Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, and in particular to deck reinforcement structures and methods for installing deck reinforcement structures. Background Technology

[0002] A ship's winch consists of a cable drum, a winch base, and a power mechanism. The winch base is mounted on the deck, the cable drum is rotatably mounted on the winch base, and the power mechanism is mounted on the aft side of the deck. The power mechanism is suspended below the cable drum via a main shaft and drives the cable drum to rotate, thus achieving the winding action of the rope. To ensure that the dynamic and static loads generated by the ship's winch do not damage the deck, a suitable reinforcing structure needs to be installed in the area where the winch base is located.

[0003] During ship design and construction, due to constraints such as processing procedures, reinforcement structures can only be installed and fixed after the main ship structure has been completed. In existing technologies, to ensure the strength of the reinforcement structure, extensive modifications to the original structure are required during installation. This results in limited construction space, difficulties in installation, and a waste of human and material resources.

[0004] Therefore, there is an urgent need to invent a deck reinforcement structure and a method for installing the deck reinforcement structure in order to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a deck reinforcement structure and an installation method for the deck reinforcement structure, so as to improve the structural strength of the deck with the winch base installed and improve the installation efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A deck reinforcement structure, with a winch base fixed to the front of the deck, the deck reinforcement structure comprising:

[0008] A ring-shaped structure, wherein the end face of the ring-shaped structure is connected and fixed to the back of the deck, the two radial ends of the ring-shaped structure are arranged opposite to each other, and the two radial ends of the ring-shaped structure extend outward along the extension direction of the deck and are connected and fixed to a crossbeam or longitudinal beam; and

[0009] A cylindrical structure is connected and fixed to the end face of the annular structure away from the deck. The axis of the cylindrical structure is perpendicular to the end face of the annular structure. The two radial ends of the cylindrical structure are arranged opposite to each other. The two radial ends of the cylindrical structure extend outward along the extension direction of the deck and are connected and fixed to the crossbeam or longitudinal beam.

[0010] As an optional feature, the deck reinforcement structure also includes:

[0011] The first reinforcing member is simultaneously connected and fixed to the outer wall of the cylindrical structure, the deck, and the crossbeam or the longitudinal beam.

[0012] As an optional solution, the first reinforcing member is provided on the outer wall of the cylindrical structure along both the transverse and longitudinal directions, and each of the first reinforcing members is simultaneously connected and fixed to the outer wall of the cylindrical structure, the deck, and the crossbeam or the longitudinal beam.

[0013] As an optional feature, the deck reinforcement structure also includes:

[0014] The second reinforcing member is provided on the outer wall of the cylindrical structure along both the first and second directions. Each second reinforcing member is simultaneously connected and fixed to the outer wall of the cylindrical structure and the deck. The first direction and the second direction are perpendicular to each other. The angle between the first direction and the lateral direction is 45°, and the angle between the second direction and the lateral direction is 45°.

[0015] As an optional solution, the end face where the annular structure is connected and fixed to the cylindrical structure includes a first region located inside the cylindrical structure and a second region located outside the cylindrical structure, wherein the area of ​​the first region is larger than the area of ​​the second region.

[0016] As an optional solution, the difference between the outer diameter of the annular structure and the outer diameter of the cylindrical structure is 35mm to 45mm.

[0017] Alternatively, the inner diameter of the cylindrical structure can be equal to the inner diameter of the winch base.

[0018] Alternatively, the axial length of the cylindrical structure is equal to the height of the crossbeam or the longitudinal beam.

[0019] As an alternative, the annular structure is formed by cutting a first plate, and the cylindrical structure is formed by bending a second plate.

[0020] The installation method for the deck reinforcement structure, applied to the aforementioned deck reinforcement structure, includes the following steps:

[0021] S1. Connect and fix the annular structure to the cylindrical structure;

[0022] S2. The end face of the annular structure away from the cylindrical structure is brought into contact with the back of the deck;

[0023] S3. Connect the two axial ends of the ring structure to the crossbeam or the longitudinal beam, and connect the two axial ends of the cylindrical structure to the crossbeam or the longitudinal beam.

