Description

Die Erfindung betrifft eine auf einer oder beiden Schiene(n) eines Gleises verfahrbare Schienenschleifmaschine mit einem in und gegebenenfalls zusätzlich quer zur Schienenlängsrichtung verschwenkbaren und mittels Laufrollen auf der oder den Schiene(n) geführten Rahmen, in welchem ein Schleifaggregat mit einem von einer Antriebsrolle angetriebenen umlaufenden Schleifband heb- und senkbar angeordnet ist.The invention relates to a rail grinding machine which can be moved on one or both rails of a track and has a frame which can be pivoted in and, if appropriate, additionally transversely to the longitudinal direction of the rail and is guided by means of rollers on the rail (s), in which a grinding unit is driven by a drive roller circumferential sanding belt can be raised and lowered.

Zum profilgerechten Abschleifen von Schweisswülsten, wie sie z.B. bei der aluminothermischen Schienenverbindungsschweissung entstehen, zum Abschleifen von überschüssigem Schweissgut bei der elektrischen Auftragsschweissung und beim Beseitigen wellen- oder rillenförmiger Unebenheiten auf den Fahrflächen der Schienen verwendet man Schienenschleifmaschinen, die auf einer oder beiden Schiene(n) eines Gleises insbesondere von Hand verfahrbar sind.For profile-correct grinding of welding beads, e.g. In the case of aluminothermic rail connection welding, to grind excess weld metal during electrical build-up welding and to remove wavy or groove-shaped irregularities on the running surfaces of the rails, rail grinding machines are used that can be moved on one or both rails of a track, in particular by hand.

Die aus dem Stand der Technik bekannten Schienenschleifmaschinen unterscheiden sich in ihrer Konstruktion im wesentlichen nur dadurch, dass man durch verschiedene konstruktive Ausgestaltungen das Problem des profilgemässen Abschleifens zu lösen versucht. Zu diesem Stand der Technik werden stellvertretend die deutschen Patentschriften Nrn. 1186094, 1274610, 2216692 und 2263958 sowie das Gebrauchsmuster Nr. 7710195 genannt.The construction of the rail grinding machines known from the state of the art essentially differs only in that one tries to solve the problem of grinding according to the profile by means of various structural designs. German Patent Nos. 1186094, 1274610, 2216692 and 2263958 and utility model No. 7710195 are cited as representative of this prior art.

Allen bekannten, auf den Schienen eines Gleises verfahrbaren Schienenschleifmaschinen ist gemeinsam, dass als Schleifwerkzeug eine gegebenenfalls topfförmig ausgebildete, kunstharz-oder keramikgebundene Schleifscheibe verwendet wird.It is common to all known rail grinding machines that can be moved on the rails of a track that an optionally pot-shaped, resin or ceramic-bonded grinding wheel is used as the grinding tool.

Diese Schleifscheiben haben eine Reihe von Nachteilen. So muss die Unterseite der Schleifscheibe in einem gewissen spitzen Winkel zur zu schleifenden Schienenoberfläche gehalten werden. Hierdurch entstehen, dem Radius der Schleifscheibe entsprechende Ausschleifungen. Die Schleifscheiben verbrauchen sich relativ schnell, wobei eine erhebliche Menge Abrieb entsteht, vor dem das Bedienungspersonal zu schützen ist. Ausserdem ist das Schleifen mit erheblichem Geräusch verbunden, so dass in Wohnbereichen verlegte Gleisanlagen häufig nur tagsüber geschliffen werden können.These grinding wheels have a number of disadvantages. So the underside of the grinding wheel must be held at a certain acute angle to the rail surface to be ground. This results in grinding corresponding to the radius of the grinding wheel. The grinding wheels wear out relatively quickly, creating a considerable amount of abrasion from which the operating personnel must be protected. In addition, grinding is associated with considerable noise, so that track systems installed in living areas can often only be ground during the day.

