Description
Technical field
The invention belongs to large-size cylinder body package technique field, be specifically related to a kind of large-size cylinder body and hold round and the mounting process method of angle ring and assembly equipment thereof.
Background technology
For raising large-size cylinder body, tank body rigidity often need to increase multiple angle ring in inside and forms ring-type muscle, simultaneously, when diameter 3m ~ 7m large-size cylinder body corner of workpiece steel ring is installed, enough circularity is had for the ease of the installation of angle ring and cylindrical shell, improve the quality of follow-up welding technique, also need hold round cylindrical shell or bind round round operation.
In prior art, following methods is taked to the process of large-size cylinder body: first complete cylindrical shell blanking, plane limit and volume circle, after longitudinal seam welding operation, cylindrical shell hangs onto on turning rolls by workman again, because cylindrical shell does not now also fill stiffening ring, itself is affected by gravity, become irregular ellipticity, workman needs first according to the size of cylindrical shell size for this reason, select suitable cranse frock, by cylindrical shell two ends hoop circle, then the angle ring of ground stacking is lifted by two workmans, enter into cylindrical shell, because angle ring size is consistent with cylinder internal diameter, angle ring often can be stuck in certain position of cylindrical shell on the way, now must by manually hitting with a hammer, precalculated position could be arrived smoothly, spot welding is rotated again after having assembled.There is following problem in the method:
1. loaded down with trivial details, the inefficiency of whole process: combined type cranse is spliced by multi-section circular arc, also needs adjusting position after closing up between each section, and then bolt tightening, driving lifting times is many, installs length consuming time.Labour intensity is large, and need for each workpiece prepares a set of cranse frock, frock quantity is various, particularly large-size cylinder body as 6, the workpiece of 7m diameter, its cranse frock weight is large, deposits and lift all to have problems, and the operation of hoop circle will become very difficult, even cannot manually complete.
2. adopt the method for outer hoop to hold round frock to cylindrical shell, do not have interior hoop quality good from technique.The phenomenon of indent may be there is in local.
3. adopt and manually lift angle ring into cylindrical shell, and knock assembling on the way, labor strength is large, inefficiency, and noise is large, in career safety & health, there is larger hidden danger.If particularly barrel diameter is large, such as more than 5m specification, its angle ring weighs three, 400 kilograms, manually cannot realize the operation be seated by angle ring at all.
4. adopt and manually knock assembling, angle ring and cylindrical shell are fitted poor.There is depression cavitation local, and even angle ring may be crooked, affects the quality that product is final.
To sum up, the cylindrical shell that current industry generally uses holds round and angle ring installation method has been not suitable with the needs of modern production, even production can not be completed for large-size cylinder body, be badly in need of improving cylindrical shell production technology, overcome above-mentioned defect, meanwhile, also should improve corresponding assembly equipment, to adapt to the improvement needs of production technology.
