Description

Technical Field

[0001] This utility model relates to the field of power transmission tower processing technology, and in particular to a dual-station rotary welding platform for tower components. Background Technology

[0002] Welding and grinding are two crucial steps in the manufacturing process of iron tower components. Traditional welding and grinding operations are usually completed manually or by automated equipment at a single workstation, which has the following shortcomings:

[0003] Traditional work methods typically employ a fixed-station sequential operation, where all welding of a single component is completed first, and then the work is moved to another station for weld grinding. This single-line process has a significant efficiency bottleneck, as the grinding equipment is idle when the welding equipment is working, and vice versa. At the same time, although multi-station platforms exist in existing technologies, they generally lack process coordination capabilities, making it difficult to achieve simultaneous welding and grinding operations, resulting in insufficient processing efficiency.

[0004] To address the aforementioned problems, this utility model document proposes a dual-station rotary welding platform for iron tower components. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the separation of grinding and welding processes in the welding of iron tower components, which easily leads to the equipment being idle alternately, and the difficulty of multi-station platforms operating synchronously, resulting in low processing efficiency. Therefore, a dual-station rotary welding platform for iron tower components is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dual-station rotary welding platform for iron tower components includes:

[0008] A base, wherein a connecting column is fixedly installed on the top of the base, a connecting plate is fixedly installed on the top of the connecting column, and a fixing frame is fixedly inserted through the inside of the connecting plate;

[0009] Two sliding seats are slidably installed within the fixed frame;

[0010] Two multi-axis robotic arms are fixedly mounted on the bottom of two sliding seats;

[0011] The welding head and the grinding head are respectively located at the ends of the two multi-axis robotic arms;

[0012] A rotating plate is fitted onto the outer wall of the connecting column and is rotatably connected to the top of the base via a rotating shaft;

[0013] Two rotating seats are rotatably mounted on top of the rotating plate for placing the tower components to be processed;

[0014] The rotating assembly includes a first rotating mechanism and a second rotating mechanism, wherein the first rotating mechanism is used to drive the rotating plate to rotate, and the second rotating mechanism is used to drive the two rotating seats to rotate.

[0015] Drive components are used to drive the movement of the sliding block and the multi-axis robotic arm;

[0016] The first rotating mechanism drives the rotating plate to rotate 180 degrees to exchange the positions of the two workstations, the second rotating mechanism drives the rotating seat to rotate to adjust the component angle, and the driving assembly drives the welding head and the grinding head to move, so that welding and grinding can be carried out synchronously on the two workstations.

[0017] In one possible design, the first rotating mechanism includes a worm gear fixedly sleeved on the outer wall of the rotating shaft of the rotating plate, a worm rotatably mounted on the top of the base and meshing with the worm gear, and a first motor fixedly mounted on the top of the base and connected to the worm.

[0018] In one possible design, the second rotating mechanism includes two second synchronous pulleys rotatably mounted on the top of the rotating plate, two gears coaxially fixed to the second synchronous pulleys and meshing with each other, two first synchronous pulleys fixedly sleeved on the outer wall of the bottom shaft of the rotating seat, a synchronous belt connecting the second synchronous pulleys to the adjacent first synchronous pulleys, and a second motor fixedly mounted on the top of the rotating plate and connected to one of the second synchronous pulleys.

[0019] In one possible design, the drive assembly includes a double-threaded screw rotatably mounted within a fixed frame. The double-threaded screw has two threaded segments with opposite threads, and two sliding seats are threadedly connected to the two threaded segments respectively. A motor drives the double-threaded screw to rotate to achieve synchronous movement of the sliding seats.

[0020] In one possible design, the drive assembly further includes two drive screws rotatably mounted inside the slide seat, a slider slidably connected to the bottom of the slide seat and threadedly connected to the drive screws, and a multi-axis robotic arm fixedly mounted to the bottom of the slider.

[0021] In one possible design, the welding head and the grinding head are angled via a drive bracket at the end of a multi-axis robotic arm.

[0022] In one possible design, positioning posts are fixedly installed on the top of both rotating seats to mate with positioning holes on the tower components to be processed.

[0023] In one possible design, a control cabinet is also included, which is fixedly mounted on one side of the base for controlling the operation of the equipment.

[0024] In one possible design, the grinding head is a cone and is driven to rotate by a motor.

[0025] In this application, during use, the operator can place the tower components to be processed onto two rotating seats respectively. During placement, ensure that the positioning pins penetrate the pre-set positioning holes on the corresponding tower components, thereby ensuring that the tower components can be stably placed on the corresponding rotating seats.

