[0028] Please see Figure 1-10 The present invention provides a technical solution: a linear hull structure for a ship, including a main frame 1, a keel plate 2 welded to the main frame 1, and an outer shell plate 3 welded to the outer surface of the main frame 1.

The auxiliary bolt 41 is located in the inner cavity of the main body frame 1, and the auxiliary bolt 41 has a cavity for accommodating the square short rod 43 and the limiting block 45. The limiting block 45 is also slidably connected to the auxiliary bolt 41, and the cross-sectional area of ​​the limiting block 45 is larger than the cross-sectional area of ​​the square short rod 43. The main body frame 1 has an auxiliary hole for the auxiliary bolt 41 to pass through, and the diameter of the auxiliary hole is larger than the diameter of the end face of the auxiliary bolt 41. The auxiliary bolt 41 can be placed inside the main body frame 1 to avoid the auxiliary bolt 41 being in contact with air for a long time, thereby enhancing the anti-corrosion performance of the auxiliary bolt 41 and further improving the connection effect of the auxiliary bolt 41.

[0030] The transmission assembly 5 includes a drive shaft 55 and a secondary disc shaft 59 rotatably mounted on the main frame 1, a first main bevel gear 57 fixedly mounted on the drive shaft 55, a first secondary bevel gear 58 fixedly mounted on the top surface of the secondary disc shaft 59 and meshing with the first main bevel gear 57, universal joints 54 disposed at both ends of the drive shaft 55, a connecting sleeve 51 and a driven shaft 53 connected to the universal joints 54 at both ends of the drive shaft 55, a square long rod 52 fixedly mounted on the end face of the driven shaft 53 and inserted into the connecting sleeve 51, a reversing shaft 510 rotatably disposed inside the main frame 1, and a drive shaft 52 disposed on the main frame. 1. Pulley assembly 56 in the internal cavity; Pulley assembly 56 bypasses reversing shaft 510 and connects to secondary disc shaft 59 and square short rod 43, and secondary disc shaft 59 and square short rod 43 are connected by transmission through pulley assembly 56. The central axis of square long rod 52 coincides with the central axis of connecting cylinder 51, and square long rod 52 can be inserted into connecting cylinder 51. The universal joint 54 allows connecting cylinder 51 and driven shaft 53 to be folded up before transmission, thereby reducing the space required for transportation of the entire main frame 1 and facilitating its actual operation.

[0031] Auxiliary component 6 includes a cylindrical head 61 fixedly connected to the drive shaft 55, a sliding plate 64 slidably disposed inside the cylindrical head 61, a threaded rod 63 rotatably disposed inside the cylindrical head 61 and threadedly connected to the sliding plate 64, a gear shaft 68 rotatably disposed inside the cylindrical head 61, a transmission gear 67 and a second main bevel gear 69 fixedly mounted at both ends of the gear shaft 68, a second auxiliary bevel gear 610 fixedly mounted on the end face of the threaded rod 63 and meshing with the second main bevel gear 69, a ring gear 66 meshing with the transmission gear 67, a movable ring 62 fixedly mounted on the outer surface of the ring gear 66, and... An auxiliary bearing 65 enables rotational connection between the movable ring 62 and the column head 61. The slide plate 64 has a T-shaped structure design and a total of six slide plates 64. The number of threaded rods 63 is the same as the number of slide plates 64. The six threaded rods 63 are arranged equidistantly on the column head 61 around the central axis of the column head 61. The six threaded rods 63 correspond to the six slide plates 64, and the six slide plates 64 can form a hexagonal insertion hole to facilitate the insertion of a hexagonal wrench, thereby driving the column head 61 to rotate. The movable ring 62 is located outside the column head 61, and the outer surface of the movable ring 62 is provided with anti-slip texture.

[0032] Working principle: The inner layer of the hull structure is formed by welding the main frame 1 and the keel plate 2. The outer shell plate 3 is then wrapped around the outer layer of the main frame 1 and finally welded together to form the outer hull of the ship. When the deck is installed on the hull: a hex wrench is inserted into the cylindrical head 61, driving the cylindrical head 61 to rotate. The drive shaft 55, which is fixedly connected to the cylindrical head 61, rotates synchronously on the main frame 1. The drive shaft 55 is fixed with the first main bevel gear 57, which meshes with the first secondary bevel gear 58. The first secondary bevel gear 58 is fixed to the secondary disc shaft 59. The pulley set 56 passes around two reversing shafts 510 to connect the secondary disc shaft 59 with... The main disc-shaped shafts 44 are connected in a transmission manner. Therefore, when the drive shaft 55 rotates, the two main disc-shaped shafts 44 in a single main frame 1 rotate synchronously inside the main frame 1 under the transmission of the first main bevel gear 57, the first secondary bevel gear 58, the secondary disc-shaped shaft 59, the reversing shaft 510, and the pulley group 56. A square short rod 43 is fixed on the main disc-shaped shaft 44 and is slidably connected to the auxiliary bolt 41. The auxiliary bolt 41 is threadedly connected to the fixing nut 42 fixed in the inner cavity of the main frame 1. Therefore, when the main disc-shaped shaft 44 rotates, the auxiliary bolt 41 on the main frame 1 can be unscrewed from inside the main frame 1 and then screwed into the deck. Inside, the drive shafts 55 on other main frames 1 are connected to universal joints 54 at both ends, and are connected to connecting cylinders 51 and driven shafts 53 through the universal joints 54. A square rod 52, which can be inserted into the connecting cylinder 51, is fixed on the driven shaft 53. Therefore, when the drive shaft 55 on a single main frame 1 rotates, the drive shafts 55 on the other main frames 1 rotate synchronously under the transmission of the universal joints 54, driven shafts 53, square rods 52, and connecting cylinders 51. This drives the auxiliary bolts 41 on multiple main frames 1 to simultaneously unscrew from the main frame 1, and simultaneously screws the multiple auxiliary bolts 41 into the deck to provide the deck with... Assembled on the main frame 1, but when encountering different models of hexagonal wrenches; when it is necessary to adjust the size of the hexagonal socket on the cylindrical head 61: rotate the movable ring 62, which is rotatably connected to the cylindrical head 61 via the auxiliary bearing 65, and fix the ring gear 66, which meshes with the transmission gear 67, on the inner surface of the movable ring 62. The transmission gear 67 is rotatably mounted inside the cylindrical head 61 via the gear shaft 68, and the other end of the gear shaft 68 is fixed to the second main bevel gear 69, which meshes with the second set of bevel gears 610. The second set of bevel gears 610 is also fixed with a threaded rod 63. Therefore, when the movable ring 62 rotates in the cylindrical head 61, refer to Figures 8 to 10The six threaded rods 63 rotate synchronously inside the cylindrical head 61, and the threaded rods 63 are slidably connected to the sliding plate 64 slidably set on the cylindrical head 61. Therefore, when the six threaded rods 63 rotate, the six sliding plate 64 slide synchronously on the cylindrical head 61. Among the six threaded rods 63, the thread helix directions of the two threaded rods 63 with the central axis collinear are opposite to each other. Therefore, the six sliding plate 64 can slide simultaneously in a direction close to or away from the center of the cylindrical head 61, thereby changing the size of the hexagonal socket on the cylindrical head 61 to meet the insertion requirements of different models of hexagonal wrenches.
