Definitions

  • the invention relates to a method and an apparatus for manufacturing a safety net.
  • Such safety nets are used in rockfall and Avalanche barriers, as a floor covering to prevent soil erosion or used for similar purposes. (See e.g. US-A-3 539 135 or US-A-1 478 720).
  • safety nets for the purposes mentioned above have been made up of individual ones Steel wire spiral ropes formed, the rope ends after looping through were connected by adjacent rings through a compression sleeve. This type of safety net has proven itself, she is however relatively expensive and complex to manufacture.
  • Safety nets composed of rings must be installed Condition, be it in an avalanche or a rockfall barrier, on the one hand absorb considerable impact forces and, on the other hand, extremely corrosion-resistant because such structures usually last for decades for example, remain on mountain slopes.
  • Safety nets for Prevention of soil erosion preferably on steep slopes, are designed to cover the floor immediately, must be able to take up large-scale landslides and withstand corrosive attacks.
  • the object of the present invention is to be achieved, a method and to provide a device for the production of safety nets with the purpose of making such safety nets inexpensive and possible easy to manufacture, the safety net should be able to elastic deformation to absorb and reduce kinetic loads.
  • a wire is fed from a bending device to a ring with the desired diameter shaped, with several turns lying flat on top of one another Diameter are formed by at least two previously manufactured rings are looped.
  • the relatively thick wire is more corrosion resistant compared to thin wires, for example of spiral wire ropes.
  • a safety net according to FIGS. 1-4 is produced in the Way that initially a number of non-contiguous rings 20a, b, c, d can be produced from a steel wire, as explained in more detail below becomes.
  • These rings 20a, b, c, d are in a suspension device lined up side by side.
  • Fig. 1 one is Bending device 15 is present, which arcuate the single wire 22 deformed.
  • Fig. 2 it can be seen that the wire arch in both the first 20a and engages in the adjacent second ring 20b.
  • Fig. 3 shows that the arch wire is formed into a circular ring, whereby several turns of the same diameter are formed.
  • Figures 5 and 6 show a device 10, by means of the rings that can be looped into each other.
  • the device 10 has a table top 11, wire feed elements 12, a subordinate Bending device 15, a shearing device 25 and wire guides 18, 19 on.
  • a longitudinal opening is approximately central in the table top 11 11 'provided, through which previously manufactured rings 20 in approximately vertical position.
  • the motor-driven wire feed elements 12 have several, preferably four rollers 13 through which the wire 22 in the direction of Arrow A is passed and at least one of them for the determination the wire feed speed of a variable-speed, Motor not shown is driven.
  • the wire arrives then between the rollers 16, 17 of the bending device 15. At least the middle roller 16 is for changing the desired one Adjustable ring diameter.
  • the wire 22 initially becomes an arc shaped and by further feed a circular ring is created.
  • the roles 16 and 17 are on opposite sides of the Wire 22.
  • the ring formed is by several on the circumference distributed guide rollers or guide pin 19 out. After education of a full circle, the wire feed is continued, so that several Windings with practically the same diameter are generated.
  • the wire will be one Shear device 25 immediately afterwards to a full extent - that is to say after the bending device 15 - cut off.
  • This out rings consisting of several turns of practically the same diameter 20 are radially distributed by a plurality of holding means 21 distributed around the circumference held together.
  • These holding means are preferably made of C-shaped Brackets per se known training, which then through Closing devices for a wire wrapping around the slotted O-shape can be deformed.
  • a ring 20 from one selectable number of loose but by holding members 21st radially held turns of a continuously wound Wire 22 formed.
  • the wire 22 is made of hot-dip galvanized round steel or stainless Steel so that it achieves the necessary corrosion resistance.
  • the ring 20 preferably has between 3 and 15 turns and The wire thickness is advantageously between 1-5 mm.
  • rings 20 of this type comprising a plurality of wire windings
  • the wire 22 is used in the formation of the nets Ring 20 looped through two previously produced rings 20a, 20b.
  • suspension devices are shown in FIG. 5 for previously produced rings that are initially not connected 20 available. These suspension devices 31 are along a shaft 32 arranged parallel to the longitudinal openings 11 'in the table top 11 runs. Each of these hangers contains two side slots 33, 34. In the suspension devices 31 are in the axial direction of the shaft 32 with a small mutual distance a plurality of previously produced Rings hung, which are each suspended in the slots 33, like this emerges from Fig. 2. These hung in the suspension device 31 Rings 20 extend transversely to those produced on the table top 11 Wrestling 20.
  • the table top 11 is horizontal, take the of the Suspension device 31 worn rings 20a, 20b, 20c a vertical Location on, i.e. one applied to the diameter of the rings 20 Main level is vertical. As shown in Fig. 2, the on the table top 11 windings generated by the bending device 15 looped through the central opening of the suspended rings 20a, 20b. After the ring 20 on the table top 11 with the desired Number of windings is provided 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, not shown Device raised.
  • the table top 11 is velvet Bending device 15, for example by a spindle 37 in the direction of Arrow C - that is, parallel to the longitudinal axis of shaft 32 - to the next Ring moved.
  • the rings 20 previously produced are then either by hand or by a device not shown in hung the slot 34 of the suspension device 31.
  • the displaced position of the bending device 15 or the table top 11 repeat the processes described above, starting with a Another ring 20 is generated, which by the ring 20b and 20c is looped through. The processes described are repeated repeated until one corresponds to the width of the network to be produced Ring number is reached. After a row with the desired number of rings was formed, the shaft 32 in the direction of arrow B by about 90 ° twisted.
  • rings 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 in one Wire diameter of 3 mm and a hot-dip galvanized steel wire.
  • An embodiment variant is that in the suspension device 31 two finished rings can be hung next to each other at the same time. Of the Ring 20 to be wound is consequently simultaneously by four vertical rings looped through. This creates two rows of rings at the same time.
  • Another variant is that several in parallel working bending devices can be arranged side by side.
