Definitions

  • the invention relates to a truck mixer with a mixing drum and a control mixer arranged on the truck for operating the mixing drum, wherein at least one roof is mounted on the truck mixer to protect a person staying at the control station from above coming environmental influences.
  • the control station Since the control station is located on the outside of the vehicle, the operator of the truck mixer stands during this time and thus a large part of his working time unprotected outdoors, it is therefore exposed to the prevailing weather conditions unprotected. Regardless of this, water (rain, mist from driving or cleaning) from the components of the truck mixer above the operating console can also drip onto the operator.
  • the aim of the present invention is therefore to provide the operator of a truck mixer better protection against external environmental influences.
  • a truck mixer which provides an outside of the vehicle arranged control station for controlling the mixing drum.
  • a roof is also mounted on the truck to the truck. This roof provides the operator with protection from above-mentioned environmental influences as well as from any kind of falling parts.
  • Essential to the invention is that the roof surface is variable in size.
  • the version with variable roof area has the advantage that the maximum available roof area can be made much larger in order to provide adequate protection.
  • the roof area can be reduced to reduce the influence on the vehicle dimension.
  • the reduced roof area has no effect on the vehicle dimension of the truck mixer, ie the roof surface does not protrude laterally beyond other components of the vehicle.
  • the roof surface would protrude beyond the steel structure of the truck mixer to provide sufficient protection for the operator and thus increase the risk of collision when driving on construction sites and narrow passages.
  • the rigid roof structure would intervene in the working space of the truck mixer, for example, impairing the unloading process of the mixing drum contents into a comparatively large crane bucket.
  • the underrun protection would have to be mounted farther back, which would make it more difficult to operate the truck mixer (for example when approaching concrete pumps) or increase the distance of the operator to the controls.
  • the design of the roof with a flexible roof surface variation mechanism can counteract the aforementioned problems, as the roof area can be reduced if necessary, e.g. for transport purposes of the truck mixer or for certain work assignments. If, on the other hand, sufficient space is available, the roof area can be increased to such an extent that the operator standing underneath is provided with sufficient protection against external influences.
  • the roof surface can be increased or reduced in the horizontal direction, in particular parallel to the vehicle longitudinal axis.
  • the roof structure may be formed in several parts from a plurality of roof elements, which are movably mounted, preferably displaceable to each other.
  • at least one fixedly mounted on the vehicle roof element is provided on which at least one further roof element is movably mounted.
  • the resulting roof surface can be variably adjusted.
  • Particularly suitable is a telescopic arrangement of at least two roof elements.
  • an outer roof element can be fixedly mounted on the vehicle structure, while at least one further roof element, preferably a smaller surface area roof element, can be pushed or telescoped onto or under or into the fixedly mounted roof element.
  • At least one roof element on guide elements for leading receiving at least a second roof element can be provided with one or more grid holes to lock the roof elements against each other. Corresponding locking bolt of the other roof element will be inserted into the matching grid holes. The number of grid holes thus determines the number of different telescoping positions or adjustable roof sizes.
  • an inclined arrangement of the roof surface with respect to the horizontal proves to be useful to provide sufficient water drainage.
  • the direction of drainage can be determined via the roof pitch.
  • a water drain to the vehicle side is achieved by the corresponding inclined roof surface.
  • the inclination of the roof surface is achieved either by the solid shape of the roof elements or can be influenced by an adjustable mechanism.
  • a construction of the roof turns out to be at least one roof element, which is characterized by a curved cross-sectional profile. Due to the curved cross-sectional profile, a sufficient inclination relative to the horizontal is already achieved.
  • the version with adjustable mechanism has the advantage that the inclination can be changed depending on the position of the sun and the roof thus offers the operator a variable sun protection.
  • the roof can optionally be provided with one or more side walls, in addition to the roof to provide protection against lateral influences. It is conceivable that these side walls are at least partially releasably connected to the roof and are therefore attached only when needed. It is also conceivable a hinged or telescopic or any type of adjustable arrangement of the side walls on the roof to unfold them when needed, baggage or to provide by any other form of movement and to save space in space or for transport purposes to save space on the roof.
  • a size or surface variable configuration of the one or more side walls can be adjusted in variable length in the vertical direction.
  • the roof of the invention is preferably mounted on the rear of the truck mixer, ideally below a pedestal of the truck mixer for maintenance and cleaning of the mixing drum.
  • a height-adjustable arrangement of the roof on the truck mixer in order to adjust this depending on the height of the respective operator.
  • the arrangement of the roof on the truck mixer can for example take place via at least one carrier, via which the roof is suspended from the overlying pedestal.
  • Suitable here is a composition of at least two carriers that allow a V-shaped suspension on the overhead pedestal.
