(4) continuing to put down the above-water structural part, enabling the guiding rice hopper on the above-water structural part to fall on the guiding column through the guiding rope, positioning the high guiding column in advance, and slowly putting down until the short guiding column is inserted into the short guiding rice hopper;

(5) and the aquatic structure can be accurately matched and positioned in the underwater structure by continuously lowering.

By adopting the technical scheme of the invention, the following beneficial effects can be obtained:

the positioning and guiding device for the large-tonnage steel structure for integrally salvaging the sunken ship has the advantages of simple structure, no systems such as circuit hydraulic pressure and the like, can be directly used underwater and the like, achieves the effects of easy operation, convenient construction, high positioning efficiency, high positioning precision and the like in the application and construction process, and lays a foundation for the continuous construction of subsequent sunken ship salvaging projects.

Detailed Description

The embodiments of the present invention, such as the shapes and structures of the respective members, the mutual positions and connection relationships between the respective portions, the functions and operation principles of the respective portions, will be described in further detail below with reference to the accompanying drawings.

As shown in fig. 2 and 3, the height difference between the high guide post and the low guide post is 200mm, so that the floating structure 1 is conveniently positioned at 1-2 angles in advance and then the rest 2 angles are continuously positioned; the high guide post 3 and the short guide post 5 are welded on the underwater structure 2, and the structural strength needs to be high to prevent deformation caused by collision in the lowering process; high direction rice fill 4 and short direction rice fill 6 weld on structure 1 on water, for big end up's structural style, structure 1 on water transfers the in-process can thick location guide post earlier, then progressively pinpoints in the guide post.

As shown in fig. 4, the sinking vessel has a certain directivity between the above-water structure and the underwater structure, and in order to ensure that the sinking vessel can be positioned on the high guide posts first and then gradually positioned on the low guide posts at each alignment, three high guide posts 3 and five low guide posts 5 are arranged according to the guide post layout shown in fig. 4.

As shown in fig. 5, corresponding to the arrangement diagram of the guide posts in fig. 4, combining the directionality of the above-water structure 1 and the underwater structure 2, two sets of high guide rice hoppers 4 are arranged at one end of the above-water structure 1, and two sets of low guide rice hoppers 6 are arranged at the other end of the above-water structure 1, wherein the high guide posts 3 are larger than the low guide posts 5 in size, and the corresponding high guide rice hoppers 4 are larger than the low guide rice hoppers 6 in size, so that the high guide posts 3 can only correspond to the high guide rice hoppers 4 during lowering.

As shown in fig. 1, before the above-water structure 1 is lowered, a diver needs to connect the guide rope 7 to the underwater structure 2 in advance and pass through the corresponding guide rice hopper of the above-water structure 1, the crane is matched with the above-water structure and gradually and slowly lowered along the guide rope 7 to enter the high guide post 3, and the diver continues to lower until reaching the final position of fig. 6 after confirmation.

The use method of the large-tonnage sunken ship overall salvage medium and large steel structure positioning and guiding device comprises the following steps:

(1) welding a guide column on an underwater structural member which is placed under water in advance, and welding a guide rice bucket on an above-water structural member which needs to be accurately positioned on the underwater structural member;

(2) when the underwater structural part is placed in an underwater stable state, a diver connects the guide rope 7 to the round hole at the end part of the guide column and fixes the guide rope;

(3) the diver penetrates the guide rope 7 into the guide rice bucket of the overwater structural member, the overwater structural member is hoisted and guided to a higher guide column along the guide rope, and the diver confirms that the guide column enters the guide rice bucket underwater;

(4) continuing to put down the above-water structural part, enabling the guiding rice hopper on the above-water structural part to fall on the guiding column through the guiding rope 7, positioning the high guiding column 3 in advance, and slowly putting down until the short guiding column 5 is inserted into the short guiding rice hopper 6;

(5) and the aquatic structure can be accurately matched and positioned in the underwater structure by continuously lowering.

The invention has been described above with reference to the accompanying drawings, it is obvious that the invention is not limited to the specific implementation in the above-described manner, and it is within the scope of the invention to apply the inventive concept and solution to other applications without substantial modification.
