Description

Technical Field

[0001] This invention relates to the field of tower welding technology, specifically to a power transmission tower welding device. Background Technology

[0002] As a key supporting structure for power transmission networks, the welding quality of the tower legs directly affects the stability and safety of the overall structure. Tower legs are typically welded from stiffening plates and a base plate, with weld seams including straight sections and curved corners. If weld slag generated during the welding process is not cleaned thoroughly and promptly, it will directly affect weld quality inspection and may even conceal defects such as incomplete penetration and porosity, creating safety hazards.

[0003] Currently, in the manufacturing process of transmission towers, post-weld cleaning relies partially on manual operation, which is inefficient and inconsistent in cleaning results. However, some automated equipment has been developed for weld slag removal, such as the welding cleaning device described in patent number 202411456002.1. Such devices can typically effectively handle straight-line welds, removing weld slag through a combination of mechanical scraping and negative pressure absorption.

[0004] However, in actual tower foot welding, the weld connecting the stiffening plate and the base plate is not entirely straight; there are continuous arc-shaped welds at corners. The prior art solution represented by patent 202411456002.1 exhibits limitations in dealing with such arc-shaped welds. Its cleaning components are typically designed for linear movement or simple fixed-angle cleaning, making it difficult to closely follow the curvature changes of the arc-shaped weld. Forced cleaning may result in incomplete removal of weld slag at the arc-shaped weld, leaving residue. Alternatively, the moving mechanism designed to adapt to the curve may lack sufficient stability and adaptability, failing to maintain a stable cleaning force during the cleaning process, posing a dual risk of over-cleaning and damaging the weld surface or under-cleaning. This insufficient ability to clean complex-shaped welds restricts the overall efficiency improvement of automated welding equipment, meaning that after cleaning straight welds, manual assistance may still be needed to finish the arc-shaped sections, affecting the continuity and efficiency of the production process.

[0005] Therefore, existing transmission tower welding equipment has room for improvement in the post-weld cleaning process, especially in how to effectively, automatically, and adaptively clean continuous welds that combine straight and curved lines. It is necessary to design a cleaning mechanism that can seamlessly switch and adaptively conform to different weld trajectories to achieve full-process, all-type weld slag cleaning automation.

[0006] Therefore, we propose a welding equipment for power transmission towers. Summary of the Invention

[0007] One technical problem this application aims to solve is that existing transmission tower welding equipment has shortcomings in the post-weld cleaning process, particularly in effectively, automatically, and adaptively cleaning continuous welds that combine straight and curved lines. It is necessary to design a cleaning mechanism that can seamlessly switch and adaptively conform to different weld trajectories to achieve full-process, all-type weld slag cleaning automation.

[0008] To address the aforementioned technical problems, this application provides a transmission tower welding device, including an operating platform, a robotic arm, a rotating connector, and a slag-cleaning assembly. One end of the rotating connector is connected to the operating platform, and the other end is connected to the slag-cleaning assembly. The robotic arm is positioned on one side of the operating platform. The slag-cleaning assembly is equipped with a clamping block for fixing the tower foot components. The slag-cleaning assembly also includes a slag-cleaning mechanism, which is equipped with a slag-suction component, a slag-cleaning block, a torsion spring, and a compression spring for cleaning the weld slag from the straight and curved welds after the tower foot components have been welded.

[0009] In some embodiments, the clamping and cleaning assembly is further provided with a vertically fixed support beam and a connecting beam. The support beam and the connecting beam form a frame as a whole. A clamping block is provided on the top surface of the support beam, and a rotating handle is provided at the tail end of the support beam. Rotating the rotating handle clockwise causes the clamping block to move forward to fix the tower foot component. A connecting sleeve is provided on the connecting beam to fix the cleaning mechanism.

[0010] In some embodiments, the slag removal mechanism further includes a housing, a connecting block disposed in a space within the housing, an electric push rod connected to the connecting block, a slag suction component rotatably connected to the connecting block, a negative pressure unit disposed on top of the slag suction component, and a slag removal block disposed below the slag suction component.

[0011] In some embodiments, the slag removal block is fixedly connected to the connecting rod 2. The inner side of the connecting rod 2 is provided with a bevel to facilitate the absorption of welding slag. The tail end of the connecting rod 2 is provided with a tail component 2, and the tail component 2 is provided with a connecting hole 1.

[0012] In some embodiments, a connecting shaft 2 is provided inside the connecting hole 1, and a torsion spring is provided inside the connecting shaft 2. The torsion spring is in a pre-tightened state to restrict the connecting rod 2 from rotating outward.

