Definitions

  • the invention relates to a rope made of textile fiber material and its use.
  • Ropes made of textile fiber material for example synthetic fiber ropes, are used for numerous applications. Particularly in the field of conveyor technology, high-strength fiber ropes are already superior to the previously exclusively used or available steel ropes due to several advantages.
  • the advantages of the high-strength fiber rope are that the drives can work with a smaller ratio of pulley diameter to rope diameter than steel cables, since the fiber ropes this unlike steel cables without major disadvantages, such as Lifespan loss, allow. This results in the possibility of using smaller sizes of traction sheave drives, resulting in space and cost savings.
  • a high-strength fiber rope depending on the fiber material compared to a steel cable has a 4-6fach lighter weight, which has a favorable effect especially at high elevator heights.
  • higher permissible bending cycle numbers can be achieved by a multiple of high-strength fiber cables, resulting in a longer service life, ie lifetime, of the cable compared to steel cables.
  • the known elevator fiber ropes are designed in a variety of constructions, they usually have a sheathing of the strands and a plastic sheathing of the complete rope. The sheathing is designed in such a way that it permanently withstands the loads during running over pulleys and in particular traction sheaves.
  • Such high-strength fiber ropes for use in traction sheave elevator drives are for example from EP 0 672 781 B and the EP 0 934 440 B known.
  • Lifting applications in lifting technology do not use traction sheave drives but drum drives with multi-layered rope drums.
  • the drum drives have compared to the traction sheave drives on the additional benefit, the unnecessary rope length stored in a controlled and orderly manner. This is not the case with the traction sheave drive, since in elevator technology the entire rope length between the car and the counterweight is used and thus no storage function is necessary.
  • Drum drives in lifting technology also have a significantly higher lifting potential than traction sheave drives.
  • a controlled, trouble-free and stable drum winding over all cable layers is of fundamental importance.
  • Trommelbewicklung is a winding without gaps ("blocking") between adjacent turns of the same winding layer (“winding jump”) without cutting the rope into the underlying winding layers and without rising of the rope on the flange outside the designated pitch zones understood.
  • Stable drum winding is understood to mean little deformation of the winding package under load during the period of operation.
  • the high coefficient of friction of the cable surface in the multi-layer winding which is necessary for traction sheave drives, additionally has a negative effect, since in the multi-layer winding rope is wound over the rope and, in the event of changes in the traction force, i. when picking up or setting down load, rope slides on rope. Due to the high friction and the load due to multi-layer winding, the sheathing of the rope breaks and dissolves very quickly and the rope must be laid down.
  • the EP 0 995 832 B proposes, for use with drive pulleys and rope drums, an aramid fiber rope consisting of at least two stranded layers twisted towards the spiral rope, the individual layers of strands being separated by an intermediate layer and the outer strand layer having the inner layer of strands adjacent to it stranded opposite direction of impact.
  • the strike length ratio of the recoil stranding is 1.5 to 1.8.
  • the EP 1 004 700 B describes a synthetic fiber rope with multiple layers of strands, wherein the strands of the outermost layer is surrounded with a coating for protection against abrasion and harmful environmental influences.
  • the EP 0 252 830 B1 describes a synthetic fiber rope having a central radially elastic core.
  • the rope is continuously impregnated to the inside of the yarns with a binder.
  • the invention has as its object to provide a rope of textile fiber material for lifting applications, which can be used with drum drives and overcomes the aforementioned disadvantages of the prior art.
  • the rope should have a comparable life with steel ropes durability and capacity.
  • rope of textile fiber material means that the essential components of the rope, in particular its supporting elements of textile fiber material, such as. Strands of synthetic fibers.
  • the rope of the invention may also comprise components of other materials, e.g. a core of non-textile material, a sheath of non-textile material, the rope or rope components impregnating materials or even individual non-textile strands with special function, e.g. for transmitting electrical signals.
  • the entire rope both in terms of load-bearing and non-load-bearing components, consists of textile fiber material.
  • the high-strength fiber rope described here has optimum conditions for a multi-layer winding of drums in cable drives, in particular for applications in which steel cables were previously used.
  • the rope according to the invention in addition to the optimum conditions for the multi-layer winding of drums meets all requirements for high bending fatigue strength and high breaking strength.
  • the load-bearing fiber material of the rope according to the invention consists of high-strength plastic fibers.
  • high strength refers to fibers having a tensile strength of at least 14 cN / dtex, preferably a tensile strength of more than 24 cN / dtex, more preferably greater than 30 cN / dtex.
  • high strength fiber types with corresponding tensile strengths e.g. UHMWPE fibers (Dyneema®), aramid fibers, LCP fibers and PBO fibers are known.
  • the entire load-bearing fiber material of the rope consists of UHMWPE fibers.
  • load-bearing fiber material is meant that part of the fiber material of the rope which contributes to absorbing the tensile forces occurring during the application of the rope.
  • the cable according to the invention is in the form of a Spirallitzenseiles.
  • the textile fiber material is placed into a strand, turned or braided. Several of these strands are twisted together in several layers to form a rope.

  • the cable according to the invention has at least two, preferably at least three concentric load-bearing strand layers.
  • the respective outermost layer of strands preferably has the direction of impact opposite to the direction of impact of the inner layers of strands.
