Description

Kran, insbesondere mobiler Kran mit schmaler Spur und erweiterter Stützbasis Crane, in particular a mobile crane with a narrow track and extended support base

Die Erfindung betrifft einen Kran gemäß dem Oberbegriff der Ansprüche 1 und 10.The invention relates to a crane according to the preamble of claims 1 and 10.

Krane mit gummibereiftem Fahrwerk sind in der Regel mit Stützen ausgestattet (siehe Figur 9). Das Heben von Lasten ist in der Regel nur möglich, wenn der Kran auf den Stützen steht. Krane mit Raupenfahrwerk haben meist keine Stützen, sondern heben Lasten auf den Raupen stehend und können meist auch mit der Last verfahren. Um eine größere Stützbasis zu erhalten, können auch Raupenkrane zusätzlich mit Stützen ausgestattet werden. Figur 10 zeigt den Unterwagen des Demag CC/PC 3800. Die wichtigsten Komponenten sind in Figur 11 schematisch dargestellt, wobei die Fahrtrichtung durch den Pfeil 1 angedeutet ist. Von der Drehmitte 2 reichen vier Arme 4 zu den Raupen 3. An den Außenseiten der Raupen sind vier Stützen 5 befestigt. Ein solcher Kran kann sowohl auf den Raupen stehend, als auch auf den Stützen stehend betrieben werden. Diese Anordnung hat im Betrieb auf Stützen einen direkten Kraftverlauf, was erstrebenswert ist. Allerdings müssen die Kräfte und Momente durch die Raupen 11 durchgeleitet werden. Am Ende der Raupen befinden sich Umlenkräder, Getriebe und Kettenspanneinrϊchtungen; Dadurch ist es schwer, an dieser Stelle die Kräfte durchzuleiten. Figur 12 zeigt einen Unterwagen ähnlich Figur 11. Hier sind die Raupen über ein Mittelstück 6 miteinander verbunden. Dieses Mittelstück ist die übliche Konstruktion für einen Raupenkran ohne Stützen. Ih der Mitte des Raupenträgers ist in der Regel ausreichend Platz. Daher ist die Montage und die Verbolzung der Komponenten relativ unproblematisch.Cranes with rubber-tired chassis are usually equipped with supports (see Figure 9). The lifting of loads is usually only possible when the crane stands on the supports. Cranes with crawler tracks usually have no supports, but lift loads on the caterpillars and can usually also move with the load. In order to obtain a larger support base, caterpillar cranes can also be equipped with supports. FIG. 10 shows the undercarriage of the Demag CC / PC 3800. The most important components are shown schematically in FIG. 11, the direction of travel being indicated by the arrow 1. Four arms 4 extend from the turning center 2 to the caterpillars 3. Four supports 5 are fastened to the outsides of the caterpillars. Such a crane can be operated standing on the caterpillars as well as standing on the supports. This arrangement has a direct force curve in operation on supports, which is desirable. However, the forces and moments must be passed through the tracks 11. At the end of the caterpillars there are guide wheels, gearboxes and chain tensioners ; This makes it difficult to pass through the forces at this point. FIG. 12 shows an undercarriage similar to FIG. 11. Here, the caterpillars are connected to one another via a middle piece 6. This center piece is the usual construction for a crawler crane without supports. In the middle of the caterpillar carrier is usually enough space. Therefore, the assembly and the bolting of the components is relatively unproblematic.

Im Stützenbetrieb sind die Kräfte in den Stützen in der Regel nicht gleichmäßig verteilt. Dadurch entsteht ein Torsionsmoment im Mittelstück 6 und auch in den Raupen 3. In Figur 13 sind neben dem Mittelstück 6 auch die Stützen 7 an der Raupenmitte angebracht. Dadurch werden die Raupen 3 entlastet.In column operation, the forces in the columns are usually not evenly distributed. This results in a torsional moment in the middle piece 6 and also in the beads 3. In Figure 13, in addition to the center piece 6 and the supports 7 are attached to the caterpillar center. As a result, the caterpillars 3 are relieved.

