Definitions

  • Loop car drives are known in practice, in which the car guiding the belt is moved via a cable arrangement.
  • the rope used for this is anchored on the one hand at a fixed point, is then returned to a cable winch via deflection rollers on the cable car, and is wound or unwound by rotating this cable winch.
  • the disadvantage here is a cable misalignment, which results from the winding or unwinding on the cable winch, a certain run-up angle having to be observed here.
  • Another major disadvantage is that if the car is pulled quickly towards the winch and, for example, the belt suddenly breaks, the car runs against the buffer arrangement unchecked and this can damage the car or the system itself.
  • the invention has for its object to provide a sling car drive, which is characterized by a simplified structure and in which the Sling car can be guided tied up.
  • FIG 1 the basic cable routing between loop car 5 and cable car machine 11 is shown schematically.
  • the sling carriage 5 holds the band, not shown, the band tension being indicated only by an arrow.
  • This loop carriage is provided with deflection rollers 4.
  • the deflection rollers 4 on the one hand guide the rope 14 which is supported by the pneumatic cylinder 6 and which in the example shown is connected to the cable car machine via the further deflection rollers 8 and 9 and the deflection roller 12.
  • the pull rope 15 also runs over pulleys 4 on the sling car and is held at fixed point 7. In the example shown, this pull rope 15 runs over the roller 13 into the cable car machine.
  • the cable car machine itself has, in addition to the guide rollers 12 and 13, a deflection roller 1 and a drive roller 2.
  • the deflection roller 1 is inclined relative to the drive roller, as shown in FIG Driving roller 2 takes place in different grooves. Due to this known friction drive in the cable car machine, a conventional cable winch, as was necessary in previous systems, can be dispensed with and nevertheless it is ensured that the sling wagon is constantly held by the traction cable or the fixed cable.
  • the rope 14 and the traction rope 15 were mentioned. In the actual sense, it is a single rope, one section of which acts as a tether rope and the other section as a traction rope. In the cable car machine, both cable sections merge.

1. Chariot de guidage de boucle comportant un dispositif pour l'entraînement du chariot de guidage de boucle, ensemble dans lequel le chariot de guidage de boucle maintient la bande à guider et peut être déplacé en avant et en arrière dans la direction longitudinale de la bande, par un système à câble comportant des poulies de renvoi et relié à un dispositif d'entraînement, le chariot étant simultanément retenu, et le câble de traction ainsi que le câble de retenue étant ancrés à l'extrémité éloignée du dispositif d'entraînement, à savoir le câble de traction au niveau d'un point fixe réglable quant à la longueur, et le câble de retenue au niveau d'un vérin de mise sous tension,
caractérisé par
un dispositif d'entraînement à poulie motrice connu en soi, comportant deux poulies de renvoi du câble (1, 2) espacées entre-elles, dont une poulie (1) est disposée de biais par rapport à l'autre poulie (2), de façon à ce qu'en raison de le poulie (1) disposée de biais, le câble de traction forment simultanément câble de retenue (3) est enroulé et déroulé dans la zone de rebroussement de l'autre poulie (2), dans des gorges différentes, le câble de traction formant simultanément câble de retenue étant mené et guidé par le dispositif d'entraînement à poulie motrice.
