DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] The embodiment of the present application provides a weld inspection tool, which can solve the problem in the related art that the existing high-frequency welded pipe weld inspection does not undergo inner wall cleaning, resulting in inaccurate inspection results.

[0035] See also Figures 1 to 10 The embodiment of the present application provides a weld inspection tool, which includes: a base frame 1, an adjustment component, a first cleaning component and a detection probe 16, wherein the base frame 1 is provided with a first vertical seat 2 and a second vertical seat 3 on opposite sides, the first vertical seat 2 is provided with an abutment 9, and the second vertical seat 3 is provided with a sealing member 8 opposite to the abutment 9, and the abutment 9 and the sealing member 8 are used to install the welding pipe, and a through hole 91 is opened in the middle of the abutment 9; the adjustment component is arranged on the first vertical seat 2, the adjustment component includes a second telescopic cylinder 12, and the output end of the second telescopic cylinder 12 is penetrated by the through hole 91 and extends to one side of the sealing member 8; the first cleaning component is connected to the output end of the second telescopic cylinder 12, the first cleaning component includes a cleaning head 20 and a second shell 15, and the cleaning head 20 is arranged around the surface of the second shell 15; the detection probe 16 is arranged on the side of the second shell 15 away from the adjustment component.

[0036] In the present application, a second telescopic cylinder 12 is provided to enable the cleaning head 20 and the detection probe 16 to move. While the detection probe 16 detects weld defects in the welded pipe, the cleaning head 20 moves to clean impurities in the welded pipe, thereby reducing interference factors and ensuring accurate transmission of the detection signal.

[0037] Among them, the detection probe 16 of the present application is an ultrasonic probe. Ultrasonic detection is a non-destructive testing technology that uses high-frequency sound waves to detect internal defects of materials. Ultrasonic waves have penetrating and reflective properties and can detect and locate defects in steel pipes. The ultrasonic probe transmits and receives ultrasonic signals and calculates the transmission time, intensity, echo amplitude and other parameters of the sound waves in the detection link to determine whether there are defects and determine their location, nature and size.

[0038] A first telescopic cylinder 7 is installed on the second vertical seat 3, and a control indicator light 33 connected to the detection probe 16 is installed on the first vertical seat 2. When the tool is used, the welded pipe to be detected is inserted into the abutment 9, and then the first telescopic cylinder 7 is started to make the sealing member 8 abut against the other end of the welded pipe, and the cleaning head 20 and the ultrasonic detection probe 16 are driven to move by the second telescopic cylinder 12. The cleaning head 20 moves to clean up the impurities in the welded pipe, reduce interference factors, and ensure that the ultrasonic signal can be accurately transmitted. Then, the scanned data is compared with the acceptance limit. If the signal is lower than the acceptance limit, the indicator light is green, indicating that the weld is qualified; if the signal is higher than the acceptance limit, the indicator light is red, indicating that the welding of the welded pipe is unqualified.

[0039] Furthermore, in order to enable the cleaning head 20 to better adapt to the welded pipe, improve the cleaning of the welded pipe, and facilitate the propagation of the ultrasonic signal, thereby improving the detection efficiency, based on the above embodiment, in this embodiment, the first cleaning component also includes an adjustment member arranged inside the second shell 15 and used to adjust the cleaning head 20, and the adjustment member is used to drive the cleaning head 20 close to or away from the second shell 15.

[0040] In this embodiment, the adjustment member can control the cleaning head 20 to shrink or expand. The number of cleaning heads 20 is four, and the four cleaning heads 20 form a quarter circle and are equidistantly arranged around the second shell 15 .

[0041] Specifically, the adjusting member includes: a toothed disc 24, a second motor 28, a transmission gear 29, a sliding shaft 26 and a connecting rod 25. The toothed disc 24 is rotatably connected to the inside of the second shell 15, and the toothed disc 24 is provided with arc-shaped adjustment grooves 27 having the same number as the cleaning head 20; the second motor 28 is installed inside the second shell 15; the transmission gear 29 is fixed on the output shaft of the second motor 28 and meshes with the toothed disc 24; the sliding shaft 26 is slidably connected to the inside of the arc-shaped adjustment groove 27; one end of the connecting rod 25 is connected to the sliding shaft 26, and the other end passes through the surface of the second shell 15 and is fixed to the cleaning head 20, and the connecting rod 25 is slidably connected to the second shell 15.

