Description

Technical Field

[0001] The invention relates to a ship block docking technology, and in particular to a digital self-adaptive shape-preserving frame for a ship block curved surface and a working method thereof. Background Art

[0002] Modern shipbuilding utilizes a block-by-block construction method, whereby the entire ship is divided into several sections. Once each section is constructed, they are welded together in a specific sequence to form the entire ship. After the sections are built, the ship's main section needs to be placed for a period of time, awaiting the completion of other sections before docking. Currently, ship sections are typically placed on steel structure cradles. However, due to the limited load-bearing capacity of the steel plates within each section, they are likely unable to withstand the pressure of their own weight. Therefore, the sole use of these steel structure cradles can lead to deformation of the sections, resulting in significant damage.

[0003] The existing method for placing sections requires using a gantry crane to transport the ship sections to a cradle. Workers then visually inspect and adjust the cradle curve to fit the section's curved surface. Once the section is lowered, placement errors are corrected by adding sleepers and small jacks. This process is time-consuming, inaccurate, and unsafe.

[0004] The existing segment fixing method is only to adjust the segment center of gravity between two adjustable piers without corresponding fixing devices, which poses a safety hazard of tipping over.

[0005] Existing ship section shape-keeping equipment is mainly based on fixed arc-shaped steel frames, which have insufficient adaptability to the curved surface after the ship section is placed. Workers need to manually add sleepers or adjust hydraulic cylinders to adapt to the curved surface of the ship section. This method is inefficient and has poor safety. The Chinese patent application with publication number CN 112676890 A mentions a flexible positioning device for digital manufacturing of aircraft skin parts. It uses the shape positioning unit and the shape behavior unit to complete the clamping tooling for large-area aircraft skins. This device improves the efficiency of the clamping tooling for large components, but its clamping method is only suitable for regular rotational parts such as fuselage barrel sections, and cannot adapt to large and complex curved surface parts such as ship sections. Summary of the Invention

[0006] Purpose of the invention: The purpose of the present invention is to provide a digital adaptive conformal frame and working method for the curved surface of a ship section, which can adapt to ship sections with different curved surfaces.

[0007] Technical solution: The present invention includes a main platform, two rows of main hydraulic columns symmetrically distributed along the center line of the main platform, multiple auxiliary hydraulic columns symmetrically distributed on both sides of the two rows of main hydraulic columns, and multiple electromagnetic suction cups rotatably connected to the top of each main hydraulic column and auxiliary hydraulic column; the main hydraulic columns, auxiliary hydraulic columns, and electromagnetic suction cups are all communicatively connected to an on-site industrial control computer, and the main hydraulic columns and auxiliary hydraulic columns make corresponding actions according to the movement commands received from the on-site industrial control computer, and feed back the stroke information and hydraulic pressure information to the on-site industrial control computer; the electromagnetic suction cups generate suction according to the current signal emitted by the on-site industrial control computer, and feed back the suction signal to the on-site industrial control computer; the on-site industrial control computer is used to control the rising height of multiple main hydraulic columns and auxiliary hydraulic columns to adapt to different curved ship sections, and the electromagnetic suction cups generate suction on the ship sections after being energized.

[0008] Two electric lifting platforms are symmetrically arranged at both ends of the upper surface of the main platform, and a pneumatic clamping device is installed on the inner side of the top of the electric lifting platform. The electric lifting platform and the pneumatic clamping device are communicated with the on-site industrial control computer; the two sets of pneumatic clamping devices work together to clamp the ship section, and the electric lifting platform is used to control the height of the pneumatic clamping device.

[0010] The electric lifting platform includes a motor, a screw module connected to the motor through a gear rack set, a linear slider mounted on the screw module, a pair of guide columns arranged parallel to the sides of the screw module and parallel to each other, and a platform slidably mounted on the pair of guide columns and connected to the linear slider. The electric lifting platform can drive the pneumatic clamping device to perform lifting and lowering movements.

[0011] The main hydraulic column includes a base, a pressure cylinder installed on the upper surface of the base, a second sealing cylinder coaxially arranged above the pressure cylinder, a pair of guide rods parallel to the sides of the second sealing cylinder and parallel to each other, and a load-bearing platform located directly above the second sealing cylinder and with the bottom surface fixedly connected to the guide rods; the guide rod is a telescopic guide rod; when the pressure cylinder supplies air to the second sealing cylinder, it pushes the piston and piston rod in the second sealing cylinder to move upward, and when the piston rod in the second sealing cylinder extends out of the second sealing cylinder, it pushes the load-bearing platform to move upward along the guide rod, thereby supporting the entire section of the ship.

