Definitions
- the invention relates to a method for peeling off adhering to a surface Explosives with the help of an abrasive.
- the object of the invention is to provide a method that an effective, yet gentle cleaning of explosives contaminated surfaces entirely or largely allowed without the use of water.
- air or an inert gas is used as the blasting agent used to detach explosives attached to a surface. It has been shown that when explosives are washed into sewer pipes formed explosive crusts with the help of compressed air can be detached from the pipe wall, so that there is no risk of explosion consists. The detached explosives are removed with the help of compressed air immediately blown away and can be caught in a grass catcher, for example or be sucked off with the help of a suction device. Through the constant supply of compressed air also ensures a high air exchange and thus the formation of explosive gas-air mixtures is avoided.
- the gaseous blasting medium is a solid blasting medium, for. B. Add dry ice or dry snow.
- the cleaning effect is increased on the one hand by the abrasive effect of the particles from dry ice or dry snow and on the other hand by an embrittlement effect due to the low temperature of the dry ice (-76 ° C).
- the sublimation of the dry ice into gaseous CO 2 automatically creates an inert atmosphere and thus prevents the risk of explosion. Since the blasting agent escapes as a gas, there is no need to separate the blasting agent and explosives. A possible static charge of the blasting agent can be avoided by suitable earthing measures, in particular by earthing the blasting nozzle used and possibly the associated units.
- explosives which can be ignited by pressure, such as TNT, it may be advisable to monitor the pressure in the work area and, if a certain limit pressure is exceeded, to interrupt the supply of the blasting medium or to increase the suction capacity.
- a combined process would also be conceivable for ammunition preparation, in the first step only with the gaseous blasting medium is worked and then in a second step with a post-cleaning Dry ice or dry snow is applied to the adhesive coating of the ammunition case remove stuck explosives.
- ammunition preparation is much more energy-efficient than conventional ones Rinse the sleeves with a high pressure water jet. Calculations show that only about 1 to 10% of the previously used energy are required. In addition, the elaborate is not necessary Separation of water and explosives.

- a ball mounted in a bearing pan can be provided, which also can roll in the circumferential direction on the pipe wall.
- the contaminants detached from the pipe wall are removed by the rubber sleeve 38 caught and passed into the catcher 40.
- the bead 46 prevents the solid particles from falling out of the collecting basket.
- the outer diameter of the housing 42 is significantly smaller than the inner diameter of the sewer pipe 12 so that the housing 42 does not match the remains of explosives sitting directly on the pipe wall. In In practice, the grass catcher can be considerably longer than is shown in the drawing, so that a larger amount of impurities can be included.
- the tubular housing 42 of the collecting basket can consist of several tubular segments consist of ball joints, flexible bellows and the like are hinged together. In this case it is possible to determine the length of the grass catcher and thus its capacity to enlarge considerably, and yet the grass catcher can articulated connection of the individual segments from a relatively narrow Shaft are inserted into the sewer pipe 12.
- the collecting basket 40 can also be made independently of the frame 14 the sewer pipe 12 can be movable.
- the collecting basket a separate pull rope can be provided, which on the bracket 36 of the Frame 14 is deflected and forms a closed loop, so that the The grass catcher is transported alone to the shaft and back into the after emptying Working position can be brought.
- the Traction cable 38 By suitable tension of the Traction cable 38, the grass catcher is held approximately in the middle of the sewer pipe, so that it does not drag over the pipe walls contaminated with explosives.
- the grass catcher can of course also be similar to the frame 14 be provided on the outside with rollers.
- the rubber sleeve 48 is relative soft, so that none between this rubber sleeve and the explosives high friction occurs.
- the rubber sleeve Although relatively flaccid due to the discharge from the nozzle 28 Compressed air kept in tight contact with the pipe wall, so that the detached Remnants of explosives can be reliably collected.
- the frame 14 and the collecting basket 40 with one shared or each with its own travel drive.
- a vacuum suction device can also be used instead of the collecting basket 40 or a pump device for conveying away the detached material his.
- the nozzle tube 24 is angled and eccentric is mounted in a rotatable hollow shaft, it is in another embodiment for example, it is also possible to make the lance tube 24 straight and attached to a rotating shaft at an angle to the pipe axis.
