Description

Die Erfindung betrifft eine Rangiervorrichtung zur Montage einer auswechselbaren Fräseinrichtung mit einer vorgegebenen Arbeitsbreite unterhalb eines höhenverstellbaren Maschinenrahmens einer Straßenbaumaschine, wie Straßenfräsmaschine, Stabilisierer, oder Recycler, der von Rädern oder Kettenlaufwerken getragen wird.The invention relates to a shunting device for mounting a replaceable milling device with a predetermined working width below a height-adjustable machine frame of a road construction machine, such as road milling machine, stabilizer, or recycler, which is supported by wheels or crawler tracks.

Die bekannten Straßenfräsmaschinen finden zur Sanierung von Asphalt- oder Betonfahrbahnen Verwendung. Zum Abfräsen der Fahrbahnoberfläche verfügen die bekannten Straßenfräsmaschinen über eine Fräseinrichtung, die eine mit Fräsmeißeln bestückte Fräswalze aufweist. Die Fräseinrichtung der bekannten Straßenfräsmaschinen ist unterhalb des Maschinenrahmens zwischen den vorderen und hinteren Kettenlaufwerken angeordnet, die den Maschinenrahmen tragen.The known road milling machines are used for the rehabilitation of asphalt or concrete pavements. For milling the road surface, the known road milling machines have a milling device which has a milling drum equipped with milling cutters. The milling device of the known road milling machines is arranged below the machine frame between the front and rear crawler tracks which support the machine frame.

Es sind Straßenfräsmaschinen mit Fräseinrichtungen unterschiedlicher Arbeitsbreite bekannt. Wenn Großfräsen mit Fräseinrichtungen ausgestattet sind, deren Arbeitsbreite die zulässige Fahrzeugbreite überschreitet, ist für den Transport der Straßenfräsmaschine zum Einsatzort eine Sondergenehmigung notwendig. Um eine Sondergenehmigung zu umgehen, muss die Fräseinrichtung von der Großfräse demontiert und in Längsrichtung zur Straße, beispielsweise auf einem Tieflader, zum Einsatzort transportiert werden. Am Einsatzort ist dann die Montage der Fräseinrichtung an der Fräse erforderlich. Diese Möglichkeit wird in der Praxis nur selten genutzt, da die Montage bzw. Demontage der Fräseinrichtung aufgrund der hohen Anzahl an Montageschritten und des großen Gewichts der Fräseinrichtung arbeits- und zeitaufwendig ist. Auch ist am Einsatzort ein Kran erforderlich. Daher finden Fräseinrichtungen mit einer großen Arbeitsbreite in der Praxis nur eine geringe Akzeptanz.There are known road milling machines with milling devices of different working width. If large milling machines are equipped with milling devices whose working width exceeds the permissible vehicle width, a special permit is required for transporting the road milling machine to the place of use. In order to avoid a special permit, the milling device must be removed from the large milling machine and transported longitudinally to the road, for example on a low loader, to the place of use. On site then the installation of the milling device on the mill is required. This option is rarely used in practice, since the assembly and disassembly of the milling device is laborious and time-consuming due to the high number of assembly steps and the large weight of the milling device. Also, a crane is required on site. Therefore find milling devices with a large working width in practice only a low acceptance.

Aus der DE 28 42 173 ist eine Straßenfräsmaschine bekannt, die aus einem von einem herkömmlichen Sattelzug gehaltenen Sattelauflieger besteht, der eine Fräswalze trägt. In der DE 28 42 173 wird das Problem des Transports von Fräswalzen mit einer großen Arbeitsbreite auf öffentlichen Straßen diskutiert. Zur Lösung dieses Problems wird eine schwenkbare Lagerung der Fräswalze an dem Sattelauflieger vorgeschlagen. Für den Transport wird die Fräswalze derart verschwenkt, dass die Fräswalze in Fahrtrichtung des Sattelzugs angeordnet ist. Dadurch wird vermieden, dass die Fräswalze seitlich über den Sattelzug vorsteht. Dieser Stand der Technik geht aber von einer hydraulisch angetriebenen Fräswalze aus, die eine solche Vorgehensweise ermöglicht. Moderne Straßenfräsen, Stabilisierer und Recycler haben jedoch einen mechanischen Antrieb, der ein Verschwenken der Fräswalze nicht zulässt. Außerdem verlangt diese Lösung einen deutlich verlängerten Radstand, wodurch die Maschine an Wendigkeit verliert.From the DE 28 42 173 a road milling machine is known, which consists of a held by a conventional tractor semitrailer carrying a milling drum. In the DE 28 42 173 becomes the problem of transporting milling drums with a large one Working width discussed on public roads. To solve this problem, a pivotable mounting of the milling drum on the semitrailer is proposed. For transport, the milling drum is pivoted in such a way that the milling drum is arranged in the direction of travel of the semitrailer. This avoids that the milling drum protrudes laterally over the tractor. However, this prior art is based on a hydraulically driven milling drum, which allows such an approach. However, modern road milling, stabilizer and recycler have a mechanical drive that does not allow pivoting of the milling drum. In addition, this solution requires a significantly longer wheelbase, causing the machine loses maneuverability.

