Figure 2 Schematic diagram of the support airbag and the support member in some embodiments of the present application.

[0033] The present application provides a bow support structure of a ship using an airbag for launching, the support structure comprising a support airbag 1, a support member 2 and a rolling airbag 3. The support airbag 1 is used to be arranged below the bow of the ship and is connected to the ship through a first rope 4. The support member 2 is arranged on a side of the support airbag 1 away from the ship, the support member 2 and the support airbag 1 are in contact with each other, and the support member 2 is connected to the ship through a second rope 5. The rolling airbag 3 is arranged on a side of the support member 2 away from the support airbag 1, and the rolling airbag and the support member 2 are rollingly matched.

[0034] In some embodiments, the supporting airbag 1 and the rolling airbag 3 can both be inflatable rubber airbags for ships, which include a bag body, a bag head, and end iron pieces. The end iron pieces are arranged on the top of the bag head and are used to inflate and deflate the airbags. The bag body is the cylindrical part of the airbag, which is the working part of the airbag and is used to achieve support and rolling of the ship.

[0035] In some embodiments, in the support airbag 1, the outer contour of the bag body can be similar to a block, so as to provide stable support like a ship.

[0036] The first rope 4 can be a steel rope, one end of which can be fixed to the support airbag 1 by a clamp, and the other end of the first rope 4 can be set on the ship. For example, an anchor rod is provided on the ship, and the other end of the first rope 4 is sleeved on the anchor rod. The first rope 4 can be removed from the anchor rod by a mechanical arm or other machinery.

[0037] The support member 2 may be a plate-like structure to increase the contact area of ​​the ship when launching into the water. In some embodiments, the material of the support member 2 may include aluminum, steel or other metal materials.

[0038] The second rope 5 can be a steel rope, one end of the second rope 5 can be welded to the support 2, and the other end of the second rope 5 can be set on the ship. For example, an anchor rod is set on the ship, and the other end of the second rope 5 is sleeved on the anchor rod. The second rope 5 can be removed from the anchor rod by a mechanical arm or other machinery.

[0039] Optionally, the other end of the first rope 4 and the other end of the second rope 5 can be combined into one to form a combined rope. The combined rope can be sleeved on the anchor rod, and the combined rope can be removed from the anchor rod by a robotic arm or other machinery to allow the support airbag 1 and the support member 2 to fall off at the same time.

[0040] In the above scheme, by providing a support airbag 1 and a support member 2 to replace the steel support structure welded to the ship in the related art, after the ship is launched, the support airbag 1 and the support member 2 can be separated from the hull by removing the first rope 4 and the second rope 5, without the need for underwater cutting, and can be reused after salvage, eliminating the construction step of docking and dismantling the bow support structure, and eliminating the need to repaint the bow outer plate. It is easy to use and saves costs.

[0041] According to some embodiments of the present application, the number of the supporting airbags 1 is at least two. Along the width direction of the ship, at least two supporting airbags 1 are arranged at intervals, and two adjacent airbags are connected by a third rope 6.

[0042] In the above solution, a plurality of supporting airbags 1 are provided to jointly support the ship.

[0043] According to some embodiments of the present application, the number of the support airbags 1 is two, including a port support airbag 11 and a starboard support airbag 12. The port support airbag 11 is located below the port side of the ship, and the starboard support airbag 12 is located below the starboard side of the ship. The area defined by the port support airbag 11 and the starboard support airbag 12 is larger than the area of ​​the straight area of ​​the bow of the ship.

[0044] According to some embodiments of the present application, the port support airbag 11 and the starboard support airbag 12 are connected by a third rope 6 , and one end of the third rope 6 is fixed to the port support airbag 11 , and the other end is fixed to the starboard support airbag 12 .

[0045] In the above scheme, the port support airbag 11 and the starboard support airbag 12 are connected by the third rope 6 to reduce the risk of the port support airbag 11 and the starboard support airbag 12 being squeezed out of each other and unable to support the ship due to the influence of the ship's gravity during the launching process of the ship.

[0046] According to some embodiments of the present application, one end of the first rope 4 away from the support airbag 1 is detachably connected to the ship, and one end of the second rope 5 away from the support airbag 1 is detachably connected to the ship.

[0047] According to some embodiments of the present application, one end of the first rope 4 away from the supporting airbag 1 is combined with one end of the second rope 5 away from the supporting airbag 1 as a whole, and are jointly and detachably connected to the ship.

[0048] According to some embodiments of the present application, the air filling port of the support airbag 1 is arranged toward the outside of the ship.

[0049] In some embodiments, the air filling port of the support airbag 1 is arranged outward to facilitate air filling.

[0050] Exemplarily, the air filling port of the port support airbag 11 is arranged away from the starboard support airbag 12 , and the air filling port of the starboard support airbag 12 is arranged away from the port support airbag 11 .

[0051] According to some embodiments of the present application, the support member 2 is a steel plate.

[0052] According to some embodiments of the present application, there are multiple rolling airbags 3, and the multiple rolling airbags 3 are arranged at intervals along the length direction of the ship.

[0053] Some embodiments of the present application provide a method for launching a ship, using the bow support structure of the ship for launching by airbag provided in the first aspect.

[0054] See also Figure 3 , Figure 3 This is a flowchart of a method for launching a ship in some embodiments of the present application.

[0055] The method comprises the following steps:

[0056] S1. Install the support airbag, the support member and the rolling airbag in sequence below the bow of the ship, and inflate the support airbag and the rolling airbag;

[0057] S2. Push the ship into the water;

[0058] S3. Remove the first rope and the second rope, and salvage and recover the supporting airbag and the supporting member.

[0059] Among them, the working process of the support structure provided by this application is described:

[0060] When the ship is launched, the supporting airbags (port and starboard supporting airbags) and the steel plate are pulled by the first and second ropes and move synchronously with the ship. When the ship slides down to the stern, the bow of the ship applies force to the port and starboard supporting airbags. The port and starboard supporting airbags are pulled by the third rope and will not be squeezed out when under pressure. The port and starboard supporting airbags apply force to the steel plate, and the steel plate applies force to the rolling airbag. The bow of the ship is acted upon by the reaction force of the port and starboard supporting airbags, and the action width is greater than the straight area of ​​the bow of the ship, which increases the lateral stability of the ship. After the ship is launched, after the first and second ropes are removed, the port and starboard supporting airbags and the steel plate can be separated from the hull and can be reused after salvage, thereby eliminating the construction link of dismantling the bow support structure during docking and the need to repaint the bow outer plate. It is easy to use and saves costs.

[0061] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
