Description

Technical Field

[0001] This utility model provides a seamless docking auxiliary device, belonging to the technical field of deck installation auxiliary equipment, and particularly relates to a seamless docking auxiliary device for shipbuilding decks. Background Technology

[0002] In shipbuilding, deck docking is a critical step, and its quality directly affects the overall performance of the hull. Traditional deck docking usually relies on manual splicing and welding. Workers first roughly position the deck panels, then use welding guns to spot weld them in place, and finally carry out full welding.

[0003] Existing deck docking auxiliary devices typically only possess basic fixing functions and have relatively simple structures, often consisting of simple clamps or support frames. These devices have several shortcomings: they can only provide rough fixing of the deck, lacking the flexibility to adjust the relative position of the decks during docking, thus failing to meet the requirements for high-precision seamless docking; their fixing methods are relatively simplistic, usually relying on bolt tightening, which is unsuitable for irregularly shaped or curved decks, failing to provide a tight fit and easily leading to insecure fixing; furthermore, they lack effective sealing measures, making it difficult to prevent external impurities from entering the deck gaps during welding or use, affecting docking quality and hull performance, and failing to meet the high-precision, high-efficiency, and high-adaptability requirements of modern shipbuilding for seamless deck docking. Utility Model Content

[0004] In order to solve the above problems, this application provides a shipbuilding deck seamless docking auxiliary device, which solves the problem that traditional deck docking methods are not only inefficient in actual operation.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a shipbuilding deck seamless docking auxiliary device, including a deck beam and a longitudinal beam that is vertically and fixedly connected to the deck beam. A track plate corresponding to itself is provided above the longitudinal beam. A connecting structure is slidably connected to the inner side of the track plate. The connecting structure includes a connecting plate that is slidably connected to the track plate. A suction cup is provided inside the connecting plate. A pressing screw penetrating the connecting plate is provided on the suction cup. A connecting screw penetrating itself is provided on one side of the connecting plate.

[0006] Preferably, the track slab has several connecting plates connected inside by T-shaped sliding grooves, and the track slab is a pair of symmetrically distributed frame plates;

[0007] Any two adjacent connecting plates form a group, and the screw of the connecting screw faces the other group of connecting plates.

[0008] Preferably, a limiting plate corresponding to the sliding groove is fixedly connected to the connecting plate, and the connecting screw and the threaded screw are spatially perpendicularly distributed.

[0009] Preferably, a sealing plate is provided between the threaded screw and the suction cup, which corresponds to the internal control of the connecting shell and is sealed to the suction cup.

[0010] Preferably, the track plate is an L-shaped aluminum alloy plate.

[0011] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0012] The device uses deck beams and longitudinal beams to form a vertical frame foundation. Track plates are laid along the top of the longitudinal beams, providing sliding guidance for the connecting structure. Connecting plates are slidably connected to the track plates via T-shaped sliding grooves, allowing for flexible position adjustment along the track. Suction cups are built into the connecting plates, and extrusion screws pass through the connecting plates and connect to the suction cups. Rotating the extrusion screws controls the suction force of the suction cups, thus fixing the deck panels. Connecting screws pass through one side of the connecting plates to adjust the spacing between adjacent connecting plates, achieving a tight fit between the two deck panels. Limiting plates cooperate with the sliding grooves to ensure the stability of the connecting plates during sliding. A sealing plate is placed between the extrusion screws and the suction cups to ensure a tight seal during the adsorption process. The track plates are made of L-shaped aluminum alloy, possessing lightweight and high-strength characteristics, providing stable support and precise position adjustment throughout the docking process, effectively assisting in the seamless docking and installation of the deck panels.

[0023] like Figure 1 and Figure 2 As shown, a seamless deck docking auxiliary device for shipbuilding includes a deck beam 1, a longitudinal beam 2, a track plate 3, a connecting structure 4, a connecting plate 5, a suction cup 6, an extrusion screw 7, and a connecting screw 8. The deck beam 1 is vertically fixed to the longitudinal beam 2. The track plate 3 is positioned above the longitudinal beam 2. The connecting structure 4 is located inside the track plate 3 and includes a connecting plate 5 that is slidably connected to the track plate 3. The connecting plate 5 has a suction cup 6 inside, with an extrusion screw 7 penetrating through it. A connecting screw 8 penetrates one side of the connecting plate 5. The track plate 3 connects several connecting plates 5 via T-shaped sliding grooves 9, forming a pair of symmetrically distributed frame plates. Adjacent connecting plates 5 form a group, with the connecting screw 8 facing the other group of connecting plates 5. A limit plate 10 is mounted on the connecting plate 5, corresponding to the sliding groove 9. The connecting screw 8 and the extrusion screw 7 are spatially perpendicularly distributed. A sealing plate 11 is located between the extrusion screw 7 and the suction cup 6, corresponding to the internal control of the connecting shell 5 and sealingly connected to the suction cup 6. The track plate 3 is an L-shaped aluminum alloy plate.