Die bekannte Transportvorrichrung für Flugzeugtriebwerke, die sich einsatzbedingt durch eine relativ große Bauhöhe auszeichnet, verfügt über einen gegenüber dem Boden in der Höhe verstellbaren Transportrahmen, an dem über Schwingen Räder befestigt sind. Der Transportrahmen besteht aus festen Längsprofilen, an denen eine Trageinrichtung für eine speziell zur Aufnahme eines Flugzeugtriebwerks ausgebildete Aufnahmeeinheit befestigt ist. Die Aufnahmeeinheit für das Flugzeugtriebwerk soll an der Trageinrichtung rollbar befestigt werden können. Eine Vorrichtung zum Positionieren und Transportieren von Flugzeugtriebwerken ist auch aus der DE 196 12 626 A1 bekannt.The GB 929 322 A describes a device which is intended exclusively for the transport of aircraft engines. The well-known Transportvorrichrung for aircraft engines, which is characterized by its use by a relatively large height, has a relative to the ground in height adjustable transport frame, are attached to the swinging wheels. The transport frame consists of fixed longitudinal profiles on which a support device for a specially designed for receiving an aircraft engine receiving unit is attached. The receiving unit for the aircraft engine should be able to be mounted on the support rollable. A device for positioning and transporting aircraft engines is also known from DE 196 12 626 A1 known.

The maneuvering device has a longitudinally extendable transport frame on which the wheels relative to the transport frame are adjustably mounted in height so that the transport frame can be moved from a position in which the transport frame is lowered in a raised position in which Transports is raised.

In der abgesenkten Position kann die Rangiervorrichtung mit der aufliegenden Fräseinrichtung unter den Maschinenrahmen der Straßenfräsmaschine gefahren werden. Nach dem Anheben der Rangiervorrichtung aus der abgesenkten Position in die angehobene Position befindet sich die Fräseinrichtung auf der Höhe, in der die Fräseinrichtung an der Straßenfräsmaschine montiert werden kann. Die einzelnen Schritte zum Montieren der Fräseinrichtung einer Straßenfräsmaschine sind dem Fachmann bekannt.In the lowered position, the shunting device with the resting milling device can be moved under the machine frame of the road milling machine. After lifting the shunting device from the lowered position to the raised position, the milling device is at the height at which the milling device can be mounted on the road milling machine. The individual steps for mounting the milling device of a road milling machine are known in the art.

Das Anheben bzw. Absenken der Rangiervorrichtung erlaubt auch das Aufnehmen und Absetzen der Fräseinrichtung auf einer Trageinrichtung, auf der die Fräseinrichtung am Einsatzort abgestellt bzw. aufgehangen werden kann.The raising or lowering of the maneuvering device also allows the receiving device to be picked up and set down on a carrying device on which the milling device can be parked or suspended at the place of use.

Die auf der Rangiervorrichtung aufliegende Fräseinrichtung kann zum Einsatzort mit einem Tieflader transportiert werden, auf dem die Rangiervorrichtung mit der Fräseinrichtung in Längsrichtung verladen wird. Da die Fräseinrichtung mit der Rangiervorrichtung auf den Tieflader hinauf gefahren bzw. von dem Tieflader herunter gefahren werden kann, ist der Einsatz eines Krans am Einsatzort nicht erforderlich.The milling device resting on the maneuvering device can be transported to the place of use by means of a low loader on which the maneuvering device with the milling device is loaded in the longitudinal direction. Since the milling device with the maneuvering device can be driven up onto the low loader or driven down from the low loader, it is not necessary to use a crane at the place of use.

