Therefore, it is necessary to frequently conduct non-destructive detection on the surface of oil and gas pipelines;

[0003] At present, the method for non-destructively detecting oil and gas pipelines is still that workers use detection probes to detect along the surface of the oil and gas pipelines. However, due to the lack of specific adapted tools and in order to ensure the comprehensiveness of detection, it is necessary to conduct a comprehensive detection slowly. The overall workload is large and the detection efficiency is very low. Content of the Utility Model

[0004] In order to solve the above problems; the purpose of the utility model is to provide a non-destructive detection device for oil and gas pipelines.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: a non-destructive detection device for oil and gas pipelines, including a bracket.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0017] Embodiment: As Figures 1-4 shown, the utility model provides a non-destructive testing device for oil and gas pipelines, including a bracket 1. The bracket 1 is integrally arranged in an inverted U shape. One end of the bracket 1 is fixedly provided with four mounting rods 11 arranged in a rectangular distribution. The ends of the four mounting rods 11 away from the bracket 1 are jointly fixedly provided with a first mounting plate 12 arranged in an arc shape. A first detection plate 13 in an arc shape is slidably arranged on the side of the first mounting plate 12 away from the mounting rods 11. A second mounting plate 14 is arranged at the end of the bracket 1 opposite to the first detection plate 13. A second detection plate 15 is slidably arranged on the end of the second mounting plate 14 facing the first detection plate 13. Detection probes 16 are fixedly installed on the inner wall sides of the first detection plate 13 and the second detection plate 15. Sliding plates 17 are fixedly provided on the sides of the first detection plate 13 and the second mounting plate 14 away from the detection probes 16. The sliding plates 17 are integrally arranged in a cross shape. By arranging the sliding plates 17 in a cross shape, the sliding plates 17 can drive the first detection plate 13 and the second detection plate 15 to slide fully on the first mounting plate 12 and the second mounting plate 14. The sliding plates 17 are slidably arranged in the first mounting plate 12 and the second mounting plate 14. A toothed ring 2 is fixedly provided on the side of the sliding plate 17 close to the first mounting plate 12 away from the first detection plate 13. A driving gear 21 meshing with the toothed ring 2 is rotatably arranged inside one end of the bracket 1 close to the first mounting plate 12.

[0018] A toothed plate 22 meshing with the driving gear 21 is arranged at the position of the bracket 1 close to the driving gear 21. A moving plate 23 perpendicular to the toothed plate 22 is fixedly provided on the side of the toothed plate 22 away from the driving gear 21. An activity slot 24 is penetrated and opened on the moving plate 23. A push block 25 is movably inserted in the activity slot 24. A rotating plate 26 is fixedly provided at the end of the push block 25 away from the bracket 1. A rotating shaft 27 is fixedly provided at the end of the rotating plate 26 away from the push block 25. When the rotating shaft 27 continuously pushes the moving plate 23 to drive the driving gear 21 to rotate back and forth through the rotating plate 26 and the push block 25, the driving gear 21 drives the toothed ring 2 meshing with it to rotate back and forth. At this time, the sliding plates 17 and the first detection plate 13 connected to the toothed ring 2 rotate repeatedly. As the bracket 1 moves along the oil and gas pipeline, the repeatedly rotating first detection plate 13 and the second detection plate 15 will increase the detection area of the detection probes 16 on the surface of the oil and gas pipeline; A support plate 29 arranged in a U shape is fixedly provided on the bracket 1 close to the toothed plate 22. A driving motor 28 is fixedly installed on the support plate 29. The output end of the driving motor 28 is coaxially fixedly arranged on the rotating shaft 27. The arranged driving motor 28 can provide power for the rotation of the rotating shaft 27, which is convenient for the staff to operate; Vertical limiting plates 231 are fixedly provided at both ends of the moving plate 23. The limiting plates 231 can be movably inserted on the support plate 29. The arranged limiting plates 231 can enable the moving plate 23 to move stably up and down on the support plate 29.

[0019] One end of the bracket 1 close to the second mounting plate 14 is fixedly installed with a cylinder 3, and the output end of the cylinder 3 is coaxially and fixedly arranged on the second mounting plate 14. The arranged cylinder 3 can push the second mounting plate 14 to move towards the first mounting plate 12, so that the detection probes 16 on the first mounting plate 12 and the second mounting plate 14 are close to the oil and gas pipeline, and better detection can be carried out.

[0020] Two symmetrically arranged clamping blocks 18 are fixedly arranged at the upper and lower ends of the first detection plate 13, and clamping grooves 19 corresponding to the clamping blocks 18 are opened at the upper and lower ends of the second detection plate 15. The arranged clamping blocks 18 can connect the first detection plate 13 and the second detection plate 15, which is convenient for the driving gear 21 to drive the first detection plate 13 to rotate and also drive the second detection plate 15 to rotate together subsequently.

[0021] Universal wheels 4 are installed at the bottom of both ends of the bracket 1. The arranged universal wheels 4 can facilitate the staff to push the whole bracket 1 to move along the oil and gas pipeline for detection.

[0022] Working principle: When in use, the staff first sleeved the bracket 1 on the oil and gas pipeline to be detected, adjusted the first detection plate 13 to be close to the oil and gas pipeline, and then the cylinder 3 pushed the second detection plate 15 on the second mounting plate 14 to be close to the first detection plate 13, so that the first detection plate 13 and the second detection plate 15 were combined, making the detection probe 16 better detect the oil and gas pipeline. After combination, the clamping block 18 on the first detection plate 13 will be inserted into the clamping groove 19 on the second detection plate 15, making the first detection plate 13 and the second detection plate 15 synchronously connected. At this time, the driving motor 28 can drive the rotating shaft 27 to rotate. When the rotating shaft 27 rotates, at this time the rotating shaft 27 will drive the rotating plate 26 and the pushing block 25 to continuously rotate. The rotating pushing block 25 will continuously move from one end of the movable groove 24 to the other end, so that the pushing block 25 will continuously push the moving plate 23 to move up and down repeatedly. Thus, the moving plate 23 will drive the arranged toothed plate 22 to move up and down continuously, driving the driving gear 21 to rotate back and forth continuously. As a result, the driving gear 21 drives the toothed ring 2 meshed with it to rotate back and forth. At this time, the sliding plate 17 and the first detection plate 13 connected to the toothed ring 2 rotate repeatedly. As the bracket 1 moves along the oil and gas pipeline, the repeatedly rotating first detection plate 13 and the second detection plate 15 will increase the detection area of the detection probe 16 on the surface of the oil and gas pipeline, better and more comprehensively detect the oil and gas pipeline, improve the detection efficiency, and at the same time greatly reduce the labor intensity of the staff.

[0023] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
