Description
Die Erfindung betrifft einen auswechselbaren Zweischalengreifer nach dem Oberbegriff des Anspruchs 1.The The invention relates to a replaceable clamshell grab the preamble of claim 1.
Übliche Zweischalengreifer und insbesondere an Löffelstiele von Baggern ankuppelbare Zweischalengreifer müssen bei einem Verschleiß oder zum Zwecke des Austausches gegen Zweischalengreifer anderer Größen austauschbar sein. Üblicherweise wird ein derartiger Austausch dadurch vorgenommen, dass die Greiferschalen des Zweischalengreifers ausgetauscht werden. Ein derartiger Austausch der vollständigen Zweischalengreifer-Einheit läßt sich grundsätzlich einfach und schnell durchführen. Er ist jedoch insofern aufwendig, als vollständige Zweischalengreifer-Einheiten bereitgehalten werden müssen, was höhere Investitionskosten bedingt.Usual clamshell claws and in particular on dipper sticks Dismountable clamshell clamshell must in case of wear or Exchange purposes for clamshell buckets of other sizes interchangeable be. Usually Such exchange is made by the gripper shells of the clamshell bucket. Such an exchange the complete Clamshell unit can be in principle perform easily and quickly. However, it is so far consuming, as a full clamshell units have to be kept ready what higher Investment costs conditionally.
Zweischalengreifer
nach dem Oberbegriff des Anspruchs 1 sind beispielsweise aus
Aufgabe der Erfindung ist es, Zweischalengreifer der eingangs angegebenen Art zu schaffen, die sich mit geringerem Investitionsaufwand bei einem Verschleiß oder zum Austausch gegen unterschiedliche Größen wechseln lassen.task The invention is clamshell grab the above-mentioned To create kind, which contributes with lower capital expenditure a wear or to exchange for different sizes.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß jeder Träger zwischen seinen Gelenken mit einem querverlaufenden Rohr verbunden ist, das beidseits des Trägers mit zu diesem parallelen auskragenden Stegen versehen ist, daß in dem oberen Randbereich jeder Schale zwei zueinander parallele, mit den Seitenwänden verbundene Tragprofile angeordnet und die Stege an ihren Enden mit zu den Tragprofilen komplementären Ausnehmungen, mit denen diese die Tragprofile übergreifen, versehen sind und daß in dem Rohr ausfahrbare und einziehbare Verriegelungsbolzen angeordnet sind, die in Bohrungen der Seitenwände oder von die Tragprofile verbindenden Laschen greifen.According to the invention this Task solved by that everybody carrier between his joints is connected to a transverse pipe, on both sides of the carrier provided with this parallel projecting webs that in the upper Edge region of each shell two parallel to each other, connected to the side walls Carrying profiles arranged and the webs at their ends with the support profiles complementary Recesses with which they overlap the support profiles, are provided and that in arranged extendable and retractable locking bolt the tube are in the holes of the sidewalls or of the support profiles access connecting tabs.
Aus
der
Zweckmäßigerweise bestehen die Tragprofile aus Rohren.Conveniently, the support profiles consist of tubes.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß die Innenseiten der die Tragprofile verbindenden Laschen einen Abstand voneinander aufweisen, der dem Abstand der äußeren Seiten der Stege entspricht. Auf diese Weise lassen sich die mit dem Schalenträger verbundenen Kupplungsteile besonders gut und fest mit dem durch die Tragprofile und Laschen gebildeten Gegenkupplungsteile der Schalen verbinden.In Another embodiment of the invention is provided that the insides the lugs connecting the support profiles are at a distance from each other, the distance between the outer sides the webs corresponds. In this way can be connected to the shell carrier Coupling parts particularly well and firmly with the through the support profiles and Connecting straps formed counter-coupling parts of the shells.
Zweckmäßigerweise ist in die Verriegelungsbolzen eine Spindel mit endseitigen gegenläufigen Gewinden eingeschraubt, deren eine Seite durch Bohrungen zugänglich ist, so daß sie durch einen Steckschlüssel betätigt werden kann. Durch einen zweckmäßigerweise mit einer Kurbel versehenen Steckschlüssel lassen sich sodann Verriegelungsbolzen aus- und einfahren. Nach dem Ankuppeln kann die auch eine Seitenwand jedes Greifers durchsetzende Bohrung durch einen Stöpsel verschlossen werden, so daß sie sich während des Betriebes nicht zusetzen kann.Conveniently, is in the locking bolt a spindle with end-side opposing threads screwed in, one side of which is accessible through holes, so that you through a socket wrench actuated can be. By a convenient with a cranked socket wrench can then lock bolt extend and retract. After coupling it can also be a side wall each gripper passing through hole to be closed by a plug, so that you while of the company can not enforce.
