Definitions

  • the invention relates to a method and a device for producing a safety net.
  • Such safety nets are used in rockfall and avalanche barriers, as a floor covering to prevent soil erosion or for similar purposes.
  • safety nets for the above-mentioned purposes have been formed from individual steel wire spiral ropes, the rope ends being connected by a compression sleeve after looping through adjacent rings. Although this type of safety net has proven successful, it is relatively expensive and complex to manufacture.
  • the object of the present invention is to provide a method and a device for producing safety nets with the purpose of producing such safety nets inexpensively and as simply as possible, the safety nets being able to absorb and reduce kinetic loads by means of elastic deformation .
  • a supplied wire is formed by a bending device into a ring of the desired diameter, a plurality of windings of the same diameter lying flat on one another being formed, which are looped through at least two previously produced rings.
  • the relatively thick wire is more resistant to corrosion compared to thin wires, such as spiral wire ropes.
  • 1-4 is produced in such a way that a number of non-contiguous rings 20a, b, c, d are initially made from a steel wire, as will be explained in more detail below becomes.
  • These rings 20a, b, c, d are lined up side by side in a hanging device.
  • a bending device 15 is present, which deforms the individual wire 22 in an arc shape.
  • 2 shows that the wire arch engages both in the first 20a and in the adjacent second ring 20b.
  • 3 shows that the wire arch is formed into a circular ring, with several turns of the same diameter being formed.
  • the bending device 15 is moved laterally to the next ring, whereupon the process described is repeated. These processes are repeated over the intended width of the safety net.
  • a next row of rings is connected in an analogous manner to the previously produced row of rings.
  • the motor-driven wire feed elements 12 have a plurality, preferably four rollers 13, through which the wire 22 is guided in the direction of the arrow A and at least one of which is driven by a variable-speed motor, not shown, for determining the wire feed speed.
  • the wire then passes between the rollers 16, 17 of the bending device 15. At least the middle roller 16 is adjustable to change the desired ring diameter.
  • the wire 22 is initially formed into an arc and a circular ring is formed by further feed.
  • the rollers 16 and 17 are located on opposite sides of the wire 22.
  • the ring formed in this way is guided by a plurality of guide rollers or guide pins 19 distributed over the circumference. After forming a full circle, the wire feed is continued so that several turns with practically the same diameter are generated.
  • the rings 20a, 20b, 20c carried by the suspension device 31 assume a vertical position, ie one in diameter the main plane of the rings 20 runs vertically.
  • the windings generated on the table top 11 by the bending device 15 are looped through the central opening of the suspended rings 20a, 20b.
  • the ring 20 is provided on the table top 11 with the desired number of windings and held together radially with holding members 21 is, this lying on the table top 11 ring 20 either by hand or by a mechanical device, not shown.
  • the table top 11 together with the bending device 15 is displaced, for example by a spindle 37 in the direction of arrow C - that is, parallel to the longitudinal axis of the shaft 32 - to the next ring.
  • the previously produced rings 20 are then hung in the slot 34 of the suspension device 31 either by hand or by a device, not shown.
  • the processes described above are repeated, with a further ring 20 initially being produced, which is looped through the rings 20b and 20c. These processes described are repeated several times until a number of rings corresponding to the width of the network to be produced is reached.
  • FIG. 7 shows a ring 20 consisting of several full turns.
  • a preferred embodiment of rings 20 suitable for safety nets has a diameter of about 250-300 mm with 7 turns with a wire diameter of 3 mm and a hot-dip galvanized steel wire.
