Description

Die Erfindung betrifft einen Fahrzeugkran mit einem Unterwagen und einem drehbar auf diesem angeordneten Oberwagen mit einer Einrichtung zur Aufnahme von Ballast.The invention relates to a vehicle crane with an undercarriage and a rotatably mounted on this superstructure with a device for receiving ballast.

Während der Ballast während des Kraneinsatzes am hinteren Teil des Oberwagens angeordnet ist, wird er bei der Transportfahrt des Fahrzeugkrans von dem Oberwagen abgenommen und auf dem Unterwagen bzw. auf einem eigenen Transportfahrzeug abgelegt, um den Achslasten des Unterwagens gerecht zu werden. Es sind bereits eine Reihe von Einrichtungen zur Aufnahme des Ballastes bekannt. Diese weisen in der Regel rechtwinklig zu dem Oberwagen angeordnete Hydraulikzylinderanordnungen auf, die mit den jeweiligen Ballastpaketen bzw. Ballastpaletten verbindbar sind, um diese an den Oberwagen anzuheben.While the ballast is located at the rear of the superstructure during crane operation, it is removed during the transport journey of the vehicle crane from the superstructure and placed on the undercarriage or on its own transport vehicle to meet the axle loads of the undercarriage. There are already a number of facilities for receiving the ballast known. These generally have at right angles to the superstructure arranged hydraulic cylinder assemblies which are connectable to the respective ballast or ballast pallets to lift them to the superstructure.

Aufgabe der Erfindung ist es, einen Fahrzeugkran zu schaffen, bei dem die Einrichtung zur Aufnahme des Ballasts möglich platzsparend im Oberwagen des Fahrzeugkrans integriert werden kann.The object of the invention is to provide a vehicle crane, in which the means for receiving the ballast can be integrated to save space in the superstructure of the vehicle crane possible.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Demnach besteht die Einrichtung zur Aufnahme von Ballast aus mindestens drei vertikalen auf- und abbewegbaren Zugmitteln, die mit einer den Ballast tragenden Palette oder Grundplatte unterhalb des Gesamtschwerpunkts des Ballasts verbindbar sind, um die Palette bzw. Grundplatte an den Oberwagen heranzuziehen und mit ihm zu verbinden bzw. von diesem abzulassen. Mittels dieser Zugmittel kann der auf einer Palette bzw. Grundplatte abgelegte Ballast auch bei hohem Schwerpunkt sicher aufgenommen und auf- und abbewegt werden, wobei es hier von besonderem Vorteil ist, dass der Ballast auch vom Boden aufgenommen werden kann.According to the invention, this object is solved by the features of claim 1. Accordingly, the means for receiving ballast consists of at least three vertical up and down movable traction means which are connectable to a ballast carrying pallet or base plate below the overall center of gravity of the ballast, to use the pallet or base plate to the superstructure and to connect with him or leave this. By means of this traction means deposited on a pallet or base ballast can be safely picked up and down even at high center of gravity and it is particularly advantageous that the ballast can also be picked up from the ground here.

Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den sich an den Hauptanspruch anschließenden Unteransprüchen. So können am Oberwagen Laschen angeordnet sein, mit denen die Palette zur Befestigung am Oberwagen verbolzbar ist. Ist also der Ballast über die Ausgleichsschwingen an den Oberwagen hochgezogen, so liegen die Laschen in entsprechenden Ausnehmungen der Palette, die den Ballast trägt, und kann dort über geeignete Bolzen verbolzt werden.Preferred embodiments of the invention will become apparent from the subsequent claims to the main claim. So can be arranged on the superstructure lugs with which the pallet is bolted for attachment to the superstructure. So if the ballast is pulled over the balancing wings to the superstructure, the tabs are in corresponding recesses of the pallet, which carries the ballast, and can be bolted there over suitable bolts.

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung können die Zugmittel waagerecht in der Drehbühne des Oberwagens verlaufen und mehrfach geschert sein. Durch die mehrfache Scherung, beispielsweise eine zweifach Scherung, kann bei entsprechender Bewegung des Zugmittels in Längsrichtung des Oberwagens die doppelte Hubbewegung des Ballastes ausgeführt werden.According to a further preferred embodiment of the invention, the traction means can run horizontally in the revolving stage of the superstructure and be sheared several times. Due to the multiple shearing, for example, a double shear, the double stroke movement of the ballast can be performed with appropriate movement of the traction means in the longitudinal direction of the superstructure.

Als Zugmittel lassen sich erfindungsgemäß Ketten oder Seile einsetzen.As pulling means can be used according to the invention chains or ropes.

Bei Verwendung von Seilen können diese beispielsweise in acht Bandseile aufgegliedert sein, die wiederum aus fünf Einzelseilen bestehen. Dies hat den Vorteil, dass die Seilrollen sehr klein hinsichtlich ihres Durchmesserverhältnisses (D:d-Verhältnis) ausgeführt werden können, so dass die Umlenkrollen in der relativ niedrigen zur Verfügung stehenden Bauhöhe der Drehbühne des Oberwagens angeordnet sein können.When using ropes these can be broken down, for example, into eight band ropes, which in turn consist of five individual ropes. This has the advantage that the pulleys can be made very small in terms of their diameter ratio (D: d ratio), so that the pulleys can be arranged in the relatively low available height of the revolving stage of the superstructure.

