Definitions

  • the invention relates to a sludge suction vehicle with a hose rack above the sludge container, a telescopic boom for a suction hose, the telescopic boom being pivotable about a plane parallel to the storage plane of the hose rack and additionally vertical, and with a drive unit having drive rollers for retracting the hose onto or Extending the hose from the hose rest, the hose shifting on the hose rest as it moves in or out.
  • Such a mud suction vehicle is a waste disposal vehicle, the waste consisting of muddy deposits which are present in underground sewers or the like other channels or containers.
  • the waste container into which the suction hose opens can be evacuated so that the sludge is sucked into the container through the suction hose.
  • Such a mud suction vehicle is known from German utility model DE-U-8807777.
  • the sludge container In the front area of the vehicle, the sludge container has a dome, on which the hose holder, which extends above the sludge container, is supported off-center and is pivotably mounted about a vertical axis.
  • a telescopic boom guiding the suction hose is also pivoted in height on the hose rack.
  • the telescopic boom is tubular, with the suction hose inside the two Pipes is guided.
  • the invention has for its object to provide a mud suction vehicle of the type mentioned, which does not have the disadvantages known from the prior art and which can be used optimally even in restricted local conditions.
  • This invention is given by the features of the main claim. It is accordingly characterized in the mud suction vehicle of the type mentioned above in that the hose holder is firmly attached to the mud container, that a turntable is present outside the vehicle area covered by the hose holder above the mud container, which is pivotable about an axis perpendicular to the storage plane and on which is pivotally mounted about an axis parallel to the storage plane of the telescopic boom. Furthermore, there are first drive rollers in the area between the slewing ring and the hose holder and second drive rollers in the area of the telescopic boom for extending and retracting the hose.
  • the hose area that is kinked when the telescopic boom is pivoted horizontally and / or vertically is "framed" by drive rollers on both sides, which only enables this kinked hose guide.
  • the two roller drives for the hose also have the effect that the hose can be guided in its kinked area in the correct direction along the arch it occupies when retracting and extending and does not wind out of its respective arch or otherwise buckle.
  • roller-shaped roller bodies are provided on the hose rack according to a very important feature of the invention, on which the hose in the area of Storage rests.
  • the axes of these reel bodies lie, in particular, in one plane and are aligned parallel to one another in such a way that when the hose is extended and retracted, the same is on rolls along the rollers.
  • first piston-cylinder unit for pivoting the telescopic boom, the cylinders of which are attached to the slewing ring and the pistons of which are attached to the telescopic boom
  • second piston-cylinder unit for adjusting the length of the telescopic boom, the cylinders of which are attached to the non-extendable one Telescopic part and its piston is attached to the telescopic part movable in the hose direction.
  • a hose guide bend is attached to the free end of the movable telescopic part. Rollers for guiding the hose can be attached to this hose guide bend.
  • the slewing ring Due to the inventive construction, it is possible to design the slewing ring to be pivotable about 180 to 220 degrees about its vertical axis of rotation and still to bend the relatively thick suction hose in a relatively narrow space without any problems.
  • a mud suction vehicle 10 has a mud tank 14 behind its driver's cab 12, in which a vacuum can be generated by means of a compressor device 16.
  • the hose rest 18 In the area above the driver's cab 12 and the front upper area of the sludge container 14 there is a hose rest 18 which extends in this area over practically the full width of the sludge suction vehicle 10.
  • the hose rest 18 essentially consists of a circumferential frame 20 which is approximately grid-shaped by transverse braces 22 and longitudinal braces 24. In the direction perpendicular to the longitudinal axis 26 of the mud suction vehicle, i.e. in the transverse direction, 24 roller-shaped rollers 28 are rotatably mounted between the longitudinal infills.
  • a suction hose 30 is supported on these rollers 28 in the region of the hose holder 18. One end of this suction hose 30 opens into a connecting piece 32, which opens into the sludge tank 14 in the eccentric region - lower in FIG. 2 - outside the hose holder 18.
  • a slewing ring 34 In the rear area of the vehicle 10, in the eccentric side area thereof opposite the neck 32, there is a slewing ring 34 above the sludge tank 14.
