Description

Technical Field

[0001] This invention relates to the technical field of shipbuilding, and in particular to a method for installing column bases in the sectioning stage of a container ship and the container ship itself. Background Technology

[0002] In the core stage of container ship construction, the precise installation of deck pillars is crucial to ensuring the structural strength of the ship and the efficient and safe stacking of containers. As the core transmission path for container stacking loads, the welding quality of the base of the pillars to the deck structure and the accuracy of their relative position directly determine the operational safety and service life of the ship.

[0003] Current container ship deck column installation technology suffers from significant bottlenecks in terms of precision control and installation efficiency. It heavily relies on manual experience and the process is uncontrollable, becoming a major factor restricting shipbuilding quality and schedule. There is an urgent need to introduce high-precision new technologies to achieve accurate positioning and installation of the column columns, thus overcoming this long-standing engineering challenge. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects in the prior art where various factors cause deviations in the installation accuracy of the box column, requiring repeated corrections, and to provide a box column installation method for the sectioning stage of a container ship and a container ship.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A method for installing column anchors during the sectionalization stage of a container ship, wherein the deck of the container ship is placed vertically during the sectionalization stage, and the method includes the following steps:

[0007] S1: Pre-process the bevel at the bottom of the box column;

[0008] Pre-positioning of the box column installation location on the deck;

[0009] S2: Move the box column to the predetermined position on the deck;

[0010] S3: Secure the box column to the deck.

[0011] In this solution, the container columns are installed during the sectional construction phase of the container ship. Side-mounted construction facilitates installation. Pre-processing the bevel at the bottom of the column offsets losses during welding, preventing the column from warping horizontally during welding. Anti-deformation welding eliminates the need for secondary corrections, reducing manual adjustment costs. Furthermore, pre-positioning on the deck before installation effectively improves the accuracy of the column installation, making subsequent installation more efficient and convenient. After installation, the column is firmly connected to the deck, resulting in a long service life.

[0012] Preferably, before the step of pre-positioning the box column installation location on the deck, the method further includes the step of:

[0013] S1.1: Control the flatness of the deck so that the flatness of the deck does not exceed 4mm.

[0014] In this plan, the flatness of the deck is adjusted before the box columns are installed to avoid subsequent welding work being impossible due to uneven deck surface, and to prevent bulging and other problems from easily occurring after the box columns are installed, which would reduce the service life of the box columns. Pre-leveling helps to improve the accuracy of the operation and extend the service life of the box columns.

[0015] Preferably, the step of pre-positioning the box column installation location on the deck further includes the step of:

[0016] S1.2: Draw the structural lines of the box column on the deck according to the installation drawings of the box column;

[0017] S1.3: A temporary support device is installed below the structural line.

[0018] In this scheme, pre-positioning based on the installation drawings ensures that the subsequent installation of the box columns meets design requirements. Furthermore, drawing structural lines on the deck facilitates practicality and ensures accurate positioning without damaging the deck or box column structure; these lines can be erased after installation. Temporary support devices are installed below the structural lines, allowing the box columns to be erected on them during subsequent operations, preventing displacement and providing a certain degree of support.

[0019] Preferably, at least two temporary support devices are provided below the structural line.

[0020] In this scheme, setting up two temporary support devices provides better stability, making it less prone to shaking or movement during operation. This avoids increased construction difficulty due to insufficient support and also prevents a reduction in the accuracy of the box column installation.

[0021] Preferably, step S2 further includes:

[0022] S2.1: Hoist the box column onto the temporary support device and align the bottom of the box column with the structural line.

[0023] In this solution, cranes and other tools are used to lift the box columns onto the temporary support device, which facilitates subsequent adjustments to the box columns. The temporary support device provides good support and is less prone to displacement than working directly during the lifting stage, thus reducing the accuracy of the box column installation.

[0024] Preferably, step S3 further includes:

[0025] S3.1: Measure the levelness of the box column and make adjustments accordingly;

[0026] S3.2: Fix the bottom of the box column to the deck by spot welding;

[0027] S3.3: Remove the temporary support device;

[0028] S3.4: Weld the box column to the deck.

[0029] In this plan, the horizontal level of the box column panel needs to be measured to ensure that the box column is installed horizontally and to avoid affecting normal use after installation. After the level is adjusted, the bottom of the box column is spot welded to fix it to the deck and prevent displacement. After the temporary support is removed, the box column is welded to make the connection between the box column and the deck more secure.

[0030] Preferably, the bevel is a single-sided bevel.