Ein weiterer Nachteil, der bei der Verwendung kunstharz- oder keramikgebundener Schleifscheiben zu beobachten ist, ist die starke Erhitzung der Schienenoberfläche beim Beschleifen. Hierdurch können spröde Härtungsgefüge entstehen, die bruchanfällig sind. Bei elektrisch aufgeschweissten Schienen hat man deshalb häufig nach dem Schleifen im Bereich des aufgeschweissten Schweissgutes Risse undAbbröcketungen festgestellt.Another disadvantage that can be observed when using synthetic resin or ceramic-bonded grinding wheels is the strong heating of the rail surface during grinding. This can result in brittle hardening structures that are prone to breakage. In the case of electrically welded rails, cracks and cut-offs were therefore frequently found in the area of the welded weld metal after grinding.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine verfahrbare Schienenschleifmaschine im Hinblick auf das Schleifwerkzeug so auszugestalten, dass die vorgenannten Nachteile nicht mehr, zumindest aber nicht mehr in dem entsprechend dem Stand der Technik beobachteten Umfang auftreten.The object of the present invention is to design a movable rail grinding machine with regard to the grinding tool in such a way that the aforementioned disadvantages no longer occur, but at least no longer to the extent observed in accordance with the prior art.

Diese Aufgabe wird bei der erfindungsgemässen Schleifmaschine dadurch gelöst, dass das Schleifband 1*9 über die Antriebsrolle 13 und eine einzige unter ihr angeordnete Anpressrolle 14 geführt ist, wobei die Antriebsrolle 13 und die Anpressrolle 14 gegeneinander verspannbar und beide gemeinsam in bezug zur Schienenlängsrichtung 35 bis zu einem Winkel von a < 30° verschwenkbar angeordnet sind.This object is achieved in the grinding machine according to the invention in that the grinding belt 1 * 9 is guided over the drive roller 13 and a single pressure roller 14 arranged underneath it, the drive roller 13 and the pressure roller 14 being clampable against one another and both together in relation to the longitudinal direction 35 to are arranged pivotable to an angle of a <30 °.

Es ist zwar aus dem Stand der Technik bekannt, Schleifbänder und insbesondere solche, die mit hoher Geschwindigkeit umlaufen, zum Beschleifen von Werkstücken zu verwenden. Diese Schleifbänder werden aber in stationären Anlagen eingesetzt und haben sich bei ortsbeweglichen Geräten bisher nur in Handschleifgeräten durchsetzen können, wie sie z.B. in der DE-PS Nr. 2841357 beschrieben sind. Bei Schienenschleifgeräten, die auf der Schiene verfahrbar sind, hat man rotierend schleifende Schleifbänder bisher noch nicht benutzt, obwohl zumindest in den vergangenen 30 Jahren der Bedarf an gleisverfahrbaren Schienenschleifmaschinen in erheblichem Umfang bestanden hat und die Nachteile der bekannten Vorrichtungen dem Fachmann geläufig waren. Zwar wurde in der CH Nr. 356483 auch schon ein Schleifband vorgeschlagen. Es übt jedoch seine Schleifwirkung lediglich durch die Bewegung der Maschine längs des Gleises aus, also nicht durch eigene Rotation relativ zur Maschine.It is known from the prior art to use grinding belts and in particular those which rotate at high speed for grinding workpieces. However, these sanding belts are used in stationary systems and have so far only been able to establish themselves with portable devices in hand-held sanders, such as those e.g. are described in DE-PS No. 2841357. In the case of rail grinders that can be moved on the rail, rotating grinding belts have not been used so far, although at least in the past 30 years there has been a considerable need for rail-mounted rail grinders and the disadvantages of the known devices were known to the person skilled in the art. A sanding belt has already been proposed in CH No. 356483. However, it only exerts its grinding action through the movement of the machine along the track, not through its own rotation relative to the machine.

