Abstract

The profiling machine (1) is rolled along the rail (47) supported on flanged wheels (22) at each end. Swivel mountings (8) support a grinding frame (3) to position a grinding head onto the rail profile. Guide rollers (4) on the grinding head limit the amount of rail material taken off by the grinding head. The rollers tilt with the frame alignment about an axis parallel to the rail. The two flanges on each support wheel provide a vertical reference for grinding the two flanges of the rail with the appropriate flange brought into contact with the side of the rail by lateral movement of the wheel. The swivel action is controlled by a geared drive (33,34) on the swivel mounting. The differences in height setting, w.r.t. the rail, of the rollers and the flanged wheels control the amount of material removed by the grinding head.

Description

Die Erfindung betrifft eine Vorrichtung zum Schleifen von Schienen eines Gleises, mit einem über Tastrollen mit Drehachsen auf einer Schiene abrollbaren, ein relativ zur Schiene verstellbares Schleiforgan aufweisenden Tragrahmen, der um eine in Schienenlängsrichtung verlaufende Schwenkachse schwenkbar an einem Aggregatrahmen mit auf den Schienen abrollbaren Führungsrollen gelagert ist, wobei sowohl Tast- als auch Führungsrollen jeweils eine zum Abrollen auf der Schiene vorgesehene Abrollfläche aufweisen, und ein zur Anlage an eine vertikale Seitenfläche der Schiene ausgebildetes Führungsorgan in bezug auf den Tragrahmen distanzierbar mit dem Aggregatrahmen verbunden ist.The invention relates to a device for grinding rails of a track, with a support frame that can be rolled on a rail by means of feeler rollers with rotary axes and has a grinding member that is adjustable relative to the rail, which is pivotably mounted about a pivot axis running in the longitudinal direction of the rail on an assembly frame with guide rollers that can be rolled on the rails is, both touch and guide rollers each have a rolling surface provided for rolling on the rail, and a guide member designed to bear against a vertical side surface of the rail is connected to the unit frame so that it can be distanced from the supporting frame.

Eine derartige Vorrichtung ist aus der DE 1 274 610 A bekannt. Diese von Hand verfahrbare Schienenschleifmaschine weist einen mittels Tastrollen am Schienenkopf aufliegenden Tragrahmen auf, an dem ein Schleiforgan samt einem Antriebsmotor gelagert und an Hand eines Spindelantriebes relativ zur Schiene verstellbar ist. Der Tragrahmen ist an seinen beiden Längsenden verschwenkbar mit einem Aggregatrahmen verbunden, der über Führungsrollen mit horizontalen Drehachsen auf der Schiene abgestützt ist. Diese mit Spurkränzen ausgestatteten Führungsrollen sind jeweils in einem gabelförmigen Rollenträger gelagert, der in Führungsleisten am Aggregatrahmen relativ zu diesem in Richtung der Drehachsen der Rollen verschiebbar angeordnet ist. Die aus Tragrahmen und Aggregatrahmen gebildete Einheit ist in Gleisquerrichtung in verschiedene Positionen verstellbar und in diesen an Hand von Spannmuttern an den - formschlüssig mit dem Schienenkopf in Eingriff verbleibenden - Führungsrollen fixierbar. Die Verbindung von Trag- und Aggregatrahmen erfolgt über zwei Schwingen, die jeweils über einen in Schienenlängsrichtung ausgerichteten Drehzapfen am Tragrahmen und über einen weiteren, zum ersten versetzt angeordneten Drehzapfen am Aggregatrahmen befestigt sind.Such a device is known from DE 1 274 610 A. This manually grindable rail grinding machine has a support frame resting on the rail head by means of feeler rollers, on which a grinding member together with a drive motor is mounted and can be adjusted relative to the rail by means of a spindle drive. The support frame is pivotally connected at its two longitudinal ends to an assembly frame which is supported on the rail by guide rollers with horizontal axes of rotation. These guide rollers, which are equipped with wheel flanges, are each mounted in a fork-shaped roller carrier, which is arranged in guide rails on the unit frame so as to be displaceable relative to the latter in the direction of the axes of rotation of the rollers. The unit, which consists of a support frame and unit frame, can be adjusted to various positions in the transverse direction of the track and can be fixed in it using tension nuts on the guide rollers that remain in positive engagement with the rail head. The connection between the support frame and the assembly frame is made via two rockers, each of which is attached to the assembly frame by means of a pivot pin oriented in the longitudinal direction of the rail and via a further pivot pin arranged offset to the first.

