Abstract

Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur Überwachung des Betriebs von Hubwinden von Kränen, wobei auf die Hubwinde (1) wirkende Seilkräfte dynamisch bestimmt, Lastwechsel und eine dynamische Beanspruchung ermittelt und/oder eine Restlebensdauer bestimmt werden. Erfindungsgemäß ist vorgesehen, daß ein Drehmoment eines Hubwindenantriebs (2) bestimmt wird, ein Hebelarm des Seils (4) bezüglich der Hubwinde bestimmt und zeitlich dem jeweilig bestimmten Drehmoment zugeordnet wird, und aus dem jeweiligen Drehmoment und dem zugeordneten Hebelarm die Seilkraft bestimmt wird. Aus dem zeitlichen Verlauf der Seilkraft wird das für die Lebensdauer bestimmende Lastkollektiv errechnet, aus dem die Restlebensdauer bestimmt werden kann. Darüber hinaus ist vorgesehen, die absolute Abspullänge des Seiles, dessen Geschwindigkeit und Beschleunigung sowie die Seilkraft unter Berücksichtigung der Wicklungslagen und die Windendrehzahl zu ermitteln und zu überwachen.

The present invention relates to a method and a device for monitoring the operation of hoisting winches of cranes, wherein rope forces acting on the hoisting winch (1) are determined dynamically, load changes and a dynamic load are determined and / or a remaining service life is determined. According to the invention, a torque of a hoist winch drive (2) is determined, a lever arm of the rope (4) is determined with respect to the hoist winch and is temporally assigned to the respectively determined torque, and the rope force is determined from the respective torque and the associated lever arm. The load spectrum determining the service life, from which the remaining service life can be determined, is calculated from the time course of the rope force. In addition, it is planned to determine and monitor the absolute unwinding length of the rope, its speed and acceleration as well as the rope force taking into account the winding positions and the winch speed.
