This also makes it possible to adapt to different diameters of the tube bundle 30 or the flange 32.
  • the support rollers 49 can be driven in rotation by an (electric) drive motor (not shown in detail) for each support roller 49. By driving the support rollers 49 in the same direction, the entire tube bundle 30 is rotated, so that all tubes are successively brought into a working position for cleaning can.
  • the bundle bracket 48 is arranged at a distance from the flange bracket 47 and provided with a plurality of support rollers 51. These extend freely rotatably in the longitudinal direction of the tube bundle 30. As can be seen, for example, from FIG. 5, four support rollers 51 with different heights - two each at the same height - are arranged. Smaller tube bundles 30 lie on the inner support rollers 51, while larger tube bundles 30 are carried exclusively by the outer support rollers 51.

  • the lance frame 46 is detachably attached to the frame portal 36 or to the lifting frame 43. It can be removed for external cleaning. The same applies to the transport phase of the facility.
  • the lance frame 46 is designed as an elongated hollow box. Within the same, the lances 44 are preferably arranged side by side in a horizontal plane. At one end, the lances 44 telescopically emerge from the lance frame 46.
  • each lance 44 is assigned a separate feed chain 57, expediently with a common drive (not shown) for all feed chains 57.
  • Each feed chain 57 is with the free back End of the lance 44 connected by a lance carrier 58.
  • This is block-shaped and at the same time serves to connect a supply line in the form of a high-pressure hose 59 to the end of the lance 44.

  • the transverse spindles 62 which are spaced apart in the longitudinal direction, can be rotated together in one direction or the other by a common drive (lateral drive chains - not shown). It is expedient the lance 44 lying in the middle is immovable, while the lateral lances 44 are adjustable at a greater or smaller distance from it (see also FIG. 14).
  • the cross spindles 62 or their spindle nuts 63 are connected to a separate lance guide. In the exemplary embodiments shown, this is designed as a lance support tube 64 with a square, in particular square, cross section. Such a enveloping lance support tube 64 is assigned to each lance 44. In the exemplary embodiment according to FIG. 6, the spindle nuts 63 are attached to the underside of the lance support tubes 64.

This is open in the area in question opposite the hose trough 65, so that the high-pressure hose 59 can be moved between the positions shown, forming a wandering deflection 66.
  • the transverse displacement of the lances 44 is also carried out here by corresponding movement of the lance support tubes 64. These are suspended from transverse spindles 62 by spindle nuts 63 attached to the top of each lance support tube 64 and can be displaced transversely by turning them.
  • the advance of the lances 44 is also designed differently, namely by a common drive for all lances 44.
  • their lance carriers 58 are combined by a common, transversely directed connecting rod 67 and can thus be moved together, for example by laterally arranged chain drives ( Not shown).
