Description

Technical Field

[0001] The utility model relates to the field of shipbuilding, in particular to a support node for the front leg of a davit. Background Art

[0002] There is a Chinese utility model patent with the publication number CN201429510Y and the name of "A device for completing the dropping test of a throw-down lifeboat by using an external manual release". Combining the disclosed specification drawings, it can be seen that the throw-down lifeboat davit is installed at the stern of the ship, and the front leg of the throw-down lifeboat davit is directly installed on the deck next to the stern seal plate. However, when the main dimensions of the ship are relatively small (similar to small and medium-sized chemical tankers), the front leg of the throw-down lifeboat davit will occupy a certain space, affecting the arrangement of mooring components on the stern deck. Content of the Utility Model

[0003] The purpose of the utility model is to provide a support node for the front leg of a davit that occupies less space and is convenient for arranging mooring components on the stern deck in view of the deficiencies of the existing technology.

[0004] To achieve the above purpose, the technical solution adopted by the support node of the front leg of the davit of the utility model is as follows:

[0005] A support node for the front leg of a davit includes a stern seal plate and a deck. A support plate for supporting the front leg of the davit is provided at the top of the stern seal plate, and the support plate protrudes towards the deck side. At least one first stiffening rib plate is provided above the deck for supporting the support plate, and at least one second stiffening rib plate corresponding to the position of the first stiffening rib plate is provided between the bottom surface of the deck and the side wall of the stern seal plate.

[0006] Preferably, the number of both the first stiffening rib plate and the second stiffening rib plate is one, and the center lines of the first and second stiffening rib plates are aligned with the center line of the front leg of the davit at the same time.

[0007] Preferably, the number of both the first stiffening rib plate and the second stiffening rib plate is two. The two first stiffening rib plates are symmetric about the center line of the front leg of the davit, and the second stiffening rib plate and the lower ends of the first stiffening rib plates are in the same vertical plane.

[0008] Preferably, the included angle between the first stiffening rib plate and the deck is 60 - 90°.

[0009] Preferably, the number of the first stiffening rib plates is two, and the number of the second stiffening rib plates is one. The two first stiffening rib plates are respectively on both sides of the center line of the front leg of the davit, and there is a clearance space between one of the first stiffening rib plates and the top surface of the deck. The second stiffening rib plate and the other first stiffening rib plate are in the same vertical plane.

[0010] Compared with the existing technology, the utility model has the following advantages:

[0011] The front leg of the davit rests on the supporting plate at the top of the stern sealing plate, without occupying the space of the stern deck. The first reinforcing rib plate for supporting the supporting plate can be adjusted in terms of quantity and position as needed to facilitate the arrangement of mooring components.

[0019] Embodiment 1, as Figures 1-3 shown, a supporting node of the front leg of a davit includes a stern sealing plate 1 and a deck 2. A supporting plate 4 for supporting the front leg 3 of the davit is welded to the top of the stern sealing plate. The supporting plate protrudes towards the deck side. A first reinforcing rib plate 5 is arranged above the deck for supporting the supporting plate. A second reinforcing rib plate 6 is arranged between the bottom surface of the deck and the side wall of the stern sealing plate. The number of both the first reinforcing rib plate and the second reinforcing rib plate is one. The center lines of the first and second reinforcing rib plates are aligned with the center line of the front leg of the davit at the same time. The top surface of the first reinforcing rib plate is welded to the bottom surface of the supporting plate, the bottom surface is welded to the top surface of the deck, and the side wall is welded to the side wall of the stern sealing plate. The top surface of the second reinforcing rib plate is welded to the bottom surface of the deck, and the side wall is welded to the side wall of the stern sealing plate.

[0020] Embodiment 2, as Figure 1 , 4, as shown in FIGS. 5, a support node of the front leg of a davit, comprising a stern sealing plate 1 and a deck 2. A support plate 4 for supporting the front leg 3 of the davit is welded to the top of the stern sealing plate, and the support plate protrudes towards the deck side. A first stiffening rib plate 5 is arranged above the deck for supporting the support plate. A second stiffening rib plate 6 is arranged between the bottom surface of the deck and the side wall of the stern sealing plate. The number of both the first stiffening rib plate and the second stiffening rib plate is two. The two first stiffening rib plates are symmetric about the center line of the front leg of the davit. The included angle between the first stiffening rib plate and the deck is 79°. The lower end of the second stiffening rib plate and the first stiffening rib plate are in the same vertical plane. The top surface of the first stiffening rib plate is welded to the bottom surface of the support plate, the bottom surface is welded to the top surface of the deck, and the side wall is welded to the side wall of the stern sealing plate. The top surface of the second stiffening rib plate is welded to the bottom surface of the deck, and the side wall is welded to the side wall of the stern sealing plate.

[0021] Embodiment 3, as Figure 1 , 4 , as shown in FIGS. 5, a support node of the front leg of a davit, comprising a stern sealing plate 1 and a deck 2. A support plate 4 for supporting the front leg 3 of the davit is welded to the top of the stern sealing plate, and the support plate protrudes towards the deck side. A first stiffening rib plate 5 is arranged above the deck for supporting the support plate. A second stiffening rib plate 6 is arranged between the bottom surface of the deck and the side wall of the stern sealing plate. The number of the first stiffening rib plate is two, and the number of the second stiffening rib plate is one. The two first stiffening rib plates are respectively on both sides of the center line of the front leg of the davit.
