Description

Technical Field

[0001] The utility model relates to a ship support structure, in particular to a rescue boat deck support structure and a ship. Background Art

[0002] In the design of certain types of ships, especially when a pilot ladder is arranged near the superstructure area at the stern, the side rescue boat and its raft frame cannot be directly arranged above the main deck. Therefore, a special deck, that is, a rescue boat deck, needs to be set in these areas. The rescue boat deck is generally arranged on the outer edge side of the main deck to install and operate equipment such as the side rescue boat and its raft frame.

[0003] The currently common rescue boat deck support structure usually adopts longitudinal support members such as vertically upward circular columns and rectangular steel plates. By setting longitudinal support structures between the main deck and the rescue boat deck, the rescue boat deck is fixedly connected to the main deck. Although this structure provides strong support in the vertical direction, its support capacity in the ship length direction and ship width direction is relatively weak. Due to the insufficient overall stiffness of the boat deck structure, especially the low stiffness in the ship length direction and ship width direction, the boat deck is prone to vibration problems. This will not only affect the safety and efficiency of rescue operations, but may also cause problems in terms of structural strength, such as fatigue damage, etc.

[0004] Therefore, developing a new boat deck support structure has become an urgent technical problem for those skilled in the art. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the defect that the support capacity of the boat deck support structure in the ship length and width directions in the prior art is weak, and to provide a rescue boat deck support structure with a simple structure, which improves the stiffness and strength in the ship length direction and ship width direction.

[0006] The utility model solves the above technical problem through the following technical solutions:

[0007] A rescue boat deck support structure, which includes: a rescue boat deck, a main deck, and a support structure. The support structure includes longitudinal support members and a quadrilateral box structure. The quadrilateral box structure is located between the main deck and the rescue boat deck, and both ends of the quadrilateral box structure are welded to the main deck and the rescue boat deck respectively;

[0008] There are boat facility columns on the rescue boat deck. The area of the end face of the quadrilateral box structure connected to the rescue boat deck is not less than the area of the end face of the boat facility column connected to the rescue boat deck, and the area of the end face of the quadrilateral box structure connected to the main deck is greater than the area of the end face of the quadrilateral box structure connected to the rescue boat deck.

[0009] In this solution, in the support structure between the main deck and the rescue boat deck, in addition to the longitudinal support members generally provided to provide vertical support force, a quadrilateral box structure is added to provide more support force in the length and width directions of the hull. Above the rescue boat deck, there are boat facility columns for supporting the weight of the facilities on the rescue boat deck. By ensuring that the contact area between the quadrilateral box structure and the rescue boat deck is not less than that of the boat facility columns, it is ensured that the quadrilateral box structure can provide sufficient vertical support force. And making the end face area where the quadrilateral box structure is connected to the main deck larger than the end face area where it is connected to the rescue boat deck is to form a shape that is wider at the bottom than at the top, providing more support force in the length and width directions of the hull compared to the existing longitudinal support members with the same width at the top and bottom.

[0010] Among them, the end face area refers to the area enclosed by the overall contour of the part welded to the quadrilateral box structure.

[0011] Preferably, the quadrilateral box structure is located directly below the boat facility columns.

[0012] In this solution, since the main weight of the rescue boat facilities is concentrated on the boat facility columns, by arranging the quadrilateral box structure directly below the boat facility columns, the strengthening effect on the support is maximized, making the overall structure more stable and reasonable.

[0013] Preferably, the quadrilateral box structure is a quadrilateral hollow structure formed by welding four side plates in pairs.

[0014] In this solution, the quadrilateral box structure is a quadrilateral hollow structure formed by welding four side plates in pairs. On the one hand, the overall economy is better and the processability is easier to implement. On the other hand, necessary pipelines and pipe equipment on the ship can also be arranged inside the box, improving the space utilization rate.

[0015] Preferably, at least one weight reduction hole is provided on each side wall of the quadrilateral box structure.

[0016] In this solution, by setting weight reduction holes on the side walls of the quadrilateral box structure, the weight of the overall box structure is reduced, the material cost is saved, the overall weight is controlled, and the structural efficiency is improved.

[0017] Preferably, the weight reduction holes are oval, and the weight reduction holes on one side wall are arranged opposite to the weight reduction holes on the opposite side wall.

