The invention relates to the technical field of winch equipment for petroleum drilling, in particular to a petroleum winch double-stop safety redundancy protection system which comprises a first protection system, a second protection system and a main air inlet pipe, the first protection system comprises an overwinding anti-collision valve arranged on the upper portion of the roller, a low-position anti-collision valve arranged on the lower portion of the roller and a first air inlet pipe, the first air inlet pipe is sequentially connected with the overwinding anti-collision valve and the low-position anti-collision valve, connected end to end and connected with the main air inlet pipe, and the second protection system comprises a mechanical control valve box and a second air inlet pipe. According to the anti-collision device, the mode of combining electronic anti-collision and double-mechanical anti-collision is adopted, and triple safety protection of upper collision and lower smashing is achieved. According to the system, the situation that the safety protection system fails due to partial mechanical or electronic faults is effectively avoided, the safety redundancy is improved, and the stability and reliability of the safety protection system are ensured.
