Abstract

The distance between support frame (6) or the pivot axis (21) extending in longitudinal track direction, and a support roller (10) opposite to the grinder unit (26), is reducible by a length compensation unit (14). The unit has a device (17), to generate a contact pressure force for the grinder on an inner flank of the head of the rail (3) to be ground. The contact pressure acts against a distance reduction. With max. distance between frame and support roller, the pivot axis of the frame is located at a distance, outside the rail, to a top outer rail head edge, in horizontal and in vertical direction.

Description

Die Erfindung betrifft eine Einrichtung zum Schleifen von Schienen eines Gleises, mit einem durch Stützrollen mit Drehachsen auf beiden Schienen abstützbaren Aggregatrahmen, dem ein Schleifaggregat mit einem im Bereich einer Schiene verstellbar auf einem Tragrahmen befestigten Schleiforgan zugeordnet ist, wobei der Tragrahmen mitsamt dem Schleiforgan durch einen Schwenkantrieb um eine Schwenkachse verschwenkbar am Aggregatrahmen gelagert ist, sowie mit einem vom Tragrahmen distanziert auf dem Aggregatrahmen befestigten Antriebsmotor.The invention relates to a device for grinding rails of a track, with an aggregate frame that can be supported by support rollers with axes of rotation on both rails, to which a grinding aggregate is assigned with a grinding member that is adjustable in the area of a rail and attached to a supporting frame, the supporting frame together with the grinding member by a Swivel drive is mounted on the unit frame so as to be pivotable about a swivel axis, and with a drive motor fastened to the unit frame at a distance from the support frame.

Derartige Einrichtungen dienen zum profilgerechten Abschleifen insbesondere der Laufflächen und Fahrkanten von Eisenbahnschienen zur Beseitigung von Unebenheiten am Schienenkopf, die als Folge von Verschleiß oder auch nach Schweißarbeiten auftreten.Devices of this type are used for grinding in accordance with the profile, in particular of the running surfaces and running edges of railroad tracks, in order to eliminate unevenness on the rail head which occurs as a result of wear or after welding work.

In einem Inserat in der Zeitschrift "Progressive Railroading", April 1981, Seite 11, ist eine Einrichtung zum Schleifen von Schienen eines Gleises dargestellt, die einen auf Stützrollen gleisverfahrbaren Aggregatrahmen aufweist. Dieser ist im Bereich einer der Schienen mit einem Tragrahmen verbunden, an dem als Schleiforgan eine Schleifscheibe angeordnet und anhand einer als Schwenkantrieb dienenden Hebelvorrichtung im Winkel zur Schienenlängsrichtung verstellbar ausgebildet ist. Der Motor bzw. das Antriebsaggregat für das Schleiforgan befindet sich auf der von diesem abgewandten Seite des Aggregatrahmens und ist mittels einer flexiblen Welle mit dem Schleiforgan verbunden. Mit dieser Einrichtung sind lediglich die Laufflächen der Schienen abschleifbar.In an advertisement in the magazine "Progressive Railroading", April 1981, page 11, a device for grinding rails of a track is shown, which has a unit frame that can be moved on support rollers. This is connected in the area of one of the rails to a support frame, on which a grinding wheel is arranged as a grinding element and is adjustable in angle to the longitudinal direction of the rail by means of a lever device serving as a pivot drive. The motor or the drive unit for the grinding element is located on the side of the unit frame facing away from it and is connected to the grinding element by means of a flexible shaft. With this device, only the running surfaces of the rails can be ground.

In der EP 0 110 246 B1 wird eine Einrichtung mit einem über Stützrollen auf den Schienen verfahrbaren Aggregatrahmen beschrieben, an dem im Bereich einer der Schienen ein Tragrahmen angeordnet ist, der um eine in Gleislängsrichtung ausgerichtete Schwenkachse mittels eines auslegerartig am Aggregatrahmen angelenkten Spindelantriebes kippbar ausgebildet ist.EP 0 110 246 B1 describes a device with a unit frame that can be moved on the rails via support rollers, on which a support frame is arranged in the area of one of the rails, and is designed to be tiltable about a pivot axis aligned in the longitudinal direction of the track by means of a spindle drive articulated on the unit frame in the manner of a cantilever .

