Definitions

  • the invention relates to a towing head for suction excavators for suction of soil, mud or the like from one Waters that have a suction pipe with the suction excavator is connected and which is a vortex visor and a nozzle bar has, the emerging from the nozzles downward water jets loosening the Effect soil or the like.
  • Such trailing heads are used in load suction dredgers to promote water-soil mixtures Waters and are connected via suction pipes with one on the Load suction excavator pump, for example a centrifugal pump.
  • the towing head of a cargo suction dredger of the most essential components because it is the first Link in the conveyor system has a decisive influence on solids production.
  • the design of the trailing heads is primarily dependent on the type of soil to be extracted. For Increase in the mixture concentration of the flow at Dredging of consolidated soil has become the feeder proven by pressurized water.
  • the pressurized water is here over arranged in front of the suction mouth of the trailing head Nozzles fed in a row - conveniently in a nozzle bar - are arranged side by side. By the downward emerging from the nozzles Water jets loosen the soil.
  • the Pressurized water flow is here via pressurized water nozzles the bottom of the body of water and the flow of driving water through at least a motive water nozzle on the suction pipe of the trailing head directed.
  • the pressurized water nozzles are on the front Edge of the suction area of the trailing head and the Driving water nozzles arranged on the rear edge, being the nozzles are firmly connected to the trailing head.
  • Another known trailing head for suction excavators are injection nozzles in such a distance from the inlet opening of the trailing head arranged that released by the loosening work Gases essentially outside of suction work of the towing head remain (EP 0 075 358 B1).
  • the injection nozzles through a series of openings in a tube extending transversely to the suction direction educated. Vary the position of the nozzle openings to be able to, the pipe located in a holder be rotated by means of a hydraulic cylinder.
  • a drag head is also known, in which behind the A visor for supplying pressurized water is provided (EP 0 892 116 A1). This visor is supposed to too much turbulence in the loosened soil prevent.
  • the invention has for its object a drag head for suction dredgers so that everyone can Excavation depth without optimal effort an optimal setting of the nozzles for the supply of pressurized water is guaranteed.
  • the trailing head Due to the inventive design of the trailing head is the position of the one in the nozzle bar Nozzles only depending on the position of the vortex visor and therefore always optimal because the vortex visor due to its function regardless of the excavator depth occupies the same position on the floor.
  • the inventive design of the trailing head another significant advantage that a universal joint in No longer a side suction pipe and therefore also an articulated crane required are. This results in a significant one Reduction of the construction weight.
  • the nozzle bar arranged on the vertebrae such that the center lines from the nozzles attached to the nozzle bar emerging water jets with the vertical one Form an angle that - in relation to the towing direction - is not greater than 10 °.
  • the means for attaching the nozzle bar to the swivel visor designed to be detachable. This facilitates an exchange of the Nozzles and allows the installation of different Nozzles.
  • the feeding takes place the pressurized water to the nozzle bar via pipes, at least a section of which is a flexible hose connection is trained.
  • the water supply can thereby follow every movement of the nozzle bar.
  • the supply of the pressurized water to the nozzle bar is thereby facilitated that between the lines for the Supply of the pressurized water and the nozzle bar Water supply box is provided.
  • the trailing head according to the invention can thereby be improved that the means for attaching the Nozzle strip on which the vortex visor is designed in such a way that the angular position of the nozzle bar to the vortex sight is changeable.
  • This is a very precise setting the angular position possible.
  • a different one Angular position can be useful if at different softness of the water floor between two dredging trips or in different places of the Dredging or at different speeds of the excavator the trailing head different amounts sucks off soil per unit of time.
  • Varying the depth of cut and thus the Sink depth of the vortex sight can be adjusted Appropriate angular position of the nozzle bar to the vortex sight his.
  • the angular position of the nozzle bar to Vortex visor can both before and before excavators be adjusted during excavation.
  • the length-adjustable element is expediently used as Hydraulic cylinder trained.
  • this embodiment of the invention is a very exact adjustment of the angular position of the nozzle bar for Vortex visor.
  • the trailing head according to the invention for suction excavators draws is characterized by a particularly simple design and requires very few components.
  • the drag head 1 shown in Fig. 1 is a Suction pipe 2 with the - not shown - suction excavator connected.
  • the towing head 1 is with a vortex visor 3 provided that on the trailing head 1 about an axis A is pivotally mounted and the free end under Dead weight rests on the floor 6.
  • a nozzle bar 4 is attached on the vortex visor 3.
  • This nozzle bar 4 is attached to the vortex visor 3 in such a way that the center lines M of the water jets 5, which from the emerge from the nozzle strip 4 provided with the perpendicular S form an angle W.
  • the feeder of the pressurized water to the nozzle bar 4 takes place via Lines, at least one section of which flexible hose connection 7 is formed.
  • a water supply box 8 is provided, which is rigidly connected to the vortex visor 3.
  • the water supply box 8 is not rigid with the vortex visor 3 connected, but about the same axis A swiveling, like the vortex visor 3.
  • the water supply box 8 is thus opposite the vortex visor 3 pivotally arranged.
  • a hydraulic cylinder 9 is provided as another fastener between the vortex visor 3 and the water supply box 8. Since the Nozzle bar 4 attached to the water supply box 8 is the position by means of the hydraulic cylinder 9 of the angle W that the center lines M of the water jets Form 5 with the vertical S to the vortex visor 3 can be set or changed.
  • the attached to your vortex visor 3 Water supply box 8 two lateral water supply channels 11 to which in the illustrated Embodiment the flexible hose connections 7 are connected.
  • the two lateral water supply channels 11 are through a distribution pipe 12th connected, on the underside of which the nozzle strip 4 is appropriate.
  • the nozzle bar 4 can also consist of several parts be trained.