[0013] In some embodiments, a compression spring is provided near the tail component 2 on the connecting rod 2. One end of the compression spring is fixedly connected to the connecting rod 2, and the other end of the compression spring is fixedly connected to the side wall of the intermediate wall located in the middle of the space 1.

[0014] In some embodiments, a second suction hole is provided on the inner side of the plane in contact with the second connecting rod of the suction component, and a first suction hole is provided in front of the suction component above the cleaning block.

[0015] In some embodiments, the tail end of the slag suction component is provided with a tail component 1, which is rotatably connected to the connecting block.

[0016] In some embodiments, a groove 1 is provided on the surface of the slag suction component near the connecting rod 2, and a groove 2 is provided between the two groove 1s. A connecting rod is provided in the groove 2, one end of the connecting rod is fixedly connected to the connecting rod 2, a connecting plate is provided on the lower side of the connecting rod, and side plates are fixedly provided on both sides of the connecting plate. The side plates are rotatably connected to the connecting rod 1. A connecting shaft 1 is provided on the outer side of the connecting rod 1, and the connecting shaft 1 is fixedly connected to the bottom surface of the moving plate. A cover plate is provided on the lower side of the moving plate to close the groove 2.

[0017] In some embodiments, a spring is fixedly provided on the inner side of the connecting plate, and the other side of the spring is fixedly connected to the side wall of the groove. A connecting rod passes through the groove and the first groove and is fixedly connected to the movable plate.

[0018] This invention has at least the following beneficial effects:

[0019] 1. The tower leg is firmly fixed by the clamping block in the slag removal assembly to prevent displacement or loosening during welding and ensure the accuracy of the welding position. After welding is completed, the slag removal mechanism is immediately activated. The electric actuator pushes the connecting block to move the slag removal block forward, directly contacting the weld and scraping off the weld slag. The slag removal block is designed to handle both straight and curved welds at the same time. When encountering changes in weld shape, the torsion spring and compression spring work together to make the slag removal block move along the curved path, ensuring that the weld slag is completely removed.

[0020] 2. The slag suction unit works in conjunction with the negative pressure machine to suck up the scraped welding slag through the suction hole and collect it inside, reducing welding slag scattering and environmental pollution. During the cleaning of the arc weld, the rotation of the connecting rod two will drive the internal mechanism to automatically close the second suction hole, leaving only the first suction hole working, thereby reducing energy consumption. The entire slag cleaning process does not require manual intervention, reducing the labor intensity of operators and avoiding weld damage that may be caused by traditional cleaning methods. The structural design of the equipment allows the clamping and slag cleaning actions to be carried out in a continuous manner, reducing process changeover time and improving the continuity and stability of welding operations.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1, see Figure 1-11This invention provides a technical solution: a transmission tower welding device, including an operating platform 100, a robotic arm 200, a rotating connector 300, and a slag-cleaning assembly 400. One end of the rotating connector 300 is connected to the operating platform 100, and the other end is connected to the slag-cleaning assembly 400. The robotic arm 200 is disposed on one side of the operating platform 100. The slag-cleaning assembly 400 is provided with a clamping block 401 for fixing the tower foot component 500. The slag-cleaning assembly 400 is also provided with a slag-cleaning mechanism 406. The slag-cleaning mechanism 406 is provided with a slag-suction component 4062, a slag-cleaning block 4067, a torsion spring 40676, and a compression spring 40677 for cleaning the weld slag from the straight weld and the arc weld after the tower foot component 500 is welded.

[0035] Specifically, the operating platform 100 serves as the basic support structure of the equipment, providing a stable working platform. The robotic arm 200 is positioned on one side of the operating platform 100 and is responsible for performing the welding tasks of the tower leg component 500. A rotating connector 300 is connected at one end to the operating platform 100 and at the other end to the clamping and cleaning assembly 400, allowing the clamping and cleaning assembly 400 to rotate. This adjusts the position and angle of the tower leg component 500, assisting the robotic arm 200 in welding from different angles.

[0036] The slag-cleaning assembly 400 is designed to fix the tower foot 500 and clean the weld slag on the same assembly. The clamping block 401 is mounted on the support beam 403 and, driven by rotating the handle 402, firmly clamps the four ends of the tower foot 500, preventing workpiece displacement during welding. The slag-cleaning mechanism 406 is mounted on the connecting beam 404 and is specifically designed to clean the weld slag generated after welding. The slag-cleaning mechanism 406 includes a slag-cleaning block 4067 for scraping off weld slag, a slag-absorbing component 4062 for absorbing weld slag, and torsion springs 40676 and compression springs 40677 providing elastic force to adapt to the weld shape.