Ein mitsamt seinem Motor am Tragrahmen befestigtes Bandschleifaggregat ist mit einer höhenverstellbaren Anpreßrolle ausgestattet und ist zum Tragrahmen zusätzlich um eine vertikale Achse verschwenkbar.A belt sanding unit with its motor attached to the support frame is equipped with a height-adjustable pressure roller and can also be pivoted about a vertical axis to the support frame.

Weiters sind gemäß einem Inserat in der Zeitschrift "Railway Track and Structures", April 1993, Seite 2, Einrichtungen zum Schleifen von Schienen bekannt, bei denen der Tragrahmen auf einem Aggregatrahmen über in Gleisquerrichtung verlaufende Führungen querverschiebbar montiert ist. Das Schleifaggregat ist mit dem Tragrahmen um eine parallel zur Schiene verlaufende Schwenkachse verschwenkbar verbunden, wobei der Vorschub des Schleiforganes senkrecht zur Schiene nach jeder Verschwenkung und Querverschiebung neu eingestellt wird.Furthermore, according to an advertisement in the magazine "Railway Track and Structures", April 1993, page 2, devices for grinding rails are known, in which the supporting frame is mounted on a unit frame by means of guides that run in the transverse direction of the track so that they can be moved. The grinding unit is connected to the support frame so as to be pivotable about a pivot axis running parallel to the rail, the feed of the grinding element perpendicular to the rail being readjusted after each pivoting and transverse displacement.

Andere bekannte Schienenschleifeinrichtungen sind zum Abrollen auf nur einer Schiene des Gleises ausgebildet und weisen einen ein Schleifaggregat samt Motor lagernden Tragrahmen auf, der über Stützrollen direkt auf der Schiene aufliegt und von einer Bedienungsperson während des Einsatzes in Balance gehalten werden muß. Zum Schleifen der seitlichen Schienenkopfkanten bzw. -flächen wird die Einrichtung in Gleisquerrichtung geneigt, wobei Halte- oder Führungsrollen ein Abrutschen des Schleifaggregates vom Schienenkopf verhindern.Other known rail grinders are designed for rolling on only one rail of the track and have a support unit which supports a grinding unit together with the motor and which rests directly on the rail via support rollers and must be kept in balance by an operator during use. To grind the lateral rail head edges or surfaces, the device is inclined in the transverse direction of the track, with holding or guide rollers preventing the grinding unit from slipping off the rail head.

Die Aufgabe der vorliegenden Erfindung besteht nun in der Schaffung einer gattungsgemäßen Einrichtung zum Schleifen von Schienen, mit der problemlos sowohl die Laufflächen als auch die innenliegenden Fahrkanten der Schienen mit einem Minimum an operativem Arbeitsaufwand bearbeitet werden können.The object of the present invention is to create a generic device for grinding rails, with which both the tread and the inner edges of the rails can be processed with a minimum of operational effort.

Diese Aufgabe wird mit einer Einrichtung der eingangs genannten Art dadurch gelöst, daß der Abstand zwischen Tragrahmen bzw. der in Gleislängsrichtung verlaufenden Schwenkachse und einer dem Schleifaggregat in Gleisquerrichtung gegenüberliegenden Stützrolle durch eine Längenkompensationseinheit reduzierbar ausgebildet ist, wobei diese Längenkompensationseinheit ein Druckorgan zur Erzeugung einer gegen die Abstandsreduktion wirksamen Anpreßkraft des Schleifaggregates an eine Schienenkopfinnenflanke der zu schleifenden Schiene aufweist.This object is achieved with a device of the type mentioned above in that the distance between the support frame or the pivoting axis running in the longitudinal direction of the track and a support roller opposite the grinding unit in the transverse direction of the track is designed to be reducible by a length compensation unit, this length compensation unit being a pressure element for generating an against the Distance reduction effective contact pressure of the grinding unit to an inner rail head flank of the rail to be ground.

