Description

Vorrichtung zum Transportieren einer BaumaschineDevice for transporting a construction machine
Technisches GebietTechnical field
Die Erfindung bezieht sich auf eine Vorrichtung zum Transportieren einer mit einem Raupenfahrwerk ausgestatteten, einen Räumschild aufweisenden, selbstfahrenden Baumaschine, insbesondere eines Raupenbaggers, mit einem von der Baumaschine her angetriebenen Räderfahrwerk.The invention relates to a device for transporting a self-propelled construction machine equipped with a caterpillar undercarriage, with a dozer blade, in particular a crawler excavator, with a wheel undercarriage driven by the construction machine.
Stand der TechnikState of the art
Selbstfahrende Baumaschinen mit einem Raupenfahrwerk benötigen für die Überstellung von einer Baustelle zu einer anderen Baustelle oder innerhalb größerer Baustellen von einem Arbeitsplatz zu einem anderen ein Transportfahrzeug wie einen Tieflader oder LKW, wodurch hohe Zusatzkosten und oft Koordinationsprobleme verursacht werden. Derartige Überstellungen sind zudem mit einem hohen zeitlichen und personellen Aufwand verbunden. Überstellungen von mehreren hundert Metern innerhalb einer Baustelle werden deshalb mit dem Raupenfahrwerk vorgenommen, welches dadurch einem erhöhten Verschleiß unterliegt, was wiederum hohe Wartungskosten verursacht. Zudem ist die Transportgeschwindigkeit sehr gering, weil die Maximalgeschwindigkeit einer derartigen Baumaschine mit Raupenfahrwerk bei lediglich rund 4 km/h liegt. Da das Befahren von Asphaltstraßen mit Raupenfahrzeugen, die mit Stahlketten ausgestattet sind generell verboten ist, werden insbesondere kleinere und mittlere Baumaschinen meist mit Kunststoffraupen ausgerüstet, die gegenüber Stahlketten allerdings weniger widerstandsfähig sind, ebenfalls einem höheren Verschleiß unterliegen und schwer zu entsorgen sind. Ein weiterer Nachteil von kurzen Überstellungsfahrten auf Asphaltstraßen zwischen zwei Baustellen liegt darin, daß dabei durch das verschmutzte Raupenfahrwerk erhebliche Mengen Schmutz auf die Straße verfrachtet werden, so daß ein nachträgliches Säubern der Fahrbahn notwendig wird.Self-propelled construction machines with a crawler chassis require a transport vehicle such as a flatbed trailer or truck to transfer from one construction site to another construction site or within larger construction sites from one workplace to another, which causes high additional costs and often coordination problems. Such transfers are also associated with a high expenditure of time and personnel. Transfers of several hundred meters within a construction site are therefore carried out with the crawler chassis, which is subject to increased wear, which in turn causes high maintenance costs. In addition, the transport speed is very low because the maximum speed of such a construction machine with a crawler chassis is only around 4 km / h. Since driving on asphalt roads with caterpillar vehicles that are equipped with steel chains is generally forbidden, small and medium-sized construction machines in particular are usually equipped with plastic caterpillars, which, however, are less resistant to steel chains, are also subject to greater wear and tear and are difficult to dispose of are. Another disadvantage of short transfer journeys on asphalt roads between two construction sites is that the dirty caterpillar undercarriage brings considerable amounts of dirt onto the road, so that the roadway has to be cleaned afterwards.
