Description

Technical Field

[0001] The present invention belongs to the technical field of bed leveling, and in particular relates to a turning method of a turning type leveling device. Background Art

[0002] Gravel bed is a common foundation for underwater structures. Leveling the gravel bed is a crucial step in foundation construction, directly impacting the quality and safety of underwater structures. Gravel bed leveling is typically performed using a leveling vessel. To facilitate leveling operations in restricted areas such as rivers, lakes, reservoirs, and inland waterways, Patent CN210887224U discloses a riprap leveling vessel. A rotating mechanism drives a riprap leveling actuator to rotate within a vertical plane, switching the actuator between an active and inactive state. In the inactive state, the actuator rests horizontally on the hull, resulting in a lower overall height for the riprap leveling vessel, reducing navigational restrictions and expanding the range of waters within which it can operate. Patent CN111305217A discloses a flipping device for a riprap leveling vessel that also flips the leveling mechanism. However, the rotating mechanism or flipping device used in existing leveling vessels is relatively complex, making the flipping operation complex and requiring significant power.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0044] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0045] As attached Figure 1-Figure 7 As shown, in an exemplary embodiment of a flipping method of a flipping leveling device of the present invention, the applicable flipping leveling device 1 includes a traveling trolley 11, a traveling trolley 12, a leveling actuator 13 and a flipping drive mechanism 14; the traveling trolley 11 is erected transversely above the moon pool of the hull 2, and includes two track beams 111 arranged opposite to each other, and opposite sides of the two track beams 111 are provided with tracks 1111 extending transversely; the traveling trolley 12 is connected between the two tracks 1111 of the traveling trolley 11 via trolley track wheels 121; the leveling actuator 13 is mounted on the traveling trolley 12 and can be raised and lowered relative to the traveling trolley 12; the flipping drive mechanism 14 includes a first winch 141 provided on the traveling trolley 11, and a flipping traction rope 142 connected between the first winch 141 and the top of the leveling actuator 13;

[0046] The flipping method includes a flipping method of flipping the leveling actuator 13 from a non-working state to a working state, and a flipping method of flipping from a working state to a non-working state; wherein, in the working state, the leveling actuator 13 is vertically arranged to pass through the moon pool for leveling operations; in the non-working state, the leveling actuator 13 flips to above the moon pool;

[0047] The flipping method from the non-working state to the working state includes the following steps: the first hoist 141 releases the flipping traction rope 142, and under the action of the gravity of the leveling actuator 13, the leveling actuator 13 and the traveling trolley 12 flip in a vertical plane relative to the traveling trolley 11 with the wheel axle of the trolley track wheel 121 as the axis until the leveling actuator 13 is vertical and enters the working state;

[0048] The flipping method from the working state to the non-working state includes the following steps: the first winch 141 reels the flipping traction rope 142, and under the tension of the flipping traction rope 142, the leveling actuator 13 and the walking trolley 12 flip in the vertical plane relative to the walking trolley 11 with the axle of the trolley track wheel 121 as the axis, until the leveling actuator 13 flips to above the moon pool and enters the non-working state.

[0049] The flipping method of the aforementioned flip-type leveling device utilizes the trolley track wheels 121 provided on both sides of the trolley 12 to cooperate with the tracks 1111 of the two track beams 111 of the traveling trolley 11, thereby achieving flipping of the leveling actuator 13 relative to the traveling trolley 11 using the wheel axles of the trolley track wheels 121 as the axis. This does not hinder the movement of the trolley 12 along the traveling trolley 11, resulting in a simple flipping method and high flipping efficiency. Furthermore, the flipping method of the aforementioned flip-type leveling device 1 utilizes a flipping control method that cooperates with the first winch 141 and the flipping traction rope 142, eliminating the need for large flipping power and reducing construction costs.

[0050] In some embodiments, as Figure 4-Figure 7 As shown, the traveling trolley 11 is provided with a flip position at the part directly above the moon pool, and each track beam 111 is detachably connected to a limiting assembly 112 corresponding to the flip position; before the leveling actuator 13 flips, it also includes: the traveling trolley 12 drives the leveling actuator 13 to move to the flip position, and the trolley track wheel 121 is limited to the flip position by the limiting assembly 112. By limiting the position of a trolley track wheel 121 by the provided limiting assembly 112, the traveling trolley 12 can be limited to the flip position, which facilitates the control of the flipping of the leveling actuator 13. Preferably, the flip position is located in the middle of the traveling trolley 11, which can prevent the hull 2 ​​from interfering with the flipping of the leveling actuator 13. It should be noted that the walking trolley 12 can drive the trolley track wheel 121 to rotate through its own power equipment, so that the walking trolley 12 drives the leveling actuator 13 to move along the walking trolley 11; when the walking trolley 12 is not equipped with a power device or the power is insufficient, the walking trolley 12 and the leveling actuator 13 can also be pulled along the walking trolley 11 by another power equipment.

