Definitions

  • the invention relates to textile traction and/or suspension means and methods for producing textile traction and/or suspension means.
  • a construction of ropes, and in particular a braided construction which is particularly suitable for large diameter ropes made of low elongation synthetic fiber materials.
  • a plurality of fibers are twisted together to form a plurality of twisted yarns, a plurality of twisted yarns are braided together to form a plurality of braided strands, and a plurality of braided strands braid together to form a large diameter braided rope.
  • the rope braided in this way has no lubricant.
  • a wire rope with plastic integrated into the rope structure is known from the publication DE 20 2015 106 536 U1 known, wherein the cable consists of wires made of metal and has a plastic insert and / or a plastic sheath containing at least one friction-reducing additive.
  • Wire ropes have a large rope mass, which significantly reduces the useful mass, especially in the case of long conveyance lengths, and can make it necessary to use lower ropes in the case of traction sheave elevators.
  • Ropes with an extruded sheath layer contain small amounts of lubricant in order to prevent sheath shifting due to the friction-reducing effect and gassing caused by the lubricant. This significantly reduces the service life compared to optimally lubricated ropes.
  • the document contains a rope with core strands and sheath strands DE 20 2010 013 519 U1 .
  • the cable has at least one sensor module for detecting elongation or rupture loads, which has at least one electrically conductive sensor element.
  • EP 2 573 257 B1 describes an approximation between a steel wire cover and a high-strength braided core component, which in turn has a braided protective cover of polyester fibers.
  • the lay and braiding angles (expressed by the ratio L/d) were adjusted so that the rigidity of the core component and sheath approach each other due to the design, in order to prevent the core component from falling in front of the steel wire sheath tears.
  • U.S. 4,321,854 discloses a textile fishing line line having a braided fiber rope as a primary load-bearing component of polyamide, fiberglass, steel, graphite or polyamide with a sheath of synthetic fiber material polyester, polyamide, polyurethane or polypropylene forming a secondary load-bearing component.
  • the primarily load-bearing core component is deliberately designed to tear under a tensile load, with this being made known to the user acoustically or tactilely or haptically by jerking so that he notices that the tensile load has reached a dangerously high value.
  • the mass fraction of the mantle is higher than that of the load-bearing core component.
  • a thinning of the rope is accompanied by a loosening of the sheath, which can be determined manually.
  • the publication also teaches attaching markings to the sheath, by means of which an elongation of the cable and/or a twisting of the cable can be detected.
  • GR 2014 0100 288 A describes a textile cordage with a safety line integrated into the interior, which is intended to prevent the two ends from being thrown around in the event of a rope break.
  • the suspension line does not take over the load-bearing function of the intact cordage.
  • JP 2014 152 429 A describes a textile arresting and safety line for people working at heights where there is a risk. It comprises a textile fiber rope as the core component and a covering layer that is also made of textile fiber material.
  • the core component and the skin layer are designed to absorb the kinetic energy of a fall.
  • the object of the present invention is to provide and produce textile traction and/or support means for use in cable drives, in which traction sheaves in particular are used, with the traction and/or support means being able to be used in an economical manner a pulling and/or carrying means having the features of claim 1.
  • the textile traction and / or support means and their manufacture are characterized in particular by the fact that they are used in cable drives in which in particular traction sheaves are used, can be made available and can be produced.
  • the textile traction and/or suspension means has a braided fiber rope as a primary load-bearing component, a cover layer on the braided fiber rope and a means on and/or in the cover layer as a secondary load-bearing component which, upon and/or after failure of the primary load-bearing Component is the load-bearing component of the textile traction and / or suspension means.
  • the breaking strength of the agent is at least 12.5% of the breaking strength of the braided fiber rope and the mass fraction of the agent is less than 30% of the mass fraction of the braided fiber rope.
  • the residual breaking force of the device is greater during and/or after failure of the braided fiber rope than the maximum permissible strand load of the textile traction and/or suspension device.
  • the conditions of the breaking forces and mass proportions are present as the initial state, especially during manufacture and thus in the new condition, and must be observed as far as possible during implementation.
  • the breaking strength of the agent is at least 12.5% and thus greater than 12.5% and less than or equal to 100% of the breaking strength of the braided fiber rope and the mass fraction of the agent is less than 30% and thus greater than 0 and less than 30% of the mass fraction of the braided fiber rope.
  • the means is formed from a combination of synthetic fibers and/or mineral fibers and/or fiber strands made of synthetic fibers and/or mineral fibers.
  • the respective fibers and/or the respective fiber strands are connected to one another by laying, by twisting, by braiding, by circular weaving or by knitting.
