Abstract
The invention discloses a kind of large-size box structure, (such as bridging crane main beam span is generally more than 10 meters to the problem for changing greatly for different body structure appearance and sizes, and forging press sill length is then much smaller), the feature that topological optimization obtains structure is carried out to different size body structure, it is such large-size box structure to extract both common characteristics.The large-size box structure is suitable for geometric shape for hollow cuboid, and inside has complicated reinforcing plate structure to arrange, bottom section is constrained, and load, the overall stand under load operating mode body structure similar to simply supported beam are born in upper surface.The large-size box structure provides reference for class formation processing and manufacturing.
Description
Technical field
The present invention relates to a kind of large-size box structure, predominantly such structural seriesization design provides reference.
Background technology
Large-size box structure is widely used in industrial equipment, for example main beam of gantry crane, bed piece, forging equipment
Crossbeam etc.；Large-size box structure occupies most of volume and quality of equipment, and carrying effect is played in a device, decides and sets
The basic parameter such as standby maximum working ability and load capacity.
At present, large-size box structure Main Basiss experience and Analogy are designed, cause such construction weight and volume compared with
Greatly, box house rib plate layout and thickness do not have scientific theory foundation, and stock utilization is relatively low；Advocating environmental protection, saving
Today of resource, on existing performance basis are ensured, if heavy large-size box structure can mitigate some weight in equipment, that
In the fabrication process will material-saving, during transport and use will save energy, therefore the invention discloses one kind
Large-size box structure, for class formation processing and manufacturing provides reference.
The content of the invention
It is excellent by carrying out to different size body structure topology it is an object of the invention to provide a kind of large-size box structure
Change the feature for obtaining structure, it is such large-size box structure to extract both common characteristics, obtains making this class formation meet work at it
On the premise of journey use requirement, mitigate large-size box deadweight, improve stock utilization, reduce production cost.
To achieve these goals, it is that the hollow rectangle cuboid simply supported beam that wall thickness is 8mm carries out topological optimization to structure
Each 20mm regions in bottom at design, cuboid or so two ends are subject to staff cultivation, and load is born in cuboid upper end；Load is added respectively
At large-size box left, center, right end, the difference according to load loading position draws different topological structures, extracts each respectively
The total feature of topological structure is such large-size box structure.
By being welded between each part of large-size box structure.
The large-size box overall structure is segmented into two large divisions：Intermediate host structure and left and right two ends supporting construction.
The large-size box structure two ends supporting construction is inclined, and the upper and lower material in two ends supporting construction part gone
Remove, make structure generally trapezoidal shape, the hole below supporting construction is also trapezoidal.
The large-size box structure intermediate body portions are divided into inverted trapezoidal structure wide at the top and narrow at the bottom, and front-rear center position is distinguished
There is a larger hole.
The web overall structure of the large-size box structure is in similar to M shapes.
The large-size box structure upper cover plate is divided into three parts：The upper cover plate at two ends and the upper cover plate of center section, wherein
Two ends are used for enhancing structure entirety stress-bearing capability in the upper cover plate of strip.
The large-size box structure lower cover is equally split into three parts：The lower cover at two ends and the lower cover of center section.
Brief description of the drawings
Fig. 1 is two isogonism axonometric drawings of left and right of the invention.
Fig. 2 is front view of the invention.
Fig. 3 is top view of the invention.
Fig. 4 is right view of the invention.

Specific embodiment
The present invention is further described through below in conjunction with the accompanying drawings：
The large-size box structure is that the wall thickness of body structure is set for the hollow rectangle cuboid simply supported beam of 8mm carries out topological optimization
What meter was obtained；Each 20mm regions in bottom at cuboid or so two ends are subject to staff cultivation, and load is born in cuboid upper end；To carry respectively
Lotus is added in large-size box left, center, right end, and the difference according to load loading position draws different topological structures respectively, extracts
The total feature of each topological structure is such large-size box structure.
As shown in figure 1, a kind of large-size box structure, large-size box structure welded by upper cover plate 1, lower cover 2, web 3 and
Into.
Wherein upper cover plate is divided into three parts：Left and right two ends in strip upper cover plate 1 and center section upper cover plate 1, its
Middle left and right two ends are used for enhancing structure entirety stress-bearing capability in the upper cover plate 1 of strip；Lower cover is equally split into three parts：Left and right
Two ends are in the lower cover 2 of strip and the lower cover 2 of center section；It is in similar to M shapes that web 3 is overall.
The large-size box overall structure is segmented into two large divisions：Intermediate host structure and left and right two ends supporting construction；In
Between main part be inverted trapezoidal structure wide at the top and narrow at the bottom, and there is a larger hole front-rear center position respectively；Two ends branch
Support structure is inclined, and the upper and lower material in two ends supporting construction part is removed, and makes structure generally trapezoidal shape, support knot
Hole below structure is also trapezoidal.
The problem that the present invention is changed greatly for different body structure appearance and sizes, opens up to different size body structure
The feature for optimizing and obtaining structure is flutterred, it is such large-size box structure to extract both common characteristics, be that geometric shape is hollow rectangular
Body, inside has complicated reinforcing plate structure to arrange, bottom section is constrained, and load, overall stand under load operating mode and simply supported beam are born in upper surface
Similar body structure processing and manufacturing provides reference.
Foregoing description of the present invention gives basic structure of the invention, and any those of ordinary skill in the art can be according to case
Body structure stress situation arranges gusset in the large-size box inside configuration, as long as do not depart from that technical spirit of the invention made appoints
What simple change, still falls within the scope of the present invention.
