Definitions

  • the invention relates to a ram boring machine for trenchless laying of supply lines in the ground with an impact piston which is axially displaceable in a housing and is operated via a supply hose by means of a pressure medium.
  • Such ram boring machines in which the self-controlling percussion piston periodically exerts ramming strikes on a movable percussion tip or the device housing, are known, for example, from German patents 21 57 259 and 26 34 066.
  • the ram boring machines are primarily used to lay supply lines such as gas and water lines, electrical lines or telephone lines or cables under streets or sidewalks without having to rip open the pavement or sidewalks at the same time.
  • the ram boring machine moves through the soil, it displaces the soil to the side and leaves an earth channel into which a supply line can be pulled in simultaneously or later.
  • Such a ram boring machine can therefore be connected at the rear end to a coupling for fastening a pulling tube; alternatively, a pipe to be laid can also be installed pull into the earth channel using a pull rope of the ram boring machine.
  • Such short pipes which are often no longer than one meter, can either be pushed into the earth channel with a press-in unit or - as is known from German patent 26 11 677 - pulled using a steel cable.
  • the compressed air hose running through the pipe to be drawn in and coupled to the rear end of the device housing is extremely disadvantageous and requires additional, complex measures because steel and plastic pipes placed against one another at their joints be welded.
  • the compressed air hose must not lie in the pipe to be pulled in, in order not to be damaged by the heat generated during welding, and must be uncoupled and pulled out of the pipe before each welding.
  • plastic pipes are usually heated with the help of a heat shield inserted into the pipe from the inside, which must therefore have a through hole for the compressed air hose, and then pressed together.
  • the individual pipe strings or short pipes must be threaded onto the compressed air hose to avoid uncoupling the hose.
  • a replenishing press must have a hole that allows the compressed air hose to pass through.
  • the hose must also be uncoupled in order to be able to add the pressure unit.
  • the invention has for its object to avoid the aforementioned disadvantages in the trenchless laying of pipes, especially short pipe strings in the ground.
  • the device In the case of a ram boring machine with a conical head piece of the driving end of the housing, the device is easier to insert into an old pipe to be replaced, or an earth channel.
  • the head piece be designed as a connecting piece that extends over the supply hose and tapers in the direction of advance.
  • the one-piece i.e.
  • a conical headpiece which transitions seamlessly into a nozzle or is provided with a screwed-in nozzle also offers protection of the supply hose which is enclosed by the nozzle on a part length corresponding to the length of the nozzle.
  • a percussion piston which is preferably stepped and has a piston extension which extends in the direction of advance and has a plurality of control openings corresponding to control openings fixed to the housing
  • the forward and return flow of the percussion piston can be controlled in such a way that the piston always faces the hose connector on the device housing and / or the tip of the device hits and releases its impact energy there.
  • a transverse bore arranged in a constricted central section of the piston extension can preferably be connected to a longitudinal bore opening into a working space behind the piston.
  • the control openings can be connected to one another by appropriate design of the control edges in such a way that after a certain backward stroke of the percussion piston, the compressed air arrives behind the percussion piston and pushes it in the forward direction, i.e. accelerated forward again, and vice versa.
  • the supply hose can advantageously be attached to a head tube, which is enclosed by a piston jacket of the percussion piston provided with control openings and extends with a continuous air duct into a piston bore.
  • the percussion piston is in its front end position when feeding Air through the central channel of the head tube first moved to the right, ie against the direction of advance, until the control openings of the piston skirt are connected to the piston bore. Then compressed air can get through the piston bore and the control openings behind the percussion piston and initiate another work cycle in the direction of advance.
  • the ram boring machine 1 has a housing 2 in which a percussion piston 3 is axially displaceably mounted.
  • the percussion piston 3 is designed as a stepped piston and has a main piston 4 and a piston extension 6, which has a smaller diameter and extends in the direction of advance 5 of the ram boring machine 1. In the position shown, the percussion piston 3 is in its front end position.
  • a pressure medium source compressor
  • compressed air hose 7 At its front end in the forward direction 5 of the housing 2 is connected to a pressure medium source (compressor), not shown, compressed air hose 7 by means of a Hose connection 8 attached.
  • a longitudinal bore 10 penetrating the front end wall 9 directs compressed air supplied via the compressed air hose 7 to the end face of the piston extension 6; this is provided with a control head 12 which has air grooves 11 distributed around the circumference (cf. FIG. 2). Due to the compressed air acting on the end face of the control head 12, the percussion piston 3 moves counter to the direction of advance 5, ie to the right, the air enclosed in a working space 13 behind the main piston 4 escaping to the rear via air openings 14 until control edges 15 of the air grooves 11 ( see Fig.
  • the working space 13 is bounded at the rear by a cover 21 screwed onto the rear end of the housing. As soon as a pressure exceeding the counter pressure has built up in the working space 13, the percussion piston 3 is accelerated back into its position shown, the air escaping to the rear via the air openings 22 in front of the main piston 4.
  • the front end of the ram boring machine 1 is provided with an insertion cone 23 and also a screwed socket 24 which tapers in the direction of advance 5 and extends the insertion cone 23 in a funnel-like manner.
  • the nozzle 24 extends over a partial length of the compressed air hose 7 and thus represents a hose protection.
  • a pulling cable 25 inserted between the connecting piece 24 and the insertion cone 23 before the screwing of the connecting piece 24 is used to guide the ram boring machine 1 moving through an old pipe (not shown) or an earth channel (not shown); the pull cable 25 can be pulled in a target pit, for example by a winch, so that the feed of the ram boring machine 1 can also be increased.
  • an expansion socket 26 which tapers conically in the direction of advance 5, is pushed onto the housing 2 and extends with a jacket 27 to the rear beyond the rear end of the ram boring machine 1.
  • a tube can be pushed between the jacket 27 and the device housing 2 and pulled into the ground with the advance of the ram boring machine 1.
  • a pressure medium hose 107 with a hose connection 108 is attached to a control tube 28 fixed in the housing 102 at the front end of the housing 102.
  • the end of the control tube 29 facing away from the hose connection 108 is designed as a head piece 29 which engages flush in a piston bore 30 of a percussion piston 103.
  • the compressed air hose 107 is connected to the piston bore 30 via an air duct 31 which penetrates the control tube 28 centrally.
  • the piston jacket 32 sliding over or on the head tube 29 has radial control openings 33 which merge into axial air channels 34; the channels 34 lead to air grooves 111, shown in broken lines, of the percussion piston 103.
  • the piston bore 30 builds up Due to the air supplied via the compressed air hose 107 and the air channel 31, the percussion piston 103 progressively further into the closed working space 113, ie pressure moving to the right.
  • the control openings 33 are designed so that the air from the working space 113 behind the piston 103 via the air grooves 111, the axial air channels 34 and the control openings 33 unhindered to vent holes 35 in the front end wall 109 of the ram boring machine 101 and escape there into the atmosphere can.
  • a conical head piece 38 which extends over the compressed air hose 107 in the direction of advance 105 and which represents an insertion cone which is integral with a connecting piece.
  • a traction cable 125 is enclosed between the head piece 38 and the front end of the housing 102.
  • an expansion socket 126 with a jacket 127 extending beyond the rear end of the ram boring machine 101 is pushed onto the device housing 102.
