Description

Technical Field

[0001] The utility model relates to the technical field of shipwreck salvage, and in particular to an underwater shipwreck salvage welding eye plate. Background Art

[0002] In the shipwreck salvage industry, to raise a sunken vessel intact from the seabed, the traditional method involves using horizontal directional drilling (HDD) to thread several salvage wires through the vessel's bottom. Two floating barges are then used to simultaneously raise the salvage wires on either side of the vessel to achieve the complete recovery. However, threading salvage wires through the bottom of a sunken vessel is easily affected by sea and geological conditions, making it impractical in certain environmental conditions. Summary of the Invention

The limiting clamping plate is provided on the periphery of the spiral pin, and the limiting clamping plate is fixed with a clamping plate bolt. The limiting clamping plate limits the spiral pin.

[0005] Preferably, the eye plate body comprises an upper panel, a middle panel and a lower panel, the upper panel, the middle panel and the lower panel are supported by webs, and the middle panel is arranged between the upper panel and the lower panel.

[0006] Preferably, the upper panel and the middle panel are of the same length, side sealing plates are provided on the left and right sides of the upper panel and the middle panel, and the upper panel, the middle panel and the side sealing plates form a trapezoidal cube as a whole.

[0007] Preferably, a back plate is provided on the back side of the eye plate body.

[0008] Preferably, annular reinforcement plates are provided around both sides of the inner wall of the mounting hole.

[0009] Preferably, the upper panel, the middle panel and the lower panel are trapezoidal in shape as a whole.

[0010] Preferably, lifting holes are provided at both upper and lower ends of the web.

[0011] The technical solution of the present invention can achieve the following beneficial effects:

[0012] This new welded eye plate for underwater shipwreck salvage is welded to the designated positions on both sides of the ship's hull and then connected to a lifting wire rope for complete shipwreck lifting and salvage. The eye plate has a simple structure, is easily connected to the lifting wire rope, and features a rationally designed force transmission mechanism, offering excellent reliability and applicability.

[0018] The following describes the embodiments with reference to the accompanying drawings to further illustrate the specific implementation of the present invention, such as the shape, structure, relative position and connection relationship between the various components involved, the function and working principle of each part, etc.

[0019] like Figure 1 As shown, the underwater shipwreck salvage welding eye plate includes an eye plate body, a spiral pin 9, a limiting clamping plate 10 and a clamping plate bolt 11. A hollow cavity is provided in the middle part of the upper part of the eye plate body, and a through mounting hole is provided on the hollow cavity. The spiral pin 9 is screwed into the mounting hole, and the limiting clamping plate 10 is provided on the periphery of the spiral pin 9. The clamping plate bolt 11 is used to fix the limiting clamping plate 10, and the limiting clamping plate 10 limits the spiral pin 9.

[0020] The eye plate body includes an upper panel 1 , a middle panel 2 and a lower panel 3 . The upper panel 1 , the middle panel 2 and the lower panel 3 are supported by a web 4 , and the middle panel 2 is arranged between the upper panel 1 and the lower panel 3 .

[0021] The upper and middle panels 1 and 2 are of equal length, with side panels 5 attached to their left and right sides. The upper, middle, and side panels 5 together form a trapezoidal cube. A back panel 6 is located on the back of the eye plate body. Annular reinforcement plates 8 are installed around the inner walls of the cavity mounting hole. The upper, middle, and lower panels 1, 2, and 3 form an overall trapezoidal shape, with lifting holes at the upper and lower ends of the web 4 for rigging the eye plate body.

[0022] The hoisting device places the eye plate in the predetermined position designed for the side plate of the sunken ship. After the hoisting device makes the eye plate fit tightly against the side plate of the sunken ship, the welding robot performs spot welding to fix the eye plate body. After the initial fixation, the hoisting device is separated from the eye plate, and the welding robot continues to complete the further reinforcement welding of the eye plate. Then, the connector of the lifting wire rope is inserted into the internal cavity of the eye plate, and the spiral pin 9 is screwed into the mounting hole of the back plate 6 and inserted into the connector of the lifting wire rope until it is screwed into the bottom. Finally, a limiting card plate 10 is inserted into the upper and lower slots of the spiral pin 9 and fixed with card plate bolts 11 to complete the connection between the eye plate and the lifting wire rope. Annular reinforcement plates 8 are set around the inner wall of the cavity mounting hole on both sides to strengthen the strength of the connection between the spiral pin 9 and the back plate 6.

[0023] This welded eye plate for underwater shipwreck salvage is welded to the designated positions on both sides of the ship's hull. Once connected to the lifting wire rope, it can be used to lift and salvage the entire ship. This eye plate has a simple structure, is easily connected to the lifting wire rope, and features a well-designed force transmission mechanism, ensuring excellent reliability and applicability.

[0024] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
