Problems solved by technology

With the development of high-rise buildings, devices for transporting people or goods are also widely used. Common lifting devices in the prior art include escalators, elevators, etc., because escalators take up a lot of space and need to pass through when taking an escalator. Multiple transfers, therefore, the use of escalators is greatly restricted
At present, the most widely used is the elevator. The elevator is mainly composed of a car, a balance system, a traction system and a guiding system. The elevator with this structure will inevitably wear out t

Example Embodiment

[0042] Example 1

[0043] Such as figure 1 As shown, the pneumatic elevator in this embodiment includes an elevator hoistway with more than two floors, an elevator car 2 that runs up and down in the elevator hoistway, and a control device. The elevator hoistway 1 includes an integrated hoistway 101 and a buffer hoistway 102 The buffer hoistway 102 is a sealed hoistway located at the lower end of the lifting hoistway 101; wherein, the upper end of the lifting hoistway 101 is provided with a vent, and the lower end of the lifting hoistway 101 is provided with a vent and a gas inlet 103. The gas port and the gas charging port 103 are connected with a gas filling device and a gas releasing device; each hoistway is equipped with an air-tight elevator door;

[0044] At least the bottom of the elevator car 2 is provided with a sealing section that cooperates with the elevator hoistway 1 airtight (here the airtight is relatively sealed, and gas leakage is allowed under the condition of ens...

Abstract

The invention discloses a pneumatic elevator which is provided for mainly solving the problem that danger is prone to occurring when existing elevators drop. The pneumatic elevator comprises an elevator shaft, an elevator car and a control device. The elevator shaft comprises a lifting shaft body and a buffer shaft body. The buffer shaft body is arranged at the lower end of the lifting shaft body and connected with the lifting shaft body. The lower end of the lifting shaft body is connected with an air inflation device and an air deflation device. The bottom of the elevator car is matched with the elevator shaft in a sealed mode. The space which is located under the bottom of the elevator car in the elevator shaft is an airtight space. When the air inflation device charges air into the airtight space, the elevator car ascends. When the air deflation device deflates the airtight space, the elevator car descends. The control device is used for controlling starting and stopping of the elevator car. By adopting the pneumatic elevator, when the elevator drops, the elevator car cannot collide with other structures rigidly, and the safety coefficient is high.

Description

technical field [0001] The invention relates to a lifting device for transporting people or goods in a building, in particular to a pneumatic lift and a control method. Background technique [0002] As land resources become more and more scarce, the current architectural planning is planned as a high-rise structure. This kind of high-rise structure can maximize the use of limited land resources, and can also use existing resources to create maximum value. With the development of high-rise buildings, devices for transporting people or goods are also widely used. Common lifting devices in the prior art include escalators, elevators, etc., because escalators take up a lot of space and need to pass through when taking an escalator. Multiple transfers, therefore, the use of escalators is greatly restricted. At present, the most widely used is the elevator. The elevator is mainly composed of a car, a balance system, a traction system and a guiding system. The elevator with this s...
