Vorrichtung zum Schleifen von SchienenDevice for grinding rails
Die Erfindung bezieht sich auf eine Vorrichung zum Schleifen von Schienen, insbesondere Schienenstößen, mit einer an das Schienenprofil heranführbaren, in einem Schleifscheibenträger gehaltenen Schleif¬ scheibe, wobei der Schleifscheibenträger beidseits der Schleif stelle an der Schiene abgestützt ist.The invention relates to a device for grinding rails, in particular rail joints, with a grinding wheel which can be brought up to the rail profile and is held in a grinding wheel carrier, the grinding wheel carrier being supported on the rail on both sides of the grinding point.
Bei bekannten Vorrichtungen dieser Art ist der Schleifscheiben¬ träger auf einem auf der Schiene verfahrbaren Gestell angeordnet, wobei die Rollen dieses Gestelles auch dessen Verschwenkung erlauben. Die Schleif scheibenachse verläuft etwa quer zur Schienenlängsachse und die von einem Verbrennungsmotor angetriebene Schleifscheibe ist in Richtung zur Schiene hin von Hand aus bewegbar. Der Bedienende führt und schwenkt das Gestell beim Schleifen entsprechend seinem Gefühl , wobei zwischendurch Messungen vorgenorrrnen werden. Es ist klar, daß eine solche Vorrichtung Spezialisten zur Bedienung benötigt und trotzdem die Ergebnisse sehr oft unbefriedigend sind.In known devices of this type, the grinding wheel carrier is arranged on a frame which can be moved on the rail, the rollers of this frame also allowing its pivoting. The grinding wheel axis runs approximately transverse to the longitudinal axis of the rail and the grinding wheel driven by an internal combustion engine can be moved in the direction of the rail by hand. The operator guides and swivels the frame when grinding according to his feeling, with measurements being pre-torn in between. It is clear that such a device requires specialists to operate, and yet the results are very often unsatisfactory.
Die vorliegende Erfindung hat es sich zum Ziel gesetzt, eine Vorrichtung zu schaffen, mit der mit weniger gut geschulten Arbeits¬ kräften eine Schiene schneller und gleichmäßiger als bisher zu schleifen ist. Erreicht wird dies im wesentlichen dadurch, daß der Schleifscheibenträger an zwei beidseits der Schleifstelle befindlichenThe present invention has set itself the goal of creating a device with which a rail can be ground faster and more uniformly than previously with less well-trained workers. This is essentially achieved in that the grinding wheel carrier is located on two sides of the grinding point
Punkten je einerseits in einer zum Idealprofil der Schiene im wesentlichen parallel verlaufenden Kurvenbahn geführt und anderseits im gleichen Abstand vom tatsächlichen Schienenprofil gehalten ist.Points are each guided in a curved path that is essentially parallel to the ideal profile of the rail and is kept at the same distance from the actual rail profile.
Durch die erf indungsgerräßen Maßnahmen wird bewirkt, daß einerseits die Radien des Idealprofiles, anderseits der tatsächliche Zustand auf beiden Seiten der Schleifstelle berücksichtigt werden. Es korrmt daher auch bei Schienenstößen, bei denen zwei unterschiedlich abgenützte Schienen aneinander stoßen, zu einem gleichmäßigen Übergang. Die Gleichmäßigkeit des Überganges ist aber besonders wichtig, weil Stöße auf die Räder des darüber fahrenden Zuges, insbesondere bei den irrmer höher werdenden Geschwindigkeiten, vermieden werden sollen. Eine besonders kompakte und in sich steife Vorrichtung ergibt sich, wenn die Kurvenbahnen zur Führung des Schleif Scheibenträgers an den Stehern eines Portal rahmens angeordnet sind.The measures according to the invention have the effect that on the one hand the radii of the ideal profile and on the other hand the actual state on both sides of the grinding point are taken into account. It therefore correlates to a smooth transition even in the case of rail joints where two differently worn rails meet. The smoothness of the transition is particularly important, however, because bumps on the wheels of the train traveling above it, particularly at the increasingly high speeds, should be avoided. A particularly compact and inherently rigid device results if the cam tracks for guiding the grinding wheel carrier are arranged on the uprights of a portal frame.
