Definitions

  • the invention relates to a rotary distributor for thick matter, in particular for fresh concrete, with a supporting frame which is mountable on a mounting surface, with a first extension arm tube which is arranged in the region of the input-side end thereof on the supporting frame so as to be rotatable about a frame-mounted vertical axis and is chargeable there under pressure with the thick matter, and with a second extension arm tube which is arranged in the region of the output-side end of the first extension arm tube so as to be pivotable about a horizontal pivot axis and communicates with the first extension arm tube.
  • Rotary distributors customarily consist of a two-part extension arm, a counter-extension arm with ballast and a supporting frame which is generally configured as a standing base.
  • the two extension arm tubes of the two-part extension arm are customarily connected via a joint which only permits rotation about the vertical axis.
  • Rotary distributors can therefore move only in the horizontal plane. While, for safety reasons, because of the great working height in the case of distributing booms, the boom arm is always composed of a supporting structure and a delivery line connected thereto, the second arm of a rotary distributor generally consists only of a self-supporting delivery tube. Rotary distributors customarily do not have a drive, but rather are guided manually by the operator. They are relatively favorably priced because of their simple design and because of their small reach. They are therefore preferably used for simple concreting tasks.
  • the scissors-like mobility of the second extension arm tube in relation to the first extension arm tube has the advantage that, in contrast to distributing booms, the rotary distributors are highly suitable for concreting areas.
  • the invention is based on the object of improving a rotary distributor of the type indicated at the beginning to the effect that the working region thereof can be expanded and possible obstacles at the building site can more simply be avoided.
  • the solution according to the invention is based especially on the concept that a rotary distributor with a raisable first extension arm tube, the entire extension arm, can be pivoted in a simple manner beyond obstacles and a laborious repositioning of the rotary distributor is dispensed with.
  • the first extension arm tube is additionally pivotable in the region of the input-side end thereof about a horizontal axis in addition to the vertical axis of rotation in relation to the supporting frame. If, in this case, the joint between the two extension arm tubes were to be provided, as is customary, only with a horizontal axis, the second extension arm tube would be inclined when the first extension arm tube was raised.
  • the second extension arm tube is additionally rotatable about an axis of rotation, which is perpendicular to the horizontal pivot axis, in relation to the output-side end of the first extension arm tube, and that parallel guide means are provided between the first and the second extension arm tube, which parallel guide means are intended and suitable
  • the guiding of the second extension arm tube parallel to the mounting surface can be realized, for example, by means of two tensioning elements which connect the joint of the first extension arm tube to the joint of the second extension arm tube.
  • the first extension arm tube is connected to a frame-mounted tube length via at least two tube bends and a corresponding number of tube couplings, wherein two of the tube couplings are configured as rotary couplings with axes of rotation aligned perpendicular to each other.
  • one of the rotary couplings forms the vertical axis
  • the other rotary coupling forms the horizontal axis, of the first extension arm tube in relation to the supporting frame.
  • a similar construction can be used for the connection of the first and the second extension arm tube.
  • the second extension arm tube is connected at the input-side end thereof to the output-side end of the first extension arm tube via at least two tube bends and a corresponding number of tube couplings, wherein two of the tube couplings are configured as rotary couplings with axes of rotation aligned perpendicular to each other.
  • one of the rotary couplings forms the horizontal pivot axis
  • the other rotary coupling forms the axis of rotation, which is perpendicular to said pivot axis, between the first and the second extension arm tube.
  • ballast extension arm which rotates together with the first extension arm tube about the frame-mounted vertical axis is arranged in the region of the input-side end of said first extension arm tube.
  • the first extension arm tube is pivotable about the input-side horizontal axis thereof by means of a lifting apparatus with the second extension arm tube being raised or lowered in relation to the supporting frame.
  • the lifting apparatus here can have a tensioning or tension member which is clamped between the extension arm tube and the ballast extension arm and is mechanically actuatable by the first extension arm tube being pivoted about the horizontal axis thereof.
  • the lifting device advantageously has a lever which is coupled to the ballast extension arm or to the web of the four-bar linkage mechanism, is movable via a drive mechanism and the free lever end of which is connected to the first extension arm tube via the tensioning or tension member.
  • the lifting apparatus has a two-armed lever which is arranged on the ballast extension arm, and the load arm of which is connected to the first extension arm tube via the tensioning or tension member and the force arm of which is coupled to a drive mechanism which is supported on the ballast extension arm and is preferably configured as a hydraulic cylinder.
  • a drive mechanism which is supported on the ballast extension arm and is preferably configured as a hydraulic cylinder.
  • FIG. 1 shows a rotary distributor with a two-armed extension arm and an end hose
