Description

Die Erfindung bezieht sich auf eine Vorrichtung entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.

Eine zur Bearbeitung von Schienenverbindungen, hier zum Entfernen von Schweißgutüberständen bestimmte Vorrichtung ist beispielsweise aus der WO 2011/059395 A1 bekannt. Hierbei ist ein, ein Schleifwerkzeug mit einem Antrieb tragender innerer Rahmen um eine sich achsparallel zu der zu behandelnden Schienenverbindung erstreckende Achse in einem äußeren Rahmen schwenkbar gehalten. Die so definierte Schwenkachse befindet sich oberhalb des Schienenkopfes der Schienenverbindung. Der äußere Rahmen ist über Stützrollen am Schienenkopfbereich der einen der beiden Schienen eines Gleises abgestützt und entlang der Schienenverbindung bewegbar. In einer Ebene senkrecht zu der Längsrichtung der Schienenverbindung, und zwar entlang einer halbkreisförmigen, mit dem äußeren Rahmen in fester Verbindung stehenden Führung ist eine rotatorische Zustellbewegung des durch den inneren Rahmen getragenen Schleifwerkzeugs eingerichtet. Das Schleifwerkzeug ist ferner in Richtung auf das Schienenprofil hin zustellbar angeordnet, wobei sämtliche dieser Zustellbewegungen numerisch steuerbar sind. Weitere Zustellbewegungen sind nicht vorgesehen. Als nicht optimal ist bei dieser Vorrichtung das beispielhaft gezeigte zylindrische Schleifwerkzeug in Verbindung mit den offenbarten Zustellbewegungen anzusehen, so dass nicht immer eine an sich erwünschte größtmögliche Anlagefläche an dem zu bearbeitenden Schienenprofil darstellbar ist. Zur Darstellung einer stabilen Position der Vorrichtung während eines Bearbeitungsvorgangs ist ein vergleichsweise kompliziertes System von Stützrollen erforderlich, welche den Schienenkopf zum Teil untergreifen. Schließlich sind zur Darstellung der rotatorischen Zustellbewegung relativ umfangreiche Massen, nämlich der komplette innere Rahmen zu bewegen.A device intended for processing rail connections, here for removing excess weld metal, is, for example, from the WO 2011/059395 A1 known. Here, an inner frame carrying a grinding tool with a drive is held pivotably in an outer frame about an axis that extends axially parallel to the rail connection to be treated. The pivot axis defined in this way is located above the rail head of the rail connection. The outer frame is supported by support rollers on the rail head area of one of the two rails of a track and can be moved along the rail connection. In a plane perpendicular to the longitudinal direction of the rail connection, namely along a semicircular guide that is firmly connected to the outer frame, a rotary feed movement of the grinding tool carried by the inner frame is set up. The grinding tool is also arranged to be adjustable in the direction of the rail profile, with all of these delivery movements being numerically controllable. No further delivery movements are planned. In this device, the cylindrical grinding tool shown as an example in conjunction with the disclosed feed movements is not to be considered optimal, so that the largest possible contact surface on the rail profile to be machined, which is desired, cannot always be represented. To ensure a stable position of the device during a machining process, a comparatively complicated system of support rollers is required, some of which reach under the rail head. Finally, relatively extensive masses, namely the entire inner frame, have to be moved to represent the rotational feed movement.

Eine weitere vergleichbare, ebenfalls zum Bearbeiten eines Schienenkopfprofils bestimmte Vorrichtung ist in dem AT 13916 U1 beschrieben. Hierbei ist ein äußeres, auf den seitlich einander gegenüberliegenden Schienen eines Gleises in deren Längsrichtung verfahrbar angeordnetes Rahmengestell vorgesehen, in dem das Schleifwerkzeug vertikal und horizontal, nämlich in Richtung auf den zu bearbeitenden Schienenkopf hin zustellbar angeordnet ist. Darüber hinaus ist eine weitere Zustellbewegung entlang bogenförmiger Schlitze in einer Horizontalebene eingerichtet. Die Zustellbewegungen sind durch Spindeltriebe gekennzeichnet und manuell bewirkbar. Für die technische Darstellung dieser Zustellbewegungen wird jedoch ein beträchtliches Bauvolumen benötigt, bedingt u. a. durch lange Spindeln, um die benötigten Bewegungsbereiche bereit stellen zu können.Another comparable device, also intended for processing a rail head profile, is in the AT 13916 U1 described. Here, an outer frame is provided, which is arranged on the laterally opposite rails of a track in the longitudinal direction and in which the grinding tool can be moved vertically and horizontally, namely in the direction of the rail head to be machined. In addition, a further feed movement is set up along arcuate slots in a horizontal plane. The feed movements are characterized by spindle drives and can be carried out manually. However, a considerable construction volume is required for the technical representation of these feed movements, due, among other things, to long spindles in order to be able to provide the required ranges of movement.

