Definitions

  • the invention relates to a sheath-free rope according to the introductory Part of claim 1.
  • Such a rope is generally known from GB 2 320 933 A, wherein according to one embodiment, the shaped strands approximately triangular cross section, with more or less strong rounded corners, and together have a round cross-section of the rope. Accordingly, in this known Wire rope strung with form strands, the strands close to attach to each other so that there is a line contact between comes the wires of adjacent strands.
  • a problem with known hoisting ropes for cable cars or Light rail often lies in the fact that the strands on the rope outer circumference can not ensure a sufficiently round surface as they do would be needed for a smooth run over roles. It comes rather to strand-induced oscillations and thus to sound Rolling noise, particularly undesirable in city cable cars are. A more round surface could be at an appropriate large number of - thin - strands can be achieved, then one Circumference can be better approximated, however, brings the increase the number of hubs has the disadvantage of being inside the stranded core insert space thereby comparatively has large cross section, which in turn means that for a given rope diameter, the metallic one. cross-section Such a rope with more strands compared to a Rope is reduced with fewer strands. In addition, by a high number of strands makes splicing of the cable difficult or even impossible made.
  • GB 1 394 362 A a tensioning element for Prestressed concrete described, with approximately trapezoidal cross sections for individual elements are shown, but it is not wires, but wires. It also lies a wrapper that is used as a ropeway for cable cars etc. is contrary.
  • GB 2 126 613 A describes shaped strands with trapezoidal Cross sections, but in a rope, in which the strands in one Plastic or rubber shell are included, and in which the Strands are preferably also constructed of plastic. Moreover, the entire rope is additionally in a tubular casing contain. A suitability as a rope for cable cars or light rail vehicles is therefore also not given.
  • An advantage of the invention is the stranded rope with trapezoidal in cross-section strands that comparatively large metallic cross-sections and thus achieved high breaking forces be able to do this, providing a comparatively round one Surface, and while ensuring an air gap between the Strands, so that the strands can not rub against each other.
  • the so-executed hoisting rope is also over long operating times and it becomes an essential Reduction of the strand-induced vibrations and thus of the Reached rolling noise.
  • the number of strands is relative may remain low, with preferably six, possibly seven or eight strands are used, this is also ensured that the rope remains spliceable, whereas ropes remain with a higher number of strands in practice no longer spliced can be.
  • the shaped strands can in a conventional manner by means of rollers, with the aid of Drawing dies or compressed by means of a hammer mechanism, etc. whereby the final shaping is achieved.
  • rollers with the aid of Drawing dies or compressed by means of a hammer mechanism, etc. whereby the final shaping is achieved.
  • the shaped strands in the hoisting rope in addition to a lateral slipping (in the circumferential direction of the hoisting rope) secured be, and this can be done in a particularly advantageous manner be achieved by the fact that provided within the form of strands, in cross-section substantially round core radially projecting, Material areas formed by deformation during stranding that points into the air gaps between the shaped strands protruding Form spacers. In this training, thus the Spacers easy in the course of manufacture by deformation formed by circumferential material areas of the core.
  • Trensen or support strands can be made of compact plastic, such as polypropylene or polyamide, they exist however, may also be made from processed synthetic fibers, e.g. made of polypropylene, Polyamide or polyester fibers to be produced. On It would also be conceivable here, particularly durable fibers, such as about kevlar, to use for the support strands.
  • the Formlitzen can have different deposits; for example, it is advantageous for ease of manufacture, when the trapezoidal shaped strands core inserts made of compact Plastic or made of processed synthetic fibers. As plastic materials come in turn polypropylene, Polyamide and polyester, etc. in question. For especially high Strengths can also be provided that the trapezoidal shaped strands have metallic core inserts.
  • Ropes 1 are each constructed with strands 2, the under Leaving radial air gaps 4 arranged around a core 3 around are, and instead of hitherto on ropes for Ropeways and light railways usual circular cross section one have approximately trapezoidal cross-section.
  • Figs. 2 to 5 are four different, concrete embodiments for hoisting ropes 1 with a trapezoidal cross section Formed strands 2 illustrated.
  • Exemplary plastic or synthetic fiber inserts 6 im Core 3 provided, these plastic or synthetic fiber inserts 6 each with a softer plastic coating 7 are provided.
  • each metal inserts 10 are provided to the the stranded wires 9 are arranged around.
  • the metal inserts 10 the strands 2 according to FIGS. 3 and 5 can be made of steel wires according to ⁇ NORM N 9502 or 9503 exist, but they can also be made of wires be carried out of other metals or metal alloys.
  • the stranded wires 9 themselves can be made in a comparable manner Steel wires or from wires of other metals or metal alloys be formed.
  • the trapezoidal shaped strands 2 are separated with a Drawing or rolling tool or a combination of drawing and Rolling tool produced, with an example of such a Making and compacting shaped strands, albeit in context with a triangular strand, for example in the No. 5,765,357 A is shown in a very specific form. A more detailed description of the production of the shaped strands 2 can therefore be unnecessary here.
  • FIGS. 2 and 3 are the Molded strands 2 are pressed into the plastic of the encapsulation 7, wherein between the trapezoidal shaped strands 2 material areas 11 are pushed out by the deformation. These material areas 11 form spacers for the shaped strands 2, wherein these spacers or material regions 11 radially inward Piece protrude into the air gaps 4 between the form of strands 2.
  • the shaped strands 2 are characterized inside more or less form-fitting fixed relative to the core 3, so that a mutual Rubbing or scouring the shaped strands 2 despite the presence the air gaps 4 is reliably prevented.
  • Trensen or support strands 12 present, the radially in between lie the shaped strands 2 and are stranded together with them.
  • These bridles or support strands 12 are for example also made of compact plastic or processed Synthetic fibers, similar to the "soft" core inserts 6 and 8 of the Kerns 3 or Formlitzen 2.
  • As a material for these support strands or bridles 12 and for the said "soft" core inserts 6 or 8 may be a compact plastic, such as polypropylene or polyamide, but it can also be used processed synthetic fibers, such as polypropylene, polyamide or Polyester fibers; be used.
  • the material of the core encapsulation 7 of the hoist core 3 may be a so-called lo-stretch material, for example a polypropylene, or a polyamide, polyethylene u. like.
  • the hoisting rope 1 described has a comparatively large metallic cross section and therefore high Strength or high breaking forces; nonetheless despite the relatively low number of wires (six, seven or eight - Strands) by the trapezoidal shape of the strands 2 a surface with Good roundness achievable, whereby the suitability as a hoisting rope Cable cars or city cable cars is secured.
  • the episode of well-approximated roundness of the surface is essential Reduction of the strand-induced vibrations during operation, wherein Moreover, the rolling noise is significantly reduced.
  • the shaped strands 2 are only through the air gaps 4 - at least over their significant radial extent - separated from each other, so that no deposits between the strands 2 can fall out, which pose a high accident risk in the company; nichstdestoweniger can the strands 2, with appropriate dimensioning of the air gap widths, do not scrub against each other, and all the more if through the spacers in the form of plastic material areas 11 or bridles or support strands 12 in their position relative secured to each other.