[0012] The electromagnetic suction cup includes a bracket, an iron core installed inside the bracket, a coil wound around one end of the bracket, and a panel sleeved around the outer periphery of the coil. The electromagnetic suction cup can generate suction on the ship section, increase the contact area, increase friction, and improve the stability of the support.

[0013] The electromagnetic sucker is rotatably connected to the main hydraulic column or the auxiliary hydraulic column through a universal coupling. The universal coupling can rotate arbitrarily in the hemispherical space to change the direction of the electromagnetic sucker.

The main and auxiliary hydraulic columns can adjust their heights through the on-site industrial control computer, so as to adapt to the different curved surfaces of the ship sections and support the ship sections.

[0029] The technical solution of the present invention is described in detail below in conjunction with specific implementation methods and the accompanying drawings.

[0030] like Figure 1-6 As shown, the digital adaptive shape-holding frame of the present invention is composed of a main platform 1, a main hydraulic column 2, an auxiliary hydraulic column 3, a universal coupling 4, an electromagnetic chuck 5, an electric lifting platform 6, and a pneumatic clamping device 7. The specific components involved are as follows: main platform 1, main hydraulic column 2, auxiliary hydraulic column 3, universal coupling 4, electromagnetic chuck 5, electric lifting platform 6, pneumatic clamping device 7, flexible plug 8, selection device 9, guide device 10, air pump fixing plate 11, air pump 12, air pressure gauge 13, connecting pipe 14, manual switch 15, gear rack assembly 16, motor 17, screw module 18, linear slider 19, clamping strip 20, platform 21, guide column 22, base 23, air inlet valve 24, fixing sleeve 25, guide rod 26, load-bearing platform 27, second sealing cylinder 28, pressure cylinder 29, iron core 30, coil 31, panel 32, bracket 33, switch 34 and first sealing cylinder 35.

[0031] To ensure stable placement of the ship section and reduce pressure, two rows of main hydraulic columns 2 are symmetrically distributed along the centerline of the main platform 1. In this solution, each row has three main hydraulic columns 2. The number of main hydraulic columns 2 in each row can be adjusted according to actual needs and is not limited to the three in this solution. The two rows of main hydraulic columns 2 form a main hydraulic column array. To prevent the center of gravity of the ship section from being too high, resulting in instability during placement, four auxiliary hydraulic columns 3 are symmetrically distributed on both sides of the main hydraulic column array. The auxiliary hydraulic columns 3 are constructed identically to the main hydraulic columns 2, except that their telescopic travel is greater than that of the main hydraulic columns 2. This provides enhanced protection for the sides of the ship section, preventing the section from tipping over and improving safety during placement.

[0032] In order to prevent the stress area between the conformal frame and the ship section from being too small, resulting in excessive pressure and damaging the steel plate of the ship section, an electromagnetic suction cup 5 is designed to increase the stress area, and to reduce the pressure on the steel plate of the ship section by jointly bearing the stress through multiple groups of hydraulic support columns. Therefore, the top of each main hydraulic column 2 and auxiliary hydraulic column 3 is rotatably connected to an electromagnetic suction cup 5; in this solution, the rotational connection is achieved by installing a universal coupling 4 at the top of each main hydraulic column 2 and auxiliary hydraulic column 3, and the universal coupling 4 can rotate arbitrarily in the hemispherical space. In this solution, the universal coupling 4 is composed of a pair of hinges and sleeves with a relative orientation of 90°, so that the electromagnetic suction cup 5 can rotate arbitrarily, such as Figure 6 As shown, two electric lift platforms 6 are symmetrically arranged at both ends of the upper surface of the main platform 1. Pneumatic clamping devices 7 are installed on the inner sides of the top ends of the electric lift platforms 6. The two sets of pneumatic clamping devices 7 work together to clamp the ship section, protecting it from tipping after placement. The electric lift platforms 6 are used to control the height of the pneumatic clamping devices 7.

[0033] The main hydraulic column 2, auxiliary hydraulic column 3, electromagnetic suction cup 5, electric lifting platform 6, and pneumatic clamping device 7 communicate with the on-site industrial computer via the EtherCAT bus. The main hydraulic column 2 and auxiliary hydraulic column 3 respond to movement commands from the on-site industrial computer and provide feedback on travel and hydraulic pressure information to the on-site industrial computer. The electromagnetic suction cup 5 generates suction based on the current signal from the on-site industrial computer and provides feedback on the suction force. The electric lifting platform 6 raises and lowers based on movement commands from the on-site industrial computer and provides feedback on position information. The pneumatic clamping device 7 receives clamping and releasing signals from the on-site industrial computer and provides feedback on the applied pressure. In this solution, the on-site industrial computer consists of a Xinjie TGC65 touch screen as the host computer and a Xinjie XDH-60 PLC as the slave computer. Commands from the on-site industrial computer are first transmitted to the slave computer, which then interprets these commands as timing signals to directly control the corresponding equipment.

