Embodiment Construction

[0059] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0060] Such as Figure 7 and Figure 8 Shown is a general layout diagram of the tail of a ship in the prior art. The present invention describes the process of improving and designing the tail structure in combination with the general layout of the tail of the ship in the prior art. Such as Figure 7 As shown, the tail structure includes a tail peak tank 21, a tail shaft cooling water tank 22, a propeller 23 and a rudder arm 14, the tail peak tank 21 is arranged on the upper end of the tail shaft cooling water tank 22, and the propeller 23 is connected to the tail shaft cooling water One side of the cabin 22 and one side of the aft peak tank 21 are provided with a rudder arm 14 connected with a rudder; Such as Figure 8 As shown, it is a schematic diagram of the mid-longitudinal section of the stern structure, including th...

Abstract

The invention discloses a ship stern column, the stern column includes an outer plate, a shaft hub and a round steel, one end of the shaft hub protrudes from the outer plate, and is used to connect the propeller of the ship; the round steel is along the Extending along the outline of the outer plate; the outer plate includes a first outer plate and a second outer plate, the end faces of the first outer plate and the end faces of the second outer plate are respectively connected to the round steel The outer wall is connected, and the diameter of the round steel is larger than the wall thickness of the first outer plate or the second outer plate. With the present invention, the connection position of the tail end of the outer plate is moved forward, that is, the connection position of the original middle longitudinal section is moved to a position tangent to the outer edge of the round steel, which increases the operating space inside the hull and effectively improves the construction efficiency. craftsmanship. In addition, round steel replaces a part of the outer plate, correspondingly, the size of the outer plate is reduced, thus reducing the processing difficulty of the outer plate, especially the outer plate with two-way curvature at the tail.

Description

technical field [0001] The invention relates to a ship stern post. Background technique [0002] The stern post is the member at the rear end of the hull used to connect the outer plates and keels on both sides, including propeller post 10, rudder post 11 and stern frame bottom bone 12, etc.; moment. The type of stern post is related to the type of rudder and the number of propellers. For conventional ships, such as oil tankers and bulk carriers, usually only one propeller is installed; for ships with special requirements for maneuverability, only two or more propellers are installed, such as engineering ships and military ships. Therefore, conventional The type of stern post on a ship is only related to the type of rudder. The rudders used in some of the existing ships are multi-supported rudders. The stern post structure on this ship not only has a propeller post, but also has a rudder post and a stern frame bottom bone. figure 1 shown. The rudders used on some ships ...
