Description

Technical Field

[0001] This application relates to the field of offshore piling technology, specifically to an offshore piling precision positioning auxiliary device and a piling vessel. Background Technology

[0002] Currently, offshore piling is a common engineering operation for providing stable support structures for floating buildings, such as bridges. Offshore piling ensures the long-term stability and safety of these structures in complex marine environments. However, when constructing bridges and other buildings on water, the piling operation of steel pipe piles is often affected by various adverse factors such as waves, which poses significant challenges to the precision control of the piling operation.

[0003] Chinese patent publication number CN214883659U discloses a marine precision positioning piling guide frame, which includes four columns, with reinforcing rods fixed between the columns. Two mounting rings are set between the four columns, and connecting rods are fixedly connected between the mounting rings and the side walls of the columns. Guide cylinders are connected to the mounting rings, and the upper end of the guide cylinders has a flared opening. An adjustable positioning mechanism is set at the bottom end of the columns. When different diameter foundation piles are required, the nuts can be unscrewed, the guide cylinders can be pulled out, and then guide cylinders with appropriate inner diameters can be inserted. The fixed column is then aligned and inserted into the fixing hole, and the nuts are fixed on the fixed column to complete the replacement. Replacement is simple and more adaptable. If a positioning column becomes suspended, the motor is started to drive the gear to rotate, which in turn drives the gear ring and the rotating ring to rotate, causing the lead screw to move downward, thereby moving the positioning column downward and inserting it into the seabed, thus stabilizing the equipment.

[0004] However, the marine precision positioning piling guide frame disclosed in the aforementioned patent still has some shortcomings in practical applications. For example, sometimes there are strong winds, waves, and currents near the piling location. When the device needs to insert its positioning column into the seabed, it will be completely exposed to the continuous impact of the wind, waves, and currents. However, since the device lacks pre-fixing means, it is easily pushed and deviated by external forces. Therefore, once these external forces cause the device to deviate, the positioning column of the device will also deviate synchronously in the direction of the force, thus causing the final insertion position of the positioning column to deviate from the original insertion position. This causes the pile foundation steel pipe pile to also deviate synchronously, thereby increasing the difficulty of precision control in the pile foundation steel pipe pile driving construction.

The preferred embodiments described below are only examples of the present application, and other obvious modifications can be made by those skilled in the art. The essential principles defined in the following description can be applied to other embodiments, modifications, improvements, equivalents and other technical solutions without departing from the spirit and scope of the present application.

[0026] It can be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of one element can be one, and in another embodiment, the number of the element can be multiple, and the term "one" cannot be understood as a limitation on the number.

[0027] Reference Figure 1 According to a preferred embodiment of the present application, the offshore pile driving precision positioning auxiliary device comprises a device body 10, a pile assembly 20, a self-weight adjusting assembly 30 and an anchoring assembly 40.

[0028] The pile assembly 20 is installed on the device body 10 to enhance the radial positioning effect of the pile body. The self-weight adjusting assembly 30 is used to adjust the self-weight of the device, balance external impact force, so as to avoid the inclination or deviation of the entire device.

[0029] Specifically, the pile assembly 20 comprises a pile member 21, wherein the pile member 21 is installed on the device body 10, and the pile member 21 further forms a pile passage 2101 penetrating the top surface and the bottom surface of the device body 10, the size of the pile passage 2101 is matched with the size of the pile body, that is, the inner wall of the pile passage 2101 is fitted to the surface of the pile body. It is worth mentioning that the pile body can be moved along the length direction of the pile passage 2101 by the pile driving mechanism to complete the pile driving operation. In this way, the pile member 21 realizes the radial positioning of the pile body.

[0030] The self-weight adjusting assembly 30 comprises a suction member 31, an adapter pipe 32 and at least one storage unit 33, wherein the suction member 31 is installed on the device body 10. The adapter pipe 32 has a first pipe portion 321 and at least one second pipe portion 322 in communication with the first pipe portion 321, wherein the first pipe portion 321 is in communication with the suction member 31, and one of the second pipe portions 322 is in communication with one of the storage units 33. Each of the storage units 33 is installed on the device body 10 to store a predetermined amount of liquid, so that when the suction member 31 is completely immersed in the liquid, the liquid guided by the suction member 31 flows through the adapter pipe 32 and is stored in the storage unit 33, or the liquid stored in the storage unit 33 flows through the adapter pipe 32 and is discharged.