Die aus diesem Stand der Technik ersichtlichen Zustellbewegungen der Bearbeitungswerkzeuge sind nicht als optimal anzusehen, da eine größtmögliche Anlagefläche des Werkzeugs an der zu bearbeitenden Schienenoberfläche im Bereich des Schienenkopfes nicht in allen Fällen gegeben ist, zumindest verbesserungsbedürftig erscheint.The feed movements of the processing tools evident from this prior art are not to be viewed as optimal, since the largest possible contact surface of the tool on the rail surface to be processed in the area of the rail head is not available in all cases, or at least appears to be in need of improvement.

Eine weitere vergleichbare Vorrichtung ist aus der US-A-5,359,815 bekannt und besteht aus einem äußeren, beidseitig auf die zu bearbeitenden Schienen aufsetzbaren Rahmen, in dem ein Werkzeug zwecks Bearbeitung der Schienen zustellbar gehalten ist. Die eingerichteten Zustellbewegungen bestehen aus einer ersten translatorischen Bewegung in Längsrichtung der Schienen, einer zweiten translatorischen Bewegung in einer Horizontalebene und einer Rotationsbewegung um eine sich parallel zu der Schienenlängsrichtung erstreckende Achse. Zur Darstellung der ersten translatorischen Bewegung ist ein innerer, relativ zu dem äußeren Rahmen in Längsrichtung der Schienen verschiebbarer Rahmen vorgesehen, wobei zur Darstellung der zweiten translatorischen Bewegung ein Stützrahmen zwischen der rechten und der linken Seite der Vorrichtung verschiebbar ist, und zwar mit dem Ziel, eine beidseitige Bearbeitung der Schienen zu ermöglichen. Zur Darstellung der genannten Rotationsbewegung ist der innere Rahmen um eine sich parallel zu der Schienenlängsrichtung orientierte Achse bewegbar. Diese Ausführung der Vorrichtung insbesondere der genannten Zustellbewegungen ist durch einen vergleichsweise komplexen Aufbau gekennzeichnet, wobei zur Darstellung der Zustellbewegungen relativ große Massen zu bewegen sind.Another comparable device is from the US-A-5,359,815 known and consists of an outer frame that can be placed on both sides of the rails to be processed, in which a tool is held in an adjustable manner for processing the rails. The set-up feed movements consist of a first translational movement in the longitudinal direction of the rails, a second translational movement in a horizontal plane and a rotational movement about an axis extending parallel to the longitudinal direction of the rails. To represent the first translational movement, an inner frame which can be displaced relative to the outer frame in the longitudinal direction of the rails is provided, with a support frame being displaceable between the right and left sides of the device to represent the second translational movement, with the aim of to enable the rails to be processed on both sides. To represent the rotational movement mentioned, the inner frame can be moved about an axis oriented parallel to the longitudinal direction of the rail. This version of the device, in particular the delivery movements mentioned, is through one comparatively complex structure, with relatively large masses having to be moved to represent the delivery movements.

