Description

Technical Field

[0001] The invention belongs to the technical field of welding jigs, and particularly relates to a welding device for a gas pipeline bracket and a bracket for overhead laying of a gas pipeline. Background Art

[0002] Gas pipeline brackets are usually made of angle steel. Operators use cutting tools to cut the angle steel into appropriate sizes, then cut a part of triangular material at the inner bent corner of the angle steel, then bend the angle steel, and use a welding jig to clamp the bent angle steel, and then use a welding device for welding. Among them, the welding jig is a key tooling device for fixing, positioning weldments and ensuring welding accuracy, and is widely used in fields such as automobile manufacturing and machining. For example, the welding jig proposed in the patent publication number CN109249174B.

[0003] Currently, most welding jigs can only fix the position of the bent angle steel, and it is difficult to solve the problem of weld misalignment caused by the processing process. In actual production, factors such as the deviation of the bending die accuracy and the uneven bending force often cause the welds of the angle steel not to align after bending. This deviation will break the stress balance of the welded joint, resulting in the stress being highly concentrated at the misaligned position. When the gas pipeline bracket is carrying and operating, these stress concentration points are extremely likely to induce cracks. Over time, the cracks will continue to expand, not only significantly weakening the overall strength and reliability of the structure, but also significantly increasing the risk of damage to the bracket during use, thereby threatening the safe operation of the gas pipeline system.

[0004] Therefore, a welding device for a gas pipeline bracket is proposed to solve the above problems. Summary of the Invention

During the process of welding the gas pipeline support with the welding equipment, the harmful gases generated during welding can be automatically adsorbed and processed, thus avoiding the problem that the operator inhaling the harmful gases will affect the physical health.

