Definitions

  • Ram rigs of this type have become trenchless Laying cables in the ground or in the case of destructive Extraordinary replacement of underground pipelines reliable; they need to be reversed, for example To be able to produce blind holes or a through an insurmountable obstacle held up by the ground not having to dig out, but in reverse operation move out of the hole he has already made to be able to.
  • control sleeve Inside the control sleeve is between one Stop of the stepped tube for the supply of working air on the one hand and a collar of the control sleeve on the other a return spring that works in conjunction with over an axially parallel channel of control air supplied Control sleeve against the pressure of the working air in the Working area of the percussion piston in its forward position holds.
  • the axially movable control sleeve also has permanent Sliding contact with the inner wall of the piston. With increased Friction, as caused by pollution or If optimal lubrication does not occur, the control move back and forth because of the low reversing forces not sufficient to fix the bush axially. The same problem occurs when a self-propelled Ram drilling machine when walking through different soil layers in the Soil strained or bent.
  • control channel consists of two concentric tubes, making it radial more space is needed than if the control air is through one or more radial Drilling is supplied. This is a big one, especially for smaller devices Disadvantage, since there is hardly any space for exhaust air and supply air ducts.
  • the invention is based on the problem, in particular to avoid the disadvantages, which result from the fact that the control sleeve and the jacket of the Schtagkolben work area to be in direct contact with each other.
  • the invention proposes a ram boring machine, with a axially movable in a housing, reversible from flow to return Percussion piston with a radial working openings and a Control sleeve guided into the work space and fixed to the housing.
  • the annulus and the control sleeve can with corresponding stops be provided, the at least one of the two working positions of the control box determine.
  • the inner tube, the outer tube and the control sleeve can with each other in groups in the case of forward or reverse corresponding radial control openings his.
  • the Control sleeve under the influence of a compression spring and / or a control air line in the annular space in front of the control sleeve open in the form of a control air duct.
  • a compression spring and / or a control air line in the annular space in front of the control sleeve open in the form of a control air duct.
  • control air and the spring can also be the same Possess direction of action.
  • the Control air duct in a pressure chamber of the control sleeve and the control box is adjusted using the Control air and the compression spring on the one hand and with the help into another pressure chamber of the control sleeve incoming working air.
  • control air line runs through the guide tube 8
  • the working air or compressed air for the percussion piston instead the control air effective. If the tax can under the influence of the control air in its return position then the working air holds the Control box in the event of a leak in this position. is the control air line is depressurized and is located Control box in its forward position, then presses Working air the control box automatically in the event of a leak to its return position and the device moves from the ground.
  • the ram boring machine consists of a cylindrical housing 1 with a striking tip 2 and one with radial Control openings 3 provided percussion piston 4, in the rear part is a rear work space 5.
  • a stop ring 6 In the rear part of the housing 1 is a stop ring 6 with axially parallel ventilation openings 7 built-in.
  • the stop ring 6 projects through a guide tube 8, on the one hand with a work or not shown Compressed air hose is connected and on the other hand with its front end in the working space 5 of the percussion piston 4 dips.
  • the guide tube 8 consists of a Inner tube 9 and a shorter outer tube 10, between which is an annular space 11 with one in the work space 5 opening bore 12, for example one End bore is located.
  • the inner tube 9 has one or several radial control openings 13 and the outer tube radial Control openings 14.
  • In the annular space 11 is one axially adjustable control sleeve 15 out between the and a stop on the inner tube 9 is a compression spring 16 extends.
  • the control sleeve 15 has radial control openings 17 and a front, via the control opening 13 with the compressed air-carrying inner tube 9 related Pressure chamber 18 and a pressure chamber 19, which have a Control air line in the form of a control air duct 20 in the inner tube wall and a valve, not shown is connected to a control air source. Furthermore the control sleeve has a stop edge 21 and an inner stop collar 22 while the inner tube 9 is provided with a stop collar 23.
  • the Outer tube is also with an external recess 24 provided.
  • the rear pressure chamber 19 of the control sleeve 15 is vented and moves the over the bore 12 in front of the control sleeve and in the front pressure chamber 18 and in Working space 5 pending compressed air the control bushing 15 against the force of the compression spring 16 in the return position (Fig. 3).
  • the radial ones are aligned Control openings 13, 14, 17 of the inner and outer tubes 9.10 and the control box 15 with the result that about these control openings even then compressed air in the front working space arrives when the radial Control openings 3 of the percussion piston 4 in the area of Recess 24 are located.
  • control channel 20 into the pressure chamber 19 of the control sleeve 15 arrives, it moves under against the influence of the compression spring 16 and the control air the effect of in the front pressure chamber 18 and over the end bore 12 in the annular space 11 in front of the control sleeve Coming compressed air in the direction of advance until the stop edge 21 hits the outer tube 10 and the Forward position (Fig. 2) is reached.
  • the outer tube has an additional recess 30 with radial control openings 31, while the control sleeve 27 with a inward facing stop ring 32 and additional rear control openings 33 is provided, which in the open rear part of the annular space 11.
  • the radial bore 28 serves to keep the pressure chamber 34 running with the operating compressed air of the ram boring machine Food. Thereby, the pressure chamber 35 causes that if the control air duct 25 is vented, the control sleeve 27 is pushed into the return position.
  • the active surface in chamber 34 that is pressurized with compressed air is smaller than that of the chamber 35, which only causes a shift becomes possible. This reversal works without a compression spring 16 purely pneumatic.
  • the two exemplary embodiments differ in this from each other that in the embodiment of the 1 to 3, the control air and the compression spring 23 in work in the same direction and accordingly the control box 15 in the forward position during the advance (Fig. 1, 2) and during the return in their rear position (Fig. 3).
  • the control air acts in the exemplary embodiment 4, 5 opposite to the direction of the ram boring machine, so that the control sleeve 27 during Forward in their rearward position (Fig. 4) and during the rewind in its forward position (Fig. 5) is located.
  • the movement reversal of the ram drill causes a control air valve actuated and one opposite the percussion piston encapsulated control box from one to the other Working position is moved.
  • FIGS. 6 and 7 differs from the reversal of FIGS. 5 and 6 in that the control air through a control air hose running in the inner tube 9 36 enters the pressure chamber 35. Furthermore the control sleeve 37 has only front control openings 17, while the control sleeve 27 front control openings 17 and rear control openings 33 has. The Elimination of the rear control openings 33 leads to the fact that the control sleeve 37 when running backwards in the rear (Fig. 6) and when running forward in the front working position (Fig. 7). Because in the event of a leak in the control air hose 36 this under the influence of Working or compressed air in the inner tube 9 is moving the control sleeve 37 always in his leak Return position.