Aus der CN-A-108532387 ist eine gattungsgemäße Vorrichtung zum Bearbeiten Schienen bekannt, die einen, zum beidseitigen Aufsetzen auf die Schienen bestimmten äußeren Rahmen aufweist, in dem ein Träger quer zur Längserstreckung der Schienen gleitfähig gelagert ist. Auf dem Träger befindet sich ein, ein Werkzeug tragender Werkzeugschlitten, der zwischen zwei kreisbogenförmigen Führungen angeordnet und entlang derselben bewegbar ist, hierbei eine Schwenkung des Werkzeugs um eine sich parallel zu der Längserstreckung der Schienen verlaufende Achse ermöglichend. Das Werkzeug wird in einer Trägerstruktur gehalten, die in Richtung der Längsachse des Werkzeugs verschiebbar ist. Für die Verschiebung des Trägers quer zu der Längserstreckung der Schienen, des Werkzeugs in Richtung seiner Längsachse und die Schwenkung des Werkzeugs um die sich parallel zu der Längserstreckung der Schienen verlaufende Achse sind jeweils manuell zu betätigende Gewindespindeln einbeziehende Einrichtungen vorgesehen.From the CN-A-108532387 a generic device for processing rails is known, which has an outer frame intended for placement on both sides of the rails, in which a carrier is slidably mounted transversely to the longitudinal extent of the rails. On the carrier there is a tool carriage carrying a tool, which is arranged between two circular arc-shaped guides and can be moved along them, thereby enabling the tool to be pivoted about an axis running parallel to the longitudinal extent of the rails. The tool is held in a support structure that is displaceable in the direction of the longitudinal axis of the tool. For the displacement of the carrier transversely to the longitudinal extent of the rails, of the tool in the direction of its longitudinal axis and the pivoting of the tool about the axis running parallel to the longitudinal extent of the rails, devices including manually operated threaded spindles are provided.

Es ist vor diesem Hintergrund die Aufgabe der Erfindung, eine Vorrichtung der eingangs bezeichneten Art zu entwerfen, welche einen größtmöglichen Bewegungsraum eines beispielsweise zylindrischen Schleifwerkzeugs eröffnet, und damit insbesondere eine optimale Positionierung am Schienenkopf erlaubt. Gelöst ist diese Aufgabe bei einer solchen Vorrichtung durch die Merkmale des Kennzeichnungsteils des Anspruchs 1.Against this background, it is the object of the invention to design a device of the type described at the outset, which opens up the greatest possible movement space of, for example, a cylindrical grinding tool, and thus in particular allows optimal positioning on the rail head. This task is solved in such a device by the features of the characterizing part of claim 1.

Erfindungswesentlich ist hierbei die technische Darstellung der Zustellbewegungen, welche mit dem Ziel erfolgt ist, stabile und höchst präzise Bewegungen zu generieren. Der rahmenartige, zur Darstellung einer translatorischen horizontalen Bewegung eingerichtete Träger kann schubladenartig ausgebildet und beidseitig spielarm bzw. spielfrei in besonderen Führungen des äußeren Rahmens gelagert sein. Auf diese Weise ist eine sehr genaue Führung des Trägers und damit dieser horizontalen Zustellbewegung gegeben. Zur Darstellung der rotatorischen Bewegung sind zwei voneinander beabstandete kreisbogenförmige Führungen auf dem Träger vorgesehen, durch die der Werkzeugschlitten und damit das von diesem getragene Werkzeug auch für diese Bewegungskomponente eine sehr genaue und belastbare Führung erfährt.What is essential to the invention is the technical representation of the delivery movements, which is done with the aim of generating stable and highly precise movements. The frame-like carrier, which is designed to represent a translatory horizontal movement, can be designed like a drawer and stored on both sides with little or no play in special guides of the outer frame be. In this way, very precise guidance of the carrier and thus this horizontal feed movement is ensured. To represent the rotational movement, two spaced-apart circular arc-shaped guides are provided on the carrier, through which the tool slide and thus the tool carried by it also receives very precise and resilient guidance for this movement component.

Der Werkzeugschlitten ist zwischen den genannten Führungen angeordnet. Dies ermöglicht eine symmetrische Übertragung der aus dem Bearbeitungsprozess entstehenden Reaktionskräfte auf den Träger und damit den äußeren Rahmen.The tool slide is arranged between the guides mentioned. This enables a symmetrical transfer of the reaction forces resulting from the machining process to the carrier and thus to the outer frame.

Auf dem Werkzeugschlitten ist eine verschiebbare Trägerstruktur vorgesehen, welche beidseitig schubladenartig geführt werden kann und als Träger des Werkzeugs ausgestaltet ist. Auch für diese Zustellbewegung ist somit eine präzise Führung eingerichtet.A displaceable support structure is provided on the tool carriage, which can be guided like a drawer on both sides and is designed as a support for the tool. Precise guidance is also set up for this delivery movement.

