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 the crane operation, it is removed during the transport journey of the vehicle crane from the superstructure and stored 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.
Aus der
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.

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
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.
