Potential energy lift

Abstract

The invention relates to the technical field of lifts and discloses a potential energy lift. The potential energy lift comprises a pulley, a steel wire rope, a lift car and a cylinder way in which the lift car is operated. The potential energy lift is characterized in that: the bottom of the lift car is in closed contact with the cylinder way; an opening is formed at the upper end of the cylinder way; four circumference walls and the bottom of the cylinder way are closed; and the bottom of the cylinder way is provided with an air vent hole, a one-way valve and a cylinder way door for one person to enter and exit. When the person takes the lift car to fall down from a high position, air in the cylinder way is compressed, the one-way valve is automatically closed, air is exhausted from the air vent hole, the lift car descends slowly under the action of air resistance to reach the bottom of the cylinder way, and the cylinder way door is automatically opened, so that the person can leave the cylinder way. According to the potential energy lift disclosed by the invention, the person is convenient to go downstairs, go down from a platform bridge or carry goods downward. The potential energy lift disclosed by the invention has the advantages of simple structure, safe operation and incapability of consuming energy resources, such as electric energy and the like.

Description

technical field [0001] The invention belongs to the technical field of elevators, and relates to a potential energy ladder descending by gravity. Background technique [0002] In modern society, people often have to go from a high space to a low space in their lives, such as going upstairs to downstairs at home, going up and down from a bridge to the ground, and many people in schools and shopping malls need to go downstairs frequently. At present, people generally take the elevator where there is an elevator, and take the stairs when there is no elevator; it is difficult for people to take the stairs when they are not feeling well and their legs and feet are inconvenient, and it is also dangerous for the elderly and children to take the stairs; It is also very difficult to go downstairs with large objects such as refrigerators and sofas, and it is even easy to damage items or cause injuries.

Problems solved by technology

At present, people generally take the elevator where there is an elevator, and take the stairs when there is no elevator; it is difficult for people to take the stairs when they are not feeling well and their legs and feet are inconvenient, and it is also dangerous for the elderly and children to take the stairs; It is also very difficult to go downstairs with large objects such as refrigerators and sofas, and it is even easy to damage items or cause injuries

It is a comfortable thing for people to take the elevator downstairs when there is an elevator, but because the elevator consumes a lot of power, and the price of the elevator is high enough to buy and maintain, it is expensive in many places.
