Bending-resistance-force-change-based steel-cored aluminum strand breakage detector

The invention discloses an aluminum cable steel reinforced strand breakage detector based on bending strength change, which comprises a base placed above the ground, two first brackets are fixedly mounted on the upper surface of the base, and a winding roller is rotatably connected between the two first brackets; the two second supports are fixedly installed on the upper surface of the base, and a controller is fixedly installed on the front sides of the second supports; the detection cylinder is movably connected between the two second supports, and limiting pieces are fixedly installed at the two ends of the detection cylinder through fixing frames; the fixing plate is arranged on the outer side of the detection cylinder, and two fixing rings are fixedly mounted on the lower surface of the fixing plate; and the air storage bag is arranged on the inner side of the fixed cylinder. The steel-cored aluminum strand broken strand detector based on the bending resistance force change can continuously perform multi
