Abstract

The invention relates to a miller for removing a road surfacing. When road surfacings are removed by means of relatively large millers, work remains to be done in the area of the manhole covers, gullies, road junctions or the like, which work cannot be carried out with the large miller. According to the invention, provision is made for arranging on the miller a supporting arm (30) having a milling head (39, 39a) arranged on its front end. The supporting arm (30) is adjustable transversely to the longitudinal axis (14) of the miller as well as along this axis so that, when the miller is stationary, the milling head (39, 39a) can be adjusted in a plane in the X-direction and Y-direction. By superimposing the regulating movements in the X-direction and Y-direction, any curve can be milled with the miller according to the invention so that the work remaining to be done can easily be carried out. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Fräsmaschine zum Abtragen einer aus Asphalt, Beton oder dgl. bestehenden Fahrbahndecke nach dem Oberbegriff des Anspruches 1.The invention relates to a milling machine for removing an asphalt, concrete or the like existing road surface according to the preamble of claim 1.

Zum Abtragen von Fahrbahndecken aus Asphalt, Beton oder dgl. sind große Fräsmaschinen bekannt, die mit rotierenden Fräswalzen arbeiten. Die Arbeitsbreite einer derartigen Straßenbaumaschine ist durch die Breite der Fräswalze bestimmt. Zwar können mit dieser Fräsmaschine in kurzer Zeit große Flächen abgetragen werden; Feinarbeiten wie Abfräsen des Fahrbahnbelages um einen Kanaldeckel oder dgl. sind mit einer derartigen Maschine jedoch nicht möglich. Daher müssen nach Ausführen der großflächigen Fräsarbeiten die verbleibenden Feinarbeiten um im Fahrbahnbelag vorgesehene Einbauten, am rechten und linken Fahrbahnrand, an Straßeneinmündungen und dgl. per Hand ausgeführt werden, was sehr zeitaufwendig ist. Benötigt eine Fräsmaschine zum großflächigen Abtragen des Fahrbahnbelags eines Straßenabschnittes einen Tag, so ist für die noch auszuführenden Feinarbeiten ein weiterer Zeitaufwand von mehreren Tagen anzusetzen.Large milling machines which work with rotating milling drums are known for removing road surfaces from asphalt, concrete or the like. The working width of such a road construction machine is determined by the width of the milling drum. Large areas can be removed in a short time with this milling machine; However, fine work such as milling the road surface around a manhole cover or the like is not possible with such a machine. Therefore, after the large-scale milling work has been carried out, the remaining fine work around the fixtures provided in the road surface, on the right and left edge of the road, at road junctions and the like must be carried out by hand, which is very time-consuming. If a milling machine needs one day to remove the pavement of a section of road over a large area, a further amount of time of several days must be taken for the fine work to be carried out.

