[0002] Motherboard refers to the basic flat plate or large plate used in the assembly process. These plates play a supporting or basic structural role in the subsequent assembly process. The motherboard in marine engineering is used in marine engineering and offshore platform construction. There are many different types of structural plates and components used to build stable and durable offshore facilities. Motherboards are required for key structural components used in the construction of offshore platforms, floating production storage and offloading units, semi-submersible drilling platforms, etc. This plate can be the backbone supporting the entire structure, ensuring the stability and strength of the platform. With the rapid advancement of science and technology, marine engineering has also developed rapidly, so the application of motherboards has become more and more common, which requires the processing and production of motherboards. The docking and splicing of motherboards is an important step in the processing of plates.

[0003] At present, the existing process of butt-jointing and splicing the motherboards is easily affected by the operation of the equipment, which results in a large amount of welding slag when the motherboards are welded and spliced, causing the welding slag to accumulate in the gaps of the motherboards that need to be butt-jointed, thereby affecting the accuracy of welding and resulting in low welding quality.

[0026] The present invention provides a device for butting and splicing motherboards in marine engineering groups. It has the following beneficial effects:

[0027] 1. The marine engineering team's motherboard docking and paneling equipment uses a linear drive to move the gantry, which can adjust the overall position of the gantry. At the same time, the rotation of the servo motor output end can drive the lead screw to rotate, and under the sliding guide of the strip slider, the lifter is driven to move in a straight line. At this time, the welding gun is passively driven to move together, thereby increasing the direction of movement of the welding gun, which is conducive to the welding and paneling of the opposing motherboard plate materials.

[0028] 2. The marine engineering team's vertical motherboard docking and splicing equipment uses the contraction and extension of the output end of the lifter to drive the welding gun to move up and down, and then adjust the height of the welding gun to adapt to vertical motherboard materials of different thicknesses. The welding port at the bottom of the welding gun is adjusted to a suitable position away from the vertical motherboard material to be welded, which helps to improve the welding quality.

[0029] 3. The marine engineering team's vertical motherboard docking and splicing equipment uses a V-shaped elastic sheet located at the gap between the two vertical motherboard materials that need to be welded, and the V-shaped elastic sheet is driven to move to the left. At this time, the moving V-shaped elastic sheet will squeeze out the welding slag that falls into the gap between the vertical motherboard materials, making it difficult for the welding to get stuck in the gap between the vertical motherboard materials. The V-shaped elastic sheet is V-shaped, which can separate the welding slag to both sides, which is helpful for subsequent processing.

[0030] 4. The marine engineering team's vertical motherboard docking and splicing equipment uses a crescent block to press the stress rod, and the stress rod drives the zigzag scraper plate to rotate outward to adjust the angle. At this time, the symmetrical zigzag scrapers on both sides rotate together to scrape and push the welding slag at the edge of the vertical motherboard raw material gap to both sides, so that the welding slag can be removed from the vertical motherboard raw material gap, and the welding slag can be processed in time without being easily affected by the welding slag.

[0031] 5. The marine engineering team's motherboard docking and splicing equipment generates suction through an air suction pump, and the air intake hopper can increase the air intake volume, thereby absorbing the harmful gases generated during welding by the welding gun, reducing the diffusion of harmful gases, and through the connection of the right-angle air pipe, the air outlet end of the air suction pump discharges the absorbed harmful gases into the reagent box, and allows the harmful gases to fully contact and react with the harmful gas reaction reagents in the reagent box, thereby timely treating the harmful gases.

[0032] 6. The docking and splicing equipment of the motherboard of the marine engineering team, when connected to the right-angle air pipe, makes the suction pump and the air intake hopper slide to the left together and after reset, the driving force on the air intake hopper disappears, and under the elastic force of the reset spring bar, the suction pump drives the air intake hopper to move in the opposite direction, and then the reciprocating movement of the air intake hopper can increase the suction range of harmful gases.

[0033] 7. The marine engineering team's vertical motherboard docking and splicing equipment uses the extension of the cylinder output end to drive the right-angle connecting plate downward. At this time, under the sliding connection of the pressing guide column, the rolling ball presses the vertical motherboard material. At the same time, the pressing guide column can slide and, under the elastic tension of the cylindrical spring, can perform elastic pressing according to the different thicknesses of the vertical motherboard material.

[0034] 8. The marine engineering team's vertical motherboard docking and splicing equipment uses the inclined surface of the limiting wedge to be pressed. At this time, the symmetrical limiting wedges on both sides move toward each other, which can limit the two vertical motherboard materials that need to be welded, making it less likely for the vertical motherboard materials to be skewed. At the same time, the cylindrical roller can roll in contact with the outer edge of the vertical motherboard material, reducing resistance and facilitating the overall movement of the equipment.

