Description

Technical Field

[0001] This application relates to the technical field of shipbuilding, and in particular to an auxiliary support for ship welding manufacturing. Background Technology

[0002] Ships are a general term for all kinds of vessels. Ships are means of transportation that can navigate or anchor in waterways for transportation or operations. Steel plate welding is a key process in shipbuilding. Through welding, steel plates are assembled into a complete hull. Before welding and assembly, pre-treatment work of sections and preparation work on the slipway should be carried out, and then section hoisting and section welding work are carried out.

[0003] During shipbuilding, each steel plate needs to be hoisted to the welding position on the hull. Currently, cranes or gantry cranes are usually used to hoist the steel plates to be welded to the designated position. However, during this hoisting process, the hoisted steel plates are prone to swinging and may collide with the hull or the mounting frames around the hull. Utility Model Content

[0004] In order to improve the efficiency of lifting steel plates and enable them to be accurately installed at the welding positions, this application provides an auxiliary support for ship welding manufacturing.

[0005] This application provides an auxiliary support for ship welding manufacturing, which adopts the following technical solution:

[0006] An auxiliary support for ship welding manufacturing includes a mounting frame assembly disposed beside the ship and a movable device movably disposed on the mounting frame assembly. The movable device is used to transport steel plates to be welded. The movable device includes a guide rail fixed to the mounting frame assembly and a movable plate slidably disposed on the guide rail. The guide rail is L-shaped and includes a vertical section and a horizontal section. The end of the horizontal section is fixed to the upper end of the vertical section. The movable plate can move from the lower end of the vertical section to the end of the horizontal section away from the vertical section. The steel plate to be welded can be mounted on the movable plate.

[0007] By adopting the above technical solution, during the installation of the steel plate to be welded, the steel plate can be fixed on the moving plate, and the moving plate can be moved along the direction of the guide rail by the set moving device. The lower end of the vertical section of the guide rail is the loading area for transporting steel plates, where the required steel plates can be installed on the moving plate. The end of the horizontal section of the guide rail away from the vertical section is the unloading area for transporting steel plates. After the steel plate moves to the unloading area, it is then moved to the position on the hull where it needs to be welded. During the transportation of the steel plate, the steel plate always moves along the direction of the guide rail, which avoids the steel plate shaking, prevents the steel plate from hitting the hull or the workers, and improves the transportation efficiency, allowing the steel plate to be quickly moved to the correct position.

[0008] Optionally, the guide rails are provided in a pair, and rollers are rotatably provided on the movable plate. The two guide rails are symmetrically arranged on both sides of the movable plate, and the rollers are rotatably engaged on the two guide rails. A lifting member is provided on the horizontal section of the guide rails away from the vertical section, and the lifting member controls the movable plate to move on the guide rails.

[0009] By adopting the above technical solution, the rollers rotating on the moving plate can roll and cooperate in the grooves of the guide rail, thereby allowing the moving plate to move more smoothly. The pair of guide rails symmetrically arranged on both sides of the moving plate can improve the stability of the moving plate and prevent the moving plate from tilting during movement. The lifting component set in the horizontal section of the guide rail can provide power for the movement of the moving plate.

[0010] Optionally, the moving device further includes a flipping assembly disposed on the moving plate. The flipping assembly includes a flipping plate rotatably disposed on the moving plate and a flipping component for controlling the rotation of the flipping plate. The length direction of the flipping plate is the same as the moving direction of the moving plate, and the end of the flipping plate away from the vertical section of the guide rail is rotatably connected to the moving plate. The steel plate to be welded is installed on the flipping plate.

[0011] By adopting the above technical solution, after the steel plate is moved to the designated position, the flipping motor controls the flipping plate to rotate, which allows the horizontal steel plate to rotate to any angle, making it convenient to accurately move the steel plate to any complex welding position. In addition, since the hull is curved, the steel plate can be rotated to any position, making it suitable for complex splicing and installation environments.

[0012] Optionally, the moving device further includes a rotating assembly mounted on the flip plate. The rotating assembly includes a rotating plate arranged parallel to the flip plate and a rotating component mounted on the flip plate. The rotating component controls the rotating plate to rotate on the flip plate, and the steel plate to be welded can be mounted on the rotating plate.

