Description

Technical Field

[0001] This application relates to the field of marine engineering technology, and more specifically, to a pile driving positioning auxiliary support and positioning method. Background Technology

[0002] With the rapid development of offshore wind power, offshore photovoltaic and other marine engineering projects, increasingly higher requirements are being placed on the construction precision of underwater foundation structures. For example, in the construction of photovoltaic power stations in shallow sea areas, multiple steel pipe piles are often used as the supporting foundation for the upper platform, which requires that the driving position and verticality of each steel pipe pile be precisely controlled.

[0003] Traditional offshore steel pipe pile driving construction typically employs a large floating crane vessel in conjunction with a positioning frame. However, this method utilizes a bottom-sitting positioning frame, which is quite heavy, leading to high costs. Furthermore, the positioning frame requires a large lifting radius, placing significant demands on the floating crane itself. Additionally, offshore photovoltaic projects are usually conducted in shallow waters, and the large draft of the floating crane vessel poses a risk of bottoming out. In contrast, bottom-sitting vessels have a shallow draft, offering a natural advantage in shallow water operations and effectively reducing costs and risks. However, once bottom-sitting vessels are seated, their hull attitude can be affected by the unevenness of the seabed, causing them to tilt, and their positioning may also deviate slightly.

This effectively compensates for significant pitch attitude deviations caused by uneven seabed conditions and achieves high-precision leveling of the positioning frame. Simultaneously, by combining a first position adjustment component for positioning along the first direction of the hull-mounted vessel, a second position adjustment component for positioning along the second direction of the hull-mounted vessel, and an angle adjustment mechanism for azimuth positioning, comprehensive compensation for the translational and rotational degrees of freedom of the pile body in three-dimensional space is achieved. This effectively overcomes the positional deviation of the hull-mounted vessel, ensuring high precision in pile driving operations and demonstrating strong adaptability. Furthermore, the pile driving positioning auxiliary support enables the hull-mounted vessel, with its lower operating costs, to undertake high-precision pile driving tasks, avoiding reliance on expensive large floating cranes, significantly reducing project costs, and effectively mitigating the risk of large floating cranes hitting the bottom in shallow water, thus improving construction safety. Additionally, each adjustment function is implemented by an independent mechanism, resulting in a high degree of structural modularity, facilitating functional upgrades or modifications according to project requirements, and providing excellent flexibility.

Detailed Implementation

[0041] The core of this application is to provide a pile driving positioning auxiliary support to improve the pile driving construction accuracy when using a bottom-sitting vessel.

[0042] Another core aspect of this application is to provide a positioning method applicable to the aforementioned pile driving positioning auxiliary support.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] With the rapid development of offshore wind power, offshore photovoltaic and other marine engineering projects, increasingly higher requirements are being placed on the construction precision of underwater foundation structures. For example, in the construction of photovoltaic power stations in shallow sea areas, multiple steel pipe piles are often used as the supporting foundation for the upper platform. Since the leg spacing of the upper truss structure or grid structure is fixed, the construction precision of the steel pipe piles must meet the requirements of docking. This requires that the driving position and verticality of each steel pipe pile must be precisely controlled.

[0045] Traditional offshore steel pipe pile driving construction typically employs a large floating crane vessel in conjunction with a positioning frame. However, this method utilizes a bottom-sitting positioning frame, which is quite heavy, leading to high costs. Furthermore, the positioning frame requires a large lifting radius, placing significant demands on the floating crane itself. Additionally, offshore photovoltaic projects are usually conducted in shallow waters, and the large draft of the floating crane vessel poses a risk of bottoming out. In contrast, bottom-sitting vessels have a shallow draft, offering a natural advantage in shallow water operations and effectively reducing costs and risks. However, once bottom-sitting vessels are seated, their hull attitude can be affected by the unevenness of the seabed, causing them to tilt, and their positioning may also deviate slightly.

