The pile driving vessel mainly includes a hull, a pile driving frame and a pile driving hammer. The hull is used for bearing, and during pile driving operation, the hull needs to be fixed around the target pile driving position so that the target pile driving position is located within the operation range of the pile driving vessel. The pile driving frame is used for lifting or lowering a precast pile, and the pile driving hammer is used for gradually driving the precast pile into the seabed by impact force until the designed depth.

[0003] During group pile operation, precast piles need to be arranged at multiple positions in a certain area.

After completing the pile driving operation at one position, the position of the whole pile driving vessel needs to be adjusted so that the next pile driving position is located within the operation range of the pile driving vessel. When using the pile driving vessel in the prior art to perform group pile operation, the position of the whole pile driving vessel needs to be adjusted multiple times, the frequency of moving the vessel is high, and the group pile operation efficiency is affected.

DETAILED DESCRIPTION

[0051] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0052] The following is combined Figures 1 to 11 The piling vessel of the present invention is described.

[0053] like Figures 1 to 11 As shown, the piling vessel provided in this embodiment of the invention includes a mother ship, a piling vessel body, and a first drive device.

[0054] Specifically, the mother ship includes a mother ship hull 1, a power system, and a fixing system. The mother ship hull 1 can float on the water surface, the power system is used to drive the mother ship hull 1 to move on the water surface, and the fixing system is used to fix the mother ship hull to the target position.

[0055] The piling vessel includes a sub-hull 2, a piling frame 3, and a piling hammer. The piling frame 3 is located on the sub-hull 2 ​​and is used to lift or lower precast piles. The piling hammer is located on the piling frame 3 and is used to apply impact force to the precast piles so that they gradually penetrate deeper into the water.

[0056] The sub-hull 2 ​​is reciprocally slidably mounted on the mother hull 1, and the sliding direction of the sub-hull 2 ​​relative to the mother hull 1 is along the longitudinal direction of the mother hull 1. A first driving device is disposed between the mother hull 1 and the sub-hull 2, and the first driving device is used to drive the sub-hull 2 ​​to slide reciprocally relative to the mother hull 1. By driving the sub-hull 2 ​​to slide, the relative position of the sub-hull 2 ​​and the mother hull 1 can be adjusted along the longitudinal direction of the mother hull 1.

[0057] In this way, the pile driving boat body is slidably connected with the mother ship body 1, and before pile driving starts, the position of the mother ship body 1 is adjusted according to the pile group operation area and the mother ship body 1 is fixed. According to a pile driving position to be driven in the pile group operation area, the relative position of the pile driving boat body and the mother ship body 1 is adjusted so that the pile driving position to be driven is located in the operation range of the pile driving boat body. After the pile driving operation at the position is completed, the relative position of the pile driving boat body and the mother ship body 1 is adjusted according to another pile driving position to be driven in the pile group operation area so that the pile driving position to be driven is located in the operation range of the pile driving boat body. In this way, the pile driving operation can be completed for each pile driving position to be driven in the pile group operation area. When the position of the pile driving boat body is adjusted, the position of the mother ship body 1 is fixed, and the mother ship body 1 serves as a position adjustment reference for the pile driving boat body, which facilitates the position adjustment of the pile driving boat body, reduces the difficulty of the position adjustment of the pile driving boat body, reduces the frequency of moving the pile driving boat, improves the position accuracy of the pile driving boat body, improves the efficiency and accuracy of the pile group operation, and solves the problems of high frequency of moving the pile driving boat, low efficiency of the pile group operation, and difficulty in ensuring the accuracy of the pile group operation in the prior art.

[0058] In the embodiment of the present application, the first driving device comprises a first winding drum 4, a second winding drum 5, a first driving member, a second driving member and a traction rope 6.

[0059] The first winding drum 4 and the second winding drum 5 are arranged in pairs, and each pair of the first winding drum 4 and the second winding drum 5 is distributed at both ends of the mother ship body 1 in the longitudinal direction of the mother ship body 1. The rotation axis of the first winding drum 4 and the rotation axis of the second winding drum 5 are both perpendicular to the longitudinal direction of the mother ship body 1.

[0060] Each pair of the first winding drum 4 and the second winding drum 5 corresponds to a traction rope 6, one end of the traction rope 6 is wound around the first winding drum 4, the other end of the traction rope 6 is wound around the second winding drum 5, and the traction rope 6 is connected with the child ship body 2.

[0061] The first driving member is used to drive the first winding drum 4 to rotate reciprocally, and the second driving member is used to drive the second winding drum 5 to rotate reciprocally. The first driving member and the second driving member can be, but are not limited to, an electric motor or a hydraulic motor.

