Description

Technical Field

[0001] This application relates to the field of offshore piling technology, and in particular to piling auxiliary devices and their working methods. Background Technology

[0002] As the global energy structure shifts towards clean energy, marine engineering projects such as offshore wind power and deep-sea oil and gas development are continuously advancing into deep-sea areas. Among these projects, deep-sea piling operations serve as the foundation of marine engineering, and the piling of columns requires the use of piling auxiliary devices to help fix the columns.

[0003] CN119843661A discloses a marine precision positioning piling device, including a support body, a piling component, a position adjustment assembly, and a limiting assembly. The piling component is disposed inside the support body. The position adjustment assembly includes multiple position adjustment components connected to the support body and the piling component. The limiting assembly includes multiple limiting components connected to the position adjustment components and the piling component. The position adjustment components work in coordination to adjust the horizontal position of the piling component, and the multiple limiting components are used to adjust the horizontal rotation angle of the piling component. Due to the unevenness of the seabed, the piling device may tilt. Even after adjusting the angle of the piling component relative to the horizontal plane, it will still tilt, affecting the verticality of the subsequent pile.

[0004] In addition, after being deployed to the seabed, the piling device stands upright on the ground using its own weight. However, the currents on the seabed are complex, and the device may move due to the impact of seawater and the buoyancy of the seawater. This will affect the accuracy of the piling position in the later stages. Summary of the Invention

[0028] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0029] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0030] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0031] refer to Figures 1 to 6 The piling auxiliary device according to a preferred embodiment of this application will be described in detail below.

[0032] refer to Figure 1 and Figure 2 The piling auxiliary device includes a main body 10, multiple adjustment mechanisms 20, a fixing mechanism 30, and a guide column assembly 40.

[0033] The main body 10 of the device includes multiple support columns 11 and a mounting body 12. The support columns 11 are installed at intervals on the mounting body 12, and the support columns 11 support the mounting body 12 at a predetermined height.

[0034] refer to Figure 4 The guide post assembly 40 includes a support member 41 that forms an inlet 4101. When the support member 41 is horizontal, the inlet 4101 extends axially in the vertical direction, allowing the post to pass through.

[0035] Multiple adjustment mechanisms 20 are spaced apart along the circumference of the inlet 4101, and each adjustment mechanism 20 is connected at both ends to the mounting body 12 and the support member 41, respectively. The adjustment mechanism 20 is configured to move the support member 41 to calibrate the support member 41 so that the axis of the inlet 4101 extends vertically and is aligned with the center of the piling position. Thus, the inlet 4101 formed by the support member 41 can limit the vertical extension of the pile and prevent the pile from tilting during piling, ensuring that the pile is accurately inserted into the piling position vertically.

[0036] refer to Figure 2 and Figure 3 The fixing mechanism 30 is installed on the main body 10 of the device and is configured to drive the support column 11 into the soil layer. After the fixing mechanism 30 drives the support column 11 into the soil layer, the piling auxiliary device is firmly connected to the foundation, so that the piling auxiliary device can remain stable even underwater, preventing the piling auxiliary device from moving due to the impact of seawater, etc., thereby reducing the deviation between the piling auxiliary device and the preset placement position, reducing the difficulty of subsequent calibration, thereby improving the accuracy of column placement, and preventing the piling auxiliary device from moving during piling, ensuring the stability of piling and the verticality of the column.

[0037] Preferably, multiple fixing mechanisms 30 are provided, and the multiple fixing mechanisms 30 are installed at intervals on the main body 10 of the device so that multiple support columns 11 extend into the soil layer evenly, thereby improving the balance of the pile driving auxiliary device.

[0038] In one embodiment, each of the support columns 11 forms an assembly channel 1101, and the end of each support column 11 away from the mounting body 12 also forms an inlet / outlet 1102 communicating with the assembly channel 1101. The fixing mechanism 30 includes a drill bit 31, a pressure applying component 32, and a drive component 33. The pressure applying component 32 and the drive component 33 are both installed in the assembly channel 1101, wherein the drive component 33 is connected to the pressure applying component 32, the drill bit 31 is connected to the drive component 33, and the drill bit 31 extends out of the assembly channel 1101 from the inlet / outlet 1102. The drive component 33 is used to drive the drill bit 31 to rotate, and the pressure applying component 32 is used to drive the drive component 33 to move vertically. Once the piling auxiliary device is in place, the pressure-applying component 32 drives the drill bit 31 to rotate, causing the drill bit 31 to cut through the soil layer. At the same time, the pressure-applying component 32 drives the rotating component 33 to move downward, so that the drill bit 31 presses down on the soil layer, causing the drill bit 31 to drill into the foundation and drive the support column 11 to insert into the foundation, thereby establishing a connection between the piling auxiliary device and the foundation.

