Description

Die Erfindung bezieht sich auf eine Vorrichtung zur spanenden Bearbeitung eines Gleises.The invention relates to a device for machining a track.

In der Eisenbahnwartungstechnik ist es bekannt, kontinuierlich arbeitende Schleif-, Hobel- und Fräsmaschinen vorzusehen, welche die Schienenoberflächen und das Schienenprofil bearbeiten und gegebenenfalls nach Verschleiß wiederherstellen können. Dabei handelt es sich um massive Oberbauinstandhaltungsmaschinen, die den Bearbeitungsprozesses während der Fahrt erledigen. Mit solchen Geräten wird die Oberfläche bzw. wird das Schienenprofil auf einer langen Fahrtstrecke wiederhergestellt. Neben derartigen Profilierungsaufgaben gibt es allerdings auch räumlich eng begrenzte Qualitätsmängel, die als Einzelfehler von Schienen bzw. auch Weichenanlagen anzusehen sind. Gleis ist in diesem Zusammenhang in der Folge als mit Schiene und Weiche gleichwertig zu betrachten um Wiederholungen zu vermeiden. Einzelfehler können beispielsweise Ausbröckelungen, Eindrückungen, Rissnester, tiefere Risse in Schienen oder abgefahrene Herzstücke in Weichen sein. Bei Einzelfehlern solcher Art wird im Regelfall ein mindestens 6 Meter langes Schienenstück herausgeschnitten, eine neue Schiene eingesetzt und diese mit der alten Schiene verschweißt. Bei abgefahrenen Herzstücken in Weichen werden diese auftragsgeschweißt, wenn es sich um schweißbare Herzstücke handelt, und anschließend abgeschliffen bzw. werden neue Herzstücke eingesetzt. Dazu können insbesondere mobile Schweißgeräte, aber auch Schweißroboter eingesetzt werden, welche die nötigen Auftragsschweißungen durchführen. Nachteilig ist insbesondere, dass entweder erhebliche Gleisabschnitte zur Reparatur ausgetauscht werden müssen oder aber auch langwierige manuelle Ausbesserungsarbeiten zur Gleitreparatur vorgenommen werden müssen. Ein automatisiertes Ausbessern von kleineren Fehlstellen an Gleisen ist mit den bekannten Vorrichtungen kaum möglichst bzw. sind diese bekannten Vorrichtungen zu unhandlich und schwerfällig.In railway maintenance technology it is known to provide continuous grinding, planing and milling machines which can machine the rail surfaces and the rail profile and optionally restore it to wear. These are massive superstructure maintenance machines that handle the machining process while driving. With such devices, the surface or the rail profile is restored on a long drive. In addition to such profiling tasks, however, there are also spatially narrow quality defects, which are to be regarded as a single fault of rails or turnouts. In this context, track is to be regarded as equivalent to track and switch in order to avoid repetition. Single faults can be, for example, chipping, indentations, cracking cracks, deeper cracks in rails or worn-out frogs in turnouts. In the case of individual defects of this kind, a rail piece at least 6 meters long is usually cut out, a new rail is inserted and welded to the old rail. In the case of worn frogs in turnouts, these are contract welded if they are weldable frogs and then ground down or new frogs are inserted. For this purpose, in particular mobile welding equipment, but also welding robots can be used, which perform the necessary build-up welding. A particular disadvantage is that either significant track sections need to be replaced for repair or tedious manual repair work for sliding repair must be made. One automated mending of minor defects on tracks is hardly possible with the known devices or these known devices are too unwieldy and cumbersome.

Ausgehend von einem Stand der Technik der vorgeschilderten Art liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zur spanenden Bearbeitung eines Gleises zu schaffen, die eine möglichst rasche Reparatur von Fehlstellen in Gleisen erlaubt. Insbesondere soll eine mobile Vorrichtung geschaffen werden, welche gegebenenfalls von wenigen Personen gehandhabt bzw. transportiert werden kann.Based on a prior art of the pre-described type, the invention has for its object to provide a device for machining a track, which allows the fastest possible repair of defects in tracks. In particular, a mobile device is to be created, which may possibly be handled or transported by a few people.

Die Erfindung löst diese Aufgabe durch ein Werkzeugbett, dem eine wenigstens ein Bearbeitungswerkzeug aufnehmende Freiformfräsanlage und wenigstens zwei einen Bearbeitungsraum umgreifende Klemmarme zugeordnet sind, wobei die Klemmarme Klemmbacken tragen, die mit einer Spannvorrichtung zum Festlegen des Werkzeugbettes an einem Gleis vorgesehen sind.The invention solves this problem by a tool bed, which are associated with at least one machining tool receiving Freiformfräsanlage and at least two processing space encompassing clamping arms, the clamping arms carry jaws, which are provided with a clamping device for fixing the tool bed on a track.

