The invention discloses an automatic lifting device and method for a tower-shaped mast. A mast base frame is provided with a horizontal shaft, and the lower portion of the mast is hinged to the horizontal shaft. A mast motor on the mast is meshed with a speed reduction gear through a driving gear and an intermediate gear. The mast base frame is provided with a fixing gear coaxial with the horizontal shaft. The speed reduction gear is meshed with the fixing gear. A balance block is arranged at the position, below the horizontal shaft, of the tail end of the mast. Swinging type barrier detection devices are arranged on two sides of the top of the mast respectively. The automatic lifting device for the tower-shaped mast further comprises a control device and an alarm device. The control device is connected with the mast motor, the barrier detection device and the alarm device. The automatic lifting device and method for the tower-shaped mast resolve the problem that mast in the prior art are prone to being crashed due to negligence or misjudgment.