Eine derart ausgebildete Einrichtung ermöglicht es nun erstmals, den zum Schleifen der Innenflanken einer Schiene erforderlichen Anpreßdruck des Schleiforganes weitgehend selbsttätig bzw. automatisch aufzubringen, wobei hierzu weder die Muskelkraft einer Bedienungsperson noch etwaige aufwendige Steuerungsmechanismen erforderlich sind. Im Rahmen der geoffenbarten Lösung kann auf konstruktiv einfachste Art erreicht werden, daß eine Querverschwenkung des Schleiforganes gleichzeitig auch eine Verkürzung des Aggregatrahmens in Gleisquerrichtung bewirkt, mit der in optimaler Weise ein Anspannen des Druckorganes zur Erzeugung der Anpreßkraft einhergeht. Neben einer Erhöhung der Arbeitsqualität wird dadurch auch eine wesentliche Vereinfachung des Bedienungsaufwandes und eine Entlastung des Arbeitspersonales erzielt.Such a device now makes it possible, for the first time, to apply the contact pressure of the grinding member, which is required for grinding the inner flanks of a rail, largely automatically or automatically, neither the muscle strength of an operator nor any complex control mechanisms being required. Within the framework of the disclosed solution, it can be achieved in a structurally simplest manner that a transverse pivoting of the grinding member also simultaneously shortens the unit frame in the transverse direction of the track, which optimally involves tightening the pressure member to generate the contact pressure. In addition to an increase in the quality of work, this also considerably simplifies the operating effort and relieves the workforce.

Die Anordnung gemäß Anspruch 2 gewährleistet die größtmögliche Querverstellung des Tragrahmens bzw. Abstandsreduktion des Schleiforganes zur gegenüberliegenden Schiene. Dies führt zu einem allmählichen Aufbau der erforderlichen Anpreßkraft im Rahmen der Verlagerung der Schwenkachse in Richtung zur Schienenkopfinnenflanke.The arrangement according to claim 2 ensures the greatest possible transverse adjustment of the support frame or reduction in distance of the grinding member to the opposite rail. This leads to a gradual build-up of the required contact pressure as part of the displacement of the swivel axis in the direction of the inside of the rail head.

Bei den Weiterbildungen gemäß den Ansprüchen 3, 4 und 5 werden in vorteilhafter Weise die Stützrollen gleichzeitig als - das Schleiforgan im korrekten Abstand auf dem Schienenkopf führende - Laufrollen verwendet, wobei dieser Abstand auch während der Verschwenkung des Tragrahmens um die in Gleislängsrichtung verlaufende Schwenkachse beibehalten wird. Dies hilft auch, um ein Kopieren bzw. Verstärken von kurzwelligen Schienenunebenheiten mit dem Schleiforgan zu verhindern.In the developments according to claims 3, 4 and 5, the support rollers are advantageously used at the same time as - guiding the grinding element at the correct distance on the rail head - rollers, this distance also being maintained during the pivoting of the support frame about the pivot axis running in the longitudinal direction of the track . This also helps to prevent copying or reinforcement of short-wave rail unevenness with the grinding element.

Die Merkmale der Ansprüche 6 bis 8 beschreiben eine bevorzugte Ausführungsform der Längenkompensationseinheit, die sich durch konstruktive Einfachheit und Zuverlässigkeit auszeichnet.The features of claims 6 to 8 describe a preferred embodiment of the length compensation unit, which is characterized by structural simplicity and reliability.

Die in Anspruch 9 bis 11 beschriebene Variante stellt sicher, daß es bei maximaler Querverschwenkung des Schleiforganes und Tragrahmens zum Schleifen der Schienenkopfinnenflanken zu keinem schwerkraftbedingten Abrutschen des Tragrahmens vom Schienenkopf kommen kann.The variant described in claims 9 to 11 ensures that, with maximum transverse pivoting of the grinding member and support frame for grinding the inside of the rail head flanks, there can be no gravity-induced sliding of the support frame from the rail head.

