Description

Technical Field

[0001] This invention relates to the field of photovoltaic pipe pile production, specifically to a photovoltaic pipe pile transfer tooling and spraying device. Background Technology

[0002] As the core foundational load-bearing component of offshore photovoltaic projects, the market demand for photovoltaic (PV) pipe piles continues to rise, and the industry's need to improve the overall production efficiency of pipe piles is becoming increasingly urgent. Meanwhile, PV pipe piles are used in the marine environment for extended periods, and their corrosion resistance directly affects the structural service life and operational safety. Therefore, anti-corrosion spraying after the PV pipe piles leave the factory is a necessary step in the production process.

[0003] Photovoltaic pipe piles are mostly long, cylindrical structures, with considerable length and weight. During production, batch transport is required, placing high demands on the load-bearing stability, structural adaptability, and coordination of subsequent anti-corrosion coating processes of the transport fixture. Patent document CN221092173U discloses a steel pipe pile transport fixture, which can be used not only for transporting steel pipe piles but also for placing similar cylindrical, frustum-shaped, or conical items such as towers and utility poles. The core function of this steel pipe pile transport fixture is the sea transport of steel pipe piles. Since the external structure of photovoltaic pipe piles is essentially similar to that of steel pipe piles, this fixture can theoretically be used for the transport of photovoltaic pipe piles.

[0004] However, considering the production process characteristics and large-scale production needs of photovoltaic (PV) pipe piles, its application still has shortcomings: the transport fixture only has a single transfer function and lacks any flipping structure. Offshore PV pipe piles require circumferential outer surface anti-corrosion spraying, and welding operations are also necessary during production. After using this fixture to transfer the PV pipe piles to the corresponding workstation, additional dedicated flipping fixtures are needed for spraying, and dedicated welding fixtures for welding operations. This makes it impossible to effectively connect transfer, spraying, and welding, requiring multiple hoisting and fixture changes, which not only increases fixture investment costs but also severely restricts production efficiency. To address these shortcomings, there is an urgent need for a PV pipe pile transfer fixture and spraying device that can effectively connect transfer, welding, and spraying, and is suitable for batch operations. Summary of the Invention

[0005] To address the problem that existing transport fixtures used for photovoltaic (PV) pipe pile transfer suffer from limited functionality and lack of a flipping structure, hindering effective integration of transfer with spraying and welding processes and requiring additional flipping and welding fixtures, thus limiting production efficiency, this invention proposes a PV pipe pile transfer fixture and spraying device. By integrating a flipping component into the fixture body, the connection between transfer, spraying, and welding is broken down. This allows for coordinated operations of layered batch transfer and storage of PV pipe piles, welding, and anti-corrosion spraying, achieving multi-purpose functionality with a single fixture, effectively improving production efficiency, and adapting to the needs of large-scale offshore PV pipe pile production.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A photovoltaic (PV) pipe pile transfer fixture includes a main body that cooperates with a transport vehicle. The main body includes two opposing columns, with a support unit for supporting the PV pipe pile positioned between the columns. The support unit includes a first support unit and at least one second support unit arranged sequentially from bottom to top. Both the first and second support units include several sets of tilting units. Each tilting unit includes two rollers, and the PV pipe pile is placed on the two rollers of each tilting unit. The core configuration of the PV pipe pile transfer fixture is a main body adapted to the transport vehicle, thereby achieving stable support and transfer of the PV pipe pile. The photovoltaic (PV) pipe piles are directly mounted on two rollers in each set of flipping units. This provides stable and limiting support for the PV pipe piles and allows the rollers to rotate circumferentially, facilitating subsequent surface anti-corrosion spraying. To accommodate the PV pipe piles, multiple sets of tooling bodies can be spaced out and flexibly configured along the length of the transport vehicle. The coordinated support of these parallel tooling bodies ensures reliable load-bearing at both ends and the middle of the PV pipe piles. The transport vehicle is a self-propelled modular transport vehicle with a built-in lifting function. Specifically, before the transfer operation, the self-propelled modular transport vehicle lifts the tooling body to stably support it, thus enabling the overall transfer of the tooling body and the PV pipe pile. On the other hand, when it is necessary to detach the tooling body from the transport vehicle, the self-propelled modular transport vehicle lowers its body to allow the tooling body to detach from the vehicle's support and land independently. The separation and mounting of the tooling body is achieved through the self-propelled modular transport vehicle's own lifting action. Based on the above structural design, this device can be placed independently without a transport vehicle, thus possessing the function of photovoltaic pile storage.