[0042] See also Figures 8 to 10As shown, an adjusting member for adjusting the cleaning head 20 is installed inside the second shell 15, a second motor 28 is installed in the second shell 15, and a transmission gear 29 is fixed on the output shaft of the second motor 28. At the same time, a toothed disc 24 is arranged in the second shell 15, and the toothed disc 24 is arranged in the middle of the second shell 15, and the toothed disc 24 is meshed with the transmission gear 29. When the second motor 28 is working, the toothed disc 24 is driven to rotate through the transmission gear 29.

[0043] In order to realize the contraction or expansion of the cleaning head 20 when the toothed disc 24 rotates, an arc-shaped adjustment groove 27 is provided on the toothed disc 24. In this embodiment, four cleaning heads 20 are provided, and four arc-shaped adjustment grooves 27 need to be provided, wherein one end of the arc-shaped adjustment groove 27 is close to the middle of the toothed disc 24, and the other end is close to the edge of the toothed disc 24. A sliding shaft 26 is provided in the arc-shaped adjustment groove 27, and the sliding shaft 26 can slide smoothly in the arc-shaped adjustment groove 27. A connecting rod 25 is fixedly connected between the sliding shaft 26 and the cleaning head 20, and the connecting rod 25 is passed through the surface of the second housing 15. When the toothed disc 24 rotates in a set direction and a set angle, the sliding shaft 26 can slide smoothly in the arc-shaped adjustment groove 27, so that the sliding shaft 26 drives the connecting rod 25 to move along the radial direction of the toothed disc 24, thereby driving the cleaning head 20 to contract or expand.

[0044] On the basis of the above embodiment, in this embodiment, a telescopic hole 30 is opened on the outer periphery of the second shell 15, and the other end of the connecting rod 25 passes through the telescopic hole 30 and extends to the outside of the second shell 15; a slider 31 is fixedly connected to the inner wall of the telescopic hole 30, and a limiting groove 32 slidably connected to the slider 31 is opened on the surface of the connecting rod 25.

[0045] In order to ensure that the connecting rod 25 can smoothly pass through the surface of the second housing 15 and slide with the second housing 15, a telescopic hole 30 is opened on the surface of the second housing 15, and the position of the telescopic hole 30 corresponds to the position of the cleaning head 20. A slider 31 for limiting the connecting rod 25 is installed on the inner side of the telescopic hole 30, and a limiting groove 32 adapted to the slider 31 is opened inside the connecting rod 25. When the connecting rod 25 moves telescopically, the connecting rod 25 is limited by the slider 31. A sealing ring that abuts against the outer wall of the connecting rod 25 can also be installed on the outside of the telescopic hole 30 to improve the sealing inside the second housing 15.

[0046] Therefore, the toothed disc 24 is driven to rotate through the transmission cooperation between the second motor 28 and the transmission gear 29. The rotation of the toothed disc 24 causes the cleaning head 20 to contract or expand through the sliding cooperation of the sliding shaft 26 in the arc-shaped adjustment groove 27, so that the cleaning head 20 can better adapt to the welded pipe, and avoid the cleaning head 20 from being unable to contact the inner wall of the welded pipe after wear, which is helpful for the propagation of ultrasonic signals and thus improves the detection efficiency.

[0047] On the basis of the above embodiments, in this embodiment, in order to further improve the cleaning effect, the weld inspection tooling also includes: a second cleaning component, the second cleaning component is arranged on the second vertical seat 3, the second cleaning component includes a water pipe 10, and one end of the water pipe 10 is connected to the inside of the seal 8.

[0048] In this embodiment, the first telescopic cylinder 7 is penetrated by the second vertical seat 3, and the output shaft of the first telescopic cylinder 7 is connected to the mounting frame 6, and the sealing member 8 is arranged on the mounting frame 6. That is to say, the sealing member 8 is fixed on the mounting frame 6, and the water pipe 10 is also arranged on the mounting frame 6, and the external water source can be transported from the sealing member 8 to the welded pipe through the water pipe 10 to flush the inside of the welded pipe. Among them, the water pipe 10 is connected to a connecting pipe 11 that is connected to the inside of the sealing member 8, and a water inlet valve is installed at one end of the water pipe 10, and a pressure gauge is installed on the water inlet valve.

