Description

Technical Field

[0001] The invention belongs to the technical field of bed leveling, and particularly relates to a flipping type leveling device, a leveling ship and a leveling construction method thereof. Background Art

[0002] A rubble bed is a common foundation for underwater buildings. The rubble bed leveling operation is an important process in foundation construction, which directly affects the construction quality and safety of underwater buildings.

[0003] A leveling ship is an engineering ship for carrying out rubble bed leveling operations. There are mainly two types of existing leveling ships. One is a leveling ship with a leveling actuator located outside the ship's side (see patent CN210887224U). Its leveling actuator can only move in a straight line, with a small leveling range, and it needs to move the ship multiple times, resulting in low leveling construction efficiency. The other is a leveling ship with a leveling actuator moving in the ship's moonpool (see patent CN112392091A). It can level the bed under the surrounding area of the moonpool with high leveling efficiency. However, for the rubble bed used in a immersed tube tunnel, part of the bed is close to or located in the precast dock. Since the leveling ship cannot enter the precast dock for leveling construction, this part of the bed is usually leveled manually, but the manual leveling efficiency is low. If it is necessary to realize the conversion of the leveling actuator working on both sides inside and outside the moonpool, it is necessary to realize the flipping of the leveling actuator at two positions inside and outside the moonpool and the rapid movement of the leveling actuator between the two flipping positions. However, this requires at least a set of flipping drive mechanism for driving the leveling actuator to flip and a set of translation drive mechanism for driving the leveling actuator to translate rapidly, with a complex drive structure and high cost.

[0004] Therefore, how to provide a flipping type leveling device that can flip at two positions inside and outside the moonpool on the premise of low cost to improve the leveling efficiency of the leveling ship and broaden the applicable range of the leveling ship is a technical problem that urgently needs to be solved at present. Summary of the Invention

[0005] Aiming at the above technical problems, the invention provides a flipping type leveling device, a leveling ship and a leveling construction method thereof. Through a set of drive mechanism, the leveling actuator is driven to flip at two positions inside and outside the moonpool and the rapid movement of the leveling actuator between the two flipping positions, realizing the leveling construction of the bed under the surrounding area of the moonpool and the leveling construction of a small range of bed outside the surrounding area of the moonpool on the premise of low cost, improving the leveling efficiency of the leveling ship and broadening the applicable range of the leveling ship.

[0006] The invention provides a flipping type leveling device, comprising:

[0007] The traveling carriage is horizontally installed above the moon pool of the hull and moves longitudinally relative to the hull. One end of the traveling carriage extends outside the moon pool. The traveling carriage is provided with a flipping position, and the flipping position includes a first flipping position provided at the part of the traveling carriage directly above the moon pool and a second flipping position provided at the part of the traveling carriage extending outside the moon pool.

[0008] The traveling trolley is connected to the traveling carriage. The traveling trolley moves along the traveling carriage and flips in the vertical plane relative to the traveling carriage at the first flipping position and the second flipping position.

[0009] The leveling actuator is installed on the traveling trolley and can be lifted and lowered relative to the traveling trolley. The leveling actuator flips relative to the traveling carriage through the traveling trolley to switch between the working state and the non-working state. In the working state, the leveling actuator is vertically arranged to perform leveling operations. In the non-working state, the leveling actuator flips above the moon pool.

[0010] The driving mechanism is used to drive the leveling actuator to flip at the first flipping position or the second flipping position, and to drive the leveling actuator to move from the first flipping position to the second flipping position. It includes a first winch provided at the lateral end of the traveling carriage far from the second flipping position, a traction wheel provided at the lateral end of the traveling carriage close to the second flipping position, and a traction rope connected to the first winch.

[0011] Wherein, when the driving mechanism is used to drive the leveling actuator to flip, the end of the traction rope far from the first winch is connected to the top end of the leveling actuator. The first winch drives the leveling actuator and the traveling trolley to flip relative to the traveling carriage by winding and unwinding the traction rope. When the driving mechanism is used to drive the leveling actuator to move, the end of the traction rope far from the first winch bypasses the traction wheel and is connected to the side of the traveling trolley facing away from the first winch. The first winch drives the leveling actuator and the traveling trolley to move along the traveling carriage from the first flipping position to the second flipping position by winding the traction rope.