[0007] Furthermore, the support unit one also includes a crossbeam one, with both ends of the crossbeam one welded to two columns. To meet the operational requirements of layered batch support for photovoltaic (PV) pipe piles, a standardized loading method is adopted, proceeding from bottom to top. The workflow is as follows: first, the bottom layer of PV pipe piles is loaded, then the upper support unit two is installed layer by layer, followed by the loading of the upper PV pipe piles. Based on this layer-by-layer loading logic, the crossbeam one, as the bottommost load-bearing structure of the tooling, experiences no structural interference during assembly and use. When installing the crossbeam one and laying out the bottom layer of PV pipe piles, the upper support unit two and the crossbeam two are not yet assembled, providing ample working space. Therefore, there is no need to consider the obstruction or influence of the upper structure; hence, the crossbeam one is fixed to the columns by welding.

[0008] Furthermore, the second support unit also includes a second crossbeam, with brackets provided on the opposite sides of the two columns, and both ends of the second crossbeam resting on the brackets. The second crossbeam forms a detachable overlapping structure with the columns through the brackets. Based on the above-mentioned bottom-to-top layer-by-layer loading operation mode, the unloading operation adopts a top-to-bottom operation process. During unloading, the upper-layer photovoltaic pipe piles are hoisted and removed first, and then the second crossbeams at the corresponding positions are dismantled, and the operation proceeds layer by layer downwards. The overlapping structure between the second crossbeam and the bracket facilitates disassembly and assembly. After the upper-layer photovoltaic pipe piles are removed, the second crossbeam can be directly removed from the bracket, thereby completing the dismantling of the second crossbeams of each layer and the step-by-step unloading of the photovoltaic pipe piles.

[0009] Furthermore, several sets of the flipping units are evenly distributed along the length of the first or second crossbeam. Each set of flipping units includes a base and a set of supports at both ends above the base, with two supports in each set. The rollers are rotatably mounted on the corresponding two supports, one of which is equipped with a motor. The rollers are mounted on the output end of the motor. Each motor can independently drive the corresponding roller to rotate, thereby causing the photovoltaic pile erected between the two sets of rollers to rotate smoothly in the circumferential direction.

[0010] Furthermore, each of the columns is also equipped with a surrounding panel, which is a U-shaped panel with one end open, facing the second crossbeam. Combined with the detachable overlapping structure of the second crossbeam, the U-shaped surrounding panel can provide reliable lateral restraint to the ends of the second crossbeam, preventing it from shifting.

[0011] Furthermore, the base is connected to either crossbeam one or crossbeam two via bolts. This assembly method allows each flipping unit to form an independent modular structure, facilitating flexible adjustment of the layout spacing and number of flipping units, while also facilitating later maintenance and replacement of individual flipping units.

[0012] The present invention also discloses a photovoltaic pipe pile spraying device. The photovoltaic pipe pile is transported to the photovoltaic pipe pile spraying device station by the aforementioned photovoltaic pipe pile transfer tool for anti-corrosion spraying. The spraying device includes two sets of spraying units placed opposite each other. Each set of spraying units includes several ground piles distributed at intervals. The upper ends of the several ground piles are jointly installed with a guide rail unit. Several sets of moving units are slidably arranged on the guide rail unit. Each set of moving units has a spraying robot installed on the side facing the photovoltaic pipe pile. The photovoltaic pipe pile spraying device works in coordination with the aforementioned photovoltaic pipe pile transfer fixture. The photovoltaic pipe pile is directly transferred to the spraying station via the photovoltaic pipe pile transfer fixture without secondary hoisting or repeated clamping. The photovoltaic pipe pile transfer fixture can also serve as the load-bearing fixture for the spraying operation. Two sets of spraying units in the spraying device are symmetrically arranged on both sides of the multi-layer photovoltaic pipe pile on the main body of the fixture and are fixedly supported by ground piles. The upper end of the ground piles is fixedly installed with a guide rail unit, which extends along the length of the photovoltaic pipe pile and is adapted to the multiple sets of fixture bodies distributed at intervals in the photovoltaic pipe pile transfer fixture. During the anti-corrosion spraying operation, the moving unit slides smoothly along the guide rail unit, driving the spraying robot to move synchronously along the axis of the photovoltaic pipe pile. At the same time, the flipping unit in the aforementioned photovoltaic pipe pile transfer fixture drives the photovoltaic pipe pile to perform a smooth circumferential flipping. The two work together to achieve anti-corrosion spraying without dead angles on the circumferential outer surface of the photovoltaic pipe pile.