In der Drehbühne des Oberwagens kann mindestens ein Hydraulikzylinder waagerecht oder leicht geneigt angeordnet sein, um durch Verlängerung bzw. Verkürzung die Zugmittel auf und ab zu bewegen. Durch diesen waagerechten oder leicht geneigten Einbau in der Drehbühne des Oberwagens wird sichergestellt, dass die Drehbühne nicht hoch baut.In the revolving stage of the superstructure, at least one hydraulic cylinder can be arranged horizontally or slightly inclined in order to move the traction means up and down by lengthening or shortening. This horizontal or slightly inclined installation in the revolving stage of the superstructure ensures that the revolving stage does not build up.

Vorzugsweise bilden jeweils ein Hydraulikzylinder mit den zugehörigen Seilen, die Umlenkrollen und die Ausgleichsschwingen eine Baueinheit, die zur Montage in die Drehbühne einschiebbar und mit dieser verbolzbar sind. Bei einer Ausführung mit vier Ausgleichsschwingen sind üblicherweise zwei Baueinheiten vorgesehen, die jeweils seitlich zwischen zwei Seitenwänden in der Drehbühne einbaubar sind.Preferably, in each case form a hydraulic cylinder with the associated ropes, the pulleys and the balance rockers a structural unit, which can be inserted for mounting in the revolving stage and with this verbolzbar. In an embodiment with four balancing wings usually two units are provided, which are laterally installed between two side walls in the revolving stage.

In Figur 2 ist eine Drehbühne 10 eines Fahrzeugkrans dargestellt, bei der ein Drehkranz 12, ein Wippzylinder 14 für den hier nicht näher dargestellten Ausleger und eine Hubseilwinde 16 in üblicher Art und Weise ausgebildet ist. In der Drehbühne 10 ist eine Einrichtung 18 zur Aufnahme von Ballast integriert. Diese besteht aus zwei gleich aufgebauten Einheiten, von denen in der Figur 1 nur eine Einheit gezeigt ist. Diese Einheit 18 ist als Baueinheit ausgebildet und kann als Ganzes zwischen zwei Seitenwänden 20 (nur eine ist hier gezeigt) der Drehbühne 10 eingebaut sein. Eine Baueinheit 18 besteht aus einem Hydraulikzylinder 22, der in der hier dargestellten Ausführungsvariante waagerecht in die Drehbühne eingebaut ist. Weiterhin sind hier waagerecht verlaufende Seile 24 zweifach zwischen Rollen 32 eingeschert.FIG. 2 shows a revolving platform 10 of a vehicle crane, in which a turntable 12, a rocking cylinder 14 for the boom, which is not shown here, and a hoist winch 16 are formed in the usual manner. In the turntable 10, a device 18 for receiving ballast is integrated. This consists of two identically constructed units, of which only one unit shown in FIG is. This unit 18 is designed as a structural unit and can be installed as a whole between two side walls 20 (only one is shown here) of the revolving platform 10. An assembly 18 consists of a hydraulic cylinder 22, which is installed horizontally in the revolving stage shown in the embodiment shown here. Furthermore, here horizontally extending ropes 24 are reeved twice between rollers 32.

An den Seilen sind, wie in Figur 2 dargestellt, Ausgleichsschwingen 26 angeordnet, wobei hier zwei Ausgleichsschwingen gezeigt sind. Ingesamt ergeben sich also bei Verdoppelung der entsprechenden Ballastaufnahmeeinrichtungen 18 vier Ausgleichsschwingen 26.As shown in FIG. 2, balancing wings 26 are arranged on the ropes, two balancing wings being shown here. In total, therefore, when doubling the corresponding ballast receiving devices 18 four balancing wings 26th

