Definitions

  • the invention relates to an exchange conveyor helix for rock drills for conveying cuttings.
  • Rock drills of the generic type have long been known.
  • the helix that can be plugged onto the drill shank are designed as reusable parts that can be used when replacing a blunt drill head.
  • Exchange helices of this type are known for example from US-A-3 372 763, DE-A-30 44 775 or DE-A-25 43 578.
  • a known exchange coil consists, for example, of a continuous support tube, on which the helical transport shoulder is applied by welding or soldering.
  • the exchange coil consisting of the casing tube and the transport shoulder can also be produced as a cast solid part with appropriate finishing.
  • the casing tube is dispensed with, so that only the transport shoulder helically surrounds the drill shank, with free spaces between the individual helical gears.
  • the known embodiments of exchange helices have the disadvantage that they are complex to manufacture as a solid part with a casing tube and a transport shoulder and are therefore expensive.
  • the exchange spiral without a casing tube can contract when there is increased resistance in the wall friction surface during the rotary movement.
  • the invention has for its object to provide a low-cost production helix for conveying cuttings as an exchange helix, which in particular also meets the requirements of a high load capacity in operation.
  • the exchange helix according to the invention has the advantage over the known solid helices that a very inexpensive endless production is possible without machining.
  • the stability of the helix is twisted by the z.
  • a conventional DIN profile with suitable toughness can be used as the profile starting material.
  • the winding process of such a profile results in a low-vibration spiral, due to the self-winding windings.
  • the transverse webs of the profiles are formed abutting in the individual turns, so that there is an almost closed jacket tube.
  • This design results in optimal support of the individual threads against each other.
  • commercially available DIN profiles according to DIN 59051 T-profile with sharp edges
  • DIN 1024 T-profile with edges
  • DIN 1028 L-profile
  • DIN 1027 Z-profile
  • Such shapes and corresponding steel selection are particularly suitable for the manufacture of the windings of the replacement coil according to the invention without the steel tearing.
  • the exchange conveyor helix 10 shown in perspective in FIG. 1 a consists of a T-profile 11 as shown in FIG. 2, the cross bar 12 of which serves as the casing tube 13 and the vertical bar 14 of which serves as the transport shoulder 15 of the conveyor helix 10.
  • FIG. 1 b the arrangement of the T-profile 11 is shown again in section.
  • Fig. 1b four threads are arranged one above the other, which are made from a continuous T-profile 11 by helical winding.
  • the gap 16 between the individual threads is kept as small as possible in order to enable the individual threads to be supported against one another. As a result, the helix cannot contract when drilling due to the rotary movement or when increased resistance occurs in the wall friction surface.
  • a T-steel according to DIN 59051 or DIN 1024 is preferably selected as the material for the exchange helix.
  • FIGS. 3 and 4 each show a spiral cutout with an L- profile (Fig. 3) and a Z-profile (Fig. 4).
  • the jacket tube surface is formed by the leg 17 and the transport shoulder by the leg 18.
  • the helical design according to FIG. 4 with a Z-profile, with leg 19 as a tubular casing surface, intermediate web 20 as a transport shoulder and leg 21 for lateral, trough-shaped limitation of the transport surface.
