[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] like Figure 1 , Figure 2As shown, this utility model provides an integral segmented assembly structure for a mobile ship section, including two guide rail mechanisms 1. Two mobile platform mechanisms 2 are mounted on the top of the two guide rail mechanisms 1. Positioning mechanisms 3 are mounted on the opposite sides of the two mobile platform mechanisms 2. Several supporting and adjusting mechanisms 4 are arranged in a rectangular array on the top of each of the two mobile platform mechanisms 2. Each mobile platform mechanism 2 includes a mobile docking base 21. Several sliding mechanisms 22 are mounted on the left and right sides of the bottom of each of the two mobile docking bases 21. A snap-fit plate 23 is fixedly installed on the side of the top of each of the two mobile docking bases 21 that is close to each other. A slot 2 penetrating through the top of each of the two snap-fit plates 23 is opened on the left side of each snap-fit plate 23. 4. The inner side of the slot 24 is engaged with a limit baffle 25. The left side of each of the two movable docking bases 21 is fixedly installed with a movable handle 26. Each of the two positioning mechanisms 3 includes an extension plate 31. The two extension plates 31 are fixedly installed on opposite sides of the two movable docking bases 21. The top of each of the two extension plates 31 is fixedly installed with a hydraulic cylinder 32. The output ends of the two hydraulic cylinders 32 pass through to the bottom of the two extension plates 31 and are fixedly installed with a stabilizing metal plate 33. The two stabilizing metal plates 33 are located between the two guide rail mechanisms 1. The top of each of the two stabilizing metal plates 33 is fixedly installed with a limit slide rod 34. The two extension plates 31 are slidably connected to the two limit slide rods 34 respectively.
[0023] In use, the sections of the vessel to be docked are lifted by a gantry crane and placed on several support and adjustment mechanisms 4 on top of two mobile docking bases 21. At the same time, the gantry crane is not completely unloaded, maintaining its connection with the sections of the vessel. The opposing surfaces of the two docking sections of the vessel can stop against the limiting baffles 25. Then, the two mobile docking bases 21 can be pulled together by the moving handles 26. The sliding mechanism 22 slides on the guide rail mechanism 1 to bring the two mobile docking bases 21 together. After they are brought together, the limiting baffles 25 that are engaged in the slots 24 on the top of the two limiting plates 23 can be pulled out to the left, which can facilitate the rapid movement and docking of the two sections of the vessel, improving assembly efficiency. When merging, the hydraulic cylinder 32 can be activated to drive the stabilizing metal plate 33 to descend stably with the sliding connection between the limiting slide rod 34 and the extension plate 31 until it touches the ground, thus preventing the entire mobile docking base 21 from sliding arbitrarily.
[0024] like Figure 3As shown, both guide rail mechanisms 1 include guide rail plates 11, and a vertical guide rail 12 is fixedly installed on the top of the guide rail plates 11. Several sliding mechanisms 22 each include a portal slide plate 221. Two vertical opposite surfaces of the portal slide plate 221 are movably mounted with pulleys 222. The bottoms of the two pulleys 222 are in contact with the top left and right sides of the guide rail plate 11. A pulley groove 223 that runs through the front and back is opened at the bottom of the horizontal part of the portal slide plate 221. A pulley 224 is movably mounted between the left and right sides of the inner wall of the pulley groove 223. The bottom of the pulley 224 is in contact with the top of the vertical guide rail 12.
[0025] When sliding, the sliding mechanism 22 utilizes the contact between the two vertically mounted pulleys 222 and the top left and right sides of the guide rail plate 11, as well as the contact between the pulley 224 in the pulley groove 223 and the top of the vertical guide rail 12, thereby improving the smoothness of movement and making it easier to pull the movable docking base 21.
