Definitions
- the invention relates to a five-arm concrete placing boom arranged on a vehicle, having a mast arm 1, which is arranged on a front axle on the vehicle on the front axle and can be rotated about a vertical axis, on a horizontal swivel joint A, with a boom arm on articulated joints B, C, D, E Foldable in pairs against the respective preceding mast arm in an essentially parallel alignment, further mast arms 2, 3, 4 and 5 lying in the driving position under the mast arm 1, and connected to one another by tubular rotary couplings which are axially parallel to the articulated joints and extend along the individual mast arms Pipe sections of a conveyor pipe which can be loaded with concrete and which leads to an end hose which is articulated at the free end of the mast arm 5, the mast arms 1, 2 and 3 following in opposite directions at their articulated joints B and C, which have a swivel range of approximately 180 ° Type of a Z-fold can be folded against each other.
- 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 with advantage both in low construction sites and in building construction.
- the Multi-Z folding also ensures a quick operational readiness after only a short lifting of the partially unfolded Arm packages and a high degree of flexibility, in particular when concreting hard-to-reach places, dead spaces being largely avoided both in the case of high conveyance close to the vehicle and when concreting in low rooms.
- the articulated joints C and E close to 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. However, 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 of developing a concrete placing boom of the type specified at the outset, which can be used both in ground-level, lower rooms by overcoming obstacles and in higher floors for concreting with parallel hose routing and the lowest possible unfolding height.
- the mast arms 3, 4 and 5 and the associated pipe sections on their joints D and E each fold in the same direction as the mast arms 2 and 3 in the area of the joint C in the manner of a roll fold ⁇ are bar.
- the mast arm 2 in addition to a guiding function in the ground-level concrete, also has an unloading function which allows obstacles to be overcome in the ground-level area and over several floors, while the connecting 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 directly up to the obstacle to be overcome.
- the articulated joint D and / or the articulated joint E has a pivoting angle of approximately 270 °.
- FIG. 1 shows a side view of a truck-mounted concrete pump with a five-armed concrete placing boom in the folded-up driving state
- End hose manipulator placed on the concrete placing boom for filling tunnel formwork in a side view, an end view and an enlarged side view of the end hose manipulator.
- 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 placing boom 20 rotatable on the pivot bracket 16 about a vertical axis 18 through 360 °, one over a Material feed container 22 which can be acted upon with concrete, hydraulically driven concrete pump 24 and a delivery line 28 connected to the concrete pump 24 via a pipe switch 26.
- the distributor mast 20 has five mast arms 1, 2, 3, 4 and 5, which are connected to one another at the swivel joint A with the pivot bracket 16 and at the articulated joints B, C, D and E.
- the mast arms 1 to 5 are folded in and out hydraulically around the joints A to E by means of double-acting hydraulic cylinders 30 which, with their free cylinder-side and rod-side ends, on brackets or folding brackets of the mast arms 1 to 5 and the pivot bearing ⁇ blocks 16 are articulated.
- 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 In the driving position shown in FIG. 1, the mast arms are folded against one another in an essentially parallel alignment, the mast arms 2, 3, 4 and 5 coming to rest under the base arm 1.
- the mast arms 1, 2 and 3 on their articulated joints B and C are folded in opposite directions in the manner of a Z-fold, while the mast arms 3, 4 and 5 on their articulated joints D and E are each in the same direction as the masters. arms 2 and 3 are folded against each other like a roll fold.
- FIG. 2a and b illustrate the method of working when concreting the floor at ground level in lower rooms, in particular in a factory hall 32.
- the mast arms 2 to 5 are first pivoted with the base arm 1 slightly raised in the downward folded 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 to it 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 the operator moves towards emphasizing places is directed.
- the end hose can be displaced along a working line L parallel to the floor up to directly in front of the driver's cab 14.
- the unfolding height H is only slightly higher than the working line L traversed by the free end of the end arm 5. From the end position of the end hose 36 near the driver's cab shown in FIG. 2b, it is then only necessary some one fold movements to bring the mast arms 2 to 5 into their folded position shown on the right in FIG. 2a.
- the described truck-mounted concrete pump 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 pipe 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 essentially axially parallel hydraulic cylinder 48 is pivotally mounted.
- the flexible end hose 36 is connected, which in its end third has a sleeve 50 formed as a clamp, which is provided with lateral pivot bearings 52 on 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 relative to the load arm 54.
- the pivot lever 56 can be pivoted in an angular range of approximately 60 °.
- a housing 66 for accommodating a hydraulic motor 68 is arranged on the pipe section 46, 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 in any rotational position relative to the pipe section 46.
- the rotation and tilting movement of the end hose 46 is carried out 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 nozzles or windows 76 of a tunnel formwork 78.
- the invention relates to a five-armed concrete placing boom 20 arranged on a vehicle, its masts 1, 2 and 3 at its articulated joints B and C, which have a pivoting range of approximately 180 °, in opposite directions in the manner of a Z. - Foldable against each other.
- the mast arms 3, 4 and 5 have joints D and E each having the same swivel range of approximately 270 ° to the masts 2 and 3 are foldable against each other in the area of their articulated joint C in the manner of a roll fold.
