Definitions

  • the invention relates to a synthetic fiber rope with a plurality of ropes extending at a distance from each other and a common cable sheath, z. B. for use in an elevator installation, according to the preamble of patent claim 1.
  • Running ropes are an important, heavily used machine element in conveyor technology, especially in elevators, in crane construction and in mining. Particularly complex is the stress of driven ropes, as used for example in hoists.
  • the car frame and a counterweight are connected to one another via a plurality of steel strand cables.
  • the ropes pass over a traction sheave driven by a drive motor.
  • the drive torque is impressed under frictional engagement with the respective rope section resting on the traction sheave over the wrap angle.
  • the cables experience tensile, bending, compressive and torsional stresses.
  • the relative movements caused by the bending over the sheave cause friction within the rope structure which, depending on the lubricant concentration, can have a negative effect on the rope wear.
  • the resulting primary and secondary stresses have a negative influence on the rope condition.
  • High-strength synthetic fiber ropes for example of aromatic polyamides, especially aramids, with highly oriented molecular chains meet these requirements better than steel ropes, but have a lower transverse strength.
  • the synthetic fiber rope comprises two parallel ropes, which are connected to each other via a cable sheath.
  • the synthetic fiber rope according to EP 1 061 172 A2 achieves a longitudinal strength substantially by the properties of the two parallel ropes.
  • the cable sheath prevents twisting and changes in the rope structure.
  • the cable sheath serves as insulation (protective effect) and it has a high coefficient of friction.
  • a weak point can, depending on the application and field of application of the web of such a synthetic fiber rope according EP 1 061 172 A2 be.
  • a weak point can, depending on the application and field of application of the web of such a synthetic fiber rope according EP 1 061 172 A2 be.
  • WO 98/29327 is a flat rope made of synthetic fibers known.
  • the load-bearing structure is formed by ropes that are parallel next to each other at a certain distance and are covered by a jacket.
  • This jacket is provided on the frictional with the drive pulley forming side with a coating to improve its frictional and Abnönungseigenschaften.
  • the invention aims to further improve the known synthetic fiber ropes in order to avoid inter alia a web break.
  • FIG. 1 hangs a guided in a slot 1 cabin on a supporting inventive plastic rope 3, which preferably comprises aramid fibers and which runs over a connected to a drive motor 4 traction sheave 5.
  • a cable end connection 6 to which the plastic cable 3 is attached with one end.
  • the each other end of the plastic rope 3 is fastened in the same way to a counterweight 7, which is also guided in the shaft 1.
  • 1: 1 suspension which is characterized in that the plastic rope 3 according to the invention is curved in one direction only because it only rotates about a single traction sheave 5, without being deflected by other discs, as is the case with a 2: 1 suspension, for example.
  • the low weight of plastic ropes offers the advantage that in elevator systems the usual balancing ropes can be omitted partially or completely. Compared to conventional steel cables, this can increase the maximum lifting height of an elevator installation or increase the maximum permissible load with the same rope dimensions.
  • a compensating rope can also be provided despite the use of lightweight plastic ropes.
  • Such a compensating rope is then connected in a similar manner with its first end at the lower end of the car 2, from where the compensating rope leads, for example via deflection rollers placed on the shaft bottom 10, to the counterweight 7.
  • a first synthetic fiber rope 3 for use in an elevator installation is in FIG. 2 shown.
  • the synthetic fiber rope 3 comprises at least two ropes 14 and 15 of synthetic fiber strands 20, 22, 24, and 20, 21, 23, which are designed for the absorption of force in the longitudinal direction.

  • the two-layer parallel stranded cables 14, 15 receive a nearly cylindrical outer contour.
  • the entire outer circumference of the cables 14 and 15 of the cable sheath 17 of plastic material is wrapped.
  • plastic materials are particularly suitable as cable sheath: rubber, polyurethane, polyolefin, polyvinyl chloride or polyamide.
