Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a signal light installation method, a shipbuilding method, and a ship. Background Technology

[0002] The installation angle and accuracy of a ship's audible and visual signal lights are crucial factors in ensuring safe navigation. Correct installation angles ensure that other vessels can clearly identify a ship's navigation status at night or in adverse weather conditions, thus preventing collisions.

[0003] Heavy-lift vessels are equipped with a total of five audible and visual signal lights. A stern light is located at the stern, and at the bow, a port light is located on the port side, a starboard light on the starboard side, an aft mast light on the aft mast, and a foremast light on the foremast. Each navigation signal light is connected and fixed to its corresponding light holder via multiple screws. Because the light holders are welded to the hull after it has been formed, the coordinate system used in the manufacturing and drilling of the light holders is inconsistent with the hull's coordinate system. Therefore, the installation angle and position of the light holders relative to the hull's coordinates may deviate when installed, thus affecting the accuracy of the subsequent lighting angle and range.

[0004] Currently, the mounting points for audible and visual signal lights are typically installed after the hull is formed on land. During sea trials, small boats circle the vessel, repeatedly verifying the angle of the lights using instruments. The angle of the navigation lights is then repeatedly adjusted or corrected by measuring and observing the range of the lights. Due to the high safety risks and difficulty in maintaining stability during maritime operations, the measurement process is challenging, inaccurate, and inefficient.

[0005] Therefore, there is an urgent need for a signal light installation method, a ship manufacturing method, and a ship to solve the above problems. Summary of the Invention

[0006] According to one aspect of the present invention, the object is to provide a signal light installation method that simplifies the calibration process and ensures the accuracy of signal light installation.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] Traffic light installation methods include:

[0009] S10. Set a marking structure on the lamp holder;

[0010] S20. Establish a baseline on the ground at the shipbuilding site;

[0011] S30. When the lamp holder is in the preset installation position, the preset coordinate value corresponding to the marking structure is obtained with reference to the baseline.

[0012] S40. Pre-install the lamp holder on the hull of the vessel;

[0013] S50. Using the baseline as a reference, measure the actual coordinate values ​​of the marking structure on the pre-installed lamp holder;

[0014] S60. Adjust the installation position of the lamp holder so that the actual coordinate value is consistent with the preset coordinate value.

[0015] As a preferred embodiment of the signal light installation method provided by the present invention, the lamp holder is provided with a plurality of the aforementioned marking structures, which are arranged at intervals between each other on the lamp holder.

[0016] As a preferred embodiment of the signal light installation method provided by the present invention, a plurality of the marking structures are arranged in a rectangular array on the lamp holder.

[0017] As a preferred embodiment of the signal light installation method provided by the present invention, the lamp holder has a mounting hole for connecting a signal light, the mounting hole is configured to connect a signal light, and the marking structure is concentrically arranged with the mounting hole; and / or,

[0018] The marking structure is a cross-shaped reflective target.

[0019] As a preferred embodiment of the signal light installation method provided by the present invention, the reference line includes a longitudinal reference line and a transverse reference line. The longitudinal reference line is parallel to the center line of the hull, and the transverse reference line is perpendicular to the center line. The center line is set along the longitudinal direction of the hull.

[0020] As a preferred embodiment of the signal light installation method provided by the present invention, the longitudinal reference line includes a port reference line and a starboard reference line. The port reference line is drawn on the ground on the port side of the hull, and the starboard reference line is drawn on the ground on the starboard side of the hull.

[0021] As a preferred embodiment of the signal light installation method provided by the present invention, the distance between the port side reference line and the center line is 20000 mm; and / or,

[0022] The distance between the starboard baseline and the centerline is 20,000 mm.

[0023] As a preferred embodiment of the traffic light installation method provided by the present invention, the following steps are performed after S60:

[0024] S70. Install the signal light body onto the lamp holder.

