[0001] This utility model is a pipeline weld flaw detection drive device, belonging to the field of pipeline weld flaw detection technology. Background Technology

[0002] With the development of modern industry, the requirements for the safety and reliability of pipelines are becoming increasingly stringent. Traditional manual operation methods are insufficient to meet the demands of large-scale, high-precision weld inspection. Therefore, more automated pipeline weld inspection drive devices have emerged. These devices not only improve inspection efficiency but also reduce the impact of human factors, ensuring the consistency and accuracy of results. Pipeline inspection is mainly used for non-destructive testing of welds, corrosion, and cracks in pipelines in industries such as petroleum, chemical, and power. During the inspection process, drive devices are typically required to move and rotate the pipeline.

[0003] However, traditional flaw detection devices are often large and heavy, and the process of handling and installing them is cumbersome, requiring multiple workers to work together, which increases labor intensity, prolongs preparation time, and is not conducive to rapid response to emergency tasks. There is an urgent need for a pipeline weld flaw detection drive device to solve the above problems. Utility Model Content

This utility model designs an assembled pipeline weld flaw detection structure, which is convenient for workers to handle and install, and can also drive flaw detection operations on pipelines, which is quick and convenient.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a pipe weld flaw detection driving device, comprising a horizontal base plate, an arc-shaped fixed seat, a flaw detection driving outer ring, and a flaw detection driving inner ring. Second limiting cylinders are longitudinally fixed to the left and right sides of the upper end of the horizontal base plate, and a first limiting cylinder is fixed to the middle of the upper end of the horizontal base plate. A support leg is fixed to the lower outer end of the arc-shaped fixed seat, and a first positioning rod is fixed to the middle of the lower end of the arc-shaped fixed seat.

The plate has two adjusting plates, each with an electric telescopic rod mounted longitudinally at its upper end. Each of the two electric telescopic rods has an arc-shaped support plate mounted longitudinally at its upper end. The outer ring of the flaw detection drive is longitudinally fixed to the arc-shaped fixing seat by multiple bolts. A rotating groove is formed on the inner side of the outer ring, and annular slide rails are fixed to both the left and right ends of the rotating groove. The inner ring of the flaw detection drive is located within the rotating groove and slides between the two annular slide rails. A mounting cylinder is fixed to the rear end of the inner ring of the flaw detection drive. A flaw detection head is mounted inside the mounting cylinder by bolts. An annular toothed groove is formed on the annular side of the inner ring of the flaw detection drive. A small servo motor is mounted on the upper right end of the outer ring of the flaw detection drive.

[0006] Furthermore, the support leg is mounted on the outside of the horizontal base plate.

[0007] Furthermore, the lower ends of the two second positioning rods are respectively inserted into the two second limiting cylinders, while the lower end of the first positioning rod is located inside the first limiting cylinder.

[0008] Furthermore, the outer ring of the flaw detection drive has a gear groove at its upper end, and a spur gear is movably arranged in the gear groove. The shaft end of the small servo motor is fixed to the spur gear.

