Description
Die Erfindung betruit einen Knickausleger für eine Autobetoiipumpe mit einem auf einem Fahrzeug angeordneten Drehturm, der zwei mit Abstand zueinander angeordnete Wände aufweist, zwischen deren oberen Enden der Unterarm eines dreiteiligen, mit einer Betonförderleitung versehenen Auslegearms gelagert ist, dessen Mittel- und Oberarm gegeneinander eingeknickt unter den Unterarm einklappbar sind.The invention betruit an articulated boom for one Car toilet pump with one on a vehicle arranged turret, which has two spaced apart walls, between the the upper ends of the forearm of a three-part extension arm provided with a concrete delivery line is whose middle and upper arm can be folded under the forearm when they are bent against each other.
Ein Knickausleger dieser Art ist aus der US-Patentschrift 34 59 222 bekannt. Das Einklappen des Mittelarms und des Oberarms unter den Unterarm hat hierbei μ Vorteile im Hinblick au' die Manövrierbarkeit, jedoch hat der bekannte Knickausleger den Nachteil, daß wegen der Anordnung des Mittelarms und des Oberarms unter dem Unterarm die Reichweite beschränkt istAn articulated boom of this type is known from US Pat. No. 3,459,222. The folding of the middle arm and the upper arm under the forearm has advantages in terms of maneuverability, however the known articulated boom has the disadvantage that because of the arrangement of the central arm and the Upper arm under the forearm the reach is limited
Aus der deutschen Auslegeschrift 12 04 795 ist ferner ein Knickausleger für einen Autokran bekannt, der zwei gleichsinnig gegeneinander einknickbare Arme aufweist, die an einem Drehturm befestigt sind. Zur Verlängerung der Reichweite dieses Autokranes ist «0 vorgesehen, daß der äußere Arm des Knickauslegers verlängert ausgebildet ist. Damit dieser verlängerte Arm beim Zusammenfalten des Knickauslegers nicht mit dem Drehturm kollidiert, kann der Drehturm eine öffnung aufweisen, in die das freie Ende des Armes einschwenkbar ist. Diese Ausführungsform eines Knickauslegers hat den Nachteil, daß nur der äußere Arm eine Verlängerung erfährt, so daß der erzielte Reichweitengewinn relativ gering istFrom the German Auslegeschrift 12 04 795 is also a knuckle boom for a truck crane is known, which has two arms that can be folded in the same direction against each other, which are attached to a rotating tower. To extend the reach of this truck crane is «0 provided that the outer arm of the articulated boom is elongated. So that this extended Arm does not collide with the turret when folding the articulated boom, the turret can have a Have opening into which the free end of the arm can be pivoted. This embodiment of an articulated boom has the disadvantage that only the outer arm is lengthened, so that the range gain achieved is relatively low
Es ist Aufgabe der Erfindung, die Reichweite eines Knickauslegers der eingangs genannten Art zu vergrößern, ohne die voiteilhafte Anordnung des Mittelarms und des Oberarms unter dem Unterarm zu beeinträchtigen. It is the object of the invention to increase the range of an articulated jib of the type mentioned at the beginning, without affecting the advantageous arrangement of the middle arm and the upper arm under the forearm.
Die Lösung dieser Aufgabe besteht nach der Erfindung darin, daß die aneinander angelenkten Enden des Mittelarms und des Oberarms zwischen den Wänden des Drehturmes hindurchschwenkbar sind.The solution to this problem is, according to the invention, that the hinged ends the middle arm and the upper arm can be pivoted through between the walls of the turret.
Der Knickausleger gemäß der Erfindung ermöglicht in besonders vorteilhafter Weise einen Reichweitengewinn, der maximal etwa der doppelten Höhe des Drehturmes entsprichtThe articulated boom according to the invention enables a range gain in a particularly advantageous manner, which corresponds to a maximum of about twice the height of the turret
Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnung näher erläutert Es zeigtAn embodiment of the invention is in The following is explained in more detail with reference to the drawing. It shows
F i g. 1 einen auf auf einem Fahrzeug montierten Knickausleger gemäß der Erfindung in Seitenansicht undF i g. 1 shows an articulated boom according to the invention, mounted on a vehicle, in side view and
F i g. 2 einen senkrechten Schnitt durch den in F i g. 1 dargestellten Knickausleger.F i g. 2 shows a vertical section through the FIG. 1 articulated boom shown.
Auf einem nicht näher bezeichneten Fahrzeug befindet sich ein Drehturm 1 mit der Höhe H, der aus zwei mit Abstand zueinander angeordneten Wänden besteht Am oberen Ende des Drehturmes 1 ist ein dreiteiliger, zusammenklappbarer Auslegerarm befestigt, der aus einem Unterarm 2, einem Mittelarm 3 und einem Oberarm 4 besteht In der Zeichnung ist der Knickausleger in der zusammengefalteten Stellung (Transportstellung) dargestellt, bei welcher der Oberarm 4 zwischen dem Unterarm 2 und dem Mittelarm 3 liegt. Die aneinander angelenkten Enden 5 des Mittelarms 3 und des Oberarms 4 sind zwischen den Wandungen des Drehturmes 1 hindurchschiV"inkbar, so daß sowohl der Mittelarm 3 als auch der Oberarm 4 etwa um die Höhe H des Drehturmes i verlängert ausgeführt werden können. Zur Förderung von Beton ist an dem Knickausleger eine Betonförderleitung 6 befestigt.On an unspecified vehicle is a turret 1 with the height H, which consists of two spaced apart walls Upper arm 4 consists. In the drawing, the articulated boom is shown in the folded-up position (transport position), in which the upper arm 4 lies between the lower arm 2 and the middle arm 3. The mutually hinged ends 5 are of the central arm 3 and the upper arm 4 so that both the center arm 3 and the arm 4 is about the height H of the turret can be carried out i extends between the walls of the turret 1 Hindu r chschiV "inkbar. For Conveying concrete, a concrete delivery line 6 is attached to the articulated boom.
