Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flaw detection, in particular to an ultrasonic flaw detection device for non-destructive testing of metals. Background Art

[0002] Ultrasonic metal flaw detection utilizes the principle that ultrasonic waves, when propagating through metal, are reflected upon imperfections. The probe transmits ultrasonic waves, which are then transferred to the metal via a coupling agent. Upon encountering imperfections or the bottom surface, they are reflected back to the probe and converted into electrical signals for display. Ultrasonic flaw detection can detect defects such as internal cracks and pores, offering advantages such as high sensitivity and fast operation, making it widely used in metal component inspection.

[0003] Traditionally, flaw detection on metal pipes involves manually moving handheld flaw detection equipment across the metal surface, relying on ultrasonic waves emitted by the equipment to detect the metal material. To improve detection accuracy and reduce wear on the metal surface, a coupling agent must be added to the flaw detection equipment and the metal surface. However, since the stability of the manually moved flaw detection equipment cannot be guaranteed, the distance between the flaw detection equipment probe and the metal surface cannot be kept consistent, which leads to a decrease in flaw detection accuracy.

[0004] Based on this, an ultrasonic flaw detection device for metal non-destructive testing is proposed. Utility Model Content

[0021] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0023] An ultrasonic flaw detection device for non-destructive testing of metals includes a connecting frame 1. The connecting frame 1 has a U-shaped structure. A support rod 2 and a sliding rod 3 are connected to the connecting frame 1. The support rod 2 is vertically arranged. The structural stability of the connecting frame 1 set on the ground is improved by arranging the support rod 2. The sliding rod 3 is horizontally arranged. A sliding sleeve 11 is slidably connected to the sliding rod 3. A moving block 7 is slidably connected below the sliding sleeve 11. A detection block 9 is connected to the moving block 7. The detection block 9 can emit ultrasonic waves to detect metal pipes. The defects in the pipes can be understood by relying on the difference in the reflected waves of the ultrasonic waves contacting the metal pipes. One end of the moving block 7 is connected to a transmission mechanism for driving the moving block 7 to move below the sliding rod 3.

[0024] Specifically, such as Figure 3 As shown, the upper end of the movable block 7 is connected to a water pipe 8, and a button 17 is connected to the water pipe 8. The button 17 is arranged directly above the movable block 7. When the button 17 is pressed, the water pipe 8 can spray coupling agent to lubricate the inspection part. One end of the water pipe 8 is connected to an external coupling agent delivery pipeline.

[0025] Specifically, such as Figure 2 As shown, the lower end of the sliding sleeve 11 is connected to the vertical rod 2 12, and the moving block 7 is slidably connected to the vertical rod 2 12. During detection, the moving block 7 is always located at the upper end of the vertical rod 2 12. After the detection is completed, the moving block 7 will slide to the lower end of the vertical rod 2 12.

[0026] Specifically, such as Figure 2 As shown, a threaded rod 10 is connected to the lower end of the detection block 9, and the threaded rod 10 is threadedly connected to the moving block 7. By rotating the threaded rod 10, the distance between the detection block 9 and the metal pipe can be changed.

[0027] Specifically, such as Figure 3 As shown, the transmission mechanism includes a deflection block 14, which is slidably connected to a vertical rod 6, and the upper end of the vertical rod 6 is connected to a bending plate 13. The bending plate 13 is connected to a traction shaft 16, and the traction shaft 16 is rotatably connected to one end of the moving block 7. A circular hole groove is opened at one end of the moving block 7, and one end of the traction shaft 16 is rotatably connected to the circular hole groove of the moving block 7. A spring 15 is connected between the deflection block 14 and the bending plate 13. By setting the spring 15, the bending plate 13 is moved away from the deflection block 14, and the spring 15 structure is in a compressed state.

[0028] Specifically, such as Figure 1 As shown, a crank 5 is connected to one side of the deflection block 14, and a connecting column 4 is connected to the lower end of the connecting frame 1. The crank 5 is rotatably connected to the connecting column 4. During testing, the operator only needs to rotate the crank 5.

[0029] In summary, the ultrasonic flaw detection device for non-destructive testing of metal provided in this embodiment can place the metal pipe on the connecting frame 1 when it is necessary to perform flaw detection on the metal pipe, and the operator starts the detection block 9, wherein the detection block 9 needs to abut against the surface of the pipe. In order to reduce wear, a coupling agent needs to be added between the structures to reduce the wear between the structures. The detection block 9 is connected to the data processing terminal through a lead. After the detection block 9 is started, the inspector only needs to pull the crank 5 to make the crank 5 change from a state deflected to one side to a state deflected to the other side.

[0030] When the crank 5 is deflected, the deflection block 14 connected to one end of the crank 5 is deflected, thereby driving the vertical rod 6 to rotate. The spring 15 can ensure that the bending plate 13 is always away from the deflection block 14, thereby ensuring that the moving block 7 can always press the button 17 during detection, thereby automatically opening the water pipe 8 during detection, adding coupling agent to the detection position, and improving detection accuracy.

[0031] When the detection is completed, the crank 5 continues to deflect, and the moving block 7 can slide to the lower end of the vertical rod 2 12 and maintain the state of sliding to the lower end of the vertical rod 2 12.

[0032] The above description of the embodiments is intended to enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
