Open cross-frame bridge wing structure

Abstract

The application provides an open cross-frame bridge wing structure, which is composed of a bridge wing top plate and a hollow support truss at the bottom of the bridge wing top plate. The support truss of the bridge wing structure is composed of an upper horizontal support truss, a lower horizontal support truss, a vertical support and a diagonal support frame, which are cross-connected to form an overall frame structure. This design significantly improves the overall rigidity of the bridge wing, effectively absorbs and disperses the vibration energy generated by the ship body, and avoids the influence caused by the ship body vibration. At the same time, all the support structures are open truss structures, which maximally reduce the weight of the structure, are beneficial to reduce the vibration of the bridge wing, and also ensure the openness of the view of the cabin near the bridge wing. In addition, the bridge wing structure has high durability and reliability. Due to the stability of the overall frame structure, the bridge wing can still maintain good performance and structural integrity under the influence of long-term load and environmental factors.

Description

Technical Field

[0001] This invention relates to ship design, specifically to an open cross-frame bridge wing structure. Background Technology

[0002] Bridge wings are outward extensions located on either side of the bridge deck, designed to facilitate observation and operation by the crew. When bridge wings extend excessively outward, they require adequate support to prevent vibrations that could compromise the ship's structural stability and crew safety. Since bridge wings are located outside cabin doors or windows, their design must ensure they do not obstruct the view of the cabin while also not hindering the opening of cabin doors.

[0003] While enclosed bridge wing structures can provide some support, they obstruct views of the cabin and increase structural weight. Using strut supports for the bridge wing would affect the overall structural layout and is not suitable for all vessels. Therefore, for designs with longer bridge wing lengths, this invention proposes an open cross-frame bridge wing structure. Summary of the Invention

[0004] This invention provides an open-type cross-frame bridge wing structure, which ensures structural rigidity and reduces bridge wing vibration. Simultaneously, compared to a closed bridge wing structure, it minimizes structural weight. Furthermore, this structure maintains unobstructed visibility within the cabin, without hindering cabin access or door opening. This structure, while ensuring bridge wing stability and safety, also fully considers the overall ship structure and the working needs of the crew. The specific solution is as follows:

[0005] An open cross-frame bridge wing structure is provided, wherein the open cross-frame bridge wing structure is symmetrically installed on both sides of the cabin, and the top of the cabin is provided with a cockpit. The open cross-frame bridge wing structure consists of a bridge wing top plate and a support truss with a hollowed-out bottom at the bridge wing top plate.

[0006] The bridge wing top plate is flush with the bridge deck, and a bulwark is installed on the edge of the bridge wing top plate. Several first elbow plates are connected between the bulwark and the bridge wing top plate.

[0007] The top of the support truss is provided with an upper horizontal support truss that is fixedly connected to the top plate of the bridge wing, and the bottom of the support truss is provided with a lower horizontal support truss that is fixedly connected to the cabin deck. Both the upper and lower horizontal support trusses are composed of intersecting transverse support plates and longitudinal support plates. The side of the upper and lower horizontal support trusses closest to the cabin is fixedly connected to the side wall of the cabin. Several vertical supports are connected between the upper and lower horizontal support trusses. The far end of the upper horizontal support truss away from the cabin is suspended on the cabin deck and the far end is connected to the lower horizontal support truss through an inclined support frame.

[0008] Furthermore, the upper horizontal support truss, the lower horizontal support truss, the vertical support, and the cabin sidewall are connected with beveled ribs, and the upper horizontal support truss, the lower horizontal support truss, and the inclined support frame are connected with beveled ribs.

[0009] Furthermore, the upper transverse support plate and upper longitudinal support plate of the upper horizontal support truss are both flat steel, and the lower transverse support plate and lower longitudinal support plate of the lower horizontal support truss are both square steel pipes; the vertical support is angle steel; and the inclined support frame is square steel pipe.

[0010] Furthermore, both the upper transverse support plate and the upper longitudinal support plate are vertically connected to a first vertical reinforcing rib plate, and the upper surface of the first vertical reinforcing rib plate is flush with the upper surface of the upper transverse support plate and the upper longitudinal support plate.

[0011] Furthermore, the lower surface of the inclined support frame located within the vertical projection area of ​​the bridge wing top plate is provided with a width extension plate.

[0012] Furthermore, the inner wall of the compartment side wall connected to the supporting truss is provided with several second vertical reinforcing ribs.

[0013] The bridge wing structure's supporting trusses consist of upper and lower horizontal supporting trusses, vertical supports, and diagonal support frames that intersect to form an integrated, intersecting frame structure. This design significantly improves the overall stiffness of the bridge wing and effectively absorbs and disperses the vibration energy generated by the hull, avoiding the impact of hull vibration. Simultaneously, all supporting structures are open truss structures, minimizing structural weight and reducing bridge wing vibration, while also ensuring unobstructed visibility in the cabins near the bridge wing. Furthermore, this bridge wing structure exhibits high durability and reliability. Due to the stability of its overall frame structure, the bridge wing maintains good performance and structural integrity even under long-term loads and environmental influences. In addition, the design of this bridge wing structure fully considers environmental protection and sustainable development. Its open truss structure simplifies and simplifies the construction process, reducing material waste and energy consumption. Attached Figure Description

[0027] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0028] To fully understand this invention, detailed steps and structures will be presented in the following description to illustrate the technical solution of this invention. Preferred embodiments of the invention are described in detail below; however, in addition to these detailed descriptions, the invention may have other embodiments.

