Description

The invention relates to textile tensile and / or suspension means.

Through the publication DE 699 07 581 T2 For example, a construction of ropes, and more particularly a braided construction, which is particularly suitable for large diameter ropes made from low elongation synthetic fiber materials, is known. To this end, 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 to braid a plurality of braided strands to form a large diameter braided rope. The braided rope has no lubricant.

A wire with integrated plastic in the rope structure is by the document DE 20 2015 106 536 U1 known, wherein the wire rope 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 cable mass, which significantly reduces the payload, especially in the case of long conveyor lengths, and may require the use of sub-ropes for traction sheave elevators. Ropes with a sheath extrusion layer contain small amounts of lubricant to prevent sheath shifts due to the friction-reducing effect and gassing by the lubricant. This significantly reduces the service life compared to optimally lubricated ropes.

A rope with Kernlitzen and Mantellitzen includes the publication DE 20 2010 013 519 U1 , The cable has at least one sensor module for detecting strain or disruption loads, which has at least one electrically conductive sensor element.

The specified in the protection claim 1 invention is the object of textile tensile and / or suspension means for use in cable drives, in which traction sheaves are used in particular to provide.

This object is achieved with the features listed in the protection claim 1.

The textile tensile and / or suspension means are characterized in particular by the fact that they are available for use in cable drives, in which traction sheaves are used in particular.

For this purpose, the textile tensile and / or suspension has a braided fiber rope as a primary load-bearing component, a jacket layer on the braided fiber rope and a means on and / or in the sheath layer as a secondary load-bearing component, which at and / or after failure of the primary load-bearing Component is the load-bearing component of the textile tensile and / or suspension means. The breaking force of the agent is at least 12.5% of the breaking strength of the braided fiber rope and the weight percentage of the agent is less than 30% of the weight fraction of the braided fiber rope.

The conditions of the breaking forces and mass fractions are present in particular during production and thus in the new state as initial state and to comply with the realization as far as possible. The breaking force 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 braided fiber rope.

To realize a textile tensile and / or suspension means fibers and / or fiber strands are braided with at least one activatable with electromagnetic waves and / or in an alternating magnetic field material to form a braided fiber rope as a primary load-bearing component, the braided fiber rope coated with a monolithic jacket layer , the braided fiber rope having the monolithic sheath layer with electromagnetic waves and / or the alternating magnetic field for heating the braided fiber rope and / or the article for thermal fixation of the braided fiber rope applied and means by laying, twisting, braiding, stitching or Rundweben of Synthetic fibers and / or synthetic fiber strands applied as a secondary load-bearing component. The monolithic sheath is designed so that it does not shield the electromagnetic waves and / or the alternating magnetic field.

A realization of a further textile tensile and / or suspension means takes place by braiding fibers and / or fiber strands and at least one elongated and / or band-shaped object to form a braided fiber rope as a primary load-bearing component, wherein the object at least one with electromagnetic waves and / or a substance which can be activated in an alternating magnetic field and / or the article consists of a substance which can be activated by electromagnetic waves and / or in the alternating magnetic field and / or the article has at least one heat activatable substance as the electrical conductor, sheathing the braided fiber rope with one monolithic mantle layer which does not shield the electromagnetic waves and / or the alternating magnetic field, Subjecting the braided fiber rope to the monolithic electromagnetic wave and / or the alternating magnetic field for heating the braided fiber rope and fabric and / or article for thermally fixing the braided fiber rope and applying a composition by laying, twisting, braiding, stitching or circular weaving fibers and / or fiber strands as a secondary load-bearing component.

The activatable fibers and / or fabrics and / or articles are not water-based, since water causes the mechanical properties to change. This can be done, for example, by incorporation into the molecular chains and gasification in the shell extrusion by steam. Thus, only by electromagnetic waves and / or a magnetic alternating field activatable substances are introduced into the tension and / or suspension means, which remain completely in the tensile and / or suspension means even after activation. For this purpose, the substance may advantageously be a rope lubricant.

Due to the multi-layered rope construction, textile tensile and / or suspension means can completely fulfill the requirements in traction drives. Applications may be in particular those in which traction sheave or traction sheave winches are used. Thus, the textile tensile and / or suspension means can be used as hoisting ropes in conveyor technology applications.