[0034] The on-site industrial computer is used to control the rising height of multiple main hydraulic columns 2 and auxiliary hydraulic columns 3 to adapt to the ship sections with different curved surfaces. After the electromagnetic suction cup 5 is energized, it generates suction on the ship sections.

[0035] like Figure 2 As shown, the pneumatic clamping device 7 comprises a flexible mandrel 8, a rotating device 9, a guide device 10, an air pump mounting plate 11, an air pump 12, a pressure gauge 13, a connecting pipe 14, and a manual switch 15. The rotating device 9 is mounted centrally on the side of the guide device 10. The flexible mandrel 8 is connected to the rotating device 9. The rotating device 9 houses a rotating motor that drives the rotating device 9, allowing it to rotate 360° in both directions according to commands from an on-site industrial control computer. Rotation of the rotating device 9 drives the flexible mandrel 8, thereby changing its direction. A first sealing cylinder 35 is mounted within the guide device 10. The air pump 12 is mounted on the air pump mounting plate 11, with its output connected to the first sealing cylinder 35 via a connecting pipe 14. A pressure gauge 13 is mounted on the air pump 12 to continuously monitor the pressure of the air pump 12. The guide device 10 is retractable. The flexible mandrel 8 is made of rubber to prevent damage to the surface coating of the ship's section. The flexible plug 8 is made of rubber and can reduce the impact force of the pneumatic clamping device 7 without damaging the surface coating of the ship.

[0036] The air pump 12 supplies air to the first sealing cylinder 35 through the connecting pipe 14, pushing the piston and piston rod arranged in the first sealing cylinder 35 to move outward. When the piston rod extends out of the first sealing cylinder 35, it will push the flexible head 8 to move along the guide device 10. The two sets of pneumatic clamping devices 7 work together to clamp the ship section from both sides.

[0037] like Figure 3As shown, the electric lifting platform 6 includes a gear rack set 16, a motor 17, a screw module 18, a linear slider 19, a clamping bar 20, a platform 21, and a guide column 22. The output shaft of the motor 17 is mounted on the inner side of one end of the gear rack set 16, and the end of the screw module 18 is mounted on the inner side of the other end of the gear rack set 16. The screw module 18 is connected to the motor 17 through the gear rack set 16. The linear slider 19 is mounted on the screw module 18. In this embodiment, there are two guide columns 22, which are arranged parallel to the sides of the screw module 18 and are parallel to each other. The platform 21 is slidably mounted on a pair of guide columns 22 and is connected to the linear slider 19. When the motor 17 rotates, the screw module 18 is driven to rotate through the gear rack set 16, so that the linear slider 19 moves in the vertical direction, and the platform 21 moves up and down along the guide columns 22 along with the linear slider 19. In this solution, to accommodate the vessel's contours, the secondary hydraulic ram 3 is larger than the primary hydraulic ram 2. Its maximum pressure capacity is 1.5 times that of the primary ram 2 alone, and its maximum travel is twice that of the primary ram 2. A distance meter is located beneath platform 21 to precisely determine its height. The precise transmission ratio of the gear chain ensures accurate control of the height of the lifting platform 6. Three clips 17 are located on platform 21 to accommodate the pneumatic clamping device 7.

[0038] like Figure 4 As shown, the main hydraulic column 2 includes a base 23, an air inlet valve 24, a fixing sleeve 25, a guide rod 26, a load platform 27, a second sealing cylinder 28, and a pressure cylinder 29. The pressure cylinder 29 is fixedly mounted on the upper surface of the base 23 by bolts, and the second sealing cylinder 28 is coaxially arranged above the pressure cylinder 29. In this solution, each main hydraulic column 2 is equipped with a pair of guide rods 26, which are arranged parallel to the sides of the second sealing cylinder 28 and are parallel to each other. The guide rods 26 are mounted on the upper surface of the base 23 and connected to the pressure cylinder 29 through the fixing sleeve 25, which can enhance the connection firmness of the guide rods 26. The load platform 27 is located directly above the second sealing cylinder 28 and its bottom surface is fixedly connected to the guide rods 26; the guide rods 26 are retractable guide rods. The air inlet valve 24 is arranged on the pressure cylinder 29. When the pressure cylinder 29 delivers air to the second sealing cylinder 28, it pushes the piston and piston rod inside the second sealing cylinder 28 upward. When the piston rod inside the second sealing cylinder 28 extends out of the second sealing cylinder 28, it pushes the load platform 27 upward along the guide rod 26. The main hydraulic column 2 and the auxiliary hydraulic column 3 can freely extend and retract within their travel range, providing a large supporting force and a constant acting force.

