Embodiment Construction

[0028] 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.

[0029] For ease of description, in this embodiment, the left side of segment 1 is the stern of the ship, and the right side of segment 1 is the bow of the ship; the left end of the fairing 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).

[0030] Such as Figure 1~4 As shown, the segment 1 is supported upside down on the ground by the segme...

Abstract

The invention discloses a positioning method of a stream guidance cover on a segmentation. An installing axis line is erected below a base level by a rope after the base level is confirmed. The perpendicular distance of an opposite base level at two ends of the installing axis line is confirmed. A gap of a center line of a relative segmentation of the installing axis line in the horizontal direction is confirmed. A position of the stream guidance cover sleeved outside the installing axis line corresponding to the installing axis line is adjusted. The position of the stream guidance cover is adjusted, thus a middle axis line of the stream guidance cover coincides with the installing axis line. An end surface supporting used for supporting the stream guidance cover is arranged on the stem end side of the stream guidance cover. By means of the positioning method of the stream guidance cover on the segmentation, the intangible middle axis line is changed to be tangible. Rigidity of the installing axis line is guaranteed. The stream guidance cover is installed before the segmentation is closed, thus the positioning operation of the stream guidance cover is moved from the front of a dock to the segmentation manufacturing stage. The positioning difficulty of the stream guidance cover in the dock is reduced. The dock period is shortened. Due to the fact that a segmentation shaped grid and the segmentation are relatively fixed, the middle axis line of the segmentation does not move partially. Precision and accuracy of the installation are guaranteed. Welding difficulty is reduced.

Description

technical field [0001] The invention relates to a method for positioning a shroud on a segment. Background technique [0002] In the current shipbuilding industry, for the installation of the shroud, it is basically taken to close up the sections in the dock, and then install it facing the sky in the dock. This method has relatively high requirements for the tooling for positioning the dome in the dock, and the positioning and welding are relatively difficult, and the docking period will be longer. The positioning method of the shroud 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 shroud is installed from bottom to top in the dock, it will cause a lot of upward welding work in the dock. ...
