Industrial X-ray flaw detector is a general term for equipment that performs X-ray photography or tomography on the internal structure of an object, including X-ray tube head assembly, control box and connecting cables. X-ray flaw detectors can be divided into directional and circumferential types according to the direction of X-ray emission and window range; they can be divided into fixed and mobile types according to the installation form.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-7 , the present invention provides a technical solution:

[0035] Embodiment 1:

[0036] An X-ray machine mobile tooling, comprising a first track 1 and a second track 2, two groups of round tube flaw detection racks 7 and four groups of square tube flaw detection racks 16 are arranged between the first track 1 and the second track 2, and the spacing between the two groups of round tube flaw detection racks 7 and the square tube flaw detection racks 16 can be adjusted;

[0037] In this embodiment, a round tube flaw detection frame 7 and a square tube flaw detection frame 16 are respectively arranged in the X-ray machine, so that round tubes and square tubes can be flaw detected. It is a non-destructive flaw detection method that uses the characteristics of X-rays penetrating materials and attenuating in materials to find defects therein. X-rays can detect internal defects of metal and non-metal materials and their products, such as volume defects such as pores, slag inclusions, and incomplete penetration in welds.

[0038] It should be noted that, during specific use, two groups of round tube flaw detection frames 7 are respectively arranged on both sides of the round tube. Since the spacing between the two groups of round tube flaw detection frames 7 can be adjusted, round tubes of different diameters can be adapted. Similarly, the spacing between the square tube flaw detection frames 16 can be adjusted, so that the structure of this embodiment can adapt to square tubes of different sizes, thereby increasing the flaw detection application range of the entire X-ray machine.

[0039] Fixed support seats 3 are fixedly installed in the first track 1 and the second track 2, and a ball screw 6 is rotatably connected between the two sets of fixed support seats 3. A movable seat 15 is detachably provided on the surface of the ball screw 6. The round tube flaw detection frame 7 and the square tube flaw detection frame 16 are both moved on the ball screw 6 through the movable seat 15, and one end of the ball screw 6 is transmission-connected to a motor 38.

[0040] In this embodiment, the round tube flaw detection frame 7 and the square tube flaw detection frame 16 are both detachably connected to the ball screw 6. Because, when flaw detection is performed on a round tube or a square tube, the round tube flaw detection frame 7 or the square tube flaw detection frame 16 can be selected to be installed. During flaw detection, the first X-ray probe 13 and the second X-ray probe 17 are attached to the outer wall of the round tube or the square tube, thereby completing the overall flaw detection of the round tube or the square tube.

[0041] An active movable support seat 4 is slidably installed in the first track 1 on the side away from the fixed support seat 3, and an adjustment plate 36 is fixedly installed on one side of the first track 1. A transverse adjustment rod 35 is threadedly connected to the adjustment plate 36. One end of the transverse adjustment rod 35 is rotatably installed in the active movable support seat 4. A passive movable support seat 5 is slidably installed in the second track 2, and a ball screw 6 is also rotatably installed between the active movable support seat 4 and the passive movable support seat 5.

[0042] In this embodiment, when flaw detection is performed on a round tube, the thread of the transverse adjustment rod 35 is threadedly connected to the threaded plate in the adjustment plate 36 by rotating the transverse adjustment rod 35, and at the same time, one end of the transverse adjustment rod 35 is rotatably connected to the active movable support seat 4. Therefore, the rotation of the transverse adjustment rod 35 can drive the active movable support seat 4 to slide in the first track 1. At the same time, since the ball screw 6 is connected between the active movable support seat 4 and the passive movable support seat 5, the passive movable support seat 5 can move synchronously with the movement of the active movable support seat 4 in the second track 2. Therefore, the round tube flaw detection frame 7 on one side can be brought closer to the round tube flaw detection frame 7 on the other side, so that the two groups of round tube flaw detection frames 7 wrap and clamp the round tube, so that the first X-ray probe 13 fits against the wall of the round tube for flaw detection.