[0013] Furthermore, the guide rail unit includes a guide seat and an upper guide rail and a lower guide rail disposed on the guide seat. The guide rail unit adopts a combined structure of upper and lower guide rails, which forms a bidirectional limiting and guiding structure for the moving unit, effectively improving the running stability of the moving unit during the sliding process along the guide rail unit.

[0014] Furthermore, the moving unit includes a mounting base and a drive unit mounted on the mounting base. The mounting base is L-shaped and includes a horizontal portion and a vertical portion. A slider 1 that mates with the upper guide rail is mounted on the horizontal portion of the mounting base, and a slider 2 that mates with the lower guide rail is mounted on the vertical portion of the mounting base. Based on the structural layout of the L-shaped mounting base, the moving unit forms limiting and guiding relationships with the aforementioned guide rail units from the top and side, respectively. Simultaneously, the sliding engagement of slider 1 with the upper guide rail and slider 2 with the lower guide rail ensures stable and reliable movement of the painting robot.

[0015] Furthermore, the drive unit includes a second motor and a driving gear mounted on the output end of the second motor. The second motor is fixed to the horizontal part of the mounting base. A rack is also provided on the guide seat, and the rack is arranged parallel to the upper guide rail. The driving gear meshes with the rack. A driven gear is also provided on the horizontal part of the mounting base, and the driven gear meshes with the rack. The second motor drives the driving gear to rotate, and the meshing transmission between the driving gear and the rack generates moving power, thereby driving the overall moving unit to move along the guide rail unit to achieve displacement, thus driving the painting robot to move smoothly. The driven gear has no independent power input, moves synchronously with the moving unit and is passively meshed with the rack, effectively compensating for the fit clearance existing in single gear transmission and ensuring the smooth operation of the moving unit.

[0016] The beneficial effects of the present invention through the above technical solution are as follows: The core innovation of this invention lies in breaking through the single-function limitations of traditional transport fixtures, eliminating the barriers between transport, spraying, and welding, and enabling coordinated transport and storage of photovoltaic pipe piles in layers, welding operations, and anti-corrosion spraying. This achieves multi-purpose functionality with a single fixture, eliminating the need for additional dedicated welding and spraying fixtures, effectively reducing fixture investment and modification costs, and avoiding efficiency losses caused by repeated hoisting and fixture replacements. By integrating an independently driven tilting unit into the main body of the fixture, it not only overcomes the deficiency of traditional transport fixtures lacking a tilting structure, but also provides a more efficient tilting mechanism for welding and spraying operations. Conveniently designed, the flipping unit drives the photovoltaic pile to rotate smoothly in the circumferential direction, facilitating the anti-corrosion spraying by the spraying robot and adjusting the welding angle of the photovoltaic pile. This reduces the intensity of manual operation and improves the quality and efficiency of welding and spraying. In addition, the spraying device adopts a dual-guide rail limiting guide combined with an L-shaped mounting base, and a transmission structure combining a drive gear and a driven gear meshing rack to ensure the smooth movement of the spraying robot. At the same time, the synchronous coordination between the circumferential flipping of the photovoltaic pile and the axial movement of the spraying robot enables anti-corrosion spraying of the outer circumferential surface of the photovoltaic pile without dead angles, meeting the anti-corrosion requirements of offshore photovoltaic piles.

