Problems solved by technology

[0004] First, it is necessary to bore the rudder system, which wastes a lot of manpower and docking cycle
[0005] Second, it is difficult to consider the sinking of the general section where the rudder stock tube is located during loading and the welding shrinkage of the general section where the shafting is located, so it is difficult to meet the high-precision technical requirements for rudder propeller matching

Embodiment Construction

[0041] like Figure 1-10 As shown, the installation method of the rudder-propeller integrated propulsion system in this embodiment includes the following steps, S1, pre-installation of the rudder cylinder in sections, S2, prediction of the deformation of the stern general assembly, S3, and the stern general assembly , S4, shafting, propeller and rudder blade installation;

[0042] The segmental pre-installation of the S1 rudder stock includes the following steps:

[0043] ① Level the section 1 where the rudder stock tube is located, adjust the level of the steering gear platform 2 and the base plate 3 in turn,

[0044] ②Find out the center line L1 of the theoretical rudder system on the section 1 where the rudder stock barrel is located, and project the center line L1 of the theoretical rudder system onto the horizontal baseline L2,

[0045] ③ After hoisting the rudder stock tube 4 in place, use a total station to measure the level of the steering gear platform,

[0046] ④ ...

Abstract

The invention discloses an installation method of a steering oar integrated propelling system. The method includes the following steps that S1, a rudder trunk section is pre-assembled; S2, stern general assembly carrying deformation is predicted; S3, a stern is generally assembled and carried; and S4, a shaft system, a propeller and rudder blades are installed. The method includes the specific steps that the section where a rudder trunk is located is leveled, a theoretical rudder system center line L1 on the section where the rudder trunk is located is found, the level of a steering engine platform is measured through a total station, the rudder trunk and a hull structure are welded, according to the prediction of general assembly carrying welding shrinkage deformation and stern sinking finite element analysis, reverse deformation is set in a stern block carrying stage, then the stern is generally assembled and carried, and finally, the shaft system, the propeller and the rudder bladesare installed. The brand-new method is adopted for meeting the requirement for the shaft system and rudder system installation accuracy, the one-time installation success rate is increased, the steering oar matching high-accuracy technical requirement can be met, and a period of a dock is shortened.

Description

technical field [0001] The invention belongs to the technical field of ship building, and in particular relates to an installation method of a rudder-propeller integrated propulsion system. Background technique [0002] The highly efficient and energy-saving rudder-propeller integrated propulsion system consists of a fully suspended rudder with a rudder ball and a propeller with a concave spherical spinner cap. Because this type of system can effectively improve the propulsion efficiency of the ship and improve the operating efficiency of the ship owner, it has gradually become a widely used system. However, the installation accuracy requirements of this type of system are particularly high. The complex and high-precision installation requirements make the installation success rate low, and the installation procedure is complicated and the cycle is long. [0003] If the traditional installation method of the existing shaft and rudder system is adopted, there will be the fol...
