Description

Technical Field

[0001] This utility model relates to an anchor chain installation auxiliary platform, and belongs to the field of anchor chain installation technology. Background Technology

[0002] The floating offshore wind power mooring system adopts an anchor + anchor chain combination structure. After the floating offshore wind power foundation is transported to the construction site, the anchor chains stored on the seabed need to be retrieved to the sea surface and reconnected to the anchor chains of the floating foundation.

[0003] The existing technology (see Chinese Patent Publication No. CN116750137A) involves temporarily fixing the anchor chain stored on the seabed to the salvage vessel after it is salvaged. The salvage vessel can only leave after the anchor chain stored on the seabed is reconnected to the anchor chain of the floating foundation, which reduces the construction efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides an anchor chain installation auxiliary platform.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides an anchor chain installation auxiliary platform, comprising: The backing base, diagonal braces, and backing top frame constitute an installation auxiliary platform frame.

[0007] The reconnection base frame has an arc-shaped inner surface facing the floating foundation; the reconnection base frame has an installation port.

[0008] The reconnection base frame located at the installation port is fixed with a base plate, and the base plate is fixed with spaced vertical plates; the vertical plates are provided with arc-shaped slots that can rotatably hold a collar roller that is sleeved with the end of the nylon cable of the submarine wet anchor chain.

[0009] A retractable limiting rod is fixed to the base plate. One end of the limiting rod is fixed to the base plate, and the other end of the limiting rod extends into the spaced vertical plates.

[0010] The reconnection base frame has four inclined rods fixed on both sides, which are inclined upwards relative to the inner side. The inclined rods are connected to the suspension ropes. It also includes a floating base, and the suspension ropes are connected to the floating base. The four suspension ropes are positioned above and below the two inclined rods on the inner side of the floating base to connect to the floating base in four places.

[0011] The top of the four inclined rods is fixed with a reconnection top frame, and the reconnection top frame is equipped with a hand-operated hoist for hoisting the anchor chain of the floating foundation; the floating foundation has an anchor chain that reconnects to the end of the nylon cable of the anchor chain stored on the seabed, and the end of the anchor chain has a shackle for reconnection by sleeve with a pin shaft.

[0012] The collar roller has a through hole in the middle for connecting the lifting cable.

[0013] The beneficial effects of this utility model are as follows: the reconnection base frame, diagonal rod, and reconnection top frame are combined into an installation auxiliary platform frame, which is connected to the four lifting lugs of the floating foundation through four lifting ropes. When reconnecting the anchor chains on the floating foundation to each other, the side of the floating foundation is used as the reconnection construction environment. After the salvage vessel retrieves the wet anchor chain nylon cable end from the seabed and places it on the reconnection base frame with the collar roller, the salvage vessel can then leave, improving construction efficiency.

Detailed Implementation

[0015] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0016] like Figures 1 to 2 As stated above.

[0017] This application discloses an anchor chain installation auxiliary platform, comprising: The inner side of the floating foundation 6 is an arc-shaped reconnection base 3. The reconnection base 3 has an installation port 31, through which the end 45 of the seabed wet anchor chain nylon cable is passed.

[0018] The reconnection base frame 3 located at the installation port 31 is fixed with a base plate 32, and the base plate 32 is fixed with spaced upright plates 33; the upright plate 33 is provided with an arc-shaped slot to rotatably mount a collar roller 34, and a pin 44 can pass through the through hole of the collar roller 34, and the collar roller 34 is sleeved with the end 45 of the nylon cable of the seabed wet anchor chain.

[0019] A limiting rod 35 is fixed on the base plate 32. One end of the limiting rod 35 is fixed on the base plate 32, and the other end of the telescopic limiting rod 35 extends into the spaced vertical plates 33. The telescopic end of the limiting rod 35 locks the collar roller 34 for rotational limitation.

[0020] The reconnecting base frame 3 has four inclined rods 2 fixed on both sides. The four inclined rods 2 are inclined upwards relative to each other on the inner side. The lifting lugs fixed to the inclined rods 2 are connected to the lifting ropes 21. The lifting ropes 21 are connected to the lifting lugs fixed on the floating base 6. The four lifting ropes 21 are positioned vertically relative to the two inclined rods 2 on the inner side of the floating base 6 to connect with the four lifting lugs of the floating base 6.

[0021] The top of the four inclined rods 2 is fixed with a reconnection top frame 4. The reconnection top frame 4 is equipped with a hand chain hoist 62 for hoisting the anchor chain 61 of the floating foundation 6. When the anchor chain 61 on the floating foundation 6 is reconnected to the end 45 of the wet anchor chain nylon cable on the seabed, the hand chain hoist 62 lifts the weight of the anchor chain 61, the collar roller 34 passes through the pin 44, and the shackle 63 at the end of the anchor chain 61 is sleeved and installed with the pin 44 to realize the reconnection of the end 45 of the wet anchor chain nylon cable on the seabed to the anchor chain 61 on the floating foundation 6.

[0022] The collar roller 34 has a through hole in the middle for connecting to the lifting cable 5. The lifting cable 5 lifts the collar roller 34, which is fitted with the end 45 of the submarine wet anchor chain nylon cable, so that the collar roller 34 is locked in the arc-shaped slot of the upright plate 33. Then the lifting cable 5 is released to make room for the subsequent pin shaft 44 to pass through.

[0023] The reconnection base frame 3, diagonal brace 2, and reconnection top frame 4 form an installation auxiliary platform frame. It is connected to the four lifting lugs of the floating foundation 6 by four lifting ropes 21. When reconnecting the anchor chain 61 on the floating foundation 6, the side of the floating foundation 6 is used as the reconnection construction environment. After the salvage vessel retrieves the wet anchor chain nylon cable end 45 on the seabed and places it on the reconnection base frame 3 with the collar roller 34, the salvage vessel can then leave, improving construction efficiency.