[0039] like Figure 5As shown, the electromagnetic chuck 5 comprises an iron core 30, a coil 31, a panel 32, a bracket 33, and a switch 34. The iron core 30 is mounted inside the bracket 33, while the coil 31 is wound around one end of the bracket 33. The panel 32 is sheathed around the outer periphery of the coil 31. The surface of the panel 32 is covered with a rubber film to prevent scratches on the surface coating of the ship section. The switch 34 is connected to the coil 31 and can cut off the circuit of the coil 31. This prevents circuit failures that could prevent the magnetic attraction from being released after the adjustment is complete. Anti-slip grooves are provided on the surface of the electromagnetic chuck 5 to increase the friction between the electromagnetic chuck 5 and the ship section. When the electromagnetic chuck 5 is energized, it generates a strong suction force, preventing the ship section from sliding relative to the conformal frame. When the electromagnetic chuck 5 is attracted to the ship section, the normal of the electromagnetic chuck 5 is perpendicular to the surface of the ship. The surface of the electromagnetic chuck 5 is covered with a replaceable rubber film, a special coating that protects the exterior of the ship section. The suction force of the electromagnetic chuck can be adjusted by varying the intensity of the applied current.

[0040] The ship section adaptive shape-keeping frame device of this solution eliminates the process of manually correcting the ship section posture during the placement of the ship section, reduces the time required for the process, greatly improves the safety of the process, reduces the labor intensity of workers, and improves the efficiency of ship construction, making it safe and reliable.

[0041] This solution utilizes primary and secondary hydraulic columns in conjunction with electromagnetic chucks, controlled automatically by an on-site industrial computer, to securely lift the ship section. This eliminates the need for manual correction of the section's position during placement, reduces coordination during the replacement of the section's retaining frame, reduces the need for specialized tooling for section positioning, and reduces the number of section turnovers. This makes the section retaining frame more adaptable, reduces processing costs, and improves the efficiency of section docking. Furthermore, considering the possibility of a section tipping over, pneumatic clamping devices are installed on both sides of the retaining frame, significantly increasing the safety of the section docking process.

[0042] The present invention also includes a working method for a digital adaptive conformal jig for a curved surface of a ship section. The working method is applied to a digital adaptive conformal jig for a curved surface of a ship section, and includes the following steps:

[0043] Before placing the ship block, the on-site industrial computer calculates the elongation of each main hydraulic column and auxiliary hydraulic column according to the ship block curve to make it conform to the ship block curve, and transmits the elongation signal to the corresponding main hydraulic column and auxiliary hydraulic column;

[0044] After receiving the signal, the main hydraulic column and auxiliary hydraulic column move to the predetermined position and feed back the current position to the on-site industrial computer;

[0045] The ship section is hoisted onto the main hydraulic columns and auxiliary hydraulic columns. All the main hydraulic columns and auxiliary hydraulic columns jointly support the ship section. At the same time, the on-site industrial control computer transmits power signals to multiple electromagnetic suction cups, causing them to absorb the ship section to prevent it from sliding.

[0046] After the ship section is placed, the main hydraulic column and the auxiliary hydraulic column will feedback the force signal to the on-site industrial control computer. After judgment by the on-site industrial control computer, the extension of the main hydraulic column and the auxiliary hydraulic column will be adjusted to ensure that the force on the main hydraulic column and the auxiliary hydraulic column is the same; and after the adjustment is completed, the electric lifting platform is controlled to rise to the appropriate position, and the pneumatic clamping device is started to clamp the ship section to prevent it from tipping over.

[0047] The present invention also includes a device, comprising a memory and a processor, wherein:

[0048] a memory for storing computer programs capable of running on the processor;

[0049] The processor is used to execute the steps of the working method for the digital adaptive conformal jig of the curved surface of a ship section when running the computer program.

[0050] The present invention also includes a computer-readable storage medium having a computer program stored thereon, which, when executed by at least one processor, implements the steps of a working method for a digital adaptive conformal jig for a curved surface of a ship section.
