The invention discloses a cylindrical mast lifting device and method. A mast base frame is provided with a horizontal rotating shaft. A sliding sleeve is fixed to the middle portion of the horizontal rotating shaft. A mast penetrates through the sliding sleeve. The outer wall of the lower half part of the mast is axially provided with a rack. A mast motor is meshed with the rack through a mast driving 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 meshed with the fixing gear through a speed reducing gear set. A swinging type obstacle detecting device is arranged on the top of the mast. The cylindrical mast lifting device further comprises a control device and an alarm device. The control device is connected with the mast motor, the obstacle detecting device and the alarm device. The cylindrical mast lifting device and method effectively solve the problem that a mast lifting device in the prior art causes collision accidents easily due to negligence or misjudgment. The cylindrical mast lifting device can automatically detect an obstacle and put down a mast, the navigation safety is ensured, and very high practical value is achieved.
