Description

Technical Field

[0001] This invention relates to the field of pile crack detection technology, and more specifically, to a device for detecting cracks in building piles. Background Technology

[0002] In construction engineering, pile structure inspection is frequently required, especially in bridge engineering. As critical load-bearing components, the piles supporting the bridge superstructure are of paramount importance in terms of structural health. Cracks on the pile surface are a common and potentially dangerous form of damage, potentially caused by factors such as load, environmental erosion, and material aging. Timely and accurate detection of these cracks is crucial for preventing major safety accidents. However, actual inspections often encounter several challenges, such as: 1. Pile structures are frequently located above water bodies, canyons, or busy traffic areas. Manual inspection (e.g., using scaffolding or suspended platforms) is not only extremely inefficient and costly but also poses significant safety risks, including falls from heights; 2. Different bridges, and even different piles within the same bridge, can have significantly different diameters. Existing automated or semi-automated inspection equipment (such as fixed-size crawling robots or inspection rings) is often only suitable for piles with a specific diameter range. When dealing with diameter variations, frequent fixture changes, structural adjustments, or the use of multiple sets of equipment are necessary, resulting in cumbersome operations that severely limit inspection efficiency and application scope, failing to meet the need for rapid and universal inspection of various types of piles. 3. Existing automated or semi-automated testing equipment has a complex structure and is not easy to store. Summary of the Invention

[0036] Example

[0037] Please refer to Figures 1-7 This embodiment provides a crack detection device for a building pile 3, including a moving component, a detection component, and an adjusting component. The moving component includes a traveling support 1 and multiple rotor mechanisms 2. The traveling support 1 can be fitted onto the pile 3 to be detected, and the multiple rotor mechanisms 2 are evenly spaced circumferentially on the traveling support 1. The adjusting component includes a movable ring 4, a base ring 5, and multiple linkage mechanisms evenly spaced circumferentially on the traveling support 1. Each linkage mechanism includes a first adjusting plate 6 and a connecting rod 7. The base ring 5 is disposed on the traveling support 1, and the movable ring 4 is coaxially disposed on the base ring 5, and the movable ring 4 can rotate freely circumferentially on the base ring 5. The first adjusting plate 6 has an arc-shaped structure. One end of the first adjusting plate 6 is rotatably disposed on the movable ring 4, and the other end is a free end. The openings of the multiple first adjusting plates 6 along the same circumference all have the same orientation. One end of the connecting rod 7 is hinged to the middle of the first adjusting plate 6, and the other end is hinged to the base ring 5. An adjusting opening 8 that can pass through the pile 3 is formed between the free ends of the multiple first adjusting plates 6. The detection component is mounted on the traveling support 1 and faces the pile body 3 being detected. The free end of any of the first adjusting plates 6 is provided with an auxiliary drive component 9 that can assist in movement on the pile body 3.

[0038] The aforementioned moving component drives the detection component and the adjusting component to perform lifting, lowering, and rotating actions. The detection component is used to detect cracks in the pile body 3. The adjusting component is used to adjust the diameter to fit the pile body 3. The traveling support 1 is used to install and support other components. The rotor mechanism 2 works in conjunction with each other to achieve the lifting, lowering, and rotating of the traveling support 1 and other components. The aforementioned adjusting component is actually an iris-shaped multi-link adjusting mechanism. By arranging multiple first adjusting plates 6 with their openings facing the same direction along the same circumference on the movable ring 4, and using the connecting rod 7 to drive the corresponding first adjusting plates 6 to rotate relative to each other on the movable ring 4, the multiple first adjusting plates 6 can rotate synchronously. During synchronous rotation, the free end of the first adjusting plate 6 will contract or expand along the diameter direction of the base ring 5, thus achieving adjustment of the diameter of the adjusting port 8.

[0039] Thus, after the first adjusting plate 6 rotates, the position of the auxiliary driving component 9 can be changed, and the diameter of the adjusting port 8 can be changed to adapt to piles 3 of different diameters. This allows the adjusting port 8 to adaptively detect piles 3 of different diameters, greatly improving detection efficiency and convenience.

[0040] Specifically, the aforementioned rotor mechanism 2 is actually an existing structure that utilizes multiple rotors to generate power for lifting and lowering. Simultaneously, it utilizes the speed difference between the rotors to achieve rotational motion. The rotor mechanism 2 is an existing structure on existing rotary-wing UAVs and will not be further described here. If anything is unclear, please refer to existing technology. It is worth noting that in this embodiment, the walking support 1 is equipped with components such as a power supply that are compatible with the rotor mechanism 2.

[0041] It should be noted that in this embodiment, the components such as the movable ring 4 and the base ring 5 that need to be fitted onto the pile body 3 are two detachable semi-circular ring structures (not shown in the figure). Therefore, in the initial stage of testing, the components such as the movable ring 4 and the base ring 5 that need to be fitted onto the pile body 3 can be fitted onto the pile body 3 by splicing, and can be disassembled after the testing is completed. Specifically, a detachable part is provided between the semi-circular ring structures to achieve disassembly and assembly. The detachable part includes lugs (not shown in the figure) provided on the two semi-circular ring structures and located at the splice point. The two corresponding lugs are fixedly connected by bolts.

