Definitions

  • the invention relates to a vehicle for loosening and vacuuming contaminants that are present in sewers and / or mud pits.
  • Such vehicles are referred to as sewer cleaning vehicles.
  • a high-pressure hose and a suction hose are inserted into the duct.
  • the high pressure hose pushes water into the sewer.
  • this water serves to propel the high-pressure hose into the sewer.
  • the high-pressure hose by pulling back the high-pressure hose, the water emerging from it is used to rinse the channel wall and to advance the accumulated sludge components into the area of the suction hose.
  • There is therefore a water supply in the sewer cleaning vehicle which is used to dissolve the sludge.
  • Sewer cleaning vehicles which are equipped with a suction pipe boom. This boom can be pivotally and tiltably attached to the tank of the vehicle. Such vehicles are preferably used to extract sludge from channels and sludge pits.
  • Flushing vehicles are known which are preferably used for cleaning channels and mud pits. Under high pressure, water is pressed into the sewer to be cleaned through a high-pressure hose that is rolled up on a reel and carried along on the vehicle.
  • sewer cleaning vehicles of the type mentioned at the outset are known, which are equipped with both a high-pressure hose and a suction hose.
  • Your telescopic boom which is designed to be pivotable and tiltable, serves to position the suction hose above the opening of the channel or the mud pit.
  • a high-pressure hose can be unwound from a hose reel attached to the vehicle and brought into the area of the sewer opening. Both hoses, the high pressure hose and the suction hose, can be handled and operated individually.
  • the disadvantage here is the separate insertion of suction hose and high-pressure hose, which means cumbersome handling.
  • the invention is based on the object of specifying an improved sewer cleaning vehicle compared to the prior art.
  • the invention is given by the features of the main claim.
  • the invention is characterized by the combination of features specified in claim 1.
  • the invention is based on the finding that by holding the high-pressure hose and suction hose together within a telescopic boom, both simple and exact positioning of these two hoses over the opening of a channel or a mud pit is possible, as well as good and easy handling of the two Hoses are made possible in terms of their unwinding and rewinding and in terms of the actual cleaning operation and thus driving the pumps and other units on the vehicle.
  • the telescopic boom must be positioned exactly above the opening of the channel, the telescopic boom must be designed to be movable in all four directions above a channel opening. This is made possible by the telescopic extension of the telescopic boom and also by its lateral pivotability. However, the pivoting of the telescopic boom is only possible in that motor drives for the high-pressure hose and for the suction hose are provided in front of and behind its pivot axis.
  • the front end of the telescopic boom can be provided constructively both on the front and on the rear of the vehicle.
  • the arrangement of the boom in front of the vehicle has the advantage that the vehicle operator can operate the vehicle without having to leave the driver's cab. In contrast, when the telescopic boom is positioned at the rear of the vehicle, the noise pollution from the engine of the vehicle is less.
  • This arrangement of the telescopic boom in the rear of the vehicle also has the advantage that the inevitable contamination of the vehicle during cleaning only affects its rear front and not also the front front. In both cases, however, it has proven to be sensible to arrange the hose reel directly behind the driver's cab of the vehicle. The area above the rear wheels of the vehicle can then be used in terms of weight of water and / or sludge containers carried along.
  • the diameter of the high-pressure hose is regularly smaller than the suction hose, it is advantageous to guide the suction hose above the high-pressure hose. This makes it possible to swivel both hoses around the same axis. Within the telescopic boom, the two hoses are held between the roller bodies.
  • a braking device for the hose reel is provided according to an advantageous embodiment of the invention, which can be controlled via a switching device so that when a predetermined minimum number of is reached wound windings, the braking device is activated and the further unwinding movement of the hose reel is interrupted.
  • This activation of the braking device is ended and the rotary movement of the hose reel is then made possible again when the unwinding drive for the at least one reel body of the high-pressure hose is switched off and / or the winding drive for the hose reel is switched on.
  • This switching device is characterized according to an embodiment by a lever member which is depressed when loaded by at least some of the turns of the lowermost layer of the high-pressure hose and can be swung up into a second position when relieved by these turns. When pivoting, it can come into switching contact with a proximity switch, for example, which then generates a control signal for the braking device of the hose reel. This ensures that the hose reel ceases to unwind before the high-pressure hose is completely unwound.
  • the suction hose can be guided particularly well in the region of the pivot axis of the telescopic boom, in that a pivot member is articulated on the one hand to the fixed part of the boom and with its other end to the pivotable region of the boom.
  • This connection is made by means of a cantilever which projects from the area of the boom that can be swung away stands out and is held longitudinally displaceably in a slot guide of the pivot member.
  • This swivel link has roller bodies, between which the suction hose is guided. This makes it possible to gently bridge the suction hose over the region of the pivot axis.
