Description

Technical Field

[0001] This invention relates to the field of intelligent welding technology, and in particular to an intelligent welding device and method based on the processing of ventilation fumigation pressure relief pipes for grain silos. Background Technology

[0002] The intelligent welding device for processing pressure-reducing pipes for grain silos is a specialized piece of equipment combining automated welding technology with grain storage equipment manufacturing. It uses a computer-controlled welding robot, integrating laser sensors and visual positioning technologies, to achieve high-precision welding of pressure-reducing pipes (such as central guide pipes and auxiliary ventilation / fumigation pipes) in silos, ensuring weld quality and airtightness requirements. Its core functions include: 1. Intelligent parameter adjustment: Automatically optimizing welding current, voltage, and path planning based on the material (e.g., steel) and structural characteristics (e.g., semi-circular cross-section or mesh-like ventilation holes) of the pressure-reducing pipe to adapt to the welding needs of different pipe components. 2. Multi-directional welding capability: Automated welding of straight and circumferential welds is achieved through a rotary motor and adjustable clamping mechanism, meeting the processing requirements of three-dimensional structures of the pressure-reducing pipe. 3. Quality monitoring: Real-time detection of deformation or defects during the welding process using sensors ensures the strength of the pressure-reducing pipe and the reliability of the ventilation / fumigation function.

[0003] For example, the prior art patent publication number CN213257982U discloses a welding device for a silo. This device includes a base, with a receiving groove on the top outer wall of the base. A partition is welded to the inner wall of the receiving groove. A lead screw is rotatably connected to one side of the outer wall of the partition, and a servo motor is bolted to the other side of the outer wall of the partition. The output end of the servo motor is connected to the input end of the lead screw via a coupling. Two limiting posts are welded to one side of the outer wall of the partition and one side of the inner wall of the receiving groove. A movable seat is rotatably connected to the outer circumference of the lead screw. A rack column is welded to the top outer wall of the movable seat. A sliding frame is slidably connected to the outer walls of the rack column. The same driving gear is rotatably connected to the inner wall of the sliding frame on opposite sides. The outer circumference of the driving gear meshes with the outer wall of the rack column on one side. The device features a rotating roller with a cylindrical structure at one end and a conical structure at the other, facilitating the placement of cylindrical and conical silo assemblies. When placing two cylindrical silo assemblies, the placement plate and guide plate are parallel. A second bidirectional motor drives the rotating roller to rotate, allowing the silo assemblies to rotate and facilitating welding at the connection between adjacent silos. When welding is required between conical and cylindrical silo assemblies, a hydraulic cylinder rotates the placement plate to a certain angle, causing the conical surface of the rotating roller to fit against the outer wall of the conical silo assembly. The second bidirectional motor then rotates the conical silo assembly, facilitating welding.

[0004] Existing welding equipment cannot efficiently weld the special shape of the ventilation, fumigation and pressure-reducing pipes of grain silos. It can only be adjusted individually, and different parameters are used to align and weld different parts of the silo, which is not targeted. Summary of the Invention

[0047] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0048] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the intelligent welding device based on the processing of ventilation, fumigation and pressure reduction pipes for grain silos includes a welding frame, on which the silo body 1 is placed. The welding frame includes at least two first fixed rings 2, and the inner ring of each first fixed ring 2 has a first rotating ring 3. The silo body 1 is placed on the inner wall of the first rotating ring 3, and the first rotating ring 3 rotates relative to the first fixed ring 2. The first rotating ring 3 can drive the silo body 1 to rotate. The device also includes a welding device 4, which is used to weld the various nodes 5 of the silo body 1 to the silo body 1.

[0049] like Figure 5 As shown, a conveyor frame 6 is provided between two adjacent first fixed rings 2, and a conveyor track 46 is provided below the conveyor frame 6. The conveyor frame 6 and the conveyor track 46 are slidably connected. The conveyor frame 6 is used to convey the node 5 to the bottom of the silo body 1 to be welded.

[0050] A lifting plate 7 is provided at one end of the conveyor frame 6 near the silo body 1. A first telescopic rod 8 is connected to the bottom of the lifting plate 7. The first telescopic rod 8 drives the lifting plate 7 to rise so that the node 5 is raised to the welding position of the silo body 1. Then, the node 5 is welded to the silo body 1 by the welding device 4. The silo body 1 is rotated by the first rotating ring 3 so as to align the other welding positions of the node 5 with the welding device 4.