In der abgesenkten Position zeichnet sich die Rangiervorrichtung durch eine relativ geringe Bauhöhe aus, was das Unterfahren der Straßenfräsmaschine erleichtert. Um den unterhalb des Maschinenrahmens der Straßenfräsenmaschine zur Verfügung stehenden Raum zu vergrößern, wird der Maschinenrahmen der Straßenfräsmaschine vorzugsweise angehoben, bevor die Rangiervorrichtung mit der Fräseinrichtung unter den Maschinenrahmen gefahren wird.In the lowered position, the shunting device is characterized by a relatively low height, which facilitates driving under the road milling machine. In order to increase the space available below the machine frame of the road milling machine, the machine frame of the road milling machine is preferably raised before the shunting device with the milling device is moved under the machine frame.

Neben der verhältnismäßig geringen Bauhöhe zeichnet sich die erfindungsgemäße Rangiervorrichtung auch dadurch aus, dass der Transportrahmen in Längsrichtung verlängerbar ist. Dadurch ist es möglich, die Rangiervorrichtung an die unterschiedlichen Arbeitsbreiten der verschiedenen Fräseinrichtungen anzupassen, so dass die Länge des Transportrahmens genau der Länge der Fräseinrichtung entspricht. Damit werden die Abmessungen der Rangiervorrichtung gering gehalten, wodurch sich die Rangiervorrichtung einfacher rangieren lässt. Insbesondere ergeben sich daraus engere Wendekreise.In addition to the relatively low height, the shunting device according to the invention is also characterized by the fact that the transport frame can be extended in the longitudinal direction. This makes it possible to adapt the shunting device to the different working widths of the different milling devices, so that the length of the transport frame corresponds exactly to the length of the milling device. Thus, the dimensions of the maneuvering device are kept low, which makes the maneuvering easier to maneuver. In particular, this results in tighter turning circles.

Bei einer bevorzugten Ausführungsform der erfindungsgemäßen Rangiervorrichtung sind die Räder an parallel zur Fahrtrichtung ausgerichteten Schwingen befestigt, die um eine quer zur Fahrtrichtung verlaufende im Wesentlichen waagerecht angeordneten Rotationsachse schwenkbar an den Längsseiten des Transportrahmens gelagert sind. Vorzugsweise sind an beiden Seiten des Transportrahmens jeweils eine in Längsrichtung des Transportrahmens vordere und hintere Schwinge schwenkbar befestigt. Diese Radaufhängung ermöglicht eine verhältnismäßig geringe Bauhöhe der Rangiervorrichtung bei einem verhältnismäßig großen Hub zwischen der abgesenkten und angehobenen Position. Auch erleichtern die Schwingen den Transport der Rangiervorrichtung auf einem Tieflader, da sich die Rangiervorrichtung, die auf der Ladefläche des Tiefladers zusammen mit der aufliegenden Fräseinrichtung verzurrt wird, an den Schwingen abstützen kann. Daraus ergibt sich eine verbesserte Stabilität beim Transport. Die Schwingen selbst können beispielsweise auf Holzprofilen oder dergleichen aufliegen, die sich aufgrund der Höhenverstellung leicht unter die Schwingen schieben lassen.In a preferred embodiment of the shunting device according to the invention, the wheels are attached to aligned parallel to the direction of swing, which arranged around a transverse to the direction of travel extending substantially horizontally Rotary axis are pivotally mounted on the longitudinal sides of the transport frame. Preferably, in each case one in the longitudinal direction of the transport frame front and rear rocker are pivotally mounted on both sides of the transport frame. This suspension allows a relatively low height of the shunting device with a relatively large stroke between the lowered and raised position. Also, the wings facilitate the transport of the shunting device on a low loader, since the shunting device, which is lashed to the cargo bed of the flatbed together with the overlying Fräseinrichtung can be supported on the wings. This results in improved stability during transport. The wings themselves, for example, rest on wood profiles or the like, which can be easily pushed under the wings due to the height adjustment.

