Definitions

  • the invention relates to a vehicle for loosening and sucking off impurities from sewers and sludge pits.
  • Such vehicles are generally referred to as sewer cleaning vehicles.
  • a high-pressure hose and a suction hose are inserted into the canal. Water is pumped into the canal through the high-pressure hose; this water is also used to propel the high-pressure hose into the canal.
  • the high-pressure hose By pulling the high-pressure hose backwards through the channel, the water escaping backwards through a nozzle of the high-pressure hose can clean dirt adhering to the channel wall.
  • the accumulated sludge components are then sucked through the suction hose into a storage tank 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, resulting in an annular working area around the sewer cleaning vehicle.
  • the high-pressure hose is looped around a pivot bearing located on the vehicle, overlapping at least a little. 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 pivotable 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 approximately parallel to the longitudinal axis of the vehicle and into the telescopic boom.
  • the telescopic boom is rotatably mounted on a horizontally arranged rotary 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 In a first position of the telescopic boom, the high-pressure hose is at least partially in contact with the roller bodies of the rotary bearing, while in a second position of the telescopic boom, the high-pressure hose is guided directly from the hose reel into the telescopic boom without touching the roller bodies of the rotary bearing. In this way, a working range of around 320 degrees can be covered by the telescopic boom.
  • the invention is based on the object of specifying an improved sewer cleaning vehicle that enables the high-pressure hose to be guided as securely as possible.
  • the vehicle according to the invention for loosening and sucking up contaminants from sewers and sludge pits has a pivotable telescopic boom which can be positioned over the opening of the sewer or sludge pit.
  • a high-pressure hose can be wound and unwound on a hose reel.
  • the high-pressure hose can be approximately parallel to the longitudinal axis of the vehicle out of the vehicle and into the telescopic boom.
  • a suction hose is stored in a storage device on the vehicle so that it can be pulled in and out.
  • the high-pressure hose and the suction hose are routed together in the telescopic boom.
  • the telescopic boom is rotatably mounted on a horizontally arranged rotary bearing. This pivot bearing has roller bodies for the high-pressure hose.
  • roller bodies are arranged in a circle around the axis of the pivot bearing.
  • the pivot bearing has support rollers for the high-pressure hose, which are arranged around the axis of the pivot bearing.
  • the support rollers can be moved in such a way that in a first position they are approximately at the level of the roller bodies, so that the high-pressure hose is guided between the roller bodies and the support rollers.
  • the support rollers are present above or below the level of the roller bodies.
  • a working area of approximately 320 degrees can be covered by the telescopic boom.
  • the working area can cover both the area directly behind and the area directly in front of the vehicle. Only on the side of the vehicle is there an area that cannot be covered by the telescopic boom.
  • the sewer cleaning vehicle In order to be able to clean sewers and sludge pits in this area as well, the sewer cleaning vehicle only has to move back or forward a little. A cumbersome maneuvering of the sewer cleaning vehicle is not necessary.
  • the high-pressure hose can be prevented from slipping or jumping out of its roller track in the pivot bearing. This enables safe operation of the vehicle according to the invention even with extreme deflections of the telescopic boom.
  • the support rollers can be distributed over the entire pivot bearing and thus cover an angular range of 360 degrees.
  • the high-pressure hose is only in contact with the roller bodies of the pivot bearing in an area of less than 180 degrees, it may be sufficient to provide the support rollers only in this area of the pivot bearing and thus in an angular range of about 180 degrees. It has been found to be sufficient to provide the support rollers at a distance of about 30 to 45 degrees from one another, so that a total of five support rollers are sufficient.
  • the process of the support rollers from their first to their second position and vice versa can preferably be done via a link guide.
  • Link guides are easy to implement in terms of design and are generally not very prone to failure.
  • the link guide can have a turntable which is attached to the pivot bearing and can be rotated about the axis of the pivot bearing.
  • the link guide can have a stationary guide rail that is present below or above the turntable.
  • the support rollers can be mounted on the turntable so that they can be moved along the stationary guide rail and are vertically displaceable.
  • the stationary guide rail can be circular and have a first section and a second section. The distance between the stationary guide rail and the turntable can be smaller in the area of the first section than in the area of the second section.
  • the support rollers are therefore located in the area of the first section of the guide rail, they are aligned approximately at the same height as the roller bodies of the pivot bearing. If, on the other hand, the support rollers are in the area of the second track section, the support rollers have been moved downwards or upwards and therefore release the area of the rotary bearing to the outside.