In der DE 2 908 244 A ist eine Schleifvorrichtung mit einem sich in Schienen längsrichtung erstreckenden Rahmen beschrieben, der an beiden Längsenden um eine parallel zur Schiene verlaufende Achse verschwenkbar mit je einem Stützfuß verbunden ist und damit beidseits der Schleifstelle auf der zu bearbeitenden Schiene festgeklemmt wird. Eine Verriegelungseinrichtung gestattet das Fixieren des Rahmens in jeder gewählten Verschwenkposition. Auf einer am Rahmen montierten Längsführung ist ein das Schleiforgan aufweisender Schlitten in Schienenlängsrichtung verschiebbar gelagert, wobei diese Längsführung mit Tastern ausgestattet ist, die während der Querverschwenkung des Rahmens dem Schienenprofil folgen bzw. dieses kopieren. Um die hierbei erforderlichen Abstandsänderungen der Längsführung mitsamt dem Schleiforgan in bezug auf die Schwenkachse zu ermöglichen, ist die Längsführung über senkrecht zur Schienenlängsrichtung verlaufende Säulen gleitend auf dem Rahmen gelagert und mit Rückstellfedern versehen.DE 2 908 244 A describes a grinding device with a frame extending in the longitudinal direction of the rails, which at both longitudinal ends is pivotally connected to a support foot about an axis running parallel to the rail and is thus clamped on both sides of the grinding point on the rail to be machined. A locking device allows the frame to be fixed in any selected pivot position. On a longitudinal guide mounted on the frame, a slide having the grinding member is slidably mounted in the longitudinal direction of the rail, this longitudinal guide being equipped with buttons which follow or copy the rail profile during the transverse pivoting of the frame. In order to enable the necessary changes in the distance of the longitudinal guide together with the grinding element with respect to the pivot axis, the longitudinal guide is slidably mounted on the frame via columns running perpendicular to the longitudinal direction of the rail and provided with return springs.

Gemäß WO 91/08343 ist ebenfalls eine an einer Schiene anklemmbare Vorrichtung bekannt, bei der ein senkrecht zur Schiene verstellbares Schleiforgan auf einer parallel zur Schiene verlaufenden, als Träger fungierenden Längsführung verschiebbar gelagert ist. Dieser Träger ist an seinen beiden Enden in einer zum Idealprofil der Schiene im wesentlichen parallel verlaufenden Kurvenbahn geführt und zusätzlich mittels Rollen auf der Schiene abgestützt, die quer über den Schienenkopf abrollen und so die Schleifscheibe im gleichen Abstand vom tatsächlichen Schienenprofil halten.According to WO 91/08343, a device that can be clamped to a rail is also known, in which a grinding element that is adjustable perpendicular to the rail is slidably mounted on a longitudinal guide that runs parallel to the rail and acts as a carrier. This carrier is guided at its two ends in a curved path which runs essentially parallel to the ideal profile of the rail and is additionally supported on the rail by means of rollers which roll across the rail head and thus keep the grinding wheel at the same distance from the actual rail profile.

