A grinding device is raised and lowered relative to the frame by means of a spindle drive.

Zusammenfassung der ErfindungSummary of the invention

Der Erfindung liegt die Aufgabe zugrunde, für eine Schleifmaschine der eingangs genannten Art eine Verbesserung gegenüber dem Stand der Technik anzugeben.The invention is based on the object of specifying an improvement over the prior art for a grinding machine of the type mentioned at the beginning.

Erfindungsgemäß wird diese Aufgabe gelöst durch eine Schleifmaschine gemäß Anspruch 1. Abhängige Ansprüche geben vorteilhafte Ausgestaltungen der Erfindung an.According to the invention, this object is achieved by a grinding machine according to claim 1. Dependent claims specify advantageous embodiments of the invention.

Die Erfindung sieht vor, dass die jeweilige Schienenführung eine Schnellwechselvorrichtung umfasst, in der eines von zumindest zwei gegeneinander austauschbaren Schienenführungssystemen befestigt ist. Dadurch kann die Schienenführung einfach an die örtlichen Gegebenheiten der Baustelle angepasst werden. Insbesondere ermöglichen die unterschiedlichen Führungen je nach Arbeitssituation eine ergonomische Bedienung sowie einen flexiblen Einsatz der Schleifmaschine.The invention provides that the respective rail guide comprises a quick-change device in which one of at least two mutually interchangeable rail guide systems is attached. This allows the rail guide to be easily adapted to the local conditions on the construction site. In particular, the different guides enable ergonomic operation and flexible use of the grinding machine, depending on the work situation.

In einer vorteilhaften Ausprägung der Erfindung ist vorgesehen, dass die jeweilige Schnellwechselvorrichtung eine Buchse mit einer Innenverzahnung umfasst und dass das jeweilige Schienenführungssystem einen Zapfen mit einer Außenverzahnung umfasst. Durch die formschlüssige Verbindung der Schnellwechselvorrichtung wird eine sichere Führung der Schleifmaschine gewährleistet. Der Zapfen mit Außenverzahnung wird in die Buchse mit Innenverzahnung geschoben und das jeweilige Schienenführungssystem schnell und einfach gewechselt.In an advantageous embodiment of the invention, it is provided that the respective quick-change device comprises a bushing with an internal toothing and that the respective rail guide system comprises a pin with an external toothing. The positive connection of the quick-change device ensures safe guidance of the grinding machine. The pin with external teeth is pushed into the socket with internal teeth and the respective rail guide system can be changed quickly and easily.

Eine weitere vorteilhafte Variante der Erfindung sieht vor, dass das Schleiforgan mit dem Antriebsmotor über ein Getriebe zur Kraftübertragung verbunden ist. Die Kraftübertragung auf das Schleiforgan erfolgt dabei in optimierter Weise, wobei der Antriebsmotor und das Schleiforgan auf unterschiedlichen Achsen angeordnet sein können.A further advantageous variant of the invention provides that the grinding element is connected to the drive motor via a transmission for power transmission. The power transmission to the grinding element takes place in an optimized manner, with the drive motor and the grinding element being able to be arranged on different axes.

Eine weitere Verbesserung der erfindungsgemäßen Vorrichtung sieht vor, dass ein Widerstand einer Höhenverstellung des Schleiforgans mittels eines Verstellelements einstellbar ist. Die Höhenverstellung ist somit im Arbeitseinsatz auf die jeweilige Anforderung anpassbar, insbesondere um einen Verschleiß des Schleiforgans zu kompensieren. Der Wiederstand der Höhenverstellung ist dabei in einfacher Art und Weise auf die individuellen Anforderungen einer Bedienperson einstellbar.A further improvement of the device according to the invention provides that a resistance to a height adjustment of the grinding member can be adjusted by means of an adjusting element. The height adjustment can thus be adapted to the respective requirement during work, in particular to compensate for wear on the grinding member. The resistance of the height adjustment can be adjusted in a simple manner to the individual requirements of an operator.

In einer vorteilhaften Ausprägung der Erfindung ist vorgesehen, dass ein erstes Schienenführungssystem lediglich eine innere Tellerscheibe und eine äußere Tellerscheibe zum Anlegen an einen Schienenkopf umfasst. Die zwei Tellerscheiben werden zur Bearbeitung des Schienenkopfes einfach im gewünschten Winkel auf diesen aufgesetzt. Dadurch ist ein schneller und unkomplizierter Arbeitsfortschritt gewährleistet.In an advantageous embodiment of the invention, it is provided that a first rail guide system comprises only an inner cup washer and an outer cup washer for placing on a rail head. The two cup washers are simply placed on the rail head at the desired angle to process it. This ensures quick and uncomplicated work progress.