[0046] Therefore, such as Figure 1 As shown in the illustration, this application discloses a pile driving positioning auxiliary support 100, including an outrigger assembly 10, a horizontal adjustment mechanism 20, a position adjustment mechanism 30, and an angle adjustment mechanism 40. The first horizontal adjustment component 21 and the second horizontal component of the horizontal adjustment mechanism 20 constitute a two-stage leveling system for coarse and fine adjustment, effectively compensating for the large pitch attitude deviation of the hull-mounted vessel 200 caused by uneven seabed, and achieving high-precision leveling of the positioning frame 12. Simultaneously, combined with the first position adjustment component 31 positioning along the first direction of the hull-mounted vessel 200, the second position adjustment component 32 positioning along the second direction of the hull-mounted vessel 200, and the angle adjustment mechanism 40 for azimuth angle positioning, comprehensive compensation for the translational and rotational degrees of freedom of the pile body 300 in three-dimensional space is achieved. This effectively overcomes the positional deviation of the hull-mounted vessel 200, ensuring high precision in pile driving operations and exhibiting strong adaptability. Furthermore, the pile driving positioning auxiliary support 100 enables the low-cost bottom-sitting vessel 200 to handle high-precision pile driving tasks, avoiding reliance on expensive large floating crane vessels, significantly reducing project costs, and effectively mitigating the risk of large floating crane vessels hitting the bottom in shallow water, thus improving construction safety. Meanwhile, each adjustment function is implemented by an independent mechanism, resulting in a high degree of structural modularity, facilitating functional upgrades or modifications according to project needs, and providing excellent flexibility.

[0047] The following will combine Figures 1 to 6 The pile driving positioning auxiliary support 100 disclosed in the embodiments of this application will be explained and described in detail.

[0048] like Figure 1 and Figure 2As shown, the cantilever frame assembly 10 can extend outward from the bottom-sitting vessel 200, that is, the cantilever frame assembly 10 can be disposed on one side of the bottom-sitting vessel 200, and the cantilever frame assembly 10 can include a support frame 11 and a positioning frame 12. The support frame 11 serves as the base of the entire pile driving positioning auxiliary support 100, mainly bearing the weight of the positioning frame 12 above and the pile body 300. The support frame 11 can be connected to the bottom-sitting vessel 200, and the positioning frame 12 is rotatably mounted on the support frame 11 so that the pile body 300 can be positioned via the positioning frame 12.

[0049] In some embodiments, such as Figure 1 and Figure 2 As shown, the support frame 11 can be composed of two layers of first rectangular plane supports, and the opposite sides of the two first rectangular plane supports can be connected by multiple first vertical connecting rods and first diagonal braces to form a spatial truss structure system, thereby improving the support strength and stability of the support frame 11, and reducing the overall weight of the pile driving positioning auxiliary support 100.

[0050] In some embodiments, such as Figures 1 to 4 As shown, the positioning frame 12 can be composed of a double-layered second rectangular planar support, and the opposite sides of the two second rectangular planar supports can be connected by multiple second vertical connecting rods to form a spatial truss structure system, thereby improving the strength and stability of the positioning frame 12 and reducing the overall weight of the pile driving positioning auxiliary support 100. Furthermore, reinforcing rods can be connected between adjacent sides of the second rectangular planar support to improve the strength of the positioning frame 12. Support legs can be provided at the four corners of the positioning frame 12 to support it on the support frame 11, and second diagonal braces can be connected between the support legs and the sides of the lower second rectangular planar support to improve the support strength of the support legs and ensure the stability of the positioning frame 12.

[0051] It should be noted that both the first and second rectangular planar supports can consist of four side rods and two mutually perpendicular center rods. The four side rods can be welded together to form a rectangular planar frame. Simultaneously, the two mutually perpendicular center rods can be welded between the two opposite side rods to improve the strength and stability of the rectangular planar frame. Alternatively, the two center rods can be cross-welded to opposite corners of the rectangular planar frame to form a triangular stable support, further enhancing the strength and stability of the rectangular planar frame.

[0052] like Figure 1 and Figure 3As shown, the leveling mechanism 20 may include a first leveling component 21 and a second leveling component 22. The first leveling component 21 can adjust the pitch attitude of the outrigger assembly 10 relative to the bottom-sitting vessel 200 to perform preliminary leveling of the outrigger assembly 10. The second leveling component 22 can be disposed between the support frame 11 and the positioning frame 12, thereby adjusting the level of the positioning frame 12 relative to the support frame 11 to ensure that the positioning frame 12 meets the leveling requirements.

