Definitions

  • the invention relates to a ram boring machine for the destructive replacement of underground pipelines.
  • Such ram boring machines are known and have radial cutting edges which smash the old pipe made of gray cast iron, steel or stoneware, unreinforced concrete or plastic when the ram boring machine is being driven forward.
  • German Patent 40 14 775 Such a device is described in German Patent 40 14 775.
  • This ram boring machine has a tapered housing tip, which is engaged by a traction cable, and an expansion cone at the rear of the device. Radial cutting edges are arranged in the area of the cylindrical housing part.
  • This known ram boring machine has proven itself in the destruction of relatively large pipelines in soft soil, but is only suitable for pipelines whose clear width is larger than the diameter of the housing of the ram boring machine.
  • the invention is based on the problem of creating a ram boring machine for the destructive replacement of underground pipelines, with which pipelines can be used Smash with a smaller internal width than the outer diameter of the ram boring machine housing, which enables easy adaptation to the diameter of the old pipe and the diameter of the new pipe, as well as easy replacement of worn cutting edges.
  • a shattering head according to the invention is preferably placed with radial cutting edges on the conical tip of the ram boring machine, which engages the pulling rope at the tip of the ram boring machine and is protected by a cable sheath.
  • the rope sheath prevents damage to the pull rope due to fragments of the old pipe, which can easily occur, especially with brittle pipes.
  • the shattering head can therefore also be conical, so that its radial cutting edges can increase from a diameter of the cone that is smaller than the cylindrical housing diameter to a diameter that is at least equal to the diameter of the cylindrical housing part.
  • Pipelines can therefore be shattered, the clear width of which is smaller than the outer diameter of the cylindrical housing of the ram boring machine.
  • the shattering head can easily be replaced by a new one, or the shattering head can be removed and repaired.
  • the tip of the ram boring machine can have an axial opening for a pull cable or a pull cable adapter and a cross hole for a fastening bolt of the pull cable or pull cable adapter, so that the opening for the pull cable or pull cable adapter and the fastening bolts lie within the shattering head and are protected against external influences are.
  • the shattering head can be tightened on the conical tip of the ram boring machine so that there is no wear and tear of a loose fit of the shattering head on the tip of the ram boring machine and the impact energy acting on the device tip is transmitted directly to the shattering head.
  • the eyelet has a conically widening area with radial cutting edges, which is adjacent to the front end of the shattering head, since the area of the eyelet, on which the pulling rope acts, adjusts to the inside diameter of the shattering pipe can be adjusted and the shattering already begins by the cutting on the conically widening area of the eyelet. Due to the tensioning of the eyelet, the shattering head and the tapered device tip via the drawbar, the impact energy of the ram boring machine is also transferred to the eyelet without losses.
  • the radial cutting edges on the shattering head result in the final shattering of the pipeline and the dismantling into small fragments, which can be easily pushed sideways into the ground when the ram boring machine is being driven.
  • a pair of diametrically opposed cutting edges are arranged on the conical region of the eyelet and on the shattering head and these are aligned with one another.
  • the cutting edges of the cutting edges on the tapered area of the eyelet and on the smashing head can also be aligned in a conically widening manner and the cutting edges on the front end of the smashing head can be chamfered to a height that is smaller than the rear diameter of the conical area of the eyelet.
  • the rope sheath preferably consists of at least one elastic sleeve surrounding the rope, which can be surrounded by a guide sleeve.
  • the sleeve and the guide sleeve are preferably slotted axially parallel so that they can be effortlessly brought onto the pull rope.
  • the rope cover can be on the pull rope be fixed with the aid of a rope clamp, which prevents the rope sheath from moving on the pull rope.
  • the joints between the sleeves and the sleeves should be axially offset from one another.
  • the tapered tip 2 can be made in one piece with the housing of the ram boring machine 1 or attached to the housing; it has an axial opening 3 in the form of a slot and a transverse bore 4 for inserting a fastening bolt 5.
  • a likewise conical shattering head 6 is plugged with its conical bore 7 onto the tip 2 of the ram boring machine 1.
  • the shattering head 6 has radial cutting edges 8 with sharpened cutting edges 9, which extend over practically the entire length of the shattering head 6, are arranged radially opposite one another and with their cutting edges 9 run approximately parallel to the conical surface of the shattering head 6.
  • the cutting edges 9 have a bevel 10, so that the height of the cutting edges 8 in this area only slightly exceeds the small diameter of the shattering head 6.
  • a pull rod 11 engages through an axial bore in the shattering head 6, the eye 12 of which is held in the axial opening 3 of the conical tip 2 by means of the fastening bolt 5.
  • An eyelet 13 is screwed onto a thread 14 on the free end of the pull rod 11 protruding from the shattering head 6 and braces the shattering head 6 with the tip 2 of the ram boring machine 1.
  • the eyelet 13 is screwed provided with the pull rod 11 in the area of the thread 14 with an adhesive which, when heated, allows the threaded connection to be released.
  • the eyelet 13 also has an axial opening 15 in the form of a slot and a transverse bore 16 through which a fastening bolt 17 can be inserted for a traction cable (not shown).
  • a conically widening area 18 on the eyelet 13 which is soldered in or on otherwise attached radial blades 19.
  • the cutting edges 20 of these cutting edges 19 run essentially parallel to the outer surface of the conically widening region 18 and are aligned with the radial cutting edges 8 on the shattering head 6.
  • An old pipe 21 to be smashed has a clear width which is slightly larger than the front cylindrical region of the eyelet 13, so that when the ram boring machine 1 is driven, the old pipe 21 is first smashed or at least widened by the radial cut 20.
  • the radial cutting edges 8 on the shattering head 6 complete the shattering of the old line 21 into small pieces and, together with the conical shattering head 6, cause the fragments to be displaced into the soil 22 surrounding the pipeline 21.
  • the impact energy of the ram boring machine 1 is transmitted without play and without losses to the shattering head 6 and the eyelet 13, so that rapid work during the destructive replacement of installed pipelines can be carried out results, but and an easy disassembly of the smashing head is possible.
  • the pull rope ends in a loop through which the fastening bolt 5 engages, with which the pull rope is fastened directly to the tip 2 of the ram boring machine.
  • the smashing head 6 forms forward a guide mandrel 29 with radial cutting edges 8 and with a longitudinal slot into which an insert strip 23 engages. This insert is welded to a piece of pipe 30 through which the pull cable 28 extends.
  • Guide sleeves 24 are arranged in front of the guide mandrel 29 and are fixed on the pull cable 28 with the aid of a cable clamp 27.
  • Elastic sleeves 25 are located between the guide sleeves 24 and the pull rope 28.
  • the rope clamp 27 and the interior of the guide sleeves 24 are protected by a sealing cone 26.
  • the guide sleeves 24 with the elastic sleeves 25 practically form a flexible extension of the guide mandrel 29.
  • the cable sheath consisting of the elastic sleeves 25 and the guide sleeves 24, the cable clamp 27 and the sealing cone 26 can of course also be used together with the pull cable adapter 11, 12, 13 of FIG. 1.
