Definitions

  • the invention relates to an underframe for a platform trolley.
  • Underframes for platform trucks, in particular container carriers, are known from the prior art, which include a longitudinal beam which is arranged between two head pieces, each with a buffer chest for the arrangement of one or more buffers.
  • the longitudinal beam defines a loading area for the arrangement of containers and extends along a central longitudinal axis between the two head pieces.
  • the EP 2 837 542 A1 Such a known underframe for a container wagon, which is composed of a large number of individual support elements consisting of steel profiles.
  • This known underframe comprises two outer longitudinal members which run parallel to one another on the outside of the underframe and are connected to one another at the head pieces via transverse buffer members. A discharge opening is formed between the outer side members.
  • the two outer side members are reinforced by transverse struts.
  • the outer side members are usually formed from welded I-beams or box profiles
  • underframes are complex and expensive to manufacture due to the large number of longitudinal weld seams.
  • the strength of the base material used cannot be exploited, since the strength is reduced by the weld seams.
  • no higher-strength steels have been used as a material so far.
  • the object of the present invention is thus, inter alia, to create an underframe for a platform trolley that is simple to manufacture, has as few individual elements as possible, and yet ensures greater strength.
  • a strength of category FI instead of FII according to EN 12663-2 should be guaranteed.
  • Weld seams should be avoided as far as possible, and an optimal flow of forces should be made possible with as few connection elements as possible.
  • the weight of the base should be reduced if possible.
  • the longitudinal member comprises an upper chord and a lower chord, which are arranged essentially one above the other and are connected to one another and to the head pieces at their ends via longitudinal webs.
  • the upper belt is in one piece. It can also be provided that the lower chord is also in one piece.
  • the longitudinal webs arranged on the head pieces are each in one piece. This significantly reduces the number of elements required, so that in the ideal case, in addition to the upper and lower chords, only two longitudinal webs each are required to connect to one head piece.
  • the invention can particularly stand out when using high-strength steels from voestalpine, in particular the alform® material family with a minimum yield strength of over 550 MPa up to 700 MPa, in particular in the upper chord, the lower chord and the entire head piece.
  • the width of the longitudinal member transversely to the central longitudinal axis of the longitudinal member is smaller than the width of the head pieces transversely to the central longitudinal axis.
  • the width of the longitudinal member transversely to the central longitudinal axis is approximately 20% to approximately 70%, preferably approximately 40%, of the width of the head piece transversely to the central longitudinal axis. This results in further material savings while maintaining the same strength.
  • the upper chord and the lower chord are essentially structurally identical. This enables cost-saving and efficient production of the components.
  • the upper chord and the lower chord are arranged one above the other at a distance which essentially corresponds to the width of the longitudinal member transversely to the central longitudinal axis.
  • the cross section of the longitudinal beam can essentially have the shape of a box-shaped, in particular a square, hollow profile. This ensures a particularly high strength of the side member.
  • the upper chord and the lower chord are selectively connected via angle struts.
  • At least four angled struts can preferably be provided, two angled struts preferably being arranged on each side of the longitudinal beam.
  • the angle struts can be arranged approximately in a range of 30% -70% of the length of the longitudinal member and preferably symmetrically along the central longitudinal axis in order to achieve a particularly good distribution of the load.
  • the angled struts can in particular be K-shaped, with two ends being arranged on the upper chord and two ends on the lower chord. This ensures a particularly good introduction of force.
  • each of the two head pieces is connected to the upper belt and the lower belt via two separate longitudinal webs, the longitudinal webs running essentially parallel to one another and being arranged essentially normal to the loading area. This ensures that the forces introduced into the head piece, in particular tensile forces, are efficiently passed on to the longitudinal member.
  • the longitudinal webs are preferably in one piece.
  • the longitudinal webs are essentially Y-shaped, each with three longitudinal web ends, a first longitudinal web end being connected to the upper chord, a second longitudinal web end being connected to the lower chord and a third longitudinal web end being connected to the head piece.
  • This special shape of the longitudinal webs eliminates the need for further welding seams, since the shape of the longitudinal webs is already adapted to the special design of the upper and lower chords. In order not to impair the high strength and robustness of the longitudinal webs, they run as a direct extension of the longitudinal member into the head pieces and are welded to them.
  • the first longitudinal web end is connected to the second longitudinal web end via a material web.
  • the longitudinal webs are slightly curved and widen somewhat in the direction from the longitudinal beam to the head pieces.
  • the longitudinal webs are curved at an angle of approximately 5 ° from the third longitudinal web end in the direction of the first and second longitudinal web end.
  • the upper chord and preferably also the lower chord are each formed by a one-piece profile part.
  • These profile parts can preferably be essentially flat.
  • the upper chord and preferably also the lower chord are formed by several, preferably four, material stiffeners running parallel to one another along the central longitudinal axis and connected by channel-shaped depressions, in particular beads, the distance between them preferably about 30% to 70%, especially is preferably about 50% of its extent transversely to the central longitudinal axis.