[0013] By adopting the above technical solution, when transporting steel plates to be welded, since the length and width of the steel plates are different, in order to facilitate the lifting of the longer steel plates onto the horizontal section of the guide rail, the steel plates can be fixed on the rotating plate in the same way as the moving plate. When the moving plate moves to the horizontal section, the steel plates are rotated to a suitable angle by the rotating component and transported to the position where welding is required.

[0014] Optionally, the rotating plate is provided with a fixing assembly for fixing the steel plate to be welded. The fixing assembly includes a connecting rod fixed on the rotating plate and an electromagnet fixed on the end of the connecting rod away from the rotating plate. The electromagnet is attracted to the steel plate to be welded.

[0015] By adopting the above technical solution, when installing the steel plate to be welded, the electromagnet is firmly attracted to the steel plate after being energized, and then fixed to the rotating plate by the connecting rod, thus avoiding the problem of the curved steel plate not being able to be installed flat on the rotating plate.

[0016] Optionally, multiple sets of fixing components are provided on the rotating plate, and the multiple sets of fixing components are evenly arranged on the rotating plate.

[0017] By adopting the above technical solution, the multiple sets of fixing components can increase the connection strength between the steel plate and the rotating plate, and prevent the steel plate from falling off the rotating plate.

[0018] Optionally, the connecting rod includes a fixed part and a telescopic part, the telescopic part is slidably inserted into the fixed part, the upper end of the telescopic part is fixed to the electromagnet, and a fixing bolt is provided at the connection between the fixed part and the telescopic part to restrict the sliding of the telescopic part.

[0019] By adopting the above technical solution, since the transported steel plates are not all flat, for curved steel plates, during the installation process, the length of the extension of the telescopic part on each connecting rod is adjusted so that each electromagnet can be attracted to the steel plate.

[0020] Optionally, a hinged ball is fixed at the upper end of the telescopic part, and the telescopic part and the electromagnet are connected by the hinged ball to achieve ball hinge rotation.

[0021] By adopting the above technical solution, the articulated ball is rotatably embedded in the electromagnet, allowing the electromagnet to rotate freely around the articulated ball. This allows the electromagnet to adapt to different curved steel plates and to fit completely onto the curved surface of the steel plate.

[0022] Optionally, a lifting device is provided on the mounting frame assembly at the position of the horizontal section of the guide rail. The horizontal and vertical sections of the guide rail are assembled separately. The lifting device can control the vertical movement of the horizontal section of the guide rail. The lifting device includes a fixing plate fixed on the mounting frame assembly and multiple sets of lifting cylinders installed on the fixing plate. The lifting cylinders control the vertical movement of the horizontal section of the guide rail.

[0023] By adopting the above technical solution, a lifting cylinder is set to control the vertical movement of the horizontal section. In the initial state, the horizontal section and the vertical section are connected. When the moving plate transports the steel plate to the horizontal section, the lifting cylinder is activated to allow the moving plate to move vertically and the transported steel plate to move vertically. This avoids the transported steel plate not being accurately transported to the welding position by the mounting frame assembly. The lifting device is used to compensate for the existing installation errors.

[0024] Optionally, the mounting frame assembly is a modular structure, comprising a stable frame supported on the ground, a fixed frame mounted on the stable frame, and an extension frame positioned between the stable frame and the fixed frame. The guide rail and the movable plate are both mounted on the fixed frame, and the vertical sections of the guide rail can be assembled by splicing.

[0025] By adopting the above technical solution, staff can choose whether to install an extension frame according to the needs of production and manufacturing. When the hull height is high, the extension frame can be installed between the stabilizing frame and the fixed frame to increase the overall height of the mounting frame assembly.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. During the transportation of steel plates to be welded, the moving plate can be pulled by the lifting components and moved from the loading area of ​​the vertical section of the guide rail to the unloading area of ​​the horizontal section of the guide rail. During the transportation process, the steel plate is always fixed to the moving plate by the fixing components, making the transportation process of the steel plate more stable and preventing the steel plate from hitting the hull, the mounting frame components or the personnel during the transportation process.