[0062] When the first driving member drives the first winding drum 4 to wind up the traction rope 6, the second driving member needs to drive the second winding drum 5 to release the traction rope 6, so that the child ship body 2 moves in the direction close to the first winding drum 4. When the first driving member drives the first winding drum 4 to release the traction rope 6, the second driving member needs to drive the second winding drum 5 to wind up the traction rope 6, so that the child ship body 2 moves in the direction close to the second winding drum 5.

[0063] It should be noted that the part of the traction rope 6 between the first reel 4 and the second reel 5 is in a tension state, and one of the first reel 4 and the second reel 5 releases the traction rope 6 at a speed consistent with the winding speed of the traction rope 6 by the other one of the first reel 4 and the second reel 5, so that the traction rope 6 remains in a tension state and can bear the gravity of the piling boat body, thereby ensuring the stability of the piling boat body.

[0064] The first reel 4 and the second reel 5 are each provided with at least two first reels 4 and second reels 5, and each first reel 4 and each second reel 5 are spaced apart along a direction perpendicular to the longitudinal direction of the mother ship body 1. Each pair of first reel 4 and second reel 5 corresponds to one traction rope 6, and each traction rope 6 is connected to the child ship body 2.

[0065] In this way, the movement of the child ship body 2 is supported by at least two traction ropes 6, which can provide a supporting force and a traction force, thereby improving the stability of the piling boat body and reducing the requirement for the bearing capacity of each traction rope 6.

[0066] In the embodiment, the child ship body 2 is provided with a clamping mechanism 7, which can be switched between a clamping state and a release state. When the clamping mechanism 7 is switched to the clamping state, the child ship body 2 and the clamping mechanism 7 are relatively fixed with the traction rope 6, and at this time, the traction rope 6 can drive the piling boat body to displace. When the clamping mechanism 7 is switched to the release state, the child ship body 2 can be separated from the traction rope 6, and at this time, the piling boat body can be stored alone, for example, after the piling operation is completed, the piling boat body can be stored above the mother ship body 1.

[0067] In specific embodiments, the clamping mechanism 7 includes a third driving member 9 and a pair of clamping jaws 8.

[0068] The pair of clamping jaws 8 are arranged on the child ship body 2, one end of the clamping jaw 8 is rotatably connected to the child ship body 2, and the rotation direction of the clamping jaw 8 relative to the child ship body 2 is parallel to the longitudinal direction of the mother ship body 1. Each clamping jaw 8 corresponds to one third driving member 9, and the third driving member 9 is arranged between the clamping jaw 8 and the mother ship body 1, and the third driving member 9 can drive the clamping jaw 8 to reciprocate relative to the mother ship body 1.

[0069] When the clamping jaw 8 is rotated to a spacing between the ends of the pair of clamping jaws 8 away from the mother ship body 1, an opening is formed between the ends of the pair of clamping jaws 8 away from the mother ship body 1, corresponding to the release state of the clamping mechanism 7. At this time, the traction rope 6 can pass through the opening to enter or exit the space between the pair of clamping jaws 8.

[0070] When the clamping jaw 8 is rotated to abut against each other at the ends of the pair of clamping jaws 8 away from the mother ship body 1, it corresponds to the clamping state of the clamping mechanism 7. At this time, the traction rope 6 cannot enter or exit the space between the pair of clamping jaws 8.

[0071] The third driving member 9 can be, but is not limited to, a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0072] In the embodiment, the pile driving barge further comprises a turnover frame 10 and a second driving device 11.

[0073] The turnover frame 10 is arranged on the mother hull 1, and the turnover frame 10 is rotationally connected to the mother hull 1. The rotation axis of the turnover frame 10 is arranged along the longitudinal direction of the mother hull 1. The turnover frame 10 can be switched between a storage position and a working position. The second driving device 11 is used to drive the turnover frame 10 to rotate between the storage position and the working position.

[0074] The second driving device 11 can be, but is not limited to, an electric motor or a hydraulic motor.

[0075] When the turnover frame 10 rotates to the storage position, the turnover frame 10 is located above the mother hull 1. A support member 26 can be arranged on the mother hull 1 to support the turnover frame 10.

[0076] When the turnover frame 10 rotates to the working position, the turnover frame 10 is located beside the mother hull 1.

[0077] The first driving device is arranged on the turnover frame 10. When the turnover frame 10 is in the working position, the first driving device is located below the turnover frame 10.

