Embodiment Construction

[0048] figure 1 A chain drive 1 is shown as an example in the form of a chain conveyor with two sprockets 2 , 3 and a conveyor belt 4 driven by them with an upper run 5 and a lower run 6 . The drive element 7 is arranged as main drive element on the sprocket 2 , schematically drawn on the left, in order to drive this sprocket. A further drive 8 is arranged as an auxiliary drive on the other sprocket 3 in order to drive the other sprocket.

[0049] The control device 9 serves to control the drives 7 , 8 . By way of example, the control device 9 is connected to the drives 7 , 8 via lines 10 , 11 , wherein other transmission systems, in particular, can also be used for the measurement and control signals. In particular, control signals s1 , s2 for actuating the drives 7 , 8 can be transmitted from the control device 9 to the drives 7 , 8 . The conveyor belt 4 , which can be driven by means of the drives 7 , 8 , is used for transporting the conveyed material 12 , for example pu...

Abstract

The invention relates to a method for operating a chain drive (1), which has sprockets (2, 3), wherein chain tension moments (M1, M2) on the sprockets (2, 3) are determined and a specification value ([delta]L) for the operation of the chain drive (1) is determined therefrom in an automated manner. The invention further relates to an assembly, comprising a chain drive having sprockets (2, 3) and a control device (9) at least partially associated with the chain drive (1), wherein the control device (9) is designed and / or programmed to perform the method and a specification value for the distribution of load among the two driving devices (7, 8) for the operation of the chain drive (1) is determined therefrom in an automated manner.

Description

technical field [0001] The invention relates to a method for operating a chain drive and an installation having a chain drive and a control device for carrying out the method. Background technique [0002] On chain drives with endless loops, as they are used e.g. in chain scraper conveyors in underground coal mines , which is also known as armored conveyor AFC (scraper conveyor, Armored Face Conveyor) or section loader (English: Stageloader) and planing unit, the correct choice of chain preload is crucial to the operation safety and service life of the facility important. It is known to also use drives with hydrodynamic clutches in this case. [0003] If the chain tension of the chain of the chain drive is too low, then a vertical chain will form behind the drive part of the chain and lead to kinks of the chain mainly in the lower running section, that is to say on the lower return side of the chain drive ( Verklanken) with the chain rope locking and subsequent chain b...