[0017] Secondly, the main body of the tooling in this invention adopts a layered support structure. The bottom crossbeam is welded and fixed, while the upper crossbeam is detachably overlapped, adapting to the standard operation mode of loading from bottom to top and disassembling from top to bottom, which can meet the needs of layered batch stacking and transportation of photovoltaic pipe piles. Combined with a self-propelled modular transport vehicle with a built-in lifting function, the tooling main body can be loaded and detached. The tooling main body can be placed independently detached from the vehicle body, serving as both a photovoltaic pipe pile storage function and a welding and painting operation platform. Furthermore, the flipping unit adopts a modular installation structure, which can flexibly adjust the layout spacing and quantity according to different specifications of photovoltaic pipe piles, and facilitates individual maintenance and replacement later, effectively reducing the difficulty of operation and maintenance.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-6 As shown, this embodiment provides a photovoltaic pipe pile transfer fixture, including a fixture body that cooperates with a transport vehicle. The fixture body includes two opposing columns 1, and a support unit for supporting the photovoltaic pipe pile is provided between the two columns 1. The support unit includes a support unit one and at least one set of support units two arranged sequentially from bottom to top. Both the support unit one and the support unit two include several sets of flipping units. Each set of flipping units includes two rollers 2, and the photovoltaic pipe pile is placed on the two rollers 2 of each set of flipping units.

[0021] In this embodiment, the core configuration of the photovoltaic pipe pile transfer fixture is a fixture body adapted to the transport vehicle, thereby achieving stable bearing and transfer of the photovoltaic pipe pile. The fixture body is assembled from two opposing columns 1 to form an overall frame. Multiple layers of support units are vertically arranged between the columns 1. Each support unit includes support unit one and at least one set of support unit two. Multiple sets of flipping units are arranged on each layer of support unit. The photovoltaic pipe pile is directly mounted on the two rollers 2 of each set of flipping units, which can not only provide stable limiting support for the photovoltaic pipe pile, but also use the rotation characteristics of the rollers 2 to drive the pipe pile to rotate circumferentially, providing operational convenience for subsequent surface anti-corrosion spraying processes. To adapt to the photovoltaic pipe pile, multiple sets of fixture bodies can be distributed and flexibly configured at intervals along the length of the transport vehicle, and the coordinated support of multiple sets of parallel fixture bodies... To ensure reliable support for both ends and the middle of the photovoltaic (PV) pipe pile, the applicant should note that the transport vehicle is a self-propelled modular transport vehicle with a built-in lifting function. Specifically, before the transfer operation, the self-propelled modular transport vehicle lifts the main body of the tooling, thus enabling the overall transfer of the tooling and the PV pipe pile. Conversely, when it is necessary to detach the tooling from the transport vehicle, the self-propelled modular transport vehicle lowers itself, allowing the tooling to detach from the vehicle's support and land independently. The lifting function of the self-propelled modular transport vehicle itself facilitates the separation and mounting of the tooling. Based on this structural design, the device can be placed independently of the transport vehicle, thus providing PV pipe pile storage functionality and effectively expanding the overall applicability of the device.

[0022] Please refer to this again. Figure 2 The support unit one also includes a crossbeam one 3, the two ends of which are welded to two columns 1 respectively. To meet the operational requirements of layered batch support of photovoltaic pipe piles, this device adopts a standardized loading method from bottom to top. The operation process is as follows: first, the loading of the bottom layer of photovoltaic pipe piles is completed, then the upper support unit two is installed layer by layer, and the upper photovoltaic pipe piles are loaded. Based on the above layer-by-layer loading logic, the crossbeam one 3, as the bottom-most load-bearing structure of the tooling main body, has no structural interference during assembly and use; when installing the crossbeam one 3 and laying the bottom layer of photovoltaic pipe piles, the upper support unit two and the crossbeam two 4 have not yet been assembled, and there is sufficient working space, so there is no need to consider the obstruction and influence of the upper structure. Therefore, the crossbeam one 3 and the columns 1 are connected by welding.