[0053] In some embodiments, such as Figure 1 and Figure 2 As shown, the first leveling assembly 21 may include support columns 211 and traction members 212. Two, three, or more support columns 211 may be used, and the traction members 212 are adapted to the support columns 211, meaning that the number of traction members 212 is the same as the number of support columns 211 (two, three, or more). The support columns 211 can be welded to the hull-mounted vessel 200, and the traction members 212 are adjustablely connected to the support columns 211. Simultaneously, the traction members 212 can be hinged to the support frame 11, so that the pitch attitude of the outrigger assembly 10 relative to the hull-mounted vessel 200 can be adjusted by adjusting the length of the traction members 212.

[0054] In some embodiments, the traction member 212 may be a flexible traction member such as a wire rope or steel cable, and a pulley may be provided at the top of the support column 211. One end of the traction member 212 may be hinged to the support frame 11, while the other end of the traction member 212 may pass around the pulley and be wound onto the winch of the bottom-sitting boat 200, so that the traction member 212 can be wound up and down by the winch, thereby adjusting the length of the traction member 212, and thus realizing the adjustment of the pitch attitude of the outrigger assembly 10 relative to the bottom-sitting boat 200.

[0055] In some embodiments, such as Figure 1 and Figure 2 As shown, two support columns 211 can be used, and each support column 211 can be provided with two traction members 212. At the same time, one end of the two traction members 212 is connected to two side rods of the first rectangular plane bracket on the upper layer of the support frame 11, which are arranged opposite to each other and parallel to the length direction of the bottom boat 200. The other end of the two traction members 212 can pass around the pulley and be wound around the winch of the bottom boat 200 at an angle with the support column 211. The angle between the traction member 212 and the support column 211 can be 30°, 45°, etc., to ensure the stability of the pitch attitude of the adjustable outrigger assembly 10 relative to the bottom boat 200.

[0056] In the above embodiments, the traction member 212 can also be a rigid traction member such as a telescopic rod, and the fixed end of the telescopic rod can be installed on the support column 211, while the movable end of the telescopic rod can be hinged to the support frame 11, so as to adjust the pitch attitude of the outrigger assembly 10 relative to the bottom boat 200 by extending or shortening the telescopic rod.

[0057] In some embodiments, such as Figure 3 As shown, the second horizontal adjustment assembly 22 may include an adjustment seat 221, and the adjustment seat 221 may be movably connected to the support leg located at the corner of the positioning frame 12 so that it can be supported on the support frame 11 through the adjustment seat 221.

[0058] In some embodiments, such as Figure 3 As shown, the adjusting seat 221 can be threaded into the support leg of the positioning frame 12, so that by rotating the adjusting seat 221, the positioning frame 12 can be moved away from or closer to the support frame 11, thereby adjusting the levelness of the positioning frame 12. Alternatively, one of the adjusting seat 221 and the positioning frame 12 can be provided with multiple adjusting holes, and the other with mounting holes that mate with the adjusting holes. That is, two, three, or more adjusting holes can be spaced vertically on the support leg of the positioning frame 12, and mounting holes that mate with the adjusting holes can be provided on the adjusting seat 221. The adjusting seat 221 can be sleeved on the outside of the support leg of the positioning frame 12. When the adjusting seat 221 is adjusted to the target position, the mounting hole can be aligned with the adjusting hole, allowing fasteners such as bolts to pass through the mounting hole and the adjusting seat in sequence. The adjusting seat 221 and the positioning frame 12 are locked together. Alternatively, two, three, or more adjusting holes can be spaced vertically on the adjusting seat 221, and mounting holes that mate with the adjusting holes can be provided on the support legs of the positioning frame 12. The adjusting seat 221 can be inserted into the support legs of the positioning frame 12. When the adjusting seat 221 is adjusted to the target position, the mounting holes can be aligned with the adjusting holes, allowing fasteners such as bolts to pass through the mounting holes and adjusting holes in sequence to lock the adjusting seat 221 and the positioning frame 12 together. It should be noted that the adjusting holes in the above embodiments can be threaded holes, and the mounting holes can be plain holes, so that fasteners such as bolts can pass through the mounting holes and connect with the threaded connection of the adjusting holes. Of course, the adjusting holes can also be plain holes, and the mounting holes can be threaded holes, which will not be elaborated further here.

[0059] In some embodiments, such as Figure 3 As shown, in order to reduce the resistance when the positioning frame 12 rotates relative to the support frame 11, an arc-shaped support surface 2211 can be provided on the contact side between the adjusting seat 221 and the support frame 11, so that the adjusting seat 221 can be supported on the support frame 11 through the arc-shaped support surface 2211, thereby reducing the friction force when the positioning frame 12 rotates and ensuring the stability of the positioning frame 12 when rotating relative to the support frame 11.

