[0002] The ultrasonic detection probe is an important component of the ultrasonic detection system. Its function is to convert electrical energy into ultrasonic waves and transmit the ultrasonic waves to the object to be detected. At the same time, it receives the ultrasonic waves reflected from the object and converts them into electrical energy, thereby detecting the thickness of the object.

[0003] During the non-destructive ultrasonic testing (ultrasonic dimensional testing) of steel and metal materials, the probe needs to be fitted with the object to be tested to ensure that the ultrasonic wave can effectively enter and propagate. Currently, the commonly used probes need to be manually pressed and fitted with the object to be tested. After releasing the hand, the probe is easy to slip, affecting the detection efficiency and stability. In addition, manually pressing the probe will also cause fatigue and inconvenience to the operator. Utility Model Content

[0022] See also Figure 1-4 The utility model provides a technical solution: a new type of probe for ultrasonic size detection equipment for pipes, including a connecting frame 1, a mounting assembly 2 and an ultrasonic probe 3 installed on the mounting assembly 2, the connecting frame 1 includes an arc-shaped connecting plate 11, the mounting assembly 2 is arranged on the lower side of the arc-shaped connecting plate 11, and the two opposite sides of the arc-shaped connecting plate 11 are fixedly connected with an n-type bracket 12, a roller 13 is arranged between the two vertical plates of the n-type bracket 12, a rotating shaft 15 is fixedly connected between the two vertical plates of the n-type bracket 12, a rotating hole 16 is opened on the roller 13, and the roller 13 is rotatably sleeved on the outer surface of the rotating shaft 15 through the rotating hole 16, and the outer surface of the roller 13 is inlaid with an annular block 14, and the annular block 14 is a permanent magnet.

[0023] When the probe needs to be placed on a steel pipe and the thickness of the steel pipe is detected, the connecting frame 1 is placed on the outer surface of the steel pipe. Since the annular block 14 is a permanent magnet, the roller 13 can be adsorbed on the outer surface of the steel pipe. In this way, when the ultrasonic probe 3 is detecting the steel pipe, the staff does not need to hold the ultrasonic probe 3 with their hands all the time, which reduces the burden on the staff. At the same time, when the detection position of the steel pipe needs to be adjusted, it is only necessary to push the connecting frame 1, so that the roller 13 can drive the ultrasonic probe 3 to move on the surface of the steel pipe, which is more convenient when detecting the steel pipe.

[0024] Specifically, the mounting assembly 2 includes a mounting block 21, which has a mounting hole 22. The ultrasonic probe 3 is placed in the mounting hole 22. Four arc-shaped clamps 23 arranged in a circular array are provided in the mounting hole 22. The arc-shaped clamps 23 are fitted with the outer surface of the ultrasonic probe 3. Four contraction cavities 25 are provided in the mounting block 21. A push rod 26 is fixedly connected to the surface of the arc-shaped clamp 23 close to the contraction cavity 25. The other end of the push rod 26 slides into the contraction cavity 25. A sliding plate 27 is fixedly connected to one end of the push rod 26 located in the contraction cavity 25. The sliding plate 27 slides in the contraction cavity 25. A tension spring 28 is fixedly connected between the sliding plate 27 and the inner wall of the contraction cavity 25. The tension spring 28 is movably sleeved on the outer surface of the push rod 26.

[0025] When the ultrasonic probe 3 is extended between the four arc-shaped clamping plates 23, the surface of the ultrasonic probe 3 will squeeze the arc-shaped clamping plates 23, causing the arc-shaped clamping plates 23 to move outward. At the same time, the push rod 26 pushes the sliding plate 27 to slide in the contraction cavity 25. At the same time, the tension spring 28 is stressed and stretched. When the ultrasonic probe 3 is installed in the mounting hole 22, the outer surface of the ultrasonic probe 3 no longer squeezes the arc-shaped clamping plates 23. At this time, the tension spring 28 will release the reverse pulling force, so that the arc-shaped clamping plates 23 form a clamping effect on the ultrasonic probe 3, thereby avoiding the problem of loosening of the ultrasonic probe 3 after installation.

[0026] Specifically, an inclined plate 24 inclined outward is fixedly connected to the upper side of the arc-shaped clamping plate 23 , so that it is convenient to insert the ultrasonic probe 3 between the four arc-shaped clamping plates 23 .

[0027] Specifically, a pulling rod 29 is fixedly connected to the upper surface of the mounting block 21, and the upper end of the pulling rod 29 slides through the upper surface of the arc-shaped connecting plate 11. A pulling block 210 is fixedly connected to the upper end of the pulling rod 29. A spring 211 is fixedly connected between the mounting block 21 and the lower surface of the arc-shaped connecting plate 11. The spring 211 is movably sleeved on the outer surface of the pulling rod 29. When the spring 211 is not squeezed, the spring 211 will form a thrust on the mounting block 21. The arrangement of such a structure makes the ultrasonic probe 3 closer to the outer surface of the steel pipe, thereby ensuring the use effect of the ultrasonic probe 3.

[0028] Working principle: When the ultrasonic probe 3 is inserted between the four arc-shaped clamping plates 23, the surface of the ultrasonic probe 3 will squeeze the arc-shaped clamping plates 23, causing the arc-shaped clamping plates 23 to move outward, and at the same time, the push rod 26 pushes the sliding plate 27 to slide in the contraction cavity 25, and at the same time, the tension spring 28 is stressed and stretched. When the ultrasonic probe 3 is installed in the installation hole 22, the outer surface of the ultrasonic probe 3 no longer squeezes the arc-shaped clamping plates 23, and the tension spring 28 releases the reverse pulling force, so that the arc-shaped clamping plates 23 form a clamping effect on the ultrasonic probe 3;

[0029] When the probe needs to be placed on a steel pipe and the thickness of the steel pipe is detected, the connecting frame 1 is placed on the outer surface of the steel pipe. Since the annular block 14 is a permanent magnet, the roller 13 can be adsorbed on the outer surface of the steel pipe. In this way, when the ultrasonic probe 3 is detecting the steel pipe, the staff does not need to hold the ultrasonic probe 3 with their hands all the time. When the detection position of the steel pipe needs to be adjusted, it is only necessary to push the connecting frame 1, so that the roller 13 can drive the ultrasonic probe 3 to move on the surface of the steel pipe.
