Definitions

  • the invention relates to a synthetic fiber rope, preferably made of aromatic polyamide, with a covering according to the generic term of claim 1.
  • Ropes are particularly useful in conveyor technology, e.g. at Elevators, in crane building and mining, an important strong stressed machine element. It is particularly complex Stress on driven ropes, via rope pulleys deflected ropes or ropes wound on drums, such as it is used, for example, in elevator construction and on cable cars become. Large pitches are necessary there and it exists for energetic reasons the demand for the smallest possible Masses.
  • High-strength synthetic fiber ropes for example made of aromatic polyamides or aramids with high grade oriented molecular chains better meet these requirements than conventional steel cables.
  • materials are like e.g. Aramids, particularly sensitive to ultraviolet (UV) light, oxidizing and reducing environmental influences, by which the breaking force and the work capacity are reduced become. Aramid ropes are therefore usually included light-resistant material encased or braided.
  • the invention is based on the object Reduce the manufacturing costs for a synthetic fiber rope, while ensuring an unchanged high functionality is.
  • the advantages achieved by the invention are: permanent binding of the sheath to the synthetic fiber strands of the outer strand layer, because the material of the covering and the the synthetic fibers of the strand fixing matrix are the same.
  • the mere addition of appropriate additives can Functionality over the entire lifespan of fiber ropes can be easily extended.
  • the inventive Enclosure neither forms upsets nor is it displaceable on the synthetic fiber strands.
  • the casing is produced largely without additional device-related effort and is simple and inexpensive.
  • Starting from mass production conventional synthetic fiber strands are the Synthetic fiber strands for the outermost fiber strand layer only through an existing impregnation bath to to form the coating according to the invention.
  • the Layer thickness is based on the dwell time of the synthetic fiber strand in the Impregnation bath adjustable.
  • the coating process can also can be repeated any number of times.
  • a particularly abrasion-resistant embodiment of the coating is made by adding short fibers, e.g. aramid, reached to the impregnation bath.
  • the strands 2,3,4 and 5 consist essentially of Aramid yarns 8 that are helical in a matrix Polyurethane are fixed.
  • Aramid yarns 8 For stranding or turning the Aramid yarns 8 with a protective impregnating agent, treated with a polyurethane solution, for example.
  • the share of Polyurethane on each strand 2,4,5 is decisive for the bending fatigue strength of the rope 1.
  • the polyurethane part for impregnating the strands 2,4,5 can, for example, depending on the desired rope properties are between ten and sixty percent.
  • exemplary seven aramid yarns 8 by impregnation into a filament 7 connected and fixed.
  • the impregnation forms everything single filament 7 a protective thin layer 9.
  • seven of the Filaments 7 are helical to one another Stranded 2,3,4,5 struck.
  • the filaments 7 do not have those in the drawing shown circular shape, but are on the surface adjoining filaments and strands. So far the structure of all strands used in the embodiment 2,3,4,5 basically the same, but the number of Twists per meter between the different strands and the strands with different strand diameters be different.
  • each of the thick strands 4 and 4 stranded in the cover layer 6 thin strands 5 is according to the invention of an additional Protective layer 10 encased in impregnating agent.
  • This Protective layer is advantageously by additional Soak in a impregnation bath in a continuous process the surface of the thick strands 4 and thin strands 5 educated.
  • the impregnating agent also contains Additions of UV stabilizers, preferably silicon crystals, Oxidation and reduction blockers.
  • the thickness 11 of the protective layer 10 around the individual strands 4, 5 here is 0.2 mm; According to the invention, however, it can Range between 0.1 and 1 mm depending on the desired protective effect to get voted.
  • the protective layer 10 acts as an abrasion protection between the thick strands 4 and the thin strands 5 of the Cover layer 6 and forms 4.5 of the cover layer in association with all strands 6 externally an effective as well as inexpensive Sheathing of the rope to be produced 1. On an additional Rope sheath made of plastic can therefore be dispensed with.
  • Coated according to the invention with a protective layer 10 Strands 4, 5 can be prefabricated and semi-finished then as required using conventional stranding machines be further processed, which is the manufacturing cost of Aramid fiber rope 1 significantly reduced.
  • Impregnant can also be used with another liquid Adhesive property to be applied to the rope.
  • the rope can also be used use a wide variety of conveyor systems, e.g. For Elevators, mine hoists in mining, load cranes such as construction, Hall or ship cranes, cable cars and ski lifts as well as Traction devices for escalators.
  • the drive can both by Friction over traction sheaves or Koeppe sheaves as well by rotating rope drums on which the rope is wound will be done.
  • Under conveyor rope is a running, to understand driven rope, sometimes as a pull or Carrier rope is called.
