Description

Technical Field

[0001] The present invention relates to the technical field of industrial pipeline processing, and more specifically, to an industrial pipeline processing and welding device. Background Art

[0002] Industrial piping (also known as industrial pipework) is the general term for all tubular facilities within industrial enterprises (such as petroleum, chemical, light industry, pharmaceutical, mining, etc.).

[0003] Inverter DC pulsed argon arc welders are mainly used for welding the splicing between metals to connect and stitch the interfaces between metals. In the processing of industrial pipelines, they have more significant effects, ensuring that no air is generated between industrial pipes during welding, thereby ensuring that the welding is more stable and durable.

[0004] When using existing arc welders, users move the equipment to the industrial pipe to be welded and hold the arc welder to weld the industrial pipeline. The welding process is time-consuming and laborious. In view of this, we propose an industrial pipeline processing and welding device. Summary of the Invention

[0005] The purpose of the present invention is to provide an industrial pipeline processing and welding device to solve the problems raised in the above background art:

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] An industrial pipeline processing and welding device includes an arc welder. An installation plate is provided on one side of the arc welder, a moving mechanism is provided on the installation plate, and a track assembly is provided on one side of the moving mechanism;

[0008] The track assembly includes two semi-circular tracks. Fixing components are provided on the semi-circular tracks, and two groups of the fixing components are respectively provided on both sides of the industrial pipeline.

[0009] Preferably, the moving mechanism includes a gear. The gear is rotatably connected to the installation plate. A motor is provided on the other side of the installation plate. The output shaft of the motor passes through the installation plate and is connected to the gear. Two groups of roller sets are provided on one side of the gear. Each group of roller sets includes two rollers, and the rollers are rotatably connected to the installation plate;

[0010] The two groups of roller sets are respectively provided on the outer side and the inner side of the track assembly. Teeth meshing with the gear are provided on the outer side surface of the semi-circular track. A limiting ring is provided on the side of the semi-circular track close to the installation plate, and the limiting ring is located between the two groups of roller sets.

[0011] Preferably, a limiting slider is provided between the two rollers in each group of roller sets, and the limiting slider moves along the limiting ring.

[0012] Preferably, the end portions of the two semi-circular arc tracks are respectively arranged on the mounting block A and the mounting block B, and the mounting block A and the mounting block B are fixedly connected by bolts.

[0013] Preferably, a limiting protrusion is arranged inside the mounting block A, and a limiting groove matching the limiting protrusion is arranged on the inner side surface of the mounting block B.

[0014] Preferably, the fixing assembly includes a fixing plate. Three fixing plates are arranged on each semi-circular arc track. A cylinder is installed on one side of the middle fixing plate. A sliding groove is formed on the surface of the fixing plate. A limiting slider is slidably connected in the sliding groove. One end of the middle limiting slider is connected to the output shaft of the cylinder;

[0015] A connecting block is arranged on the outer side surface of the limiting slider. A connecting rod A penetrates through the middle connecting block. Connecting rod Bs are slidably connected to the connecting blocks on both sides. Both ends of the connecting rod A are respectively connected to the ends of the two connecting rod Bs.

[0016] Preferably, a limiting pad is arranged inside the limiting slider, and the inner side surface of the limiting pad is an arc-shaped structure.

[0017] Preferably, telescopic rods penetrate through both sides of the limiting slider, and one end of each telescopic rod is connected to the inner wall of the sliding groove.

[0018] Preferably, a welding head fixing cylinder is arranged at the welding head of the arc welder. The welding head fixing cylinder includes an outer fixing cylinder and an inner fixing cylinder. The outer fixing cylinder is slidably connected to the inner fixing cylinder. A limiting screw penetrates through the outer fixing cylinder.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] (1) In the present invention, an arc welding machine is installed on a moving mechanism, and by providing an orbital assembly, the moving mechanism moves along the orbital assembly, thereby driving the arc welding machine to weld and connect two industrial pipelines. Two cylinders are used to simultaneously push the limit slider in the middle to move. When the limit slider in the middle moves, it drives the connecting block and connecting rod A on its surface to move. When connecting rod A moves, it drives connecting rod B to move. The connecting blocks on both sides will receive a force that squeezes inward, causing the limit sliders on both sides to also move inward. At this time, the connecting blocks on both sides slide relative to connecting rod B. By simultaneously adjusting the positions of multiple limit sliders, it is convenient to push the limit pads into close contact with the outer wall of the industrial pipeline. Since the moving distances of multiple limit sliders are the same, the axis of the orbital assembly coincides with the axis line of the industrial pipeline to be welded. Therefore, the distance between the welding head of the arc welding machine and the outer wall of the pipeline is fixed, thus ensuring the stability and accuracy of welding. The length of the welding head fixing cylinder is adjusted to adjust the distance between the welding head of the arc welding machine and the outer wall of the industrial pipeline to a suitable position.