Um derartige Baumaschinen in einfacher Weise von einem zum anderen Einsatzort verfrachten zu können, ist es bekannt (DE 196 34 585 A1) eine Lafette zum Transportieren einer mit einem Raupenfahrwerk ausgestatteten Baumaschine vorzusehen, wobei die Baumaschine ein Hydrauliksystem aufweist, das mit einer hydraulisch antreibbaren Antriebsachse der Lafette und einer hydraulisch antreibbaren Lenkachse der Lafette kuppelbar ist. Der Hydraulikantrieb der Baumaschine dient dabei dazu, die Lafette anzutreiben und zu lenken. Die Lafette stellt ein baulich einfach gestaltetes Fahrzeug dar, auf das die Baumaschine bei Bedarf auffährt, wonach die Baumaschine auf der Lafette gesichert und anschließend mit der Lafette hydraulisch gekoppelt wird. Danach kann die Baumaschine mittels der Lafette auf dem Straßenweg unmittelbar in rascher Weise von einem Einsatzort zum anderen fahren. Von Nachteil ist bei dieser bekannten Vorrichtung allerdings, daß die Baumaschine vor dem Verfrachten von einem Einsatzort zum anderen stets in umständlicher Weise auf die Lafette aufgeladen, dort gesichert und an die Hydraulik angeschlossen werden muß, so daß auf derartige Systeme im allgemeinen verzichtet und die Baumaschine mit Hilfe des Raupenfahrwerkes verfahren wird. Zudem ergibt sich durch die besondere Konstruktion der Lafette ein besonders hoher Schwerpunkt der Gesamtkonstruktion, worunter insbesondere die Fahrstabilität leidet. Außerdem ist die Anschaffung einer derartigen Lafette mit verhältnismäßig hohen Kosten verbunden, so daß sich die Anschaffung meist nicht rechnet.In order to be able to easily transport such construction machines from one place of use to another, it is known (DE 196 34 585 A1) to provide a carriage for transporting a construction machine equipped with a crawler chassis, the construction machine having a hydraulic system which has a hydraulically drivable drive axle the carriage and a hydraulically driven steering axis of the carriage can be coupled. The hydraulic drive of the construction machine serves to drive and steer the carriage. The carriage is a structurally simple vehicle that the construction machine can drive onto if necessary, after which the construction machine is secured on the carriage and then hydraulically coupled to the carriage. The construction machine can then move quickly and quickly from one location to another on the road using the carriage. The disadvantage of this known device, however, is that the construction machine must always be loaded onto the carriage in a cumbersome manner before being shipped from one place of use to another, secured there and connected to the hydraulics, so that such systems are generally dispensed with and the construction machine with the help of the crawler track. In addition, the special construction of the carriage results in a particularly high focus of the overall construction, which in particular affects the driving stability. In addition, the purchase of such a carriage is associated with relatively high costs, so that the purchase usually does not pay off.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs geschilderten Art zu schaffen, die mit verhältnismäßig einfachen Mitteln einen raschen Transport der Baumaschine von einem Einsatzort zum anderen ermöglicht und mit der die Baumaschine rasch ausgerüstet werden kann. Die Erfindung löst diese Aufgabe dadurch, daß das Räderfahrwerk zwei an einem Ende der Baumaschine, an gegenüberliegenden Seiten des Räumschildes angeordnete und an den Räumschild kuppelbare Räder und wenigstens ein dem anderen Ende der Baumaschine zugeordnetes Laufrad umfaßt, wobei Räder und Laufrad mittels Hubeinrichtungen in eine die Baumaschine mit dem Raupenfahrwerk von der Fahrbahn abhebende Fahrstellung verlagerbar sind.The invention is therefore based on the object of providing a device of the type described at the outset which, with relatively simple means, enables the construction machine to be transported quickly from one place of use to the other and with which the construction machine can be quickly equipped. The invention solves this problem in that the wheel chassis comprises two wheels arranged at one end of the construction machine, on opposite sides of the dozer blade and which can be coupled to the dozer blade, and at least one wheel assigned to the other end of the construction machine, the wheels and the wheel being lifted into one by means of lifting devices Construction machine with the crawler chassis can be shifted from the driving position lifting.