Aus der AT-B 374 523 ist eine Fräsmaschine bekannt, deren Fahrgestell mit feststehenden Rädern auf Schienen läuft. Quer zur Fahrtrichtung des Fahrgestells ist ein Führungsrahmen mit einem quer zur Fahrtrichtung verfahrbaren Wagen angeordnet, der einen zum Boden gerichteten Fräskopf mit einer diamantbesetzten Scheibe und vertikaler Antriebswelle trägt. Die das Fahrgestell führenden Schienen müssen so ausgelegt werden, daß der abzutragende Fahrbahnbereich zwischen den Schienen liegt. Erst dann wird die Fräsmaschine auf das Gleis aufgesetzt und die Schneidscheibe in die Spurrinne abgesenkt, um zur Nivellierung einen Teil der Fahrbahndecke abzutragen. Bei dem Abheben des alten Fahrbahnbelags muß die gesamte Fräsmaschine in Längsrichtung der Schienen bewegt werden, wobei das Fahrgestell immer oberhalb des Arbeitsbereichs des Fräskopfes liegt, den Arbeitsbereich also weitgehend verdeckt. Der abzutragende Fahrbahnbereich ist zwangsläufig durch die vorher zu verlegenden Schienen begrenzt, was insbesondere dann zu Problemen führen kann, wenn der abzutragende Bereich erheblich größer ist als die Spurbreite des Fahrgestells. Die Schienen müssen dann auf der zu sanierenden Fahrbahndecke verlegt werden, was technisch und zeitlich sehr aufwendig ist. Die bekannte Fräsmaschine ist im wesentlichen zur Bearbeitung gerader Strecken ausgebildet; starke Krümmungen wie in den Randbereichen an Straßenkreuzungen und dgl. können mit vertretbarem Aufwand nicht bearbeitet werden.A milling machine is known from AT-B 374 523, the chassis of which runs on rails with fixed wheels. A guide frame with a carriage which can be moved transversely to the direction of travel is arranged transversely to the direction of travel of the chassis and carries a milling head directed towards the ground with a diamond-coated disk and vertical drive shaft. The rails guiding the chassis must be designed so that the roadway area to be removed lies between the rails. Only then is the milling machine placed on the track and the cutting disc lowered into the track groove in order to remove part of the pavement for leveling. When lifting off the old road surface, the entire milling machine has to be moved in the longitudinal direction of the rails, the chassis always being above the working area of the milling head, that is to say largely covering the working area. The roadway area to be removed is inevitably limited by the rails to be laid beforehand, which can lead to problems in particular if the area to be removed is considerably larger than the track width of the chassis. The rails must then be laid on the pavement to be renovated, which is technically and time-consuming. The known milling machine is essentially designed for machining straight sections; Strong curvatures such as in the edge areas at road crossings and the like cannot be machined with reasonable effort.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Fräsmaschine derart weiterzubilden, daß ohne großen technischen Aufwand und zeitlich aufwendiges Einrichten eine Fahrbahndecke oder dgl. längs einer beliebigen Kontur abfräsbar ist.The invention has for its object to develop a generic milling machine such that a road surface or the like. Can be milled along any contour without great technical effort and time-consuming setup.

Diese Aufgabe wird erfindungsgemäß nach den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved according to the characterizing features of claim 1.

Das Fahrgestell ist frei lenkbar, läuft also nicht auf Schienen. Der Fräskopf kann so durch Rangieren des Fahrgestells in eine für die Bearbeitung günstige Ausgangsposition gefahren werden. Der in seiner Länge einstellbare Teleskoparm, der die sich vertikal erstreckende Fräskopfträgerplatte mit dem Antriebsmotor und der Fräswelle trägt, ist in Fahrgestellängsrichtung ausgerichtet und ragt über das Fahrgestell hinaus. Somit ist eine Sichtkontrolle des Arbeitsbereiches des Fräskopfes möglich. Aufgrund der Ausbildung als Teleskoparm ist der Fräskopf in Längsrichtung des Fahrgestells verstellbar; durch den auf dem Führungsrahmen quer zur Fahrgestellängsachse verfahrbaren Wagen ist eine Bewegung des Tragarms quer zur Fahrgestelllängsachse möglich. Durch Zusammensetzung der Bewegungen in Fahrgestellängsrichtung und quer zur Fahrgestellängsrichtung läßt sich der Fräskopf in jede beliebige Position fahren, ohne das Fahrgestell selbst zu bewegen. Es sind somit ohne große technische Schwierigkeiten und Einrüstarbeiten Kreise ebenso fräsbar wie beliebige Konturen. Dabei ist wesentlich, daß der einmal auf seine Arbeitsebene abgesenkte Fräskopf trotz seiner Bewegung keine Höhenänderung erfährt, da das lenkbare Fahrgestell während der Bearbeitung der Kontur ortsfest verbleibt.The chassis is freely steerable, so it does not run on rails. The milling head can thus be moved into a starting position that is favorable for machining by maneuvering the chassis. The telescopic arm, which is adjustable in length and carries the vertically extending milling head carrier plate with the drive motor and the milling shaft, is aligned in the longitudinal direction of the chassis and protrudes beyond the chassis. This enables a visual inspection of the working area of the milling head. Due to the design as a telescopic arm, the milling head is adjustable in the longitudinal direction of the chassis; The carriage can be moved transversely to the longitudinal axis of the chassis by means of the carriage which can be moved transversely to the longitudinal axis of the chassis on the guide frame. By combining the movements in the chassis longitudinal direction and transversely to the chassis longitudinal direction, the milling head can be moved into any position without moving the chassis itself. Circles can be milled as well as any contours without great technical difficulties and scaffolding. It is essential that the milling head, once lowered to its working level, does not change its height despite its movement, since the steerable chassis remains stationary during machining of the contour.

