Abstract

The vehicle has a base plate (16) supported on a lower carriage. Two vertical hydraulic cylinders are fastened at a part of an upper carriage. Piston rods (20) of the cylinders have retaining plates that form a load carrying point. The retaining plates are retracted into a recess from connection rods arranged at the base plate, to reach slots. The piston rods extend over the retaining plates, and another load carrying point is formed at the extended end of the piston rods. The latter point is engaged into corresponding form-adapted recess of the connection rods.

Description

Die Erfindung betrifft ein Kranfahrzeug mit einer auf seinem Unterwagen befestigbaren Grundplatte zur Ballastaufnahme und zwei vertikal an den in entgegengesetzter Richtung zu dem Ausleger auskragenden Teil des Oberwagens befestigten Hubmitteln mit ersten Lastaufnahmestellen, die in Aussparungen von an der Grundplatte angeordneten Verbindungsstangen einfahrbar sind und dort in angepasste Vertiefungen greifen. Erfindungsgemäß sind beide Hubmittel über die ersten Lastaufnahmestellen hinaus länger und an ihrem verlängerten Ende mit einer zweiten Lastaufnahmestelle versehen, die in entsprechende formangepasste Ausnehmungen der Verbindungsstangen eingreifen. Aufgrund dieser Ausgestaltung der Hubmittel können diese nicht nur Kräfte, sondern auch Momente aufnehmen. Durch diese zusätzliche Momentaufnahme ist das Ballastiersystem von der Lage des Schwenkpunktes des Gesamtballastes unabhängig. Somit kann der zur Verfügung stehende Platz unter Berücksichtigung der eingangs genannten Vorgabe optimal ausgenutzt werden. Es kann nämlich unabhängig von der Schwerpunktslage das jeweilig aufzusetzende Ballaststück eine vergleichsweise große Höhe aufweisen. Hierdurch kann der Raumbedarf des ausschwenkenden Oberwagens deutlich verringert werden.The invention relates to a crane vehicle with an attachable to his undercarriage base plate for Ballastaufnahme and two vertically mounted on the projecting in the opposite direction to the boom part of the superstructure lifting means with first load receiving points, which are retractable into recesses arranged on the base plate connecting rods and adapted there Recesses grip. According to the invention, both lifting means are longer beyond the first load receiving points and provided at their extended end with a second load receiving point, which engage in corresponding shape-adapted recesses of the connecting rods. Due to this design of the lifting means they can not only absorb forces, but also moments. Due to this additional snapshot, the ballast system is independent of the position of the pivot point of the entire ballast. Thus, the available space can be optimally utilized taking into account the aforementioned specification. Namely, regardless of the center of gravity, the respective ballast piece to be fitted can have a comparatively large height. As a result, the space requirement of the swiveling upper carriage can be significantly reduced.

Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den an den Hauptanspruch anschließenden Unteransprüchen.Preferred embodiments of the invention will become apparent from the subsequent claims to the main claim.

Vorzugsweise sind die Hubmittel hydraulische Zylinder mit ausfahrbaren die Lastaufnahmestellen tragenden Kolbenstangen. Die Lastaufnahmestellen sind vorteilhaft Halteteller. Anstelle von Haltetellern können aber auch andere Lastaufnahmestellen, wie beispielsweise Querbolzen vorgesehen sein.Preferably, the lifting means are hydraulic cylinders with extendable load bearing points carrying piston rods. The load receiving points are advantageous holding plate. Instead of holding plates but other load receiving points, such as transverse bolts may be provided.

Weiterhin können die zweiten Lastaufnahmemittel durch eine abschnittsweise Querschnittserweiterung im Endbereich der Kolbenstange gebildet sein.Furthermore, the second load-receiving means may be formed by a sectional cross-sectional widening in the end region of the piston rod.

Da die zweiten Lastaufnahmemittel im wesentlichen die Kräfte senkrecht zur Achse der Kolbenstange aufnehmen, reicht es hier aus, wenn der Querschnittsbereich im Endbereich der Kolbenstange erweitert ist. Hierdurch wird ein Bereich gebildet, der in eine entsprechend angepaßte Ausnehmung der Verbindungsstange greifen kann.Since the second load receiving means substantially absorb the forces perpendicular to the axis of the piston rod, it is sufficient here if the cross-sectional area is widened in the end region of the piston rod. As a result, an area is formed, which can engage in a correspondingly adapted recess of the connecting rod.

