Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology and processes, and in particular to a method for assembling ship sections. Background Technology

[0002] In the construction of ship sections such as the bottom section of the main hull, the upper structure and the superstructure, the assembly, positioning, inspection and adjustment of various components, especially the internal longitudinal and transverse bulkheads and outer plates of the section, including the bow and stern end plates, are the most basic and important links in the construction of sections.

[0003] At present, all of the above-mentioned tasks require the use of various tools such as plumb bobs, spirit levels, and even the assistance of guy wires. They are carried out by multiple people, and the operation methods are relatively backward, the process is cumbersome, and the waiting time for the plumb bob to stop is relatively long. Moreover, the plumb bob is greatly affected by the environment. Therefore, the overall work efficiency is low.

[0004] Therefore, a method for assembling ship sections is needed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a method for assembling ship sections, which simplifies the assembly process, saves time and effort, and improves the overall assembly efficiency of the sections.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The method for assembling ship sections includes the following steps:

[0008] S1. Assemble the outer panel assembly, longitudinal wall panel assembly, and transverse wall panel assembly. Mark the first rib inspection line on the outer panel assembly and build a workbench.

[0009] S2. Mark segmented cross reference lines on the workbench surface, and measure and mark the second rib inspection line, the first installation position line of the longitudinal wall panel assembly, and the second installation position line of the transverse wall panel assembly on the workbench surface based on the cross reference lines.

[0010] S3. Hoist the longitudinal wall panel assembly to the first installation position line, adjust the longitudinal wall panel in the longitudinal wall panel assembly to be in a vertical state, position and support the longitudinal wall panel assembly, hoist the transverse wall panel assembly to the second installation position line, adjust the transverse wall panel in the transverse wall panel assembly to be in a vertical state, position and support the transverse wall panel assembly;

[0011] S4. Hoist the outer panel assembly onto the workbench for adjustment and installation. The second rib inspection line on the workbench is consistent with the marked first rib inspection line. Assemble the transverse wall panel assembly on the outer panel assembly and adjust the half-width of the open part of the outer panel assembly according to the design requirements to support and position the outer panel assembly.

[0012] In some embodiments, in step S1, the outer panel assembly, the longitudinal wall panel assembly, and the transverse wall panel assembly that have been welded and assembled are straightened.

[0013] In some embodiments, in step S1, the upper tire plate is assembled and welded on the segmented tire frame to form the workbench.

[0014] In some embodiments, the first rib inspection line is marked on the outer panel assembly using punch marks and paint.

[0015] In some embodiments, in step S2, a laser theodolite is used to project the segmented crosshair reference lines onto the platform.

[0016] In some embodiments, in step S3, a first parallel line is drawn on the table surface according to the offset of the first installation position line by a set distance. The first parallel line is parallel to the first installation position line and is located on the non-structural side of the longitudinal wall panel assembly. When the longitudinal wall panel is parallel to the vertical plane where the first parallel line is located, the longitudinal wall panel is in a vertical state.

[0017] In some embodiments, in step S3, a second parallel line is drawn on the table surface according to the offset of the second installation position line by a set distance. The second parallel line is parallel to the second installation position line and is located on the non-structural side of the horizontal wall panel assembly. When the horizontal wall panel is parallel to the vertical plane where the second parallel line is located, the horizontal wall panel is in a vertical state.

[0018] In some embodiments, a projection device is used to simulate a vertical plane by aligning it with the first parallel line or the second parallel line.

[0019] In some embodiments, in step S4, the second rib inspection line is extended and marked onto the ground where the segment is located, and the first rib inspection line is adjusted to be consistent with the second rib inspection line to adjust and assemble the position of the outer panel assembly.

[0020] In some embodiments, in step S4, the outer panel mounting position line of the outer panel assembly is consistent with the height of the deck or platform.

[0021] The beneficial effects of this invention are:

[0022] This invention provides a method for assembling ship sections, comprising assembling outer plate assemblies, longitudinal bulkhead assemblies, and transverse bulkhead assemblies. First rib inspection lines are marked on the outer plate assemblies, and a workbench is constructed. Segmentation crosshairs are marked on the workbench surface. Using these crosshairs as a standard, second rib inspection lines, first installation position lines for the longitudinal bulkhead assemblies, and second installation position lines for the transverse bulkhead assemblies are measured and marked on the workbench surface. The longitudinal bulkhead assemblies are hoisted to the first installation position line, and the longitudinal bulkheads within them are adjusted to a vertical position for positioning and support. The transverse bulkhead assemblies are hoisted to the second installation position line, and the transverse bulkheads within them are adjusted to a vertical position for positioning and support. The outer plate assemblies are then hoisted onto the workbench for adjustment and installation. The second rib inspection line on the workbench aligns with the marked first rib inspection line. The transverse bulkhead assemblies are then assembled onto the outer plate assemblies, and the half-width of the open portion of the outer plate assemblies is adjusted according to design requirements for support and positioning. By setting crosshairs to determine the first and second installation position lines, the positioning of the transverse and longitudinal wall panel assemblies is facilitated. By marking the first rib inspection line on the outer panel assembly, the first and second rib inspection lines are aligned during the outer panel assembly installation process for positioning. This method simplifies the assembly process, saves time and effort, and improves the overall assembly efficiency of the segments. Attached Figure Description

[0032] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0033] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0034] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0035] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0036] In the process of ship segment construction, in order to simplify the assembly process, save time and labor, and improve the overall assembly efficiency of the segments, such as... Figures 1-5 As shown, this invention provides a method for assembling ship sections. The method for assembling ship sections includes the following steps:

[0037] S1. Assemble the outer panel assembly 6, longitudinal wall panel assembly and transverse wall panel assembly, mark the first rib inspection line 61 on the outer panel assembly 6, and build a workbench.

