Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to an automatic assembly and welding device for steel pipe tower components and its welding method. Background Technology

[0002] With the widespread application of steel structures in construction, bridges, and other fields, the reliability and safety requirements for steel pipe towers are becoming increasingly stringent. A steel pipe tower is composed of multiple steel pipes that need to be connected, and these connection points require welding. Traditionally, this welding work is usually done manually, but this method has many problems, such as difficulty in guaranteeing weld quality, low production efficiency, and high difficulty for operators.

[0003] An existing welding device for splice seams of power steel pipe towers (publication number: CN218426392U) has at least the following drawbacks: The aforementioned patent uses a servo motor of a lifting mechanism to drive a gear to rotate, causing the gear to mesh with the lifting frame and adjust the lifting frame's position up and down, positioning the welding head at the required welding position on the power steel pipe tower. Then, the moving support mechanism moves, driving the entire lifting mechanism to move and weld the seam. However, when using the welding head to weld the butt joint of the tower, the weld width of the welding head is limited, which can easily lead to low weld strength at the tower butt joint, affecting the welding quality of the tower. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic assembly and welding device and welding method for steel pipe tower components.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic assembly and welding device for steel pipe tower components includes:

[0007] V-shaped base, the V-shaped base being used to place the tower to be welded;

[0008] Two limiting mechanisms are symmetrically installed on the top of the V-shaped base for clamping and limiting the tower to be welded;

[0009] A pushing mechanism is installed at one end of a V-shaped base and is used to push the tower cylinder to move within the V-shaped base;

[0010] A welding mechanism, which is mounted on a V-shaped base and positioned between two limiting mechanisms, is used to perform circumferential welding on the butt joint between the two tower sections.

[0011] The welded structure includes:

[0012] The welding head is used for welding the tower section joint;

[0013] The oscillating component, which is in transmission cooperation with the welding mechanism, is used to drive the welding head to oscillate left and right during welding.

[0014] As a further embodiment of the present invention, the limiting mechanism includes a portal plate fixedly installed on the top of the V-shaped base, a first electric telescopic rod fixedly installed on the top of the portal plate, and a V-shaped clamping block fixedly installed on the telescopic end of the first electric telescopic rod.

[0015] As a further embodiment of the present invention, the pushing assembly includes second electric telescopic rods that are symmetrically fixedly installed on the outer surfaces of opposite sides of the V-shaped base, and a pushing plate is fixedly installed between the telescopic ends of the two second electric telescopic rods.

[0016] As a further embodiment of the present invention, the welding mechanism further includes a support ring fixedly installed on the upper surface of the V-shaped base. A rotating ring is rotatably installed on the inner wall of the support ring, and a U-shaped plate is fixedly installed on the inner wall of the rotating ring. A third electric telescopic rod is fixedly installed on the inner side of the U-shaped plate. The welding head is rotatably installed with the telescopic end of the third electric telescopic rod. An industrial camera for detecting whether the two towers are aligned is fixedly installed on the outer surface of the U-shaped plate.

[0017] As a further embodiment of the present invention, the swing assembly includes a rectangular frame that is laterally slidably installed between the inner walls of opposite sides of the U-shaped plate. Limiting telescopic rods are fixedly installed on the outer surfaces of both ends of the rectangular frame. A limiting frame is fixedly installed at the telescopic end of the limiting telescopic rod. A synchronous connection assembly is installed between the limiting frame and the telescopic end of the third electric telescopic rod. A guide frame is vertically fixedly installed on the outer surface of the limiting frame. A guide post is fixedly installed on the outer surface of the welding head. The guide post is slidably installed against the inner wall of the guide frame. A plurality of protruding beads are fixedly installed equidistantly in the circumferential direction on the outer surfaces of opposite sides of the support ring. The protruding beads are staggered. A corresponding lever block is fixedly installed at the top of the limiting telescopic rod.

