This ultrasonic testing method has the advantages of easy operation, high detection sensitivity, and no damage to materials. Therefore, it is widely used in the quality inspection of GIS shell welds.

[0036] In this embodiment, by setting the annular seam ultrasonic walking detection mechanism 2, the entire detection device can be flexibly moved on the surface of the GLS shell while maintaining a stable detection position. The cooperation of the swing arm 25 and the GLS shell walking lubrication component 26 ensures that the ultrasonic detection device can adapt to the shell surface with different curvatures, thereby increasing the applicability and flexibility of the device; with the optimized design of the GLS shell walking lubrication component 26, not only lubrication is provided for the movement of the detection device, but also dust and impurities around the weld can be effectively collected, so that the lubricating oil can be evenly distributed on the walking path of the GLS shell 1, reducing friction and wear, and avoiding the waste of lubricating oil; the problem that the existing detection device usually affects the effect of the detector weld detection due to impurities on the pipeline surface and reduces the accuracy of data analysis is solved, and it can ensure that during the ultrasonic detection of the GLS shell weld, the area around the GLS shell weld can also be lubricated with oil to ensure efficient detection of the ultrasonic detection structure; it should be noted that the driving mode of the device can be manual or in conjunction with electric drive.

[0037] Embodiment 2, refer to the attached Figure 1-14On the basis of the first embodiment, in order to realize the limited walking of the GLS shell travel lubrication assembly 26, the surface weld of the GLS shell 1 is ultrasonically detected: the two ends of the horizontal truss 21 are respectively fixedly connected to the inner side of the end plate 22, and the inner wall of the horizontal truss 21 is provided with a mounting hole 210. The inner surface of the mounting hole 210 is penetrated and connected with a mounting rod 211. The two ends of the mounting rod 211 are fixedly connected with a U-shaped frame 212, and the lower end of the U-shaped frame 212 is fixedly connected with a lining plate 213. The U-shaped frame 212 and the lining plate 213 are both provided with two groups and are symmetrically distributed about the horizontal center axis of the horizontal truss 21. The lining plate The lower end of 213 is rotatably connected with an electromagnetic adsorption roller 214, and the electromagnetic adsorption roller 214 is movably connected with the outer surface of the GLS shell 1; the upper two ends of the vertical truss 23 are fixedly connected with a force ring plate 232, and a sleeve plate 231 is arranged at the center of the vertical truss 23, and the sleeve plate 231 and the vertical truss 23 are integrally formed, and the inner surface of the sleeve plate 231 is fixedly connected with the central outer wall of the horizontal truss 21, and T-shaped limit grooves 230 are respectively opened on the inner walls of both sides of the vertical truss 23, and a movable frame 233 is slidably installed on the inner surface of the T-shaped limit groove 230, and an ultrasonic detection probe 234 is detachably installed at the lower end of the movable frame 233;

[0038] In this embodiment, the two groups of end plates 22 are connected by a horizontal truss 21. The horizontal truss 21 serves as a support for the vertical truss 23 and is sleeved with a sleeve plate 231. The spacing between the two groups of horizontally relatively distributed movable frames 233 is adjusted according to the size of the weld of the GLS shell 1. The spacing of the ultrasonic detection probes 234 is adjusted synchronously. The operator holds the force-bearing ring plate 232 with both hands and pushes it. It should be noted that at this time, the annular seam ultrasonic walking detection mechanism 2 is adsorbed on the surface of the GLS shell 1 as a whole through the electromagnetic adsorption roller 214, and does not affect the annular seam movement of the device.

[0039] Embodiment 3, refer to the attached Figure 1-14 On the basis of the second embodiment, in order to make the GLS shell travel lubrication assembly 26 adapt to the shell surface with different curvatures: the fixed sleeve 24 is fixedly installed on the outer surfaces of both ends of the horizontal truss 21, one end of the swing arm 25 is fixedly connected with a pin shaft, the outer surface of the pin shaft is rotatably connected with the inner walls of both sides of the fixed sleeve 24, and the other end of the swing arm 25 is provided with a circular plate, and the circular plate and the swing arm 25 are an integrally formed "6"-shaped plate structure; a slide groove 250 is opened on the inner wall of the swing arm 25, and a sliding block 251 is slidably connected to the inner surface of the slide groove 250, and a curved abutment spring 252 is hinged on the outer side surface of the sliding block 251, and the other end of the curved abutment spring 252 is fixedly connected with a diagonal support plate 221, and the diagonal support plate 221 is fixedly installed on the end plate 22;

[0040] In this embodiment, one end of the swing arm 25 is connected to the fixed sleeve plate 24 fixedly mounted at both ends of the horizontal truss 21, and the other end is connected to the GLS shell walking lubrication component 26 for ultrasonic detection walking. When the GLS shell walking lubrication component 26 walks on the GLS shell 1, Figure 5 As shown, the swing arm 25 is affected by the GLS shell 1 of different sizes, and the two groups of swing arms 25 move relatively to the sides, and through the cooperation between the sliding block 251 and the curved abutment spring 252, the jitter of the GLS shell walking lubrication assembly 26 as a whole during walking can be reduced, further ensuring the accuracy of the ultrasonic detection probe 234 in ultrasonic detection of the weld and avoiding poor imaging effects.