Der Erfindung liegt die Aufgabe zugrunde, einen Kran, insbesondere einen mobilen Kran auf schmalbauendem Raupenfahrwerk derart mit Stützen auszustatten, dass eine vergrößerte Stützbasis erreicht wird.The invention has for its object to equip a crane, in particular a mobile crane on narrow-building crawler undercarriage in such a way with supports that an enlarged support base is achieved.

Gelöst wird diese Aufgabe nach Anspruch 1 durch einen Kran, insbesondere einen mobilen Kran, bestehend aus einem Unterwagen, einem Oberwagen und einem darauf angeordneten Ausleger, wobei der Oberwagen mit dem Unterwagen über eine Drehverbindung verbunden ist und wobei mehrere Stützen am Kran vorgesehen sind, die ≥ur Erhöhung der Stützbasis dienen, der dadurch gekennzeichnet ist, dass der Unterwagen aus einem Mittelstück und an zwei Seiten des Mittelstückes parallel zueinander angeordneten Raupenfahrwerken besteht, dass vier Stützen vorgesehen sind, die mit dem Unterwagen verbunden sind, wobei deren Ausrichtung derart fixiert ist, dass sie jeweils einen Winkel von 90° miteinander einschließen, wobei zwei der Stützen in Längsrichtung des Unterwagens und zwei quer dazu ausgerichtet sind.This object is achieved according to claim 1 by a crane, in particular a mobile crane, consisting of an undercarriage, a superstructure and a boom arranged thereon, wherein the superstructure connected to the undercarriage via a rotary joint and wherein a plurality of supports are provided on the crane, which serve ≥ur increase the support base, which is characterized in that the undercarriage consists of a central piece and on two sides of the central piece of parallel crawler tracks that four supports are provided with the Undercarriage are connected, with their orientation is fixed so that they each enclose an angle of 90 ° with each other, wherein two of the supports in the longitudinal direction of the undercarriage and two are aligned transversely thereto.

Durch die Anordnung der Stützen in Längsrichtung bzw. quer zum Unterwagen ergibt sich ein direkter Kraftfluss. Dadurch treten keine vermeidbaren Momente auf. Die auftretenden Kräfte und Spannungen sind kleiner. Weniger Material wird benötigt. Gewicht und Kosten werden reduziert. Außerdem ist die Verbindungsstelle von Stützen an das Fahrwerk stets rechtwinklig. Dies ist im Allgemeinen leichter und schneller zu montieren als eine schräge Verbindungsstelle. Auch ist der Platzbedarf für die Verbindung geringer.The arrangement of the supports in the longitudinal direction or transversely to the undercarriage results in a direct power flow. As a result, no avoidable moments occur. The occurring forces and stresses are smaller. Less material is needed. Weight and costs are reduced. In addition, the connection point of supports to the chassis is always rectangular. This is generally easier and quicker to install than a sloping joint. Also, the space required for the connection is lower.

Vorzugsweise sind die Stützen parallel zu den Raupen und senkrecht zu den Raupen angeordnet und schneiden sich in der Drehmitte. Die konkrete Ausgestaltung kann davon abweichen. Es gilt jedoch, dass die Enden der Stützen quer zur Fahrtrichtung außerhalb der Spur liegen und dass die Stützen längs der Fahrtrichtung innerhalb der Spur liegen.Preferably, the supports are arranged parallel to the caterpillars and perpendicular to the caterpillars and intersect at the center of rotation. The concrete design may differ. However, it is true that the ends of the supports are transverse to the direction of travel outside the track and that the supports lie along the direction of travel within the track.

Die Anbindung der Stützen an den Unterwagen kann nach einer Ausführung dadurch erfolgen, dass von den quer ausgerichteten Stützen zumindest eine direkt am Raupenfahrwerk angebracht ist. 'The connection of the supports to the undercarriage can be carried out according to an embodiment in that of the transversely oriented supports at least one is attached directly to the crawler chassis. '

Es kann aber auch eine der seitlichen Stützen mit ihrer Unterseite mit dem zugewandten Raupenfahrwerk verbunden sein, während deren Oberseite am Mittelstück befestigt ist.But it may also be one of the lateral supports with its underside connected to the facing crawler undercarriage, while the upper side is fixed to the center piece.