[0024] In this embodiment, the deck beam 1 and longitudinal beam 2 are vertically fixed, forming a stable foundation frame. A track plate 3 is installed above the longitudinal beam 2, providing sliding guidance for the connecting structure 4. The connecting plate 5 in the connecting structure 4 is slidably connected to the track plate 3 and contains a suction cup 6. The suction force is adjusted by the compression screw 7 to fix the deck. The connecting screw 8 adjusts the spacing of the connecting plates 5 to ensure a tight fit between the deck and the track plate. The T-shaped sliding groove 9 of the track plate 3, in conjunction with the limiting plate 10 of the connecting plate 5, ensures sliding stability. The sealing plate 11 enhances the sealing performance and prevents impurities from entering. The track plate 3 is made of L-shaped aluminum alloy, which is lightweight and high-strength.

[0025] By adjusting the sliding connection plate 5 and fixing it with the suction cup 6, the deck position can be precisely adjusted to meet the requirements of seamless docking, solving the problems of low precision and easy misalignment in traditional manual welding. Secondly, the device is highly adaptable. The vertical spatial distribution of the connecting screw 8 and the extrusion screw 7 allows for multi-directional force application, adapting to decks of different shapes and curvatures, and avoiding insecure fixing. Furthermore, the device effectively prevents impurities. The sealing plate 11 ensures the seal between the suction cup 6 and the extrusion screw 7, preventing impurities from entering the gaps during welding or use, thus improving docking quality. Finally, the L-shaped aluminum alloy track plate 3 of the device combines lightweight and high strength, providing stable support and adapting to the complex shipbuilding environment. Overall, this device significantly improves the efficiency and quality of deck docking, reduces the labor intensity of workers, and meets the high precision, high efficiency, and high adaptability requirements of modern shipbuilding.

[0026] like Figure 3 and Figure 4 As shown, this shipbuilding deck seamless docking auxiliary device uses deck beams 1 and longitudinal beams 2 as its basic frame. The track plate 3 on the longitudinal beam 2 is a key component, working in conjunction with the connecting structure 4 to achieve deck docking. The connecting plate 5 in the connecting structure 4 contains suction cups 6, which are adjusted by extrusion screws 7 and connecting screws 8 to ensure docking accuracy. The T-shaped sliding groove 9 design of the track plate 3, combined with the limiting plate 10 of the connecting plate 5, allows the connecting plate 5 to slide stably within the track plate 3. Furthermore, the vertical spatial distribution of the connecting screws 8 and extrusion screws 7 enhances structural stability. In addition, the sealing plate 11 ensures a tight seal between the suction cups 6 and the extrusion screws 7. The track plate 3 is made of L-shaped aluminum alloy, combining lightweight and high strength characteristics to meet the requirements of the shipbuilding environment.

[0027] In this embodiment, the deck beam 1 and longitudinal beam 2 are typically made of high-strength steel. The deck beam 1 is approximately 300mm wide and 200mm high, and the longitudinal beam 2 is approximately 200mm wide and 300mm high. They are fully welded together to form a stable vertical frame foundation, with a weld length of not less than 100mm to ensure connection strength. The track plate 3 is made of L-shaped aluminum alloy, approximately 150mm wide and 10mm thick. Its T-shaped sliding groove 9 is approximately 20mm wide and 15mm deep, with a length not less than two-thirds of the longitudinal beam 2, to meet the sliding requirements of the connecting plate 5 while ensuring that the track plate 3 itself possesses good strength and rigidity.

[0028] The connecting plate 5 is generally a rectangular steel plate, approximately 8mm thick and 80mm wide. Its length depends on the docking deck area and the length of the track plate 3, typically 300-500mm. The internal suction cup 6 is a vacuum suction cup, commonly the DN series, with a diameter of approximately 60mm and an adsorption force of up to 300N. It is tightly fitted to the connecting plate 5 via a rubber sealing ring, which is approximately 5mm thick to enhance the sealing effect. The extrusion screw 7 is made of high-strength carbon steel, approximately 10mm in diameter, with a pitch of approximately 1.5mm and a length of approximately 80mm. Its connection to the suction cup 6 is threaded, with a thread length of approximately 20mm. The adsorption force of the suction cup 6 can be adjusted by rotating the extrusion screw 7, with an adjustment accuracy of up to 0.5N.