[0060] like Figure 1 and Figure 2 As shown, the position adjustment mechanism 30 may include a first position adjustment component 31 and a second position adjustment component 32. The first position adjustment component 31 can adjust the position of the outrigger assembly 10 relative to the bottom-sitting vessel 200 in a first direction, while the second position adjustment component 32 can be disposed on the positioning frame 12 and can adjust the position of the target pile 300 relative to the bottom-sitting vessel 200 in a second direction. It should be noted that the first direction is perpendicular to the length direction of the bottom-sitting vessel 200, and the second direction is parallel to the length direction of the bottom-sitting vessel 200.

[0061] In some embodiments, such as Figure 1 and Figure 2 As shown, the first position adjustment component 31 may include multiple first telescopic components 311 and a first telescopic drive member 312 adapted to the first telescopic components 311. That is, two, three or more first telescopic components 311 may be used, and each first telescopic component 311 is correspondingly provided with a first telescopic drive member 312. At the same time, at least one first telescopic component 311 can connect the support frame 11 and the bottom boat 200. That is, the support frame 11 and the bottom boat 200 can be connected by one, two or more first telescopic components 311, and the first telescopic drive member 312 can drive the first telescopic component 311 to extend or shorten in a first direction, so as to adjust the position of the outer frame component 10 relative to the bottom boat 200 in the first direction.

[0062] In some embodiments, such as Figure 1 and Figure 2 As shown, the first telescopic assembly 311 may include a first slide rail 3111 and a first slide rod 3112 that can slide along the first slide rail 3111. The first slide rail 3111 may have a tubular structure, and the first slide rod 3112 may pass through the inner cavity of the first slide rail 3111 and slide along it. The first slide rod 3112 may be connected to the support frame 11. A first telescopic drive member 312 may be installed on the first slide rail 3111, and the movable end of the first telescopic drive member 312 is connected to the first slide rod 3112. Thus, the first telescopic drive member 312 can drive the first slide rod 3112 to slide along the first slide rail 3111, thereby causing the support frame 11 to move towards or away from the bottom-sitting boat 200, thereby adjusting the position of the outrigger assembly 10 relative to the bottom-sitting boat 200 in a first direction. Meanwhile, at least one first slide 3111 of the first telescopic component 311 can be hinged to one side of the bottom-mounted boat 200 to ensure that the first horizontal adjustment component 21 can adjust the pitch attitude of the outrigger component 10 relative to the bottom-mounted boat 200.

[0063] In some embodiments, such as Figure 1 and Figure 2 As shown, four first telescopic components 311 can be used, and two first telescopic components 311 can be connected to two side rods of the upper first rectangular planar support of the support frame 11 along the first direction, and two first telescopic components 311 can be connected to two side rods of the lower first rectangular planar support of the support frame 11 along the first direction. The first slide rails 3111 of the two first telescopic components 311 connected to the upper first rectangular planar support can be hinged to one side of the hull-mounted boat 200. The first slide rails 3111 of the upper two first telescopic components 311 can be connected and fixed to the first slide rails 3111 of the lower two first telescopic components 311 via oblique connecting rods and vertical connecting rods. The first sliding rods 3112 of the first telescopic component 311 can be welded to the side rods of the first rectangular planar support to ensure the stability of the first telescopic component 311 in adjusting the position of the outrigger assembly 10 relative to the hull-mounted boat 200 in the first direction.

[0064] In the above embodiments, the first telescopic drive 312 may be a telescopic cylinder, a telescopic hydraulic cylinder, or a lead screw motor, etc., which are not limited here.

[0065] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the pile driving positioning auxiliary support may also include a pile clamping device 50, which can clamp or release the pile body 300. When the pile clamping device 50 clamps the pile body 300, the position of the pile clamping device 50 relative to the bottom-sitting vessel 200 in the second direction can be adjusted by the second position adjustment component 32, thereby adjusting the position of the pile body 300 relative to the bottom-sitting vessel 200 in the second direction.