[0018] As a further embodiment of the present invention, the synchronous connection assembly includes two limiting rings fixedly installed on the telescopic end of the third electric telescopic rod, and the limiting frame is installed between the two limiting rings.

[0019] As a further embodiment of the present invention, a striking mechanism for removing weld slag from the weld surface is installed on the inner side of the rotating ring near the U-shaped plate. The striking mechanism includes a spring rod fixedly installed on the inner side of the rotating ring. A U-shaped frame is fixedly installed on the telescopic end of the spring rod. A striking hammer is fixedly installed on the bottom end of the U-shaped frame. Top blocks are fixedly installed on the top of the U-shaped frame on both sides of the inner wall. The bottom end of the top block intermittently abuts against the outer side of a number of protruding beads.

[0020] As a further embodiment of the present invention, a stepper motor is fixedly installed on the outer surface of the support ring, a drive gear is fixedly installed at the output end of the stepper motor, a rectangular opening is provided through the outer periphery of the support ring for the drive gear to pass through, and a plurality of tooth grooves that mesh with the drive gear are uniformly provided in the circumferential direction of the outer periphery of the rotating ring.

[0021] An automated assembly and welding method for steel pipe tower components includes the following steps:

[0022] S1: Place the two towers to be welded onto the V-shaped base, and move the pusher plate by pulling the telescopic end of the second electric telescopic rod, so that the pusher plate pushes the two towers toward the middle position of the V-shaped base, and monitor the joint between the two towers by an industrial camera installed on the rotating ring, so that the joint between the two towers is aligned with the welding head.

[0023] S2: After the positions of the two towers are determined, the V-shaped clamp is pushed downward by the telescopic end of the first electric telescopic rod, so that the V-shaped clamp and the V-shaped base work together to clamp and limit the two towers.

[0024] S3: After the two towers are fixed, the welding head is moved down as a whole by the telescopic end of the third electric telescopic rod, so that the welding end of the welding head moves to the joint and the welding head performs welding operation on the joint of the two towers.

[0025] S4: During welding, a stepper motor drives the drive gear to rotate. Since the drive gear meshes with the toothed groove on the outer circumference of the rotating ring, the drive gear can drive the rotating ring to rotate slowly through the toothed groove, so that the welding head installed on the rotating ring can rotate around the tower to achieve a complete welding operation of the butt joint.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. The drive gear is driven to rotate by a stepper motor. Since the drive gear meshes with the toothed groove on the outer circumference of the rotating ring, the drive gear can drive the rotating ring to rotate slowly through the toothed groove, so as to drive the welding head installed on the rotating ring to rotate around the tower to achieve the full welding operation of the butt joint.

[0028] 2. As the rotating ring drives the welding head to rotate, the paddles installed at the top of the symmetrically arranged limiting telescopic rods will contact the protrusions installed on both sides of the support ring. Under the pressure of the relatively staggered protrusions, the limiting telescopic rods and the limiting frame will move back and forth laterally, so that the guide frame installed on the limiting frame can drive the welding head to swing back and forth through the guide column. This allows the welding head to perform swing welding on the tower joint, increasing the welding width at the joint, thereby increasing the welding strength at the tower joint and improving the welding quality of the tower.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] See attached document Figure 1 -Appendix Figure 7 An automatic assembly and welding device for steel pipe tower components, comprising:

[0040] V-shaped base 1, V-shaped base 1 is used to place the tower to be welded;

[0041] Two limiting mechanisms are symmetrically installed on the top of the V-shaped base 1 to clamp and limit the tower to be welded;

[0042] The material pushing mechanism is installed at one end of the V-shaped base 1 and is used to push the tower to move within the V-shaped base 1. The material pushing assembly includes second electric telescopic rods 5 that are symmetrically fixedly installed on the outer surfaces of opposite sides of the V-shaped base 1. A material pushing plate 6 is fixedly installed between the telescopic ends of the two second electric telescopic rods 5.