[0037] The working principle of the slag removal mechanism 406 involves the synergistic effect of mechanical motion and elastic elements. The electric actuator 4068 pushes the connecting block 4063, causing the slag removal block 4067 to move forward via the connecting rod 40671. When cleaning straight welds, the torsion spring 40676 and the compression spring 40677 are in a pre-tensioned state, restricting the outward rotation of the connecting rod 40671 and maintaining the stable position of the slag removal block 4067 to scrape off the weld slag. When the slag removal block 4067 contacts the connection point between the straight weld and the arc weld, the slag removal block 4067 needs to move along the arc path. At this time, the tail part 40673 of the connecting rod 40671 will rotate outward around the connecting shaft 40675. The torsion spring 40676 generates a torque to resist the rotation, while the compression spring 40677 changes from a compressed state to a stretched state, providing a restoring force. The superposition of these two forces enables the slag removal block 4067 to adaptively conform to the curvature of the arc weld and continue to scrape off the weld slag, thereby achieving comprehensive cleaning of complex welds.

[0038] The slag suction component 4062 is designed to work in conjunction with the negative pressure unit 4064, sucking up scraped welding slag through suction holes 40621 and 40622. During the cleaning of the arc weld, the rotation of connecting rod 40671 drives internal mechanisms such as connecting rod 40626 to move, squeezing connecting plate 40627, which in turn causes moving plate 40632 to rise via connecting rod 40628, blocking suction hole 40622. In this way, only suction hole 40621 remains operational, sucking up welding slag from the arc weld, reducing energy consumption.

[0039] The advantages of this design include improved overall welding efficiency. Welding and cleaning processes are continuous, requiring no equipment changes or manual intervention, thus reducing process changeover time. The slag removal block 4067 can handle both straight and curved welds, ensuring thorough slag removal and avoiding the problem of incomplete cleaning of curved welds by traditional cleaning equipment. The rotating connector 300 provides flexibility in adjusting the workpiece angle, enabling the robotic arm 200 to more effectively perform multi-position welding. The integrated design of the slag removal clamping assembly 400 simplifies the equipment structure and reduces operational complexity. Simultaneously, the slag suction component 4062 uses negative pressure to extract slag, maintaining a clean working environment and reducing contamination. Overall, this equipment achieves full automation from welding fixation to slag removal, improving production continuity and welding quality consistency.

[0040] Example 2, see Figure 1-11 The clamping and cleaning assembly 400 is also provided with a vertically fixed support beam 403 and a connecting beam 404. The support beam 403 and the connecting beam 404 form a frame. The top surface of the support beam 403 is provided with a clamping block 401. The tail end of the support beam 403 is provided with a rotating handle 402. Rotating the rotating handle 402 clockwise causes the clamping block 401 to move forward to fix the tower foot component 500. The connecting beam 404 is provided with a connecting sleeve 405 to fix the cleaning mechanism 406.

[0041] Specifically, the support beam 403 and the connecting beam 404 are vertically fixed to form a rigid frame. Within this frame, the support beam 403 primarily bears the clamping function, with its top surface featuring a clamping block 401 for direct contact and positioning of the tower foot component 500. The mechanical transmission principle is embodied in the rotating handle 402 at the tail end of the support beam 403. The operator rotates the handle 402 clockwise, converting the rotational motion into linear motion through an internal transmission mechanism (such as a lead screw or rack and pinion), driving the clamping block 401 forward and thus clamping and fixing the tower foot component 500. The connecting beam 404 primarily bears the cleaning function, with a connecting sleeve 405 serving as a standardized installation interface for fixing the slag cleaning mechanism 406, enabling a detachable connection between the cleaning module and the clamping frame.

[0042] The purpose of this design is firstly to integrate the workpiece fixing function with the subsequent cleaning function within a unified rigid frame, ensuring that the tower leg component 500 remains on the same stable reference platform from the start of welding to the end of cleaning, reducing positioning errors and time consumption caused by workpiece transfer or reclamping. Secondly, manual clamping via rotating the handle 402 provides a reliable and intuitive locking method, ensuring that the workpiece does not move during welding. Finally, the design of the connecting beam 404 and connecting sleeve 405 provides a clear installation position and support for the slag cleaning mechanism 406, guaranteeing the stability of the actuators during cleaning operations.

