[0002] Bulb flats are commonly used in shipbuilding, and are a type of profile primarily employed in the shipbuilding industry. In recent years, with the rapid development of the shipbuilding industry, the demand for marine bulb flats has been strong. Generally, larger and standard vessels mostly use marine bulb flats for their main hull design, employing bulb flats of the same thickness and material as the adjacent plates as the hull material to enhance the ship's strength and reliability.

[0003] In shipbuilding, it's common to find one bulb flat with its ball end facing upwards and another with its ball end facing downwards, causing misalignment at the joint. When these two bulb flats need to be welded together, the existing technology involves cutting a portion from each of them and then adding an additional vertical bulb flat as a transition section to weld the three together. This method is complex, inefficient, inconvenient for on-site construction, and increases costs.

[0036] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0037] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0040] like Figures 1-3 As shown, this embodiment provides a marine spherical flat steel connecting device for connecting a first spherical flat steel 10 and a second spherical flat steel 20 whose interfaces are misaligned. The marine spherical flat steel connecting device includes a T-shaped plate 100. The T-shaped plate 100 includes a face plate and a web plate 130, which are vertically connected so that the web plate 130 defines an integrally formed first face plate 110 and a second face plate 120. The first face plate 110 has a first side end 1101, and the second face plate 120 has a second side end 1201. The first side end 1101 and the second side end 1201 are centrally symmetrical about the face plate. The first side end 1101 is welded to the ball head of the first spherical flat steel 10, and the second side end 1201 is welded to the ball head of the second spherical flat steel 20. Both ends of the web plate 130 are welded to the main body of the first spherical flat steel 10 and the main body of the second spherical flat steel 20, respectively.

[0041] Based on the above design, in this embodiment, the panel and web 130 are integrally formed, thereby improving the strength of the T-shaped plate 100 and extending its service life. The T-shaped plate 100 allows for the welding connection of the ball heads of the first ball flat steel 10 and the second ball flat steel 20, which are misaligned at their interfaces, ensuring the continuity of the first ball flat steel 10 and the second ball flat steel 20 and improving mechanical strength. Compared with existing technologies, this embodiment achieves a stable connection between the two misaligned first ball flat steel 10 and second ball flat steel 20 through the T-shaped plate 100, reducing the number of parts, eliminating the need for additional ball flat steel parts as in traditional technologies, reducing weld length and number, ensuring connection stability and mechanical strength, saving costs, facilitating operation, and improving work efficiency.

[0042] Furthermore, such as Figure 2As shown, in this embodiment, the first panel 110 further has a third side end 1102, and the second panel 120 further has a fourth side end 1202. The third side end 1102 and the fourth side end 1202 are arranged symmetrically about the panels. The third side end 1102 is away from the ball head of the second ball flat steel 20, and the fourth side end 1202 is away from the ball head of the first ball flat steel 10. The arrangement of the third side end 1102 and the fourth side end 1202 can provide a certain space for welding the web 130 to the main body of the first ball flat steel 10 and the main body of the second ball flat steel 20, thereby facilitating fillet welding of the web 130, improving construction efficiency, and ensuring the reliability of welding.

[0043] Optionally, in this embodiment, the first side end 1101 and the third side end 1102 are symmetrically arranged with respect to the first panel 110, and the second side end 1201 and the fourth side end 1202 are symmetrically arranged with respect to the second panel 120. That is, the panel has an axially symmetrical structure, which can not only improve the processing and manufacturing efficiency of the panel in the early stage, but also improve the uniformity of the force on the panel.

[0044] It should be noted that the shape of the panel and the web 130 is not specifically limited in this embodiment. Operators can flexibly set the shape of the panel and the web 130 according to actual needs, which will not be elaborated further here.

[0045] Optionally, in this embodiment, the length L of the third side end 1102 and the length L of the fourth side end 1202 are both set to between 10mm and 20mm. For example, the length L of the third side end 1102 and the length L of the fourth side end 1202 can both be set to 10mm, 15mm, 20mm, etc. Furthermore, optionally, in this embodiment, the length of the first side end 1101 is the same as the ball head width of the first ball flat steel 10, and the length of the second side end 1201 is the same as the ball head width of the second ball flat steel 20, thereby improving the reliability and stability of the welding.

[0046] like Figure 2 As shown, in this embodiment, the first side end 1101, the second side end 1201, the third side end 1102, and the fourth side end 1202 are all provided with chamfers R. Exemplarily, the angle of the chamfer R is 10° to 45°; for example, the chamfer R can be set to angle values ​​such as 10°, 30°, and 45°. The chamfer R is provided using a conventional beveling process in shipbuilding, which can reduce stress concentration and extend the service life of the T-shaped plate 100.

[0047] Optionally, the T-plate 100 is made of stainless steel, that is, it is made of stainless steel to improve the strength and service life of the marine ball flat steel connecting device and facilitate welding connection with the first ball flat steel 10 and the second ball flat steel 20.

[0048] Optionally, in this embodiment, the width of the web plate 130 is the same as the width of the main body of the first ball flat steel 10 and the width of the main body of the second ball flat steel 20, which facilitates the welding connection of the web plate 130 to the two main bodies respectively, and improves the reliability and stability of the marine ball flat steel connection device.

[0049] This embodiment also provides a ship that includes the aforementioned marine bulb flat steel connecting device. This marine bulb flat steel connecting device ensures the continuity of the first bulb flat steel 10 and the second bulb flat steel 20, preventing disconnection and misalignment, improving the ship's safety performance, extending its service life, and saving costs.

[0050] This embodiment also provides a method for connecting marine spherical flat steel bars. This method is applied to the aforementioned marine spherical flat steel bar connecting device and includes:

[0051] The first ball flat steel 10 or the second ball flat steel 20 is cut at a preset distance M. Since the shipbuilding specifications require that the size of a single part be at least 300mm, the preset distance M is set to be no less than 300mm in this embodiment. Figures 1-2 The example shown is cutting the second ball flat steel 20 at a preset distance M of 300mm.

[0052] A T-shaped plate 100 with a preset distance M is placed between the first bulb flat steel 10 and the second bulb flat steel 20, and then welded together with the T-shaped plate 100. In other words, the preset distance M that is 300mm short is replaced by the T-shaped plate 100 in this embodiment, and then the T-shaped plate 100 is welded to the first bulb flat steel 10 and the second bulb flat steel 20 by fillet welding, thereby ensuring the continuity of the first bulb flat steel 10 and the second bulb flat steel 20 and avoiding the risk of breakage or misalignment.

[0053] The method for connecting flat steel spheres for ships is simple, easy to operate, and convenient to construct, which can improve work efficiency and achieve the goal of saving costs.
