Description

Description of the invention

The utility model relates to pneumatic lifts, in particular elevators used in residential 2 buildings and other structures.

It is well known that the nearest analogue of the useful model is the pneumatic elevator developed by the American company "Uoyaope Eimayog from the state of Florida, described in the information "News of science and technology. A vacuum elevator with noise sucks in passengers", published on the Internet sites per//rg.Ka/apisiev, m/mlu.tetgapa.gy. 70 A vacuum pneumatic elevator is a transparent "bubble" that can raise and lower passengers without any cables, pulleys or hydraulic cylinders.Designed for installation in small buildings, it can have different lengths and two or three stops: upper and lower floors, and an exit at an "intermediate station". The elevator contains a circular transparent shaft made of polycarbonate with an external 94 centimeters in diameter, in which the cabin walks. The roof of the cabin is a piston fitted to the walls of the shaft, made mainly of aluminum 72 alloy. The doors in the shaft are hermetically sealed, and the cabin itself is ventilated from below. When a compact air vacuum pump installed at the top of the shaft , sucks air from the area above the cabin - it goes up, because the cabin itself, as well as in the mine below it, has normal atmospheric pressure (even at the bottom of the mine, there are windows in the floor for air passage). it is necessary to go down - the valve of the pneumatic system at the top of the mine gradually admits air into the rarefaction zone, smoothly regulating the speed of descent. No energy is needed for descent.

The speed of movement is 9.14 meters per minute, and the load capacity is 204 kilograms (two people can fit in the cabin). Doors on different floors can open both in one and the other direction, for example, on the first floor - to the south, and on the second - to the north. During entry and exit, the cab is fixed by additional mechanical stoppers. The main advantage of such an elevator is minimal remodeling of the building for its installation.

There is no need to dig a hole under the mine and arrange a special compartment in the attic. It is only necessary to drill a round hole in the floor, and in cases where the mine is located on the side of the house, this is not necessary either. Installation of a vacuum elevator takes a few hours. The elevator is reliable - it is impossible to get stuck between floors or fall down. A sensor will detect depressurization of the upper part of the shaft (in the unlikely event that this happens, because the electromagnetic locks monitor the locking of the doors) and apply a brake mounted on the cab roof. When the electricity is cut off, the valve at the top closes automatically and the cabin slowly slides down as air seeps into the upper area. Ge")

The signs of the closest analogue, which coincide with the essential signs of the useful model, are the presence in the pneumatic elevator of a mine limited by walls, with a door, a cabin with a piston fitted to the walls of the mine, cabin stoppers, a pneumatic pump, a pneumatic system. oh

The technical result of the useful model is an increase in the reliability and safety of the elevator.

The reasons preventing the achievement of the technical result when using the closest analogue are (57) low reliability due to the need to seal the entire mine and the impossibility of creating a vacuum when the electricity is turned off, lack of safety due to the need to create and maintain rarefaction of the air in the mine area.

The useful model is based on the technical task of improving the construction of a pneumatic elevator. With 50 The given technical problem is solved by the fact that in a pneumatic elevator, which includes a shaft limited by walls, with a door, a cabin with a piston fitted to the walls of the shaft, cabin stoppers, a pneumatic pump, a pneumatic system, according to a useful model, the shaft is made airtight below the upper floor, the piston is located under the cabin, the pneumatic pump is made of a booster, the pneumatic elevator is supplied with an emergency air pump, the door below the upper floor is made of hermetically closing ones, the elevator shaft is supplied with a support chamber from below. - Between the set of essential features of a useful model and the technical result achieved when using it 4! there is the following causal relationship. The presence of a cabin with a piston fitted to the walls of the mine and made under the cabin and a pressure pneumatic pump will allow the cabin with passengers not to be in it. in a suspended state, but rely on air under pressure, which is pumped up with the help of a pump, which is much more

Te) 20 reliable. It will increase the reliability of making the mine hermetically sealed only below the top floor, as well as making the doors closed hermetically only below the top floor. It will increase the safety of the pneumatic elevator by supplying it with an emergency air pump that pumps it up. The presence of a support chamber will ensure reliability when supplying air from below.

A useful model is illustrated with graphic material, where figures 1, 2 and C show a diagram of an elevator for a 29-story building. In figure 1, the elevator cabin is on the first floor, in figure 2 - elevator cabin c is on the second floor; in figure Z - the elevator cabin is located on the upper, third floor.

The pneumatic elevator contains a shaft 1 (for example, cylindrical) bounded by walls 2, a cabin 3, a pneumatic pump 4 connected to a pneumatic system (not shown in the figures). Shaft 1 is provided with a support chamber 5 to provide air support, a hermetically closing door b on the lower floors and a non-hermetic door 60 on the upper floor. A piston 8, made of sealing material, fitted to the walls 2 is located under the cabin C.

The pneumatic elevator works in the following way. From the high-pressure pneumatic pump 4 (for example, with a pressure of 5900-15000Pa, which allows you to ensure the lifting capacity of the elevator up to 200 kg), air is injected into the support chamber 5, which presses the piston 8 from below, pushing the cabin up. The intermediate stop on the floor can be provided with stoppers (not shown in the figures) of the cabin 3. Ensuring the necessary lifting speed is regulated by the performance and pressure of the pneumatic pump 4. To move down, the pneumatic pump 4 is turned off, the pressure under the cabin C drops, and it is under the influence of gravity descends

The speed of descent can be regulated by the exhaust valves of the pneumatic system (not shown in the figures), controlled from cabin 3, while its free fall is excluded.

In case of emergency disconnection of the pneumatic pump 4, the cabin C can be raised up due to the pumping of air by the emergency air pumping pump, for example, a foot pump (not shown in the figures).
