Description

BACKGROUND

Embodiments of the present disclosure relate to a pneumatic vacuum elevator and more particularly, to a system that stabilize and guide support of cabin movement with the pneumatic elevator.

Pneumatic vacuum elevators are typically used in countervailing weights in order to facilitate a cabin moving up and down between various layers or floors at various heights inside the vertical passageways of office buildings, hospitals, factories and similar structures. The pneumatic vacuum elevators use air pressure to cause the motion of the cabin within a thoroughfare or tubular cylinder that uses the air within it as a working fluid upon the confines of the cabin. Transmission of the pneumatic vacuum elevators are supported and guided by a mechanical device such as a guide rail. Generally, the guide rail is a part of an inner working mechanism of most of the pneumatic vacuum elevators and lift shafts. The guide rail is fixed on two sides of the shaft, wherein the one side of the guide rail guides the pneumatic vacuum elevator and the other side for the counterweight. In tandem, the guide rail operates both as stabilization within the shaft during routine use and as a safety system in case of emergency stops. Various types of guide rails are available which enables smooth ride of the cabin inside the vertical passageways.

Conventionally, the guide rail available in market for transmission of the cabin of the pneumatic vacuum elevator includes one or more wheels coupled to the cabin for ascending and descending motion of the elevator. However, such conventional system with the one or more wheels causes vibration which creates anxiety for the users. Furthermore, such conventional guide rail mechanism generates friction and noise during up and down motion of the pneumatic vacuum elevator.

Hence, there is a need for an improved guide rail-pillar system of pneumatic vacuum elevator and a method to operate the same in order to address the aforementioned issues.
