Description

Technical Field

[0001] This application relates to the technical field of welding apparatus, and in particular to a welding apparatus for hull plate seams. Background Technology

[0002] In shipbuilding, the hull is usually constructed in modular sections and then assembled into a complete hull. During the construction process, steel plates are welded to the frame to form a plate frame structure, and then various plate frame structures are combined and welded into a complete hull.

[0003] Currently, when welding the seams of ship hull plates, especially when welding the upper deck, which is the main anti-longitudinal bending part of the hull, the seams of the hull deck are long straight lines. Technicians usually pre-weld multiple mortise plates at even intervals along the seams to ensure that there are no misalignments between the steel plates on both sides of the seam and that the gaps are uniform. This disperses the thermal stress generated by welding to a larger area, avoids local stress concentration, and thus ensures the welding quality. In addition, the rigid fixation of the mortise plates restricts the free deformation of the hull deck during welding, reducing the risk of deformation at the weld. After the weld cools, technicians need to cut and grind the mortise plates.

[0004] Regarding the aforementioned technologies, due to the long total length of hull plate welds, the large amount of welding, and the high cost of using a large quantity of steel plates, cutting and grinding the steel plates can easily damage the surface of the hull deck. In fact, the thermal stress generated during the cutting and grinding process can cause deformation or cracking of the hull deck, and also increase additional processing steps and costs. At the same time, the fixed steel plates can easily obstruct the movement path of the welding torch, reducing the flexibility of the welding torch movement. During welding, technicians need to change the angle of the welding torch to avoid the steel plates, which can easily cause changes in the working angle between the welding torch and the hull deck, resulting in inconsistent heat input to the hull deck, inconsistent weld width and reinforcement height, and reduced mechanical properties and reliability of the weld. Summary of the Invention

[0005] To improve the convenience and efficiency of hull plate assembly and disassembly, ensure the consistency of welding torch movement, and improve the welding quality of hull plate seams, this application provides a hull plate seam welding device.

[0006] The hull plate seam welding device provided in this application adopts the following technical solution:

[0007] A hull plate welding device includes a frame, a welding torch mounted on the frame, and multiple masts movably placed on the frame. The frame is movably placed on the hull deck. The welding torch is inclined toward the hull deck. The multiple masts are movably attached to each other in sequence along the welding direction of the welding torch. Two first electromagnets are provided at the bottom of each mast. The two first electromagnets are arranged opposite each other. The side wall of the first electromagnet away from the mast is movably attached to the top wall of the hull deck and is magnetically connected to the hull deck.

[0008] The frame is equipped with a moving component that drives the frame to move along the seam of the hull, a disassembly and assembly component for moving and storing the hull plate, and an opening and closing component for turning the first electromagnet on and off.

[0009] The opening and closing assembly includes an opening and closing ratchet rotatably disposed within the mounting plate. The ratchet has 2n teeth. n first contacts are evenly embedded in the outer wall of the ratchet. The mounting plate contains a power source and a first wire electrically connected to the power source. Two first electromagnets are connected in series on the first wire. The first wire has a second contact and a spring-shaped third contact. All n first contacts are movably engaged with the second contacts. The third contacts are movably pressed against the outer wall of the ratchet. When one of the first contacts abuts against the third contact, the first wire forms a complete circuit. A drive unit for driving the ratchet to rotate is provided on the frame.

[0010] By adopting the above technical solution, when welding is required, the technician places the frame on the ship's deck, aligns the output end of the welding torch with the seam of the ship's hull, and then moves the frame along the seam of the ship's hull by moving the assembly. At the same time, the assembly disassembles and assembles the mast plates and places them evenly on the ship's deck, so that the side wall of the first electromagnet away from the mast plate is in contact with the ship's deck, and the two first electromagnets are located on both sides of the seam of the ship's hull.

[0011] Simultaneously, the driving component drives the opening and closing ratchet to rotate clockwise by 1 / 2n turns, causing one of the first contacts to rotate until it abuts against the third contact, connecting the second and third contacts. At this point, the first wire forms a complete circuit, energizing the first electromagnet and attracting it to the ship's deck. This achieves the support and fixation of the mast plate on the ship's deck, reducing the risk of deformation at the weld. Furthermore, with the periodic operation of the disassembly and assembly components, multiple mast plates are installed evenly, improving the ease and efficiency of mast plate installation.

[0012] Then, the moving component drives the frame to move in the opposite direction, while the welding torch works to weld the hull plate seams. When the welding torch moves close to the mast plate, the drive component drives the opening and closing ratchet to rotate clockwise by 1 / 2n turns. At this time, the third contact abuts against the outer wall of the opening and closing ratchet and separates from the first contact, breaking the circuit of the first wire and de-energizing the first electromagnet. At the same time, the disassembly and assembly component disassembles the mast plate, separating it from the hull deck, making it less likely for the mast plate to obstruct the movement of the welding torch, ensuring that the welding torch maintains a consistent welding angle and welding speed, and improving the welding quality of the hull plate seams.

[0013] After the welding torch finishes welding the fixed position of the hull plate, the disassembly assembly places the disassembled hull plate back into its original fixed position. At the same time, the drive unit works to install the hull plate, thereby ensuring that the spacing of the hull plates is consistent after welding. This facilitates the dispersion of the heat stress generated by welding to a larger area, avoids local stress concentration, and improves the welding quality of the hull plate joints.

[0014] After the weld cools, the moving component drives the frame to move, and at the same time the disassembly component and the drive component work to remove the hull plates one by one. Through the above solution, the efficiency of hull plate disassembly and assembly is improved, and the welded hull deck is less likely to be damaged during the disassembly and assembly of the hull plates. This reduces the risk of deformation or cracking of the hull deck caused by cutting and grinding the hull plates, and improves the surface quality of the welded hull deck.

