Vorliegende Erfindung bezweckt die Schaffung eines Meßgerätes für Förderseile, insbesondere bei Mehrseilbetrieb, zur laufenden Betriebsüberwachung, indem die Seilbelastung in den einzelnen Seilen gemessen wird.The present invention aims to provide a measuring device for hoisting ropes, in particular in Multi-rope operation, for ongoing operational monitoring by reducing the rope load in the individual Ropes is measured.
Es ist bereits bei Einseilförderung vorgeschlagen worden, die dynamischen Seilbelastungen mit Hilfe von Dehnungslaschen und Feindehnungsmessern zu ermitteln. Die Messung mit Dehnungslaschen hat den Xachteil. daß die Meßlaschen auf Zug beanspruchte Tragelemente sind, die zur Erzielung einer ausreichenden Dehnung nicht zu stark überdimensioniert werden dürfen. Aus Sicherungsgründen müssen hierbei besondere Fanglaschen vorgesehen werden, die beim etwaigen Bruch der Meßlaschen das Abstürzen der angehängten Förderlast, z. Ii. der Förderkörbe, verhindern.It has already been proposed for single rope conveying to use the dynamic rope loads of expansion tabs and fine strain gauges. The measurement with expansion tabs has the disadvantage. that the measuring tabs are stressed on train support elements to achieve sufficient expansion must not be overdimensioned too much. For security reasons special catch straps must be provided in the event that the measuring straps break the falling of the attached load, e.g. Ii. the conveyor baskets.
Die ebenfalls bekannten Feindehnungsmesser sind als Meßgeräte zur laufenden Betriebsüberwachung sehr empfindlich; außerdem erfordern sie zur Bedienung besondere Sachkenntnis. Die gleiche Empfindlichkeit haben auch die elektrischen Meßgeräte, die eine besondere Stromquelle erfordern. Den bekannten Dynamometern, die mit Schraubenfedern arbeiten, haftet der Nachteil an, daß sie durch ihre Eigenelastizität die Elastizität des zu untersuchenden Systems ändern, insbesondere dann, wenn beim Stand des Förderkorbes an der Hängebank die federnde Oberseillänge nur klein ist.The fine extensometers, which are also known, are used as measuring devices for ongoing operational monitoring very sensitive; they also require special expertise to operate. The same Electrical measuring instruments also have sensitivity, that require a special power source. The well-known dynamometers with coil springs work, there is the disadvantage that, through their own elasticity, they reduce the elasticity of the object to be examined Change the system, especially if the resilient upper rope length is only small.
Gegenüber diesen bekannten Meßvorrichtungen wird erfindungsgemäß ein Meßgerät mit einem auf Druck beanspruchten Meßkörper vorgeschlagen, mit dessen Hilfe die Belastung in den einzelnen Förderseilen meßbar ist. Vorteilhaft besteht der MeßkörperCompared to these known measuring devices, according to the invention, a measuring device with a Pressure-stressed measuring body proposed, with the help of which the load in the individual conveyor ropes is measurable. The measuring body is advantageously made