Kern der Erfindung ist somit ein vorzugsweise mittels Schnellkupplungen an den Räumschild der Baumaschine kuppelbares Räderpaar, das mit Hilfe der Hydraulik des Räumschildes nach dem Ankuppeln in eine die Baumaschine mit dem Raupenfahrwerk von der Fahrbahn abhebende Fahrstellung verlagerbar ist. Das dem anderen Ende der Baumaschine zugeordnete Laufrad ist beispielsweise im Heckbereich der Baumaschine zwischen den Raupen am Raupenfahrwerk befestigt, und vorzugsweise hydraulisch aus seiner angehobenen Ruhelage in seine das Raupenfahrwerk von der Fahrbahn abhebende Fahrstellung verlagerbar. Das Laufrad könnte allerdings auch rein schwerkraftbedingt gegen die Fahrbahn hin absenkbar sein, wobei die Baumaschine in diesem Fall beispielsweise mit einem Baggerarm an der Laufradseite soweit von der Fahrbahn abgehoben werden müßte, bis das Laufrad in seiner Fahrstellung einrastet. Zum raschen Transport der Baumaschine von einem Einsatzort zum anderen müssen lediglich das Räderfahrwerk an den Räumschild angekuppelt, sowie Räumschild und Laufrad in die Fahrstellung verlagert und gegebenenfalls Hydraulikanschlüsse für den Fahrantrieb der an den Räumschild kuppelbaren Räder an die Baumaschine angeschlossen werden, bevor die Baumaschine mit dem Räderfahrwerk verfahren werden kann. Die wesentlichen Vorteile der Erfindung liegen darin, daß Überstellungen der Baumaschine im Nahbereich ohne zusätzliche Transportfahrzeuge und zusätzliches Personal möglich sind, wobei zusätzlich das Raupenfahrwerk geschont wird und keine Asphaltstraßen verschmutzt werden, die nachträglich gereinigt werden müßten. Das erfindungsgemäße Räderfahrwerk kann innerhalb kürzester Zeit abgestellt oder an die Baumaschine angekuppelt werden und behindert den Arbeitsbetrieb der Baumaschine in keiner Weise. Grundsätzlich könnten die an den Räumschild kuppelbaren Räder je für sich am Räumschild befestigt werden, es empfiehlt sich aber, wenn die zwei an dem Räumschild kuppelbaren Räder auf einem gemeinsame Fahrschemel angeordnet sind, der mittels wenigstens einer Kupplung am Räumschild lösbar befestigt ist. Durch diese Maßnahme ist gewährleistet, daß das Räderfahrwerk mit besonders wenig Aufwand und in sehr kurzer Zeit verfügbar ist und die Umrüstzeiten zwischen Räder- und Raupenfahrwerk minimal gehalten werden.The core of the invention is therefore a pair of wheels which can preferably be coupled to the dozer blade of the construction machine by means of quick-release couplings and which, after coupling, can be displaced into a driving position lifting the construction machine with the crawler chassis from the roadway by means of the hydraulics of the dozer blade. The wheel assigned to the other end of the construction machine is fastened, for example, in the rear region of the construction machine between the caterpillars on the crawler chassis, and can preferably be displaced hydraulically from its raised rest position into its driving position lifting the crawler chassis from the road. The impeller could, however, also be lowered against the roadway purely due to gravity, in which case the construction machine would have to be lifted off the roadway, for example with an excavator arm, until the impeller locks in its driving position. To quickly transport the construction machine from one place of use to the other, all that has to be done is to couple the wheel undercarriage to the dozer blade, move the dozer blade and impeller to the driving position and, if necessary, connect hydraulic connections for driving the wheels that can be coupled to the dozer blade to the construction machine before the construction machine with the Wheel chassis can be moved. The main advantages of the invention are that transfers of the construction machine in the vicinity are possible without additional transport vehicles and additional personnel, the caterpillar chassis being additionally protected and no asphalt roads being contaminated which would have to be cleaned subsequently. The wheel undercarriage according to the invention can be switched off or coupled to the construction machine in the shortest possible time and in no way hinders the working operation of the construction machine. In principle, the wheels that can be coupled to the dozer blade could each be attached to the dozer blade, but it is recommended that the two wheels that can be coupled to the dozer blade are arranged on a common subframe that is detachably attached to the dozer blade by means of at least one coupling. This measure ensures that the wheel undercarriage is available with particularly little effort and in a very short time and that the changeover times between the wheel and crawler undercarriage are kept to a minimum.
