Lifting mechanical three-dimensional parking equipment adopting multi-head screw frame

The invention discloses lifting mechanical three-dimensional parking equipment adopting a multi-head screw frame. When a first layer of vehicles are taken, the vehicles are directly driven without starting a motor; when a second layer of vehicles are taken, the first of layers of vehicles are required to be driven away and then a button for a second layer of plots; a reducing motor works to drive a screw to rotate, the screw drives the screw frame to work, and the screw frame drives a vehicle carrying board to descend; when the vehicle carrying board descends to the lowest position, a limit switch automatically powers off and stops, and the vehicles can be driven away; when the vehicles are parked, the vehicles are driven on the vehicle carrying board, the reducing motor is started, and the screw and the screw frame work to drive the vehicle carrying board to ascend; and the vehicle carrying board ascends to the highest position, the limit switch automatically powers off and stops.