Die Verschiebung der Schleifscheibenträger in den Kurvenbahnen kann von Hand aus erfolgen, zweckmäßig ist jedoch der Schleifscheiben¬ träger in seinen beidseitig angeordneten Kurvenbahnen motorisch verschiebbar.The grinding wheel carrier in the cam tracks can be moved by hand, but the grinding wheel carrier in its cam tracks arranged on both sides is expediently movable by motor.
Bei einer bevorzugten Ausführungsform der Erfindung erfolgt die Führung des Schleif Scheibenträgers in den Kurvenbahnen über je zwei bcmbierte Rollen und an den zugehörigen Rollenträgem greift jedes Ende eines über Umlenkrollen geführten Zugorganes an. Die Bombierung der Rollen ermöglicht ein Schwenken des Schleif Scheibenträgers in bezug auf die Schienenlängsachse in jenen Fällen, in denen beidseits der Schleif stelle verschieden abgenützte Schienen vorhanden sind. Durch die Verwendung von zwei Rollen wird auf einfache V/eise erreicht, daß die Achse der Schleifscheibe im wesentlichen irrmer zum Mittelpunkt des jeweiligen Radius des Idealprofiles hinweist.In a preferred embodiment of the invention, the grinding wheel carrier is guided in the cam tracks by means of two bracketed rollers and each end of a pulling element guided by deflection rollers engages the associated roller carriers. The crowning of the rollers enables the grinding wheel carrier to be pivoted with respect to the longitudinal axis of the rail in those cases in which differently worn rails are present on both sides of the grinding point. By using two rollers it is achieved in a simple manner that the axis of the grinding wheel points essentially erroneously to the center of the respective radius of the ideal profile.
Die Verwendung eines an den Rollenträgem angreifenden Zugorganes, das bei einer zweckmäßigen Ausführungsform als Zahnriemen ausgebildet ist, ermöglicht auf einfache Weise die Bewegung des Schleifscheiben- trägers in den Kurvenbahnen.The use of a pulling element engaging the roller carrier, which in the case of an expedient embodiment is designed as a toothed belt, enables the movement of the grinding wheel carrier in the cam tracks in a simple manner.
Zur Synchronisation der Bewegung in beiden Kurvenbahnen sind zweckmäßig zwei gegenüberliegende Umlenkrollen über eine Welle mit¬ einander verbunden. Eine mögliche Bewegung des Schleif Scheibenträgers in alle Richtun¬ gen wird erreicht, wenn der Schleifscheiben träger an Längsführungen verschiebbar geführt ist, die Längsführungen an ihren beiden Enden in Querführungen verschiebbar sind und die Querführungen in den Kurven¬ bahnen geführt sind. Zur Einhaltung des gleichen Abstandes vom tatsächlichen Schienen¬ profil ist dabei beidseits der Längsführungen je eine auf der Schiene aufliegende Rolle vorgesehen. Eine sichere und einfach zu handhabende Abstützung der Vorrichtung wird nach einem weiteren Merkmal der Erfindung dadurch erreicht, daß beidseitig je ein leicht koni scher, die Schiene seitlich umfassender Sitz vorgesehen ist, dem zwei relativ zueinander zangenartig bewegbare Arme zugeordnet sind, die an der Unterseite des Schienenkσpfes angreifen.To synchronize the movement in both cam tracks, two opposite deflection rollers are expediently connected to one another via a shaft. A possible movement of the grinding wheel carrier in all directions is achieved if the grinding wheel carrier is guided displaceably on longitudinal guides, the longitudinal guides are displaceable in transverse guides at their two ends and the transverse guides are guided in the curved tracks. In order to maintain the same distance from the actual rail profile, a roller resting on the rail is provided on both sides of the longitudinal guides. A safe and easy-to-use support of the device is achieved according to a further feature of the invention in that a slightly conical shear, the rail laterally comprehensive seat is provided on both sides, the two relatively movable tong-like arms are assigned to the underside of the Attack the rail head.

In order to be able to transport the processing point easily, rollers can be placed on the rail, by means of which the device can be moved on the rail.