Auf den kreisbogenförmigen Führungen ist in jedem Fall ein ortsfestes Verzahnungsprofil angeordnet, welches mit einem antreibbaren Zahnrad im Eingriff steht. Entsprechend den Merkmalen des Anspruchs 2 ist das Verzahnungsprofil durch eine fest angeordnete Rollenkette dargestellt, wobei das mit dieser im Eingriff stehende Zahnrad durch ein Kettenrad dargestellt.In any case, a stationary toothing profile is arranged on the circular arc-shaped guides, which engages with a drivable gear. According to the features of claim 2, the toothing profile is represented by a fixed roller chain, the gear wheel in engagement with this being represented by a chain wheel.

Die Bremsvorrichtung gemäß den Merkmalen des Anspruchs 3 dient der Sicherung der Arbeitsposition des Werkzeugschlittens während der Bearbeitung eines Schienenkopfprofils.The braking device according to the features of claim 3 serves to secure the working position of the tool slide while machining a rail head profile.

Der genannte äußere Rahmen ist über Laufräder auf den Schienen aufgelagert. Zweckmäßigerweise sind die Laufräder mit einer Feststellbremse ausgerüstet, um die Position der Vorrichtung in der Bearbeitungsstellung zu sichern.The outer frame mentioned is supported on the rails via wheels. The wheels are expediently equipped with a parking brake to secure the position of the device in the processing position.

Man erkennt anhand der vorstehenden Ausführungen, dass mit der erfindungsgemäßen Vorrichtung ein Gerät zur Verfügung gestellt wird, welches neben einer genauen Ausrichtung der Zustellbewegungen vielseitige Anpassungsmöglichkeiten an ein zu bearbeitendes Schienenkopfprofil, eine hohe Abdeckung des Profils und somit ein effizientes Reprofilieren ermöglicht.It can be seen from the above statements that the device according to the invention provides a device which, in addition to precise alignment of the feed movements, enables versatile adaptation options to a rail head profile to be processed, high coverage of the profile and thus efficient reprofiling.

Mit 1 ist in Fig. 1 ein Gleis bezeichnet, auf dessen Schienen 2, 3 die Vorrichtung über Laufräder 4 beidseitig aufgelagert ist. Die Vorrichtung besteht aus einem in etwa rechteckigen äußeren Rahmen 7, an dessen vier Ecken die Laufräder 4 jeweils gelagert sind.With 1 is in Fig. 1 denotes a track, on the rails 2, 3 of which the device is supported on both sides via wheels 4. The device consists of an approximately rectangular outer frame 7, at the four corners of which the wheels 4 are each mounted.

In dem Rahmen 7, in einer Richtung der Pfeile 5 quer zu der Längserstreckung der Schienen 2, 3 ist ein schubladenartiger Träger 6 horizontal verschiebbar aufgenommen. Der in der Draufsicht global rechteckige Träger 6 ist beidseitig in dem Rahmen 7 gelagert und erfährt auf diese Weise eine genaue und beanspruchungsgerechte Führung. Der Träger 6 ist - quer zu der Längsrichtung der Schienen 2, 3 in deren Längsrichtung beabstandet - mit zwei kreisbogenartigen Führungen 8, 9 versehen, die sich parallel zueinander in vertikalen Ebenen erstrecken und jeweils der Lagerung einer Rollenkette 10, 11 dienen.In the frame 7, in a direction of the arrows 5 transverse to the longitudinal extent of the rails 2, 3, a drawer-like support 6 is accommodated so that it can be moved horizontally. The carrier 6, which is globally rectangular in plan view, is in the on both sides Frame 7 stored and in this way experiences precise and stress-appropriate guidance. The carrier 6 is - spaced transversely to the longitudinal direction of the rails 2, 3 in their longitudinal direction - provided with two circular arc-like guides 8, 9, which extend parallel to one another in vertical planes and each serve to support a roller chain 10, 11.

Der Träger 6 ist in dem Rahmen 7 mittels eines Antriebs 17 zwecks Darstellung einer Vorschubbewegung in Richtung der Pfeile 5 verschiebbar. Der Antrieb 17 kann ein hydraulischer Antrieb sein.The carrier 6 can be displaced in the frame 7 by means of a drive 17 in order to display a feed movement in the direction of the arrows 5. The drive 17 can be a hydraulic drive.