[0029] This invention provides an open cross-frame bridge wing structure, which is symmetrically installed on both sides of a cabin 1, with a cockpit 2 located on the top of the cabin. The open cross-frame bridge wing structure consists of a bridge wing top plate 100 and a support truss 200 with a hollowed-out bottom portion located on the bridge wing top plate 100.

[0030] The bridge wing top plate 100 is flush with the bridge deck 21. A bulwark 110 is installed on the edge of the bridge wing top plate 100. Several first elbow plates 111 connect the bulwark 110 and the bridge wing top plate 100.

[0031] The top of the support truss 200 is provided with an upper horizontal support truss 210 that is fixedly connected to the bridge wing top plate 100, and the bottom of the support truss 200 is provided with a lower horizontal support truss 220 that is fixedly connected to the cabin deck. Both the upper horizontal support truss 210 and the lower horizontal support truss 220 are composed of transverse support plates and longitudinal support plates that are intersected. The side of the upper horizontal support truss 210 and the lower horizontal support truss 220 closest to the cabin 1 is fixedly connected to the cabin side wall 11 (i.e., the longitudinal bulkhead in the figure). Several vertical supports 230 are connected between the upper horizontal support truss 210 and the lower horizontal support truss 220. The far end of the upper horizontal support truss 210, away from the cabin, is suspended on the cabin deck and the far end is connected to the lower horizontal support truss 220 through an inclined support frame 240.

[0032] In an optional embodiment, beveled ribs 201 are connected to the joints of the upper horizontal support truss 210, the lower horizontal support truss 220 with the vertical support 230 and the cabin sidewall 11, and beveled ribs 201 are also connected to the joints of the upper horizontal support truss 210, the lower horizontal support truss 220 with the inclined support frame 240. The beveled ribs 201 are used to enhance the connection stability of the upper horizontal support truss 210, the lower horizontal support truss 220 with the vertical support 230, the cabin sidewall 11 and the inclined support frame 240.

[0033] In an optional embodiment, the upper transverse support plate 211 and upper longitudinal support plate 212 of the upper horizontal support truss 210 are both flat steel; the lower transverse support plate 221 and lower longitudinal support plate 222 of the lower horizontal support truss 220 are both square steel tubes; the vertical support 230 is angle steel; and the diagonal support frame 240 is square steel tube. Since the upper horizontal support truss 210 is suspended on the deck, its weight should be minimized while ensuring strength; therefore, the main material of the upper horizontal support truss 210 is flat steel. The lower horizontal support truss 220 is used to connect to the cabin deck and to bear the force of the upper horizontal support truss 210, vertical support 230, and diagonal support frame 240 and transfer it to the deck; therefore, it uses higher-strength square steel tubes. The vertical support 230 is used to vertically connect the upper horizontal support truss 210 and the lower horizontal support truss 220; flat steel is sufficient for weight reduction considerations. The inclined support frame 240 is used to connect the far end of the upper horizontal support truss 210, which requires higher strength, so higher strength square steel tubes are used here. Different parts of the support truss 200 use different types of steel, which reduces weight while ensuring overall strength, thus saving steel and reducing energy consumption.

[0034] Since the upper horizontal support truss 210 is used to support the bridge wing top plate 100, in order to further enhance the structural stability, the upper transverse support plate 211 and the upper longitudinal support plate 212 are both vertically connected with the first vertical reinforcing rib plate 213, and the upper surface of the first vertical reinforcing rib plate 213 is flush with the upper surface of the upper transverse support plate 211 and the upper longitudinal support plate 212.

[0035] Although the inclined support frame 240 uses higher strength square steel, in order to further improve its strength due to the oblique tensile stress it bears, a width extension plate 241 is provided on the lower surface of the inclined support frame 240 in the vertical projection area of ​​the bridge wing top plate 100. While improving the strength, the width extension plate 241 is only located in the area of ​​the support truss 200, making it more aesthetically pleasing.

[0036] Since the sidewall 11 of the compartment also needs to bear the stress of the bridge wing structure, it is necessary to carry out structural reinforcement design to improve its strength and prevent deformation of the sidewall 11 of the compartment. As shown in the figure, the inner wall of the sidewall 11 of the compartment connected to the supporting truss 200 is provided with several second vertical reinforcing ribs 13 to strengthen the sidewall 11 of the compartment.

[0037] In conclusion, the open cross-frame bridge wing structure is an innovative and practical design that effectively solves the problems faced by closed bridge wing structures. It ensures bridge wing rigidity, reduces wing vibration, minimizes structural weight, and maintains unobstructed cabin visibility. This design is of great significance for improving the overall stability of the ship.
