Definitions

  • the front boom is anchored to the front of the drive machine so that it can be pivoted to both sides, that is to the right and left of the drive vehicle, and it is also set up so that its arms can be pivoted hydraulically.
  • attachments such as flail mowers, verge mowing heads, washing devices for guide posts, tree cutters and others are exchangeably fastened, the attachments being hydraulically driven and the arms of the front boom being brought into the respective operating positions by the hydraulic adjusting devices.
  • a washing device for road signs is known according to the preamble of claim 1, which is attached to the rear of a vehicle.
  • the vehicle carries a tank for cleaning fluid.
  • a first arm is articulated on the vehicle.
  • the first arm can be pivoted with respect to the vehicle by means of an actuating device operated by pressure medium.
  • a second arm is articulated on the first arm.
  • the second arm can also be pivoted with respect to the first arm by a pressure medium-operated adjusting device.
  • a washing head is attached to the free end of the second arm.
  • the washing head contains a carrier and a shaft mounted therein which carries a washing brush arrangement.
  • the shaft and the washing brush arrangement can be driven by a hydraulic drive motor with variable speed.
  • the washing brush arrangement is assigned a spray device which is connected to the tank for cleaning liquid.
  • the shaft runs essentially perpendicular to the road traffic sign to be washed.
  • the wash brush arrangement is a disk-like wash brush arranged perpendicular to the shaft.
  • Such a disc-like washing brush only covers a relatively small area of the road traffic sign.
  • the washing brush with two degrees of freedom must therefore be passed over the road traffic sign in rows or columns. This requires special attention and skill on the part of the user.
  • the invention has for its object to provide a washing device of the type mentioned in such a way that it allows the rapid cleaning of large road traffic signs, such as highway signs, without special demands on the attention and skill of the user.
  • washing device can be used instead of e.g. B. a verge mowing head to a front boom of a vehicle.
  • the wash brush arrangement covers a wide strip, so that the entire road traffic sign can usually be painted over in one pass. It is ensured that a predetermined orientation of the washing brush arrangement is always ensured despite the pivoting movement of the arms.
  • Embodiments of the invention are the subject of claims 2 to 15.
  • FIG. 1 shows a front view of a front boom with a washing device, in particular for motorway traffic signs.

  • the carrier 17 has a raised stop 23 with guide surfaces for receiving the free end 16.
  • the replacement of the washing device for another implement is relatively simple and quick in that the pin 14 is released from the connection of the second arm 12 and the socket 11 to the holder 3 and the second arm 12 is removed from the socket 11. Then the corresponding arm of the other, in each case the desired implement is inserted into the socket 11 and this is fastened to the holder 3 with the respective fastening device.
  • a rope 30 is provided, which is guided from the anchorage 2 via three rope guides and is fastened to the third rope guide.
  • the cable guides form sectors 31, 32, 33, which are arranged at their centers on the front boom and along the circumferential surface of which the cable 30 is guided between upstanding edges.