[0031] It can be understood that when it is required to store liquid inside the storage unit 33, the suction member 31 is started to make the liquid immersed in the suction member 31 firstly sucked from the first pipe portion 321 of the adapter pipe 32, then flow through the second pipe portion 322, and finally be stored in the storage unit 33, at this time, the overall gravity of the offshore pile precise positioning auxiliary device is increased; and when it is required to discharge the liquid stored in the storage unit 33, the suction member 31 is started to make the liquid in the storage unit 33 firstly be sucked into the second pipe portion 322, then flow through the first pipe portion 321, and finally be discharged, at this time, the increased gravity of the offshore pile precise positioning auxiliary device is reduced.

[0032] It is worth mentioning that the first pipe portion 321 of the adapter pipe 32 and the suction member 31 are in sealed connection, that is, the liquid guided into the adapter pipe 32 through the suction member 31 cannot flow out from the position where the suction member 31 and the first pipe portion 321 are connected to each other. Similarly, the second pipe portion 322 of the adapter pipe 32 and the storage unit 33 are in sealed connection, that is, the liquid guided into the adapter pipe 32 through the suction member 31 cannot flow out from the position where the second pipe portion 322 and the storage unit 33 are connected to each other.

[0033] The anchoring assembly 40 comprises at least one first driving unit 41, at least one second driving unit 42 and at least one screw anchor 43, wherein at least one first driving unit 41 is mounted on the device body 10, and at least one screw anchor 43 is rotatably mounted on one first driving unit 41. At least one second driving unit 42 is mounted on the device body 10, and one second driving unit 42 is used to drive one screw anchor 43 to move in the upward or downward direction.

[0034] It can be understood that before the pile body is implemented to perform the penetration operation, the offshore pile precise positioning auxiliary device needs to be pre-positioned on the seabed, that is, the first driving unit 41 and the second driving unit 42 are simultaneously started to make each screw anchor 43 automatically perform the penetration operation towards the seabed, so that the offshore pile precise positioning auxiliary device is fixed on the seabed.

[0035] It is understood by those skilled in the art that when the pile body needs to be implemented into the penetration operation in the location where the wave impact force is large, the offshore pile driving precision positioning auxiliary device can increase its gravity through the self-weight adjusting assembly 30 to actively balance the wave impact force on the whole device in the pile body operation environment, thereby maintaining the overall posture of the whole device stable and preventing the whole device from tilting or deviating under the impact of the wave.

[0036] In addition, the offshore pile driving precision positioning auxiliary device also enables each screw anchor 43 to stably perform the penetration operation in the way of increasing the self-weight. In this way, the penetration position of each screw anchor 43 into the seabed remains unchanged from the originally planned penetration position, so that the pile body penetration position remains consistent with the originally planned penetration position, thereby improving the precision of the pile body penetration operation.

[0037] In one embodiment, as shown in Figures 1 to 3 The device body 10 includes a mounting plate 11 and two linkage arms 12, wherein the two linkage arms 12 are reversibly connected to the two sides of the mounting plate 11, and a size-adjustable opening is formed between the two linkage arms 12. The pile positioning member 21 includes two pile positioning arms 211, which are respectively mounted on the two linkage arms 12 and located in the opening, so that when the two linkage arms 12 are respectively rotated relative to the mounting plate 11 to keep close to each other, the two pile positioning arms 211 are also synchronously close to each other to combine to form the pile positioning channel 2101, at this time, the opening reaches the minimum, and the pile body is fitted by the two pile positioning arms 211, thereby achieving the purpose of radial positioning of the pile body.

[0038] It is worth mentioning that each pile positioning arm 211 can be mounted with a linkage arm 12 through bolts or other detachable connecting structures, thereby providing convenience for the operation of replacing the pile positioning arm 211.