Die Ausgleichsschwingen 26 können über Verkürzung bzw. Verlängerung der Seile auf und ab bewegt werden. In der herabgelassenen Stellung sind sie in Figur 1 gezeigt, während sie in der Figur 2 in der hochgezogenen Stellung gezeigt sind. Die Verkürzung bzw. Verlängerung der Seile erfolgt über den Hydraulikzylinder 22. In Figur 1 ist der Hydraulikzylinder 22 vollständig eingefahren, so dass die Seile 24 und damit die an diesen angeordneten Ausgleichsschwingen vollständig herabgelassen sind. In dieser Stellung können sie mit einer Palette 27 verbolzt werden, die jeweils auf ihren Seiten Ballastplatten 27 aufnimmt. Durch Ausfahren des Hydraulikzylinders 22 werden die Seile 24 hochgezogen, so dass die Ausgleichsschwingen 26 in die Position gemäß Figur 2 hochgezogen werden. Hierdurch gelangt die Palette 27 in eine Position unmittelbar unterhalb der Drehbühne, in der Befestigungslaschen 30 in entsprechende Ausnehmungen der Palette eintauchen und dort mit der Palette verbolzt werden können. In dieser Position ist der Ballast betriebsfertig mit dem Oberwagen verbunden. Das Ablassen des Ballastes erfolgt in umgekehrter Reihenfolge.The balancing wings 26 can be moved up and down by shortening or lengthening the ropes. In the lowered position they are shown in Figure 1, while in Figure 2 they are shown in the raised position. The shortening or lengthening of the cables takes place via the hydraulic cylinder 22. In FIG. 1, the hydraulic cylinder 22 is completely retracted, so that the cables 24 and thus the compensating rockers arranged on them are lowered completely. In this position, they can be bolted to a pallet 27, each receiving ballast plates 27 on its sides. By extending the hydraulic cylinder 22, the ropes 24 are pulled up so that the balancing wings 26 are pulled up into the position shown in FIG. As a result, the pallet 27 comes into a position immediately below the revolving stage, in the attachment tabs 30 dive into corresponding recesses of the range and can be bolted there with the pallet. In this position, the ballast is ready for use connected to the superstructure. The ballast is discharged in reverse order.

In den Figuren 3 und 4 ist der Aufbau der Ballastaufnahmeeinrichtungen 18 in weiterem Detail dargestellt. Insbesondere erkennt man aus der Schnittzeichnung gemäß der Figur 3 zunächst eine Seilführungswanne 40 für die unteren Seile 24 sowie aus der Figur 4 eine Seilführungswanne 42 zur Führung der oberen Seile. In den Figuren 3 und 4 ist der Hydraulikzylinder 22 eingefahren, so dass die Seile 24 in dieser Position ausgezogen sind und die Ballastplatte 27 nach unten bewegt ist. Durch entsprechendes Ausfahren des Hydraulikzylinders 22 werden die Seile 24 um die Rollen 32 umgelenkt und entlang der Bahnen 40 und 42 bewegt. Um die vollständige Bewegung des Hydraulikzylinders 22 mitmachen zu können, ist die Seilführungswanne 42 für die oberen Seile 24 ausziehbar.In Figures 3 and 4, the structure of the ballast receiving devices 18 is shown in more detail. In particular, it can be seen from the sectional drawing of Figure 3, first a cable guide tray 40 for the lower ropes 24 and 4 a cable guide tray 42 for guiding the upper ropes. In Figures 3 and 4, the hydraulic cylinder 22 is retracted, so that the ropes 24 are pulled out in this position and the ballast plate 27 is moved downward. By corresponding extension of the hydraulic cylinder 22, the ropes 24 are deflected around the rollers 32 and moved along the tracks 40 and 42. To be able to join in the complete movement of the hydraulic cylinder 22, the cable guide trough 42 for the upper cables 24 is extendable.

Aufgrund der vorhandenen vier Anschlagpunkte kann der Ballast auch bei hoch liegendem Schwerpunkt des Ballastes sicher aufgenommen werden.Due to the existing four attachment points, the ballast can be safely absorbed even when the center of gravity of the ballast is high.

Vorteilhaft kann bei der hier vorgeschlagenen Ballastierung der Ballast direkt vom Boden aufgenommen werden, so dass das Aufsetzen der Ballastklötze 28 in einer niedrigen Höhe erfolgen kann.Advantageously, in the case of the ballast proposed here, the ballast can be picked up directly from the ground, so that the placing of the ballast blocks 28 can take place at a low height.

Ist ein entsprechend tragfähiges Transportfahrzeug vorhanden, kann der Ballast ohne weiteren Hilfskran direkt auf das Transportfahrzeug abgesetzt werden. An einer neuen Einsatzstelle kann der Ballast dann wieder direkt vom Transportfahrzeug aufgenommen werden. Dies ist insbesondere bei der Montage von Windkraftanlagen von Vorteil.If a suitably viable transport vehicle is available, the ballast can be placed directly on the transport vehicle without any additional auxiliary crane. At a new job site, the ballast can then be picked up again directly from the transport vehicle. This is particularly advantageous when installing wind turbines.

Die Seile 24 sind insgesamt in acht Bandseile aufgegliedert, die jeweils wiederum aus fünf Einzelseilen bestehen. Dies hat den Vorteil, dass die Seilrollen 32 sehr klein hinsichtlich ihres Durchmesserverhältnisses ausgeführt werden können, so dass diese Seilrollen bzw. Umlenkrollen 32 in der relativ geringen zur Verfügung stehenden Bauhöhe untergebracht werden können.The ropes 24 are broken down into a total of eight band ropes, each of which in turn consists of five individual ropes. This has the advantage that the pulleys 32 can be made very small in terms of their diameter ratio, so that these pulleys or pulleys 32 can be accommodated in the relatively low available height.

Beim Hochziehen des Ballastes 27 an die Drehbühne 10 zentriert sich der Ballast selbsttätig, indem der Ballast unter den vier Anhängepunkten auspendelt.When pulling up the ballast 27 to the revolving platform 10, the ballast is self-centering by the ballast under the four attachment points auspendelt.
