The present application may be carried out or operated in different embodiments, and various modifications or changes may be made in the details of the application based on different points of view and applications without departing from the spirit of the application.

In the description of the present application, it should be noted that, unless explicitly specified and limited otherwise, the term "connected" should be construed broadly, and for example, it may be a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be. Furthermore, the terms "first" and "second," etc. are used merely to distinguish between descriptions and should not be construed as indicating or implying relative importance.

According to one aspect of the present application, there is provided a ship docking support system and a docking method, which are disposed above a slipway 100 and a buoyancy tank 200, referring to fig. 1 to 3, the support system 400 is used to provide a bottom support for a ship hull 300 having a large appendage 310 at the bottom, and specifically includes a support beam 410, an upper beam support 420 and a lower beam support 430.

The number of the supporting beams 410 may include a plurality of supporting beams 410 disposed at the area of the appendage 310 avoiding the bottom of the hull 300 and surrounding the periphery of the appendage 310, so as to play a role in bearing the weight of the whole hull 300 and reserving space for installing the detection device inside the appendage 310. Further, the bottom of the supporting beam 410 and the bottom of the attachment 310 are kept in the same horizontal plane, which can also reduce the gravity center of the hull 300, thereby reducing the lifting difficulty during the operation of the hull 300 or the slipway 100.

The beam upper support 420 is disposed above the support beam 410, and the top of the beam upper support is abutted against the hull 300 and is adapted to the shape of the sidewall of the hull 300, so as to increase the contact area between the beam upper support 420 and the hull 300, thereby providing lateral support for the hull 300. The number of the beam supports 420 may include a plurality and be symmetrically disposed at both sides of the appendage 310, thereby further increasing the stability of the lateral support of the hull 300.

The under-beam support 430 is disposed below the support beam 410, and the weight for the hull 300 can be transferred to the slipway 100 or the buoyancy tank 200 through the under-beam support 430, with the bottom of the hull 300 spaced apart from the surface of the slipway 100 or the buoyancy tank 200. Wherein the under beam support 430 includes a moving support 432 and a fixed support 431. The fixed support 431 is fixedly connected with the support beam 410 through bolts, so that the hull 300 can be stably supported on the slipway 100 or the buoyancy tank 200. The moving support 432 is also disposed at a predetermined position below the support beam 410 and is spatially offset from the fixed support 431, i.e., can control the lifting and translation of the center of gravity of the hull 300, thereby providing a driving force for the hull 300 to move from the slipway 100 to the predetermined position of the buoyancy tank 200.

In one embodiment, the mobile support 432 includes a track displacement cart having a hydraulic device disposed therein. In the course of moving the hull 300, the rail-shifting cart is set at a preset position on the slipway 100 in advance, the top of the hydraulic device is abutted against the supporting beam 410, and the hydraulic device is controlled to rise, i.e. the supporting beam 410 and the center of gravity of the hull 300 can be raised, and the bottom of the fixed support 431 is separated from the surface of the slipway 100, that is, the movable support 432 in the course of moving the hull will replace the fixed support 431 and become the only support source for supporting the gravity of the hull 300. Correspondingly, after the hull 300 moves to the preset position of the buoyancy tank 200, i.e. during pier falling, the hydraulic device is controlled to descend, i.e. the gravity center of the supporting beam 410 and the hull 300 can be lowered until the bottom of the fixed support 431 is abutted against the surface of the buoyancy tank 200.

Preferably, the support system 400 further includes a moving rail 4321 disposed above the slipway 100 and the buoyancy tank 200, respectively, and the rail-moving cart is capable of sliding on the moving rail 4321. In the course of moving the ship, referring to fig. 5, the moving rails 4321 on the slipway 100 and the buoyancy tank 200 need to be correspondingly connected, so that when the rail-moving trolley is controlled to move, the hull 300 can be controlled to move along the moving rails 4321 in a directional manner, and the hull 300 is moved from the slipway 100 to the preset position of the buoyancy tank 200.

It should be noted that, the rail transit carriage needs to be moved by the moving rail 4321, so before the hull 300 is moved, the fixing support 431 needs to be set at a position avoiding the set position and the moving path of the rail transit carriage, so that the rail transit carriage can move along the moving rail 4321 to a preset position at the bottom of the hull 300. After the ship moving process is finished, the rail-moving trolley moves out of the bottom of the ship body 300 along the moving rail 4321.

Further, in order to avoid the reduction of the supporting performance caused by the removal of the rail-shifting cart, a fixed support 431 may be added to the original position of the rail-shifting cart at the bottom of the hull 300, so as to enhance the supporting performance of the hull 300.