[0029] The connecting screw 8 is also made of high-strength carbon steel, with a diameter of approximately 12mm, a pitch of approximately 1.5mm, and a length of approximately 100mm. It is used to adjust the spacing between adjacent connecting plates 5, with a spacing adjustment range of 0-50mm to accommodate the docking requirements of decks of different thicknesses. It is spatially perpendicular to the extrusion screw 7, and the two apply force from different directions to enhance structural stability. The limiting plate 10 is a long strip steel plate with a thickness of approximately 6mm, a width of approximately 30mm, and the same length as the connecting plate 5. It fits tightly with the sliding groove 9 to ensure that the connecting plate 5 does not shift when sliding within the track plate 3. The sliding friction is controlled at 5-10N to ensure smooth sliding.

[0030] The sealing plate 11 is made of stainless steel with a thickness of approximately 3mm. Its dimensions match the sealing area of ​​the suction cup 6. The sealing layer between the sealing plate 11 and the suction cup 6 and the internal components of the connecting plate 5 is approximately 2mm thick, which effectively prevents air leakage and ensures the normal operation of the suction cup 6. The entire device achieves high-precision seamless docking of the deck through the precise cooperation of its components, meeting the requirements of shipbuilding processes.

[0031] When implementing the existing technical solutions and methods involved in this plan, the installation of deck beam 1 and longitudinal beam 2 requires precise positioning. Typically, a large gantry crane from the shipyard is used to lift deck beam 1 to the designated position. Deck beam 1 can be made of standard H-beams, such as HN300×175×6.5×9, with its length determined by the actual width of the ship's deck. Longitudinal beam 2 uses H-beams or I-beams that match deck beam 1, such as HW250×250×9×14, and is vertically fixed to deck beam 1 using high-strength M24 or M30 bolts. The bolt tightening torque must meet the design value, generally 300-500 N·m, to ensure the stability of the basic frame.

[0032] The track plate 3 is installed using mounting holes on the track plate, typically secured to the longitudinal beam 2 with M16 expansion bolts. During installation, a tight fit between the track plate 3 and the longitudinal beam 2 must be ensured, and the tolerance of the mounting holes must be controlled within ±0.5mm. The T-shaped sliding groove 9 is designed and machined using precision CNC machine tools to ensure dimensional accuracy and surface roughness. The surface roughness Ra value of the groove is no greater than 1.6μm to facilitate smooth sliding of the connecting plate 5.

[0033] During the installation of connecting structure 4, connecting plate 5 is a custom-made high-strength steel plate, typically 8-10mm thick, with its length and width customized according to the actual docking deck dimensions. Suction cup 6 is a commercially available vacuum suction cup, such as the SMC series ZPTSA25-04, with an adsorption force of up to 400N. It is connected to connecting plate 5 using M8 fastening screws to ensure a secure installation. Both extrusion screw 7 and connecting screw 8 are standard machined screws made of tempered steel with a blackened surface to improve corrosion resistance. The thread precision grade is 6g, and they are used with corresponding M10 and M12 nuts. The tightening torque is controlled at 20-30 N·m to ensure the reliability of the threaded connection.

[0034] During operation, the deck is first placed on the base frame formed by the deck beams 1 and 2. The connecting plate 5 is pushed to slide into the T-shaped sliding groove 9 of the track plate 3 to the appropriate position. The suction cup 6 then adheres to the deck, and the suction force of the suction cup 6 is adjusted by rotating the pressing screw 7 to ensure the deck is firmly fixed. Simultaneously, the spacing between adjacent connecting plates 5 is adjusted using the connecting screw 8 to ensure a tight connection between the decks. The sealing layer between the sealing plate 11 and the suction cups 6 and the internal components of the connecting plate 5 uses oil-resistant and heat-resistant silicone rubber sealant, which has good elasticity after curing to ensure a sealing effect and prevent the entry of air or impurities during the connection process, thus ensuring welding quality. The entire device, in operation, combines existing hoisting, positioning, and welding equipment and technologies, such as using a laser tracking positioning system to assist in precise deck positioning and an automated welding robot for efficient welding, forming a complete seamless deck connection solution that effectively improves shipbuilding efficiency and quality.
