Abstract
Description
Technical Field
[0001] This utility model belongs to the field of detection technology, specifically relating to an ultrasonic probe auxiliary moving device. Background Technology
[0002] Ultrasonic testing is a non-destructive testing technique widely used in various fields such as medical, industrial, automotive, and aerospace. Various welds in industrial power plant boilers require ultrasonic testing to detect internal defects, such as circumferential welds of cylinders, fillet welds of pipes, and butt welds of flat plates. When using traditional A-mode pulse-echo ultrasonic testing, the existing solution involves moving the probe in a zigzag pattern on the inspection surface. The probe's back-and-forth movement must ensure that the entire weld joint volume is scanned, and the probe must remain perpendicular to the weld during movement. The problem with this existing technology is that maintaining the probe's perpendicularity to the weld at all times requires highly skilled and experienced operators to ensure accurate probe movement. Inexperienced operators are prone to misaligning the probe with the weld, significantly increasing the risk of missed defects. Furthermore, this method greatly reduces testing efficiency and increases the workload of the operators. Utility Model Content

[0023] Example
[0024] Please refer to Figure 1-4This embodiment provides an auxiliary moving device for an ultrasonic probe, which includes a telescopic rod 1 and a pair of flexible wheel frames 2. It is suitable for a type A pulse-echo ultrasonic probe 3. Two telescopic rods 1 are provided and installed between the two flexible wheel frames 2. The ultrasonic probe 3 is placed between the two telescopic rods 1, and the ultrasonic probe 3 can slide along the telescopic rods 1. It should be noted that, to ensure stable sliding of the ultrasonic probe 3 between the two telescopic rods 1, sliding blocks can be installed on both sides of the ultrasonic probe 3. The sliding blocks are L-shaped, with their vertical sides fixed to the ultrasonic probe 3 and their horizontal sides connected to the telescopic rods 1. The telescopic rod 1 contacts the sliding mechanism. Specifically, the telescopic rod 1 includes a first rod 11 and a second rod 12. The diameter of the first rod 11 is smaller than that of the second rod 12. One end of the first rod 11 is inserted into the second rod 12, and a nut is welded to the end of the second rod 12. A fastening bolt is threadedly connected to the nut. When the length of the telescopic rod 1 needs to be adjusted, the fastening bolt is loosened. At this time, the first rod 11 and the second rod 12 are in an unlocked state. After the telescopic rod 1 is adjusted to the required length, the fastening bolt is tightened until it presses against the first rod. At this time, the first rod 11 and the second rod 12 are in a locked state.
[0025] In this embodiment, the flexible wheel frame 2 includes a left wheel frame arm 21 and a right wheel frame arm 22. One end of the left wheel frame arm 21 and one end of the right wheel frame arm 22 are hinged by a pivot 23. The pivot 23 is provided with a locking nut for locking the left wheel frame arm 21 and the right wheel frame arm 22. Magnetic moving wheels 24 are respectively installed on the left wheel frame arm 21 and the right wheel frame arm 22. In use, the flexible wheel frame 2 is magnetically attracted to the workpiece by the magnetic moving wheels 24, and the locking nut locks the pivot 23. Neither the left wheel frame arm 21 nor the right wheel frame arm 22 can rotate relative to the pivot 23. When it is necessary to adjust according to the curvature of the workpiece, the locking nut is loosened, the included angle between the left wheel frame arm 21 and the right wheel frame arm 22 is adjusted, and then the locking nut is tightened again.
[0026] In this embodiment, the telescopic rod 1 is fixed to the flexible wheel frame 2, and the distance between the two telescopic rods 1 is adjustable. Specifically, both the left wheel frame arm 21 and the right wheel frame arm 22 are provided with strip-shaped grooves 25, and a slider 26 is slidably connected within the strip-shaped grooves 25. The slider 26 includes a T-shaped block 261 and a back plate 262 connected by bolts. The slider 26 is generally I-shaped, and a through threaded hole is provided on the slider 26. The telescopic rod 1 is threadedly connected to the threaded hole of the slider 26. A locking structure is provided on the slider 26 to lock the slider 26 with the left wheel frame arm 21 or the right wheel frame arm 22. Specifically, the locking structure includes a locking bolt 27. The T-shaped block 261 in the slider 26 has a wing, and the locking bolt 27 is installed in the threaded hole of the wing. When locking the slider 26, the locking bolt 27 is tightened until the locking bolt 27 is pressed against the left wheel frame arm 21 or the right wheel frame.
[0027] Working principle: The length of the telescopic rod 1 is adjusted according to the distance the ultrasonic probe 3 needs to move. By adjusting the length of the rod to adapt to different moving distances, if the workpiece is a pipe, the angle between the left wheel arm 21 and the right wheel arm 22 is adjusted according to the curvature of the pipe. If the workpiece is a plate, the left wheel arm 21 and the right wheel arm 22 are adjusted to a straight line. Then, the probe auxiliary moving device is attracted to the workpiece by the magnetic moving wheel 24. The ultrasonic probe 3 is placed between the two telescopic rods 1. At this time, the probe can slide along the length of the rod. During the actual inspection, after the ultrasonic probe 3 completes one horizontal movement, the entire device is moved vertically by the magnetic moving wheel 24. This is repeated to complete the sawtooth scanning.
[0028] This invention uses an ultrasonic probe 3 with an auxiliary moving device to ensure that the probe is always perpendicular to the weld when moving, which can effectively improve detection efficiency and control the risk of missing defects during detection.
[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