Another advantage is that the local outflow of the primary load bearing component through material fatigue results in load transfer to the secondary load bearing component. As a result, the surface topology changes, which is visible from the outside and thus indicates the discard state of the tensile and suspension means.

For heating the braided fiber rope and / or the substance and / or the article can advantageously or at least one source of electromagnetic waves having a frequency equal to / greater 300 MHz to less than or equal to 20 GHz and / or an electromagnetic alternating field with a frequency equal to / greater 300 MHz to less than or equal to 6 MHz.

Advantageous embodiments of the invention are specified in the protection claims 2 to 12.

The residual breaking force of the agent is greater than the maximum allowable strand load of the textile tensile and / or suspension means at and / or after failure of the braided fiber rope according to the embodiment of the protection claim 2.

The agent is formed according to the embodiment of the protection claim 3 of a combination of synthetic fibers and / or mineral fibers and / or fiber strands of synthetic fibers and / or mineral fibers. In this case, the respective fibers and / or the respective fiber strands are connected to each other by laying, by twisting, by braiding, by circular weaving or by stitch formation.

The modulus of elasticity of the fibers of the agent is according to the embodiment of the protection claim 4 smaller than the modulus of elasticity of fibers of the braided fiber rope. The agent absorbs no or almost no tensile forces in normal operation. This mechanical behavior is achieved by a lower modulus of elasticity of the pulp compared to the braided fiber rope.

The pitch angle of the fibers and / or fiber strands of the agent is according to the embodiment of the protection claim 5 greater than the pitch angle of fibers and / or fiber strands of the braided fiber rope. The agent absorbs no or almost no tensile forces in normal operation. This mechanical behavior is achieved by a larger pitch angle (impact angle or braid angle) compared to the braided fiber rope.

In the braided fiber rope and / or in the sheath layer and / or in the middle or are located according to the embodiment of the protection claim 6 at least one sensor element for detecting the breakage of the braided fiber rope. A local power drainage of the braided fiber rope can lead to its breakage and the sensor element implemented therein, which is thus detectable. In addition, the sensor element may also be designed so that mechanical and / or geometric property changes of the sensor element itself can be detected. For this purpose, the sensor element can be connected to a resistance measuring device and / or an optical, acoustic and / or electrical transit time measuring device, for example.

The braided fiber rope, according to the embodiment of the protection claim 7 at least one activatable with electromagnetic waves and / or an alternating magnetic field substance and / or object. Furthermore, the jacket layer is a monolithic and the electromagnetic waves and / or the alternating magnetic field not shielding jacket layer. The article may also be a fiber yarn.

The braided fiber rope, according to the embodiment of the protection claim 8 at least one elongated and / or band-shaped object or with rope lubricant and / or a activatable by electromagnetic waves and / or a magnetic alternating field substance. Thus, the lubricant 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 may consist of yarns of synthetic, mineral, ceramic or natural filaments or of metallic wires, thus storing the lubricant during the coating process.

According to the embodiment of the protection claim 9, the fibrous material and / or the substance and / or at least one additive in the substance has or have a relative permittivity or relative permittivities greater than five. Thus, the respective substance is electromagnetically activated. Substances which can be used as substances are those which are solid or highly viscous at room temperature. These may be, for example, waxes and fats or fibrous materials as solid lubricants. As additives, for example, metallic or plastic-containing additives can be used. An exposure of the activatable substances in the cable with electromagnetic waves can thus easily lead to a targeted and defined heating of the core rope to a material-dependent temperature level, each including from 120 ° C to 230 ° C.

In addition, the monolithic jacket layer can advantageously consist of a plastic whose relative permittivity has one of five lower permittivity than the electromagnetically activatable lubricant and is thus heated less quickly.

The fibers and / or the substance and / or the article has or possess according to the embodiment of the protection claim 10 particles and / or body of electrically conductive materials. These may in particular be particles of graphite and / or at least one metal. As a body, for example, nanotubes, also known as nanotubes, introduced.

The braided fiber rope has according to the embodiment of the protection claim 11 at least one electrical conductor.

The developments of the claims 10 and / or 11 advantageously lead to the fact that the substance can be heated by means of an electric field. For this purpose, the braided fiber rope provided with the sheath layer can be passed through an inductor connected to a generator, so that the braided fiber rope can be heated continuously.

The textile tension and support means is encased according to the embodiment of the protection claim 12 with a monolithic layer.
