Definitions

  • the invention relates to a method for producing a rope.
  • EP 2 441 723 A1 describes such a procedure. Fiber strands formed from fiber bundles are coated with a resin, the fiber strands are then twisted together so that the resin is arranged on the fiber strands that have been twisted together, and wire strands are stranded on the resin.
  • the invention is based on the object of further developing the method of the type mentioned in such a way that ropes of relatively low weight with improved mechanical properties can be produced.
  • this object is achieved in that fiber bundles to form fiber strands are covered with a liquefied matrix material in front of and/or at a stranding point and are embedded in the liquefied matrix material during stranding, by means of the fiber strands a fiber core of the rope is formed, the matrix material of the fiber strands after the stranding and before stranding the fiber strands, and after the matrix material has solidified to form the fiber core, the fiber strands are immediately stranded together without further occupancy.
  • a fiber core can be produced in a simple manner, the fiber bundles of which are embedded, preferably completely, in the matrix material and are therefore protected against breakage.
  • the process is simplified considerably.
  • the fiber bundles are simply embedded in the matrix material during the production of the fiber strands.
  • the fiber strands can be wound after the matrix material has solidified using the conventional stranding processes and the conventional equipment provided for this purpose.
  • the method allows the fiber core to be produced with a relatively large diameter and with a relatively more complicated structure, which cannot be formed or can only be formed with great effort when stranded within the container.
  • the method according to the invention has the advantage that the handling of the fiber strands is significantly easier and that the fiber core produced has improved mechanical properties due to the embedding of the fiber bundles. Since the matrix material protects the fibers or wires, connects them to one another and transfers the forces that occur to them, higher numbers of bending cycles can be achieved.
  • the matrix material is expediently formed by a thermoplastic, which is heated to liquefy and cooled to solidify.
  • thermoplastic is expediently used as the matrix material.
  • polypropylene polycarbonate, polyamide, polyethylene or PEEK are possible.
  • the fiber bundles are expediently sprayed with the matrix material or, as in a particularly preferred embodiment of the invention provided, immersed in the liquefied matrix material before and/or at the stranding point.
  • the fiber bundles are used, for example as in WO 2012/107042 described, moved through a, preferably heatable, container for receiving the liquefied matrix material, which encloses the fiber bundles before and, if necessary, at the stranding point.
  • the container or the spray device is expediently connected to an extruder, by means of which the matrix material is liquefied and moved to the spray device or into the container.
  • the fiber strands are heated during and/or after they have been stranded to form the fiber core in such a way that the matrix material of at least some of the fiber strands, preferably all of the fiber strands, softens, connects to the matrix material of the other fiber strands and the fiber strands are then cooled to form a material bond with one another, preferably in air or in a cooling liquid.
  • a homogeneous composite fiber core is formed, which has improved mechanical properties compared to loosely twisted fiber strands.
  • the process makes it possible to produce such composite fiber cores with large numbers of fiber strands that are cohesively connected to one another.
  • the fiber strands are expediently stranded in parallel or layered.
  • the fiber strands When stranding in layers, the fiber strands can be stranded in different lay directions to influence the torque that occurs when the rope is loaded. This makes it possible to create a fiber core that itself has little or no rotation. However, it is also conceivable to specifically provide the fiber core with a specific torque in order to adapt this to a torque caused by the outer wires or outer strands, e.g. in order to create a rope that is generally low-torsion or rotation-free.
  • the rotation property of the rope is less than or equal to a rotation of the rope of 36 ° per rope length of 1000 d when lifting a load corresponding to 20% of F min , particularly preferably less than or equal to a rotation of the rope of 3.6 ° per rope length of 1000 d when lifting a load corresponding to 20% F min .
  • the fiber core can be constructed in all conceivable rope arrangements.
  • Particularly suitable rope arrangements are Standard Seale, Filler, Warrington, Warrington - Seale, Seale - Seale, Seale - Filler, Seale - Warrington, Seale - Warrington - Seale.
  • the method according to the invention makes it possible to strand the fiber strands to produce the fiber core in the same direction, in which the fibers in the fiber strands and the fiber strands in the fiber core are twisted in the same direction.
  • the inventor has recognized that such a stranding, which was previously not possible because the fiber strands would have wound up in parallel when stranded and accordingly the fiber strands would have lost their structure during stranding, can be achieved by means of the present method, in which the fiber bundles are passed through the matrix material in held by the fiber strand structure.
  • Stranded with equal beat Fiber strands generate a greater torque when the rope is loaded than fiber strands stranded in a cross lay.
  • each fiber strand depending on the required torque generated by the respective fiber strands, it can be selected whether the fiber strands are stranded in a straight lay or a cross lay.
  • the fiber strands from the fiber bundles can be twisted clockwise (Z-lay) or counterclockwise (S-lay) and, as required, the respective fiber strand layer made of fiber strands can be stranded in a Z-lay or S-lay can.
  • a sheath is provided on the fiber core.
  • the casing is preferably formed from the matrix material, but can also be formed by another substance that connects to the matrix material or adheres to it in such a way that such large forces are transmitted between the fiber core and the casing through the connection or adhesion formed in each case can be ensured that the connection or adhesion holds when the rope is under load.
