Abstract

In this floating dredger, the closing action of the grab 1 is repeatedly interrupted by means of an additional control system 2, 3, and 4 in order to carry out loosening and scraping movements so that optimum filling of the grab is obtained even in the most difficult material structure. <IMAGE>

Description

Multigripp für SchwimmbaggergreiferanlagenMultigripp for dredger grab systems

Die Erfindung bezieht sich auf eine Schwimmbaggergreiferlage zur Sand- und Kiesgewinnung, bei der nach Anlauf der tatsächlich benötigten Schließzeit der gefüllte Baggergreifer angehoben werden kann.The invention relates to a dredger gripper layer for sand and gravel extraction, after which the the filled excavator grab actually required the closing time can be raised.

Bekannt sind Schwimmbaggergreiferanlagen, bei denen das Volumen des Greifers nicht rentabel ausgenützt wird. Auch beim Hydraulikgreifer erfolgt nach Ablauf der Schließzeit automatisch ohne Kontrolle das Abheben des Greifers.Dredger grab systems are known in which the Volume of the gripper is not used profitably. Also the hydraulic gripper takes place after the closing time has expired automatically lifting the gripper without checking.

Die Erfindung will hier, entsprechend wie in den Ansprüchen gekennzeichnet ist, Abhilfe schaffen. Diese Aufgabe wird durch eine eingebaute elektrische Steuerung in den Schließvorgang des Greifers gelöst, wobei durch das mehrmalige kurze Öffnen bzw. Schließen des Greifers ein besserer Grabvorgang ermöglicht wird, auch schwieriges Material wird besser gelöst und eine positivere Ausnutzung des Greifervolumens garantiert. Beim Hydraulikgreifer ist nach entsprechender Steuerung der Hydraulik der gleiche Effekt zu erzielen.The invention aims here, as in the claims is marked to remedy the situation. This task will through an integrated electrical control in the closing process loosened the gripper, whereby by the repeated short opening or closing of the gripper a better digging process is made possible, even difficult material better solved and a more positive utilization of the gripper volume guaranteed. The hydraulic gripper is according to Control the hydraulics the same effect too achieve.

Diese Steuerung ermöglicht eine größere Förderleistung von entsprechendem Baggergut, wie bei den bekannten Ausführungen.This control enables a greater delivery rate of appropriate dredged material, as in the known designs.

Die Erfindung wird mit einem Ausführungsbeispiel anhand einer schematischen Zeichnung dargestellt und nachstehend näher erläutert.The invention is based on an exemplary embodiment schematic drawing shown and explained in more detail below.

Der Schließvorgang des Greifers 1 beim Greifen des Gutes unter Wasser mit Nachfassen erfolgt über eine Zusatzeinrichtung 2, einem Programmwähler 3 zum Öffnen und Schließen sowie über eine Steuerung 4, die die mehrmalige Schürf- und Lockerungsbewegung einleitet und überwacht. Die Steuerung erfolgt über das Zweimotorenwindwerk mit der Haltetrommel 5 und Schließtrommel 6. Das Schema zeigt den Greifer 1 mit ausgezogenen Linien in geschlossenem Zustand und mit gestrichelten Linien in Lockerungs- und Schürfstellung.The closing process of the gripper 1 when gripping the goods under water with follow-up takes place via an additional device 2 , a program selector 3 for opening and closing and via a control 4 which initiates and monitors the repeated scraping and loosening movement. The control takes place via the two-motor winch with the holding drum 5 and the closing drum 6 . The diagram shows the gripper 1 with solid lines in the closed state and with dashed lines in the loosening and scraping position.

Bei Einsatz eines Hydraulikgreifers mit gleichem Windwerk werden die Lockerungs- und Schürfbewegungen mit der Zusatzsteuerung über das Hydraulikaggregat eingeleitet. Diese Art der Ausführung ist im Schema nicht näher erläutert.When using a hydraulic gripper with the same winch the loosening and scraping movements with the additional control initiated via the hydraulic unit. This kind the execution is not explained in the diagram.
