Definitions

  • the invention relates to a suction excavator according to the preamble of claim 1.
  • Such a suction excavator is known in the form that the anchoring means on both sides consist of regular anchors.
  • the disadvantage here is that these anchors must be relocated after each working cycle of the excavator, in which the available stroke of the pile car or stepping pile has been used up, which, particularly in view of the high holding forces required here, forms a relatively time-consuming work stoppage, and that in some, e.g. due to sedimentary reasons, anchors cannot be supported at all.
  • the invention is therefore based on the object of designing the anchoring means on both sides in such a way that they can be introduced and moved quickly and reliably even with a resilient reason.
  • the design of the anchoring means on both sides as vertical anchor piles similar to the anchoring pontoon of the excavator pontoon enables these anchor piles to be introduced quickly and selectively relatively deep into the ground.
  • the suction excavator shown has an excavator pontoon 2 with a suction pipe conductor 4 which is mounted therein in the longitudinal center thereof so as to be pivotable up and down.
  • the suction pipe conductor 4 carries in the usual way a suction pipe 10 which ends at its free end 6 and in this example ends inside a cutting head 8, in which a centrifugal pump 12 which is still arranged on the suction pipe conductor is provided. To convey its vertical pivoting movement, it is suspended from a lifting gear 14.
  • a pile wagon 20 which can be moved in the longitudinal direction of the excavator pontoon by means of a hydraulic cylinder 18 and in which an anchoring pile 22 for the excavator is mounted so that it can move up and down.
  • This anchoring pole is suspended from the piston rod 26 of a standing hydraulic cylinder 28 via a cable bottle 24.
  • a crosshead 30 is pivoted about the axis of the anchoring pile 22, on the ends of which project beyond the lateral side walls 32 of the excavator pontoon by means of universal joints 34 anchor trees 36 are supported.
  • the anchor booms 36 can be spread out by means of hydraulic cylinders 38 and, if necessary, can also be made up for again. They carry at their free ends, in this Example rigidly connected thereto, each an anchor pontoon 40, in which an anchor post 42 is mounted to move up and down. Similar to the anchoring post 22, this anchor post is suspended from the piston rod 46 of a hydraulic cylinder 48 by means of a cable bottle 44. It is understood that, although not shown here, the supply lines of the hydraulic cylinders 48 will run along the anchor trees 36 to the excavator pontoon 2.
  • a rope 50 engages which runs over a roller 52 at the free end 6 of the suction pipe conductor 4 to a winch 54 arranged on the excavator pontoon 2 .
  • alternating actuation of the two winches 54 can give the excavator pontoon 2 together with the suction pipe conductor 4 a reciprocating pivoting movement around the anchoring pile 22, in which the end 6 of the suction pipe conductor approaches one or the other of the two anchoring piles 42.
  • the pile wagon 20 is moved backwards by the hydraulic cylinder 18 relative to the excavator pontoon, ie the excavator pontoon is moved forward, the cutting head 8 thus always finds new food in the base 56.
  • the anchor booms 36 are folded up against the side walls 32 by means of the hydraulic cylinders 38 or the winches 54 when the anchor piles 42 are retracted (as is also the case in the figures) can be seen on the right-hand anchor tree), and finally the anchoring post 22 is also pulled in.
  • the excavator is now in a transportable condition.