Vorteilhaft ist das Fahrgestell der erfindungsgemäßen Fräsmaschine mit höhenverstellbaren Rädern ausgeführt, so daß die Fräseinheit höhenfest am Tragarm angeordnet werden kann. Es kann auch zweckmäßig sein, die Fräseinheit höhenverstellbar am Tragarm zu befestigen und ein Fahrgestell mit höhenfesten Rädern einzusetzen.The chassis of the milling machine according to the invention is advantageously designed with height-adjustable wheels, so that the milling unit can be arranged at a fixed height on the support arm. It may also be expedient to attach the milling unit to the support arm in a height-adjustable manner and to use a chassis with height-fixed wheels.

Die erfindungsgemäße Fräsmaschine besteht aus einem Fahrgestell 1, das über Räder 2 am Boden 3 abgestützt ist. Jedes Rad 2 ist an der im Schnitt vorzugsweise quadratischen Kolbenstange 4 einer Kolben/Zylindereinheit 5 befestigt. Die aus Vierkantrohr gefertigte Kolbenstange ist in Pfeilrichtung 6 höhenverstellbar, so daß die Lage des Fahrgestelles 1 zum Boden 3 beliebig einstellbar ist. Zumindest die beiden in Fahrtrichtung 7 vorne liegenden Räder 2 sind um vertikale Lenkachsen 8 drehbar angeordnet, wozu zwischen Kolbenstange 4 und Rad 2 ein Drehkranz 4a angeordnet ist. An dem Drehkranz 4a ist ein Rad 2 über einen Radträger 4b drehfest festgelegt. Die Drehbewegung des Rades 2 ist ebenfalls hydraulisch gesteuert. Vorzugsweise sind alle vier Räder des Fahrgestelles um vertikale Lenkachsen 8 drehbar. Auf diese Weise ist das Fahrgestell leicht zu manövrieren.The milling machine according to the invention consists of a chassis 1 which is supported on the floor 3 via wheels 2. Each wheel 2 is attached to the piston rod 4, which is preferably square in section, of a piston / cylinder unit 5. The piston rod made of square tube is in the direction of the arrow 6 adjustable in height so that the position of the chassis 1 to the floor 3 can be adjusted as desired. At least the two wheels 2 located at the front in the direction of travel 7 are arranged so as to be rotatable about vertical steering axes 8, for which purpose a rotating ring 4a is arranged between the piston rod 4 and the wheel 2. A wheel 2 is fixed on the turntable 4a in a rotationally fixed manner via a wheel carrier 4b. The rotation of the wheel 2 is also controlled hydraulically. All four wheels of the chassis are preferably rotatable about vertical steering axes 8. In this way, the chassis is easy to maneuver.

