Definitions

  • the invention relates to a pneumatic ram boring machine in which an axially reciprocated piston supplied with air by a compressed air line attached to the housing delivers its impact energy to the housing and / or its impact tip.
  • Such ram boring machines serve primarily to lay supply lines for water or electricity as well as telephone cables without having to tear open the road surface or the sidewalks. They usually have a percussion tip which is actuated by a pneumatically operated percussion piston. When the percussion tip is propelled, the percussion piston is moved back and forth in a tubular housing in that compressed air supplied through a compressed air line alternately acts on the front and rear foreheads of the percussion piston. Through openings in the rear end of the housing allow the exhaust air to exit into the earth channel created by the ram boring machine and from there to the outside.
  • ram boring machines also use lubricants such as e.g. Mineral oils or other additives are added. These additives are released as mist together with the exhaust air and pose a risk to operating personnel and the environment.
  • lubricants such as e.g. Mineral oils or other additives are added. These additives are released as mist together with the exhaust air and pose a risk to operating personnel and the environment.
  • the noise generated by most ram boring machines often exceeds the permanently harmful level of 90 dBA. This level is usually exceeded even with a ram boring machine that mainly works below the surface. In particular, if a pipe is pulled in at the same time as the ramming, considerable noise escapes because the pipe acts like a sound pipe.
  • both the compressed air directed into the muffler housing placed on the bolt-firing device and the refrigerant of the compressor flowing into the filter and damping housing are deflected radially at least once, in particular the compressed air of the bolt-firing unit being radial vented outside into the atmosphere.
  • both devices the problem of the axial supply and discharge of both compressed air and exhaust air is irrelevant when using a silencer and filter housing.
  • the invention has for its object to provide a ram boring machine which reduces some of the environmental impairments accompanying the operation of such compressed air devices.
  • an air-permeable hollow cylinder arranged in the exhaust air flow has a cylindrical passage, enveloped by a sound-absorbing and / or an oil-separating filling, for the compressed air and in its end faces opposite one another, the exhaust air coaxial with that centric passage and in countercurrent to the compressed air supplied axially through the filling exhaust air inlet holes and exhaust air outlet holes.
  • the air streams can flow axially through the hollow cylinder without deflection, so that there is an air passage which is only slightly damped by the filling but is otherwise unimpeded.
  • the hollow cylinder has a central passage, it can be pulled over the compressed air line of the ram boring machine; it can also have a concentric pipe section, for example with protruding threads for screwing with two sections of the compressed air line.
  • the hollow cylinder then fills approximately the free annular space between the compressed air line and the wall of the earth channel created by the ram boring machine, so that essentially all of the exhaust air is conditioned.
  • the hollow cylinder can also have a cable connection on at least one end face in order to be able to tension a cable between the rear end of the ram boring machine and the hollow cylinder and / or the hollow cylinder and a pulling tube.
  • the filter can also be arranged directly at the rear end of the ram boring machine or at a distance in a pipe pulled by the machine, since its outside diameter is adapted to the outside diameter of the compressed air device. In any case, it is ensured that practically no exhaust air escapes without having passed the filter.
  • the filter 1 consists of a hollow cylinder 2, the end faces 3, 4 of which each have a central circular opening 5 for a tube piece 6, which is arranged concentrically to the cylinder 2 and has a smaller diameter and a slightly greater length for pulling through a compressed air line 10 and wide re with their centers concentrically arranged to the opening 5 holes 7, 8.
  • filter materials 9, 11 for filtering and soundproofing the exhaust air flow.
  • the filter can also be arranged between two sections of the compressed air line 10, it then migrates with the compressed air line in accordance with the device advance.
  • the filter 1 is arranged in a pneumatically operated ram boring machine 12 in such a way that the compressed air reaches the ram boring machine 12 in the direction of arrow 14, then the exhaust air penetrates through the holes 7 on the end face 3 into the sound-absorbing filling 9 and then into the oil-separating filling 11 and finally emerges from the holes 8 on the end face 5.
  • the filter 1 can be arranged directly at the rear end of the ram boring machine 12 (FIG. 3), at the beginning of the earth channel 13 (FIG. 4) created by the ram boring machine 12 or in a protective tube 15 drawn by the ram boring machine 12 (FIG. 5).
  • the ram boring machine 12 is provided with a control line 16 and a pull rope 17, the hollow cylinder preferably has a corresponding, parallel axis passage, not shown in the drawing.
  • the pull rope can also be attached directly to the hollow cylinder.
  • Its outer diameter corresponds to that of the ram boring machine or that of the protective tube, so that practically no exhaust air can escape unfiltered.
  • the filter according to the invention substantially reduces the sound level of the exhaust air of 100 dBA in ram boring machines and removes oil to a high percentage from the exhaust air. This is of particular importance because ram boring machines of the type in question are mostly used in densely populated and / or busy areas for trenchless laying of supply lines.