Zum Verschwenken der Schwingen sind vorzugsweise Kolben-Zylinder-Anordnungen vorgesehen, die einerseits gelenkig mit dem Transportrahmen und andererseits gelenkig mit den Schwingen verbunden sind. Durch Ausfahren und Einfahren der Kolben-Zylinder-Anordnungen wird der Transportrahmen in der Höhe verstellt. Die Kolben-Zylinder-Anordnungen sind vorzugsweise an dem Transportrahmen derart befestigt, dass sie sich in der Höhe im Wesentlichen nicht über die Aufnahmeeinheit der Fräseinrichtung hinaus erstrecken. Dadurch wird die Bauhöhe der Rangiervorrichtung gering gehalten.For pivoting the rocker piston-cylinder arrangements are preferably provided which are connected on the one hand articulated to the transport frame and on the other hand articulated to the wings. By extending and retracting the piston-cylinder assemblies, the transport frame is adjusted in height. The piston-cylinder assemblies are preferably mounted to the transport frame so that they do not extend in height substantially beyond the receiving unit of the milling device. As a result, the height of the maneuvering device is kept low.

Vorzugsweise sind an beiden Seiten des Transportrahmens jeweils eine in Längsrichtung des Transportrahmens vordere und hintere Schwinge schwenkbar befestigt. Die vorderen Schwingen und/oder die hinteren Schwingen können auch über Querprofile miteinander verbunden sein.Preferably, in each case one in the longitudinal direction of the transport frame front and rear rocker are pivotally mounted on both sides of the transport frame. The front wings and / or the rear wings can also be interconnected via transverse profiles.

Eine weitere bevorzugte Ausführungsform sieht vor, dass der Maschinenrahmen zwei äußere Grundrahmen und einen Innenrahmen aufweist. Die beiden äußeren Grundrahmen und der Innenrahmen sind zur Längenverstellung des Transportrahmens in Längsrichtung des Transportrahmens gegeneinander verschiebbar geführt. Dadurch wird ein relativ einfacher Aufbau bei einer verhältnismäßig großen Stabilität erzielt. Der Maschinenrahmen kann aber auch nur aus zwei Rahmenteilen bestehen, die gegeneinander längsverschiebbar geführt sind.A further preferred embodiment provides that the machine frame has two outer base frames and an inner frame. The two outer base frame and the inner frame are guided for length adjustment of the transport frame in the longitudinal direction of the transport frame against each other. As a result, a relatively simple structure is achieved with a relatively high stability. The machine frame can also consist of only two frame parts, which are guided longitudinally displaceable against each other.

In einer besonders bevorzugten Ausführungsform weisen die äußeren Grundrahmen Hohlprofile und der Innenrahmen Träger auf, wobei die Träger des Innenrahmens längsverschiebbar in den Hohlprofilen der Grundrahmen geführt sind. Es ist aber auch möglich, dass die Grundrahmen Träger und der Innenrahmen Hohlprofile zur längsverschiebbaren Aufnahme der Träger der Grundrahmen aufweist.In a particularly preferred embodiment, the outer base frame hollow profiles and the inner frame carrier, wherein the support of the inner frame are guided longitudinally displaceable in the hollow sections of the base frame. But it is also possible that the base frame carrier and the inner frame has hollow profiles for longitudinally displaceable receiving the carrier of the base frame.

Die Aufnahmeeinheit weist vorzugsweise eine in Längsrichtung des Transportrahmens vordere Aufnahme für den vorderen Bereich der Fräseinrichtung und eine in Längsrichtung des Transportrahmens hintere Aufnahme für den hinteren Bereich der Fräseinrichtung auf. Folglich liegt die Fräseinrichtung nur am vorderen und hinteren Ende der Rangiervorrichtung auf. An der Fräseinrichtung sind vorzugsweise entsprechende Aufnahmen vorgesehen, mit denen die Fräseinrichtung sicher auf der Rangiervorrichtung verladen werden kann.The receiving unit preferably has a front receptacle for the front area of the milling device in the longitudinal direction of the transport frame and a receptacle for the rear area of the milling device which is at the rear in the longitudinal direction of the transport frame. Consequently, the milling device rests only on the front and rear ends of the shunting device. Appropriate receptacles are preferably provided on the milling device with which the milling device can be safely loaded onto the maneuvering device.

An dem Transportrahmen sind die Räder vorzugsweise derart befestigt, dass sich die Räder in der Höhe nur unwesentlich über die Aufnahmeeinheit für die Fräseinrichtung hinaus erstrecken, wenn sich der Transportrahmen in der abgesenkten Position befindet. Dadurch wird die Bauhöhe der Rangiervorrichtung gering gehalten.On the transport frame, the wheels are preferably mounted such that the wheels extend in height only slightly beyond the receiving unit for the milling device, when the transport frame is in the lowered position. As a result, the height of the maneuvering device is kept low.

