Temporary bridge structure for offshore wind power engineering wind turbine maintenance

The invention discloses a temporary bridge structure for offshore wind power engineering wind turbine maintenance. The temporary bridge structure comprises a supporting flat plate, a first supportingframe is fixedly connected with one end of the supporting flat plate, an extending and retracting adjusting frame is connected below the supporting flat plate, and one end of a second supporting frameis located in the extending and retracting adjusting frame and can freely slide along the extending and retracting adjusting frame. According to the temporary bridge structure for offshore wind powerengineering wind turbine maintenance, installation and fixation are fast, the temporary bridge structure is convenient to pack up after being used; the temporary bridge structure is high in safety and reliability, high in applicability and capable of effectively dealing with the marine complex environment; the temporary bridge structure is light and practical, and is convenient to store and transfer during non-use time; ex