Durch die Verspannung der Antriebsrolle und der Anpressrolle gegeneinander wird ein Flattern des Schleifbandes vermieden. Dabei hates sich als besonders günstig erwiesen, Antriebsrolle und Anpressrolle in bezug zur Schienenlängsrichtung verschwenkbar anzuordnen, wobei der mit der Schienenlängsrichtung gebildete Winkel bis zu 30° betragen kann. Durch diese Anordnung wird bei gleichzeitigem Bewegen der Schleifmaschine auf der Schiene ein besonders sauberer und glatter Schliff erzielt.The tensioning of the drive roller and the pressure roller against each other prevents the sanding belt from fluttering. It has proven to be particularly advantageous to arrange the drive roller and pressure roller so that they can pivot in relation to the longitudinal direction of the rail, the angle formed with the longitudinal direction of the rail being able to be up to 30 °. This arrangement results in a particularly clean and smooth finish while moving the grinding machine on the rail.

Die erfindungsgemässe Schleifmaschine gewährleistet die Bildung glatter und riefenfreier Oberflächen bei nur mässiger Hitzeentwicklung, die nicht zu einer Gefügeveränderung des Schienenwerkstoffes Anlass gibt. Der Abrieb ist gegenüber einer Schleifscheibe deutlich vermindert. Die erfindungsgemässe Schienenschleifmaschine arbeitet mit wesentlich geringerer Lärmbelästigung, so dass Schleifarbeiten mit dieser Maschine auch nachts in Wohngebieten durchgeführt werden können. Dabei übertrifft die Standzeit des Schleifbandes diejenige der Schleifscheibe, so dass auch die Rüstzeiten verringert sind.The grinding machine according to the invention ensures the formation of smooth and groove-free surfaces with only moderate heat development, which does not give rise to a change in the structure of the rail material. Abrasion is significantly reduced compared to a grinding wheel. The rail grinding machine according to the invention operates with significantly less noise pollution, so that grinding work with this machine can also be carried out at night in residential areas. The service life of the grinding belt exceeds that of the grinding wheel, so that the set-up times are reduced.

Eine bevorzugte Ausführungsform der erfindungsgemässen Schleifvorrichtung weist als besonderes Merkmal eine Anpressrolle 14 in Form einer Profilrolle auf, deren Profil dem Fahrflächenprofil der zu beschleifenden Schiene 36 angepasst ist. Dies ermöglicht ein exaktes, profilgerechtes Beschleifen des Schienenkopfes ohne Ausbildung eines Schienenkopfpolygons, wie dies bei Verwendung von Schleifkörpern, wie z.B. Schleifscheiben, nicht zu vermeiden ist. Bei Verwendung einer profilierten Anpressrolle muss der Winkel a = 0 sein.A preferred embodiment of the grinding device according to the invention has, as a special feature, a pressure roller 14 in the form of a profile roller, the profile of which is adapted to the running surface profile of the rail 36 to be ground. This enables the rail head to be grinded precisely, in accordance with the profile, without the formation of a rail head polygon, as is the case with Ver the use of grinding wheels, such as grinding wheels, cannot be avoided. When using a profiled pressure roller, the angle a = 0.

Die erfindungsgemässe Schienenschleifmaschine wird vorzugsweise von Hand auf den Schienen des Gleises verfahren. Man kann die Schleifmaschine jedoch auch mit einem eigenen Antrieb versehen oder mit einem angetriebenen Fahrzeug verbinden.The rail grinding machine according to the invention is preferably moved by hand on the rails of the track. However, the grinding machine can also be provided with its own drive or connected to a powered vehicle.

Zur Erzielung eines profilgerechten Schliffes wird das Schleifwerkzeug in einem Maschinenrahmen angeordnet, der in an sich bekannter Weise verschwenkbar angeordnet sein kann.To achieve a true-to-profile grinding, the grinding tool is arranged in a machine frame, which can be pivotably arranged in a manner known per se.