[0024] S4. Connect and fix the end face of the annular structure away from the cylindrical structure to the back of the deck, and connect and fix the two axial ends of the annular structure to the crossbeam or the longitudinal beam.

[0025] S5. Connect and fix the two axial ends of the cylindrical structure to the crossbeam or the longitudinal beam.

[0026] The beneficial effects of this invention are:

[0027] This invention provides a deck reinforcement structure. By connecting and fixing the end face of a ring-shaped structure to the back of the deck, and extending the radial ends of the ring-shaped structure outward along the extension direction of the deck and connecting and fixing them to the crossbeams or longitudinal beams, the connection and fixation between the deck and the crossbeams or longitudinal beams can be achieved, improving the structural strength of the deck directly opposite the winch base. By connecting and fixing a cylindrical structure to the end face of the ring-shaped structure away from the deck, and making the axis of the cylindrical structure perpendicular to the end face of the ring-shaped structure, the structural strength of the ring-shaped structure can be improved, further improving the structural strength of the deck directly opposite the winch base. By extending the radial ends of the cylindrical structure outward along the extension direction of the deck and connecting and fixing them to the crossbeams or longitudinal beams, the fixing effect between the ring-shaped structure and the deck and the crossbeams or longitudinal beams is further improved, thereby improving the structural strength of the deck directly opposite the winch base. Furthermore, since both radial ends of the ring structure and the cylindrical structure extend outward along the extension direction of the deck and are connected and fixed to the crossbeams or longitudinal beams, it not only improves the fixing effect between the deck and the crossbeams or longitudinal beams, but also allows the ring structure and cylindrical structure to be arranged away from the crossbeams or longitudinal beams during installation, providing space for the installation and fixing of the ring structure and cylindrical structure to the crossbeams or longitudinal beams, effectively reducing installation difficulty and improving installation efficiency.

[0028] This invention also provides an installation method for a deck reinforcement structure. By applying the aforementioned deck reinforcement structure, the structural strength of the deck directly opposite the winch base is effectively improved. Furthermore, since both radial ends of the annular structure and the cylindrical structure extend outwards along the deck's extension direction and are connected and fixed to the crossbeams or longitudinal beams, not only is the fixing effect between the deck and the crossbeams or longitudinal beams improved, but also, during the installation of the annular and cylindrical structures, they can be arranged away from the crossbeams or longitudinal beams, providing space for the installation and fixing of the annular and cylindrical structures to the crossbeams or longitudinal beams, effectively reducing installation difficulty and improving installation efficiency.

[0044] 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.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] 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.

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.

[0048] Example 1

[0049] This embodiment provides a ship winch, such as Figure 1 As shown, the ship's winch includes a cable drum, a winch base 500, and a power mechanism. The winch base 500 is mounted on the deck 200, the cable drum is rotatably mounted on the winch base 500, and the power mechanism is mounted on the back of the deck 200. The power mechanism is suspended below the cable drum via a main shaft and can drive the cable drum to rotate, thereby achieving the winding action of the rope. To ensure that the dynamic and static loads generated by the ship's winch do not damage the deck 200, a reasonable reinforcing structure needs to be installed in the area where the winch base 500 is located.

[0050] During ship design and construction, due to constraints such as processing procedures, reinforcement structures can only be installed and fixed after the main ship structure has been completed. In existing technologies, to ensure the strength of the reinforcement structure, extensive modifications to the original structure are required during installation. This results in limited construction space, difficulties in installation, and a waste of human and material resources.