[0015] Optionally, a receiving box is slidably mounted on the frame. The disassembly assembly includes a push plate slidably mounted inside the receiving box, a lever plate fixed on the push plate, the lever plate movably protruding from the receiving box, and multiple support plates movably positioned between the push plate and the lever plate. The side walls of the push plate and the support plates that are close to each other, and the side walls of the lever plate and the support plates that are away from the push plate, are movably pressed together. The support plates are movably fitted against the inner wall of the receiving box. The bottom of the receiving box has a discharge port corresponding to the support plates. A connector is slidably mounted on the receiving box. The connector is located directly above the discharge port. When the support plate is fitted against the inner side wall of the receiving box away from the push plate, the corresponding support plate is located directly below the connector. The receiving box is provided with a first power component for driving the connector to move up and down and a second power component for driving the push plate to slide. The frame is provided with a third power component for driving the receiving box to slide and a locking component for fixing the connector and the support plates.

[0016] By adopting the above technical solution, when installing the mast plate, the first power component drives the connector to descend and pushes the mast plate above the discharge port out, so that the first electromagnet is in contact with the ship's deck. At the same time, the third power component drives the receiving box to slide, so that when the frame moves, the relative position between the receiving box and the ship's deck remains constant, which facilitates the installation of the mast plate. At the same time, the driving component works to energize the first electromagnet, thereby realizing the fixed installation of the mast plate.

[0017] Then the first and third power components work to move the connector and the receiving box to the initial position. At this time, the second power component drives the push plate to slide towards the discharge port, so that the push plate presses against and drives multiple horse plates to move until the horse plates away from the push plate are in contact with the side walls of the receiving box. At this time, the horse plates away from the push plate are directly above the discharge port. Then the first, second and third power components periodically repeat the above steps to realize the automated fixed installation of multiple horse plates.

[0018] When the mast is removed, the first power component drives the connector to descend and fixes the connector to the mast through the locking component. At the same time, the drive component works to de-energize the first electromagnet, and then the first power component drives the connector and the mast to rise.

[0019] If the welding plate is removed during welding, the first power component drives the connector to descend and fixes the connector to the welding plate through the locking component. At the same time, the drive component works to de-energize the first electromagnet. Then, the first power component drives the connector and the welding plate to rise, so that the welding plate rises into the receiving box. At this time, the connector and the welding plate remain relatively fixed. The third power component drives the receiving box to slide, so that the position of the discharge port is on the side where the welding gun has finished welding. Then, the first power component drives the connector to descend and energizes the first electromagnet, realizing the quick assembly and disassembly of the welding plate and making the welding gun's movement less obstructed by the welding plate.

[0020] If the support plate is removed after the weld has cooled, the third power component drives the receiving box to slide, positioning the discharge port on the side away from the welding direction of the welding torch. Then, the first power component drives the connector to descend, and the locking device secures the connector to the support plate. Simultaneously, the drive component operates, de-energizing the first electromagnet. The first power component then drives the connector and support plate to rise until the support plate is inside the receiving box. At this point, the support plate is in contact with the inner top wall of the receiving box, making it difficult for the support plate to rise further. The first power component then continues to rise, separating the connector from the support plate until the connector reaches its initial position. The second power component then drives the push plate to slide, causing the deflector plate to press against and move the support plate towards the push plate, offsetting it from the discharge port. This achieves automated removal and storage of the support plate without the need for cutting or grinding, reducing the cost of support plate removal.

[0021] Optionally, the driving component includes a driving column coaxially rotatably disposed on the connector. The mounting plate has a plug hole for the driving column to be movably inserted. A guide groove is provided on the inner sidewall of the plug hole. The guide groove includes a first guide groove and a second guide groove that are connected. The first guide groove is spirally arranged along the inner peripheral wall of the plug hole, and the second guide groove is arranged along the movement direction of the connector. Both the first guide groove and the second guide groove are open near the inner sidewall of the connector. The driving column has a hemispherical protrusion that is movably located in the guide groove and movably abuts against the inner sidewall of the guide groove. The connector is provided with a limiting structure for limiting the rotation angle of the driving column, an elastic element for rotating the driving column, and a synchronizing element for rotating the driving column and the opening / closing ratchet synchronously.

[0022] By adopting the above technical solution, when installing the mast plate, the first power component drives the connector to descend, so that the drive column is inserted into the insertion hole and the protrusion is located in the first guide groove. Since the first guide groove is spirally arranged, and under the action of the elastic component and the limiting structure, the drive column and the connector are not easy to rotate relative to each other. At this time, the protrusion presses against the inner wall of the first guide groove and drives the mast plate to descend until the first electromagnet is in contact with the ship's deck, making it difficult for the mast plate to continue to descend. At this time, the drive column continues to descend against the force of the elastic component and makes the protrusion slide in the first guide groove, thereby realizing the rotation of the drive column. Under the action of the synchronizing component, the opening and closing gear is driven to rotate clockwise, and the first wire forms a complete circuit, realizing the energization of the first electromagnet. At this time, the locking component fixes the connector and the mast plate, and the protrusion slides into the second guide groove.

[0023] Then the first power component drives the connector to rise and causes the protrusion to slide along the second guide groove until the first power component drives the connector to move to the initial position. At this time, the first electromagnet is attracted to the ship's deck and the connector separates from the mast, thus realizing the installation of the mast.

[0024] When the horse plate is removed, the first power component drives the connector to descend, causing the opening and closing gear to rotate clockwise. At this time, the first wire is disconnected, de-energizing the first electromagnet, and the locking component fixes the connector to the horse plate.

[0025] Then, the first power component drives the connector to rise, and the mounting plate rises synchronously until the mounting plate is inside the receiving box. At this time, the mounting plate is in contact with the inner top wall of the receiving box, making it difficult for the mounting plate to rise further. Then the connector continues to rise to the initial position, separating the connector from the mounting plate, which facilitates the removal and storage of the mounting plate. At the same time, the elastic component causes the drive column to rotate, and the rotation angle of the drive column is limited by the limiting structure, so that the drive column rotates to the initial position. At this time, the protrusion corresponds to the opening end of the first guide groove, which facilitates the next installation of the mounting plate.

[0026] The above solution enables the simultaneous loading and unloading of the mounting plate and the switching on and off of the first electromagnet, improving the coordination of equipment operation, ensuring good repeatability of equipment operation, increasing the efficiency of mounting plate assembly and disassembly, and saving power.

