Definitions

  • the present invention relates to a device for handling of a line that is wound onto a rotating drum, such as a winch drum, where the line which is wound up is led through a breaking body that gives a firm and approximately constant tightening to the stretch of line towards the drum, so that the line coils around the drum are lying sufficiently taut, as can be seen in the introduction of the subsequent claim 1.

  • synthetic hawsers are often used as anchor lines for floating offshore installations.
  • the manufacturers of hawsers supply the hawsers loosely wound onto storage drums.
  • the hawsers are normally spooled over onto the winches of the vessel at an offshore base.
  • the hawser So that the hawser can be made slack out from the winch on the anchor handling vessel with a load, the hawser must initially be tightly coiled.
  • a winch arrangement is described that is intended to control the tension in a steel rope or wire so that it can be spooled tightly from a storage drum to a crane winch, or the like.
  • This solution can be compared with a traditional warping end, with the exception that guides are installed that prevents the steel rope from spinning axially along the drum core when this rotates.
  • a line such as a cable, hawser or the like
  • the surface of the disc groove creates the highest possible friction against the fibrous hawser, at the same time as one shall get the smallest wear damage on the hawser if such gliding occurs.

  • the device according to the preceding claims for handling of hawsers is used for anchor handling, with the hawsers being loosely wound up on storage drums from the supplier, as the hawser from the storage drum is transferred to a very tightened condition by being wound onto a winch drum (11 ) with such a force that it lies compact and taut on the drum.
  • the device can according to the preceding claims also be used in the tightening of wires, cables, fibrous hawsers, and the like, on winch drums in connection with cranes.

Abstract

L'invention concerne un dispositif pour manipuler une ligne qui est enroulée sur un tambour rotatif, la ligne enroulée étant entraînée à travers un corps de rupture (20) qui permet de serrer de façon ferme et approximativement constante la partie de la ligne en direction du tambour, de sorte que les bobines de la ligne autour du tambour soient suffisamment serrées. Le dispositif est caractérisé en ce que le corps de rupture (20) comprend des unités de rupture (21,22,23) qui offrent une résistance contre l'enroulement du tambour (11) de la ligne, ledit corps de rupture (20) comprenant un certain nombre de disques de guidage de ligne (21,22,23), par le biais desquels la ligne est guidée pour être installée et former une boucle, les cannelures de guidage desdits disques (36) offrant ledit effet de rupture contre l'aussière, jusqu'au tambour (11). Selon l'invention, le dispositif peut être utilisé dans la manipulation d'aussières pour la fixation d'ancrage qui sont enroulées de manière lâche sur des tambours de stockage provenant du fournisseur, l'aussière provenant du tambour de stockage étant transférée dans un état considérablement serré, en étant enroulée sur un tambour de treuil avec une force telle qu'elle reste compacte et tendue sur le tambour. Selon une autre application, il est utilisé pour le serrage de fils, de câbles, d'aussières fibreuses et similaires sur des tambours de treuil en association avec des grues.