[0043] Grooves 37 are symmetrically provided below the passive movable support seat 5 , and groove wheels 39 are rotatably installed in the grooves 37 . Bosses are symmetrically provided on both sides of the second track 2 , and the groove wheels 39 and the bosses are matched.

[0044] It should be noted that when the passive movable support seat 5 follows the movement, in order to reduce the resistance caused by the friction between the passive movable support seat 5 and the second track 2, grooves 37 are opened on both sides of the bottom of the passive movable support seat 5, and groove wheels 39 are arranged in the grooves 37. The groove wheels 39 are slidably mounted on the bosses on both sides of the second track 2 to ensure the stability of the moving structure of the ball screw 6 between the active movable support seat 4 and the passive movable support seat 5, thereby realizing the spacing adjustment between the round tube flaw detection frame 7 and the square tube flaw detection frame 16.

[0045] Specifically, the two groups of round tube flaw detection frames 7 are symmetrically arranged, and a first X-ray probe 13 is arranged at a central position in the round tube flaw detection frame 7, an elastically connected support plate 10 is arranged at a central position of the inner circle of the round tube flaw detection frame 7, one side of the support plate 10 is connected to a mounting plate 11 through a spring rod 14, the first X-ray probe 13 is fixedly installed on one side of the mounting plate 11, and a universal ball touch rod 12 is connected to the top of the spring rod 14. When the first X-ray probe 13 is in use, the universal ball touch rod 12 and the fixed support seat 3 are both arranged to fit the outer wall of the pipeline to be inspected.

[0046] It should be noted that in order to ensure the stability of the first X-ray probe 13, two sets of universal ball touch rods 12 are symmetrically arranged on both sides of the first X-ray probe 13. When the universal ball touch rods 12 and the first X-ray probe 13 are in contact with the outer wall of the circular tube, the first X-ray probe 13 is started to perform pipeline flaw detection.

[0047] Among them, the first X-ray probe 13 and the universal ball touch rod 12 are connected to the round tube flaw detection frame 7 through the support plate 10. At the same time, a universal connection structure is arranged between the support plate 10 and the round tube flaw detection frame 7 to ensure the detection position of the first X-ray probe 13 and the emission direction of the X-ray, thereby ensuring the flaw detection range of the X-ray machine.

[0048] In this embodiment, four groups of square tube flaw detection frames 16 are symmetrically arranged in pairs in the horizontal direction and the vertical direction. During detection, they are arranged at the four corners of the square tube. The square tube flaw detection frame 16 includes a horizontal support plate 29 and a vertical support plate 40. An inclined plate is connected between the horizontal support plate 29 and the vertical support plate 40, and a second X-ray probe 17 is arranged in the inclined plate.

[0049] It should be noted that the connection position between the second X-ray probe 17 and the inclined plate is also provided with a universal connection structure to ensure the detection position of the second X-ray probe 17 and the emission direction of the X-rays, thereby ensuring the flaw detection range of the X-ray machine.

[0050] It should be noted that the connection positions of the round tube flaw detection frame 7 and the square tube flaw detection frame 16 and the ball screw 6 can be provided with a universal connection structure, so that the first X-ray probe 13 and the second X-ray probe 17 can contact any position on the surface of the pipeline, thereby increasing the flaw detection area of ​​the X-ray machine.

[0051] The inner ring of the round tube flaw detection frame 7 has a plurality of groups of symmetrically arranged ear plates 9 in an equidistant array, and a supporting wheel 8 is rotatably installed between two adjacent groups of ear plates 9. The supporting wheel 8 is configured as a rubber wheel structure. Balancing rollers 18 are provided on the inner sides of the horizontal support plates 29 and the vertical support plates 40, and the balancing rollers 18 are also configured as rubber wheel structures.