[0051] Continue reading Figure 5 One end of the conveying track 46 is connected to the second rack 43, and one end of the conveying frame 6 is fixed to the fifth motor 45. The output end of the fifth motor 45 is connected to the third gear 44, which meshes with the second rack 43.

[0052] Through the above scheme, the fifth motor 45 drives the third gear 44 to rotate. Since the third gear 44 meshes with the second rack 43, it can drive the entire conveyor frame 6 to slide along the conveyor track 46. When it moves to the right end of the conveyor track 46 (with... Figure 5 When the direction is referenced, the node 5 to be welded can be placed on the conveyor frame 6. When it moves to the bottom of the conveyor track 46 (that is, directly below the silo 1), the lifting plate 7 is raised by the first telescopic rod 8, which in turn moves the node 5 up to contact the welding position of the silo 1. Then, the node 5 and the silo 1 are welded by the welding device 4.

[0053] like Figure 1 , Figure 6 As shown, one end of the welding frame is provided with a first conveyor 9 and a rotating frame 10. The first conveyor 9 is used to transport several cone cages 11 to the end of the silo body 1 to be welded. The rotating frame 10 is movably connected to the base 12 of the welding frame. The rotating frame 10 picks up the cone cages 11, then rotates the cone cages 11 to the position corresponding to the end of the silo body 1. Finally, the cone cages 11 and the silo body 1 are welded by the welding device 4.

[0054] Continue reading Figure 6 As a specific movement mode of the rotating frame 10, a fixed plate 13 is fixedly connected to the bottom of the first conveyor 9, and a sliding frame 14 is provided below the fixed plate 13. The top two ends of the sliding frame 14 are hinged to the two ends of the rotating frame 10, and the bottom of the sliding frame 14 is slidably connected to the top of the base 12. One end of the sliding frame 14 is also connected to a second telescopic rod 15, and the second telescopic rod 15 is fixedly connected to the bottom of the first conveyor 9.

[0055] It should be noted that in the above scheme, the rotating frame 10 is in the shape of a semi-conical sleeve, which matches the shape of the conical cage 11, such as... Figure 6 As shown in the first state on the left, when the second telescopic rod 15 moves the rotating frame 10 towards the first conveyor 9 and reaches its limit position, under the squeezing action of the fixed plate 13, the rotating frame 10 tilts slightly to the right. In this state, when the cone cage 11 is conveyed to the right by the first conveyor 9, it automatically falls into the rotating frame 10 and is accommodated by the special shape of the rotating frame 10. When the second telescopic rod 15 continues to drive the rotating frame 10 to move to the right, as the support point of the fixed plate 13 and the rotating frame 10 gradually moves to the left side of the rotating frame 10, the rotating frame 10 gradually rotates clockwise under the action of gravity until it reaches the left side. Figure 6In the third state on the right, the rotating frame 10 and the cone cage 11 are in a horizontal state. In this state, the cone cage 11 and the silo body 1 are concentric. When the second telescopic rod 15 continues to drive the rotating frame 10 and the cone cage 11 to move in the opposite direction to the silo body 1, the cone cage 11 can be connected to the silo body 1, which is convenient for the next welding work.

[0056] It should also be noted that, in order to prevent the rotating frame 10 from rotating excessively, a baffle 16 is provided in the middle of the sliding frame 14. The baffle 16 ensures that the bottom of the rotating frame 10 can only rotate to a state perpendicular to the horizontal plane.

[0057] like Figure 7 , Figure 8 As shown, the welding device 4 is connected to the base of the welding frame via a conversion arm 17, and the welding device 4 and the conversion arm 17 are connected via a first magnetic attraction structure. The conversion arm 17 is used to drive the welding device 4 to move on the base 12 to realize the welding work at various positions of the chamber 1.

[0058] like Figure 9 As shown, a slide bar 18 is provided below the conversion arm 17. The two ends of the slide bar 18 are fixedly connected to the top of the base 12. The bottom of the conversion arm 17 is slidably connected to the outer wall of the slide bar 18. A first motor 19 is provided at one end of the slide bar 18. The output end of the first motor 19 is connected to a third telescopic rod 20. The telescopic end of the third telescopic rod 20 is fixedly connected to the outer wall of the conversion arm 17.

[0059] In the above scheme, the first motor 19 can drive the conversion arm 17 to rotate around the slide rod 18, and the third telescopic rod 20 can drive the conversion arm 17 to slide along the slide rod 18, thereby achieving the function of adjusting the position of the welding device 4. Figure 9 The first state shown on the left is used for welding node 5 of the compartment 1, as follows: Figure 9 The third state shown on the right is used for welding the cone cage 11 of the silo body 1.

