[0002] Crushed stone foundations are commonly used in underwater structures, and leveling these foundations is a crucial step in foundation construction, directly impacting the quality and safety of the underwater structure. Leveling operations typically utilize leveling vessels. To facilitate leveling in restricted areas such as rivers, lakes, reservoirs, and inland waterways, leveling vessels equipped with tilting leveling devices have been developed. Examples include the tilting device and vessel for stone-throwing leveling disclosed in patent CN111305217A. However, the tilting devices used in patent CN111305217A have complex structures, require significant power for tilting, and involve complex tilting operations. To simplify the structure of the tilting device, patent CN220225210U discloses a tilting leveling device. Although this tilting leveling device uses a tilting drive mechanism that combines a winch with a tilting traction rope, greatly simplifying the structure, it can only be used on a moon pool and is only suitable for leveling boats with a moon pool in the middle. It cannot be installed on the side of the boat and is not applicable to leveling boats where the leveling device is located on one side of the hull. Therefore, how to simplify the structure of the tilting leveling device located on the side of the leveling boat is a technical problem that urgently needs to be solved. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] As attached Figures 1-6 As shown in an illustrative embodiment of the ship-side tilting leveling device 1 of the present invention, the ship-side tilting leveling device 1 includes a track 11, a moving trolley 12, a constraint frame 13, a leveling actuator 14, and a tilting drive mechanism 16. The moving trolley 12 is movably connected to the track 11 to move along the track 11. The constraint frame 13 is located outside the moving trolley 12 and is rotatably connected to the moving trolley 12 via a rotating shaft 131. The rotating shaft 131 is fixedly connected to the constraint frame 13, and the axis of the rotating shaft 131 is arranged in the horizontal direction. The leveling actuator 14 includes a leveling tube 141 and a leveling head 142. The leveling tube 141 passes through the constraint frame 13 to move and tilt synchronously with the constraint frame 13. The axis of the leveling tube 141 is perpendicular to the axis of the rotating shaft 131, and the leveling head 142 is connected to the axis of the leveling tube 141. To one end; the flipping drive mechanism 16 is used to drive the rotating shaft 131 to rotate the constraint frame 13, so that the leveling actuator 14 can switch between working and non-working states. It includes a swing arm 161 and a telescopic member 162. The swing arm 161 is fixedly connected to the outer periphery of the rotating shaft 131. One end of the telescopic member 162 is hinged to the moving trolley 12, and the other end is hinged to the end of the swing arm 161 away from the rotating shaft 131. The telescopic member 162 extends and retracts in a vertical plane perpendicular to the axis of the rotating shaft 131 to drive the swing arm 161 to drive the rotating shaft 131 to swing around the axis of the rotating shaft 131 between a first position and a second position. When the swing arm 161 is in the first position, the leveling tube 141 is in a vertical state and the leveling head 142 is located at the bottom end of the leveling tube 141. When the swing arm 161 is in the second position, the leveling tube 141 is in a horizontal state.

[0047] The aforementioned ship-side tilting leveling device 1 has a constraint frame 13 connected to the outside of a moving trolley 12 via a rotating shaft 131. A tilting drive mechanism 16 drives the constraint frame 13 to rotate relative to the moving trolley 12, thereby causing the leveling actuator 14 to tilt on the ship side. This allows the leveling actuator 14 to switch between working and non-working states. In the tilting drive mechanism 16, the extension and retraction of the telescopic member 162 causes the swing arm 161 to swing, which in turn drives the rotating shaft 131 to rotate, thus achieving the tilting of the constraint frame 13 relative to the moving trolley 12. The tilting structure is simple, and the tilting drive is convenient. Furthermore, the aforementioned ship-side tilting leveling device 1, which uses the extension and retraction of the telescopic member 162 to drive the tilting of the constraint frame 13 and the leveling actuator 14, has low energy consumption and low cost.

[0048] To facilitate the connection of the rotating shaft 131 to the mobile trolley 12, and also to facilitate the installation of the tilting drive mechanism 16, such as... Figures 3-6 As shown, the movable trolley 12 has a connecting frame 15 on the side facing the constraint frame 13. The connecting frame 15 includes a base plate 151, a first upright 152 and a second upright 153 disposed opposite to each other on the base plate 151, and a top frame 155 connecting the top of the first upright 152 and the top of the second upright 153. The first upright 152 is located on the side away from the movable trolley 12 and has a first rotating shaft connecting plate 1521. The second upright 153 is located on the side closer to the movable trolley 12 and has a connecting plate 1521 for the first rotating shaft. The connecting plate 1521 is opposite to the second rotating shaft connecting plate 1531. The rotating shaft 131 is fixedly connected to the side of the constraint frame 13 facing the moving trolley 12. The rotating shaft 131 passes through and is rotatably connected to the first rotating shaft connecting plate 1521 and the second rotating shaft connecting plate 1531 in sequence. The swing arm 161 is connected to the outer periphery of the portion of the rotating shaft 131 located between the first rotating shaft connecting plate 1521 and the second rotating shaft connecting plate 1531. The bottom end of the telescopic member 162 is hinged to the base plate 151, and the top end of the telescopic member 162 is hinged to the end of the swing arm 161 away from the rotating shaft 131. In this embodiment, the first upright 152 and the second upright 153 of the connecting frame 15 provide connection support points for the connection of the rotating shaft 131. At the same time, the space formed between the base plate 151, the first upright 152, the second upright 153 and the top frame 155 of the connecting frame 15 provides installation space for the tilting drive mechanism 16.