[0066] In some embodiments, such as Figure 2 and Figure 4 As shown, in order to accommodate the construction of multiple piles 300 in a photovoltaic power station, multiple pile clamping devices 50 can be used, that is, three, four or more pile clamping devices 50 can be used to achieve simultaneous pile driving operations on multiple piles 300. The pile clamping device 50 may include an openable clamping hoop 51 and an opening / closing drive component 52 that can drive the clamping hoop 51 to perform opening and closing actions. The clamping hoop 51 has a clamping surface 511 that can fit against the pile 300 to ensure that the clamping hoop 51 can more stably clamp the pile 300 and prevent damage to the pile 300.

[0067] In some embodiments, such as Figure 5 and Figure 6As shown, the clamp 51 may include a fixed arm 512 and a movable arm 513. The fixed arm 512 has a first arc-shaped contact surface that can conform to the pile body 300, and is connected to the second position adjustment component 32. Two movable arms 513 may be used, each having a second arc-shaped contact surface that can conform to the pile body 300, allowing the second and first arc-shaped contact surfaces to be joined to form a clamping surface 511. One end of each movable arm 513 can be hinged to both ends of the fixed arm 512, allowing the other ends of the two movable arms 513 to rotate in directions that bring them closer together or further apart, thereby clamping or releasing the pile body 300. An opening / closing drive 52 can be connected to the fixed arm 512 via a connector, and the movable end of the opening / closing drive 52 can be connected to the movable arm 513 via a connector, allowing the opening / closing drive 52 to drive the movable arm 513 to rotate, thus clamping or releasing the pile body 300.

[0068] In some embodiments, such as Figure 5 and Figure 6 As shown, the clamp 51 can have a square outline. The fixed arm 512 can be composed of a corner of the square structure and two sides connected to the corner. The two movable arms 513 can be composed of the other sides of the square structure. The second position adjustment component 32 can be connected to the corner of the fixed arm 512. One end of the connector can be welded to the outside of the fixed arm 512 or the outside of the movable arm 513. The opening and closing drive component 52 can be hinged to the other end of the connector of the fixed arm 512, and the movable end of the opening and closing drive component 52 can be hinged to the other end of the connector of the movable arm 513. This allows the movable arm 513 to rotate through the opening and closing drive component 52, thereby clamping or releasing the pile body 300.

[0069] In some embodiments, such as Figure 3 and Figure 4 As shown, eight pile-holding devices 50 can be used, and four pile-holding devices 50 can be installed on the second rectangular plane support of each layer of the positioning frame 12. Each pile-holding device 50 can be located at a corner of the positioning frame 12. The four pile-holding devices 50 on each layer of the second rectangular plane support can be respectively positioned on the extension lines of the side rods of the second rectangular plane support that are opposite each other and parallel to the length direction of the bottom-sitting vessel 200 (i.e., the second direction). Furthermore, the distance between the pile-holding devices 50 on the extension lines of the side rods of the second rectangular plane support that are opposite each other and parallel to the length direction of the bottom-sitting vessel 200 can be adapted to the leg spacing of the upper truss structure (or space frame structure) to ensure that the construction accuracy of the pile 300 meets the docking requirements. Simultaneously, each pile 300 can be clamped or released by the pile-holding devices 50 located on the upper and lower layers of the second rectangular plane support, ensuring the stability of the pile driving and the reliability of the clamping.

[0070] In the above embodiments, the opening and closing drive component 52 may be a telescopic cylinder, a telescopic hydraulic cylinder, or a lead screw motor, etc., which are not limited here.

[0071] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the second position adjustment component 32 can be adapted to the pile clamping device 50, that is, each pile clamping device 50 corresponds to one second position adjustment component 32. Thus, the position of the pile clamping device 50 relative to the hull-mounted vessel 200 in the second direction can be adjusted via the second position adjustment component 32, thereby adjusting the position of the pile body 300 relative to the hull-mounted vessel 200 in the second direction. The second position adjustment component 32 may include a second telescopic component 321 and a second telescopic drive member 322 adapted to the second telescopic component 321. The second telescopic component 321 can connect the positioning frame 12 and the pile clamping device 50, while the second telescopic drive member 322 can drive the second telescopic component 321 to extend or retract in the second direction, thereby adjusting the position of the pile clamping device 50 relative to the hull-mounted vessel 200 in the second direction.