- the lance tube can also be gimbaled in the middle be so that the nozzle 28 is moved along the tube wall can by rotating the rear end of the lance tube becomes. If the lance tube also axially in the gimbal is displaceable, both the radius described by the nozzle Circular path and the angle of attack of the nozzle relative to the pipe wall can be varied continuously.
- the function of the support roller 30 can in these cases can also be taken over by a rotatable ring that is coaxial on the nozzle 28 is seated.
- FIG. 2 A modified exemplary embodiment of the robot 10 is shown in FIG. 2.
- the frame 14 is a self-propelled, motor-driven Trolley trained.
- the hollow shaft 18 is rigid in this case the frame 14 held and protrudes forward from the frame.
- the roles 16 of the frame are designed here as interchangeable wheels, so that by changing the wheel diameter or the wheelbase the central axis the hollow shaft 18 can be centered on the axis of the sewer pipe 12.
- a fork-shaped Turret 50 mounted in which a pivotable about a transverse axis 52 Swivel head 54 is mounted.
- the air lance 26 is in this case through a relatively short piece of pipe that forms in the swivel head 54 is attached.

- One known as such Generator 64 for dry ice pellets is stationary outside the sewer pipe 12 arranged and via a line 66 to the compressed air hose 32 or a supply line for this, so that the high Pressure fed blasting medium (gas) dry ice pellets in each desired dosage can be added.
- the pellets are then with the help of the blasting medium through the compressed air hose 32 and Connection hose 58 transported to the air lance 26 and via the nozzle 28 blasted onto the pipe wall.
- This will have the cleaning and peeling effect of the blasting medium is supported in three ways: On the one hand contaminants or explosive residues adhering to the pipe wall mechanically removes the abrasive effect of the pellets.
- the low temperature of the dry ice embrittlement of the part to be removed Material so that it can be smashed and detached more easily.
- there is a strong one Temperature differences between the wall of the sewer pipe 12 and the wall adhering impurities so that the impurities by differential thermal shrinkage can be removed.
- This cleaning effect can be used to advantage not only when removing explosive residues, but also when removing other stuck contaminants.
- the use of dry snow or dry ice has the further advantage that the risk of ignition due to frictional heat is avoided by intensive cooling.
- the residue-free sublimation of the dry ice into gaseous CO 2 eliminates the need to dispose of the blasting agent; even when using air as the blasting medium, an inert or at least inert atmosphere is created, which further reduces the risk of explosion.
- an earth strap 68 made of a conductive material, such as made of copper attached over the (mostly damp) sole of the sewer pipe 12 grinds and thus ensures that all parts of the robot 10th and the sewer pipe 12 are at the same potential.
- the compressor and the generator 64 also become closed Grounding purposes placed on metal grids or otherwise grounded.
- the collecting device not shown in FIG. 2, for the detached ones Explosive remnants consist of conductive materials and are grounded.
- the rubber sleeve 48 can, for example, by embedded metal wires or Graphite particles are made conductive. If the detached residual explosives are suctioned off immediately, preferably a water ring pump used. It is to avoid static electricity also possible to prepare the wall of the sewer pipe 12 or during the Cleaning process with the help of the robot 10, for example by a Water mist is sprayed onto the pipe wall.
- the air lance 26 is provided with a side hole 70, to branch off part of the compressed air jet and onto the lens of the To direct TV camera 34 and clean them of impurities.
- the side hole 70 is dimensioned that compressed air and blasting media are separated.
- the blasting agent (approximately the dry ice pellets) and also fed via a separate hose are fed into the air lance 26 only shortly before the nozzle 28.
- the procedure described here for removing explosives residues in sewer pipes can also be used in the context of the elimination of military Use contaminated sites to remove the explosives from ammunition cases.
- the air lance is not on a self-propelled frame, but rather mounted in a stationary device. Can also on the turret in this case, be dispensed with if the ammunition case on a rotatable Table is opened.
- the proposed robot is also suitable for cleaning pipes in industrial plants, drain pipes in landfills and the like.