  • the hose is inserted into the swivel member via a cassette support on the top of the vehicle. In this edition, the suction hose can be more or less widely supported, preferably in a deflection.
  • a vehicle 10 is shown schematically, how it is used according to the invention for cleaning channels and mud pits and also for sucking up contaminants from such sewers and mud pits.
  • a hose reel 14, on which a high-pressure hose 16 is wound, is provided behind the driver's cab 12 of the vehicle 10.
  • tanks 18 and other containers are provided in a manner known per se, in which the water required for cleaning can be kept in stock and the extracted sludge sludge can be filled in.
  • a cassette compartment 20 is mounted above the tanks 18 and the hose reel 14 and the driver's cab 12, on which a suction hose 22 is supported.
  • the suction hose 22 has a connection to one of the tanks 18 on its vehicle-side end.
  • the end of the high-pressure hose 16 wound on the hose reel 14 also has a line connection to one of the tanks 18, so that water is sprayed out through the high-pressure hose 16 via pumps (not shown) Sludge can be sucked into corresponding tanks 18 through the suction hose 22.
  • a telescopic boom 24 is attached to the top of the vehicle and is positioned with its front end 26 behind the rear 28 in the vehicle according to FIG. 1, while in the vehicle 10.1 (Fig. 3) this front end 26 ends in front of the cab 12. Otherwise, the vehicle 10.1 shown in FIG. 3 largely corresponds to the vehicle 10 shown in FIG. 1.
  • the design changes resulting from the different arrangement of the telescopic boom are described in more detail below.
  • the front end 26 of the telescopic boom 24 is formed in the area 30 from the fixed part 32 of the telescopic boom 24 in the direction of the double arrow 32 to the contact surface 34 of the vehicle 10 or 10.1 in the horizontal direction to the front and rear.
  • the front end 26 is moved by means of hydraulic cylinders 36.
  • the front end 26 includes a frame arch 38 that ends in a frame header 40 below.
  • the frame arch 38 with the frame head part 40 are designed to be movable in the direction of the double arrow 32.
  • the suction hose 22 is held on the outside and the high-pressure hose 16 on the inside, each guided between deflection rollers.
  • the suction hose 22 is guided on the outside because of its larger diameter than the high-pressure hose 16.
  • Lower roller bodies 42 of the rollers abutting the suction hose 22 are shown in the region of the frame arch.
  • a roller body 44 is shown from the outside, ie from above.
  • Lower roller bodies 46 rest against the high-pressure hose 16 in the region of the frame arch 38 from below.
  • the high-pressure hose 16 is held in the region of the frame head part 40 once again from all directions by roller bodies.
  • the suction hose 22 does not require any special mounting in the area of the frame head part 40, since it also hangs sufficiently straight downwards for reasons of weight.
  • roller bodies 52 are in each case laterally on the suction hose 22. Both roller bodies 52 can also be driven by a motor. These two roller bodies 52 are pressed laterally by spring force onto the suction hose 22. This takes into account that the outer diameter of the suction hose 22 does not have a continuous, flat design.
  • a slipping or jumping of the roller body 52 along the suction hose 22 is excluded by the resilient contact of the roller body 52 on the suction hose 22.
  • the suction hose 22 can be moved back and forth along the telescopic boom 24 with the aid of the motor-driven roller bodies 50, 52.
  • the vertical pivot axis 56 of the telescopic boom 24 is formed in the area between the deflection rollers 50, 52. This fixed part 32 of the telescopic boom 24, which cannot be moved back and forth in the direction of the double arrow 32, will be described in more detail in connection with FIG. 5.
  • the high-pressure hose 16 is guided along in the fixed part 32 below the suction hose 22. It rests on lower roller bodies 60. In the present example case, in this area there are still lateral roller bodies 62 on the high-pressure hose 16, which can be driven by a motor and are thus available for pulling the high-pressure hose from the hose reel 14.
  • the high-pressure hose 16 is wound up by driving the hose reel 14 in the corresponding direction of rotation. During the winding process, the driven lateral reel bodies 62 are moved away from the high-pressure hose. This will a load on this reel body 62 avoided during the winding process. If the hose reel 14 were to be wound up correspondingly quickly and the speed of rotation correspondingly fast, the reel bodies 62 would have to rotate undesirably quickly when they were in contact with the high-pressure hose 16.
  • the motor-driven roller bodies 62 can also be positioned in the region of the frame arch 38.
  • the cassette compartment 20 known per se, which is equipped with cylindrical rollers 66 in a known manner, can be seen from above.
  • the suction hose 22 runs eccentrically to the longitudinal axis 68 into the telescopic boom 24.
  • the off-center motion control for a suction hose is known in vehicles of the type mentioned here.
  • the rear end 70 of the suction hose 22 leads into a corresponding tank 18 of the vehicle 10 in a known manner.
