Abstract

A grinding frame moving along a rail (1) has two freely turnable grinding tools. The grinding face (12) of a first tool (10) has a contour, which covers only the upper running face (2) of the rail, and a second tool has a grinding face for one of the two side edges (3,4) of the rail next to the upper face. The tool is supported in direction of contact pressure against the running faces and relative to the frame, by a spring body, which can be bridges selectively by a rigid support. The tools have rotational axis (11) enclosing an acute angle with the longitudinal rail direction, and each tool is rotary-symmetrical to its axis.

Description

本発明は、レールの走行面を加工するための装置に関し、特に、レールの走行面で調整可能かつレールに沿って移動可能な研削フレームによって周囲研削を可能とし、この研削フレームがレール長手方向に対して鋭角を成す旋回軸を有する周囲研削に対して自由に回転可能として配置した少なくとも１個の研削部材を具える装置に関するものである。   The present invention relates to an apparatus for processing a running surface of a rail, and in particular, enables peripheral grinding by a grinding frame that is adjustable on the running surface of the rail and is movable along the rail. The invention relates to a device comprising at least one grinding member arranged to be freely rotatable with respect to peripheral grinding having a pivot axis with an acute angle.

鉄道軌道におけるレールの場合、長期にわたる使用により磨耗が生じる。磨耗の主因はレール内の材料変位及び研削部材の亀裂形成にある。   In the case of rails on railway tracks, wear occurs over long periods of use. The main cause of wear is material displacement in the rail and crack formation in the grinding member.

列車車輪が走行する際にレールに引き起こされる力に起因する材料変位によって二つの磨耗現象が生じる。一方ではレールの材料が横方向に変位される。即ち、研削部材では列車の車輪が走行する側から別の側へ材料が変位する。プロファイルの変化が生じ、レールの使用・管理に不利な作用を及ぼす。他方では材料が長手方向に変位し、レール長手方向でうねりが形成される。これらのうねりは列車運行に支障を与え、走行騒音の発生及び騒音被害を増加させる。これらは不所望である。   Two wear phenomena occur due to material displacement due to the forces induced on the rails as the train wheels travel. On the one hand, the rail material is displaced laterally. That is, in the grinding member, the material is displaced from the side on which the train wheel runs to another side. A profile change occurs, which adversely affects the use and management of the rail. On the other hand, the material is displaced in the longitudinal direction and undulations are formed in the longitudinal direction of the rail. These undulations impede train operation and increase the generation of noise and damage. These are undesirable.

材料変位によるレールの過度の損耗及び誘導的な変形を避けるために、レールを成形する鋼鉄は近年まで常に硬く合金されてきた。このため、所望のように損耗磨耗及び材料変形が低減するだけでなく、レールの亀裂形成の傾向が高まる。レールの亀裂は、多くの場合、走行面から始まり、対策が不十分であるとレール材料の内部へ深く拡がる。これらのレール内の亀裂は、特に最近の高速列車にとって危険であり、事故につながる恐れがある。例えば、イギリスにおける重大な鉄道事故は亀裂によるレール破損が原因であった。したがって、レール及び軌条施設の安全確保には、発生する亀裂を早期に処置／解消することが極めて重要である。   In order to avoid excessive wear and inductive deformation of the rail due to material displacement, the steel forming the rail has always been hard alloyed until recently. This not only reduces wear and wear and material deformation as desired, but also increases the tendency for rail cracking. Rail cracks often start from the running surface and deeply extend into the rail material if countermeasures are inadequate. Cracks in these rails are particularly dangerous for modern high-speed trains and can lead to accidents. For example, a major rail accident in the UK was caused by rail breakage due to cracks. Therefore, in order to ensure the safety of the rail and rail facility, it is extremely important to treat / resolve the cracks that occur at an early stage.

レールにおける既述したすべての欠陥又は変質を排除又は処理可能とする簡便かつ効果的な措置はレールを削磨することである。レールの走行面は、通常、約５／１００mmだけ削磨され、材料変位を調整すると共に、生じた細微な亀裂を平坦に研削する。   A simple and effective measure that makes it possible to eliminate or deal with all the aforementioned defects or alterations in the rail is to sharpen the rail. The running surface of the rail is usually ground by about 5/100 mm to adjust the material displacement and grind the fine cracks that have occurred flatly.

