[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The present invention provides a defect detection device for power equipment pipelines. By setting up a drive assembly and two transmission rollers, the drive assembly can drive the two transmission rollers to rotate, thereby enabling the pipeline located above the two transmission rollers to rotate, which facilitates the flaw detector to perform all-round defect detection of the pipeline in the circumference.
[0017] 2. The present invention provides a defect detection device for power equipment pipelines.

[0018] 3. The present invention provides a defect detection device for power equipment pipelines.

Detailed Implementation
[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0029] The present invention provides the following preferred embodiments:
[0030] Example 1, as Figures 1-6 As shown, a defect detection device for power equipment pipelines includes a base 11, a flaw detector 24, a rotating mechanism, and a moving mechanism.
[0031] The rotating mechanism includes a drive assembly and two transmission rollers 12. Four mounting plates 13 are symmetrically mounted on the top of the base 11. Both ends of each transmission roller 12 are hinged to the two mounting plates 13. The drive assembly is located between the two transmission rollers 12. By setting the drive assembly and the two transmission rollers 12, the drive assembly can drive the two transmission rollers 12 to rotate, thereby enabling the pipe above the two transmission rollers 12 to rotate, which facilitates the flaw detector 24 to perform all-round defect detection of the pipe in the circumferential direction.
[0032] The moving mechanism includes a fixed frame 22, a telescopic assembly, and a transmission assembly. The fixed frame 22 is located above the base 11, the flaw detector 24 is mounted on the fixed frame 22, the telescopic assembly is located between the fixed frame 22 and the base 11, and the transmission assembly is located between the telescopic assembly and the drive assembly.
[0033] The telescopic component can drive the fixed frame 22 to move, thereby enabling the flaw detector 24 to move. This facilitates the adjustment of the position of the flaw detector 24, allowing it to move to different positions above the pipeline, thus facilitating defect detection of the pipeline at different locations.
[0034] By setting up a transmission component, the flaw detector 24 can move while the pipeline rotates, thus enabling comprehensive pipeline inspection with a wide inspection range and flexible use.
[0035] like Figures 1-6 As shown, the drive assembly includes a drive belt 15, a motor 23 and two drive wheels 14. The motor 23 is fixed to one side of a mounting plate 13, and the output end of the motor 23 is connected to the end of a drive roller 12. The two drive wheels 14 are respectively fixed to the ends of the two drive rollers 12 away from the motor 23. The drive belt 15 is sleeved on the two drive wheels 14.
[0036] When the pipe needs to be rotated, the control motor 23 works, which drives the transmission roller 12 connected to its output end to rotate. The transmission roller 12 drives a transmission wheel 14 connected to it to rotate. Under the action of the transmission belt 15, the other transmission wheel 14 can be rotated, thereby enabling the other transmission roller 12 to rotate synchronously. By utilizing the friction between the transmission roller 12 and the pipe, the pipe can be rotated, which facilitates the flaw detector 24 to inspect the circumferential surface of the pipe.
[0037] like Figures 1-6 As shown, the telescopic assembly includes a lead screw 18, a first guide rod 19, two sliding seats 16, and two sliders 17. The two sliding seats 16 are symmetrically fixed on both sides of the top of the base 11. The lead screw 18 and the first guide rod 19 are respectively rotatably disposed inside the two sliding seats 16. One slider 17 is sleeved on the lead screw 18 and threadedly engaged with the lead screw 18, and the other slider 17 is sleeved on the first guide rod 19 and slidably connected to the first guide rod 19.
[0038] When the transmission assembly is working, it can drive the lead screw 18 to rotate. Due to the threaded fit between the lead screw 18 and the slider 17, and the sliding connection between the first guide rod 19 and the slider 17, when the lead screw 18 rotates, it can drive the fixed frame 22 to move along the length direction of the sliding seat 16, which in turn can drive the flaw detector 24 to move, making it convenient to adjust the position of the flaw detector 24 and to detect different positions of the pipeline.
[0039] like Figures 1-6 As shown, the transmission assembly includes a first gear 20 and a second gear 21. The first gear 20 is fixed to one end of one of the transmission rollers 12 away from the transmission wheel 14, and the second gear 21 is fixed to one end of the lead screw 18. The first gear 20 and the second gear 21 mesh with each other. A clearance groove is provided on the surface of the base 11, and the second gear 21 is located inside the clearance groove.
[0040] When the transmission roller 12 rotates under the action of the drive assembly, it can drive the first gear 20 to rotate. Since the first gear 20 and the second gear 21 mesh with each other, when the first gear 20 rotates, it can drive the second gear 21 to rotate. When the second gear 21 rotates, it can drive the lead screw 18 to rotate, thereby causing the pipeline to rotate while driving the flaw detector 24 to move, so as to achieve uniform and comprehensive inspection of the pipeline surface.
[0041] like Figures 1-6As shown, two balls 28 are symmetrically arranged on both sides of the fixed frame 22. Each ball 28 is connected to the fixed frame 22 by an adjustment component for moving the ball 28. By setting two adjustment components and two balls 28, the adjustment components can move the balls 28 to the top of the pipe. The balls 28 on both sides can then be used to position the pipe, ensuring its stability and preventing it from detaching from the two drive rollers 12. At the same time, since the balls 28 can roll on the pipe, they will not affect the pipe when the fixed frame 22 moves, thus achieving the positioning effect of the pipe while the fixed frame 22 moves.
[0042] like Figures 1-6 As shown, each adjustment component includes a threaded seat 25, a threaded rod 26, a movable plate 27, and two second guide rods 29. The threaded seat 25 is fixed on the fixed frame 22. The threaded rod 26 is inserted into the inside of the threaded seat 25 and threadedly engaged with the threaded seat 25. One end of the threaded rod 26 is rotatably connected to the movable plate 27 through a bearing. The ball bearing 28 is fixedly installed on the side of the movable plate 27 away from the threaded rod 26. The two second guide rods 29 are symmetrically fixed on one side of the movable plate 27. Each second guide rod 29 is slidably mounted on the fixed frame 22.
[0043] When the pipe needs to be positioned, the threaded rod 26 is rotated. Due to the threaded engagement between the threaded rod 26 and the threaded seat 25, the threaded rod 26 can move when it rotates. When the threaded rod 26 moves, it can drive the moving plate 27 to move, which in turn drives the ball 28 to move. This allows the ball 28 to contact the surface of the pipe, thus limiting the pipe and preventing it from detaching from the two drive rollers 12. This achieves a fixing effect and facilitates the inspection work.
[0044] The beneficial effects of this utility model are specifically reflected in the fact that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
