Abstract
Description
Technical Field
[0001] This utility model relates to the field of shipbuilding technology, specifically to a tooling for launching ship airbags. Background Technology
[0002] Airbag launching is a common method for launching ships from the slipway. However, during airbag launching, if there are unfavorable factors such as significant changes in the bow's shape, a large bow weight, or shallow water near the end of the slipway, the bow may fall (slamming into the slipway). Since the bow of most ships houses important equipment such as propellers, a bow fall can cause structural damage and damage to critical equipment, leading to significant losses for the ship. Utility Model Content
[0003] In view of this, the present invention provides a tooling for launching ship airbags, which can prevent the bow of the ship from colliding with the slipway.
[0004] To solve at least one of the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A tooling for launching ship airbags according to an embodiment of the present invention includes:
[0006] A bottom plate, which is used to be placed on a slipway and located below the bow side of the vessel, with one end of the bottom plate extending out of the bow along the length of the vessel.
[0007] The support structure has one end connected to the bottom plate and the other end used to connect to the bow of the ship.
[0008] In one embodiment of this utility model, a base plate reinforcement structure is provided on the base plate.
[0009] In one embodiment of this utility model, the base plate reinforcement structure includes:
[0010] Multiple first reinforcing plates are spaced apart along a first direction and perpendicular to the base plate. Each first reinforcing plate extends along a second direction and has multiple slots spaced apart along the second direction.
[0011] Multiple second reinforcing plates are spaced apart along a second direction, each second reinforcing plate extends along a first direction, and each second reinforcing plate is inserted into its corresponding slot along the first direction and connected to the multiple first reinforcing plates respectively.
[0012] The first direction is perpendicular to the second direction, and both the first and second directions are perpendicular to the vertical direction.
[0013] In one embodiment of this utility model, each first reinforcing plate and each second reinforcing plate are respectively provided with a reinforcing panel.
[0014] In one embodiment of this utility model, the support structure includes multiple support members, one end of each support member is connected to the bottom plate reinforcement structure and the bottom plate respectively, and the other end of each support member is connected to the bow of the ship.
[0015] In one embodiment of this utility model, the end of the support member near the base plate is connected to the first reinforcing plate and / or the second reinforcing plate.
[0016] In one embodiment of this utility model, each support member is provided with a connecting plate on its top for connection with the bow of a ship.
[0017] In one embodiment of this utility model, the tooling for launching ship airbags further includes:
[0018] Multiple reinforcing elbows are installed on the inner wall of the bow of the ship, and each reinforcing elbow is respectively installed with its corresponding support member at the end closest to the ship.
[0019] In one embodiment of this utility model, a plurality of drainage holes are provided on the base plate in a vertical direction.
[0020] The above-mentioned technical solution of this utility model has at least one of the following beneficial effects:
[0021] This utility model discloses a tooling for launching ships with airbags. By using a supporting structure to connect the bottom plate and the bow of the ship, during the airbag launching process on the slipway, two sets of tooling are connected to the lower sides of both sides of the bow. The bottom of the ship and the two sets of tooling are placed on the airbags. When the bottom plate of the bow reaches the end of the slipway, the airbags under the tooling do not immediately detach under the support of the tooling, allowing the airbags to continue bearing the weight of the bow and move into the water with the ship. Furthermore, because the end of the tooling's bottom plate, furthest from the bottom of the ship, extends along the length of the ship beyond the bow, when the foremost part of the bottom plate reaches the end of the slipway, the airbags under the tooling can still support the bow, thus preventing the bow from colliding with the slipway and improving the safety of launching ships with airbags.

Detailed Implementation
[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0030] To facilitate understanding of the technical solution of this utility model, the technical problem to be solved by this utility model will be explained first.
[0031] like Figure 1 and Figure 2 As shown, when launching a ship using the airbag 300 method, the ship is first placed on the slipway 100 with its bow 200 facing away from the end of the slipway. Multiple airbags 300 are placed under the bottom of the ship on both sides. However, due to the significant change in the shape of the bottom plate 400 of the bow 200, when the airbags 300 roll to the point of change in the bow shape, they will gradually detach from the bottom of the ship. The airbags 300 will then lose their load-bearing function. If the water depth at the end of the slipway 100 is insufficient to float the bow 200, causing it to detach from the slipway 100, the bow 200 will fall and hit the slipway 100, resulting in damage to the structure and important equipment.
[0032] To solve the above-mentioned technical problems, this utility model provides a tooling for launching ship airbags.
[0033] The following is a detailed description, with reference to the accompanying drawings, of a tooling for launching a ship's airbag according to an embodiment of the present invention.
[0034] like Figure 3 and Figure 4 As shown, the tooling for launching ship airbags according to this embodiment of the present invention may include: a base plate 400 and a support structure 500. The base plate 400 is placed on the slipway 100 and is located below the bow section 200 of the ship. One end of the base plate 400, away from the bottom of the ship, extends outward along the length of the ship beyond the bow section 200. One end of the support structure 500 is connected to the base plate 400, and the other end of the support structure 500 is connected to the bow section 200 of the ship.
[0035] In one possible embodiment, the ship airbag launching fixtures of this invention can be respectively installed below both sides of the bow 200 of the ship. Each fixture is connected to the base plate 400 and the bow 200 of the ship via a support structure 500. During the launching of the ship airbags on the slipway, the base plates 400 of the two fixtures are placed on the airbags 300 respectively. When the change in the shape of the base plate of the bow 200 reaches the end of the slipway 100, the base plate 400 will always be located below one side of the bow 200. Under the support of the fixtures, the airbags 300 below the base plate 400 will not immediately detach, so that the airbags 300 still bear the weight of the bow 200 and move into the water with the ship. Furthermore, when the foremost end of the ship's bottom plate reaches the end of the slipway 100, that is, when the ship is about to enter the water, since the end of the tooling bottom plate 400 away from the bottom of the ship extends along the length of the ship to the bow 200, the airbag 300 under the bottom plate 400 can still support the bow 200, thereby preventing the bow 200 from colliding with the slipway 100 and improving the safety of the ship when the airbag is launched.