[0052] In this embodiment, a supporting wheel 8 and a balancing roller 18 are respectively provided in the round tube flaw detection frame 7 and the square tube flaw detection frame 16, and the supporting wheel 8 and the balancing roller 18 are both arranged in a rubber wheel structure, which can not only ensure the structural stability of the round tube flaw detection frame 7 and the square tube flaw detection frame 16 when they are deployed for inspection, but also effectively reduce the wear and scratches caused by the supporting wheel 8 and the balancing roller 18 to the pipe to be inspected.

[0053] A telescopic adjustment component is arranged between the two horizontal support plates 29, and a lifting adjustment component is arranged between the two vertical support plates 40. The telescopic adjustment component includes a horizontal adjustment sleeve 20 and a horizontal adjustment rod 19 slidably connected to the horizontal adjustment sleeve 20. The horizontal adjustment rod 19 is located inside the horizontal adjustment sleeve 20 and is rotatably connected to a screw 21 at one end. A bevel gear 22 is connected to one end of the screw 21. An adjustment rod 23 is rotatably installed on the outer wall of the horizontal adjustment sleeve 20. The adjustment rod 23 is located in the horizontal adjustment sleeve 20 and is also fixedly connected to the bevel gear 22 at one end. The two sets of bevel gears 22 are meshed, and one end of the screw 21 connected to the bevel gear 22 is rotatably connected to the horizontal adjustment sleeve 20 through a connecting shaft 24. Guide strips 41 are symmetrically arranged on both sides of the horizontal adjustment rod 19, and a guide groove matching the guide strip 41 is opened in the horizontal adjustment sleeve 20.

[0054] In this embodiment, before the square tube is subjected to flaw detection, the threaded adjustment structure of the transverse adjustment rod 35 is not used. The telescopic adjustment assembly can not only ensure the connection stability between the two groups of square tube flaw detection frames 16, but also quickly adapt to square tubes of different sizes. Specifically, the adjustment rod 23 is rotated to drive the bevel gear 22 in the horizontal adjustment sleeve 20. The two groups of bevel gears 22 are meshed, thereby driving the screw rod 21 to rotate. The screw rod 21 is threadedly connected to the horizontal adjustment rod 19. Since the horizontal adjustment rod 19 is limited by the guide bar 41, the rotation of the thread can start the horizontal adjustment rod 19 to move along the guide bar 41 in the horizontal adjustment sleeve 20, thereby completing the length adjustment of the telescopic adjustment assembly.

[0055] The lifting and adjusting assembly includes a supporting square tube 26 and a lifting rod 25 slidably connected to the supporting square tube 26. A gear 28 is rotatably connected to the supporting square tube 26. The lifting rod 25 is located in the supporting square tube 26 and one end is fixedly connected to a rack 27. The gear 28 and the rack 27 are meshed. A rotating rod 42 with a damping bearing is arranged in the gear 28, and the rotating rod 42 extends to the outside of the supporting square tube 26.

[0056] At the same time, in this embodiment, the spacing between the square tube flaw detection frames 16 in the vertical direction can also be adjusted according to the cross-sectional width of the square tube through the lifting and adjusting assembly. Specifically, the rotating rod 42 is rotated to drive the gear 28 located at one end inside the supporting square tube 26 to rotate, and the gear 28 and the rack 27 are engaged. Therefore, the gear 28 can drive the rack 27 to slide in the supporting square tube 26, thereby pushing the lifting rod 25 to move in the supporting square tube 26, thereby completing the adjustment in the vertical direction, thereby adjusting according to the cross-sectional length and width of the square tube, and increasing the applicable range of the X-ray machine.