[0021] (2) In the present invention, a motor is used to drive a gear to rotate. Since the outer sides of the two semi-circular arc tracks of the orbital assembly are provided with teeth meshing with the gear, and the orbital assembly is fixed on the outer wall of the industrial pipeline, when the gear rotates, it will rotate around the track of the orbital assembly, thereby driving the mounting plate and the arc welding machine fixed on the mounting plate to move around the guide rail assembly. During the movement of the arc welding machine along with the mounting plate, welding is performed on the industrial pipeline. There is no need to hold the arc welding machine manually for welding, which saves time and effort. A limit ring is provided on the side of the semi-circular arc track close to the mounting plate. The limit ring is located between two sets of roller groups, and a ring groove is provided in the middle of the outer wall of each roller. The edge of the limit ring extends into the ring groove. By respectively arranging the two sets of roller groups on the outer side and the inner side of the orbital assembly, a guiding effect is achieved, enabling the gear to mesh and drive with the teeth on the surface of the semi-circular arc track.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] Embodiment:

[0029] Please refer to Figures 1-4 , an industrial pipeline processing and welding device, including an arc welder 1, a mounting plate 2 is arranged on one side of the arc welder 1, a moving mechanism 3 is arranged on the mounting plate 2, and a track assembly 4 is arranged on one side of the moving mechanism 3, wherein the moving mechanism 3 moves along the track assembly 4;

[0030] The track assembly 4 includes two semi-circular tracks 401, which are movably connected between the two semi-circular tracks 401. A fixing component 5 is arranged on the semi-circular track 401, and the two groups of fixing components 5 are respectively arranged on both sides of the industrial pipeline. The track assembly 4 is fixed on the industrial pipeline to be welded by using the fixing component 5.

[0031] In the present invention, the moving mechanism 3 includes a gear 301, the gear 301 is rotatably connected to the mounting plate 2, a motor 304 is arranged on the other side of the mounting plate 2, and the output shaft of the motor 304 passes through the mounting plate 2 and is connected to the gear 301. The gear 301 is driven to rotate by using the motor 304. Two groups of roller sets 302 are arranged on one side of the gear 301. Each group of roller sets 302 includes two rollers, and the rollers are rotatably connected to the mounting plate 2. The arrangement of the roller sets 302 facilitates driving the mounting plate 2 to move along the guide rail assembly 4;

[0032] Two sets of roller groups 302 are respectively arranged on the outer side and the inner side of the track assembly 4. Teeth meshing with the gear 301 are arranged on the outer side surface of the semi-circular track 401. The motor 304 is used to drive the gear 301 to rotate. Since teeth meshing with the gear 301 are arranged on the outer side surfaces of the two semi-circular tracks 401 of the track assembly 4, and the track assembly 4 is fixed on the outer wall of the industrial pipeline, when the gear 301 rotates, it will rotate around the track of the track assembly 4. A limiting ring 402 is arranged on the side of the semi-circular track 401 close to the mounting plate 2. The limiting ring 402 is located between the two sets of roller groups 302, and a ring groove is formed in the middle of the outer wall of each roller. The edge of the limiting ring 402 extends into the ring groove. By arranging the two sets of roller groups 302 on the outer side and the inner side of the track assembly 4 respectively to play a guiding role, the gear 301 is meshed and driven with the teeth on the surface of the semi-circular track 401, and the rollers in the two sets of roller groups 302 will also rotate by themselves during the movement of the mounting plate 2 around the guide rail assembly 4.

[0033] In the present invention, a limiting slider 303 is arranged between the two rollers in each set of roller groups 302. The limiting slider 303 moves along the limiting ring 402. The position between the limiting ring 402 and the mounting plate 2 is restricted by the arrangement of the limiting slider 303.

[0034] In the present invention, the two ends of the two semi-circular tracks 401 are respectively arranged on the mounting block A 403 and the mounting block B 404. The mounting block A 403 and the mounting block B 404 are fixedly connected by bolts. By arranging the mounting block A 403 and the mounting block B 404, it is convenient to connect the two semi-circular tracks 401 into an integral structure and make it located on the outer wall of the industrial pipeline.

[0035] Among them, a limiting protrusion 405 is arranged on the inner side of the mounting block A 403, and a limiting groove matching with the limiting protrusion 405 is arranged on the inner side surface of the mounting block B 404. When connecting the two semi-circular tracks 401, by pushing the limiting protrusion 405 into the limiting groove, it is convenient to quickly determine the connection position of the two semi-circular tracks 401, and then fix the mounting block A 403 and the mounting block B 404 with bolts to make their quick connection.