Die Stützen in Längsrichtung können direkt am Mittelstück befestigt werden, oder an der zum Mittelstück weisenden Seite des Raupenfahrwerks, oder an Mittelstück und Raupenfahrwerk befestigt werden.The supports in the longitudinal direction can be attached directly to the center piece, or attached to the centerpiece facing side of the crawler chassis, or to center and crawler chassis.

Nach einer weiteren Ausgestaltung können die Stützen teleskopierbar ausgestaltet, nach oben oder seitlich klappbar sein.According to a further embodiment, the supports can be designed to be telescopic, can be folded upwards or laterally.

Am Kopf der Stützen sind ausfahrbare, den Kontakt zur Stützfläche herstellende Stüt∑zylinder angeordnet. Eine besondere Ausgestaltung, die sowohl für stationäre Krane als auch für mobile Krane vorteilhaft ist besteht darin, dass zumindest eine der Stützen als auf zwei Punkten stehende Kippkante ausgebildet ist.At the top of the supports extendable, the contact to the support surface producing StütΣzylinder are arranged. A particular embodiment, which is advantageous both for stationary cranes and for mobile cranes, is that at least one of the supports is designed as a tilting edge that is located on two points.

Dabei kann am Kopf der Stütze ein Querträger befestigt sein und im Abstand voneinander sind am Querträger zwei Stützzylinder vorgesehen.In this case, a cross member may be attached to the head of the support and at a distance from each other two support cylinders are provided on the cross member.

Die Stützzylinder können beispielsweise hydraulisch oder mittels eines Spindeltriebes ausfahrbar sein.The support cylinders may for example be hydraulically or by means of a spindle drive extendable.

Schließlich kann mittig zwischen den am Querträger angeordneten Stützzylindern ein weiterer Stützzylinder am Kopf der Stütze angeordnet sein.Finally, a further support cylinder may be arranged at the head of the support centrally between the support cylinders arranged on the cross member.

Die Stützzylinder können - nach einer weiteren Ausgestaltung - an ihren freien Enden über Kugelgelenke mit einer Stützmatte verbunden sein und es ist möglich, dass einer der am Querträger angeordneten Stützzylinder um seine Längsachse drehbar in diesem gelagert ist, um eventuelle Verzwängungskräfte auszuschließen.The support cylinders can - according to another embodiment - be connected at their free ends via ball joints with a support mat and it is possible that one of the cross member arranged support cylinder is rotatably mounted about its longitudinal axis in this, in order to exclude any Verzwängungskräfte.

Die Erfindung soll nachfolgend an den Zeichnungen näher erläutert werden.The invention will be explained in more detail below with reference to the drawings.

Gemäß der Erfindung (Figur 1) besitzt der Kran 4 Stützen. In Fahrtrichtung gesehen zeigt eine Stütze 8 nach vorne und liegt innerhalb der Spur. Eine Stütze 9 zeigt nach hinten und liegt innerhalb der Spur. Eine Stütze 10 zeigt nach links und liegt außerhalb der Spur. Eine Stütze 11 zeigt nach rechts und liegt außerhalb der Spur. Bei dieser Anordnung werden alle Stützen als reine Biegeträger beansprucht. Auch das Mittelstück 14 und die Raupen 11 werden nicht auf Torsion beansprucht. Der Anschluss der Stützen 17 - 20 an die Raupen 11 bzw. an das Mittelstück 14 geschehen jeweils senkrecht und an Stellen mit ausreichend Platz.According to the invention (Figure 1), the crane has 4 supports. Seen in the direction of travel shows a support 8 forward and is within the track. A support 9 points to the rear and lies within the track. A support 10 points to the left and is out of the track. A Prop 11 points to the right and is out of the track. In this arrangement, all columns are claimed as pure bending beam. Also, the centerpiece 14 and the caterpillars 11 are not subjected to torsion. The connection of the supports 17-20 to the caterpillars 11 and to the middle piece 14 takes place in each case vertically and in places with sufficient space.

