Multi-layer vacuum pneumatic elevator

Abstract

The invention relates to a multi-layer vacuum pneumatic elevator which comprises a well, a guide rail arranged in the well, car arranged in the well and capable of sliding up and down along the guide rail, and a vacuum inspiration device arranged on the top of the well, wherein a peripheral sealing ring is arranged on the top of the car; telescopic supporting rods are respectively arranged on parts, corresponding to the top of each floor, in the well; sealed partition plates are placed on the telescopic supporting rods; the well is divided into a plurality of sealed spaces by virtue of the partition plates and the peripheral sealing ring; and the vacuum inspiration device is communicated with the spaces by virtue of an air exhausting pipeline. The well is divided into a plurality of sealed spaces, so that when the elevator is driven to operate, air in a certain floor is only needed to be extracted to obtain enough up-down pressure difference for driving the elevator to operate, and therefore, the air exhausting efficiency is improved and the energy consumption is greatly lowered.

Description

technical field [0001] The invention relates to the field of pneumatic elevators, in particular to a multi-storey vacuum pneumatic elevator. Background technique [0002] At present, general-purpose elevators generally include components such as machine room, shaft, pit, car and landing, through traction system, guiding system, car system, door system, balance system, electric drive system, The protection system ensures the operation of the elevator. It occupies a large space, has high requirements for the shaft, and has high production, use and maintenance costs. The existing vacuum pneumatic elevator removes the machine room, shaft and pit of the ordinary elevator, and transmits power through the air, which has the advantages of small footprint, low use and maintenance costs, etc., but due to its special driving principle, it There is the problem that the air extraction efficiency of multi-level elevators is too low; when the air extraction space of the elevator is large,...