[0031] In this design, the bottom of the box column needs to be welded to the deck. The single-sided bevel design makes the operation more convenient. The single-sided bevel, with its pre-reserved slope, allows the electric arc to penetrate deep into the root during welding, ensuring the quality of the weld. At the same time, the prefabrication of the single-sided bevel is simpler and faster, reducing production costs.

[0032] Preferably, the relative height difference between the two sides of the bevel is 5-8 mm.

[0033] In this design, the box column will tilt horizontally during the welding process, so a downward counter-deformation of 5-8mm is applied to the box column to offset the wear and tear during the welding process.

[0034] A container ship includes a plurality of said column bases and a body, wherein the column bases are fixed to the body by a column base installation method as described in any of the above embodiments.

[0035] In this solution, container ships need to install multiple column supports. The column support installation method is simple to operate. By adding anti-deformation measures to offset the wear and tear during the welding process, the accuracy of column support installation is improved, and manual correction costs are saved.

[0036] Preferably, the installation positions of the multiple column pillars are adapted to the dimensions of the container.

[0037] In this solution, the above-mentioned setup ensures that the installation of the column can be compatible with the containers subsequently loaded onto the ship, avoiding situations where the column cannot be properly used after installation, thus avoiding waste of the column.

[0038] The positive and progressive effects of this invention are as follows: The pre-processed bevel at the bottom of the box column offsets the wear and tear during welding, preventing the box column from tilting upwards during welding. This anti-deformation welding method avoids secondary corrections and reduces manual correction costs. Furthermore, pre-positioning on the deck before installation effectively improves the accuracy of the box column installation, making the subsequent installation process more efficient and convenient. After installation, the box column is firmly connected to the deck, resulting in a long service life. Attached Figure Description

[0049] Container ship 5 Detailed Implementation

[0050] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0051] In this embodiment, as Figures 1-5 As shown, a method for installing column 1 in the sectioning stage of a container ship is provided. During the sectioning stage, the deck 4 of the container ship 5 is placed vertically, and the method for installing column 1 includes the following steps:

[0052] S1: Pre-process the bevel 2 at the bottom of the box column 1;

[0053] Pre-positioning of the installation location of the box column 1 on deck 4;

[0054] S2: Move column 1 to the predetermined position on deck 4;

[0055] S3: Fix the box column 1 to the deck 4.

[0056] The installation of the column 1 is carried out during the 5th section of the container ship. It can be constructed laterally, facilitating construction. Pre-processing the bevel 2 at the bottom of column 1 offsets the wear and tear during welding, preventing the column 1 from warping horizontally during welding. This anti-deformation welding eliminates the need for secondary corrections, reducing manual adjustment costs. Furthermore, pre-positioning on deck 4 before installation effectively improves the accuracy of column 1 installation, making subsequent installation more efficient and convenient. After installation, column 1 is firmly connected to deck 4, resulting in a long service life.

[0057] Specifically, in this embodiment, the pre-processing of the bevel 2 at the bottom of the box column 1 and the pre-positioning of the box column 1 on the deck 4 are two independent steps, both belonging to the pre-installation equipment stage. There is no specific order restriction between the two, and the order can be selected according to the site conditions.

[0058] Furthermore, before the step of pre-positioning the installation location of the box column 1 on deck 4, the following step is also included:

[0059] S1.1: Control the flatness of deck 4 so that the flatness of deck 4 does not exceed 4mm.

[0060] Before installing the box column 1, the flatness of the deck 4 should be adjusted to avoid the subsequent welding work being unable to be carried out due to the unevenness of the deck 4 surface. Also, the box column 1 is prone to bulging after installation, which will reduce the service life of the box column 1. Leveling in advance helps to improve the accuracy of operation and extend the service life of the box column 1.

[0061] Specifically, in this embodiment, the recessed area of ​​the deck 4 is heated by a spray gun to expand the recessed area, thereby improving the flatness of the deck 4. In other embodiments, other methods may also be used, such as laying materials to fill the recessed area, or pressing the protruding area with a pressure device, as long as the surface of the deck 4 is flat and it does not affect the installation of the box column 1.

[0062] In this embodiment, as Figure 2 As shown, the steps include: pre-positioning the installation location of the box column 1 on deck 4, and further steps include:

[0063] S1.2: Draw the structural lines of box column 1 on deck 4 according to the installation drawings of box column 1;

[0064] S1.3: Install temporary support device 3 below the structural line.