  • the upper belt preferably has two stiffening ribs running parallel to one another along the central longitudinal axis and extending downward normal to the loading area on its underside. This achieves a particularly high level of strength.
  • the extension of the stiffening ribs normal to the loading area downwards can be about 10% to 20% of the width of the loading area.
  • the stiffening ribs can preferably be arranged distributed uniformly on the underside of the upper chord.
  • the head pieces and the longitudinal member are designed essentially symmetrically to the central longitudinal axis of the longitudinal member.
  • the head pieces have at least three material cutouts separated by material webs, each of which extends from the area of the buffer chest in the direction of the longitudinal member and tapering in this direction.
  • the material recesses allow a reduction in the material required and thus a significant saving in weight.
  • the head pieces taper from the area of the buffer chest in the direction of the longitudinal member to form a tapered area.
  • at least two material cutouts can be provided, which also taper in this direction and are preferably essentially triangular.
  • the tapering of the head pieces ensures a seamless transition from the narrow side member to the head pieces with a standard width.
  • the material recesses in turn allow a weight reduction while maintaining the same strength.
  • the head pieces taper from the area of the buffer chest in the direction of the longitudinal beam in the plane defined by the loading area to 20% to 70%, preferably about 40% of their extension transversely to the central longitudinal axis. This corresponds to the width of the longitudinal member, so that a direct transition from the head piece to the longitudinal member is achieved.
  • the head pieces each have a non-weakened area for the arrangement of rotary sockets, which extends transversely to the central longitudinal axis, preferably over the entire width of the head pieces, and in which no material recesses are provided.
  • the head pieces taper in their extension transversely to the central longitudinal axis from the area of the buffer chest in the direction of the longitudinal beam, preferably only from the end of the non-weakened area, so that the full strength of the material is retained in the non-weakened area.
  • the non-weakened areas each extend along the central longitudinal axis essentially over 10% to 20%, preferably about 15% of the length of the head pieces. This gives sufficient leeway for fastening the rotary pans in the non-weakened area.
  • the non-weakened areas are provided essentially centrally along the central longitudinal axis with respect to the length of the head pieces.
  • the rotary pans can thus be arranged centrally in relation to the length of the head piece.
  • non-weakened areas offset by about 2% to 10% of the length of the head pieces in the direction of the longitudinal beam.
  • At least one cross arm with two carriers can be provided on the longitudinal carrier, the carriers each having container pins and extending essentially transversely to the central longitudinal axis. These container pins are used to fix the position of containers and / or superstructures on the longitudinal beam.
  • a one-piece, shaped carrier profile is arranged on the sides of the head pieces for stiffening, which serves to optimally guide the buffer forces from the buffer chest into the main cross member.
  • a one-piece cover plate is arranged on the upper side of the head pieces, which cover plate serves to optimally guide the buffer forces from the buffer chest into the longitudinal member.

  • Fig. 1 shows a schematic three-dimensional representation of an embodiment of a platform trolley according to the invention.

  • the taper is about 40% of its extent transverse to the central longitudinal axis 7, in other words the extent of the Head pieces 2a, 2b in the area of the transition to the longitudinal beam 5 are only 40% of their extent in the area of the buffer chest 3a, 3b.
  • the tapering begins, however, only after the non-weakened area 16a, 16b.
  • the head pieces 2a, 2b thus taper from the area of the buffer chest 3a, 3b in the direction of the longitudinal member 5 only from the non-weakened area 16a, 16b, so that the full width of the head pieces 2a, 2b is available for the rotary sockets 17a, 17b.
  • the transverse arms 18 are arranged on the upper chord 8 and are supported on the lower chord 9 via cross struts 21a, 21b.
  • FIG. 6b shows a view of the underframe 1 according to the invention from above.
  • the underframe 1 comprises two head pieces 2a, 2b, each with a buffer chest 3a, 3b and buffers 4 arranged thereon. Between the head pieces 2a, 2b, a longitudinal beam 5 extends symmetrically along a central longitudinal axis 7.
  • the longitudinal beam 5 forms a loading area 6 for supporting containers and / or superstructures, the loading area 6 being formed by the surface of the upper belt 8.
  • the head pieces 2a, 2b and the longitudinal beam 5 are designed essentially symmetrically to the central longitudinal axis 7.
  • the head pieces 2a, 2b comprise several material recesses 13a, 13b, 13c separated from one another by material webs, which each extend from the area of the buffer chest 3a, 3b in the direction of the longitudinal member 5 and taper in this direction.
  • the head pieces 2a, 2b themselves also taper from the area of the buffer breast 3a, 3b in the direction of the longitudinal member 5.
  • at least two further material recesses 15a, 15b are provided, which also taper in this direction and are essentially triangular .
  • the head pieces 2a, 2b taper from the area of the buffer breast 3a, 3b in the direction of the longitudinal beam 5 to about 40% of their extent transversely to the central longitudinal axis 7.
  • the non-weakened area 16a, 16b each extends transversely to the central longitudinal axis 7.
