Abstract
|
Rotary drilling rig due to the complex and changing of operating conditions and operating conditions , thus easily lead to many difficult problems . Quality and technical performance of the the domestic rotary drilling rig up to less than the level of customer satisfaction , structural design and manufacturing process analysis and research of rotary drilling rig , to accelerate the domestic research and development of this product and its early localization series of tasks is imminent. NR220 rotary drilling rig mast structure analysis and welding process \Using three-dimensional modeling software PRO / E mast solid modeling and finite element analysis software PRO / MACHANICA mast finite element analysis, the calculation results . NR220 rotary drilling rig actual working conditions , analysis the mast breakage causes of the accident , and discusses the methods of how to prevent the mast fracture . According to the results , the weak parts of the mast improvement program has been successfully applied in the mass production of rotary drilling rig NR220 . The same time, the mast welding deformation occurred in the manufacturing process , by finding the prevention and correction of welding deformation some effective measures to study the large-scale structure of the welding manufacturing technology to find ways to improve the level of plant structural parts manufacturing methods and experience . In conclusion, the article also discusses the design methods and basic principles of rotary drilling rig mast tailor welded tooling .
