Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a welding device for iron accessories. Background Technology

[0002] In the construction of power transmission networks, power line accessories are core supporting components that ensure the safe and stable operation of lines. They are widely used in key aspects such as transmission towers, conductor erection, and substation facilities. Their structural strength and connection reliability directly determine the load-bearing capacity and service life of power lines, and have a significant impact on the adaptability of the power grid to extreme conditions such as wind, earthquake, and snow. Power line accessories are diverse, with core components including steel plate parts, spacers, and other functional accessories. Each type of component plays a unique and indispensable role in the power system.

[0003] Steel plates and spacers are the basic structural components of electric railway accessories. Steel plates are mostly made of high-strength carbon steel or alloy steel and are formed through processes such as cutting, bending, and welding. Their main functions are structural support and force transmission. Spacers are mainly used in the installation of multi-branch conductors. Their core function is to maintain a fixed spacing between the multi-branch conductors and prevent them from colliding, rubbing, or galloping under the influence of wind, electromagnetic forces, etc.

[0004] Since steel plate components are mostly basic structural parts of power railway accessories, their size and shape must match different tower structures and stress scenarios. Spacer bars, on the other hand, are mostly rod-type structures, requiring assembly from multiple metal components such as steel pipes and connectors. These components must be spliced ​​and welded to form a complete load-bearing frame. Therefore, steel plates and spacer bars need to be welded according to requirements to suit construction needs. However, traditional welding equipment cannot clean weld slag from the welded areas, especially when welding spacer bars, making it impossible to perform circumferential or full welding on circular spacer bars, resulting in unsatisfactory performance. Summary of the Invention

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0031] Please refer to Figure 1-3 A welding device for iron fittings includes a base 1 and a gantry frame 2 integral with the base 1. A guardrail 3 is provided on one side of the gantry frame 2. A spacer bar moving clamping device is provided between two guardrail bars 3. The two spacer bars can be moved horizontally towards the gantry frame 2 through the moving clamping device. A cylinder 7 is provided on the gantry frame 2. The output end of the cylinder 7 passes through the gantry frame 2 and is fixedly connected to a lifting platform 8. A welding machine 81 is fixed on the lifting platform 8. When the two spacer bars move to directly below the welding machine 81, they rotate together. The welding machine 81 performs circumferential welding on the rotating spacer bars.

[0032] In use, firstly, the two spacer bars to be welded are symmetrically installed on the movable clamping device. Then, the movable clamping device is driven to bring the two spacer bars closer together and into contact. After contact, the whole unit is moved directly below the welding machine 81. The two spacer bars are rotated synchronously to achieve circumferential welding at the joint. After circumferential welding, the two spacer bars become one and their length is increased to meet the requirements. The extended spacer bars can effectively suppress wind vibration and secondary gap oscillation. At the same time, the clamping part between the wire and the spacer bar will reduce the frequency of friction and impact, and avoid aging and loosening of rubber pads and fasteners.

[0033] In this embodiment, a gas collection hood 83 is provided on one side of the welding machine 81. The end of the gas collection hood 83 is connected to an external air extraction device and is used to extract the welding fumes during welding. An industrial camera 82 is provided on the other side of the welding machine 81. The industrial camera 82 is used to capture the annular weld between two spacers. A welding robotic arm 9 is provided inside the gantry frame 2. The welding robotic arm 9 repairs the incomplete parts of the annular weld.

[0034] During operation, the welding machine 81 first receives a start command, triggering the initial signal for the entire process. After receiving the command, it welds and fixes the two spacer bars. During welding, the spacer bars rotate synchronously, so the industrial camera 82 captures the welding area in real time. Then, it identifies defects such as porosity, cracks, and incomplete penetration through algorithms. The industrial camera 82 standardizes and packages the key information such as the location coordinates and type of the identified defects and uses industrial Ethernet, PLC communication modules, etc., to achieve cross-device data interaction between the camera and the robotic arm. Then, it plans the movement path of the robotic arm, accurately locates the defect position, and performs the repair welding operation. After the repair welding is completed, the image acquisition module will detect the repair welding area again to form a closed-loop control, further ensuring the circumferential welding quality of the spacer bars.