[0012] In some embodiments, the driving mechanism further includes a reaction frame connected to the traveling carriage. The reaction frame moves along the traveling carriage. When the driving mechanism is used to drive the leveling actuator to flip, the traction rope bypasses the reaction frame from below. When the leveling actuator flips at the first flipping position, the reaction frame is restricted near the first winch. When the leveling actuator flips at the second flipping position, the reaction frame is restricted at the first flipping position. When the driving mechanism is used to drive the leveling actuator to move, the reaction frame is connected to the leveling actuator through a locking steel wire rope to move with the leveling actuator.

[0013] In some of these embodiments, the traveling gantry includes two oppositely arranged track beams, the two track beams are horizontally installed on the hull along the transverse direction, and the opposite side surfaces of the two track beams are both provided with tracks extending along the transverse direction; the traveling trolley is connected between the two tracks of the traveling gantry through trolley track wheels to move along the tracks, and the traveling trolley rotates relative to the traveling gantry in the vertical plane with the axle of the trolley track wheels as the axis; the reaction frame is connected between the two tracks of the traveling gantry through reaction frame track wheels to move along the tracks.

[0014] In some of these embodiments, a limiting component is detachably connected to each track beam corresponding to the flipping position. When the traveling trolley flips at the first flipping position, the limiting component arranged at the first flipping position is used to limit one trolley track wheel at the first flipping position; when the traveling trolley flips at the second flipping position, the limiting component arranged at the first flipping position is used to limit the reaction frame track wheel at the first flipping position, and the limiting component arranged at the second flipping position is used to limit one trolley track wheel at the second flipping position.

[0015] In some of these embodiments, the limiting component includes a pair of limiting rods arranged in pairs; when limiting the position of the trolley track wheel, the pair of limiting rods are respectively located on both sides of the trolley track wheel and are respectively abutted against both sides of the trolley track wheel; when limiting the position of the reaction frame track wheel, the pair of limiting rods are respectively located on both sides of the reaction frame track wheel and are respectively abutted against both sides of the reaction frame track wheel.

[0016] In some of these embodiments, there are two trolley track wheels connected to each track, and each track beam corresponding to the flipping position is further provided with a notch for another trolley track wheel to turn out of the track, and the notch is located above the track and communicates with the track.

[0017] Furthermore, the present invention also provides a leveling ship, including a hull, a moonpool is arranged on the hull, and the above-mentioned flip-type leveling device is installed on the moonpool.

[0018] In addition, the present invention also provides a leveling construction method for a leveling ship, including the leveling construction of the bed within the surrounded area of the moonpool and the leveling construction of the bed outside the surrounded area of the moonpool; wherein,

[0019] The construction steps for leveling the bed within the enclosed area of the moon pool include: The traveling trolley drives the leveling actuator in a non-working state to move to the first flipping position, and connects one end of the towing rope away from the first winch to the top of the leveling actuator; The first winch releases the towing rope. Under the gravity of the leveling actuator, the leveling actuator drives the traveling trolley to flip relative to the traveling carriage in the vertical plane at the first flipping position until the leveling actuator becomes vertical and enters the working state; By moving the traveling carriage longitudinally relative to the hull and the traveling trolley moving along the traveling carriage, the working position of the leveling actuator is adjusted to level the bed within the enclosed area of the moon pool; After the leveling operation, the first winch winds up the towing rope. Under the pulling force of the towing rope, the leveling actuator drives the traveling trolley to flip relative to the traveling carriage in the vertical plane until the leveling actuator flips above the moon pool and enters the non-working state.

[0020] The construction steps for leveling the bed outside the enclosed area of the moon pool include: Pass one end of the towing rope away from the first winch around the towing wheel and connect it to the side of the traveling trolley away from the first winch. The first winch winds up the towing rope to pull the traveling trolley to drive the leveling actuator in a non-working state to move along the traveling carriage to the second flipping position, and connect one end of the towing rope away from the first winch to the top of the leveling actuator; The first winch releases the towing rope. Under the gravity of the leveling actuator, the leveling actuator drives the traveling trolley to flip relative to the traveling carriage in the vertical plane at the second flipping position until the leveling actuator becomes vertical and enters the working state; By moving the traveling carriage longitudinally relative to the hull, the working position of the leveling actuator is adjusted to level the bed outside the enclosed area of the moon pool; After the leveling operation, the first winch winds up the towing rope. Under the pulling force of the towing rope, the leveling actuator drives the traveling trolley to flip relative to the traveling carriage in the vertical plane until the leveling actuator flips above the moon pool and enters the non-working state.

