Definitions

  • the invention relates to a vehicle for loosening and sucking up contaminants from sewers and sludge pits.
  • Such vehicles are commonly referred to as sewer cleaning vehicles.
  • a high-pressure hose and a suction hose are inserted into the sewer. Water is pumped into the sewer through the high pressure hose; this water is also used to propel the high pressure hose into the sewer.
  • the high-pressure hose By pulling the high-pressure hose backwards through the channel, the water exiting backwards through a nozzle of the high-pressure hose can clean the channel wall of adhering dirt.
  • the accumulated sludge components are then sucked through the suction hose into a storage container of the sewer cleaning vehicle.
  • a sewer cleaning vehicle in which the telescopic boom with suction hose and high pressure hose should be pivotable by at least 360 degrees, so that an annular working area results around the sewer cleaning vehicle.
  • the high-pressure hose is wrapped around a pivot bearing located on the vehicle, overlapping at least to a certain extent. This leads to increased friction, which restricts the propulsion and mobility of the high-pressure hose.
  • the DE 20 2016 002 943 U1 discloses a sewer cleaning vehicle with a pivoting telescopic boom in which the high-pressure hose and the suction hose are guided together.
  • the high pressure hose is mounted on a hose reel so that it can be wound up and unwound and is guided out of the vehicle and into the telescopic boom approximately parallel to the longitudinal axis of the vehicle.
  • the telescopic boom is rotatably mounted on a horizontally arranged pivot bearing. This rotary bearing has a storage unit for the suction hose in the form of a hose reel.
  • the rotary bearing also has rollers for the high-pressure hose, which are arranged in a circle around the axis of the rotary bearing and are present below the hose reel for the suction hose.
  • the high-pressure hose rests at least in sections on the roller bodies of the pivot bearing, while the high-pressure hose is guided directly from the hose reel into the telescopic boom in a second position of the telescopic boom without touching the roller bodies of the pivot bearing. In this way, a work area of around 300 degrees can be covered by the telescopic boom.
  • sewer cleaning vehicles which have a hose reel as a storage device for the suction hose
  • sewer cleaning vehicles in which the suction hose is arranged in a cassette compartment.
  • a vehicle is, for example, from EP 0 698 696 B1 famous.
  • the vehicle disclosed there has a suction hose which can be positioned over the opening of a channel by means of a pivoting telescopic boom.
  • the suction hose can be transported out or in from a horizontally arranged cassette compartment which is located above the vehicle and serves as a storage unit.
  • the telescopic boom can be positioned either in front of or behind the vehicle, with the telescopic boom protruding beyond the clear cross-section of the vehicle in any position.
  • a high-pressure hose that is routed together with the suction hose in the telescopic boom.
  • the high-pressure hose can be withdrawn from a hose reel at will.
  • such channels or mud pits can be reached with the telescopic boom that are in an angular range of about 90 degrees to the vehicle's longitudinal axis, either immediately behind or immediately in front of the vehicle.
  • the invention is based on the object of specifying an improved sewer cleaning vehicle that enables a cassette compartment as a storage device for the suction hose and yet covers the largest possible working area.
  • sewer cleaning vehicle according to the invention is given by the features of main claim 1. Useful further developments of the invention are the subject of further claims which follow this claim.
  • the vehicle according to the invention for loosening and sucking off contaminants from sewers and sludge pits has a pivoting telescopic boom which can be positioned over the opening of the sewer or the sludge pit.
  • a high-pressure hose is mounted on a hose reel so that it can be wound up and unwound.
  • the high-pressure hose can be guided out of the vehicle and into the telescopic boom approximately parallel to the longitudinal axis of the vehicle.
  • a suction hose is stored in a storage device on the vehicle so that it can be transported in and out.
  • the high pressure hose and the suction hose are routed together in the telescopic boom.
  • the high-pressure hose and the suction hose are at least partially guided on roller bodies, at least some of which can be motor-driven.
  • the suction hose is guided into the telescopic boom via a pair of rollers fixed to the vehicle.
  • a first guide rail is pivotably mounted on the pair of rollers fixed to the vehicle, and a second guide rail is pivotably mounted on the telescopic boom.
  • the two guide rails are connected to one another via a sliding block.
  • the slidably mounted sliding block is present at each end of the guide rails.
  • the two guide rails therefore only overlap minimally, so that the pair of rollers fixed to the vehicle is as far away as possible from the pivotable mounting of the telescopic boom.
  • the telescopic boom In its parked position, the telescopic boom is parallel to the vehicle's longitudinal axis and directed backwards.
  • the two guide rails overlap more and more as the pivot angle increases, so that the distance between the pair of rollers fixed to the vehicle and the pivotable mounting of the telescopic boom is increasingly shortened.
  • a work area of around 270 degrees can be covered by the telescopic boom.
  • the work area can cover the area immediately behind as well as the area to the side of the vehicle.
  • the sewer cleaning vehicle would only have to be moved a little forward. A cumbersome maneuvering of the sewer cleaning vehicle is not necessary.
  • a first pair of rollers for the suction hose can preferably be fixedly attached to the first guide rail.