[0047] The first embodiment, as Figure 1-Figure 5 As shown, the present invention provides a technical solution: a device for butting and splicing motherboards of a marine engineering group, comprising:

[0048] The gantry 1 and the linear drive 2, wherein the gantry 1 has a supporting frame, and the side of the top of the gantry 1 is fixedly installed with the output end of the linear drive 2;

[0049] The marine engineering group's motherboard butt-jointing equipment also includes:

[0050] The welding mechanism 3 is used for splicing the plate materials and is installed on the top of the gantry 1;

[0051] Among them, the welding mechanism 3 includes a screw 31 and a servo motor 32, the screw 31 is rotatably installed in the middle of the gantry 1, the servo motor 32 is installed at the side of the gantry 1, and the output end of the servo motor 32 is fixedly installed between the screw 31 through a coupling, and a strip slider 33 is installed on the outer thread of the screw 31, and the strip slider 33 is slidably installed between the top of the gantry 1, and a lifter 34 is fixedly installed on the side of the outer side of the strip slider 33, and a welding gun 35 is fixedly installed on the output end of the lifter 34, and a slag cleaning component 36 is installed on the outer side of the welding gun 35. A mobile trolley is installed under the supporting legs at the bottom of the gantry 1, and the gantry 1 is driven to move by the linear drive 2, so that the overall position of the gantry 1 can be adjusted;

[0052] At the same time, the staff turns on the servo motor 32 to work. The rotation of the output end of the servo motor 32 drives the lead screw 31 to rotate, and under the sliding guide of the bar slider 33, the lifter 34 is driven to move linearly. At this time, the welding gun 35 is passively driven to move together, thereby increasing the direction in which the welding gun 35 can move.

[0053] The lead screw 31 and the servo motor 32 are installed at the same height so that the output end of the servo motor 32 can drive the lead screw 31 to rotate. The slag cleaning assembly 36 is installed below the welding gun 35.

[0054] The staff turns on the lifter 34 to work, and uses the contraction and extension of the output end of the lifter 34 to drive the welding gun 35 to move up and down, and then adjust the height of the welding gun 35 so that the welding port at the bottom of the welding gun 35 is adjusted to a position suitable for the distance from the motherboard material to be welded.

[0055] The slag cleaning component 36 includes an electric telescopic rod 361 and a right-angle guide rod 362. The electric telescopic rod 361 is installed on the side of the outer side of the welding gun 35. The top of the right-angle guide rod 362 is fixedly connected to the outer side of the welding gun 35 and close to the position of the electric telescopic rod 361. The output end of the electric telescopic rod 361 is fixedly installed with a crescent block 363. The bottom end of the right-angle guide rod 362 is rotatably installed with a zigzag scraper plate 364. A V-shaped elastic piece 365 is fixedly installed on the side of the outer side of the zigzag scraper plate 364. A torque spring 366 is fixedly installed between the top of the zigzag scraper plate 364 and the outer side of the right-angle guide rod 362. A force-bearing rod 367 is fixedly installed in the middle of the top of the plate 364. Under the support connection of the lifter 34, when it is driven to the left for welding through the welding gun 35, under the support of the right-angle guide rod 362 and the zigzag scraper plate 364, the V-shaped elastic sheet 365 is located at the gap between the two vertical mother plate raw materials that need to be welded, and the V-shaped elastic sheet 365 is driven to move to the left. At this time, the moving V-shaped elastic sheet 365 will squeeze out the welding slag that falls into the gap of the vertical mother plate raw material, making it difficult for the welding to get stuck in the gap of the vertical mother plate raw material, and the V-shaped elastic sheet 365 is V-shaped, so that the welding slag can be separated to both sides.

[0056] There are two zigzag scraping plates 364, and the two zigzag scraping plates 364 are symmetrically installed along the welding gun 35. The right-angle guide rod 362 passes through the center of the torque spring 366. The staff turns on the electric telescopic rod 361 to work. The output end of the electric telescopic rod 361 is extended to push the crescent block 363 downward. The crescent block 363 contacts the top of the force-bearing rod 367. As the crescent block 363 continues to move downward, and under the rotation support of the right-angle guide rod 362, the force-bearing rod 367 drives the zigzag scraping plates 364 to rotate outward to adjust the angle. When the torque spring 366 is compressed, the symmetrical zigzag scraping plates 364 on both sides rotate together, and the welding slag at the edge of the gap between the raw materials of the vertical mother plate can be scraped and pushed to both sides, so that the welding slag raw materials can be separated from the raw materials of the vertical mother plate, and the welding slag can be processed in time without being easily affected by the welding slag. When the output end of the electric telescopic rod 361 contracts, the pressing force of the crescent block 363 on the top of the force-bearing rod 367 disappears, and under the torque force of the torque spring 366, the zigzag scraping plate 364 rotates in the opposite direction to reset, which helps to scrape the welding slag back and forth in the future.

