Definitions

  • the invention relates to a brush boom for tunnel washing vehicles, the working length of which is adjustable and which can be pivoted at one end on a holder of the vehicle about a vertical axis and about a transverse axis thereof, points backwards from the holder, pivoting about these axes at an acute angle to the vehicle is extendable into the working position and carries at its free end a roller brush that can be pivoted about its longitudinal axis and rotatable about a transverse axis.
  • the brush is adjusted to a specific strip of the tunnel wall with the help of the brush arm by swiveling around the two axes on the holder and usually with the aid of a hydraulic or pneumatic cylinder / piston unit with an adjustable center that serves for swiveling about the vertical axis pressure against the wall.
  • a control device is known which enables precise setting of the contact pressure and rapid evasion of obstacles by swiveling back the brush arm.
  • the brush can be freely pivoted about the longitudinal axis of the arm.
  • the described construction of the brush arm has proven itself in practice when cleaning tunnels of normal height, for example up to 4.5 m.
  • tunnels with greater heights for example tunnels of city motorways and supporting walls, ceiling heights of 7 m and supporting wall heights of 8 m occur.
  • Difficulties arise when using a brush boom of the type mentioned at the outset when the booms are pivoted onto the vehicle in the transport position. Only in the case of very long vehicles does the boom not protrude too far back over the vehicle and additional supports for the boom are necessary during the transport journey.
  • a brush boom is known from DE-A-1 15 34 163, in which the boom is made in the manner of a mobile crane there are a plurality of arms articulated to one another by transverse axes, hydraulic cylinder-piston units being provided for the pivoting adjustment of the arms lined up around the joints.
  • the working length of the boom can be adjusted here by bending the arms towards each other to a greater or lesser extent.
  • the overall construction is extremely complex and a separate operator is usually used to operate the brush arm.
  • the object of the invention is to provide a brush arm of the type mentioned which, despite maintaining a simple construction and simple operability, is also suitable for use at large working heights.
  • roller brush is pivotable about the longitudinal axis of the boom via a hydraulic or pneumatic actuator, the boom being formed at least for the most part of its length by a pneumatically or hydraulically adjustable cylinder-piston unit.
  • This design makes it possible to adjust the length of the boom and the relative swivel position of the roller brush around the longitudinal axis of the boom from the driver's cab of the washing vehicle via a remote control, so that it is possible to precisely adjust the roller brush to the desired size even with changing crown heights of tunnels, underpasses, etc. Set strips without having to leave the cab and work on the boom itself.
  • the cylinder-piston unit forms one or the load-bearing component of the boom. Brushes can also be used, the focus of which is not on the longitudinal axis of the boom.
  • an overload clutch in a drive connection between the actuator and the roller brush such as a detent which triggers in the event of an overload coupling or a detent mechanism that triggers when overloaded.
  • the overload clutch prevents damage due to bending of connecting parts or overloading the actuator, for example if the roller brush strikes one end against a tunnel wall or against an obstacle, so that relatively large torques would be generated about the longitudinal axis of the boom.
  • a detent clutch or a detent mechanism has the advantage over a slip clutch that can also be used, that the starting position between the brush and the actuator can be easily restored by resetting the brush until it snaps in, given that the adjustment path of the actuator is usually limited.
  • the roller brush at the end of the boom can additionally be pivoted by means of an actuator about an axis arranged transversely to its axis of rotation and to the longitudinal axis of the boom and can therefore be adjusted exactly transverse to the washing direction, if necessary, even with the boom set steeply, so that the full brush length for the width of the Washing strip is effective.
  • this setting can also be used to shorten the effective brush length (width of the washing strip) if the tunnel is very strongly curved.
  • a further embodiment of the invention is simpler, according to which a servomotor which forms the actuator for pivoting the brush about the longitudinal axis of the boom and which drives a shaft running in the longitudinal direction of the boom, is rotatable but axially via the overload clutch slidably mounted in the bottom of the cylinder of the cylinder-piston unit supported on the vehicle mount and engages with an extension in a rotationally fixed but axially displaceable manner in the piston of the cylinder-piston unit.
  • the extension of the shaft can be a pro be filstab.
  • brackets on the vehicle for the usual brush booms according to AT-A-1 344 232 and the brush booms according to the invention, the cylinder of the cylinder-piston unit being fastened to these brackets.
  • the rotatability of these parts in relation to one another in the case of cylindrical pistons and cylinders is simultaneously used for the rotatable mounting of the brush about the longitudinal axis of the boom.
  • a washing vehicle 1 which is designed as a truck with tank 2.
  • a standing column 3 is provided on the vehicle, which can be remotely rotated about its vertical axis via a hydraulic or pneumatic drive (not shown).
  • a hydraulic or pneumatic drive (not shown).
  • this pillar 3 carries a transverse axis 4, around which a z.
  • B. channel-shaped support piece 5 by means of a hydraulic or pneumatic piston drive, also not shown, which is supported with the second end on the column 3, can be pivoted up and down.
  • the boom consisting of a cylinder-piston unit 6, 7, shown shortened in FIG. 2 of the drawing, can be pivoted out into an operating position at an acute angle to the washing vehicle 1 while pivoting about the axis determined by the column 3 and about the transverse axis 4. If necessary, a single washing vehicle can be equipped with one or more brush arms on corresponding columns 3.
  • the cylinder 6 has a reinforced base 8 and is in the vicinity of this base 8 with the support piece 5 around Axis 4 swiveling.
  • the piston 7 of the cylinder-piston unit consists of a tube with a stepped outside, the stepped part 9 allowing the cylinder 6 to be extended up to the stop determined by paragraph 10.
  • the cylinder spaces 13, 14 lying on both sides of an end collar 12 of the piston 7 provided with a seal 11 can be acted upon hydraulically via lines (not shown) and shut-off elements which can be operated remotely from the driver's cab of the washing vehicle 1 in the direction of retraction or extension of the piston 7.
  • a support plate 15 on which a brush holder 17 can be pivoted about a transverse axis 16, the pivoting position of the brush holder 17 being adjustable by means of a hydraulic actuator 18 which can also be operated remotely.
  • the brush holder 17 can form a fork in a known manner, between the ends of which a roller brush 19 rotatably supports parallel to the holder 17.
  • a hydraulic motor 20 can be provided for driving the roller brush 19.
  • the brush holder 17 can also carry spray nozzles for the supply of washing and rinsing liquid to the brush area.
  • the piston 7 is rotatably supported in the cylinder 6 about the longitudinal axis.
  • a hydraulic servomotor 21 is used which drives a detent coupling 23 via its shaft 22, in which two disks are pressed against one another by a spring 24 and these disks are recesses for have the common inclusion of balls 25. If a torque predetermined by the setting of the spring 24 is exceeded, then the two disks of the detent coupling 23 can rotate when the balls 25, which are preferably contained in a cage, emerge from the detent recesses. After such a rotation, the brush holder 17 with the brush 19 again in the off pivoted backwards position, then the locking is restored.
  • An output shaft 26 of the clutch 23 is rotatable, but axially immovable in the bottom 8 of the cylinder 6.
  • the motor 21 is supported with its housing on the holder 5, but can also be fastened to the bottom 8 of the cylinder 6.
  • the shaft 26 has an extension designed as a profile shaft, spline shaft or profile rod 27, with which a bottom part 28 of the piston 7, which has a corresponding opening, is displaceable but non-rotatably engaged, so that the piston 7 rotates from the servomotor 21 via the clutch 23 and so that the brush holder 17 can be pivoted with the brush 19 about the longitudinal axis of the boom.