[0039] As an example, the pressure-applying component 32 is implemented as a cylinder; the drive component 33 is implemented as including a motor.

[0040] Preferably, the fixing mechanism 30 further includes a vibration component 34, which is connected to the pressure application component 32 and the drive component 33. The vibration component 34 drives the drill bit 31 to vibrate vertically, causing the drill bit 31 to crush the foundation. In this way, the drill bit 31 can break hard soil layers and rocks under the drive of the vibration component 34, thus making the piling auxiliary device suitable for various geological conditions.

[0041] As an example, the vibration component 34 is implemented as a vibratory hammer.

[0042] Preferably, the fixing mechanism 30 further includes a guide structure 35, which includes a guide protrusion 351 and a sliding groove 352. Either the guide protrusion 351 or the sliding groove 352 is formed on the inner wall of the assembly channel 1101, and the other is formed on the outer peripheral wall of the driving component 33 and / or the vibrating component 34. The guide protrusion 351 is inserted into the sliding groove 352. The sliding groove 352 and the guide protrusion 351 cooperate to limit the vertical movement of the driving component 33, the vibrating component 34, and the drill bit 31.

[0043] Preferably, the fixing mechanism 30 further includes a seal 36, which is sealingly installed in the assembly channel 1101 and movable along the extension direction of the assembly channel 1101. The drill bit 31 is rotatably inserted into the seal 36, which seals the assembly channel 1101 to prevent seawater from entering the assembly channel 1101, thereby protecting the pressure-applying component 32, the driving component 33, and the vibrating component 34, and extending the service life of the fixing mechanism 30.

[0044] As an example, the seal 36 is implemented to include a sealing ring.

[0045] refer to Figure 4 Preferably, the mounting body 12 forms the through hole 1201 through which the pile passes. After the support member 41 is calibrated, the inlet 4101 and the through hole 1201 are coaxial. The pile passes through the inlet 4101 and the through hole 1201 in sequence, increasing the limiting position to reduce pile sway and improve the limiting effect of the pile driving auxiliary device on the pile.

[0046] refer to Figures 4 to 6 Specifically, each of the adjustment mechanisms 20 includes a telescopic member 21, a first floating connecting component 22, and a second floating connecting component 23. The telescopic member 21 includes a telescopic rod 211 and a cylinder 212, with the telescopic rod 211 telescopically inserted into the cylinder 212. One end of the first floating connecting component 22 is connected to the end of the telescopic rod 211 extending out of the cylinder 212, and the other end is connected to the support member 41. One end of the second floating connecting component 23 is connected to the end of the cylinder 212 away from the telescopic rod 211, and the other end is connected to the mounting body 12. When the telescopic member 21 extends or retracts, the second floating connecting component 23 causes the telescopic member 21 to swing relative to the mounting body 12 in any direction, and the first floating connecting component 22 causes the guide post assembly 40 to swing relative to the telescopic member 21 in any direction, thereby adjusting the angle and position of the support member 41.

[0047] In other words, when the support member 41 tilts, by controlling the extension and retraction of the corresponding telescopic member 21 to link the first floating connecting member 22 and the second floating connecting member 23, the support member 41 can be rotated to a horizontal position, so that the entrance 4101 formed by the support member 41 limits the movement of the pile in the vertical direction. Similarly, it can be understood that when the axis of the entrance 4101 formed by the support member 41 deviates from the center of the preset piling position, by controlling the extension and retraction of the telescopic member 21 to link the first floating connecting member 22 and the second floating connecting member 23, the support member 41 can be guided to move until the axis of the entrance 4101 is aligned with the center of the preset piling position, thereby calibrating the support member 41 and improving the accuracy of the piling position.

[0048] As an example, the telescopic member 21 is implemented to include an electric push rod.

[0049] Preferably, the first floating connecting component 22 includes a first mounting base 221, a second mounting base 222, and a rotating component 223. The first mounting base 221 is fixedly mounted on the support member 41, the second mounting base 222 is fixedly mounted on the telescopic rod 211, and the rotating component 223 is rotatably mounted on the first mounting base 221 and the second mounting base 222, such that the rotating component 223 can rotate relative to the first mounting base 221. When the telescopic member 21 extends or retracts, the second mounting base 222 drives the rotating component 223 to rotate relative to the first mounting base 221, causing the support member 41 to rotate relative to the telescopic member 21.