Schließlich bewirken die Ausbildungsmerkmale gemäß den Ansprüchen 12 bis 14 eine Erhöhung der Bedienerfreundlichkeit und eine wesentliche ergonomische Verbesserung der Schienenschleifeinrichtung.Finally, the training features according to claims 12 to 14 increase the user friendliness and a substantial ergonomic improvement of the rail grinding device.

Ein auf jedem Träger 15 zwischen Führungsrohr 16 und Platte 13 angeordnetes Druckorgan 17 in Form einer Schraubenfeder 18 spreizt die beiden Rahmenteile 7,8 in Gleisquerrichtung gegeneinander, wobei ein im Inneren der Führungsrohre 16 befindlicher Anschlag 48 (Fig. 3) diese Auseinanderbewegung begrenzt und ein Trennen der Rahmenteile 7,8 verhindert.The two frame parts 7, 8 are connected to one another via a length compensation unit 14, which allows the two frame parts 7, 8 to be adjusted relative to one another in the transverse direction of the track. The length compensation unit 14 is formed from two supports 15 which run in the transverse direction of the track and are fastened to the plate 13 and are each mounted telescopically displaceably in a guide tube 16 connected to the angle supports 9. A pressure element 17 in the form of a helical spring 18 arranged on each support 15 between the guide tube 16 and plate 13 spreads the two frame parts 7, 8 against one another in the transverse direction of the track, a stop 48 (FIG. 3) located inside the guide tubes 16 limiting and separating this movement apart Separation of the frame parts 7.8 prevented.

Der Tragrahmen 6 besteht im wesentlichen aus einem - in seiner Längsmitte einen von der Schiene 3 distanzierten, gekröpften Abschnitt 19 aufweisenden - Längsträger 20, der im Bereich seiner beiden Enden jeweils um eine in Gleislängsrichtung und parallel zur Gleisebene verlaufende Schwenkachse 21 rotierbar in einem Lagerblock 22 gelagert ist. Diese Lagerblöcke 22 sind wiederum jeweils endseitig an den Querträgern 12 des Aggregatrahmens 5 bzw. Rahmenteiles 8 befestigt. An den äußersten Enden des jeweils über den Querträger 12 vorragenden Längsträgers 20 des Tragrahmens 6 sind Stützrollen 23 montiert, die als - mit ihren Drehachsen 24 senkrecht zur Schwenkachse 21 verlaufende - spurkranzlose Laufrollen 25 ausgebildet sind und zur Abstützung des Tragrahmens 6 und Aggregatrahmens 5 auf der Schiene 3 dienen.The support frame 6 essentially consists of a longitudinal beam 20, which has a cranked section 19 distant from the rail 3 and has a cranked section 19 in its longitudinal center, which rotates in the bearing area 22 in the region of its two ends in each case about a pivot axis 21 running in the longitudinal direction of the track and parallel to the track plane is stored. These bearing blocks 22 are in turn fastened at each end to the cross beams 12 of the assembly frame 5 or frame part 8. Support rollers 23 are mounted on the outermost ends of the longitudinal member 20 of the support frame 6 projecting over the cross member 12, which are designed as trackless rollers 25 with their axes of rotation 24 perpendicular to the pivot axis 21 and for supporting the support frame 6 and assembly frame 5 on the Serve rail 3.

