[0001] This invention belongs to the technical field of pipeline non-destructive testing technology, specifically relating to a multifunctional fully automatic ultrasonic scanning device. Background Technology

[0002] In the field of pipeline non-destructive testing technology, ultrasonic testing is widely used due to its advantages such as high precision and deep penetration.

[0007] Preferably, a steering gear is engaged on one side of the lower end of the double-sided toothed belt, and the other side of the double-sided toothed belt and the steering gear are engaged with two adjusting slides respectively. Limiting shafts are rotatably connected to both the upper and lower sides of the inner end of the positioning clamp.

[0008] Preferably, the upper end of the double-sided toothed belt is internally engaged with an adjusting gear, the rear end of the adjusting gear is connected to a telescopic connecting rod, the rear end of the telescopic connecting rod is connected to a limiting head, and the rear ends of the telescopic connecting rod and the limiting head are externally sleeved with adjusting rotating heads.

[0009] Preferably, the front end of the adjustment head engages with the outer wall of the rear frame, a locking spring is provided between the limiting head and the inner wall of the front end of the adjustment head, and the telescopic link and the limiting head are elastically connected inside the adjustment head through the locking spring.

[0010] Preferably, the telescopic sweeping assembly includes a drive motor, the drive motor is disposed inside the circumferential moving seat, the front end of the drive motor is rotatably connected to a circumferential moving gear through a motor shaft, and the circumferential moving gear meshes with the front frame, and the front end of the circumferential moving gear is connected to a linkage helical gear.

[0011] Preferably, the linkage helical gear is located on the front side of the front frame, and an axial slide is connected to the middle of the lower end of the circumferential moving seat. An axial slide groove is opened at the lower end of the axial slide groove, and a belt groove is connected to the upper end of the axial slide groove. A drive belt is rotatably connected inside the belt groove.

[0012] Preferably, tensioning shafts are engaged inside both ends of the drive belt, and the upper end of the tensioning shaft on the front side is connected to a reversing helical gear via a connecting shaft. The reversing helical gear is located on the front side of the upper end of the axial slide and engages with the linkage helical gear.

[0013] Preferably, the drive belt is externally connected to a reciprocating push rod, and the lower end of the reciprocating push rod protrudes into the axial slide groove. An upper telescopic rod is slidably connected inside the axial slide groove. A reciprocating push groove is opened at the middle of the upper end of the upper telescopic rod, and the reciprocating push rod is inserted into the reciprocating push groove.

[0014] Preferably, a middle telescopic rod is slidably connected inside the lower end of the reciprocating push groove, and a lower telescopic rod is slidably connected inside the lower end of the middle telescopic rod. The lower telescopic rod is connected to the center of the upper end of the probe frame. A fitting spring is provided at the upper end of the lower telescopic rod, and the fitting spring is located inside the upper telescopic rod and the middle telescopic rod.

[0015] Compared with the prior art, the present invention provides a multifunctional fully automatic ultrasonic scanning device, which has the following beneficial effects: 1. This invention synchronously drives two adjusting slide plates and positioning clamps to move in opposite directions through the adjusting component, which can automatically adapt to and clamp test pipes of different diameters. It can not only accurately fix the pipe at the central axis of the test frame to ensure that the distance between the probe frame and the pipe is consistent to ensure the test accuracy, but also maintain the clamping stability through the locking structure, thereby improving the applicability of the device.

[0016] 2. The probe holder of this invention, through the elastic support of upper, middle and lower multi-stage telescopic rods and internal fitting springs, can adaptively and tightly fit the outer wall of pipes of different diameters. This ensures that the probe and the pipe surface always maintain a constant optimal detection distance, thereby guaranteeing the stability and accuracy of the detection signal. It also buffers the hard contact between the equipment and the pipe, protecting the probe and adapting to the slight deformation of the pipe.

[0017] 3. This invention uses a set of drive motors to simultaneously drive a circumferential moving gear and a reciprocating sweeping mechanism composed of a helical gear set and an elliptical rectangular drive belt. This combines the uniform movement of the probe in the circumferential direction of the pipe with the back-and-forth reciprocating sweeping in the axial direction, thus upgrading the traditional circumferential linear scanning to a highly efficient circumferential surface scanning, expanding the scanning coverage area of ​​a single run, and thereby improving detection efficiency.