[0050] Furthermore, the rotating member 223 is rotatably mounted on the second mounting base 222, so that the rotating member 223 can also rotate relative to the second mounting base 222, thereby increasing the rotation angle range and / or rotation direction of the support member 41, and improving the flexibility of the adjustment mechanism 20 in adjusting the support member 41.

[0051] refer to Figure 6 In one embodiment, the rotating member 223 has two first ball heads 2231A and a first rod portion 2232A, with the two first ball heads 2231A respectively mounted at both ends of the first rod portion 2232A. The first mounting base 221 and the second mounting base 222 each form a first spherical groove 2201A, and the two first ball heads 2231A are rotatably mounted within the first spherical grooves 2201A formed by the first mounting base 221 and the second mounting base 222, respectively, so that the rotating member 223 can rotate in any direction relative to the first mounting base 221 and the second mounting base 222.

[0052] refer to Figure 5 In another embodiment, the rotating member 223 includes two first connecting shafts 2231 and a first mounting body 2232. Both first connecting shafts 2231 are inserted into the first mounting body 2232, and the axes formed by each of the two first connecting shafts 2231 extend horizontally. The first mounting base 221 and the second mounting base 222 are respectively connected to the two first connecting shafts 2231. The first mounting base 221 is rotatable about the axis of one first connecting shaft 2231, and the second mounting base 222 is rotatable about the axis of the other first connecting shaft 2231. Preferably, the axes formed by the two first connecting shafts 2231 are skew lines, thereby increasing the rotational direction of the support member 41.

[0053] Preferably, the second floating connection component 23 includes a first mounting base 231, a second mounting base 232, and a rotating member 233. The first mounting base 231 is fixedly mounted on the mounting body 12, the second mounting base 232 is fixedly mounted on the cylinder body 212, and the rotating member 233 is rotatably mounted on the first mounting base 231 and the second mounting base 232, such that the rotating member 233 can rotate relative to the first mounting base 231. When the telescopic member 21 extends or retracts, the second mounting base 232 can drive the rotating member 233 to rotate relative to the first mounting base 231, so that the telescopic member 21 drives the support member 41 to rotate relative to the mounting body 12.

[0054] Furthermore, the rotating member 233 is rotatably mounted on the second mounting base 232, so that the second mounting base 232 can rotate relative to the rotating member 233, thereby increasing the range of rotation angle and / or direction of rotation of the support member 41, and improving the flexibility of the adjustment mechanism 20 in adjusting the support member 41.

[0055] refer to Figure 6 In one embodiment, the rotating member 233 has two second ball heads 2331A and a second rod portion 2332A, with the two second ball heads 2331A respectively mounted at both ends of the second rod portion 2332A. Both the first mounting base 231 and the second mounting base 232 form a second spherical groove 2301A, and the two second ball heads 2331 are rotatably mounted within the respective second spherical grooves 2301A formed by the first mounting base 231 and the second mounting base 232, allowing the rotating member 233 to rotate in any direction relative to the first mounting base 231 and the second mounting base 232, thereby improving the flexibility of adjustment.

[0056] refer to Figure 5As a deformable configuration, the rotating member 233 includes two second connecting shafts 2331 and a second assembly body 2332. Both second connecting shafts 2331 are inserted into the second assembly body 2332, and the axes formed by each of the two second connecting shafts 2331 extend horizontally. The first mounting base 231 and the second mounting base 232 are respectively connected to the two second connecting shafts 2331. The first mounting base 231 is rotatable about the axis of one second connecting shaft 2331, and the second mounting base 232 is rotatable about the axis of the other second connecting shaft 2331. Preferably, the axes formed by the two second connecting shafts 2331 are skew lines, thereby increasing the rotational direction of the support member 41.

[0057] Furthermore, the guide post assembly 40 also includes a guide member 42, which is mounted on one end face of the support member 41 facing away from the mounting body 12, and forms the guide post channel 4201, which communicates with the inlet 4101. The inner diameter of the end of the guide post channel 4201 away from the inlet 4101 is much larger than the diameter of the post, so that the post can be aligned and inserted into the guide post channel 4201.

[0058] Preferably, the inner diameter of the guide member 42 near the end of the support member 41 gradually decreases from top to bottom, so as to facilitate the alignment of the guide post of the inner wall of the guide post channel 4201 with the inlet 4101.

