Definitions

  • the present invention relates to a cable with strands wound on a central core, more particularly intended to be integrated into a cable transport installation, without however being limited thereto.
  • the cable which is the subject of the present invention is thus specifically able to be able to effectively support the attachment of vehicles (cabins, seats) transporting people or goods by means of fixed or disengageable clamps, or jaws, these fasteners enclosing its surface of so as to support the weight of these vehicles and their contents, while ensuring their translation throughout the installation, without there being any slippage between the cable and the aforementioned fasteners.
  • the movement of these at constant speed can be of a nature to generate noise and / or vibrations which are harmful to the environment of the installation, as well as to mechanical strength of some of its constituent components.
  • the outer layer of a traction cable or carrier-tractor according to the most common state of the art, assembled in a helix around a core, is made up of a certain number of strands, typically from 3 to 16 strands .
  • Such a helical assembly of strands around a core necessarily generates a "valley" between each pair of adjacent strands, valleys which constitute all along the cable as many geometric deviations from an ideal envelope of cylindrical shape of the outer surface thereof.
  • each of the rollers of the installation will therefore generate a movement of the latter which can reach an amplitude of several millimeters.
  • each of the rollers of the installation will therefore be driven by a periodic oscillation movement, the frequency of which may rise, depending on the case, to several tens. Hz, or even, in some cases, several hundred Hz.
  • vibrations the generation of which is inherent in the structure of traction cables or tractor carriers according to the most widespread state of the art, although lessened by a judicious choice of lining materials for the guide rollers of the cable installation concerned, may however be likely to disturb its environment (for example: generation of noise near homes) and / or accelerate the wear or fatigue of some of its components .
  • the document FR 2 769 027 which describes a cable for a gondola comprising a central core extended by peripheral inserts between which the strands are interposed during cabling.
  • the document FR 2 769 027 emphasizes the need for thorough compaction of the cable during its manufacture, with the aim of ensuring "mutual nesting of the strands, the inserts and the central core of the cable", which directly implies a very strong pinching action of each fin between the two strands which border it, this making the manufacturing process very unstable.
  • This technical choice of a thorough compaction is also likely to cause in the short or medium term either the ejection or the complete shearing of the fins.
  • Such a thorough compacting operation is therefore very delicate and does not generally make it possible to obtain a cable of homogeneous section, the vibrations then not being reduced and the cable not having the required durability.
  • the devices of the prior art also pose a problem in terms of resistance to sliding, because they are generally not sufficiently able to withstand the vertical pressure of the clamps of the transport cabs.
  • US 2,136,865 discloses a traction cable comprising a one-piece core provided with a central core having on its periphery a series of fins and strands arranged around the core
  • the aim of the present invention is therefore to remedy these drawbacks by proposing a stranded cable making it possible to minimize or even eliminate the vibrations and noises generated by its passage over the guide rollers of an installation of the towed or teleported type, thus a method of manufacturing such a cable and a suitable core.
  • the invention relates to a cable according to claim 1.
  • a cable 1 according to the invention comprises a one-piece core 2 and a series of six strands 3, with round or preferably compacted wires, wound in a helix around this core 2.
  • one-piece denotes an element which cannot be disassembled into several sub-assemblies without being damaged.
  • the core 2 itself consists of a central core 4 provided on its periphery with six regularly spaced fins 5, the side walls of which form between them as many receiving grooves 6 of substantially circular shape.
  • the fins 5 can be made of the same material as that of the central core 4 or else of one or more materials, the modulus of which is compression is preferably less than that of the central core 4, which means that these fins will then be more easily compressible than the core 4.
  • each fin 5 is shaped in an arc of a circle, so that when the strands 3 are inserted into each of the receiving grooves 6, by temporarily deforming the fins 5, the cable 1 thus obtained has an outer casing of substantially cylindrical shape, which therefore hardly comprises any more valleys.
  • the internal diameter of the circular part of the receiving grooves 6 is chosen so as to be close to, and slightly smaller than that of the strands 3 that they are to receive so that the contact is as close as possible between the side walls of the fins 5 and strands 3, without a thorough compaction operation according to the prior art while guaranteeing obtaining a homogeneous section and a profile of very great regularity over the entire length of the cable.
  • the one-piece core 2 can be manufactured by any process suited to the nature of the material (s) from which it is made. It will preferably be made of synthetic materials, a term which here covers all thermoplastic compounds, thermosetting compounds, elastomers and vulcanizable compounds. Mention will in particular be made of polymers such as polyolefins and, in particular, polyethylene.
  • these materials can be added with fillers, so as to give them particular properties, for example resistance to UV radiation, electrical conductivity, resistance to compression, or lubrication.
  • the strands 3 may conventionally consist of an assembly of wires of different diameters wound in a helix around a central wire. They are preferably metallic and more particularly preferably made of steel. They can be individually the subject of a compacting operation, so as to increase the metal section of a cable of given diameter.
  • a core 7 according to the invention further comprises a strand 8 embedded in its central core 4.
  • This strand 8 may conventionally consist of an assembly of wires of different diameters wound in a helix around a central wire. It is preferably metallic and more particularly preferably made of steel. Its dimensioning is generally carried out in such a way that it participates in the absorption of the tensile forces transmitted by the cable, but may also have the sole purpose of ballasting it.
  • the cores according to the invention can also comprise fibers, metallic or not, inserted longitudinally in the central core 4.
  • their dimensioning is generally carried out such that they participate in the recovery of the tensile forces transmitted by the cable, but may also have the sole purpose of ballasting it.
  • the cable according to the invention can be spliced to form a closed loop by coupling the opposite ends of its strands.
  • the cable according to the invention is more particularly intended to be integrated as a pure traction cable or as a towing carrier cable in an installation for the transport of persons by cables such as a mechanical lift installation such as, for example, but of not limited to a gondola or a cable car.
  • Transport installations such as ski lifts are in fact held by a carrier-tractor cable, that is to say that the cable ensures the reach of the cabin but also its drive upwards.
  • two cable systems are available, namely one or two supporting cables and one or more traction cables.
  • the carrier cable is fixed and stretched between the departure station and arrival station of the facility and does not move.
  • the traction cable which provides traction for the cabin, is attached to the cabin trolley and forms a drive loop stretched between the two stations.
  • the cable according to the invention is capable of being used in numerous other applications such as an urban transport system, for example, and is therefore not limited to these aforementioned uses.