Dabei ist es günstig, wenn eine Drehachse der äußeren Tellerscheibe gegenüber einer Drehachse der inneren Tellerscheibe um einen Winkel nach unten geneigt ist. Auf diese Weise wirkt beim Seitenschleifen von der Schiene auf die Schleifmaschine eine höhere Halte- bzw. Klemmkraft. Das Schleiforgan wird fester zum Schienenkopf hingezogen, wodurch eine Bedienperson weniger Kraft aufbringen muss.It is advantageous if an axis of rotation of the outer plate washer is inclined downward at an angle with respect to an axis of rotation of the inner plate washer. In this way, when side grinding from the rail, a higher holding or clamping force acts on the grinding machine. The grinding element is pulled more tightly to the rail head, which means that an operator has to apply less force.

Eine andere vorteilhafte Variante der Erfindung sieht vor, dass ein zweites Schienenführungssystem zwei Tellerscheiben, eine Führungsrolle und einen Führungshaken zum Anlegen an einen Schienenkopf umfasst. Diese Ausführungsvariante eignet sich besonders für den Einsatz in einem Weichenbereich oder bei Schienenkreuzungen.Another advantageous variant of the invention provides that a second rail guide system comprises two plate washers, a guide roller and a guide hook for placing on a rail head. This variant is particularly suitable for use in a switch area or at rail crossings.

Zudem ist es von Vorteil, wenn das jeweilige Schienenführungssystem drehbar auf einem Achsmitnehmer gelagert ist. Damit wird die Schleifmaschine im benötigten Winkel zur Schiene und in der von der Bedienperson gewünschten Position geführt.In addition, it is advantageous if the respective rail guide system is rotatably mounted on an axle driver. The grinding machine is thus guided at the required angle to the rail and in the position desired by the operator.

Dabei ist es sinnvoll, wenn der Achsmitnehmer mit einem um eine Mitnehmerachse verdrehbaren und wechselseitig montierbaren Führungsgriff verbunden ist. Die Schleifmaschine ist auf diese Weise einfach an die individuellen ergonomischen Ansprüche angepassbar und im gewünschten Winkel zur Schienen führbar. Durch die wechselseitige Montage des Führungsgriffs ist die Schleifmaschine sowohl für Rechts- als auch für Linkshänder nutzbar.It makes sense here if the axle driver is connected to a guide handle that can be rotated about a driver axis and mounted alternately. In this way, the grinding machine can be easily adapted to individual ergonomic requirements and guided at the desired angle to the rails. The alternating assembly of the guide handle means that the grinding machine can be used by both right-handed and left-handed people.

Als weitere Verbesserung ist der Führungsgriff über eine Arretiervorrichtung arretierbar. Dadurch wird der samt dem Achsmitnehmer verdrehbare Führungsgriff einfach in der gewünschten Position arretiert. Bei aktiver Arretiervorrichtung ist keine Winkeländerung zwischen Tragrahmen und Führungsgriff möglich und ein sicheres Arbeiten somit gewährleistet.As a further improvement, the guide handle can be locked using a locking device. As a result, the guide handle, which can be rotated together with the axle driver, is simply locked in the desired position. When the locking device is active, it is not possible to change the angle between the support frame and the guide handle, thus ensuring safe working.

In einer vorteilhaften Ausführung ist die Arretiervorrichtung als Lammellenbremse ausgeführt. Lamellenbremsen unterliegen nur einem sehr geringen Verschleiß und sind nahezu wartungsfrei, womit sie nicht nur sehr betriebssicher sind, sondern auch sehr langlebig und zuverlässig.In an advantageous embodiment, the locking device is designed as a multi-disc brake. Multi-disc brakes are subject to very little wear and tear and are almost maintenance-free, which means that they are not only very reliable, but also very durable and reliable.

