Installation method of bow transverse thrust unit

Abstract

The invention relates to an installation method of a bow transverse thrust unit and belongs to the technical field of ships. The installation method comprises the following steps of pre-installing a barrel on the stroke side and the starboard at the bottom of a ship body, checking and correcting the circular degree of the barrel, and marking a center line of the barrel; measuring the height between the center line of the barrel and a basic line (BL); checking and measuring parallelism and distance between the center line of the barrel and a motor base, and ensuring the center line of the barrel to be parallel to the upper surface of the base; erecting temporary supports at two ends in the barrel in order to ensure rigidness of the barrel; adjusting the distance between the center line of the barrel and a base level with a flange plane (the upper surface) of the motor base of the barrel serving as the base level; checking levelness of the flange plane of the motor base, and ensuring a positioning error to be within + / -2mm; and after correct positioning, primarily performing spot welding on the base and the barrel to achieve fixation, and performing welding on the barrel through a section symmetric welding method to reduce various deformations caused by welding. The bow transverse thrust unit installed through the method is high in installation accuracy, small in power loss and large in output power.

Description

technical field [0001] The invention relates to a method for installing a bow thruster, in particular to a method for installing a bow thruster for a container ship, and belongs to the technical field of ships. Background technique [0002] In recent years, with the rapid development of the shipping industry, the performance requirements for ships are getting higher and higher, especially for large ships such as container ships, the cost of which is basically hundreds of millions. It is estimated that collisions and tentacles are the most frequent accidents. The basic reason is that the ship turns too slowly. The fast turn of the ship has high requirements for the installation of the bow thruster. Large, and the loss of equipment is also large. At present, a mature installation process is urgently needed to solve this problem. Contents of the invention [0003] The purpose of the present invention is to provide a bow thruster installation method. [0004] The problem to ...