[0026] After placement, start the equipment. When the drive assembly is working, the double-threaded screw inside the fixed frame rotates under the drive of the motor. Since the two sliding seats are located on the threaded sections of the double-threaded screw with opposite thread directions, the rotation of the double-threaded screw allows the two sliding seats to move synchronously towards or away from each other within the fixed frame, thereby driving the welding head and grinding head closer to or further away from the workstation in the horizontal X-axis direction. The slider at the bottom of each sliding seat, driven by the corresponding drive screw, can move along the sliding seat, driving the multi-axis robotic arm to move in the other horizontal Y-axis direction. The multi-axis robotic arm itself can also perform movements, achieving fine adjustment of the welding head and grinding head in the vertical Z-axis direction and in terms of angle, to adapt to the processing needs of different positions on the tower components.

[0027] During the processing, operators should first grind the areas of the tower components to be welded to remove adhering oil, rust, and other impurities. This ensures a better welding result before subsequent welding. During operation, a grinding head located above one workstation begins work, moving and adjusting via a connected multi-axis robotic arm to grind and clean the welded joints of the tower components at that workstation. Simultaneously, if a cleaned tower component is present at another workstation, the welding head will also move accordingly and weld the corresponding joint. As the processing continues, welding and grinding operations can be performed concurrently at both workstations.

[0028] When welding is completed at one station and grinding at another, the first rotating mechanism is activated. The output shaft of the first motor drives the worm gear to rotate, which in turn drives the meshing worm wheel to rotate. The worm wheel drives the rotating plate to rotate around the connecting column relative to the base. The rotation of the rotating plate causes the station where welding was performed to rotate to the position below the grinding head, and the station where grinding was performed to rotate to the position below the welding head. During this process, the worm gear mechanism ensures that the rotating plate remains stable after it has rotated into position.

[0029] Next, the second rotating mechanism is activated. The output shaft of the second motor drives a second synchronous pulley connected to it to rotate. Since the two second synchronous pulleys are linked by meshing gears, they rotate synchronously in opposite directions. Each second synchronous pulley drives the adjacent first synchronous pulley to rotate via a synchronous belt. The first synchronous pulley drives the corresponding rotating seat to rotate relative to the rotating plate. The synchronous rotation of the two rotating seats, in conjunction with the movement of adjacent multi-axis robotic arms, allows the iron tower components fixed on them to be adjusted in real time to a suitable angle for welding or grinding.

[0030] Following the above procedures, welding and grinding processes can be performed alternately and continuously at the two workstations. Operators can remove finished tower components from the completed workstation and place new components to be processed for a new round of grinding and cleaning, after which the equipment continues to run. The entire process is controlled via a control cabinet.

[0031] Beneficial effects: The dual-station rotary welding platform for iron tower components described in this utility model, through its dual-station design, allows the platform to simultaneously support the processing of two iron tower components. Once the component at one station has been welded or ground, the platform can quickly rotate to the other station for further processing, eliminating equipment waiting time, significantly shortening the single-piece processing cycle, and thus greatly improving production efficiency.

[0032] In this invention, a dual-station rotary welding platform for tower components is provided. The platform is equipped with a multi-axis robotic arm, a welding head, and a grinding head, enabling precise machining of tower components. The horizontal movement of the robotic arm, linked by a double-threaded screw, combined with the vertical displacement of the slider and the angle adjustment of the multi-axis robotic arm, allows the welding head and grinding head to accurately complete three-dimensional positioning and adapt to the curved surface of the component. This ensures high-quality completion of welding and grinding operations and improves the overall quality of the tower components.

[0033] In this utility model, the dual-station rotary welding platform for iron tower components drives two rotating seats to rotate in opposite directions through a dual synchronous wheel system with gear meshing. This allows components at different stations to adjust their angles independently, optimizing the weld orientation without manual intervention. Combined with the multi-axis robotic arm, it ensures accurate orientation adjustment of the weld during grinding and welding processes.

[0034] In this utility model, the dual-station rotary welding platform for iron tower components is equipped with a control cabinet that enables centralized control of the equipment. Operators can easily complete operations such as starting, stopping, and setting parameters through the control cabinet, which improves the convenience and safety of operation.

[0035] In this invention, the welding platform supports the simultaneous processing of two components through a dual-station design, and the switching of station rotation can eliminate equipment waiting time; the multi-axis robotic arm achieves three-dimensional precise positioning of the welding head and grinding head through a double-threaded screw and slider, and the gear meshing system drives the rotating seat to automatically adjust the component angle, effectively ensuring the welding and grinding quality; the equipment is centrally scheduled through the control cabinet, which simplifies the operation process and improves the safety and continuity of the operation.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0043] In one embodiment: Refer to Figure 1-5 A welding platform includes: a base 1, a rotating plate 2, a rotating seat 3, a rotating assembly, a driving assembly, and related supporting components.