Bei einer bevorzugten Ausführungsform ist die viel Platz beanspruchende Antriebseinheit, die mehrere Aggregate, beispielsweise Antriebsmotor, Hydraulikpumpen etc. umfassen kann, an einem Ende des Transportrahmens angeordnet. Dadurch wird erreicht, dass die Rangiervorrichtung im Bereich der Aufnahmeeinheit die geringe Bauhöhe beibehält, um unter den Maschinenrahmen der Straßenfräsmaschine gefahren werden zu können. Die Antriebseinheit befindet sich dann vor bzw. hinter der auf der Aufnahmeeinheit aufliegenden Fräseinrichtung an dem einen oder anderen Seite des Maschinenrahmens der Fräsmaschine.In a preferred embodiment, the much space consuming drive unit, which may include multiple units, such as drive motor, hydraulic pumps, etc., arranged at one end of the transport frame. This ensures that the maneuvering device in the area of the receiving unit retains the low height to be driven under the machine frame of the road milling machine can. The drive unit is then located in front of and behind the milling device resting on the receiving unit on one or the other side of the machine frame of the milling machine.

Die erfindungsgemäße Rangiervorrichtung verfügt vorzugsweise über eine Lenkung an sämtlichen Rädern, vorzugsweise an allen vier Rädern, woraus sich ein enger Rangierbereich ergibt. Der Lenkwinkel, vorzugsweise an sämtlichen Rädern, ist vorzugsweise 90°, so dass sich die mit der Fräseinrichtung beladene Rangiervorrichtung unter der Fräsmaschine gut rangieren lässt. Derartige Lenkvorrichtungen mit einem großen Lenkwinkel sind aus der EP 1 522 632 B1 und der EP 1 841 637 B1 der Anmelderin bekannt.The shunting device according to the invention preferably has a steering on all wheels, preferably on all four wheels, resulting in a narrow Rangierbereich. The steering angle, preferably at all wheels, is preferably 90 °, so that loaded with the milling device shunting can be ranked well under the milling machine. Such steering devices with a large steering angle are from the EP 1 522 632 B1 and the EP 1 841 637 B1 the applicant known.

Im Folgenden wird ein Ausführungsbeispiel der Erfindung unter Bezugnahme auf die Zeichnungen näher erläutert.In the following an embodiment of the invention will be explained in more detail with reference to the drawings.

Die Figuren 1A und 1B bis 4A und 4B zeigen eine Seitenansicht und eine Draufsicht der Rangiervorrichtung in den verschiedenen Arbeitspositionen. Die Rangiervorrichtung ist als ein von mehreren Rädern getragenes Fahrzeug mit einer Aufnahmeeinheit für in den Figuren 1A, 1B bis 4A, 4B nicht dargestellte Fräseinrichtungen unterschiedlicher Arbeitsbreite ausgebildet.The Figures 1A and 1B to 4A and 4B show a side view and a plan view of the shunting in the various working positions. The shunting device is as a multi-wheeled vehicle with a receiving unit for in the Figures 1A . 1B to 4A . 4B not shown milling devices of different working width formed.

Die Rangiervorrichtung ist eine selbstfahrende Vorrichtung. Sie weist einen langgestreckten Transportrahmen 1 auf, der in Längsrichtung verlängerbar ist. In den Fig. 1A und 1B ist der Transportrahmen 1 in der auf die maximale Länge ausgefahrenen Position dargestellt, während die Fig. 2A und 2B den Transportrahmen in der auf die minimale Länge eingefahrenen Position zeigen. Der Transportrahmen 1 kann aber auch auf bestimmte Längen ausgefahren werden, die zwischen diesen beiden Positionen liegen. Damit kann die Länge des Transportrahmens auf die Arbeitsbreite der zu montierenden Fräseinrichtung genau eingestellt werden.The maneuvering device is a self-propelled device. It has an elongate transport frame 1 which is extendible in the longitudinal direction. In the Fig. 1A and 1B is the transport frame 1 in the extended to the maximum length Position shown while the FIGS. 2A and 2B show the transport frame in the retracted to the minimum length position. The transport frame 1 can also be extended to certain lengths that lie between these two positions. Thus, the length of the transport frame can be set exactly to the working width of the milling device to be mounted.