[0025] According to another aspect of the present invention, an object is to provide a ship manufacturing method comprising: manufacturing a ship's hull on the ground at a manufacturing site; the ship manufacturing method further comprising, after the hull is manufactured, performing a signal light installation method as described in any of the above embodiments.

[0026] According to another aspect of the present invention, the object is to provide a ship manufactured using the shipbuilding method described above.

[0027] The beneficial effects of this invention are:

[0028] The signal light installation method provided by this invention includes: S10, setting a marking structure on the lamp holder; S20, setting a baseline on the ground at the shipbuilding site. The marking structure facilitates the determination and adjustment of the lamp holder's installation position. The baseline establishes a coordinate system with the ship hull as a reference, serving as a benchmark for adjusting the lamp holder's installation position and unifying the coordinate systems of the ship hull and the lamp holder. S30, when the lamp holder is in the preset installation position, the preset coordinate values ​​corresponding to the marking structure are obtained with reference to the baseline. These preset coordinate values ​​serve as the target for subsequent lamp holder installation position adjustments. S40, the lamp holder is pre-installed on the ship hull; S50, the actual coordinate values ​​of the marking structure on the pre-installed lamp holder are measured with reference to the baseline; S60, the installation position of the lamp holder is adjusted to unify the actual coordinate values ​​with the preset coordinate values. Through these steps, the lamp holder can be adjusted to the required installation position. The above-described signal light installation method allows for the installation and calibration of the light holders to be carried out on land after the ship's hull construction is completed, eliminating the need for repeated on-water operations after the ship is launched. This simplifies the signal light installation and calibration process and ensures the accuracy of the signal light installation. Attached Figure Description

[0050] This embodiment provides a signal light installation method, a ship manufacturing method, and a ship. The ship is manufactured using the aforementioned ship manufacturing method.

[0051] The ship manufacturing method includes the following steps: First, the hull 10 of the ship is manufactured on the ground at the manufacturing site. The ship manufacturing method also includes: after the hull 10 is manufactured, the signal light installation method provided in this embodiment is performed to assemble and adjust the positions of the signal lights at various locations on the hull 10.

[0052] Figure 1 A flowchart illustrating the signal light installation method provided in an embodiment of the present invention is shown; Figure 2 This diagram illustrates the installation of signal lights on a ship according to an embodiment of the present invention. (Refer to...) Figure 1 and Figure 2 The signal light installation method provided in this embodiment specifically includes the following steps:

[0053] Step S10: Set the marking structure 5 on the lamp holder. By setting the marking structure 5, it is easy to determine and adjust the installation position of the lamp holder.

[0054] Specifically, Figure 3 This diagram illustrates a marking structure for the foremast light mount of a ship provided in an embodiment of the present invention. Figure 4 This diagram illustrates a marking structure for the aft mast light mount of a ship provided in an embodiment of the present invention. Figure 5 This diagram illustrates a marking structure for the port side lamp holder of a ship provided in an embodiment of the present invention. Figure 6 This diagram illustrates a starboard lamp holder marking structure provided in an embodiment of the present invention. Figure 7 This diagram illustrates a marking structure for a ship's stern light mount according to an embodiment of the present invention. (Refer to...) Figures 3-7 The lamp holder consists of multiple components, specifically including a stern lamp holder 20, a port lamp holder 30, a starboard lamp holder 40, aft mast lamp holder 50, and foremast lamp holder 60. Among them, such as... Figure 2 As shown, the stern light mount 20 is located at the stern of the hull 10, the port side light mount 30 is located on the port side of the hull 10, the starboard side light mount 40 is located on the starboard side of the hull 10, the aft mast light mount 50 is located on the aft mast of the hull 10, and the foremast light mount 60 is located on the foremast of the hull 10.

[0055] More specifically, the lamp holder is provided with multiple marking structures 5, which are arranged at intervals between each other. By calibrating the multiple marking structures 5, the accuracy and reliability of the lamp holder position calibration can be further improved.