  • At least one sensor element for detecting the breakage of the braided fiber rope is or are located in the braided fiber rope and/or in the outer layer and/or in the middle.
  • a local force dissipation of the braided fiber rope can lead to its breakage and the sensor element implemented in it, which can be detected in this way.
  • the sensor element can also be designed in such a way that changes in mechanical and/or geometric properties of the sensor element itself can be detected.
  • the sensor element can be connected, for example, to a resistance measuring device and/or an optical, acoustic and/or electrical transit time measuring device.
  • thermal fixing of such high-strength textile fiber ropes represents a way of orienting the molecular chains of the fibers in the optimal direction of the power flow, which increases strength and stretching effects can be reduced.
  • textile fiber ropes can be heated by hot air flowing around them, in which case they are subjected to force, or they are guided through a heated medium in the state subjected to force.
  • Fibrous materials and structures made from them tend to be thermal insulators, which means that external heating can cause the rope cross-section to be heated unevenly and thus treated unevenly.
  • the thermal fixing of textile structures is therefore primarily used for flat textiles and tapes, since relatively thin cross-sections have to be heated through there.
  • High-molecular polyethylene HMPE, liquid-crystal polymer LCP or also aramides can be used as polymer materials.
  • the setting temperature corresponds to a crystalline transition peak
  • this can also mean that if the heating is not uniform, the outer areas of the rope will be heat set and the inner areas will not. In the case of large rope diameters in particular, this leads to an inhomogeneous flow of forces which, under certain circumstances, worsens the mechanical properties compared to ropes that are not thermally fixed.
  • fibers and/or fiber strands are braided with at least one substance and/or object that can be activated with electromagnetic waves and/or in an alternating magnetic field Braided fiber rope as the primary load-bearing component, the braided fiber rope covered with a monolithic cover layer, the braided fiber rope with the monolithic cover layer with electromagnetic waves and/or the alternating magnetic field for heating the braided fiber rope and the substance and/or object for thermal fixation of the braided fiber rope applied and a means applied by laying, twisting, braiding, knitting or circular weaving of synthetic fibers and/or synthetic fiber strands as a secondary load-bearing component.
  • the monolithic casing is designed in such a way that it does not shield the electromagnetic waves and/or the alternating magnetic field.
  • the fiber rope contains a substance which can be activated with electromagnetic waves and/or in an alternating magnetic field and which can be or is heated with electromagnetic waves and/or in an alternating magnetic field for the purpose of thermally fixing the fiber rope.
  • the heating does not take place from the outside in as in the prior art, but directly at the active point to be heated by heating the activatable substance.
  • the fiber rope is subjected to a force in its longitudinal direction by means of a holding and stretching mechanism in such a way that this force application is at least 1%, in particular at least 2%, in particular at least 5%, in particular at least 10%, in particular at least 15% and at most 25%, in particular at most 20% of the breaking load of the fiber rope.
  • this force application is at least 1%, in particular at least 2%, in particular at least 5%, in particular at least 10%, in particular at least 15% and at most 25%, in particular at most 20% of the breaking load of the fiber rope.
  • a preferred application of force during the thermal setting would be 10-25% of the breaking load at 3500-8750 Newtons.
  • the fiber rope when exposed to electromagnetic waves and/or the alternating magnetic field for thermal fixing of the fiber rope, the fiber rope should be subjected to at least 3500 N, in particular with at least 5000 N, in particular with at least 8000 N force is applied in its longitudinal direction.
  • at least 3500 N in particular with at least 5000 N, in particular with at least 8000 N force is applied in its longitudinal direction.
  • 25%, in particular 20% of the breaking load of the fiber rope can be taken as a basis as the upper limit of this application of force.
  • the fibers and/or fabrics and/or objects that can be activated are not water-based, since water leads to a change in mechanical properties. This can be done, for example, by incorporation in the molecular chains and gassing during jacket extrusion through steam.
  • Substances that can only be activated by electromagnetic waves and/or an alternating magnetic field are introduced into the traction and/or suspension means, which remain completely in the traction and/or suspension means even after activation.
  • the substance can advantageously be a rope lubricant. This implements another function.
  • the material is heated with electromagnetic waves and/or in an alternating magnetic field and thus used to thermally fix the fiber rope, i.e.
  • the softening of the lubricant protects the fiber rope from local overheating and the rope lubricant can be distributed between the fibers and/or fiber strands, which means that the core of the textile traction and/or suspension means is optimally lubricated, which has the effect of reducing wear.