[0072] In some embodiments, such as Figure 5 and Figure 6 As shown, the second telescopic component 321 may include a second slide rail 3211 and a second slide rod 3212 that can slide along the second slide rail 3211. The second slide rail 3211 may have a tubular structure, and its side rods, which are opposite to the second rectangular planar support and parallel to the length direction (second direction) of the bottom-sitting vessel 200, can be fixed by welding. The second slide rod 3212 can pass through the inner cavity of the second slide rail 3211 and can slide along it. The second slide rod 3212 can be welded to the fixed arm 512 of the pile-holding device 50. The second telescopic drive member 322 can be installed on the second slide rail 3211, and its movable end is connected to the second slide rod 3212. Thus, the second slide rod 3212 can be driven to slide along the second slide rail 3211 by the second telescopic drive member 322, thereby causing the pile-holding device 50 to move relative to the bottom-sitting vessel 200 in the second direction, thereby adjusting the position of the pile body 300 relative to the bottom-sitting vessel 200 in the second direction.

[0073] In the above embodiments, the second telescopic drive 322 may be a telescopic cylinder, a telescopic hydraulic cylinder, or a lead screw motor, etc., which are not limited here.

[0074] like Figure 1 and Figure 2As shown, the angle adjustment mechanism 40 can be set between the support frame 11 and the positioning frame 12, and the angle adjustment mechanism 40 can drive the positioning frame 12 to rotate in the horizontal plane relative to the support frame 11, so as to adjust the direction angle of the positioning frame 12, thereby making the pile body 300 on the positioning frame 12 meet the direction angle requirements.

[0075] In some embodiments, such as Figure 1 and Figure 2 As shown, the angle adjustment mechanism 40 may include at least one rotary drive member 41, that is, one, two or more rotary drive members 41 may be used, and the rotary drive member 41 is hinged to the support frame 11. At the same time, the movable end of the rotary drive member 41 is connected to the positioning frame 12 so that the rotary drive member 41 can drive the positioning frame 12 to rotate relative to the support frame 11.

[0076] In some embodiments, such as Figure 2 and Figure 3 As shown, the rotary drive 41 can be a telescopic cylinder or a telescopic hydraulic cylinder, and the center position of the positioning frame 12 can be rotatably connected to the center position of the support frame 11 via the rotating shaft 121, so that the positioning frame 12 can rotate around the rotating shaft 121. At the same time, the movable end of the rotary drive 41 can be connected to the second horizontal adjustment component 22 on the positioning frame 12, so that the extension or shortening of the rotary drive 41 can drive the positioning frame 12 connected to the second horizontal adjustment component 22 to rotate around the rotating shaft 121.

[0077] In some embodiments, such as Figure 2 As shown, on the upper layer of the support frame 11, two side rods of the first rectangular planar support are arranged opposite each other and parallel to the length direction of the bottom-sitting boat 200 (i.e., the second direction). On their opposite sides, mounting brackets for mounting the rotary drive component 41 can be fixed. Four mounting brackets can be used, each located at one end of a side rod. Simultaneously, one rotary drive component 41 can be used, with its fixed end hinged to one of the mounting brackets. The movable end of the rotary drive component 41 can be connected to the second horizontal adjustment assembly 22 on the positioning frame 12. This allows the rotation of the positioning frame 12, connected to the second horizontal adjustment assembly 22, around the rotation axis 121 by extending or shortening the rotary drive component 41.

[0078] In some embodiments, such as Figure 2As shown, two rotary drive components 41 can be used, and the fixed ends of the two rotary drive components 41 can be hinged to the mounting brackets at opposite corners of the upper first rectangular planar support. Simultaneously, the movable ends of the rotary drive components 41 can be connected to the second horizontal adjustment assembly 22 at opposite corners on the positioning frame 12. The movable ends of the two rotary drive components 41 can extend or shorten in opposite directions to drive the positioning frame 12, connected to the second horizontal adjustment assembly 22, to rotate around the rotation axis 121. Of course, three or four rotary drive components 41 can also be used to increase the rotational power of the positioning frame 12, thereby ensuring the stability of the rotation of the positioning frame 12. This is not limited here.

[0079] The pile driving positioning auxiliary support 100 disclosed in this application embodiment can adjust the pitch attitude of the outrigger assembly 10 relative to the bottom-sitting vessel 200 after the bottom-sitting vessel 200 is in place, so as to initially adjust the levelness of the outrigger assembly 10. The levelness of the positioning frame 12 relative to the support frame 11 can be adjusted by the second level adjustment component 22 so that the positioning frame 12 meets the levelness requirements. At the same time, the position of the outrigger assembly 10 relative to the bottom-sitting vessel 200 in the first direction can be adjusted by the first position adjustment component 31, and the position of the target pile 300 relative to the bottom-sitting vessel 200 in the second direction can be adjusted by the second position adjustment component 32. The positioning frame 12 can be driven to rotate in the horizontal plane by the angle adjustment mechanism 40 so that the pile 300 on the positioning frame 12 meets the direction angle requirements.

