Installation method for base of steering engine

Abstract

The invention discloses an installation method for a base of a steering engine. The installation method mainly comprises the following steps that firework correction is carried out on a target segment; the base of the steering engine is pre-installed on the target segment, and loading of the target segment is carried out; and gaskets on the base of the steering engine are installed. A completely new method is adopted to achieve accuracy control of pre-assembly and loading of the section where the base of the steering engine is located, it is ensured that the deviation between the measured height value and the theoretical height value of a steering engine platform to a hull baseline is within the tolerance range, the installation accuracy of the base of the steering engine is ensured, height allowance does not need to be added to the base of the steering engine in advance, and cutting of the allowance of the base of the steering engine on the spot is not required; and since the base ofthe steering engine is pre-installed and welded in the segmentation stage, no later welding work exists, therefore oil paint of a ballast tank below the base of the steering engine cannot be damaged,requirements of the PSPC specification are fully met, materials are saved, a lot of manpower is saved, and the period of dock construction is shortened.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a method for installing a steering gear base. Background technique [0002] The conventional method of installing the steering gear base is as follows: [0003] Step 1. Position the steering gear base at the dock stage or slipway stage. [0004] Step 2. Measure the height of the plane on the base of the steering gear. [0005] Step 3. Cut the servo base according to the measured height. [0006] Step 4. Weld the steering gear base. [0007] Step 5. Sand and repaint the damaged part of the paint on the top of the ballast water tank at the lower tail. [0008] If the conventional method of installing the steering gear base is adopted, there will be the following deficiencies: [0009] First, it is necessary to add a height margin to the steering gear base in advance, which is used to adjust the height and level of the steering gear base during the installation process, w...

AI Technical Summary

Problems solved by technology

[0010] Second, it is necessary to cut the heightening margin of the steering gear base on site, which wastes a lot of manpower and docking cycle

[0011] Third, the paint on the ballast water tank under the steering gear base is damaged, which makes it difficult to meet the PSPC specification requirements
