It provides a stable three-dimensional support foundation through a multi-frame fixed bracket, and combines this with a flexibly adjustable fixing component to fix and adjust the sensor's position and orientation. The first support frame serves as the main support surface, while the symmetrical and non-coplanar second support frames on both sides greatly enhance the rigidity of the overall structure and expand the sensor placement space, enabling it to cover a wider detection area.

This design allows the operator to freely combine and adjust the position and orientation of multiple sensors according to the specific shape of the workpiece being inspected and the requirements of the detection path, achieving precise positioning of a single sensor and coordinated layout among multiple sensors, significantly improving the flexibility and adaptability of the detection.

Description

Technical Field

[0001] This utility model relates to a sensor support mechanism for integrity detection, belonging to the technical field of detection equipment. Background Technology

[0002] Integrity testing is a crucial part of modern manufacturing, and non-destructive testing technologies such as ultrasonic and eddy current testing are key means to ensure the safety and reliability of these structures. However, when performing scanning inspections on large, complex curved structures, how to stably, flexibly, and accurately fix and arrange multiple sensors (probes) has always been a technical challenge.

[0003] Traditional sensor mounting methods often employ manual pasting, magnetic attachment, or simple rigid clamps. While manual pasting offers flexibility, it's difficult to guarantee consistent and repeatable sensor orientation (angle and position), and post-pasting adjustments are extremely inconvenient, severely impacting the comparability and accuracy of detection data. Magnetic attachment is only suitable for ferromagnetic materials, limiting its application range, and its adhesion stability on curved surfaces is insufficient, making it prone to shifting during scanning. Simple rigid clamps, while stable, lack sufficient adjustment freedom, making them unsuitable for complex curved surfaces and different detection process requirements. This can lead to poor coupling between the sensor and the surface being detected, resulting in detection blind zones or a decreased signal-to-noise ratio.

[0004] Furthermore, existing support mechanisms are often designed for specific workpieces or specific detection paths, lacking versatility. When the detection area needs to be changed or the sensor array layout needs to be adjusted, the entire support mechanism may need to be redesigned and manufactured, which is time-consuming, labor-intensive, and costly. Especially when multi-sensor collaborative detection of different areas and angles of a large component is required, there is a lack of a universal support platform that can integrate multiple sensors and allow for rapid and independent adjustment of their spatial pose.

[0005] Therefore, there is an urgent need in this field for a new type of sensor support mechanism that can solve the above problems and enable flexible, stable and repeatable precise positioning of the sensor in three-dimensional space, so as to meet the urgent needs of modern industry for efficient and high-precision integrity detection of large and complex structures.

[0023] Please refer to Figures 1 to 2 An embodiment of this application shows a sensor support mechanism for integrity detection, which includes a base 10, a fixed bracket 20, and a fixing assembly. A support platform is formed on the base 10, and a fixing plate 11 is arranged at the bottom of the base 10. The fixing plate 11 has mounting holes for installing fixing bolts.

[0024] The fixed bracket 20 includes a first support frame 11 and a second support frame 12 arranged in a vertical direction. The second support frame 12 is provided in two sets and is symmetrically arranged on both sides of the first support frame 11. The plane of the second support frame 12 does not coincide with the plane of the first support frame 11.

[0025] The fixing assembly is arranged on the fixing bracket 20. The fixing assembly includes a support frame fixed on the fixing bracket 20 and a plurality of sensor fixing structures 15 distributed on the support frame. The plurality of sensor fixing structures 15 are configured to move on the support frame to cooperate with adjacent sensor fixing structures 15 to fix the sensor and adjust the fixed position of the sensor.

[0026] In one embodiment, the support frame includes at least two sets of fixed rods 13 arranged horizontally at the upper and lower ends of the fixed bracket 20, and connecting rods 14 connecting the at least two sets of fixed rods 13. The sensor fixing structure 15 is arranged on the connecting rods 14. The support frame adopts a grid structure composed of fixed rods 13 and connecting rods 14. The fixed rods 13 are responsible for reliable connection with the fixed bracket 20, while the connecting rods 14 form multiple parallel tracks in the vertical direction. This design not only simplifies the structure and reduces weight, but more importantly, it provides a clear and orderly movement path for the sensor fixing structure 15. The sensor can be linearly positioned along the length of the connecting rods 14, making the deployment process more regular and efficient, and facilitating the equal-spaced or regularly non-equal-spaced arrangement of the sensor array.