[0028] 2. After the steel plate is transported to the unloading area of ​​the guide rail, it can be moved to the correct position by the flipping and rotating components, so that it can be accurately moved to the welding position on the ship hull, thus improving the efficiency of installing the steel plate to be welded.

[0036] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0037] This application discloses an auxiliary support for ship welding manufacturing.

[0038] Reference Figure 1An auxiliary support for ship welding manufacturing includes a mounting frame assembly 1 arranged around the hull and a moving device 2 arranged on the mounting frame assembly 1. The mounting frame assembly 1 is arranged along the height direction of the hull. The moving device 2 is used to install steel plates for welding. The moving device 2 is slidably arranged on the mounting frame assembly 1. During the welding manufacturing process of the ship, the steel plate to be welded is installed on the moving device 2, allowing the moving device 2 to move on the mounting frame assembly 1 and transport the steel plate to be welded to a designated position.

[0039] Mounting frame assembly 1 includes a stabilizing frame 11 supported on the ground, a fixing frame 12 mounted on the stabilizing frame 11, and an extension frame 13 disposed between the stabilizing frame 11 and the fixing frame 12. A moving device 2 is disposed on the fixing frame 12. The stabilizing frame 11, the fixing frame 12, and the extension frame 13 can be spliced ​​and combined, and all three are rectangular frame structures. The extension frame 13 can be installed and fitted onto the stabilizing frame 11, and the fixing frame 12 can be installed and fitted onto the extension frame 13, thereby increasing the height of the mounting frame assembly 1 to accommodate ships of different heights. Multiple sets of extension frames 13 are provided, and workers can select different numbers of extension frames 13 according to production and manufacturing needs to build mounting frame assemblies 1 of different heights to suit ships of different heights. Construction platforms 14 are symmetrically fixed near the upper end of the fixing frame 12 and on both sides thereof. The construction platforms 14 provide a construction area for workers to perform welding operations.

[0040] Reference Figure 1The stabilizer frame 11 is equipped with multiple stabilizing plates 15, which are arranged in parallel. The length direction of the stabilizing plates 15 is the same as the width direction of the stabilizer frame 11. The lower end of the stabilizer frame 11 is fixed to the multiple stabilizing plates 15, thereby improving the stability of the stabilizer frame 11. Each end of the stabilizing plate 15 is fixed with a self-locking caster wheel 16, which facilitates the movement of the mounting frame assembly 1 to the required position during use, improving the flexibility of the mounting frame assembly 1. Both the stabilizer frame 11 and the fixing frame 12 are equipped with connecting components 17 for connection to the hull. The connecting components 17 include a reinforcing rod 171 horizontally fixed to the stabilizer frame 11 and a reinforcing rod 171 fixed to the hull. The connecting block 172 at the end of the reinforcing rod 171 extends towards the hull. The connecting block 172 is fixed at the end of the reinforcing rod 171 away from the stabilizer 11. The connecting block 172 can be connected and fixed to the hull. When using the mounting bracket assembly 1, the mounting bracket assembly 1 can be connected and fixed to the hull to prevent it from tipping over. The connecting block 172 can be a magnetic block or it can be welded to the hull, or it can be hooked to the hull. The reinforcing rod 171 is a telescopic structure. Since the hull has an arc-shaped structure and is wider at the top and narrower at the bottom, the telescopic reinforcing rod 171 can be stretched to allow the connecting block 172 to be better connected to the hull.