[0057] The second embodiment, as Figure 1-Figure 7 As shown, based on the first embodiment:

[0058] An air suction mechanism 4 is installed on the outside of the strip slider 33. The air suction mechanism 4 includes a reagent box 41. The outside of the reagent box 41 is fixedly installed on the outside of the strip slider 33, and the reagent box 41 is installed on the end of the strip slider 33 away from the lifter 34. A rectangular hole is opened on the top of the reagent box 41. An air suction pump 42 is slidably installed on the top of the reagent box 41 through the rectangular hole. The air suction end of the air suction pump 42 is connected to a right-angle air pipe 43. The top of the right-angle air pipe 43 is slidably installed on the top of the strip slider 33 through a shaft sleeve. The bottom end of the right-angle air pipe 43 is connected to an air inlet hopper. 44. A reset spring bar 45 is fixedly installed between the top of the reagent box 41 and the outer side of the suction pump 42. The suction pump 42 generates suction, and under the connection of the right-angle air pipe 43, the air intake hopper 44 can increase the air intake volume, thereby absorbing the harmful gas generated by the welding gun 35 during welding, reducing the diffusion of the harmful gas, and through the connection of the right-angle air pipe 43, the air outlet end of the suction pump 42 discharges the absorbed harmful gas into the reagent box 41, and allows the harmful gas to fully contact the harmful gas reaction reagent in the reagent box 41 and react.

[0059] A cover plate 46 is fixed to the outside of the reagent box 41 by screws. The cover plate 46 is installed near the top of the reagent box 41. A control valve 47 is installed at the bottom of the reagent box 41. A rectangular notch 48 is provided on the outside of the air inlet hopper 44. The rectangular notch 48 facilitates the absorption of gas and increases the air intake volume. The rectangular notch 48 is provided near the bottom of the air inlet hopper 44.

[0060] The air outlet of the suction pump 42 passes through the rectangular hole and extends to the interior of the reagent box 41 . There are two reset spring bars 45 , and the two reset spring bars 45 are symmetrically installed along the right-angle air pipe 43 .

[0061] When the zigzag scraper plate 364 is rotated outward to adjust the angle, the welding slag in the gap can be scraped off and an outward pushing force can be applied to the air inlet hopper 44. Under the connection of the right-angle air pipe 43, the air suction pump 42 and the air inlet hopper 44 slide to the left together, and the reset spring bar 45 is compressed.

[0062] After resetting, the driving force on the air intake hopper 44 disappears, and under the elastic force of the reset spring bar 45, the air suction pump 42 drives the air intake hopper 44 to move in the opposite direction, and then the air intake hopper 44 moves back and forth, thereby increasing the suction range of harmful gases.

[0063] The third embodiment, as Figures 8-10As shown, a pressing assembly 5 is installed at the supporting leg at the bottom of the gantry 1, and the pressing assembly 5 includes a cylinder 51, which is fixedly installed at the supporting leg at the bottom of the gantry 1 through a bracket, and a right-angle connecting plate 52 is fixedly installed at the output end of the cylinder 51, and a pressing guide column 53 is slidably installed at the corresponding position on the top of the right-angle connecting plate 52, and a cylindrical spring 54 is fixedly installed between the top of the pressing guide column 53 and the top of the right-angle connecting plate 52, and a rolling ball 55 is rollingly installed on the bottom end of the pressing guide column 53 through a pin shaft, and a limiting module 56 is installed at the bottom of the right-angle connecting plate 52. The staff starts the cylinder 51 to work, and uses the extension of the output end of the cylinder 51 to drive the right-angle connecting plate 52 to move downward. At this time, under the sliding connection of the pressing guide column 53, the rolling ball 55 presses the motherboard raw material.

[0064] An inclined surface is provided at the bottom of the right-angle connecting plate 52. There are two cylinders 51, and the two cylinders 51 are symmetrically installed along the right-angle connecting plate 52. The pressing guide column 53 passes through the middle of the cylindrical spring 54. The pressing guide column 53 can slide and, under the elastic tension of the cylindrical spring 54, can be elastically pressed according to the different thicknesses of the vertical motherboard material.

[0065] The limiting module 56 includes a diamond-shaped elastic frame 561, the top of the diamond-shaped elastic frame 561 is fixedly installed in the middle of the outer side of the right-angle connecting plate 52, the bottom of the diamond-shaped elastic frame 561 is fixedly installed with a connecting base 562, the bottom of the connecting base 562 is fixedly installed with a limiting wedge 563, and a cylindrical roller 564 is rotatably installed on the side of the outer side of the limiting wedge 563. When the right-angle connecting plate 52 moves downward, and combined with the inclined surface provided at the bottom of the right-angle connecting plate 52, the inclined surface of the limiting wedge 563 is pressed. At this time, the symmetrical limiting wedges 563 on both sides move toward each other, so that the two vertical mother plate raw materials that need to be welded can be limited, so that the vertical mother plate raw materials are not easily skewed.

