Insbesondere sind hier Mehrschalengreifer für den Materialumschlag betroffen. Diese dienen insbesondere der Verladung von Schüttgütern, Fein- und Grobschrott, Abbruchmaterial oder auch zum Verladen von VA-Stählen. Speziell bei Mehrschalengreifern für einen derartigen Materialumschlag ist es bei der Anmelderin bislang üblich, dass verschlissene Greiferschalenspitzen abgetrennt und neue Greiferschalenspitzen aufgeschweißt werden müssen. Es sind andere Mehrschalengreifer bekannt, bei denen es schraub- oder steckbare Zahnspitzen gibt, die nach Erreichen der Verschleißgrenze gegen neue Spitzen ersetzt werden.In particular, here are peel grab for material handling affected. These serve in particular the loading of bulk materials, fine and large scrap, Demolition material or for loading VA steels. Especially with orange peel grabs for such a material handling, it has been the Applicant so far common for worn gripper cup tips to separate and new gripper cup tips must be welded. There are other orange peel grabs known where there are screwable or pluggable tooth tips, after reaching the wear limit for new tips are replaced.

Das Auswechseln verschlissener Zahnspitzen ist aufwendig und kostenintensiv.The replacement of worn tooth tips is complicated and costly.

Aufgabe der vorliegenden Erfindung ist es, Grab- bzw. Greifwerkzeuge mit einer Greiferschale, bei der mindestens eine Zahnspitze angesetzt ist, derart weiterzubilden, dass das Auswechseln der mindestens einen Zahnspitze kostengünstig und einfach erfolgt.Object of the present invention is grave or gripping tools with a Gripper shell, in which at least one tooth tip is attached, so educate, that the replacement of at least one tooth tip cost and just done.

Demnach ist an dem Grabwerkzeug bzw. an dem Greifwerkzeug mindestens ein Zahnhalter angeordnet, in dem die mindestens eine Zahnspitze einsteckbar, in der Länge nachführbar und sicherbar ist. Es wird also am unteren Ende der Greiferschale eine lange Zahnspitze vorgesehen, die in einem beispielsweise aufgeschweißten Zahnhalter geführt ist und gegen Ausfallen gesichert ist. Der Zahnhalter ist dabei in einer günstigen Form gestaltet, so dass das Eindringverhalten nicht gestört ist. Durch die vordere Öffnung des Zahnhalters ragt die Zahnspitze soweit nach außen hervor, dass der Greifer gut schließt. Erfindungsgemäß ist die Zahnspitze derart ausgestaltet, dass sie in ihrer Länge nachführbar und nach entsprechender Nachführung festlegbar, das heißt sicherbar ist.According to the invention, this object is achieved in that a generic Grave or gripping tool the features of the characterizing part of the claim 1 has. Accordingly, on the grave tool or on the gripping tool arranged at least one tooth holder, in which the at least one tooth tip insertable, trackable and secure in length. So it's at the bottom End of the claw shell provided a long tooth tip, which in an example welded-on tooth holder is guided and secured against failure. The tooth holder is designed in a favorable shape, so that the penetration not disturbed. The front opening of the tooth holder protrudes Tooth tip out so far out that the gripper closes well. According to the invention the tooth tip is designed such that it can be tracked in its length and fixable after appropriate tracking, that is securable.

Somit kann bei fortgeschrittenem Verschleiß die Zahnspitze gelöst werden, ein Lochraster weiter herausgezogen werden und wieder gesichert werden. Ein kostenaufwendiges und umständliches Wechseln der Zahnspitzen ist damit wesentlich seltener notwendig.Thus, with advanced wear, the tooth tip can be released Lochraster be pulled out and secured again. A costly and laborious changing the tooth tips is therefore essential less necessary.

Besondere Ausgestaltungen der Erfindung ergeben sich aus den sich an den Hauptanspruch anschließenden Unteransprüchen.Particular embodiments of the invention will become apparent from the to the Main claim subsequent claims.

Demnach kann der Zahnhalter und/oder die Zahnspitze aus verschleißfestem Material, beispielsweise Stahlguss, bestehen.Accordingly, the tooth holder and / or the tooth tip made of wear-resistant material, For example, cast steel exist.

Besonders vorteilhaft kann die Zahnspitze auf einer Seite mehrere treppenartig angeordnete Taschen aufweisen, wobei im Zahnhalter an entsprechender Stelle ein Durchbruch vorgesehen ist, so dass die Taschen von außen zugänglich sind. Hierdurch kann nach entsprechendem Lösen der Sicherungsstifte durch ein Einsetzen eines entsprechenden Werkzeuges und einem zugehörigen Hammer die Zahnspitze ausgeschlagen, das heißt gelockert und nach vorne hin bewegt werden.Particularly advantageously, the tooth tip can be arranged in several steps on one side Have pockets, wherein in the tooth holder at the appropriate place Breakthrough is provided so that the pockets are accessible from the outside. hereby can after appropriate release of the locking pins by inserting a corresponding tool and an associated hammer the tooth tip knocked out, that is relaxed and moved forward.

Weiterhin kann vorteilhaft über den Zahnhalter eine Verschleißplatte aus verschleißfestem Material aufgebracht sein. Die Zahnspitze kann seitlich mehrere Bohrungen aufweisen, die ein Lochraster zur Aufnahme von Sicherungselementen bildet.Furthermore, advantageously over the tooth holder a wear plate made of wear-resistant Material applied. The tooth tip can laterally several holes have, which forms a hole pattern for receiving fuse elements.

Als Sicherungselemente können vorteilhaft Schwerspannstifte verwendet werden.As security elements can advantageously be used Schwubannstifte.

Zur Sicherung können allerdings auch Schraub- oder Klemmelemente, wie Keile, Spannzungen oder dergleichen verwendet werden.For securing, however, screw or clamping elements, such as wedges, Tensioning tongues or the like can be used.

Mit dem erfindungsgemäßen Grab- bzw. Greifwerkzeug erübrigt sich ein Abschneiden und Aufschweißen einer neuen Zahnspitze. Der Wechsel der Zahnspitze ist einfach und schnell durchzuführen. Die Lösung führt zu einer deutlichen Verlängerung der Regenerierungsintervalle. Das große Verschleißvolumen ist insbesondere wichtig beim Verladen von VA-Stählen. Insgesamt werden die Betriebskosten deutlich gesenkt. Als Zahnspitzen lassen sich hochverschleißfeste Stähle verwenden, da es hier aufgrund der erfindungsgemäßen Lösung nicht darauf ankommt, dass diese Stähle verschweißbar sein müssten.With the grave or gripping tool according to the invention, a cut is unnecessary and welding on a new tooth tip. The change of the tooth tip is easy and fast to perform. The solution leads to a significant extension the regeneration intervals. The large wear volume is particular important when loading VA steels. Overall, the operating costs are clear lowered. Tooth tips can be used highly wear-resistant steels, because it does not matter here because of the solution according to the invention that These steels would have to be welded.