Beschreibung der AusführungsformenDescription of the embodiments

Eine in Fig. 1 ersichtliche Schleifmaschine 1 zum Schleifen von Schienen 2 eines Gleises 3 weist einen sich in Gleislängsrichtung 4 erstreckenden Tragrahmen 5 auf, auf dem jeweils endseitig ein um eine Mitnehmerachse 6 drehbar gelagerter Achsmitnehmer 7 samt einer auf den Schienen 2 abrollbaren Schienenführung 8 angeordnet ist. An beiden Längsenden des Tragrahmens 5 ist jeweils auf dem Achsmitnehmer 7 ein bügelförmiger Führungsgriff 9 angeordnet, mit welchem der Tragrahmen 5 und ein auf dem Tragrahmen 5 angeordneter Antriebsmotor 10 samt Schleiforgan 11 (Schleifscheibe, Schleifstein) um die Mitnehmerachse 6 verschwenkbar sind.One in Fig. 1 The apparent grinding machine 1 for grinding rails 2 of a track 3 has a support frame 5 extending in the longitudinal direction 4 of the track, on which an axle driver 7 rotatably mounted about a driver axis 6, together with a rail guide 8 that can roll on the rails 2, is arranged at each end. At both longitudinal ends of the support frame 5, a bow-shaped guide handle 9 is arranged on the axle driver 7, with which the support frame 5 and a drive motor 10 arranged on the support frame 5 together with the grinding element 11 (grinding wheel, grindstone) can be pivoted about the driver axis 6.

Zusätzlich ist zwischen Tragrahmen 5 und Führungsgriff 9 eine Arretiervorrichtung 12 vorgesehen, die in Fig.1 beispielhaft als Lamellenbremse ausgeführt ist. Der Führungsgriff 9 kann von der Bedienperson in einen gewünschten Winkel zum Tragrahmen 5 verdreht und arretiert werden. Als Arretiervorrichtung 12 dient beispielsweise eine über einen Hebel 13 verstellbare Lammelenbremse. Außerdem ist der Führungsgriff 9 in Gleislängsrichtung 4 gesehen beidseitig am Tragrahmen 5 montierbar.In addition, a locking device 12 is provided between the support frame 5 and the guide handle 9, which is shown in FIG Fig. 1 is exemplified as a multi-disc brake. The guide handle 9 can be rotated and locked in a desired angle to the support frame 5 by the operator. A lamella brake that can be adjusted by means of a lever 13 is used as the locking device 12. In addition, the guide handle 9, viewed in the longitudinal direction 4 of the track, can be mounted on both sides of the support frame 5.

Die jeweilige Schienenführung 8 umfasst im Arbeitseinsatz eines von zwei verschiedenen, alternativ nutzbaren Schienenführungssysteme 14, 15. Während eines Schleifvorgangs ist entweder ein erstes Schienenführungssystem 14 oder ein zweites Schienenführungssystem 15 montiert. (in Fig. 1 sind zur Veranschaulichung beide Schienenführungssysteme dargestellt).The respective rail guide 8 comprises one of two different, alternatively usable rail guide systems 14, 15. During a grinding process, either a first rail guide system 14 or a second rail guide system 15 is installed. (in Fig. 1 both rail guide systems are shown for illustration).

Zusätzlich weist der Tragrahmen 5 an einem unteren Ende 16 zwei auf den Schienen 2 abrollbare Tragrollen 17 und endseitig jeweils einen Tragegriff 18 auf. Die Tragrollen 17 (Kopierrollen) rollen auf der Schienenoberfläche ab und bilden eine Oberflächenreferenz für das Schleiforgan 11.In addition, at a lower end 16, the support frame 5 has two support rollers 17 that can roll on the rails 2 and a handle 18 at each end on. The carrier rollers 17 (copier rollers) roll on the rail surface and form a surface reference for the grinding element 11.

Das Schleiforgan 11 ist über eine Höhenverstellung 19 in seiner Höhe variabel angeordnet. Beispielsweise dienen eine über ein Handrad 34 verdrehbare Spindel und ein einsprechendes Gegenstück als Höhenverstellung 19. Ein Drehwiderstand am Handrad 34 kann mittels eines auf ein Tellerfederpaket 21 wirkenden Verstellelements 20 eingestellt werden. Dazu ist das Verstellelement 20 beispielsweise als Überwurfmutter mit einer griffigen Oberfläche ausgebildet. Die variable Höhenverstellung 19 in Kombination mit den wechselbaren Schienenführungssystemen 14, 15 und dem einstellbaren Führungsgriff 9 ermöglicht ein besonders effiziente und ergonomische Arbeitsweise sowie eine flexible Einsetzbarkeit der Schleifmaschine 1.The grinding element 11 is arranged to be variable in height via a height adjustment 19. For example, a spindle that can be rotated via a handwheel 34 and a corresponding counterpart serve as a height adjustment 19. A rotational resistance on the handwheel 34 can be set by means of an adjusting element 20 acting on a disk spring assembly 21. For this purpose, the adjusting element 20 is designed, for example, as a union nut with a non-slip surface. The variable height adjustment 19 in combination with the exchangeable rail guide systems 14, 15 and the adjustable guide handle 9 enables a particularly efficient and ergonomic mode of operation and flexible use of the grinding machine 1.