[0018] In this solution, the weight reduction holes are made oval because oval holes can better disperse stress and make the stress distribution more uniform compared to holes of other shapes; arranging the weight reduction holes opposite to each other enables the installation and layout of ship pipelines, pipe lines and other equipment through the weight reduction holes, improving the utilization rate of the structure and optimizing the facility planning of the ship.

[0019] Preferably, a strip-like structure is provided around the weight-reducing hole for strengthening the strength of the quadrilateral box structure.

[0020] In this solution, around the weight-reducing holes provided on the side walls of the quadrilateral box structure, including positions such as the sides, above, and below, strip-like structures are provided to reinforce the overall structure. They can increase the stiffness of local areas, reduce the structural deformation caused by opening the weight-reducing holes, and increase the overall stability of the weight-reducing hole area. The material of the strip-like structure can be steel consistent with the support structure, and the strip-like setting is considered for the easy implementation of the steel processing technology.

[0021] The setting method is to set one or more circles of strips around the weight-reducing hole to form a frame structure. When multiple weight-reducing holes are arranged along the length direction of the side wall, the strips can be arranged along the setting direction of the weight-reducing holes. In addition, the strips can also be arranged crosswise around the weight-reducing hole to form a grid-like reinforcing structure.

[0022] Preferably, reinforcing ribs are provided on the side wall of the longitudinal support member, and both ends of the reinforcing ribs are fixedly connected to the main deck and the rescue boat deck respectively.

[0023] In this solution, by providing reinforcing ribs on the side wall of the longitudinal support member, the structural strength of the longitudinal support member is strengthened. By fixedly connecting both ends of the reinforcing ribs to the main deck and the rescue boat deck respectively, the supporting force given in the vertical direction of the longitudinal support member is further enhanced.

[0024] Preferably, reinforcing ribs are provided between the side wall of the longitudinal support member and the main deck, and reinforcing ribs are provided between the side wall of the longitudinal support member and the rescue boat deck.

[0025] In this solution, by providing reinforcing ribs between the longitudinal support member and the main deck, the supporting force and the structural strength and stability of the longitudinal support member in the direction of the reinforcing ribs are enhanced.

[0026] Preferably, the longitudinal support member further includes an elliptical columnar upright provided at one end of the main deck close to the bow, and both ends of the elliptical columnar upright are welded to the main deck and the rescue boat deck respectively.

[0027] In this solution, an elliptical columnar upright is provided at one end of the main deck close to the bow, which can disperse the stress received by the support structure. Considering the balance of structural strength, the elliptical columnar upright has a high flexural strength and torsional stiffness. By arranging the elliptical columnar upright at one end of the main deck close to the bow as a reinforcement of the support structure, the supporting force distribution of the overall deck is made more uniform and stable.

[0028] On the other hand, the present utility model adopts the following technical solutions:

[0029] A ship, which includes the rescue boat deck support structure as described above.

[0030] The positive and progressive effects of the present utility model are as follows: By adding a quadrilateral box structure to the support structure between the main deck and the rescue boat deck, more support forces in the length and width directions of the hull are provided. There are boat facility columns above the rescue boat deck for supporting the weight of the facilities on the rescue boat deck. By ensuring that the contact area between the quadrilateral box structure and the rescue boat deck is not less than that of the boat facility columns, it is guaranteed that the quadrilateral box structure can provide sufficient vertical support force. And making the end face area where the quadrilateral box structure is connected to the main deck larger than the end face area where it is connected to the rescue boat deck is to form a shape that is wider at the bottom than at the top, providing more support forces in the length and width directions of the hull compared to the existing longitudinal support members with the same width at the top and bottom. Among them, the end face area refers to the area enclosed by the overall contour of the part welded to the quadrilateral box structure. Description of the Drawings

[0052] The present utility model will be further described below by way of embodiments, and will be more clearly and completely described in conjunction with the accompanying drawings, but the present utility model is not limited to the scope of the embodiments thereby.

