Hybrid power elevator and working method thereof

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...

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
