Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flaw detectors, in particular to an auxiliary device for ultrasonic flaw detectors. Background Art

[0002] An ultrasonic flaw detector is a non-destructive testing device that uses the characteristics of ultrasonic waves propagating in materials to detect internal defects, foreign objects, or structural changes in the materials. The probe is one of the core components of the ultrasonic flaw detector. It is responsible for emitting ultrasonic waves and receiving reflected signals. The propagation of ultrasonic waves is greatly affected by the contact situation between the probe and the object to be measured. The auxiliary device can provide a stable contact force and angle to ensure that ultrasonic waves can be accurately propagated and received, so as to obtain clear detection signals.

[0003] Traditional auxiliary devices for ultrasonic flaw detectors usually consist of components such as a clamping device, a scanning table, and a coupling medium. The clamping device is used to fix and support the probe to maintain a stable contact between the probe and the material to be measured. The clamping device usually includes components such as a clamping arm, a bracket, and an adjusting rod, which can be adjusted and fixed as needed. The scanning table is used to support the sample to be measured and provide a moving platform to control the movement of the probe on the surface of the sample. The coupling medium is used to transmit ultrasonic signals between the probe and the material to be measured, usually a liquid or a soft material.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figure 1 and Figure 2, An embodiment provided by the present utility model: An ultrasonic flaw detector auxiliary device includes an ultrasonic flaw detector body 1. Inside the ultrasonic flaw detector body 1, a connecting wire 2 is fixedly connected. On the outer wall of the connecting wire 2, a cylinder 3 is fixedly connected. The output end of the cylinder 3 is fixedly connected to a support plate 4. Inside the support plate 4, a rotating plate 5 is rotatably connected. On the upper surface of the cylinder 3, a support block 6 is fixedly connected. Inside the support block 6, a rotating block 7 is rotatably connected. The rotating plate 5 is rotatably connected inside the rotating block 7. On the side wall of the rotating block 7, a hollow column 8 is fixedly connected. The inner wall of the hollow column 8 fits with the outer wall of the connecting wire 2. On the upper surface of the ultrasonic flaw detector body 1, a probe 9 is provided. The outer wall of the probe 9 fits with the inside of the hollow column 8. The probe 9 fits with one end of the connecting wire 2. On the upper surface of the ultrasonic flaw detector body 1, a support assembly is provided;

[0024] Specifically, first, the output end of the cylinder 3 will start, generating a powerful driving force. This driving force, through precise mechanical transmission, pulls the support plate 4 to move smoothly. The movement of the support plate 4 is not isolated. It will have a linkage effect with the rotating plate 5. When the support plate 4 moves, it will drive the rotating plate 5 to rotate accordingly. The rotation of the rotating plate 5 is not aimless but is part of a carefully designed mechanical chain reaction. Its rotation will cause the rotating block 7 to rotate inside the support block 6. This rotation process is very crucial because it directly relates to the rotation of the hollow column 8. The hollow column 8 plays a key role in this system. Its rotation means that the connection between the probe 9 originally clamped on the hollow column 8 and the connecting wire 2 will be released. When the hollow column 8 rotates to an appropriate position and the clamping relationship is broken, the probe 9 can be easily replaced. The staff can quickly and accurately replace the probe 9 suitable for the current detection task according to actual needs. This not only greatly improves work efficiency but also ensures the continuity and accuracy of the detection work.

[0025] Referring to Figure 1 and Figure 3 , the support assembly includes a connecting plate 10. The connecting plate 10 is fixedly connected to the upper surface of the ultrasonic flaw detector body 1. A sliding block 11 is slidably connected to the side wall of the connecting plate 10. Inside the sliding block 11, a sphere one 12 is rotatably connected. Inside the sphere one 12, a connecting column 18 is fixedly connected;

[0026] Specifically, the connecting plate 10 plays a basic role in connection and support. There is a sliding block 11 on the side wall of the connecting plate 10. This sliding connection enables the sliding block 11 to slide freely on the connecting plate 10. Inside the sliding block 11, there is a first sphere 12 rotatably connected. This rotational connection allows the first sphere 12 to rotate freely inside the sliding block 11. Inside the first sphere 12, there is a connecting column 18 fixedly connected. As an important part of the support assembly, the connecting column 18 ensures the stability and reliability of the flaw detector during use. At the same time, the connecting column 18 also takes into account the convenience of carrying the flaw detector, making it more convenient during transportation and storage.