[0021] In some of these embodiments, during the leveling construction step of the bed within the enclosed area of the moonpool, it further includes restricting the reaction frame near the first winch; when connecting the towing rope to the top of the leveling actuator, making the towing rope pass under the reaction frame; when the leveling actuator flips, the reaction frame applies a downward force to the towing rope; during the leveling construction step of the bed outside the enclosed area of the moonpool, before connecting the towing rope to the traveling trolley, it further includes connecting the reaction frame to the leveling actuator through a locking steel wire rope; when the first winch winds up the towing rope to pull the traveling trolley to move to the second flipping position, the leveling actuator pulls the reaction frame to move to the first flipping position through the locking steel wire rope; after the reaction frame moves to the first flipping position, restricting the reaction frame at the first flipping position; when connecting the towing rope to the top of the leveling actuator, making the towing rope pass under the reaction frame; when the leveling actuator flips, the reaction frame applies a downward force to the towing rope.

[0022] In some of these embodiments, when the leveling actuator flips at the first flipping position, it further includes restricting one trolley track wheel of the traveling trolley at the first flipping position through the limiting component provided at the first flipping position, and making the other trolley track wheel of the traveling trolley located below the notch provided at the first flipping position. The leveling actuator and the traveling trolley flip relative to the traveling barge with the axle of the restricted trolley track wheel as the axis, and the unrestricted trolley track wheel flips out of the track through the notch above it; when the leveling actuator flips at the second flipping position, it further includes restricting the reaction frame track wheel of the reaction frame at the first flipping position through the limiting component provided at the first flipping position, restricting one trolley track wheel of the traveling trolley at the second flipping position through the limiting component provided at the second flipping position, and making the other trolley track wheel of the traveling trolley located below the notch provided at the second flipping position. The leveling actuator and the traveling trolley flip relative to the traveling barge with the axle of the restricted trolley track wheel as the axis, and the unrestricted trolley track wheel flips out of the track through the notch above it.

[0050] Next, the technical solutions in the embodiments will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0052] The terms "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0053] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention may be understood according to specific circumstances.

[0054] As attached Figures 1-13As shown, in a schematic embodiment of the flip-type leveling device 1 of the present invention, the flip-type leveling device 1 includes a traveling carriage 11, a traveling trolley 12, a leveling execution mechanism 13, and a driving mechanism 14; the traveling carriage 11 is horizontally installed above the moon pool of the hull 2 and moves longitudinally relative to the hull 2. One end of the traveling carriage 11 extends outside the moon pool. The traveling carriage 11 is provided with a flipping position, and the flipping position includes a first flipping position provided on the part of the traveling carriage 11 located directly above the moon pool and a second flipping position provided on the part of the traveling carriage 11 extending outside the moon pool; the traveling trolley 12 is connected to the traveling carriage 11, the traveling trolley 12 moves along the traveling carriage 11, and flips relative to the traveling carriage 11 in the vertical plane at the first flipping position and the second flipping position; the leveling execution mechanism 13 is installed on the traveling trolley 12 and can be lifted relative to the traveling trolley 12. The leveling execution mechanism 13 flips relative to the traveling carriage 11 through the traveling trolley 12 to switch between the working state and the non-working state; in the working state, the leveling execution mechanism 13 is vertically arranged for leveling operation; in the non-working state, the leveling execution mechanism 13 flips above the moon pool; the driving mechanism 14 is used to drive the leveling execution mechanism 13 to flip at the first flipping position or the second flipping position, and to drive the leveling execution mechanism 13 to move from the first flipping position to the second flipping position. It includes a first winch 141 provided at the transverse end of the traveling carriage 11 away from the second flipping position, a traction wheel 142 provided at the transverse end of the traveling carriage 11 close to the second flipping position, and a traction rope 143 connected to the first winch 141; wherein, when the driving mechanism 14 is used to drive the leveling execution mechanism 13 to flip, the end of the traction rope 143 away from the first winch 141 is connected to the top end of the leveling execution mechanism 13, and the first winch 141 drives the leveling execution mechanism 13 and the traveling trolley 12 to flip relative to the traveling carriage 11 by winding and unwinding the traction rope 143; when the driving mechanism 14 is used to drive the leveling execution mechanism 13 to move, the end of the traction rope 143 away from the first winch 141 bypasses the traction wheel 142 and is connected to the side of the traveling trolley 12 facing away from the first winch 141, and the first winch 141 drives the leveling execution mechanism 13 and the traveling trolley 12 to move along the traveling carriage 11 from the first flipping position to the second flipping position by winding the traction rope 143.

