Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline inspection track technology, specifically to a steel strip track for pipeline inspection. Background Technology
[0002] In the manufacturing, installation, and operation and maintenance of industrial pipelines (such as oil, natural gas, chemical, and municipal pipelines), the quality inspection of circumferential welds is a crucial step in ensuring the safe operation of the pipeline system. Among these technologies, ultrasonic testing is widely used in the non-destructive testing of pipeline welds due to its advantages of being radiation-free, highly sensitive, and capable of detecting linear defects such as cracks.
[0003] To achieve comprehensive inspection of circumferential welds in pipelines, the ultrasonic detector needs to move continuously and stably in a circular motion along the pipeline circumference to ensure the continuity of the detection signal and data integrity. To drive the ultrasonic detector across the pipeline surface, the industry has developed track-based inspection devices. These devices utilize a circular steel track laid outside the pipeline, allowing the ultrasonic detector mounted on the track to move in a circular motion, achieving automated movement. Existing steel track systems mostly employ rigid metal rings or spliced frame structures. While these can ensure movement stability to a certain extent, the rigid structure is difficult to adapt to pipelines of different diameters. For inspection scenarios with a large range of pipe diameter variations, multiple sets of tracks of different specifications are required, increasing equipment costs and making the equipment inconvenient to carry. Utility Model Content
[0004] This invention proposes a steel strip track for pipeline inspection, which solves the problem that existing ultrasonic inspection tracks have low applicability to pipelines of different diameters.
[0005] The technical solution of this utility model is as follows: A steel strip track for pipeline inspection includes an annular track, a support ring, a positioning mechanism, a movable seat, a moving mechanism, and an ultrasonic detector. The support ring is fixedly disposed at one end of the annular track. The positioning mechanism is disposed on the support ring and is used to position the support ring and the pipeline. The movable seat is disposed on one side of the annular track. A moving groove is formed on the side wall of the movable seat. The annular track extends into the moving groove and allows the movable seat to move in annular motion on the surface of the annular track. The moving mechanism is disposed on the movable seat and is used to drive the movable seat to move on the surface of the annular track. The ultrasonic detector is fixedly disposed on the movable seat and is used to detect defects on the surface of the pipeline.
[0006] Preferably, the positioning mechanism includes a support port, a support block, and a position adjustment mechanism. The support ring has multiple support ports. The support block is slidably disposed within the support ports. A clamping head is fixedly disposed at one end of the support block near the annular track. The position adjustment mechanism is disposed between the support ring and the support block for adjusting the position of the support block.
[0007] Furthermore, the position adjustment mechanism includes a first adjustment groove, a second adjustment groove, and a synchronous rotation mechanism. The first adjustment groove is provided on the side wall of the support block, and a first rack is fixedly provided at the bottom of the first adjustment groove. The second adjustment groove is provided on the side wall of the first adjustment groove, and a first gear is rotatably provided in the second adjustment groove. The first gear meshes with the first rack. The synchronous rotation mechanism is provided on the support ring and is used to drive multiple first gears to rotate synchronously.
[0008] Furthermore, the synchronous rotation mechanism includes a first cavity, a second gear ring, and a drive mechanism. The support ring has an annular first cavity. A second gear is rotatably disposed in the first cavity on one side of the first gear. A connecting rod is fixedly disposed between the second gear and the adjacent first gear. The second gear ring is rotatably disposed in the first cavity and meshes with the second gear. The drive mechanism is disposed on the support ring and is used to drive the first gear to rotate.
[0009] Furthermore, the drive mechanism includes a first motor and a drive rod. The first motor is mounted on the side wall of the support ring, and the drive rod is fixedly disposed between the output end of the first motor and the adjacent first gear.
[0010] Based on the above scheme, the moving mechanism includes a moving groove, an annular groove, a second motor, and a battery. The moving groove is formed on the side wall of the moving groove, and a third gear is rotatably arranged inside the moving groove. The annular groove is formed on the side wall of the annular track, and a third toothed ring is fixedly arranged at the bottom of the annular groove. The third toothed ring meshes with the third gear. The second motor is mounted on the moving base, and the output end of the second motor is fixedly connected to the third gear. The battery is fixedly arranged on the moving base, and the battery is electrically connected to the second motor and the ultrasonic detector.