Auf dem Fahrgestell 1 ist ein Antriebsmotor 9 angeordnet, der in Fahrtrichtung 7 etwa vor den hinteren Rädern 2 liegt. Der Antriebsmotor 9 ist vorzugsweise ein Verbrennungsmotor, der mit einem Hydraulikmotor 10 gekoppelt ist. Der Hydraulikmotor 10 speist - über das Steuerpult 11 - die Kolben/Zylindereinheiten 5 der einzelnen Laufräder 2 sowie die an den einzelnen Laufrädern 2 angeordneten hydraulischen Radnabenmotoren (nicht dargestellt). Die Lenkbewegung um die Lenkachsen 8 ist mittels eines am Steuerpult 11 vorgesehenen Lenkrades 12 hydraulisch gesteuert. Das Steuerpult 11 ist vorzugsweise auf einem nachfolgend näher beschriebenen Tragarm 19 angeordnet, so daß der Steuersitz 12a den höchsten Punkt der Fräsmaschine bildet. Der Fahrer hat so einen für genaues Arbeiten erforderlichen freien Blick nach allen Seiten.A drive motor 9 is arranged on the chassis 1 and lies approximately in front of the rear wheels 2 in the direction of travel 7. The drive motor 9 is preferably an internal combustion engine which is coupled to a hydraulic motor 10. The hydraulic motor 10 feeds - via the control panel 11 - the piston / cylinder units 5 of the individual impellers 2 and the hydraulic wheel hub motors (not shown) arranged on the individual impellers 2. The steering movement about the steering axles 8 is hydraulically controlled by means of a steering wheel 12 provided on the control panel 11. The control panel 11 is preferably arranged on a support arm 19 described in more detail below, so that the control seat 12a forms the highest point of the milling machine. The driver thus has a clear view of all sides, which is necessary for precise work.

Am in Fahrtrichtung 7 vorderen Ende des Fahrgestelles 1 ist ein Führungsrahmen 13 befestigt, der quer zur Fahrgestelllängsachse 14 liegt. Die Querträger 15 des Führungsrahmens liegen dabei parallel zueinander in einem rechten Winkel zur Längsmittelachse 14 (Fig. 2). Die Querträger 15 haben U-förmigen Querschnitt und liegen mit ihren Öffnungen einander zugewandt. Sie sind an ihren Enden durch parallel zur Längsmittelachse 14 verlaufende Längsträger 16 starr miteinander verbunden und ferner auf dem Rahmen des Fahrgestelles 1 festgelegt, vorzugsweise festgeschweißt. Wie aus dem in Fig. 1 längs der Linie I-I in Fig. 2 teilgeschnitten dargestellten Rahmen 13 ersichtlich, ist in den U-förmigen Querträgern 15 ein Wagen 17 geführt. Dieser besteht im wesentlichen aus einem in der Ebene der Querträger 15 liegenden rechteckigen Rahmen, auf dessen Schmalseiten jeweils zwei Gleitrollen 18 angeordnet sind, die in dem U-Profil der Querträger gehalten sind. Auf dem Wagen 17 ist ein äußeres Vierkantrohr 19 befestigt und somit mit diesem quer zur Längsmittelachse 14 des Fahrgestelles 1 im Führungsrahmen 13 verfahrbar. Hierzu ist eine insbesondere hydraulische Stellvorrichtung 20 vorgesehen, die im Ausführungsbeispiel aus einer hydraulischen Kolben/Zylindereinheit besteht. Das vordere Ende der Kolbenstange 21 ist am Wagen 17 angelenkt, während das hintere Ende des Zylinders 22 am Längsträger 16 festgelegt ist.At the front end of the chassis 1 in the direction of travel 7, a guide frame 13 is fastened, which lies transverse to the longitudinal axis 14 of the chassis. The cross member 15 of the guide frame are parallel to each other at a right angle to the longitudinal central axis 14 (Fig. 2). The cross members 15 have a U-shape Cross-section and face each other with their openings. They are rigidly connected to one another at their ends by longitudinal beams 16 running parallel to the longitudinal central axis 14 and are also fixed, preferably welded, to the frame of the chassis 1. As can be seen from the frame 13 shown in FIG. 1 along the line II in FIG. 2, a carriage 17 is guided in the U-shaped cross members 15. This consists essentially of a rectangular frame lying in the plane of the cross member 15, on the narrow sides of which two sliding rollers 18 are arranged, which are held in the U-profile of the cross member. An outer square tube 19 is fastened on the carriage 17 and can thus be moved in the guide frame 13 transversely to the longitudinal central axis 14 of the chassis 1. For this purpose, a hydraulic actuating device 20, in particular, is provided, which in the exemplary embodiment consists of a hydraulic piston / cylinder unit. The front end of the piston rod 21 is articulated on the carriage 17, while the rear end of the cylinder 22 is fixed on the side member 16.