従来技術においては様々な研削方法及び研削装置が公知である。まず、回転駆動される研削部材によって作業を行う装置が公知である。自明のことながら、これらの装置は遅い前進速度でしかレールの加工を可能にしないのが不利である。多くの場合、遅行である。このことが支障であると感じられたため、特許文献１では請求項１の上位概念のすべての特徴を開示した研削装置が提案されている。この装置により、レール加工は、駆動されない研削部材のために約８０〜１２０ｋｍ／ｈの明らかに上昇した速度で実現可能となる。この進歩によりレールの切削加工は経済的なものとなる。 Various grinding methods and grinding apparatuses are known in the prior art. First, an apparatus that performs an operation using a grinding member that is rotationally driven is known. It is self-evident that these devices are disadvantageous in that they only allow the rail to be machined at a slow forward speed. Often slow. Since this was felt to be a hindrance, Patent Document 1 proposes a grinding apparatus that discloses all the features of the superordinate concept of claim 1. With this device, rail machining can be achieved at a clearly increased speed of about 80-120 km / h for non-driven grinding members. This progress makes rail cutting economical.

特許文献１に記載された装置は更に改良の余地を残すのが不利である。研削部材の唯一の具体的な実施形態として図示された形状において、研削面は研削部材の軸線方向で見て凹状を呈する。この形状は、上方走行面を含むレールの全体走行面及び上方走行面に側方で連なる両サイドエッジをオーバーラップする。ここには、開示された方法又は開示された装置の具体的な実施に係る重大な困難が隠されている。ポイント、軌道交差部、類似の軌道構造素子等を通過する際に研削工程は妨げられる。特許文献１に記載されたような形状とする研削部材は、ポイントの通過に際してレール外側（軌道の第２レールの反対側）でサイドエッジをオーバーラップする研削面部分と共にポイント又はタングの中心部に係留する。このことは、研削部材及び／又はポイントの損傷につながる。レールの研削に際して、装置は各ポイント又は類似の軌道構造素子の前で制動され、研削部材はレールから取り外される。加工の遅延に加えて、ポイント及び類似の軌道構造素子におけるレールは研削が不可能となり、上述のすべての不利を有するレール磨耗は排除することができない。
欧州特許第０７０８２０５号明細書 The apparatus described in Patent Document 1 is disadvantageous in that it leaves room for further improvement. In the shape illustrated as the only specific embodiment of the grinding member, the grinding surface is concave when viewed in the axial direction of the grinding member. This shape overlaps both the side edges that are connected laterally to the entire traveling surface of the rail including the upper traveling surface and the upper traveling surface. This hides significant difficulties associated with the specific implementation of the disclosed method or apparatus. The grinding process is hindered when passing through points, track intersections, similar track structure elements, and the like. A grinding member having a shape as described in Patent Document 1 is provided at the center of a point or tongue together with a grinding surface portion that overlaps a side edge outside the rail (opposite the second rail of the track) when the point passes. Moored. This leads to damage of the grinding member and / or points. Upon grinding of the rail, the device is braked in front of each point or similar track structure element and the grinding member is removed from the rail. In addition to machining delays, rails at points and similar track structure elements cannot be ground and rail wear with all the disadvantages described above cannot be eliminated .
European Patent No. 0708205

本発明の課題は、従来技術における装置を改良し、ポイント及び類似の軌道構造素子を同時に加工可能とし、そのために作業速度を著しく低減する必要がないものとする装置を提案することにある。   The object of the present invention is to improve the device in the prior art and to propose a device which makes it possible to work simultaneously with points and similar track structure elements, so that it is not necessary to significantly reduce the working speed.