[0027] In one embodiment, the sensor fixing structure includes a connecting seat 151 fixedly connected to the connecting rod 14 and a fixing seat 152 rotatably connected to the connecting seat. The connecting seat 151 includes a pair of symmetrically clamping members on the connecting rod and a locking bolt connecting the pair of clamping members. The locking bolt and the fixing seat 152 are respectively arranged on both sides of the connecting rod. The connecting seat 151 of the sensor fixing structure 15 adopts a bolt locking mechanism. Under the preload of the locking bolt of the pair of clamping members, the connecting rod 14 is naturally clamped, so that the sensor fixing structure 15 can be temporarily held in a certain position for easy initial positioning. A connecting hole is formed on the fixing seat 152. The other end of the clamping member is rotatably connected to the connecting hole of the fixing seat 152. Under the action of the preload, the end of the clamping member opens the connecting hole to both sides, thereby achieving the fixing effect of the fixing seat 152. Therefore, reducing the preload makes it easier to adjust the angle of the fixing seat 152, and increasing the preload makes it easier to lock the position of the fixing seat 152.

[0028] In one embodiment, the retaining member is provided with a retaining groove, and the fixing seat 152 is retained in the retaining groove. The fixing seat 152 is connected to the connecting seat 151 through the retaining groove, which is a design for quick installation and removal. The operator can easily remove or install the fixing seat 152 from the connecting seat 151, which facilitates the replacement and maintenance of the sensor or the quick switching of sensor configuration for different detection tasks, greatly improving the ease of use.

[0029] In one embodiment, the mounting base 152 is a U-shaped mounting plate 11, with a mounting opening 1521 for holding the sensor on its bottom. Several mounting holes 1522 for fixing the sensor are provided on the sidewalls of the U-shaped mounting plate 11. The design of the U-shaped mounting plate 11 forms a semi-enclosed structure, providing good protection and support for the sensor. The mounting opening 1521 at the bottom facilitates the passage of the sensor cable and the suspension installation of the sensor. The multiple mounting holes 1522 on the sidewalls mean that the sensor's vertical position can be finely adjusted on the U-shaped mounting plate 11, and the pitch angle of the sensor can be precisely adjusted by selecting different mounting holes 1522 or adding shims, thereby perfectly adapting to detection surfaces with different curvatures and ensuring optimal acoustic or electromagnetic coupling.

[0030] In one embodiment, at least two sets of sensor fixing structures 15 are arranged on each connecting rod 14. This makes the mechanism particularly suitable for detection scenarios requiring high-density sensor arrays, such as fine scanning of critical areas or the use of phased array technology, where a large number of sensors can be integrated in a limited space, improving detection efficiency and resolution.

[0031] In one embodiment, a pair of second support frames 12 extend obliquely from both sides of the first support frame 11 toward the front end face of the first support frame 11. This oblique extension of the second support frames 12 results in the entire fixed bracket 20 having a spatially larger "basket" or "figure-eight" shaped structure with a larger front opening. This structure is not only more mechanically stable, but more importantly, it greatly expands the sensor's coverage area in front and to the sides, making it particularly suitable for detecting complex curved surfaces with a certain angle or protrusion, and avoiding interference from the support frame itself on the sensor's movement path.

[0032] In one embodiment, both the first support frame 11 and the second support frame 12 include a contour frame and at least one set of reinforcing rods arranged horizontally within the contour frame. Fixed rods 13 are arranged at the ends of the contour frame and on the reinforcing rods. The contour frame forms the basic shape of the support, while the horizontally arranged reinforcing rods significantly enhance the frame's resistance to bending and torsional deformation, ensuring that the entire support maintains extremely high rigidity even after suspending multiple sensors. Arranging the fixed rods 13 at the ends of the contour frame and on the reinforcing rods effectively provides sensor mounting points at multiple height levels of the support, enabling multi-layer sensor deployment in the vertical direction and further enhancing the spatial layout capability and versatility of the support mechanism.

[0033] This application provides a stable three-dimensional support foundation through a fixed bracket composed of multiple frames, and combines it with a flexibly adjustable fixing component to fix and adjust the position and orientation of the sensor. The first support frame serves as the main support surface, while the two symmetrical and non-coplanar second support frames greatly enhance the rigidity of the overall structure and expand the sensor placement space, enabling it to cover a wider detection area. The sensor fixing structure in the fixing component can move on the support frame. This design allows the operator to freely combine and adjust the position and orientation of multiple sensors according to the specific shape of the workpiece being inspected and the requirements of the detection path, achieving precise positioning of a single sensor and collaborative layout among multiple sensors, significantly improving the flexibility and adaptability of the detection.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