[0018] 4. The present invention provides circumferential rollers on both sides of the lower end of the probe frame and embeds axial balls in the rollers. When the probe frame moves on the pipe surface, it relies on the rollers to roll in the circumferential direction and the balls to roll in the axial sweeping direction. This transforms the sliding friction between the probe frame and the pipe surface into rolling friction, reducing wear during movement, protecting the pipe surface and extending the service life of the device itself.

[0019] 5. This invention ensures that the probe frame completes a complete back-and-forth scanning cycle for every rotation of the circumference of the circumference of the linkage helical gear and the direction-changing helical gear, as well as the circumference ratio of the drive belt and the tensioning shaft, thus forming a precise and coordinated scanning trajectory. Furthermore, by precisely matching the ratio of the circumference ... Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] This invention provides, for example Figures 1-9The multifunctional fully automatic ultrasonic scanning device shown includes a rear frame 1 and a front frame 2 positioned directly in front of the rear frame 1. Both the rear frame 1 and the front frame 2 are arc-shaped. Connecting slides 3 are connected to the left and right sides of the lower ends of the rear frame 1 and the front frame 2. Adjustment slides 4 are slidably connected inside the two connecting slides 3. Positioning clamps 5 are connected to the inner ends of the two adjustment slides 4, and the two positioning clamps 5 are located on the left and right sides of the central axis of the arc of the rear frame 1 and the front frame 2, respectively. A circumferential moving seat 6 is engaged between the rear frame 1 and the front frame 2. A probe frame 7 is connected to the lower side of the circumferential moving seat 6. A probe head 33 is bolted to the lower end of the probe frame 7 and electrically connected to an external analysis device via a wiring harness. Circumferential rollers 34 are rotatably connected to the lower left and right sides of the probe frame 7. Multiple axial balls are arranged inside the cylindrical outer walls of the two circumferential rollers 34. 35. The rear frame 1 is equipped with an adjustment component, and the two adjustment slides 4 and the positioning clamps 5 can be adjusted and clamped on the outside of the test pipe through the adjustment component. A telescopic sweeping component is provided between the circumferential moving seat 6 and the probe frame 7, and the probe frame 7 can be adjusted to fit tightly against the outside of the test pipe through the sweeping telescopic component, and can sweep back and forth on the outside of the test pipe through the sweeping telescopic component. During the ultrasonic testing of the test pipe, the rear frame 1 and the front frame 2 are connected into a whole through the connecting slides 3 on both sides to form a test frame. The test frame is placed outside the test pipe, and the adjustment slide 4 is controlled to slide inside the box through the adjustment component, so that the two positioning clamps 5 are clamped on the outside of the test pipe, thereby fixing the test pipe at the central axis of the test frame. At the same time, the probe frame 7 adaptively fits against the outside of the test pipe through the telescopic sweeping component.

[0032] At this time, the telescopic sweeping assembly is activated. The telescopic sweeping assembly drives the circumferential moving seat 6 to slide between the rear frame 1 and the front frame 2, and moves along the circumferential direction of the rear frame 1 and the front frame 2. This allows the circumferential moving seat 6 to drive the probe frame 7 to move in the circumferential direction of the pipeline being inspected through the telescopic sweeping assembly, and also drives the probe frame 7 to sweep back and forth in the axial direction of the pipeline being inspected. This allows the telescopic sweeping assembly to convert the linear circumferential scanning of the pipeline by the probe frame 7 into a circumferential surface scanning of the pipeline being inspected, thereby improving the scanning efficiency.

[0033] Furthermore, the probe holder 7 can roll in the circumferential direction of the pipeline being inspected via the circumferential roller 34, and is assisted in rolling by multiple axial balls 35. The probe holder 7 can also roll in the axial direction of the pipeline being inspected via multiple axial balls 35, thereby reducing wear between the probe holder 7 and the pipeline being inspected. At the same time, the probe holder 7 can emit ultrasonic waves and collect reflected echoes through the probe head 33, and the collected reflected waves can be visualized by external analysis equipment, thereby diagnosing the pipeline being inspected. Since the principle of ultrasonic scanning is a publicly available technology, it will not be described in detail here.