[0051] To solve the above problems, such as Figures 2-5As shown, this embodiment provides a deck reinforcement structure 100. The deck reinforcement structure 100 includes an annular structure 110 and a cylindrical structure 120. The end face of the annular structure 110 is connected and fixed to the back surface of the deck 200. The radial ends of the annular structure 110 are arranged opposite to each other, extending outward along the extension direction of the deck 200 and connected and fixed to a crossbeam 300 or a longitudinal beam 400. The cylindrical structure 120 is connected and fixed to the end face of the annular structure 110 away from the deck 200. The axis of the cylindrical structure 120 is perpendicular to the end face of the annular structure 110. The radial ends of the cylindrical structure 120 are arranged opposite to each other, extending outward along the extension direction of the deck 200 and connected and fixed to a crossbeam 300 or a longitudinal beam 400.

[0052] The deck reinforcement structure 100 connects and fixes the end face of the annular structure 110 to the back of the deck 200, so that the radial ends of the annular structure 110 extend outward along the extension direction of the deck 200 and are connected and fixed to the crossbeam 300 or the longitudinal beam 400. This enables the connection and fixation of the deck 200 to the crossbeam 300 or the longitudinal beam 400, improving the structural strength of the deck 200 facing the winch base 500. By connecting and fixing the cylindrical structure 120 to the end face of the annular structure 110 away from the deck 200, the cylindrical structure 120... The axis of 20 is perpendicular to the end face of the ring structure 110, which can improve the structural strength of the ring structure 110 and further improve the structural strength of the deck 200 opposite to the winch base 500. By extending the radial ends of the cylindrical structure 120 outward along the extension direction of the deck 200 and connecting and fixing it with the crossbeam 300 or the longitudinal beam 400, the fixing effect of the ring structure 110 with the deck 200 and the crossbeam 300 or the longitudinal beam 400 is further improved, thereby improving the structural strength of the deck 200 opposite to the winch base 500. Furthermore, since both radial ends of the annular structure 110 and the cylindrical structure 120 extend outward along the extension direction of the deck 200 and are connected and fixed to the crossbeam 300 or the longitudinal beam 400, it not only improves the fixing effect between the deck 200 and the crossbeam 300 or the longitudinal beam 400, but also allows the annular structure 110 and the cylindrical structure 120 to be arranged away from the crossbeam 300 or the longitudinal beam 400 during the installation of the annular structure 110 and the cylindrical structure 120, providing space for the installation and fixing of the annular structure 110 and the cylindrical structure 120 to the crossbeam 300 or the longitudinal beam 400, effectively reducing the installation difficulty and improving the installation efficiency.

[0053] It should be noted that in this embodiment, both radial ends of the annular structure 110 and both radial ends of the cylindrical structure 120 are connected and fixed to the crossbeam 300. In other embodiments, both radial ends of the annular structure 110 and both radial ends of the cylindrical structure 120 can be connected and fixed to the longitudinal beam 400, or either one of the radial ends of the annular structure 110 and the cylindrical structure 120 can be connected and fixed to the crossbeam 300, and the other one can be connected and fixed to the longitudinal beam 400. This embodiment does not impose specific limitations. Furthermore, in this embodiment, the cylindrical structure 120 is welded and fixed to the end face of the annular structure 110 away from the deck 200, and both the annular structure 110 and the cylindrical structure 120 are connected and fixed to the crossbeam 300 by welding. Welding provides good fixing effect and high fixing efficiency.

[0054] Since the power mechanism in the ship's winch needs to be suspended below the cable drum via a main shaft, and the cable drum is mounted on the winch base 500, the first through hole 111 formed at the center of the annular structure 110 and the second through hole 121 formed at the center of the cylindrical structure 120 provide installation space for the power mechanism to ensure proper installation.

[0055] Specifically, the ring structure 110 is formed by cutting the first plate, and the cylindrical structure 120 is formed by bending the second plate, so as to select the most convenient forming method according to the different structural characteristics of the ring structure 110 and the cylindrical structure 120.