Bei einer weiteren, durch die DE 43 16 252 A1 bekannten gleisverfahrbaren Schienenschleifmaschine ist das Schleiforgan auf einer Schwenkkonsole befestigt, die um eine in Schienenlängsrichtung verlaufende Achse rotierbar mit einem Liftrahmen verbunden ist. Dieser ist seinerseits höhenverstellbar auf einem Zustellschlitten gelagert, der auf einem Tragrahmen senkrecht zur Schienenlängsrichtung horizontal verschiebbar angeordnet ist. Der Tragrahmen schließlich ist auf einem auf den Schienen abrollbaren Fahrgestellrahmen montiert. Um das Schleiforgan auf einen bestimmten Punkt des zu schleifenden Schienenprofiles einzustellen, sind drei separat voneinander an Hand von eigenen Hydraulik- oder Spindelantrieben durchführbare Bewegungen erforderlich, nämlich Querverstellung, Höhenverstellung und Verschwenkung des Schleiforganes. Eine ähnliche Anordnung ist auch in der US 4 993 193 geoffenbart.In a further track-traveling rail grinding machine known from DE 43 16 252 A1, the grinding member is attached to a swivel bracket which is rotatably connected to an elevator frame about an axis running in the longitudinal direction of the rail. This in turn is height-adjustable mounted on a feed carriage which is arranged horizontally displaceable on a support frame perpendicular to the longitudinal direction of the rail. Finally, the support frame is mounted on a chassis frame that can be rolled off the rails. In order to adjust the grinding element to a specific point on the rail profile to be ground, three movements which can be carried out separately from one another using their own hydraulic or spindle drives are required, namely transverse adjustment, height adjustment and pivoting of the grinding element. A similar arrangement is also disclosed in US 4,993,193.

Die Aufgabe der vorliegenden Erfindung besteht nun in der Schaffung einer Vorrichtung der eingangs genannten Art, die ein problemloses und genaues Kopieren des Schienenkopfprofiles in Kombination mit höchstem Bedienungskomfort und Sicherheit für das Arbeitspersonal ermöglicht.The object of the present invention is now to provide a device of the type mentioned at the outset, which enables problem-free and exact copying of the rail head profile in combination with maximum ease of use and safety for the working personnel.

Diese Aufgabe wird mit einer gattungsgemäßen Vorrichtung dadurch gelöst, daß - bei Horizontalstellung der Drehachsen der Tastrollen parallel zu Drehachsen der Führungsrollen - ein durch Kontakt der Abrollfläche mit der Schiene definierter Rollenaufstandspunkt der Führungsrolle in bezug auf einen Rollenaufstandspunkt der Tastrolle unter höherer Positionierung distanziert angeordnet ist, und daß ein Verschwenkantrieb zum Verschwenken des Aggregatrahmens relativ zum Tragrahmen vorgesehen ist.This object is achieved with a device of the generic type in that - when the axes of rotation of the feeler rollers are in a horizontal position parallel to the axes of rotation of the guide rollers - a roller contact point of the guide roller defined by contact of the rolling surface with the rail is arranged at a greater distance from a contact point of the contact roller with higher positioning, and that a pivoting drive is provided for pivoting the assembly frame relative to the support frame.

