Description

Technical Field

[0001] This utility model belongs to the field of precast pipe pile construction technology, and in particular relates to a precast pipe pile welding quality inspection device. Background Technology

[0002] Currently, in many pipe pile construction projects, the lack of clear specific testing methods provided by the standards leads to uncertainty in the quality inspection of solid welds. Among commonly used non-destructive testing methods for welds, radiographic testing mainly detects internal weld defects and has high sensitivity for volumetric defects; however, when using radiographic testing on pipe pile welds, qualified weld images cannot be obtained on the film. Magnetic particle testing mainly detects surface and near-surface defects. Penetrant testing mainly detects surface opening defects; however, when using penetrant testing on pipe pile welds, the detection efficiency is low and defects are not easily identified. Ultrasonic testing mainly detects internal weld defects and has high sensitivity for area-shaped defects; however, conventional ultrasonic testing of welds can only detect small-scale defects at the weld root, resulting in missed detections.

[0003] Therefore, it is necessary to design a precast pipe pile welding quality inspection device to solve the above problems. Utility Model Content

[0028] Two magnetic bases 4 are respectively set at the ends of two adjacent precast pipe piles 1 that are close to each other;

[0029] A signal transmitter, detachably mounted on a magnetic base 4, is used to transmit detection signals.

[0030] The signal receiver 8 is detachably mounted on another magnetic base 4. The signal receiver 8 is electrically connected to the data analysis terminal 5. The signal receiver 8 is used to receive the detection signal emitted by the signal transmitter and transmit the detection signal to the data analysis terminal 5.

[0031] The signal transmitter can emit a linear constant amplitude signal. In this invention, the linear constant amplitude signal is selected as the Chrip signal.

[0032] The signal receiver 8 uses a MEMS type accelerometer with a signal bandwidth of 1Hz to 12KHz and a sensitivity of 10mV / g. The signal receiver 8 is provided with bolt holes 9 that mate with the connecting bolts 7. The signal receiver 8 is electrically connected to the data analysis terminal 5 through wires 10.

[0033] The data analysis terminal 5 is equipped with supporting software for spectrum analysis, using superior frequencies to judge the quality of welds.

[0034] At least three sets of data were collected at each measurement point, and the average value of the dominant frequency was taken as the final test result.

[0035] Further optimization of the scheme: the magnetic base 4 is rectangular, and the magnetic base 4 is bent into an arc along its long side, with the radius of the arc matching the radius of the precast pipe pile 1.

[0036] The magnetic base measures 4cm in length and 2cm in width.

[0037] The design has been further optimized so that handles 6 are fixedly connected to the two short sides of the magnetic base 4.

[0038] The design was further optimized by making handle 6 curved.

[0039] The radius of the arc of handle 6 is 1cm.

[0040] In a further optimized design, a connecting bolt 7 is provided at the center of the magnetic base 4, and the signal transmitter and / or signal receiver 8 can be detachably mounted on the magnetic base 4 via the connecting bolt 7.

[0041] The length of connecting bolt 7 is 0.5cm.

[0042] The scheme was further optimized so that the signal transmitter and signal receiver 8 were symmetrically arranged on both sides of the weld 3 formed at the two precast pipe piles 1 that were close to each other.

[0043] Further optimization of the scheme: the distance between the signal transmitter and signal receiver 8 and the weld 3 is D, where 4cm < D < 5cm.

[0044] The testing process for this utility model is as follows:

[0045] S1. Measure the dominant frequency f0 of the precast pipe pile 1 as the benchmark data for judging the welding quality of the precast pipe pile 1.

[0046] S2. Determine the measuring points of precast pipe pile 1. Draw the measuring points within a range of 4cm-5cm from weld 3, with a spacing of 5cm between the measuring points.

[0047] S3. Use sandpaper to remove rust, dust, etc. from the test point.

[0048] S4. Install the signal transmitter and signal receiver 8 on the magnetic base 4, and install the magnetic base 4 on the measuring point position marked on the end steel plate 2.

[0049] S5. At least 3 sets of data should be detected at each measurement point, and the average value of the dominant frequency f should be taken as the final detection result.

[0050] When f≠f0, the weld is defective.

[0051] When f = f0, the weld is intact.

[0052] S6. Repeat step S5 to generate weld inspection results.
