Description

Technical Field

[0001] The invention relates to the technical field of ships, in particular to a bridge wing structure. Background Art

[0002] The bridge wing is a place for people on board to observe. The current bridge wing is very prone to vibration, which seriously affects the comfort of people. The Chinese patent with the authorization announcement number CN214138846U discloses a horizontal diagonal brace anti-vibration device for reinforcing the bridge wing. Figure 3 It can be seen that the bridge wing is a cantilever structure extending out from the side wall of the upper building.

[0003] The existing bridge wing is mainly supported by a large bracket plate on the top of the next deck, which provides vertical support for the bridge wing. The superstructure of some ship types, especially container ships, is short and high, and the overall longitudinal vibration of the superstructure is severe. In order to ensure the lighting of the room under the bridge wing, holes are opened on the large bracket plate supporting the bridge wing, which further weakens the rigidity of the supporting structure and increases the risk of bridge wing vibration. Due to the reserved installation position of the desulfurization tower, some ships are arranged so that the upper structure ladder is arranged forward. In order to ensure the accessibility of the passage, it is necessary to open a passage on the lower supporting bracket plate, which brings more serious vibration problems, mainly to support the longitudinal vibration of the large bracket plate. Due to the existence of the ladder, the reinforcement of the bracket plate must avoid the ladder, so the bracket plate cannot be effectively supported at the next deck.

[0004] For container ships, the superstructure is short (in the direction of the ship's length) and high, which will bring about the longitudinal vibration problem of the superstructure. The bridge wing is the place where the ship's driving personnel watch during the ship's navigation. It is generally on the same level as the driving deck and is the same width as the ship. It is generally arranged in the front position of the superstructure. Some ships install main engine desulfurization towers in the superstructure area, so that the ladder is located forward, which will interfere with the position of the bridge wing. In order to ensure the continuity of the channel, it is necessary to open a channel on the bracket under the bridge wing, and the stiffness of the bracket is reduced, which will bring about the vibration problem of the bridge wing. The conventional solution is to add a large bracket between the two supporting brackets to increase the stiffness of the two supporting brackets along the length of the ship and reduce vibration. But the problem caused by this is that the added bracket will block the view and lighting of the windows under the bracket of the bridge wing. Summary of the invention

[0005] The purpose of the present invention is to provide a vibration-proof bridge wing structure to solve the problems existing in the prior art.

[0006] The object of the present invention is achieved as follows: An anti-vibration bridge wing structure is provided as a cantilever structure extending forward from the side wall of the superstructure. It includes a first structure body and a second structure body that are welded and fixed together and extend forward based on the side wall of the superstructure. The rear sides of the first structure body and the second structure body are both fixedly connected to the side wall of the superstructure. The first structure body is set as the main load-bearing part. The first structure body includes an upper panel, a pair of side panels, and a front panel. The upper panel is a flat panel. A pair of side panels are vertically fixed to the left and right sides of the lower surface of the upper panel and are parallel to each other. The front panel is vertically fixed to the front side of the upper panel, and the front panel is fixedly connected to the side panels.

[0007] The first structure body further includes a strengthening structure part. The strengthening structure part is located below the upper panel and between a pair of side panels. The strengthening structure part includes a strengthening panel and a number of reinforcing ribs. The strengthening panel and the reinforcing ribs each have at least one horizontal part and two side parts that are vertically and fixedly connected to the left and right sides of the horizontal part.

[0008] The horizontal part of the strengthening panel is fixedly joined to the front panel as a whole, and the two side parts of the strengthening panel are respectively fixedly connected to the two side panels.

[0009] All the reinforcing ribs are located behind the strengthening panel and are arranged at intervals in sequence from front to back. The horizontal part of the reinforcing rib is fixedly connected to the upper panel, and the two side parts of the reinforcing rib are respectively fixedly connected to the two side panels. The inner sides of the strengthening panel and the reinforcing ribs form a lighting space that penetrates from front to back.