  • the substance that can be heated with electromagnetic waves and/or in an alternating magnetic field is a rope lubricant or the elongated object is made of or with an activatable lubricant, can be achieved by applying electromagnetic waves and / or an alternating magnetic field not only heating to carry out the thermal fixation of the fiber rope, but also a protection against local overheating of the fiber rope and a distribution of the lubricant.
  • textile traction and/or suspension means can fully meet the requirements in traction drives. Applications can be in particular those in which traction sheave elevators or traction sheave winches are used. The textile traction and/or suspension means can thus be used as hoisting ropes in materials handling applications.
  • a further advantage is that the local deflection of the primary load-bearing component due to material fatigue leads to a load transfer to the secondary load-bearing component. As a result, the surface topology changes, which is visible from the outside and thus indicates that the traction and suspension device is ready for discard.
  • At least one source of electromagnetic waves with a frequency equal to/greater than 300 MHz and less than/equal to 20 GHz and/or an electromagnetic alternating field with a frequency equal to/greater than can advantageously be used to heat the braided fiber rope and/or the fabric and/or the object 300 MHz to less than or equal to 6 GHz can be used.
  • the modulus of elasticity of the fibers of the agent is smaller than the modulus of elasticity of fibers of the braided fiber rope.
  • the agent absorbs no or almost no tensile forces. This mechanical behavior is achieved through a lower modulus of elasticity of the fiber material compared to the braided fiber rope.
  • the gradient angle of the fibers and/or fiber strands of the means is greater than the gradient angle of fibers and/or fiber strands of the braided fiber rope.
  • the agent absorbs no or almost no tensile forces. This mechanical behavior is achieved through a larger helix angle (angle of lay or braiding angle) compared to the braided fiber rope.
  • the braided fiber rope has at least one substance and/or object that can be activated with electromagnetic waves and/or an alternating magnetic field.
  • the cladding layer is a monolithic cladding layer that does not shield the electromagnetic waves and/or the alternating magnetic field.
  • the object can also be a fiber yarn.
  • the braided fiber rope has at least one elongated and/or ribbon-shaped object made of or with rope lubricant and/or a substance that can be activated by electromagnetic waves and/or an alternating magnetic field.
  • the lubricant can be located inside the fiber strands and/or between the fibers and/or between the fiber strands and/or in the middle of the braided fiber rope.
  • the backing can be made of yarns with synthetic, mineral, ceramic or natural threads or metallic wires, thus storing the lubricant during the sheathing process.
  • the fibrous material and/or the material and/or at least one additive in the material has or have a relative permittivity or relative permittivities greater than five.
  • the respective substance can thus be activated electromagnetically.
  • Substances that are in the solid or highly viscous state at room temperature can be used as substances. This can be, for example, wax and fat or fibrous materials as solid lubricants.
  • additives containing metal or plastic can be used as additives. Applying electromagnetic waves to the activatable substances in the rope can thus easily lead to a targeted and defined heating of the core rope to a material-dependent temperature level of between 120°C and 230°C.
  • the monolithic jacket layer can advantageously consist of a plastic whose relative permittivity has a permittivity that is five times lower than that of the electromagnetically activatable lubricant and is therefore heated less quickly.
  • the fibers and/or the substance and/or the object has or have particles and/or bodies made of electrically conductive materials.
  • these can be particles of graphite and/or at least one metal.
  • nanotubes also known as nanotubes, can be introduced as bodies.
  • the braided fiber rope has at least one electrical conductor.
  • the textile traction and suspension means is encased with a monolithic layer.
  • the subject of the invention in a preferred embodiment is a textile traction and/or suspension means for use in rope drives, the textile traction and/or suspension means being a braided fiber rope (1) as a primarily load-bearing component, a jacket layer (2) on the braided fiber rope (1) and a means (3) on and/or in the covering layer (2) as a secondary load-bearing component, the means (3) consisting of a combination of synthetic fibers and/or mineral fibers and/or fiber strands is formed from synthetic fibers and/or mineral fibers, the respective fibers and/or the respective fiber strands being connected to one another by laying, by twisting, by braiding, by circular weaving or by mesh formation, and the means (3) at and/or after Failure of the primary load-bearing component is the load-bearing component of the textile traction and/or suspension means, and the breaking strength of the means (3) is at least 12.5% d he breaking strength of the braided fiber rope (1) and wherein the mass fraction of the agent (3) is less than 30% of the mass
  • a textile traction and/or suspension means essentially consists of a braided fiber rope 1 as a primary load-bearing component, a covering layer 2 on the braided fiber rope 1 and a means 3 on the covering layer 2 as a secondary load-bearing component.
