    Background of the invention
    Developments in concrete construction methods include the mechanized transfer of concrete from a source, such as a ready-mix concrete truck or the like, to a relatively remote and/or confined location on the building or construction site.
    This permits the positioning of the heavy-duty concrete trucks at a convenient location in spaced relation to the application points, and avoids the difficult and time-consuming manual transfer of the concrete from the truck to the application point. However, even with motorized wheelbarrows and the like, the transfer requires a suitable path as well as a significant amount of time to effectively distribute the concrete. This not only results in a relatively high labor cost, but also results in a significant delivery time for the ready-mix truck or the like.
    Other systems have employed a mobile concrete pump unit with a detachable conduit hose of a flexible material, which is manually mounted along a predetermined path or the like. The flexible hose is heavy and requires a plurality of workers to manipulate the hose. Furthermore, it is extremely difficult to evenly distribute the discharging material, and additional personnel is required to more evenly spread the concrete material.
    Summary of the invention
    It is an object of the present invention to overcome the above mentioned problems.
    One aspect relates to a mobile distributor apparatus for distributing thick matter, in particular for distributing uncured concrete, comprising: - a frame supported for movement over a surface by wheels or belts; - a steering mechanism associated with the wheels or belts; - a rotatable drum with a hose wound thereon in a plurality of side-by-side convolutions in at least one layer; - a hose-guide reciprocated parallel to the axis of rotation of the rotatable drum as said drum is rotated; and - a distributor arm connected to the outlet of the hose; wherein the inlet of the hose comprises means for releasably fastening to the outlet of a thick matter pump unit.
    Another aspect relates to a mobile distributor apparatus for distributing thick matter, in particular for distributing uncured concrete, comprising: - a rotatable drum with a hose wound thereon in a plurality of side-by-side convolutions in at least one layer; - a hose-guide reciprocated parallel to the axis of rotation of the rotatable drum as said drum is rotated; and - a distributor arm connected to the outlet of the hose; wherein the inlet of the hose comprises means for releasably fastening to the outlet of a thick matter pump unit.
    The present invention relates to a mobile distributor apparatus comprising a frame, a steering mechanism, a rotatable drum with a hose wound thereon, a hose-guide, and a distributor arm.
    The frame is supported for movement over a surface by wheels or belts, and the steering mechanism is associated therewith.
    The hose is wound on the rotatable drum in a plurality of side-by-side convolutions in at least one layer. The hose and the rotatable drum makes it possible for the mobile distributor apparatus to move away from the thick matter pump unit, such as a heavy-duty concrete truck, from which it is coupled when active. Hence, the hose leaves the rotatable drum as the mobile distributor apparatus moves forward, and is thereby placed behind the mobile distributor apparatus. When the mobile distributor apparatus moves backward, the hose will be rewound by the rotatable drum. In one or more embodiments, the rotatable drum is configured to unwind the hose as the mobile distributor apparatus moves forward. In one or more embodiments, the rotatable drum is configured to rewind the hose as the mobile distributor apparatus moves backward.
    In one or more embodiments, the rotatable drum is adapted to unwind and rewind the hose with a speed adjusted to the speed of the mobile distributor apparatus.
    In one or more embodiments, the rotatable drum is coupled to the wheels by a speed reduction gear unit. This is to overcome the differences in diameter of the wheels and the drum, whereby the rotatable drum can unwind and rewind the hose with a speed adjusted to the speed of the mobile distributor apparatus.
    The hose-guide is reciprocated parallel to the axis of rotation of the rotatable drum as said drum is rotated. Thereby, the hose is positioned in the right position on the drum during unwinding and rewinding.
    In one or more embodiments, the frame is supported for movement over a surface by wheels, and wherein the rotatable drum is coupled to the wheels by a speed reduction gear unit. This is to overcome the differences in diameter of the wheels and the drum.
    In one or more embodiments, the distributor arm is configured for up/down and sideways movement. This configuration makes it easier to distribute the thick matter within a confined space.
