Abstract
Description
Die Erfindung bezieht sich auf ein mobiles Arbeitsgerät, insbesondere eine Autobetonpumpe, mit einem Fahrgestell, mit vorderen und/oder rückwärtigen, von einer Fahrstellung in mindestens eine Abstützstellung ausfahrbaren und mit je einem in einem Mantellrohr verschiebbaren Teleskopbein auf einer Unterlage abstützbaren Stützauslegern, wobei das Teleskopbein einen an einem vorzugsweise als Kugelgelenk ausgebildeten Fußgelenk angelenkten Fußteller trägt, der auch im eingefahrenen Zustand des Teleskopbeins zusammen mit dem Fußgelenk aus dem Mantelrohr herausragt.The invention relates to a mobile work tool, especially a truck-mounted concrete pump, with a chassis, with front and / or backwards, extendable from a driving position into at least one support position and with a telescopic leg that can be moved in a jacket tube a supportable Outriggers, the telescopic leg one on a preferably as a ball joint trained ankle articulated footplate wearing, which together with when the telescopic leg is retracted the ankle protrudes from the casing tube.
Die an dem Arbeitsgerät angeordneten Stützausleger sollen am Einsatzort die Standfestigkeit des Arbeitsgeräts verbessern. Sie haben dabei die Aufgabe, die Fahrzeugfederung zu eliminieren und die Räder zu entlasten. Zum anderen sollen die Stützausleger die Kippgefahr mindern, die sich ergibt, wenn über einen Arbeitsausleger hohe Kipplasten entstehen. Der gelenkig am Teleskopbein angeordnete Fußteller sorgt dafür, dass sich die Stützausleger beim Abstützvorgang an eine gegebene Bodenkontur anpassen können. Das zwischen Teleskopbein und Fußteller angeordnete Fußgelenk ist sowohl beim Abstützvorgang als auch beim Fahrbetrieb einer Verschmutzung ausgesetzt, durch die die Funktion des Fußtellers beeinträchtigt werden kann.The arranged on the implement outriggers should improve the stability of the implement at the place of use. You have the task of eliminating the vehicle suspension and the wheels to relieve. On the other hand, the outriggers should reduce the risk of tipping, which arises when over high working loads arise. The articulated on Telescopic foot plates ensures that the outrigger during the support process can adapt to a given ground contour. The one between the telescopic leg and foot plate arranged ankle is both in the support process exposed to pollution as well as while driving, by the function of the foot plate impaired can be.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, Vorkehrungen zu treffen, die eine Verschmutzung des Fußgelenks vor allem beim Fahrbetrieb reduziert.The invention is based on this the task is to take precautions to prevent pollution of the ankle especially reduced when driving.
Zur Lösung dieser Aufgabe werden die im Anspruch 1 angegebenen Merkmale vorgeschlagen. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To solve this problem proposed the features specified in claim 1. advantageous Refinements and developments of the invention result from the dependent Claims.
Die erfindungsgemäße Lösung ist vor allem darin zu sehen, dass am Mantelrohr eine Schutzhülse lösbar befestigt ist, die mit einer Hülsenpartie über das freie Ende des Mantelrohrs übersteht und im eingezogenen Zustand des Teleskopbeins das Fußgelenk übergreift.The solution according to the invention is above all in there see that a protective sleeve is releasably attached to the casing tube, which with a sleeve section over the protrudes free end of the casing tube and overlaps the ankle when the telescopic leg is retracted.
Vorteilhafterweise ist die Schutzhülse mit einem Schlauchband am Mantelrohr befestigt. Deshalb weist die Schutzhülse zweckmäßig eine Umfangsnut zur Aufnahme des Schlauchbandes auf.The protective sleeve is advantageously included attached to the jacket tube with a hose band. Therefore, the protective sleeve expediently has one Circumferential groove for receiving the hose band.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist die Schutzhülse zylindrisch. Um das Fußgelenk enger zu umschließen, kann es von Vorteil sein, wenn die überstehende Hülsenpartie zumindest partiell zu ihrem freien Ende hin konisch verjüngt ist.According to a preferred embodiment of the Invention is the protective sleeve cylindrical. Around the ankle to enclose more closely it can be an advantage if the protruding sleeve section is at least partially tapered towards its free end.
Vorteilhafterweise ist die Schutzhülse als Formteil vorzugsweise aus einem elastomeren Kunststoff ausgebildet.The protective sleeve is advantageously a molded part preferably made of an elastomeric plastic.
Um den Fußteller im eingezogenen Zustand des Teleskopbeins auch in Schräglage halten zu können, kann es von Vorteil sein, wenn die überstehende Hülsenpartie an ihrer freien Endkante eine Ebene aufspannt, die mit einer zur Hülsenachse senkrechten Ebene einen spitzen Winkel einschließt.To the foot plate in the retracted state of the Telescopic legs also in an inclined position to be able to hold it can be an advantage if the protruding sleeve section on its free end edge spans a level that with one to sleeve axis vertical plane encloses an acute angle.
Im Folgenden wird die Erfindung anhand der Zeichnung näher erläutert. Es zeigenThe invention is described below closer to the drawing explained. Show it
