The invention discloses an intelligent auxiliary lifting system for a power tower. The intelligent auxiliary lifting system comprises a system support structure (including a system horizontal support structure and an oblique support structure) (2), a system control and execution system (3), a system lifting structure (4), a load locking device (5) and an intelligent mobile phone (7). The system support structure (2) is fixed to the top of the power tower (1), the system control and execution system (3) is mounted on the support structures, and the intelligent mobile phone (7) is used by an operator and user (6) for controlling the intelligent auxiliary lifting system. The intelligent auxiliary lifting system has the advantages that the intelligent auxiliary lifting system is safe and reliable, can be intelligently controlled, is wide in adaptive environment range, is particularly applicable to operation scenes with requirements on climbing on and off large power towers, is in intelligent control modes, can be remotely controlled via the intelligent mobile phone and can be quickly automatically lifted when tower-related operation is carried out, and accordingly problems in the aspects of safety and efficiency due to current manual climbing can be solved.