[0056] Furthermore, to further facilitate the welding and fixing of the annular structure 110 and the cylindrical structure 120 to the crossbeam 300, such as... Figure 5 As shown, a first gap 112 exists between the two radial ends of the annular structure 110, and a second gap 122 exists between the two radial ends of the cylindrical structure 120. By providing the first gap 112 between the two radial ends of the annular structure 110, the relative distance between the two radial ends of the annular structure 110 can be effectively increased, facilitating the welding and fixing of the radial ends of each annular structure 110. Similarly, by providing the second gap 122 between the two radial ends of the cylindrical structure 120, the relative distance between the two radial ends of the cylindrical structure 120 can be effectively increased, facilitating the welding and fixing of the radial ends of each cylindrical structure 120. It should be noted that in this embodiment, the first gap 112 and the second gap 122 are directly opposite each other, enabling continuous welding of the radial ends of the annular structure 110 and the cylindrical structure 120, thereby further improving the welding efficiency of the annular structure 110 and the cylindrical structure 120.

[0057] As an optional solution, the axial length of the cylindrical structure 120 is equal to the height of the crossbeam 300. By setting the axial length of the cylindrical structure 120 to be equal to the height of the crossbeam 300, when the cylindrical structure 120 is welded to the crossbeam 300, the cylindrical structure 120 is precisely welded to the crossbeam 300 along the entire axial direction. This not only improves the welding fixation effect but also reduces the size of the cylindrical structure 120, saving costs.

[0058] In an optional embodiment, the end face where the annular structure 110 is welded to the cylindrical structure 120 includes a first region 113 located inside the cylindrical structure 120 and a second region 114 located outside the cylindrical structure 120, wherein the area of ​​the first region 113 is larger than the area of ​​the second region 114. By making the area of ​​the first region 113 inside the cylindrical structure 120 on the end face of the annular structure 110 larger than the area of ​​the second region 114 outside the cylindrical structure 120, the size of the annular structure 110 extending outside the cylindrical structure 120 can be reduced, thereby further increasing the distance between the annular structure 110 and the crossbeam 300 and the longitudinal beam 400 while ensuring the structural strength of the annular structure 110 and the cylindrical structure 120.

[0059] Specifically, the difference between the outer diameter of the annular structure 110 and the outer diameter of the cylindrical structure 120 is 35mm to 45mm, and the inner diameter of the annular structure 110 only needs to accommodate the main shaft of the power mechanism. In this embodiment, the difference between the outer diameter of the annular structure 110 and the outer diameter of the cylindrical structure 120 is 40mm. In other embodiments, the difference between the outer diameter of the annular structure 110 and the outer diameter of the cylindrical structure 120 can be arbitrarily adjusted within the range of 35mm to 45mm according to actual needs; this embodiment does not impose a specific limitation.

[0060] Furthermore, the inner diameter of the cylindrical structure 120 is equal to the inner diameter of the winch base 500. By making the inner diameter of the cylindrical structure 120 equal to the inner diameter of the winch base 500, it is possible to ensure that the cylindrical wall of the cylindrical structure 120 is aligned with the seat wall of the winch base 500, thereby further improving the structural strength of the deck 200, which is aligned with the seat wall of the winch base 500.

[0061] As an optional solution, the deck reinforcement structure 100 further includes a first reinforcing member 130, wherein the first reinforcing member 130 is simultaneously connected and fixed to the outer wall of the cylindrical structure 120, the deck 200, and the crossbeam 300 or longitudinal beam 400. By providing the first reinforcing member 130, which is simultaneously connected and fixed to the outer wall of the cylindrical structure 120, the deck 200, and the crossbeam 300 or longitudinal beam 400, the connection stability between the deck 200 and the crossbeam 300 or longitudinal beam 400 can be further ensured, and the structural strength of the deck 200 can be improved. It should be noted that in this embodiment, the first reinforcing member 130 is an elbow plate, which is simultaneously welded and fixed to the outer wall of the cylindrical structure 120, the deck 200, and the crossbeam 300.