[0035] Please refer to this again. Figure 4-6 The movable clamping device includes two support frames 5, and two sets of drive clamping blocks 4, a bidirectional lead screw 51 and two optical shafts 52 are provided between the two support frames 5. The bidirectional lead screw 51 and the two optical shafts 52 are all arranged through the drive clamping blocks 4. The bidirectional lead screw 51 is rotatably connected to the support frame 5, and the two optical shafts 52 are located on both sides of the bidirectional lead screw 51 and fixed between the two support frames 5. The spacer is connected to the sides of the two drive clamping blocks 4.

[0036] In this embodiment, the two reverse threads of the bidirectional lead screw 51 are respectively adapted to the two drive clamps 4. When the bidirectional lead screw 51 rotates, the two drive clamps 4 move closer or further apart through the two reverse threads. When the drive clamps 4 move closer together, the two spacers come into contact with each other and are pressed together. After they are pressed together, the whole thing moves toward the welding machine 81. After moving, the cylinder 7 moves downward to push the lifting platform 8. After the lifting platform 8 moves downward, the welding machine 81 moves downward accordingly. Since the welding machine 81 is located directly above the spacers, the downward movement of the welding machine 81 can contact the joint of the two spacers. As the spacers rotate synchronously, the joint is circumferentially welded to improve the stability of the connection.

[0037] The bottom surface of the support frame 5 mates with the linear guide rail 6, which is fixed to the base 1. A drag chain 53 is installed inside the gantry 2. The push and pull of the drag chain 53 drives the support frame 5 to reciprocate on the linear guide rail 6. Rotating clamping cylinders 41 are located on opposite sides of the two drive clamping blocks 4. The spacer bar is plugged into and pulled into the rotating clamping cylinder 41. The rotating clamping cylinder 41 is conical and has an internal assembly hole 42 for inserting the spacer bar. The inner diameter of the assembly hole 42 is smaller than the outer diameter of the spacer bar, ensuring an interference fit. The assembly hole 42 is cylindrical and has multiple notches 43 arranged in an array around it. When the spacer bar is inserted into the assembly hole 42, the width of the notches 43 increases. A limiting ring 44 is provided around the rotating clamping cylinder 41. Multiple tension springs 45 are provided between the limiting ring 44 and the end face of the rotating clamping cylinder 41. The tension springs 45 pull the limiting ring 44 towards the end face of the rotating clamping cylinder 41.

[0038] Furthermore, one of the drive clamping blocks 4 is provided with a drive motor 46 on its outer side, and the drive motor 46 is connected to the corresponding rotating clamping cylinder 41 in a transmission connection; one of the support frames 5 is provided with a drive motor 511 on its outer side, and the drive motor 511 is connected to the bidirectional lead screw 51 in a transmission connection.

[0039] In use, first install the two spacer bars into the corresponding rotating clamp 41. After installation, drive motor 2 511 runs. After running, the rotation of the bidirectional screw 51 causes the two drive clamps 4 to move closer to each other until the two spacer bars are pressed together. After they are close, the support frame 5 is pulled by the drag chain 53. At this time, the support frame 5 drives the whole to move along the linear guide rail 6 to the bottom of the lifting platform. When the joint of the two spacer bars is directly below the welding machine 81, drive motor 1 46 runs. Since the two spacer bars are in close contact with each other and the drive motor 46 is rotatably connected to one of the rotating clamps 41, the operation of the drive motor 46 causes the other rotating clamp 41 to rotate accordingly, thereby realizing that the two spacer bars rotate together. At this time, the welding machine 81 performs circumferential welding on the rotating joint to meet the length compensation of the extended side.