[0049] Furthermore, in order to collect water, a collection trough 4 is provided inside the base frame 1, and a filter plate 5 is embedded inside the collection trough 4. A drainage pipe connected to the collection trough 4 is fixedly connected to the side wall of the base frame 1. The collection trough 4 collects the water after detection and filters it through the filter plate 5, so that the detection water can be reused.

[0050] In order to improve the detection accuracy of high-frequency welded pipes, based on the above embodiments, in this embodiment, the adjustment component is further provided with: a first shell 13, a connecting pipe 14 and a driving structure, wherein the first shell 13 is arranged at one end of the output shaft of the second telescopic cylinder 12; the connecting pipe 14 is arranged between the first shell 13 and the second shell 15; the driving structure is arranged on the first shell 13 and is connected to the connecting pipe 14.

[0051] See also Figures 2 to 6 As shown, the output shaft of the second telescopic cylinder 12 passes through the through hole 91 on the abutment 9 and is connected to the first shell 13. A driving structure is fixed to the end of the first shell 13 away from the second telescopic cylinder 12, and a connecting pipe 14 is fixed to the end of the driving structure away from the second telescopic cylinder 12, and the connecting pipe 14 is fixed to the second shell 15.

[0052] Therefore, when the welded pipe is installed, the second shell 15, the connecting pipe 14 and the first shell 13 can all extend into the interior of the welded pipe; the output end of the second telescopic cylinder 12 penetrates through the interior of the abutment 9 through the perforation 91, thereby pushing the cleaning head 20 and the ultrasonic detection probe 16, and the cleaning head 20 moves to clean impurities in the steel pipe, reducing interference factors and ensuring accurate propagation of ultrasonic signals.

[0053] The driving structure includes: a bearing 21, a ring gear 18, a first motor 17 and a rotating gear 19, wherein the bearing 21 is fixed to the first shell 13 on the side close to the second shell 15; the ring gear 18 is fixedly connected to the inner ring of the bearing 21, and one end of the ring gear 18 is connected to the connecting pipe 14; the first motor 17 is fixed inside the first shell 13; the rotating gear 19 is fixedly connected to the output shaft of the first motor 17 and meshes with the ring gear 18.

[0054] Therefore, when the first motor 17 is working, it can drive the rotating gear 19 to rotate, and then drive the ring gear 18 and the inner ring of the bearing 21 to rotate. Since the connecting tube 14 is fixed to the ring gear 18, the ring gear 18 can drive the connecting tube 14, the second shell 15, the cleaning head 20 and the detection probe 16 to rotate. In order to achieve the sealing of the first shell 13, in this embodiment, a sealing plate 22 is installed inside the first shell 13 by bolts, and a through hole is opened in the sealing plate 22. The output shaft of the first motor 17 extends to the outside of the first shell 13 through the through hole. The through hole and the through hole 91 are both installed with a sealing gasket 23 to prevent water leakage.

[0055] It should be noted that in the present application, the ultrasonic detection probe 16 is a waterproof ultrasonic detection probe 16, and the first motor 17 and the second motor 28 are both waterproof motors. Battery modules are installed in the first shell 13 and the second shell 15, and a waterproof shell is installed on the outside of the battery module. The ultrasonic detection probe 16 is a conventional device known to the public in the prior art, so its specific structural composition and working principle will not be described in detail in this article. The specification range of the welded pipe is high-frequency welded steel pipe, and the specifications of the high-frequency welded steel pipe are: outer diameter Φ219 mm ~ Φ610 mm, wall thickness 6 mm ~ 18 mm.

[0056] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

[0057] In summary, the high-frequency welded pipe weld inspection tool with indication operation detects steel pipe weld defects by moving the cleaning head 20 and the ultrasonic probe. The cleaning head 20 moves to clean impurities in the pipe, reduces interference factors, and ensures accurate propagation and reflection of ultrasonic signals, thereby creating a good working environment for detection work. The high-frequency welded pipe weld inspection tool with indication operation drives the toothed disc 24 to rotate through the transmission cooperation of the second motor 28 and the transmission gear 29. The rotation of the toothed disc 24 causes the cleaning head 20 to contract or expand through the sliding cooperation of the sliding shaft 26 in the arc-shaped adjustment groove 27, so that the cleaning head 20 can better adapt to the steel pipe, improve the cleaning of the steel pipe, and help the propagation of ultrasonic signals, thereby improving the detection efficiency, achieving the advantages of convenient operation and high detection quality, and effectively solving the problem of low detection accuracy.