Obwohl die Rangiervorrichtung so ausgebildet ist, dass sie grundsätzlich keine bevorzugte Fahrtrichtung hat, wird das in den Zeichnungen linke Ende der Rangiervorrichtung als vorderes Ende und das rechte Ende als hinteres Ende bezeichnet.Although the shunting device is designed so that it basically has no preferred direction of travel, the left end of the shunting device in the drawings is referred to as the front end and the right end as the rear end.

Der Transportrahmen 1 der Rangiervorrichtung besteht aus zwei äußeren Grundrahmen 1A und 1 B sowie einem dazwischen liegenden Innenrahmen 1C. Der vordere Grundrahmen 1 A und der hintere Grundrahmen 1B weisen jeweils in Längsrichtung des Transportrahmens 1 verlaufende seitliche Hohlprofile 2A und 2B auf, die mit quer verlaufenden Profilen 3A, 3B und 4A und 4B verbunden sind. Der Innenrahmen 1C weist zwei in Längsrichtung verlaufende seitliche Träger 5A, 5B auf, die längsverschiebbar in den Hohlprofilen 2A und 2B der äußeren Grundrahmen 1A und 1B geführt sind. Folglich lässt sich der Transportrahmen 1 in der Länge teleskopartig verlängern bzw. verkürzen. Die Träger 5A, 5B des Innenrahmen 1C weisen eine Reihe von Bohrungen 6 auf, die mit Bohrungen 7 an den Hohlprofilen 2A, 2B der Grundrahmen 1 A, 1 B zur Deckung gebracht werden können. Die Grundrahmen 1A, 1B und der Innenrahmen 1C werden mittels Bolzen 8 gegen Verschieben gesichert, die in den miteinander fluchtenden Bohrungen 6, 7 von Grund- und Innenrahmen sitzen.The transport frame 1 of the shunting device consists of two outer base frames 1A and 1B and an inner frame 1C therebetween. The front base frame 1 A and the rear base frame 1B each have in the longitudinal direction of the transport frame 1 extending lateral hollow sections 2A and 2B, which are connected to transverse profiles 3A, 3B and 4A and 4B. The inner frame 1C has two longitudinal side supports 5A, 5B longitudinally slidably guided in the hollow sections 2A and 2B of the outer base frames 1A and 1B. Consequently, the transport frame 1 can be telescopically lengthened or shortened in length. The carrier 5A, 5B of the inner frame 1C have a series of holes 6, which can be brought to cover with holes 7 on the hollow sections 2A, 2B of the base frame 1 A, 1 B. The base frame 1A, 1B and the inner frame 1C are secured by means of bolts 8 against displacement, sitting in the aligned holes 6, 7 of the base and inner frame.

Die Rangiervorrichtung weist zwei Vorderräder 9A, 9B und zwei Hinterräder 10A, 10B, auf. Die Räder 9A, 9B und 10A, 10B, sind an parallel zur Längsrichtung des Transportrahmens 1 ausgerichteten Schwingen 11A bis 11D befestigt, die um eine quer zur Fahrtrichtung verlaufende im Wesentlichen waagerechten Rotationsachse schwenkbar an den Längsseiten des Transportrahmens gelagert sind. Die Schwingen 11A und 11C am vorderen Grundrahmen 1A bzw. die Schwingen 11B und 11D am hinteren Grundrahmen 1B sind über quer verlaufende Profile 24A und 24B bzw. 25A und 25B miteinander verbunden. Das eine Ende jeder Schwinge 11A bis 11D ist schwenkbar an einer Konsole 12A, 12B befestigt, die an der Unterseite eines Hohlprofils 2A, 2B eines Grundrahmens 1A, 1B befestigt ist. An den anderen Enden der Schwingen 11A bis 11D sind die Räder 9A, 9B, 10A, 10B schwenkbar gelagert.The shunting device has two front wheels 9A, 9B and two rear wheels 10A, 10B. The wheels 9A, 9B and 10A, 10B are mounted on parallel to the longitudinal direction of the transport frame 1 aligned wings 11A to 11D, which are mounted about a transverse to the direction of travel substantially horizontal axis of rotation pivotally mounted on the longitudinal sides of the transport frame. The rockers 11A and 11C on the front base frame 1A and the rockers 11B and 11D on the rear base frame 1B are connected to each other via transverse profiles 24A and 24B and 25A and 25B, respectively. The one end of each rocker 11A to 11D is pivotally mounted on a bracket 12A, 12B fixed to the underside of a hollow section 2A, 2B of a base frame 1A, 1B. At the other ends of the rockers 11A to 11D, the wheels 9A, 9B, 10A, 10B are pivotally supported.

