Abstract
Description
Technical Field
[0001] The present application relates to the field of ultrasonic detection technology, and in particular to an ultrasonic detection device for detecting pile foundation defects. Background Art
[0002] Common methods for concrete pile foundation testing include core sampling, low-strain testing, and ultrasonic testing. Ultrasonic flaw detection uses the ability of ultrasound to penetrate deep into metal materials and reflect at the interface edge when entering from one section to another to inspect for defects in parts. When the ultrasonic beam passes from the surface of the pile foundation through the probe into the interior of the pile foundation, reflected waves are generated when it encounters defects and the bottom surface of the part. The location and size of the defect can be determined based on these waveforms.
[0003] During ultrasonic testing, the sound wave transducer needs to fit tightly to the surface of the object to be tested, and this is usually done by holding a handheld transducer. However, the handheld transducer is easily affected by human factors, resulting in transducer displacement and inconsistent pressure on the surface of the object to be tested by the transducers on both sides, which will cause serious interference with the test results. Especially for long-term sample testing, it is difficult for the handheld transducer to maintain the same pressure and position on the surface of the test sample, resulting in errors in the test data and affecting the test results. In addition, during the test process, the distance between the two transducers is often measured by a tape measure, which can easily cause detection errors, thereby affecting the test results and making the test efficiency low.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.
[0020] The present invention provides an ultrasonic detection device for detecting pile foundation defects. Figure 1 As shown, it includes a support member 1, two connecting members 2 and two sound wave transducers 3; the support member 1 includes a fixed rod 11 and a telescopic rod 12; the telescopic rod 12 is arranged inside the fixed rod 11 and is slidably connected to the fixed rod 11; one end of one of the connecting members 2 is sleeved on the outside of the fixed rod 11, and the other end thereof is connected to one of the sound wave transducers 3; one end of the other connecting member 2 is sleeved on the outside of the telescopic rod 12, and the other end thereof is connected to the other sound wave transducer 3.
[0021] For example, one of the connecting parts 2 is fixedly connected to a suitable position of the fixed rod 11, and the other connecting part 2 is fixedly connected to a suitable position of the telescopic rod 12. The distance between the two connecting parts 2 can be adjusted by sliding the telescopic rod 12 in the fixed rod 11, that is, the distance between the two acoustic wave transducers 3 can be adjusted by sliding the telescopic rod 12 in the fixed rod 11, thereby meeting the requirements of pile foundation defect detection.
[0022] For example, two acoustic wave transducers 3 can be placed at the target position of the pile foundation to be tested through the support member 1 and two connecting members 2, and the distance between the two acoustic wave transducers 3 can be adjusted to meet the detection needs; manually pressing the support member 1 can make the forces on the two acoustic wave transducers 3 the same, thereby reducing the error of the detection data.
[0023] In the embodiment of this application, Figure 1As shown, the two connecting parts 2 each include a hoop sleeve 21 and an adjusting rod 22; one of the hoop sleeves 21 is sleeved on the outside of the fixed rod 11, and the other hoop sleeve 21 is sleeved on the outside of the telescopic rod 12; one end of one adjusting rod 22 is connected to one of the hoop sleeves 21, and the other end of one adjusting rod 22 is connected to one of the acoustic transducers 3; one end of the other adjusting rod 22 is connected to the other hoop sleeve 21, and the other end of the other adjusting rod 22 is connected to the other acoustic transducer 3.
[0024] Exemplarily, the two hoop sleeves 21 are respectively adapted to the shapes of the fixed rod 11 and the telescopic rod 12, thereby ensuring that they are stably installed on the fixed rod 11 or the telescopic rod 12. The outer side of the hoop sleeve 21 is fixedly connected to the adjusting rod 22. The two adjusting rods 22 have the same length. When the two acoustic wave transducers 3 are working, the two adjusting rods 22 of the same length can ensure that the two acoustic wave transducers 3 are subjected to the same force, thereby reducing the error of the detection data.
[0025] Exemplarily, fastening bolts are provided on the two hoop sleeves 21. After the two hoop sleeves 21 are adjusted to appropriate positions, the two hoop sleeves 21 can be fixedly connected to the fixed rod 11 and the telescopic rod 12 respectively through the fastening bolts.