[0044] In this embodiment, the base 1 serves as the supporting foundation for the entire platform, with a connecting column 6 fixedly installed on its top. A connecting plate 4 is fixedly connected to the top of the connecting column 6. A fixing frame 5 is fixedly installed through the connecting plate 4, located near the top of the connecting plate 4. Two sliding seats 15 are slidably installed within the fixing frame 5. A multi-axis robotic arm 19 is installed at the bottom of each sliding seat 15, and a welding head 20 and a grinding head 21 are respectively installed at the bottom of the multi-axis robotic arm 19. The welding head 20 is used for welding the tower components to be processed, and the grinding head 21 is used for grinding and cleaning the joints of the welded components.

[0045] In this embodiment, the rotating plate 2 is sleeved on the outer wall of the connecting column 6 and is rotatably connected to the top of the base 1 via a rotating shaft. Two rotating seats 3 are rotatably provided on the top of the rotating plate 2, and the two rotating seats 3 are located near the two ends of the rotating plate 2, respectively, for placing the tower components to be processed.

[0046] In this embodiment, the rotating assembly includes a first rotating mechanism and a second rotating mechanism. The first rotating mechanism is used to drive the rotation of the rotating plate 2. Specifically, the first rotating mechanism includes a worm gear 9 fixedly sleeved on the outer wall of the rotating shaft of the rotating plate 2, a worm 7 rotatably mounted on the top of the base 1 via a bracket, and a first motor 8 fixedly mounted on the top of the base 1. One end of the output shaft of the first motor 8 is fixedly connected to one end of the worm 7, and the worm 7 meshes with the worm gear 9. When the first motor 8 starts, it drives the worm 7 to rotate. The worm 7 drives the rotating plate 2 to rotate stably through meshing with the worm gear 9, thereby realizing the interchange of the positions of the tower components to be processed at the two workstations.

[0047] In this embodiment, the second rotating mechanism is used to drive the synchronous rotation of the two rotating seats 3. Specifically, the second rotating mechanism includes two second synchronous wheels 12 rotatably mounted on the top of the rotating plate 2. Each of the two second synchronous wheels 12 is equipped with a gear 13, which is fixedly connected to the corresponding second synchronous wheel 12 via the same rotating shaft. The two gears 13 mesh with each other, allowing the two second synchronous wheels 12 to rotate synchronously in opposite directions. First synchronous wheels 11 are fixedly sleeved on the outer wall of the bottom rotating shaft of each of the two rotating seats 3. The two second synchronous wheels 12 are connected to the adjacent first synchronous wheels 11 via synchronous belt transmission. A second motor 14 is fixedly mounted on the top of the rotating plate 2 via a bracket. One end of the output shaft of the second motor 14 is fixedly connected to one end of the rotating shaft of one of the second synchronous wheels 12. When the second motor 14 starts, it drives one of the second synchronous wheels 12 to rotate. Through synchronous belt transmission and gear 13 meshing, the two rotating seats 3 rotate synchronously, thereby driving the tower components to be processed placed on the rotating seats 3 to rotate, thus meeting the requirements for welding and grinding.

[0048] In this embodiment, the drive assembly is used to drive the welding head 20 and the grinding head 21 to move accordingly, and is divided into two parts. The first part is used to drive the two sliding seats 15 to move synchronously closer or further away within the fixed frame 5. Specifically, a double-threaded screw 16 is rotatably installed within the fixed frame 5. The double-threaded screw 16 is driven by a motor located on one side of the fixed frame 5. The double-threaded screw 16 rotates through the connecting plate 4. The two sliding seats 15 are located on both sides of the connecting plate 4 and are threadedly connected to the double-threaded screw 16. The two sliding seats 15 are located on the two opposite thread segments of the double-threaded screw 16. When the motor drives the double-threaded screw 16 to rotate, the two sliding seats 15 will move synchronously closer or further away along the double-threaded screw 16, thereby adjusting the horizontal position of the welding head 20 and the grinding head 21.

[0049] Furthermore, in this embodiment, the second part is used to drive the multi-axis robotic arm 19 to move in the vertical direction. Specifically, a drive screw 18 is rotatably installed inside each of the two sliding seats 15, and both drive screws 18 are driven by a motor located on one side of the corresponding sliding seat 15. A slider 17 is slidably connected to the bottom of each of the two sliding seats 15, and both sliders 17 are threadedly connected to the corresponding drive screw 18. The two multi-axis robotic arms 19 are fixedly connected to the bottom of the corresponding sliders 17. When the motor drives the drive screw 18 to rotate, the slider 17 moves vertically along the drive screw 18, thereby driving the multi-axis robotic arm 19 and the welding head 20 or grinding head 21 to move vertically.

