The utility model relates to the technical field of fireproof plugging, and particularly discloses a fireproof plugging device for a cable hole of a tower drum platform, which is characterized by comprising a plugging plug. The device has the advantages that the device is simple in structure and easy to implement; according to the utility model, the plugging plug is arranged at the position of the cable hole of the tower barrel platform, so that the fire behavior can be controlled to the greatest extent, and meanwhile, the sealing performance is good, and the fire behavior can be prevented from occurring and spreading; fireproof mud can be filled into the annular filling groove of the plugging plug, the use amount of the fireproof mud can be controlled to a certain extent, and extra loss cost is reduced; and meanwhile, the flame-retardant rubber layer in the through hole of the plugging plug can be removed layer by layer according to requirements, the sealing performance and the corrosion resistance of the pi
