Definitions

  • the invention relates to a mobile concrete pump with a directly or indirectly via a body frame mounted on a chassis of a truck chassis support structure which receives a support device and a distribution boom forming functional units, wherein the distribution boom is rotatably mounted on a mast block, which inserted one into the support structure , as a pivot bearing for the distribution boom equipped boiler comprises and wherein the supporting device comprises two integrated in the support structure, diagonally forward open, intersecting Stauerbeinhimsten and each one in the support leg boxes telescopically arranged support leg.
  • the support structure is mounted on a body frame and placed together with this on the chassis of a truck chassis.
  • the support structure forms with its mast block and the support leg boxes the interface between the distribution boom and the support legs.
  • the load moment caused by the distribution boom is distributed over the girder and the support leg boxes on the support legs and introduced into the ground.
  • Particularly popular with mobile concrete pumps is a support structure that is equipped with two telescopic support legs at the front and two swing-out support legs at the rear.
  • the support leg boxes of the front support legs form an "X" in this construction, so they cross each other diagonally in the support structure.
  • the point of intersection of the two support leg boxes would be ideal for introducing the load moment of the distributor mast into the support legs by the shortest route, ie if the boiler was mounted at the crossing point as the carrier of the distributor boom.
  • the boiler is therefore usually located in the direction of travel in front of the support leg boxes. The deflection of the power flow from the eccentric boiler in the bearing vertical side walls of the support leg boxes but only possible with a considerable design effort. Accordingly, this construction forces the use of heavy and structurally complex mast stands.
  • EP1847505 A2 discloses a mobile concrete pump according to the preamble of claim 1.
  • the present invention seeks to make the boiler of the girder so and position it in the support structure that even with a lightweight design optimal load transfer from the distribution boom to the support legs is possible.
  • the support structure has an upwardly open, parallel to the axis of rotation of the distribution boom aligned polygonal opening and that the boiler of the mast block has adapted to the polygonal opening polygonal outline and is inserted into the polygonal opening of the support structure.
  • This makes it possible that the boiler is aligned with two of its side surfaces parallel to a side wall of each one of the support leg boxes. If the boiler is also integrated with two of its side surfaces in the respective side walls of the support leg boxes in alignment, with a compact design, an optimal force transmission between mast support and support leg boxes is achieved.
  • a preferred embodiment of the invention provides that the boiler is flanged to the support structure in the region of the polygonal opening and the support leg boxes and / or welded into this.
  • the boiler forms a column of multi-folded sheet metal. This will be So two boiler side surfaces and two side walls of the support leg boxes united into one component. The power flow does not occur so directly over this common structure, as if the boiler sat in the crossing point.
  • the construction according to the invention is, however, largely free of deflection.
  • a further advantageous embodiment of the invention provides that the boiler in the region of its upper edge has a standing in operative connection with the distribution boom rotary drive.
  • the diagonally extending support leg boxes are expediently designed in such a way that they have telescopic tubes arranged at different heights within the support structure for the support legs and through an intermediate floor of these separate free spaces.
  • the boiler of the girder is in the central area on the intermediate floor, wherein in the intermediate floor, a central opening for the passage and / or for the rotary feedthrough of conveying, control and power lines is arranged.
  • the polygonal opening may have on its side facing away from the support leg boxes an edge opening through which the boiler partially reaches through to the front side.
  • the intermediate bottom bearing the vessel expediently has a reinforcement zone formed by bending deformation and / or by structural elements in the region of the central opening.
  • the truck chassis 10 carries a concrete pump 20 which is connected via a body frame 22 to the chassis 12.
  • the concrete pump assembly essentially comprises a core pump 24 with two hydraulic drive cylinders 26, two in pairs connected to the drive cylinders 26 via a water box 28 feed cylinders 30 and a rigidly arranged at the other end of the feed cylinder 30 material feed container 32.

As in particular from the Fig. 4a to c can be seen, the boiler 52 forms a column of multi-folded sheet metal.
  • the boiler 52 is welded in the support structure 46 in the region of the polygonal opening 50 and the support leg boxes 54, 56.
  • the diagonally extending support leg boxes 54, 56 are formed in such a two-story, that their arranged at different heights within the support structure 46 telescopic tubes bound by an intermediate bottom 72 of these separate spaces 74.
  • the intermediate bottom 72 is provided there with a central opening 76 for the passage and / or for the rotary feedthrough of conveying, control and power lines, not shown.
  • the intermediate floor 72 has a reinforcement zone 80 formed by bending deformation and by structural elements 78, which receives the vertical load of the distributor boom 36 and deflects it via the support structure 46 onto the support legs 40, 66.
  • the polygonal opening 50 has an edge opening 82 on its front side remote from the support leg boxes 54, 56, through which the boiler 52 partially reaches.
  • the boiler 52 has a rotary drive which is in operative connection with the distributor boom and whose bearing 84 is in Fig. 4a to c you can see.
