"Cable drum without grinding ribs for movable S.

For supplying energy to electrically driven, movable ones Devices are used with cable drums with a spring or electric drive »Simple cable drums have the disadvantage of energy to be transmitted via slip rings. Abrasion from coal dust can easily lead to short circuits or undesired current transitions between the slip rings. The latter is especially at the transmission of small control currents disadvantageous and makes automatic Circuits via slip rings are problematic. The disadvantages as described above are attempted to eliminate that two drums work correspondingly separately from one another on one axis »This avoids the slip rings, creates, however, a complex 2-drum arrangement with Spring or electric drive. It also appears to be disadvantageous that the cable is bent over two planes lying at right angles to one another which will affect the service life.

The invention is based on the object of creating a device which makes it possible to produce a multi-core device in a simple manner Winding and unwinding cables, avoiding slip rings and the to avoid known, unsatisfactory auxiliary drives. By solving the task a safe power transfer should be achieved can be achieved, so that a trouble-free operation even in the open air Operation is possible. Furthermore, the aim is to ensure that the

disadvantageous entanglement of the cable in known cable drums is avoided on the drum by disorganized cable feed. Schiiessljch is a simple electrical disconnection device to create when the cable length runs out. In the case of known cable drums, this has been poorly solved and often leads to cable tears «

Solution of the task:

According to the invention, at least two axles (i) are provided on each of which at least 2 rollers (2) are rotatably arranged »Preferably one axle is above and fixed, a second underneath it is loosely arranged» The weight of the loose axle including the knuckles on it is so chosen so that the weight can wind up the cable (3) wrapped around the rollers. The toothed or chain wheels (k) arranged on the loose axis, which engage in fixed racks or chains (5) at least on both sides, always enable parallel shifting of the axes. A main power switch (6 ) for the ünterbrpchun ^ of the power supply, so a cable demolition is sicripr prevented According to the invention, a Verschlin ^f r> n the cable wi '? Completely avoided in known drums by the arrangement of a large number of rollers on the sleeves and a corresponding stroke of the loose axis, relatively large cable lengths can be wound up ,