[0055] The above-mentioned flipping type leveling device 1 has a first flipping position of the traveling carriage 11 above the moon pool and a second flipping position outside the moon pool. The leveling actuator 13 flips to the working state at the first flipping position, realizing the leveling construction of the foundation bed under the surrounded area of the moon pool. The leveling actuator 13 flips to the working state at the second flipping position, realizing the leveling construction of a small area of the foundation bed outside the surrounded area of the moon pool, greatly improving the leveling efficiency and the leveling range. Moreover, for the above-mentioned flipping type leveling device 1, a set of driving mechanism 14 drives the flipping of the leveling actuator 13 and the rapid movement of the leveling actuator 13 between the first flipping position and the second flipping position. Its driving structure is simple and no large flipping power is required, realizing the leveling construction of the foundation bed under the surrounded area of the moon pool and the leveling construction of a small area of the foundation bed outside the surrounded area of the moon pool on the premise of low cost. Further, for the above-mentioned flipping type leveling device 1, when the leveling actuator 13 flips to the non-working state above the moon pool of the hull 2, its overall height is relatively low, reducing the requirements for the water depth and the clearance height of the construction area, and enabling construction in a limited construction water area, with a wide range of applications.

[0056] In order to reduce the acting force required for the first hoist 141 to pull the leveling actuator 13 to flip, such as Figure 1 , Figure 8 , Figure 9 , Figure 11 and Figure 12As shown, the driving mechanism 14 further includes a reaction frame 144 connected to the traveling gantry 11, and the reaction frame 144 moves along the traveling gantry 11; when the driving mechanism 14 is used to drive the leveling actuator 13 to flip, the traction rope 143 bypasses the reaction frame 144 from below the reaction frame 144; when the leveling actuator 13 flips at the first flipping position, the reaction frame 144 is restricted to be near the first winch 141; when the leveling actuator 13 flips at the second flipping position, the reaction frame 144 is restricted to the first flipping position; when the driving mechanism 14 is used to drive the leveling actuator 13 to move, the reaction frame 144 is connected to the leveling actuator 13 through a locking steel wire rope 145 to move along with the leveling actuator 13. By applying a reaction force to the traction rope 143 through the provided reaction frame 144, the acting force required for the first winch 141 to pull the leveling actuator 13 to flip can be reduced. It should be noted that when the leveling actuator 13 flips at the second flipping position, restricting the reaction frame 144 to the first flipping position can make a more appropriate angle formed between the parts of the traction rope 143 on both sides of the reaction frame 144 to achieve a more labor-saving state. Preferably, the first flipping position is located in the middle of the traveling gantry 11. On the one hand, it can prevent the hull 2 from interfering with the flipping of the leveling actuator 13, and on the other hand, it can achieve a more labor-saving state when the reaction frame 144 stays at the first flipping position. It should also be noted that when moving the leveling actuator 13 and the traveling trolley 12 to the second flipping position, connecting the reaction frame 144 to the leveling actuator 13 by using the locking steel wire rope 145 can make the reaction frame 144 follow the traveling trolley 12 and the leveling actuator 13 to move to the first flipping position without additionally driving the driving structure for the reaction frame 144 to move.

[0057] The following describes the specific flipping method of the traveling trolley 12 relative to the traveling gantry 11:

[0058] As Figure 1 、 Figure 3 、 Figure 12As shown in the figure, the traveling carriage 11 includes two oppositely arranged track beams 111. The two track beams 111 are horizontally installed on the hull 2. The opposite sides of the two track beams 111 are both provided with tracks 1111 extending horizontally. The traveling trolley 12 is connected between the two tracks 1111 of the traveling carriage 11 through trolley track wheels 121 to move along the tracks 1111. The traveling trolley 12 rotates relative to the traveling carriage 11 in the vertical plane with the axle of the trolley track wheels 121 as the axis. The reaction frame 144 is connected between the two tracks 1111 of the traveling carriage 11 through reaction frame track wheels 1442 to move along the tracks 1111. In this embodiment, by the cooperation of the trolley track wheels 121 arranged on both sides of the traveling trolley 12 and the tracks 1111 of the two track beams 111 of the traveling carriage 11, on the one hand, the movement of the traveling trolley 12 along the traveling carriage 11 can be realized, and on the other hand, the rotation of the traveling trolley 12 relative to the traveling carriage 11 can be realized with the axle of the trolley track wheels 121 as the axis. At the same time, the reaction frame 144 is matched with the tracks 1111 of the two track beams 111 of the traveling carriage 11 through the reaction frame track wheels 1442 to realize the movement of the reaction frame 144 along the traveling carriage 11. It should be noted that, as Figure 12 shown, the reaction frame 144 further includes a frame body 1441 connected between the two reaction frame track wheels 1442, and the towing rope 143 bypasses the frame body 1441. It should also be noted that, as Figure 4 and Figure 6 shown, when the leveling actuator 13 rotates, the leveling actuator 13 needs to rotate downward from the side away from the first winch 141. Therefore, before driving the leveling actuator 13 to rotate, 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 away from the first winch 141 of the traveling trolley 12 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 close to the first winch 141 of the traveling trolley 12 in the non-working state), so as to avoid the leveling actuator 13 rotating from the side close to the first winch 141. Specifically, as Figure 3As shown in the figure, the leveling actuator 13 includes a chute pipe 131, a leveling head 132, and a lifting assembly 133. The chute pipe 131 is passed through the traveling trolley 12 and can be lifted relative to the traveling trolley 12. The leveling head 132 is connected to the bottom of the chute pipe 131. The lifting assembly 133 includes a second hoist 1331 fixedly installed on the traveling trolley 12 and a lifting rope 1332 connected between the chute pipe 131 and the second hoist 1331. Since the leveling head 132 is installed at the bottom of the chute pipe 131, by retracting and releasing the lifting rope 1332 with the second hoist 1331 to make the traveling trolley 12 located in the middle of the chute pipe 131, it can ensure that the weight of the part of the leveling actuator 13 below the traveling trolley 12 in the working state is greater than the weight of the part of the leveling actuator 13 above the traveling trolley 12.

[0059] Further, a limiting component 113 is detachably connected to each track beam 111 corresponding to the flipping position, such as Figures 4-7 As shown in the figure, when the traveling trolley 12 flips at the first flipping position, the limiting component 113 provided at the first flipping position is used to limit a trolley track wheel 121 at the first flipping position; as Figures 10-13 As shown in the figure, when the traveling trolley 12 flips at the second flipping position, the limiting component 113 provided at the first flipping position is used to limit the reaction frame track wheel 1442 at the first flipping position, and the limiting component 113 provided at the second flipping position is used to limit a trolley track wheel 121 at the second flipping position. By setting the limiting component 113 to limit the position of a trolley track wheel 121, the traveling trolley 12 can be limited at the first flipping position or the second flipping position. At the same time, when the traveling trolley 12 flips at the second flipping position, the limiting component 113 at the first flipping position is used to limit the reaction frame track wheel 1442, and there is no need to additionally set other limiting structures for limiting the position of the reaction frame 144.

[0060] Specifically, in this embodiment, as Figure 5 As shown in the figure, the limiting component 113 includes a pair of limiting rods 1131 arranged in pairs; when limiting the position of the trolley track wheel 121, the pair of limiting rods 1131 are respectively located on both sides of the trolley track wheel 121 and are respectively abutted against both sides of the trolley track wheel 121; as Figure 12 As shown in the figure, when limiting the position of the reaction frame track wheel 1442, the pair of limiting rods 1131 are respectively located on both sides of the reaction frame track wheel 1442 and are respectively abutted against both sides of the reaction frame track wheel 1442. Using the pair of limiting rods 1131 arranged in pairs as the limiting component 113, by limiting the trolley track wheel 121 or the reaction frame track wheel 1442 between the two limiting rods 1131, the position of the traveling trolley 12 or the reaction frame 144 can be limited, and the structure is simple and easy to operate.