[0027] Optionally, the drive column is provided with a synchronization hole for the ratchet shaft to be movably inserted. The synchronization element includes a synchronization block on the inner peripheral wall of the synchronization hole. The outer peripheral wall of the ratchet shaft is provided with 2n synchronization slots at even intervals for the synchronization block to be movably inserted. The side wall of the synchronization block is movably abutted against the inner side wall of the synchronization slot. The ratchet is provided with a check element that drives the ratchet to rotate in one direction.

[0028] By adopting the above technical solution, when the drive column is inserted into the insertion slot, the shaft of the opening and closing ratchet is inserted into the synchronization hole. At this time, the synchronization block is located in the synchronization groove. When the drive column rotates, the side wall of the synchronization block is pressed against the inner side wall of the synchronization groove, thereby causing the drive column to drive the opening and closing ratchet to rotate until the protrusion slides into the second guide groove. At this time, the drive column drives the opening and closing ratchet to rotate clockwise by 1 / 2n turns, realizing the rotation of the opening and closing ratchet. At the same time, it is convenient to separate the drive column and the opening and closing ratchet, improving the coordination of the assembly and disassembly process of the mast.

[0029] After the ratchet rotates clockwise to its position, the check valve drives the ratchet to rotate counterclockwise. At this time, the third contact can act as a check pawl and mesh with the ratchet, making it difficult for the ratchet to rotate and improving the stability of the first conductor completing the circuit. At the same time, it keeps the protrusion in the second guide groove, which facilitates the separation of the subsequent drive column and the plate.

[0030] Optionally, the locking component includes a second electromagnet located on the side of the drive column away from the connector. A permanent magnet is provided inside the mounting plate. The second electromagnet and the permanent magnet are movably attached to and magnetically connected to each other on their adjacent side walls. A second wire electrically connected to the power supply is provided inside the mounting plate. The second wire is connected in parallel with the first wire. The second electromagnet has two opposing fourth contacts. The second wire has two spring-shaped fifth contacts. The two fourth contacts and the two fifth contacts correspond one-to-one and are movably attached. When the fourth contacts and the fifth contacts are attached, the first wire forms a complete circuit. When energized, the magnetic force of the first electromagnet is greater than that of the second electromagnet.

[0031] By adopting the above technical solution, when the drive column drives the opening and closing ratchet to rotate 1 / 2n revolutions, the drive column descends and rotates, causing the second electromagnet to come into contact with the side wall of the permanent magnet, and driving the second electromagnet to rotate, causing the fourth contact to come into contact with the fifth contact. At this time, the first wire forms a complete circuit, realizing the energization of the second electromagnet and magnetic connection with the permanent magnet, realizing the fixation of the connector head and the mounting plate. Then the first power component drives the connector head to rise.

[0032] If the first electromagnet is energized at this time, its magnetic force is greater than that of the second electromagnet, causing the second electromagnet to separate from the permanent magnet, thus separating the connector from the mounting plate. The connector then continues to rise to its initial position. If the first electromagnet is de-energized, the connector and mounting plate remain fixed, causing the connector to lift the mounting plate until it is inside the receiving box. At this point, the receiving box prevents the mounting plate from rising further, causing the second electromagnet to separate from the permanent magnet. The connector then continues to rise to its initial position, facilitating the next step. This also ensures that the locking / separation of the connector and mounting plate is synchronized during the lifting and lowering of the connector, improving equipment operating efficiency.

[0033] Optionally, the moving component includes rollers rotatably disposed at the four corners of the frame, the outer peripheral walls of the rollers being movably fitted against the ship's deck, a fourth power component being disposed on the frame to drive the four rollers to rotate, a video monitoring module for monitoring the output end of the welding torch being fixed on the welding torch, and a control module being disposed on the frame, wherein the first power component, the second power component, the third power component, the fourth power component, and the video monitoring module are all electrically connected to the control module.

[0034] By adopting the above technical solution, technicians place the frame on the ship's deck, ensuring the rollers are in contact with the deck and the welding torch is facing the seam of the hull. Simultaneously, the video monitoring module monitors the output end of the welding torch and transmits the position data of the welding torch and the seam of the hull to the control module. The control module then controls the fourth power component to operate, driving the four rollers to rotate, thereby adjusting the position of the frame and moving the frame along the hull weld seam. This ensures that the output end of the welding torch always corresponds to the weld seam, improving the welding accuracy during subsequent welding.

[0035] Simultaneously, the control module drives the first, second, and third power components to operate, thereby installing the hull plate. At the same time, based on pre-inputted data such as the hull deck thickness and hull plate gap width, the control module controls the frequency of the cyclic operation of the first, second, and third power components to adjust the installation spacing of the hull plate to meet different welding requirements.

[0036] Optionally, two abutment rods are elastically slidably arranged on the frame. The two abutment rods are arranged opposite each other, and one end of the abutment rod protrudes movably from the inner side wall of the discharge port. The protruding end of the abutment rod is arc-shaped and movably abuts against the bottom wall of the horse plate.

[0037] By adopting the above technical solution, the flexible abutment rod is less likely to block the connecting head from driving the plate through the discharge port. At the same time, when the plate is in the receiving box, the arc end of the abutment rod presses against the bottom wall of the plate, so that when the push plate or the deflector plate drives the plate to move, the plate is less likely to slip off from the discharge port.

[0038] Optionally, the frame is provided with two abutting blocks, which are arranged opposite each other. When the first electromagnet is in contact with the ship's deck, the abutting blocks abut against the bottom wall of the deck.

[0039] By adopting the above technical solution, when the first electromagnet is in contact with the ship's deck, the clamping block is pressed against the bottom wall of the mast plate, so that the reaction force applied to the mast plate when the drive column continues to descend acts on the clamping block, making it less likely for the mast plate to squeeze the ship's deck, reducing the risk of deformation caused by stress concentration at the weld, and improving the welding quality.

[0040] Optionally, the side wall of the motor plate is provided with an installation port for removing the power supply, and a cover plate is detachably fixed on the motor plate to movably seal the installation port.