[0036] like Figure 5 and Figure 6 As shown, a base plate 400 is provided with a base plate reinforcing structure 410, which may include: a plurality of first reinforcing plates 411 and a plurality of second reinforcing plates 412. The plurality of first reinforcing plates 411 are spaced apart along a first direction and perpendicular to the base plate 400, each first reinforcing plate 411 extends along a second direction, and each first reinforcing plate 411 has a plurality of slots spaced apart along the second direction; the plurality of second reinforcing plates 412 are spaced apart along the second direction, each second reinforcing plate 412 extends along the first direction, and each second reinforcing plate 412 is inserted into its corresponding slot along the first direction and connected to the plurality of first reinforcing plates 411; the first direction is perpendicular to the second direction, and both the first and second directions are perpendicular to the vertical direction.
[0037] In this embodiment, multiple first reinforcing plates 411 are perpendicularly arranged to the base plate 400 and spaced apart along the first direction to form multiple transverse reinforcing members, thereby effectively improving the bending stiffness of the base plate 400 in the second direction. Multiple slots on each first reinforcing plate 411 are used to accommodate second reinforcing plates 412, allowing the second reinforcing plates 412 to laterally penetrate multiple first reinforcing plates 411 along the second direction, forming a grid-like base plate reinforcing structure 410 that interlocks with the first reinforcing plates 411. After the multiple second reinforcing plates 412 are inserted into their corresponding slots, they further extend along the first direction and connect with their respective first reinforcing plates 411, achieving overall interlocking of the structure and enhancing the spatial stability and torsional stiffness of the base plate 400 when the ship is supported by the airbag 300.
[0038] like Figure 5 and Figure 6 As shown, each first reinforcing plate 411 and each second reinforcing plate 412 is provided with an upwardly extending reinforcing panel, which can be integrally formed with the first reinforcing plate 411 or the second reinforcing plate 412, respectively. Therefore, the strength of the first reinforcing plate 411 and the second reinforcing plate 412 can be further improved without affecting the assembly between the plates.
[0039] like Figure 5 As shown, the bottom plate 400 is provided with multiple vertically penetrating drainage holes 420. Thus, when water accumulates in the grid formed by the interlocking of the second reinforcing plate 412 and the first reinforcing plate 411 on the bottom plate 400, the water can be quickly drained through the drainage holes 420, which can reduce the overall weight of the tooling, reduce the draft of the bow of the ship, and prevent the bottom plate 400, the second reinforcing plate 412, or the first reinforcing plate 411 from rusting.
[0040] like Figure 6 As shown, the support structure 500 includes multiple support members. One end of each support member is connected to the bottom plate reinforcement structure 410 and the bottom plate 400, respectively, and the other end of each support member is connected to the bow section 200 of the ship. In this embodiment, the support members can be steel pipes, square steel, I-beams, or other forms of support structure 500. Furthermore, the support members can be connected in pairs according to the shape characteristics of the bow section 200 of the ship, or multiple support members can be connected by cross braces; this application does not impose any limitations. Therefore, the support strength of the support members can be effectively improved.
[0041] like Figure 5 and Figure 6As shown, one end of the support member near the base plate 400 is connected to the first reinforcing plate 411 and / or the second reinforcing plate 412. In this embodiment, by connecting the support member to the first reinforcing plate 411 and / or the second reinforcing plate 412 respectively, a stable multi-point connection structure can be formed. This not only improves the installation rigidity of the support member and prevents displacement or deformation under load, but also effectively transfers the load from the support member to the base plate 400, further improving the load-bearing capacity and stability of the structure.
[0042] Figure 6 As shown, each support member has a connecting plate 501 on its top for connecting to the bow section 200 of the vessel. The connecting plate 501 can be an elbow plate or a pad. By providing the connecting plate 501, the connection strength and stability between the support member and the bow section 200 of the vessel can be improved.
[0043] Figure 6 As shown, the tooling for launching ship airbags also includes multiple reinforcing elbow plates 600, which are disposed within the bottom plate of the bow section 200 of the ship. Each reinforcing elbow plate 600 is respectively disposed with respect to the end of its corresponding support member closest to the ship. In this embodiment, by providing reinforcing elbow plates 600, the vertical load borne by the support member can be effectively transferred to the reinforcing elbow plate 600 and the inner wall of the hull, avoiding local stress concentration and improving the deformation resistance and structural safety of the entire bow section of the ship.
[0044] In summary, the tooling for launching airbags for ships of this utility model uses a support structure 500 to connect the bottom plate 400 and the bow 200 of the ship respectively. During the launching process of the ship on the slipway, the two sets of tooling are respectively connected to the lower sides of both sides of the bow 200 of the ship, and the bottom of the ship and the two sets of tooling are respectively placed on the airbags 300. When the bottom plate of the bow 200 reaches the end of the slipway 100 at the change of the bottom plate shape, the airbags 300 under the tooling will not immediately detach under the support of the tooling, so that the airbags 300 still bear the weight of the bow 200 of the ship and move into the water with the ship. Since the bottom plate 400 of the tooling extends beyond the bow 200 of the ship along the length of the ship, when the foremost end of the bottom plate reaches the end of the slipway 100, the airbag 300 under the tooling can still support the bow 200 of the ship, thereby preventing the bow 200 of the ship from colliding with the slipway 100 and improving the safety of the ship when the airbag is launched.