[0036] In the present invention, the fixing component 5 includes a fixing plate 501. Three fixing plates 501 are arranged on each semi-circular track 401. The three fixing plates 501 are arranged at equal intervals. A cylinder 502 is installed on one side of the middle fixing plate 501. A sliding groove 503 is formed on the surface of the fixing plate 501. A limiting slider 504 is slidably connected in the sliding groove 503. The limiting slider 504 can move along the sliding groove 503. One end of the middle limiting slider 504 is connected to the output shaft of the cylinder 502;

[0037] On the outer side of the limit slider 504, there is a connecting block 507. A connecting rod A 505 is penetrated through the middle connecting block 507. A connecting rod B 506 is slidably connected to the connecting blocks 507 on both sides. Both ends of the connecting rod A 505 are respectively connected to the ends of the two connecting rods B 506. The cylinder 502 is used to push the middle limit slider 504 to move. When the middle limit slider 504 moves, it drives the connecting block 507 and the connecting rod A 505 on its surface to move. When the connecting rod A 505 moves, it drives the connecting rod B 506 to move. The connecting blocks 507 on both sides will receive a force that squeezes inward, causing the limit sliders 504 on both sides to also move inward. At this time, the connecting blocks 507 on both sides slide relative to the connecting rod B 506. By simultaneously adjusting the positions of multiple limit sliders 504, it is convenient to fix the device on industrial pipes of different thicknesses for welding the industrial pipes, thereby improving the applicable range of the device.

[0038] In the present invention, a welding head fixing cylinder 6 is provided at the welding head of the arc welder 1. The welding head fixing cylinder 6 includes an outer fixing cylinder and an inner fixing cylinder. The outer fixing cylinder is slidably connected to the inner fixing cylinder, which is convenient for adjusting the length of the welding head fixing cylinder 6. A limit screw 7 is penetrated through the outer fixing cylinder, and the limit screw 7 fixes the position between the outer fixing cylinder and the inner fixing cylinder. By providing the welding head fixing cylinder 6 with adjustable length, it is convenient to adjust the distance between the welding head and the industrial pipe according to industrial pipes of different thicknesses, which is convenient for welding.

[0039] In the present invention, a limit pad 509 is provided inside the limit slider 504 to increase the friction between it and the surface of the industrial pipe, making its fixation more stable. The inner side surface of the limit pad 509 is an arc structure, which is convenient for the limit pad 509 to closely fit with the industrial pipe.

[0040] In the present invention, telescopic rods 508 are penetrated through both sides of the limit slider 504. One end of each telescopic rod 508 is connected to the inner wall of the chute 503. The provision of the telescopic rods 508 plays a guiding role in the movement track of the limit slider 504, avoiding the position deviation when the limit slider 504 slides out of the chute 503.

[0041] Working principle: When in use, when it is necessary to weld and connect two industrial pipelines, place the two semi-circular tracks 401 on both sides of the outer wall of one of the industrial pipelines to be welded respectively, make the arc welder 1 located at the interface, and then bring the ends of the two semi-circular tracks 401 closer to each other. By pushing the limit protrusion 405 on the mounting block A403 at the end of one semi-circular track 401 into the limit groove on the mounting block B404 at the end of the other semi-circular track 401, the connection position of the two semi-circular tracks 401 can be determined. Then, connect and fix the mounting block A403 and the mounting block B404 with bolts. Then, use two cylinders 502 to simultaneously push the limit slider 504 in the middle to move. When the limit slider 504 in the middle moves, it drives the connection block 507 and the connecting rod A505 on its surface to move. When the connecting rod A505 moves, it drives the connecting rod B506 to move. The connection blocks 507 on both sides will receive a force that squeezes inward, causing the limit sliders 504 on both sides to also move inward. At this time, the connection blocks 507 on both sides slide relative to the connecting rod B506. By simultaneously adjusting the positions of multiple limit sliders 504, it is convenient to push the limit pad 509 into close contact with the outer wall of the industrial pipeline. Since the moving distances of multiple limit sliders 504 are the same, the axis of the track assembly 4 coincides with the axis line of the industrial pipeline to be welded. Then, adjust the length of the welding head fixing cylinder 6 to adjust the distance between the welding head of the arc welder 1 and the outer wall of the industrial pipeline to an appropriate position. Finally, start welding. While turning on the arc welder 1, use the motor 304 to drive the gear 301 to rotate. Since the outer sides of the two semi-circular tracks 401 of the track assembly 4 are provided with teeth meshing with the gear 301, and the track assembly 4 is fixed on the outer wall of the industrial pipeline, when the gear 301 rotates, it will rotate around the track of the track assembly 4, thereby driving the mounting plate 2 and the arc welder 1 fixed on the mounting plate 2 to move around the guide rail assembly 4. During the movement of the arc welder 1 along with the mounting plate 2, the industrial pipeline is welded. There is no need to hold the arc welder 1 manually for welding, which saves time and effort. A limit ring 402 is provided on one side of the semi-circular track 401 close to the mounting plate 2. The limit ring 402 is located between the two sets of roller groups 302, and a ring groove is provided in the middle of the outer wall of each roller. The edge of the limit ring 402 extends into the ring groove. By arranging the two sets of roller groups 302 on the outer side and the inner side of the track assembly 4 respectively to play a guiding role, the gear 301 is engaged and driven with the teeth on the surface of the semi-circular track 401, and the rollers in the two sets of roller groups 302 will also rotate by themselves during the movement of the mounting plate 2 around the guide rail assembly 4.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