[0027] Refer to Figure 1 and Figure 3 , a motor 13 is fixedly connected to the lower surface of the ultrasonic flaw detector body 1. The output end of the motor 13 is fixedly connected to a connecting block 14. A first universal wheel 15 is fixedly connected to the lower surface of the connecting block 14. An inclined surface block 16 is fixedly connected to the side wall of the connecting block 14. One end of the connecting column 18 is fixedly connected to a second sphere 17. The second sphere 17 is rotatably connected inside the inclined surface block 16. A fixing plate 19 is fixedly connected to the side wall of the connecting block 14. A fixing block 20 is rotatably connected inside the ultrasonic flaw detector body 1. The fixing plate 19 is fixedly connected to the side wall of the fixing block 20. A second universal wheel 21 is fixedly connected to the lower surface of the fixing block 20;

[0028] Specifically, when the motor 13 is started, its output end will drive the connecting block 14 to rotate. This rotational movement not only directly drives the rotation of the first universal wheel 15, but also further drives the rotation of the inclined surface block 16 as the connecting block 14 rotates. The ingenious part of the inclined surface block 16 is that the second sphere 17 is embedded inside it. When the inclined surface block 16 rotates, the second sphere 17 will roll inside it. This rolling not only reduces friction and improves the smoothness of rotation, but also drives the rotation of the first sphere 12 inside the sliding block 11 through the connecting column 18. This series of rotational and rolling movements together constitute an important part of the moving mechanism of the ultrasonic flaw detector. At the same time, the rotation of the connecting block 14 will also drive the rotation of the fixing plate 19. The fixing plate 19 is equipped with the fixing block 20. When the fixing plate 19 rotates, the fixing block 20 will also rotate accordingly. The rotation of the fixing block 20 directly drives the rotation of the second universal wheel 21. The presence of the second universal wheel 21 not only enhances the stability of the flaw detector during movement, but also enables it to move more flexibly on different terrains and in different environments. This mechanism not only ensures the stability and smoothness of the flaw detector during movement, but also greatly improves its ability to adapt to different environments. In actual use, the operator only needs to simply push the flaw detector to easily achieve its movement, thus making various detection tasks more convenient.

[0029] Working principle: When the staff needs to replace different probes 9, first, pull the support plate 4 to move through the output end of the cylinder 3. The movement of the support plate 4 will drive the rotating plate 5 to rotate. The rotation of the rotating plate 5 will drive the rotating block 7 to rotate inside the support block 6. The rotation of the rotating block 7 will drive the hollow column 8 to rotate. At this time, the hollow column 8 is no longer in the position where it engages the probe 9 and the connecting wire 2, and then different probes 9 can be replaced. When it is necessary to move the ultrasonic flaw detector body 1, first, drive the connecting block 14 to rotate through the output end of the motor 13. The rotation of the connecting block 14 will drive the first universal wheel 15 to rotate. The rotation of the connecting block 14 will also drive the inclined block 16 to rotate. The rotation of the inclined block 16 will drive the second sphere 17 to rotate inside it. The rotation of the second sphere 17 will cause the connecting column 18 to drive the first sphere 12 to rotate inside the sliding block 11. The rotation of the connecting column 18 will cause the first sphere 12 to drive the sliding block 11 to slide on the side wall of the connecting plate 10. At the same time, the rotation of the connecting block 14 will drive the fixing plate 19 to rotate. The rotation of the fixing plate 19 will drive the fixing block 20 to rotate. The rotation of the fixing block 20 will drive the second universal wheel 21 to rotate. Then, the ultrasonic flaw detector body 1 can be pushed to make it move.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