[0023] In this embodiment, the second support unit also includes a second crossbeam 4, and brackets 5 are provided on the opposite sides of the two columns 1. The two ends of the second crossbeam 4 are placed on the brackets 5. The second crossbeam 4 is the main load-bearing component of the second support unit, and forms a detachable overlapping structure with the columns 1 through the brackets 5. Based on the above-mentioned bottom-to-top layer-by-layer loading operation mode, the unloading operation adopts a top-to-bottom operation process. During unloading, the upper photovoltaic pipe piles are hoisted and removed first, and then the corresponding positions of the second crossbeam 4 are removed, and the operation is carried out layer by layer downwards. The overlapping structure between the second crossbeam 4 and the bracket 5 is easy to disassemble and assemble. After the upper photovoltaic pipe piles are removed, the second crossbeam 4 can be directly removed from the bracket 5, thereby completing the disassembly of each layer of the second crossbeam 4 and the step-by-step unloading of the photovoltaic pipe piles.

[0024] Please refer to this again. Figure 4 Several sets of flipping units are evenly distributed along the length of the first beam 3 or the second beam 4. Each set of flipping units includes a base 6 and a set of supports 7 located at both ends above the base 6. There are two supports 7 in each set. The rollers 2 are rotatably mounted on the corresponding two supports 7. One of the supports 7 is equipped with a motor 8, and the rollers 2 are mounted on the output end of the motor 8. It should be noted that the power transmission between the output end of the motor 8 and the central support shaft of the roller 2 can be completed through conventional transmission components such as gear transmission, synchronous belt transmission, or chain transmission. Each motor 8 can independently drive the corresponding roller 2 to rotate, thereby driving the photovoltaic tube pile mounted between the two sets of rollers 2 to rotate smoothly in the circumferential direction. This not only allows for seamless spraying of the outer circumferential surface of the photovoltaic tube pile with the help of the spraying robot 11, but also allows for adjustment of the rotation angle of the photovoltaic tube pile according to welding requirements, ensuring that the welding part is always in a position convenient for the operator to weld, eliminating the need for manual flipping of the tube pile. This fully demonstrates the multi-purpose advantages of this tooling for transportation, welding, and spraying.

[0025] Please refer to this again. Figure 3 Each of the columns 1 is also equipped with a surrounding plate 9, which is a U-shaped plate with one end open, and the opening of the surrounding plate 9 faces the second crossbeam 4. Combined with the detachable and overlapping structural feature of the second crossbeam 4, the U-shaped surrounding plate 9 can form a reliable lateral limiting constraint on the end of the second crossbeam 4, preventing the second crossbeam 4 from shifting during transportation, and further improving the structural stability of the photovoltaic pile during transportation.

[0026] It is worth mentioning that the base 6 is connected to either the first crossbeam 3 or the second crossbeam 4 by bolts. This assembly method allows each flipping unit to form an independent modular structure, which can flexibly adjust the layout spacing and number of flipping units according to the specifications and dimensions of the photovoltaic pile. At the same time, it facilitates the maintenance and replacement of individual flipping units in the later stage, effectively reducing operation and maintenance costs.

[0027] The flipping unit in this device is the core driving structure for subsequent anti-corrosion spraying and welding operations of photovoltaic pipe piles. It eliminates the need for additional spraying and welding fixtures at the spraying and welding stations, and can be directly used in conjunction with the subsequent photovoltaic pipe pile spraying device. Anti-corrosion spraying can be carried out directly after the photovoltaic pipe piles are transported and positioned, effectively breaking down the barriers between the transport process and the spraying and welding processes, achieving multi-process collaborative operation. The welding operation in the photovoltaic pipe pile production process is a conventional welding procedure, requiring no dedicated welding equipment. It only needs to provide stable support and rotation angle adjustment for the photovoltaic pipe piles; therefore, conventional welding operations can be completed using the main fixture.

[0028] like Figures 7-9 As shown, the present invention also discloses a photovoltaic pipe pile spraying device. The photovoltaic pipe pile is transported to the photovoltaic pipe pile spraying device station by the aforementioned photovoltaic pipe pile transfer tool for anti-corrosion spraying. The spraying device includes two sets of spraying units placed opposite each other. Each set of spraying units includes a plurality of ground piles 10 distributed at intervals. The upper ends of the plurality of ground piles 10 are jointly installed with a guide rail unit. A plurality of moving units are slidably arranged on the guide rail unit. Each set of moving units has a spraying robot 11 installed on the side facing the photovoltaic pipe pile.

