In der US 4 896 460 B wird ein Schleifaggregat zum Abschleifen von Schienenkopfoberflächen eines Gleises mittels eines endlosen Schleifbandes geoffenbart. Dieses ist um angetriebene Umlenkrollen geführt bzw. gespannt und wird über eine Anpreßrolle an das Schienenkopfprofil angedrückt, wobei die Rollen um in Maschinenquerrichtung verlaufende Achsen rotieren.

This is guided or tensioned around driven deflection rollers and is pressed against the rail head profile via a pressure roller, whereby the rollers rotate around axes running in the cross-machine direction. The the supporting frame or the aggregate frame that supports the aggregate is with a Height adjustment device for feeding the sanding belt connected.

Aus der DE 38 40 006 C ist eine Schienenschleifvorrichtung bekannt, bei der ein endloses Schleifband quer zur Schienenlängsrichtung über die Laufflächen der Schienen geführt ist. Das Schleifband ist über Umlenkrollen gespannt, die an beiden Seiten des Schienenkopfes unter die Schienenoberkante absenkbar sind, wodurch das Band im Arbeitseinsatz den Schienenkopf teilweise umschlingt.From DE 38 40 006 C a rail grinding device is known from which is an endless sanding belt across the running surfaces across the length of the rail the rails are guided. The sanding belt is stretched over pulleys, on both sides of the rail head under the top edge of the rail can be lowered, which means that the strap can be used to work the rail head partially wraps around.
Die Aufgabe der vorliegenden Erfindung besteht in der Schaffung einer Schienenschleifmaschine der gattungsgemäßen Art mit erhöhter Schleifleistung. The object of the present invention is to provide a Rail grinding machine of the generic type with increased grinding performance.
Diese Aufgabe wird mit der im Anspruch 1 beschriebenen Maschine gelöst.This object is achieved with the machine described in
Ein derart ausgebildetes Schleifaggregat bietet eine erhebliche Steigerung
der Arbeitsleistung beim Abschleifen von Unregelmäßigkeiten an Schienenkopfoberflächen
gegenüber herkömmlichen Bandschleifaggregaten, bei denen
die Arbeitsbewegung der Schleifwerkzeuge relativ zur Schiene lediglich
von der Maschinenvorfahrt herrührt. Das erfindungsgemäße Schleifaggregat
ermöglicht ein qualitativ hochwertiges Schleifen schon bei einer einzigen Arbeitsdurchfahrt
der Maschine, während der jede Stelle der Schienenkopfoberfläche
durch das Schleifband aufgrund seiner Hin- und Herbewegung mehrmals
behandelt wird. Auf vorteilhafte Weise kann dabei die Arbeitsleistung
der Schleifmaschine problemlos den Erfordernissen im zu bearbeitenden
Gleis angepaßt werden, indem beispielsweise bei einer sehr unregelmäßigen
Schienenlauffläche durch bloßes Verlangsamen der Vorfahrtsgeschwindigkeit
der Maschine die Schleifleistung gezielt gesteigert werden kann und
umgekehrt. Im Gegensatz zu Schleifaggregaten mit endlosen umlaufenden
Schleifbändern kommt es bei der vorliegenden Erfindung zu wesentlich geringerer
Funkenentwicklung und daraus folgender Brandgefahr. Der Vorteil
gegenüber der Verwendung von Rutschersteinen o. dgl. liegt wiederum darin
begründet, daß diese leicht verschmutzen und auch sehr rasch durch die
vorstehenden Abquetschungen am Schienenkopf deformiert werden, wodurch
sie relativ schnell unbrauchbar werden und ausgetauscht werden müssen.
Das erfindungsgemäße Schleifband wird nach Abnutzung der Kontaktfläche
einfach weiter gespult und eignet sich daher in besonders wirtschaftlicher
Weise speziell zur Behandlung von Problembereichen der Schienenkopfoberflächen.
