Earthquake, strong wind and perpendicularity early warning device for tower crane and using method thereof

The invention discloses a tower crane earthquake and strong wind prevention and perpendicularity early warning device and a using method thereof, and particularly relates to the technical field of safety early warning of constructional engineering, the tower crane earthquake and strong wind prevention and perpendicularity early warning device comprises a tower crane cab power supply, the positive electrode wiring end of the tower crane cab power supply is connected with an audible and visual alarm, and an early warning assembly is installed at the bottom end of the audible and visual alarm. The early warning assembly is adopted, when a straight copper wire above the tower crane shakes, the audible and visual alarm supplies power to give an alarm, the audible and visual alarm supplies power, a driver who needs to go to the tower crane can clearly observe the perpendicularity at the bottom of the tower crane, and therefore the perpendicularity of the tower crane can be clearly observed in the gale weather and t