  • the material expediently has material properties similar to those of the matrix material; it is preferably made from the same class of plastics. If the sheathing is formed from the matrix material, such an amount of matrix material can be arranged in the fiber strands during the production of the fiber strands that a layer of the matrix material forms on the fiber core when heated during the stranding of the fiber core. Alternatively, the coating can also be applied in an additional operation.
  • the sheathing is preferably provided with sufficient thickness to embed the wires or the wire strands at least in sections.
  • the sheathing can be provided with such a thickness that at least the wires or wire strands of inner layers of the rope are completely embedded in the sheathing.
  • the sheathing can also be provided with such a thickness that outer layers of the wires or wire strands lie completely within the sheathing, so that the sheathing closes off the rope from the outside.
  • the embedding also creates a positive connection between an outer layer of the strand or rope formed by the wires or the wire strands and the fiber core.
  • the wires or wire strands are directly after stranding Fiber core stranded on the fiber core during a period in which the matrix material is still soft.
  • the wires or the wire strands are preformed on the fiber core before stranding, preferably in or approximately into a healing shape, which they assume in the finished rope.
  • the ropes made with the preformed wires or wire strands have lower or no internal stresses. They are cut-resistant, i.e. the wires or wire strands do not spread when the rope is cut.
  • the pre-shaping proves to be particularly advantageous if the rope only has a single layer of wire strands, since the wire strands in this structure exert a particularly large force on the fiber core and this can be significantly reduced by the pre-shaping.
  • the preforming of the wire strands can also be advantageous if the wire rope has two or more of the wire strand layers.
  • twisted bundles 2 of fibers made of, for example, aramid or polyethylene are first twisted using the method in Fig. 1
  • Stranding device 9 shown is stranded into a fiber strand 3.
  • the fiber bundles 2 are guided by means of a rotatable stranding basket 10 to a stranding point 4, where they are wound into the fiber strand 3.
  • Coils (not shown here) on which the fiber bundles 2 are wound are arranged on the Verlitzkorb 10 in a manner known per se are.
  • the fiber bundles 2 are continuously unrolled from the spools while the strand basket 10 rotates.
  • the fiber strand 3 is pulled away from the strand point 4 by means of rollers 16 and rolled up onto a drum 17 for further use.
  • the fiber bundles 2 are surrounded at the twisting point 4 by a container 11, to which thermoplastic material, for example polypropylene, can be fed via a heatable line 14 from an extruder 13.
  • the container 11 is provided on its side facing the Verlitzkorb 10 with a rotatable side wall 18 which has a plurality of openings 19 through which the fiber bundles 2 can be guided into the container 11.
  • a web 12 which is rigidly connected to the Verlitz basket 10
  • the rotatable side wall 18 is taken along by the Verlitz basket 10 when the Verlitz basket 10 rotates.
  • a fiber bundle 2 which forms a strand core in the fiber strand 3, can also be guided into the container 11 through the web 12.
  • a further opening is provided through which the fiber strand 3 formed from the fiber bundles 2 can be moved out of the container 11.
  • the opening has a diameter and a shape that corresponds to the diameter and shape of the fiber strand 3 to be formed.
  • the fiber bundles 2 are continuously twisted together at the strand point 4 in the required number, arrangement and size or in the required structure as the strand basket 10 and the movable side wall 18 rotate.
  • the polypropylene is continuously supplied to the container 11 in liquefied form. This covers the fiber bundles 2 before and during the stranding, so that the fiber bundles 2 are embedded in the fiber strand 3 in the thermoplastic.
  • the fiber strand 3 After the fiber strand 3 emerges from the opening of the container 11, it is cooled in a water bath 15 or simply in air in order to cool and thereby solidify the thermoplastic, and then rolled up onto the drum 17.
  • fiber cores 6 of any structure can be produced using the conventional stranding devices by parallel stranding or layer stranding of the fiber strands 3, for example in accordance with the general formation law for spiral ropes mentioned above or in the rope arrangements mentioned such as Seale, Filler, Warrington, etc.

  • the fiber strands 3 are heated in front of, at and/or behind the stranding point 21 in such a way that the thermoplastic in the fiber strands 3 becomes so soft that it fuses with the respective other fiber strands 3 and, after cooling, forms a one-piece fiber core 6 forms.
  • the fiber strands 3 can be heated either when individual or each of the fiber strand layers 31, 32 are stranded or only when the last fiber strand layer 32 is stranded (cf. in Fig. 4 rope shown in cross section).
  • wire strands 7 are stranded and a rope 1 according to the invention is formed.
  • the wire strands 7 are preferably stranded on the fiber core 6 as long as the thermoplastic 5 is still soft.
  • the wire strands 7 then press into the thermoplastic 5, are embedded in it and a positive connection is formed between a wire strand layer 71 lying directly on the fiber core 6 and the fiber core 6.
  • the wire strands 7 can be stranded when the thermoplastic 5 of the fiber core 6 has already solidified. The wire strands 7 then only rest on the fiber core 6.
  • the wire strands 7 can be preformed before they are stranded, preferably in or approximately into the helical shape that they assume in the rope 1 when it is finished. This allows the rope 1 to be produced with lower, if necessary even without, internal stresses.
  • thermoplastic 5 When producing the fiber strands 3, so much thermoplastic 5 can be provided in the fiber strands 3 that when the stranded fiber core 6 is heated, a sheath 8 made of the thermoplastic 5 is formed on the fiber core 6, in which wire strands 7 can be embedded.
