轴系、舵系中心线确定及艉管环氧浇注工艺english

四．艉轴艉管校中及其固定 ALIGNMENT AND FIXING OF STERN TUBE

4.1 艉管就位POSITIONING OF STERN TUBE

4.1-1: 艉管就位条件 PREPARATION OF STERN TUBE POSITIONING

A.艉管中心线的找正 DECIDING OF STERN TUBE CENTERLINE

A.1 将艉管布臵于车间平台上保持水平;

PLACE STERN TUBE HORIZONTAL ON PLATFORM IN WORKSHOP

A.2 根据艉管前后φ655孔中心线在艉管前后端面上在水平方向及垂直方向上划出水平

线和垂直线并打好洋冲眼, 那么前后艉管端面的十字线的交点的连线即为艉管外圆的理论中心线. 完工成后需交船东船检认可.

DRAW A HORIZONTAL LINE AND A VERTICAL LINE ACCORDING TO THE

CENTERLINE OF φ655 HOLE AT STERN TUBE FORE AND AFT. END, AND

MAKE A MARK, SO THE LINE BETWEEN THE TWO INTERSECTION POINTS

STATED ABOVE IS THE THEORY CENTERLINE OF S/T OUTER CIRCLE, AND

SHOULD BE APPROVED BY SHIPOWNER AND SURVEYER.

B.在本工艺进行的过程中,船上应停止冲击和有振动的工作.

WHEN THIS STEP IS BEING DONE, ANY IMPACTING WORK OR VIBRATION JOB SHOULD BE STOPPED.

4.2 艉管就位 POSITIONING OF STERN TUBE

A.按“浇注环氧总装图”将八只艉管调整螺栓(图6)预先布臵到相应位臵处, 螺栓头部应

不伸入支撑套内部以免影响艉管放入;

PREPLACE 8 PCS JACKING SCREWS (DRAWING 6) AT THE CORRESPONDING

POSITION ACCORDING TO “POURING EPOXY ASSEMBLY” DRAWING.

B.按“环氧浇注总装图”焊好前后艉管支撑套上的四个透气管及二个注入管.注入管及透

气管均采用φ27X2.5无缝钢管.钢管上应无任何油漆,油污等;

WELD THE 4 PCS AIR VENT PIPES AND 2 PCS FILLING PIPES ON THE FWD AND AFT STERN OUTER BOSSES ACCORDING TO THE “POURING EPOXY ASSEMBLY”.

THE FILL AND VENT PIPES IS SEAMLESS STEEL PIPE OF φ27X2.5, WITHOUT

ANY PAINT AND OIL ETC.

C.为防止艉管塞入支撑套后发生轴向位移,需按附图9制作一根法兰面压板, 并根据图9中

所示位臵焊好固定螺栓M24;

MAKE 1 PC STOPPING PLATE BY CHANNEL STEEL FOR PREVENTING THE

MOVEMENT ALONG THE SHAFT LINE AFTER PUSHING THE STERN TUBE INTO THE STERN FRAME BOSS, SEE DRAWING 9, AND WELD THE FIXING SCREW M24 AS DRAWING 9.

D.根据“浇注环氧总装图”安装密封板(图5);

INSTALL SEALING PLATE (DRAWING 5) ACCORDING TO THE “POURING EPOXY ASSEMBLY” .

E.准备至少六只工作载荷为4.5吨的手拉葫芦.

PREPARE AT LEAST 6 PCS CHAIN BLOCKS WHOSE WORK LOAD IS 4.5 TON.

F.将艉管放至图7中所示位臵, 艉管上下方向需按轴系布臵图摆正,调节小车上下水平位臵

使得艉管中心线与轴理论中心线平行.

PUT STERN TUBE TO THE PLACE SHOWN ON DRAWING 7, ADJUST IT ALONG VERTICAL DIRECTION AS SHAFTING ARRANGEMENT DRAWING, AND ADJUST THE TROLLEY UNTIL STERN TUBE CENTERLINE PARALLEL WITH SHAFT

THEORY CENTERLINE.

G.将提升杆装至艉管的艏端,提升杆和艉管接触部份均需用铜皮衬垫以防划伤艉管内表面

并用铜螺栓紧固好（图8）. 检查艉管清洁度. 艉管前后支撑套内表面及艉管外表面等与环氧树脂接触处(含浇注孔,透气孔内表面)均需清除铁锈,油污,毛刺,焊渣,油漆和灰尘等.

提交维信服务工程师检查清洁并满足要求;

INSTALL LIFTING ROD TO THE FWD STERN TUBE, ADD BRASS PAD AT

CONTACT PART BETWEEN LIFTING ROD AND STERN TUBE PREVENTING FROM SCUFFING THE INNER SURFACE OF STERN TUBE AND FIX WITH BRASS SCREW (DRAWING 8).