[0066] The limiting wedge block 563 is installed directly below the right-angle connecting plate 52, and the cylindrical rollers 564 are evenly distributed on the sides of the outer side of the limiting wedge block 563. The cylindrical rollers 564 can be used to make rolling contact with the edge of the outer side of the vertical mother plate raw material, reducing resistance and facilitating the movement of the entire equipment.

[0067] When in use, the staff first places the motherboard materials to be spliced ​​at the designated location and injects an appropriate amount of harmful gas reactants into the reagent box 41 so that the liquid level of the harmful gas reactants exceeds the outlet end of the suction pump 42;

[0068] At this time, a moving trolley is installed under the supporting legs at the bottom of the gantry 1, and the gantry 1 is driven to move by the linear drive 2. The overall position of the gantry 1 can be adjusted and the gantry 1 can be moved to the gap between the two vertical motherboard materials.

[0069] The extension of the output end of the cylinder 51 drives the right-angle connecting plate 52 downward. At this time, the sliding connection of the pressing guide pillar 53 causes the rolling ball 55 to press the vertical motherboard raw material. At the same time, the inclined surface of the limiting wedge 563 is pressed by the inclined surface at the bottom of the right-angle connecting plate 52. At this time, the limiting wedges 563 on both sides move toward each other symmetrically, thereby limiting the position of the two vertical motherboard raw materials to be welded, making it difficult for the vertical motherboard raw materials to be skewed. At this time, the vertical motherboard raw materials are fixed and will not move arbitrarily.

[0070] At this time, the welding gun 35 can be driven to move upward and downward by the contraction and extension of the output end of the lifter 34, and the height of the welding gun 35 can be adjusted so that the welding port at the bottom of the welding gun 35 is adjusted to a suitable position away from the vertical motherboard material to be welded. The staff starts the servo motor 32 to work. The rotation of the output end of the servo motor 32 drives the lead screw 31 to rotate, and under the sliding guide of the bar slider 33, the lifter 34 is driven to move linearly. At this time, the welding gun 35 is passively driven to move together to perform the welding work;

[0071] Furthermore, under the support and connection of the lifter 34, when the welding gun 35 is driven to move to the left for welding, the V-shaped elastic piece 365 is positioned at the gap between the two vertical motherboard materials to be welded under the support of the right-angle guide rod 362 and the zigzag scraper plate 364, and the V-shaped elastic piece 365 is driven to move to the left. At this time, the moving V-shaped elastic piece 365 will squeeze out the welding slag that falls into the gap between the vertical motherboard materials, making it difficult for the welding to get stuck in the gap between the vertical motherboard materials. The V-shaped elastic piece 365 is used to separate the welding slag to both sides.

[0072] At the same time, as the crescent block 363 continues to move downward, and under the rotation support of the right-angle guide rod 362, the force-bearing rod 367 drives the zigzag scraper plate 364 to rotate outward to adjust the angle, and the torque spring 366 is compressed. At this time, the symmetrical zigzag scraper plates 364 on both sides rotate together, and the welding slag at the edge of the gap between the raw materials of the vertical mother plate can be scraped and pushed to both sides, so that the welding slag can be removed from the gap between the raw materials of the vertical mother plate, thereby timely processing the welding slag.

[0073] When the output end of the electric telescopic rod 361 is retracted, the pressing force of the crescent block 363 on the top of the force-bearing rod 367 disappears, and under the torque force of the torque spring 366, the zigzag scraping plate 364 rotates in the opposite direction to reset, thereby facilitating the subsequent reciprocating scraping of the welding slag;

[0074] Furthermore, the suction pump 42 generates suction, and under the connection of the right-angle air pipe 43, the air inlet hopper 44 can increase the air intake volume, thereby absorbing the harmful gas generated by the welding gun 35 during welding, reducing the diffusion of the harmful gas, and through the connection of the right-angle air pipe 43, the air outlet end of the suction pump 42 discharges the absorbed harmful gas into the reagent box 41, so that the harmful gas fully contacts the harmful gas reaction reagent in the reagent box 41 and reacts;

[0075] At the same time, when the zigzag scraper plate 364 is rotated outward to adjust the angle, the welding slag at the gap can be scraped off, and an outward pushing force can be applied to the air intake hopper 44. Under the connection of the right-angle air pipe 43, the air suction pump 42 and the air intake hopper 44 slide to the left together, and the reset spring bar 45 is compressed. After the reset, the pushing force on the air intake hopper 44 disappears, and under the elastic force of the reset spring bar 45, the air suction pump 42 drives the air intake hopper 44 to move in the opposite direction, and then the air intake hopper 44 moves back and forth, which can increase the suction range of harmful gases.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
