The invention relates to an automatic power cable reel treatment detection rack. The detection rack comprises a supporting bottom plate, a bearing mechanism and a detection device. The bearing mechanism is mounted in the middle portion of the supporting bottom plate. The detection device is mounted on the top of the rear side of the supporting bottom plate. The detection device comprises a detection vertical plate, a detection electric sliding block, a detection adjustment mechanism, a detection mechanism, a scraping electric sliding block, a scraping mechanism and cutting mechanisms. Throughthe automatic power cable reel treatment detection rack, the problems that protrusions of a cable reel cannot be automatically detected, detection dead angles can occur during detection, the protrusions need to be hammered manually, wood splinters of the cable reel need to be scraped away manually and scratched wood splinters need to be cut off manually in the process of detecting the cable reel can be solved, and the automatic power cable reel treatment detection rack can achieve the protrusion detection and wood splinter scraping functions on a reel shaft board of the cable reel.