[0043] The frame, composed of support beam 403 and connecting beam 404, possesses good structural rigidity, resisting vibrations and forces generated during welding and cleaning, providing a stable foundation for the entire process. The clamping block 401 is driven by a simple rotating handle 402 for linear clamping, offering easy operation and controllable clamping force, effectively securing the four ends of the tower leg component 500 and preventing deformation or displacement during welding. The slag removal mechanism 406 is mounted on the independent connecting beam 404 via a connecting sleeve 405, achieving both functional module separation and integration. This ensures the cleaning mechanism has an independent and stable mounting base, while also making maintenance or replacement more convenient without affecting the clamping components. The entire clamping and slag removal assembly 400 has a compact structure and high space utilization. As a single module, it is connected to the operating table 100 via a rotating connector 300, facilitating station rotation and angle adjustment. This integrated design simplifies the operation process; welding and cleaning can be completed after a single workpiece clamping, improving operational continuity and overall efficiency.

[0044] Example 3, see Figures 1-11 The slag cleaning mechanism 406 also includes a housing 4061, a connecting block 4063 disposed in a space 4069 inside the housing 4061, an electric push rod 4068 connected to the connecting block 4063, a slag suction component 4062 rotatably connected to the connecting block 4063, a negative pressure machine 4064 disposed on the top of the slag suction component 4062, and a slag cleaning block 4067 disposed below the slag suction component 4062.

[0045] The slag removal block 4067 is fixedly connected to the second connecting rod 40671. The inner side of the second connecting rod 40671 is provided with a bevel 40672 to facilitate the absorption of welding slag. The tail end of the second connecting rod 40671 is provided with a tail component 40673, and the tail component 40673 is provided with a first connecting hole 40674.

[0046] A connecting shaft 40675 is installed inside the connecting hole 40674, and a torsion spring 40676 is installed inside the connecting shaft 40675. The torsion spring 40676 is in a pre-tightened state to restrict the connecting rod 40671 from rotating outward.

[0047] A compression spring 40677 is provided near the tail component 40673 on the connecting rod 2 40671. One end of the compression spring 40677 is fixedly connected to the connecting rod 2 40671, and the other end of the compression spring 40677 is fixedly connected to the side wall of the intermediate wall 40690 located in the middle of the space 1 4069.

[0048] Specifically, the outer shell 4061 constitutes the external protection and support structure of the mechanism, while its internal space 4069 provides accommodation for various functional components. The electric actuator 4068 serves as the power source, its extension and retraction directly transmitting to the connecting block 4063, thereby driving the entire actuator to move linearly. The slag suction component 4062 is mounted on the connecting block 4063 via a rotatable connection, giving it a certain degree of freedom of movement. The negative pressure unit 4064 is located on top of the slag suction component 4062, responsible for generating negative pressure airflow. The slag cleaning block 4067, as the component directly performing the cleaning task, is connected to the internal motion mechanism via the connecting rod 40671.

[0049] The slag-cleaning block 4067 is fixedly connected to the connecting rod 40671, forming a rigid cleaning head. The inclined side 40672 designed on the inner side of the connecting rod 40671 is designed to guide the scraped welding slag to flow more easily to the slag-absorbing area. The tail component 40673 at the end of the connecting rod 40671 engages with the connecting shaft 40675 through the connecting hole 40674, enabling the connecting rod 40671 to rotate around the shaft. The torsion spring 40676 installed inside the connecting shaft 40675, in the pre-tensioned state, always provides a torque that forces the connecting rod 40671 to retract inward, which is the mechanical basis for limiting its stable posture under normal conditions or when cleaning straight welds. Meanwhile, a compression spring 40677, located on the connecting rod 40671 near the tail component 40673, has one end fixed to the connecting rod 40671 and the other end fixed to the intermediate wall 40690 of the space 4069. When the connecting rod 40671 is in its initial or linear motion state, the compression spring 40677 is in a compressed state, and its elastic force also acts on the connecting rod 40671. Together with the torque of the torsion spring 40676, they work to maintain the linear stability of the cleaning head.

