Specifically, the installation for Double gear box pedestal includes the following steps:
1, the total packet size of block is adjusted within the scope of precision controlling
EBZ02 block ensures the high level of synchronization of port and starboard FR42# rib position, and the gear cage base pit levelness of two sides of a ship when always organizing
It is adjusted within the scope of precision controlling, corresponding region is resized to meet gear-box base according to the data on total group positioning figure
Seat positioning requirements；
2, segmentation axial line is marked
Two segmentation axial lines are marked on EB02P/S inner bottom plating according to EBZ02 axial line scribing line figure, by port and starboard FR42# with
Axial line intersection point, which is refuted, on FR36# rib position marks as basis on location:
3, block installation positioning is carried out to Double gear box with segmentation axial line
Gear cage base is lifted into installation site, setting segmentation axial line on cabin inner bottom plating using total station, will as reference line
The ocean punching point of gear cage base is aligned with segmentation axial line.Confirm pedestal levelness and height, if need to cut surplus.Use whole station
Instrument sets FR42# rib bit line and determines gear-box front-rear position.The burned guide pad of pedestal left and right side, the burned cylinder bracket of front-rear position,
For adjusting pedestal front-rear position.Ensure that Double gear box pedestal meets 2.4 ° of shafting lateral slopes.
4, the assembly of Double gear box pedestal, welding process monitoring
It has been adjusted within the scope of precision controlling before the assembly of Double gear box pedestal, welding, pedestal is subjected to constraint tack welding
It connects, takes balanced welding in peripheral quadrangle, total station repetition measurement pedestal data are used after peripheral board welding equipment is good, it is overproof if any dimension data
Phenomenon stops being adjusted at once, and pending data continues welding equipment internal framework after being adjusted in place, and carries out again after the completion of electric welding primary detailed
Thin repetition measurement ensures that pedestal meets required precision.Data record is carried out simultaneously, the construction reference frame as the subsequent ship of offer.
5, Double gear box pedestal welding equipment overall process carries out tracking measurement data
It all arranges special messenger to carry out tracking measurement to the welding equipment process of pedestal in every morning, afternoon to proofread in time.
6, it resets and makees to zygonema and monitoring coordinate points after Double gear box pedestal segmentation coating
Another critical stage of the project is that be applied that will be segmented feeding after Double gear box pedestal and cabin segmentation welding equipment
Whole sand washing coating is carried out between entrucking, that requires secondary reset positioning states for the first time must be put in segmentation and pedestal.It is logical
It crosses and block entirety measurement data is collected, draws 100M.K to three insurance methods of zygonema and setting 3 D monitoring point to complete to apply
Reset work after dress.
Above-mentioned steps have the following beneficial effects:
1. later process is done in advance
The project implementation substantially increases the efficiency of hull construction, originally considers the positioning accuracy control of diclinic shafting gear cage base
The difficulty of system is larger, so just positioning Double gear box pedestal after waiting sterns cabin segment carrying, not only site work environment is poor,
And need to expend a large amount of working hour and go to complete base stand location welding equipment, in addition relevant stowed on deck segmentation can also be affected by it nothing
Method is carried in advance, can not shorten entire construction period.
2. precision controlling Whole plot
The Whole plot that precision controlling process has been reacted in the project implementation is carried out, and Double gear box pedestal is installed on block, i.e.,
Guarantee that 2.4 ° of shafting slopes meet block size, also ensures that its block carries and meet whole shafting requirement.
3. Promoting Standardized shipbuilding technology
The propulsion of the project may conform to the building technology Standardization Practice under present shipbuilding new model, the construction to similar type ship
Production standard is provided, it is horizontal to promote company's shipbuilding.
Although above-described embodiment makes specific descriptions to the present invention, come for those of ordinary skill in the art
It says, it is understood that can be modified within spirit and scope of the invention based on present disclosure not departing from
Or improve, these modification and improvement are all within spirit and scope of the invention.