Innerhalb des gekröpften Abschnittes 19 des Tragrahmens 6 ist ein Schleifaggregat 26 angeordnet, das mit einem Schleiforgan 31 in Form einer rotierenden Topfscheibe 61 ausgestattet und anhand einer Parallelogrammanlenkung 27 mit einer aus Stützplatten 28 gebildeten Halterung 29 verbunden ist, die auf dem Tragrahmen 6 befestigt ist. Mittels eines Verstellantriebes 30, der in der Halterung 29 montiert und mit der Parallelogrammanlenkung 27 verbunden ist, kann das Schleifaggregat 26 bzw. das Schleiforgan 31 in seinem Abstand zur Schiene 3 zwecks Regulierung der Abtragtiefe verstellt werden. Im Arbeitseinsatz ist das, einen Hydromotor aufweisende Schleifaggregat 26 so positioniert, daß ein Berührungspunkt 47 des Schleiforganes 31 mit der Schiene 3 auf einer Verbindungslinie 49 liegt, die durch zwei jeweils durch einen Kontakt der Laufrollen 25 mit der zu bearbeitenden Schiene 3 gebildete Rollenaufstandspunkte 60 bestimmt ist, wobei die Rotationsachse 62 der Topfscheibe 61 senkrecht zur Verbindungslinie 49 bzw. einer Längsachse der Schiene 3 verläuft (Fig. 3).Arranged within the cranked section 19 of the support frame 6 is a grinding unit 26, which is equipped with a grinding member 31 in the form of a rotating cup wheel 61 and is connected by means of a parallelogram linkage 27 to a holder 29 formed from support plates 28, which is fastened to the support frame 6. By means of an adjustment drive 30, which is mounted in the holder 29 and is connected to the parallelogram linkage 27, the grinding unit 26 or the grinding member 31 can be adjusted in its distance from the rail 3 in order to regulate the removal depth. In work, the grinding unit 26, which has a hydraulic motor, is positioned such that a point of contact 47 of the grinding member 31 with the rail 3 lies on a connecting line 49, which is determined by two roller contact points 60, each formed by a contact of the rollers 25 with the rail 3 to be machined is, the axis of rotation 62 of the cup wheel 61 perpendicular to the connecting line 49 or a longitudinal axis of the rail 3 (Fig. 3).

Zur Verschwenkung des Tragrahmens 6 um die Schwenkachse 21 sind zwei hydraulische Schwenkantriebe 32 vorgesehen, die jeweils an den Querträgern 12 des Aggregatrahmens 5 und am Längsträger 20 angelenkt sind. Ein zur Energieversorgung der Schwenkantriebe 32 und des Schleifaggregates 26 dienender Antriebsmotor 33 mit einer Hydraulikpumpe 34 ist - vom Tragrahmen 6 distanziert - auf einer mit der Platte 13 des Aggregatrahmens 5 verbundenen Konsole 35 angeordnet, während sich Bedienungselemente 36 für besagte Schwenkantriebe 32 und ein Vorschubregler 37 für die Fernbedienung des Verstellantriebes 30 auf einem Bügel 38 des Aggregatrahmens 5 befinden. Die Energieversorgung erfolgt durch Hydraulikschläuche 63.For pivoting the support frame 6 about the pivot axis 21, two hydraulic swivel drives 32 are provided, which are each articulated on the cross members 12 of the assembly frame 5 and on the side member 20. A drive motor 33 with a hydraulic pump 34, which supplies power to the swivel drives 32 and the grinding unit 26, is arranged at a distance from the support frame 6 on a console 35 connected to the plate 13 of the assembly frame 5, while operating elements 36 for said swivel drives 32 and a feed regulator 37 for the remote control of the adjustment drive 30 on a bracket 38 of the assembly frame 5. Power is supplied by hydraulic hoses 63.

Wie nun insbesondere auch anhand der Fig. 4 zu erkennen ist, bewirkt eine Betätigung der (in Fig. 4 nicht gezeigten) Schwenkantriebe 32 eine Abrollbewegung des Schleiforganes 31 in Gleisquerrichtung um den Kopf 39 der Schiene 3 (siehe strichdoppelpunktierte Umrißlinien), wobei die - während der gesamten Schwenkbewegung auf der genannten Verbindungslinie 49 befindlichen - Laufrollen 25 das Schleiforgan 31 immer im gleichen Abstand zum Schienenkopf 39 halten. Um in der extremen Verschwenkstellung ein Abrutschen des Schleifaggregates 26 vom Schienenkopf 39 zu verhindern, ist am Tragrahmen 6 neben jeder Laufrolle 25 eine tellerradartige Führungsrolle 40 befestigt, die um eine etwa 45o im Winkel zur Drehachse 24 der Laufrolle 25 geneigte, senkrecht zur Schwenkachse 21 verlaufende Achse 41 rotierbar ist. Die Führungsrolle 40 ist mit einem zur Anlage an den Schienenkopf 39 bzw. eine äußere Schienenkopfkante 43 vorgesehenen Spurkranz 42 ausgestattet.As can now be seen in particular from FIG. 4, actuation of the swivel drives 32 (not shown in FIG. 4) causes the grinding member 31 to roll in the transverse direction of the track around the head 39 of the rail 3 (see dash-dotted outline lines), the - During the entire pivoting movement on the connecting line 49 mentioned - rollers 25 always keep the grinding member 31 at the same distance from the rail head 39. In order to prevent the grinding unit 26 from slipping off the rail head 39 in the extreme pivoting position, a supporting wheel-like guide roller 40 is fastened to the support frame 6 next to each roller 25, which can be rotated about an axis 41 which is inclined approximately 45 ° at an angle to the axis of rotation 24 of the roller 25 and runs perpendicular to the pivot axis 21. The guide roller 40 is equipped with a flange 42 provided for contact with the rail head 39 or an outer rail head edge 43.