Diese spezielle Anordnung der Tast- und Führungsrollen zueinander ermöglicht es, sowohl die horizontale Lauffläche als auch beide vertikale Seitenflächen eines Schienenkopfes problemlos und mit hoher Präzision zu bearbeiten, wobei in Verbindung mit dem Verschwenkantrieb auch ein Höchstmaß an Ergonomie gewährleistet ist. Beim Schleifen der Lauffläche und der oberen Schienenkopfkanten werden die als Kopierrollen fungierenden Tastrollen in ihrer Verschwenkbewegung um die Schwenkachse in keiner Weise beeinträchtigt oder behindert, da die Führungsrollen hierbei keinen Kontakt mit der Schiene haben und sich die gesamte Vorrichtung lediglich über die besagten Tastrollen auf der Schiene abstützt. Dadurch kann das Schienenprofil zu beiden Seiten der Schleifstelle genauestens verfolgt und an der Schleifstelle selbst durch das Schleiforgan kopiert werden, um beispielsweise einen geschweißten Schienenstoß plan zu schleifen. Wird der Tragrahmen zum Schleifen der Schienenkopfseitenflächen ganz zur Seite verschwenkt, so ermöglicht die - in bezug auf den Rollenaufstandspunkt der Tastrolle - höhere Positionierung der Rollenaufstandspunkte der Führungsrollen ein selbsttätiges bzw. automatisches Absenken der Vorrichtung, bis die Führungsrollen auf der Schiene aufliegen. Diese Absenkung bietet den Vorteil, daß das Schleiforgan besser auf der zu schleifenden Seitenfläche der Schiene plazierbar ist und der Schleifbereich weiter nach unten ausgedehnt werden kann. Gleichzeitig verhindert das Führungsorgan ein Abrutschen der Vorrichtung von der Schiene ungeachtet der Verschwenkstellung des Schleiforganes. Die Bedienungsperson kann sich also - weitgehend unbelastet von Vorsichtsmaßnahmen - auf das Balanzieren der Vorrichtung auf der Schiene und auf die Bedienung des Verschwenkantriebes konzentrieren, wodurch alle weiteren Bewegungen des Trag- und Aggregatrahmens relativ zueinander automatisch ausgelöst werden.This special arrangement of the feeler and guide rollers to each other makes it possible to machine both the horizontal running surface and both vertical side surfaces of a rail head without any problems and with high precision, whereby the highest degree of ergonomics is also guaranteed in connection with the swivel drive. When grinding the tread and the upper rail head edges, the feeler rollers acting as copying rollers are in no way impaired or hindered in their pivoting movement about the pivot axis, since the guide rollers have no contact with the rail here and the entire device is only on the said feeler rollers on the rail supports. As a result, the rail profile can be tracked precisely on both sides of the grinding point and copied at the grinding point itself by the grinding element, for example to grind a welded rail joint flat. If the support frame is pivoted completely to the side to grind the rail head side surfaces, the higher positioning of the roller contact points of the guide rollers with respect to the roller contact point of the feeler roller enables the device to be lowered automatically or automatically until the guide rollers rest on the rail. This lowering has the advantage that the grinding member can be placed better on the side surface of the rail to be ground and the grinding area can be extended further downwards. At the same time, the guide element prevents the Device from the rail regardless of the pivoting position of the grinding element. The operator can therefore concentrate on balancing the device on the rail and on the operation of the pivoting drive, largely unencumbered by precautionary measures, whereby all further movements of the support and assembly frame are automatically triggered relative to one another.

The support frame 3 is rotatably connected at its two longitudinal ends about a pivot axis 7 which runs in the longitudinal direction of the rail and is formed from a shaft 6 to an assembly frame 8 which is provided with a bracket 9 which projects upwards and bridges the support frame 3.

Auf einer am Aggregatrahmen 8 befestigten Konsole 10 befindet sich ein Antriebsmotor 11, der über eine flexible Antriebswelle 12 mit einem auf dem Tragrahmen 3 vorgesehenen Schleifaggregat 13 in Verbindung steht. Dieses setzt sich aus einem mittig zwischen den Tastrollen 4 am Tragrahmen 3 angeordneten Schleiforgan 14 und einem Winkelgetriebe 15 zusammen, an das die Antriebswelle 12 angeschlossen ist.

The grinding member 14 is designed as a cup wheel 16 which rotates about a rotation axis 18 which runs perpendicular to the longitudinal direction of the rail and which is acted upon by the bevel gear 15 by means of a V-belt 17. The cup wheel 16 can be advanced in the direction of its axis of rotation 18 vertically with respect to the rail 2 to be machined by means of an adjustment drive 20, this - preferably electrically operated - adjustment movement being remotely controllable by a button 19 mounted in the upper region of the bracket 9.

