Safety protection device capable of crossing obstacles without unfastening main waist rope and method thereof

The invention discloses a safety protection device and method for crossing obstacles without unfastening a main waist rope, and the device comprises a pay-off unit which comprises an anti-return assembly, a positioning assembly disposed at one side of the anti-return assembly, a locking assembly disposed at one side of the positioning assembly, and a clamping assembly disposed at the bottom of the locking assembly. The limiting assembly is arranged on one side of the clamping assembly; the hanging unit comprises a fixed hanging assembly and a protection assembly arranged at the bottom of the fixed hanging assembly. The device has the beneficial effects that the steel wire rope is quickly paid off by pulling the anti-return assembly, the friction force is increased during rotation of the anti-return assembly to prevent the steel wire rope from quickly falling off, the rotary positioning assembly moves downwards to extrude and position the steel wire rope, the stability is enhanced, and the distribution line ne
