Abstract
The invention relates to a pneumatic lift. The pneumatic lift comprises a shaft way, a lift car and a vacuum motor. A lift car seal ring is arranged on the top of the lift car. A top layer seal ring is arranged on the top of the shaft way. The lift car seal ring, the top layer seal ring and the side wall of the shaft way form a sealed space. The vacuum motor extracts or discharges air in the sealed space and drives the lift car of the pneumatic lift to move up and down. The overlooking outline of the shaft way is not a perfect circle. The outer outline of the lift car is matched with the shape of the shaft way. The lift car is limited in the shaft way. According to the pneumatic lift, the lift car is limited and guided through the shape of the shaft way, the lift car is prevented from rotating, the influence of a protruding guide rail on a seal effect is avoided, and the problem that noise is generated by air flow due to a poor seal effect is solved.
Description
Technical field
The present invention relates to elevators field, particularly relate to a kind of pneumatic elevator.
Background technology
Pneumatic elevator, as a kind of novel elevator technology, due to its counterweightless, without pit be easy to the features such as installation, becomes the hot spot technology of elevator industry already.At present, the structure of pneumatic elevator as depicted in figs. 1 and 2, mainly comprise: circular hoistway 1, guide rail 2, car 3 and vacuum motor, car seal ring 4 forms confined space with the sidewall of top layer seal ring 5 and hoistway 1, vacuum motor is utilized to bleed, pressure in described confined space is reduced, be communicated with external atmosphere pressure by bottom inflow hole 6 bottom car 3, vacuum motor so just can be utilized to form pressure difference to the top, sedan-chair top of car 3 and sedan-chair bottom, utilize the effect of this pressure difference that car 3 is promoted along described guide rail 2; Decline stage, car 3 self gravitation is relied on to carry out decline transport along guide rail 2, energy-conserving and environment-protective.
Please emphasis with reference to figure 2, existing hoistway 1 is disposed radially some projections and just defines guide rail 2, prevents car 3 from rotating in hoistway 1.Because the lifting power of the car 3 of pneumatic elevator is provided by gas pressure difference, so hoistway 1 just seems extremely important with the sealing of car seal ring 4 cooperation place.And guide rail 2 and car seal ring 4 are Dynamic link library (namely needing relative motion occurs), therefore sealing property is herein very weak, can cause a large amount of Leakage Gas, the consequence caused like this is exactly the power needing to increase vacuum motor, causes the waste of the energy; Another serious consequence is exactly that the place that contacts with car seal ring 4 of guide rail 2 is very near with the passenger's distance in car 3 all the time, and the noise that the leakage of such air-flow produces can bring strong human discomfort to passenger.
Summary of the invention