[0078] In some embodiments, when the turnover frame 10 is in the working position, the lower end of the turnover frame 10 is provided with a clearance space for avoiding the pile driving barge body. Alternatively, in other embodiments, the turnover frame 10 comprises a pair of support frames 28. The support frames 28 are arranged at both ends of the mother hull 1 along the longitudinal direction of the mother hull 1. Each support frame 28 is rotationally connected to the mother hull 1, and the rotation axis of the support frame 28 is parallel to the longitudinal direction of the mother hull 1. The second driving device 11 comprises a pair of fifth driving members. Each support frame 28 corresponds to a fifth driving member. The fifth driving member can drive the support frame 28 to rotate relative to the mother hull 1.

[0079] A limiting structure 12 is arranged on the turnover frame 10. The limiting structure 12 is arranged on the rope outlet side of each first winding drum 4. The limiting structure 12 is used to limit the displacement component of the traction rope 6 in a direction perpendicular to the longitudinal direction of the mother hull 1.

[0080] Specifically, the limiting structure 12 comprises a plurality of rollers capable of rotating around axes, the axes of the plurality of rollers enclosing a closed loop, a plane of the closed loop being perpendicular to the longitudinal direction of the mother hull 1, and the traction rope 6 being arranged in the closed loop. The rollers are capable of limiting the position of the traction rope 6, and when the traction rope 6 moves, the rollers are capable of rolling under the friction between the rollers and the traction rope 6 when the traction rope 6 contacts the rollers. The friction between the traction rope 6 and the rollers is rolling friction, which can reduce the wear of the traction rope 6 and prolong the service life of the traction rope 6 and the piling boat.

[0081] In further embodiments, the piling boat further comprises a rotating frame 13 and a lifting device 14, and the rotating frame 13 and the lifting device 14 are both arranged on the turnover frame 10.

[0082] When the turnover frame 10 rotates to the working position, the rotating frame 13 and the lifting device 14 are both located at the upper end of the turnover frame 10.

[0083] The rotating frame 13 is rotationally connected to the turnover frame 10, and the rotation axis of the rotating frame 13 relative to the turnover frame 10 is parallel to the rotation axis of the turnover frame 10 relative to the mother hull 1. When the turnover frame 10 rotates relative to the mother hull 1, the rotating frame 13 will rotate relative to the turnover frame 10 under the action of its own gravity. When the turnover frame 10 rotates to the storage position, the rotating frame 13 rotates relative to the turnover frame 10 so that the gravity center of the rotating frame 13 is located below the rotation axis of the rotating frame 13 relative to the turnover frame 10.

[0084] The lifting end of the lifting device 14 is provided with a connecting piece 15, and the connecting piece 15 is capable of detachably connecting with the child hull 2 and the rotating frame 13. At least the lifting end of the lifting device 14 is capable of rotating relative to the turnover frame 10 around an axis parallel to the longitudinal direction of the mother hull 1.

[0085] In this way, when the connecting piece 15 is connected with the child hull 2, the child hull 2 can be lifted synchronously with the lifting end of the lifting device 14. When the connecting piece 15 is connected with both the rotating frame 13 and the child hull 2, the child hull 2 is relatively fixed with the rotating frame 13. At this time, when the turnover frame 10 is driven to rotate relative to the mother hull 1, the rotating frame 13 and the child hull 2 will synchronously rotate relative to the turnover frame 10 around the rotation axis of the rotating frame 13 relative to the turnover frame 10, and the gravity center of the piling boat body and the rotating frame 13 as a whole is located below the rotation axis of the rotating frame 13 relative to the turnover frame 10. During the rotation of the turnover frame 10 relative to the mother hull 1, the piling boat body is always in an upright state, avoiding the overall overturning of the piling boat body.

[0086] In specific embodiments, the lifting device 14 comprises a winch, and the end of the wire rope of the winch serves as the lifting end.

[0087] In the embodiments of the present application, the connecting piece 15 comprises a pin body 16, a clamping portion 17, and a fourth driving member.

[0088] The first end of the pin body 16 is connected with the lifting end of the lifting device 14, and a first pin hole is arranged on the rotating frame 13 and a second pin hole is arranged on the sub-hull 2. The first end of the pin body 16 can extend into the first pin hole, and the second end of the pin body 16 can extend into the second pin hole.

[0089] The clamping portions 17 are arranged in two groups, and the two groups of clamping portions 17 are spaced apart along the axial direction of the pin body 16. Each group of clamping portions 17 includes at least two clamping portions 17, and each clamping portion 17 in each group is spaced apart along the circumferential direction of the pin body 16.

