[0002] In the process of pipeline weld joint detection, ZK21 / 05-025 (XC) type manual scanning frame used in the phased array ultrasonic detection of Keji innovation is used, the scanning frame can be applied to double probe to simultaneously scan welding joint from single side, and the detection requirement of simultaneously scanning weld joint from two sides can be met by once scanning (without separately scanning from two sides), so that the detection efficiency is greatly improved.

[0003] The ZK21 / 05-025 (XC) type manual scanning frame is fixed by bridging mode using right probe, and the probe clamping part is located at the front 1 / 4 of the probe, when right probe scanning moves to six o'clock position, due to the gravity of probe and probe line, the rear end of right probe is tilted downward, so that the right scanning atlas loses detection data, which greatly affects the detection efficiency, and manual pressing the rear end of probe can make coupling agent flow to the operator, so as to cause inconvenience.

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] Example 1, as Figures 1-6 As shown, a device for fixing and positioning a phased array ultrasonic testing probe includes a pipe body 1, a support 2, and a testing component 3. The pipe body 1 is placed inside the support 2, and the testing component 3 is sleeved on the outside of the pipe body 1. The testing component 3 includes an installation chain 301, a first probe 302, a second probe 303, and a clamping unit 304. An L-shaped limiting plate 4 is provided on the outside of the second probe 303. A snap-fit ​​groove 5 is opened at the bottom of the horizontal section of the L-shaped limiting plate 4. The outside of the second probe 303 is snap-fitted into the snap-fit ​​groove 5. Two connecting holes 6 are opened on the vertical section of the L-shaped limiting plate 4 and are symmetrically distributed on the left and right. Nylon cable ties 7 are movably connected inside the connecting holes 6. The vertical section of the L-shaped limiting plate 4 is tied and fixed to the clamping unit 304 by the two nylon cable ties 7.

[0024] Specifically, the first probe 302 is fixedly installed inside the mounting chain 301, the clamping unit 304 is fixedly installed on the top of the mounting chain 301, the second probe 303 is hinged to the clamping unit 304, and both the first probe 302 and the second probe 303 are connected to external testing instruments through probe lines.

[0025] The size of the snap-fit ​​groove 5 is adapted to the outer size of the second probe 303. The installation position of the L-shaped limiting plate 4 is determined by first docking the snap-fit ​​groove 5 with the second probe 303. The L-shaped limiting plate 4 is then pushed toward the clamping unit 304 and inserted into the clamping unit 304. Then, the L-shaped limiting plate 4 is tied together with the clamping unit 304 by passing the nylon cable tie 7 through the connecting hole 6. This ensures that the L-shaped limiting plate 4 can restrict the second probe 303 after installation, and that it will not tilt downwards due to the weight of the probe and probe cable when the second probe 303 scans and moves to the six o'clock position.

[0026] Example 2 is a further improvement on Example 1, and is as follows: The clamping unit 304 includes a support base 3401, a horizontal bar 3402, a vertical bar 3403, a mounting rod 3404, a mounting block 3405, and a limiting block 3406. The support base 3401 is fixedly installed on the top of the mounting chain 301. The horizontal bar 3402 is disposed inside the support base 3401. The vertical bar 3403 is disposed inside the horizontal bar 3402. The mounting rod 3404 is fixedly installed on the bottom of the vertical bar 3403. There are two mounting blocks 3405, which are slidably installed on the front side of the mounting rod 3404. There are two limiting blocks 3406, which are fixed to the two mounting blocks 3405 by fasteners. Insertion rods 3407 are fixedly installed on the opposite sides of the two limiting blocks 3406, and extend into the interior of the second probe 303.

[0027] With this configuration, the distance between the two mounting blocks 3405 can be adjusted by the action of the mounting rod 3404, thereby completing the installation of the second probe 303.

[0028] Example 3 is a further improvement based on Example 2, and it is as follows: a dovetail groove 3408 is provided on the front side of the mounting rod 3404, and dovetail blocks 3409 are fixedly installed on the rear side of the two mounting blocks 3405. The two dovetail blocks 3409 are slidably connected to the dovetail groove 3408 respectively.

[0029] This design, through the cooperation of the dovetail block 3409 and the dovetail groove 3408, ensures that the mounting block 3405 remains stable after being installed by the mounting rod 3404, and facilitates easy disassembly.

[0030] Example 4 is a further improvement based on Example 2, and it is as follows: the two mounting blocks 3405 are provided with docking grooves 3410 on opposite sides, and the two limiting blocks 3406 are attached to the inside of the docking grooves 3410 on opposite sides.

[0031] This design allows the limiting block 3406 to quickly find its positioning point through the mating slot 3410 during installation, thus facilitating installation and improving the convenience of maintenance.

[0032] Example 5 is a further improvement based on Example 2, and it is as follows: the rear side of the vertical section of the L-shaped limiting plate 4 is attached to the front side of the two limiting blocks 3406, and the left and right sides of the vertical section of the L-shaped limiting plate 4 are attached to the opposite sides of the two mounting blocks 3405 respectively.

[0033] This configuration restricts the rear side and both sides of the vertical section of the L-shaped limiting plate 4, thereby maintaining stability during use after being fixed by the nylon cable ties 7, and enhancing the restriction effect on the second probe 303.

[0034] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