[0034] like Figures 2-4As shown, the adjustment assembly includes a double-sided toothed belt 9. An arc-shaped tensioning groove 8 is provided inside the rear frame 1. The double-sided toothed belt 9 is rotatably connected inside the tensioning groove 8. Tensioning gears 10 are internally meshed on the left and right sides of the lower end of the double-sided toothed belt 9. A steering gear 11 is meshed on one side of the lower end of the double-sided toothed belt 9, and the other side of the double-sided toothed belt 9 and the steering gear 11 respectively mesh with two adjustment slides 4. An adjustment gear 12 is internally meshed on the upper end of the double-sided toothed belt 9. A telescopic link 14 is connected to the rear end of wheel 12. A limit head 15 is connected to the rear end of the telescopic link 14. An adjustment head 16 is sleeved on the outer side of the rear ends of the telescopic link 14 and the limit head 15. A limit groove and a limit strip are provided between the limit head 15 and the adjustment head 16. The front end of the adjustment head 16 engages with the outer wall of the rear frame 1. A locking spring 17 is provided between the inner wall of the front end of the limit head 15 and the adjustment head 16. The telescopic link 14 and the limit head 15 are connected by a lock. The spring 17 is elastically connected inside the adjusting head 16. During the adjustment of the positions of the two positioning clamps 5, the position of the two adjusting slide plates 4 is adjusted synchronously by the rotation of the adjusting head 16, and the two positioning clamps 5 are adjusted synchronously by the adjusting slide plates 4. Since the limiting head 15 and the adjusting head 16 are provided with limiting grooves and limiting strips, the limiting head 15 can only slide back and forth inside the adjusting head 16 and will rotate with the adjusting head 16. Pulling the adjusting head 16 backward, the adjusting head 16 slides backward outside the telescopic link 14 and the limiting head 15, so that the locking teeth at the front end of the adjusting head 16 separate from the tooth groove on the outer wall of the rear end of the rear frame 1. Then the adjusting head 16 is rotated. The adjusting head 16 drives the adjusting gear 12 to rotate inside the upper end of the double-sided toothed belt 9 through the telescopic link 14 and the limiting head 15, and drives the double-sided toothed belt 9 to rotate inside the tensioning groove 8.

[0035] At this time, the double-sided toothed belt 9 restricts its position and tightness through the tensioning groove 8 and the tensioning gears 10 on both sides of the lower end, and drives the steering gear 11 to rotate in the opposite direction through meshing. This allows the double-sided toothed belt 9 to drive the two adjusting slides 4 to slide in opposite directions through the meshing between the lower side of one side and the adjusting slide 4, and the meshing between the steering gear 11 and the other adjusting slide 4. This allows the two adjusting slides 4 to drive the positioning clamps 5 to move closer to or further away from the detection pipe at the same time, thereby realizing the clamping and releasing of the detection pipe by the two positioning clamps 5, and clamping the detection pipe at the central axis of the detection frame. The two positioning clamps 5 can clamp and fix detection pipes of different diameters, which can ensure that the distance between the detection frame and the detection pipe is the same, and ensure that the circumferential moving seat 6 can drive the probe frame 7 to move at a uniform speed in the circumferential direction of the detection pipe, thereby improving the detection accuracy and expanding the applicability of the detection frame.

[0036] In addition, after the positions of the two positioning clamps 5 are adjusted, the locking teeth at the front end of the adjusting head 16 can engage and lock with the tooth groove on the outer wall of the rear end of the rear frame 1 again under the action of the locking spring 17, so as to prevent the adjusting head 16 from rotating accidentally and ensure the stability of the position of the positioning clamps 5.

[0037] like Figure 5 and Figure 9 As shown, the telescopic sweeping assembly includes a drive motor 18. The drive motor 18 is housed inside the circumferential moving base 6, and is electrically connected to an external control button via a wiring harness. The control button controls the start, stop, and speed of the drive motor 18, and can control its forward and reverse rotation. A circumferential moving gear 19 is rotatably connected to the front end of the drive motor 18 via a motor shaft, and the circumferential moving gear 19 meshes with the front frame 2. An axial slide block 21 is connected to the lower middle of the circumferential moving base 6. An axial groove 22 is formed at the lower end of the axial slide block 21, and an upper telescopic rod 28 is slidably connected inside the axial groove 22. A middle telescopic rod 30 is slidably connected inside the lower end of the reciprocating push groove 29, and a lower telescopic rod 31 is slidably connected inside the lower end of the middle telescopic rod 30. The lower telescopic rod 31 is connected to the upper center of the probe frame 7, and a contact spring 32 is provided at the upper end of the lower telescopic rod 31. Inside the telescopic rod 28 and the middle telescopic rod 30, the upper and lower sides of the inner end of the positioning clamp 5 are rotatably connected to the limiting pins 13. During the process of the probe frame 7 adaptively fitting onto the detection pipe, the two positioning clamps 5 can be symmetrically clamped onto the outside of the detection pipe through the two limiting pins 13, thereby fixing the position of the detection frame and the detection pipe, and pushing the probe frame 7 in this process. The position of the probe frame 7 between the detection frame and the detection pipe is adjusted by the sliding of the lower telescopic rod 31 inside the middle telescopic rod 30 and the sliding of the middle telescopic rod 30 inside the upper telescopic rod 28. It is tightly fitted onto the outer wall of the detection pipe by the elastic support of the fitting spring 32, so that the probe frame 7 can adaptively fit onto the outside of the detection pipe with different pipe diameters. This ensures that the probe head 33 inside the lower end of the probe frame 7 and the detection pipe always maintain a stable distance, ensuring detection accuracy, and also improves the applicability of the probe frame 7.