[0080] The pile driving positioning auxiliary support 100 disclosed in this application, through the first horizontal adjustment component 21 and the second horizontal component of the horizontal adjustment mechanism 20, can form a two-stage leveling system of coarse and fine adjustment. This effectively compensates for the large pitch attitude deviation of the hull-sitting vessel 200 caused by uneven seabed and achieves high-precision leveling of the positioning frame 12. Simultaneously, combined with the first position adjustment component 31 positioning along the first direction of the hull-sitting vessel 200, the second position adjustment component 32 positioning along the second direction of the hull-sitting vessel 200, and the angle adjustment mechanism 40 for azimuth angle positioning, comprehensive compensation for the translational and rotational degrees of freedom of the pile body 300 in three-dimensional space is achieved. This effectively overcomes the positional deviation of the hull-sitting vessel 200, ensuring high precision in pile driving operations and exhibiting strong adaptability. Furthermore, the pile driving positioning auxiliary support 100 enables the hull-sitting vessel 200, with its lower operating costs, to undertake high-precision pile driving tasks, avoiding reliance on expensive large floating cranes, significantly reducing project costs, and effectively mitigating the risk of large floating cranes hitting the bottom in shallow water, thus improving construction safety. Meanwhile, each adjustment function is implemented by an independent mechanism, with a high degree of modularity, which facilitates functional upgrades or modifications according to engineering needs and provides good flexibility.

[0081] This application also discloses a positioning method applicable to the pile driving positioning auxiliary support 100 disclosed in the above embodiments. Therefore, it possesses all the technical effects of the aforementioned pile driving positioning auxiliary support 100, which will not be repeated here. The positioning method may include the following steps:

[0082] Step A: After the hull-mounted boat 200 is in place, the pitch attitude of the outrigger assembly 10 relative to the hull-mounted boat 200 is adjusted by the first leveling adjustment component 21 to make preliminary adjustments to the levelness of the outrigger assembly 10. Specifically, the outrigger assembly 10 can be adjusted to a roughly horizontal state by operating the winch and raising / lowering the traction component 212.

[0083] Step B involves adjusting the position of the cantilever assembly 10 relative to the hull-mounted vessel 200 in a first direction using the first position adjustment component 31. Specifically, the hydraulic system can be operated to drive the first telescopic drive member 312 of the first position adjustment component 31 to extend or shorten, thereby translating the entire cantilever assembly 10 in the width direction of the hull-mounted vessel 200, i.e., the first direction, to adjust it to the lateral coordinate of the designed pile position.

[0084] Step C involves adjusting the level of the positioning frame 12 relative to the support frame 11 using the second leveling adjustment component 22, so that the positioning frame 12 meets the leveling requirements. Specifically, according to the indication of the high-precision level, the elevation of the four corners below the positioning frame 12 can be adjusted using the second leveling adjustment component 22 until the positioning frame 12 is completely level, thus meeting the leveling requirements.

[0085] Step D involves driving the positioning frame 12 to rotate in the horizontal plane via the angle adjustment mechanism 40, so that the positioning frame 12 meets the orientation angle requirements. Specifically, the rotation drive 41 is operated to drive the positioning frame 12 to rotate around the rotation axis 121, so that the positioning frame 12 rotates to the design-required orientation.

[0086] Step E involves adjusting the position of the target pile 300 relative to the bottom-sitting vessel 200 in the second direction using the second position adjustment component 32. Specifically, the second telescopic drive component 322 is operated to move the pile-holding device 50 along the length direction of the bottom-sitting vessel 200, i.e., the second direction, to the longitudinal coordinate of the designed pile position.

[0087] It should be noted that after the position of the pile body 300 is determined, the clamp 51 can be opened by the opening and closing drive component 52, and the pile body to be driven, which has been placed on the bottom-sitting vessel 200, can be lifted into the clamp 51 by the lifting equipment on the bottom-sitting vessel 200. Then, the clamp 51 can be closed by the opening and closing drive component 52 to clamp the pile body to be driven, and the subsequent pile driving operation can begin.