[0051] Specifically, such as Figure 5As shown, in this embodiment, the limiting assembly 112 includes a pair of limiting rods 1121. When limiting the position of the trolley track wheel 121, the pair of limiting rods 1121 are respectively located on both sides of the trolley track wheel 121 and respectively abut against both sides of the trolley track wheel 121. By using the pair of limiting rods 1121 as the limiting assembly 112, the trolley 12 can be limited to the flip position by limiting the trolley track wheel 121 between the two limiting rods 1121. The structure is simple and easy to operate.

[0052] In some embodiments, as Figure 5 and Figure 7 As shown, there are two trolley track wheels 121 connected to each track 1111, and each track beam 111 is further provided with a notch a corresponding to another trolley track 1111 at the position corresponding to the flipping position, and the notch a is located above the track 1111 and is connected to the track 1111; when the traveling trolley 12 drives the leveling actuator 13 to move to the flipping position, one trolley track wheel 121 is restricted in the flipping position by the limiting assembly 112, and the other trolley track wheel 121 is located below the notch a; when the traveling trolley 12 flips, the unrestricted trolley track wheel 121 flips out of the track 1111 through the notch a above it. Each side of the walking trolley 12 is connected to the track 1111 of the track beam 111 of the walking trolley 11 through two trolley track wheels 121, which can ensure the stability of the walking trolley 12 moving along the walking trolley 11. At the same time, when one trolley track wheel 121 is restricted to the flipping position by the limiting component 112, by setting the gap a, the other trolley track wheel 121 can be flipped out of the track 1111 when the walking trolley 12 is flipped. In this way, the flipping of the walking trolley 12 is achieved while ensuring the stability of the walking trolley 12 moving along the walking trolley 11, and the flipping structure is simple.

[0053] Further, such as Figure 5 As shown, a cover plate 113 for opening or covering the gap a is provided at the gap a. The cover plate 113 is detachably connected to the gap a. Before the trolley 12 is turned over, the cover plate 113 is opened to open the gap a. The provided cover plate 113 allows the gap a to be opened when the trolley 12 needs to be turned over. While the trolley 12 moves along the traveling carriage 11, the cover plate 113 covers the gap a, keeping the top of the track 1111 closed and preventing debris from falling into the track 1111 and affecting the movement of the trolley 12.

[0054] In some embodiments, as Figure 2As shown, the flip drive mechanism 14 further includes a reaction frame 143 connected to the traveling trolley 11. The reaction frame 143 is confined near the first hoist 141, and the flip traction rope 142 passes around the reaction frame 143 from below. By applying a reaction force to the flip traction rope 142 by the provided reaction frame 143, the force required by the first hoist 141 to pull the leveling actuator 13 to flip can be reduced.

[0055] In some embodiments, in order to keep the leveling actuator 13 in the non-operating state, after the leveling actuator 13 is flipped to the non-operating state, the leveling actuator 13 is further fixed to the traveling trolley 11 by a locking member. Specifically, the locking member includes a locking wire rope connected between the top end of the leveling actuator 13 and the traveling trolley 11.

[0056] In some embodiments, in the flipping method from the working state to the non-working state, before flipping the leveling actuator 13, the method further includes controlling the leveling actuator 13 to rise and fall relative to the traveling trolley 12 so that the traveling trolley 12 is located in the middle of the leveling actuator 13. It should be noted that in this embodiment, if Figure 2 As shown, the first hoist 141 is arranged at one end of the traveling trolley 11. When the leveling actuator 13 flips, the leveling actuator 13 needs to flip downward from the side away from the first hoist 141. Therefore, before driving the leveling actuator 13 to flip, it is necessary to ensure that the weight of the part of the leveling actuator 13 located below the traveling trolley 12 in the working state (that is, the part of the leveling actuator 13 located on the side of the traveling trolley 12 away from the first hoist 141 in the non-working state) is greater than the weight of the part of the leveling actuator 13 located above the traveling trolley 12 (that is, the part of the leveling actuator 13 located on the side of the traveling trolley 12 close to the first hoist 141 in the non-working state), so as to avoid the leveling actuator 13 from flipping from the side close to the first hoist 141. Since the lower part of the leveling actuator 13 is heavier than the upper part due to the leveling head 132, the leveling actuator 13 can be raised and lowered so that the traveling trolley 12 is located in the middle of the leveling actuator 13 to prevent the leveling actuator 13 from flipping over from the side close to the first winch 141.

[0057] Specifically, in this embodiment, Figure 3As shown, the leveling actuator 13 includes a slide 131, a leveling head 132 and a lifting assembly 133. The slide 131 is passed through the traveling trolley 12 and can be raised and lowered relative to the traveling trolley 12. The leveling head 132 is connected to the bottom of the slide 131. The lifting assembly 133 includes a second winch 1331 fixedly installed on the traveling trolley 12 and a lifting rope 1332 connected between the slide 131 and the second winch 1331; the lifting rope 1332 is retracted and extended by the second winch 1331 so that the traveling trolley 12 is located in the middle of the slide 131.

[0058] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the same. Although the present invention has been described in detail with reference to preferred embodiments, persons skilled in the art should understand that the specific implementation methods of the present invention may still be modified or some technical features may be replaced by equivalents without departing from the spirit of the technical solutions of the present invention, and all of these should fall within the scope of the technical solutions claimed for protection by the present invention.