Eine besonders bevorzugte Ausführungsform der erfindungsgemässen Schleifmaschine ist dadurch gekennzeichnet, dass der Maschinenrahmen 1 mittels Achszapfen 2 verschwenkbar mit dem Fahrgestellrahmen, der aus Laufrollenträgern 3, 4 und längenverstellbaren Verbindungsstreben 5, 6 besteht und Laufrollen 7 aufweist, verbunden ist, wobei an den Maschinenrahmen 1 in seinem oberen Bereich ein Ausleger 8 in Form einer Spindel angelenkt ist, der sich auf den Laufrollenträger 4 abstützt, und wobei der Maschinenrahmen 1 einen durch eine Spindel 9 höhenverstellbaren Träger 10 mit Ausleger 15 aufweist, an welchem eine den Antriebsmotor 11 tragende Platte 12 angelenkt ist, wobei die Antriebsrolle 13 auf der Motorachse befestigt und die Anpressrolle 14 an dem der Schiene zugewendeten Ende des Auslegers 15 angeordnet ist, wobei der Abstand zwischen Antriebsrolle 13 und Anpressrolle 14 durch eine Spindel 16 veränderbar ist, und wobei das Schleifwerkzeug mit Antrieb und Anpressrolle 14 durch eine Spindel 17 über ein Gelenk 18, das mit dem Träger 10 fest verbunden ist, um die Achse 39 der Spindel 9 aus der Maschinenrahmenebene verschwenkbar ist, so dass das Schleifwerkzeug einen Winkel a <__ 30° mit der Schiene 36 einschliesst.A particularly preferred embodiment of the grinding machine according to the invention is characterized in that the machine frame 1 is pivotably connected by means of axle journals 2 to the chassis frame, which consists of roller carriers 3, 4 and length-adjustable connecting struts 5, 6 and has rollers 7, with the machine frame 1 in a boom 8 in the form of a spindle is articulated in its upper region, which is supported on the roller carrier 4, and the machine frame 1 has a carrier 10 with boom 15 which is height-adjustable by a spindle 9 and to which a plate 12 carrying the drive motor 11 is articulated , wherein the drive roller 13 is attached to the motor axis and the pressure roller 14 is arranged at the end of the boom 15 facing the rail, the distance between the drive roller 13 and pressure roller 14 being changeable by a spindle 16, and wherein the grinding tool with drive and pressure roller 14 through a spindle 17 via a joint 18 which is firmly connected to the carrier 10 and can be pivoted about the axis 39 of the spindle 9 from the machine frame plane, so that the grinding tool encloses an angle a <__ 30 ° with the rail 36.

Da die Schleifarbeiten häufig im befahrenen Gleis durchgeführt werden, besteht die Notwendigkeit, die Vorrichtung aus dem Gleis entfernen zu können. Dies wird bei einer bevorzugten Ausführungsform der erfindungsgemässen Schleifmaschine dadurch erreicht, dass der Maschinenrahmen 1 im Schienenbereich an der gleisabgewandten Seite zwei Ausleger mit jeweils einer Laufrolle 22 aufweist, die senkrecht zur Ebene des Maschinenrahmens 1 angeordnet sind. Die Maschine kann bei dieser Ausgestaltung aus dem Gleis gehoben und von diesem auf den Laufrollen 22 weggefahren werden.Since the grinding work is often carried out on the track used, it is necessary to be able to remove the device from the track. In a preferred embodiment of the grinding machine according to the invention, this is achieved in that the machine frame 1 in the rail area on the side facing away from the track has two brackets, each with a roller 22, which are arranged perpendicular to the plane of the machine frame 1. In this configuration, the machine can be lifted off the track and moved away from it on the rollers 22.

Zur besseren Handhabbarkeit der Maschine ist vorzugsweise am Maschinenrahmen 1 etwa rechtwinkelig zu diesem im oberen Bereich gleisabgewendet ein Führungsrahmen 21 mit Handgriffen 23 angeordnet.For better handling of the machine, a guide frame 21 with handles 23 is preferably arranged on the machine frame 1 at approximately a right angle to it in the upper region facing away from the track.

Eine weitere Ausführungsform hat das Kennzeichen, dass eine Stützstrebe 34 vom gleisabgewendeten Bereich des Führungsrahmens 21 zum schienennahen Bereich des Maschinenrahmens 1 angeordnet ist, mit der eine Lenkrolle 30 drehbar verbunden ist. Die Maschine ist dadurch nach dem Abkippen bequem von Hand ausserhalb des Gleises verfahrbar und manövrierbar.A further embodiment is characterized in that a support strut 34 is arranged from the area of the guide frame 21 facing away from the track to the area of the machine frame 1 close to the track, to which a steering roller 30 is rotatably connected. As a result, the machine can be easily moved and maneuvered outside of the track after tipping.

