Definitions
- the invention relates to a ram boring machine for the destructive replacement of buried earth Pipelines.
- Such ram boring machines are known and have radial cutting edges, that when the ram boring machine was driven, the old one that could no longer be renovated Pipe made of gray cast iron, steel or stoneware, unreinforced concrete or plastic smash.
- German Patent 40 14 775 Such a device is described in German Patent 40 14 775.
- This ram boring machine has a conical housing tip on which a Pulling rope attacks, and an expansion cone on the rear of the device. In the area of radial cutting edges are arranged in the cylindrical housing part.
- This well known The ram boring machine has continued to be relatively smashed Pipelines in soft soil have been tried and tested, but only for pipelines suitable, the clear width larger than the diameter of the housing of the Ram is.
- a drilling device is from the Swiss patent specification 680 776 A5 known in which the tip of a ram boring machine also with a smashing head is provided in the direction of advance in a cylindrical Neck section runs out and there carries a guide sleeve, so that here Overall diameter slightly less than the inside diameter of the one to be destroyed Old pipe results.
- the smashing head is thereby on the device tip fixed that a threaded rod connected to a pull rope in the Inside the device tip is welded to a plate. With the help of one the neck section located on the threaded rod can be fix the smashing head on the device tip. Like the threaded rod is inserted into the tip of the device with the welded plate and How the traction cable is connected to the threaded rod is not described.
- Vibratory drilling rig has a special head made of four clamped together Profiles with two openings for cables and two holes for Hydraulic hoses.
- the hydraulic hoses are used to carry the drill Supply hydraulic fluid as a drive means while using the Tensioning cables placed a housing in contact with the rear Should be held at the end of a shaft or the device parts held together should be. The device is moved forward using the cables; however, these attack deep inside the two-part device.
- the invention is based on the problem of a ram boring machine for destruction Replace buried piping to create a simple one Can be quickly connected with a pull rope.
- the invention consists in one Ram boring machine according to the features of claim 1.
- the smashing head can also be conical, so that its radial cutting from a diameter of the cone that is smaller than the cylindrical housing diameter is, up to a diameter that is at least equal to the diameter of the cylindrical housing part, can rise. Pipelines can therefore be shattered clear width smaller than the outer diameter of the cylindrical housing of the ram boring machine.
- the tip of the ram boring machine advantageously has an axial opening for a pull cable adapter and a cross hole for a fastening bolt the pull cable adapter, so that the opening for the pull cable adapter and the Fastening bolts are inside the head and against external influences are protected.
- the smashing head can be placed on the conical tip of the ram boring machine tighten so that there is no wear due to a loose Seat of the smashing head on the tip of the ram drill results and the impact energy acting on the device tip directly on the smashing head is transmitted.
- the eyelet has a conically widening, area adjacent to the front end of the shattering head has radial cutting, since there is the area of the eyelet on which the pull rope attacks the inside diameter of the pipeline to be broken can be adjusted and the smashing by the cutting itself tapered area of the eyelet begins. Because of the tension of the Eyelet, the smashing head and the conical device tip over the The impact energy of the ram boring machine is also on the eyelet transferred without losses.
- the radial cutting edges on the smashing head do the final Smashing the pipeline and breaking it down into small fragments When driving the ram boring machine, push it slightly to the side into the ground to let.
- each pair is diametrically opposed to each other Cutting on the tapered area of the eyelet and on the smashing head are arranged and these are aligned.
- the tapered tip 2 can made in one piece with the housing of the ram boring machine 1 or to the Housing attached; it has an axial opening 3 in the form of a Slot and a transverse bore 4 for inserting a fastening bolt 5 on.
- a likewise tapered shattering head 6 is with its tapered bore 7 placed on the tip 2 of the ram boring machine 1.
- the smashing head 6 has radial cutting edges 8 with sharpened cutting edges 9, which extend over practically the entire length of the smashing head 6, are arranged radially opposite one another and with their Cutting edges 9 approximately parallel to the conical surface of the shattering head 6 run.
- the cutting edges 9 have a bevel 10 so that the height of the Cut 8 in this area the small diameter of the smashing head 6 only slightly exceeds.
- An eyelet 13 is on a thread 14 on the free, from the smashing head 6 protruding end of the pull rod 11 screwed and braced the Smashing head 6 with the tip 2 of the ram boring machine 1.
- To a To avoid unintentional loosening of the eyelet 13 is the screwing of the Eyelet 13 with the pull rod 11 in the area of the thread 14 with an adhesive provided, 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 for not shown pull rope stuck.
- a conically widening area 18 In the area of the thread 14 there are on the eyelet 13 a conically widening area 18, the soldered or has radial cutters 19 fastened in another way.
- the Cutting edges 20 of these cutting edges 19 run essentially parallel to Outer surface of the conically widening area 18 and aligned with the radial cutting 8 on the smashing head 6.
- An old pipe 21 to be smashed has a clear width that is not much larger is as the front cylindrical portion of the eyelet 13, so that when driving the ram boring machine 1 a first smashing or at least widening the Old line 21 takes place through the radial cutting edges 20.
- the radial Cutting edges 8 on the shattering head 6 complete the shattering of the old line 21 into small pieces and work together with the conical smashing head 6 a displacement of the fragments into the pipeline 21 surrounding soil 22.
