The invention discloses a method for illuminating the shafting of a ship. The method mainly includes the steps of: first finding two points on the theoretical centerline of the shafting, and the two points passed by the optical collimator are the actual centerline of the shafting; Find two light targets in the middle of the entire shaft system as the new bow and stern reference points after the shaft system is segmented, and use the new bow and stern reference points to illuminate the new shaft segment respectively. Compared with the prior art, the method has the beneficial effect that it can solve the problem of low lighting accuracy of shafting due to defects of lighting instruments in the construction of ships with long shaftings. The lighting time of the shafting is greatly shortened, and the influence of the hull deformation on the lighting accuracy of the shafting is minimized.
Description
A lighting method for ship shafting Technical field [0001] The present invention relates to the shipbuilding industry, in particular to a method for shafting lighting in the shipbuilding process. Background technique The shafting of a ship is one of the key processes to ensure the sailing performance of a ship. heart line. Existing general ship shafting is about 40 meters from the center of the propeller to the output flange of the gearbox, and the stern tube Shorter, all the paddle shafts and part of the stern shaft are fixed on the large and small shaft brackets (as shown in Figure 1) at the stern of the ship. inside the hull A number of intermediate bearings are evenly distributed on the inside to carry the intermediate shaft, and then the main part of the gearbox. The shafting illumination of such ships is average Firstly, the bow and stern reference points are determined, that is, the propeller center is used as the stern reference point, and a certain point o...
