The present invention relates to an air floating transportation system, and more particularly, can be moved after the carrier is supported by the compressed air injected from the track can significantly reduce the cost of facility construction and energy use through the weight of the carrier. To an airborne transportation system.

In general, a large transport vehicle such as a vehicle, such as a train is adopted to drive the wheels by the engine or to move by using electric power.

However, such a transport vehicle has a limitation in speed, increases the consumption of fossil fuels and causes depletion of resources, and exhaust gases such as carbon dioxide generated during the combustion of fossil fuels cause wastewater to cause environmental pollution. Done.

Therefore, in recent years, research is being conducted to develop alternative energy for reducing the consumption of fossil fuel, and to develop a transport vehicle using the alternative energy and a system for operating the same.

An example of the above-described future transportation means may include a maglev train or an air flotation train.

The magnetic levitation train or air levitation train floats in the air to reduce friction at high speed, and moves with its own propulsion with propulsion devices such as propellers, jet engines, or linear motors using magnets for propulsion in the air.

In addition, the necessary power is supplied from the outside through the electric wire to move along a track or railway specially manufactured for smooth operation at high speed.

Magnetic Levitation (Magnetic Levitation) is to control a repulsive force caused by magnetism to raise a predetermined object to a certain height on the surface, it can be classified as Superconducting (Normal Conduction) Magnetic Conduction (Normal Conduction Magnetic Levitation).

Superconducting magnetic levitation is a powerful superconducting magnet produced by superconducting phenomena (e.g., the loss of electrical resistance of metals, alloys, semiconductors, and / or organic compounds at low temperatures below a certain critical temperature and exhibits fully diamagnetic properties). By using the repulsive force, by using the superconducting Meissner effect (when a magnet is placed on the superconductor, it is injured by using the repulsive force generated in the magnet, and has the advantage of realizing a stable injury without a special controller) have.

Unlike the superconducting magnetic levitation, the phase-conducting magnetic levitation causes injury by using a repulsive force (or attraction force) caused by magnetism at a normal temperature, and a phase-induced magnetic levitation (EMS, Electromagnetic Suspension (Levitation) ), Rebound floating method (EDS, Electrodynamics Suspension (Levitation)) and induction floating method (EDS, Electrodynamics Suspension (Levitation)).

In the suction floating method, a magnetic material such as iron is disposed on the primary side or the stator, and an electromagnet is positioned below the magnetic material, thereby utilizing the property of attracting the electromagnet to the magnetic material, while maintaining a constant gap between the magnetic material and the electromagnet. If possible, install the automatic control device so that it floats stably.

The repulsion floating method utilizes repulsion when the same polarities of magnets are close to each other. The repulsive floating method uses a repulsive force generated between a permanent magnet that generates magnetic force and an electromagnet whose magnetic force is controlled by a predetermined control device.

Inductive floatation is characterized by the fact that magnetic lines passing through coils made of several turns of conductors, such as copper, change over time (the electromotive force thus created is called transformer electromotive force), and when a given conductor crosses the magnetic field. (The electromotive force thus produced is called speed electromotive force), and a predetermined electromotive force is generated, which is caused to float by using an electromagnetic induction phenomenon in which current flows through the conductor.

Representative energy conversion systems using the magnetic levitation force, such as a magnetic levitation train and a magnetic bearing, the magnetic levitation train generates and controls the magnetic repulsive force (or suction force) between the train and the railway tracks, the magnetic repulsive force (or suction force) It is characterized in that to generate a propulsion force through a predetermined propulsion device at the same time while converting to the floating force, the magnetic bearing is characterized in that to support the rotating shaft in the air by using magnetic attraction force or repulsive force.

Maglev trains have been steadily developed by Germany and Japan under government leadership, and German Maglev trains have been developed by HMB2 (1976) after the concept test of various implementation models on the test track in the early 1970s with the participation of companies such as Siemens and Tissin. TR08 is being tested through Transrapid (TR) 05 (1979), TR06 (1983), and TR07 (1989), and currently plans to build a 1300km track from Shanghai, China to Beijing.

Japan has also been developing magnetic levitation trains since the early 1970s. Japan has developed the MLU (Magnetically Levitated U-shape) series of superconducting magnetic levitation trains for ultra high speed and HSST (High Speed Surface Transport) models for medium and low speed.

In particular, the superconducting repulsion magnetic levitation train, which has been in development since 1962, has been led by Japan's Railway Technical Research Institute (RTRI) since 1970, and produced the ML-100 in 1972 and 7 km in Miyazaki in 1979. On the test track, the ML-500 recorded a top speed of 517 km / h.