[0060] like Figure 10As shown, a sliding box 21 is fixedly connected to the top of the conversion arm 17. A fixed seat 22 is provided on one side of the sliding box 21. The welding device 4 is slidably mounted on one end of the fixed seat 22. A fourth telescopic rod 23 is connected to the end of the welding device 4 away from the welding head. The other end of the fourth telescopic rod 23 is fixedly connected to the fixed seat 22. The fourth telescopic rod 23 can drive the welding device 4 to move relative to the fixed seat 22. A sliding block 24 is provided inside the sliding box 21. A first electromagnet (not shown in the figure) is provided inside the sliding block 24. A permanent magnet 25 is connected to the end of the fixed seat 22 near the sliding block 24. The permanent magnet 25 can attract the first electromagnet, thereby allowing the fixed seat 22 and the sliding block 24 to move relative to each other. Block 24 remains fixed. One end of the sliding block 24 is connected to a limiting plate 26. The limiting plate 26 slides in a limited manner with a limiting protrusion at one end of the sliding box 21. A second motor 28 is fixedly installed on the limiting plate 26. The output end of the second motor 28 is connected to a first gear 27. One end of the sliding box 21 is connected to a first rack 29. The first gear 27 meshes with the first rack 29. Since the second motor 28 is fixed on the limiting plate 26, when the second motor 28 drives the first gear 27 to rotate, it can drive the limiting plate 26 and the sliding block 24 to slide along the sliding box 21, thereby adjusting the position of the fixed seat 22 and the welding device 4, and thus welding the node 5 and the chamber 1.

[0061] like Figure 11 As shown, a second fixed ring 30 is provided between the rotating frame 10 and the first fixed ring 2. A second rotating ring 31 is provided inside the second fixed ring 30. The second rotating ring 31 is rotatably connected to the inside of the second fixed ring 30. The second rotating ring 31 can be connected to the welding device 4 through a second magnetic attraction structure. A toothed ring 32 is connected around the second rotating ring 31. A third motor 33 is fixedly installed at the bottom of the second fixed ring 30. A second gear 34 is connected to the output end of the third motor 33. The second gear 34 meshes with the toothed ring 32. The third motor 33 drives the second gear 34 to rotate, which in turn drives the toothed ring 32 and the second rotating ring 31 to rotate. A second electromagnet 35 is connected to the side of the second rotating ring 31. A magnetic attraction groove (not shown in the figure) corresponding to the second electromagnet 35 is opened on the side of the fixed seat 22. A permanent magnet is also provided inside the magnetic attraction groove. When the fixed seat 22 is moved to the position by the conversion arm 17, Figure 9 In the third state on the right, the third motor 33 drives the second rotating ring 31 to rotate so that the second electromagnet 35 is concentric with the magnetic attraction groove on the side of the fixed seat 22. Then, the fixed seat 22 is moved by the third telescopic rod 20 so that the second electromagnet 35 is attracted to the magnetic attraction groove, and at the same time the first electromagnet is closed, thereby separating the fixed seat 22 from the sliding block 24 inside it. The welding device 4 is driven by the second rotating ring 31 to rotate around the cone cage 11 so as to weld the entire circle of the cone cage 11 to the chamber body 1.

[0062] like Figure 12 As shown, the inner wall of the first rotating ring 3 is provided with at least three extrusion members 36. All three extrusion members 36 are connected to the inner wall of the first rotating ring 3 through the fifth telescopic rod 37. The three extrusion members 36 approach each other to clamp the chamber 1. With the rotational driving force of the first rotating ring 3, the chamber 1 is rotated 360°, thereby welding the nodes 5 at different positions around the chamber 1.

[0063] Continue reading Figure 12 As the driving method for the first rotating ring 3, a worm gear 38 is connected to the outer wall of the driving ring 3, a fourth motor 39 is connected to the bottom end of the first fixed ring 2, and a worm 40 is connected to the output end of the fourth motor 39. The worm 40 meshes with the worm gear 38.