[0065] Pre-positioning according to the installation drawings ensures that the subsequent installation of the box column 1 meets the design requirements. Furthermore, drawing structural lines on deck 4 is convenient, practical, and accurate, without damaging the structure of deck 4 or box column 1, and can be erased after installation. Temporary support devices 3 are installed below the structural lines. During subsequent operations, box column 1 is supported on these temporary support devices, preventing displacement and providing a certain degree of support.

[0066] Specifically, in this embodiment, the box column 1 is a type of iron outfitting component. It is positioned and installed according to a pre-designed iron outfitting component installation drawing to avoid discrepancies between the actual installation and the drawing, which could lead to subsequent unusability, requiring adjustments, increasing labor costs, and damaging the structure of the deck 4 and box column 1, thus affecting its service life. The temporary support structure in this embodiment is a temporary jig, constructed from multiple hollow iron frames matching the dimensions of the box column 1. This facilitates production, allows for flexible movement, and can be recycled after use, preventing resource waste. In other embodiments, the temporary support device 3 can also be constructed using other components, only needing to provide support for the box column 1.

[0067] Furthermore, such as Figure 4 As shown, at least two temporary support devices 3 should be installed below the structural line. Installing two temporary support devices 3 provides better stability, reduces the likelihood of shaking or movement during operation, avoids increased construction difficulty due to insufficient support, and prevents a decrease in the installation accuracy of the box column 1.

[0068] In this embodiment, step S2 further includes:

[0069] S2.1: Hoist the box column 1 onto the temporary support device 3 and align the bottom of the box column 1 with the structural line.

[0070] Using cranes and other tools, the box column 1 is hoisted onto the temporary support device 3, facilitating subsequent adjustments to the box column 1. The temporary support device 3 provides better support and, compared to working directly during the hoisting stage, is less prone to displacement, thus reducing the installation accuracy of the box column 1. In other embodiments, other tools such as trolleys can also be used to move the box column 1; adjustments can be made according to the on-site equipment without specific limitations.

[0071] In this embodiment, as Figure 3 As shown, step S3 further includes:

[0072] S3.1: Measure the levelness of column 1 and make adjustments accordingly;

[0073] S3.2: Fix the bottom of the box column 1 to the deck 4 by spot welding;

[0074] S3.3: Remove temporary support device 3;

[0075] S3.4: Weld the box column 1 to the deck 4.

[0076] The panel of column 1 needs to be measured to ensure that column 1 is installed horizontally. This will prevent improper installation from affecting subsequent normal use. After the leveling is completed, the bottom of column 1 is spot-welded to fix it to deck 4, preventing further displacement. After removing the temporary supports, welding is performed on column 1 to further secure the connection between column 1 and deck 4. In this embodiment, column 1 can be measured using a level. In other embodiments, other methods can also be used for testing, as long as the horizontality of column 1 does not affect the overall accuracy.

[0077] In this embodiment, as Figure 5 As shown, bevel 2 is a single-sided bevel 2. The bottom of the box column 1 needs to be welded to the deck 4. Designing a single-sided bevel 2 makes operation more convenient. The pre-reserved slope of the single-sided bevel 2 allows the electric arc to penetrate deep into the root during welding, ensuring weld quality. At the same time, the prefabrication of the single-sided bevel 2 is simpler and faster, reducing production costs. In other embodiments, a multi-sided bevel 2 with a V-shape or other structures can also be designed, as long as it can produce a reverse deformation effect and offset the consumption during the welding process.

[0078] Specifically, the relative height difference between the two sides of bevel 2 is 5-8mm. During the welding process, the box column 1 will tilt horizontally, so a downward counter-deformation of 5-8mm is applied to the box column 1 to offset the wear during the welding process. In other embodiments, the height difference between the two sides of bevel 2 can be adjusted according to the actual dimensions of the box column 1.

[0079] This embodiment provides a container ship 5, including multiple column bases 1 and a main body. The column bases 1 are fixed to the main body of the container ship 5 using any of the column base installation methods described above. The container ship 5 requires the installation of multiple column bases 1. This column base installation method is simple to operate, and by adding anti-deformation measures to offset the wear and tear during the welding process, the installation accuracy of the column bases 1 is improved, saving on manual correction costs.

[0080] Furthermore, the installation positions of the multiple column pillars 1 are adapted to the dimensions of the containers. This arrangement ensures that the installation of the column pillars 1 can be compatible with the containers subsequently loaded onto the ship, avoiding situations where installation is incompatible, resulting in the inability to use the column pillars properly and wasting them.

[0081] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