  • a second pair of rollers for the suction hose can be fixedly attached to the second guide rail.
  • the first or the second pair of rollers can in particular be fastened to the end region of the respective guide rail remote from the sliding block in order to allow the suction hose maximum mobility and at the same time to ensure safe guidance within the permissible bending radius of the suction hose.
  • At least one vertically aligned roller pair for the hydraulic hoses can be arranged on the first and / or the second roller pair for the suction hose.
  • Several hydraulic hoses can be arranged one above the other and each have a certain mutual distance from one another. This can be made possible by an appropriate hose guide.
  • the hydraulic hoses can then be guided by means of the vertical pairs of rollers, with several hydraulic hoses being able to be guided one above the other through the same pair of rollers.
  • a vertical pair of rollers for the hydraulic hoses can preferably be arranged on both sides of the first and / or the second roller pair for the suction hose. This means that the hydraulic hoses can be laid on both sides of the suction hose.
  • the first and / or the second pair of rollers for the suction hose can be rotatably attached to an upper rail.
  • This upper rail can have an extension on both sides, on each of which a vertically aligned pair of rollers for the hydraulic hoses is rotatably mounted.
  • the first and / or the second roller pair can preferably be rotatably mounted between an upper and a lower rail in order to optimize the stability of the roller pairs for the suction hose.
  • At least one horizontally aligned guide roller for the hydraulic hoses can be arranged.
  • the horizontally aligned guide roller prevents the hydraulic hoses from moving upwards or downwards, depending on their position. This could lead to the hydraulic hoses getting caught in the telescopic boom and thus to malfunctions in the sewer cleaning vehicle.
  • the at least one horizontally aligned guide roller for the hydraulic hoses can in particular be directed towards the telescopic boom and thus preferably be arranged on the second pair of rollers for the suction hose.
  • the hose reel for the high-pressure hose can preferably be arranged in the area directly behind the driver's cab of the vehicle.
  • the storage device for the suction hose can basically be designed as a hose reel or as a cassette compartment. If the storage device is designed as a cassette compartment, there can preferably be a substantially planar support for the suction hose, on which the suction hose can be placed with variable length in the area between the telescopic boom and its end-side attachment to the tank of the vehicle.
  • the high-pressure hose and the suction hose can be guided one above the other or next to one another in the profile of the telescopic boom.
  • the vehicle is protected from dirt adhering to and carried along from the sewer.
  • the high-pressure hose and the suction hose are arranged one above the other, the profile of the telescopic boom can be kept as low as possible so that a compact design can be achieved.
  • the high-pressure hose and the suction hose can also be partially or completely guided outside the profile of the telescopic boom.
  • a sewer cleaning vehicle 10 has a chassis 12 adapted to its maximum load (see FIG Fig. 3 ).
  • a hose reel 16 is provided behind the driver's cab 14 of the vehicle 10, on which a high-pressure hose 18 is wound.
  • a tank 20 is again located behind the hose reel 16 in a manner known per se.
  • the tank 20 serves as a storage device in order to be able to store sludge that has been sucked off.
  • further tanks or other containers can also be provided, for example to keep a cleaning liquid in stock. If only a single tank 20 is provided, this tank 20 can have an interior subdivision so that the extracted Sludge can be stored separately from the fresh water as cleaning liquid.
  • a cassette compartment 22 as a storage device for a suction hose 24 is mounted above the tank 20 and the hose reel 16 as well as the driver's cab 14.
  • the suction hose 24 is supported on the cassette compartment 22.
  • the suction hose 24 has a connection to the tank 20 at its end 26 on the vehicle side.
  • the end of the high-pressure hose 18 wound onto the hose reel 16 also has a line connection to the tank 20, so that pumps (not shown) spray water through the high-pressure hose 18 and sludge can be sucked into the tank 20 through the suction hose 24.
  • a telescopic boom 30 is also arranged above the tank 20.
  • the telescopic boom 30 is mounted pivotably about an axis 32.
  • the high-pressure hose 18 can be unwound from the hose reel 16 and guided into the telescopic boom 30.
  • the high-pressure hose 18 is unwound approximately in the longitudinal direction 34 of the vehicle 10 from the hose reel 16 and wound onto it.
  • the high-pressure hose 18 is guided by several roller bodies 36.
  • the roller bodies 36 have a surface that is adapted to the rounded surface of the high-pressure hose 18.
  • the suction hose 24 and the high-pressure hose 18 are guided one above the other in the telescopic boom 30, with the high-pressure hose 18 being guided within the profile of the telescopic boom 30 and the suction hose 24 above the profile of the telescopic boom 30 in the telescopic area 38 of the telescopic boom Suction hose 24 on roller bodies 40, which have a surface adapted to the rounded surface of suction hose 24.
  • Comparable roller bodies 40 are also present in the arcuate area 42 of the telescopic boom 30, in which the suction hose 24 is guided within the profile.
  • Some of the Roller bodies 40 can be driven by a motor, so that the suction hose 24 can be moved back and forth in the telescopic boom 30.