  • the roof construction is preferably detachably connected to the carriers in order to realize the height adjustment by flexible mounting on the carrier or carriers.
  • Conceivable is a screw, wherein the or provide the carrier several staggered holes for the height-adjustable installation.
  • the roof or at least one roof element may be connected to a provided vertical ladder of the truck mixer. Again, the possibility of height adjustment can be realized in a similar manner to the carriers.
  • FIG. 1 showed a sketched side view of the truck mixer according to the invention.
  • the truck mixer comprises a chassis 30 with a multi-axle chassis and a driver's cab 31 provided on the vehicle front for locomotion of the truck mixer. Behind the cab 31 is the rotatably mounted mixing drum 32.
  • an operating stand 33 is provided which comprises the control levers and display elements for the control of the mixing drum 32.
  • the operator can control the direction of rotation and rotational speed of the mixing drum 32 from there.
  • a ladder 8 is provided, via which the operator can ascend to the upper portion of the mixing drum 32.
  • the operator can reach the pedestal 37, which provides a standing platform for the maintenance and cleaning of the drum top.
  • the pedestal 37 Since the operating stand 33 is arranged below the pedestal 37 on the vehicle, the pedestal 37 has hitherto served as a temporary weather protection for a person standing on the control stand 33. This protection has proven in practice to be insufficient, so that the truck mixer according to the invention is equipped with an additional roof 1, 2, the operator standing on the control stand 33 sufficient protection against external environmental influences as well as on the vehicle itself dripping water or other Offers objects.
  • FIG. 2a A representation of the roof according to the invention shows FIG. 2a , This figure discloses the roof in a side view according to FIG. 1 , Visible is the riser 8, to which a part of a first fixedly mounted on the vehicle roof element 2 is added.
  • This roof element 2 may be a matching sheet metal construct, with a curved cross-sectional profile according to the FIG. 4 showing a view of the rear of the vehicle.
  • the curvature or inclination of the roof surface extends in the direction of the vertical ladder, so that water dripping onto the roof runs off in the direction of the vertical ladder 8 on the vehicle side.
  • a top view of the sheet 2 is in the FIG. 6 shown.
  • a profile representation results from the FIG. 4 showing the curved roof profile in the direction of the vertical ladder 8.
  • the vehicle center axis facing the roof edge of the fixed roof element 2 is suspended by means of the two carriers 5, 6 located on the above the roof pedestal 37 of the truck mixer. Both carriers 5, 6 form a kind of V-suspension.
  • the roof surface of the roof element 2 already shown already offers protection to the person standing on the control stand 31, but does not protrude beyond the vehicle dimension of the rear region. If necessary, the roof area can be significantly increased.
  • at least one second roof element 1 is mounted telescopically on the first roof element 2, more precisely on the underside of the roof element 2. This can be seen in FIG. 2b which reveals a view of the underside of the roof construction.
  • the shape of the roof elements is approximately equal, in particular, both elements 1, 2, the curved cross-sectional profile, but the second roof element 1 is designed shorter.
  • FIG. 3a a side view according to FIG. 2a represents and FIG. 3b take a look at the back of the illustration according to FIG. 3a allowed.
  • the roof area can be almost doubled in the horizontal direction and provides the operator standing underneath much more protection than in the telescoping state.
  • the telescoping is realized via a telescopic rail 7 of the first roof element 2, in which the movable roof element 1 slides in the horizontal direction parallel to the vehicle longitudinal axis.
  • the guide rail also provides a plurality of grid holes 22 into which a pin of the roof element 1 can be stuck for mutual locking.
  • the number of grid holes 22 determines the possible telescoping positions of the roof elements 1, 2.
  • the roof elements 1, 2 are fixed in the respective Teleskopierposition.
  • the supplementary bolt connection 18 ( Fig. 5a ) in the region of the outer roof edge of the roof element 2 by means of which the roof elements 1, 2 additionally secured in the fully einteleskop investigating position.
  • both bolt connections 10, 18 are equipped with a suitable pull knob 13 to solve the lock tool-free.
  • FIG. 5c The mounting of the roof element 2 to the carriers 5, 6 takes place by screw, as described in detail of FIG. 5c can be seen. Also visible in the vertical direction are a plurality of mutually offset boreholes 14 (FIG. Fig. 2a ) in the carriers 5, 6 in order to screw the roof elements at different heights to the carriers 5, 6 can.
  • Suitable side walls can be realized by tarpaulins, curtains, telescopic elements or similar sliding doors.
  • the length of the vertical guards can be made variable.
  • the predefined inclination of the roof elements 1, 2 not only provides sufficient water drainage, but the curvature to the outside of the truck mixer also provides for diagonal sunshine or heavy rain with heavy wind for additional protection.