[0041] Reference Figure 1 and Figure 2The moving device 2 includes an L-shaped guide rail 21 mounted on the fixed frame 12. The guide rail 21 is provided in pairs and has a U-shaped cross-section. A moving plate 22 is slidably arranged between the two guide rails 21. The moving plate 22 can slide along the length direction of the guide rail 21. Multiple rollers 221 are rotatably arranged on the moving plate 22. The rollers 221 are rotatably engaged in the grooves of the guide rails 21 to prevent the moving plate 22 from disengaging from the two guide rails 21 during the sliding process. The guide rail 21 includes a horizontal section 211 horizontally mounted on the fixed frame 12 and a vertical section 212 mounted on the fixed frame 12, the extension frame 13, and the stabilizing frame 11. The end of the horizontal section 211 is fixed to the upper end of the vertical section 212, and the connection between the horizontal section 211 and the vertical section 212 is set as a curved arc to facilitate the movement of the moving plate 22 from the vertical section 212 to the horizontal section 211. The end of the horizontal section 211 away from the vertical section 212 extends towards the hull, and the vertical section 212 passes vertically through the fixed frame 12. 2. Extension frame 13 and stabilizer frame 11, and the vertical section 212 is a splicable structure. When the length of extension frame 13 is increased, the length of the vertical section 212 of guide rail 21 is increased accordingly. When the steel plate needs to be transported to the welding position on the hull, control the moving plate 22 to move to the lower end of the vertical section 212 of guide rail 21, and then install and fix the steel plate on the moving plate 22. Then control the moving plate 22 to move to the horizontal section 211 of guide rail 21, and finally transport the steel plate to the welding position.

[0042] Reference Figure 2 and Figure 3 A lifting member 23 for controlling the movement of the movable plate 22 is provided below the horizontal section 211 of the guide rail 21 and at a position away from the vertical section 212. The lifting member 23 includes a lifting roller 231 rotatably mounted on the guide rail 21. A pull rope 232 is wound around the lifting roller 231. One end of the pull rope 232 is fixed to the lifting roller 231, and the other end is fixed to the movable plate 22 at a position away from the hull. A lifting motor 233 for controlling the rotation of the lifting roller 231 is fixed on the guide rail 21. When it is necessary to move the movable plate 22 from the lower end of the vertical section 212 of the guide rail 21 to the horizontal section 211 of the guide rail 21, the lifting motor 233 is started. Under the action of the lifting roller 231 and the pull rope 232, the movable plate 22 is pulled and the steel plate to be welded is moved to the horizontal section 211 of the guide rail 21, so that the movable plate 22 moves on the horizontal section 211 of the guide rail 21 and moves to the position on the hull where welding is required.

[0043] The moving device 2 also includes a flipping assembly 24 disposed on the moving plate 22. The flipping assembly 24 includes a flipping plate 241 rotatably disposed on the upper surface of the moving plate 22. The length direction of the flipping plate 241 is the same as the length direction of the moving plate 22 and is disposed along the moving direction of the moving plate 22. A rotating shaft 242 is disposed at the end of the flipping plate 241 near the hull. The two ends of the rotating shaft 242 are rotatably connected to the moving plate 22. Flipping components for controlling the rotation of the flipping plate 241 are disposed on the moving plate 22 at both ends of the rotating shaft 242. The flipping components include a worm gear 243 sleeved and fixed to the end of the rotating shaft 242 and a worm 244 rotatably disposed on the moving plate 22. The worm gear 243 and the worm 244 mesh. Furthermore, a tilting motor 245 that drives the worm gear 244 to rotate is fixed on the movable plate 22. The steel plate to be welded can be installed on the tilting plate 241. When the steel plate moves to the designated position, the tilting motor 245 is started and the tilting plate 241 is rotated, which can rotate the steel plate laid flat on the tilting plate 241 into a vertical state, making it convenient to move the steel plate accurately to the position to be welded. In addition, since the tilting plate 241 and the movable plate 22 are driven by the worm gear 243 and the worm 244, the angle of rotation of the tilting plate 241 on the movable plate 22 can be controlled to be greater than 90 degrees. And since the outer surface of the hull is curved, it can be moved to the correct position, making it suitable for complex splicing and installation environments.

[0044] Reference Figure 2 and Figure 3 The moving device 2 also includes a rotating assembly 25 mounted on the mounting plate. The rotating assembly 25 includes a rotating plate 251 parallel to the flip plate 241 and a rotating component mounted on the flip plate 241. The rotating component includes a rotating motor 252 that passes through and is fixed on the flip plate 241. The output shaft of the rotating motor 252 is fixed at the center of the rotating plate 251. The steel plate to be installed can be fixed on the flip plate 241. When transporting the steel plate to be welded, since the length and width of the steel plates are different, in order to facilitate lifting the longer steel plate onto the horizontal section 211 of the guide rail 21, the steel plate can be fixed on the rotating plate 251 in the same way as the moving plate 22. When the moving plate 22 moves to the horizontal section 211, the rotating motor 252 is started to rotate the steel plate to a suitable angle and transport it to the position where welding is required.

