This application is a national stage of PCT/EP2005/000295 filed Jan. 14, 2005 and based upon DE 10 200 007 509.3 filed Feb. 13, 2004 under the International Convention.
Beginning therewith, it is the task of the invention to modularly design the boom support unit in such a manner that it becomes capable of providing a supplemental function within the mobile concrete pump. The solution of this task is proposed in the combination of characteristics set forth. Advantageous embodiments and further developments of the invention can be seen from the dependent claims.
A preferred embodiment of the invention envisions that the housing part includes a first and a second frame part, that the first frame part is mounted fixed to the vehicle chassis and carries the control elements in its interior, and that the second frame part can be removed from the first frame part and carries at least one support block on its upper side the. Preferably the frame parts are respectively in the shape of an “L” and can be engaged with each other to form a housing box having a rectangular profile. Therein the at least one support block is advantageously provided on the outside of the upper (horizontal) L-shank of the second frame part. This L-shank can exhibit for this purpose a grid or pattern of holes for securing support blocks various sizes or different design. Further, the second frame part can advantageously exhibit on its side (vertical) L-shank a holder device for a water hose, which can be connected to a water tank equipped with a water pump for cleaning up purposes. Besides this, the second frame part can advantageously exhibit on its side (vertical) L-shank an access opening with a lockable lid.
One preferred embodiment of the invention envisions that at least parts of the housing part and/or the support block of the boom support unit are made of light construction materials. The light construction materials are preferably fiber reinforced plastic, in particular CFRP (carbon fiber reinforced plastic) or GFRP (glass fiber reinforced plastic). Alternatively thereto, the light construction material can be a metal foam, preferably also with aluminum or titanium components. The light construction materials of the housing part and/or the support block preferably carry a friction resistant and/or hard coating, which can be selected for example from the material group chrome, aluminum, silicon carbide or ceramic.
In the following the invention will be described in greater detail on the basis of the illustrative embodiment represented in schematic manner in the figure. There is shown
FIG. 1: A side view of a mobile concrete pump with distribution boom in transport position resting upon the boom support unit;
FIG. 2: A rear view of the boom support unit with distribution, lying thereupon;
FIG. 3: An illustrative exploded representation of the boom support unit without lid and side wall.
The mobile concrete pump shown in the figures includes a frame 10 connected rigidly to a truck chassis. Two front and two rear telescopic and/or pivotable support outriggers 14, 16 are provided on the frame 10 with which the vehicle chassis 12 is supportable upon a substrate 20 with lifting of the wheels 18. The mobile concrete pump further includes a two-cylinder thick matter pump 22, which can be supplied with concrete via a material supply container 24 at the rearward part of the chassis. The two-cylinder thick matter pump 22 communicates on the pressure side with a concrete conveying conduit 26, which is guided along a distribution boom 28 in the form of an articulated boom and communicates at its terminal end with a not shown end-hose. The distribution boom 28 is mounted rotatably about a vertical axis 34 on a vehicle chassis fixed rotation block 32. The articulated boom is comprised of multiple boom arms 38 pivotable relative to each other about parallel articulation axis 36, which in the working condition are so adjustable relative to each other, that they are adapted to bridge over the distance to a location to be provided with concrete. In the folded together transport position the boom arms 38 form an arm packet directed rearwards on the chassis, resting on a vehicle chassis fixed boom support unit 40 (see FIGS. 1 and 2). The boom support unit 40 is located, in the illustrated embodiment, on the rearward end of the vehicle chassis 12 between the material supply container 24 and a water tank 42. In the water tank 42 water is transported along to the work site, which is needed at the end of the pumping process for cleaning of the concrete pump.
In the housing part 44, in the illustrative embodiment, components of the hydraulic pump control 56 including pressure reservoir 58 are provided. Further, actuating lever 60 is accessible there via the opening 46 which enables an emergency operation by hand. The first frame part 52 is fastened with threaded fasteners onto the frame by its lower L-shank 62. The essential parts of the pump control 56 are fixed to the first frame part 52. The second frame part 54 completes the housing part and closes it off along its two open sides and is fastened with threaded fasteners to the first frame part forming a stable frame construction. The support blocks 50 are screwed onto the upper L-shank 64 of the second frame part. Keeping the same design of the second frame part 54, various types of support blocks 50 can be attached depending upon boom type. For this purpose various hole patterns can be provided on the upper L-shank 64 of the second frame part 54, which are intended for various support blocks 50. The open sides of the housing are closed with suitable shields or covers 68. In the lower part there is further provided a rubber skirt 70, which forms a spray shield relative to the adjacent material supply container 24.