Im äußeren Vierkantrohr 19, dessen Mittelachse 24 parallel zur Längsmittelachse 14 liegt, ist ein inneres Vierkantrohr 25 axial verschieblich geführt. Zum axialen Ausfahren des inneren Vierkantrohrs 25 ist an einer Längsseite des äußeren Vierkantrohres 19 eine Stellvorrichtung 26 angeordnet, die im gezeigten Ausführungsbeispiel aus einer hydraulischen Kolben/Zylindereinheit besteht. Das hintere Ende des Zylinders 27 ist am hinteren Ende des Vierkantrohres 19 und das vordere Ende der Kolbenstange 28 am inneren Vierkantrohr 25 angelenkt. Mit der hydraulischen Kolben/Zylindereinheit 26 ist das innere Vierkantrohr 25 im Sinne des Doppelpfeiles 29 verfahrbar.In the outer square tube 19, the central axis 24 of which is parallel to the longitudinal central axis 14, an inner square tube 25 is axially displaceably guided. For the axial extension of the inner square tube 25, an adjusting device 26 is arranged on a long side of the outer square tube 19, which in the exemplary embodiment shown consists of a hydraulic piston / cylinder unit. The rear end of the cylinder 27 is articulated on the rear end of the square tube 19 and the front end of the piston rod 28 on the inner square tube 25. The inner square tube 25 can be moved in the sense of the double arrow 29 with the hydraulic piston / cylinder unit 26.

Wie aus der Draufsicht in Fig. 2 ersichtlich, steht der Führungsrahmen 13 seitlich über das Fahrgestell 1 über, so daß der Wagen bis seitlich neben das Fahrgestell verfahrbar ist. Die Länge des äußeren Vierkantrohres 19 ist ferner größer als die in Richtung der Längsmittelachse 14 gemessene Breite des Führungsrahmens 13. Vorzugsweise steht das Vierkantrohr 19 an seinem vorderen Ende weiter über als an seinem hinteren Ende.As can be seen from the top view in FIG. 2, the guide frame 13 projects laterally over the chassis 1, so that the carriage can be moved to the side next to the chassis. The length of the outer square tube 19 is also greater than the width of the guide frame 13 measured in the direction of the longitudinal central axis 14. The square tube 19 preferably projects further at its front end than at its rear end.

Die zueinander verfahrbaren Vierkantrohre 19, 25 bilden zusammen einen Tragarm 30, der in Fahrtrichtung 7 (Fig. 1) über das vordere Ende des Fahrgestelles 1 hinausragt. Am vorderen Ende des inneren Vierkantrohres ist eine vertikale Trägerplatte 31 befestigt, deren dem Boden zugewandtes unteres Ende 32 etwas unterhalb der Höhe des Fahrgestelles 1 liegt. Das obere Ende der Trägerplatte 31 steht über das äußere Vierkantrohr 19 vertikal über.The mutually movable square tubes 19, 25 together form a support arm 30 which projects in the direction of travel 7 (FIG. 1) beyond the front end of the chassis 1. At the front end of the inner square tube, a vertical support plate 31 is attached, the lower end 32 of which faces the floor is located slightly below the height of the chassis 1. The upper end of the support plate 31 projects vertically beyond the outer square tube 19.