[0049] Furthermore, such as Figure 5 As shown, the upper part of the connecting frame 15 protrudes from the top surface of the moving trolley 12, and a diagonal brace 154 connects the upper part of the connecting frame 15 and the top surface of the moving trolley 12. The diagonal brace 154 strengthens the connection between the connecting frame 15 and the moving trolley 12 and resists the tensile force on the connecting frame 15 due to the connection of the constraint frame 13 through the pivot 131.

[0050] To ensure sufficient connection strength between the swing arm 161 and the rotating shaft 131 to drive the rotating shaft 131 to rotate, such as Figure 6 As shown, the swing arm 161 includes a fixed part 1611 sleeved on the outer periphery of the rotating shaft 131, and a swing part 1612 connected to the fixed part 1611 and extending outward from the outer periphery of the rotating shaft 131 radially.

[0051] To facilitate the swinging of the swing arm 161 via the telescopic drive of the telescopic component 162, such as Figure 6 As shown, the extending direction of the swing part 1612 is angled with the vertical direction so that the swing part 1612 is located to the side of the rotating shaft 131, and the telescopic member 162 is located on one side of the rotating shaft 131 and on the same side as the swing part 1612. Preferably, the telescopic member 162 is a hydraulic telescopic rod.

[0052] To facilitate the hinged connection between the swing arm 161 and the telescopic component 162, such as Figure 4 As shown, there are two swing arms 161. The swing portions 1612 of the two swing arms 161 extend in the same direction and are arranged opposite to each other. A hinge post 163 for hinged telescopic member 162 is connected between the ends of the swing portions 1612 of the two swing arms 161 away from the fixed portion 1611.

[0053] In addition, such as Figure 1 As shown, the leveling actuator 14 further includes a lifting assembly 143 for driving the leveling pipe 141 to rise and fall relative to the constraint frame 13 when the leveling pipe 141 is in a vertical state. The lifting assembly 143 includes a lifting traction rope 1432 for pulling the leveling pipe 141 up and down and a lifting winch 1431 for winding and unwinding the lifting traction rope 1432. The lifting winch 1431 is installed at the end of the mobile trolley 12 away from the constraint frame 13, and the lifting traction rope 1432 is connected between the lifting winch 1431 and the leveling pipe 141. In this embodiment, the leveling pipe 141 is driven to rise and fall by winding and unwinding the lifting traction rope 1432 by the lifting winch 1431, thereby realizing the leveling operation. Meanwhile, in this embodiment, the lifting winch 1431 is installed at the end of the mobile trolley 12 away from the constraint frame 13, which serves as a counterweight and helps to keep the mobile trolley 12 balanced. It also eliminates the need to reserve an installation position for the lifting winch 1431 on the constraint frame 13, which helps to reduce the size and weight of the constraint frame 13.

[0054] Based on the above-described ship-side tilting leveling device 1, the present invention also provides a tilting method for the ship-side tilting leveling device, applied to the above-described ship-side tilting leveling device 1. The tilting method includes a tilting method for tilting the leveling actuator 14 from a non-working state to a working state, and a tilting method for tilting the leveling actuator 14 from a working state to a non-working state; wherein, in the working state, the leveling tube 141 of the leveling actuator 14 is in a vertical state; in the non-working state, the leveling tube 141 of the leveling actuator 14 is in a horizontal state.

[0055] The flipping method from non-working state to working state includes the following steps: the telescopic component 162 drives the swing arm 161 to drive the rotating shaft 131 to rotate from the second position to the first position around the axis of the rotating shaft 131. The rotating shaft 131 simultaneously drives the constraint frame 13 and the leveling actuator 14 to flip relative to the moving trolley 12, so that the leveling tube 141 is in a vertical state and enters the working state.

[0056] The flipping method from working state to non-working state includes the following steps: the telescopic component 162 drives the swing arm 161 to rotate the rotating shaft 131 around the axis of the rotating shaft 131 from the first position to the second position. The rotating shaft 131 simultaneously drives the constraint frame 13 and the leveling actuator 14 to flip relative to the moving trolley 12, so that the leveling tube 141 is in a horizontal state and enters the non-working state.

[0057] The above-mentioned ship-side tilting leveling device tilting method involves the telescopic drive arm 161 of the telescopic component 162 swinging between the first and second positions to drive the rotating shaft 131, the constraint frame 13 and the leveling actuator 14 to tilt synchronously. The tilting drive method is simple and easy to control.

[0058] Based on the aforementioned ship-side tilting leveling device 1, such as Figure 7 and Figure 8 As shown, the present invention also provides a gravel bed leveling vessel, including a hull 2. A side-tilting leveling device 1 is installed on one side of the hull 2. The track 11 of the side-tilting leveling device 1 is laid along the length of the hull 2 ​​and positioned close to one side of the hull. A constraint frame 13 and a leveling actuator 14 are both located on the outer side of the hull 2. The axis of the rotating shaft 131 is arranged along the width of the hull 2, so that the constraint frame 13 and the leveling actuator 14 can be tilted in the vertical plane relative to the hull 2 ​​on the outer side of the hull. This gravel bed leveling vessel features a simple tilting structure, convenient tilting drive, low energy consumption, and low cost for its side-tilting leveling device 1.

[0059] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
