A crack detection device for concrete utility poles
This invention belongs to the field of concrete pole testing technology, and specifically relates to a concrete pole crack detection device, including a mounting frame. Multiple supporting hydraulic cylinders are fixedly connected to the side wall of the mounting frame. The moving end of each supporting hydraulic cylinder passes through the mounting frame and is fixedly connected to a supporting plate, which has an arc-shaped structure. The concrete pole to be tested is placed on the multiple supporting plates. This invention employs a step-by-step method of water testing followed by negative pressure testing to inspect surface cracks in concrete poles. Water testing visually detects wide, continuous harmful cracks, while air pressure precisely captures minute, continuous harmful cracks. This layered inspection efficiently distinguishes between harmless surface scratches and continuous harmful cracks of different sizes, improving the accuracy of crack detection, avoiding the omission of small harmful cracks and mistaking scratches for defects, thus ensuring the reliability of pole crack detection results.