[0062] Specifically, the cylindrical structure 120 has elbow plates on its outer walls along both the transverse and longitudinal directions. Each elbow plate is simultaneously connected and fixed to the outer wall of the cylindrical structure 120, the deck 200, and the crossbeam 300 or longitudinal beam 400. By providing elbow plates on the outer walls of the cylindrical structure 120 along both the transverse and longitudinal directions, and ensuring that each elbow plate is simultaneously connected and fixed to the outer wall of the cylindrical structure 120, the deck 200, and the crossbeam 300 or longitudinal beam 400, the multiple elbow plates collectively enhance the structural strength of the deck 200.

[0063] In this embodiment, the deck reinforcement structure 100 further includes a second reinforcing member 140. The cylindrical structure 120 has second reinforcing members 140 on its outer walls along both the first and second directions. Each second reinforcing member 140 is simultaneously connected and fixed to both the outer wall of the cylindrical structure 120 and the deck 200. The first and second directions are perpendicular to each other, and the angle between the first and second directions is 45° and the angle between the second and second directions is also 45°. By providing second reinforcing members 140 on the outer walls of the cylindrical structure 120 along both the first and second directions, and ensuring that each second reinforcing member 140 is simultaneously connected and fixed to both the outer wall of the cylindrical structure 120 and the deck 200, the structural strength of the deck 200 can be further improved based on the addition of an elbow plate to enhance its structural strength. It should be noted that in this embodiment, the second reinforcing member 140 is a reinforcing rib.

[0064] Although the reinforcing rib has lower structural strength compared to the elbow plate, it requires less installation space and is easier to install. Furthermore, the load on the deck 200 is mainly lateral and longitudinal, with relatively small loads along the first and second directions, which the reinforcing rib can adequately meet. In other embodiments, the second reinforcing member 140 can also be an elbow plate; this embodiment does not impose a specific limitation.

[0065] Example 2

[0066] This embodiment provides a method for installing a deck reinforcement structure. For example... Figure 6As shown, the installation method of this deck reinforcement structure is applied to the deck reinforcement structure 100 provided in Embodiment 1 above. The installation method of this deck reinforcement structure includes the following steps:

[0067] S1. Connect and fix the annular structure 110 and the cylindrical structure 120;

[0068] S2. The end face of the annular structure 110 away from the cylindrical structure 120 abuts against the back of the deck 200;

[0069] S3. The two axial ends of the ring structure 110 abut against the crossbeam 300 or the longitudinal beam 400, and the two axial ends of the cylindrical structure 120 abut against the crossbeam 300 or the longitudinal beam 400.

[0070] S4. Connect and fix the end face of the annular structure 110 away from the cylindrical structure 120 to the back of the deck 200, and connect and fix the two axial ends of the annular structure 110 to the crossbeam 300 or the longitudinal beam 400.

[0071] S5. Connect and fix the two axial ends of the cylindrical structure 120 to the crossbeam 300 or the longitudinal beam 400.

[0072] The installation method of this deck reinforcement structure, by applying the aforementioned deck reinforcement structure 100, effectively improves the structural strength of the deck 200 directly opposite the winch base 500. Furthermore, since both radial ends of the annular structure 110 and the cylindrical structure 120 extend outwards along the extension direction of the deck 200 and are connected and fixed to the crossbeam 300 or longitudinal beam 400, this not only improves the fixing effect between the deck 200 and the crossbeam 300 or longitudinal beam 400, but also allows the annular structure 110 and cylindrical structure 120 to be arranged away from the crossbeam 300 or longitudinal beam 400 during installation. This provides space for the installation and fixing of the annular structure 110 and cylindrical structure 120 to the crossbeam 300 or longitudinal beam 400, effectively reducing installation difficulty and improving installation efficiency.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
