Description

Die Erfindung betrifft einen Betonverteilermast für Transportbeton, bestehend aus dem Grundrahmen, dem Drehturm mit Drehkranzverbindung, dem Drehschemel, dem Mastpaket, bestehend aus mehreren Mast-Teilstücken, verbunden durch Knickgelenke, der Betonrohrleitung, mit mindestens einer Trennstelle im Verteilermast, wodurch der gesamte Verteilermast in mindestens zwei Sektionen teilbar und daher auf mindestens zwei Kraft­fahrzeugen transportierbar wird.
Für Betonverteilermaste der genannten Art ist es erforderlich, eine möglichst große Gesamtlänge, d.h. Reichhöhe, zu erzielen, um die Ein­satzmöglichkeiten zu vergrößern. Dabei soll das Gesamttransportgewicht gering gehalten werden.
Es sind Betonverteilermaste bekannt, die teilbar sind. Dazu wird min­destens ein Mast-Teilstück teilbar und mit einer Schnellverbindungs­stelle ausgerüstet. Das andere Mastpaket ist für sich auf einem Spezial­fahrzeug transportierbar. An der Einsatzstelle wird das vordere Mast­paket mittels einer separaten Hilfseinrichtung, z.B. einem Autokran, an das hintere Mastpaket, bzw. das Grund-Mast-Teilstück, montiert.The invention relates to a concrete placing boom for ready-mixed concrete, consisting of the base frame, the turret with slewing ring connection, the turntable, the mast package, consisting of several mast sections, connected by articulated joints, the concrete pipeline, with at least one separation point in the placing boom, whereby the entire placing boom in at least two sections can be divided and can therefore be transported on at least two motor vehicles.
For concrete placing booms of the type mentioned, it is necessary to achieve the greatest possible overall length, ie reach height, in order to increase the possible uses. The total transport weight should be kept low.
Concrete placing booms are known which are divisible. For this, at least one mast section is separable and equipped with a quick connection point. The other mast package can be transported on a special vehicle. At the point of use, the front mast package is mounted on the rear mast package or the basic mast section using a separate auxiliary device, such as a mobile crane.

Der Erfindung liegt die Aufgabe zugrunde, ohne eine separate Hilfsein­richtung, wie z.B. einem Autokran, auszukommen.The invention has for its object without a separate auxiliary device, such as. a truck crane to get by.

Die Lösung der gestellten Aufgabe erfolgt mittels der Ausgestaltung des Betonverteilermastes und der Zusatzeinrichtung gemäß dem Kennzeichen des Hauptanspruchs.The task is solved by means of the design of the concrete placing boom and the additional device according to the characterizing part of the main claim.

Vorteilhafte Ausgestaltungen der Erfindung werden erzielt durch die kennzeichnenden Merkmale der Unteransprüche.Advantageous embodiments of the invention are achieved by the characterizing features of the subclaims.

Die erfindungsgemäß Ausgestaltung des Betonverteilermastes in Kombi­nation mit dem drehbaren Tragtisch auf dem zweiten Kraftfahrzeug, dem Masttransporter, hat den Vorteil der Gewichts-, bzw. Hilfseinrichtungs­minimierung. Es kann auf jede separate Hilfseinrichtung verzichtet werden. Die beiden Kraftfahrzeuge, als Serienfahrzeuge, werden durch die Mastpakete für die maximale Reichhöhe voll ausgelastet.The design according to the invention of the concrete placing boom in combination with the rotatable support table on the second motor vehicle, the mast transporter, has the advantage of minimizing the weight or auxiliary equipment. Each separate auxiliary device can be dispensed with. The two vehicles, as series vehicles, are fully utilized by the mast packages for the maximum reach.

Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt. Es zeigen:

  • Fig. 1- die beiden Kraftfahrzeuge in Montagestellung mit der Trennstelle im Verteilermast in einem Auslegearm
  • Fig. 2- die beiden Kraftfahrzeuge in Montagestellung mit der Trennstelle zwischen Grundrahmen und Drehturm
Embodiments of the invention are shown in the drawings. Show it:
  • Fig. 1- the two motor vehicles in the assembly position with the separation point in the boom in a boom
  • Fig. 2- the two motor vehicles in the assembly position with the separation point between the base frame and turret