Wie im weiteren in Fig. 3 und 4 noch deutlicher erkennbar, ist der Aggregatrahmen 8 an seinen Längsenden mit je einer Führungsrolle 22 ausgestattet. Diese Führungsrollen 22 mit horizontalen bzw. zur Gleisebene parallelen Drehachsen 23 weisen jeweils in Richtung der Drehachse 23 voneinander distanzierte Spurkränze 21 auf, die die Funktion von - zur Anlage an eine vertikale Seitenfläche 39 der Schiene 2 ausgebildeten - Führungsorganen 40 haben. Diese sind in bezug auf den Tragrahmen 3 verstellbar bzw. zu diesem distanzierbar ausgebildet. Zu diesem Zweck sind die Führungsrollen 22 entlang einer in Richtung der Drehachsen 23 verlaufenden Querführung 24 relativ zum Aggregatrahmen 8 verschiebbar an diesem gelagert. Die Querführung 24 besteht aus einer Gleitmanschette 25, die mit Achslagern 26 der Führungsrolle 22 verbunden ist und auf einem im Querschnittsprofil vierkantförmigen Gleitträger 27 frei verschiebbar bzw. schwimmend gelagert ist. Der Gleitträger 27 ist in einem auf einer Seite offenen Gehäuse 28 untergebracht, an dessen Unterseite sich ein Lagerblock 29 zur Aufnahme der mit dem Tragrahmen 3 verbundenen Welle 6 befindet.As can be seen even more clearly in FIGS. 3 and 4, the unit frame 8 is equipped with a guide roller 22 at each of its longitudinal ends. These guide rollers 22, with horizontal axes of rotation 23 or axes of rotation parallel to the track plane, each have wheel flanges 21 which are spaced apart from one another in the direction of the axis of rotation 23 and which have the function of guide members 40 which are designed to bear against a vertical side surface 39 of the rail 2. These can be adjusted with respect to the support frame 3 or can be distanced from it. For this purpose, the guide rollers 22 are slidably mounted on the unit frame 8 along a transverse guide 24 running in the direction of the axes of rotation 23. The transverse guide 24 consists of a sliding sleeve 25 which with the axle bearings 26 Guide roller 22 is connected and is mounted on a square cross-sectional sliding support 27 freely displaceable or floating. The slide carrier 27 is accommodated in a housing 28 which is open on one side and on whose underside there is a bearing block 29 for receiving the shaft 6 connected to the support frame 3.

Ein im Inneren des Gleitträgers 27 befindliches Druckelement 41 in Form einer Feder 42 ist mit der Gleitmanschette 25 verbunden und bestrebt, die Führungsrolle 22 mittig in bezug auf die Querführung 24 bzw. bezüglich des Aggregatrahmens 8 zentriert zu halten (siehe Fig. 5). Sowohl die Tastrollen 4 als auch die Führungrollen 22 weisen eine zum Abrollen auf der Schiene 2 vorgesehene und mit 43 bzw. 44 bezeichnete Abrollfläche auf. Durch den Kontakt dieser Abrollfläche 43 der Tastrolle 4 mit der Schiene 2 wird ein Rollenaufstandspunkt 45 definiert, während ein entsprechender Rollenaufstandspunkt der Führungsrolle 22 das Bezugszeichen 46 trägt. Wie in Fig. 3 und insbesondere in Fig. 5 zu sehen, ist - bei einer horizontalen Ausrichtung der Drehachsen 5 der Tastrollen 4 parallel zu den Drehachsen 23 der Führungsrollen 22 - der Rollenaufstandspunkt 46 der Führungsrolle 22 in bezug auf den Rollenaufstandspunkt 45 der Tastrolle 4 höher positioniert bzw. vertikal von diesem distanziert angeordnet.A pressure element 41 in the form of a spring 42 located in the interior of the slide carrier 27 is connected to the slide sleeve 25 and endeavors to keep the guide roller 22 centered with respect to the transverse guide 24 or with respect to the unit frame 8 (see FIG. 5). Both the feeler rollers 4 and the guide rollers 22 have a rolling surface which is provided for rolling on the rail 2 and is designated 43 and 44, respectively. The contact of this rolling surface 43 of the feeler roller 4 with the rail 2 defines a roller contact point 45, while a corresponding roller contact point of the guide roller 22 bears the reference symbol 46. As can be seen in FIG. 3 and in particular in FIG. 5, with a horizontal orientation of the axes of rotation 5 of the feeler rollers 4 parallel to the axes of rotation 23 of the guide rollers 22, the point of contact with the roller 46 of the guide roller 22 with respect to the point of contact with the roller 45 of the feeler roller 4 positioned higher or spaced vertically from this.