[0064] like Figure 1 , Figure 12 , Figure 13 As shown, the bottom of the first fixing ring 2 is slidably connected to the slide rail at the top of the base 12, and a sixth telescopic rod 41 is also connected to one side of the first fixing ring 2. The other end of the sixth telescopic rod 41 is fixed to the top of the base 12. The first fixing ring 2 can be slid through the sixth telescopic rod 41, thereby adjusting the position of each first fixing ring 2, so as to effectively clamp the bins 1 of different lengths. A second conveyor 42 is provided at one end of the welding frame. The second conveyor 42 is used to transport the bins 1 into the first fixing ring 2.

[0065] Example 2: Includes the following steps:

[0066] S1. Placement and Fixing of Silo Body: The second conveyor 42 transports the silo body 1 to the welding frame position. The silo body 1 slides into multiple first fixing rings 2 via the base 12 slide rail. The sixth telescopic rod 41 at the bottom of the first fixing ring 2 can push the first fixing ring 2 to move along the slide rail and adjust the spacing to clamp silo bodies 1 of different lengths. Subsequently, the three extrusion parts 36 in the first rotating ring 3 are driven by the fifth telescopic rod 37 to move closer to each other and clamp the outer wall of the silo body 1. The fourth motor 39 drives the first rotating ring 3 to rotate through the worm gear 40 and worm wheel 38, providing a rotational basis for subsequent welding.

[0067] S2, Node Welding Process: Node 5 moves via the conveyor frame 6 on the conveyor track 46; the fifth motor 45 drives the third gear 44 to mesh with the second rack 43, pushing the conveyor frame 6 along the conveyor track 46 to directly below the chamber 1; the first telescopic rod 8 is activated, driving the lifting plate 7 to lift node 5 to the welding position on the chamber 1; the chamber 1 rotates via the first rotating ring 3, moving different alignment points of node 5 to the welding device 4; the welding device 4 is controlled by the conversion arm 17, the first motor 19 drives it to rotate on the slide rod 18, and the third telescopic rod 20 pushes it to move back and forth; the fourth telescopic rod 23 in the fixed seat 22 finely adjusts the position of the welding device 4 to ensure that the welding head contacts node 5 and welds the chamber 1 firmly.

[0068] S3, Cone Cage Welding Stage: The cone cage 11 is conveyed to the rotating frame 10 by the first conveyor 9; the second telescopic rod 15 pushes the sliding frame 14 to move towards the first conveyor 9, and the rotating frame 10 receives the cone cage 11 in an inclined state under the pressure of the fixed plate 13; the second telescopic rod 15 continues to push to the right, and the rotating frame 10 rotates to a horizontal position under gravity (limited by the baffle 16), aligning the cone cage 11 concentrically with the silo body 1; the conversion arm 17 moves the welding device 4 to the third state, closes the first electromagnet in the sliding block 24 to separate the fixed seat 22, and magnetically attracts the fixed seat 22 through the second electromagnet 35 of the second rotating ring 31; the third motor 33 drives the second gear 34 to drive the gear ring 32, so that the welding device 4 rotates around the cone cage 11 for one revolution, completing the welding of the joint between the cone cage 11 and the silo body 1.

[0069] In summary, this invention, through the design of the first rotating ring and the fixed ring, can automatically drive the silo body 1 to rotate, and combined with the intelligent adjustment of the welding device 4, achieves all-round welding of node 5 of the silo body 1. This reduces manual intervention and improves production efficiency. Especially in the processing of large silos, it avoids the trouble of repeated positioning, making the overall welding process continuous and intelligent, and enhancing processing reliability. Through the conveyor frame, lifting plate 7 and telescopic rod mechanism, node 5 can be accurately conveyed to the bottom of the silo body 1 and lifted to the position to be welded, achieving alignment at different angles in conjunction with the rotation of the silo body 1. The welding device 4 has a conversion arm and a magnetic structure, which can flexibly adjust the position and posture to ensure that the welding head is always aligned with the workpiece, reducing errors, improving welding quality, and adapting to the welding requirements of complex geometric structures. The arm drives the welding device 4 to move, integrating the welding functions of node 5 and cone cage 11. Through the coordinated work of the rotating frame 10 and the conversion arm, the cone cage 11 is automatically picked up and rotated to a horizontal state, connecting concentrically with the silo body 1. The welding device 4 switches between different working modes through the first magnetic attraction structure and the second magnetic attraction structure to meet the unified processing of various workpiece types, optimize space utilization, reduce equipment redundancy, and shorten the overall processing cycle. By setting the welding frame base with slide rails and a sixth telescopic rod, the spacing of multiple first fixed rings can be slidably adjusted to accommodate silo bodies 1 of different lengths.
