Definitions

  • the invention relates to a five-armed concrete placing boom arranged on a vehicle with a first mast arm 1 arranged on a front axle on the vehicle and rotatable about a vertical axis on a horizontal swivel joint A, with articulated joints B, C, D, E in pairs against each other the previous mast arm can be folded in a substantially parallel orientation, further second, third, fourth and fifth mast arms 2, 3, 4 and 5 lying in the driving position under the first mast arm 1, and with tubular rotating couplings that extend along the individual mast arms and are parallel to the articulated joints interconnected pipe sections of a concrete to which a delivery pipe leading to the free end of the fifth mast arm 5 is connected to a pipe rotating coupling, the first and second mast arm 1, 2 and the second and third mast arm 2, 3 having a swivel range of approximately Knickge with 180 ° steer B and C in opposite directions in the manner of a Z-fold.
  • a concrete placing boom of this type is known (DE-PS 34 46 290), in which all boom arms 1, 2, 3, 4 and 5 can be folded against one another at their articulated joints B, C, D and E in the manner of a multi-Z folding.
  • This concrete placing boom has a long reach and can be used to advantage in low construction sites as well as in building construction.
  • the Multi-Z folding also ensures a quick operational readiness after only a short lifting of the partially unfolded Arm packs and a high degree of flexibility, especially when concreting hard-to-reach places, whereby dead spaces are largely avoided both when lifting the vehicle close to the vehicle and when concreting in low rooms.
  • the articulated joints C and E near the front axle have a swivel range of 270 ° between arms 2 and 3 or 4 and 5, while the other articulated joints B and D have a swivel angle of 180 °.
  • Concreting parallel to the working level is possible with the Multi-Z folding.
  • bringing the end hose up to the driver's cab must be bought with a relatively high unfolding height.
  • the invention is therefore based on the object to develop a concrete placing boom of the type mentioned, which can be used both in ground-level, lower rooms while overcoming obstacles and in higher floors for concreting with parallel hose routing and the lowest possible unfolding height.
  • the third and fourth mast arm and the fourth and fifth mast arm at their articulated joints D and E are each foldable in the same direction as the second and third mast arms 2 and 3 in the region of their articulated joint C in the manner of a roll fold .
  • the mast arm 2 in addition to a guiding function for ground-level concreting, also has an outreach function that allows obstacles to be overcome in the ground-level area and over several floors, while the subsequent mast arms 3, 4 and 5 alone (without the arm 2) enable a parallel hose guide with a low unfolding height from its extended position to the obstacle to be overcome.
  • the articulated joint D and / or the articulated joint E has a swivel angle of approximately 270 °.
  • the truck-mounted concrete pump shown in the drawing has a chassis 10, a pivot bracket 16 arranged in the vicinity of the front axle 12 and the driver's cab 14 of the chassis 10, a distributor mast 20 rotatable on the pivot bracket 16 about a vertical axis 18 through 360 °, and a material feed container 22 concrete, hydraulically driven concrete pump 24 and a delivery line 28 connected to the concrete pump 24 via a pipe switch 26.
  • the placing boom 20 has five boom arms 1, 2, 3, 4 and 5 which are connected to the pivot joint A with the pivot bracket 16 and the articulated joints B, C, D and E are connected to each other.
  • the folding in and out of the mast arms 1 to 5 around the joints A to E is carried out hydraulically by means of double-acting hydraulic cylinders 30, which are articulated with their free cylinder-side and rod-side ends to arms or folding brackets of the mast arms 1 to 5 and the pivot bracket 16.
  • the swivel joint A has a swivel range of 90 ° to 100 °, the articulated joints B and C of approximately 180 ° and the articulated joints D and E of approximately 270 °.
  • the mast arms are folded against one another in an essentially parallel orientation, the mast arms 2, 3, 4 and 5 coming to rest under the base arm 1.
  • the mast arms 1, 2 and 3 are folded in opposite directions at their articulated joints B and C in the manner of a Z-fold, while the mast arms 3, 4 and 5 at their articulated joints D and E are each in the same direction as the mast arms 2 and 3 are folded against each other like a roll fold.
  • FIG. 2a and b illustrate the mode of operation when concreting the floor at ground level in low rooms, in particular in a factory building 32.
  • the mast arms 2 to 5 are first pivoted with the base arm 1 slightly raised in the downward position by turning the pivot bracket 16 in front of the driver's cab 14 and lowered to an inclined position so that passage through the lower entrance gate 34 of the factory hall 32 is possible (FIG 2a left).
  • the arm assembly 2 to 5 can be set up inside the factory hall 32 and concrete can be applied while filling the delivery line (FIG. 2a on the right).
  • the concreting of the floor is started at the point furthest away from the vehicle, namely via the flexible end hose 36 hanging down at the free end of the mast arm 5, which is directed by the operator to the locations to be concreted.
  • the end hose can be moved along a working line L parallel to the floor up to directly in front of the driver's cab 14. Due to the special arrangement and swivel ranges of the articulated joints B to E, the unfolding height H is only slightly higher than the working line L traversed by the free end of the end arm 5. Only a few simpler are then required from the end position of the end hose 36 near the driver's cab shown in FIG. 2b Sequences of movements in order to bring the mast arms 2 to 5 into their folded position shown on the right in FIG. 2a.
  • the truck-mounted concrete pump described can also be used for tunnel concreting if the end arm 5 is additionally equipped with a hydraulically and / or motor-operated end hose manipulator 40.
  • the end hose manipulator 40 can be connected to the last pipe section 46 of the end arm 5 of the concrete placing boom 20 via a rigid pipe section 42 and a pipe rotating coupling 44.
  • the pipe section 42 has at its front end a support structure 58 on which a pipe section 42 in substantially axially parallel hydraulic cylinder 48 is pivotally mounted.
  • the flexible end hose 36 is connected, which carries in its end third a sleeve 50 designed as a clamping bracket, which is provided with lateral pivot bearings 52 to which the fork-shaped load arm 54 of a two-armed pivot lever 56 is articulated.
  • the pivot lever 56 is pivotally mounted at the end of an essentially axially via the support structure 58 of the pipe section 42 about an axis 60 parallel to the pivot bearings 52 and is connected to the piston rod 64 of the hydraulic cylinder 48 at its power arm 62 which is angled with respect to the load arm 54.
  • the pivot lever 56 can be pivoted in an angular range of approximately 60 °.
  • a housing 66 is arranged on the pipe section 46 for receiving a hydraulic motor 68, the drive shaft 70 of which can be coupled to the pipe section 42 via a chain drive 72.
  • the pipe section 42 can be rotated by motor in relation to the pipe section 46 in any rotational position.
  • the rotation and tilting movement of the end hose 46 takes place by hydraulic control of the hydraulic motor 68 and the hydraulic cylinder 48 via the control valves 74 arranged in the housing 66 with the aid of a remote control (not shown).
  • the end hose 36 can thus be actuated by corresponding actuation of the distribution mast 20 and the end hose manipulator 40 are successively connected to the concreting nozzle or window 76 of a tunnel formwork 78.
  • the invention relates to a five-armed concrete placing boom 20 arranged on a vehicle, the mast arms 1, 2 and 3 of which, at their articulated joints B and C having a pivoting range of approximately 180 °, can be folded in opposite directions in the manner of a Z-fold.
  • the mast arms 3, 4 and 5 on their joints D and E which have a swivel range of approximately 270 °, each have the same direction as the mast arms 2 and 3 in Area of their articulation C are foldable against each other in the manner of a roll fold.