[0057] Embodiment 2:

[0058] Based on the first embodiment, when flaw detection is performed on the opposite tube, since the square tube flaw detection rack 16 is provided in four groups, corresponding to the four corners of the square tube, respectively, in order to ensure the fitting arrangement of the balancing roller 18 and the tube, and to ensure the flaw detection accuracy of the second X-ray probe 17 on the opposite tube, the following structure is provided in this embodiment:

[0059] A first spring 30 is arranged on the outer side of the inclined plate, the second X-ray probe 17 is elastically connected to the first spring 30, the balancing roller 18 is rotatably connected to the square tube flaw detection frame 16 through a double-ear bracket 33, one side of the double-ear bracket 33 is fixedly connected to an elastic connecting rod 34, the elastic connecting rod 34 respectively penetrates the horizontal support plate 29 and the vertical support plate 40, and one end of the elastic connecting rod 34 is fixedly connected to the limit plate 32, and a second spring 31 is arranged between the limit plate 32 and the horizontal support plate 29 and the vertical support plate 40.

[0060] In this embodiment, the second X-ray probe 17 is elastically connected by the first spring 30, and the balancing roller 18 is elastically connected by the second spring 31. The first spring 30 and the second spring 31 are used to completely fit the second X-ray probe 17 and the balancing roller 18 to the square tube to be detected, thereby ensuring the stability of the structure and the accuracy of X-ray emission detection.

[0061] Working principle: This device is respectively provided with a round tube flaw detection frame 7 and a square tube flaw detection frame 16 in the X-ray machine, which can perform flaw detection on round tubes and square tubes. It is a non-destructive flaw detection method that uses the characteristics of X-rays penetrating materials and attenuating in materials to find defects therein. X-rays can check the internal defects of metal and non-metal materials and their products, such as volume defects such as pores in welds, slag inclusions, and incomplete penetration.

[0062] When this device is used to detect flaws in round tubes:

[0063] By rotating the transverse adjustment rod 35, the thread of the transverse adjustment rod 35 and the threaded plate in the adjustment plate 36 are threadedly connected, and at the same time, one end of the transverse adjustment rod 35 is rotatably connected to the active movable support seat 4, so the rotation of the transverse adjustment rod 35 can drive the active movable support seat 4 to slide in the first track 1. At the same time, since the ball screw 6 is connected between the active movable support seat 4 and the passive movable support seat 5, the passive movable support seat 5 can move synchronously with the movement of the active movable support seat 4 in the second track 2, so that the round tube flaw detection frame 7 on one side can be brought closer to the round tube flaw detection frame 7 on the other side, so that the two groups of round tube flaw detection frames 7 can wrap and clamp the round tube, so that the first X-ray probe 13 and the round tube wall are fitted for flaw detection;

[0064] When this device is used to detect flaws in the opposite tube:

[0065] Without using the threaded adjustment structure of the transverse adjustment rod 35, the telescopic adjustment assembly can not only ensure the connection stability between the two sets of square tube flaw detection frames 16, but also quickly adapt to square tubes of different sizes. Specifically, the adjustment rod 23 is rotated to drive the bevel gear 22 in the horizontal adjustment sleeve 20, and the two sets of bevel gears 22 are meshed, thereby driving the screw rod 21 to rotate. The screw rod 21 and the horizontal adjustment rod 19 are threadedly connected. Since the horizontal adjustment rod 19 is limited by the guide strip 41, the rotation of the thread can start the horizontal adjustment rod 19 to move along the guide strip 41 in the horizontal adjustment sleeve 20, thereby completing the length adjustment of the telescopic adjustment assembly.

[0066] Rotating the rotating rod 42 drives the gear 28 located at one end inside the supporting square tube 26 to rotate, and the gear 28 and the rack 27 are meshed. Therefore, the gear 28 can drive the rack 27 to slide inside the supporting square tube 26, thereby pushing the lifting rod 25 to move inside the supporting square tube 26, thereby completing the adjustment in the vertical direction, and adjusting according to the cross-sectional length and width of the square tube, thereby increasing the application range of the X-ray machine.

[0067] The second X-ray probe 17 is started to perform flaw detection on the corners of the square tube.

[0068] It should be noted that the motor 38 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