In den Verbindungsstangen sind Zentrierbereiche ausgebildet, über die die Lastaufnahmestellen in Richtung der Ausnehmungen der Verbindungsstange ausrichtbar sind. Dies sind meist konisch zulaufende Bereiche innerhalb der Verbindungsstangen, durch die die ersten und zweiten Lastaufnahmemittel an der Kolbenstange in die entsprechenden in der Verbindungsstange ausgebildeten Ausnehmungen eingeführt werden.In the connecting rods centering areas are formed, via which the load receiving points in the direction of the recesses of the connecting rod can be aligned. These are usually tapered portions within the connecting rods, through which the first and second load-receiving means on the piston rod are inserted into the corresponding recesses formed in the connecting rod.

Auf die Grundplatte zur Ballastaufnahme sind Ballaststücke nach Bedarf des aufzunehmenden Ballastgewichts auflegbar. Besonders vorteilhaft sind die aufgelegten Ballaststücke mit der Grundplatte und untereinander formschlüssig verbindbar. Hierdurch ist die Gesamtstabilität des Gesamtballastes erhöht.On the base plate for ballast ballast pieces are placed on demand of the male ballast weight. Particularly advantageous are the applied ballast pieces with the base plate and mutually positively connected. As a result, the overall stability of the total ballast is increased.

In den Ballaststücken sind Ausnehmungen als Einfahrbereich für die Kolbenstangen in die entsprechenden Verbindungsstangen der Grundplatte zur Ballastaufnahme ausgebildet.In the Ballaststücken recesses are designed as retraction area for the piston rods in the corresponding connecting rods of the base plate for ballast receiving.

In Figur 1 ist auf einem nicht näher dargestellten Podest des Unterwagens eines hier ebenfalls nicht dargestellten Kranfahrzeugs fluchtend ein Stapel von Ballaststücken 10, 12, 14 auf einer Grundplatte 16 abgelegt. Die Ballastplatten 10, 12 und 14 weisen eine derartige Form auf, daß sie formschlüssig ineinander greifen. Die Ballastplatte 10 ist so geformt, daß sie formschlüssig auf der Grundplatte 16 aufliegt.In FIG. 1 is on a non-illustrated pedestal of the undercarriage of a crane vehicle, also not shown here, a stack of ballast pieces 10, 12, 14 stored on a base plate 16. The ballast plates 10, 12 and 14 have a shape such that they engage positively in one another. The ballast plate 10 is shaped so that it rests positively on the base plate 16.

Die Ballaststücke 10, 12 und 14 weisen im Vergleich zu bekannten Ballaststücken eine größere Höhe auf. Hierdurch bedingt kann ein entsprechend hohes Gewicht bei Verkleinerung der Grundfläche der Ballaststücke erreicht werden. Aufgrund dieser verkleinerten Grundfläche der Ballaststücke kann der Platzbedarf, den der Oberwagen des Kranfahrzeuges beim Ausschwenken benötigt, verringert werden.The ballast pieces 10, 12 and 14 have compared to known Ballaststücken a greater height. As a result, a correspondingly high weight can be achieved with reduction of the base area of the ballast pieces. Due to this reduced footprint of Ballaststücke the space required by the superstructure of the crane vehicle when swinging can be reduced.

Der aus den Ballaststücken 10. 12 und 14 sowie der Grundplatte 16 bestehende Gesamtballast kann beispielsweise aus der DE 296 21 600 U1 in bekannter Art und Weise durch hydraulische Zylinder, die in dem hier nicht dargestellten Teil des Oberwagens angeordnet sind, aufgenommen werden.The ballast pieces 10, 12 and 14 and the base plate 16 existing total ballast can for example from the DE 296 21 600 U1 in a known manner by hydraulic cylinders, which are arranged in the part of the upper carriage, not shown here, are added.

In den Figuren 1 bis 3 sind hier die Zylinder 18 sowie die Kolbenstangen 20 dargestellt. Die Kolbenstangen 20 weisen erste Lastaufnahmestellen 22 in Form von Haltetellern auf. Diese Halteteller greifen in entsprechende Aussparungen 24 der Verbindungsstangen 26, die an der Grundplatte 16 befestigt sind.In the FIGS. 1 to 3 Here, the cylinder 18 and the piston rods 20 are shown. The piston rods 20 have first load receiving points 22 in the form of holding plates. These retaining plates engage in corresponding recesses 24 of the connecting rods 26, which are fastened to the base plate 16.

Wie in der DE 296 21 690 U1 beschrieben, können die Kolbenstangen 20 durch eine Schwenkbewegung des hier nicht näher dargestellten Oberwagens durch entsprechende örtliche Öffnungen 32 und 34 der Verbindungsstangen 26 in diese eingeschwenkt werden bis eine Position entsprechend der Figur 2 einnehmen. Anschließend werden die Kolbenstangen in Pfeilrichtung a (vergleich Figur 2) hochgezogen, so daß die in Halteteller 22 formangepaßte Ausnehmungen 24 in der Verbindungsstange einfahrbar sind.Like in the DE 296 21 690 U1 described, the piston rods 20 can be pivoted by a pivoting movement of the upper carriage not shown here by corresponding local openings 32 and 34 of the connecting rods 26 in this until a position corresponding to the FIG. 2 taking. Subsequently, the piston rods in the direction of arrow a (comparative FIG. 2 ), so that the form-fitting in retaining plate 22 recesses 24 are retractable in the connecting rod.

