Description

Technical fields:

[0001] This invention relates to the field of weight reduction design, and in particular to a weight reduction hole structure and its ship. Background technology:

[0002] Currently, in the shipbuilding industry, weight and center of gravity control is a major design challenge for some ship types (such as Ro-Ro passenger ships). The weight of the superstructure longitudinal and transverse beams (hereinafter referred to as T-beams) located above the center of gravity of a Ro-Ro passenger ship has a significant impact on the overall center of gravity of the ship.

[0003] Weight reduction holes are a common design feature on ship structural components. Their purpose is to reduce weight, such as the weight of a T-beam. A certain number of weight reduction holes of appropriate size and shape are arranged at appropriate locations on the web of the T-beam. The shape of these holes is generally round or oblong. The shape of these weight reduction holes is generally a regular shape, and they are also designed symmetrically, so they do not affect the center of gravity of the ship.

[0004] Therefore, the inventors hope to design a weight-reducing hole structure that, to a certain extent, can adjust the center of gravity of the ship while having the basic function of weight reduction. This would help solve the technical problem that there is no existing technology that can adjust the center of gravity of equipment through a weight-reducing hole structure.

[0036] Most of the weight-reducing holes in the existing technology are either round or elongated. In order to ensure optimized design in terms of weight and strength, they are generally made of symmetrical regular pattern holes and the layout is also symmetrical. However, the weight-reducing holes in the existing technology only have the function of weight reduction.

[0037] When designing structures such as ship hulls, the inventors also need to consider the center of gravity and adjust it. Therefore, the inventors believe that the center of gravity adjustment and weight reduction can be combined into one structure, so that the purpose of adjusting the center of gravity of the structure can be achieved while meeting the design requirements of weight reduction.

[0039] like Figure 1 As shown, in one embodiment, the present invention provides a weight-reducing hole structure, the weight-reducing hole structure including an opening body 1;

[0040] The opening body 1 is provided with at least one weight reduction hole 2, the weight reduction hole 2 having an elongated hole 21 along a predetermined first direction and a protrusion 22 on the elongated hole along a predetermined second direction.

[0041] This embodiment provides an implementation of a weight-reducing hole structure. The opening body 1 serves as the carrier of the weight-reducing hole 2. The opening body 1 is used as a structural component, on which the weight-reducing hole 2 is provided. The elongated hole 21 and the protrusion 22 are an integral hole with an irregular shape. The length direction of the elongated hole 21 is the predetermined first direction, i.e. Figure 1 The horizontal direction is defined by the convexity 22, while the protrusion 22 represents the predetermined second direction. Figure 1 In the longitudinal direction, both are at an angle to each other. Preferably, the angle between them is 90 degrees vertical. The protrusion 22 mentioned here is also part of the overall weight-reducing hole 2, but it has a certain displacement and extension in different directions. Since the elongated hole 21 is also a regular shape, it can also be symmetrically arranged on the opening body 1, such as... Figure 1 The centerline shown (i.e., the dashed line in the figure) indicates that, without considering the protrusion 22, the elongated hole 21 is symmetrically arranged vertically along the centerline. Alternatively, the center of the opening body 1 can be changed along a predetermined second direction, for example... Figure 1 As shown, the center of gravity will be further downward than when only the elongated hole 21 is present. It should be noted that, since the primary goal is weight reduction, the overall area of ​​the weight-reducing hole 2 should be larger than the area of ​​the regular hole required for weight reduction. In summary, the weight-reducing hole structure in this embodiment helps to solve the technical problem that there is no existing technology that can adjust the center of gravity of a device through a weight-reducing hole structure.

[0042] in addition, Figure 2 neutralization Figure 3 In, and Figure 4 The text presents a comparison between existing technologies and the structure of this invention. Figure 2 The first elongated hole in the middle has the same width as the elongated hole 21, and adopts... Figure 2 The alternative design scheme is as follows: if the existing technology uses a circular weight-reduction hole, then adopt... Figure 3 If, in the design scheme shown in the second elongated hole, the width of the structure is greater than the width of the elongated hole 21, then the following can be adopted: Figure 4 The design.

[0043] In one embodiment, the edges of the elongated hole 21 and the protrusion 22 are smoothly transitioned by rounded arcs.

[0044] This embodiment provides an edge transition structure for the elongated hole 21 and the protrusion 22. Using a smooth, rounded transition reduces stress and ensures the original strength of the opening body 1, while also facilitating processing, such as by wire cutting or laser cutting.