Zur Verschwenkung des Tragrahmens 3 relativ zum Aggregatrahmen 8 ist ein Verschwenkantrieb 30 vorgesehen, der im Bereich der einen Verbindungsstelle der beiden Rahmen 3,8 angeordnet und als Kegelradgetriebe 31 ausgebildet ist. Dieses setzt sich aus einem am Tragrahmen 3 befestigten, entlang seines Umfanges einen Zahnkranz 32 aufweisenden Kegelrad 33 sowie einem mit dem Aggregatrahmen 8 verbundenen Antriebsrad 34 zusammen. Das als Halbkreis geformte Kegelrad 33 ist in einer senkrecht zur Schienenlängsrichtung verlaufenden Vertikalebene koaxial zur Schwenkachse 7 bzw. zur Welle 6 angeordnet, während das - einen im Vergleich dazu viel kleineren Durchmesser aufweisende - Antriebsrad 34 mit seiner Achse 35 im rechten Winkel zur Schwenkachse 7 in einer Halterung 36 des Aggregatrahmens 8 montiert ist. An Hand einer am Bügel 9 befestigten Kurbel 37 ist das Antriebsrad 34 über einen biegsamen Schaft 38 in Drehung versetzbar, wodurch die Verschwenkung des Tragrahmens 3 ausgelöst bzw. gesteuert wird.For pivoting the support frame 3 relative to the unit frame 8, a pivoting drive 30 is provided, which is arranged in the area of the one connection point of the two frames 3, 8 and is designed as a bevel gear 31. This is composed of a bevel gear 33 fastened to the supporting frame 3 and having a ring gear 32 along its circumference, and a drive gear 34 connected to the assembly frame 8. The bevel gear 33, which is shaped as a semicircle, is arranged in a vertical plane running perpendicular to the longitudinal direction of the rail coaxially with the swivel axis 7 or with the shaft 6, while the drive wheel 34 - which has a much smaller diameter in comparison - has its axis 35 at right angles to the swivel axis 7 in a bracket 36 of the assembly frame 8 is mounted. On the basis of a crank 37 fastened to the bracket 9, the drive wheel 34 can be set in rotation via a flexible shaft 38, as a result of which the pivoting of the supporting frame 3 is triggered or controlled.

Im Arbeitseinsatz wird die Vorrichtung auf einer Schiene 2 von Hand verfahren und an der Schleifstelle hin- und herbewegt. Der Aggregatrahmen 8 bzw. der Bügel 9 bleibt dabei immer in lotrechter Stellung und wird - im Gegensatz zum Tragrahmen 3 - nicht gekippt. Dies bietet den Vorteil einer ergonomisch richtigen, bequem aufrecht stehenden Arbeitsweise für den Bediener, der alle Einstellvorgänge an Hand der oben am Bügel 9 angeordneten Bedienungselemente durchführen kann. Zudem kann der Antriebsmotor 11, da er nicht gekippt wird, auch als Viertaktmotor mit besseren Emissionswerten und geringerer Lärmentwicklung ausgeführt sein.In work, the device is moved on a rail 2 by hand and moved back and forth at the grinding point. The unit frame 8 or the bracket 9 always remains in the vertical position and - in contrast to the support frame 3 - is not tilted. This offers the advantage of an ergonomically correct, comfortably upright working method for the operator, who can carry out all adjustment processes using the operating elements arranged at the top of the bracket 9. In addition, since the drive motor 11 is not tilted, it can also be designed as a four-stroke engine with better emission values and less noise.