[0011] The working principle and beneficial effects of this utility model are as follows: 1. In this utility model, by setting up a positioning mechanism, the operation of the first motor can drive one of the first gears and the second gear to rotate. At the same time, the meshing of the second gear with the second gear ring drives multiple second gears and the first gear to rotate synchronously. Then, the meshing of the first gear with the first rack drives multiple support blocks to move synchronously. Thus, the movement of the support blocks can drive the clamping head to abut against the outer wall of the pipe, thereby facilitating the fixing of the support ring and the annular track on the surface of the pipe. 2. In this utility model, by setting up a moving mechanism, the operation of the second motor can drive the third gear to rotate. At the same time, the meshing of the third gear with the third gear ring drives the moving seat and the ultrasonic detector to move on the surface of the ring track, thereby facilitating the detection of pipeline quality by the ultrasonic detector.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0016] like Figures 1-6 As shown, this embodiment proposes a steel strip track for pipeline inspection, including an annular track 1, a support ring 2, a positioning mechanism, a movable seat 3, a moving mechanism, and an ultrasonic testing head. The support ring 2 is fixedly disposed at one end of the annular track 1. The positioning mechanism is disposed on the support ring 2 for positioning the support ring 2 and the pipeline. The movable seat 3 is disposed on one side of the annular track 1. A moving groove 4 is provided on the side wall of the movable seat 3. The annular track 1 extends into the moving groove 4 and allows the movable seat 3 to move in annular motion on the surface of the annular track 1. The moving mechanism is disposed on the movable seat 3 for driving the movable seat 3 to move on the surface of the annular track 1. The ultrasonic testing head is fixedly disposed on the movable seat 3 for detecting defects on the pipeline surface.
[0017] Reference Figures 1-6 The positioning mechanism includes a support port, a support block 6, and a position adjustment mechanism. Multiple support ports are provided on the support ring 2. The support block 6 is slidably disposed within the support ports. A clamping head 7 is fixedly disposed at one end of the support block 6 near the annular track 1. The position adjustment mechanism is disposed between the support ring 2 and the support block 6 to adjust the position of the support block 6. The position adjustment mechanism includes a first adjustment groove 8, a second adjustment groove, and a synchronous rotation mechanism. A first adjustment groove 8 is provided on the side wall of the support block 6, and a first rack 9 is fixedly disposed at the bottom of the first adjustment groove 8. A second adjustment groove is provided on the side wall of the first adjustment groove 8, and a first gear 10 is rotatably disposed within the second adjustment groove, meshing with the first rack 9. The synchronous rotation mechanism is disposed on the support ring 2 to drive multiple first gears 10 to rotate synchronously. The synchronous rotation mechanism includes a first cavity 11, a second gear ring 13, and a drive mechanism. An annular first cavity 11 is provided inside the support ring 2, and a clamping head 7 is rotatably disposed on one side of the first gear 10 within the first cavity 11. The second gear 12 is fixedly connected to the adjacent first gear 10 by a connecting rod. The second gear ring 13 is rotatably disposed in the first cavity 11 and meshes with the second gear 12. The drive mechanism is disposed on the support ring 2 and is used to drive the first gear 10 to rotate. The drive mechanism includes a first motor 14 and a drive rod. The first motor 14 is mounted on the side wall of the support ring 2, and the drive rod is fixedly disposed between the output end of the first motor 14 and the adjacent first gear 10. Specifically, the operation of the first motor 14 can drive one of the first gears 10 and the second gear 12 to rotate. At the same time, the meshing of the second gear 12 with the second gear ring 13 drives multiple second gears 12 and the first gear 10 to rotate synchronously. Then, the meshing of the first gear 10 with the first rack 9 drives multiple support blocks 6 to move synchronously. Thus, the movement of the support blocks 6 can drive the clamping head 7 to abut against the outer wall of the pipe, thereby facilitating the fixation of the support ring 2 and the annular track 1 on the pipe surface.
[0018] Reference Figures 1-4 The moving mechanism includes a moving groove, an annular groove 16, a second motor 18, and a battery 19. The moving groove is located on the side wall of the moving through groove 4, and a third gear 15 is rotatably installed inside the moving groove.

The third toothed ring 17 meshes with the third gear 15. The second motor 18 is mounted on the moving base 3, and the output end of the second motor 18 is fixedly connected to the third gear 15. The battery 19 is fixedly installed on the moving base 3 and electrically connected to the second motor 18. Specifically, the operation of the second motor 18 can drive the third gear 15 to rotate. At the same time, the meshing of the third gear 15 and the third toothed ring 17 drives the moving base 3 and the ultrasonic detector 5 to move on the surface of the annular track 1, thereby facilitating the detection of pipeline quality by the ultrasonic detector 5.
[0019] In this embodiment, during use, the operator supports the pipe with a bracket, then places the support ring 2 on the pipe and aligns the ultrasonic detector 5 with the pipe weld. The operator then controls the first motor 14, which drives one of the first gears 10 and the second gear 12 to rotate. Simultaneously, the meshing of the second gear 12 with the second gear ring 13 drives multiple second gears 12 and the first gear 10 to rotate synchronously. Furthermore, the meshing of the first gear 10 with the first rack 9 drives multiple support blocks 6 to move synchronously. This movement of the support blocks 6 causes the clamping head 7 to abut against the outer wall of the pipe, facilitating the fixation of the support ring 2 and the annular track 1 on the pipe surface. The operator then controls the second motor 18, which drives the third gear 15 to rotate. Simultaneously, the meshing of the third gear 15 with the third gear ring 17 moves the moving seat 3 and the ultrasonic detector 5 on the surface of the annular track 1, facilitating the inspection of the pipe quality using the ultrasonic detector 5.
