Description

Technical Field

[0001] The invention relates to a special pattern painting construction method for an outer plate area of ​​a large cruise ship, and in particular to a painting method and a cruise ship. Background Art

[0002] The marking of the outer plate area of ​​civil ships and offshore projects is relatively simple, mainly involving the ship name and some special marks of the owner. The pattern is mainly positioned by spot welding or pasting, and then sprayed according to the mark. The advantage of this solution is that the positioning is clear before painting and it is easy to find the boundary. The disadvantage is that if the owner modifies the ship name or mark, it will leave traces when removing the positioning, affecting the appearance. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the defect in the prior art that positioning is performed on the outer plate of a hull by spot welding or pasting, and marks are left when removing the positioning, which affects the appearance, and a painting method and a cruise ship are provided.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] Provided is a painting method for a hull outer plate, the painting method comprising: designing a two-dimensional painting pattern on a painting area of ​​the hull outer plate; performing three-dimensional lofting projection on the painting area of ​​the hull outer plate according to the painting pattern; and painting the hull outer plate according to a projection line of the three-dimensional lofting projection.

[0006] In this scheme, the two-dimensional designed painted pattern is positioned in the painted area of ​​the hull outer plate by using three-dimensional lofting projection, and the projection line of the three-dimensional lofting projection can be used to position the outer contour of the painted pattern on the hull outer plate. The use of projection positioning will not damage the structure of the hull outer plate, the positioning is accurate and the painting steps are saved, thereby improving construction efficiency.

[0007] Preferably, designing a two-dimensional painted pattern on the painted area of ​​the hull outer plate includes: designing a painted pattern and a color; and designing the painted pattern according to the painted pattern and the color, and the painted area.

[0008] In this plan, we first design the painting pattern to determine the painting style, select suitable colors to complete the painting pattern, select a suitable painting area based on the hull structure, and conduct two-dimensional design in combination with the painting pattern to form a complete painting pattern. The two-dimensional design can show the approximate effect of the painting pattern on the hull outer plate.

[0009] Preferably, performing three-dimensional lofting projection on the painted area of ​​the hull outer plate according to the painted pattern comprises: setting a positioning target point on the hull outer plate; and determining the position of the projection line of the three-dimensional lofting projection on the hull outer plate according to the positioning target point.

[0010] In this scheme, positioning targets are set according to the painted patterns to locate the approximate painted area on the hull outer plate and determine the position of the painted patterns, so that the position of the projection line on the hull outer plate can be determined more quickly during projection. Multiple projections can also ensure that the painted image is at the same position on the hull outer plate, and is not prone to offset, resulting in problems such as deformation of the painted pattern.

[0011] Preferably, determining the position of the projection line of the three-dimensional lofting projection on the outer hull plate according to the positioning target point comprises: positioning a projector according to the positioning target point; the projector projects a laser on the outer hull plate and generates a projection line.

[0012] In this solution, a projector is set to generate a projection line on the hull outer plate, and the projector is set according to a positioning target point on the hull outer plate to ensure that the projection line can be accurately projected at a desired position on the hull outer plate.

[0013] Preferably, after positioning the projector according to the positioning target point, the method further comprises: adjusting the placement position of the projector according to the position of the hull outer plate.

[0014] In this solution, the projector is adjusted according to the position of the hull outer plate to improve the projection effect of the projector so that the projection line can be clear and complete when projected on the hull outer plate.

[0015] Preferably, performing three-dimensional lofting projection on the painted area of ​​the hull outer plate according to the painted pattern comprises: performing three-dimensional lofting projection on the hull outer plate in divided areas according to the painted pattern.

[0016] In this scheme, projection on the outer plate of the hull in different areas can be performed in different areas to improve the precision of the operation. At the same time, the projection in different areas does not need to be performed when other areas are not being operated, thus saving energy.

[0017] Preferably, the projection lines of adjacent sub-regions partially overlap.

[0018] In this solution, when projecting by area, the projection lines of adjacent areas partially overlap so that the projection lines can be aligned at adjacent boundaries, ensuring that the projection lines of the areas are projected at corresponding positions of the hull outer plate without causing deviation.

[0019] Preferably, the hull outer plate is painted according to the projection line of the three-dimensional lofted projection, including: drawing a contour line on the hull outer plate according to the projection line; sticking a protective tape on the outside of the contour line; and spraying corresponding paint according to the color of the two-dimensional painted pattern in the area enclosed by the tape.

[0020] In this solution, the contour line of the color painting pattern is depicted on the outer hull plate according to the projection line to complete the external contour of the entire color painting pattern; a protective tape is pasted on the outside of the contour line to protect the areas on the outer hull plate that do not need to be painted around the painted area, preventing damage to the color painting pattern during the later coloring and spraying, which may affect the aesthetics; paint corresponding to the 2D design is sprayed inside the contour line to complete the overall color painting pattern.

[0021] Preferably, depicting the contour line on the outer hull plate according to the projection line includes: according to the projection line, using different colored markers to depict the contour line of the color painting pattern on the outer hull plate;

[0022] And / or, before, or at the same time as, or after pasting the protective tape on the outside of the contour line, the coloring method further includes: pasting a protective tape on the interference area and / or depicting the contour of the interference area.

[0023] In this solution, using markers to depict the contour line is convenient for workers to operate and has a low cost. For the openings or other interference areas on the outer hull plate, use protective tape for protection in advance, and / or use the method of manual drawing for the outer contour of the interference area to avoid the influence of coloring on the interference area.