Auf dem Träger-Kraftfahrzeug 1 nach Fig. 1 ist der Auslegearm 2 mittels Knickgelenk in bekannter Weise am Drehtrum 3 angeordnet. Der Auslegearm ist am freien Ende ausgebildet für das Einfahren und Arretieren des rest­lichen Mast-Teilstücke vom Hilfskraftfahrzeug 4. Auf dem Hilfskraftfahrzeug 4 sind die restlichen Mast-Teilstücke so auf dem Tragtisch 5 lösbar ge­lagert, daß das obere Mast-Teilstück 6 mit seinem freien Ende oben liegt. Dieses obere Mast-Teilstück 6 enthält im Inneren ein teleskopierbares Ver­längerungsstück 7, das in den Auslegearm 2 eingefahren wird. Nach dem Ein­fahren werden Auslegearm 2 und das Mast-Teilstück 6 in bekannter Weise kraft- und formschlüssig verbunden und arretiert. Nach dem Lösen der Rest-Mast-­Teilstücke vom Tragtisch 5 und dem Anschluß aller Hydraulikleitungen ein­schließlich der Betonförderleitung, kann der Betonverteilermast in Arbeits­stellung gefahren werden.On the carrier motor vehicle 1 according to FIG. 1, the extension arm 2 is arranged on the rotary run 3 in a known manner by means of an articulated joint. The extension arm is designed at the free end for retracting and locking the remaining mast sections from the auxiliary vehicle 4. On the auxiliary vehicle 4, the remaining mast sections are detachably mounted on the support table 5 such that the upper mast section 6 with its free end lies above. This upper mast section 6 contains a telescopic extension piece 7, which is inserted into the extension arm 2. After retracting, extension arm 2 and mast section 6 are connected and locked in a known manner in a non-positive and positive manner. After loosening the remaining mast sections from the support table 5 and connecting all hydraulic lines including the concrete delivery line, the concrete placing boom can be moved into the working position.

Um das Einfädeln des Verlängerungsstückes 7 in den Auslegearm 2 in der waagerechten Ebene zu ermöglichen, ist der Tragtisch 5 drehbar. Die vom Träger-Kraftfahrzeug 1 und vom Hilfskraftfahrzeug 4 zu befahrende Geländefläche ist in der Regel nicht vollkommen eben, d.h. sie befinden sich für den Ankuppelvorgang auf unterschiedlichem Niveau. Deshalb wird in vorteilhafter Weise der Tragtisch 5 hydraulisch hebbar (senk­recht verfahrbar) ausgestattet.In order to enable the extension piece 7 to be threaded into the extension arm 2 in the horizontal plane, the support table 5 can be rotated. The area to be traveled by the carrier motor vehicle 1 and the auxiliary motor vehicle 4 is generally not completely flat, i.e. they are at different levels for the coupling process. Therefore, the support table 5 is advantageously hydraulically lifted (vertically movable).

In einer anderen Ausführungsform kann auf die hydraulische Verfahrbarkeit verzichtet werden, wenn das Hilfskraftfahrzeug mit hydraulischen, teles­kopierbaren Abstützungen 9 ausgerüstet wird.In another embodiment, the hydraulic movability can be dispensed with if the auxiliary motor vehicle is equipped with hydraulic, telescopic supports 9.

Nach Fig. 2 ist die Trennstelle im Betonverteilermast zwischen Grund­rahmen 8 und Drehturm 3 angeordnet. Für den Zusammenbau des Betonver­teilermastes werden beide Kraftfahrzeuge in Montagestellung gefahren. Dann erfolgt vom 2. Kraftfahrzeug aus das Ausfahren des teleskopier­baren Mast-Teilstückes 9 mit dem Drehturm 10 mit Einsatzteil bis in die Einfahrposition zum Grundrahmen 8. Nach dem form- und kraft­schlüssigen Anschluß beider Mastteile und den Hydraulikverbindungen einschließlich der Betonrohrleitung wird das Mastpaket vom 2. Kraft­fahrzeug abgenommen.2, the separation point is arranged in the concrete placing boom between the base frame 8 and the turret 3. To assemble the concrete placing boom, both motor vehicles are driven in the assembly position. The telescopic mast section 9 with the turret 10 with the insert part then extends from the second motor vehicle into the retracted position to the base frame 8. After the positive and non-positive connection of both mast parts and the hydraulic connections including the concrete pipeline, the mast package is Motor vehicle removed.