Im Gegensatz zu den bekannten Vorrichtungen ist vorteilhaft zum Antrieb der Schleifscheibe ein Elektromotor vorgesehen. Ein solcher Motor hat weit weniger Vibrationen als ein Verbrennungsmotor, sodaß auch dadurch das Arbeitsergebnis günstig beeinflußt wird. Die Regel- und Steuereinrichtung der Vorrichtung sind zweckmäßig im waagrechten Holm des Portalrahmens angeordnet. Dort sind sie einerseits geschützt, anderseits aber leicht zugänglich.In contrast to the known devices, an electric motor is advantageously provided for driving the grinding wheel. Such an engine has far fewer vibrations than an internal combustion engine, so that the work result is also influenced favorably. The regulating and control device of the device are expediently arranged in the horizontal spar of the portal frame. There they are protected on the one hand, but easily accessible on the other hand.

Dabei zeigen: Fig.l die Ansicht einer auf eine Schiene aufgesetzten Vorrichtung quer zur Schienenlängs¬ achse, Fig.2 in einem gegenüber der Fig.l vergrößertem Maßstab eine Ansicht in Schienenlängsrichtung, Fig.3 ebenfalls in vergrößertem Maßstab einen Schnitt längs der Linie I II— II 1 in Fig.l und Fig.4 der. Bereich IV in Fig.l in stark vergrößertem Maßstab.The invention is described in more detail below on the basis of an exemplary embodiment shown in the drawings, but without being restricted to this example. 1 shows a view of a device placed on a rail transversely to the longitudinal axis of the rail, FIG. 2 shows a view in the longitudinal direction of the rail on an enlarged scale compared to FIG. 1, FIG. 3 also shows a section along the line I on an enlarged scale II— II 1 in Fig.l and Fig.4 the. Area IV in Fig.l on a greatly enlarged scale.
Ein Schleifscheibenträger 1 trägt eine von einem Elektromotor angetriebene topfförrnige Schleifscheibe 3, deren Achse unter einem etwas von 90 abweichenden Winkel zur Längsachse der Schiene 5 weist. Die Schiene 5 wird somit an der Stelle 6 geschliffen. Über ein Handrad 7 cd.dgl. ist die Schleifscheibe 3 in Richtung ihrer Achse L bewegbar. Der Schleifscheibenträger 1 ist in Längsführungen 8 längs der Schiene 5 verschiebbar. Im gezeichneten Beispiel weisen die Längsführungen 8 vier Führungsstangen 9 sowie zwei damit verbundene seitliche Abdeckplatten 10 auf. An beiden Enden der Abdeckplatten 10 sind Endplatten 11 angeordnet, die mit Lagern 12 versehen sind.A grinding wheel carrier 1 carries a cup-shaped grinding wheel 3 which is driven by an electric motor and whose axis points at an angle deviating from 90 to the longitudinal axis of the rail 5. The rail 5 is thus ground at point 6. About a handwheel 7 cdgl. the grinding wheel 3 is movable in the direction of its axis L. The grinding wheel carrier 1 is displaceable in the longitudinal guides 8 along the rail 5. In the example shown, the longitudinal guides 8 have four guide rods 9 and two side cover plates 10 connected to them. End plates 11, which are provided with bearings 12, are arranged at both ends of the cover plates 10.
Die Lager 12 umfassen Querführungen 13, die von einer Platte 14 gehalten sind.The bearings 12 include transverse guides 13 which are held by a plate 14.