Im Zusammenhang damit ist mit der in Anspruch 2 dargelegten
Ausbildung die Abtragtiefe des Schleifbandes nach Belieben problemlos
und einfach regulierbar. A grinding unit designed in this way offers a considerable increase
the work performed when grinding irregularities on the rail head surfaces
compared to conventional belt sanding units where
the working movement of the grinding tools relative to the rail only
comes from the right of way. The grinding unit according to the invention
enables high-quality grinding in just one pass
of the machine, during which every point of the rail head surface
through the sanding belt several times due to its back and forth movement
is treated. The work performance can be advantageous
the grinding machine easily meets the requirements in the process
Track can be adjusted by, for example, a very irregular
Rail tread by simply slowing down the right of way
the grinding performance of the machine can be increased and
vice versa. In contrast to grinding units with endless revolving
Abrasive belts are much less in the present invention
Spark development and consequent fire risk. The advantage
compared to the use of slide stones or the like
justifies that these easily get dirty and also very quickly due to the
protruding pinches on the rail head are deformed, whereby
they become unusable relatively quickly and need to be replaced.
The abrasive belt according to the invention becomes worn after the contact surface
simply rewound and is therefore particularly economical
Specially for the treatment of problem areas of the rail head surfaces.
In connection with that is set out in
Die Weiterbildung gemäß dem Anspruch 3 gewährleistet auf konstruktiv
einfache Weise die oszillierende Beweglichkeit des Schleifaggregates
in bezug auf den Führungsrahmen, während die Ausbildung nach Anspruch
4 eine besonders platzsparende Anordnung der Spulen ermöglicht,
wodurch die in Maschinenlängsrichtung verlaufende Dimension des Aggregates
vorteilhaft gering gehalten werden kann.The training according to
Die in den Ansprüchen 5 bis 8 beschriebenen Varianten sichern eine exakte Positionierung des Schleifbandes relativ zum Andrückorgan und weiters eine genaue Anpassung der Kontaktfläche an das gewünschte Querschnittsprofil der Schiene zur Erzielung eines optimalen Arbeitsergebnisses bei den verschiedensten in der Praxis auftretenden Unregelmäßigkeiten am Schienenkopf.The variants described in claims 5 to 8 ensure an exact Positioning of the grinding belt relative to the pressure element and also one exact adaptation of the contact surface to the desired cross-sectional profile the rail to achieve an optimal work result with the most diverse irregularities in the rail head that occur in practice.
Die Weiterbildung nach Anspruch 9 bietet den Vorteil, zwei Schleifaggregate
pro Schiene mit einander gegenläufigen oszillierenden Bewegungen beaufschlagen
zu können, um so zusätzlich zum Vorteil einer erhöhten Schleifleistung
ein störendes Vibrieren bzw. Schwingen des Führungsrahmens zu
eliminieren oder zumindest auf ein Mindestmaß zu beschränken.The development according to
Schließlich ist es mit der Weiterbildung nach Anspruch 10 möglich, das
Schleifband insbesondere bei starken Verschleißbeanspruchungen mit langsamer
Geschwindigkeit ohne Unterbrechung der Arbeitsvorfahrt über die zu
schleifende Schiene zu bewegen.Finally, it is possible with the training according to
Die Erfindung wird im folgenden unter Bezugnahme auf ein in der Zeichnung dargestelltes Ausführungsbeispiel näher beschrieben.The invention will now be described with reference to an in the drawing illustrated embodiment described in more detail.