[0043] The welding mechanism is mounted on the V-shaped base 1 and positioned between the two limiting mechanisms. It is used to perform circumferential welding on the butt joint between the two tower sections.

[0044] The welded structure includes:

[0045] Welding head 11 is used to weld the tower section joint;

[0046] The oscillating component, which is connected to the welding mechanism, is used to drive the welding head 11 to oscillate left and right during welding.

[0047] In use, two towers to be welded are placed on the V-shaped base 1. The pusher plate 6 is moved by the telescopic end of the second electric telescopic rod 5, so that the pusher plate 6 pushes the two towers towards the middle position of the V-shaped base 1. The industrial camera 20 installed on the rotating ring 8 monitors the joint between the two towers, so that the joint between the two towers is aligned with the welding head 11, so that the joint can be welded by the welding head 11 in the future.

[0048] In this embodiment, the limiting mechanism includes a gate-shaped plate 2 fixedly installed on the top of the V-shaped base 1, a first electric telescopic rod 3 fixedly installed on the top of the gate-shaped plate 2, and a V-shaped clamping block 4 fixedly installed on the telescopic end of the first electric telescopic rod 3.

[0049] After the positions of the two towers are determined, the V-shaped clamp 4 is pushed downward by the telescopic end of the first electric telescopic rod 3, so that the V-shaped clamp 4 and the V-shaped base 1 work together to clamp and limit the two towers, so as to prevent the towers from moving during welding and affecting the welding accuracy.

[0050] In this embodiment, the welding mechanism also includes a support ring 7 fixedly installed on the upper surface of the V-shaped base 1. A rotating ring 8 is rotatably installed on the inner wall of the support ring 7. A U-shaped plate 9 is fixedly installed on the inner wall of the rotating ring 8. A third electric telescopic rod 10 is fixedly installed on the inner side of the U-shaped plate 9. The welding head 11 is rotatably installed on the telescopic end of the third electric telescopic rod 10. An industrial camera 20 for detecting whether the two towers are aligned is fixedly installed on the outer surface of the U-shaped plate 9.

[0051] After the two tower sections are fixed, the welding head 11 is moved down as a whole by the telescopic end of the third electric telescopic rod 10, so that the welding end of the welding head 11 is moved to the joint, so that the welding head 11 can be used to weld the joint of the two tower sections.

[0052] In this embodiment, the swing assembly includes a rectangular frame 16 that is laterally slidably installed between the inner walls of opposite sides of the U-shaped plate 9. Limiting telescopic rods 17 are fixedly installed on the outer surfaces of both ends of the rectangular frame 16. Limiting frame 15 is fixedly installed at the telescopic end of the limiting telescopic rod 17. A synchronous connection assembly is installed between the telescopic end of the limiting frame 15 and the telescopic end of the third electric telescopic rod 10. A guide frame 13 is vertically fixedly installed on the outer surface of the limiting frame 15. A guide post 14 is fixedly installed on the outer surface of the welding head 11. The guide post 14 is slidably installed on the inner wall of the guide frame 13. A plurality of protruding beads 19 are fixedly installed equidistantly in the circumferential direction on the outer surfaces of opposite sides of the support ring 7. The protruding beads 19 are staggered. A lever 18 corresponding to the protruding beads 19 is fixedly installed at the top of the limiting telescopic rod 17.

[0053] While the rotating ring 8 drives the welding head 11 to rotate, the paddle 18 installed at the top of the symmetrically arranged limiting telescopic rod 17 will contact the protruding balls 19 installed on both sides of the support ring 7 respectively. Under the pressure of the relatively staggered protruding balls 19, the limiting telescopic rod 17 and the limiting frame 15 will move back and forth laterally, so that the guide frame 13 installed on the limiting frame 15 can drive the welding head 11 to swing back and forth through the guide column 14, so that the welding head 11 can swing and weld the tower joint, increase the welding width at the joint, thereby increasing the welding firmness at the tower joint and improving the welding quality of the tower.