Die Schwenkachse 21 des Tragrahmens 6 ist derart angeordnet, daß sie, bei maximal voneinander distanzierter Stellung der Rahmenteile 7,8 - wie in Fig. 1 bis 3 dargestellt - an der Außenseite der Schiene 3 positioniert und sowohl vertikal als auch horizontal von der oberen, äußeren Schienenkopfkante 44 distanziert ist. In dieser Stellung wird die horizontale Lauffläche 45 der Schiene bearbeitet. Wird nun der Tragrahmen 6 mitsamt dem Schleifaggregat 26 anhand der Schwenkantriebe 32 zur Bearbeitung der Schienenkopfinnenflanke 46 gekippt, kommt es zu einer zwangsläufigen Verlagerung der Schwenkachse 21 in Richtung zu den gegenüberliegenden Stützrollen 10 und somit zu einer Kompression des Druckorganes 17 der Längenkompensationseinheit 14, die dieser Abstandsreduktion zwischen Schwenkachse und Stützrollen entgegenwirkt und auf diese Art eine Anpreßkraft erzeugt, mit der das Schleiforgan 31 an den Schienenkopf 39 seitlich angepreßt wird.The pivot axis 21 of the support frame 6 is arranged in such a way that, when the frame parts 7, 8 are at a maximum distance from one another - as shown in FIGS. 1 to 3 - they are positioned on the outside of the rail 3 and both vertically and horizontally from the upper, outer rail head edge 44 is distanced. In this position, the horizontal running surface 45 of the rail is processed. If the support frame 6 together with the grinding unit 26 is tilted using the swivel drives 32 for machining the rail head inner flank 46, the swiveling axis 21 is inevitably displaced in the direction of the opposite support rollers 10 and thus the compression element 17 of the length compensation unit 14 is compressed Distance reduction between the pivot axis and support rollers counteracts and in this way generates a contact pressure with which the grinding member 31 is pressed laterally against the rail head 39.

Zur Beschreibung der in Fig. 5 und 6, 7 gezeigten weiteren Ausführungsbeispiele werden der Einfachheit halber für funktionsgleiche Teile die bereits beim obigen Beispiel verwendeten Bezugszeichen beibehalten.To describe the further exemplary embodiments shown in FIGS. 5 and 6, 7, the reference numerals already used in the above example are retained for the sake of simplicity for functionally identical parts.