[0038] like Figures 6-8As shown, the front end of the circumferential moving gear 19 is connected to a linkage helical gear 20, which is located on the front side of the front frame 2. The upper end of the axial slide groove 22 is connected to a groove 23, and a drive belt 24 is rotatably connected inside the groove 23. Tensioning shafts 25 are meshed inside both the front and rear ends of the drive belt 24. The upper end of the tensioning shaft 25 on the front side is connected to a reversing helical gear 26 through a connecting shaft. The reversing helical gear 26 is located on the front side of the upper end of the axial slide block 21 and meshes with the linkage helical gear 20. A reciprocating push rod 27 is connected to the outside of the drive belt 24, and the lower end of the reciprocating push rod 27 protrudes inside the axial slide groove 22. A reciprocating push groove 2 is opened in the middle of the upper end of the upper telescopic rod 28. 9. The reciprocating push rod 27 is inserted into the reciprocating push groove 29. During the process of the probe frame 7 scanning the circumferential surface of the detection pipe, the drive motor 18 is started by the control button. The drive motor 18 drives the circumferential moving gear 19 and the linkage helical gear 20 to rotate simultaneously through the motor shaft. At this time, the circumferential moving gear 19 meshes with the toothed groove opened on the front side of the outer end of the front frame 2 and rolls inside the toothed groove through meshing, thereby driving the circumferential moving seat 6 to move along the circumferential direction of the rear frame 1 and the front frame 2. The circumferential moving seat 6 drives the probe frame 7 to move on the outer wall of the detection pipe through the axial slide 21, the upper telescopic rod 28, the middle telescopic rod 30 and the lower telescopic rod 31.

[0039] Meanwhile, the drive motor 18 drives the front tensioning shaft 25 to rotate through the meshing between the linkage helical gear 20 and the reversing helical gear 26, and drives the drive belt 24 to rotate inside the belt groove 23 through the tensioning shaft 25. The drive belt 24 can be kept taut through the two tensioning shafts 25. When the drive belt 24 rotates inside the belt groove 23, the drive belt 24 drives the reciprocating push rod 27 to rotate inside the axial sliding groove 22, and drives the upper telescopic rod 28 to slide back and forth through the reciprocating push groove 29, thereby driving the probe frame 7 to slide back and forth in the axial direction on the outer wall of the detection pipe.

[0040] Since both the groove 23 and the drive belt 24 are elliptical rectangles, and the reciprocating push rod 27 can slide left and right inside the reciprocating push groove 29, the reciprocating push rod 27 can drive the upper telescopic rod 28 to continuously reciprocate back and forth inside the axial sliding groove 22, thereby enabling the probe frame 7 to scan the circumferential surface outside the detection pipe, increasing the detection area and improving detection efficiency.

[0041] Furthermore, the circumference ratio between the linkage helical gear 20 and the reversing helical gear 26 is equal to the circumference ratio between the drive belt 24 and the tensioning shaft 25. When the circumferential moving gear 19 rotates once, it can just drive the drive belt 24 to rotate once. When the circumferential moving gear 19 rotates once, the drive belt 24 can just drive the probe frame 7 to perform a back-and-forth reciprocating motion through the reciprocating push rod 27, the upper telescopic rod 28, the reciprocating push groove 29, the middle telescopic rod 30, and the lower telescopic rod 31, completing one back-and-forth scan. At the same time, since the radius of the circle where the probe head 33 is located is definitely smaller than the radius of the circle where the circumferential moving gear 19 is located, and the circumference of the circumferential moving gear 19 is less than half the left and right width of the probe head 33, the movement distance of the probe head 33 in the circumferential direction of the detected pipeline is definitely less than half the left and right width of the probe head 33. Therefore, the probe head 33 will not miss any scans in the circumferential scanning process of the detected pipeline, ensuring a comprehensive scan of the detected pipeline.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