この課題を解決するため、本発明による装置は、研削フレームには少なくとも２個の研削部材を配置し、第１研削部材のレール加工のための第１研削面がレールの上方走行面のみを研削するために成形した輪郭を具え、第２研削部材のレール加工のための第２研削面がレールの上方走行面及びこの上方走行面に側方で連なる一方のサイドエッジを研削するために成形した輪郭を具えることを特徴とする。 To solve this problem, the device according to the invention, placing at least two grinding members on the grinding frame, the upper side run line surface of the first grinding surface rail for rail working of the first grinding member only It comprises a contour that is shaped to grinding, to a second grinding surface for rail working of the second grinding member for grinding the one side edge continuous with the upper running surface and side to the upper running surface of the rail It is characterized by having a molded contour.

本発明は、１個の車輪によって実際に通過される上方走行面及び必要とあらば車輪によって通過される走行エッジを研削するだけで研削処理は十分であるとの認識に基づくものである。軌道に敷設されたレールの場合、其々に対置するレールに対向するレールのインナーエッジだけを通過すると共に、それに応じて負荷を受ける。それに対して、レールのアウターエッジは、車輪によって通過されると共に、これらのエッジの研削が不必要とする明らかに少ない負荷を受ける。   The invention is based on the recognition that the grinding process is sufficient simply by grinding the upper running surface actually passed by one wheel and, if necessary, the running edge passed by the wheel. In the case of a rail laid on a track, it passes only through the inner edge of the rail facing the rail facing each other and receives a load accordingly. In contrast, the outer edges of the rails are passed by the wheels and are subjected to a distinctly small load that is unnecessary to grind these edges.

レールのアウターエッジに当接する研削面部分は、上記特許文献１に記載された研削部材において、ポイント又は類似の軌道構造素子の通過に際する上述の問題を引き起こす。本発明による各研削部材が具える各研削面は、レールの上方走行面、あるいは、レールの上方走行面に連なるサイドエッジの一方とレールの上方走行面をオーバーラップする輪郭を具える。したがって、ポイントの通過又は類似の軌道構造素子の通過に際する上述の支障を避けると共に、本装置は軌道構造素子を具える領域でも高い前進速度でレールを研削することができる。 The portion of the grinding surface that abuts the outer edge of the rail causes the above-mentioned problems in passing the point or similar track structure element in the grinding member described in the above-mentioned Patent Document 1. Each grinding surface comprising each grinding member according to the present invention, the upper running surface of the rail, or comprises one overlapping contour the upper running surface of the rail of the side edges continuing to the upper running surface of the rail. Thus, while avoiding the above-mentioned obstacles in passing points or similar track structure elements, the device can grind the rails at high forward speeds even in areas comprising track structure elements.

更に、本発明で投入される研削部材は、上記特許文献１に開示された研削部材に比べて、縮小した研削面をより小さい寸法とするのが有利である。研削部材の作製は高価であり、研削部材のサイズが大きくなるにつれ製造コストは増加する。小さな研削部材を使用することにより、製造時のコスト削減が可能となる。研削部材は自明のことながら定期的に補完すべき磨耗部品であるため、小さい研削部材は運用及び管理保全コストの面からも有利である。 Furthermore, it is advantageous for the grinding member introduced in the present invention to have a reduced grinding surface with a smaller size as compared with the grinding member disclosed in Patent Document 1 . The production of the grinding member is expensive and the manufacturing cost increases as the size of the grinding member increases. By using a small grinding member, the manufacturing cost can be reduced. Since the grinding member is a worn part that should be supplemented on a regular basis, it is obvious that a small grinding member is advantageous in terms of operation and management maintenance costs.

少なくとも１個の研削部材は、旋回軸に対して回転対称として形成するのが好適である。   The at least one grinding member is preferably formed rotationally symmetric with respect to the pivot axis.