    In one or more embodiments, the mobile distributor apparatus does not comprise a thick matter pump unit. The main purpose of the mobile distributor apparatus is not to pump the thick matter, but to reach a position within a confined space, and to provide connection to a thick matter pump unit, such as a heavy-duty concrete truck, such that the thick matter can be transported thereto.
    In one or more embodiments, the mobile distributor apparatus further comprises a motor unit (e.g. a hybrid motor unit) operatively connected to the wheels or belts.
    In one or more embodiments, the mobile distributor apparatus further comprises an electric motor unit and a combustion motor unit, both operatively connected to the wheels or belts. This is an advantage when the mobile distributor apparatus is entering a confined space, where there is little air exchange. The mobile distributor apparatus can then run on battery rather than fuel to avoid using the oxygen in the air and expelling toxic gasses thereto.
    In one or more embodiments, the steering mechanism and/or motor unit and/or distributor arm are responsive to remotely-controlled electrical signals.
    Preferably, the hose is adapted for the working pressure of the thick matter pump unit, such as a heavy-duty concrete truck.
    In one or more embodiments, the hose is adapted for a working pressure of at least 5 bar, such as at least 10 bar, such as at least 15 bar, such as at least 20 bar, such as at least 25 bar, such as at least 30 bar, such as at least 35 bar, at least 30 bar, such as at least 35 bar, such as at least 40 bar, such as at least 45 bar, such as at least 50 bar, such as at least 55 bar, such as at least 60 bar, such as at least 65 bar, such as at least 70 bar, such as at least 75 bar, such as at least 80 bar, preferably at least 85 bar, such as at least 90 bar, such as at least 100 bar, such as at least 120 bar, such as at least 140 bar, such as at least 160 bar, such as at least 180 bar, such as at least 200 bar, which is the operating pressure of a thick matter pump unit, such as a heavy-duty concrete truck.
    In one or more embodiments, the mobile distributor apparatus further comprises a tensioning apparatus engaging the outer surface of the hose at a position adjacent the hose-guide; wherein the tensioning apparatus comprises driving means therefore, and operable on the hose as the drum is rotating, thereby to maintain said hose in tension and thereby to prevent the convolutions on the drum from becoming loose on said drum.
    It should be noted that embodiments and features described in the context of one of the aspects of the present invention also apply to the other aspects of the invention.

    Detailed description of the invention
    Referring to Figure 1, the general scheme of the invention is shown in perspective view. Figure 1 shows a mobile distributor apparatus 100 comprising a frame 200, a steering mechanism (not shown), a rotatable drum 300 with a hose 400 wound thereon, a hose-guide 500, and a distributor arm 600.
    The frame 200 is supported for movement over a surface by wheels, and the steering mechanism (not shown) is associated therewith.
    The hose 400 is wound on the rotatable drum 300 in a plurality of side-by-side convolutions in one layer. The hose 400 and the rotatable drum 300 makes it possible for the mobile distributor apparatus 100 to move away from a thick matter pump unit, such as a heavy-duty concrete truck, from which it is coupled when active (not shown). Hence, the hose 400 leaves the rotatable drum 300 as the mobile distributor apparatus 100 moves forward, and is thereby placed/released behind the mobile distributor apparatus. When the mobile distributor apparatus moves backward, the hose will be rewound by the rotatable drum.
    The hose-guide 500 is reciprocated parallel to the axis of rotation of the rotatable drum 300 as said drum is rotated. Thereby, the hose 400 is positioned in the right position on the drum 300 during unwinding and rewinding. Figure 3 shows a rear view of the mobile distributor apparatus 100 with the hose-guide 500 positioned in the rear end of said apparatus.
    The distributor arm 600 is configured for up/down and sideways movement. This configuration makes it easier to distribute the thick matter within a confined space.
    The mobile distributor apparatus is shown with a motor unit 700 operatively connected to the wheels (Figures 2 and 3).