[0009] Furthermore, the lower end of the spur gear meshes with the tooth friction groove of the annular tooth.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3This utility model provides a technical solution: a pipe weld flaw detection driving device, including a horizontal base plate 1, an arc-shaped fixed seat 6, a flaw detection driving outer ring 11, and a flaw detection driving inner ring 12. Second limiting cylinders 3 are longitudinally fixed to the left and right sides of the upper end of the horizontal base plate 1, and a first limiting cylinder 2 is fixed to the middle of the upper end of the horizontal base plate 1. Support legs 4 are fixed to the lower outer end of the arc-shaped fixed seat 6, and a first positioning rod 5 is fixed to the middle of the lower end of the arc-shaped fixed seat 6. Horizontal hollow plates 8 are horizontally fixed to both the left and right ends of the arc-shaped fixed seat 6. Second positioning rods 7 are longitudinally fixed to the lower ends of both horizontal hollow plates 8. Adjusting plates 9 are horizontally fixed to both horizontal hollow plates 8 by bolts. Electric telescopic rods 19 are longitudinally installed on the upper ends of both adjusting plates 9, and arc-shaped supports are longitudinally installed on the upper ends of both electric telescopic rods 19. The support plate 10 and the outer ring 11 of the flaw detection drive are longitudinally fixed in the arc-shaped fixing seat 6 by multiple bolts. The inner side of the outer ring 11 of the flaw detection drive has a rotating groove, and the left and right ends of the rotating groove are fixed with annular slide rails 13. The inner ring 12 of the flaw detection drive is located in the rotating groove and slides between the two annular slide rails 13. The rear end of the inner side of the inner ring 12 of the flaw detection drive is fixed with a mounting cylinder 17. The flaw detection head 18 is installed in the mounting cylinder 17 by bolts. The annular side of the inner ring 12 of the flaw detection drive has an annular toothed groove 14. A small servo motor 15 is installed on the upper right side of the outer ring 11 of the flaw detection drive. This design solves the problem that traditional flaw detection devices are often large and heavy, and the transportation and installation process is cumbersome, requiring multiple workers to cooperate to complete the task, which increases labor intensity and extends preparation time.

[0019] As the first embodiment of this utility model: the support leg 4 is locked outside the horizontal base plate 1, and the added support leg 4 can provide auxiliary support for the arc-shaped fixed seat 6. The lower ends of the two second positioning rods 7 are respectively inserted into the two second limiting cylinders 3, and the lower end of the first positioning rod 5 is located in the first limiting cylinder 2. By adding the two second positioning rods 7, the lower ends of the two second limiting cylinders 3 are respectively inserted into the two second limiting cylinders 3, and the lower end of the first positioning rod 5 is located in the first limiting cylinder 2, which can ensure the stability of the arc-shaped fixed seat 6 on the upper side of the horizontal base plate 1. The upper end of the flaw detection drive outer ring 11 is provided with a gear groove, and a spur gear 16 is movably arranged in the gear groove. The shaft end of the small servo motor 15 is fixed to the spur gear 16, and the lower end of the spur gear 16 meshes with the annular toothed groove 14. By adding the lower end of the spur gear 16 meshing with the annular toothed groove 14, the rotation of the spur gear 16 can drive the annular toothed groove 14 to mesh and rotate, forcing the flaw detection drive inner ring 12 to rotate as well.

[0020] The small servo motor 15, the flaw detection head 18, and the two electric telescopic rods 19 are all connected to an external PLC controller via wires. The operation of the small servo motor 15, the flaw detection head 18, and the two electric telescopic rods 19 can be controlled by the added external PLC controller.

[0021] As a second embodiment of this utility model: During assembly and use, the support leg 4 is clamped outside the horizontal base plate 1, so that the lower ends of the two second positioning rods 7 are respectively inserted into the two second limiting cylinders 3, and the lower end of the first positioning rod 5 is in the first limiting cylinder 2. Then, the two adjusting plates 9 are horizontally fixed in the two horizontal hollow plates 8 by bolts. Then, the flaw detection drive outer ring 11 is longitudinally fixed in the arc-shaped fixing seat 6 by multiple bolts to complete the assembly. Next, the pipe is passed through the flaw detection drive outer ring 11 and placed on the two arc-shaped support plates 10, so that the flaw detection part of the pipe weld is in the flaw detection drive inner ring 12. Then, the two electric telescopic rods 19 are controlled by an external PLC controller to extend upwards synchronously. The two arc-shaped support plates 10 can then drive the pipe to adjust its height until the center of the pipe coincides with the center of the outer ring 11 of the flaw detection drive. Then, the small servo motor 15 is started, which drives the spur gear 16 to rotate. The spur gear 16 will mesh with the annular toothed groove 14, causing the inner ring 12 of the flaw detection drive to rotate between the two annular slide rails 13. This allows the flaw detection head 18 to rotate in the circumferential direction, thereby performing annular flaw detection on the flaw detection part of the pipe weld.