[0061] To improve the stability of the traveling trolley 12 moving along the traveling crane 11, such as Figure 5and Figure 7 As shown in Figure 7 , there are two trolley track wheels 121 connected to each track 1111. At the position corresponding to the flipping position of each track beam 111, a notch a is also provided for another trolley track wheel 121 to flip out of the track 1111. The notch a is located above the track 1111 and communicates with the track 1111. Each side of the walking trolley 12 is connected to the track 1111 of the track beam 111 of the walking carriage 11 through two trolley track wheels 121, which can ensure the stability of the walking trolley 12 moving along the walking carriage 11. At the same time, when one trolley track wheel 121 is restricted at the flipping position by the limit component 113, by setting the notch a, the other trolley track wheel 121 can flip out of the track 1111 when the walking trolley 12 flips. Thus, on the premise of ensuring the stability of the walking trolley 12 moving along the walking carriage 11, the flipping of the walking trolley 12 is realized, and the flipping structure is simple. Similarly, as Figure 2 shown in Figure 2 , at the second flipping position, a limit component 113 and a notch a are also provided to realize the same flipping method.

[0062] Furthermore, as Figure 5 shown in Figure 5 , a cover plate 114 for opening or covering the notch a is provided at the notch a, and the cover plate 114 is detachably connected to the notch a. By providing the cover plate 114, the notch a can be opened when the walking trolley 12 needs to flip, and during the process of the walking trolley 12 moving along the walking carriage 11, the notch a is covered by the cover plate 114 to keep the top of the track 1111 closed and prevent sundries from falling into the track 1111, affecting the movement of the walking trolley 12.

[0063] In addition, it should also be noted that, as Figure 4 shown in Figure 4 , a carriage track wheel 112 for driving the walking carriage 11 to move relative to the hull 2 is provided at the bottom of the walking carriage 11.

[0064] As Figure 14 shown in Figure 14 , based on the above-mentioned flipping type leveling device 1, the present invention also provides a leveling ship, which includes a hull 2. A moonpool is provided on the hull 2, and the above-mentioned flipping type leveling device 1 is installed on the moonpool. This leveling ship realizes the leveling construction of the foundation bed under the surrounding area of the moonpool and the leveling construction of a small area of the foundation bed outside the surrounding area of the moonpool, improves the leveling efficiency of the leveling ship, broadens the application range of the leveling ship, and its driving mechanism 14 has a simple structure and low cost.

[0065] In addition, the present invention also provides a leveling construction method for a leveling ship, including the leveling construction of the foundation bed within the surrounding area of the moonpool and the leveling construction of the foundation bed outside the surrounding area of the moonpool;

[0066] The construction steps for leveling the bed within the surrounding area of the moon pool are as follows: The traveling trolley 12 drives the leveling actuator 13 in a non-working state to move to the first flipping position, and connects one end of the towing rope 143 far from the first winch 141 to the top of the leveling actuator 13; The first winch 141 releases the towing rope 143. Under the gravitational action of the leveling actuator 13, the leveling actuator 13 drives the traveling trolley 12 to flip relative to the traveling carriage 11 in the vertical plane at the first flipping position until the leveling actuator 13 becomes vertical and enters the working state; By moving the traveling carriage 11 longitudinally relative to the hull 2 and the traveling trolley 12 moving along the traveling carriage 11, the working position of the leveling actuator 13 is adjusted to level the bed within the surrounding area of the moon pool; After the leveling operation, the first winch 141 winds up the towing rope 143. Under the pulling force of the towing rope 143, the leveling actuator 13 drives the traveling trolley 12 to flip relative to the traveling carriage 11 in the vertical plane until the leveling actuator 13 flips above the moon pool and enters the non-working state.

[0067] The construction steps for leveling the bed outside the surrounding area of the moon pool are as follows: One end of the towing rope 143 far from the first winch 141 is wound around the towing wheel 142 and connected to the side of the traveling trolley 12 away from the first winch 141. The first winch 141 winds up the towing rope 143 to pull the traveling trolley 12 to drive the leveling actuator 13 in a non-working state to move along the traveling carriage 11 to the second flipping position, and connects one end of the towing rope 143 far from the first winch 141 to the top of the leveling actuator 13; The first winch 141 releases the towing rope 143. Under the gravitational action of the leveling actuator 13, the leveling actuator 13 drives the traveling trolley 12 to flip relative to the traveling carriage 11 in the vertical plane at the second flipping position until the leveling actuator 13 becomes vertical and enters the working state; By moving the traveling carriage 11 longitudinally relative to the hull 2, the working position of the leveling actuator 13 is adjusted to level the bed outside the surrounding area of the moon pool; After the leveling operation, the first winch 141 winds up the towing rope 143. Under the pulling force of the towing rope 143, the leveling actuator 13 drives the traveling trolley 12 to flip relative to the traveling carriage 11 in the vertical plane until the leveling actuator 13 flips above the moon pool and enters the non-working state.

