as shown in fig. 1 and 2, the elevator with self-adjusting variable-pressure counterweight is similar to a conventional elevator in structure, and comprises a hoistway 1, a car 2, a traction mechanism 3 and a counterweight 4, wherein an opening communicated with each floor is designed in the hoistway 1, and an electric door controlled by a main control circuit is designed in the car 2. In this embodiment, the traction mechanism 3 is mounted on the upper portion of the hoistway 1, the traction mechanism 3 is connected to the upper portions of the car 2 and the counterweight 4 through a steel cable 31, and the counterweight is mounted on the rear portion of the car. In this patent elevator still the vertical gas circuit that is equipped with the pipe shape in the well 1 is responsible for 5, the inside processing that the gas circuit was responsible for 5 is the smooth surface, balancing weight 4 is the cylinder shape, balancing weight 4 sliding seal assembles inside the gas circuit is responsible for 5, the gas circuit is responsible for 5 upper portions and opens the lower part and seals, the gas circuit is responsible for the lower part of 5 and is equipped with main release valve 51. The balancing weight 4 and the lower part of the air path main pipe 5 form a closed structure.
This transformation counter weight is when self-interacting elevator uses, if the people or the goods overweight of loading in the car 2, the gas circuit is responsible for 5 main disappointing valve 51 and closes, the gas circuit is responsible for 5 lower parts and is formed airtight chamber, works as during car 2 downstream, the gas circuit is responsible for 5 lower parts airtight chamber atmospheric pressure and is reduced and form the negative pressure, at this moment balancing weight 4 receives downward gas pressure, makes balancing weight 4 applys bigger traction force to its cable wire 41 of being connected, will make like this traction mechanism 3 is right the traction force that car 2 applyed reduces greatly, power when can greatly reduced car 2 moves. When the car 2 moves upwards, because the pressure in the air path main pipe 5 is negative pressure, the counterweight block 4 is also under the action of downward gravity and air pressure, so that the steel cable 31 connected with the counterweight block 4 is under a larger pulling force, and the traction force applied to the car by the traction mechanism 3 is greatly reduced.