[0090] The side wall of the pin body 16 is provided with a mounting groove, and the clamping portion 17 is arranged in the mounting groove. The clamping portion 17 is rotationally connected with the pin body 16, and the clamping portion 17 can be switched between the clamping position and the avoiding position. Each clamping portion 17 corresponds to a fourth driving member, and the fourth driving member is used to drive the clamping portion 17 to switch between the clamping position and the avoiding position.

[0091] The side wall of the first pin hole is provided with a first clamping groove, and the side wall of the second pin hole is provided with a second clamping groove.

[0092] When the clamping portion 17 rotates to the clamping position, the clamping portion 17 protrudes from the side wall of the pin body 16. When the first end of the pin body 16 is located in the first pin hole, the clamping portion 17 corresponding to the first end of the pin body 16 is located in the first clamping groove, and at this time, the connecting piece 15 is relatively fixed with the rotating frame 13. When the second end of the pin body 16 is located in the first pin hole, the clamping portion 17 corresponding to the second end of the pin body 16 is located in the second clamping groove, and at this time, the connecting piece 15 is relatively fixed with the sub-hull 2.

[0093] When the clamping portion 17 rotates to the avoiding position, the clamping portion 17 is completely located in the mounting groove, and at this time, the pin body 16 can freely enter and exit the first pin hole and the second pin hole, the connecting piece 15 can be disconnected with the rotating frame 13, and the connecting piece 15 can also be disconnected with the sub-hull 2.

[0094] In the embodiment, the rotating frame 13 is arranged as a rigid frame, and when the turnover frame 10 rotates relative to the mother hull 1, the shaking of the rotating frame 13 and the piling boat body can be reduced.

[0095] Specifically, the rotating frame 13 includes a first support 18 and a second support 19.

[0096] The first support 18 is arranged in a pair, the pair of first supports 18 are parallel to each other, and the pair of first supports 18 are spaced apart along the longitudinal direction of the mother hull 1. The first end of the first support 18 is rotationally connected with the turnover frame 10, and the rotating axis of the first support 18 relative to the turnover frame 10 is parallel to the longitudinal direction of the mother hull 1.

[0097] The second end of the second support 19 is connected to the second end of the pair of first supports 18, and the first pin hole is arranged in the second support 19, and the pin body 16 can only enter and exit the first pin hole from the side of the second support 19 away from the first support 18.

[0098] In the embodiment of the application, the piling barge body further comprises a first water tank 20, a second water tank 21, a first water pump 24 and a second water pump 25.

[0099] In the working position of the turnover frame 10, the distribution directions of the first water tank 20 and the second water tank 21 are perpendicular to the longitudinal direction of the mother ship body 1, and the position to be piled is located on the side of the piling barge body away from the mother ship body 1.

[0100] The first water tank 20 and the second water tank 21 are connected by a first water pipe 22 and a second water pipe 23, the two ends of the first water pipe 22 are respectively connected to the first water tank 20 and the second water tank 21, and the two ends of the second water pipe 23 are respectively connected to the first water tank 20 and the second water tank 21.

[0101] The first water pump 24 is arranged in the first water pipe 22, and is used to transport water in the first water tank 20 to the second water tank 21. The second water pump 25 is arranged in the second water pipe 23, and is used to transport water in the second water tank 21 to the first water tank 20.

[0102] Specifically, a first control valve can be arranged on the first water pipe 22, and a second control valve can be arranged on the second water pipe 23. The first control valve is used to control the on-off state of the first water pipe 22, and the second control valve is used to control the on-off state of the second water pipe 23. When the first water pump 24 and the second water pump 25 are controlled to start or stop, the states of the first control valve and the second control valve need to be controlled.

[0103] For convenience of description, it is defined that, in the working position of the turnover frame 10, the distance between the first water tank 20 and the mother ship body 1 is less than the distance between the second water tank 21 and the mother ship body 1, and the first water tank 20 is closer to the mother ship body 1 than the second water tank 21. When the piling barge body hoists the prefabricated pile, the prefabricated pile has a downward force on the piling frame 3 of the piling barge body, in order to avoid overturning of the piling barge body, water in the second water tank 21 needs to flow to the first water tank 20, so that the center of gravity of the piling barge body moves along the direction close to the mother ship body 1, to balance the center of gravity of the whole of the piling barge body and the prefabricated pile. After the prefabricated pile contacts the water bottom, as the downward force of the prefabricated pile on the piling barge body decreases, water in the first water tank 20 needs to gradually flow to the second water tank 21 according to the size of the force of the prefabricated pile on the piling barge body.

[0104] It should be pointed out finally that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the same; and although the present application has been described in detail with reference to the foregoing embodiments, it should be appreciated by those skilled in the art that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features thereof can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