Beim Schleifen der horizontalen Lauffläche 47 einer Schiene 2 befindet sich die Vorrichtung 1 in der in Fig. 1 und 5 gezeigten Stellung. Der Tragrahmen 3 liegt auf der Schiene 2 über die Tastrollen 4 auf, deren Drehachsen 5 nun horizontal ausgerichtet sind. Der Aggregatrahmen 8 ruht über die Querführung 24 ebenfalls auf den Tastrollen 4, während die Führungsrollen 22 aufgrund der höheren Positionierung ihrer Rollenaufstandspunkte 46 nicht auf der Schiene 2 aufliegen. Die Spurkränze 21 der Führungsrollen 22 sind so dimensioniert, daß sie sich dabei über die oberen Schienenkopfkanten nach unten erstrecken und als Führungsorgane 40 verhindern, daß die Vorrichtung 1 seitlich von der Schiene 2 abrutschen kann. Der Bediener regelt den Vorschub des Schleiforganes 14 bzw. der Topfscheibe 16 mittels des Verstellantriebes 20 über die Taste 19, wobei das Eigengewicht der Vorrichtung 1 den für das Schleifen nötigen Anpreßdruck erzeugt.When grinding the horizontal running surface 47 of a rail 2, the device 1 is in the position shown in FIGS. 1 and 5. The support frame 3 rests on the rail 2 via the feeler rollers 4, the axes of rotation 5 of which are now aligned horizontally. The unit frame 8 also rests on the feeler rollers 4 via the transverse guide 24, while the guide rollers 22 do not rest on the rail 2 due to the higher positioning of their roller contact points 46. The flanges 21 of the guide rollers 22 are dimensioned such that they extend downward over the upper rail head edges and, as guide members 40, prevent the device 1 from slipping off the rail 2 laterally. The operator controls the feed of the grinding member 14 or the cup wheel 16 by means of the adjustment drive 20 via the key 19, the weight of the device 1 generating the contact pressure required for grinding.

Soll nun eine Schienenkopfkante oder - wie in Fig. 2 und 6 zu sehen - eine der vertikalen Seitenflächen 39 eines Schienenkopfes 52 bearbeitet werden, so ist dazu lediglich eine Verschwenkung des Tragrahmens 3 an Hand des über die Kurbel 37 bedienbaren Verschwenkantriebes 30 erforderlich. Die Rotation der Welle 6 um die Schwenkachse 7 führt zu einem Kippen der Tastrollen 4, die in ihrer Funktion als Kopierrollen dem Querschnittsprofil des Schienenkopfes 52 folgen. Dadurch wird automatisch auch eine Verschiebung des Tragrahmens 3 und des mit diesem über die Welle 6 gekoppelten Aggregatrahmens 8 quer zur Schienenlängsrichtung ausgelöst. Die Führungsrollen 22 bleiben dabei auf Grund der Spurkränze 21 in ihrer bezüglich der Schiene 2 zentrierten Stellung mit horizontaler Ausrichtung der Drehachsen 23. Die daraus resultierende Querverstellung der Gleitmanschette 25 relativ zum Gleitträger 27 der Querführung 24 bewirkt eine Kompression des Druckelementes 41 auf der der Schleifstelle gegenüberliegenden Seite und dadurch in weiterer Folge die Erzeugung eines Anpreßdruckes des Schleiforganes 14 auf die Seitenfläche 39 des Schienenkopfes 52. Dieser Anpreßdruck nimmt proportional zur Verschwenkung des Tragrahmens 3 zu und ersetzt dadurch den zwangsweise abnehmenden, durch das Eigengewicht der Vorrichtung erzeugten Anpreßdruck automatisch.If a rail head edge or - as can be seen in FIGS. 2 and 6 - one of the vertical side surfaces 39 of a rail head 52 is to be machined, then only a pivoting of the support frame 3 using the pivot drive 30 that can be operated via the crank 37 is required. The rotation of the shaft 6 about the pivot axis 7 leads to a tilting of the feeler rollers 4 which, in their function as copying rollers, follow the cross-sectional profile of the rail head 52. As a result, a displacement of the support frame 3 and of the unit frame 8 coupled to it via the shaft 6 is also triggered transversely to the longitudinal direction of the rail. The guide rollers 22 remain due to the flanges 21 in terms of the rail 2 centered position with horizontal alignment of the axes of rotation 23. The resulting transverse adjustment of the sliding sleeve 25 relative to the slide carrier 27 of the transverse guide 24 causes compression of the pressure element 41 on the side opposite the grinding point and consequently the generation of a contact pressure of the grinding member 14 onto the side surface 39 of the rail head 52. This contact pressure increases proportionally to the pivoting of the support frame 3 and thereby automatically replaces the contact pressure which is automatically reduced due to the weight of the device.