Es zeigen:
Eine in Fig. 1 ersichtliche Schienenschleifmaschine 1 weist einen Maschinenrahmen
2 auf, der über Schienenfahrwerke 3 auf einem Gleis 4 abgestützt
und in einer Arbeitsrichtung 5 verfahrbar ist. Die Maschine 1 ist mit endseitig
angeordneten Fahrkabinen 6 und einer Energiezentrale 7 zur Versorgung
eines Fahrantriebes 8 sowie aller weiteren auf der Maschine befindlichen
Antriebe versehen.A
Zum Zwecke des Abschleifens von Unregelmäßigkeiten an Schienenkopfoberflächen
9 von Schienen 10 des Gleises 4 ist die Maschine 1 mit in Schienenlängsrichtung
hintereinander oberhalb jeder der beiden Schienen 10 angeordneten
Schleifeinheiten 11,12 ausgestattet. Die - auf der in Arbeitsrichtung
5 hinteren Maschinenhälfte befindlichen - Schleifeinheiten 11 sind
dabei in herkömmlicher Art und Weise mit sogenannten Rutschersteinen 13
ausgebildet und an sich bekannt und werden daher an dieser Stelle nicht näher
beschrieben. Der konstruktive Aufbau der beiden einander am vorderen
Ende der Maschine 1 in Maschinenquerrichtung gegenüberliegenden Schleifeinheiten
12 wird aus der Fig. 2 deutlich.For the purpose of sanding irregularities on the
Die Schleifeinheit 12 weist einen Führungsrahmen 14 auf, der sich in Gleislängsrichtung
erstreckt und an seinen beiden Enden über Spurkranzrollen
15 auf der Schiene 10 abrollbar ist. Die Spurkranzrollen 15 sind dabei relativ
zum Führungsrahmen 14 anhand von Antrieben 16 der Höhe nach verstellbar
ausgebildet, während der Führungsrahmen 14 selbst über jeweils endseitig
daran angelenkte Höhenverstellantriebe 17 mit dem Maschinenrahmen 2
verbunden und zu diesem höhenverstellbar ist. Die Höhenverstellantriebe 17
sind als doppeltwirkende Hydraulikzylinder ausgebildet und dienen sowohl
zum Abheben der Schleifeinheit 12 vom Gleis 4 als auch zum Aufbringen
einer vertikalen Auflast beim Arbeitseinsatz. The
Der Führungsrahmen 14 ist mit zwei Schleifaggregaten 18 ausgestattet, die
in Maschinenlängsrichtung hintereinander oberhalb der Schiene 10 angeordnet
und jeweils mit einem Werkzeugrahmen 19 versehen sind. Dieser ist auf
mit dem Führungsrahmen 14 verbundenen, in Maschinenlängsrichtung und
horizontal bzw. parallel zur Schienenoberkante verlaufenden Führungssäulen
20 relativ zum Führungsrahmen 14 verschiebbar gelagert. Zwischen den
beiden Schleifaggregaten 18 befindet sich eine mit dem Führungsrahmen 14
verbundene Antriebsvorrichtung 21, die als Exzenterantrieb 22 mit zwei Antriebswellen
23 ausgebildet ist. Diese sind über jeweils eine Pleuelstange 24
mit dem Werkzeugrahmen 19 gelenkig verbunden und beaufschlagen die
Schleifaggregate 18 mit einer in Maschinenlängsrichtung hin- und hergehenden,
gegenläufigen Bewegung (siehe kleine Pfeile in Fig. 2).The
Jedes Schleifaggregat 18 ist in weiterer Folge mit einem Schleifband 25 ausgestattet,
dessen Enden auf einer Vorratsspule 26 bzw. einer Sammelspule
27 aufgerollt sind und das über ein am unteren Ende des Werkzeugrahmens
19 befindliches Andrückorgan 28 verläuft, mittels dessen das Schleifband 25
an die Schienenkopfoberfläche 9 angepreßt werden kann. Die Vorrats- und
Sammelspule 26,27 sind in vertikaler Richtung übereinander oberhalb des
Andrückorganes 28 auf dem Werkzeugrahmen 19 gelagert und jeweils um
eine horizontale, in Maschinenquerrichtung verlaufende Achse 29 rotierbar
ausgebildet, wobei jede Vorratsspule 26 zum Zweck einer Vorspannung des
Schleifbandes 25 mittels einer eigenen Bremseinrichtung 30 ausgestattet ist.