An einem Fortsatz 15 jeder Endplatte 11 ist eine Rolle 16 gelagert. Beide Rollen 16 liegen auf der Schiene 5 auf. Auf jeder Platte 14 sind zwei bombierte Rollen 17 gelagert, die in Führungen 18 abrollen. Die Führungen 18 verlaufen parallel zum Idealprofil der Schiene 5, d.h. die Mittelpunkte der Krümmungs¬ radien des Schienenprofil es und der Kurvenbahn fallen zumindestens im wesentlichen zusarrmen. Die als Rollenträger wirkende Platte 14 ist mit Zapfen 19 versehen, an denen je das Ende eines Zahnriemens 20 angreift, der über Umlenkrollen 21 geführt ist. Eine Gelenkwelle 22, die über einen Motor 23 drehbar ist, verbindet die beiden obersten gegenüber- 1 i eg enden Uml enk rol 1 en 21. Die Kurvenbahnen 18 sind in den Stehern 24 eines Portal rahmens vorgesehen, dessen waagrechter Holm 25 einerseits die Stabilität der Vorrichtung gewährleistet, anderseits den Motor 23, die Welle 22 sowie die Steuer- und Regeleinrichtungen 26 der Vorrichtung aufnimmt . Zur Festlegung der Vorrichtung an der Schiene 5 ist beidseit g je ein leicht konischer, die Schiene 5 seitlich umfassender Sitz 27 vorgesehen, diesem Sitz 27 sind zwei zueinander zangenartig bewegbare Arme 28 zugeordnet, die an der Unterseite des Schienenkσpfes (Fig.2) angreifen. Die Bewegung der Arme 28 erfolgt über einen Spindel- trieb 29- Um die Vorrichtung auf der Schiene von Bearbeitungsstelle zu Bearbeitungsstelle verfahren zu können, sind an den Stehern 24 Arme 30 angelenkt, die an ihrem einen Ende eine Schienenrolle 31 tragen. Soll die Vorrichtung auf der Schiene verfahren werden, werden die Arme 30 zu den Stehern 24 hin verschwenkt, sodaß die Vorrichtung von der Schiene abgehoben wird und die gesamte Vorrichtung verfahren werden kann. Die Arme 30 werden dabei mit Ansätzen 32 des Portalrahmens verriegelt.A roller 16 is mounted on an extension 15 of each end plate 11. Both rollers 16 rest on the rail 5. Two cambered rollers 17 are mounted on each plate 14, which roll in guides 18. The guides 18 run parallel to the ideal profile of the rail 5, ie the centers of the radii of curvature of the rail profile and the curved path at least essentially coincide. The plate 14 acting as a roller carrier is provided with pins 19, each of which engages the end of a toothed belt 20 which is guided over deflection rollers 21. An articulated shaft 22, which is rotatable via a motor 23, connects the two uppermost opposing Uml enk rol 1 s 21. The cam tracks 18 are provided in the uprights 24 of a portal frame, the horizontal spar 25 on the one hand, the stability of the Device ensures, on the other hand, the motor 23, the shaft 22 and the control devices 26 of the device. To fix the device on the rail 5, a slightly conical seat 27 is provided on both sides of the rail 5, this seat 27 is assigned two arms 28, which can be moved like forceps and which engage on the underside of the rail head (FIG. 2). The arms 28 are moved via a spindle drive 29. In order to be able to move the device on the rail from processing point to processing point, arms 30 are articulated on the uprights 24, which carry a rail roller 31 at one end. If the device is to be moved on the rail, the arms 30 are pivoted towards the uprights 24, so that the device is lifted off the rail and the entire device can be moved. The arms 30 are locked with lugs 32 of the portal frame.

Schleif stelle 6 durch Aufsetzen auf den Sitz 27 und Verschwenken der Arme 28 festgelegt und der Schleifscheibenträger 1 von Hand aus oder motorisch (nicht dargestellt) längs der Schiene verschoben. Von Zeit zu Zeit wird dann durch Betätigen des Motors 23 der Zahn- riemen 20 bewegt und damit der Schleifscheibenträger 1 entlang der Kurvenbahn 18 verschwenkt. Dabei liegen jedoch die Rollen 16 zufolge der möglichen Führung in den Querführungen 13 jederzeit auf dem tatsächlicher. Profil der Schiene 5 auf. Es kann somit ein stufenloser Übergang zwischen dem Schienenprofil links und dem Schienenprofil rechts der jeweiligen Bearbeitungsstelle 6 geschaffen werden, wobei zufolge der Kurvenbahn 18 eine weitgehende Annäherung an das ideale Schiener rofil möglich ist. Grinding point 6 fixed by placing on the seat 27 and pivoting the arms 28 and the grinding wheel carrier 1 moved by hand or by motor (not shown) along the rail. From time to time, the toothed belt 20 is then moved by actuating the motor 23 and the grinding wheel carrier 1 is thus pivoted along the curved path 18. However, according to the possible guidance in the transverse guides 13, the rollers 16 are always on the actual one. Profile of the rail 5 on. It is thus possible to create a continuous transition between the rail profile on the left and the rail profile on the right of the respective processing point 6, whereby, as a result of the curved path 18, an extensive approximation to the ideal rail profile is possible.
