Definitions
- the invention relates to a steel wire strand rope according to the preamble of claim 1.
- the aim of wire ropes is to have the smallest possible diameter.
- Several have an effect on these deposits Force components with a partly changing direction of force, in particular Compressive, bending and torsional forces.
- German laid-open specification DE-A-31 49 783 - of which in the preamble has run out - shows a wire rope with several around a round one Core rope strands arranged around. There is one between each strand flexible insert element arranged. The head of these insert elements is curved and the middle part is adapted to the circumference of the wire rope. The base of these insert elements each has a concave curvature and lies against the core rope, which is round in cross section. Two wire-shaped Reinforcing cores are integrated in the insert elements.
- a textile originates from the German utility model DE-U-90 10 258 Surface sheet for reinforcing plastic parts. Doing so low elongation (crimp) in both warp and weft directions is aimed for.
- the object is to be achieved, the center piece of this Reinforcing the plastic insert so that it is used in the manufacture of the rope helical deformation and the high stresses that occur during operation can withstand and the rope has a long service life Has.
- carbon fibers for the insert plastic material has the flat insert material designed as a fabric Advantage that it is attached to the most stressed areas and can be integrated into the insert material, with it this is inextricably linked. This is the inseparable connection that the reinforcement fabric together with the material the insert is extruded into one unit.
- the long lifespan of the rope is in addition to the fabric insert supported by the fact that the foot parts of the inserts on the foot part each have one Have a wedge shape, which results in an improved flexibility of the rope, so that the compensating displacements that are unavoidable when bending a rope the wire strands can take place more easily and thereby the force concentration the strands are better distributed on the inserts.
- the steel wire stranded rope 1 shown in Fig. 1 with a circular Perimeter 14 contains six helical wire strands 2. Between There are two adjacent wire strands 2 made of plastic existing insert 4. These inserts 4 each have a wedge-shaped Foot part 8 with an outward opening angle of 60 °, one Headboard 6 and one in between horizontal web-shaped middle part 7.
- the foot parts 8 each contain an inclined surface 15 on both sides to form a Wedge shape.
- the foot parts 8 lie around a free center 12 against each other.
- the cross sections of the head or foot part 6, 8 are thickened over the central part 7.
- the middle part 7 contains Cross-section seen - two concave arches facing each other 9, the radius of which corresponds to the circumferential radius of the wire strands 2. Two adjacent wire strands 2 are thus against the arched middle part 7 and are spaced from each other by this.
- the fabric preferably consists of Plastic fibers, made of glass fibers or natural fibers.
- the inserts 4, 4 ' preferably consist of an extruded one Plastic band profile.
- As material for the inserts 4, 4 ' especially glass fiber reinforced epoxy vinyl resin or Suitable for polyethylene.
- Tissue insert 16 ' is in the plane of symmetry of the insert 4'.
- the fabric insert 16 ' is shorter than the total height of the insert.
- the fabric could also be and / or the foot part can be wrapped.
- the reinforcement fabric 16 is extruded together with the material of the insert, so that an indissoluble unit is created.
- the inserts 6 run helically together with the wire strands.
