The main function of ultrasonic phased array delamination and non-delamination automatic detection of steel plates is to detect internal defects in the steel plate, and the stability of the ultrasonic phased array delamination and non-delamination automatic detection equipment is the guarantee for the detection of internal defects in the steel plate.

[0003] Typically, due to human error or equipment limitations during testing, internal defects in steel plates may be missed, or improper post-testing processing may occur, making it impossible to guarantee the accuracy of the tests and the quality of the plates. Summary of the Invention

Each detection probe performs ultrasonic phased array detection of internal non-layered defects in the target steel plate from multiple angles, with the range of these multiple angles being 30° to 75°.

[0013] The beneficial effects of this invention are: (1) The present invention installs four detection probes on the probe mounting base and arranges the four detection probes in a rectangular distribution, which can detect different positions of the steel plate to be tested, thus ensuring detection quality and efficiency.

[0014] (2) In this invention, the probe pressure plate covers the detection probe, restricting the probe's vertical freedom.

Detailed Implementation

[0019] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0020] Figure 1 This is a schematic diagram of the structure of the ultrasonic phased array layered and non-layered reverse combination detection device for steel plates provided in this application embodiment. The device includes a water-separating mechanism base shell 1, a probe mounting base 2, and a detection probe. Specifically, the probe mounting base 2 is detachably mounted on top of the base shell 1 of the water distribution mechanism via mounting bolts. See also Figure 1 The center of probe mounting base 2 is aligned with the center of probe mounting base 2, and four mounting bolts are located at the four corners of probe mounting base 2. A cavity for accommodating the coupling medium is formed between probe mounting base 2 and the bottom shell 1 of water distribution mechanism. Quick-release plug 11 of water distribution mechanism is located in the middle of probe mounting base 2 and is installed with a sealed structure to prevent leakage.

[0021] Preferably, the bottom shell 1 of the water distribution mechanism is designed with a concave structure to facilitate the formation of a water film.

[0022] The detection probe is fixedly mounted on the probe mounting base 2. (See also...) Figure 1There are four detection probes: the first detection probe 3, the second detection probe 4, the third detection probe 5, and the fourth detection probe 6. The four detection probes are arranged in a rectangular pattern, that is, the four detection probes are located on the four sides of the same rectangle, and the center of the rectangle containing the four detection probes is aligned with the center of the probe mounting base 2.

[0023] The probe mounting base 2 has mounting slots corresponding to the positions of each detection probe. Each detection probe is located in its corresponding mounting slot, and its vertical freedom is restricted by probe pressure plates 7, meaning each probe pressure plate 7 covers the corresponding detection probe. See [link to relevant documentation] Figure 1 Both ends of the probe pressure plate 7 are mounted on the probe mounting base 2 via first locking bolts 8. The first locking bolts 8 are set in the vertical direction, and the vertical gap of the probe can be adjusted by rotating the first locking bolts 8.

[0024] A locking plate 9 is also installed on the probe mounting base 2, and the locking plate 9 covers the corresponding probe pressure plate 7. Both ends of each locking plate 9 are installed on the probe mounting base 2 by a second locking bolt 10 set in the vertical direction. The locking plate 9 limits the probe pressure plate 7, thereby ensuring the limiting effect on the detection probe.

[0025] By setting up four detection probes arranged in a rectangular pattern, different locations on the steel plate to be inspected can be detected, ensuring both inspection quality and efficiency.

[0026] In addition, this application also provides a method for detecting layered and non-layered reverse combinations of ultrasonic phased array detectors for steel plates, which is based on the aforementioned detection device for layered and non-layered reverse combinations of ultrasonic phased array detectors for steel plates. See also Figure 2 The detection method includes the following steps: Step S1: Each detection probe detects internal delamination defects in the target steel plate using 0° angle ultrasonic phased array coupling.

[0027] Specifically, with Figure 2 For example, the first probe performs ultrasonic phased array coupling monitoring and detection of internal delamination defects in the target steel plate at a 0° angle (i.e., Figure 2 (12) The fourth probe performs ultrasonic phased array coupling monitoring and detection of internal delamination defects in the target steel plate at a 0° angle (i.e., Figure 2 13 in the middle.

[0028] Step S2: Each detection probe performs ultrasonic phased array detection on the target steel plate for internal non-layered defects through continuous multi-angle detection; the continuous multi-angle range is 30°~75°.

[0029] Specifically, with Figure 2For example, the first probe uses an ultrasonic phased array to detect internal non-layered defects (i.e., defects in the target steel plate) at an angle of 30° to 75°. Figure 2 (14) The fourth probe performs ultrasonic phased array detection at an angle of 30°~75° to detect internal non-layered defects in the target steel plate (i.e., Figure 2 15 in the middle.

[0030] Therefore, the technical solution of this application installs four detection probes on the probe mounting base 2 and arranges the four detection probes in a rectangular distribution, which can detect different positions of the steel plate to be tested, ensuring detection quality and efficiency.

[0031] In addition to the above embodiments, the present invention may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