[0050] In this embodiment, both the welding head 20 and the grinding head 21 correspond to the adjacent rotating seat 3, and their angles are adjusted by a drive bracket at the end of the corresponding multi-axis robotic arm 19. The multi-axis robotic arm 19 is the same as that in patent CN222934627U. The welding head 20 is the same as that in patent CN222931977U. Meanwhile, the grinding head 21 is a cone, driven by a corresponding motor to ensure effective grinding of the joints of the tower components to be processed.

[0051] This application can be used in the field of power tower processing technology, or in other fields applicable to this application.

[0052] In another embodiment: Reference Figure 2 , 4 A dual-station rotary welding platform for iron tower components is applied to the field of power iron tower processing technology.

[0053] In this embodiment, a control cabinet 10 is fixedly installed on one side of the base 1. The control cabinet 10 is used to operate the equipment. The operator can set relevant parameters through the control cabinet 10 to control the start, stop, and speed of the first motor 8, the second motor 14, and each motor in the drive assembly, thereby achieving precise control of the welding and grinding process.

[0054] In this embodiment, a positioning column is fixedly installed on the top of the rotating seat 3. The positioning column cooperates with the pre-set positioning hole on the iron tower component to be processed, which can ensure that the component can be stably placed on the rotating seat 3 and avoid displacement during rotation or processing.

[0055] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 8, the second motor 14, and the various corresponding motors are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0056] The working principle and usage process of this technical solution are as follows: During use, the operator can place the tower components to be processed onto the two rotating seats 3 respectively. When placing them, ensure that the positioning pins pass through the pre-set positioning holes on the corresponding tower components, and ensure that the tower components can be stably placed on the corresponding rotating seats 3.

[0057] After placement, the equipment is started. When the drive assembly is working, the double-threaded screw 16 within the fixed frame 5 rotates under the drive of the motor. Since the two sliding seats 15 are located on the threaded sections of the double-threaded screw 16 with opposite thread directions, the rotation of the double-threaded screw 16 allows the two sliding seats 15 to move synchronously towards or away from each other within the fixed frame 5, thereby driving the welding head 20 and the grinding head 21 to move closer to or away from the workstation along the horizontal X-axis. The slider 17 at the bottom of each sliding seat 15, driven by the corresponding drive screw 18, can move along the sliding seat 15, thereby driving the multi-axis robotic arm 19 to move along the other horizontal Y-axis. The multi-axis robotic arm 19 itself can also move, enabling fine adjustment of the welding head 20 and the grinding head 21 along the vertical Z-axis and in terms of angle, to adapt to the processing requirements of different positions of the tower components.

[0058] During the processing, operators should first grind the areas of the tower components to be welded to remove attached oil, rust, and other impurities before proceeding with welding, thus ensuring a better welding effect. During operation, the grinding head 21, located above one workstation, begins working, moving and adjusting via the connected multi-axis robotic arm 19 to grind and clean the welded joints of the tower components at that workstation. Simultaneously, if a cleaned tower component exists at another workstation, the welding head 20 will also move accordingly and weld the corresponding joint. As the processing continues, welding and grinding operations can be performed simultaneously at both workstations.

[0059] When welding is completed at one station and grinding at another, the first rotating mechanism is activated. The output shaft of the first motor 8 drives the worm gear 7 to rotate, which in turn drives the meshing worm wheel 9 to rotate. The worm wheel 9 drives the rotating plate 2 to rotate around the connecting column 6 relative to the base 1. The rotating plate 2 rotates 180 degrees, so that the station where welding was originally performed is now below the grinding head 21, and the station where grinding was originally performed is now below the welding head 20. During this process, the worm wheel 9 and worm gear 7 mechanism ensures that the rotating plate 2 remains stable after it has rotated into position.

[0060] Next, the second rotating mechanism is activated. The output shaft of the second motor 14 drives a second synchronous pulley 12 connected to it to rotate. Since the two second synchronous pulleys 12 are linked by meshing gears 13, they achieve synchronous and opposite rotation. Each second synchronous pulley 12 drives the adjacent first synchronous pulley 11 to rotate via a synchronous belt. The first synchronous pulley 11 drives the corresponding rotating seat 3 to rotate relative to the rotating plate 2. The synchronous rotation of the two rotating seats 3, in conjunction with the movement of the adjacent multi-axis robotic arms 19, allows the iron tower components fixed on them to be adjusted in real time to a suitable angle for welding or grinding.

[0061] Following the above procedures, welding and grinding processes can be performed alternately and continuously at the two workstations. Operators can remove finished tower components from the completed workstation and place new components to be processed for a new round of grinding and cleaning, after which the equipment continues to run. The entire process is controlled via control cabinet 10.

[0062] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0063] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
