Embodiment Construction

[0027] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0028] For ease of description, in this embodiment, the left side of section 1 is the stern of the ship, and the right side of section 1 is the bow of the ship; the left end of the stern tube support seat 5 is the stern, and the right end is the bow. And the line connecting the bow and stern is defined as the X-axis direction (in figure 1 The middle is the horizontal direction), and the Y-axis direction is positioned in the direction perpendicular to the X-axis in the horizontal plane ( figure 1 in the vertical paper direction), figure 1 The upward direction of the outer surface of the middle segment 1 is the Z-axis direction ( figure 1 The middle is the upward direction along the paper surface).

[0029] Such as Figure 1~4 As shown, the segment 1 is supported upside down on the gro...

Abstract

The invention discloses a method for locating a tail pipe supporting seat in a subsection. The method is characterized by comprising the following steps of firstly determining the distance between an axis where the tail pipe supporting seat is located and a center line of the subsection in a horizontal direction; then determining a reference surface and the vertical distance from a bow end center and a stern end center which are positioned on the axis where the tail pipe supporting seat is located to the reference surface; forming an installation axis of the tail pipe supporting set by connecting the bow end center and the stern end center by a rope; carrying out fine tuning on the position of the tail pipe supporting seat, and enabling a central axis of the tail pipe supporting seat to be coincided with the installation axis; and connecting the tail pipe supporting seat with a beauty stand. According to the method disclosed by the invention, the central axis which is invisible is concretized, the rigidity of the installation axis is ensured, the tail pipe supporting seat is installed before the subsection is closed, the location operation of the tail pipe supporting seat is changed into a subsection manufacturing section from a dock, the difficulty of carrying out the location of the tail pipe supporting seat in the dock is reduced, and the dockage period is shortened; and a subsection jig frame is relatively fixed with the subsection, thus the central axis of the subsection cannot offset, the precision and the accuracy of installation are ensured, and the welding difficulty is reduced.

Description

technical field [0001] The invention relates to a positioning method of a tail pipe support seat on a segment. Background technique [0002] In the current shipbuilding industry, for the installation of the stern tube support seat, basically take the method of closing up in the dock in sections, and then install it in the sky in the dock. This method has relatively high requirements for the tooling for positioning the stern tube support seat in the dock, and the positioning and welding are relatively difficult, and the docking period will be longer at the same time. The positioning method of the stern tube support seat on the segment can greatly reduce the difficulty of installation, construction and welding in the dock, bring great economic benefits, and greatly shorten the docking period. [0003] The traditional positioning method is to install it in the sky after the sections are closed in the dock, which causes many problems: [0004] 1. If the stern tube support seat...
