[0002] Cables are an important part of large-scale bridges. Cables are also key stress-bearing parts of bridges. One type of cable spans a relatively large length and height. Manual maintenance is not only time-consuming and laborious, but also has potential safety hazards. Therefore, there are A variety of cable automatic detection devices, Chinese Patent No. CN102323331B discloses an in-service cable defect detection device for detecting internal defects in cables. There are multiple detection modules in the circumferential direction, and the two ends of each detection module are respectively clamped together by the external frame set on the cable; the detection module is a modular design, consisting of a magnetized adsorption unit, an active unit, a driven unit and a detection probe unit ; The detection crawler moves along the cable by climbing on the surface to obtain the internal detection signal of the cable, and transmits it to the signal processing part for analysis and processing to complete the detection of the cable

This patent explains in detail how to detect the cable, but the device cannot repair the cable. Generally, if the PE protective tube outside the cable is slightly damaged, it is only necessary to wrap a heat shrinkable tape on its outer surface. It is cumbersome to erect a lifting device on the bridge through manual winding, and it will increase the workload of maintenance personnel and bring safety hazards to maintenance personnel