[0041] By adopting the above technical solution, when the mounting plate malfunctions or the power supply is insufficient, causing the mounting plate's support and fixation to fail to meet the usage requirements, technicians can disassemble the cover plate to inspect the mounting plate or replace the power supply, facilitating maintenance of the mounting plate by technicians.

[0042] In summary, this application includes at least one of the following beneficial technical effects:

[0043] 1. The first power component drives the connector and drive column to descend, causing the protrusion to press against the inner wall of the first guide groove. This causes the drive column to press against the mast plate and slide out from the discharge port, and the first electromagnet to fit against the hull deck. At the same time, the protrusion slides in the first guide groove, realizing the rotation of the drive column and the opening and closing ratchet. Due to the interval arrangement of the first contacts, the second and third contacts are intermittently connected. When the opening and closing ratchet rotates, the first wire forms a complete circuit or a broken circuit, realizing the energization and de-energization of the first electromagnet. This allows the connector to periodically rise and fall while fixing or separating the mast plate from the hull deck, improving the convenience and efficiency of mast plate assembly and disassembly, and increasing the reusability. At the same time, when assembling and disassembling the mast plate, it is less likely to affect the welded hull deck, reducing the risk of deformation or cracking of the hull deck caused by cutting and grinding the mast plate, and improving the surface quality of the welded hull deck.

[0044] 2. When dismantling the deck, the first power component drives the connector and drive column to descend, causing the drive column and drive ratchet to rotate. At this time, the first wire is disconnected, and the second wire forms a complete circuit, de-energizing the first electromagnet and energizing the second electromagnet, which magnetically connects with the permanent magnet, thus fixing the connector to the deck. Then, the first power component drives the connector to rise until the deck moves into the receiving box. Then, the second power component drives the push plate and the lever plate to slide, moving the deck into the receiving box and offsetting it from the discharge port, thus achieving automated dismantling and storage of the deck. At the same time, by raising and lowering the connector, the raising and lowering of the deck and the fixing / separation of the deck from the hull deck can be achieved simultaneously, improving the coordination of equipment operation and the repeatability of equipment operation, while improving the dismantling and assembly efficiency of the deck and saving power.

[0045] 3. When welding, the welding torch moves close to the mast plate. At this time, the first electromagnet is energized, and the first power component drives the connector to descend. At this time, the drive component drives the ratchet to rotate, thereby de-energizing the first electromagnet. Simultaneously, the second electromagnet is energized, and the third power component drives the receiving box to slide, thereby maintaining the relative position of the receiving box and the hull deck constant. This facilitates the movement of the drive column into or away from the insertion hole. Then, the first power component connector drives the mast plate to rise until the mast plate no longer obstructs the movement of the welding torch, so that the welding torch maintains a consistent welding angle and welding speed, and improves the welding quality of the hull plate seam.

[0046] Then the third power component drives the receiving box to slide to the side where the discharge port is located after the welding gun has finished welding. Then the first power component drives the connector to complete one descent and rise, thereby fixing the hull plate in its original fixed position. This ensures that the spacing of the hull plates is consistent after welding, which helps to disperse the heat stress generated by welding to a larger area, avoid local stress concentration, and improve the welding quality of the hull plate seams.

Detailed Implementation

[0054] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0055] This application discloses a welding device for ship hull plate seams. (Refer to...) Figure 1 and Figure 2 A hull plate seam welding device includes a frame 1, a welding torch 11 fixed to the bottom of the frame 1, and a receiving box 12 slidably connected to the top of the frame 1. The frame 1 is movably placed on the hull deck 6. The welding torch 11 is located on the left side of the frame 1 and is arranged facing the hull deck 6. The output end of the welding torch 11 extends obliquely in a direction away from the welding direction of the welding torch 11, so that the welding torch 11 is used for right-hand welding. The sliding direction of the receiving box 12 is consistent with the length direction of the frame 1 and parallel to the welding direction of the welding torch 11.

[0056] To drive the frame 1 to move along the hull plate seam 7, a moving component 5 is provided on the frame 1, as shown in the reference. Figure 1 and Figure 2The moving component 5 includes rollers 51 rotatably connected to the four corners of the frame 1. The outer peripheral wall of the rollers 51 is movably fitted with the deck 6 of the ship. The rotation axis of the rollers 51 is consistent with the width direction of the frame 1. The frame 1 is provided with a fourth power component 52 that drives the four rollers 51 to rotate. In this application, the fourth power component 52 is an ultra-thin motor. The welding torch 11 is fixed with a video monitoring module 53 that monitors the output end of the welding torch 11. The frame 1 is fixed with a control module 54. The fourth power component 52 and the video monitoring module 53 are all electrically connected to the control module 54.

[0057] Reference Figure 1 and Figure 2 Multiple mast plates 2 are movably placed inside the housing 12. The multiple mast plates 2 are arranged in sequence along the welding direction of the welding gun 11. Two first electromagnets 21 are fixed at the bottom of the mast plate 2 and arranged opposite each other. The two electromagnets are located on both sides of the hull plate seam 7. The side wall of the first electromagnet 21 away from the mast plate 2 is movably attached to the top wall of the hull deck 6 and is magnetically connected to the hull deck 6. When the first electromagnet 21 is attached to the hull, in order to reduce the risk of the mast plate 2 coming into contact with the weld after welding, the mast plate 2 has an arc-shaped notch at the hull plate seam 7. The frame 1 is equipped with an opening and closing assembly 3 for turning the first electromagnet 21 on and off.