[0038] S2. Mark segmented cross reference lines on the workbench surface. Using the cross reference lines as the standard, measure and mark the second rib inspection line, the first installation position line 2 of the longitudinal wall panel assembly, and the second installation position line 3 of the transverse wall panel assembly on the workbench surface.

[0039] S3. Hoist the longitudinal wall panel assembly to the first installation position line 2, adjust the longitudinal wall panel 4 in the longitudinal wall panel assembly to be in a vertical state, position and support the longitudinal wall panel assembly, hoist the transverse wall panel assembly to the second installation position line 3, adjust the transverse wall panel 5 in the transverse wall panel assembly to be in a vertical state, position and support the transverse wall panel assembly.

[0040] S4. Hoist the outer panel assembly 6 onto the workbench for adjustment and installation. The second rib inspection line on the workbench should be aligned with the marked first rib inspection line 61. Assemble the transverse wall panel assembly on the outer panel assembly 6 and adjust the half-width of the opening of the outer panel assembly 6 according to the design requirements. Support and position the outer panel assembly 6.

[0041] By setting a crosshair reference line to determine the second rib inspection line, the first installation position line 2, and the second installation position line 3, the positioning of the transverse and longitudinal wall panel assemblies is facilitated. By marking the first rib inspection line 61 on the outer panel assembly 6, the first rib inspection line 61 aligns with the second rib inspection line during the installation of the outer panel assembly 6 for positioning. Using this method simplifies the assembly process, saves time and effort, and improves the overall assembly efficiency of the segments.

[0042] In some embodiments, in step S1, the outer panel assembly 6, the longitudinal wall panel assembly, and the transverse wall panel assembly that have been welded and assembled are straightened. Through straightening, it can be ensured that the outer panel assembly 6, the longitudinal wall panel assembly, and the transverse wall panel assembly meet the design requirements, and the accuracy of positioning and assembly is guaranteed in the subsequent positioning and assembly process.

[0043] In some embodiments, in step S1, the upper plate 11 is assembled and welded on the segmented jig 1 to form a workbench. The workbench is designed according to the segmented structure to facilitate the subsequent positioning and assembly of the outer panel assembly 6, the longitudinal wall panel assembly, and the transverse wall panel assembly.

[0044] In some embodiments, a first rib inspection line 61 is marked on the outer panel assembly 6 using a punch mark and paint. By using a punch mark and paint marking, it is easier for construction personnel to observe during the subsequent positioning of the outer panel assembly 6, thereby ensuring the accuracy of construction.

[0045] In some embodiments, in step S2, a laser theodolite is used to mark segmented crosshair reference lines on the table. Using a laser theodolite facilitates rapid marking of segmented crosshair reference lines, eliminating the need for the installation of traditional wire drawing frames, saving on materials and wire, and reducing the management of tooling fixtures. Furthermore, the laser theodolite is unaffected by the external environment, facilitating subsequent marking and positioning assembly operations.

[0046] In some embodiments, in step S3, a first parallel line is drawn on the table surface according to a predetermined offset distance from the first installation position line 2. The first parallel line is parallel to the first installation position line 2 and is located on the non-structural side of the longitudinal wall panel assembly. When the longitudinal wall panel 4 is parallel to the vertical plane containing the first parallel line, the longitudinal wall panel 4 is in a vertical state. In this way, the verticality of the longitudinal wall panel 4 can be quickly adjusted to ensure that the longitudinal wall panel 4 is in a vertical state.

[0047] In some embodiments, in step S3, a second parallel line is drawn on the table surface according to the offset of the second installation position line 3 by a set distance. The second parallel line is parallel to the second installation position line 3 and is located on the non-structural side of the horizontal wall panel assembly. When the horizontal wall panel 5 is parallel to the vertical plane containing the second parallel line, the horizontal wall panel 5 is in a vertical state. In this way, the verticality of the horizontal wall panel 5 can be quickly adjusted to ensure that the horizontal wall panel 5 is in a vertical state.

[0048] In some embodiments, a line projector is aligned with a first parallel line or a second parallel line to simulate a vertical plane. Because the line projector has the characteristic of continuous line projection, it can effectively simulate a vertical plane, and it is unaffected by the external environment, making it convenient to detect and adjust the verticality of the longitudinal wall panel 4 and the transverse wall panel 5. To facilitate the installation of the line projector, a simple bracket can be made to fix it in place.

[0049] In some embodiments, in step S4, the second rib inspection line is extended and marked onto the ground where the segment is located, and the first rib inspection line 61 is aligned with the second rib inspection line to adjust and position the outer panel assembly 6. This method avoids the assembly and positioning of the outer panel assembly 6 being affected by the internal longitudinal wall panel 4 and transverse wall panel 5 or limited space, facilitating rapid positioning of the outer panel assembly 6.

[0050] In some embodiments, in step S4, the mounting position line of the outer panel assembly 6 is aligned with the height of the deck or platform. This limitation allows for the determination of the mounting height position of the outer panel.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