[0053] As Figures 1 - 8 shown, in this embodiment, a support structure for a rescue boat deck is provided. The support structure for the rescue boat deck includes: a rescue boat deck 20, a main deck 10, and a support structure 15. The support structure 15 includes a longitudinal support member 110 and a quadrilateral box structure 120. The quadrilateral box structure 120 is located between the main deck 10 and the rescue boat deck 20, and both ends of the quadrilateral box structure 120 are welded to the main deck 10 and the rescue boat deck 20 respectively. There is a column 21 for boat facilities on the rescue boat deck 20. The area of the end face of the quadrilateral box structure 120 connected to the rescue boat deck 20 is not less than the area of the end face where the column 21 for boat facilities is connected to the rescue boat deck 20, and the area of the end face of the quadrilateral box structure 120 connected to the main deck 10 is greater than the area of the end face of the quadrilateral box structure 120 connected to the rescue boat deck 20.

[0054] In the above-described embodiment, in the support structure 15 between the main deck 10 and the rescue boat deck 20, in addition to the generally provided longitudinal support member 110 for providing vertical support force, a quadrilateral box structure 120 is added to provide more support force in the length and width directions of the hull. Above the rescue boat deck 20, there are boat facility columns 21 for supporting the weight of the facilities on the rescue boat deck 20. By making the contact area between the quadrilateral box structure 120 and the rescue boat deck 20 not less than that of the boat facility columns 21, it is ensured that the quadrilateral box structure 120 can provide sufficient vertical support force. And making the end face area where the quadrilateral box structure 120 is connected to the main deck 10 larger than the end face area where it is connected to the rescue boat deck 20 is to form a shape with a wider bottom than the top, providing more support force in the length and width directions of the hull compared to the existing longitudinal support member 110 with the same width at the top and bottom. Herein, the end face area refers to the area enclosed by the overall contour of the part welded to the quadrilateral box structure 120.

[0055] As Figure 1 and Figure 2 shown, the quadrilateral box structure 120 is located directly below the boat facility columns 21.

[0056] In the above-described embodiment, since the main weight of the rescue boat facilities is concentrated on the boat facility columns 21, by arranging the quadrilateral box structure 120 directly below the boat facility columns 21, the strengthening effect on the support is maximized, making the overall structure more stable and reasonable. Those skilled in the art can also adjust the position of the quadrilateral box structure 120 according to actual design needs. If it is not located directly below the boat facility columns 21, it can also achieve the effect of providing more support force in the length and width directions of the hull, but the stability and support effect of the overall structure are not as good as this solution.

[0057] As Figure 1 and 2 shown, the quadrilateral box structure 120 is a quadrilateral hollow structure formed by welding two pairs of four side plates.

[0058] In the above-described embodiment, the quadrilateral box structure 120 is a quadrilateral hollow structure formed by welding two pairs of four side plates. On the one hand, the overall economy is better and the processability is easier to implement. On the other hand, necessary pipelines and pipe equipment in the ship can also be arranged inside the box, improving the space utilization rate. When the quadrilateral box structure 120 is a solid structure, it can also provide more support force in the length and width directions of the hull. Relatively speaking, it is more difficult to process and implement in terms of technology, the cost is higher, and there is no available internal space, resulting in low space utilization rate.

[0059] As Figure 2 、 Figure 4 、 Figure 7 and Figure 8As shown, at least one weight-reducing hole 121 is provided on each side wall of the quadrilateral box structure 120. By providing the weight-reducing holes 121 on the side walls of the quadrilateral box structure 120, the weight of the overall box structure is reduced, the material cost is saved, the overall weight is controlled, and the structural efficiency is improved. Those skilled in the art can select the reasonable positions and numbers of the weight-reducing holes 121 on the side walls according to actual design requirements. If the weight-reducing holes 121 are not selected to be provided, the quadrilateral box structure 120 can also provide more supporting forces in the length and width directions of the hull.

[0060] As Figure 2 shown, the weight-reducing hole 121 is oval, and the weight-reducing holes 121 on one side wall are arranged opposite to those on the opposite side wall. The weight-reducing hole 121 is made oval because the oval hole can disperse stress better than holes of other shapes, making the stress distribution more uniform; the weight-reducing holes 121 are arranged oppositely so that equipment such as ship pipelines and pipelines can be arranged and laid out through the weight-reducing holes 121, improving the utilization rate of the structure and optimizing the facility planning of the ship. Those skilled in the art can select weight-reducing holes 121 of other shapes according to actual needs, but stress unevenness is more likely to occur in other shapes compared to the oval shape; according to the actual needs of arranging ship pipelines and pipelines and other equipment, the weight-reducing holes 121 can also be arranged in a manner other than the opposite arrangement.

