Definitions

  • the invention relates to a foldable, transportable placing boom which can be rotated about a vertical axis, which carries a concrete delivery pipe and which consists of a plurality of articulated mast parts.
  • a concrete pump is generally built into a transport vehicle, too. carries a placing boom for the concrete delivery pipe to bring the concrete to the processing site. For reasons of transport, it is necessary to assemble the placing boom from several parts which are connected to one another in an articulated manner and wherein adjusting devices are provided in the area of the joints in order to fold up or erect the placing mast.
  • Such a placing boom is described, for example, in DE-PS 2 000 382.
  • the mast parts lie one above the other, the folding being possible, for example, in the manner of a roller fold or also in the manner of a Z-fold.
  • the invention is based on a distributor lock of the type described in the introduction and suggests that two mast parts connected to one another are arranged next to one another in the region of the connecting joints and the concrete delivery pipe is guided through the articulated bearings.
  • a placing boom for the purpose in question has such a design that it is essentially symmetrical to a vertical central plane
  • the invention proposes a construction in which two connected mast parts are arranged next to one another in the area of the connecting joint.
  • mast parts connected to one another with essential parts lie next to one another. It is clear that almost double the amount of mast parts can be accommodated on a transport vehicle in this way in the folded state, since the individual mast parts, so to speak, on two. Stacks are transported side by side.
  • the invention also solves the problem of collapsing the concrete delivery line in that the concrete delivery line is passed through the articulated bearings. It has been found that the resulting curvatures do not bring any significant disadvantages either structurally or for concrete delivery. However, the considerable advantage is gained that the concrete delivery line can easily be brought into any desired position without difficulties occurring at the points in which the individual pipe parts move relative to one another.
  • the individual mast parts and the associated devices can be largely of the same design, which considerably simplifies production.
  • the construction of the single mast is simple in itself.
  • the type of merging does not require any bends in the area of the joints. In general, it is sufficient if the individual.
  • Mast parts are arranged side by side in the folded state in two vertical levels. In special cases, however, it is not excluded to form more than two "stacks".
  • the connecting joints between two mast parts are arranged in the central plane of the mast parts and the adjusting device is arranged on that side of the mast parts which is the upper side in a horizontal working position.
  • the invention takes advantage of the fact that expensive bends on the individual mast parts are unnecessary. If all the adjustment devices are arranged on the top, the risk of getting caught on components with the placing boom or damaging the adjustment devices is also reduced.
  • Another advantage of the design according to the invention results from the fact that the passage of the concrete delivery line through the connecting joints on the one hand requires a corresponding dimensioning of these joints, which, however, are in turn well able to absorb the bending and torsional forces occurring in the construction according to the invention.
  • the invention further proposes that the end piece of the concrete delivery pipe hangs on a pipe bend which is rotatable about a horizontal axis in a rotating coupling and rests in a guide part of a mast part in the transport position.
  • the part of the concrete delivery pipe assigned to a mast part prefferably be arranged in parallel next to the mast part. It is easily possible to keep the distances of the concrete delivery pipe from the mast part the same for all mast parts, so that the same connection and fastening means can be used between the concrete delivery pipe and the mast part.
  • the design according to the invention can be applied with a Z-fold upwards, but also with a roll fold downwards.
  • the adjustment devices are to be arranged accordingly.
  • the invention further relates to an advantageous embodiment of the fastenings of the concrete delivery pipe on the mast parts, which facilitates assembly and disassembly.
  • Elastic inserts in the brackets ensure that no shocks or constraining forces are transmitted to the supporting structure.
  • the pump unit 2 is installed inclined over the drive axles of the chassis 1 in order to obtain the lowest possible filling edge in the feed hopper 3.
  • the discharge line 4 runs, for example, laterally or also via the feed hopper 4 to the placing boom, which consists of the mast parts A, B, C and optionally D.
  • the axis of rotation 8 of the placing boom allows rotation, for example by 360 °. It is located near the cab.
  • the subframe 6 of the pump which is part of the support frame 5 of the placing boom, is anchored on the vehicle frame and the. Extension supports 7 required in the operating position are mounted on the support frame 5 and are pivoted onto the chassis for transport.
  • Stand part 10 (see Fig. 3) carries in shape via a slewing gear. the bearing head with the main bearing 10 of the mast part A.
  • the placing boom can be rotated about the axis 8 by means of the rotary drive 9.