Diese eingefahrene Endposition ist in der Figur 3 gezeigt.This retracted end position is in the FIG. 3 shown.

Gemäß der vorliegenden Erfindung sind die Kolbenstangen 20 aber über den Halteteller 22 hinaus verlängert und weisen an ihren Enden eine zweite Lastaufnahmestelle 28 auf. Diese Lastaufnahmestelle besteht, wie in den Figuren 2 und 3 ersichtlich aus einer abschnittsweisen Querschnittserweiterung im Endbereich der Kolbenstange.According to the present invention, however, the piston rods 20 are extended beyond the retaining plate 22 and have at their ends a second load receiving point 28. This load receiving point consists, as in the Figures 2 and 3 apparent from a section-wise cross-sectional widening in the end region of the piston rod.

Dieser abschnittsweisen Querschnittserweiterung entspricht in der Verbindungsstange 26 ein formangepaßter Aufnahmebereich 30. Wie aus dem Vergleich der Figuren 2 und 3 zu sehen ist, fährt die zweite Lastaufnahmestelle 28 gleichzeitig wie die erste Lastaufnahmestelle 22, die in Form des Haltetellers ausgebildet ist, gleichzeitig in die entsprechende Ausnehmung 28, wenn die Kolbenstange in Pfeilrichtung a nach oben in die Kopplungsstellung gefahren wird.This section-wise cross-sectional widening corresponds in the connecting rod 26 to a shape-adapted receiving area 30. As can be seen from the comparison of FIGS Figures 2 and 3 can be seen, moves the second load receiving point 28 at the same time as the first load receiving point 22, which is in the form of the retaining plate, simultaneously in the corresponding recess 28 when the piston rod is moved in the direction of arrow a up in the coupling position.

Somit ist die Kolbenstange 20 eines jeden Ballasteierzylinders 18 so gestaltet, daß nicht nur Kräfte, sondern auch Momente aufgenommen werden. Hierdurch wird erreicht, daß das Ballastiersystem von der Lage des Schwerpunktes des Gesamtballastes unabhängig wird. Der auf der Baustelle zur Verfügung stehende Platz kann unter Berücksichtigung der entsprechend nunmehr möglichen Dimensionierung der Ballaststücke optimal genutzt werden.Thus, the piston rod 20 of each Ballasteierzylinders 18 is designed so that not only forces, but also moments are absorbed. This ensures that the ballast system is independent of the position of the center of gravity of the total ballast. The space available at the construction site can be used optimally taking into account the now possible dimensioning of the ballast pieces.

Unter Berücksichtigung der vorgenannten Darstellungen kann das Verfahren des Aufballastierens bei einem erfindungsgemäßen Kranfahrzeug wie folgt zusammengefaßt werden. Der Oberwagen wird auf die zum Aufballastieren vorgesehenen Drehstellung gebracht. Die Kolbenstangen 20 werden ausgefahren bis die Lastaufnahmestellen 22 und 28 in der Höhe der entsprechenden seitlichen Öffnungen 32 und 34 der Verbindungsstangen 20 liegen. Danach wird der Oberwagen gedreht, um eine Überlappung zwischen dem Halteteller 22 und der Ausnehmung 24 im Bereich der zweiten Lastaufnahmestelle 28 und der Ausnehmung 30 zu erhalten. Anschließend wird der Ballast durch Einfahren der Kolbenstange 20 abgehoben. Beim Einfahren der Kolbenstange läuft sowohl der Halteteller 22 wie auch die zweite Lastaufnahmestelle 28 an konisch ausgebildeten Zentrierflächen vorbei und erreicht die koppelnde Stellung (Figur 3).Taking into account the aforementioned illustrations, the method of ballasting in a crane vehicle according to the invention can be summarized as follows. The superstructure is brought to the rotational ballast intended for Aufballastieren. The piston rods 20 are extended until the load receiving points 22 and 28 lie in the height of the corresponding lateral openings 32 and 34 of the connecting rods 20. Thereafter, the superstructure is rotated to obtain an overlap between the holding plate 22 and the recess 24 in the region of the second load receiving point 28 and the recess 30. Subsequently, the ballast is lifted by retracting the piston rod 20. When retracting the piston rod, both the holding plate 22 and the second load receiving point 28 pass by conical centering surfaces and reach the coupling position (FIG. FIG. 3 ).
