Description

Technical Field

[0001] This utility model relates to the field of pontoon technology, and in particular to a pontoon connection device suitable for assembly on water. Background Technology

[0002] Floating boxes are widely used in various surface water facilities. Depending on their function, floating boxes are connected together to form a whole, providing the required buoyancy. The connection between floating boxes generally adopts a welded connection structure or a structure with sealing strips and fastening bolts. Welded structures are strong, but are not convenient for disassembly and assembly.

[0003] Small dredgers are mainly used for dredging operations in inland rivers and lakes. To adapt to frequent relocation operations, the hull is designed to be capable of being moved between water and land. Land relocation is limited by road transport (height less than 4 meters, width less than 3 meters). The small dredger is 56.5 meters long and 7.9 meters wide, and its pontoons need to adopt a detachable structure. Conventional sealing strips and fastening bolts are used for connection devices, which are easy to disassemble and assemble. However, in order to maximize buoyancy, the pontoons are generally made as lightweight as possible. The structure of the connection parts is prone to deformation under stress, and repeated disassembly and assembly can easily lead to water leakage at the sealing surface. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a floating box connection device suitable for waterborne assembly.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a floating box connection device suitable for water assembly, used to connect the main floating box and the side floating box, providing buoyancy and maintaining a tight connection between the floating boxes. Its innovation lies in: including a bottom hook, round steel, mating flanges and fastening bolts.

[0006] The mating flange includes a first flange and a second flange, which are respectively fixedly installed on the top of the adjacent sides of the main buoy and the side buoy. The first flange and the second flange are tightly connected by fastening bolts to ensure reliable assembly of the upper part of the buoy and ensure reliable connection under stress.

[0007] The bottom hook is fixedly installed on the bottom side of the side buoy located near the main buoy. The bottom hook includes a block, and a groove is formed on the top of the block.

[0008] The bottom of the main buoy box near the side buoy box is fitted with round steel bars that fit perfectly within the groove. These round steel bars are used to transmit buoyancy and lateral force, maintaining a tight connection between the buoy boxes.

[0009] Furthermore, the groove includes an upper conical groove and a lower arc-shaped groove that are connected vertically, and the inner diameter of the upper conical groove decreases from top to bottom.

[0010] Furthermore, the system also includes a reinforcing rib structure, which is installed between the bottom hook and the side float to ensure reliable connection under stress.

[0011] Furthermore, a fixed base is installed on the bottom side of the main buoy near the side buoy, and a rectangular receiving area is left on the side of the fixed base near the side buoy. The rectangular receiving area can accommodate the hook head of the bottom hook extending into it, and the round steel is fixed on the top wall inside the rectangular receiving area.

[0012] Furthermore, the round steel bar includes an upper vertical connecting part and a bottom circular connecting part.

[0013] The advantages of this utility model are:

[0014] 1. The bottom hook in this structure is used in conjunction with round steel, and the upper part of the pontoon is connected by fastening bolts, which solves the problem of water leakage on the sealing surface caused by frequent disassembly and assembly of the hull structure.

[0015] 2. This structure is mainly used in prefabricated hull structures. Utilizing the buoyancy difference between the main buoy and the side buoys, hooks are used to connect the buoys below the waterline, while bolts are used above the waterline. Four side buoys are connected to the main buoy, providing sufficient buoyancy for the entire hull to float. The hooks are installed at the bottom of the side buoys with the grooves facing upwards, and they mate with the round steel bars at the bottom of the main buoy. The buoyancy of the side buoys is transferred to the main buoy through the hooks. The lateral forces between the buoys are eliminated in two parts: the hook heads and the round steel bars eliminate the bottom lateral forces.

[0016] 3. The floating pontoon connection device used in this waterborne assembly does not use soft sealing, which can ensure that the hull structure remains well sealed after multiple disassemblies and reassemblies. During disassembly and reassembly, personnel operate above the water surface, making construction safe and convenient. Attached Figure Description

[0019] like Figure 1The above describes a floating box connection device suitable for waterborne assembly, used to connect the main floating box 4 and the side floating box 5, providing buoyancy and maintaining a tight connection between the floating boxes. It includes a bottom hook 1, a round steel bar 2, a mating flange, fastening bolts, and a reinforcing rib structure 3. The bottom hook 1 cooperates with the round steel bar 2, and the upper part of the floating box adopts a fastening bolt connection structure, which solves the problem of water leakage at the sealing surface caused by frequent disassembly and assembly of the hull structure.

[0020] The mating flanges include a first flange and a second flange, which are fixedly installed on the top of the adjacent sides of the main buoy 4 and the side buoy 5, respectively. The first flange and the second flange are tightly connected by fastening bolts to ensure reliable assembly of the upper part of the buoy and to ensure reliable connection under stress.

[0021] In this embodiment, both the first flange and the second flange are square flanges.

[0022] The bottom hook 1 is fixedly installed on the bottom side of the side buoy 5, which is close to the main buoy 4. The bottom hook 1 includes a block, and a groove is provided on the top of the block.

[0023] The groove includes an upper conical groove and a lower arc-shaped groove that are connected vertically, and the inner diameter of the upper conical groove decreases from top to bottom.

[0024] The bottom of the main buoy 4 near the side buoy 5 is fitted with a round steel bar 2 that matches the groove. The round steel bar 2 is used to transmit buoyancy and lateral force and keep the buoys tightly connected.

[0025] The reinforcing rib structure 3 is set between the bottom hook 1 and the side float 5 to ensure the reliability of the connection under stress.

[0026] A fixed seat 6 is installed at the bottom of the main buoy 4 near the side buoy 5. The fixed seat 6 is made of a reinforcing rib plate and a vertical plate. A rectangular receiving area 7 is left near the side buoy 5 of the fixed seat 6. The rectangular receiving area 7 can accommodate the hook head of the bottom hook 1 extending into it. A round steel bar 2 is welded and fixed on the top wall inside the rectangular receiving area 7.

[0027] The round steel bar 2 includes an upper vertical connecting section and a bottom circular connecting section.

[0028] This structure is primarily used in prefabricated hull structures. Utilizing the buoyancy difference between the main buoy 4 and the side buoy 5, hooks are used to connect the buoys below the waterline, while bolts are used above the waterline. Four side buoys 5 are connected to the main buoy 4, providing sufficient buoyancy for the entire hull to float. The hooks are installed at the bottom of the side buoy 5 with the grooves facing upwards, and they mate with the round steel 2 at the bottom of the main buoy 4. The buoyancy of the side buoy 5 is transferred to the main buoy 4 through the hooks. The lateral forces between the buoys are eliminated in two parts: the hook head and the round steel 2 eliminate the bottom lateral forces.

[0029] The floating pontoon connection device used in this waterborne assembly does not employ soft sealing, ensuring that the hull structure remains well-sealed after multiple disassemblies and reassemblies. During disassembly and reassembly, personnel operate above the water surface, making construction safe and convenient.

[0030] The working principle of this patent:

[0031] This structure is a structural device used on prefabricated ship hulls, whose main function is to connect pontoons and ensure that there is no water leakage between the pontoons.