Figur 2 zeigt einen erfindungsgemäßen Kran von hinten gesehen. Der Oberwagen 12 mit Ausleger 13 und Gegengewicht 14 ist über eine Drehverbindung 15 mit dem Mittelstück 6 drehbar verbunden. Wie in Figur 2 zu sehen ist, können bei dieser Anordnung die Stützen relativ lang werden, wodurch große Momente in den Stützen auftreten. Da die linke Stütze 10 durch die Raupe 3 hindurchgeführt werden, ist die Höhe der Stütze 10 durch die Höhe der Raupen begrenzt.Figure 2 shows a crane according to the invention seen from behind. The superstructure 12 with boom 13 and counterweight 14 is rotatably connected via a rotary joint 15 with the center piece 6. As can be seen in Figure 2, in this arrangement, the posts can become relatively long, causing large moments to occur in the posts. Since the left support 10 are passed through the bead 3, the height of the support 10 is limited by the height of the beads.

Die Art der Anbindung der rechten Stütze 11 hebt diese Beschränkung auf. Die Unterseite der Stützen 11 wird mit der rechten Raupe verbunden. Die Oberseite wird an das Mittelstück 6 angeschlagen. Weiterhin ist es möglich, die Stütze ausschließlich am Mittelstück 3 zu befestigen. In diesem Fall müssen keine Modifikationen an den Raupen vorgenommen werden. Falls die Stützen 10,11 mit dem Mittelstück verbunden werden, muss diese Verbindung zwischen der Drehverbindung und der Verbindung zu den Raupen liegen. Die hintere Stütze 9 ist nur am Mittelstück befestigt. Um das Moment in der Stütze zu reduzieren, kann sie wie die vordere Stütze' 8 sowohl am Mittelstück, als auch an den Raupen befestigt werden. Selbstverständlich ist es auch möglich, die Stützen 8,9 nur an den Raupen zu befestigen.The type of connection of the right support 11 removes this restriction. The underside of the supports 11 is connected to the right bead. The top is struck against the center piece 6. Furthermore, it is possible to attach the support exclusively on the center piece 3. In this case, no modifications to the beads must be made. If the supports 10,11 are connected to the center piece, this connection must be between the rotary joint and the connection to the beads. The rear support 9 is attached only to the center piece. To reduce the moment in the support, it can be attached to both the center piece and the caterpillars like the front support ' 8. Of course, it is also possible to attach the supports 8.9 only to the caterpillars.

Figur 3 zeigt eine weitere vorteilhafte Ausführungsform. Eine Stütze 16 wird derart gestaltet, so dass eine Kippkante an der Stütze entsteht. Anhand der Figuren 4 und 5 wird der Vorteil erläutert. In Figur 4 sind schematisch 4 Stützen 17 dargestellt, die zentrisch zur Drehmitte 2 angeordnet sind. Die Verbindungslinie 18 zwischen den Enden je zwei benachbarter Stützen wird als Kippkante 18 bezeichnet. Sollte der Kran seine Standsicherheit verlieren (Unfall), würde er über diese Kante 18 kippen. Wird eine Stütze 16 (Figuren 4 und 5) so ausgeführt, dass sie auf 2 Punkten steht, entsteht eine Kippkante 19, die einen größeren Abstand zur Drehmitte aufweist als die herkömmlichen Kippkanten 18. Dadurch ergibt sich eiii erhöhtes Lastmoment, wenn der Ausleger über dieser Stütze steht. Dieses erhöhte Lastmoment kann genutzt werden, um besonders schwere Hübe durchzuführen oder um besonders lange Ausleger vom Boden aufzurichten.FIG. 3 shows a further advantageous embodiment. A support 16 is designed such that a tilting edge is formed on the support. The advantage will be explained with reference to FIGS. 4 and 5. In Figure 4 4 supports 17 are shown schematically, which are arranged centrally to the center of rotation 2. The connecting line 18 between the ends of each two adjacent supports is referred to as tilting edge 18. Should the crane lose its stability (accident), it would tip over this edge 18. If a support 16 (FIGS. 4 and 5) is designed so that it is at two points, a tilting edge 19 is formed, which has a greater distance from the center of rotation than the conventional tilting edges 18. This results in an increased load moment eiii when the boom above this Prop stands. This increased load torque can be used to perform particularly heavy strokes or to erect extra long boom from the ground.