Die Figuren 2 und 3 zeigen zwei Explosionsdarstellungen der Schienenführungen 8 mit den beiden Schienenführungssystemen 14, 15. Das jeweilige Schienenführungssystem 14, 15 wird mittels einer im Achsmitnehmer 7 geführten Schnellwechselvorrichtung 22 ausgetauscht. Rahmenseitig umfasst die Schnellwechselvorrichtung 22 eine drehbar gelagerte, beidseits offene Gleitbuchse 23 mit Innenverzahnung. Als Gegenstück der jeweiligen Schnellwechselvorrichtung 22 wird in diese Gleitbuchse 23 ein Zapfen 24 mit Außenverzahnung geschoben und arretiert.The Figures 2 and 3 show two exploded views of the rail guides 8 with the two rail guide systems 14, 15. The respective rail guide system 14, 15 is exchanged by means of a quick-change device 22 guided in the axle driver 7. On the frame side, the quick-change device 22 comprises a rotatably mounted sliding bush 23 open on both sides with internal teeth. As a counterpart of the respective quick-change device 22, a pin 24 with external teeth is pushed into this sliding bush 23 and locked.

Konkret umfasst das jeweilige Schienenführungssystem 14, 15 einen solchen Zapfen 24. Somit ist beispielsweise das erste Schienenführungssystem 14 an einer inneren Stirnseite der Gleitbuchse montierbar und das zweite Schienenführungssystem 15 ist an einer äußeren Seite der Gleitbuchse motierbar. Für den Transport oder Lagerung können somit auch beide Schienenführungssysteme gleichzeitig montiert sein. Eine Fixierung des jeweiligen Zapfens 24 erfolgt über eine Schraube, kann aber auch beispielsweise in einer nicht dargestellten Variante über einen Hebel erfolgen.Specifically, the respective rail guide system 14, 15 comprises such a pin 24. Thus, for example, the first rail guide system 14 can be mounted on an inner end face of the slide bushing and the second rail guide system 15 can be mounted on an outer side of the slide bushing. Both rail guide systems can therefore be installed at the same time for transport or storage. A fixation of the respective pin 24 takes place via a screw, but can also take place, for example, in a variant not shown, via a lever.

In Fig. 4 ist eine Detailansicht des ersten Schienenführungssystems 14 ersichtlich. Das erste Schienenführungssystem 14 umfasst lediglich eine innere Tellerscheibe 25 und eine äußere Tellerscheibe 26 zum Anlegen an einen Schienenkopf 27. Die beim Seitenschleifen des Schienenkopfes 27 äußere Tellerscheibe 26 weißt gegenüber der inneren Tellerscheibe 25 einen größeren Durchmesser auf. Jede Tellerscheibe 25, 26 ist um eine jeweilige Drehachse 28, 29 drehbar gelagert, wobei die Drehachse 29 der äußeren Tellerscheibe 26 gegenüber der Drehachse 28 der inneren Tellerscheibe 25 um einen Winkel α nach unten geneigt ist. Mittels der beiden Tellerscheiben 25, 26 kann der Schienenkopf 27 in einfacher Weise umfasst werden, um ein sicheres Führen der Schleifmaschine 1 zu gewährleisten. Die Neigung der äußeren Tellerscheibe 26 um den Winkel α verbessert dabei die vom Schienenkopf 27 auf die Schleifmaschine 1 wirkende Haltekraft, wodurch eine Bedienperson beim Seitenschleifen entlastet wird.In Fig. 4 a detailed view of the first rail guide system 14 can be seen. The first rail guide system 14 only comprises an inner cup washer 25 and an outer cup washer 26 for contact a rail head 27. The outer plate washer 26 when the rail head 27 is grinded on the side has a larger diameter than the inner plate washer 25. Each plate washer 25, 26 is rotatably mounted about a respective axis of rotation 28, 29, the axis of rotation 29 of the outer plate washer 26 being inclined downward at an angle α relative to the axis of rotation 28 of the inner plate washer 25. The rail head 27 can be easily encompassed by means of the two cup washers 25, 26 in order to ensure reliable guidance of the grinding machine 1. The inclination of the outer plate washer 26 by the angle α improves the holding force acting from the rail head 27 on the grinding machine 1, as a result of which an operator is relieved during side grinding.