[0023] The operating principle of the present invention is described as follows: The operator places the bent angle steel into the two clamping frames 111 (such as Figure 3As shown, then close the door panel 4. Next, the operator sends an electrical signal to the controller inside the control cabinet 3 through the buttons on the surface of the control cabinet 3. The control cabinet 3 will control the two hydraulic cylinders 112 to work. The hydraulic cylinders 112 will drive the clamping plate 12 to move, and use the clamping plate 12 to clamp and fix the vertical part of the angle steel placed in the inner corner of the clamping frame 111. Then the control cabinet 3 controls the first electric push rod 6 to work. The first electric push rod 6 applies pressure to the moving frame 8 and the left clamping frame 111 through the first pressure sensor 7, so that the left clamping frame 111 pushes the bending area on the left side of the angle steel to move to the right, so that the welds are in close contact. And after the control cabinet 3 detects through the first pressure sensor 7 that the extrusion force between the welds reaches 30N, the control cabinet 3 will control the first electric push rod 6 to stop working; Next, the control cabinet 3 controls the induction electric push rod 132 to work. The induction electric push rod 132 will drive the first lead screw linear module 14 and the induction box 17 to move upward together. During the upward movement of the induction box 17, the ball 20 at the upper end of the lifting rod 19 in the induction box 17 will contact the horizontal part of the angle steel and stop moving. And the induction box 17 still moves upward under the drive of the induction electric push rod 132, and the ball 20 will drive a plurality of conduction plates 21 to move relatively downward in the induction box 17 through the lifting rod 19. During the downward movement of one of the conduction plates 21, it will press the trigger switch 43, and the trigger switch 43 will send an electrical signal to the control cabinet 3. After receiving this electrical signal, the control cabinet 3 will control the induction electric push rod 132 to stop working. At this time, the upper surface of the induction box 17 will contact the horizontal part of the angle steel, and the upper end of the ball 20 and the upper surface of the induction box 17 are in the same plane. Then the control cabinet 3 controls the first lead screw linear module 14 to work. The first lead screw linear module 14 will control the bent rod 15 to move to the set position to the left. During the leftward movement of the bent rod 15, it will drive the induction box 17 to move to the left together through the elastic rod and the second pressure sensor 16 (the elastic rod is not labeled in the figure). When the bending area on the left side of the angle steel ( Figure 9 the part marked as a in the figure) is lower than the right side area ( Figure 9When the bent area (marked as a) on the left side of the angle steel is higher than the right side area (marked as b), during the leftward movement of the induction box 17, when passing through the weld seam, the left-side ball 20 and the lifting rod 19 will drive the left-side conduction plate 21 to move upward under the elastic force of the lower spring, so that the two conduction plates 21 are separated. Since after the lifting rod 19 completely retracts into the induction box 17, the two lifting rods 19 on both sides will drive the two conduction plates 21 on both sides to move downward synchronously, and the two conduction plates 21 on both sides will respectively contact the two conductive blocks 23 on both sides. The left conductive block 23 is electrically connected to the external power supply, and the right conductive block 23 is electrically connected to the control cabinet 3. When the left conduction plate 21 moves upward and separates from the right conduction plate 21, the electrical signal transmitted to the control cabinet 3 will be disconnected. When the control cabinet 3 detects this change, it will control the first lead screw linear module 14 to stop working immediately and control the second electric push rod 9 to work. The second electric push rod 9 drives the bent area on the left side of the angle steel to move downward through the clamping assembly 11 on the left side. During the downward movement of the bent area on the left side of the angle steel, it will drive the left-side ball 20, the lifting rod 19 and the conduction plate 21 to move downward together. During the downward movement of the left conduction plate 21, it will contact the right conduction plate 21 again. Referring to the above principle, an electrical signal will be transmitted to the control cabinet 3 again. After the control cabinet 3 detects this change, it means that the weld seam of the angle steel is completely aligned, and it will control the first lead screw linear module 14 and the induction electric push rod 132 to return to the initial state and start the welding work; When the bent area on the left side of the angle steel Figure 9 (the part marked as a) is higher than the right side area Figure 9 (the part marked as b), during the leftward movement of the induction box 17, when passing through the weld seam, the left-side ball 20 and the lifting rod 19 will drive the left-side conduction plate 21 to move upward under the elastic force of the lower spring, so that the two conduction plates 21 are separated. Since after the lifting rod 19 completely retracts into the induction box 17, the two lifting rods 19 on both sides will drive the two conduction plates 21 on both sides to move downward synchronously, and the two conduction plates 21 on both sides will respectively contact the two conductive blocks 23 on both sides. The left conductive block 23 is electrically connected to the external power supply, and the right conductive block 23 is electrically connected to the control cabinet 3. When the left conduction plate 21 moves upward and separates from the right conduction plate 21, the electrical signal transmitted to the control cabinet 3 will be disconnected. When the control cabinet 3 detects this change, it will control the first lead screw linear module 14 to stop working immediately and control the second electric push rod 9 to work. The second electric push rod 9 drives the bent area on the left side of the angle steel to move downward through the clamping assembly 11 on the left side. During the downward movement of the bent area on the left side of the angle steel, it will drive the left-side ball 20, the lifting rod 19 and the conduction plate 21 to move downward together. During the downward movement of the left conduction plate 21, it will contact the right conduction plate 21 again. Referring to the above principle, an electrical signal will be transmitted to the control cabinet 3 again. After the control cabinet 3 detects this change, it means that the weld seam of the angle steel is completely aligned, and it will control the first lead screw linear module 14 and the induction electric push rod 132 to return to the initial state and start the welding work; The control cabinet 3 first controls the air supply pump 341 to work. The air supply pump 341 conveys external gas through the horizontal pipe 342 into the two sealing cylinders 28, increasing the air pressure above the piston rods 29 in the two sealing cylinders 28. Under the action of the air pressure, the two piston rods 29 drive the welding head 30 and the two probe detection mechanisms 33 to move downward together to the set position. And when the welding head 30 and the probe detection mechanisms 33 stop working, the air pressure inside the sealing cylinders 28 and the horizontal pipe 342 will quickly increase to the set threshold value (0.(at a standard atmospheric pressure of 3), after the control cabinet 3 detects this change through the air pressure sensor 36, the control cabinet 3 will control the air supply pump 341 to stop working. Then, the control cabinet 3 controls the adjusting electric push rod 241 to work, so that the adjusting electric push rod 241 drives the second lead screw linear module 242, the adjusting motor 25, the third lead screw linear module 26, the bending plate 27, the welding head 30 and the two probe detection mechanisms 33 to move downward together. During the downward movement of the probe detection mechanism 33, it will contact the angle steel. After the control cabinet 3 detects this change through the third pressure sensor 31 between the left piston rod 29 and the cross plate 32, the control cabinet 3 will control the adjusting electric push rod 241 to stop working and control the second lead screw linear module 242 to work. The second lead screw linear module 242 will drive the adjusting motor 25, the third lead screw linear module 26, the bending plate 27, the welding head 30 and the two probe detection mechanisms 33 to move leftward together. When the left probe detection mechanism 33 moves to the weld, the probe detection mechanism 33 will detect this change, and the left probe detection mechanism 33 will send an electrical signal to the control cabinet 3. The control cabinet 3 will control the second lead screw linear module 242 to stop working and control the adjusting motor 25 to work slowly. The adjusting motor 25 will drive the third lead screw linear module 26, the bending plate 27, the welding head 30 and the two probe detection mechanisms 33 to rotate counterclockwise (from front to back). Since the central axis of the output end of the adjusting motor 25 and the left probe detection mechanism 33 are on the same vertical line, the left probe detection mechanism 33 will rotate in place within the weld, and the right probe detection mechanism 33 and the welding head 30 will rotate with the left probe detection mechanism 33 as the origin. When the right probe detection mechanism 33 rotates into the weld, the right probe detection mechanism 33 will control the adjusting motor 25 to stop working through the control cabinet 3, indicating that the weld is on the moving path of the welding head 30 at this time. Then, the control cabinet 3 controls the pressure relief valve 38 and the left control valve 35 to open, so that the gas in the left sealing cylinder 28 is discharged through the horizontal pipe 342 and the pressure relief pipe 37. Under the action of the spring force, the left piston rod 29 will drive the cross plate 32 and the two probe detection mechanisms 33 to move upward together. Then, the control cabinet 3 controls the third lead screw linear module 26 to work. The third lead screw linear module 26 drives the welding head 30 to move along the weld through the bending plate 27, and welds the weld by using the welding head 30 (a camera is provided on the surface of the bending plate 27, and the camera can take images of the welding head 30 and the weld. The images are analyzed through image processing algorithms to judge whether the welding head 30 is aligned with the weld and whether it is in contact), and the welding of the angle steel can be completed.