[0056] Preferably, multiple marking structures 5 are arranged in a rectangular array on the lamp holder. In this embodiment, each lamp holder is provided with four marking structures 5, which are evenly distributed to form a rectangular array.

[0057] More specifically, the lamp holder has a mounting hole configured to connect a signal light, and the marking structure 5 is concentrically positioned with the mounting hole. In this embodiment, the mounting hole is specifically a screw hole, allowing the signal light to be connected to the corresponding lamp holder via screws.

[0058] Preferably, the marking structure 5 is a cross-shaped reflective target. This design facilitates rapid and accurate identification by equipment such as laser rangefinders, improving construction efficiency.

[0059] For example, the stern light mount 20 has four first connection holes 21, each with a concentric cross-shaped reflector. The port side light mount 30 has four second connection holes 31, each with a concentric cross-shaped reflector. The starboard side light mount 40 has four third connection holes 41, each with a concentric cross-shaped reflector. The aft mast light mount 50 has four fourth connection holes 51, each with a concentric cross-shaped reflector. The foremast light mount 60 has four fifth connection holes 61, each with a concentric cross-shaped reflector.

[0060] Step S20: Establish a baseline on the ground at the shipbuilding site. This baseline forms a coordinate system with respect to the hull 10, serving as a reference for adjusting the lamp holder installation position and unifying the coordinate systems of the hull and the lamp holder.

[0061] Specifically, Figure 8 This diagram illustrates the setting of a reference line for a ship according to an embodiment of the present invention. (Refer to...) Figure 8 The reference line specifically includes a longitudinal reference line and a transverse reference line 1. The longitudinal reference line is parallel to the center line 2 of the hull 10, and the transverse reference line 1 is perpendicular to the center line 2. The center line 2 is set along the longitudinal direction of the hull 10.

[0062] More specifically, the longitudinal reference line includes the port reference line 3 and the starboard reference line 4. The port reference line 3 is drawn on the ground on the port side of the hull 10, and the starboard reference line 4 is drawn on the ground on the starboard side of the hull 10.

[0063] In this embodiment, the distance between the port side reference line 3 and the center line 2 is 20,000 mm, and the distance between the starboard side reference line 4 and the center line 2 is 20,000 mm. In other embodiments, the distance between the port side reference line 3 and the center line 2, and the distance between the starboard side reference line 4 and the center line 2, can be selected according to the actual dimensions of the hull 10.

[0064] Step S30: When the lamp holder is in the preset installation position, a preset coordinate system is established based on the baseline. The origin of the preset coordinate system can be determined by the operator according to their needs. In this embodiment, the origin of the preset coordinate system can be selected as the center position on the longitudinal and transverse deck of the hull 10. The preset coordinate point corresponding to the marker structure 5 is obtained, and the X, Y, and Z values ​​of the preset coordinate point are recorded, i.e., the preset coordinate values. Among them, the X value represents the coordinate of the marker structure 5 in the longitudinal direction of the hull 10 under the preset coordinate system; the Y value represents the coordinate of the marker structure 5 in the transverse direction of the hull 10 under the preset coordinate system; and the Z value represents the coordinate of the marker structure 5 in the vertical direction of the hull 10 under the preset coordinate system.

[0065] Step S40: Pre-install the lamp holder on the hull 10 of the vessel. In this embodiment, spot welding is used to achieve the pre-installation of the lamp holder.

[0066] Step S50: Using the baseline as a reference, measure the actual coordinates of the marking structure 5 on the pre-installed lamp holder.

[0067] Step S60: Adjust the installation position of the lamp holder so that the actual coordinate value is consistent with the preset coordinate value. In this embodiment, it is only necessary to cut off the solder joints of the lamp holder before it is installed, adjust the position, and then re-solder.

[0068] It should be noted that the following steps are required after S60:

[0069] Step S70: Install the signal light body onto the lamp holder. This completes the signal light installation process.