In one embodiment, referring to fig. 2, the support beam 410 includes a plurality of first cross beams 411 spaced apart along a first direction and a plurality of first stringers 412 spaced apart along a second direction, wherein the first direction is a direction along a length of the hull 300, the second direction is a direction along a width of the hull 300, the first stringers 412 are located under the first cross beams 411, and the first cross beams 411 are fixedly connected to increase stability of the support of the hull 300 by the support beam 410 in an attachment area of the hull 310.

Preferably, the plurality of first beams 411 are symmetrically disposed on two sides of the appendage 310 along the second direction, and the plurality of first stringers 412 are also symmetrically disposed on two sides of the appendage 310 along the second direction, that is, the support beams 410 of the appendage 310 on two sides of the appendage 310 along the second direction are symmetrical to each other, and the appendage 310 is used as a space, so that sufficient space is reserved for installing the detection device inside the appendage 310, and meanwhile, the symmetrically disposed support beams 410 can further improve the balance of the support of the hull 300 on two sides of the appendage 310 along the second direction.

Further, the support beam 410 further includes a plurality of second cross members 413 and a plurality of second longitudinal members 414, wherein the second cross members 413 are disposed at intervals along the first direction at the bottom of the hull 300 away from the vicinity of the appendage 310, and the second longitudinal members 414 are used to connect the first cross members 411 with the second cross members 413. That is, the second longitudinal beams 414 and the second cross beams 413 far away from the area of the appendage 310 can connect the supporting beams 410 located at two sides of the appendage 310 along the second direction, so that the bearing capacity of the supporting beams 410 at two sides of the appendage 310 can be further enlarged, and the situation that the structure of the hull 300 is deformed or damaged due to the fact that the gravity of the hull 300 in the area of the drawing is greater than the supporting force of the supporting beams 410 is avoided.

In one embodiment, referring to fig. 3, the beam-on-support 420 includes a support body 421 and a linear side pier 422, where the support body 421 is located between the support beam 410 and the linear side pier 422 to control and adjust the height of the linear side pier 422, so as to adjust the fitting degree of the linear side pier 422 and the hull 300, and the higher the fitting degree of the linear side pier 422 and the hull 300, the better the lateral support stability of the beam-on-support 420 for the hull 300.

Preferably, the support pad 4221 is further disposed between the linear side pier 422 and the hull 300, and the main structure of the linear side pier 422 is mainly made of metal pipe material, and although the linear shape fitting the hull 300 is adopted at the position close to the hull 300, the direct rigid contact between the metal and the hull 300 may cause damage to the surface coating of the hull 300, or even deformation of local area. The wooden support pad 4221 can play a role of buffer contact between the linear side pier 422 and the hull 300, and increase the effective contact area between the linear side pier 422 and the hull 300, so as to prevent the hull 300 from being damaged.

In another aspect, the present application further provides a ship docking method, referring to fig. 3 to 6, including a support system provided by any one of the foregoing embodiments, including the following steps:

step 1), the hull 300 is lifted up by the moving support 432, so that the center of gravity of the hull 300 is raised and completely separated from the slipway 100. Then, the moving support 432 is controlled to move along a predetermined path, so that the hull 300 is moved from the slipway 100 to a predetermined position on the buoyancy tank 200.

Step 2), the movable support 432 is used to control the hull 300 to descend until the top of the movable support 432 is separated from the bottom of the support beam 410, so that the fixed support 431 replaces the movable support 432 to completely support the hull 300, then the movable support 432 is removed, and the fixed support 431 is additionally installed at the position where the movable support 432 is originally arranged, so that the stability of the support system 400 is further increased, and the occurrence of the situation that the hull 300 is damaged due to gravity unbalance caused by the removal of the movable support 432 is avoided.

And 3) injecting water into the dock to enable the buoyancy tank 200 to float under the action of buoyancy, and then moving the hull 300 to the deep water dock area by pulling the buoyancy tank 200.

And 4) draining water to the outside of the dock, allowing the buoyancy tank 200 to sit and sink to the bottom of the deepwater dock and fixing, and then injecting water into the dock again, so that the hull 300 floats under the action of buoyancy until reaching the preset undocking height, and pulling the hull 300 to the outside of the dock.

The present application provides a ship docking support system and a method of launching, the support system including a support beam 410, an upper beam support 420, and a lower beam support 430. The support beam 410 is disposed at the bottom of the hull 300, the beam upper support 420 is disposed above the support beam 410, and is abutted against the outer shell of the hull 300, and the beam lower support 430 is disposed below the support beam 410, for providing support for the hull 300 to be stabilized on the slipway 100 or the buoyancy tank 200, and for providing driving force for the hull 300 to move from the slipway 100 to a predetermined position of the buoyancy tank 200.
