Description

Technical Field

[0001] This application relates to offshore cranes and pile drivers, specifically to a marine full-rotation crane and pile driver. Background Technology

[0002] Offshore piling operations typically utilize large crane vessels or floating crane platforms.

[0049] See Figure 1 As shown, a marine full-rotation crane pile driver provided according to an embodiment of this application is schematically illustrated, including a lifting device 1000 and a pile driving device 2000.

[0050] The lifting device 1000 includes a base 100, a slewing chassis 200, a slewing assembly 300, an A-frame 400, a boom 500, a winch unit 600, and a double main lifting hook 700.

[0051] The slewing chassis 200 is mounted on the base 100 via the slewing assembly 300. The winch unit 600 and the A-frame 400 are mounted on the slewing chassis 200. The bottom end of the boom 500 is hinged to the A-frame 400, and the boom 500 is connected to the corresponding winch of the winch unit 600 via a wire rope. The double main hook 700 is connected to the corresponding winch of the winch unit 600 via a wire rope passing through the top of the boom 500.

[0052] The piling device 2000 includes a pile frame 2100, a pile hammer 2200, and a fork 2300.

[0053] The pile frame 2100 includes a first pile frame section 2110, a second pile frame section 2120, and a third pile frame section 2130 connected sequentially from top to bottom.

[0054] The upper end of the first pile frame section 2110 is equipped with a hammer platform 2400. The pile hammer 2200 is connected to the corresponding winch of the winch unit 600 via a steel wire rope through the hammer platform 2400. During the pile driving process, the winch pulls the steel wire rope to control the lifting and lowering of the pile hammer 2200, and repeatedly hammers the pile body.

[0055] like Figure 2 As shown, the upper part of the first pile frame section 2110 near the boom 500 is provided with a guide rail 2111 extending along the length of the pile frame 2100. A sliding shoe 2112 is slidably connected to the guide rail 2111. The end of the sliding shoe 2112 away from the guide rail 2111 is connected to the boom 500. A main attachment point is provided in the middle of the back of the first pile frame section 2110. A swing mechanism 2500 connected to the double main hook 700 is provided at the main attachment point. A hinge shaft 2113 is provided in the lower part of the back of the first pile frame section 2110. The hinge shaft 2113 is connected to the fork 2300. The other end of the fork 2300 is connected to the A-frame 400.

[0056] Among them, the hinge shaft 2113 consists of two symmetrical hinge shafts arranged on the back of the first pile frame section 2110. The fork 2300 is a multi-segment push-pull telescopic fork that can extend and retract in coordination with the pitch of the pile frame 2100 to adjust its own length. Each fork 2300 is connected to the hinge shaft 2113. The other end of the fork 2300 is connected to the A-frame 400. The fork 2300 can be connected to the A-frame 400 through a pin.

[0057] The boom 500 supports and guides the pile frame 2100. The corresponding winch of the winch unit 600 adjusts the pitch angle of the boom 500 via wire rope, and also adjusts the double main hooks 700 via wire rope. The sliding shoe 2112 slides on the guide rail 2111, ensuring the pile frame 2100 remains vertical during pile driving, thus improving its stability and driving accuracy. A main attachment point is located at the center of the back of the first pile frame section 2110, connected to the double main hooks 700. A swing mechanism 2500 connects the two, balancing the two pulling forces exerted by the double main hooks 700 on the main attachment point during lifting and pile driving. This allows the pile frame 2100 to swing slightly within a certain range, reducing damage to the pile frame and equipment. A hinge shaft 2113 is installed on the lower back of the first pile frame section 2110. The hinge shaft 2113 is connected to the fork 2300. The fork 2300 is a multi-segment push-pull telescopic fork, which can extend and retract to adjust its length in coordination with the movement of the pile frame 2100. The other end of the fork 2300 is connected to the A-frame 400. This connection method provides additional support and stability to the pile frame 2100, making the pile driver more flexible and stable during pile driving activities, improving pile driving quality, and enhancing the pile frame's anti-overturning ability during the pile driving process.

[0058] The upper end of the third piling section 2130 is movably connected to the lower end of the second piling section 2120, and the third piling section 2130 can be folded up to the back of the second piling section 2120. In the equipment transport or non-piling operation state, folding up the third piling section reduces the overall size of the equipment, facilitating transportation and storage, while also reducing wind resistance during sea navigation and improving the stability and safety of the vessel. When piling operations are required, the third piling section 2130 is unfolded and fixed to meet the piling operation requirements.

[0059] In some embodiments, such as Figure 3 and Figure 4 As shown, the swing mechanism 2500 includes a swing seat 2510, the middle of which is hinged to the main attachment point, and both ends of the swing seat 2510 are used to be hinged one-to-one with the two main hooks of the double main hook. Hinged seats 2520 are respectively provided at both ends of the swing seat 2510. Each hinged seat 2520 is provided with a groove for cooperating with the main hook of the double main hook and a first pin. The first pin passes through the groove and is hinged to the main hook of the double main hook.

[0060] Conventional pile frames lack a correction mechanism. If the two main hooks are connected to the pile frame, the torsional torque generated by the two hooks will be directly transmitted to the pile frame structure, leading to metal fatigue, weld cracking, or even complete overturning. The swing seat 2510 is hinged to the main attachment point, forming a rotation fulcrum. Therefore, the swing seat 2510 can swing freely around the hinge fulcrum, with the swing amplitude controlled by the tension difference between the two main hooks. The swing mechanism 2500 can solve the torsional failure problem caused by the torque imbalance of the two main hooks, improving the stability and reliability of the equipment.

[0061] In some embodiments, such as Figure 5 As shown, the guide rail 2111 can be two symmetrically arranged rails, each with a sliding shoe 2112 slidably connected to it. The symmetrical rails increase connection strength, improve the pile frame's torsional resistance, protect the pile frame structure, and provide accurate guidance and positioning.

[0062] In some embodiments, such as Figure 6 As shown, the A-frame 400 can be laid down, and the A-frame 400 includes a first support 401, a second support 402 and a third support 403.

[0063] The first support 401 and the second support 402 are arranged in a V-shape vertically. The top of the first support 401 is connected to the top of the second support 402. The third support 403 is mounted on the rotating chassis 200 and is hingedly connected to the truss structure on the rotating chassis 200. The bottom of the first support 401 is hinged to the third support 403, and the bottom of the second support 402 is detachably connected to the third support 403. The top of the first support 401 and the top of the second support 402 can be hinged, and the bottom of the second support 402 and the third support 403 can be hinged. Figure 6 For reference, the connection between the bottom of the second support 402 and the third support 403 can be removed, and then the first support 401 and the second support 402 can be laid down. Therefore, the A-frame 400 has a folding function. When passing through a bridge with a navigation height restriction, the A-frame 400 can be laid down to reduce the overall height of the crane so that it can pass smoothly. After passing the bridge, the crane can be restored to normal operation or towing status as soon as possible.

[0064] In some embodiments, such as Figure 7 and Figure 8 As shown, the top of the third pile frame section 2130 is hinged to the bottom of the second pile frame section 2120. The pile frame also includes a drive mechanism 2140, which is used to drive the third pile frame section 2130 to fold onto the back of the second pile frame section 2120. The drive mechanism 2140 includes a hydraulic cylinder 2141, a first connecting rod 2142, and a second connecting rod 2143.

[0065] The hydraulic cylinder 2141 is mounted on the second pile frame section 2120 to provide power for the folding of the third pile frame section 2130. One end of the first connecting rod 2142 is hinged to the second pile frame section 2120, and the other end of the first connecting rod 2142 is hinged to one end of the second connecting rod 2143 via a second pin 2144. The other end of the second connecting rod 2143 is hinged to the third pile frame section 2130, and the telescopic end of the hydraulic cylinder 2141 is hinged to the second pin 2144.

[0066] One end of the first connecting rod 2142 can be hinged to the second pile frame section 2120 by a pin, and the other end of the second connecting rod 2143 can be hinged to the third pile frame section 2130 by a pin. The top of the third pile frame section 2130 and the bottom of the second pile frame section 2120 can be hinged by a third pin 2145. The side of the third pile frame section 2130 away from the second pile frame section 2120 from the third pin 2145 can also be detachably connected by a pin or other means.

[0067] like Figure 7As shown, when the third pile frame section 2130 is straightened, the axes of the second pile frame section 2120 and the third pile frame section 2130 coincide, the second pin 2144 is located on the side of the third pin 2145 away from the pile frame, the drive mechanism 2140 is located on the same side of the third pile frame section 2130 and the second pile frame section 2120, and the line connecting the second pin 2144 and the third pin 2145 is perpendicular to the axis of the pile frame.

[0068] like Figure 8 As shown, when the third pile frame segment 2130 folds over from its extended state onto the second pile frame segment 2120, the connection point between the third pile frame segment 2130 and the second pile frame segment 2120 on the side away from the third pin 2145 is disengaged. The hydraulic cylinder 2141 pulls the second pin 2144, which in turn pulls the first connecting rod 2142 and the second connecting rod 2143 to fold the third pile frame segment 2130. During the folding process, the third pile frame segment 2130 rotates around the third pin 2145 until it folds over to the back of the second pile frame segment 2120. At this time, the line connecting the second pin 2144 and the third pin 2145 is parallel to the axis of the second pile frame segment 2120 and the third pile frame segment 2130.

[0069] In some embodiments, a machine room and an electrical room are provided on the slewing chassis, and the winch unit 600 is located in the machine room.

[0070] The winch unit 600 includes a main hook winch, a luffing winch, a hammer winch, and a hammer-starting winch. The luffing winch is connected to the top of the boom 500 via a wire rope passing through the top of the A-frame 400, thereby driving the boom 500 to luff and adjust its pitch angle. The main hook winch is connected to the double main hooks 700 via a wire rope passing through the top of the boom 500, thereby driving the double main hooks 700 to raise and lower.

[0071] The electrical room contains transformers, frequency converters, and electrical control equipment.

[0072] In some embodiments, the winch unit 600 further includes a piling main hook winch and a piling auxiliary hook winch, and the piling device further includes a piling main hook and a piling auxiliary hook. The piling main hook winch is connected to the piling main hook via a wire rope, and the piling auxiliary hook winch is connected to the piling auxiliary hook via a wire rope.

[0073] like Figure 9 A pile-lifting platform is installed at the upper end of the first pile frame section 2110 shown. The main pile-driving hook winch is connected to the main pile-driving hook via a steel wire rope through the pile-lifting platform, and the auxiliary pile-driving hook winch is connected to the auxiliary pile-driving hook via a steel wire rope through the pile-lifting platform. The pile-lifting platform and the hammer platform 2400 are connected to form a comprehensive platform.

[0074] In some embodiments, there are two main pile hooks and two auxiliary pile hooks, which are arranged symmetrically along the axis of the pile frame.

[0075] In some embodiments, the hammer platform 2400 is provided with a hammer pulley block and a hammer-starting pulley block, and the hammer winch is connected to the pile hammer 2200 via a wire rope wound around the hammer pulley block. The hammer-starting winch is connected to the pile hammer 2200 via a wire rope wound around the hammer-starting pulley block.

[0076] The 2200 piling hammer can be a hydraulic hammer, which is equipped with a water cooling system.

[0077] In some embodiments, lifting rails are provided on the left and right sides of the pile frame, and lifting platforms are provided on the lifting rails. An opening and closing multi-stroke pile gripper is provided at the front of the second pile frame section 2120.