  • the second section can therefore, in particular, in Be arranged in the pivot bearing area of the inlet of the high-pressure hose.
  • the stationary guide rail can preferably be arranged below the turntable.
  • the support rollers can each have at least one driving roller, through which the support rollers can be moved on the stationary guide rail.
  • support sleeves can be attached to the turntable, in which the support rollers are mounted so that they can be displaced longitudinally.
  • the high-pressure hose and the suction hose can be guided within the telescopic boom, at least in some areas, on roller bodies. At least some of these roller bodies can be designed to be motor-driven.
  • the pivot bearing of the telescopic boom can have a storage unit for the suction hose.
  • This storage unit can preferably be designed as a hose reel.
  • the roller bodies for the high-pressure hose can be present in particular below the storage unit of the suction hose.
  • the telescopic jib can have a jib arm that is preferably designed to be telescopic, and a guide element is integrally formed on the vehicle-side end of the jib arm.
  • This guide element can then be rotatably mounted on the pivot bearing.
  • the cantilever arm and the guide element can form an angle of approximately 100 to 110 degrees, so that the telescopic boom is designed in a quasi-kinked manner.
  • the boom arm of the telescopic boom can be designed to be telescopic once or multiple times.
  • This angled design makes it possible to further increase the working area of the sewer cleaning vehicle.
  • the telescopic boom in this case is not in the field of vision of the driver when the cantilever arm is aligned forward parallel to the longitudinal direction of the vehicle. In principle, it would therefore be possible to move the vehicle even if the telescopic boom is in front of the driver's cab. This would make the work of the driver of a vehicle according to the invention much easier and can also ensure that the travel times of the vehicle between two cleaning processes can be significantly reduced.
  • the high-pressure hose can be guided into the telescopic boom via at least one pair of rollers. If two pairs of rollers are to be present, they can form a funnel-shaped inlet for the high-pressure hose.
  • the high-pressure hose runs between the two rollers of the at least one pair of rollers.
  • the at least one pair of rollers is arranged in one plane with the roller bodies of the pivot bearing. If the telescopic boom is positioned to the side of the vehicle on the side of the hose reel for the high-pressure hose, the high-pressure hose can rest on the outer roller of the pair of rollers and be guided directly from the hose reel into the telescopic boom.
  • the high-pressure hose can lie against the inner roller of the pair of rollers and be transferred from this roller to the roller body of the rotary bearing. In this position of the telescopic boom, the high-pressure hose runs at least in sections around the rotary bearing.
  • the at least one pair of rollers of the telescopic boom can preferably be arranged in the transition area between the boom arm and the guide element and thus in the area of the bend in the telescopic boom. In this way, the high-pressure hose can be inserted directly into the boom arm of the telescopic boom, which further increases the working range of the vehicle.
  • the roller guide can be mounted to be longitudinally displaceable along the longitudinal axis of the vehicle. Such a shift would lead the high-pressure hose from the hose reel directly into the telescopic boom without touching the roller body of the rotary bearing.
  • the roller guide can preferably be displaced by the telescopic boom in the direction of the hose reel for the high-pressure hose, so that there is free space for further pivoting of the telescopic boom.
  • the roller guide can have a stop roller, through which the roller guide can be displaced through the telescopic boom.
  • the roller guide can be returned to its starting position, preferably by a restoring force.
  • This restoring force can in particular be a tension gas spring, a gas pressure spring or a pneumatic cylinder.
  • a sewer cleaning vehicle 10 has a chassis adapted to its maximum load.
  • a tank is located behind the driver's cab 12 of the vehicle 10 in a manner known per se.
  • the tank serves as a storage device to store extracted sludge.
  • other tanks or other containers could also be provided, for example to keep a supply of cleaning liquid.

  • Hose reel 22 and telescopic boom 30 can be coupled to one another in such a way that when hose reel 22 rotates about axis 26 , telescopic boom 30 is also pivoted about axis 26 .
  • the telescopic boom 30 has a telescopically designed boom arm 32 which is integrally formed on a guide element 34 at its vehicle-side end. Boom arm 32 and guide element 34 are arranged at an angle to one another, so that telescopic boom 30 has a kink 36 (see in particular 9 ).

  • the high-pressure hose 42 is wound off and onto the hose reel 44 approximately in the longitudinal direction 14 of the vehicle 10 .
  • the hose reel 44 is arranged below the level of the roller bodies 40, so that the high-pressure hose 42 has to be guided a little way up out of the vehicle body.
  • the high-pressure hose 42 is routed via a roller guide 46 which is fastened to the rotary bearing 20 .
  • the roller guide 46 can prevent the high-pressure hose 42 from being guided over an edge of the rotary bearing 20, which could lead to damage and the opening and closing Unwinding would be particularly difficult in the area of hose couplings.