更に、少なくとも１個の研削部材は、レールの走行面に抗する押圧力の方向で堅固な支持によって選択的にオーバーラップ可能な弾性部材を通じて研削フレームに支持するのが好適である。研削部材の弾性的支持は、上述したレールのうねりの頂上領域において、弾性部材の弾性特性に依存する押圧力の増大を条件とする。したがって、レールの走行面における研削部材の押圧力の自己調節は其々の高さ誤差に応じて行われる。しかしながら、研削部材の待避可能性は必ずしも所望とは限らない。この理由から、弾性部材は選択的に堅固な支持によってオーバーラップ可能となる。   Furthermore, it is preferable that the at least one grinding member is supported on the grinding frame through an elastic member that can be selectively overlapped by a solid support in the direction of the pressing force against the running surface of the rail. The elastic support of the grinding member is conditioned on an increase in the pressing force depending on the elastic characteristics of the elastic member in the above-described top region of the rail swell. Therefore, the self-adjustment of the pressing force of the grinding member on the rail running surface is performed according to the respective height errors. However, the retractability of the grinding member is not always desirable. For this reason, the elastic members can be overlapped by selectively rigid support.

本発明の実施形態において、各研削部材は、レールに同時に着手するために設計される。レールの走行面の特定領域を研削するために特別に形成した２個の研削部材を配置することにより、研削部材は研削面に沿って特に的確に輪郭形成が可能となる。したがって、走行面の其々の領域を可能な限り正確に研削することができる。特に良好な研磨状態が実現し、研削後の極めて良好なレール形状はレールの良好な走行特性と一体化する。更に、研削部材は特に小型かつコンパクトに形成可能であり、既述のコスト的にも有利である。 In implementation of the invention, each abrasive member is designed to undertake the rail at the same time. By arranging two grinding members specially formed for grinding a specific area of the running surface of the rail, the grinding member can be particularly accurately contoured along the grinding surface. Therefore, each region of the running surface can be ground as accurately as possible. Particularly good polishing conditions are realized, and the very good rail shape after grinding is integrated with the good running characteristics of the rail. Furthermore, the grinding member can be formed particularly small and compact, which is advantageous in terms of cost as described above.

レール走行面の個々の領域を研削するために投入された両方の研削部材を形成する場合、第１研削部材は概ね切頭錐体外周形状とする研削部材の軸線方向で僅かに凹状とした第１研削面を具え、第２研削部材は第１部分と第２部分とから構成される第２研削面を具える。第１部分は、概ね切頭錐体外周形状とする研削部材の軸線方向で僅かに凹状を示し、第２部分は第２研削部材の軸線方向で第１部分に隣接する。第２部分では第２研削面が第２研削部材の軸線方向で見て凹状に外方へ湾曲して延在する。 In the case of forming both grinding members supplied for grinding individual regions of the rail running surface, the first grinding member is generally concave in the axial direction of the grinding member having a truncated cone outer peripheral shape . The first grinding surface includes a second grinding surface including a first portion and a second portion. The first portion has a slightly concave shape in the axial direction of the grinding member that is generally truncated cone-shaped, and the second portion is adjacent to the first portion in the axial direction of the second grinding member. In the second portion, the second grinding surface extends outwardly in a concave shape when viewed in the axial direction of the second grinding member.

第１研削部材は、実際には切頭錐体として作製され、レールの上方走行面を研削するために使用される。研削開始によって、第１研削部材の第１研削面に、レールの上方走行面の湾曲に相補的に一致する僅かに凹状とするプロファイルが削入される。このように僅かに凹状とするプロファイルは、第１研削部材の第１研削面で既に作製時に形成可能である。第１研削部材の切頭錐体形状は、この第１研削部材で研削された上方走行面のプロファイルに鑑みて有利であることが実証される。 The first grinding member is actually made as a truncated cone and is used to grind the upper running surface of the rail. By starting the grinding, a slightly concave profile is cut into the first grinding surface of the first grinding member which complementarily matches the curvature of the upper running surface of the rail. Such a slightly concave profile can be formed on the first grinding surface of the first grinding member at the time of production. It is demonstrated that the truncated cone shape of the first grinding member is advantageous in view of the profile of the upper running surface ground with this first grinding member.