[0058] To facilitate the movement and placement of the mounting plate 2 and improve the efficiency of its assembly and disassembly, the frame 1 is equipped with an assembly and disassembly assembly 4, as shown in the reference. Figure 2 and Figure 3 The assembly 4 includes a push plate 41 slidably connected to the receiving box 12. The sliding direction of the push plate 41 is consistent with the sliding direction of the receiving box 12. A lever 42 is fixed on the push plate 41. Multiple sliding plates 2 are movably located between the push plate 41 and the lever 42. The lever 42 is movably protruding from the receiving box 12. The side walls of the push plate 41 and the sliding plates 2 that are close to each other, and the side walls of the lever 42 and the sliding plates 2 that are away from the push plate 41, are movably pressed together. The sliding plates 2 are movably fitted against the inner wall of the receiving box 12. The bottom of the receiving box 12 has a discharge port 43 corresponding to the sliding plates 2. A connector 44 is movably connected to the receiving box 12. The connector 44 is located at the discharge port. Above the opening 43, when the inner sidewalls of the receiving box 12 of the horse plate 2 are in contact, the corresponding horse plate 2 is located directly below the connector 44. The receiving box 12 is provided with a first power component 45 for driving the connector 44 to rise and fall, and a second power component 46 for driving the push plate 41 to slide. The frame 1 is provided with a third power component 47 for driving the receiving box 12 to slide, and a locking component 48 for fixing the connector 44 and the horse plate 2. The first power component 45, the second power component 46 and the third power component 47 are all electrically connected to the control module 54. In this application, the first power component 45, the second power component 46 and the third power component 47 are all electric push rods.

[0059] When welding is required on the hull plate seam 7, the technician places the frame 1 on the hull deck 6, so that the rollers 51 are in contact with the hull deck 6, and the welding torch 11 is facing the hull plate seam 7. At the same time, the video monitoring module 53 monitors the output end of the welding torch 11 and transmits the position data of the welding torch 11 and the hull plate seam 7 to the control module 54. Then, the control module 54 controls the fourth power component 52 to work, and drives the four rollers 51 to rotate, thereby adjusting the position of the frame 1 and moving the frame 1 along the hull weld seam, so that the output end of the welding torch 11 always corresponds to the weld seam, improving the welding accuracy during subsequent welding.

[0060] Simultaneously, the control module 54 controls the first power component 45 to work, driving the connector 44 to descend, causing the connector 44 to push out the mast plate 2 above the discharge port 43, so that the first electromagnet 21 is in contact with the side wall of the hull deck 6, and the two first electromagnets 21 are respectively located on both sides of the hull plate seam 7. At this time, the control module 54 controls the third power component 47 to work, driving the receiving box 12 to slide, so that when the frame 1 moves, the relative position of the receiving box 12 and the hull deck 6 remains constant. At the same time, the opening and closing component 3 energizes the first electromagnet 21, and causes the first electromagnet 21 to be attracted to the hull deck 6, realizing the support and fixation of the mast plate 2 on the hull deck 6, reducing the risk of deformation at the weld.

[0061] Then, the first power component 45 drives the connector 44 to rise, while the third power component 47 drives the receiving box 12 to slide, so that the connector 44 and the receiving box 12 move to the initial position. Then, the control module 54 controls the second power component 46 to work, driving the push plate 41 to slide towards the discharge port 43, so that the push plate 41 presses against and drives multiple mounting plates 2 to move until the mounting plates 2 away from the push plate 41 are in contact with the side walls of the receiving box 12. At this time, the mounting plates 2 away from the push plate 41 are located directly above the discharge port 43. Then, the first power component 45, the second power component 46, and the third power component 47 periodically repeat the above steps, so as to realize the automated fixed installation of multiple mounting plates 2, improving the installation convenience and efficiency of the mounting plates 2.

[0062] Meanwhile, the control module 54 controls the frequency of the periodic operation of the first power component 45, the second power component 46, and the third power component 47 based on the pre-input data such as the thickness of the hull deck 6 and the width of the hull plate joint 7, thereby adjusting the installation spacing of the mast plate 2 to meet different welding requirements.

[0063] Then, the fourth power component 52 drives the frame 1 to move in the opposite direction, and at the same time, the welding torch 11 works to weld the hull plate seam 7. When the welding torch 11 moves close to the mast plate 2, the first power component 45 drives the connector 44 to descend, and the third power component 47 drives the receiving box 12 to slide until the connector 44 descends to the limit position. At this time, the opening and closing component 3 de-energizes the first electromagnet 21, and the locking component 48 fixes the connector 44 and the mast plate 2. Then, the first power component 45 drives the connector 44 and the mast plate 2 to rise until the mast plate 2 moves into the receiving box 12, so that the mast plate 2 can be disassembled and separated from the hull deck 6. This makes it less likely for the mast plate 2 to obstruct the movement of the welding torch 11, keeps the welding torch 11 consistent in welding angle and welding speed, and improves the welding quality of the hull plate seam 7. At this time, the connector 44 and the mast plate 2 remain relatively fixed.

[0064] Then, the third power component 47 drives the receiving box 12 to slide, so that the position of the discharge port 43 is on the side where the welding gun 11 has been welded. Then, the first power component 45 drives the connector 44 to descend. At this time, the opening and closing component 3 energizes the first electromagnet 21. At this time, the locking component 48 unlocks the connector 44 from the mast plate 2. Then, the first power component 45 drives the connector 44 to rise until the connector 44 rises to the initial position, so as to install the disassembled mast plate 2 in the original fixed position, thereby ensuring that the spacing of the mast plate 2 after welding is consistent, which makes it easier to disperse the heat stress generated by welding to a larger area, avoid local stress concentration, and improve the welding quality of the hull plate seam 7.

[0065] After welding is completed and the weld seam is allowed to cool, the third power component 47 drives the receiving box 12 to slide, positioning the discharge port 43 to the left of the welding torch 11. Then, the fourth power component 52 drives the frame 1 to move, positioning the connector 44 above the mounting plate 2. The first power component 45 drives the connector 44 to descend, and the third power component 47 drives the receiving box 12 to slide. At this time, the opening and closing assembly 3 de-energizes the first electromagnet 21, and the locking component 48 simultaneously secures the connector 44 to the mounting plate 2. Then, the first power component 45 drives the connector 44 and the mounting plate 2 to rise until... The mounting plate 2 is located inside the receiving box 12. At this time, the mounting plate 2 is in contact with the top wall inside the receiving box 12, making it difficult for the mounting plate 2 to continue to rise. Then the connector 44 continues to rise. At this time, the locking member 48 unlocks the connector 44 and the mounting plate 2 until the connector 44 rises to the initial position. Then the second power member 46 drives the push plate 41 to slide, so that the paddle plate 42 is pressed against and drives the mounting plate 2 to move towards the push plate 41 and is offset from the discharge port 43. This realizes the automatic removal and storage of the mounting plate 2 without the need to cut or grind the mounting plate 2, reducing the cost of removing the mounting plate 2.