[0040] In this embodiment, since the rotating clamp 41 is conical and has an assembly hole 42 for inserting a spacer bar, when the spacer bar is inserted into the corresponding assembly hole 42, the rotating clamp 41 will be opened, and the notch 43 will increase after being opened. Since the rotating clamp 41 is conical, when the surrounding tension spring 45 pulls the limiting ring 44, the limiting ring 44 will be subjected to a pulling force that moves towards the end, thereby fastening the conical rotating clamp 41, further preventing the spacer bar from slipping inside the rotating clamp 41, ensuring the stability of the synchronous rotation of the two rotating clamps 41, and improving the quality of the ring welding.

[0041] After the circumferential welding is completed, cylinder 7 retracts, drive motor 46 stops running, and drive motor 511 runs in reverse. At this time, the two drive clamps 4 gradually move away from each other in opposite directions, thereby removing the welded spacer.

[0042] As a preferred option, drive motor one and drive motor two are servo motors.

[0043] Furthermore, the bottom of the gantry frame 2 is provided with a rectangular slot 11, and two steel plates 13 of the same specification are provided in the slot 11. The opposite sides of the two steel plates 13 are in contact with each other, and the outer side of the steel plates 13 is in contact with the T-shaped limiting wheel 12. The inner top wall of the slot 11 is provided with a drive roller 14, and the circumference of the drive roller 14 is in contact with the two steel plates 13. When the drive roller 14 is running, the two steel plates 13 move towards the welding machine 81, wherein the welding machine 81 is located directly above the contact position of the two steel plates 13.

[0044] While meeting the requirements for welding and splicing circular spacer bars, the equipment can also weld two steel plates 13 of the same specification. In real time, the steel plate 13 is first inserted into the slot 11 and the drive roller 14 is started. At this time, when the drive roller 14 is running, the steel plate 13 moves towards the welding machine 81. Similarly, the welding machine moves downward to weld the two steel plates.

[0045] As a preferred option, in order to improve the moving efficiency of the steel plate, a rotating roller can be installed on the surface of the base so that the steel plate rotates on the rotating roller.

[0046] Please refer to this again. Figure 10-12The inner wall of the gantry 2 is also provided with a slag cleaning mechanism 10. The slag cleaning mechanism 10 includes a damping telescopic rod 101 hinged to the inner wall of the gantry 2, a fixed rod 102 fixed to the inner wall of the gantry 2, and a Y-shaped hinge seat 103 hinged to the fixed rod 102. The output end of the damping telescopic rod 101 is hinged to the Y-shaped hinge seat 103. The Y-shaped hinge seat 103 is provided with two symmetrical extrusion rollers 104. The extrusion rollers 104 are made of alloy material. Both extrusion rollers 104 have notches or serrations on their circumference. Since the extrusion rollers 104 can rotate, when the extrusion rollers 104 with notches or serrations continuously contact the circumferential weld position or the weld seam of the steel plate, they can knock off the loose slag, thereby achieving the effect of slag cleaning.

[0047] In this embodiment, when the damping telescopic rod 101 extends, the Y-shaped hinge seat 103 swings downward and contacts the weld of the steel plate 13, as shown. Figure 11 As shown, the welded steel plate moves back and forth on the base 1, causing the extrusion roller 104 to continuously roll on the weld seam, thereby knocking away the weld slag. The height of the connection between the Y-shaped hinge seat 103 and the fixed rod 102 is consistent with the axial height of the spacer bar. When the damping telescopic rod 101 retracts, the circumferential weld position of the spacer bar is located between the two extrusion rollers 104. Figure 12 As shown, when the tow belt 53 pulls the whole body into the gantry 2, the two extrusion rollers 104 will simultaneously contact the circumference of the ring weld. At this time, the drive motor will run again, and the spacer bar after welding will rotate accordingly, thereby cleaning the weld slag after the ring weld.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