Die in Fig. 5 dargestellte Einrichtung 50 zum Schienenschleifen weist einen aus nur einem Teil gebildeten Aggregatrahmen 5 auf, mit dem ein Tragrahmen 6 im Bereich der Schiene 3 um eine in Gleislängsrichtung verlaufende Schwenkachse 21 rotierbar verbunden ist. Der Aggregatrahmen ist auf der Schiene 2 über eine Doppelspurkranz-Stützrolle 10 und auf der Schiene 3 über zwei weitere, am Aggregatrahmen 5 befestigte und als Laufrollen 25 ausgebildete Stützrollen 23 in Gleislängsrichtung verfahrbar gelagert, wobei die Laufrollen 25 jeweils mit einem - zur Anlage an die Schienenkopfinnenflanke 46 der Schiene 3 vorgesehenen - Spurkranz 51 ausgestattet sind. Das dem Tragrahmen 6 gegenüberliegende Ende des Aggregatrahmens 5 ist als in Gleisquerrichtung verlaufender Träger 15 geformt, auf dem die Stützrolle 10 koaxial montiert und gleichzeitig in Längsrichtung des Trägers verschiebbar ist. Die solcherart gebildete Längenkompensationseinheit 14 weist eine als Druckorgan 17 dienende Schraubenfeder 18 auf, deren Anpreßkraft so gerichtet ist, daß alle drei Stützrollen zur Ausschaltung des Spurspieles an die Schienen 2,3 angedrückt werden.The device 50 shown in FIG. 5 for rail grinding has an aggregate frame 5 formed from only one part, to which a support frame 6 is rotatably connected in the region of the rail 3 about a pivot axis 21 running in the longitudinal direction of the track. The unit frame is mounted on the rail 2 via a double-track rim support roller 10 and on the rail 3 via two further support rollers 23 fastened to the unit frame 5 and designed as castors 25 and can be moved in the longitudinal direction of the track, the rollers 25 each having one - for contacting the Rail head inner flank 46 of the rail 3 provided - flange 51 are equipped. The opposite end of the support frame 6 of the unit frame 5 is as formed in the cross-track direction carrier 15 on which the support roller 10 is mounted coaxially and at the same time is displaceable in the longitudinal direction of the carrier. The length compensation unit 14 formed in this way has a helical spring 18 serving as a pressure element 17, the contact pressure of which is directed such that all three support rollers are pressed onto the rails 2, 3 to switch off the track play.

Der mit einem gekröpften Abschnitt 19 ausgebildete Tragrahmen 6 ist über eine Parallelogrammanlenkung 27 mit einem Schleifaggregat 26 verbunden, dessen Schleiforgan 31 senkrecht zum Schienenkopf 39 verstellbar ist. Zur Verschwenkung des Tragrahmens 6 samt Schleifaggregat 26 um die Schwenkachse 21 (siehe strichdoppelpunktiert gezeigte Stellung) dient ein Schwenkantrieb 32, der sowohl am Tragrahmen 6 als auch am Aggregatrahmen 5 angelenkt ist. Der Tragrahmen 6 ist außerdem mit einem Mitnehmerorgan 52 ausgestattet, das während der Querverschwenkung des Schleifaggregates 26 mit dem Schienenkopf 39 in Eingriff steht und eine Querverschiebung des Tragrahmens 6 und somit auch des Aggregatrahmens 5 in Richtung zur Schiene 2 bzw. zur Stützrolle 10 bewirkt. Dadurch wird die Schraubenfeder 18 zusammengedrückt und übt eine gegen die Schienenkopfinnenflanke 46 der Schiene 3 gerichtete Anpreßkraft des Schleiforganes 31 aus.The support frame 6, which is formed with a cranked section 19, is connected via a parallelogram linkage 27 to a grinding unit 26, the grinding member 31 of which is adjustable perpendicular to the rail head 39. A pivot drive 32, which is articulated both on the support frame 6 and on the assembly frame 5, is used to pivot the support frame 6 together with the grinding unit 26 about the pivot axis 21 (see the position shown in double-dashed lines). The support frame 6 is also equipped with a driver element 52 which engages with the rail head 39 during the transverse pivoting of the grinding unit 26 and causes a transverse displacement of the support frame 6 and thus also of the unit frame 5 in the direction of the rail 2 or the support roller 10. As a result, the helical spring 18 is compressed and exerts a contact pressure of the grinding element 31 directed against the inner rail head flank 46 of the rail 3.