Die erfindungsgemässe Schleifmaschine wird anhand der Fig. 1, 2, 3 und 4 in einer bevorzugten Ausführungsform näher erläutert.The grinding machine according to the invention is explained in more detail in a preferred embodiment with reference to FIGS. 1, 2, 3 and 4.

Dabei zeigt Fig. 1 eine Aufsicht auf die erfindungsgemässe Vorrichtung mit schräggestelltem Schleifwerkzeug; Fig. 2 eine Seiten- und Schnittansicht der Vorrichtung quer zur Laufrichtung entsprechend der Schnittebene 11-11 in Fig. 1 und 3, wobei die Schleifwerkzeuge in nicht schräggestellter Position gezeigt sind; Fig. 3 zeigt eine Ansicht gemäss Pfeil 111 in Fig. 1 und 2 durch die Vorrichtung in Laufrichtung.1 shows a plan view of the device according to the invention with an inclined grinding tool; 2 shows a side and sectional view of the device transversely to the direction of travel corresponding to the cutting plane 11-11 in FIGS. 1 and 3, the grinding tools being shown in the non-inclined position; 3 shows a view according to arrow 111 in FIGS. 1 and 2 through the device in the running direction.

In Fig. 1 ist der Maschinenrahmen mit 1 bezeichnet. Der Fahrgestellrahmen 28 besteht aus den Laufrollenträgern 3 und 4 sowie den teleskopartigen Verbindungsstreben 5 und 6. Dabei sind die Streben 6 als Hülsen ausgebildet, in welchen die Streben 5 verschieblich angeordnet sind. Hierdurch kann der Fahrgestellrahmen 28 der Schienenspurweite angepasst werden. Hierzu sind Feststellschrauben 31 vorgesehen. Am Fahrgestellrahmen 28 befinden sich die Laufrollen 7. Der Maschinenrahmen 1 ist verschwenkbar im Fahrgestellrahmen angeordnet und kann um die Achszapfen 2 verschwenk werden.In Fig. 1 the machine frame is designated 1. The chassis frame 28 consists of the roller carriers 3 and 4 and the telescopic connecting struts 5 and 6. The struts 6 are designed as sleeves in which the struts 5 are arranged displaceably. As a result, the chassis frame 28 can be adapted to the track gauge. Locking screws 31 are provided for this purpose. The running wheels 7 are located on the chassis frame 28. The machine frame 1 is pivotably arranged in the chassis frame and can be pivoted about the journal 2.

Am Maschinenrahmen 1 ist im oberen Bereich ein Ausleger 8 angelenkt, der sich auf den Laufrollenträger 4 über Gelenk 32 abstützt. Durch Bewegen des Handrades 29 der Spindelhülse 33 des Auslegers 8 wird die wirksame Länge des Auslegers 8 verkürzt oder vergrössert, wodurch sich der Winkel des Maschinenrahmens 1 zur Senkrechten in gewünschter Weise entsprechend dem zu beschleifenden Schienenkopfprofil einstellen lässt.On the machine frame 1, a boom 8 is articulated in the upper region, which is supported on the roller carrier 4 via the joint 32. By moving the handwheel 29 of the spindle sleeve 33 of the boom 8, the effective length of the boom 8 is shortened or increased, whereby the angle of the machine frame 1 to the vertical can be adjusted in a desired manner in accordance with the rail head profile to be ground.