[0066] Furthermore, to facilitate the switching on and off of the first electromagnet 21 and improve the efficiency of fixing and removing the mounting plate 2, an opening and closing assembly 3 is provided on the frame 1, as shown in the figure. Figure 3 and Figure 4 The opening and closing assembly 3 includes a power supply 32 fixed inside the mounting plate 2 and a first wire 33 electrically connected to the power supply 32. Two first electromagnets 21 are connected in series on the first wire 33. An opening and closing ratchet 31 is rotatably installed inside the mounting plate 2. The rotation axis of the opening and closing ratchet 31 is aligned with the height direction of the frame 1. To facilitate the installation of the opening and closing ratchet 31, an installation groove is provided on the top wall of the mounting plate 2. A fixing block 24 is detachably fixed in the installation groove by bolts. The opening and closing ratchet 31 is rotatably connected to the fixing block 24 and is located between the fixing block 24 and the inner bottom wall of the installation groove. The rotation axis of the opening and closing ratchet 31 passes through the fixing block 24. The number of teeth of the opening and closing ratchet 31 is 2n. In this application, the number of teeth of the ratchet 31 is six, i.e., n is three. In other embodiments, depending on the size of the ratchet 31, the number of teeth of the ratchet 31 can also be four, eight, ten, or more, and the arrangement can be the same as in this application. Three first contacts 34 are evenly embedded on the outer wall of the ratchet 31. The first wire 33 is provided with a second contact 35 and a spring-shaped third contact 36. The three first contacts 34 are all in contact with the second contacts 35. The third contact 36 is in contact with the outer wall of the ratchet 31. When one of the first contacts 34 and the third contact 36 abut against each other, the first wire 33 forms a complete circuit.

[0067] To drive the ratchet 31 to rotate and thus switch the first wire 33 on and off, a drive unit 37 is installed on the frame 1, as shown in the reference. Figure 3 , Figure 4 and Figure 5 The driving component 37 includes a driving column 371 coaxially rotatably connected to the bottom of the connector 44. A sealing block 25 is detachably fixed to the mounting plate 2 by bolts. The sealing block 25 is used to seal the opening end of the mounting groove. The sealing block 25 has a plug hole 372 for the driving column 371 to be inserted. A guide groove is formed on the inner side wall of the plug hole 372. The guide groove includes a first guide groove 373 and a second guide groove 374 that are connected. The first guide groove 373 is spirally arranged along the inner peripheral wall of the plug hole 372, and the second guide groove 374 is arranged along the movement direction of the connector 44. The first guide groove 373 and the second guide groove 374 are close to the connector 44. The inner walls of the drive column 371 are all open. A hemispherical protrusion 375 is fixed on the outer peripheral wall of the drive column 371. The hemispherical protrusion 375 is located in the guide groove and is in contact with the inner wall of the guide groove. In order to improve the stability of the protrusion 375 sliding in the guide groove, there are two protrusions 375 and two guide grooves. The two protrusions 375 correspond one-to-one with the two guide grooves and are evenly distributed along the outer peripheral wall of the drive column 371. The connector 44 is provided with an elastic element 376 that makes the drive column 371 rotate and a limiting structure 39 that limits the rotation angle of the drive column 371. In this application, the elastic element 376 is an elastic torsion spring.

[0068] Reference Figure 5 The limiting structure 39 includes an ear plate 391 fixed to the outer peripheral wall of the drive column 371. The ear plate 391 is located inside the connector 44. A limiting groove 392 for the ear plate 391 to rotate is provided inside the connector 44. The side wall of the ear plate 391 is movably pressed against the inner side wall corresponding to the limiting groove 392. There are two ear plates 391 and two limiting grooves 392. The two ear plates 391 correspond one-to-one with the two limiting grooves 392, and they are evenly spaced along the rotation axis of the drive column 371.

[0069] To ensure that the drive column 371 rotates synchronously with the opening and closing ratchet 31, a synchronizing element 38 is provided on the connector 44, as shown in the figure. Figure 3 , Figure 4 and Figure 5 The drive column 371 is provided with a synchronization hole 382 for the rotating shaft of the opening and closing ratchet 31 to be movably inserted. The synchronization component 38 includes a synchronization block 381 fixed on the inner peripheral wall of the synchronization hole 382. Six synchronization grooves 383 are evenly spaced on the outer peripheral wall of the rotating shaft of the opening and closing ratchet 31 for the synchronization block 381 to be movably inserted. The side wall of the synchronization block 381 is movably pressed against the inner side wall of the synchronization groove 383. The opening and closing ratchet 31 is provided with a check element 384 that drives the opening and closing ratchet 31 to rotate. In this application, the check element 384 is a check torsion spring. In order to facilitate the movable insertion of the synchronization block 381 into the synchronization groove 383, the side wall of the synchronization block 381 near the opening and closing ratchet 31 is sharp.

[0070] When the first power component 45 drives the connector 44 to descend, it drives the drive column 371 to insert into the insertion hole 372 and positions the protrusion 375 within the first guide groove 373. Since the first guide groove 373 is spirally arranged and the elastic component 376 ensures that the side wall of the ear plate 391 abuts against the inner side wall of the limiting groove 392, the drive column 371 and the connector 44 are less likely to rotate relative to each other. At this time, the protrusion 375 abuts against the inner wall of the first guide groove 373 and drives the mast 2 to descend until the first electromagnet 21 is in contact with the hull deck 6. This prevents the horse plate 2 from descending further. At the same time, the shaft of the ratchet 31 is inserted into the synchronization hole 382. At this time, the synchronization block 381 is located in the synchronization groove 383. Then, the drive column 371 continues to descend against the force of the elastic element 376 and makes the protrusion 375 slide in the first guide groove 373, thereby realizing the rotation of the drive column 371. This causes the side wall of the synchronization block 381 to press against the inner side wall of the synchronization groove 383, thereby causing the drive column 371 to drive the ratchet 31 to rotate until the protrusion 375 slides into the second guide groove 374.

