Abstract

For rerailing a rail grinding machine provided with at least one grinding device, there are provided on a first basic frame and a second basic frame corresponding rollers for running along the rails of a line of rails. The second basic frame (45) comprises essentially a first frame part (40) as well as a second frame part (46) which parts are in work connection with one another via a guide pipe (44). The second frame part (46) is adjustable in relation to the first frame part (40) by means of a spindle device (60) and readjustable by correspondingly arranged energy accumulators (49, 49'). As a result, track changes of the line of rails which arise, for example in bends, are correspondingly compensated and consequently tilting of the rail grinding machine between the rails is prevented. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Schienen-Schleifmaschine gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a rail grinding machine according to the preamble of claim 1.

Eine entsprechende Schienen-Schleifmaschine ist bekannt aus der EP-A-0 110 246. Die dort beschriebene Maschine weist einen verschwenkbar mit einem Fahrgestellrahmen verbundenen Maschinenrahmen mit einem als Schleifband ausgebildeten Schleifwerkzeug auf. Der Fahrgestellrahmen wird mittels Feststellschrauben der Schienenspurweite angepasst.A corresponding rail grinding machine is known from EP-A-0 110 246. The machine described there has a machine frame pivotably connected to a chassis frame with a grinding tool designed as a grinding belt. The chassis frame is adjusted to the track gauge by means of locking screws.

In der nicht vorveröffentlichten EP-A-0 444 242 ist an einem Grundrahmen eine erste und eine zweite Schleifvorrichtung angeordnet, wobei mittels der ersten Schleifvorrichtung ein Bearbeiten der Schienenoberfläche in Längsrichtung und mittels der zweiten Schleifvorrichtung eine Bearbeitung der Schienenoberfläche quer zur Längsrichtung erfolgt. Beide Schleifvorrichtungen sind an dem Grundrahmen angeordnet, welcher mittels entsprechend daran gelagerter Laufrollen auf den parallel laufenden Schienensträngen abgestützt ist.In the unpublished EP-A-0 444 242, a first and a second grinding device are arranged on a base frame, with the first grinding device processing the rail surface in the longitudinal direction and the second grinding device processing the rail surface transversely to the longitudinal direction. Both grinding devices are arranged on the base frame, which is supported on the parallel running rail tracks by means of correspondingly mounted rollers.

Grundsätzlich besteht bei allen bekannten Schienen-Schleifmaschinen das Problem des Verkantens innerhalb des Geleises, da die Schienenstränge nicht immer in dem gleichen Abstand zueinander laufen.Basically, with all known rail grinding machines there is the problem of canting within the track, since the rail strands do not always run at the same distance from one another.

Gemäss der CH 670 667 erfolgt eine Änderung des Abstandes der parallel laufenden Laufrollen mittels eines hydraulisch betriebenen Zylinders, welcher zwischen zwei Teilen der Vorrichtung angeordnet ist. Durch diesen Zylinder kann jedoch keine selbsttätige Feineinstellung erfolgen, wie dies beispielsweise in Kurven notwendig ist. Gerade in Kurven wäre es jedoch wünschenswert, wenn die Spur sich selbsttätig ändern könnte.According to CH 670 667, the distance between the parallel running rollers is changed by means of a hydraulically operated cylinder, which is between two parts of the device is arranged. However, this cylinder cannot be used for automatic fine adjustment, as is necessary, for example, in curves. Especially in curves, however, it would be desirable if the track could change automatically.

Der Erfindung liegt die Aufgabe zugrunde, eine entsprechende Vorrichtung für eine Schienen-Schleifmaschine der eingangs genannten Art zu schaffen, mittels welcher ein Einspuren sowie eine selbsttätige Anpassung der Laufrollen an etwaige Spuränderungen gewährleistet wird und somit ein Verkanten der Schienen-Schleifmaschine im Geleise verhindert wird.The invention has for its object to provide a corresponding device for a rail grinding machine of the type mentioned, by means of which an engagement and an automatic adaptation of the rollers to any track changes is guaranteed and thus tilting of the rail grinding machine on the track is prevented.

Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass der zweite Grundrahmen ein erstes Rahmenteil mit einem Tragteil zur Lagerung einer Gewindespindel sowie ein zweites Rahmenteil mit einem Tragteil zur Lagerung der Gewindespindel umfasst, mittels welcher das zweite Rahmenteil quer zur Schienenlängsrichtung relativ zu dem ersten Rahmenteil gegen den Druck mindestens eines Kraftspeichers derart voreinstellbar ist, dass die beiden am zweiten Grundrahmen angeordneten Laufrollen in Betrieb durch die Rückstellkraft des Kraftspeichers federelastisch anliegend an der Zweiten Laufschiene angeordnet sind.The object is achieved according to the invention in that the second base frame comprises a first frame part with a support part for mounting a threaded spindle and a second frame part with a support part for mounting the threaded spindle, by means of which the second frame part transversely to the longitudinal direction of the rail relative to the first frame part against the pressure at least one energy accumulator can be preset such that the two running rollers arranged on the second base frame are in operation arranged in a resilient manner against the second running rail due to the restoring force of the energy accumulator.

Zur Voreinstellung des Abstandes der am Rahmenteil 46 des zweiten Grundrahmens 45 gelagerten Laufrollen 31' und 32', relativ zu den am ersten Grundrahmen 30 gelagerten Laufrollen 31 und 32, wird das Handrad 61 entsprechend gedreht. Hierbei wird die mit dem Handrad 61 wirkverbundene Spindelmutter 65 auf der feststehenden Gewindespindel 62 und gleichzeitig das auf dem Führungsrohr 44 gelagerte zweite Rahmenteil 46 mit dem Traggestell 50, wie in Fig.4 mit Pfeilrichtung Y bezeichnet, entsprechend bewegt. Die Voreinstellung erfolgt derart, dass die beiden Laufrollen 31'und 32' mit ihren nicht näher bezeichneten Führungen in geringem Abstand zum Schienenkörper sind. Beim Fahren der gesamten Schienen-Schleifmaschine 100 wird, nach dem Lösen der Spindelvorrichtung, das Rahmenteil 46 mit den beiden Laufrollen 31',32' durch die Rückstellkraft der Gasdruckfedern 49,49' in Pfeilrichtung Y', wie in Fig.4 dargestellt, gegen die Schiene 2' gedrückt.
   Mit der federelastischen Rückstellkraft der Gasdruckfedern 49,49' wird erreicht, dass die beiden Laufrollen 31' und 32' mit dem Rahmenteil 46 bei etwaigen Spuränderungen oder aber in Kurven sich an den jeweiligen Abstand der beiden Schienen 2,2' automatisch anpasst.
   Die vorstehend beschriebene Eingleisvorrichtung 75 kann auf einfache Art und Weise an bereits vorhandene Schienen-Schleifmaschinen angebracht werden. Hierzu ist lediglich der feststehende Grundrahmen 30 mit dem Grundrahmen 45 entsprechend zu koppeln bzw. verschiebbar auf dem Führungsrohr 44 zu lagern.To preset the distance between the rollers 31 'and 32' mounted on the frame part 46 of the second base frame 45, relative to the rollers 31 and 32 mounted on the first base frame 30, the handwheel 61 is rotated accordingly. Here, the spindle nut 65, which is operatively connected to the handwheel 61, is moved accordingly on the fixed threaded spindle 62 and, at the same time, the second frame part 46, which is mounted on the guide tube 44, with the support frame 50, as indicated in FIG. The presetting is carried out in such a way that the two rollers 31 'and 32' with their guides, which are not described in more detail, are at a short distance from the rail body. When driving the entire rail grinding machine 100, after loosening the spindle device, the frame part 46 with the two rollers 31 ', 32' is counteracted by the restoring force of the gas pressure springs 49,49 'in the direction of the arrow Y', as shown in FIG the rail 2 'pressed.
With the resilient restoring force of the gas pressure springs 49, 49 'it is achieved that the two rollers 31' and 32 'with the frame part 46 in the event of any lane changes or in curves depend on the respective distance between the two Automatically adjusts rails 2,2 '.
The single-track device 75 described above can be attached to existing rail grinding machines in a simple manner. For this purpose, only the fixed base frame 30 is to be correspondingly coupled to the base frame 45 or slidably mounted on the guide tube 44.

Der Gegendruck gegen die Relativbewegung der beiden Rahmenteile 40,46 wird bevorzugt mit einer Gasdruckfeder 49,49' erreicht. Hierdurch werden auftretende Spuränderungen der Geleise 1, beispielsweise in Kurven entsprechend ausgeglichen und dadurch ein Verkanten der Schienen-Schleifmaschine 100 zwischen den Schienen 2,2' verhindert.The counter pressure against the relative movement of the two frame parts 40, 46 is preferably achieved with a gas pressure spring 49, 49 '. As a result, any changes in the track of the track 1, for example in curves, are correspondingly compensated, and thereby tilting of the rail grinding machine 100 between the rails 2, 2 ′ is prevented.
