Abstract

A monitor for the motors of a traversing double drive for grab-dredger systems. In the case of this monitor, the current flowing through the two motors 1 and 2 is measured by the differential relay 3 and, in the event of an uneven load, emits a visual or audible signal 4 to the control console and/or disconnects the traversing mechanism via contact 5.

Description

Oberwachung der Motoren eines KatzfahrdoppelantriebesMonitoring of the motors of a double trolley drive

für Schwimmgreiferanlag.en Die Erfindung bezieht sich auf die Oberwachung der Motoren des Katzfahrdoppelantriebes einer Greiferlaufkatze für S.chwimmgr.eiferanlagen zur Sand- und Kiesgewinnung mittels Diff-erentia-lrelais, die den Durchfluß des Stromes bei-der Motoren überwachen und bei unterschiedlichen Belastungen ein elektrisches Signal abgeben.for floating gripper systems. The invention relates to monitoring of the motors of the double trolley drive of a gripper trolley for floating grapple systems for sand and gravel extraction by means of differential relays, which control the flow of the Monitor the current of the motors and an electrical one in the case of different loads Send signal.

Die Messung des Stromrdurchflusses und die Anzeige ermöglicht ein rechtzeitiges Erkennen einer unterschiedlichen Belastung beider Ketzfahran-triebe.The measurement of the flow rate and the display enables a early detection of a different load on both Ketz travel drives.

Bei den bekannten Allradantrieben von Greiferlaufkatzen für Schwimmgreiferanlagen werden zum Teil elektrische Wellen verwendet, die aber bei diesem rob-usten Betrieb sehr störanfällig und zudem noch sekr aufwendig sind.In the known all-wheel drives of gripper trolleys for floating gripper systems Electric waves are sometimes used, but they are used in this robust operation are very prone to failure and are also very expensive.

Nach der Erfindung soll hier entsprechend den Anspruch mit einer einfacheren Lösung Abhilfe geschaffen werden. Die Aufgabe wird dadurch gelost, daß ein Dtfferentialrelais den Stromdurchfluß der beiden Motoren überwacht und bei Anderun.-gen des Durchflusses in der Steuerka-bine ein akustisches S-i-gnal- abgibt und oder durch einen Kontakt das Katzfahrwerk abschaltet. Dadurch werden Fehler rechtzeitig erkannt und eine Oberlastung des ungestörten Antriebes vermieden.According to the invention, the claim should be based on a simpler one Solution remedy to be created. The task is solved in that a differential relay the current flow of the two motors is monitored and in the event of changes in the flow in the control cabin emits an acoustic S-i signal and / or through a contact the trolley switches off. As a result, errors are recognized in good time and a Overloading of the undisturbed drive avoided.

Im folgenden wird die Erfindung anhand von lediglich einem Ausführungsweg darstellenden Obersichtsplan näher erläutert.In the following, the invention is illustrated by means of only one embodiment Representative overview plan explained in more detail.

Der Stromdurhfluß der beiden Moto-ren 1 und 2 wird durch Differenti-a.lrelais 3 überwacht, wobei bei ungleicher Belastung eine Lampe 4 in der Steuerkabine aufleuchtet und gleichzeitig ein akustisches Signal ertönt und oder über einen Kontakt 5 das Katzfahrwerk gleich abschaltet.The current flow of the two motors 1 and 2 is controlled by differential relays 3 monitored, whereby a lamp 4 lights up in the control cabin if the load is uneven and at the same time an acoustic signal sounds and or via a contact 5 the The trolley will switch off immediately.
