Description

Technical Field

[0001] This utility model relates to the field of quality inspection, and in particular to an adaptive moving seat, a probe clamping device, and a phased array ultrasonic testing system. Background Technology

[0002] Weld inspection is a crucial link in modern industrial quality control systems, specifically referring to a set of techniques that utilize a series of non-destructive or minimal-destructive methods to comprehensively evaluate welded joints. Its core objective is to identify various defects (such as cracks, porosity, lack of fusion, and slag inclusions) inside and on the surface of the weld, measure key geometric dimensions (penetration depth, reinforcement height, misalignment, etc.), and determine whether it meets the requirements for structural integrity, mechanical properties, and service safety according to stringent standards. The five traditional non-destructive testing (NDT) methods form the foundation: Visual inspection (VT) is used for rapid screening of surface defects; Radiographic testing (RT) uses the penetrating power of X / γ rays to visually present two-dimensional images of internal defects; Ultrasonic testing (UT), especially advanced phased array (PAUT) and time-of-flight diffraction (TOFD) techniques, can accurately locate deep defects and quantify their dimensions, particularly suitable for thick-walled structures; Magnetic particle testing (MT) has high sensitivity for surface and near-surface cracks in ferromagnetic materials; and Penetrant testing (PT) effectively detects surface opening defects in non-porous materials.

[0003] Existing weld inspection equipment is highly dependent on manual labor, often requiring manual hand-held operation. Prolonged hand-held operation can easily lead to operator fatigue, causing fluctuations in inspection distance, resulting in decreased inspection accuracy and deviation of the scanning trajectory.

[0004] Therefore, those skilled in the art are dedicated to developing an adaptive moving seat, a probe clamping device, and a phased array ultrasonic testing system. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is to provide an adaptive moving seat, a probe clamping device and a phased array ultrasonic testing system.

[0006] To achieve the above objectives, this utility model provides an adaptive mobile seat, including a base, the bottom of which is provided with at least one set of adsorption crawling mechanisms, the adsorption crawling mechanisms including magnetic components and bearings.

[0007] Preferably, the base has axially extending relief grooves on both sides of its bottom, and a connecting shaft is provided in the relief groove, which is fixedly connected to the adsorption crawling mechanism.

[0008] Preferably, the magnetic component is a magnetic wheel, and the outer diameter of the bearing is larger than the outer diameter of the magnetic wheel.

[0009] This utility model also provides a probe clamping device, including a detection probe and an adaptive moving seat as described above.

[0010] Preferably, it also includes a clamping seat, the position of which is adjustable relative to the base.

The two ends of the connecting rod are detachably connected to the first connecting plate and the second connecting plate, respectively.

[0016] The beneficial effects of this utility model are: it has a simple structure, low manufacturing cost, and extremely high adaptability. Specifically, the base design of this application provides stable support for the detection probe while allowing it to be directly adsorbed onto the surface of the welded tube (or plate) and moved flexibly.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that in the description of the present invention, terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific manner. Therefore, they should not be construed as limitations on the present invention. Terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] like Figure 1-3 As shown, this utility model provides an adaptive moving seat, including a base 11. The base 11 serves as the mounting foundation, and its cross-section is a square structure with an opening on one side. This design maximizes weight reduction and material savings without compromising structural strength, and provides a mounting foundation for subsequent components. In other embodiments, the base 11 can be configured with other shapes, such as circular, elliptical, or other irregular shapes, depending on actual needs. Furthermore, the bottom of the base 11 is provided with at least one set of adsorption crawling mechanisms 12. The adsorption crawling mechanism 12 includes a magnetic component 121 and a bearing 122. By setting the adsorption crawling mechanism 12, the base 11 can adsorb onto the welded pipe 4 while also moving on the welded pipe 4. Specifically, axially extending clearance grooves 11a are provided on opposite sides of the bottom of the base 11. A connecting shaft 13 is provided within the clearance groove 11a. The magnetic component 121 and the bearing 122 are spaced apart and pass through the connecting shaft 13, which provides a mounting foundation for the magnetic component 121 and the bearing 122. In practical implementation, since the welded pipe 4 to be tested is mostly made of metal, the magnetic component 121 can be used to provide magnetic force to attract the base 11 onto the welded pipe 4. The function of the bearing 122 is to convert the sliding friction of the base 11 into rolling friction, thereby reducing friction and facilitating the movement of the base 11. Similarly, in other embodiments, the magnetic component 121 can be replaced with other shapes or other similar products, and the bearing 122 can be replaced with rollers, rotating wheels, or other similar products.