Bei Erreichen der größtmöglichen Verschwenkung und dadurch bedingten Querverstellung des Tragrahmens 3 nehmen die Drehachsen 5 der Tastrollen 4 eine etwa vertikale Position ein (Fig. 6). Dies ermöglicht ein Absenken der gesamten Vorrichtung 1 in vertikaler Richtung um jene Distanz, um die der Rollenaufstandspunkt 46 der Abrollfläche 44 der Führungsrolle 22 in der Ausgangsposition von der Lauffläche 47 der Schiene 2 distanziert war. Die strichpunktierte Linie 48 in Fig. 6 zeigt die bogenförmige Bahn, die die Schwenkachse 7 zwischen den beiden möglichen Extremstellungen beschreibt. Da beide Seitenflächen 39 des Schienenkopfes 52 gleichermaßen vom Schleiforgan 14 erreichbar sind, erübrigt sich ein Umdrehen der Vorrichtung 1 auf der Schiene 2.When the greatest possible pivoting and consequent transverse adjustment of the support frame 3 is reached, the axes of rotation 5 of the feeler rollers 4 assume an approximately vertical position (FIG. 6). This enables the entire device 1 to be lowered in the vertical direction by the distance by which the roller contact point 46 of the rolling surface 44 of the guide roller 22 was distanced from the running surface 47 of the rail 2 in the starting position. The dash-dotted line 48 in FIG. 6 shows the arcuate path that describes the pivot axis 7 between the two possible extreme positions. Since both side surfaces 39 of the rail head 52 are equally accessible from the grinding member 14, there is no need to turn the device 1 on the rail 2.

Bei der in Fig. 7 dargestellten Variante einer Vorrichtung zum Schienenschleifen sind funktionsgleiche Teile mit denselben Bezugszeichen wie in den Fig. 1 bis 6 versehen. Diese Vorrichtung 49 unterscheidet sich von der bereits beschriebenen dadurch, daß das Führungsorgan 40 nicht der zu bearbeitenden Schiene 2 zugeordnet ist, sondern als auf der gegenüberliegenden Schiene 2 abrollbare Doppelspurkranzrolle 50 ausgebildet ist. Diese ist wieder über eine Querführung 24 mit dem Aggregatrahmen 8 verbunden und relativ zu diesem querverstellbar. Die Querführung 24 ist als teleskopisch verlänger- bzw. verkürzbarer Balken 51 ausgebildet und mit einem Druckelement 41 versehen. Die am Aggregatrahmen 8 angeordneten Führungsrollen 22 sind zu diesem nicht relativ verstellbar und weisen daher keine Spurkränze auf, um die erforderliche Querverschiebung der Vorrichtung nicht zu behindern.In the variant of a device for rail grinding shown in FIG. 7, functionally identical parts are provided with the same reference numerals as in FIGS. 1 to 6. This device 49 differs from the one already described in that the guide member 40 is not assigned to the rail 2 to be machined, but is designed as a double track roller 50 that can be rolled off on the opposite rail 2. This is again connected to the unit frame 8 via a transverse guide 24 and can be transversely adjusted relative to the latter. The transverse guide 24 is designed as a telescopically extendable or shortenable bar 51 and provided with a pressure element 41. The guide rollers 22 arranged on the unit frame 8 cannot be adjusted relatively to the latter and therefore have no wheel flanges in order not to hinder the required transverse displacement of the device.