Als besonders Vorteilhaft hat es sich erwiesen, wenn die zwei an den Räumschild kuppelbaren Räder mit je einem eigenen von der Baumaschine her versorgten Antriebsmotor ausgestattet sind, da sich dadurch verbesserte Fahreigenschaften ergeben. Zusätzlich können zwischen Räumschild und Räderfahrwerk Schnellkupplungen für die Versorgungsleitungen der Antriebsmotoren vorgesehen sein, um die Rüstzeit noch weiter zu verringern.It has proven to be particularly advantageous if the two wheels which can be coupled to the dozer blade are each equipped with their own drive motor supplied by the construction machine, since this results in improved driving properties. In addition, quick couplings for the supply lines of the drive motors can be provided between the dozer blade and the wheel chassis in order to further reduce the set-up time.
Besonders einfache Konstruktionsverhältnisse ergeben sich, wenn die Antriebsmotoren der Räder und die Motoren der Raupen vorzugsweise wechselweise an die Betriebsleitungen des Antriebes der jeweils zugeordneten Raupe anschließbar sind. Dadurch müssen keine zusätzlichen Steuergeräte für den Antrieb des Räderfahrwerkes vorgesehen werden, da dieses in diesem Fall in einfacher Weise von der Fahrkabine der Baumaschine her mit den Steuermitteln des Raupenfahrwerkes betätigbar ist. Zum wechselweisen anschließen des Raupen- oder Räderfahrwerkes an die Betriebsleitungen der Baumaschine können Umschaltventile vorgesehen sein. Ist das Räderfahrwerk nach Art des Raupentriebes angesteuert, empfiehlt es sich, das Laufrad als Nachlaufrad auszubilden um kein unbestimmtes mechanisches System zu erhalten.'Particularly simple constructional relationships result if the drive motors of the wheels and the motors of the caterpillars can preferably be connected alternately to the operating lines of the drive of the respectively assigned caterpillar. As a result, no additional control devices have to be provided for driving the wheel undercarriage, since in this case it can be actuated in a simple manner from the driving cabin of the construction machine with the control means of the crawler undercarriage. Switch valves can be provided for alternately connecting the crawler or wheel chassis to the operating lines of the construction machine. If the wheel undercarriage is controlled according to the type of caterpillar drive, it is advisable to design the impeller as a trailing wheel in order not to get an undefined mechanical system. '
Alternativ zu dem an den Räumschild ankuppelbaren Räderpaar könnte auch das Laufrad von der Baumaschine her angetrieben sein, das in diesem Fall vorzugsweise auch von der Baumaschine her lenkbar ausgebildet ist. Antrieb und Lenkung erfolgen in diesem Fall über das Laufrad, wohingegen die an den Räumschild kuppelbaren Räder lediglich als Laufrollen ausgebildet sind. Eine weitere alternative Ausgestaltungsform der Erfindung ergibt sich, wenn das Laufrad an einem Kranausleger der Baumaschine, vorzugsweise an der Werkzeugaufnahme, angeordnet ist. Das Laufrad braucht zum Verfahren der Baumaschine somit lediglich am Kranausleger befestigt werden, wonach die Baumaschine mittels des Kranauslegers von der Fahrbahn abgehoben werden kann. Das Laufrad ist entweder als Nachlaufrad oder von der Baumaschine her angetrieben, gegebenenfalls auch lenkbar, ausgebildet.As an alternative to the pair of wheels that can be coupled to the dozer blade, the impeller could also be driven by the construction machine, which in this case is preferably also designed to be steerable by the construction machine. In this case, drive and steering take place via the impeller, whereas the wheels that can be coupled to the dozer blade are only designed as rollers. Another alternative embodiment of the invention results when the impeller is arranged on a crane boom of the construction machine, preferably on the tool holder. To move the construction machine, the impeller therefore only needs to be attached to the crane boom, after which the construction machine can be lifted off the road by means of the crane boom. The impeller is either designed as a trailing wheel or driven by the construction machine, possibly also steerable.
Die Lenkung kann in jedem vorgenannten Fall auch über den Drehkranz der Baumaschine, nach Art einer Knicklenkung, erfolgen.In each of the aforementioned cases, the steering can also take place via the slewing ring of the construction machine, in the manner of an articulated steering.
