Abstract
The utility model discloses a web member on a boom crane, and relates to a boom crane. The web member has the advantages of short node distance, light weight and high strength. The web member comprises an upper chord member, a lower chord member and a web member, wherein a fixed web member is welded in the center position of the triangular structure; a gusset plate is welded at the center of the web member; a stay web member is welded on the gusset plate; and a vertical web member is welded in the direction vertical to a fixing plate. Compared with the present triangular web member, the web member has higher strength, higher stability and wider material range, such as angle iron, channel beam, H-shaped steel, round tube and square tube. In addition, the node distance of the web member is reduced by 50%, the weight is reduced by 10% to 15%, and the material utilization rate is improved by 5% as compared with the present web member.
Description
Technical field:
The utility model relates to boom crane, is specially adapted to large-tonnage and hoists.
Background technology:
Web member on the existing boom crane is to adopt triangle to be connected with upper and lower chord member, thereby causes the web member nodal distance to influence intensity and stability greatly.
Summary of the invention:
Task of the present utility model is to propose a kind of shortening nodal distance, the web member that the boom crane of reduce weight, gaining in strength is above.Task of the present utility model is finished like this, it comprises upper and lower chord member and web member, it is characterized in that: be welded with stable web member on leg-of-mutton center, the center of web member is welded with gusset plate, be welded with on the gusset plate and tiltedly draw web member, vertical fixing plate direction is welded with vertical web member.Two end points stablizing web member are welded in respectively on the upper and lower chord member.Be welded with on the gusset plate tiltedly to draw and constitute little triangle behind the web member, the both sides of described stable web member are tiltedly to draw the web member end points to be welded on the lower boom jointly.The utlity model has following effect: the utility model has shortened half than existing triangular web member nodal distance, guaranteed the intensity of web member, improved stability, weight saving 10-15%, stock utilization improves 5%, the material that uses is comparatively extensive, available angle bar, channel-section steel, H shaped steel, pipe and square tube etc.
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, stablize web member 5, gusset plate 6, vertically web member 7, tiltedly draw web member
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, on leg-of-mutton center, be welded with and stablize web member 4, this web member two-end-point and 1,2 welding of upper and lower chord member, be welded with gusset plate 5 in the center of web member 3, be welded with one on the adapter plate and tiltedly draw web member 7, constitute little triangle, little leg-of-mutton center vertical fixing plate direction is welded with vertical web member 6, the both sides of stabilizer rod 4 are web members 3, and end points is welded on the top boom jointly, and this structure has enough intensity and stability.
