Problems solved by technology

However, the pneumatic elevator device relies on the pressure difference between the upper and lower parts of the car to raise the car. Since the air pressure decreases with the increase of altitude, when the building is taller and the number of floors is large, the air pressure at the lower part of the car decreases with the height. If the air pressure is small, the air pressure above the car needs to be smaller. At this time, the pumping capacity of the air pump needs to be increased. Therefore, the power of the air pump is required to be higher, and the cost investment is large. Therefore, the pneumatic elevator device is installed at a height of about 10 meters. Suitable inside buildings, not suitable for taller buildings

Embodiment 1

[0049] Embodiment one: figure 1 As shown, a hybrid elevator includes an elevator shaft 1, an elevator guide rail 2 arranged in the elevator shaft 1, a car 3 located in the elevator shaft 1 and running up and down along the elevator guide rail 2, the The top of the car 3 is slidably connected with a sealing cover 4, and the sealing cover 4 is sealed and matched with the wall of the elevator shaft 1, and there is a closed air storage space 5 between the sealing cover 4 and the wall of the elevator shaft 1 above it. The elevator shaft space below the sealing cover 4 is connected to the atmosphere, and the top of the air storage space 5 is provided with an exhaust valve 6, and the car 3 is pulled by the air pressure difference between the upper and lower sides of the sealing cover 4 when the car 3 descends. .

[0050] The elevator also includes a mechanical traction system that pulls the car 3 upward.

[0051] In this embodiment, the mechanical traction system includes a hoist 7...

Embodiment 2

[0081] Embodiment two: if Figure 4 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is:

[0082] The winch is arranged above the elevator shaft, and the contact between the steel wire rope and the side wall of the shaft and the sealing cover is sealed.

[0083] The elevator car of the present invention relies on mechanical power traction when going up, the rising height is not affected by changes in air pressure, runs smoothly, and has no upper limit for the upward height; while the elevator car going down depends on the gravity of the car itself and the air pressure difference between the top and bottom of the sealing cover , basically no energy consumption, energy saving and environmental protection, low cost, and safe and reliable. The downward speed of the car is always controlled by the pressure of the air, and there will be no rapid drop of the car caused by the breakage of the steel wire rope or the failure of the...

Abstract

The invention discloses a hybrid power elevator and a working method thereof. The hybrid power elevator comprises a lift shaft, an elevator guide rail, a lift car and a mechanical traction system dragging the lift car to ascend. The upper portion of the lift car is in sliding connection with a sealing cover. The sealing cover is in sealing fit with the wall of the lift shaft. A closed air storage space exists between the sealing cover and the wall of the lift shaft above the sealing cover, the space of the lift shaft below the sealing cover is communicated with the atmosphere, the top of the air storage space is provided with a vent valve, and the lift car is dragged through the difference of the air pressure above the sealing cover and the air pressure below the sealing cover during descending of the lift car. The lift car is dragged through mechanical power during ascending, running is stable, and the ascending height is not limited. The descending of the lift car relies on the gravity of the lift car and the difference of the air pressure above the sealing cover and the air pressure below the sealing cover, energy consumption does not exist basically, energy is saved, environmental friendliness is facilitated, cost is low, the descending speed of the lift car is controlled by air pressure all the time, and the situation of passenger casualties caused by rapid descending or ascending of the lift car due to fracture of a steel wire rope, failure of a traction mechanism and the like cannot occur.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to a hybrid elevator and a working method thereof. Background technique [0002] A common elevator is a vertical lift powered by an electric motor, equipped with a box-type gondola, which is used for multi-storey buildings to take advantage of people or carry goods. The elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The structure of an elevator usually includes four major spaces and eight systems. The so-called four major spaces refer to: the machine room part, the shaft and the pit part, the car part and the landing part; the eight major systems refer to: the traction system, the guidance system, the car Car, door system, weight balance system, electric drive system, electrical control system, and safety protection system, so the elevator structure that uses mechanical equipment to pull the car to ru...
