A first plate body and a second plate body of the rib plate are connected from head to tail, and meanwhile, the connection part is provided with lap joint parts in a staggered lap joint mode; a weld line extending along at least one edge is arranged between the two lap joint parts, so as to enable the first plate body and the second plate body to be welded and connected fixedly via the weld line, so that when the rib plate is welded, after the first plate body and the second plate body are configured according to the sequence of connection from head to tail, and then the adjacent parts of the first plate body and the second plate body are overlapped with each other; the edges at the lap joint parts are welded, and then the first plate body and the second plate body are welded and fixed together; the lap joint parts on the first plate body and the second plate body have the mutual constraint effects, and buckling deformation caused by the lack of constraint of at least one of the first plate body and the second plate body in the welding process is avoided, so that the manufacturing precision of the whole rib plate is improved, and the quality of whole box type girder is improved.
Description
Technical field
The present invention relates to a kind of gusset and use box beam, the hoisting crane of this gusset.
Background technology
Box beam structure is the keystone configuration of hoisting crane, it is the load bearing component of hoisting crane key, it mainly contains upper and lower cover plates, web, the compositions such as gusset, gusset is by upper, lower cover forms the strength member of stable load-carrying element together with web compact siro spinning technology, its definitely many distributed number is in whole box beam, its physical dimension accuracy rate directly affects the accuracy to size of box beam, its build guality directly has influence on the quality of box beam, namely directly have influence on the load-carrying capacity of box beam, finally have influence on hoisting crane quality, therefore the structure design of box beam gusset, manufacturing technology is very important.Through the mechanical analysis of system in order to obtain the overall weight of increase box beam that namely can not be undue, the best resultant effect of carrying needs can be met again, in industry usually employing be hollow structure gusset, Fig. 1, Fig. 2 are the version generally adopted.
Fig. 1 structure is the punching-type gusset 10 that centre cutting or punching press are fallen by the monoblock steel plate adopted, this structure has two problems: one be centre remove part steel will become waste material, steel waste greatly, will increase cost of product undoubtedly, reduce the market competitiveness; Second Problem removes that centre portion shop characteristic is poor, efficiency is low, workman's labor condition is poor, production tooling cost is high.This structure mainly contains two kinds of process manufactures at present and obtains, and a kind of process adopts gas flame cuttiug, and this technique worker laboring environment is poor, and efficiency is too low; Another kind of technique adopts Sheet Metal Forming Technology, and the shortcoming of this technique is that equipment investment and frock investment are comparatively large, increases production tooling cost again undoubtedly.
Fig. 2 structure is the butt joint type gusset 20 docked by four blocks of plates, it is docked by two pieces of transverse slats 21 and two pieces of risers 22, butt seam is welding road, also there is two problems in this version, a problem is that weld seam is on butted line, during welding, two pieces of risers 22 are heated inequality very easily corrugation warpage, and oad is difficult to ensure, directly affects the combination quality of box beam; Second Problem fusion length is shorter, and weld seam carrying shear ability is poor, affects box beam total quality.
Summary of the invention
The object of this invention is to provide the gusset that a kind of welding precision is high, additionally provide a kind of box beam, the hoisting crane that use this gusset simultaneously.
In order to realize above object, in the present invention, the technical scheme of gusset is as follows:
