Abstract
The utility model discloses a web member on the truss dual-girder of a gantry crane. The utility model realizes the goal providing the web member on the truss dual-girder of the gantry crane, wherein the web member has the advantages that the weight is reduced, the cost is decreased and even bearing stress is guaranteed. The technical scheme is that the web member comprises an upper chord member, a lower chord member, a supporting web member is longitudinally welded in the area of the upper chord member and the lower chord member, a gusset plate is welded in the center of the supporting web member, and inclined web members are welded at the four corners of the gusset plate. By adopting the technical scheme, the utility model has the advantages of reduced weight, decreased cost, even bearing stress and safe operation.
Description
Technical field:
The utility model relates to the web member on the two girders of a kind of gauntry crane Yan frame, is specially adapted to overlength, the two girder gauntry cranes of super large.
Background technology:
Web member on the existing gauntry crane Yan frame girder mostly is to adopt whole web member to be connected with chord member, and its shortcoming is: because span is big between the chord member, thus require the web member material also need strengthen thickening, thus weight increased, increased cost.
Summary of the invention:
Task of the present utility model is to propose a kind of expendable weight, and cost-cutting ensures the web member on the two girders of stressed uniform a kind of gauntry crane Yan frame.Technical solution of the present utility model is that it comprises upper and lower chord member, it is characterized in that: the regional lengthwise position of upper and lower chord member is welded with the support web member, is welded with gusset plate on the center of support web member, is welded with on four angles of gusset plate and tiltedly draws web member.Described support web member two ends are welded on the upper and lower chord member, tiltedly draw web member to be made up of respectively 4 short roots and weld with upper and lower chord member.The utlity model has following effect: adopt the technical solution of the utility model, the one, the energy expendable weight, cost-cutting, the 2nd, stressed even, operation ensures safety.
Description of drawings:
Fig. 1 is the prior art constructions scheme drawing.
Fig. 2 is a structural representation of the present utility model.
Drawing explanation: 1, lower boom 2, top boom 3, web member 4, gusset plate 5, support web member 6, tiltedly draw web member
The specific embodiment:
Make specific embodiment in conjunction with above accompanying drawing: existing upper and lower chord member is welded with web member 3 (see figure 1)s for 2,1 li, be welded with on the lengthwise position in the zone of top boom 2 and lower boom 1 and support web member 5, the two ends of supporting web member 5 are welded on the upper and lower chord member 2,1, the center of supporting web member 5 is welded with gusset plate 4, be welded with on four angles of gusset plate and tiltedly draw web member 6, gusset plate is a square shape, tiltedly draw web member 6 to form by 4 short roots, respectively with upper and lower chord member 2,1 welding, its objective is stressed even, expendable weight, cost-cutting.
