A safety chain protection system for a climbing-free device of a wind turbine comprises a climbing-free device safety detection unit and a lifting control circuit unit. The climbing-free device safety detection unit is provided with three safety detection loops including an anti-falling sliding block detection loop, a traction rope detection loop and a load detection loop. An output module of the climbing-free device safety detection unit adopts relay output, and a relay switch is connected to an external input circuit of a main control unit in the lifting control circuit unit and serves as an input signal of the main control unit; a sliding block installation detection device, a steel wire rope abrasion detection device and a pressure detection device safety chain control protection loop are designed, double sliding block detection is conducted, static and dynamic detection is conducted on the steel wire rope, and the overall safety performance of the climbing-free device is improved.
