The invention discloses an elevator weighted by utilizing air pressure. The elevator mainly comprises an air pressure weight mechanism and a pulley block, wherein the air pressure weight mechanism comprises a pressure sensor arranged at the bottom of an elevator car, a circular drum, an air cylinder, a piston and an inflatable and exhaust device; the air cylinder is positioned in the circular drum; the piston is positioned at the bottom of the air cylinder; and the inflatable and exhaust device is connected with the piston. The pulley block is connected with the elevator car and the air cylinder. The pressure sensor generates corresponding electric signals and transmits the electric signals to a single chip microcomputer, and then an instruction is issued to the inflatable and exhaust device by the single chip microcomputer.
Description
technical field [0001] The invention relates to an elevator using air pressure counterweight, specifically, it is a kind of elevator that can change the volume of gas in the cylinder according to the change of the total weight of the elevator caused by the change of the number of people in the elevator, so that the pressure in the cylinder can be changed, and the external air pressure can be changed. A device that balances the weight of the elevator by creating a pressure difference with the air pressure in the cylinder. Background technique [0002] Traditional hydraulic elevators use liquid to flow into the cylinder to push the piston upwards to make the elevator car rise upwards. To make the elevator rise to the top, the pistons and cylinders are too long. Another disadvantage of traditional hydraulic elevators is efficiency. Low. It takes a lot of energy to raise an elevator several floors, and in a standard hydraulic elevator, there is simply no way to store this energ...
