Description

Technical Field

[0001] The present invention relates to the field of offshore wind power, and in particular to an offshore wind power foundation hoisting integrated engineering vessel. Background Art

[0002] As the country's demand for clean energy becomes more urgent, the concepts of carbon neutrality and carbon peak are proposed, and the offshore wind power field has developed very rapidly in recent years, the installed capacity of a single wind turbine has continued to increase, so the size and weight of the foundation structure are constantly increasing. Therefore, the requirements for offshore construction ships and machinery are also constantly increasing. The traditional offshore wind power foundation installation mode is to first make the wind power foundation at the dock base, use a shore crane at the dock to lift the wind power foundation to the transport barge, and then use the transport barge to transport the wind power foundation to the target sea area, wait for better sea conditions, and use a floating crane to lift the foundation from the barge and install it at the target location. Due to the increasing sea conditions, With the continuous development of wind power, the tonnage size of wind turbine foundations has been continuously increasing. There are many constraints in the traditional installation process. First of all, it requires a dock with large tonnage lifting capacity, as well as large-tonnage flatbed barges and floating cranes with large tonnage lifting capacity. These ship and machinery resources are currently in short supply domestically and even internationally, and the cost of using them is also very high. Since the construction process is all at sea, it is subject to the influence of the offshore construction environment and it is difficult to find a suitable window period. In addition, since two ships are cooperating in the construction, they are affected by wind and waves and there is relative movement between the two ships. There are great risks and uncontrollable processes such as lifting hooks, releasing sea lashings, and installation inspection.

[0003] Therefore, the invention of the integrated engineering vessel for lifting and transporting offshore wind power foundations is very necessary. Summary of the Invention

[0004] The purpose of the present invention is to provide an integrated engineering vessel for lifting offshore wind power foundations, which realizes the lifting of offshore wind power foundations through a mobile lifting mechanism, thereby solving many problems of traditional offshore wind power foundation lifting and installation, simplifying the shipping steps, greatly saving construction costs, and reducing construction risks.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an offshore wind power foundation hoisting integrated engineering vessel, comprising a hull, a flatbed barge disposed above the hull, and upright trolley track trusses disposed on the left and right sides of the flatbed barge, at least two mobile hoisting mechanisms disposed above the trolley track trusses, the left and right sides of the mobile hoisting mechanisms being slidably connected to the trolley track trusses on the left and right sides, respectively;

[0006] A trolley cantilever track truss is provided on one side of the trolley track truss close to the bow, and the trolley cantilever track truss is connected to the upper side of the trolley track truss extending toward the outside of the bow;

[0007] The flat barge is provided with a plurality of fixing blocks.

[0008] Furthermore, the upper surfaces of the trolley track truss and the trolley cantilever track truss are paved with trolley tracks, and trolley stop blocks are provided on both sides of the trolley tracks.

[0009] Furthermore, the mobile hoisting mechanism includes a trolley traveling mechanism and a flippable trolley truss beam, and the trolley traveling mechanism is arranged on the trolley track.

[0010] Furthermore, one side of the flippable trolley truss beam is flip-connected to the trolley traveling mechanism through a trolley truss beam flipping mechanism, and the other side of the flippable trolley truss beam is placed on a support rod, and the support rod is fixedly connected to the trolley traveling mechanism on one side.

[0011] Furthermore, at least two trolley running mechanisms and trolley tracks are provided on the upper side of the reversible trolley truss beam, and the trolley running mechanism is slidably connected to the reversible trolley truss beam through the trolley track. The trolley truss beam is provided with a turntable frame on one side close to the trolley truss beam turning mechanism, and a trolley stop block is provided on the other side. A first turntable is provided on the top of the turntable frame, and a second turntable is provided on the top of the trolley stop block.

[0012] Furthermore, the trolley truss beam flipping mechanism includes a flipping drive machine and a flipping A-shaped frame. A third wheel is provided on the top of the flipping A-shaped frame. A fourth wheel is provided on the outermost side of the trolley truss beam flipping mechanism. The second wheel, the third wheel and the fourth wheel are connected in sequence by steel ropes.