第２研削部材は、２部分に分割される第２研削面を具える。第１部分では第２研削部材もまた切頭錐体として成形される。この部分には第２部分が連なり、第２研削部材は凹状で外方に延在する“ネック部”を具える。この第２研削部材の形状により、走行面のエッジ、特に、インナーエッジ又は走行エッジの研削に良好な適性が与えられる。 The second grinding member includes a second grinding surface that is divided into two parts. In the first part, the second grinding member is also shaped as a truncated cone. This part is connected to the second part, and the second grinding member has a “neck part” that is concave and extends outward. The shape of the second grinding member provides good suitability for grinding the edge of the running surface, particularly the inner edge or the running edge.

第１研削部材の場合、第１研削面の軸線方向長さがレールの加工すべき上方走行面の幅に概ね一致するのが有利であるのに対し、第２研削部材の第２研削面の第１部分は、軸線方向において加工すべき上方走行面の幅よりも短いのが好適である。第１研削部材の第１研削面の軸線方向長さは、概ねレールの上方走行面の全幅に及ぶため、上方走行面の全体が第１研削部材によって確実に研削可能となる。殆どレールのインナーエッジだけを研削する第２研削部材については、切頭錐体の部分を短く形成する。それにより、第２研削部材の寸法は縮小され、コスト的にも有利となる。 In the case of the first grinding member, it is advantageous that the axial length of the first grinding surface substantially coincides with the width of the upper running surface to be processed by the rail, whereas the second grinding surface of the second grinding member The first portion is preferably shorter than the width of the upper running surface to be machined in the axial direction. Since the length in the axial direction of the first grinding surface of the first grinding member substantially covers the entire width of the upper traveling surface of the rail, the entire upper traveling surface can be reliably ground by the first grinding member. About the 2nd grinding member which grinds only the inner edge of a rail, the part of a truncated cone is formed short. Thereby, the dimension of the second grinding member is reduced, which is advantageous in terms of cost.

研削フレームには、レール長手方向で見て複数個の研削部材を連続して配置することができる。旋回軸は全体として平行かつレール長手方向に対して鋭角に整列される。このような平行配置は、上記特許文献１の図５に示された公知の成形による研削部材に該当する。この配置により、特にコンパクトな構造が実現する。 A plurality of grinding members can be continuously arranged on the grinding frame when viewed in the rail longitudinal direction. The pivot axes are generally parallel and aligned at an acute angle with respect to the longitudinal direction of the rail. Such parallel arrangement corresponds to the grinding member according to a known molding shown in FIG. 5 of Patent Document 1. This arrangement realizes a particularly compact structure.

研削フレームには代替的にレール長手方向で見て複数個の研削部材を連続して配置することができる。研削部材の旋回軸は概ね水平面内で交互に６０°〜１２０°、好適には約９０°の角度で互いに旋回すると共に、レール長手方向に対して鋭角に整列する。このような配置は、前述のようにコンパクトに構成されていないが、研削の成果に鑑みて有利である。   Alternatively, a plurality of grinding members can be continuously arranged on the grinding frame as viewed in the longitudinal direction of the rail. The pivoting axes of the grinding members pivot in an alternating manner approximately in the horizontal plane at an angle of 60 ° to 120 °, preferably about 90 °, and are aligned at an acute angle with respect to the longitudinal direction of the rail. Such an arrangement is not compact as described above, but is advantageous in view of the results of grinding.

その他の考え得る構造的特徴、即ち、特に目直部材の性状及び配置又は研削部材の制動装置を具える可能性等については、上記特許文献１の記載を参照することができる。そこで開示された構造的措置は、レールに対して傾斜した自由に回転可能な研削部材を具える装置の原理に係るものであり、研削部材の特別な形状によって排除されない限り、本発明においても十分に応用可能とするものである。この意味において、上記特許文献１は本発明の記述に関連している。 For other possible structural features, in particular the properties and arrangement of the straight members or the possibility of having a braking device for the grinding member, reference can be made to the description in the above-mentioned patent document 1 . The structural measures disclosed there relate to the principle of the device comprising a freely rotatable grinding member inclined with respect to the rail and are sufficient in the present invention unless excluded by a special shape of the grinding member. It can be applied to. In this sense, the above-mentioned patent document 1 relates to the description of the present invention.