Mit der Erfindung wird eine mobile bzw. verhältnismäßig einfach zu transportierende Freiformfräsanlage geschaffen, die insbesondere zum Ausbessern kleinerer Fehlstellen an Gleisen besonders gut geeignet ist. Eine derartige Vorrichtung umfasst insbesondere ein Werkzeugbett, auf dem gegebenenfalls erforderliche Aggregate, wie Stromgenerator, Hydraulikaggregate, Steueranlagen und dgl. aufgebaut sein können. Auf der Werkzeugbettunterseite ist die das wenigstens eine Bearbeitungswerkzeug aufnehmende Freiformfräsanlage aufgebaut, die derart ausgebildet ist, dass sie von der Werkzeugbettunterseite gegen eine zu reparierende Schiene anstellbar ist. Des Weiteren ragen vom Werkzeugbett wenigstens zwei Klemmarme nach unten gegen das Gleitprofil, welche Klemmarme den Bearbeitungsraum umgreifen. Zudem tragen die Klemmarme Klemmbacken, die mit einer Spannvorrichtung zum Festlegen des Werkzeugbettes an einem Gleis vorgesehen sind. Die Klemmarme und/oder die Klemmbacken sind dabei mittels der Spannvorrichtung derart gegen das Schienenprofil verspannbar, dass das Werkzeugbett lagefest gehalten ist. Erfindungsgemäß soll über diese Klemmvorrichtung die Fräsanlage mit der Schiene derart fest verbunden sein, dass es zu einer automatischen Ausrichtung des Werkzeugbettes gegenüber dem Bezugssystemschiene kommt.With the invention, a mobile or relatively easy to transport freeform milling is created, which is particularly well suited for repairing small defects on tracks. Such a device comprises, in particular, a tool bed on which optionally required aggregates, such as power generator, hydraulic units, control systems and the like can be constructed. On the bottom of the tool bed, the free-form milling system accommodating the at least one machining tool is constructed, which is designed such that it can be adjusted from the base of the tool bed against a rail to be repaired. Furthermore protrude from the tool bed at least two clamping arms down against the slide, which clamping arms embrace the processing space. In addition, the clamping arms carry clamping jaws, which are provided with a clamping device for fixing the tool bed to a track. The clamping arms and / or the jaws are clamped by means of the clamping device against the rail profile such that the tool bed is held firmly in position. According to the invention on this clamping device, the milling machine with the Rail are firmly connected so that there is an automatic alignment of the tool bed relative to the reference system rail.

Zur automatischen Vermessung des zu bearbeitenden Schienenstranges kann dem Werkzeugbett eine Gleisvermessungseinrichtung, insbesondere ein optischer Messsensor, vorzugsweise ein Laserscanner und/oder ein PMD-Sensor, und/oder ein Tastsensor, zugeordnet sein. In einem besonders einfachen Fall wird die Freiformfräsanlage zur Vermessung des Gleises mit einem ein Gleisprofil abtastenden Messkopf ausgestattet. Somit kann das Bezugssystem Schiene mit dem Messkopf abgetastet werden. Abgetastet werden der Schienenverlauf und die auszubessernde Fehlstelle. Aus den ausgewerteten Daten wird in weiterer Folge der abzufräsende Bereich ermittelt. Die Fehlstelle wird mit dem Fräser ausgefräst und der entfernte, defekte Bereich in weiterer Folge in einer oder in mehreren Lagen aufgeschweißt. Dieses Aufschweißen kann gegebenenfalls manuell erfolgen.For automatic measurement of the rail track to be processed, the track bed can be assigned a track measuring device, in particular an optical measuring sensor, preferably a laser scanner and / or a PMD sensor, and / or a touch sensor. In a particularly simple case, the freeform milling machine for measuring the track is equipped with a measuring head which scans a track profile. Thus, the reference frame rail can be scanned with the measuring head. Scanned are the track and the patch to be repaired. The area to be scanned is subsequently determined from the evaluated data. The defect is milled out with the cutter and the removed, defective area subsequently welded in one or more layers. This welding can be done manually if necessary.