Am Motor 11 ist auf dessen Welle 26 die Antriebsrolle 13 befestigt, die in Fig. 1 durch die Schleifbandabdeckung 20 verdeckt, aber gestrichelt zu erkennen ist. Der den Motor 11, die Antriebsrolle 13 und die Anpressrolle 14 tragende Rahmen 10 kann durch Betätigung des Spindeltriebes 17, 40 über das Gelenk 18 um die Achse 39 der Spindel 9 verschwenkt werden. Hierdurch gelingt es, den gewünschten Winkel a, den die Anpressrolle 14 zur Laufrichtung 35 der Schiene 36 einhalten soll, einzustellen. Der Rahmen 34 für den Motor 11 und die Anpressrolle 14 lassen sich mittels Handrad 27 und Spindel 9 senkrecht auf und ab bewegen. Über die Spindel 16 wird die Bandspannung des Schleifbandes 20 eingestellt. Im oberen Bereich des Maschinenrahmens 1 befindet sich ein Führungsrahmen 21 mit Handgriffen 23 zur Führung der Schleifmaschine auf den Schienen 36 und zum Abkippen der Schleifmaschine aus dem Gleis auf die Laufrollen 22.On the motor 11, the drive roller 13 is fastened to the shaft 26 thereof, which is covered by the grinding belt cover 20 in FIG. 1, but can be seen in broken lines. The frame 10 carrying the motor 11, the drive roller 13 and the pressure roller 14 can be pivoted about the axis 39 of the spindle 9 by actuating the spindle drive 17, 40 via the joint 18. This makes it possible to set the desired angle a, which the pressure roller 14 is to maintain in relation to the running direction 35 of the rail 36. The frame 34 for the motor 11 and the pressure roller 14 can be moved vertically up and down by means of the handwheel 27 and spindle 9. The belt tension of the grinding belt 20 is set via the spindle 16. In the upper area of the machine frame 1 there is a guide frame 21 with handles 23 for guiding the grinding machine on the rails 36 and for tipping the grinding machine out of the track onto the rollers 22.

In Fig. 2 sind die Laufrollenträger wiederum mit 3 bezeichnet. Diese tragen eine Mehrzahl Rollen 7. An den Laufrollenträgern 3 befinden sich Achszapfen 2, um welche der Maschinenrahmen 1 schwenkbar gelagert ist. Die längenverstellbaren Verbindungsstreben sind jeweils mit 5 und 6 bezeichnet. Das Schleifband 19 wird vom Motor 11 und dem an dessen Achse angeordneten Antriebsrad 13 bewegt und um die Anpressrolle 14 geführt. Um das Schleifband 19 ist ein Abdeckblech 20 zum Schutz des Bedienungspersonals angebracht. Der Motor 11 ist auf einer Motorplatte 1-2 befestigt. Durch Betätigung des Handrades 37 und damit der Spindel 16 kann der Winkel zwischen Motorplatte 12 und Ausleger 15, der Bestandteil des Trägers 10 ist, verstellt und damit der Achsabstand zwischen Antriebsrolle und Anpressrolle verändert werden. Bei Vergrösserungen des Achsabstandes wird die Bandspannung erhöht. Der Rahmen 10, mit welchem der Ausleger 15 fest verbunden ist und damit über die Motortragplatte 12 der Motor 11, ist mittels der Spindel 9 heb- und senkbar, wobei durch die gezeigte Anordnung beim Heben und Senken eine Änderung der Bandspannung vermieden wird. Mittels Handrad 38 und Spindel 17 wird das Schleifwerkzeug 19 mit Antriebs- und Anpressrolle 13/14 um die Längsachse 39 der Spindel 9 bzw. Lager 43 verschwenkt. Hierzu ist z.B. die Spindelhülse 40 an ein Drehzapfenlager 41 drehbar angeordnet. Das verlängerte Ende der Spindel 17 wirkt auf das Gelenk 18.In Fig. 2, the roller carriers are again designated 3. These carry a plurality of rollers 7. On the roller carriers 3 there are axle journals 2, around which the machine frame 1 is pivotably mounted. The length-adjustable connecting struts are labeled 5 and 6, respectively. The grinding belt 19 is moved by the motor 11 and the drive wheel 13 arranged on its axis and guided around the pressure roller 14. A cover plate 20 is attached around the grinding belt 19 to protect the operating personnel. The motor 11 is mounted on a motor plate 1-2. By actuating the handwheel 37 and thus the spindle 16, the angle between the motor plate 12 and the boom 15, which is part of the carrier 10, can be adjusted and thus the center distance between the drive roller and the pressure roller can be changed. The belt tension is increased when the center distance increases. The frame 10, with which the boom 15 is fixedly connected, and thus the motor 11 via the motor support plate 12, can be raised and lowered by means of the spindle 9, with a change in the belt tension being avoided by the arrangement shown when lifting and lowering. Using handwheel 38 and spindle 17, grinding tool 19 with drive and pressure roller 13/14 is pivoted about longitudinal axis 39 of spindle 9 or bearing 43. For this purpose, for example, the spindle sleeve 40 is rotatably arranged on a pivot bearing 41. The elongated end of the spindle 17 acts on the joint 18.

