Description

Technical Field

[0001] The invention relates to the field of ship hull construction, in particular to a welding device for constructing bilge sections of a bulk carrier. Background Art

[0002] The bilge refers to the curved part of the hull connecting the bottom and the side of the ship, also called the bilge. The strakes at the bilge are called bilge strakes, or bilge for short. They are set to prevent splashing water from scouring the side or wetting the deck when the planing boat is sailing, so most planing boats are equipped with bilge strakes. There are three types of bilge strakes: horizontal, vertical and figure eight bilge strakes. The bilge keel is a continuous profile installed at the bilge of the ship, which is the linear part connecting the side and the bottom plate. It is generally installed on ships with a small square coefficient to enhance wave resistance and stability. Under reasonable design conditions, it can greatly reduce roll and pitch, but it will also reduce the maneuverability of the ship accordingly. The length of the bilge keel is generally 1 / 3 to 1 / 2 of the ship length, and its structural forms include single plate and double plate.

[0003] However, most of the bilges on the market currently adopt the upside-down welding method, which requires the installation of welding platforms on multiple sides of the bilge. After the bilge connection is completed, it is rather cumbersome to dismantle the platform. Summary of the invention

[0004] In view of the existing problems, the present invention provides a welding device for constructing bilge sections of a bulk carrier, which can effectively solve the problems raised in the background technology when used in combination.

[0005] To solve the above problems, the present invention adopts the following technical solutions:

[0006] A welding device for constructing a bilge section of a bulk carrier comprises a cargo ship bilge, wherein the cargo ship bilge comprises a plurality of bilge support frames arranged in an array, a limiting bayonet is provided on one side of the bilge support frame, a bottom welding plate is provided on the side of the bilge support frame close to the limiting bayonet, a limiting hook is provided on the upper surface of the bottom welding plate, a first welding plate is provided on the other side of the bilge support frame, a platform bracket is provided on the outer surface of the first welding plate, a hook removal platform is provided on the outer side of the platform bracket, a connecting bracket is connected between the hook removal platform and the platform bracket, a limiting ratchet is provided inside the platform bracket, a rotating shaft is installed between the limiting ratchet and the connecting bracket, a ratchet is provided on the outer side of the limiting ratchet on the lower surface of the hook removal platform, an elastic rotating shaft is installed between the ratchet and the hook removal platform, and a D-shaped lifting ring is installed on the upper surface of the first welding plate on the outer side of the hook removal platform.

[0007] As a further solution of the present invention: a mounting screw is installed on the platform bracket through the outer surface of the first welding plate, and a limiting nut is sleeved on the outer side of the mounting screw located on the other side of the platform bracket.

[0008] As a further solution of the present invention: a hull welding plate is provided at one end of the bottom welding plate on the outside of the bilge support frame, and a second welding plate is provided between the hull welding plate and the first welding plate on the outside of the bilge support frame.

[0009] As a further solution of the present invention: the outer side of the bilge support frame is provided with a limit rib installation groove, and the inner sides of the first welding plate, the second welding plate and the hull welding plate are all provided with welding plate limit ribs inside the limit rib installation groove.

[0010] As a further solution of the present invention: a reinforcing channel steel is installed on the side of the bilge support frame close to the limit clamp, a channel steel clamping groove is opened on the upper surface of the bottom welding plate just below the reinforcing channel steel, and a weight reduction hole is arranged inside the bilge support frame, and the reinforcing channel steel is clamped in the channel steel clamping groove.

[0011] As a further solution of the present invention: the pawl is rotatably connected to the hook removal platform via the elastic rotating shaft, and the pawl is engaged with the limiting ratchet.

[0012] As a further solution of the present invention: the position-limiting ratchet and the connecting bracket are both rotatably connected to the platform bracket via the rotating shaft.

[0013] As a further solution of the present invention: the first welding plate, the second welding plate and the hull welding plate are all fixed to the bilge support frame by welding.

[0014] As a further solution of the present invention: the first welding plate, the second welding plate and the hull welding plate are all clamped with the limiting rib mounting grooves through the welding plate limiting ribs.

[0015] As a further solution of the present invention: both ends of the D-shaped lifting ring are provided with lifting ring blocks, the end of the lifting ring block is located inside the D-shaped lifting ring and a clamp push rod is installed, the outer side of the clamp push rod is installed with a bayonet, and the outer side of the bayonet is located on the side surface of the D-shaped lifting ring and a bayonet groove is installed.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The bilge includes a bottom welding plate, a first welding plate, a second welding plate and a hull welding plate, which are assembled and fixed by segmented welding. Compared with the traditional integrated bilge, the assembly accuracy of the bilge support frame can be more accurately guaranteed, avoiding the interference situation that causes the bilge support frame to be unable to be assembled inside the cargo ship's bilge.

[0018] 2. After the D-shaped lifting ring is integrally connected to the inside of the lifting ring installation groove, the clamping pin is clamped to the inside of the clamping pin groove, so that the clamping block push rod is clamped to the inside of the lifting ring installation groove, so that the D-shaped lifting ring can lift the cargo ship bilge as a whole, and the D-shaped lifting ring can be disassembled in conjunction with the hook removal platform.

[0019] 3. The hook removal platform can be rotated unidirectionally toward the connection end of the first welding plate and the bottom welding plate. The pawl on the lower surface of the hook removal platform ensures the limiting effect between multiple tooth gaps of the limiting ratchet under the action of the elastic rotating shaft, so that the hook removal platform after adjusting the position can be used for the user to stand to remove the hook installed on the D-shaped lifting ring. The hook removal platform as a whole passes through the first welding plate through the installation screw and then is limited by the limiting nut, which can be easily installed and disassembled.