[0026] In the embodiment of this application, Figure 1 As shown, the adjustment rod 22 includes a first vertical rod 221 and a second vertical rod 222; one end of the first vertical rod 221 is connected to the hoop sleeve 21, the other end of the first vertical rod 221 is slidingly connected to one end of the second vertical rod 222, and the other end of the second vertical rod 222 is connected to the acoustic transducer 3.
[0027] Exemplarily, the first vertical rod 221 is fixedly connected to the hoop sleeve 21, the second vertical rod 222 is slidingly connected to the first vertical rod 221, and the acoustic wave transducer 3 is connected to the end of the second vertical rod 222 away from the support member 1. The distance between the acoustic wave transducer 3 and the support member 1 can be adjusted through the second vertical rod 222 to meet the actual application on site.
[0028] Exemplarily, a threading hole for routing the acoustic wave transducer 3 is provided on the side wall of the second vertical rod 222 .
[0029] In the embodiment of this application, Figure 1 As shown, the connecting member 2 further includes a fastener 23 ; the fastener 23 is connected to the second vertical rod 222 , and the end of the fastener 23 abuts against the first vertical rod 221 .
[0030] Exemplarily, the fastener 23 is configured as a fastening nut; when adjusting the distance between the acoustic wave transducer 3 and the support member 1, the second vertical rod 222 is made to slide on the first vertical rod 221. After sliding to the target position, the second vertical rod 222 can be positioned by the fastener 23 to prevent it from sliding on the first vertical rod 221.
[0031] For example, the first vertical rod 221 is provided with scale lines to facilitate manual adjustment of the second vertical rod 222 to an accurate position, and no additional measuring tools are needed to manually detect the position of the acoustic wave transducer 3 .
[0032] In the embodiment of this application, Figure 1 As shown, scale lines are provided on both the fixed rod 11 and the telescopic rod 12;
[0033] For example, when adjusting the horizontal distance between the two sound wave transducers 3, it is necessary to adjust the relative distance between the telescopic rod 12 and the fixed rod 11. Setting scales on the fixed rod 11 and the telescopic rod 12 can facilitate manual adjustment of the horizontal distance between the two sound wave transducers 3. There is no need to use additional measuring tools to detect the position of the sound wave transducers 3, and the technical effect of efficiently adjusting the sound wave transducers 3 can be achieved.
[0034] In the embodiment of this application, Figure 1 As shown, it also includes a handle 4; one end of the handle 4 is sleeved on the outside of the fixing rod 11 and is slidably connected to the fixing rod 11; the other end of the handle 4 extends outward in the radial direction of the fixing rod 11.
[0035] Exemplarily, the handle 4 is configured as a T-shaped handle 4 to facilitate manual operation.
[0036] Exemplarily, the handle 4 can slide on the fixed rod 11, and the handle 4 can be manually adjusted so that the handle 4 is always in the middle position between the two acoustic wave transducers 3, thereby ensuring that when the handle 4 is manually operated to perform ultrasonic testing, the forces acting on the two acoustic wave transducers 3 are equal, thereby reducing the error of the detection data and improving the detection efficiency.
[0037] Exemplarily, a fastening bolt is provided on the handle 4 . After the handle 4 is adjusted to the center position of the two acoustic wave transducers 3 , the handle 4 can be fixedly connected to the fixed rod 11 or the telescopic rod 12 manually by fastening the bolt.
[0038] In the embodiment of this application, Figure 1 As shown, a quick buckle 5 is also included; the acoustic wave transducer 3 is connected to the second vertical rod 222 through the quick buckle 5.
[0039] In the embodiment of this application, Figure 1As shown, a through slot is formed on the hoop sleeve 21 , and the center of the through slot coincides with the axis of the acoustic wave transducer 3 .
[0040] For example, the through slots formed on the hoop sleeve 21 enable manual reading of the scale lines on the fixed rod 11 and the telescopic rod 12 , thereby enabling determination of the distance between the two acoustic wave transducers 3 .