[0050] The primary purpose of this design is to automate the cleaning process and adaptively track the weld shape. The electric actuator 4068 provides controllable linear power, ensuring the slag-removing block 4067 can advance stably and scrape away weld slag. The dual elastic constraints of the torsion spring 40676 and compression spring 40677 are designed to allow the slag-removing block 4067 to maintain a predetermined trajectory when encountering straight welds, while allowing it to overcome the elastic constraints and rotate under external resistance when cleaning curved welds, thus smoothly transitioning and conforming to the curved trajectory. The negative pressure unit 4064 at the top of the slag-absorbing component 4062 is designed to promptly absorb the scraped weld slag, while the inclined edge 40672 on the inner side of the connecting rod 40671 is designed to improve the guiding effect of the weld slag and increase absorption efficiency.

[0051] The linear motion driven by the electric actuator 4068 ensures the stability and controllability of the cleaning process. The combined application of torsion springs 40676 and compression springs 40677 provides stable and compliant adaptability, enabling the slag removal block 4067 to effectively handle the transition between straight and curved weld seams, avoiding jamming or incomplete cleaning problems that may occur with rigid structures. The slag removal block 4067 is connected to the internal mechanism via connecting rod 40671, making the transmission of cleaning force direct and reliable. Negative pressure absorption and mechanical scraping are carried out simultaneously, helping to keep the working surface clean and prevent secondary contamination. The entire mechanism is integrated into the housing 4061, with a compact structure, and is easy to install on the clamping slag removal assembly 400 via connecting sleeve 405, realizing the automation and integration of the post-weld cleaning process.

[0052] Example 4, see Figures 1-11 The inner side of the plane where the slag suction component 4062 contacts the connecting rod 40671 is provided with a slag suction hole 40622, and the front of the slag suction component 4062 is provided with a slag suction hole 40621 above the slag cleaning block 4067.

[0053] The tail end of the slag suction component 4062 is provided with a tail component 40623, which is rotatably connected to the connecting block 4063.

[0054] The slag suction component 4062 has a groove 40624 on its surface near the second connecting rod 40671. A second groove 40625 is provided between the two grooves 40624. A connecting rod 40626 is provided in the second groove 40625. One end of the connecting rod 40626 is fixedly connected to the second connecting rod 40671. A connecting plate 40627 is provided on the lower side of the connecting rod 40626. Side plates 40629 are fixedly provided on both sides of the connecting plate 40627. The side plates 40629 are rotatably connected to the first connecting rod 40628. A connecting shaft 40630 is provided on the outer side of the first connecting rod 40628. The first connecting shaft 40630 is fixedly connected to the bottom surface of the moving plate 40632. A cover plate 40633 is provided on the lower side of the moving plate 40632 to close the second groove 40625.

[0055] A spring 40631 is fixedly installed on the inner side of the connecting plate 40627. The other side of the spring 40631 is fixedly connected to the side wall of the groove 40625. The connecting rod 40628 passes through the groove 40625 and the groove 40624 and is fixedly connected to the movable plate 40632.

[0056] Specifically, the design principle of the slag suction component 4062 is based on the synergistic effect of negative pressure suction and mechanical linkage. The slag suction component 4062 is rotatably connected to the connecting block 4063 through its tail component 40623 at its tail end. This allows the slag suction component 4062 itself to rotate slightly around an axis to adapt to the angle changes that the slag cleaning block 4067 may make when cleaning welds of different shapes, thereby maintaining the rationality of the relative position between the slag suction port and the cleaning area.

[0057] The first suction hole 40621 is located in front of the suction component 4062 and above the cleaning block 4067. Its position is designed so that it is always aligned with the leading edge area where the cleaning block 4067 is scraping off the welding slag, allowing it to immediately pick up the freshly removed welding slag. The second suction hole 40622 is located on the inner side of the plane that contacts the second connecting rod 40671. This position allows it to effectively pick up the welding slag guided from the inner inclined side 40672 of the second connecting rod 40671, as well as small particles that may splash into this area during the cleaning process.

[0058] The internal mechanism is designed based on a mechanical feedback and adjustment mechanism. One end of the connecting rod 40626 is fixedly connected to the second connecting rod 40671, so any rotation or displacement of the second connecting rod 40671 is directly transmitted to the connecting rod 40626. When the slag removal block 4067 cleans the straight weld seam, the second connecting rod 40671 remains in a stable position, and the connecting rod 40626 does not drive the subsequent mechanism. The connecting plate 40627 is connected to the side wall of the second groove 40625 via a spring 40631. Under normal conditions, the elastic force of the spring 40631 keeps the entire mechanism in a default position.

