- 摘要:
- 在升降式作业平台的升降过程中,为保证平台的稳定性,齿轮齿条的啮合精度必须控制在一个很小的误差范围内,这就对桩腿齿条预制安装过程中的焊接质量和尺寸控制提出了很高的要求。文章从桩腿的形式、焊接难点、齿条焊接工艺、焊材选用、坡口设计和焊接顺序、焊接工艺参数、焊接工艺评定、桩腿与齿条预制尺寸控制等方面对其进行了论述。
During ascending or descending of a jack-up operation platform,meshing precision between gears and racks must be controlled within a small error range to ensure the platform stability.It demands the high welding quality and exact dimension of pile-leg racks in prefabrication and installation.This paper discusses the following aspects: pile-led form,welding difficulty,rack welding process,welding material selection,bevel design,welding sequence,welding process parameters,welding process assessment,dimension control in pile-leg and rack prefabrication,and so on.2011,3(3): 27-30 收稿日期：2010-11-29分类号：TE951作者简介：贾芳民(1965-),男,山东滨州人,高级工程师,1990年毕业于石油大学(华东),现从事工程项目管理工作.参考文献：