Fig. 6 und 7 zeigen eine Schienenschleif-Einrichtung 53 mit einem Tragrahmen 6, der mit einem Aggregatrahmen 5 um eine parallel zur Schiene 3 verlaufende Schwenkachse 21 drehbar verbunden ist. Der Aggregatrahmen 5 besteht aus zwei in einem Gelenk 54 über Zwischenglieder 55 miteinander verbundenen Rahmenteilen 56,57, von denen der vom Tragrahmen 6 weiter distanzierte Rahmenteil 56 auf der Schiene 2 mittels Stützrollen 10 gelagert ist und zur Abstützung des Antriebsmotors 33 dient. Der Tragrahmen 6 ist ähnlich wie beim in Fig. 1 bis 4 beschriebenen Beispiel gekröpft ausgebildet und mit einem verstellbaren Schleifaggregat 26 ausgestattet sowie anhand von Laufrollen 25 auf der Schiene 3 abrollbar. Die den Laufrollen 25 zugeordneten Führungsrollen 40 sind hier jedoch - so wie die Laufrollen - walzenförmig ausgebildet und mit ihren Achsen 41 so angeordnet, daß sie zusammen mit den Laufrollen 25 den Schienenkopf 39 spitzwinkelig umschließen.6 and 7 show a rail grinding device 53 with a support frame 6 which is rotatably connected to an assembly frame 5 about a pivot axis 21 running parallel to the rail 3. The unit frame 5 consists of two frame parts 56, 57, which are connected to one another in a joint 54 via intermediate members 55, of which the frame part 56, which is further distanced from the supporting frame 6, is mounted on the rail 2 by means of support rollers 10 and serves to support the drive motor 33. The support frame 6 is cranked similarly to the example described in FIGS. 1 to 4 and is equipped with an adjustable grinding unit 26 and can be unrolled on the rail 3 by means of rollers 25. The guide rollers 40 assigned to the rollers 25 are here, however - like the rollers - roller-shaped and arranged with their axes 41 in such a way that, together with the rollers 25, they enclose the rail head 39 at an acute angle.

Wie in Fig. 7 zu erkennen, ist das Gelenk 54 als Längenkompensationseinheit 14 ausgebildet, die eine Querverstellung der Rahmenteile 56 und 57 des Aggregatrahmens 5 zueinander erlaubt, wenn der Tragrahmen 6 mit dem Schleifaggregat 26 anhand des Schwenkantriebes 32 um die Schwenkachse 21 gedreht wird. Die vier - die Längenkompensationseinheit 14 bildenden - Zwischenglieder 55 sind in Form eines in einer waagrechten Ebene liegenden Parallelogramms um senkrecht angeordnete Achsen 58 rotierbar gelenkig miteinander verbunden und über eine in Gleislängsrichtung verlaufende Feder 59 mit einer Vorspannung beaufschlagt. Infolge der Querverschiebung des Rahmenteiles 57 wird die Feder 59 auseinandergezogen und fungiert sodann als Druckorgan, das über die Zwischenglieder 55 bzw. den Rahmenteil 57 eine gegen die Schienenkopfinnenflanke 46 der Schiene 3 gerichtete Anpreßkraft des Schleifaggregates 26 ausübt.As can be seen in FIG. 7, the joint 54 is designed as a length compensation unit 14, which allows the frame parts 56 and 57 of the unit frame 5 to be adjusted transversely to one another when the support frame 6 with the grinding unit 26 is rotated about the pivot axis 21 by means of the swivel drive 32. The four intermediate members 55, which form the length compensation unit 14, are pivotally connected to one another in the form of a parallelogram lying in a horizontal plane so as to be rotatable about vertically arranged axes 58 and are preloaded via a spring 59 running in the longitudinal direction of the track. As a result of the transverse displacement of the frame part 57, the spring 59 is pulled apart and then acts as a pressure element which, via the intermediate members 55 or the frame part 57, exerts a contact pressure of the grinding unit 26 against the inner rail head flank 46 of the rail 3.

Im Rahmen der Erfindung sind sowohl Schleifaggregate mit rotierenden Schleifscheiben bzw. Schleifringen als auch Bandschleifaggregate gleichermaßen problemlos einsetzbar.Within the scope of the invention, grinding units with rotating grinding wheels or slip rings as well as belt grinding units can equally be used without any problems.