[0071] At this time, the drive column 371 drives the ratchet 31 to rotate one-sixth of a turn clockwise. When one of the first contacts 34 rotates to abut against the third contact 36, the second contact 35 is connected to the third contact 36. At this time, the first wire 33 forms a complete circuit, realizing the energization of the first electromagnet 21. When the third contact 36 abuts against the outer wall of the ratchet 31 and separates from the first contact 34, the first wire 33 is disconnected, thereby realizing the de-energization of the first electromagnet 21.

[0072] When the first power component 45 drives the connector 44 to rise, the protrusion 375 slides along the second guide groove 374 until the first power component 45 drives the connector 44 to the initial position. At this time, the protrusion 375 separates from the second guide groove 374, and the drive column 371 separates from the insertion hole 372. Under the action of the elastic component 376, the drive column 371 rotates until the side wall of the ear plate 391 abuts against the inner side wall of the limiting groove 392, so that the drive column 371 rotates to the initial position. At this time, the protrusion 375 corresponds to the opening end of the first guide groove 373, and the synchronizing block 381 corresponds to the synchronizing groove 383, which facilitates the next disassembly and assembly of the mounting plate 2.

[0073] Meanwhile, after the ratchet 31 rotates, the check valve 384 drives the ratchet 31 to rotate counterclockwise. At this time, the third contact 36 can act as a check pawl and mesh with the ratchet 31, making it difficult for the ratchet 31 to rotate, thus improving the stability of the circuit completed by the first conductor 33. At the same time, it keeps the protrusion 375 in the second guide groove 374, which facilitates the subsequent separation of the drive column 371 from the plate 2.

[0074] The above solution enables the drive column 371 to lift and rotate the opening and closing ratchet 31, and facilitates the separation of the drive column 371 and the opening and closing ratchet 31, improving the coordination of the assembly and disassembly process of the mounting plate 2. It also enables the loading and unloading of the mounting plate 2 and the energization and de-energization of the first electromagnet 21 to be carried out simultaneously, improving the coordination of equipment operation and the repeatability of equipment operation. At the same time, it improves the assembly and disassembly efficiency of the mounting plate 2 and saves power.

[0075] Furthermore, in order to achieve coordinated lifting of the mast plate 2 and locking / separating of the mast plate 2 and the connector 44, refer to Figure 3 , Figure 4 and Figure 5The locking component 48 includes a second electromagnet 481 located on the side of the drive column 371 away from the connector 44. A permanent magnet 482 is provided inside the mounting plate 2, located between the fixing block 24 and the sealing block 25. The second electromagnet 481 and the permanent magnet 482 are movably attached to each other on their adjacent side walls and magnetically connected. A second wire 483 electrically connected to the power supply 32 is provided inside the mounting plate 2. The second wire 483 is connected in parallel with the first wire 33. The second electromagnet 481 is provided with two oppositely arranged fourth contacts 484. The second wire 483 is provided with two spring-shaped fifth contacts 485. The two fourth contacts 484 and the two fifth contacts 485 correspond one-to-one and are movably attached. When the fourth contacts 484 and the fifth contacts 485 are attached, the first wire 33 forms a complete circuit. When energized, the magnetic force of the first electromagnet 21 is greater than the magnetic force of the second electromagnet 481.

[0076] When the drive column 371 drives the ratchet 31 to rotate one-sixth of a turn, the drive column 371 descends and rotates, causing the sidewalls of the second electromagnet 481 and the permanent magnet 482 to come into contact with each other, and driving the second electromagnet 481 to rotate, causing the fourth contact 484 and the fifth contact 485 to come into contact. At this time, the first wire 33 forms a complete circuit, realizing the energization of the second electromagnet 481 and magnetic connection with the permanent magnet 482, realizing the fixation of the connector 44 and the mounting plate 2. Then the first power component 45 drives the connector 44 to rise.

[0077] If the first electromagnet 21 is energized at this time, its magnetic force is greater than that of the second electromagnet 481, causing the second electromagnet 481 to separate from the permanent magnet 482, thus separating the connector 44 from the mounting plate 2. The connector 44 then continues to rise to its initial position. If the first electromagnet 21 is de-energized at this time, the connector 44 and the mounting plate 2 remain fixed, causing the connector 44 to drive the mounting plate 2 to rise until the mounting plate 2 is located inside the receiving box 12. At this time, due to the obstruction of the receiving box 12, the mounting plate 2 is not easy to rise further, causing the second electromagnet 481 to separate from the permanent magnet 482. The connector 44 then continues to rise to its initial position, facilitating the next step and achieving synchronous and coordinated locking / separation of the connector 44 and the mounting plate 2 during the lifting and lowering of the connector 44, thereby improving the operating efficiency of the equipment.

[0078] Furthermore, to facilitate the movement and storage of the deck 2 and to prevent the deck 2 from compressing the hull deck 6, refer to... Figure 6Two abutment rods 13 are elastically slidably connected on the frame 1. The sliding direction of the abutment rods 13 is consistent with the width direction of the frame 1. The two abutment rods 13 are arranged opposite each other, and one end of the abutment rod 13 is movably protruding from the inner side wall of the discharge port 43. The protruding end of the abutment rod 13 is arc-shaped and is movably pressed against the bottom wall of the mast plate 2. Two abutment blocks 14 are provided on the frame 1. The two abutment blocks 14 are arranged opposite each other and are located directly below the two abutment rods 13. When the first electromagnet 21 is in contact with the ship deck 6, the abutment block 14 is pressed against the bottom wall of the mast plate 2.

[0079] The flexible abutment rod 13 is less likely to obstruct the connector 44 from driving the pallet 2 through the discharge port 43. At the same time, when the pallet 2 is inside the receiving box 12, because the arc end of the abutment rod 13 presses against the bottom wall of the pallet 2, the pallet 2 is less likely to slip off the discharge port 43 when the push plate 41 or the deflector plate 42 drives the pallet 2 to move, thus improving the stability of moving and storing the pallet 2.