[0024] Provide a cruise ship, and use the coloring method described in any one of the above to paint the color painting on the outer hull plate.

[0025] The positive and progressive effects of the present invention are as follows: By positioning the color painting pattern of the 2D design in the painted area of the outer hull plate using the 3D lofting projection method, the outer contour of the color painting pattern can be positioned on the outer hull plate using the projection line of the 3D lofting projection. Using projection positioning will not damage the structure of the outer hull plate, the positioning is accurate, and the coloring steps are saved, improving the construction efficiency.

[0033] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0034] In this embodiment, if Figure 1-7 As shown, a painting method is provided for the outer plate of a ship, and the painting method comprises:

[0035] Step S1: designing a two-dimensional painted pattern on the painted area of ​​the hull outer plate;

[0036] Step S2: Perform three-dimensional lofting projection on the painted area of ​​the hull outer plate according to the painted pattern;

[0037] Step S3: painting the hull outer plate according to the projection line of the three-dimensional lofting projection.

[0038] Among them, the two-dimensional designed painted pattern is positioned in the painted area of ​​the hull outer plate by using the three-dimensional lofting projection method, and the outer contour of the painted pattern can be positioned on the hull outer plate using the projection line of the three-dimensional lofting projection. The use of projection positioning will not damage the structure of the hull outer plate, the positioning is accurate and the painting steps are saved, thereby improving the construction efficiency.

[0039] In step S1, it includes:

[0040] Step S11: Designing painted patterns and colors;

[0041] Step S12: Designing a painting pattern according to the painting pattern and color, as well as the painting area.

[0042] First, design the painting pattern and determine the painting style, choose the appropriate color to complete the painting pattern, choose the appropriate painting area according to the hull structure, and conduct two-dimensional design based on the painting pattern to form a complete painting pattern. Through the two-dimensional design, you can see the approximate effect of the painting pattern on the hull outer plate.

[0043] In step S2, it includes:

[0044] Step S21: Setting a positioning target point on the outer plate of the hull;

[0045] Step S22: Determine the position of the projection line of the three-dimensional lofting projection on the hull outer plate according to the positioning target point.

[0046] According to the painted pattern, a positioning target is set to locate the approximate painted area on the hull outer plate, determine the position of the painted pattern, so that the position of the projection line on the hull outer plate can be determined more quickly during projection. Multiple projections can also ensure that the painted image is at the same position on the hull outer plate, and it is not easy to offset, resulting in deformation of the painted pattern and other problems. In other embodiments, other methods can also be used to locate the painted area on the hull outer plate, as long as the hull outer plate is not damaged and no traces are left.

[0047] In step S22, it includes:

[0048] Step S221: positioning the projector according to the positioning target;

[0049] Step S222: The projector projects laser light onto the outer hull plate and generates projection lines.

[0050] The projector is used to generate a projection line on the hull outer plate, and the projector is set according to the positioning target point on the hull outer plate to ensure that the projection line can be accurately projected on the expected position on the hull outer plate. In other embodiments, other devices other than the projector can also be used to generate the projection line.

[0051] Furthermore, after step S221, the method further includes:

[0052] Step S2211: Adjust the placement of the projector according to the position of the hull outer plate.

[0053] The projector is adjusted according to the position of the hull outer plate to improve the projection effect of the projector so that the projection line can be clear and complete when projected on the hull outer plate.

[0054] In step S2, it includes:

[0055] Step S23: Perform three-dimensional lofting projection on the hull outer plate in different areas according to the painted pattern.

[0056] Projecting on the hull outer plate in different areas can be used for different area operations, which improves the precision of the operation. At the same time, the projection in different areas does not need to be projected when other areas are not being operated, which saves energy.

[0057] Specifically, the projection lines of adjacent sub-areas partially overlap. When projecting the sub-areas, the partial overlap of the projection lines of adjacent areas can align the projection lines at the adjacent boundaries, ensuring that the sub-area projection lines are projected at the corresponding positions of the hull outer plate without deviation.

[0058] In step S3, it includes:

[0059] Step S31: drawing a contour line on the hull outer plate according to the projection line;

[0060] Step S32: Pasting a protective tape on the outside of the contour line;

[0061] Step S33: In the area enclosed by the tape, corresponding paint is selected for spraying according to the color of the two-dimensional painted pattern.

[0062] The outline of the painted pattern is drawn on the hull plate according to the projection line to complete the outer contour of the entire painted pattern; protective tape is pasted on the outside of the outline to protect the area around the painted area on the hull plate that does not need to be painted to prevent the painted pattern from being damaged during the subsequent color spraying and affecting the appearance; paint corresponding to the two-dimensional design is sprayed within the outline to complete the overall painted pattern.

[0063] In step S31, it includes:

[0064] Step S311: using markers of different colors to draw the outline of the painted pattern on the hull outer plate according to the projection line;

[0065] Before, at, or after step S32, the painting method further includes: first, pasting a protective tape on the interference area, or second, drawing the outline of the interference area, or third, pasting a protective tape on the interference area and drawing the outline of the interference area.

[0066] Using a marker to draw the outline is convenient and low-cost for workers. For holes or other interference areas on the hull outer plate, protective tape is used in advance to protect them, or the outer contour of the interference area is manually drawn to avoid the color painting from affecting the interference area. In other embodiments, other methods can also be used to process the color painting in the interference area.

[0067] In this embodiment, a cruise ship is provided, which uses any of the above-mentioned painting methods to paint on the outer plate of the hull.

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, but these changes and modifications all fall within the protection scope of the present invention.
