Definitions

  • the invention relates to a Obergurtquerexcellent for Kranteleskopteil.
  • it relates to a Obergurtquerexcellent for telescopic parts of a vehicle crane.
  • Telescopic crane jibs are exposed during operation to a load which results in a tension in the upper belt, that is to say in the upper half of the telescopic part cross-section.
  • horizontal bending and torsion can occur due to lateral forces (wind) and off-center loads.
  • the cross-section should be able to absorb the resulting stresses as well as possible due to its shape, and both are the case with the embodiment according to the invention.
  • a number of bends are created on the one hand, which act as idealized Beulsteifen. This is of great advantage for rocker tip operation but also in prestressed and / or guyed boom systems, and the need to provide separate buckling stiffeners is minimized or eliminated altogether.
  • the provision of the number and shape of cross-sectional elements according to the invention has the effect that bends are present in the lateral cross-sectional parts, so that the lateral single tuberosities are more limited and the total field of heel stiffened, unlike, for example, the relatively large or long single tuber surfaces that z. B. according to the DE 200 04 016 U1 to be provided.
  • the lateral Beulschreib is thus increased.
  • the outwardly curved cross-sectional elements can be designed so that they can be introduced with a single tool and in a crosstie, resulting in the entire upper flange (upper shell) a total of four bends or curves. This results in an easier manufacturability than in the provision of extended and adjoining curved elements, as for example from the EP 1 321 425 A1 is known.
  • the flat (or straight-sided or rectilinear) cross-section elements offer the possibility of positioning the edging tool very precisely, thus ensuring high process reliability.
  • the present invention provides an optimal synthesis between manufacturing and strength optimization.
  • the third flat cross-sectional element extends parallel to the vertical longitudinal plane of the Kranteleskopteils and forms the lower end of the upper flange.
  • the cross section runs through this arrangement at its lower end straight back down and can thus well merge into a corresponding extending lower chord, which also creates an optimized introduction of force at this junction.
  • the upper belt cross-section forms substantially the entire upper half of the telescopic part cross-section, i. the lower end is located substantially at the height of the vertical cross-section center.
  • At least one, in particular all transitions between the flat cross-sectional elements and the outwardly curved cross-sectional elements extends tangentially. This avoids voltage spikes at the junctions.
  • the length ratios and the curvature ratios can also be reversed depending on the individual case or equal lengths and curvatures can be provided for the elements.
  • the second flat cross-sectional element is not longer than the third flat cross-sectional element.
  • the cross-sectional elements can be arranged exactly in the above-mentioned order from the central upper element to the outside. Furthermore, it is advantageous according to the invention if the cross-sectional elements are arranged so that flat and curved elements alternate.
  • “Curvature” or “bend” here mean gradual, curved or curved transitions in contrast to creases or angular transitions (with and without welds).
  • the figure shows a cross section of a Kranteleskopteils, in particular for a vehicle crane.
  • a telescopic boom usually consists of a base part and a plurality of telescopic shots, and according to the invention the base part and / or the telescopic shots can have the cross-sectional shape according to the invention.
  • the telescopic part cross-section is generally designated by the reference numeral 10 and it has a top flange 11 (upper shell) and a Lower flange 12 (lower shell), which are connected to one another at the point marked 13, in particular welded.
  • the upper flange 11 has according to the invention on five flat cross-sectional elements and four outwardly curved cross-sectional elements. Also according to the invention, the flat elements alternate with the outward elements.
  • the upper flange 11 has a flat element 1, which in the present case extends on both sides symmetrically to the vertical longitudinal plane 14 and overall forms the longest flat cross-sectional element.
  • the curved cross-sectional elements 2 and 4 are preferably designed so that they can be introduced with a tool and in each case a Kantgang.
  • the top flange 11 then receives a total of four edgings (bends or bends). An accurate positioning of the Kant tool is possible during manufacture by the straight or flat sections 1, 3 and 5, which increases the process reliability.
  • the radii of the curved cross-sectional elements 2 and 4 are preferably designed so that they can be introduced with a tool and each with a Kantgang. Thus, a tool change during the production of Obergurtschalen is unnecessary.
  • the radii are chosen in such a way that the different material properties, sheet thicknesses and bevel angles are taken into account (therefore other curvature ratios than stated above are possible, also reversed ones).
  • the Transitions are made as far as possible tangential to avoid voltage spikes.
  • the curved sections or the bends in the overall cross-section act as Beulsteifen, the straight sections facilitate the production and overall, therefore, according to the invention an optimized between these parameters cross-sectional shape is provided.
