The invention provides a rope winch winding drum for lifting off and retracting of an aerostat. The rope winch winding drum comprises a winding drum body (1), a friction ring (2) and a pair of annular stop shoulders (3). An annular friction groove is formed in the winding drum body (1). The friction ring (2) is installed in the annular friction groove in the winding drum body (1). The pair of annular stop shoulders (3) is installed on the two sides of the winding drum body (1) respectively through nuts. The rope winch winding drum for lifting off and retracting of the aerostat has the advantages that the rope winch winding drum is simple in structure and practical, the structural appearance of a conventional winding drum can be guaranteed, the traction performance of the conventional winding drum can be guaranteed, and installation, piece replacement and maintenance are convenient; the surface abrasion and load impact to a rope can be reduced in a large-load state, and the service life of the rope is prolonged.