Jede Sammelspule 27 ist mit einem stufenlos steuerbaren Motor 39 verbunden,
um damit das Schleifband wahlweise im Arbeitseinsatz mit langsamer
Geschwindigkeit auf die Sammelspule 27 aufzuwickeln. Weiters sind am
Werkzeugrahmen 19 Umlenkrollen 31 für die Führung des Schleifbandes 25
zwischen den beiden Spulen 26,27 vorgesehen. Die beiden in Maschinenquerrichtung
jeweils einander gegenüberliegenden Schleifeinheiten 11,12
werden durch nicht näher dargestellte, an sich bekannte Spreizantriebe -
zur
Ausschaltung des Spurspieles bzw. zur Anpressung des Schleifbandes 25
an die innere Kopfrundung 37 der Schiene 10 - gegen die jeweilige Schieneninnenseite
gepreßt (s. Pfeil 40 in Fig. 3). Each
Wie insbesondere auch in Fig. 3 zu erkennen, ist das Andrückorgan 28 als
länglich ausgebildeter Anpreßschuh 32 geformt, der an seiner Unterseite
eine Kontaktfläche 33 mit dem Schleifband 25 aufweist und in Maschinenlängsrichtung
bzw. parallel zur Schiene 10 verläuft. Ein Querschnittsprofil 38
der Kontaktfläche 33 entspricht bezüglich der Fahrfläche sowie der
Schienenkopf-Innenseite dem gewünschten Querschnittsprofil der Schienenkopfoberfläche
9. An den in Schienenquerrichtung einander gegenüberliegenden
Seiten des Anpreßschuhes 32 ist die Kontaktfläche 33 über die jeweilige
Kopfrundung 37 der Schiene 10 hinaus nach unten gezogen und erstreckt
sich bis etwa zum Beginn des vertikalen Bereiches der Schienenkopfflanken
34. Damit wird dem Schleifband 25 gerade im größere Deformationen
aufweisenden Kopfrundungsbereich eine gleichbleibende Abstützung
gegeben. Der Anpreßschuh 32 ist im Bereich einer äußeren Kopfrundung 41
- und damit auch das Schleifband 25 - von der Schiene 10 distanziert. Bezüglich
der Maschinenlängsrichtung unmittelbar vor und hinter dem Anpreßschuh
32 ist jeweils eine Doppelspurkranzrolle 35 am Werkzeugrahmen 19
montiert, die um eine in Maschinenquerrichtung verlaufende Achse 36 rotierbar
und die derart angeordnet ist, daß sie - in Arbeitsstellung des Schleifaggregates
18 - von der Schienenkopfoberfläche 9 geringfügig distanziert ist
und so das Schleifband 25 präzise in seiner seitlichen Position relativ zum
Anpreßschuh 32 fixiert bzw. führt.As can also be seen in particular in FIG. 3, the
Im Einsatz zum Abschleifen von Unregelmäßigkeiten der Schienenkopfoberfläche
wird die Maschine 1 kontinuierlich in Arbeitsrichtung 5 verfahren, während
die Schleifaggregate 18 anhand des Exzenterantriebes 22 in eine dieser
Maschinenvorfahrt überlagerte, oszillierende Arbeitsbewegung versetzt
und die Schleifbänder 25 mittels der Höhenverstellantriebe 17 an die Schienenkopfoberfläche
9 gepreßt werden. Die gewünschte Abtragtiefe beim Abschleifen
wird anhand der Antriebe 16 reguliert. Bei Verschmutzung bzw.
nach Abnutzung der Schleifbänder 25 an ihrer mit der Schiene 10 in Eingriff
stehenden Kontaktfläche wird die Schleifeinheit 12 von der Schiene abgehoben
und jedes Schleifband 25 - nach Lösung der Bremseinrichtung 30 - um
die entsprechende verbrauchte Länge von der Vorratsrolle 26 auf die Sammelrolle
27 weitergespult. Zweckmäßigerweise kann die Schleifeinheit 12
mit den Schleifaggregaten 18 insbesondere zur Bearbeitung von jenen Bereichen
der Schienenkopfoberflächen eingesetzt werden, die z. B. aufgrund
von Überwalzungsgraten o. dgl. problematisch für die Anwendung der an
den Schleifeinheiten 11 vorgesehenen Rutschersteine 13 sind. Deshalb ist
