Vertical circular elevator

Abstract

A vertical annular elevator is mainly composed of a shaft, lift cars, a transmission tractor, a power source and a control system, and the multiple lift cars do closed annular motion. The elevator integrates the advantages of an existing elevator and an escalator, and overcomes the defects of the existing elevator and the escalator.

Description

Technical Field

[0001] The present invention relates to a vertical circular elevator. Background Art

[0002] There are mainly two categories of existing elevator types. One is the vertical single-car elevator in which a single car runs up and down in a vertical shaft, and the other is the escalator that runs obliquely. The vertical single-car elevator often has accidents such as the car falling or overshooting due to brake failure, endangering human lives. Moreover, passengers often have to wait for a long time. Although escalators do not require passengers to wait and allow continuous boarding, they run slowly and often cause passengers to be injured or even killed due to unstable turning plates, and passengers lack a sense of security. Summary of the Invention

[0003] The present invention is a vertical running elevator with double rows of multiple cars, characterized in that: multiple cars corresponding to the floors rise and fall sequentially in a clockwise or counterclockwise direction and move in a closed loop in the shaft. Passengers on each floor can simultaneously choose to enter the upward or downward car, and the cars continuously transport the passenger flow on each floor. This elevator combines the advantages of the existing two types of elevators and eliminates their defects.

[0004] The elevator of the present invention consists of a working system and a control system. The working system mainly includes accessories such as a shaft, cars, a driving tractor, a power source, tracks, and buffers. The control system is divided into automatic intelligent control and manual control.

[0005] The car adopts a lightweight and high-strength material skeleton and is enclosed by lightweight sheets. High-strength and lightweight materials include aluminum alloy, high-strength lightweight honeycomb board, carbon fiber composite material, and other applicable materials.

[0006] The car may also be assembled from units of high-strength lightweight materials.

[0007] The driving tractor is most preferably a "traction belt", which refers to a belt-shaped arrangement formed by a chain, rope, conveyor belt, rack, gear, and other applicable devices that can traction the movement of the car.

[0008] A high-sensitivity high-speed motor type power source is adopted to shorten the elevator response time and increase the running speed. Or multiple motors are synchronized, and the intelligent control system designates one or several motors to be put into or taken out of operation according to the load condition.

[0009] The traction belt transmits force and traction to the car through a coupling member, and the coupling member is essentially a clutch, adopting a buckle, clamp, claw disc, jaw type, stop block, or other devices that can reliably transmit the traction force and can be connected or separated when needed. Now disclose Figure 2An umbrella-shaped connector: half of the connector is in the shape of the Chinese character "个", which is combined with the other half of the large hole plate 1 to form a whole piece, and is matched with the small hole plate 2. The "人" in the character "个" is two oblique rods 3, which can be opened into "个" by springs 4 and hinges 5, and can also be closed and overlapped with the middle vertical rod 6. The diameter of the hole in the large hole plate is slightly smaller than the diameter of the umbrella after opening, so that the oblique rod can be reliably connected to the large hole plate after closing, passing through the large hole and then opening. When the small hole is pressed down from the top of the umbrella, the two oblique rods are closed, and the umbrella and the large hole plate can be separated and the connection is released. The vertical rod 6 and the large hole plate 1 are fixed to the transmission tractor and the car respectively, so that the two can be connected or disconnected. The example of the flat character "个" is used to facilitate understanding and drawing. It is more practical to use a three-dimensional "umbrella" with multiple oblique rods. The action of the connector is controlled by a program control system or a numerical control system.

[0010] The most suitable number of cars for the present invention is "(number of floors*2)-1". When the elevator is running, the cars rise or fall sequentially in a clockwise or counterclockwise direction under the action of traction force. After reaching the top or bottom, they move horizontally under the action of the set horizontal driving force to fill the corresponding empty spaces in another row of cars and continue to participate in the operation of another row of cars.

[0011] The beneficial effect of the present invention is that each floor has a car that can go up and down immediately for passengers to choose to take at any time. There will be no car top collision or fall accident. People on each floor can take the car in a continuous stream, and the transportation flow is several times higher than that of existing elevators. The elevator of the present invention is not only suitable for general buildings, but also particularly suitable for large public places with large and concentrated traffic such as stations, subway stations, airports, shopping malls, theaters, gymnasiums, schools, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Embodiment 1

[0031] Taking the counterclockwise operation of the car as an example. As Figure 1 shown, all the cars 2 in the elevator shaft 1 are arranged in two vertical columns, with two cars on each floor, but there is a vacant car position on the left side of the top floor. After the elevator receives the operation instruction, the electric push rod 5 pushes the car 2.8 on the right side of the top floor to the left vacant position, the right traction device 4 starts to move upward, pulling the car upward, a vacant position appears at the bottom right, the translation electric roller 6 starts, and the car 2.9 on the left side of the bottom floor is translated to the right. At the same time, the braking buffer 7 brakes and locks the car 2.10 to prevent it from moving downward. After the car 2.9 completely leaves the left side, the buffer 7 stops the braking function and instead executes the buffering function, allowing the car 2.10 to smoothly move downward to the bottom floor under the traction of the left traction belt 4. At the same time, a vacant position appears at the top floor of the left car, and the elevator continues the next new cycle. All the actions described above are automatically completed instantaneously under the control of the intelligent program, giving the passengers a feeling of continuity and smoothness.

[0032] Of course, the electric push rod in this example can be replaced by a movable fixture, suction cup, hook or more other methods on the top track of the shaft. Similarly, the translation electric roller at the bottom can also be replaced by a linked moving flat plate or slide rail or an electric pull rod cooperating with a pulley, or more suitable methods. The power for the car running transmission and traction may also be considered to be provided by magnetic levitation. The connector may use an electromagnet. All of the above belong to conventional process designs, and there are many methods, which are too numerous to enumerate.