  • the head pieces 2a, 2b taper from the area of the buffer breast 3a, 3b in the direction of the longitudinal member 5 only from the non-weakened area 16a, 16b.
  • the non-weakened areas 16a, 16b each extend along the central longitudinal axis 7 essentially over approximately 15% of the length of the head pieces 2a, 2b and slightly along the central longitudinal axis 7 in relation to the length of the head pieces 2a, 2b are provided offset in the direction of the longitudinal member 5.
  • transverse brackets 18 with the container pins 20a, 20b arranged thereon.
  • the container pins 20a, 20b are used to hold containers and / or superstructures.
  • the transverse arms 18 include supports 19a, 19b, which are arranged on the upper chord 8 and extend essentially transversely to the central longitudinal axis 7.
  • cross struts 21a, 21b are provided which support the carrier 19a, 19b on the lower chord 9.
  • Figure 6c shows a view of the underframe 1 from the side. It can be seen in this view that the longitudinal beam 5 defines a loading area 6 for the arrangement of containers and / or superstructures. It can also be seen that the longitudinal beam 5 comprises an upper belt 8 and a lower belt 9, which are arranged one above the other and are connected to one another and to the head pieces 2a, 2b at their ends via longitudinal webs 10a, 10b.
  • the upper chord 8 and the lower chord 9 are essentially identical in construction.
  • the upper chord 8 and the lower chord 9 are arranged one above the other at a distance which essentially corresponds to the width of the longitudinal beam 5 transversely to the central longitudinal axis 7, so that the longitudinal beam 5 has the shape of an essentially square hollow profile.
  • the upper chord 8 and the lower chord 9 are selectively connected to one another via the angled struts 22a, 22b, 22c, 22d.
  • the longitudinal webs 10a, 10b, 10c, 10d are Y-shaped, each with three longitudinal web ends 11a, 11b, 11c.
  • One longitudinal web end 11a is connected to the upper chord 8
  • a second longitudinal web end 11b is connected to the lower chord 9
  • a third longitudinal web end 11c is connected to the head piece 2a, 2b.
  • the ends of the longitudinal webs are connected to one another via struts.
  • transverse brackets 18 which are connected to both the upper chord 8 and the lower chord 9 and have container pins 20a, 20b on their upper side or in the area of the loading area 6 for receiving containers and / or superstructures.
  • Fig. 6d shows a schematic view of the underframe 1 according to the invention from the side, the buffers 4 and the buffer breast 3a being visible. Furthermore, the cross struts 21a, 21b for supporting the cross arms 18 are visible. Finally, it can be seen in this illustration that the longitudinal webs 10a, 10b run essentially parallel to the central longitudinal axis 7 of the longitudinal member 5. A lower part 23 is provided on the underside of the head piece 2a. The container pins 20a, 20b can also be seen in this illustration.
  • Figure 6e shows the in Figure 6c indicated section BB in a schematic representation.
  • the section runs transversely through the head piece 2a and the longitudinal webs 10a, 10b. Again, the cross struts 21a, 21b of the cross arm 18 can be seen.
  • the lower part 23 can be seen on the underside of the head piece 2a.
  • a shaped carrier profile 24a, 24b is arranged on the sides of the head piece 2a to increase the stability and to optimally introduce the buffer forces into the main cross member.
  • Fig. 6f shows a schematic representation of the in Figure 6c defined section CC, which runs in the region of the longitudinal member 5.
  • the upper chord 8 and the lower chord 9 form an essentially square hollow profile.
  • the loading area 6 defined by the upper side of the upper belt 8 and the transverse arm 18 with the transverse struts 21a, 21b.
  • the lower part 23 arranged in the area of the head piece 2b can be seen.
  • This lower part 23 also has material cutouts to reduce weight.
  • the distance between the upper chord 8 and the lower chord 9 essentially corresponds to the width of the longitudinal member 5 transversely to the central longitudinal axis 7.
  • the stiffening ribs 26a, 26b of the upper chord 8 can also be seen in this illustration.
  • the two stiffening ribs 26a, 26b are arranged on the underside of the upper belt 8 and run parallel to one another along the central longitudinal axis 7 and extend downward normal to the loading area 6.
  • Figures 7a-7b show views of a longitudinal web 10a of an underframe according to the invention from the side and from above. It can be seen that the longitudinal web 10a is Y-shaped, each with three longitudinal web ends 11a, 11b, 11c. To increase the stability, the first longitudinal web end 11a is connected to the second longitudinal web end 11b via material struts.
  • the longitudinal web 10a is slightly curved in order to widen slightly in the direction from the longitudinal member to the head pieces.
  • the longitudinal web 10a is curved from the third longitudinal web end 11c in the direction of the first longitudinal web end 11a and the second longitudinal saw end 11b at an angle of approximately 5 °.
  • the underframe in question was the result of a cooperation between Rail Cargo Wagon - Austria GmbH and the voestalpine Group, in particular the voestalpine Steel Division and the voestalpine Metal Forming Division.