Anhand der Figuren 6, 7 und 8 werden mögliche Ausführungsformen derartiger Stützen erläutert. Figur 8 zeigt eine typische herkömmliche Stütze. Am Ende des Stützträgers 20 ist ein Hydraulikzylinder 21 angebracht, der über ein Kugelgelenk 22 mit einem Stützteller 23 verbunden ist. Durch das Kugelgelenk wird sichergestellt,' dass kleine Bodenunebenheiten ausgeglichen werden. Eine erfindungsgemäße Stütze muss an deren Ende eine Kippkante aufweisen. Eine mögliche Ausfertigung (Figur 7) besteht aus einer Stütze mit einem Stützzylinder 21 und zwei zusätzlichen Stützen 24, die seitlich im vorderen Bereich des Stützträgers 20 an einem Querträger 25 angebracht werden, Im normalen Kranbetrieb wird der mittlere Stützzylinder 21 verwendet. Um die zusätzliche Stützkante zu aktivieren werden die seitlichen Stützen 24 ausgefahren. Dies kann hydraulisch oder mittels Spindelantrieb geschehen. Auch klappbare oder steckbare Stützen sind möglich. Eine andere Ausführungsform zeigt Figur 8. Im vorderen Bereich sind zwei Stützzylinder 26,27 an einem Querbalken 29 angebracht. Über Kugelgelenke sind sie mit einer Stützmatte 28 verbunden. Um Verzwängungskräfte-auszuschließen ist einer der Zylinder 27 drehbar im Querbalken 29 gelagert. Bei aktivierter zusätzlicher Kippkante wird das Hydrauliköl in den Zylindern eingesperrt. Die Anordnung ist dann starr, Im normalen Kranbetrieb (Standard-Stützbasis) werden die Zylinder hydraulisch gleichgeschaltet, so dass Öl ungehindert von einem Zylinder in den anderen fließen kann.. Damit ist die Stüt∑matte um einen Punkt zwischen den Zylindern drehbar. Diese Möglichkeit, zwischen normalem Betrieb und Betrieb mit erweiterter Kippkante umschalten zu können, ist nicht zwingend notwendig. Dadurch wird allerdings gewährleistet, dass die Bodendruckverteilung unter der Stützmatte (28) gleichmäßig ist. With reference to Figures 6, 7 and 8 possible embodiments of such supports are explained. Figure 8 shows a typical conventional support. At the end of the support beam 20 is a hydraulic cylinder 21 is attached, which is connected via a ball joint 22 with a support plate 23. The ball joint ensures ' that small uneven floors are compensated. A support according to the invention must have a tilting edge at its end. A possible embodiment (Figure 7) consists of a support with a support cylinder 21 and two additional supports 24 which are mounted laterally in the front region of the support beam 20 on a cross member 25. In normal crane operation, the middle support cylinder 21 is used. To activate the additional supporting edge, the lateral supports 24 are extended. This can be done hydraulically or by spindle drive. Also foldable or plug-in supports are possible. Another embodiment is shown in FIG. 8. In the front area, two support cylinders 26, 27 are attached to a transverse bar 29. About ball joints they are connected to a support mat 28. To exclude Verzwängungskräfte one of the cylinder 27 is rotatably mounted in the crossbar 29. When the additional tilting edge is activated, the hydraulic oil is locked in the cylinders. The arrangement is then rigid. In normal crane operation (standard support base), the cylinders are hydraulically balanced so that oil can flow freely from one cylinder to the other. , Thus, the support mat is rotatable about a point between the cylinders. This possibility of being able to switch between normal operation and operation with extended tilting edge is not absolutely necessary. This ensures, however, that the ground pressure distribution under the support mat (28) is uniform.
