Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe flaw detection, in particular to an ultrasonic oblique probe shoe. Background Art

[0002] The function of the ultrasonic oblique probe shoe is to fix and adjust the incident angle of the ultrasonic probe. It is crucial and indispensable in the ultrasonic testing process of seamless steel pipes. Therefore, it is necessary to ensure that the incident angle of the ultrasonic oblique probe shoe is perpendicular to the artificial flaw reflection surface of the oblique angle of the inspected sample pipe. To achieve this, it is necessary to involve how to adjust its incidence when testing steel pipes with different wall thicknesses and outer diameters to ensure that the echo signal with the maximum signal-to-noise ratio is obtained. Current technology cannot achieve the above.

[0003] To this end, we propose an ultrasonic oblique probe shoe to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an ultrasonic oblique probe shoe to solve the problem in the background art that the current technology cannot achieve adjustable incidence when flaw detection is performed on steel pipes with different wall thicknesses and outer diameters.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An ultrasonic oblique probe shoe comprises a probe, a probe shoe and a coupling water cavity. Two probe seats are mounted on the probe shoe. The connecting line of the center points of the two probe seats is inclined relative to the probe shoe, so that the probe has a deflection angle relative to the probe shoe. A probe hole 1 is provided in the probe seat. Two probe holes 2 are provided on the probe shoe, which correspond one-to-one with the two probe holes. Probe hole 1 is docked with probe hole 2. The probe passes through probe hole 1 to probe hole 2. Probe hole 1 is obliquely disposed in the probe seat, and probe hole 2 is obliquely disposed in the probe shoe, so that the probe has an incident angle in the probe shoe.

[0007] In a further embodiment, the contact surfaces between the probe shoe and the probe base are arc-shaped, and the probe shoe and the probe base are slidably connected to change the incident angle of the probe, and the probe shoe and the probe base are positioned by screws. The aperture of the probe hole 2 is larger than the aperture of the probe hole 1, so that when the probe base slides, the probe hole 2 provides sliding space for the probe.

[0008] In a further embodiment, the incident angle of the probe is 16.5°.

[0009] In a further embodiment, the deflection angle of the probe relative to the probe shoe is 6°.

[0010] In a further embodiment, the contact surface between the probe shoe and the probe base has a groove, and the probe base slides in the groove.

[0011] In a further embodiment, the probe base has angle scale lines.

[0012] In a further embodiment, the coupling water cavity is rectangular and has an oblique angle relative to the probe shoe.

[0013] Furthermore, the coupling water cavity has a deflection angle of 16.5° relative to the probe shoe.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The probe deflection angle of this probe shoe is 6°, which is designed to maintain perpendicularity to the defect at the maximum rolling angle of the steel pipe, effectively detecting artificial defects in this angle range. The incident angle of the probe is 16.5°, ensuring that the refraction angle of the ultrasonic beam in the steel pipe remains within 45°, ensuring that the maximum reflected defect signal is obtained. The deflection angle of the coupling water cavity is 16.5°, ensuring that the ultrasonic wave can effectively propagate to the surface of the steel pipe, thereby ensuring that the incident angle of the ultrasonic oblique probe shoe is perpendicular to the reflection surface of the artificial defect at the oblique angle of the inspected sample pipe. When inspecting steel pipes with different wall thicknesses and outer diameters, its incidence is adjustable to ensure that the echo signal with the maximum signal-to-noise ratio is obtained.

These terms are used solely to facilitate the description of the present invention and to simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3 , an ultrasonic oblique probe shoe, which includes a probe, a probe shoe 1 and a coupling water cavity 7, two probe seats 2 are installed on the probe shoe 1, and the connecting line of the center points of the two probe seats 2 is inclined relative to the probe shoe 1, so that the probe has a deflection angle relative to the probe shoe 1, the probe seat 2 has a probe hole 1 5, the probe shoe 1 has two probe holes 2 corresponding to the two probe holes 1 5, the probe hole 1 5 is connected to the probe hole 2, the probe passes through the probe hole 1 5 to the probe hole 2, the probe hole 1 5 is obliquely placed in the probe seat 2, and the probe hole 2 is obliquely placed in the probe shoe 1, so that the probe has an incident angle in the probe shoe 1.

[0024] Among them, in order to facilitate the processing and lightweight of the probe shoe, nylon material is used as the main material of the probe shoe, and in order to adjust the incident angle of the probe, the contact surfaces of the probe shoe 1 and the probe seat 2 are arc-shaped, and the probe shoe 1 and the probe seat 2 are slidingly connected to change the incident angle of the probe, and the probe shoe 1 and the probe seat 2 are positioned by screws. The aperture of the probe hole 2 is larger than the aperture of the probe hole 1 5. When the probe seat 2 slides, the probe hole 2 provides a sliding space for the probe, and the sliding of the probe seat 2 can adjust the angle. In order to ensure the accuracy of the adjustment angle, the probe seat 2 is provided with an angle scale line 4, and the contact surface of the probe shoe 1 and the probe seat 2 is provided with a groove 3. The probe seat 2 slides in the groove 3. Under the limitation of the groove 3, the incident angle of the probe is prevented from being changed when the incident angle of the probe is adjusted.

[0025] The probe deflection angle of 6° is to keep it perpendicular to the defect of the maximum rolling angle of the steel pipe, and effectively detect artificial defects in this angle range. The mounting hole 6 is to fix the probe position. The fixing method adopts the pressure cover method, and the two oblong holes of the pressure cover are fastened with screws. When fine-tuning the incident angle of the probe, the two screws need to be loosened. After the defect signal is adjusted, the screws are tightened. The incident angle of the probe is 16.5° to fix the incident angle of the ultrasonic probe, ensuring that the refraction angle of the ultrasonic beam in the steel pipe remains within 45°, ensuring that the maximum reflected defect signal is obtained. The coupling water cavity 7 is rectangular, and its deflection angle relative to the probe shoe 1 is 16.5°, ensuring that the ultrasonic wave can effectively propagate to the surface of the steel pipe. The coupling water cavity 7 needs to be continuously filled with water by a water pump to keep the water in the water cavity saturated. The coupling water is mainly used to eliminate air.
