The inclination of the outer cup 26 by the angle α thereby improves the from

Schienenkopf 27 auf die Schleifmaschine 1 wirkende Haltekraft, wodurch eine Bedienperson beim Seitenschleifen entlastet wird.  Rail head 27 acting on the grinding machine 1 holding force, whereby an operator is relieved during side grinding.

[25] In den Figuren 5 und 6 sind zwei Detailansichten des zweiten  [25] In FIGS. 5 and 6 are two detailed views of the second

Schienenführungssystems 15 ersichtlich. Das zweite  Rail guide system 15 can be seen. The second

Schienenführungssystem 15 umfasst zwei Tellerscheiben 30, eine  Rail guiding system 15 comprises two dishwashers 30, one

Führungsrolle 31 und einen Führungshaken 32 zum Anlegen an den  Guide roller 31 and a guide hook 32 for application to the

Schienenkopf 27. Die Tellerscheiben 30 sind ebenfalls auf zueinander im Winkel angeordneten Achsen drehbar gelagert. Das zweite  Rail head 27. The disk washers 30 are also rotatably mounted on mutually angularly arranged axes. The second

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  Rail guide system 15 can be applied in different positions to a rail 2 or to other elements of the track 3 (track guide, guide rail), whereby an efficient processing of switches or

Schienenkreuzungen erleichtert wird.  Rail crossings is facilitated.

[26] Die Figuren 7 bis 9 zeigen verschieden Einsatzmöglichkeiten der  [26] Figures 7 to 9 show different uses of the

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.  Grinding machine 1 with mounted second rail guide system 15. In Fig. 7, the grinding machine 1 is supported upright on the rail head 27 on the support rollers 17. Guide hook 32 and guide roller 31 of the second rail guide system 15 comprise the rail head 27. This position is particularly suitable for a head finish of the rail second

[27] 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. 9 ist die Schleifmaschine 1 samt Führungsg ff 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. 8, the grinding machine 1 is also supported by means of support rollers 17 upright on the rail head 27. However, the second rail guide system 15 is arranged rotated in relation to the position in Fig. 7 by 180 °. This position is particularly suitable in the points area. One of the plate discs 30 is based on a Radlenker 33 from. In Fig. 9, the grinding machine 1 including Führungsg ff 9 is rotated relative to the positions in Figures 7 and 8 by 90 ° on the rail 2. The grinding machine 1 is reliably guided by means of the support rollers 17 and guide rollers 31 applied to 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 performed.