[0013] Furthermore, a slot is provided on the upper surface of the flip trolley truss beam, and a latch is provided on the inner side of the flip A-shaped frame.

[0014] Furthermore, the height of the latch member is the height of the slot after the truss beam of the reversible trolley is flipped.

[0015] Furthermore, the length of the trolley cantilever track truss extending outward from the bow is greater than the width of the offshore wind power foundation.

[0016] Furthermore, a hook is provided below the trolley traveling mechanism, and the hook is driven and connected to the trolley traveling mechanism, the third rotating wheel and the trolley truss beam turning mechanism in sequence.

[0017] In summary, the beneficial effects of the invention are:

[0018] 1. The present invention adopts an integrated lifting engineering vessel and is equipped with a trolley cantilever track truss. The choice of production base is not restricted by shore cranes. As long as there is an open space at a seaside dock, the production of wind power foundations can be carried out.

[0019] 2. The present invention adopts an integrated lifting engineering vessel, because only one vessel is needed for construction on site, which reduces the coordination risk between ships on site. Moreover, there is no relative motion relationship between the two ships, and the requirements for sea conditions and weather are greatly reduced, and the construction efficiency is greatly improved.

[0020] 3. The lifting system of the present invention adopts a rail-type design. During lifting, it is only necessary to operate the movement of the trolley and the small car and coordinate the loading of the hook to realize the offshore transportation link. The fully mechanized construction greatly simplifies the operation steps and difficulty, improves the construction efficiency and improves the economy. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to illustrate the invention and are not intended to limit the invention.

[0027] like Figure 1-4 As shown, the present invention is an offshore wind power foundation lifting integrated engineering vessel, comprising a hull 1, a flatbed barge 2 is provided above the hull 1, and upright trolley track trusses 3 are provided on the left and right sides of the flatbed barge 2, at least two mobile lifting mechanisms 5 are provided above the trolley track trusses 3, and the left and right sides of the mobile lifting mechanisms 5 are respectively slidably connected to the trolley track trusses 3 on the left and right sides;

[0028] Preferably, a trolley cantilever track truss 4 is provided on the side of the trolley track truss 3 close to the bow, and the trolley cantilever track truss 4 is connected to the upper side of the trolley track truss 3 and extends toward the outside of the bow. The function of the trolley cantilever track truss 4 is to insert the trolley cantilever track truss 4 into both sides of the offshore wind power foundation 7 when the hull 1 is docked on the shore, and then drive the trolley traveling mechanism 504 to the top of the offshore wind power foundation 7, so as to facilitate the lifting of the offshore wind power foundation 7 on the shore.

[0029] In some embodiments, a plurality of fixing blocks 6 are provided on the flat barge 2, and the fixing blocks 6 are used to fix the offshore wind power foundation 7 that has been transported onto the flat barge 2 to prevent it from moving or overturning during the voyage.

[0030] Furthermore, a trolley track 31 is laid on the upper surface of the trolley track truss 3 and the trolley cantilever track truss 4, which facilitates the mobile lifting mechanism 5 to move back and forth on the trolley track truss 3 and the trolley cantilever track truss 4. Trolley stop blocks 32 are provided on the left and right sides of the trolley track 31. The trolley stop blocks 32 can prevent the mobile lifting mechanism 5 from leaving the track. The mobile lifting mechanism 5 includes a trolley traveling mechanism 501 and a flippable trolley truss beam 502. The trolley traveling mechanism 501 is arranged on the trolley track 31.

[0031] Furthermore, one side of the flippable trolley truss beam 502 is flip-connected to the trolley traveling mechanism 501 through the trolley truss beam flipping mechanism 503, and the other side of the flippable trolley truss beam 502 is placed on the support rod 507. The height of the support rod 507 is to match the height of the trolley truss beam flipping mechanism 503 so that the flippable trolley truss beam 502 is placed horizontally. It should be noted that, as needed, a support rod 507 can also be added to the side of the trolley truss beam flipping mechanism 503 to adapt to offshore wind power foundations 7 of different heights. The support rod is fixedly connected to the trolley traveling mechanism 501 on one side.