本発明によれば、ポイントの通過又は類似の軌道構造素子の通過に際する支障を避けると共に、軌道構造素子を具える領域でも高い前進速度でレールを研削することができ、かつ、縮小した研削面をより小さい寸法とすることが可能になり、製造時のコスト削減が可能となる。According to the present invention, it is possible to avoid obstacles when passing points or similar track structure elements, and at the same time, it is possible to grind the rail at a high forward speed even in a region including the track structure elements, and to reduce grinding. The surface can be made smaller in size, and the manufacturing cost can be reduced.

以下、本発明を図示の好適な実施形態について更に具体的に説明する。   Hereinafter, the present invention will be described more specifically with reference to preferred embodiments shown in the drawings.

図１は、本発明による装置の要部を形成する研削部材１０をレール１上に載置した状態として示す見取り図である。図２は、図１に示した配置を上方から見て示す平面図である。研削部材１０は、本発明による研削装置の研削フレーム（図示せず）に旋回軸１１で自由に回転可能として配置され、旋回軸に対して回転対称に構築される。切頭錐体形状とした研削部材１０は、軸線方向に僅かに凹状に湾曲した研削面１２を具える。図示した僅かな凹状湾曲は、既に研削部材１０の作製時に成形可能である。研削部材１０は切頭錐体として作製するのが好適であり、凹状湾曲はレール１の研削加工によって初めて上方の走行面２の湾曲に対する相補的な湾曲として研削面１２に具現化される。研削部材１０の旋回軸１１は水平方向に配置され、レール長手方向５に対して鋭角αに調整される。角度αは、図示の実施形態においては４０°とする。研削部材の直径は２００ｍｍである。   FIG. 1 is a sketch showing a grinding member 10 forming a main part of an apparatus according to the present invention as being placed on a rail 1. FIG. 2 is a plan view showing the arrangement shown in FIG. 1 as viewed from above. The grinding member 10 is disposed on a grinding frame (not shown) of the grinding apparatus according to the present invention so as to be freely rotatable about the pivot axis 11, and is constructed to be rotationally symmetric with respect to the pivot axis. The grinding member 10 having a truncated cone shape includes a grinding surface 12 that is slightly concavely curved in the axial direction. The slight concave curvature shown can already be formed when the grinding member 10 is produced. The grinding member 10 is preferably produced as a truncated cone, and the concave curvature is only embodied on the grinding surface 12 as a complementary curvature to the curvature of the upper running surface 2 by grinding the rail 1. The turning shaft 11 of the grinding member 10 is arranged in the horizontal direction and is adjusted to an acute angle α with respect to the rail longitudinal direction 5. The angle α is 40 ° in the illustrated embodiment. The diameter of the grinding member is 200 mm.

研削部材１０は研削面１２によってレール１の上方の走行面２だけをオーバーラップする。走行面のエッジ３，４は研削部材１０によって捕捉されない。   The grinding member 10 overlaps only the running surface 2 above the rail 1 with the grinding surface 12. The edges 3 and 4 of the running surface are not captured by the grinding member 10.

作動中には自由に回転可能として配置された研削部材１０がレール長手方向５に対する図示の傾斜位置でこの方向に引張される。それにより、欧州特許第０７０８５０２号明細書に記載された原理に従って研削作用が生じる。 During operation, the grinding member 10 arranged to be freely rotatable is pulled in this direction at the inclined position shown with respect to the longitudinal direction 5 of the rail. Thereby, a grinding action occurs according to the principle described in EP 0 708 502 .