[0059] Furthermore, the piling auxiliary device also includes a position detection mechanism 50. The position detection mechanism 50 includes a plurality of first position detection components 51, which are spaced apart and mounted on the support member 41 to obtain the three-dimensional positions of multiple locations on the support member 41, thereby measuring the three-dimensional position and attitude of the support member 41. The first position detection components 51 are communicatively connected to a controller 900 on the hull, and transmit the real-time pose of the support member 41 to the controller 900.

[0060] The telescopic component 21 is controllably connected to the controller 900, which controls the telescopic component 21 to extend and retract. After the support column 11 is inserted into the foundation, the first position detection component 51 detects the position of the support component 41. After the controller 900 obtains the position of the support component 41, it compares it with the preset position of the support component 41. The controller 900 controls the corresponding telescopic component 21 to extend and retract according to the position of the support component 41 and the preset position to calibrate the support component 41, so that the axis of the inlet 4101 is aligned vertically with the center of the preset piling position, ensuring that the column corresponds to the preset piling position, thereby improving the accuracy of piling.

[0061] As an example, the first position detection component 51 is implemented as an underwater acoustic transponder.

[0062] Preferably, the piling auxiliary device further includes multiple suspension members 60, each forming a hanging hole 601. The hook of the hoisting device on the hull is adapted to the hanging hole 601 formed by the suspension member 60, so that the piling auxiliary device is suspended from the hoisting equipment. The hoisting equipment is controllably connected to the controller 900, which controls the operation of the hoisting equipment according to a preset piling position, so that the hoisting equipment can lower the piling auxiliary device into the seabed.

[0063] Furthermore, the position detection mechanism 50 includes a plurality of second position detection components 52, which are spaced apart and mounted on the mounting body 12 to obtain the three-dimensional positions of multiple parts on the mounting body 12, thereby measuring the three-dimensional position and orientation of the mounting body 12. The second position detection components 52 are communicatively connected to the controller 900, and transmit the real-time orientation of the mounting body 12 to the controller 900.

[0064] In other words, the controller 900 controls the hoisting device to operate according to the preset piling position, thereby aligning the piling auxiliary device with the preset piling position. During the deployment of the piling auxiliary device, the controller 900 controls the hoisting device to operate according to the three-dimensional position of the installation body 12 detected by the second position detection component 52, and adjusts the position of the piling auxiliary device in a timely manner to improve the deployment accuracy. After the piling auxiliary device is deployed, the fixing mechanism 30 drives the support column 11 to extend into the foundation, reducing the movement of the piling auxiliary device due to seawater impact and ensuring the stability of the piling auxiliary device. Then, the controller 900 drives the corresponding telescopic component 21 to extend and retract according to the difference between the position of the support component 41 and the preset position, so as to calibrate the guide column assembly 40 and achieve fine adjustment, further improving the coaxiality of the inlet 4101 and the center of the preset piling position, so that the pile can finally fall accurately to the preset piling position.

[0065] As an example, the second position detection component 52 is implemented as an underwater acoustic transponder.

[0066] This application also provides a method for operating the aforementioned piling auxiliary device, including the following steps:

[0067] The controller 900 controls the operation of the hoisting device so that the hoisting device moves the piling auxiliary device closer to the preset piling position. During the deployment of the piling auxiliary device, the controller 900 controls the hoisting device to adjust the position of the piling auxiliary device based on the three-dimensional position of the installation body 12 obtained by the second position detection component 52.

[0068] After the piling auxiliary device is deployed, the fixing mechanism 30 drives the support column 11 to extend into the soil layer, so that the piling auxiliary device is firmly connected to the foundation.

[0069] Specifically, the pressure-applying component 32 drives the drill bit 31 to rotate, and at the same time, the pressure-applying component 32 drives the drive component 33 to move downward, so that the drill bit 31 drills into the foundation and drives the support column 11 to insert into the foundation.

[0070] Preferably, the vibrating component 34 drives the drill bit 31 to impact the soil layer, thereby breaking up hard soil layers and rocks.

[0071] After the support column 11 is inserted into the foundation, the controller 900 controls the corresponding telescopic member 21 to extend or retract according to the difference between the three-dimensional position and attitude of the support member 41 and the preset position, so as to calibrate the guide column assembly 40 and align the axis of the inlet 4101 with the center of the preset piling position in the vertical direction.

[0072] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application.
