Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a box column installation method for a container ship in a segmented stage and a container ship. Background Art

[0002] At the heart of container ship construction, precise installation of deck columns is crucial for ensuring the ship's structural strength and efficient, safe container stacking. As the core transfer path for container stacking loads, the weld quality and relative positioning accuracy of the column's base and deck structure directly determine the ship's operational safety and service life.

[0003] Existing container ship deck column installation technology faces significant bottlenecks in precision control and efficiency. This technology, heavily reliant on manual experience and uncontrollable processes, has become a significant factor restricting shipbuilding quality and progress. New, high-precision technologies are urgently needed to achieve precise positioning and installation of column columns to overcome this long-standing engineering challenge. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defect in the prior art that various factors lead to deviation in the installation accuracy of box columns and the need for repeated corrections, and to provide a box column installation method for the segmented stage of a container ship and a container ship.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] A method for installing a box column in a block stage of a container ship, wherein the deck of the container ship is placed vertically during the block stage. The method comprises the following steps:

[0007] S1: Pre-processing the groove at the bottom of the box column;

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

[0009] S2: moving the box column to the deck pre-positioning position;

[0010] S3: Fix the box column on the deck.

[0011] In this solution, installation is performed during the container ship's block phase, allowing the columns to be constructed sideways for easier construction. Prefabricating the grooves at the bottom of the columns offsets welding losses, preventing the columns from warping horizontally during welding. Deformation-compensating welding eliminates the need for secondary corrections and reduces labor costs. Pre-positioning on the deck prior to installation effectively improves column installation accuracy, making subsequent installation more efficient and simple. After installation, the columns are securely connected to the deck, ensuring a long service life.

[0012] Preferably, before the step of pre-positioning the box column installation position on the deck, the method further comprises the following steps:

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

[0014] In this solution, before installing the box column, the flatness of the deck is adjusted first to avoid the subsequent welding work being unable to proceed due to the uneven deck surface. In addition, the box column is prone to bulging after installation, which reduces the service life of the box column. Leveling in advance helps improve operation accuracy and extend the service life of the box column.

[0015] Preferably, the step of pre-positioning the box column installation position on the deck further comprises the steps of:

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

[0017] S1.3: Temporary support devices shall be provided below the structural line.

[0018] In this solution, pre-positioning is performed according to the installation drawings, ensuring that the subsequent installation of the box columns meets the design requirements. Drawing structural lines on the deck facilitates practicality and accurate positioning without damaging the deck and box column structure, allowing for easy removal after installation. A temporary support device is installed below the structural line. During subsequent operations, the box columns are mounted on this temporary support device, preventing displacement and providing a certain degree of support for the box columns.

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

[0020] In this solution, two temporary support devices are set up for better stability, and are less likely to shake or move during operation, avoiding increased construction difficulty due to insufficient support effect and reduced accuracy of box column installation.

[0021] Preferably, the step S2 further includes:

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

[0023] In this solution, a crane or other tool is used to lift the box column onto the temporary support device, which facilitates subsequent adjustment of the box column. The temporary support device has a good supporting effect and is less likely to cause displacement than directly operating in the lifting stage, resulting in reduced accuracy in box column installation.

[0024] Preferably, the step S3 further includes:

[0025] S3.1: Measure the levelness of the box column and adjust it;

[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 columns to the deck.

[0029] In this solution, the level of the box column panel needs to be measured to ensure that the box column is installed horizontally to avoid affecting subsequent normal use due to improper installation. After the level adjustment is completed, the bottom of the box column is spot welded to fix the box column on the deck so that it will not move. After removing the temporary support, the box column is welded to make the connection between the box column and the deck tighter.

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

[0031] In this solution, the bottom of the box column needs to be welded to the deck. The design of a single-sided bevel makes the operation more convenient. The single-sided bevel has a reserved inclined surface, so that the arc can penetrate deep into the root during welding, ensuring the quality of welding. 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 groove is 5-8 mm.

[0033] In this solution, the box column will be tilted upwards during the welding process, so a 5-8mm reverse deformation is applied downwards to the box column to offset the consumption during the welding process.

[0034] A container ship comprises a plurality of the box columns and a body, wherein the box columns are fixed to the body by the box column installation method as described in any one of the above settings.

[0035] In this solution, a container ship needs to install multiple box columns. The box column installation method is simple to operate. By adding and placing anti-deformation, the consumption in the welding process is offset, which improves the accuracy of box column installation and saves labor correction costs.

[0036] Preferably, the installation positions of the plurality of box columns are adapted to the size of the container.

[0037] In this solution, the above-mentioned setting enables the installation of the box column to be coordinated with the subsequent containers on board, avoiding the situation where the box column cannot be adapted after installation, resulting in abnormal use and waste of the box column.

[0038] The positive benefits of this invention are as follows: This method of installing the box columns offsets welding wear by pre-fabricating the grooves at the bottom of the columns, preventing the column from warping horizontally during welding. The counter-deformation offset welding eliminates the need for secondary corrections, reducing 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 simple. After installation, the box columns are securely connected to the deck, extending their service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0051] In this embodiment, if Figure 1-Figure 5 As shown, a method for installing a box column in the block stage of a container ship is provided. In the block stage, the deck 4 of the container ship 5 is placed vertically. The method for installing the box column 1 includes the following steps:

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

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

[0054] S2: Move the box column 1 to the pre-positioning position of the deck 4;

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

[0056] During the installation phase of the container ship 5, the box column 1 can be constructed sideways, facilitating construction. Prefabrication of the groove 2 at the bottom of the box column 1 offsets welding losses, preventing the horizontal warping of the box column 1 during welding. Anti-deformation offset welding eliminates secondary corrections and reduces manual correction costs. Pre-positioning on the deck 4 prior to installation effectively improves the accuracy of the box column 1 installation, making the subsequent installation process more efficient and simple. After installation, the box column 1 is securely connected to the deck 4, extending its service life.