Der Ausleger zum Verschwenken des Maschinenrahmens aus der senkrechten Ebene ist mit 8 bezeichnet.The boom for pivoting the machine frame from the vertical plane is designated 8.

Am Maschinenrahmen 1 befinden sich die elektrischen Anschlüsse 25 und die Regelvorrichtung 24 zum Regeln der Geschwindigkeit des Antriebsmotors.The electrical connections 25 and the regulating device 24 for regulating the speed of the drive motor are located on the machine frame 1.

In Fig. 3 ist die in den Fig. 1 und 2 gezeigte Vorrichtung in Fahrtrichtung, also Schienenlängsrichtung, gezeigt. Die Verbindungsstreben 5/6 verbinden den Laufrollenträger 4 mit dem Laufrollenträger 3. Die Laufrollen sind mit 7 bezeichnet. Der Ausleger 8, mit dem der Maschinenrahmen 1 um Achszapfen 2 verschwenkt werden kann, ist im oberen Bereich des Maschinenrahmens 1 bei 42 angelenkt und mit dem Laufrollenträger 4 beweglich verbunden. Der Motor ist mit 11 und die auf der Motorwelle 26 angeordnete Antriebsrolle mit 13 bezeichnet. Das Schleifband 19 ist um die Antriebsrolle 13 und die Anpressrolle 14 geführt. Der Führungsrahmen ist mit 21 bezeichnet.3 shows the device shown in FIGS. 1 and 2 in the direction of travel, that is to say the longitudinal direction of the rail. The connecting struts 5/6 connect the roller carrier 4 with the roller carrier 3. The rollers are designated by 7. The boom 8, with which the machine frame 1 can be pivoted about pivot 2, is articulated in the upper region of the machine frame 1 at 42 and movably connected to the roller carrier 4. The motor is designated 11 and the drive roller arranged on the motor shaft 26 is designated 13. The grinding belt 19 is guided around the drive roller 13 and the pressure roller 14. The guide frame is designated 21.

Fig. 4 zeigt eine als Profil rolle ausgebildete Anpressrolle 14, um die das Schleifband 19 geführt ist. Dabei entspricht das Profil 14'der Anpressrotte 14 negativ dem Profil 36' des Schienenkopfes im Bereich seiner Lauffläche und gestattet ein profilgerechtes Schleifen. Es werden somit auch die Rundungen 36" des Schienenkopfes 36 vom Schleifband 19 bearbeitet. Ein Bund 14" auf beiden Seiten der Anpressrolle 14 sorgt jeweils für eine sichere Führung des Schleifbandes 19. Die profilierte Anpressrolle 14 kann dabei entsprechend dem zu beschleifenden Schienenkopfprofil ausgewechselt werden.Fig. 4 shows a roll formed as a profile pressure roller 14, around which the grinding belt 19 is guided. The profile 14 'of the pressure pad 14 corresponds negatively to the profile 36' of the rail head in the area of its running surface and allows grinding to match the profile. The curves 36 "of the rail head 36 are thus also machined by the grinding belt 19. A collar 14" on both sides of the pressure roller 14 ensures safe guidance of the grinding belt 19. The profiled pressure roller 14 can be replaced in accordance with the rail head profile to be ground.