図４では、本発明の装置に具えた第２研削部材２０をレール１上に載置した状態として示している。図４は、図３に示した配置を上方から見て示す平面図である。研削部材２０の旋回軸２１もまた本発明による研削装置の研削フレーム（図示せず）に自由に回転可能として配置され、研削部材２０は旋回軸２１に対して回転対称に構築される。研削部材２０は、２部分から構成された研削面２２を具える。第１部分２３では研削面が切頭錐体の外周面に対応する。第２部分２４では研削面が凹状に外方へ湾曲すると共に、研削部材２０のネック部２５を形成する。作動中の研削部材２０はネック部２５によってレール１のインナーエッジ３を包囲し、これを研削する。研削部材２０の旋回軸２１は水平方向に配置されると共に、レール長手方向５に対して鋭角αだけ調整される。角度αは図示の実施例では７２°、研削部材の直径は２００ｍｍとする。 In FIG. 4 , the second grinding member 20 provided in the apparatus of the present invention is shown as being placed on the rail 1. FIG. 4 is a plan view showing the arrangement shown in FIG. 3 as viewed from above. The turning shaft 21 of the grinding member 20 is also arranged to be freely rotatable on a grinding frame (not shown) of the grinding apparatus according to the present invention, and the grinding member 20 is constructed rotationally symmetrically with respect to the turning shaft 21. The grinding member 20 comprises a grinding surface 22 composed of two parts. In the first portion 23, the grinding surface corresponds to the outer peripheral surface of the truncated cone. In the second portion 24, the grinding surface is curved outward in a concave shape, and the neck portion 25 of the grinding member 20 is formed. The grinding member 20 in operation surrounds the inner edge 3 of the rail 1 by the neck portion 25 and grinds it. The turning shaft 21 of the grinding member 20 is arranged in the horizontal direction and is adjusted by an acute angle α with respect to the rail longitudinal direction 5. In the illustrated embodiment, the angle α is 72 °, and the diameter of the grinding member is 200 mm.

自由に回転可能として配置された研削部材２０もまた作動中は図示のレール長手方向５に対する傾斜位置でこの方向に引張される。それにより、欧州特許第０７０８５０２号明細書に記載された原理に従って研削作用が研削部材２０についても生じる。 The grinding member 20 arranged as freely rotatable is also pulled in this direction at an inclined position relative to the rail longitudinal direction 5 shown in operation. Thereby, a grinding action also occurs on the grinding member 20 in accordance with the principle described in EP 0708502 .

本発明による装置において、其々に複数個の研削部材１０，２０をレール長手方向でレール１に対して鋭角に連続して配置し、１個のユニットに統合する。装置を適切に形成することにより、成形の異なる研削部材１０，２０は走行面の異なる領域を加工するために、同時に一本のレールで着手可能となる。更に、本発明の装置は軌道の両方のレールを同時に加工するための平行に配置したユニットを具えることができる。研削部材１０，２０は、欧州特許第０７０８５０２号明細書に記載された実施形態と同様、既知の幾何学的配置とする研削部材によって示したように配置可能である。これらの研削部材は，其々に６０°〜１２０°、好適には約９０°の角度だけ水平方向の面内で互いに転向した旋回軸１１，２１に配置することができる。 In the apparatus according to the present invention, a plurality of grinding members 10 and 20 are continuously arranged at an acute angle with respect to the rail 1 in the longitudinal direction of the rail, and are integrated into one unit. By appropriately forming the device, the grinding members 10 and 20 having different shapes can be simultaneously started with one rail in order to process different regions of the running surface. Furthermore, the device according to the invention can comprise units arranged in parallel for machining both rails of the track simultaneously. The grinding members 10, 20 can be arranged as shown by the grinding members having a known geometric arrangement, similar to the embodiment described in EP 0708502 . These grinding members can be arranged on pivot shafts 11 and 21 which are mutually turned in a horizontal plane by an angle of 60 ° to 120 °, preferably about 90 °.

図１〜４に示した両方の研削部材１０，２０を具える本発明の装置により、レール１の上方の走行面２及びインナーエッジ３を研削加工するが、アウターエッジ４は加工されない。このことは、本発明の基礎となる重要な認識に鑑みても不必要である。アウターエッジ４の領域では何れの研削部材１０，２０もレール１の走行面から突出しないため、ポイント又は類似の軌道構造素子の通過に際しても前述の問題はもはや生じない。   1-4, the running surface 2 and the inner edge 3 above the rail 1 are ground by the apparatus of the present invention including both the grinding members 10 and 20 shown in FIGS. This is unnecessary even in view of the important recognition underlying the present invention. In the region of the outer edge 4, no grinding members 10, 20 protrude from the running surface of the rail 1, so that the aforementioned problems no longer occur when passing points or similar track structure elements.