[0010] The beneficial effects of the present invention are as follows:

[0011] The strengthening structure of this bridge wing structure can increase the vertical and longitudinal stiffness of the bridge wing support structure;

[0012] At the same time, since the inner sides of the strengthening panel and the reinforcing ribs form a lighting space that penetrates from front to back, it will not block the line of sight below and does not affect the lighting effect below. Description of the Drawings

[0020] Next, in combination with the attached Figures 1-7 drawings and specific embodiments, the present invention will be further described.

[0021] As Figures 1-7 shown, a vibration - proof bridge wing structure is provided as a cantilever structure extending forward from the superstructure side wall. It includes a first structure body 1 and a second structure body 2 which are welded and fixed together and extend forward based on the superstructure side wall. Both the rear sides of the first structure body 1 and the second structure body 2 are fixedly connected to the superstructure side wall. The first structure body 1 is set as the main load - bearing part and belongs to the main body part. The first structure body 1 includes an upper panel 11, a pair of side panels 12 and a front panel 13. The upper panel 11 is a flat plate. A pair of side panels 12 are vertically fixed to the left and right sides of the lower surface of the upper panel 11 and are parallel to each other. The front panel 13 is vertically fixed to the front side of the upper panel 11, and the front panel 13 is fixedly connected to the side panels 12.

[0022] The above - mentioned first structure body 1 further includes a strengthening structure part. The strengthening structure part is located below the upper panel 11 and between a pair of side panels 12. As Figure 2 、 7 shown, the strengthening structure part includes a strengthening panel 14 and a number of strengthening ribs 15. Both the strengthening panel 14 and the strengthening ribs 15 have a horizontal part and two side parts vertically and fixedly connected to the left and right sides of the horizontal part. A front - to - back through - hole is formed inside the strengthening panel 14 and the strengthening ribs 15.

[0023] The horizontal part of the above - mentioned strengthening panel 14 is fixedly joined with the front panel 13 as a whole. The two side parts of the strengthening panel 14 are respectively fixedly connected to the two side panels 12. The strengthening panel 14 can be set as a rectangular ring - shaped structure.

The horizontal part of the strengthening rib 15 is fixedly connected to the lower surface of the upper panel 11, and the two side parts of the strengthening rib 15 are respectively fixedly connected to the two side panels 12. The inside of the strengthening panel 14 and the strengthening ribs 15 are combined into a front - to - back through - hole lighting space 16 to facilitate ensuring the lighting effect of the lower windows.

[0025] With the above settings, the strengthening structure part of the first structure 1 can increase the vertical and longitudinal stiffness of the bridge wing support gusset while not blocking the window line of sight and daylighting, and at the same time has a certain aesthetic property.

[0026] To strengthen the structure of the reinforcing rib 15, as Figure 2 shown, the cross-sectional structure of the reinforcing rib 15 is T-shaped and is divided into two mutually perpendicular plate parts. One plate part of the reinforcing rib 15 is perpendicular to the upper panel 11 and the side panel 12, and the other plate part is at the inner edge of the reinforcing rib 15.

[0027] To strengthen the structural strength of the strengthening structure part of the first structure 1, the above-mentioned strengthening panel 14 is inclined backward based on the front panel 13, and the strengthening panel 14 is fixedly connected to the side parts of all or part of the reinforcing ribs 15.

[0028] To strengthen the structural strength and have an aesthetic effect, an arc chamfer is provided at the junction of the horizontal part and the side part of the above-mentioned reinforcing rib 15, and an arc chamfer is provided at the junction of the horizontal part and the side part of the strengthening panel 14.

[0029] The above-mentioned second structure 2 is an overall flat structure, and its projection shape is a right trapezoid, which can strengthen the structural strength of the entire bridge wing structure. The second structure 2 is composed of a horizontal support plate 21 and a plurality of lower reinforcing plates 22 fixedly connected below the support plate 21. The second structure 2 is seamlessly joined with the first structure 1 into a whole.