  • mast part A in the exemplary embodiment according to FIG. 1.
  • the mast parts B, C and D which are articulated by means of the joints 40 or 41 and 42, can only be shorter than the mast part A in the exemplary embodiment according to FIG. 1. It is clear that a corresponding number of for a certain range Mast parts are required.
  • the basic height ho of the pump unit determined by the overall height of the hydraulic cylinders or the control on the feed hopper side, forms the lower limit for boom parts, while the upper limit is formed by the permissible transport dimension.
  • the resulting overall center of gravity S, SI of the folded boom has a strong influence on the choice of the chassis and its wheelbase and vice versa. For example, if the overall center of gravity of the pump with the boom is too far to the rear, then the driving and in particular maneuvering conditions are impaired by front axle relief or chassis with an extended wheelbase are required.
  • the construction of a placing boom according to the invention can be used for any folding method.
  • the mast part A is rotated by 12 by hydraulic cylinders 13 by an angle ⁇ .
  • This main adjusting cylinder is expediently effective as a pressure cylinder from below.
  • Mast parts B, C and others are each pivoted by ⁇ via hydraulic cylinders 14/15, angle levers / handlebar combinations 16.
  • the mast parts overlap at least partially in the side view, as shown in broken lines in FIG. 3.
  • the hydraulic cylinder with angle lever and handlebar are shown in Fig. 3 u. 4 arranged on top of the mast parts and in a plane between the axes of the mast parts. This arrangement also applies to all other mast parts that are not shown. In the operating position, the jacks sit on top of the mast parts.
  • Hydraulic cylinders, angle levers and handlebars are only attached to masts A and B at the bottom for Z-folding; all other moving parts of mast part C and other mast parts, not shown, are in the unfolded state again at the top. This results in a completely free and accident schu t zw i rk same lower edge of the vehicle remote from the mast parts.
  • the axis of the concrete delivery line lies with the M axis (X-axis) of the associated mast part in the same horizontal plane.
  • the horizontal center distance is expediently kept the same for all mast parts, so that uniform elements for the bracket can be reached.
  • the concrete delivery line 25 is passed through the mast profile and ends in a pipe bend 24, rotatable ir, a rotary coupling 31, so that the subsequent elastic end distributor hose 29 always hangs vertically. If the end distributor hose or the connecting pipe bend is possibly caught on the building, these parts swivel out around the horizontal axis.
  • the horizontal distance of the end distributor hose 29 from the system axis M of the last mast part is approximately equal to the horizontal offset of the last two mast parts, so that the end distributor hose 29 comes to rest on the cover surface or at least part of the cover surface within a hose guide 32.
  • the 7 consists of the bearing tube 17, which is welded into the stronger mast part.
  • the bearing tube has an end abutment surface 19 on which the hub of the neighboring boom comes to rest.
  • the weaker mast part is guided over the bearing bush 20 on the bearing tube and secured by ring 21.
  • the bearing tube 17 is dimensioned so that the conveyor tube intermediate piece can be easily carried out. Expediently, one half of the shell coupling 22 is elastically attached to the mast part between the conveyor tube intermediate piece and tube bows 24.
  • A. straight concrete delivery pipe 25 lying in the X-axis plane is held next to the pipe bend 24 in a single holder.
  • This consists of a fixed shell part 26 which is attached to a tubular support 28 in an adaptable manner.
  • the hinge-like shell part 27 provided with a clamping lever, quick assembly and disassembly of the delivery pipes is possible.
  • the shell parts carry elastic inserts 29, which exclude tension, so that the coupling points are closed more tightly and bumps. Do not forward noises.
  • the fixed shell bearing parts are attached to the mast part according to the invention by means of elastic brackets 33.
  • Level E of the adjusting device consisting of adjusting cylinder, angle lever and handlebar, lies between the mast part axes M.
  • the bearing blocks on the mast parts are identified by 18.
  • Fig. 8 the implementation and mounting of the delivery line through the bearing tubes 17 is shown in vertical section.
  • bracket of the conveyor tube 25 from a fixed shell bearing part 26 with an angle range of over 180 ° is also shown in a side view.
  • the end distributor hose 30 hanging on the last pipe bend 24 rotates in the rotary coupling 31 about a horizontal axis and, when folded, lies down in a hose guide 32 on the adjacent mast part.