  • the high-pressure hose 18 also rests on further roller bodies 36 in the arcuate region 42 of the telescopic boom 30. These roller bodies 36 can be driven by a motor, so that the high-pressure hose 18 can be moved back and forth in the telescopic boom 30.
  • the roller bodies 36 for the high-pressure hose 18 can be driven independently of the roller bodies 40 for the suction hose 24, so that the high-pressure hose 18 and the suction hose 24 can be wound and unwound independently of one another.
  • the telescopic boom 30 can be extended by a maximum distance 44.
  • the distance between the front end area of the suction hose 24 and the high pressure hose 18 from the axis of rotation 32 can be increased so that a larger area around the vehicle 10 can be reached with the front end area of the suction hose 24 and the high pressure hose 18.
  • a work area 46 around the rear of the vehicle 10 can be reached in this way.
  • the work area 46 covers an angle of approximately 270 degrees. Only a narrow angular range of approximately 90 degrees in the area of the driver's cab 14 cannot be reached by the telescopic boom 30 in this case.
  • telescopic boom 30 is shown in its rear transport or parking position 50.
  • the telescopic boom 30 is aligned in this case parallel to the longitudinal direction 34 of the vehicle 10; the front end area of the telescopic boom 30 is oriented counter to the direction of travel in the direction of the rear of the vehicle. From this transport or parking position 50, the telescopic boom 30 can be pivoted clockwise and counterclockwise by 135 degrees each (see FIG Fig. 2 ).
  • the suction hose 24 is guided into the telescopic boom 30 by means of a pair of rollers 52 fixed to the vehicle.
  • the pair of rollers 52 fixed to the vehicle lies in the transport position 50 of the telescopic boom 30 in the longitudinal axis 54 of the telescopic boom 30 (see FIG Fig. 1 and 6th ) on the edge area of the cassette compartment 22.
  • a first guide rail 56 is mounted on the pair of rollers 52 fixed to the vehicle so that it can pivot about an axis of rotation 58 (see FIG Fig. 7 ).
  • a second guide rail 60 is also mounted pivotably about a second axis of rotation 62.
  • the two guide rails 56, 60 are connected via a slidably mounted sliding block 64 (see in particular Fig. 11 ) connected with each other. If the telescopic boom 30 is in its parking position 50, the two guide rails 56, 60 lie in the longitudinal axis 54 of the telescopic boom 30. The two guide rails 56, 60 overlap only minimally in the area of the sliding block 64 (see also Figures 9 and 10 ). If the telescopic boom 30 is pivoted from this parking position 50, the two guide rails 56, 60 gradually overlap more and more. At the same time, the distance between the axis of rotation 58 of the first guide rail 56 and the axis of rotation 62 of the second guide rail 60 is also reduced (see FIG Figures 7 and 8 ). As a result, the suction hose 24 is no longer guided over the axis of rotation 32 of the telescopic boom 30; rather, the suction hose 24 bends in front of the axis of rotation 32 of the telescopic boom 30.
  • a first pair of rollers 70 for guiding the suction hose 24 is fixed in place on the first guide rail 56.
  • a second pair of rollers 72 for guiding the suction hose 24 is fixed in place on the second guide rail 60.
  • the two pairs of rollers 70, 72 each have two rollers 74, which have a concave surface that is adapted to the rounded surface of the suction hose 24.
  • the rollers 74 each have a vertical axis of rotation 76.
  • the two pairs of rollers 70, 72 are arranged on the end region of the guide rails 56, 60 remote from the sliding block 64 and thus in the vicinity of the axes of rotation 58, 62 of the guide rails 56, 60. This also shortens the distance between the two pairs of rollers 70, 72 as soon as the telescopic boom 30 is pivoted out of its parking position.
  • the two rollers 74 of the roller pairs 70, 72 are each rotatably mounted on a lower rail 78.
  • the lower rail 78 is attached to the first and second guide rails 56, 60, respectively (see in particular Fig. 12 ).
  • the two rollers 74 of the roller pairs 70, 72 are each rotatably mounted on an upper rail 80.
  • the two upper rails 80 each have an extension 82, 84 on both sides, which is designed approximately in the shape of a staircase.
  • a vertically aligned pair of rollers 86 is rotatably mounted on each of the extensions 82, 84.
  • Each vertically aligned pair of rollers 86 has two rollers 88, which in the present example are cylindrical and are rotatably mounted between the extension 82, 84 and a lower web 90.
  • a plurality of hydraulic hoses 92 can be guided between the two rollers 88 of a vertically aligned roller pair 86 (see in particular Fig. 6 , 7 and 8 ).
  • the guide rails 56, 60 and thus also the vertical pairs of rollers 86 for the hydraulic hoses are at the level of the suction hose 24 (see in particular Fig. 4 ).
  • the hydraulic hoses 92 generally have a fixed length which is not changed during the pivoting of the telescopic boom 30.
  • the horizontal guide roller 94 is cylindrical and, viewed in the longitudinal direction 54 of the telescopic boom 30, is arranged in front of the vertical roller pair 86.
  • the horizontal guide roller 94 thus points in the direction of the arcuate region 42 of the telescopic boom 30.