Von der Trägerplatte erstrecken sich in Fahrtrichtung 7 nach vorne horizontale Halteflansche 33 bis 36, deren oberster Halteflansch 36 einen Antrieb 37, vorzugsweise einen hydraulischen Getriebemotor hält. Vom Antrieb 37 führt durch die anderen Halteflansche 33 bis 35 eine Fräswelle 38, die an ihrem unteren Ende einen Fräskopf 39 trägt. Die - vorzugsweise aus Vollmaterial gefertigte - Fräswelle 38 ist in den Halteflanschen 33 bis 35 in Fachlagern gehalten und abgestützt. Zwischen dem Halteflansch 34 und dem Halteflansch 35 ist eine Lager- und Schmiervorrichtung 40 für die Fräswelle 38 vorgesehen. Ferner ist vorteilhaft je ein von oben und von unten wirkendes Drucklager vorgesehen.Horizontal holding flanges 33 to 36 extend from the carrier plate in the direction of travel 7 to the front, the uppermost holding flange 36 holding a drive 37, preferably a hydraulic geared motor. From the drive 37 leads through the other holding flanges 33 to 35 a milling shaft 38 which carries a milling head 39 at its lower end. The - preferably made of solid material - milling shaft 38 is held and supported in the holding flanges 33 to 35 in specialist bearings. A bearing and lubrication device 40 for the milling shaft 38 is provided between the holding flange 34 and the holding flange 35. Furthermore, a pressure bearing acting from above and from below is advantageously provided.

Der Fräskopf 39 ist mittels eines Schnellverschlusses am unteren freien Ende der Fräswelle 38 drehfest gehalten und liegt unterhalb des unteren Endes 32 der Trägerplatte 31 auf der Höhe der Räder 2. Der Hydraulikmotor 37 ist über einen Hydraulikschlauch 41 mit dem Steuerpult 11 verbunden und wird in der Drehzahl vom Steuerpult aus geregelt. Der Fräskopf ist auf diese Weise am Tragarm 30 höhenfest angeordnet.The milling head 39 is held in a rotationally fixed manner by means of a quick-release fastener at the lower free end of the milling shaft 38 and lies below the lower end 32 of the carrier plate 31 at the level of the wheels 2. The hydraulic motor 37 is connected to the control panel 11 via a hydraulic hose 41 and is in the Speed controlled from the control panel. In this way, the milling head is arranged at a fixed height on the support arm 30.

Mit der erfindungsgemäßen Fräsmaschine kann entlang einer beliebigen Kontur die Fahrbahndecke abgefräst werden. Ist in der Fahrbahn zum Beispiel ein quadratischer Kanaldeckel 42 oder ein runder Kanaldeckel 43 vorgesehen, fährt die Fräsmaschine in Position und der Fräskopf 39 wird in seiner Höhe durch Höhenumstellung der Laufräder eingestellt. Über die hydraulischen Stellvorrichtungen 20, 26 wird der Fräskopf 39 an den Kanaldeckel 43 oder den Schachtdeckel 42 herangefahren. Durch Überlagerung der Stellbewegungen der Stellvorrichtung 20, 26 wird der Fräskopf 39 längs der kreisrunden Kontur des Kanaldeckels 43 geführt. Muß entlang der Kontur eines Schachtdeckels 42 gefräst werden, wird die eine oder die andere hydraulische Stellvorrichtung unabhängig von der anderen angesteuert. Die Fräswelle wird mit etwa 50 Umdrehungen pro Minute angetrieben.With the milling machine according to the invention, the pavement can be milled along any contour. If, for example, a square manhole cover 42 or a round manhole cover 43 is provided in the roadway, the milling machine moves into position and the height of the milling head 39 is adjusted by changing the height of the impellers. The milling head 39 is moved up to the manhole cover 43 or the manhole cover 42 via the hydraulic adjusting devices 20, 26. The milling head 39 is guided along the circular contour of the duct cover 43 by superimposing the adjusting movements of the adjusting device 20, 26. If it is necessary to mill along the contour of a manhole cover 42, one or the other hydraulic actuating device is controlled independently of the other. The milling shaft is driven at around 50 revolutions per minute.