[0080] When the first electromagnet 21 is in contact with the hull deck 6, the clamping block 14 is pressed against the bottom wall of the mast plate 2, so that when the drive column 371 continues to descend, the reaction force applied to the mast plate 2 acts on the clamping block 14, making it less likely for the mast plate 2 to squeeze the hull deck 6, reducing the risk of deformation caused by stress concentration at the weld, and improving the welding quality.

[0081] For easier maintenance of the 2nd panel, please refer to... Figure 6 The side wall of the mounting plate 2 is provided with an installation port 22 for the power supply 32 to be taken out. The mounting plate 2 is detachably fixed with a cover plate 23 to the mounting port 22 by bolts.

[0082] When the motor plate 2 malfunctions or the power supply 32 is insufficient, causing the support and fixation of the motor plate 2 to fail to meet the usage requirements, the technician can remove the cover plate 23 to inspect or replace the power supply 32. At the same time, the technician can easily maintain the motor plate 2 by removing the cover plate.

[0083] The implementation principle of a hull plate seam welding device according to an embodiment of this application is as follows: When welding is required, the technician places the frame 1 on the hull deck 6 and aligns the welding torch 11 with the hull plate seam 7. At the same time, the video monitoring module 53 monitors the output end of the welding torch 11 and transmits the position data of the welding torch 11 and the hull plate seam 7 to the control module 54. Then, the control module 54 controls the fourth power component 52 to work, so as to rotate the roller 51, thereby adjusting the position of the frame 1 and driving the frame 1 to move along the hull weld seam.

[0084] Then, the control module 54 controls the first power component 45 to work, driving the connector 44 and the drive column 371 to descend. At this time, the drive column 371 drives the mast 2 to descend until the first electromagnet 21 is in contact with the hull deck 6. Then, the control module 54 controls the third power component 47 to work, driving the receiving box 12 to slide, so that the receiving box 12 and the hull deck 6 maintain a constant relative position. Then, the drive column 371 continues to descend, and under the action of the protrusion 375 and the guide groove, the synchronous block 381 and the synchronous groove 383, the drive column 371 rotates and drives the opening and closing ratchet 31 to rotate one-sixth of a turn, so that one of the first contacts 34 rotates to the point where the third contact 36 is about to abut, so that the second contact 35 and the third contact 36 are connected. At this time, the first wire 33 completes a complete circuit, realizing the energization of the first electromagnet 21 and its adsorption on the hull deck 6, thus fixing the mast 2.

[0085] Simultaneously, the drive column 371 drives the second electromagnet 481 to descend and rotate, causing the second electromagnet 481 to come into contact with the permanent magnet 482, thus driving the second electromagnet 481 to rotate and causing the fourth contact 484 to come into contact with the fifth contact 485. At this time, the first wire 33 forms a complete circuit, realizing the energization of the second electromagnet 481 and its magnetic connection with the permanent magnet 482, thereby fixing the connector 44 to the mounting plate 2.

[0086] Then the first power component 45 drives the connector 44 and the mounting plate 2 to rise. Since the magnetic force of the first electromagnet 21 is greater than that of the second electromagnet 481, the second electromagnet 481 separates from the permanent magnet 482, thereby causing the connector 44 to rise to the initial position.

[0087] Then the second power component 46 drives the push plate 41 to slide, so that the next horse plate 2 moves to the top of the discharge port 43. Then the first power component 45, the second power component 46 and the third power component 47 repeat the above steps to realize the automated fixed installation of multiple horse plates 2.

[0088] Then, the fourth power component 52 drives the frame 1 to move in the opposite direction, and at the same time, the welding torch 11 works to weld the hull plate seam 7. Simultaneously, when the welding torch 11 moves close to the fixed mast plate 2, the first power component 45 drives the connector 44 to descend, and the third power component 47 drives the receiving box 12 to slide, causing the drive column 371 to drive the opening and closing ratchet 31 to rotate one-sixth of a turn. At this time, the third contact 36 abuts against the outer wall of the opening and closing ratchet 31 and separates from the first contact 34. At this point, the first wire 33 is disconnected, thus realizing the first electromagnet... When the power is cut off at 21, the fourth contact 484 and the fifth contact 485 come into contact. At this time, the first wire 33 forms a complete circuit, which energizes the second electromagnet 481, thereby fixing the connector 44 to the mounting plate 2. Then, the first power component 45 drives the mounting plate 2 to rise, making it difficult for the mounting plate 2 to move with the welding gun 11. Then, the third power component 47 drives the receiving box 12 to slide to the left side of the welding gun 11. Then, the first power component 45 descends and rises to the initial position, thus installing the disassembled mounting plate 2 in the original fixed position.

[0089] After welding is completed, wait for the weld to cool. Then, the fourth power component 52 drives the frame 1 to move, while the third power component 47 drives the receiving box 12 to slide, so that the discharge port 43 is located to the left of the welding gun 11. Then, the first power component 45 drives the connector 44 to descend, while the third power component 47 drives the receiving box 12 to slide, so that the receiving box 12 and the ship deck 6 remain relatively stationary, thereby de-energizing the first electromagnet 21 and energizing the second electromagnet 481, thus fixing the connector 44 to the mast plate 2. Then, the first power component 45 drives the connector 44 to rise, and drives the mast plate 2 to move into the receiving box 12. At this time, due to the obstruction of the receiving box 12, the mast plate 2 is not easy to continue to rise. Then, the first power component drives the connector 44 to rise to the initial position. At this time, the second electromagnet 481 separates from the permanent magnet, and the drive column 371 separates from the insertion hole 372. At the same time, the drive column 371 and the second electromagnet 481 rotate to the initial position under the action of the elastic component 376.

[0090] Then the second power component 46 drives the push plate 41 and the deflector plate 42 to slide, so that the deflector plate 42 presses against and drives the horse plate 2 to move closer to the push plate 41 and offset from the discharge port 43, thereby realizing the storage of the horse plate 2 and realizing the automated disassembly and storage of the horse plate 2.

[0091] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