[0045] The moving device 2 also includes a fixing assembly 26 disposed on the rotating plate 251. The fixing assembly 26 is used to fix the steel plate to be welded, preventing the steel plate from falling off the rotating plate 251 during the movement of the moving plate 22. Multiple sets of fixing assemblies 26 are disposed on the rotating plate 251. Through multiple sets of fixing assemblies 26, the steel plate to be welded is fixed more firmly, preventing it from falling off the rotating plate 251. The fixing assembly 26 includes a connecting rod 261 vertically fixed on the rotating plate 251. The connecting rod 261 is a telescopic rod, which includes a fixed part and a telescopic part. The fixed part is vertically fixed on the rotating plate 251, and the telescopic part is slidably inserted into the fixed part. The end of the telescopic part is threaded with a fixing bolt 262, which passes through the fixing part and abuts against the telescopic part. After the sliding adjustment is completed, the fixing bolt 262 is tightened. An electromagnet 263 for use is fixed at the upper end of the telescopic part. The electromagnet 263 is used to attract the transported steel plate. The multiple electromagnets 263 set on the connecting rod 261 improve the connection strength with the steel plate to be welded and prevent the steel plate from falling off during transportation. In addition, since the transported steel plate is not entirely flat, for curved steel plates, the length of the telescopic part on each connecting rod 261 is adjusted during installation so that each electromagnet 263 can attract the steel plate. A hinge ball 264 is fixed at the position where the telescopic part of the connecting rod 261 connects with the electromagnet 263. The hinge ball 264 is rotatably embedded in the electromagnet 263, allowing the electromagnet 263 to rotate freely around the hinge ball 264. This allows the electromagnet 263 to adapt to different curved steel plates and to fit completely onto the curved surface of the steel plate.

[0046] Reference Figure 2 and Figure 3 A lifting device 3 is installed on the fixed frame 12 and below the horizontal section 211 of the guide rail 21. The lifting device 3 includes a horizontally fixed plate 31 fixed to the fixed frame 12. Multiple vertically arranged lifting cylinders 32 are installed on the fixed plate 31. The multiple lifting cylinders 32 are evenly arranged on the fixed plate 31 and are fixed to the fixed plate 31 through the plate. The horizontal section 211 and the vertical section 212 of the guide rail 21 are separate. The piston rod end of the lifting cylinder 32 is connected to the guide rail 21. The horizontal section 211 of the rail 21 is fixedly connected. The vertical movement of the horizontal section 211 is controlled by the lifting cylinder 32. In the initial state, the horizontal section 211 and the vertical section 212 are connected. When the moving plate 22 transports the steel plate to the horizontal section 211, the lifting cylinder 32 is activated to allow the moving plate 22 to move vertically and the transported steel plate to move vertically. This prevents the transported steel plate from being inaccurately transported to the welding position by the mounting frame assembly 1. The lifting device 3 is used to compensate for any installation errors.

[0047] The implementation principle of an auxiliary support for ship welding manufacturing according to an embodiment of this application is as follows: During the transportation of the steel plate to be welded, the moving plate 22 is moved to the initial position. The worker fixes the steel plate to the rotating plate 251 using the fixing component 26. Then, the moving plate 22 is moved to the horizontal section 211 of the guide rail 21 by the lifting component 23, so that the steel plate can be close to the position to be welded. During the transportation process, according to the shape of the position of the steel plate to be welded, the placement position of the steel plate to be welded is adjusted by the flipping component 24 and the rotating component 25, so that the steel plate can be accurately installed in the correct position. In addition, during the adjustment of the position of the steel plate, the position error of the steel plate can also be adjusted vertically by the lifting device 3, so that the steel plate to be welded can be installed in the correct position.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments.