[0042] Please refer to Figures 1-7 In some embodiments of this example, a second adjusting plate 10 is provided at one end of the first adjusting plate 6, which is away from the free end of the first adjusting plate 6. One end of the second adjusting plate 10 is connected to the first adjusting plate 6, and the other end is a free end. Multiple rotor mechanisms 2 are correspondingly arranged at the free ends of multiple second adjusting plates 10. The second adjusting plate 10 is used to adjust the position of the rotor mechanism 2. It rotates with the first adjusting plate 6. Thus, when the first adjusting plate 6 rotates and the adjusting opening 8 becomes smaller, the actual distance between the rotor mechanism 2 and the pile body 3 will increase, which means that the diameter of the pile body 3 is smaller. Appropriately increasing the distance between the rotor mechanism 2 and the pile body 3 can improve the stability of lifting and rotating actions.

[0043] Conversely, if the adjustment port 8 is enlarged, the actual distance between the rotor mechanism 2 and the pile 3 will be appropriately reduced, which means that the diameter of the pile 3 is larger. Appropriately reducing the distance between the rotor mechanism 2 and the pile 3 can also improve the stability of lifting and rotating actions.

[0044] Furthermore, the aforementioned rotor mechanism 2 can move with the second adjusting plate 10, and can also be folded up for easy storage and transportation.

[0045] Please refer to Figures 1-7Furthermore, in this embodiment, the second adjusting plate 10 has an arc-shaped structure, and the arc-shaped opening direction of the second adjusting plate 10 is opposite to the arc-shaped opening direction of the first adjusting plate 6. The fact that the arc-shaped opening directions of the second adjusting plate 10 and the first adjusting plate 6 are opposite ensures that when the first adjusting plate 6 is rotated to the maximum position of the adjusting port 8, the rotor mechanism 2 can still operate effectively, preventing interference between the rotor mechanisms 2.

[0046] Please refer to Figures 1-3 In some embodiments of this example, the aforementioned traveling support 1 is a cylindrical structure, with adjustment components at both ends. Each of the aforementioned movable rings 4 is equipped with a drive mechanism for rotating it. The cylindrical structure of the traveling support 1 allows the adjustment components at both ends to contact the pile body 3 via auxiliary drive components 9, thereby improving the stability of rotation and lifting movements. The aforementioned drive mechanism is used to drive the corresponding movable ring 4 to rotate.

[0047] Please refer to Figures 1-3 Preferably, in this embodiment, the aforementioned driving mechanism includes a drive motor 11, a drive gear 12, and an external gear ring 13. The drive motor 11 is mounted on the traveling bracket 1, the drive gear 12 is sleeved on the rotating output shaft of the drive motor 11, and the external gear ring 13 is circumferentially disposed on the outer side wall of the movable ring 4 and integrally formed with the movable ring 4. The external gear ring 13 meshes with the drive gear 12. The drive motor 11 drives the drive gear 12 to rotate. After the drive gear 12 rotates, it can drive the external gear ring 13 meshing with it to rotate, thereby driving the movable ring 4 integrally formed with the external gear ring 13 to rotate. After the movable ring 4 rotates, the corresponding first adjusting plate 6 and connecting rod 7 can be activated to realize the adjustment of the adjusting port 8.

[0048] Please refer to Figures 1-3 Preferably, the drive motor 11 is a dual-axis motor, and the two rotating output shafts of the drive motor 11 are respectively used to mount two drive gears 12. Since the walking mechanism in this embodiment adopts a cylindrical structure with adjustment components at both ends, the adjustment components at both ends need to be driven synchronously to ensure the stability of the adjustment. Specifically, the movable rings 4 in the adjustment components at both ends each require corresponding drive mechanisms; therefore, it is sufficient to use two drive mechanisms sharing the same drive motor 11. The drive motor 11 is a dual-axis motor, and the two rotating output shafts of the dual-axis motor are respectively mounted on two drive gears 12, thus enabling synchronous driving of the two adjustment components.

[0049] Please refer to Figure 7It is worth noting that in this embodiment, at least one arc-shaped travel groove 14 is provided on the base ring 5, and a sliding member 15 is provided in the travel groove 14. The sliding member 15 is connected to the movable ring 4. In this way, the rotation travel of the movable ring 4 can be limited, so as to control the size of the adjustment port 8.

[0050] Furthermore, in this embodiment, the aforementioned drive motor 11 is actually a self-locking motor. After the motor stops working, the motor's rotational output shaft automatically locks, thus locking the corresponding drive gear 12 and stopping the corresponding movable ring 4 from rotating. After the movable ring 4 is locked, the first adjusting plate 6 is also locked, ensuring that the auxiliary drive component 9 on the first adjusting plate 6 can effectively contact the pile body 3 during lifting, rotating, and other movements.

[0051] Please refer to Figure 8 In some embodiments of this example, the auxiliary driving component 9 includes a ball bearing 902 and a ball bearing sleeve 901. The ball bearing sleeve 901 is disposed at the free end of the first adjusting plate 6, and the ball bearing 902 is disposed in the ball bearing sleeve 901 and can roll freely on the pile body 3. Since the ball bearing 902 can roll freely within the ball bearing sleeve 901, regardless of how the first adjusting plate 6 moves, it can be ensured that the ball bearing 902 can roll normally on the pile body 3 after contacting it, thus assisting in movement.

[0052] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