[0068] For the leveling construction method of the above leveling barge, by controlling the movement and flipping of the leveling actuator 13 between the first flipping position and the second flipping position of the traveling carriage 11, the leveling construction of the bed below the surrounding area of the moon pool and a small area of the bed outside the surrounding area of the moon pool is realized, with high leveling efficiency and a wide leveling range.

[0069] In the leveling construction method of the above leveling barge, it should be noted that in the leveling construction steps of the bed within the surrounding area of the moon pool, it also includes restricting the reaction frame 144 near the first winch 141; when connecting the towing rope 143 to the top of the leveling actuator 13, making the towing rope 143 pass under the reaction frame 144; when the leveling actuator 13 flips, the reaction frame 144 exerts a downward force on the towing rope 143. By applying a reaction force to the towing rope 143 through the reaction frame 144, the force required for the first winch 141 to pull the leveling actuator 13 to flip can be reduced.

[0070] In the leveling construction method of the above leveling barge, it should be noted that in the leveling construction steps of the bed outside the surrounding area of the moon pool, before connecting the towing rope 143 to the trolley 12, it also includes connecting the reaction frame 144 to the leveling actuator 13 through the locking steel wire rope 145; when the first winch 141 winds up the towing rope 143 to pull the trolley 12 to move to the second flipping position, the leveling actuator 13 pulls the reaction frame 144 to move to the first flipping position through the locking steel wire rope 145; after the reaction frame 144 moves to the first flipping position, restricting the reaction frame 144 at the first flipping position; when connecting the towing rope 143 to the top of the leveling actuator 13, making the towing rope 143 pass under the reaction frame 144; when the leveling actuator 13 flips, the reaction frame 144 exerts a downward force on the towing rope 143. By applying a reaction force to the towing rope 143 through the reaction frame 144, the force required for the first winch 141 to pull the leveling actuator 13 to flip can be reduced; moreover, by restricting the reaction frame 144 at the first flipping position, a more appropriate angle can be formed between the parts of the flipping towing rope 143 on both sides of the reaction frame 144 to achieve a more labor-saving state.

[0071] In the leveling construction method of the above leveling ship, it should be noted that when the leveling actuator 13 flips to the first flipping position, it further includes restricting one trolley track wheel 121 of the traveling trolley 12 to the first flipping position through the limiting component 113 arranged at the first flipping position, and making the other trolley track wheel 121 of the traveling trolley 12 located below the notch a arranged at the first flipping position. The leveling actuator 13 and the traveling trolley 12 flip relative to the traveling gantry 11 with the axle of the restricted trolley track wheel 121 as the axis, and the unrestricted trolley track wheel 121 flips out of the track 1111 through the notch a above it; when the leveling actuator 13 flips to the second flipping position, it further includes restricting the reaction frame track wheel 1442 of the reaction frame 144 to the first flipping position through the limiting component 113 arranged at the first flipping position, restricting one trolley track wheel 121 of the traveling trolley 12 to the second flipping position through the limiting component 113 arranged at the second flipping position, and making the other trolley track wheel 121 of the traveling trolley 12 located below the notch a arranged at the second flipping position. The leveling actuator 13 and the traveling trolley 12 flip relative to the traveling gantry 11 with the axle of the restricted trolley track wheel 121 as the axis, and the unrestricted trolley track wheel 121 flips out of the track 1111 through the notch a above it. In this embodiment, by restricting one trolley track wheel 121 and making the other trolley track wheel 121 flip out of the notch a opened in the track beam 111, the flipping of the traveling trolley 12 is realized on the premise of ensuring the stability of the traveling trolley 12 moving along the traveling gantry 11. Moreover, when the traveling trolley 12 flips to the second flipping position, the limiting component 113 at the first flipping position is used to limit the reaction frame track wheel 1442, and there is no need to additionally set other limiting structures for restricting the position of the reaction frame 144.

[0074] 2. For the flipping type leveling device 1 provided by the present invention, through a set of driving mechanism 14 to drive the flipping of the leveling actuator 13 and the rapid movement of the leveling actuator 13 between two flipping positions, the manufacturing cost and construction cost are greatly reduced;