  • a bearing 40 having two fork arms 36, 38 and a telescopic boom 44 projecting beyond the rear 42 of the vehicle 10 are connected to this turntable.
  • the fork arms 36, 38 each carry in the region of their free ends a roller 46, 48 which can be rotated about a vertical axis and are each designed such that the hose 30 is guided laterally on them, between the fork arms 36, 38 can be.
  • the fork arms 36, 38 are fixedly attached to the slewing ring 34. When pivoting the turntable 34 about its vertical pivot axis 50, the bearing 40 also pivots in the same way.
  • rollers 52, 54, 56 in their function corresponding to the roller-shaped rollers 28, on which the hose 30 can be supported.
  • rollers 60, 62 on the side of the hose, opposite one another, between which the hose 30 is guided.
  • the telescopic boom 44 is articulated on the bearing 40 and thus on the slewing ring 34. It can thus be pivoted in height about the axis 72 present there, which is indicated by the arrow 74. This pivot axis 72 is at the same time the axis of rotation of an upper roller 75.
  • the movement of the telescopic boom 44 upwards and downwards, ie in the direction 74, is effected by cylinder-piston units present on the side of the same.
  • the cylinder 78 is fastened to the bearing 40 in the region of the axis of rotation 72, while the piston 80 is fastened to the non-extendable telescopic part 82 of the telescopic boom 44.
  • the telescopic part 82 essentially consists of the cheeks 84 which laterally delimit the tube 30 and which are connected to one another by lower roller bodies 86.
  • the hose 30 rests on these reel bodies 86.
  • the cheeks 84 each have lateral guides 88, which are bush-shaped.
  • a guide rod 90 is slidably mounted in these guides 88 in the longitudinal direction of the telescopic boom.
  • a telescopic part 92 is attached to the front end of the guide rod 90. This telescopic part 92 is also mounted so that it can be moved back and forth in the direction 98 by means of a piston 94 which can be moved within a cylinder 96 in the direction of the arrow 98.
  • a guide bend 100 for the hose 30 is attached to the telescopic part 92 and is provided with support rollers 102 for the hose 30.
  • a pair of rollers 104, 106 is present, which abuts against the suction hose 30 from below and above. These rollers 104, 106 are driven by a hydraulic motor 108 so that the suction hose 30 can be extended and retracted.
  • a block of four drive rollers 110 are present in the area between the swivel ring 34 and the hose holder 18, which lie in pairs laterally on the hose 30 and, to achieve an optimal contact pressure, by a fine adjustment device (not shown in more detail) as close as possible to the Hose can be put on.
  • the drive rollers 110 and the drive rollers 104, 106 are thus driven simultaneously, so that the hose 30 is framed by drive devices in the longitudinal direction in the region of its horizontal and / or vertical bend.
  • the hose can therefore not bulge or buckle in the area between its drive rollers 104, 106 and drive rollers 110.
  • the lateral guidance in this horizontal and / or vertical bending region of the hose 30 is further supported by the rollers 46, 48 provided at the ends of the fork arms 36, 38. Within the horizontal area between these rollers 46, 48, the hose 30 can move laterally when the telescopic boom 44 is pivoted horizontally.
  • suction hose 30 If the suction hose 30 is to be pulled more or less slightly away from the respective suction area, the drive rollers 104, 106 and 110 do not have to be driven and the suction hose thus have to be retracted a little, but the telescopic boom 44 can be raised correspondingly far for this purpose.
  • the suction hose 30 thus does not move relative to its drive rollers, so that wear on the surface of the suction hose caused by the drive rollers can be avoided.
  • a suction hose which is stuck in its suction position in a sewer or the like can therefore only be moved in the sewer duct by the upward and downward movement of the telescopic boom. It has been shown that such a movement of a suction hose occurs very frequently during a suction process and that the wear of the suction hose caused thereby is correspondingly intense.
  • the motor power required to drive the rollers 104, 106, 110 can be designed to be relatively small since the tube moves over the rollers 28 when it is moved on the tube holder 18 and consequently the frictional forces that otherwise occur during the displacement between the tube and the tube holder surface are extremely small.
