5000pctc lighting process for shafting of ro-ro ship

Abstract

The invention relates to a 5,000PCTC (pure car and truck carrier) shafting irradiation process and belongs to the technical field of ships. The 5,000PCTC (pure car and truck carrier) shafting irradiation process comprises the following steps: enabled light targets with crossed scribed lines to be arranged on a head base point and a tail base point, and enabling a sighting instrument to be located at the back of the tail base point; arranging eight-leg light target frames in an inner hole of a tail shaft pipe, enabling the front light target and the rear light target to be fixed on the eight-leg light target frames, and performing preliminary alignment according to the inner hole; correcting the standard of the sighting instrument according to the tail base point; performing operation repeatedly until the sighting instrument passes through the head base point and the tail base point; respectively adjusting the light target frames of the front light target and the rear light target in the tail shaft pipe to enable two light target centers to coincide with the head base point and the tail base point; checking centering conditions according to the well adjusted center positions of the front light target and the rear light target in the inner hole of the tail shaft pipe; adjusting the focus of the sighting instrument, and checking left-and-right centering conditions of a bearing block; hanging a counter weight, and checking left-and-right centering conditions of a base; measuring relative positions of the shafting center line and rudder center line; and check and correcting positions of a bow base point and a stern base point until the requirements are met.

Description

technical field [0001] The invention relates to a shafting lighting technology, in particular to a shafting lighting technology suitable for a 5000 PCTC ro-ro ship, and belongs to the technical field of ships. Background technique [0002] At present, many shipyards often have a series of problems such as jamming or unqualified test torque when installing the main engine and drive shaft, and have to rework. The phenomenon of scrapping is mainly due to the unreasonable setting of the centering process between the center of the stern tube and the center of the shafting, resulting in not being on the same center line, which is an urgent problem to be solved. Contents of the invention [0003] The purpose of the present invention is to provide 5000PCTC vehicle-roller ship shafting lighting technology. [0004] The invention aims to solve the problems of poor welding accuracy of the existing stern shaft frame, which affects the service life of the ship. [0005] For realizing...