[0041] Embodiment 4, refer to the attached Figure 1-14 On the basis of the third embodiment, in order to realize the auxiliary lubrication of the GLS shell 1 weld during ultrasonic testing and reduce the walking wear: the GLS shell walking lubrication assembly 26 includes a center roller 261, a rolling bearing 263, a hollow oil storage roller 264 and a shell walking wheel 266, the rolling bearing 263 is arranged on the inner side of the circular plate, the outer surface of the center roller 261 is fixedly connected with an arc-shaped weld touch plate 262, and the outer surface of the arc-shaped weld touch plate 262 is evenly provided with dust adsorption cotton plates 2621; the center roller 2 The two ends of the hollow oil storage roller 261 are fixedly connected with connecting columns 2611, the outer surface of the connecting column 2611 is fixedly connected with one end of the hollow oil storage roller 264, the outer surface of the hollow oil storage roller 264 is rotatably connected with the inner surface of the rolling bearing 263, and the end of the hollow oil storage roller 264 away from the connecting column 2611 is movably installed with an oil filling plug 2641; an oil storage cavity 2640 is opened on the central inner wall of the hollow oil storage roller 264, and a threaded groove 26400 is arranged on the inner wall of the oil storage cavity 2640. An oil guide hole 26401 is provided through the surface; an oil extension member is provided between the outer ring of the hollow oil storage roller 264 and the inner ring of the shell running wheel 266, and the oil extension member includes an inner sleeve ring plate 265. The outer surface of the hollow oil storage roller 264 is fixedly connected to the inner sleeve ring plate 265 and the central inner surface of the shell running wheel 266. An oil outlet hole 2650 is provided on the inner wall of the inner sleeve ring plate 265. The oil outlet hole 2650 is matched with the position of the oil guide hole 26401. An annular groove is provided on the inner wall of the outer ring of the shell running wheel 266. A strip-shaped oil diffusion hole 2660 is provided on the inner wall of the annular embedded groove, and a friction embedded ring 2661 is movably sleeved on the inner side surface of the annular embedded groove; the outer surface of the inner ring plate 265 is fixedly connected to a support auxiliary plate 2651, and six groups of the support auxiliary plates 2651 are arranged in a circular array about the central axis of the inner ring plate 265; the end of the support auxiliary plate 2651 away from the inner ring plate 265 is fixedly connected to an outer ring plate 2652, and the outer surface of the outer ring plate 2652 movably contacts the inner wall of the housing running wheel 266;

[0042] In this embodiment, if Figure 7-8As shown, a rolling bearing 263 is arranged at the connection between the hollow oil storage roller 264 and the swing arm 25 to ensure the lubrication of the hollow oil storage roller 264 when driving the shell running wheel 266 to roll. By opening the oil filling plug 2641 at one end of the hollow oil storage roller 264, lubricating oil is injected into the inner cavity of the oil storage chamber 2640. The oil storage chamber 2640 serves as a storage space for lubricating oil. During the overall rolling and rotation of the hollow oil storage roller 264 and the shell running wheel 266, the lubricating oil enters the interior of the threaded groove 26400, and under the action of rotation, the lubricating oil is discharged through the adapted multiple groups of oil guide holes 26401, and with the adaptation of the oil outlet holes 2650 opened on the surface of the inner ring plate 265, the lubricating oil enters the multiple groups of separation cavities between the inner ring plate 265 and the outer ring plate 2652. It should be said that It is obvious that the support cooperation plates 2651 are arranged in a circular array about the central axis of the inner ring plate 265. At this time, the support cooperation plates 2651 can serve as support members for guiding the rolling of the shell running wheels 266, and enhance the walking strength of the shell running wheels 266. In addition, the lubricating oil can be guided through the inclined surface of the support cooperation plates 2651 to facilitate better immersion in the outer ring plate 2652. In this way, when the shell running wheels 266 are in the process of continuous walking, the lubricating oil is evenly squeezed out from the strip-shaped oil diffusion holes 2660 and fills the friction embedded ring 2661, thereby achieving the effect of smearing lubricating oil while deforming, improving the smoothness of the overall ultrasonic detection of the annular seam ultrasonic walking detection mechanism 2, and enhancing the stability effect of the ultrasonic detection probe 234 during ultrasonic detection; and it is worth noting that, Figure 7 As shown, one end of the hollow oil storage roller 264 is connected to the connecting column 2611, and the connecting column 2611 here supports the center roller 261. When the shell walking wheel 266 walks on the surface of the GLS shell 1, the arc-shaped weld touch plate 262 is acted upon by elasticity to continuously clean the weld of the GLS shell 1. In this way, the weld can be cleaned before the ultrasonic detection probe 234 detects, thereby preventing factors such as impurities from affecting the accuracy of the ultrasonic detection data.

