Description
Technical field
The present invention relates to a kind of drawing methods of bridging crane main beam, and in particular to a kind of to utilize AutoCAD
The method that quick 1:1 draws bridging crane main beam two-dimensional engineering graphic.
Background technique
Currently under the influence of state macro-control policy and equipment manufacture development plan, China's hoisting machinery equipment system
It makes industry and enters Rapid development stage.The specification of crane is various, the complicated multiplicity of structure, mechanism, and each interstructural relationship is multiple
Miscellaneous, design efforts would is very heavy.Vibrative mechanism is the main component of crane bearing load, by fashioned iron and steel plate as base
This component is connected using the methods of riveting, welding according to certain structure type.Metal structure (the bridge of bridge crane
Frame) mainly by girder, end carriage, railing, walk on stage, the components such as track and drivers' cab form.Girder is main as bridge crane
Load component, performance will affect the overall performance of entire crane.The two-dimensional engineering graphic of girder is usually manual by staff
It is drawn in AutoCAD software, for the girder of same type different size, will draw, mark again again, process is cumbersome,
It wastes time.And the girder drawing in producing, in order to protrude the details of certain components, it will usually destroy integrally-built ratio
Example, not can truly reflect main beam structure.And due to the limitation of paper size, some small structures on girder cannot be schemed again
It is clearly expressed on paper.In view of the above-mentioned problems, the present invention has studied the design method and engineering drawing of bridging crane main beam structure
The key technology of drafting.
Summary of the invention
The technical problem to be solved by the present invention is to overcome above-mentioned deficiency, provide a kind of using Visual Basic language volume
The method that system draws bridging crane main beam two-dimensional engineering graphic using the quick 1:1 of AutoCAD, the overhead traveling crane provided according to user
Main beam structural parameters draw the bridging crane main beam two-dimensional engineering graphic that ratio is 1:1 automatically, can be in AutoCAD software
It easily checks the content expressed on drawing, including the basic structure of girder, track, fashioned iron, door, pedestal, connecting plate, hangs
Ear, weld seam, threaded hole, chamfering and fillet, can truly reflect main beam structure；Overhead traveling crane owner can also be reduced to greatest extent
The drafting time of beam two-dimensional engineering graphic, the effective efficiency for improving designer are big further according to drawing when needing to print drawing
It is small, ratio is adjusted separately to the structure of primary structure and micro-member.
Technical scheme is as follows:
A method of bridging crane main beam two-dimensional engineering graphic being drawn using the quick 1:1 of AutoCAD, including is walked as follows
It is rapid:
