Description

Technical Field

[0001] The present application relates to the technical field of ships, and in particular to a river dredging ship. Background Art

[0002] A dredging ship, also known as a dredger, is used to clean and excavate the silt accumulated in the river channel to dredge the river channel for ships to pass through. According to the different ways in which the dredging ship cleans the silt, the dredging ship can be divided into types such as a cutter suction dredger and a trailing suction dredger. For a cutter suction dredger, the silt deposited on the riverbed is usually stirred into muddy water by a dredging device, and then the muddy water is sucked to a designated location for temporary storage or further treatment. During the dredging operation, the hull of the dredging ship needs to remain stable in the river channel to facilitate the stirring and suction of the dredging device. In the prior art, the hull is usually fixed with the help of the positioning piles of the dredging ship. When operating, the positioning piles pass through the hull from top to bottom and are inserted into the riverbed; when not operating, the positioning piles are stored on the hull through a storage device. However, in the prior art, due to their relatively large weight and volume, it is difficult to stably and effectively control the positioning piles during the retraction and release process.

DETAILED DESCRIPTION

[0028] The following combination Figure 1-Figure 4 This application is described in further detail.

[0029] An embodiment of the present application provides a river dredging vessel, such as Figures 1 to 4 As shown, the river dredging vessel includes:

[0030] Hull 100;

[0031] A dredging device 200, which is disposed on the hull 100 and is used to stir and suck the sludge;

[0032] A rotating frame 300, which is rotatably disposed on the hull 100, and two rotating frames symmetrically disposed along the width direction of the hull 100;

[0033] A rotation driving device 400, which corresponds to the rotating frame 300 one by one and is disposed on the hull 100, the rotation driving device 400 is connected to the rotating frame 300, and drives the rotating frame 300 to rotate;

[0034] The positioning pile 500 corresponds to the rotating frame 300 one by one and is arranged on the rotating frame 300. The rotating frame 300 is provided with a locking device 600 for locking the positioning pile 500;

[0035] A first hoisting device 700, which corresponds to the positioning pile 500 one by one, is arranged on the hull 100 and includes a first traction rope 710, which is connected to one end of the top of the positioning pile 500, and the first traction rope 710, the part of the positioning pile 500 exposed from the hull 100 and the hull 100 form a triangle relationship;

[0036] When the positioning pile 500 is lowered, the rotation drive device 400 drives the rotating frame 300 to rotate, so that the positioning pile 500 rotates from horizontal to inclined, the locking device 600 releases the positioning pile 500, the first traction rope 710 stretches and supports the positioning pile 500, and the positioning pile 500 slides downwardly relative to the locking device 600; when the middle part of the positioning pile 500 slides to the locking device 600, the locking device 600 locks and fixes the positioning pile 500, and the rotation drive device 400 drives the rotating frame 300 to continue to rotate, so that the positioning pile 500 rotates from inclined to vertical, the first traction rope 710 continues to stretch and support the positioning pile 500; when the positioning pile 500 rotates to vertical, the locking device 600 releases the positioning pile 500 again, the first traction rope 710 shortens and supports the positioning pile 500, and the positioning pile 500 slides downward relative to the locking device 600;

[0037] When the positioning pile 500 is stored, the locking device 600 locks and fixes the positioning device, and the rotating drive device 400 drives the rotating frame 300 to rotate, so that the positioning pile 500 rotates from vertical to horizontal, and the first traction rope 710 is shortened and the positioning pile 500 is supported; when the positioning pile 500 is rotated to the horizontal, the locking device 600 releases the positioning pile 500, and the first traction rope 710 continues to shorten and drag the positioning pile 500, and the positioning pile 500 slides horizontally relative to the locking device 600; when the bottom of the positioning pile 500 slides to the locking device 600, the locking device 600 locks and fixes the positioning pile 500.

[0038] like Figure 1 As shown, in this embodiment, the hull 100 can be provided with a deck for the convenience of arranging other devices and passenger cabins. The dredging device 200 is a functional device of a river dredging ship, which is used to stir and suck the silt to achieve the cleaning and excavation of the silt. The positioning piles 500 are used to fix the hull 100 in the river channel. The positioning piles 500 can be set to two and distributed on both sides of the width direction of the hull 100 to keep the hull 100 stable. When in use, the positioning piles 500 are vertically penetrated on the hull 100 and inserted into the river bottom; when not in use, the positioning piles 500 can be horizontally stored on the hull 100 along the length direction of the hull 100 to facilitate the normal navigation of the hull 100.

[0039] The positioning piles 500 in this embodiment are connected to the hull 100 through the rotating frame 300; specifically, the rotating frame 300 is rotatably connected to the hull 100 relative to the horizontal plane, and the positioning piles 500 are arranged on the rotating frame 300 in a one-to-one correspondence. When the rotating frame 300 rotates, it can drive the positioning piles 500 to rotate synchronously. It is not difficult to understand that the rotation range of the positioning piles 500 should be between the two positions when it is in use and when it is not in use, that is, between the horizontal and vertical positions in this embodiment, that is, 90 degrees. Of course, in some embodiments, the rotation range of the positioning piles 500 can also be larger than 90 degrees. The rotation of the rotating frame 300 is driven by the rotation drive device 400, and the rotation drive device 400 corresponds to the rotating frame 300 one by one to control the two positioning piles 500 respectively. The rotating frame 300 is also provided with a locking device 600, which is used to lock and fix the positioning pile 500 on the rotating frame 300 or release the positioning pile 500 on the rotating frame 300. The locking device 600 may be a hydraulic clamping type locking device 600, which may include a locking block driven by hydraulic oil, and the locking block may clamp and fix the positioning pile 500 or release the clamped positioning pile 500. During the rotation of the rotating frame 300, the locking device needs to lock and fix the positioning pile 500 to prevent the positioning pile 500 from sliding freely under the action of its own weight when the positioning pile 500 is rotated to tilt; and when the rotating frame 300 is rotated to the right position, the locking device needs to release the positioning pile 500 to facilitate the lowering of the positioning pile 500.

[0040] like Figure 1 As shown, in this embodiment, a first hoisting device 700 is also provided on the hull 100, and the first hoisting device 700 is used to pull or drag the positioning pile 500. It corresponds to the positioning pile 500 one by one, and specifically includes a first traction rope 710. The first traction rope 710 is preferably a steel wire rope to have a higher bearing capacity and strength. The first traction rope 710 can be fixed to the top of the positioning pile 500 by a lock and other components, and the traction of the positioning pile 500 can be achieved by retracting and releasing the first traction rope 710. When the first traction rope 710 plays its traction role, the first traction rope 710, the part of the positioning pile 500 exposed from the hull 100 and the hull 100 form a triangular relationship.

[0041] Specifically, when the dredging device 200 performs dredging operations, the positioning pile 500 needs to be lowered vertically into the riverbed. This process may include four stages, such as Figure 2 and Figure 3As shown, the first stage is: the rotation drive device 400 drives the rotating frame 300 to rotate, so that the positioning pile 500 rotates from horizontal to tilted. During the rotation of the rotating frame 300, the first traction rope 710 extends, and the locking device 600 locks and fixes the positioning pile 500. It is not difficult to see that since the first traction rope 710 applies traction to the positioning pile 500, it can enhance the locking effect of the locking device 600 on the positioning pile 500, so as to further prevent the positioning pile 500 from moving easily during the rotation of the rotating frame 300.

[0042] like Figure 3 As shown, the second stage is: when the positioning pile 500 rotates to tilt, the locking device 600 releases the positioning pile 500. The tilt angle of the positioning pile 500 can be reasonably selected according to actual needs; but it is not difficult to see that the tilted positioning pile 500 will slide downward relative to the locking device 600 under the action of its own weight; at the same time, the larger the tilt angle of the positioning pile 500, the faster the downward sliding speed. During the sliding process of the positioning pile 500, the first traction rope 710 is further extended and always supports the positioning pile 500. At this time, due to the supporting force applied by the traction rope, the positioning pile 500 is buffered during the sliding process, and the lowering process is also more stable.

[0043] like Figure 3 and Figure 4 As shown, the third stage is: when the middle of the positioning pile 500 slides to the locking device 600, the locking device 600 locks and fixes the positioning pile 500. In this process, due to the traction of the first traction rope 710, the instantaneous impact on the locking device 600 when locking and fixing the positioning pile 500 is relatively small, so the positioning pile 500 is not easy to be difficult to lock due to inertia during the locking process. Subsequently, the rotation drive device 400 drives the rotating frame 300 to continue to rotate, so that the positioning pile 500 rotates from tilted to vertical, and the first traction rope 710 continues to extend and stretches the positioning pile 500.

[0044] like Figure 4 As shown, the fourth stage is: when the positioning pile 500 rotates to vertical, the locking device 600 releases the positioning pile 500 again. At this time, the vertical positioning pile 500 slides vertically downward relative to the locking device 600 under the action of its own weight to be inserted into the riverbed. In this process, the first traction rope 710 is shortened and the positioning pile 500 is supported. It is not difficult to see that the speed at which the first traction rope 710 is shortened should be greater than the speed at which the positioning pile 500 slides, otherwise it is difficult to support the positioning pile 500. When the first traction rope 710 has a supporting effect on the positioning pile 500, it can make the subsequent lowering process of the positioning pile 500 smoother.

[0045] Likewise, when the dredging operation is completed, the positioning piles 500 need to be stored horizontally on the hull 100. This process may include two stages, such as Figure 4 As shown, the first stage is: the locking device 600 locks and fixes the positioning device, and the rotating drive device 400 drives the rotating frame 300 to rotate, so that the bottom of the positioning pile 500 rotates and slides out from the mud at the bottom of the river to separate from the river bottom, so that the positioning pile 500 can be rotated from vertical to horizontal. In this process, the first traction rope 710 is shortened and the positioning pile 500 is supported. It is not difficult to see that when the positioning pile 500 is lowered to the river bottom, its center of gravity is close to the river bottom. It is usually difficult to overcome the resistance encountered by the positioning pile 500 when rotating by relying solely on the driving force applied by the rotating drive device 400; and by the first traction rope 710 pulling the positioning pile 500 at the top of the positioning pile 500, it is easier to overcome the resistance encountered by the positioning pile 500 when rotating and make the positioning pile 500 rotate smoothly. At the same time, during the rotation of the positioning pile 500, by controlling the shortening speed of the first traction rope 710, the rotation process of the positioning pile 500 can be made more stable.

[0046] like Figure 2 As shown, the second stage is: when the positioning pile 500 rotates to the horizontal, the locking device 600 releases the positioning pile 500, the first traction rope 710 continues to shorten and drags the positioning pile 500, and under the traction of the first traction rope 710, the positioning pile 500 slides horizontally relative to the locking device 600, so that the positioning pile 500 can be arranged on the hull 100. When the bottom of the positioning pile 500 slides to the locking device 600, the locking device 600 locks and fixes the positioning pile 500 to prevent the positioning pile 500 from moving when stored.

[0047] In summary, the present application sets up a rotating frame 300, arranges the positioning pile 500 on the rotating frame 300 through the locking device 600, drives the rotating frame 300 to rotate through the rotating driving device 400, and pulls the positioning pile 500 through the first traction rope 710 of the first traction device, so that the positioning pile 500 can be retracted and released more smoothly during the process of retracting and releasing the positioning pile 500, thereby improving the problem that the positioning pile 500 is difficult to control during the process of retracting and releasing.

[0048] Specifically, the river dredging vessel further includes a slide rail 800 , which is disposed on the hull 100 and corresponds one-to-one with the positioning piles 500 ; when the positioning piles 500 are rotated to a horizontal position, they overlap with the slide rail 800 and are slidably disposed on the slide rail 800 .

[0049] like Figure 1 and Figure 2As shown, in this embodiment, the positioning pile 500 can be set as a rotating body, and one end of its bottom can be set as a cone to facilitate insertion into the riverbed. The slide rail 800 can extend along the length direction of the hull 100, and the two slide rails 800 can be arranged on both sides of the width direction of the hull 100. The top side of the slide rail 800 can be set as an arc, and its inner diameter is adapted to the outer diameter of the positioning pile 500, so that the slide rail 800 can effectively position the positioning pile 500. When the dredging operation is completed and the positioning pile 500 is rotated to a horizontal level, the top end of the positioning pile 500 is at least vertically projected downward within the range corresponding to the slide rail 800, and overlaps with the slide rail 800. At this time, the slide rail 800 can limit the rotation of the positioning pile 500 to prevent the positioning pile 500 from rotating excessively and causing a collision with the hull 100 or causing an impact on the rotation drive device 400. Then, when the first traction rope 710 is shortened to drag the positioning pile 500 horizontally, the positioning pile 500 slides on the slide rail 800 to be stored on the hull 100. When dredging is required and the positioning pile 500 is rotated from horizontal to tilted, the top end of the positioning pile 500 will not tilt downward due to the existence of the slide rail 800, making it difficult to drive the positioning pile 500.

[0050] It is understandable that, in this embodiment, by providing the slide rail 800 , the slide rail 800 can guide the sliding of the positioning pile 500 when the positioning pile 500 is stored on the hull 100 , thereby further improving the smooth control of the positioning pile 500 during the storage and deployment process.

[0051] Specifically, the first winch device 700 also includes a first roller 720 and a first winch drive device. The end of the first traction rope 710 away from the positioning pile 500 is connected to the first roller 720, and the first roller 720 is connected to the first winch drive device. The first winch drive device drives the first roller 720 to rotate so that the first traction rope 710 is extended or shortened.

[0052] like Figure 1 and Figure 2 As shown, in this embodiment, the first hoisting drive device can be a motor, an internal combustion engine, etc., which has a rotating output end. The output end of the first hoisting drive device can be driven by the roller of the first roller 720, and it can be specifically driven by a gear box to improve its driving ability for the first roller 720. The end of the first traction rope 710 away from the positioning pile 500 can be fixed on the side of the first roller 720. When the first hoisting device 700 drives the first roller 720 to rotate, the first roller 720 can realize the automatic retraction and release of the first traction rope 710 to achieve the purpose of properly traction of the positioning pile 500.

[0053] It can be understood that this embodiment, by providing the first winch device 700 and the first roller 720, can realize the automatic retraction and release of the first traction rope 710 and the control of the retraction and release speed, so that the first traction rope 710 can achieve auxiliary control of the positioning pile 500, thereby making the retraction and release process of the positioning pile 500 smoother.

[0054] Specifically, the rotation driving device 400 is a hydraulic telescopic device, one end of the rotation driving device 400 is rotatably connected to the rotating frame 300 , and the other end of the rotation driving device 400 is rotatably connected to the hull 100 .

[0055] like Figures 1 to 4 As shown, in this embodiment, it is exemplarily explained that the rotation drive device 400 can be set as a hydraulic telescopic device, which can include an inner rod and a sleeve rod, and the inner rod can slide in the sleeve rod under the drive of hydraulic oil to achieve telescopic. One end of the rotation drive device 400 can be rotatably connected to the rotating frame 300 through a bracket, and the other end can be rotatably connected to the hull 100 through a bracket; this embodiment takes the inner rod connected to the rotating frame 300 and the sleeve rod connected to the hull 100 as an example. When connected, the end of the sleeve rod close to the inner rod can be set on the bracket, and the end of the sleeve rod away from the inner rod extends to below the deck of the hull 100, and is rotatably set in the hull 100, so that the telescopic length of the rotation drive device 400 can meet the rotation range requirements of the rotating frame 300. It is not difficult to see that when the rotation driving device 400 is extended, it can drive the rotating frame 300 to rotate forward, so that the positioning pile 500 can be rotated from horizontal to vertical; when the rotation driving device 400 is shortened, it can drive the rotating frame 300 to rotate reversely, so that the positioning pile 500 can be rotated from vertical to horizontal.

[0056] It is understandable that in this embodiment, by configuring the rotation drive device 400 as a hydraulic telescopic device, the drive device can drive the rotating frame 300 relatively smoothly, so that the rotating frame 300 can drive the positioning pile 500 to rotate synchronously, so as to achieve smooth retraction and extension of the positioning pile 500.

[0057] Specifically, the river dredging vessel also includes a rotating arm 900, which connects the rotating frame 300 and the hull 100, and is rotatably disposed on the hull 100. The rotating arms 900 are arranged in groups of two and correspond one-to-one to the positioning piles 500. The two rotating arms 900 arranged in groups are distributed on both sides of the positioning piles 500.

[0058] like Figure 1 and Figure 2As shown, in this embodiment, the rotating arm 900 can be used to connect the rotating frame 300 with the hull 100, so that the rotating frame 300 can be rotatably arranged on the hull 100. The rotating arm 900 and the positioning pile 500 are staggered to avoid interference between the positioning pile 500 and the rotating arm 900 when the positioning pile 500 rotates. The rotating arms 900 can be arranged on both sides of any positioning pile 500, that is, the rotating arms 900 are arranged in groups of two, and the two rotating arms 900 arranged in groups are distributed on both sides of the same positioning pile 500. The shape of the longitudinal section of the rotating arm 900 can be reasonably set according to actual needs. In this embodiment, a shape similar to a triangle is taken as an example. The inner rod of the rotating drive device 400 can be rotatably connected to the top of the rotating arm 900. When the rotating drive device 400 is extended or retracted, it can drive the rotating frame 300 at intervals through the rotating arm 900.

[0059] It can be understood that, in this embodiment, by providing the rotating arm 900, it can not only enable the rotating frame 300 to synchronously drive the positioning pile 500 to rotate between vertical and horizontal when rotating, but also form a stable and effective support for the rotating frame 300 during the rotation process, so that the rotation of the rotating frame 300 and the positioning pile 500 is smoother.

[0060] Specifically, the dredging device 200 includes a hanger 210, a second hoisting device 220, a fixed frame 230, a reamer device 240 and a suction device 250. The reamer device 240 and the suction device 250 are both arranged on the fixed frame 230. One end of the fixed frame 230 is rotatably connected to the hull 100. The second hoisting device 220 includes a second traction rope 221. The second traction rope 221 is wound around the hanger 210 and connected to the other end of the fixed frame 230.

[0061] like Figure 1As shown, in this embodiment, it is exemplarily explained that the hull 100 may be provided with a hollow, the fixing frame 230 may be provided at the hollow, and one end thereof may be rotatably connected to the hull 100. The hanger 210 may be provided near the other end of the fixing frame 230, and it may be provided as a structure similar to a gantry. A second traction rope 221 may be provided at the other end of the fixing frame 230, and the second traction rope 221 is used to tow the fixing frame 230, and it may be wound around the hanger 210, and the other end extends along the rotation connection end near the fixing frame 230. The reamer device 240 and the suction device 250 may both be provided at the end of the fixing frame 230 away from its rotation connection end, wherein the reamer device 240 may include a rotatable tool and a reamer driving device, the reamer driving device and the tool are transmitted, and the reamer driving device drives the tool to rotate to achieve the stirring of the sludge. The suction device 250 may include an inlet pipe, a suction pump and an outlet pipe connected in sequence. The suction pump may draw in the stirred muddy water through the inlet pipe and discharge it through the outlet pipe. The outlet pipe may be reasonably wired in the hull 100 to extend its end to a suitable position for discharge. At the same time, a flange or other device may be provided at the end of the outlet pipe to facilitate external piping to discharge the muddy water to a designated position. It is not difficult to see that when dredging is performed, the second traction rope 221 is extended, and the fixing frame 230 rotates under the action of its own weight to lower the reamer device 240 and the suction device 250, thereby facilitating the operation of the reamer device 240 and the suction device 250. When the dredging operation is completed, the second traction rope 221 is shortened, the fixing frame 230 is lifted, and the reamer device 240 and the suction device 250 are stored on the hull 100 under the drive of the fixing frame 230.

[0062] It can be understood that this embodiment, by providing a fixing frame 230 and a second traction rope 221, can realize the lowering and storage of the reamer device 240 and the suction device 250, so as to facilitate the movement of the hull 100 to a designated position, and after fixing it with a positioning pile 500, dredging operations can be performed on the designated position.

[0063] More specifically, the second hoisting device 220 also includes a second drum 222 and a second hoisting drive device. The end of the second traction rope 221 away from the fixed frame 230 is connected to the second drum 222, and the second drum 222 is connected to the second hoisting drive device. The second hoisting drive device drives the second drum 222 to rotate so as to extend or shorten the second traction rope 221.

[0064] like Figure 1 and Figure 2As shown, in this embodiment, it is exemplified that, similarly, the connection mode and driving relationship between the second winch drive device and the second roller 222 are similar to the connection mode and driving relationship between the first winch drive device and the first roller 720; when the second winch device 220 drives the second roller 222 to rotate, the second roller 222 can realize the automatic retraction and release of the second traction rope 221, so as to achieve the purpose of proper traction of the reamer device 240 and the suction device 250.

[0065] It is understandable that, by providing the second hoisting device 220 and the second roller 222, this embodiment can realize automatic retraction and release of the second traction rope 221 and control of the retraction and release speed, thereby making the retraction and release process of the reamer device 240 and the suction device 250 smoother.

[0066] More specifically, a fixed pulley device 211 is provided on the hanger 210 , and the second traction rope 221 is wound around the fixed pulley device 211 .

[0067] like Figure 1 and Figure 2 As shown, in this embodiment, the fixed pulley device 211 can be suspended on the hanger 210, and the second traction rope 221 is wound on the fixed pulley device 211, and can be wound with a plurality of turns to be connected to the hanger 210 at intervals. When the second traction rope 221 is extended and retracted, the second traction rope 221 drives the pulley roller of the fixed pulley device 211, and the fixed pulley device 211 can reduce the friction resistance of the second traction rope 221 during the retraction and release process. At the same time, the fixed pulley device 211 can appropriately limit the second traction rope 221, so that the second traction rope 221 can be more stable when the reamer device 240 and the suction device 250 are retracted and released.

[0068] More specifically, the two first traction ropes 710 are symmetrically distributed on both sides of the second traction rope 221 along the width direction of the hull 100 .

[0069] like Figure 1 As shown, in this embodiment, the second traction rope 221 can be arranged in the longitudinal section at the middle position in the width direction of the hull 100, and the two first traction ropes 710 can be arranged in the longitudinal sections on both sides of the width direction of the hull 100, and are symmetrically distributed. At this time, along the width direction of the hull 100, the two positioning piles 500 and the dredging device 200 are distributed more evenly, and the hull 100 can maintain a high stability during the process of retracting and releasing the positioning piles 500, the process of retracting and releasing the fixing frame 230, the dredging operation, and after the dredging operation is completed.

[0070] Specifically, the dredging device 200 and the two rotating frames 300 are respectively distributed at both ends of the hull 100 in the length direction.

[0071] like Figure 1 and Figure 2 As shown, in this embodiment, the rotation connection position of the fixing frame 230 and the hull 100 can be exemplarily described as the middle position of the length direction of the hull 100, and the fixing frame 230 can extend along one end of the hull 100. Two rotating frames 300 can be arranged at the other end of the hull 100, and when the two rotating frames 300 drive the positioning pile 500 to rotate from vertical to horizontal, the positioning pile 500 can extend from one end of the hull 100 where the rotating frame 300 is located to the other end of the hull 100.

[0072] It can be understood that, in this embodiment, by distributing the dredging device 200 and the two rotating frames 300 at both ends of the length direction of the hull 100 , the stability of the hull 100 can be further improved.

[0073] The implementation principle of a river dredging ship provided in the embodiment of the present application is:

[0074] During the desilting operation, the rotary drive device 400 drives the rotating frame 300 to rotate so that the positioning pile 500 rotates from horizontal to inclined. During the rotation of the rotating frame 300, the first traction rope 710 extends, and the locking device 600 locks and fixes the positioning pile 500. When the positioning pile 500 rotates to an inclined state, the locking device 600 releases the positioning pile 500. During the sliding of the positioning pile 500, the first traction rope 710 further extends and always supports the positioning pile 500. When the middle part of the positioning pile 500 slides to the locking device 600, the locking device 600 locks and fixes the positioning pile 500. Subsequently, the rotary drive device 400 drives the rotating frame 300 to continue rotating so that the positioning pile 500 rotates from an inclined state to a vertical state, and the first traction rope 710 continues to extend and supports the positioning pile 500. When the positioning pile 500 rotates to a vertical state, the locking device 600 releases the positioning pile 500 again. At this time, the vertical positioning pile 500 slides vertically downward relative to the locking device 600 under the action of its own weight to be inserted into the riverbed. Subsequently, the second traction rope 221 is extended, and the fixing frame 230 rotates under the action of its own weight to lower the reamer device 240 and the suction device 250, thereby facilitating the operation of the reamer device 240 and the suction device 250.

[0075] When the dredging operation is completed, the locking device 600 locks and fixes the positioning device, and the rotating drive device 400 drives the rotating frame 300 to rotate, so that the bottom of the positioning pile 500 rotates and slides out from the mud at the bottom of the river to separate from the river bottom, so that the positioning pile 500 can be rotated from vertical to horizontal. In this process, the first traction rope 710 is shortened and the positioning pile 500 is supported. When the positioning pile 500 rotates to the horizontal, the locking device 600 releases the positioning pile 500, and the first traction rope 710 continues to shorten and drag the positioning pile 500. Under the traction of the first traction rope 710, the positioning pile 500 slides horizontally relative to the locking device 600, so that the positioning pile 500 can be arranged on the hull 100. When the bottom of the positioning pile 500 slides to the locking device 600, the locking device 600 locks and fixes the positioning pile 500. Subsequently, the second traction rope 221 is shortened, the fixing frame 230 is lifted, and the reamer device 240 and the suction device 250 are stored on the hull 100 driven by the fixing frame 230 .

[0076] In summary, the present application sets up a rotating frame 300, arranges the positioning pile 500 on the rotating frame 300 through the locking device 600, drives the rotating frame 300 to rotate through the rotating driving device 400, and pulls the positioning pile 500 through the first traction rope 710 of the first traction device, so that the positioning pile 500 can be retracted and released more smoothly during the process of retracting and releasing the positioning pile 500, thereby improving the problem that the positioning pile 500 is difficult to control during the process of retracting and releasing.

[0077] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
