[0032] See also Figures 1 to 4An embodiment of the present invention provides a combined leveling device, including a supporting device, a first truss assembly, a second truss assembly, a traction device and a leveling assembly. The supporting device includes a floating body 1 and a hull 2 ​​arranged side by side in the left-right direction, that is, the floating body 1 is located on the side of the hull 2.

When the first transverse truss 31 and the second transverse truss 32 are pushed to move in the left-right direction, the first transverse truss 31 and the second transverse truss 32 can drive the floating body 1 to move in the left-right direction. The second truss assembly includes a first longitudinal truss 41 and a second longitudinal truss 42 arranged side by side in the left-right direction. The first longitudinal truss 41 and the second longitudinal truss 42 are both slidably installed on the first transverse truss 31 and the second transverse truss 32 in the left-right direction.

[0033] The traction device is installed on the hull 2, and the traction device includes a first traction device and a second traction device. The first traction device is used to pull or pull the first transverse truss 31, and the second traction device is used to pull or pull the second transverse truss 32, so that the floating body 1 is close to or away from the hull 2 ​​in the left and right direction. The leveling assembly includes a feed pipe 51 and a crane 52. The crane 52 is movably installed on the first longitudinal truss 41 and the second longitudinal truss 42.

[0034] See also Figure 5 When working, move the combined leveling device to the working area and anchor the hull 2. Figure 1 and Figure 3 The first truss assembly is pulled and released by the traction device, so that the first truss assembly and the floating body 1 move left and right and away from the hull 2. Figure 2 and Figure 4 , and then the feeding pipe 51 is lowered to the bottom of the water by the crane 52, so that the stone 6 can be received by the feeding pipe 51 and discharged to the seabed. After the feeding pipe 51 is driven by the crane 52 to complete the leveling operation of one ridge in the front and rear directions, see Figure 2 , the crane 52 lifts the feeding pipe 51, and then drives the feeding pipe 51 to move to the next ridge leveling operation area by moving the second truss assembly, and the operation is repeated in this way. The combined leveling device of this technical solution uses the first truss assembly to slide the floating body 1 and the hull 2. Figure 3 , the distance between the deployed float 1 and the hull 2 ​​during operation; see Figure 1When not in operation, the floating body 1 and the hull 2 ​​are pulled closer, which is scalable, improves the typhoon prevention capability, facilitates towing and dock mooring, is easy to move, has high working efficiency, and has a simple structure, is easy to maintain, and reduces the cost of use.

The fourth winch 74 is located on the right side of the hull 2 ​​and is connected to the left end of the second transverse truss 32 through a fourth connecting rope. When the first connecting rope is pulled by the first winch 71 and the second connecting rope is pulled by the second winch 72, the first transverse truss 31 moves in the left-right direction away from the hull 2 ​​under the joint action of the first connecting rope and the second connecting rope; at the same time, the third connecting rope is pulled by the third winch 73 and the fourth connecting rope is pulled by the fourth winch 74, so that the second transverse truss 32 moves in the left-right direction away from the hull 2 ​​under the joint action of the third connecting rope and the fourth connecting rope, see Figure 4 When the floating body 1 needs to be retracted to make it close to the hull 2, the first winch 71 pulls the first connecting rope, the second winch 72 pulls the second connecting rope, the third winch 73 pulls the third connecting rope, and the fourth winch 74 pulls the fourth connecting rope, see Figure 2 The first traction device and the second traction device arranged in this manner can improve the balance when the floating body 1 is retracted and deployed, and improve the stability and safety of the overall equipment.

Among them, the first material distributor 83 can be movably arranged on the first stone conveying device 81, and the second material distributor 84 can be movably arranged on the second stone conveying device 82 to adapt to the change of the discharge position of the discharge pipe 51. For example, the first material distributor 83 and the second material distributor 84 can be matched with the mounting frames on both sides of the first stone conveying device 81 and the second stone conveying device 82 by means of matching with guide rail sliders, or can be installed on the first stone conveying device 81 or the second stone conveying device 82 by means of moving with walking wheels.