Da beim Transport der Baumaschine von einem Einsatzort zum anderen des öfteren verschiedenste Werkzeuge wie Schaufeln od. dgl. bzw. Kraftstoff oder Hydrauliköl mittransportiert werden müssen, hat es sich als vorteilhaft erwiesen, wenn der Fahrschemel einen vorzugsweise nach oben hin offenen Behälter aufnimmt oder trägt, welcher Behälter die zusätzlich erforderlichen Betriebsmittel in einfacherWeise aufnehmen kann.Since various tools such as shovels or the like or fuel or hydraulic oil often have to be transported when the construction machine is transported from one place of use to another, it has proven to be advantageous if the subframe holds or carries a container that is preferably open at the top, which container can easily accommodate the additional equipment required.
Soll der Fahrschemel möglichst einfach und rasch an die Baumaschine angekuppelt werden können, empfiehlt es sich, wenn dem Fahrschemel wenigstens ein Stützrad zugehört, das den von der Baumaschine abgekuppelten Fahrschemel in seiner Kupplungsstellung sichert. Damit wird sichergestellt, daß sich der Fahrschemel stets in der richtigen Kupplungsstellung befindet und das Baufahrzeug lediglich mit an die Kupplungshöhe angepaßtem Räumschild an den Fahrschemel heranfahren und an diesen ankuppeln muß, wonach der Räumschild abgesenkt werden kann und sich das Stützrad sowie die Raupen von der Fahrbahn abheben.If the subframe should be able to be coupled to the construction machine as simply and quickly as possible, it is advisable for the subframe to have at least one support wheel which secures the subframe uncoupled from the construction machine in its coupling position. This ensures that the subframe is always in the correct coupling position and the construction vehicle only has to approach and couple to the subframe with the dozer blade adapted to the coupling height, after which the dozer blade can be lowered and the jockey wheel and caterpillars are off the road take off.

Die zwei an den Räumschild 2 mit dem Fahrschemel 7 angekuppelten Räder 5 sind mit je einem eigenen, von der Baumaschine her versorgten Antriebsmotor 9 ausgestattet, welche wechselweise mit den nicht näher dargestellten Motoren der Raupen 10 mittels Versorgungsleitungen 12 an die Betriebsleitungen des Antriebes der jeweils zugeordneten Raupe 10 anschließbar sind.A device for transporting a self-propelled crawler excavator 3 equipped with a crawler chassis 1 and having a dozer blade 2 comprises a wheel chassis 4 which is driven by the construction machine. The wheel chassis 4 in turn has and arranges two at one end of the construction machine, on opposite sides of the dozer blade 2 the dozer blade on detachable wheels 5 and an impeller 6 assigned to the other end of the construction machine, which is designed as a trailing wheel according to the exemplary embodiment shown. The two wheels 5 which can be coupled to the dozer blade 2 are arranged on a common subframe 7 which can be detachably fastened to the dozer blade 2 by means of couplings 8. The two wheels 5 coupled to the clearing blade 2 with the subframe 7 are each equipped with their own drive motor 9, supplied by the construction machine, which alternately with the motors of the caterpillars 10, not shown in more detail, by means of supply lines 12 to the operating lines of the drive of the respectively assigned Caterpillar 10 can be connected.