Die vordere und hintere Lenkung umfassen jeweils vordere bzw. hintere Radkonsolen 14A, 14B bzw. 14C und 14D und eine vordere und hintere Kolben-Zylinder-Anordnung 15A bzw. 15B sowie eine vordere und hintere Spurstange 16A bzw. 16B. Durch Ein- bzw. Ausfahren des Kolbens der vorderen bzw. hinteren Kolben-Zylinder-Anordnung 15A bzw. 15B können Vorder- bzw. Hinterräder 9A, 9B bzw. 10A, 10B gelenkt werden. Die Rangiervorrichtung hat somit insbesondere bei zusammen geschobenen Grund- und Innenrahmen einen engen Rangierbereich.The front and rear steering include front and rear wheel consoles 14A, 14B and 14C and 14D, respectively, and front and rear piston-and-cylinder assemblies 15A and 15B, and front and rear tie rods 16A and 16B, respectively. By extending or retracting the piston of the front and rear piston-cylinder assemblies 15A and 15B, respectively, front and rear wheels 9A, 9B and 10A, 10B can be steered. The maneuvering device thus has a narrow maneuvering area, especially when the base and inner frames are pushed together.

Die seitlichen Schwingen 11A bis 11 D der Radaufhängung erlauben das Anheben bzw. Absenken des Transportrahmens 1 der Rangiervorrichtung aus einer abgesenkten Position in eine angehobene Position. Nachfolgend wird in Bezug auf den unmittelbaren Einsatz bei der Montage bzw. Demontage die abgesenkte Position als Rangierposition und die angehobene Position als Montageposition bezeichnet. Beim Umsetzen, Verladen oder Transportieren der Rangiervorrichtung kann es ebenfalls erforderlich sein, die angehobene Position bzw. die abgesenkte Position zu verwenden, oder zwischen diesen zu wechseln.The side wings 11A to 11D of the suspension allow the lowering or lowering of the transport frame 1 of the maneuvering device from a lowered position to a raised position. Hereinafter, with respect to the immediate use in the assembly and disassembly, the lowered position is referred to as a maneuvering position and the raised position as a mounting position. When transferring, loading or transporting the maneuvering device, it may also be necessary to use the raised position or the lowered position, or to switch between them.

Den vorderen Schwingen 11A, 11C sind vordere Kolben-Zylinder-Anordnungen 17A, 17C und den hinteren Schwingen 11 B, 11D sind hintere Kolben-Zylinder-Anordnungen 17B, 17D zugeordnet, die sich jeweils oberhalb der Hohlprofile der Grundträger in Längsrichtung des Transportrahmens erstrecken. Die Zylinder der Kolben-Zylinder-Anordnungen 17A bis 17D sind schwenkbar an den freien Enden der Schwingen 11A bis 11D und die Kolben der Kolben-Zylinder-Anordnungen 17A bis 17D sind schwenkbar an den inneren Enden der Hohlprofile der Grundrahmen 1A, 1B befestigt. Durch Ein- bzw. Ausfahren der den Schwingen zugeordneten Kolben-Zylinder-Anordnungen kann der Transportrahmen zwischen der abgesenkten Rangierposition und der angehobenen Montageposition verfahren werden. Die Fig. 3A und 3B zeigen die Rangiervorrichtung in der Rangierposition, während die Fig. 4A und 4B die Rangiervorrichtung in Montageposition zeigen. In der Rangierposition zeichnet sich die Rangiervorrichtung durch eine besonders geringe Bauhöhe aus.The front rockers 11A, 11C are front piston-cylinder assemblies 17A, 17C and the rear rockers 11B, 11D are rear piston-cylinder assemblies 17B, 17D each extending above the hollow profiles of the base beams in the longitudinal direction of the transport frame. The cylinders of the piston-and-cylinder assemblies 17A-17D are pivotally mounted at the free ends of the rockers 11A-11D and the pistons of the piston-cylinder assemblies 17A-17D are pivotally attached to the inner ends of the hollow profiles of the base frames 1A, 1B. By retracting or extending the swing associated piston-cylinder assemblies of the transport frame between the lowered maneuvering position and the raised mounting position can be moved. The FIGS. 3A and 3B show the shunting in the Rangierposition while the FIGS. 4A and 4B the shunting device in Show mounting position. In the shunting position, the shunting device is characterized by a particularly low height.