[0059] The primary purpose of this design is to achieve efficient slag removal and on-demand energy distribution. Two slag-removing holes at different locations are designed to expand the effective removal range, covering the main working area of ​​the slag-cleaning block 4067 and its rear side areas, thereby increasing the slag collection rate per cleaning cycle. The rotatable connection between the slag-removing component 4062 and the connecting block 4063 allows it to adaptively adjust to the posture of the cleaning head, maintaining the optimal removal angle.

[0060] The core purpose of the internal linkage mechanism is to automatically adjust the suction function according to the cleaning conditions. When the slag removal block 4067 is performing straight cleaning, the mechanism does not operate, and slag suction holes 1 40621 and slag suction hole 2 40622 work simultaneously. When cleaning an arc weld, when connecting rod 2 40671 rotates outward, it pushes connecting plate 40627 through connecting rod 40626. The movement of connecting plate 40627 compresses spring 1 40631, and at the same time, it drives connecting rod 1 40628, which is rotatably connected to it, to move through side plates 40629 on both sides. The movement of connecting rod 1 40628 is ultimately converted into the upward movement of moving plate 40632, which is fixed to it through connecting shaft 1 40630. The rising moving plate 40632 will block the slag suction hole 2 40622 located on the inner side. The cover plate 40633 is there to close the slot 40625 when the moving plate 40632 is not raised, so as to ensure the integrity of the negative pressure air duct inside the slag suction component 4062.

[0061] The dual slag suction holes improve the comprehensiveness and efficiency of slag removal, reducing residue. The rotating connection of the slag suction component 4062 enhances the adaptability of the entire cleaning head to the workpiece contour. The internal mechanical linkage mechanism enables the automatic closure of some slag suction holes according to the cleaning path. In scenarios such as cleaning arc welds where the inner slag suction hole 40622 does not need to operate at full capacity, automatically closing this channel concentrates negative pressure resources on the main slag suction hole 40621, reducing unnecessary energy loss and demonstrating a unity of function and energy saving. The entire mechanism is triggered entirely by the cleaning action itself, requiring no additional sensors or electrical control signals, resulting in a simple and reliable structure.

[0062] Working process: First, the tower leg component 500 is welded. The tower leg component 500 is placed on the frame composed of the support beam 403 and the connecting beam 404. The rotating handle 402 is rotated so that the clamping block 401 clamps and fixes the four ends of the tower leg component 500. Then, the robotic arm 200 is used for welding. During the welding process, the rotating connector 300 is used to rotate and change the position and angle to assist the robotic arm 200 in welding.

[0063] After welding is completed, the electric actuator 4068 is activated, pushing the connecting block 4063 to move the slag removal block 4067 and the second connecting rod 40671 forward. The two slag removal blocks 4067 are precisely clamped on the weld between the stiffening plate and the base plate of the tower foot component 500. The slag removal blocks 4067 and the second connecting rod 40671 move forward to scrape off the welding slag. At this time, the negative pressure machine 4064 is activated, and the welding slag is sucked up and stored in the slag suction component 4062 through the first suction hole 40621 and the second suction hole 40622. During this process, the torsion spring 40676 and the compression spring 40677 are always in a pre-tensioned state to prevent the second connecting rod 40671 from rotating outward. When the slag removal block 4067 contacts the straight... When the line weld and the arc weld are connected, the electric actuator 4068 causes the slag removal block 4067 to continue forward. At this time, the slag removal block 4067 moves along the arc weld and scrapes off the welding slag. During this process, the tail part 40673 at the end of the connecting rod 40671 rotates outward around the connecting shaft 40675. It is resisted by the torque of the torsion spring 40676. At the same time, the outward rotation of the connecting rod 40671 drives the compression spring 40677 to change from a compressed state to a stretched state. The compression spring 40677 also generates a force to resist the outward rotation of the connecting rod 40671. The two effects are superimposed, causing the slag removal block 4067 at the end of the connecting rod 40671 to move along the arc weld.

[0064] When connecting rod 40671 rotates outward, connecting rod 40626, which is fixedly connected to connecting rod 40671, moves outward to contact and press connecting plate 40627. Connecting plate 40627 moves downward to press spring 40631. During this process, side plate 40629 moves with connecting plate 40627. At the same time, since side plate 40629 is rotatably connected to connecting rod 40628, connecting rod 40628 moves inward, causing moving plate 40632, which is fixedly connected to connecting shaft 40630 at the end of connecting rod 40628, to move upward and block slag suction hole 40622. Thus, only slag suction hole 40621, along with slag removal block 4067, sucks up welding slag along the arc weld. Slag suction hole 40622 is blocked to save energy, and the whole process ends.