Jede Rollenkette 10, 11 steht mit einem Kettenrad 12 im Eingriff, welches mit einem, auf einen Werkzeugschlitten 13 angeordneten Antrieb in Wirkverbindung steht, wobei der Werkzeugschlitten 13 um eine ideelle horizontale Achse 14 gegenüber dem Träger 6 schwenkbar gelagert ist. Das System der Führungen 8, 9 bildet somit Kreisbahnen um einen Drehpunkt, der durch die ideelle Achse 14 auf dem Träger 6 dargestellt ist.Each roller chain 10, 11 is in engagement with a chain wheel 12, which is in operative connection with a drive arranged on a tool slide 13, the tool slide 13 being pivotally mounted relative to the carrier 6 about an ideal horizontal axis 14. The system of guides 8, 9 thus forms circular paths around a pivot point, which is represented by the ideal axis 14 on the carrier 6.

Zur Sicherung der Arbeitsposition des Werkzeugschlittens 13 unter Arbeitsbelastung während der Bearbeitung der Schienen 2, 3, insbesondere des jeweiligen Schienenkopfes ist eine Bremsvorrichtung 18 vorgesehen, die automatisch während eines Verstellens entlang der genannten Kreisbahn gelöst wird. Die Bremsvorrichtung 18 ist beispielsweise als hydraulische Bremse ausgebildet, wobei jedoch andere Techniken nicht ausgeschlossen werden.To secure the working position of the tool carriage 13 under workload during the machining of the rails 2, 3, in particular the respective rail head, a braking device 18 is provided, which is automatically released during adjustment along the circular path mentioned. The braking device 18 is designed, for example, as a hydraulic brake, although other technologies are not excluded.

An dem, der zu bearbeitenden Schiene 3 zugekehrten Ende des Werkzeugschlittens 13 sind zwei zylindrische Schleifmittelträger 15 um eine Achse drehend antreibbar, die sich in Richtung auf den zu bearbeitenden Schienenkopf hin erstreckt. Die Zustellbewegung der Schleifmittelträger 15 erfolgt idealerweise in Richtung eines virtuellen Poles. Zur Darstellung der Zustellbewegung in Richtung auf den Schienenkopf hin ist der Werkzeugschlitten 13 mit einer Trägerstruktur 20 versehen, über welche der Vorschub der Schleifmittelträger 15 in dieser Richtung erfolgt. Der Werkzeugschlitten 13 umfasst den Drehantrieb der Schleifmittelträger 15 sowie einen Antrieb zwecks Darstellung einer Vorschubbewegung in Richtung der genannten Achse, somit der Pfeile 16.At the end of the tool slide 13 facing the rail 3 to be machined, two cylindrical abrasive carriers 15 can be driven to rotate about an axis which extends in the direction of the rail head to be machined. The feed movement of the abrasive carriers 15 ideally takes place in the direction of a virtual pole. To represent the feed movement in the direction of the rail head, the tool carriage 13 is provided with a support structure 20, via which the abrasive carrier 15 is advanced in this direction. The tool carriage 13 includes the rotary drive of the abrasive carrier 15 as well as a drive for the purpose of displaying a feed movement in the direction of the axis mentioned, thus the arrows 16.

Somit sind für die Bearbeitung des Schienenkopfes drei Zustellbewegungen des Schleifmittelträgers 15 eingerichtet, nämlich eine rotatorische um die Achse 14, eine erste translatorische in Richtung der Pfeile 16 auf den Schienenkopf hin und eine zweite translatorische in Richtung der Pfeile 5 in einer Horizontalebene.Thus, three feed movements of the abrasive carrier 15 are set up for processing the rail head, namely a rotational one about the axis 14, a first translational one in the direction of the arrows 16 towards the rail head and a second translational one in the direction of the arrows 5 in a horizontal plane.

Für die Koordinierung der Zustellbewegungen des Schleifmittelträgers 15 ist eine Steuerung vorgesehen, so dass ein teil- oder auch ein vollautomatischer Betrieb möglich ist.A control is provided for coordinating the feed movements of the abrasive carrier 15, so that partially or fully automatic operation is possible.

Schließlich ist mit 19 ein stabförmiger Träger für einen Leucht- oder Signalkörper bezeichnet.Finally, 19 denotes a rod-shaped support for a luminous or signaling body.
