Definitions

  • the invention relates to a floor support device for a vehicle according to the preamble of claim 1.
  • the prior art also includes extendable support devices, the support arms of which are pivotably articulated on the vehicle frame, the pivot angle being variable by means of a hydraulic cylinder unit, so that variable support widths can be achieved by extending the ground contact bars by means of further hydraulic cylinder units.
  • the disadvantage here is the relatively large structural complexity and space requirements, in particular the comparatively large number of interacting support beams, two hydraulic actuating cylinders being required per support (DE-OS 26 09 711; US Pat. No. 3,279,622).
  • the object of the invention is to provide a floor support device for a vehicle of the type mentioned, which is simple in construction and nevertheless allows different support widths, with little conversion effort and without welding work and paint damage.
  • the invention therefore provides a support spar on the vehicle which is not designed with a constant cross-section in the longitudinal direction as before, but with a conical widening in the direction of the exit side.
  • This increase in cross-section makes it possible to produce a small and a large support width in a relatively simple manner, with the aid of a guide wedge on the inside of the support spar, which for a small support width on the inner upper side of the support spar and for a large support width on the inner underside of the support spar, in particular by screwing is arranged.
  • the wedge angle corresponds to the angle of the conical extension of the support bar.
  • the bolt for the hydraulic cylinder unit for extending and retracting the floor contact bar is hooked into the associated upper mounting hole of the support bar.
  • the ground contact spar expediently has a conical taper on the upper side of its entry side, the slope of the conical taper corresponding to the slope of the conical extension of the support bar.
  • a conical taper of the ground-contact bar is assigned a longitudinal section of the support bar that has a constant cross section.
  • another guide Wedge can be arranged at least in a lower inner support beam position.
  • the upper side of the support bar is expediently straight in the longitudinal direction, and the support bar is therefore of simple construction.
  • the structure is further simplified by support bars and floor contact bars, which are designed as square tubes.
  • At least one additional sliding block is preferably arranged in the support beam on the extension side, to which a second sliding block is expediently assigned on the underside of the ground contact beam on the entry side.
  • the first and second sliding blocks not only reduce the sliding friction of the device during operation, but also limit the maximum extension stroke of the device, namely when the first and second sliding blocks come into axial engagement.
  • a hydraulic cylinder unit inside the spar is provided for each side outrigger.
  • the actuating cylinders required in the prior art for adjusting the pivoting angle of the support bars attached to the vehicle frame are omitted in the invention.
  • the advantages of the convertible angled support clearly relate to the same components of the supports, and the low stocking of finished vehicles.
  • simple conversion measures individual vehicle types are installed, which take into account different demands of the domestic and foreign market.
  • the user has the option of converting an already delivered vehicle to the other support width using simple means.
  • the support width can be adjusted or reset for a new vehicle with a changed frame height.
  • the different outrigger widths make it possible to sell vehicles from home to exporting countries because larger outreach values can also be assigned to the larger outrigger.
  • the components "support bar, floor contact bar, hydraulic cylinder unit" remain essentially the same. Only the support plates and the turn signal bracket need to be replaced.
  • the invention is primarily suitable for aerial rescue vehicles, work and rescue equipment, telescopic or articulated mast platforms; the generic concept of the invention is to be understood correspondingly comprehensively.
  • a floor support device (1) for an emergency vehicle with an extendable aerial ladder in the rear area of the vehicle on the vehicle frame (16) has right and left attached downwardly directed support arms (2).
  • Each support arm (2) comprises an inclined outer support beam (3) fastened to the vehicle frame (16) and an inner telescopically extendable ground contact beam (4) guided in the support beam (3).
  • the support bar (3) and the ground contact bar (4) are connected to each other by a hydraulic cylinder unit (15) on the inside of the bar and can be extended or retracted by switching a hydraulic force. Both spars (3, 4) are designed as square tubes.
  • the ground contact bar (4) has a hinged support plate (17) on the exit side, which comes into contact with the actual floor if necessary.
  • the support bar (3) is firmly connected to the vehicle frame (16) at a predetermined oblique angle. In a special cross-sectional configuration, it has a conical extension (8) in the longitudinal direction, which accounts for approximately three quarters of the total length of the support strut on the exit side.
  • the remaining longitudinal section (1) of the support bar (3) has a constant cross section. In this end area there are two differently arranged receiving bores (13, 14) for articulating the associated piston rod of the hydraulic cylinder unit (15), as will be discussed below.
  • the conical extension (8) is realized on the underside of the support bar (3).
  • the upper longitudinal side (10) of the support bar (3) is therefore straight.
  • a floor contact bar (4) is guided, which has a conical taper (7) on the entry side.
  • the slope of the conical taper (7) corresponds to the slope of the conical extension (8) of the support bar (3).
  • the floor contact bar (4) is guided in the outer support bar (3) in its one steep guide direction (A), the longitudinal axis (18) of the floor contact bar (4) having a large angle ( ⁇ ) to the horizontal.
  • a guide wedge (5) in the conical extension (8) on the inner upper extension side of the support bar (3) which is screwed (6) to the upper one Long side (10) of the support bar (3) is detachable, but is firmly connected.
  • the angle of the guide wedge (5) also corresponds to the aforementioned conicity (7 or 8).
  • a further guide wedge (9) is provided on the inner lower entry side of the support beam (3), which is also adapted to the aforementioned conicity. In this way, an exact, essentially play-free, longitudinal guidance of the ground contact bar (4) in the support bar (3) surrounding it is ensured according to FIG. 1.
  • the support bar (3) On the extension side, the support bar (3) has a lower first sliding block (11) and a further first sliding block (11) on the upper side in connection with the guide wedge (5).
  • a second sliding block (12) is fastened on the underside of the ground contact bar (4).
  • the floor 1 is articulated via the hydraulic cylinder unit (15) to the upper receiving bore (13), which is located on the longitudinal central axis (18) of the ground contact bar (4).
  • the guide wedge (5) is located on the other (lower) inside of the support spar (3) in the region of the conical extension (8) with respect to the embodiment according to FIG. 1.
  • the longitudinal central axis (18) of the ground contact bar (4) according to FIG. 2 therefore takes up an angle ( ⁇ ) to the horizontal that is smaller than the angle ( ⁇ ) according to FIG. 1.
  • the hydraulic cylinder unit (15) is on the lower receiving bore (14) of the support bar (3) is articulated, the center of which runs through the longitudinal central axis (18), which is now arranged incorrectly.
  • the further guide wedge (9) of the embodiment variant according to FIG. 1 is removed in the longitudinal section (1). An arrangement of the guide wedge (9) on the top is unnecessary. It is sufficient if the ground contact bar (4) is supported as shown in FIG. 2.
  • FIG. 3 the aforementioned embodiment variants according to FIGS. 1 and 2 are shown in a superimposition, wherein the floor contact bars (4) are each extended to their different support widths (C and D). Obviously there is a larger support width (C) in the embodiment variant of the floor support device (1) according to FIG. 2 in comparison to the embodiment variant according to FIG. 1.
  • the one variant can easily be converted into the other variant by appropriate mounting of the guide wedges (5, 9) are, whereby the hydraulic cylinder unit (15) is to be mounted in the associated mounting hole (13 or 14).