Der Fahrschemel trägt einen nach oben hin offenen Behälter 13 zur Aufnahme verschiedenster Betriebsmittel wie Schaufeln od. dgl. mehr. Zudem gehört dem Fahrschemel 7 ein Stützrad 14 zu, das den von der Baumaschine abgekuppelten Fahrschemel 7 in seiner Kupplungsstellung (Fig. 1) sichert, wodurch ein rasches An- und Abkuppeln des Fahrschemels von der Baumaschine gewährleistet ist. Zum Ankuppeln muß das Baufahrzeug lediglich mit an die Kupplungshöhe angepaßtem Räumschild 2 an den Fahrschemel 7 heranfahren und an diesen ankuppeln, wobei zwischen Baumaschine und Fahrschemel 7 vorzugsweise Schnellkupplungen für die Versorgungsleitungen 12 der Antriebsmotoren 9 vorgesehen sind. Werden die Räder 5 samt dem Fahrschemel 7 mit der Hydraulik 15 des Räumschildes 2 in ihre die Baumaschine mit dem Raupenfahrwerk 1 von der Fahrbahn 16 abhebenden Fahrstellung verlagert, so hebt zusätzlich das Stützrad 14 von der Fahrbahn 16 ab, so daß dieses während der Fahrt mit dem Räderfahrwerk geschont wird. Das Laufrad 6 wird gemäß dem dargestellten Ausführungsbeispiel mittels einer gesonderten Hydraulik aus seiner Ruhelage (Fig. 1) in seine das Raupenfahrwerk 1 von der Fahrbahn 16 abhebende Fahrstellung verlagert.The subframe carries a container 13 which is open at the top and can hold a wide variety of operating resources such as shovels or the like. In addition, the subframe 7 includes a support wheel 14, which secures the subframe 7 uncoupled from the construction machine in its coupling position (FIG. 1), thereby a rapid coupling and uncoupling of the subframe from the construction machine is guaranteed. To couple the construction vehicle only needs to approach and couple to the subframe 7 with the clearing plate 2 adapted to the coupling height, with quick couplings for the supply lines 12 of the drive motors 9 preferably being provided between the construction machine and the subframe 7. If the wheels 5 together with the subframe 7 with the hydraulics 15 of the dozer blade 2 are shifted into their construction position with the caterpillar undercarriage 1 from the carriageway 16, the support wheel 14 also lifts off the carriageway 16, so that it moves with it during the journey the wheel chassis is protected. According to the exemplary embodiment shown, the running wheel 6 is shifted from its rest position (FIG. 1) into its driving position lifting the crawler chassis 1 from the road 16 by means of separate hydraulics.
Die Antriebsmotoren 9 der Räder 5 erhalten im Fahrbetrieb die im Arbeitsbetrieb den Motoren der linken bzw. rechten Raupenkette zugedachte Ölmenge, wodurch es möglich wird, die mit dem Räderfahrwerk ausgestattete Baumaschine mit der Raupensteuerung entweder vorwärts, rückwärts oder links bzw. rechts fahren zu lassen. Das als Nachlaufrad ausgebildete Laufrad 6 hat sich dabei den jeweiligen Fahrsituationen selbsttätig an.The drive motors 9 of the wheels 5 receive the amount of oil intended for the motors of the left or right caterpillar track during operation, which makes it possible to let the construction machine equipped with the crawler track drive with the caterpillar control either forward, backward or left or right. The wheel 6, which is designed as a trailing wheel, automatically adjusts to the respective driving situations.
Gemäß dem Ausführungsbeispiel nach Fig. 4 ist das Laufrad 6 an der Werkzeugaufnahme 17 des Kranauslegers 18 des Raupenbaggers 3 angeordnet ist. Das Laufrad 6 braucht zum Verfahren des Raupenbaggers 3 somit lediglich am Kranausleger 18 an Stelle des Werkzeuges, beispielsweise einer Schaufel od. dgl., befestigt werden, wonach das Raupenfahrwerk 1 des Raupenbaggers 3 mittels des Kranauslegers 18 von der Fahrbahn abgehoben werden kann. Das Laufrad ist als Nachlaufrad ausgebildet, kann aber auch vom Raupenbagger 3 her angetrieben, gegebenenfalls auch lenkbar ausgebildet sein.4, the impeller 6 is arranged on the tool holder 17 of the crane boom 18 of the crawler excavator 3. To move the crawler excavator 3, the impeller 6 therefore only needs to be attached to the crane boom 18 instead of the tool, for example a shovel or the like, after which the crawler chassis 1 of the crawler excavator 3 can be lifted off the road by means of the crane boom 18. The impeller is designed as a trailing wheel, but can also be driven by the crawler excavator 3, and can optionally also be designed to be steerable.
Die Lenkung kann bei von der Fahrbahn abgehobenem Raupenfahrwerk 1 grundsätzlich auch über den Drehkranz 19 des Raupenbaggers 3, nach Art einer Knicklenkung, erfolgen. When the crawler chassis 1 is lifted off the road, the steering can in principle also take place via the slewing ring 19 of the crawler excavator 3, in the manner of an articulated steering.
