Definitions
- the invention relates to a distributor device according to the preamble of claim 1.
- Such distribution devices are known ( EP 432 854 and WO 00/24988 ). These have a telescoping mast section, which is articulated on a turntable for the distributor and is pivotable via a working cylinder from a horizontal transport or rest position to a iw vertical working position. About this turntable, the distribution boom is mounted on a suitable transport vehicle, such as truck or crane truck. These distribution booms are used for receiving delivery lines, in particular for concrete, and are used mainly for the distribution of concrete for the construction of building ceilings and the like.
- the telescopic mast section of the distributor boom carries the concrete conveyor line, which must be tracked during extension of the telescopic part.
- pipe shears are known, which are formed from pivotally interconnected pivot pipes. If the movable telescopic part extended, the pivot tubes are pivoted like a scissor, the ends of the pivot tubes run with their hinge points past each other and therefore can follow the concrete conveyor line of the telescopic movement.
- US 4 130 134 A describes a device having the features of the preamble of claim 1.
- the object of the invention is to provide a distribution device with a telescopic mast section with a compact design and good load distribution, which is characterized by high stability.
- a concrete conveyor line in the region of the telescopic mast section receiving supporting support which connects the two telescopic parts together and this is connected at one end to the extendable telescopic part and with its other end to the relatively fixed other telescopic part, so both telescopic parts so to speak coupled together and that both in transport position as well as in the conditional by corresponding extension movement of the movable telescopic part intermediate positions which define the working positions.
- the concrete conveyor line is arranged on both sides in the region of the telescopic mast section, ie the leading part of the concrete conveyor line is on one side of the mast section and the tube scissors and the wegphasede part of the concrete delivery line, which leads to the Verteilermastspitze, arranged in the region of the telescopic mast section on the other side.
- the support beam is formed of a bending and torsion beam, in particular designed as a hollow profile.
- the joints of the pipe shears d. H. the joints where the ends of the pipe cutter are connected to each other with the leading and away concrete conveyor line and the pivot tubes of the scissors are suitably designed as rigid pipe rotary joints, which is in view of the pump strokes occurring during the operation when Pumphub lymph advantage. This also contributes to the stable construction of the distributor device.
- the drive cylinder is articulated for the hinged to the telescopic mast section folding mast section in the region of the front end of the telescopic telescopic part via a conventional articulated linkage, but fixed with its other end on the foldable mast section, which has the advantage that the Teleskopierweg maximally used is reduced, in particular not according to the conventional design to the full cylinder length, since there the working cylinder is usually articulated on the previous mast section.
- the outer telescopic part can be brought up to the articulated linkage. It is an expedient development, but also to a superordinate and own invention principle independent of the support beam assembly between the two telescopic parts, which can be used with advantage in other circumstances.
- Another advantage is the telescoping mast section in conjunction with hinged thereto further foldable mast sections, because in this way the distribution boom has improved slip characteristics, so the threading of the mast tip is facilitated in windows or other masonry openings. This makes the distribution boom at the same time particularly advantageous for use on construction sites with limited free working height, such as in halls.
- the in the Fig. 1-3 distributor boom 1 shown is usually arranged with its turntable 2 on a mobile pedestal, such as a truck or a mobile crane truck, or mounted stationary as needed.
- the distributor boom shown here has a telescoping mast section 4 articulated here on the slewing ring 2 at 3, which is formed from a first and fixed telescopic part or outer telescopic part 5 and an inner second telescopic part 6 displaceable therein.
- the telescopic mast section 4 is in this case from a horizontal, in Fig. 2 shown transport position by means of a working cylinder 7 by an angle to about 90 ° pivotable into a working position, as in Fig. 1 is shown.
- the working cylinder 7 is articulated on a bracket 8 protruding from the turntable 2 and engages a console 9 arranged on the outer telescopic part 5.
- the upper and the Verteilermastspitze facing the end of the extendable telescopic part 6 is equipped with an angle bracket 10 to which a further, foldable mast section 11 is articulated.
- a mast section 12 and at this finally a third foldable mast section 13 is articulated, which forms, so to speak, the Verteilermastspitze.
- the concrete delivery line attached in the Fig. 1-3 to simplify the illustration is not shown in the drawing. This concrete delivery line ends with a proboscis on the Verteilermastspitze 14 and can be moved by appropriate extension and pivoting of the distributor boom in any working positions for the distribution of the conveyed concrete.
- the mast sections 11 and 12 are folded by means of a so-called Z-folding, whereas the outermost mast section 13 by means of a so-called roll-folding is collapsible.
- This folding is off Fig. 2 seen. This is in detail for the transfer to the transport position Fig. 2 the mast section 11 through the working cylinder 15 in the off Fig. 1 indicated arrow direction pivoted, however, the mast section 12 and the mast section 13 in the direction indicated by arrows. From the representation of Fig. 1-3 is removable that it requires the purpose of a compact construction of a precise tuning of the moving parts, in particular for this purpose, an arrangement of concrete delivery line is suitable, which is described in more detail in the following figures.
- the concrete delivery line is in this case usually formed of composite pipes in the manner of a pipeline, but can also be wholly or partially formed from a tubular hose his
- the concrete conveyor line 17 is flanged in the region of the turntable 2, so that they also usually on the truck or the crane arranged concrete pump, usually a double-cylinder pump, for thick materials, especially concrete, can be supplied.

- Fig. 7 It also follows that the pivot tube 20 S-shaped and the pivot tube 19 is C-shaped. This is advantageous for a structurally compact arrangement of the concrete delivery line.
- the two C-legs of the pivot tube 19 open into the joints 21 and 22, whereas the ends of the pivot tube 20 in S-shape in the joints 21 and 31 open.
- the pivot tubes of the tube scissors 18 are pivoted so that the articulation points cross over each other, so that the concrete conveyor line in the region of the telescopic mast section of the export movement of the Telescopes can follow.
- the feeding conveyor line section 32 is arranged on the opposite side of the first telescopic part 5, on which the support beam 24 is arranged.
- the concrete conveying line is located both on one side and on the other side of the mast section 4.
- the joints 21, 22 and 31 of the pipe cutter are designed here as rigid pipe rotary joints, as shown schematically in the Fig. 7 is clarified with respect to the joint 31.
- the tube ends of the adjoining joints in the tube can be rotatably received in a socket.
- the pipe ends are reinforced by a welded or otherwise applied cuff.
- Fig. 13 an embodiment of a suitable pipe pivot bearing is shown and that on the hand of the joint 31, which is arranged below the telescopic part 5.
- the end of the advancing conveying line section 32 is in this case formed in a flange-like manner at 36 and adjoins a corresponding bearing tube 37 with a flange-like design on both sides, wherein the coupling takes place via a sleeve 38 shown only schematically.