  • the telescopic boom 24 can be pivoted laterally by about 60 degrees in both directions (arrows 72, 73).
  • the pivot axis 56 is present perpendicular to the contact surface 34.
  • FIG. 5 shows the central area of the telescopic boom 24, which contains the swivel area.
  • the pivotable part 80 of the telescopic boom 24 is pivotally mounted in the horizontal direction about the pivot axis 56 (pivot point M).
  • On the part 80 is the motor-driven and press-fitting upper roller body 50 rotatably mounted.
  • a further lower roller body 82 is present, abutting the suction hose 22 from below.
  • 22 lateral roller bodies 84 are then provided for lateral guidance of the suction hose. All of these reel bodies are held by the pivotable part 80.
  • the motor-driven roller body 52 which presses against the side of the suction hose, is shown on the fixed part 32 of the telescopic boom 24 on the vehicle. Your pressing system is effected by a tension spring 86.
  • the fixed part 32 has a joint formation 88 at the front, to which the rear end 92 of a pivoting member 90 is pivotally attached.
  • the front end 96 of the pivoting member 90 has a slot 98.
  • a pin 100 engages in this slot 98 from below, which is supported on the fixed part 80 so as to project upwards.
  • the pin 100 moves along the slot 98 and thereby takes the front end of the pivot member 90 with it.
  • the pivot member 90 thus forms a bridge between the fixed part 32 and the pivotable part 80 of the telescopic boom 24. In this way, a gentle deflection of the suction hose 22 with a relatively large radius of curvature is technically simple and fully functional in the pivoting range of the boom.
  • the guide for the high-pressure hose 16 shown in FIGS. 6, 7 has nested pipes 102, 103 in the area between the pivot axis 56 of the telescopic boom 24 and the hose reel 14.
  • the high-pressure hose 16 runs inside through the pipes 102, 103.
  • the pipes 102, 103 prevent the high-pressure hose 16 from sagging in the area between the pivot axis 56 and the hose reel 14. This problem occurs particularly in the vehicle 10, where the hose reel is in the front area of the vehicle and the front end 56 of the telescopic boom 24 is in the rear area of the vehicle. In contrast, there is hardly any horizontal distance between the hose reel 14 and the pivot axis 56 in the vehicle 10.1.
  • a hose guide device 108 is provided above the hose reel 14.
  • the high-pressure hose 16 is positioned in its respective position over the hose reel 14.
  • a shaft 110 is provided laterally above the hose reel 14, along which a carriage 112 can be moved in the direction of the double arrow 114.
  • the axis 116 of the shaft 110 is aligned parallel to the rotary shaft 118 of the hose reel 14.
  • a guide roller 122 is held on the cantilever linkage 124 on the carriage 112 so as to be pivotable about a vertical axis 120.
  • rollers 126 attached laterally to the high pressure hose 16.
  • rollers 128 are arranged on the cantilever linkage 124 in such a way that the high-pressure hose 16 cannot jump upward out of the guide roller 122.
  • This hose guide device 108 works in the following way. Via an endlessly rotating drive 130, the carriage 112 is laterally displaced along the shaft 110 in accordance with the winding speed of the hose reel 14, so that the guide roller 122 is positioned exactly over the hose reel 14 in accordance with the respective winding to be made becomes. On the other hand, the guide roller 122 also pivots in the direction of the high-pressure hose 16 in the region between the lateral guide rollers 106, since the guide roller 122 can be pivoted about the axis 120 by the rollers 126 in the direction of the high-pressure hose 16.
  • the guide roller 122 is therefore aligned on the one hand in the direction of the guide rollers 106 and on the other hand also positioned above the position to be wound along the rotary shaft 118 of the hose reel 14.
  • the high-pressure hose 16 can be wound up and unwound in an exact alignment on the hose reel 14.
  • a spiral winding 134 is applied to the reel core 132.
  • This spiral winding 134 consists of a metal rod which is, for example, welded onto the core 132 in such a way that it fits into the spaces which are present on the hose reel 14 between the core 132 and adjacent turns 136 of the high-pressure hose 16 (FIG. 8, 9). In this way, the first layer of windings 136 can be wound exactly adjacent to one another on the hose reel 14.
  • the hose reel 14 is equipped with a switch-off device, not shown.
  • This switch-off device is forcibly activated and the unwinding drive of the hose reel 14 is stopped when in the present example case only the last two turns 136.1 and 136.2 are present wound up. In the present example, this is done in the following way.
  • a trough-like lever member 140 is pivotally mounted in the reel core 132.
  • Two coils 136.1, 136.2 are accommodated in its trough-like trough 142.
  • the lever member 140 is present in its pivoted position shown in solid line in FIG. 9. In this position, its right end 144 in the drawing has no contact with a proximity switch 146 which is electrically conductively connected to the shutdown device.
