Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to an automatic testing equipment for stainless steel pipe welds. Background Technology

[0002] The stainless steel pipe weld inspection device mainly focuses on the accurate, efficient and reliable inspection of weld quality. As a key part of the stainless steel pipe connection, the quality of the weld directly affects the safety and stability of the entire pipeline system.

[0003] Currently, the inspection of welds on some stainless steel pipes mainly relies on manual inspection. Manual inspection requires turning the stainless steel pipes over, which not only increases the labor intensity of operators but may also lead to safety risks during the operation. This is especially true when handling heavy or large-sized stainless steel pipes, which not only reduces work efficiency but may also threaten the health of operators. Utility Model Content

[0008] As a further embodiment of this utility model, a connecting cylinder is fixedly installed on the back of the movable block, the connecting cylinder is connected to the communicating groove, a piston rod is movably installed in the connecting cylinder, a connecting frame is fixedly installed on the right end of the connecting cylinder, a sensing block is fixedly installed on the right end of the connecting frame, a trigger block is fixedly installed on the right end of the piston rod, a spring is fixedly installed between the piston rod and the sensing block, and a scale is provided on the side wall of the connecting frame.

[0009] As a further embodiment of this utility model, the top of the testing platform is provided with a movable groove, in which a threaded rod is movably installed. A drive motor is fixedly installed on the outside of the testing platform, and the output end of the drive motor is fixedly connected to the threaded rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the air compressor is activated by a controller, which pressurizes the outside air into the steel pipe. As the air pressure inside the pipe increases, it pushes the piston rod to the right. When the trigger block at the right end of the piston rod contacts the sensing block, it sends an electrical signal to the controller, which then shuts off the air compressor. When there is a leak in the pipe weld, the air pressure inside the pipe decreases. At this time, a spring pushes the piston rod to the left. When the piston rod moves, it indicates that there is a leak in the pipe weld. This allows for automatic inspection after pipe installation, eliminating the need for workers to turn over the stainless steel pipe for inspection, reducing labor intensity, and avoiding threats to the health of operators.

[0022] Reference Figure 1 - Figure 4An automatic inspection device for stainless steel pipe welds includes an inspection table 1. A fixed block 2 is fixedly installed on the top left side of the inspection table 1, and a movable block 3 is set on the top right side of the inspection table 1. A controller 6 is fixedly installed on the side wall of the inspection table 1. An air compressor 7 is set on the left side of the fixed block 2 and is fixedly installed on the inspection table 1. A sliding groove 11 is opened on the inner side of the fixed block 2 and the movable block 3. V-groove clamps 12 are movably installed at the upper and lower ends of the sliding groove 11. A sealing gasket 9 is fixedly installed on the inner side of the fixed block 2 and the movable block 3. A connecting groove 26 is opened in the middle of the sealing gasket 9 and penetrates the left and right sides of the fixed block 2 and the movable block 3.

[0023] In this embodiment, a rotating rod 17 is movably installed in the slide 11. The threads at both ends of the rotating rod 17 are opposite. The V-groove clamping block 12 is threadedly connected to the rotating rod 17. The top of the rotating rod 17 extends upward through the fixing block 2. A worm gear 13 is fixedly installed on the top of the rotating rod 17. A control rod 14 is provided on the outside of the worm gear 13. A worm 15 is fixedly installed on the control rod 14 at the position corresponding to the worm gear 13. The worm 15 meshes with the worm gear 13. A servo motor 16 is fixedly installed on the outside of the fixing block 2 at the position corresponding to the control rod 14. The output end of the servo motor 16 is fixedly connected to the control rod 14. When the servo motor 16 is started, it drives the control rod 14 to rotate. The worm gear 13 can be controlled to rotate through the worm gear 15 on the control rod 14. The worm gear 13 will drive the rotating rod 17 to rotate. The rotating rod 17 can control the V-groove clamping block 12 to clamp and fix the two sides of the steel pipe in the middle position between the fixing block 2 and the movable block 3.

