轴线照光工艺

轴线照光工艺 轴线照光工艺 27000DWT轴线复照光工艺 270000DWT process of shaft alignment by optical method 因尾部节能装置修改，焊接有可能会引起尾管轴线变形，因此需对轴线进行 Because the energy saving device was modification, maybe, welding could bring 复检。由于目前正在对尾管进行镗孔，镗排中心与尾管同心，可根据镗排中心 distorting of the shaft line. So must be measure again, and now the stern φ54mm圆孔对轴线进行检验，具体照光程序如下： tube has been boring, and the boring stock is the same center with the stern tube. We can check up the shaft line according the hole of the boring stockφ54mm with the laser bean. The process of shaft alignment by optical method as follows: 1、​ 在尾标杆前处设置激光经纬仪，并以标杆和原始船台中心线为基准，用激光复检镗排中心与船台中心的偏差。 Put laser light instrument on the floor, and check the center of shaft alignment according originality the center of the hull and surveyor's pole. 2、​ 在机舱内尾管前端与主机后端中间船体中线位置设置刚性经纬仪座，以尾部标杆上原始轴线的十字线和机舱内的纵桁、内底、FR12舱壁上原洋冲标记为基准，调整光点使之高度及中心与之吻合。 Adjust the laser light instrument of engine room according the laser bean superposition with the center of hull、base line、the mark of FR12. 3、​ 将机舱内激光经纬仪的光点打至尾标杆，以测量镗排前、后端圆孔中心与光点的偏差。 Measure data the bow and stern of circle hole by the laser bean (refer to the sketch 1 ). 船体工艺科 hull technologic department 2001-12-13