[0039] Preferably, the pile positioning assembly 20 further includes a pile driving unit 22, wherein the pile driving unit 22 is mounted on the device body 10, and the pile driving unit 22 is used to drive the two linkage arms 12 to rotate, so that the two linkage arms 12 can relatively move close to and away from each other. In this way, the two pile positioning arms 211 can automatically combine to form the pile positioning channel 2101, thereby realizing the radial positioning of the pile body.

[0040] In one embodiment, the pile driving unit 22 is provided as two driving motors, and the two driving motors are mounted on the mounting plate 11, and the two driving motors are respectively used to drive the two linkage arms 12 to rotate, so that the two pile positioning arms 211 are close to and away from each other.

[0041] In another embodiment, as shown in Figures 1 to 3 The pile driving unit 22 includes a pile driving member 221 and a linkage member 222, wherein the pile driving member 221 is mounted to the mounting plate 11 and is configured to drive the linkage member 222. The linkage member 222 is configured to drive the two linkage arms 12 to move relatively close to and away from each other by being driven by the pile driving member 221, so as to adjust the size of the opening.

[0042] It is understood that when the linkage member 222 is driven by the pile driving member 221 to move the two linkage arms 12 close to each other, the pile passage 2101 is formed between the two pile arms 211 for the purpose of radial positioning of the pile.

[0043] Preferably, the linkage member 222 includes a driving rod 2221 and two passive rods 2222, wherein the driving rod 2221 is drivingly connected to the pile driving member 221 and is configured to move close to and away from the mounting plate 11 by being driven by the pile driving member 221. The two passive rods 2222 are respectively hinged to two ends of the driving rod 2221, and each passive rod 2222 is hinged to one linkage arm 12 away from the other end of the driving rod 2221.

[0044] It is noted that when the pile driving member 221 is activated to move the driving rod 2221 away from the mounting plate 11, the driving rod 2221 is synchronously driven to move a predetermined distance away from the mounting plate 11, and since the two ends of the driving rod 2221 are respectively hinged to the two passive rods 2222, and each passive rod 2222 is hinged to one linkage arm 12 away from the other end of the driving rod 2221, the two linkage arms 12 are driven to simultaneously rotate close to the mounting plate 11, and at this time, the two pile arms 211 remain close to each other to combine to form the pile passage 2101. When the pile driving member 221 is activated to move the driving rod 2221 close to the mounting plate 11, the driving rod 2221 is synchronously driven to move a predetermined distance close to the mounting plate 11, and since the two ends of the driving rod 2221 are respectively hinged to the two passive rods 2222, and each passive rod 2222 is hinged to one linkage arm 12 away from the other end of the driving rod 2221, the two linkage arms 12 are driven to simultaneously rotate away from the mounting plate 11, and at this time, the two pile arms 211 respectively follow the movement of the linkage arms 12 connected thereto to remain away from each other, so that the pile passage 2101 cannot be combined to completely fit the size of the pile. Figures 1 to 3 ​

[0045] Further preferably, the pile driving assembly 20 further comprises a fixing frame 23 fixedly connected to the mounting plate 11 for surrounding the pile driving member 221 so as to provide protection for the pile driving member 221.

[0046] As preferred, the pile driving member 221 is arranged to be connected to the middle portion of the driving rod 2221 for stably driving the two passive rods 2222. It is understood that the pile driving member 221 is implemented to comprise a waterproof telescopic device, such as a waterproof hydraulic cylinder, wherein the telescopic end of the hydraulic cylinder is arranged to penetrate through the fixing frame 23 and be connected to the middle portion of the driving rod 2221.

[0047] Preferably, the suction member 31 is implemented to comprise a circulating pump.

[0048] In one preferred embodiment, as shown in Figures 1 to 3 the adapter pipe 32 has two second pipe portions 322, and the number of the storage units 33 is arranged to be two, and the two storage units 33 are respectively installed on the two linkage arms 12 in a relative manner, and the two second pipe portions 322 of the adapter pipe 32 are respectively communicated with the two storage units 33.