[0029] In this embodiment, the photovoltaic pipe pile spraying device and the aforementioned photovoltaic pipe pile transfer fixture work together. The photovoltaic pipe piles are directly transferred to the spraying station via the aforementioned photovoltaic pipe pile transfer fixture, eliminating the need for secondary hoisting and repeated clamping. The photovoltaic pipe pile transfer fixture can also serve as a load-bearing fixture for the spraying operation; please refer again to Figure 1 The spraying device consists of two spraying units symmetrically arranged on both sides of the multi-layer photovoltaic (PV) tube piles on the main body of the fixture. The spraying units are fixedly supported by ground piles 10, and guide rail units are fixedly installed on the upper ends of the ground piles 10. These guide rail units extend along the length of the PV tube piles and are adapted to the multiple sets of fixtures distributed at intervals within the PV tube pile transfer fixture. During the anti-corrosion spraying operation, the moving unit slides smoothly along the guide rail units, driving the spraying robot 11 to move synchronously along the axial direction of the PV tube pile. Simultaneously, the flipping unit in the aforementioned PV tube pile transfer fixture drives the PV tube pile to rotate smoothly circumferentially. The two work together to achieve anti-corrosion spraying without dead angles on the circumferential outer surface of the PV tube piles, meeting the collaborative operation requirements of layered batch transfer and batch spraying of PV tube piles. Furthermore, by adjusting the angle of the PV tube piles using the flipping unit, operators can perform welding operations on or around the sides of the fixture. The layered structure of the fixture also facilitates welding of the multi-layered PV tube piles separately, eliminating the need for an additional welding platform.

[0030] Please refer to this again. Figure 8The guide rail unit includes a guide seat 12 and an upper guide rail 13 and a lower guide rail 14 disposed on the guide seat 12. The guide rail unit adopts a combined structure of the upper guide rail 13 and the lower guide rail 14, which forms a bidirectional limiting and guiding structure for the moving unit, effectively improving the running stability of the moving unit during the sliding process along the guide rail unit, and providing stable structural support for subsequent continuous and uniform anti-corrosion spraying operations.

[0031] Specifically, the moving unit includes a mounting base 15 and a drive unit mounted on the mounting base 15. The mounting base 15 is L-shaped and includes a horizontal portion and a vertical portion. A slider 16 that cooperates with the upper guide rail 13 is provided on the horizontal portion of the mounting base 15, and a slider 2 17 that cooperates with the lower guide rail 14 is provided on the vertical portion of the mounting base 15. Based on the structural layout of the L-shaped mounting base 15, the moving unit forms limiting and guiding relationships with the aforementioned guide rail units from the top and side, respectively. Simultaneously, the sliding cooperation between slider 16 and the upper guide rail 13, and between slider 2 17 and the lower guide rail 14, effectively improves the smoothness of the moving unit's movement and ensures the stable and reliable movement of the painting robot 11.

[0032] Please refer to this again. Figure 9 The drive unit includes a second motor 18 and a drive gear 19 mounted on the output end of the second motor 18. The second motor 18 is fixed to the horizontal part of the mounting base 15. A rack 20 is also provided on the guide seat 12, and the rack 20 is arranged parallel to the upper guide rail 13. The drive gear 19 meshes with the rack 20. A driven gear 21 is also provided on the horizontal part of the mounting base 15, and the driven gear 21 meshes with the rack 20. During operation, the second motor 18 drives the drive gear 19 to rotate. The meshing transmission between the drive gear 19 and the rack 20 generates moving power, thereby driving the overall moving unit to move along the guide rail unit and moving the painting robot 11 smoothly. The driven gear 21 has no independent power input. It moves synchronously with the moving unit and is passively meshed with the rack 20, which can effectively compensate for the fit clearance in the single gear transmission and ensure the smooth operation of the moving unit.

