Mounting positioning method for ship hawse pipe

Abstract

The invention provides a mounting positioning method for a ship hawse pipe. The mounting positioning method for the ship hawse pipe is used for the mounting the hawse pipe between decks and external plates and comprises the following steps that S1, a positioning base point required by mounting is determined; S2, positioning is conducted on the position of a second intersection point of the center line of the hawse pipe and the external plates, and penetrating holes are formed in a first intersection point and the second intersection point; S3, the hawse pipe is hoisted to the penetrating holes and initial positioning is conducted; S4, subsection control datum points serve as datum, real data of upper end center point of the upper end of the hawse pipe and lower end center point of the lower end of the hawse pipe are measured correspondingly, vector error of the upper end center point and the lower end point is determined according to vector relation of the first intersection point and the second intersection point, and adjusting distances of the hawse pipe in all directions are calculated; and S5, a mounting position of the hawse pipe is adjusted according to the adjusting distances of the hawse pipe in all directions, and positioning of the hawse pipe is finished. Precise and quick mounting positioning of the hawse pipe is achieved, and mounting efficiency of the hawse pipe is improved.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a method for installing and locating a ship anchor chain cylinder. Background technique [0002] As an important part of ship mooring, the bow mooring structure has a direct impact on the safety of ship mooring due to its installation quality. If the installation of the mooring structure fails to meet the design requirements, problems such as the anchor fluke hitting the hull and the anchor fluke not being able to be lowered smoothly may easily occur during the anchor fluke fixing and anchoring stages. As one of the important components of the anchorage structure, the anchor chain barrel is also the first step in the quality control of the anchorage installation. Its installation and positioning accuracy directly determines whether the other components of the anchorage structure and the overall accuracy of the anchorage system can meet the design requirements.