[0032] At least two trolley running mechanisms 504 and trolley tracks 505 are provided on the upper side of the reversible trolley truss beam 502. The trolley running mechanism 504 is slidingly connected to the reversible trolley truss beam 502 through the trolley track 505. The trolley truss beam 502 is provided with a turntable frame 510 on one side close to the trolley truss beam reversing mechanism 503, and a trolley stop block 511 on the other side. A first turntable 512 is provided on the top of the turntable frame 510, and a second turntable 513 is provided on the top of the trolley stop block 511.

[0033] The trolley truss beam flipping mechanism 503 includes a flipping drive motor 508 and a flipping herringbone 509. A third rotary wheel 514 is provided on the top of the flipping herringbone 509. A fourth rotary wheel 515 is provided on the outermost side of the trolley truss beam flipping mechanism 503. The second rotary wheel 513, the third rotary wheel 514 and the fourth rotary wheel 515 are connected in sequence by steel ropes 516. When the trolley truss beam 502 needs to be flipped, the flipping drive motor 508 is started, and the steel rope 516 drives the trolley truss beam 502 to flip and stand up through the above-mentioned pulleys.

[0034] In some embodiments, a slot 517 is provided on the upper surface of the reversible trolley truss beam 502, and a latch 518 is provided on the inner side of the reversible A-frame 509. The height of the latch 518 is the height of the slot 517 after the reversible trolley truss beam 502 is flipped. This design is to ensure that when the reversible trolley truss beam 502 is flipped, the latch 518 and the slot 517 can be fixed to each other, which can effectively prevent the reversible trolley truss beam 502 from falling accidentally.

[0035] Furthermore, the length of the trolley cantilever track truss 4 extending outward from the bow is greater than the width of the offshore wind power foundation 7 to ensure that the trolley cantilever track truss 4 can be fully inserted into both sides of the offshore wind power foundation 7 .

[0036] Furthermore, a hook 506 is provided below the trolley traveling mechanism 504, and the hook 506 is driven and connected to the trolley truss beam turning mechanism 503 through the trolley traveling mechanism 504 and the third rotating wheel 514 in sequence. The motor in the trolley truss beam turning mechanism 503 can also drive the operation of the hook 506.

[0037] The working principle of the present invention is as follows:

[0038] Please refer to Figure 1-4 The construction party can transport the offshore wind power foundation 7 to the front of the dock at any dock, then dock the hull 1 in a T-shape with the dock, and slowly insert the trolley cantilever track truss 4 into both sides of the offshore wind power foundation 7.

[0039] After the hull 1 is docked, the two mobile hoisting mechanisms 5 begin to move, and the tilting drive 508 is activated. The steel rope 516 passes through the second, third, and fourth runners 513, 514, and 515, and the tilting herringbone 509 is used to pull up the tiltable trolley truss beam 502. Then, the two mobile hoisting mechanisms 5 are moved from the trolley track truss 3 to the trolley cantilever track truss 4 using the trolley travel mechanism 501. After the two mobile hoisting mechanisms 5 are positioned on both sides of the offshore wind turbine foundation 7, the tilting drive 508 is activated to lower the tiltable trolley truss beam 502. The trolley travel mechanism 504 is then activated, moved to the appropriate position, and the offshore wind turbine foundation 7 is lifted using the hook 506.

[0040] Then, the trolley travel mechanism 501 is started again, and the offshore wind power foundation 7 is moved to a suitable position on the flat barge 2 through the trolley track truss 3, and the hook 506 is lowered until the fixing block 6 completely fixes the offshore wind power foundation 7.

[0041] By repeating the above steps, multiple offshore wind power foundations 7 can be lifted if the load capacity of the hull 1 allows.

[0042] After the lifting is completed, the engineering ship transports the offshore wind power foundation 7 to the target sea area. The reverse operation of the above steps can be used to lift the offshore wind power foundation 7 to the target sea area, completing the entire process of lifting onto the ship, sea transportation, lifting, sinking and installation.