In den Figuren 5 und 6 sind zwei Detailansichten des zweiten Schienenführungssystems 15 ersichtlich. Das zweite Schienenführungssystem 15 umfasst zwei Tellerscheiben 30, eine Führungsrolle 31 und einen Führungshaken 32 zum Anlegen an den Schienenkopf 27. Die Tellerscheiben 30 sind ebenfalls auf zueinander im Winkel angeordneten Achsen drehbar gelagert. Das zweite Schienenführungssystem 15 ist in verschiedenen Stellungen an eine Schiene 2 oder an andere Elemente des Gleises 3 (Radlenker, Führungsschiene) anlegbar, wodurch eine effiziente Bearbeitung von Weichen oder Schienenkreuzungen erleichtert wird.In the Figures 5 and 6 two detailed views of the second rail guide system 15 can be seen. The second rail guide system 15 comprises two plate washers 30, a guide roller 31 and a guide hook 32 for placing on the rail head 27. The plate washers 30 are also rotatably mounted on axes arranged at an angle to one another. The second rail guide system 15 can be placed in various positions on a rail 2 or on other elements of the track 3 (wheel guide, guide rail), which facilitates efficient processing of switches or rail crossings.

Die Figuren 7 bis 9 zeigen verschieden Einsatzmöglichkeiten der Schleifmaschine 1 mit montiertem zweitem Schienenführungssystem 15. In Fig. 7 ist die Schleifmaschine 1 aufrecht auf dem Schienenkopf 27 auf den Tragrollen 17 abgestützt. Führungshaken 32 und Führungsrolle 31 des zweiten Schienenführungssystems 15 umfassen den Schienenkopf 27. Diese Stellung eignet sich besonders für einen Kopfschliff der Schiene 2.The Figures 7 to 9 show various possible uses of the grinding machine 1 with the second rail guide system 15 installed. In Fig. 7 the grinding machine 1 is supported upright on the rail head 27 on the support rollers 17. The guide hook 32 and guide roller 31 of the second rail guide system 15 encompass the rail head 27. This position is particularly suitable for a head grinding of the rail 2.

In Fig. 8 ist die Schleifmaschine 1 ebenfalls mittels Tragrollen 17 aufrecht auf dem Schienenkopf 27 abgestützt. Das zweite Schienenführungssystem 15 ist jedoch gegenüber der Stellung in Fig. 7 um 180° verdreht angeordnet. Diese Stellung eignet sich besonders im Weichenbereich. Eine der Tellerscheiben 30 stützt sich dabei auf einem Radlenker 33 ab.In Fig. 8 the grinding machine 1 is also supported upright on the rail head 27 by means of support rollers 17. However, the second rail guide system 15 is opposite to the position in Fig. 7 Arranged rotated by 180 °. This position is particularly suitable for turnouts. One of the cup washers 30 is supported on a wheel guide 33.

In Fig. 9 ist die Schleifmaschine 1 samt Führungsgriff 9 gegenüber den Positionen in den Figuren 7 und 8 um 90° verdreht auf der Schiene 2 angeordnet. Sicher geführt wird die Schleifmaschine 1 dabei mittels der an der Schiene 2 angelegten Tragrollen 17 und Führungsrollen 31. Konkret wird die Schleifmaschine 1 über die Tragrollen 17 seitlich auf dem Schienenkopf 27 abgestützt. In dieser Stellung wird einen Seitenschliff der Schiene 2 durchgeführt.In Fig. 9 is the grinding machine 1 including the guide handle 9 opposite the positions in the Figures 7 and 8 Rotated by 90 ° arranged on the rail 2. The grinding machine 1 is safely guided by means of the support rollers 17 and guide rollers 31 placed on the rail 2. Specifically, the grinding machine 1 is supported laterally on the rail head 27 via the support rollers 17. In this position, a side grinding of the rail 2 is carried out.