[0024] In this embodiment, the magnetic component 121 is a magnetic wheel 121a, and the outer diameter of the magnetic wheel 121a is smaller than the outer diameter of the bearing 122. The main purpose of setting the magnetic component 121 in a wheel shape is to provide stronger radial magnetic force while also facilitating the movement of the base 11. Specifically, multiple tests have shown that the optimal effect is achieved when the difference between the outer diameters of the magnetic wheel 121a and the bearing 122 is 0.5 mm. If the difference is too small, the magnetic force of the magnetic wheel 121a will be too large, and the attraction force will be too strong, causing the base 11 to be obstructed from moving. If the difference is too large, the magnetic force of the magnetic wheel 121a will be too small, and the attraction force will be insufficient, causing the base 11 to easily detach.

[0025] This utility model also provides a probe clamping device, including a detection probe 25 and an adaptive moving base as described above. Further, it also includes a clamping base 24, the position of which is adjustable relative to the base 11. Specifically, the base 11 has an axially extending first sliding groove 21, within which a sliding rod 22 is slidably fitted. The first sliding groove 21 provides a mounting base for the sliding rod 22, which can reciprocate along the first sliding groove 21. In this embodiment, the sliding fit is a clearance fit. Further, a bracket 23 extending vertically along the axis of the base 11 is fixedly connected to the sliding rod 22. A second sliding groove 23a is provided on the side wall of the bracket 23, and the clamping base 24 is slidably fitted within the second sliding groove 23a. The bracket 23 provides a mounting base for the clamping base 24, which can reciprocate vertically along the second sliding groove 23a on the bracket 23.

[0026] In this embodiment, the clamping base 24 includes a top plate 241 and a side plate, with an elastic element 242 provided on the top plate 241. In this embodiment, the clamping base 24 provides a mounting base for the detection probe 25 to fix it, while the elastic element 242 is a compression spring. In other embodiments, the elastic element 242 can also be set as other similar elastic products such as a butterfly spring, wave spring, or ring spring. In actual use, one end of the elastic element 242 is connected to the top plate 241, and the other end is connected to the detection probe 25. At this time, the elastic element 242 is in a pre-compressed state, and the detection probe 25 remains in contact with the surface of the welded pipe 4 under the elastic reset action of the elastic element 242 to ensure detection accuracy. Furthermore, in this embodiment, a mounting plate 26 is also provided at the end of the base 11 away from the clamping base 24. An encoder (not shown in the figure) is provided on the mounting plate 26 to record the movement trajectory of the base 11.

[0027] like Figure 4As shown, this utility model also provides a phased array ultrasonic testing system, including at least two sets of probe clamping devices as described above. In addition, a first connecting plate 31 and a second connecting plate 32 extending axially along the base 11 are respectively provided on both sides of the probe clamping device. A connecting rod 33 is provided between the first connecting plate 31 and the second connecting plate 32, and both ends of the connecting rod 33 are detachably connected to the first connecting plate 31 and the second connecting plate 32, respectively. In this embodiment, the detachable connection is a threaded connection; in other embodiments, it can also be set as a magnetic connection, snap-fit ​​connection, or pin connection, or other similar connection methods. Furthermore, a limiting plate 5 is also provided on one side of the base 11. By setting the limiting plate 5, the movement path of the base 11 is limited, further improving the detection accuracy and preventing differences in detection accuracy caused by the offset of the base 11. In specific implementation, the limiting plate 5 can be set as a chain. The design of the chain-shaped fiberboard can effectively improve the adaptability of the limiting plate 5, making it suitable for welded pipes 4 of different diameters. Furthermore, the two ends of the chain-shaped limiting plate 5 can be designed as detachable connections for easy installation and fixation.

[0028] In use, the phased array ultrasonic testing system described in this application is placed on both sides of the weld (not shown in the figure), with the two testing probes 25 aligned with both sides of the weld. The limiting plate 5 is installed on one side of the base 11 to limit its movement path. After installation, the testing probes 25 are activated, and the first connecting plate 31 and the second connecting plate 32 are pushed by hand at a uniform speed. Driven by the first connecting plate 31 and the second connecting plate 32, the two bases 11 move synchronously along the outer periphery of the welded pipe 4 for testing.

[0029] This application features a simple structure, low manufacturing cost, and strong adaptability. Specifically, the base 11 design provides stable support for the detection probe 25 while allowing it to be directly adsorbed onto the surface of the welded tube 4 (or plate) and moved flexibly. This effectively avoids the instability in accuracy and operator fatigue caused by manual handheld detection, significantly reducing operational difficulty and technical barriers, and possesses significant market promotion value. Furthermore, this application is highly adaptable; as long as the outer diameter of the welded tube 4 is larger than the opening of the base 11, stable adsorption can be achieved, making it applicable to a wide range of situations.

[0030] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