[0043] Embodiment 5, refer to the attached Figure 1-14 On the basis of the fourth embodiment, in order to avoid the waste of lubricating oil: a baffle 2631 is provided on the side of the rolling bearing 263 close to the center roller 261, and the central inner surface of the baffle 2631 is rotatably connected to the outer surface of the circular plate; oil collecting grooves 26501 are provided on the inner walls at both ends of the inner ring plate 265, and the oil collecting groove 26501 includes a wide mouth and a narrow mouth, and the wide mouth and the narrow mouth are an integrally formed hollow groove structure, and the oil collecting groove 26501 is adapted to penetrate a group of oil guide holes 26401, which are used to collect excess lubricating oil to avoid waste;

[0044] In this embodiment, if Figure 8 and Figure 13-14As shown, the width of the outer ring plate 2652 is narrower than the width of the inner ring plate 265 and the outer ring plate 2652. When the outer ring plate 2652 is soaked in oil, under the continuous squeezing action of the friction ring 2661 when the shell running wheel 266 rolls, part of the saturated oil in the outer ring plate 2652 is discharged through the strip oil diffusion hole 2660, and part of it will be extended through the outer ring plate 2652. At this time, the excess oil passes through the oil collecting groove 26501 and enters the oil storage chamber 2640 again. The special empty groove design of the oil collecting groove 26501 can facilitate better collection of oil, thus avoiding the waste of excess liquid.

[0045] The working principle and use process of the present invention are as follows: in actual use, first, by opening the oil filling plug 2641, the lubricating oil liquid for lubricating the surface of the GLS shell 1 is filled into the two groups of oil storage chambers 2640 respectively, and then the oil filling plug 2641 is used to seal the hollow oil storage roller 264. Subsequently, the ultrasonic detection probe 234 is connected to the ultrasonic detector through a connecting line, and the two are electrically connected. The annular seam ultrasonic walking detection mechanism 2 is adsorbed as a whole to the weld position on the surface of the GLS shell 1 through the electromagnetic adsorption roller 214. At this time, the two groups of ultrasonic detection probes 234 are adjusted. They are respectively located on both sides of the weld, so that the weld is in the center position; then, the operator holds the two groups of force-bearing ring plates 232 in his hands, and pushes the annular seam ultrasonic walking detection mechanism 2 to walk on the surface of the GLS shell 1 as a whole. At this time, the swing arm 25 is affected by the different sizes of the GLS shell 1, and the two groups of swing arms 25 move relatively to the sides, and through the mutual cooperation of the sliding block 251 and the curved abutment spring 252, the jitter of the GLS shell walking lubrication component 26 during the overall walking can be reduced, further ensuring the accuracy of the ultrasonic detection probe 234 to the weld ultrasonic detection; at this time, the shell The body running wheel 266 and the friction ring 2661 on its surface are in constant contact with the surface of the GLS housing 1. Due to the rotation, the lubricating oil in the inner cavity of the oil storage chamber 2640 is guided through the threaded groove 26400, and is discharged through the multiple sets of oil guide holes 26401 adapted to cooperate with the adaptation of the oil outlet holes 2650 provided on the surface of the inner ring plate 265. At this time, the lubricating oil enters the multiple sets of separation cavities between the inner ring plate 265 and the outer ring plate 2652. The lubricating oil is guided through the inclined surface of the supporting plate 2651, so as to better immerse in the outer ring plate 2652. In this way, when the housing running wheel 2 During continuous walking, the lubricating oil is evenly squeezed out from the strip oil-diffusing hole 2660 and fills the friction embedded ring 2661, thereby achieving the effect of smearing lubricating oil while deforming and walking, and improving the smoothness of the overall ultrasonic detection of the annular seam ultrasonic walking detection mechanism 2. At the same time, when the shell walking wheel 266 walks on the surface of the GLS shell 1, the arc-shaped weld touch plate 262 is affected by elasticity and continuously cleans the weld of the GLS shell 1. In this way, the weld can be cleaned before the ultrasonic detection probe 234 detects, avoiding factors such as impurities affecting the accuracy of the ultrasonic detection data.

[0046] 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.