[0024] In this embodiment, a connecting cylinder 18 is fixedly installed on the back of the movable block 3, and the connecting cylinder 18 is connected to the communicating groove 26. A piston rod 19 is movably installed in the connecting cylinder 18. A connecting frame 20 is fixedly installed on the right end of the connecting cylinder 18, and a sensing block 22 is fixedly installed on the right end of the connecting frame 20. A trigger block 21 is fixedly installed on the right end of the piston rod 19. A spring 23 is fixedly installed between the piston rod 19 and the sensing block 22. A scale 24 is provided on the side wall of the connecting frame 20, and the outside air can be pressurized by the air compression device 7. When the air pressure inside the steel pipe increases, it pushes the piston rod 19 to move to the right. When the trigger block 21 at the right end of the piston rod 19 contacts the sensing block 22, it sends an electrical signal to the controller 6. The controller 6 then shuts off the air compressor 7. When there is a leak in the pipe weld, the air pressure inside the pipe will decrease. At this time, the spring 23 will push the piston rod 19 to the left. When the position of the piston rod 19 moves, it means that there is a leak in the pipe weld. When the position of the piston rod 19 does not change, it means that the pipe weld is qualified.

[0025] In this embodiment, the top of the testing platform 1 is provided with a movable groove 4, in which a threaded rod 5 is movably installed. A drive motor 10 is fixedly installed on the outside of the testing platform 1, and the output end of the drive motor 10 is fixedly connected to the threaded rod 5. A connecting block 25 is fixedly installed at the bottom of the movable block 3, and the connecting block 25 is threadedly connected to the threaded rod 5. The drive motor 10 is started by the controller 6, and the drive motor 10 can drive the threaded rod 5 to rotate. The threaded rod 5 can control the movable block 3 to move towards the steel pipe. The fixed block 2 and the movable block 3 cooperate to hold the two sides of the steel pipe in place.

[0026] In this embodiment, the output end of the air compressor 7 is connected to the connecting groove 26 on the back of the fixed block 2. A one-way valve 8 is fixedly installed between the output end of the air compressor 7 and the connecting groove 26. The one-way valve 8 can prevent the high-pressure air in the pipeline from flowing back and leaking.

[0027] In this embodiment, rollers 27 are movably mounted on the clamping surface of the V-groove clamping block 12. The rollers 27 enable the steel pipe to move back and forth between the fixed block 2 and the movable block 3 after being clamped by the V-groove clamping block 12.

[0028] From the above description, it can be seen that the above-described embodiments of this utility model achieve the following technical effects: In use, the steel pipe with weld seam that needs to be inspected is moved between the fixed block 2 and the movable block 3 by the lifting frame, and then the drive motor 10 is started by the controller 6. The drive motor 10 can drive the threaded rod 5 to rotate, and the threaded rod 5 can control the movable block 3 to move towards the steel pipe. The fixed block 2 and the movable block 3 cooperate to hold the two sides of the steel pipe. Then, the servo motor 16 is started to drive the control rod 14 to rotate. The worm gear 15 on the control rod 14 can control the worm wheel 13 to rotate. The worm wheel 13 will drive the rotating rod 17 to rotate. The rotating rod 17 can control the V-groove clamping block 12 to clamp and fix the two sides of the steel pipe in the middle position between the fixed block 2 and the movable block 3. Then, the drive motor 10 is started again to drive the movable block 3 to move. At this time, the connecting groove 26 on the fixed block 2 and the movable block 3 will be close to both ends of the steel pipe, sealing both ends of the steel pipe. The roller 27 can make the steel pipe move back and forth between the fixed block 2 and the movable block 3 after being clamped by the V-groove clamping block 12.

[0029] Subsequently, the air compressor 7 is activated by the controller 6. The air compressor 7 pressurizes the outside air into the steel pipe. As the air pressure inside the steel pipe increases, it pushes the piston rod 19 to move to the right. When the trigger block 21 at the right end of the piston rod 19 contacts the sensing block 22, it sends an electrical signal to the controller 6. The controller 6 then shuts off the air compressor 7. The one-way valve 8 prevents the high-pressure air in the pipeline from flowing back and leaking. After a period of time, the position of the piston rod 19 can be observed. When there is a leak in the pipeline weld, the air pressure inside the pipeline will decrease. At this time, the spring 23 will push the piston rod 19 to the left. When the position of the piston rod 19 moves, it means that there is a leak in the pipeline weld. When the position of the piston rod 19 does not change, it means that the pipeline weld is qualified. This achieves automatic inspection after pipeline installation, eliminating the need for workers to turn over the stainless steel pipe for inspection, reducing labor intensity, and avoiding threats to the health of operators.
