Definitions

  • the invention generally relates to a device for processing duct walls by means of high-pressure liquid jet. It relates in particular to a device which operates in closed channels, even in non-accessible channels, thereby removing obstacles or adhesions to the surfaces of the channel wall with the high-pressure liquid jet.
  • the invention also relates to a high pressure liquid jet method using such a device.
  • the devices can be designed for various processing, so that the applicability of the high-pressure liquid jet extends to very different areas.
  • the devices In order to maintain the ductility of a channel, obstacles or buildup on the channel walls, which can lead to blockages, are regularly eliminated.
  • line cuts are made or cut through appropriate beam management even complex shapes. It is known to add solid particles to the liquid jet in order to enhance the abrasive action.
  • the abrasive jet is directed in the channel direction or at a deviating from them by degrees angle for section or even progressing processing, so that an obstacle or an attachment is removed.
  • the device is moved forward through the channel.
  • the device must then regularly moved out of the channel and the removed materials are eliminated.
  • One application is the processing of the inner surfaces of closed channels with various cross-sections.
  • a channel When closed, a channel is to be understood, whose wall is fully formed, wherein the shape of the cross section may be arbitrary.
  • Such channels often also have channel branches which lead into side channels. The latter usually have a smaller cross section than the main channel and are often not accessible for inspection and cleaning purposes. If channels and channel branches are described below, this is done only to distinguish the position and size. In any case, these are channels that work on their walls is.
  • the obstacles or adhesions to be removed from the channel wall, from main and side channels, can have very different extents. They may be localized or may be partially to nearly complete closures of the channel. In any case, a replacement is up to the sewer wall the goal. This often requires a very high radiation power and sometimes leads to large amounts accumulated Abraumguts. Both complicates the treatment of the channel wall itself as well as the forward movement of the device through the channel, especially in small inaccessible channels.
  • a device for cutting and removing obstacles and deposits in non-accessible and accessible pipes and channels reveal, for example, the DE 20 2010 016 857 U1 and DE 10 2010 006 608 A1 wherein the cutting and ablation takes place by means of a water abrasive suspension jet.
  • a mobile, motorized tool carrier is moved in the channel, while the processing of the channel wall takes place, and thereby positioned by means of a supporting wheels having support device in the channel.
  • This device is particularly designed for a targeted removal of uniform and, relative to the channel diameter, thin coatings such as protective layers, wherein it depends on a uniform effect of the jet medium on the entire circumference of the channel and the channel length. Uneven and extensive obstacles and closures are often not eliminated with the nozzle assembly and the tool carrier. Due to the high impact force required for larger obstacles or buildup, the device may be forced out of position so that the force does not efficiently act on the material being abraded.
  • a propulsion of the device after a processing step be it during an interruption of processing or after complete elimination of a bottleneck in the channel, done without always fetch the device from the channel to remove the spoil can.
  • the passage between the processing space in front of the device and the space behind the device, which is left open by the device and the fixing pad, makes it possible to move the device as well as to flush out material to be excavated by the blasting medium or, optionally, to add additional flushes during operation.
  • the processing can be significantly accelerated, without having to compromise on the result.
  • bottom is gravity, since the more or less inclined, d. H. essentially horizontally extending channels, the removal of blasting medium and overburden takes place predominantly in the lower region of the cross section. With vertically ascending channels no underside is to be defined in this sense. Nevertheless, according to the invention, at least one region of the cross section for removal, analogously to horizontal channels, should also be kept free here. For the sake of simplicity, this area should also be referred to as "underside”, whereby it is irrelevant due to the uniform gravity which area serves as the "underside”, in particular since according to the invention a distance to the channel wall can also exist in other areas of the cross section or completely.
  • the device or at least the component of the device which has the nozzle body is kept constant during the entire operation in the position in the channel cross-section, so that even with a locomotion the distance between the bottom and the channel wall is maintained.
  • the trolley comprises suitable movement and support elements that allow the movement of the trolley and support it in at least two directions to the channel wall. Supporting in more than two directions allows clamping in the channel cross-section.
  • the pressing force for supporting and the connection of the movement and support elements on the channel wall can vary. In the simplest case, the e.g. via slide bearings, skids or support wheels done.
  • the device described can also be moved backwards through the channel and the processing on the front side, e.g. in sections, make.
  • the alternating activation of the fixing pad during processing and deactivation during the movement also supports this mode of operation.
  • the fixing pad can basically be activated pneumatically or hydraulically, as far as the fixation under the load during operation of the device can be guaranteed.
  • the existing media supply can be used effectively.
  • fixation pad is pneumatically activated, this has the additional advantage that activation and deactivation, i.

  • a beam which is greatly limited in diameter by means of the nozzle opening is regarded as a "collimated" beam, with which a locally limited high force can be exerted on the material to be ablated.
  • a larger number of nozzles is used and / or the surface is swept over by movement of the nozzle or the jet.
  • a sweeping is achieved, for example, by a rotary nozzle in which either the nozzle body rotates itself or rotates in the nozzle body in the region of the jet exit, for example, a finger-like insert in the cavity before the exit, so that the exiting jet gyrates and as a result a conical jet forms.

  • the carriage and the nozzle body are two components which can be moved and positioned separately in the channel. This makes it possible to introduce only the nozzle body in less accessible sections of the channel, especially in those in which the carriage can not retract due to a smaller cross-section or too sharp bend in the channel course. These can be bottlenecks or channel branches, for example.
  • the gripping of the nozzle body implies that it is either grasped on and detached from the vehicle or at a position away from the vehicle, provided that the nozzle body has already been separated from the vehicle before this step of insertion into the channel section.
  • the holding and moving of the nozzle body by means of the gripping and guiding element includes that the nozzle body can be inserted into the respective channel section and positioned there. It may also include propulsion of the nozzle body for machining the channel wall.

  • this is possible by a central, ie central open passage is formed or such Passages between the channel wall and Fixierpolster exist.
  • the fixing pad can sit on the outer circumferential surface of a hollow cylinder.
  • the fixing pad may be made of a plurality of pad segments, which are at least in the region of the channel wall spaced from each other.
