Pneumatic elevator and control method

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...

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 the mechanical parts after a long period of operation. When the mechanical parts When the mechanical failure occurs due to wear and tear, there may be an incident of falling down the ladder, which is prone to danger

Existing elevators generally use brakes to prevent falling events. When an accident occurs in the elevator, the brakes will be locked to prevent the elevator from falling. When the brake locks suddenly, it may cause injury to the people in the elevator first, and may cause damage to the elevator guide rail and other components at the same time.
