Problems solved by technology

[0002] For surface ships that have been in service for a long time, due to various factors such as structural deformation, the shafting centerline may change. When the ship is repaired, there is no reference point to directly obtain the shafting centerline

Embodiment Construction

[0028] In order to further explain the technical means and effects that the present invention takes to achieve the intended purpose of the invention, below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation and work of a method for repairing the shafting system of a surface ship based on the axis method proposed by the present invention The principle is explained in detail.

[0029] Such as figure 1 As shown, the overall design idea of ​​a method for repairing the shafting of a surface ship by the axis method provided by the embodiment of the present invention includes:

[0030] S1. Set the lighting point on the hull.

[0031] S2. Adjust the position of the light point so that the light point and at least two points in the center points of the head and tail of the multiple bearings at the stern of the hull are on the same straight line. At this time, the light point is a relative reference point;

[0032] S3. Measure the rela...

Abstract

The invention relates to the technical field of water surface ship shafting center line correction, and particularly discloses a water surface ship axis normal shafting repairing method which comprises the following steps: arranging irradiation points on a ship body; adjusting the position of the irradiation point, so that the irradiation point and at least two central points in the head and tailcentral points of the plurality of bearings at the tail of the ship body are positioned on the same straight line, and the irradiation point is a relative reference point; measuring relative deviationbetween head and tail central points of a plurality of bearings at the tail of the hull and the relative reference point; fitting an axis through the deviation value, and enabling the deviation between the axis and the head and tail center points of a plurality of bearings at the tail of the ship body to be within the technical requirement range allowed by shafting centering, namely, the axis canserve as a reference center line for ship body shafting repairing. The method is easy and convenient to apply and high in operability, the center line of the ship shafting can be rapidly determined,and a reliable shafting reference is provided for long-term service ship shafting repairing.

Description

technical field [0001] The invention relates to the technical field of correction of the shafting centerline of a water surface ship. Background technique [0002] For surface ships that have been in service for a long time, due to various factors such as structural deformation, the shafting centerline may change. When the ship is repaired, there is no reference point to directly obtain the shafting centerline. Contents of the invention [0003] The purpose of the present invention is to address the above problems, to provide a method for repairing the shafting of a surface ship using the axis method, which can move the lighting point to the relative reference point by setting the lighting point and using the center points of the head and tail of multiple bearings in the stern as an auxiliary. The relative deviation between the reference point and the center of the fore and aft of the multiple bearings at the stern of the hull is fitted to fit the required axis as the refe...