[0054] In this embodiment, the synchronous connection component includes two limiting rings 12 fixedly installed on the telescopic end of the third electric telescopic rod 10, and a limiting frame 15 installed between the two limiting rings 12. In use, when the telescopic end of the third electric telescopic rod 10 moves axially, it will drive the limiting frame 15 to move up and down as a whole through the two limiting rings 12, so as to ensure the consistency of the position of the guide frame 13 installed on the limiting frame 15 and the guide post 14 installed on the welding head 11.

[0055] In this embodiment, a striking mechanism for removing weld slag from the weld surface is installed on the inner side of the rotating ring 8 near the U-shaped plate 9. The striking mechanism includes a spring rod 25 fixedly installed on the inner side of the rotating ring 8. A U-shaped frame 26 is fixedly installed on the telescopic end of the spring rod 25. A striking hammer 28 is fixedly installed on the bottom end of the U-shaped frame 26. Top blocks 27 are fixedly installed on the top of the U-shaped frame 26 relative to the inner walls on both sides. The bottom end of the top blocks 27 intermittently abuts against the outer side of several protruding beads 19.

[0056] While the rotating ring 8 rotates, the U-shaped frame 26 moves via the spring rod 25. As the U-shaped frame 26 moves, the top block 27 installed at its top will pass through multiple protruding balls 19 installed on the outside of the support ring 7 in sequence. The protruding balls 19, together with the top block 27 and the spring rod 25, make the U-shaped frame 26 move up and down continuously, so that the hammer 28 installed at the bottom of the U-shaped frame 26 can knock off the slag on the surface of the weld after welding.

[0057] In this embodiment, a stepper motor 22 is fixedly installed on the outer surface of the support ring 7, and a drive gear 23 is fixedly installed at the output end of the stepper motor 22. A rectangular opening 21 is opened through the outer periphery of the support ring 7 for the drive gear 23 to pass through. Multiple tooth grooves 24 that mesh with the drive gear 23 are evenly opened in the circumferential direction of the outer periphery of the rotating ring 8.

[0058] During welding, the stepper motor 22 drives the drive gear 23 to rotate. Since the drive gear 23 meshes with the toothed groove 24 on the outer circumference of the rotating ring 8, the drive gear 23 can drive the rotating ring 8 to rotate slowly through the toothed groove 24, so as to drive the welding head 11 installed on the rotating ring 8 to rotate around the tower to achieve a complete welding operation of the butt joint.

[0059] An automated assembly and welding method for steel pipe tower components includes the following steps:

[0060] S1: Place the two towers to be welded on the V-shaped base 1, and pull the pusher plate 6 to move by the telescopic end of the second electric telescopic rod 5, so that the pusher plate 6 pushes the two towers to the middle position of the V-shaped base 1, and monitors the joint of the two towers by the industrial camera 20 installed on the rotating ring 8, so that the joint of the two towers is aligned with the welding head 11.

[0061] S2: After the positions of the two towers are determined, the V-shaped clamping block 4 is pushed downward by the telescopic end of the first electric telescopic rod 3, so that the V-shaped clamping block 4 and the V-shaped base 1 are used to clamp and limit the two towers.

[0062] S3: After the two towers are fixed, the welding head 11 is moved down as a whole by the telescopic end of the third electric telescopic rod 10, so that the welding end of the welding head 11 moves to the joint and the welding head 11 performs welding operation on the joint of the two towers.

[0063] S4: During welding, the stepper motor 22 drives the drive gear 23 to rotate. Since the drive gear 23 meshes with the toothed groove 24 on the outer circumference of the rotating ring 8, the drive gear 23 can drive the rotating ring 8 to rotate slowly through the toothed groove 24, so as to drive the welding head 11 installed on the rotating ring 8 to rotate around the tower to achieve a complete welding operation of the butt joint.

[0064] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
