Definitions

  • the utility model relates to rope products and can be used for the production of synthetic ropes containing a core and a sheath, which are designed to lower the load along a fixed rope, as well as in other areas.
  • a synthetic rope is known (see AS SU 727720, class D07B 1/00, 1980) containing a core in the form of polyamide threads and a braid (sheath) arranged parallel to the axis of the rope.
  • a disadvantage of the known synthetic rope in the case of using a rope to lower loads along it is the displacement of the shell relative to the core, leading to a deterioration in the operational properties of the rope.
  • a combined rope consisting of a core made of synthetic fibers and enclosed in a sheath of synthetic fibers, on top of which is an intermediate layer of soft elastic synthetic material into which steel wire strands of the outer layer of the rope are pressed (see Eurasian patent JMe 017642 B1, IPC D07B 1/02, priority 05/15/2005, applicant and patent holder: KAZAR DRATSAYLVERK SAAR).
  • a disadvantage of the known combined rope is the relative complexity of its manufacture due to the need to supplement the equipment for the usual process of manufacturing ropes with equipment for extruding the intermediate layer.
  • a rope for climbing is known (see CN106012621, application number 102016000544031 of 07/12/2016, publication number 106012621, date publication 12.10.2016, type of publication A, IPC D07B 1/04, D07B 1/16, B05B 7/12).
  • the rope for climbing is made of nylon threads and includes a core, an outer shell and an intermediate shell located between the core and the outer shell, which is an adhesive film.
  • the adhesive film is made of hot-melt adhesive and connects the core and the outer shell to each other so that there are no mutual displacements of the core and the outer shell in the rope.
  • the specified climbing rope provides increased safety when using it, since mechanical impact on the rope, leading to displacement or even complete rupture of the outer shell, does not creep along the core of the rope.
  • the disadvantage of this rope is the relative complexity of its manufacture due to the need to supplement the equipment for the normal process of manufacturing the rope with equipment for applying glue to the core of the rope, as well as equipment for heating the rope in order to transfer the hot melt into a liquid state for gluing the core and the outer shell of the rope.
  • the objective of the proposed solution is to develop a synthetic rope suitable for continuous operation under mechanical stress with the accompanying displacement of the sheath relative to the core.
  • FIG. 1 of the attached images shows the proposed synthetic rope in the context; in FIG. 2 - double-sided hook tape.
  • the synthetic rope contains a core 1, a sheath 2 and located between two double-sided hook tape 3.
  • the rope is used as follows: fix it at the top point, after which the load is lowered along the rope on the trigger device.
  • the rope is subjected to mechanical stress, which provokes the displacement of the sheath 2 of the rope relative to its core 1, while the hooks of the hook tape 3, which mesh with the core 1 and sheath 2, prevent the sheath 2 from being displaced relative to the core 1.
  • the declared synthetic rope ensures the preservation of its operational properties when used, in addition, the manufacture of the rope does not require the use of additional processing equipment, which ensures economy in its manufacture.

Abstract

Le modèle d'utilité concerne l'industrie des cordes et peut être utilisé pour la production de cordes synthétiques contenant l'âme et la gaine, qui sont soumises à des contraintes mécaniques avec un déplacement correspondant de la gaine par rapport à l'âme. La nouveauté du modèle d'utilité consiste en ce qu'entre l'âme et la gaine de la corde on a ménagé deux ou plusieurs bandes synthétiques à crochets double face. La solution technique proposée permet d'éliminer le glissement de la gaine le long de l'âme pendant le fonctionnement de la corde en préservant ainsi ses propriétés opérationnelles et assurant en même temps une économie de fabrication.