[0061] As Figure 2 shown, a strip-shaped structure 122 is provided around the weight-reducing hole 121 to strengthen the strength of the quadrilateral box structure 120. By providing the strip-shaped structure 122 around the weight-reducing holes 121 provided on the side walls of the quadrilateral box structure 120, including positions such as the sides, above, and below, the overall structure is reinforced. They can increase the stiffness of the local area, reduce the structural deformation caused by the opening of the weight-reducing holes 121, and increase the overall stability of the weight-reducing hole 121 area. The material of the strip-shaped structure 122 can be the same steel as the support structure 15, and it is set as a strip shape for the consideration of facilitating the implementation of the steel processing technology. Those skilled in the art can determine the specific number and form of the structure according to actual needs to reinforce the overall stability of the quadrilateral box structure 120. If not provided, it does not affect the supporting forces provided by the quadrilateral box structure 120 in the length and width directions of the hull. The setting method is to set one or more circles of strips around the weight-reducing hole 121 to form a frame structure. When multiple weight-reducing holes 121 are arranged in a row along the length direction of the side wall, the strips can be arranged along the setting direction of the weight-reducing holes 121. In addition, the strips can also be arranged crosswise around the weight-reducing holes 121 to form a grid-shaped reinforcement structure.

[0062] As Figure 1 shown, reinforcing ribs 111 are provided on the side walls of the longitudinal support member 110, and both ends of the reinforcing ribs 111 are fixedly connected to the main deck 10 and the rescue boat deck 20 respectively.

[0063] In the above-described embodiment, by providing reinforcing ribs 111 on the side wall of the longitudinal support member 110, the structural strength of the longitudinal support member 110 is strengthened. By fixedly connecting both ends of the reinforcing ribs 111 to the main deck 10 and the rescue boat deck 20 respectively, the supporting force provided by the longitudinal support member 110 in the vertical direction is further enhanced. The specific form and number of the reinforcing ribs 111 can be determined by those skilled in the art according to actual needs. If the reinforcing ribs 111 are not provided, it does not affect the longitudinal supporting function provided by the longitudinal support member 110 itself.

[0064] As Figure 5 and Figure 6 shown, reinforcing ribs 112 are provided between the side wall of the longitudinal support member 110 and the main deck 10, and reinforcing ribs 112 are provided between the side wall of the longitudinal support member 110 and the rescue boat deck 20.

[0065] In the above-described embodiment, by providing the reinforcing ribs 112 between the longitudinal support member 110 and the main deck 10, the supporting force and the structural strength and stability of the longitudinal support member 110 in the direction of the reinforcing ribs 112 are enhanced. The specific form and number of the reinforcing ribs 112 can be determined by those skilled in the art according to actual needs. If the reinforcing ribs 112 are not provided, the structural strength and stability of the longitudinal support member 110 in the direction of the reinforcing ribs 112 cannot be improved, but it does not affect the longitudinal supporting function provided by the longitudinal support member 110 itself.

[0066] As Figure 1 and Figure 4 shown, the longitudinal support member 110 further includes an elliptical columnar upright 113 provided at one end of the main deck 10 near the bow, and both ends of the elliptical columnar upright 113 are welded to the main deck 10 and the rescue boat deck 20 respectively.

[0067] In the above-described embodiment, by providing the elliptical columnar upright 113 at one end of the main deck 10 near the bow, the stress received by the support structure 15 can be dispersed. Considering the balance of structural strength, the elliptical columnar upright 113 has a high flexural strength and torsional stiffness. By arranging the elliptical columnar upright 113 at one end of the main deck 10 near the bow as a reinforcement of the support structure 15, the supporting force distribution of the overall deck is made more uniform and stable. The specific form and number of the uprights can be determined by those skilled in the art according to actual needs.

[0068] This embodiment also provides a ship, which includes the rescue boat deck support structure as described above.

[0069] Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that this is only an example, and the protection scope of the present invention is defined by the appended claims. Without departing from the principle and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
