the grinding tool 8. Further, in the illustrated embodiment, the swing angle of the tilt operating means 36 with respect to the bottom plate 20 changes according to the tilt angle of the railway rail 30 in the Y direction (i.e., the amount of wear on the inner side of the rail 30). The lowering amount of the grinding tool 8 from the separated position changes in accordance with the swing angle of 36. That is, the inclination operation means 36 operates according to the amount of wear of the railway rail 30, and the amount of grinding of the rail 30 by the grinding tool 8 is adjusted according to the operation of the inclination operation means 36.

上述の鉄道レール修正車両2によって、向かい合う内側が摩耗した鉄道レール30を修正する際は、鉄道レール修正車両2の連結手18を機関車に連結する。次いで、機関車によって鉄道レール修正車両2を牽引する。そして、鉄道レール30が摩耗している部分に鉄道レール修正車両2が差し掛かると、傾斜作動手段36が作動して研削工具8が研削位置に位置するので、回転軸心Oを中心として研削工具8が連れ回りで回転して鉄道レール30の上面が研削砥石28によって研削される。したがって、鉄道レール修正車両2は、鉄道レール30の上面を研削して平坦になるように修正することができる。   When correcting the rail rails 30 which are worn on the inside facing each other by the above-described rail correction vehicle 2, the connecting hand 18 of the rail correction vehicle 2 is connected to the locomotive. Then, the railway rail correction vehicle 2 is towed by the locomotive. Then, when the railway rail correction vehicle 2 comes to a portion where the railway rail 30 is worn, the inclination operation means 36 operates to position the grinding tool 8 at the grinding position. The upper surface of the railway rail 30 is ground by the grinding wheel 28. Accordingly, the railway rail correction vehicle 2 can be corrected so as to grind and flatten the upper surface of the railway rail 30.

鉄道レール修正車両2においては、走行に伴って研削工具8が連れ回りで回転して鉄道レール30の上面を研削するので、研削工具8を回転させるための回転駆動源を備える必要がない。また、図示の実施形態では、鉄道レール修正車両2は、連結手18を介して機関車に連結されて牽引されるので、鉄道レール修正車両2を走行させるための走行駆動源も備える必要がない。このように鉄道レール修正車両2は簡易に構成され得るので設備費を抑制できる。   In the railway rail correction vehicle 2, since the grinding tool 8 rotates in a rotating manner as it travels to grind the upper surface of the railway rail 30, it is not necessary to provide a rotational drive source for rotating the grinding tool 8. Further, in the illustrated embodiment, the railway rail correction vehicle 2 is connected to and pulled from the locomotive via the coupling hand 18, so that it is not necessary to provide a travel drive source for causing the railway rail correction vehicle 2 to travel. . As described above, since the railway rail correction vehicle 2 can be configured simply, the equipment cost can be suppressed.

なお、研削工具8については、図示の実施形態では研削砥石28を有する例を説明したが、スピンドル24の下端に超鋼切り刃を複数備えたフラットエンドミルが固定されていてもよい。また、研削工具8を支持する軸受22の下面とマウント26の上面との間にコイルばね等の付勢部材を配置して、接触位置に位置した研削工具8の下面を鉄道レール30の上面により強く接触するように研削工具8を付勢するようにしてもよい。   In addition, although the example which has the grinding stone 28 was demonstrated in embodiment of illustration about the grinding tool 8, the flat end mill provided with multiple super steel cutting blades may be fixed to the lower end of the spindle 24. FIG. Further, a biasing member such as a coil spring is disposed between the lower surface of the bearing 22 supporting the grinding tool 8 and the upper surface of the mount 26, and the lower surface of the grinding tool 8 positioned at the contact position is the upper surface of the railway rail 30. The grinding tool 8 may be biased to make strong contact.