[0045] In one embodiment, the opening body 1 is a T-shaped profile, the weight reduction hole 2 is provided on the web plate 11, the predetermined first direction is the length direction of the opening body 1, and the predetermined first direction and the predetermined second direction have an included angle.

[0046] This embodiment provides a specific implementation of the opening body 1. In this embodiment, the opening body 1 adopts a T-shaped profile. The cross-section of the T-shaped profile is T-shaped. The longitudinal plate structure is called the web, and the top transverse plate structure is called the wing. The T-shaped profile is widely used in the design of structural components. In this embodiment, the weight reduction hole 2 is a through hole set on the web.

[0047] like Figure 5 As shown, in one embodiment, a first edge 111 on one side of the web 11 is connected to a wing plate 12 of a T-shaped profile, and at least two through holes 13 with a predetermined interval are provided on the second edge 112 on the other side of the web 11 along the length direction of the web 11. Weight reduction holes 2 are provided between adjacent through holes 13.

[0048] This embodiment provides a specific implementation in which a through hole 13 is provided on the web plate 11. In addition to being used as a structural component on its own, the T-shaped profile may also be used in multiple ways. The through hole 13 is a hole designed to connect multiple T-shaped profiles.

[0049] In one embodiment, the through hole 13 is an open elongated hole, one end of the through hole 13 is semi-circular, and the other end of the through hole 13 extends to the first edge 111.

[0050] In this embodiment, a specific structure of an inertial hole 13 is provided, with one end being a semi-circular arc and the other end extending to the first edge 111 to form an open opening so that subsequent connecting structural components can be fixedly connected.

[0051] In one embodiment, the closest distance between the edge of the weight-reducing hole 2 and the edge of the through hole 13 is greater than 7.5 mm, the closest distance between the edge of the weight-reducing hole 2 and the first edge 111 on one side of the web 11 is greater than 100 mm, and the width of the web 11 is X mm.

[0052] This embodiment provides a specific layout for the weight-reducing holes 2. These dimensions are a preferred dimensional relationship value based on the final dimensions of the T-shaped profile. It is necessary to ensure the functionality, rationality, and arrangement of the weight-reducing holes 2 and the through holes 13, and to ensure that the strength of the T-shaped profile is not significantly compromised. Figure 5As shown, the centerline of the elongated hole 21 is equidistant from the left and right through holes 13 along the first direction, the distance between adjacent through holes 13 is B, the width of the web 11 is H, and the closest distance between the edge of the weight reduction hole 2 and the edge of the through hole 13 is S.

[0053] In one embodiment, the elongated hole 21 is a through hole arranged along the predetermined first direction and with semi-circular ends. The length of the elongated hole 21 is equal to the width of the web 11, the width of the elongated hole 21 is less than 0.6 times the width of the web 11, and the radius of the semi-circular through holes at both ends of the elongated hole 21 is less than 0.25 times the width of the web 11.

[0054] This embodiment provides a specific structure for the elongated hole 21. The structural relationship in this embodiment can ensure strength and prevent stress concentration. Furthermore, the weight distribution on the T-shaped profile is adjusted in an asymmetrical manner, thereby changing the position of the center of gravity.

[0055] In one embodiment, the protrusion 22 is located on the edge of one side of the elongated hole 21, and the middle part of the edge of the protrusion 22 is an arc segment with a radius equal to the radius of the through hole. The two ends of the edge of the protrusion 22 are fitted and smoothly transitioned to the edge of the elongated hole 21.

[0056] This embodiment provides a specific implementation method for connecting the protrusion 22 and the elongated hole 21.

[0057] In one embodiment, the present invention also provides a ship having a weight-reducing hole structure, the ship including the weight-reducing hole structure;

[0058] The protrusion of protrusion 22 faces upward.

[0059] This embodiment provides a specific implementation of a ship with a weight-reducing hole structure. To lower the center of gravity, the protrusion 22 is oriented upwards, thus lowering the center of gravity of the T-shaped profile.

[0060] In one embodiment, the opening body 1 is a T-shaped profile, and the first edge 111 on one side of the web 11 is connected to the wing plate 12 of the T-shaped profile. At least two through holes 13 with a predetermined interval are provided on the second edge 112 on the other side of the web 11 along the length direction of the web 11.