Die Aufnahmeeinheit 18 der Rangiervorrichtung für die Aufnahme der Fräseinrichtung weist eine vordere Aufnahme 18A auf, die am äußeren Ende des vorderen Grundrahmens angeordnet ist, und eine hintere Aufnahme 18B auf, die am äußeren Ende des hinteren Grundrahmens angeordnet ist. Diese beiden Aufnahmen 18A, 18B liegen an den Grundrahmen 1A, 1B möglichst tief. Sie weisen jeweils eine Auflagefläche 19A, 19B und einen stufenförmigen Absatz 19C, 19D auf, so dass sich die vorderen bzw. hinteren Enden der Fräseinrichtung in die Auflagen einsetzen lassen.The receiving unit 18 of the mower-receiving shovel has a front receptacle 18A disposed at the outer end of the front base frame and a rear receptacle 18B disposed at the outer end of the rear base frame. These two receptacles 18A, 18B are as deep as possible on the base frame 1A, 1B. They each have a bearing surface 19A, 19B and a step-shaped shoulder 19C, 19D, so that the front and rear ends of the milling device can be inserted into the pads.

Für die Rangiervorrichtung ist eine möglichst geringe Bauhöhe entscheidend. Daher sind die Räder 9A, 9B und 10A, 10B an den Schwingen 11A bis 11D derart befestigt, dass die Oberseite der Räder in der Rangierposition im Wesentlichen auf der Höhe der Aufnahmeeinheit 18 liegen. Auch die Kolben-Zylinder-Anordnungen 17A bis 17D zum Verschwenken der Schwingen 11 A bis 11 D sind derart an dem Transportrahmen befestigt, dass sich die Kolben-Zylinder-Anordnungen in der Höhe nicht über die Aufnahmeeinheit 18 hinaus erstrecken. Die Aufnahmeeinheit 18 liegt daher im Wesentlichen auf der Höhe der Räder oder niedriger.For shunting the lowest possible height is crucial. Therefore, the wheels 9A, 9B and 10A, 10B are fixed to the rockers 11A to 11D such that the upper surfaces of the wheels in the shunting position are substantially at the level of the receiving unit 18. Also, the piston-cylinder assemblies 17A to 17D for pivoting the rockers 11A to 11D are secured to the transport frame such that the piston-cylinder assemblies do not extend beyond the receiving unit 18 in height. The receiving unit 18 is therefore substantially at the height of the wheels or lower.

Bei dem vorliegenden Ausführungsbeispiel werden die Räder 9A, 9B und 10A, 10B von in die Radnaben integrierten Hydraulikmotoren angetrieben, die in den Fig. nicht dargestellt sind. Die Einheit für die Versorgung der Hydraulikmotoren und der Kolben-Zylinder-Anordnungen mit Hydrauliköl wird nachfolgend als Steuer- und Antriebseinheit 20 bezeichnet. Die Steuer- und Antriebseinheit 20, die mehrere Aggregate umfassen kann, ist am hinteren Ende des hinteren Grundrahmens 1B hinter der hinteren Auflage 18B der Aufnahmeeinheit 18 angeordnet. Da beim Einsatz der Rangiervorrichtung für das Unterfahren unter die Fräsmaschine nur die Bauhöhe im Bereich der Aufnahmeeinheit 18 von Bedeutung ist, können sich diese Aggregate in der Höhe über die Aufnahmeeinheit hinaus erstrecken.In the present embodiment, the wheels 9A, 9B and 10A, 10B are driven by hydraulic motors integrated in the wheel hubs, which are not shown in the figures. The unit for supplying the hydraulic motors and the piston-cylinder assemblies with hydraulic oil is hereinafter referred to as the control and drive unit 20. The control and drive unit 20, which may comprise a plurality of units, is arranged at the rear end of the rear base frame 1 B behind the rear support 18 B of the receiving unit 18. Since only the overall height in the area of the receiving unit 18 is of importance when using the shunting device for driving under the milling machine, these units can extend in height beyond the receiving unit.