[0049] Preferably, the adapter pipe 32 is installed on the mounting plate 11 of the device body 10. It is worth mentioning that the adapter pipe 32 can be arranged as a three-way pipe. In addition, the two second pipe portions 322 of the adapter pipe 32 both comprise a flexible waterproof material, such as a waterproof rubber material, and the like, so that when the two linkage arms 12 are driven to rotate, the two second pipe portions 322 can be bent by a predetermined amplitude to support the rotating action of the two linkage arms 12 respectively installed.

[0050] Further preferably, each linkage arm 12 is further provided with at least one limiting portion 121, and each limiting portion 121 is provided with a through passage penetrating through the body thereof for guiding the installation of the second pipe portion 322 of the adapter pipe 32, so as to limit the two second pipe portions 322 of the adapter pipe 32 from excessive swinging.

[0051] In one embodiment, each storage unit 33 is arranged to be a container made of a flexible waterproof material for storing liquid inside or discharging the liquid stored inside under the guidance of the suction member 31.

[0052] In one embodiment, as shown in Figure 1As shown, each storage unit 33 includes a plurality of air bladders 331, and the plurality of air bladders 331 in each storage unit 33 are in communication with each other. One of the air bladders 331 in each storage unit 33 is connected to a second tube portion 322 of the adapter tube 32 for storing liquid. That is, the suction member 31 can guide liquid into the plurality of air bladders 331 in each storage unit 33 through the adapter tube 32, or the suction member 31 can guide the liquid in the plurality of air bladders 331 to be discharged through the adapter tube 32.

[0053] It is worth mentioning that the two adjacent airbags 331 that are interconnected maintain a sealed connection to prevent liquid leakage, and the airbag 331 and the second tube 322 are also sealed to prevent liquid leakage. In addition, all airbags 331 are made of flexible waterproof material.

[0054] Preferably, each storage unit 33 further includes a plurality of sliding blocks 332 and at least one positioning rod 333, wherein the plurality of sliding blocks 332 of each storage unit 33 are slidably mounted on the outer periphery of at least one positioning rod 333 in a uniformly arranged manner, and the plurality of sliding blocks 332 of each storage unit 33 are respectively connected to a plurality of airbags 331. At least one positioning rod 333 of each storage unit 33 is mounted on the same linkage arm 12. In other words, one airbag 331 is connected to one sliding block 332, and at least one sliding block 332 is allowed to slide on each positioning rod 333.

[0055] It should be noted that, as Figure 1 As shown, multiple airbags 331 are evenly arranged vertically. When the storage unit 33 needs to store liquid, the multiple airbags 331 will cause their respective connected sliding blocks 332 to gradually slide upward along the axial direction of their corresponding positioning rods 333 as the amount of stored liquid increases. When the storage unit 33 needs to discharge the stored liquid, the multiple airbags 331 will discharge the stored liquid under the guidance of the suction member 31. At this time, the multiple airbags 331 will cause their respective connected sliding blocks 332 to gradually slide downward along the axial direction of their corresponding positioning rods 333. In this way, the multiple airbags 331 installed on each linkage arm 12 can adjust their weight evenly, thereby avoiding local weight imbalance.

[0056] Preferably, each of the linkage arms 12 has an installation window 1201 for mounting at least one of the positioning rods 333 of one of the storage units 33.

[0057] It is worth mentioning that each of the sliding blocks 332 is arranged in a ring shape to slide with the corresponding positioning rod 333.

[0058] In one embodiment, one of the screw anchors 43 is rotatably mounted on one of the first driving units 41, one of the first driving units 41 is movably mounted on the device body 10 by relative sliding, and one of the first driving units 41 is movably mounted on one of the second driving units 42. When the offshore pile driving precision positioning auxiliary device is fixed to the seabed, one of the second driving units 42 drives one of the first driving units 41 to move in the upward direction, so that one of the screw anchors 43 moves towards the seabed, and at the same time, the driven one of the first driving units 41 also rotates one of the screw anchors 43, so that the screw anchor 43 penetrates into the seabed, thereby completing the fixing operation of the offshore pile driving precision positioning auxiliary device.

[0059] It is worth mentioning that in this embodiment, each of the first driving units 41 is implemented to include a waterproof driving motor. Each of the second driving units 42 is implemented to include a waterproof telescopic device, such as a waterproof hydraulic push rod.

