Technical Field

[0001] The utility model relates to a flip-up plate device which can be turned flat on a multifunctional laying ship. Background Art

[0002] The multifunctional paving ship, also known as the sinking raft ship, is a special non-self-propelled engineering ship, mainly used in inland and coastal waterway regulation projects. It meets the requirements for the construction of regulation buildings on the riverbed with soft foundations (such as sand, etc.) in waterway regulation, and is mainly used for laying soft rafts. This type of ship combines the construction needs of laying soft rafts for slope protection and bottom protection in the Yangtze River waters, and has the characteristics of high construction efficiency. The paving ship is classified as a first-of-its-kind large-scale hydraulic engineering ship.

[0003] When the existing laying ship flap is not in use, it leans against the bracket and cannot be placed flat on the deck. Since it leans against the bracket, the bracket will occupy a certain operating area, and when the flap is leaning against the side, the laying ship is affected by the side wind, which affects the safety of the ship. The flap cannot be completely laid flat on the deck, which poses a safety hazard to the ship during towing. Therefore, a flat flap device on a multifunctional laying ship is proposed to address the above problems. Utility Model Content

[0015] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-3As shown, a flip-flat device on a multifunctional laying ship includes a davit 1, the lower end of which is connected to the edge of the upper surface of a hull 2; a groove 3 is provided on the hull 2, the side wall of the groove 3 is rotatably connected to a first rotating shaft 4, the lower end of a connecting plate 5 is rotatably connected to the first rotating shaft 4, the upper end of the connecting plate 5 is rotatably connected to a second rotating shaft 6, the other end of the second rotating shaft 6 is rotatably connected to the lower end of a flap 7; the upper end of the flap 7 is connected to a flap turning drive assembly; a limit assembly for limiting the connecting plate 5 is provided on the bottom surface of the groove 3.

[0018] like Figure 1 As shown, the flap turning driving assembly includes a winch 8, a wire rope 9 and a first pulley 10; the first pulley 10 is connected to the upper end of the davit 1; the output end of the winch 8 is connected to the wire rope 9, and the other end of the wire rope 9 is connected to the second pulley 14 at the upper end of the flap 7 after passing through the first pulley 10. The winch 8 is arranged on the inner side of the upper end surface of the hull 2.

[0019] like Figure 2 , 3 As shown, the two sides of the lower end of the connecting plate 5 are respectively provided with bayonet holes 11; the limiting assembly includes an insert block 12 and an insert block seat 13, the insert block seat 13 is connected to the bottom surface of the groove 3, and the insert block 12 is inserted into the insert block seat 13 to limit the rotation of the connecting plate 5. The insert block 12 is adapted to the bayonet hole 11.

[0020] Specifically, when the flap 7 is in operation, the connecting plate 5 is in a horizontal position, and when the flap 7 is flattened, the connecting plate 5 is in a vertical position. To ensure that the connecting plate 5 does not accidentally change between the vertical and horizontal positions, bayonet holes 11 are respectively provided on both sides of the lower end of the connecting plate 5, and an insert block 12 is used for locking, which is easy to use and has a reliable structure.

[0021] Specifically, the length of the flap is generally ≥58m, the flap is heavy and the structure is complex.

[0022] Specifically, the initial state is the operating state, at which the connecting plate 5 is in a horizontal state. The operator takes out the insert 12 from the side, then operates the winch 8 to recover the wire rope 9, and adjusts the flap 7 to the intermediate state (i.e., the state when the distance between the first pulley group 10 of the davit and the second pulley 14 at the end of the flap 7 is the smallest) through the first pulleys 10 on the two davits 1 on both sides of the flap 7 and the second pulley 14 at the end of the flap 7. When the connecting plate 5 moves from the horizontal state to the vertical state, the insert 12 is re-embedded into the insert seat 13 to clamp the other side of the lower end of the connecting plate 5. At this time, since the center of gravity of the flap 7 is located on the inner side of the ship compared to the connecting plate 5, the winch 8 is operated to release the wire rope 9, and the flap 7 can be lowered to the position of the deck of the hull 2. (To adjust the flap 7 from the flattened state to the operating state, a small amount of ballast water needs to be pumped on one side of the ship, causing the ship to tilt 1-2 degrees, so that the flap 7 tilts inwardly).

[0023] The invertible flap device on the multifunctional laying ship is provided with a groove 3 side wall rotatably connected to the first rotating shaft 4, the first rotating shaft 4 is rotatably connected to the lower end of the connecting plate 5, the upper end of the connecting plate 5 is rotatably connected to the second rotating shaft 6, and the other end of the second rotating shaft 6 is rotatably connected to the lower end of the flap 7, thereby changing the connection mode between the flap and the hull, so that the flap 7 can be completely inverted and placed on the deck, especially when towing, the flap 7 can be completely inverted and placed on the deck, thereby improving the safety of the ship; when not in operation, the flap 7 can also be completely inverted and placed on the deck, without being affected by side wind, heel, etc., thereby greatly improving the safety and reliability of the ship. At the same time, the flap 7 has no support frame, does not occupy the area of ​​the laying ship's operating area, expands the laying operation range, and improves the economic benefits of laying.

[0024] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