[0026] like Figure 4 , Figure 5 As shown, each of the several support adjustment mechanisms 4 includes a fixed column 41, which is fixed to the top of two movable docking bases 21. A telescopic sleeve 43 is fitted onto the outer wall of the fixed column 41. Several positioning holes 42 are evenly distributed on the left side of the fixed column 41. A docking hole 44 penetrating the inner cavity of the telescopic sleeve 43 is distributed on the lower left side. The docking hole 44 is aligned with one of the positioning holes 42. A rod 45 is provided on the inner ring of the docking hole 44. The right end of the rod 45 engages with the positioning hole 42 aligned with the docking hole 44. A limiting plate 46 is fixedly installed on the left end of the rod 45. The top of 6 is fixedly connected to an elastic connecting band 47, and the other end of the elastic connecting band 47 is fixedly connected to the left side of the telescopic sleeve 43. The top of the telescopic sleeve 43 is movably installed with a hull contact plate 48, and a rubber pad 49 is fixedly bonded to the top of the hull contact plate 48. A metal spring 411 is fixedly installed at the top of the fixed column 41. The metal spring 411 is made of SUP10 spring steel, with a tensile strength ≥1274MPa and a yield strength ≥1127MPa. It can withstand huge tensile and compressive forces without easily deforming or breaking. The top of the metal spring 411 is fixedly connected to the top of the inner wall of the telescopic sleeve 43.
[0027] When the segmented vessel is placed on several support and adjustment mechanisms 4, it can first contact the hull contact plate 48 included in the support and adjustment mechanism 4. The hull contact plate 48, which is movably installed on the top of the telescopic sleeve 43, can improve the fit. At the same time, the rubber pad 49 can prevent slippage, thereby stably pressing the telescopic sleeve 43 downward, compressing the metal spring 411 on the top of the fixed column 41, until the segmented vessel can no longer be lowered. At this time, the hull contact plates 48 on the top of the telescopic sleeve 43 at different positions will fit according to the shape of the bottom of different segmented vessels, improving applicability. Then, the insertion rod 45 can be inserted into the positioning hole 42 at the corresponding height through the docking hole 44 to complete the limiting of the telescopic sleeve 43, thereby avoiding instability of the segmented vessel after placement. At the same time, the insertion rod 45 can be prevented from being lost by the elastic connecting strip 47 on the left outer wall of the telescopic sleeve 43 connected to the limiting plate 46, making it convenient to reuse the insertion rod 45 next time.
[0028] The working principle of the overall segmented assembly structure of this mobile ship section will be explained in detail below.
[0029] like Figure 1-5As shown, in use, the sections of the vessel to be docked are lifted by a gantry crane and placed on several support and adjustment mechanisms 4 on top of two movable docking bases 21. Simultaneously, the gantry crane is not completely unloaded, maintaining connection with the vessel sections. The opposing surfaces of the two docking vessel sections can stop against the limit baffle 25. Then, the movable handles 26 can be used to pull the two movable docking bases 21 together. The sliding mechanism 22, which slides on the guide rail mechanism 1, allows the two movable docking bases 21 to be brought together. After the two sections of the vessel are brought together, the limiting baffle 25, which is engaged in the top slot 24 of the two limiting plates 23, can be pulled out to the left, which facilitates the rapid movement and docking of the two sections of the vessel, improving assembly efficiency. During the merging process, the hydraulic cylinder 32 can be activated to drive the stabilizing metal plate 33 to descend stably with the sliding connection between the limiting slide rod 34 and the extension plate 31 until it touches the ground, thus preventing the overall moving docking base 21 from sliding arbitrarily. When sliding, the sliding mechanism 22 uses two pulleys 222, which are movably installed on opposite vertical surfaces, and the guide rail plate 1 The contact between the top left and right sides and the contact between the pulley 224 inside the pulley groove 223 and the top of the vertical guide rail 12 improves the smoothness of movement and makes pulling easier. When the segmented ship is placed on several support adjustment mechanisms 4, it can first contact the hull contact plate 48 included in the support adjustment mechanism 4. The hull contact plate 48, which is movably installed on the top of the telescopic sleeve 43, can improve the fit. At the same time, the rubber pad 49 prevents slippage, thereby stably pressing the telescopic sleeve 43 downward and fixing the metal spring 411 on the top of the column 41. The compression continues until the segmented vessel can no longer be lowered. At this point, the hull contact plates 48 on the top of the telescopic sleeves 43 at different positions will fit the shape of the bottom of the different segmented vessels, improving applicability. Then, the insertion rod 45 can be inserted through the docking hole 44 into the positioning hole 42 at the corresponding height to complete the limiting of the telescopic sleeve 43, thereby avoiding instability of the segmented vessel after placement. At the same time, the insertion rod 45 can be prevented from being lost by using the elastic connecting strip 47 on the left outer wall of the telescopic sleeve 43 connected to the limiting plate 46, making it convenient to reuse the insertion rod 45 next time.
[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