Besonders vorteilhaft ist es, wenn der Freiformfräsanlage ein Schweißkopf und eine Schweißdrahtführung zugeordnet sind. So kann mit einem und demselben Roboterarm bzw. Schlitten der Fräsvorgang und auch der Schweißvorgang durchgeführt werden. Im Bedarfsfall könnte allerdings auch ein zweiter Roboterarm bzw. Schlitten für den Aufschweißvorgang vorgesehen sein. Besonders einfache und robuste Konstruktionsverhältnisse ergeben sich dabei, wenn dem Werkzeugbett ein das wenigstens eine Bearbeitungswerkzeug aufnehmender Kreuzschlitten zugeordnet ist. Dieser Kreuzschlitten trägt dann beispielsweise das Fräswerkzeug und gleichermaßen den Schweißkopf. Alternativ oder Zusätzlich könnte aber auch ein Roboterarm das Werkzeug, den Schweißkopf und/oder den Messsensor führen.It when the Freiformfräsanlage a welding head and a welding wire guide are assigned is particularly advantageous. Thus, with one and the same robot arm or carriage, the milling process and also the welding process can be carried out. If necessary, however, a second robot arm or carriage could also be provided for the welding process. Particularly simple and robust construction conditions arise when the tool bed is associated with the at least one machining tool receiving cross slide. This cross slide then carries, for example, the milling tool and equally the welding head. Alternatively or additionally, however, a robot arm could also guide the tool, the welding head and / or the measuring sensor.

In weiterer Folge fräst der Freiformfräser wieder das Profil der Schiene. Der Vorteil eines Freiformfräsers gegenüber einem Formfräser ist insbesondere, dass beliebige Schienen oder Herzstückprofile, Zungenprofile und dgl. gefräst werden können, ohne den Fräser tauschen zu müssen. Zur automatisierten Vermessung, Auftragsschweißung und Korrekturfräsung eines Gleisprofils ist der Vorrichtung insbesondere eine Steuerung zugeordnet. Zudem kann der Freiformfräsanlage ein Werkzeugwechsler zugeordnet sein, der einen unkomplizierten Werkzeugtausch ermöglicht. Da die Verbindung mit der Schiene derart fest sein muss, dass sich das Werkzeugbett während einer Bearbeitung nicht verschieben oder verlagern kann und dass auch keine Schnittkräfte zu einer Verschiebung bzw. Verlagerung führen, wird vorgeschlagen, dass die Klemmbacken hydraulisch gegen ein Gleis anstellbar sind, wobei die keilförmig ausgebildeten Klemmbacken eine Schiene insbesondere zwischen Schienenkopfunterseite und Schienenfußoberseite klemmend greifen. Der Verbindungssteg zwischen Schienenfuß und Schienenkopf wird dabei vorzugsweise nicht geklemmt, um diese gewünschte Sicherheit zu erzielen. Eine Klemmung in einem Herzstückbereich einer Weiche kann in ähnlicher Weise durch Anspreizen an den links und rechts vom Herzstück befindlichen Schienen erfolgen.Subsequently, the freeform cutter mills the profile of the rail again. The advantage of a free-form milling cutter compared to a form milling cutter is, in particular, that any rails or frog profiles, tongue profiles and the like can be milled without having to replace the router. For automated measurement, build-up welding and Korrekturfräsung a track profile of the device is assigned in particular a controller. In addition, the Freiformfräsanlage can be assigned a tool changer, which allows a simple tool exchange. Since the connection to the rail must be so strong that the tool bed can not move or shift during processing and that also no cutting forces lead to a shift or displacement, it is proposed that the jaws are hydraulically engageable against a track, said the wedge-shaped clamping jaws gripping a rail, in particular between rail head underside and upper rail side clamping. The connecting web between rail foot and rail head is preferably not clamped in order to achieve this desired security. Clamping in a frog area of a turnout can similarly be done by tipping on the rails located to the left and right of the frog.

Des Weiteren betrifft die Erfindung einen Oberbauinstandhaltungsmaschine für Gleisanlagen mit einer erfindungsgemäßen Vorrichtung. Das gesamte erfindungsgemäße Aggregat soll mit einer derartigen Oberbauinstandhaltungsmaschine bis zur Arbeitsstelle verfahren werden können, wo das Aggregat abgesenkt und an die Schiene angeklemmt wird, bevor der Vermessungs- und Bearbeitungsprozess gestartet wird. Dieser Prozess soll weitgehend automatisch ablaufen.Furthermore, the invention relates to a track maintenance machine for track systems with a device according to the invention. The entire unit according to the invention should be able to be moved with such a superstructure maintenance machine to the workplace, where the unit is lowered and clamped to the rail before the surveying and machining process is started. This process should be largely automatic.

Die Klemmbacken 7 sind mit Hydraulikzylindern 8 gegen das Gleis 1 anstellbar, wobei die keilförmig ausgebildeten Klemmbacken 7 eine Schiene insbesondere zwischen Schienenkopfunterseite und Schienenfu ßoberseite klemmend greifen.An inventive device for machining a track 1, in particular a rail or switch, comprises a tool bed 2, which is associated with at least one machining tool 3, a milling cutter, receiving Freiformfräsanlage. In addition, the tool bed 2 four a processing chamber 5 comprehensive clamping arms 6, two each rail side, provided with the clamping arms 6 jaws 7 wear, which are provided with a chip device 8 (hydraulic cylinder) for fixing the tool bed 2 on a track 1.