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

[0058] Furthermore, before the step of pre-positioning the installation position of the box column 1 on the deck 4, the step of:

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

[0060] Before installing the box column 1, the flatness of the deck 4 should be adjusted first to avoid the subsequent welding work being unable to proceed due to the uneven surface of the deck 4. In addition, the box column 1 is prone to bulging after installation, which reduces the service life of the box column 1. Leveling in advance helps to improve the operation accuracy and extend the service life of the box column 1.

[0061] Specifically, in this embodiment, the sunken portion of the deck 4 is heated with a spray gun to expand the sunken portion, thereby improving the flatness of the deck 4. In other embodiments, other methods may be used, such as filling the sunken portion with paving materials or pressing the protruding portion with a pressure device, as long as the surface of the deck 4 is flattened without affecting the installation of the box column 1.

[0062] In this embodiment, if Figure 2 As shown, the step: pre-positioning the installation position of the box column 1 on the deck 4, further comprising the steps:

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

[0064] S1.3: Set up temporary support devices 3 below the structure line.

[0065] Pre-positioning according to the installation drawings ensures that the subsequent installation of the box column 1 meets the design requirements. By drawing the structural line on the deck 4, it is convenient, practical, and accurate in positioning, without damaging the structure of the deck 4 and the box column 1, and can be erased after installation. A temporary support device 3 is set below the structural line. During subsequent operations, the box column 1 is erected on the temporary support device 3 without displacement, providing a certain degree of support for the box column 1.

[0066] Specifically, in this embodiment, the box column 1 is a type of iron outfitting, and is positioned and installed according to a pre-designed iron outfitting installation drawing to avoid deviations between the actual installation and the drawing, which may result in subsequent inability to use normally and require adjustments, increasing labor costs, and damaging the structure of the deck 4 and the box column 1, affecting its service life. The temporary support structure in this embodiment is a temporary tire frame, which is constructed from multiple hollow iron frames that match the size of the box column 1. It is convenient for production and can be flexibly moved. It can be recycled after use and will not cause waste of resources. In other embodiments, the temporary support device 3 can also be constructed using other components, and it only needs to support the box column 1.

[0067] Further, if Figure 4 As shown, at least two temporary support devices 3 are set below the structural line. Setting two temporary support devices 3 has better stability and is not prone to shaking or moving during operation, avoiding increased construction difficulty due to insufficient support effect and reduced installation accuracy of the box column 1.

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

[0069] S2.1: Lift 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 a crane or other tool to hoist the box column 1 onto the temporary support device 3 facilitates subsequent adjustment of the box column 1. The temporary support device 3 provides a good support effect and is less likely to cause displacement, which would reduce the installation accuracy of the box column 1, compared to direct operation during the hoisting stage. In other embodiments, other tools such as a transport vehicle can also be used to move the box column 1, and adjustments can be made according to on-site equipment without specific limitations.

[0071] In this embodiment, if Figure 3 As shown, step S3 also includes:

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

[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 level of the panel of the box column 1 needs to be measured to ensure that the box column 1 is installed horizontally to avoid improper installation affecting subsequent normal use. After the level adjustment is completed, the bottom of the box column 1 is spot welded to fix the box column 1 on the deck 4 so that it will not move. After removing the temporary support, the box column 1 is welded to further tighten the connection between the box column 1 and the deck 4. In this embodiment, the box column 1 can be measured with a spirit level. In other embodiments, other methods can also be used for detection, as long as the levelness of the installation of the box column 1 does not affect the overall accuracy.

[0077] In this embodiment, if Figure 5 As shown, the groove 2 is a single-sided groove 2. The bottom of the column 1 needs to be welded to the deck 4. Designing a single-sided groove 2 facilitates operation. The reserved bevel of the single-sided groove 2 allows the arc to penetrate deep into the root during welding, ensuring weld quality. The single-sided groove 2 also simplifies and accelerates prefabrication, reducing production costs. In other embodiments, a multi-sided groove 2, such as a V-shaped groove, can also be designed, as long as it can produce a deformation-reducing effect and offset welding losses.

[0078] Specifically, the relative height difference between the two sides of the groove 2 is 5-8 mm. During the welding process, the box column 1 will tilt upward horizontally, so a 5-8 mm downward deformation 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 the groove 2 can be adjusted according to the actual size of the box column 1.

[0079] In this embodiment, a container ship 5 is provided, comprising a plurality of columns 1 and a main body. The columns 1 are secured to the main body of the container ship 5 using any of the above-described column installation methods. The container ship 5 requires installation of multiple columns 1. This column installation method is simple to operate, and by adding and placing counter-deformation to offset wear during welding, the column 1 installation accuracy is improved, saving manual correction costs.

[0080] Furthermore, the installation positions of the multiple box columns 1 are adapted to the size of the container. The above arrangement enables the installation of the box columns 1 to be compatible with the subsequent containers on board, avoiding the situation where the box columns 1 cannot be adapted after installation, resulting in inability to use them normally and wasting the box columns 1.

[0081] Although specific embodiments of the present invention have been described above, those skilled in the art will appreciate that these are merely illustrative and that the scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of the present invention.