[0060] In another embodiment, as shown in Figure 2 、 Figure 5 and Figure 6 , each of the first driving units 41 includes a first driving member 411 and a transmission member 412, wherein each of the first driving members 411 is mounted on the device body 10 to drive one of the transmission members 412. The transmission member 412 drives at least two of the screw anchors 43 to rotate by being driven by one of the first driving members 411.

[0061] Specifically, each of the linkage arms 12 of the device body 10 is provided for mounting at least one of the first driving members 411.

[0062] Preferably, each of the transmission members 412 comprises a first transmission member 4121, at least two second transmission members 4122 and at least two third transmission members 4123. One of the first transmission members 4121 is synchronously rotatably connected to one of the first driving members 411, and one of the first transmission members 4121 is rotatably engaged with one end of one of the second transmission members 4122.

Each of the second driving units 42 is arranged to drive one of the rotating screw anchors 43 to move up and down along the axial direction of the corresponding one of the third transmission members 4123.

[0063] It is to be noted that the extending direction of each of the limiting channels 412301 is from top to bottom or from bottom to top. Each of the first driving members 411 is further provided with a waterproof housing, so that the rotatable engagement operation between the first transmission members 4121 and the second transmission members 4122 can be performed inside the waterproof housing, thereby avoiding affecting the rotatable engagement operation between the two.

[0064] It is to be further noted that each of the first driving members 411 is implemented by a driving motor with waterproof capability, each of the first transmission members 4121 is arranged as a bevel gear, each of the second transmission members 4122 is arranged as a transmission shaft with bevel gears assembled at both ends, and each of the third transmission members 4123 is arranged as a hollow pipe with a bevel gear assembled at the outer periphery. In addition, each of the screw anchors 43 has a rotatable connection relationship with the corresponding one of the second driving units 42.

[0065] Preferably, each of the second driving units 42 comprises a second driving member 421 and a driving block 422, wherein each of the second driving members 421 is mounted on the device body 10, and each of the second driving members 421 has a rotatable telescopic end for connecting with a driving block 422, and the second driving member 421 drives the corresponding driving block 422 to move in the upward or downward direction by telescoping the telescopic end. One of the driving blocks 422 is mounted in the limiting channel 412301 of one of the third transmission members 4123, and one of the driving blocks 422 is connected to the telescopic end of one of the second driving members 421, and each of the driving blocks 422 is also connected to one of the spiral anchors 43, so that when the third transmission member 4123 rotates, each of the third transmission members 4123 is arranged to drive the corresponding driving block 422 to rotate synchronously, so that the corresponding spiral anchor 43 is also driven to rotate synchronously, and when the corresponding second driving member 421 is started to telescope the telescopic end, the corresponding driving block 422 can follow the telescoping action of the telescopic end of the second driving member 421 to extend or retract the limiting channel 412301 of the corresponding third transmission member 4123.

[0066] Therefore, when the offshore pile positioning auxiliary device needs to be fixed to the seabed, each of the second driving members 421 drives the corresponding rotating driving block 422 to move towards the seabed, so that each of the spiral anchors 43 gradually penetrates into the seabed, thereby completing the fixing work.

[0074] It should be noted that the controller can control the start and stop of the suction member 31 at any time according to the sea wave signal detected by the wave detection unit. For example, when the impact force of the sea wave is large, the wave detection unit will detect and generate a large wave signal corresponding to the large wave, and transmit it to the controller. After receiving the large wave signal transmitted by the wave detection unit, the controller will control the suction member 31 to start in time, so that the suction member 31 guides a large amount of liquid into the inside of the storage unit 33 through the adapter pipe 32, thereby increasing the corresponding gravity of the entire device, so as to ensure that the screw anchors 43 in the anchoring assembly 40 can be accurately inserted towards the predetermined position on the seabed.

[0078] It is worth mentioning that the controller is provided with a remote transmission module, which is used to transmit the information transmitted by the pressure detection unit, such as the pile contact pressure, to the general control console, without the need for the operator to go to the sea to operate on site.

[0079] As a preferred, the pressure detection unit is implemented by a pressure sensor with waterproof capability.