[0033] The working principle of this invention is as follows: This invention is divided into loading and storage, transfer, welding, and coordinated anti-corrosion spraying processes, achieving multi-process collaboration, specifically: First, following the standard operating logic of loading layer by layer from bottom to top, the bottom layer of stable bearing foundation is formed by welding and fixing the crossbeam 3. Then, the crossbeam 4 is successively connected and installed on the bracket 5 of the column 1, and the multi-layer photovoltaic tube piles are placed layer by layer, so that each photovoltaic tube pile is stably erected between the two sets of rollers 2 of the corresponding flipping unit. Further, the U-shaped enclosure 9 set on the outside of the column 1 forms a lateral limit for the upper crossbeam 4 and photovoltaic tube piles. After loading, the self-propelled modular transport vehicle with its own lifting function is used to lift the vehicle body and stably support multiple sets of tooling bodies for overall transportation of photovoltaic tube piles. When it arrives at the work position of the photovoltaic tube pile spraying device, the self-propelled modular transport vehicle body is lowered and positioned, so that the tooling body is completely separated from the vehicle body and lands independently, directly using the tooling body as a fixed bearing platform for anti-corrosion spraying or conventional welding operations.

[0034] On the one hand, during the anti-corrosion spraying operation, the motor 8 of each flipping unit operates independently, driving the roller 2 to rotate continuously, thus maintaining the stable circumferential flipping of the photovoltaic tube pile. Simultaneously, the spraying units on both sides of the photovoltaic tube pile work synchronously. Motor 18 drives the active gear 19 to mesh with the rack 20, providing the power for the spraying robot 11 in the moving unit. The passive gear 21 follows and meshes with the rack 20. The moving unit, guided by the upper guide rail 13 and lower guide rail 14, drives the spraying robot 11 to move stably along the axial direction of the photovoltaic tube pile. Through the coordinated operation of the continuous circumferential flipping of the photovoltaic tube pile and the axial movement of the spraying robot 11, the anti-corrosion spraying operation on the outer circumferential surface of the multi-layer photovoltaic tube pile is completed without any blind spots. On the other hand, during conventional welding operations, the angle of the photovoltaic tube pile can be adjusted again using the flipping unit, eliminating the need for re-clamping and allowing direct welding operations.

[0035] After the above anti-corrosion spraying and welding operations are completed, the operation mode can be flexibly switched according to subsequent needs. The main body of the tooling can be lifted again by a self-propelled modular transport vehicle to transfer the photovoltaic pipe piles to the next process, or the main body of the tooling can be placed independently for a long time to realize the layered storage of photovoltaic pipe piles. During the unloading operation, the operation logic from top to bottom is followed. The upper photovoltaic pipe piles are lifted and removed in sequence, and the corresponding crossbeam 4 is disassembled to complete the unloading operation layer by layer.

[0036] In summary, this invention, considering both the production and usage conditions of photovoltaic tube piles, innovates by integrating a transport, welding, and anti-corrosion spraying structure. This breaks away from the limitations of traditional single-transportation tooling and effectively solves the problems of low production efficiency caused by the disconnect between transport, spraying, and welding processes in existing technologies, which necessitates additional flipping and welding fixtures. The bottom crossbeam of the main tooling structure is stable and reliable, while the upper crossbeam adopts a disassembly and overlap design, enabling layered stacking and disassembly of photovoltaic tube piles, while facilitating layered welding and spraying operations. Furthermore, it works in conjunction with a transport vehicle with built-in lifting capabilities to effectively load and unload the tooling. The main body can be placed independently and has both transportation and storage functions. At the same time, the invention integrates an independently driveable flipping unit on the main body of the tooling, which directly drives the photovoltaic pile to rotate circumferentially. This is suitable for spraying robots to achieve spraying without dead angles. When used with a spraying device, the photovoltaic pile is driven by guide rails and gear racks. By utilizing the coordinated action of the circumferential rotation of the photovoltaic pile on the tooling body and the axial movement of the spraying robot along the photovoltaic pile, the photovoltaic pile can be sprayed with anti-corrosion coating without dead angles. It can also adjust the angle of the photovoltaic pile to facilitate welding operations, fully meeting the needs of large-scale and continuous production operations of offshore photovoltaic piles.
