The invention discloses an automatic lifting device and method of a cylindrical mast. A horizontal rotating shaft is arranged on a mast base frame. A sliding sleeve is fixed to the middle of the horizontal rotating shaft. The mast penetrates in the sliding sleeve. The outer wall of the lower half part of the mast is axially provided with a rack. A mast motor is engaged with the rack through a mast drive gear and a mast lifting gear. The mast base frame is provided with a fixing gear coaxial with the horizontal rotating shaft. The mast lifting gear is engaged with the fixing gear through a reduction gear set. Swinging type obstacle detecting devices are arranged on the two sides of the top of the mast. The automatic lifting device of the cylindrical mast further comprises a control device and an alarm device. The control device is connected with the mast motor, the obstacle detection devices and the alarm device. The automatic lifting device and method effectively solve the problem that a mast lifting device in the prior art is likely to cause collision accidents due to negligence or misjudgment. The automatic lifting device of the cylindrical mast can automatically detect an obstacle and automatically place the mast down, the navigation safety is ensured, and high practical value is achieved.
