A cable detection device

Abstract

This invention discloses a cable inspection device, including a base, two oppositely arranged bushings, and multiple inspection units between the two bushings. The two bushings are coaxially arranged, and each of the two opposite ends of the bushings is provided with multiple centering structures for ensuring that the cable passes coaxially through the bushings. The upper part of the base is connected to the two bushings via a driving device, which can move the two bushings closer or further apart and synchronize the operation of the multiple inspection units. This invention, through the centering structures, ensures that the cable passes coaxially through the two bushings. It allows adjustment of the inspection units according to different cable diameters. By setting multiple inspection units, it can simultaneously inspect the outer wall of the same cross-section of the cable, quickly identify abnormal parts of the cable, and enable inspection of cables of different specifications, thus improving the applicability of the inspection device.