In addition, the HSST system, which is a phase-conducting magnetic suction type magnetic levitation train for medium to low speeds, has been developed by Japan Airline since 1973 and has been developed by HSST Corporation for more than 25 years.

The above-described magnetic bearing is to minimize the frictional force of the rotating shaft by raising the rotating shaft in the air by using magnetic attraction force or repulsive force, such as Switzerland, the United States, Japan, etc. to actively study the high vacuum turbo It has been put into practical use even in the stage of application to the spindle system for high speed machine tools, turbo compressor and energy storage flywheel and artificial heart pump, including the molecular pump (TMP).

Magnetic bearings can be used in vacuum or corrosive atmospheres and a wide range of temperatures due to the absence of mechanical friction, wear, low energy loss, semi-permanent life, and no need for lubrication or sealing.

In particular, as the non-contact bearing, the maximum allowable speed can be greatly increased, and the electric control is possible to maintain the rotational accuracy of the rotating shaft with high accuracy, and to maintain the automatic balancing of the imbalance as well as the vibration of the rotating system with the active control. Have

On the other hand, the air flotation train compresses the air and then blows the compressed air to a flat bottom surface at a constant pressure to open the car from the floor, and the control of the car opens and closes the solenoid valve to inject the compressed air through the nozzle to the floor. Gains momentum and control by recoil.

An example of an air-lift train is disclosed in Korean Laid-Open Patent Application No. 10-2000-0006132.

The above-mentioned magnetic levitation train or air-lift train floats in the air to reduce friction at high speed, and moves by propulsion force of the vehicle body with propulsion device such as propeller for jet propulsion, jet engine or linear motor using magnet. .

The necessary power is supplied from the outside through wires and moves along tracks or railways specially designed for smooth operation at high speeds.

However, the above-described prior art is moved by the propulsion device provided in the carrier, so the load of the carrier is inevitably increased.

Therefore, as the load of the carrier increases, energy consumption increases, and it becomes difficult to reach high speeds.

In addition, in order to receive electric power from the outside, the wires should be installed more, but as the speed increases, the wires may sway and breakage may occur, and facility costs may increase.

In addition, there is a problem in that the cost is increased because a complicated control device is required to support and advance the carrier.

The present invention has been made in order to solve the above problems of the prior art, and by injecting compressed air from the track to support the carrier and then converting the compressed air to thrust by the steering blade operation, it is possible to control forward, backward and speed. By eliminating the need for a separate propulsion device in the carrier, it is possible to reduce the weight of the carrier, and mechanical friction with the outside is eliminated, so that the efficiency can be increased at a high speed, and the facility and maintenance costs can be significantly reduced. The purpose is to provide an airborne transport system.

The present invention to achieve the above object,

A track having a predetermined length having a compressed air injection portion; A compressed air generator connected to the compressed air injection unit and supplying compressed air; A carrier movably coupled to the track; A position detecting sensor installed on the track and detecting a position of the carrier; It is characterized in that it is connected to the position sensor comprises a control unit for controlling the operation of the compressed air injection unit and the compressed air generator.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In describing the embodiments of the present invention, it will be described by dividing into two embodiments according to the coupling form between the track and the carrier, and the present invention is not limited to only these two embodiments and can be variously modified. Reveal.

First embodiment

1 is a view showing a first embodiment of an airborne conveying system according to the present invention, Figure 2 is a view showing an example of the movement of the carrier in the airborne conveying system of FIG.

As shown in Fig. 1 and Fig. 2, the air-shape transportation system A according to the first embodiment of the present invention comprises: a track 2 of a predetermined length having a compressed air injection section 3 formed therein; A compressed air generator 5 connected to the compressed air injection unit 3 and supplying compressed air; A carrier 4 movably coupled to the track 2; A position detecting sensor 22 installed on the track 2 to detect a position of the carrier 4; The control unit 6 is connected to the position sensor 22 and controls the operation of the compressed air injection unit 3 and the compressed air generator 5.

In addition, in the first embodiment of the present invention, the track 2 is formed with a rail groove 20 recessed in a predetermined shape on the upper side, so that the lower portion of the carrier 4 can be seated in the rail groove 20 A relatively protruding seating portion 41 is formed.

The depth of the rail groove 20 is enough that the seating portion 41 of the carrier 4 can be inserted at least one third.

The above-described rail groove 20 is a "U" shape or "V" shape, the seating portion 41 of the carrier 4 is formed in a "U" shape or "V" shape to be inserted into the rail groove 20. do.

However, the rail groove 20 of the track | truck 2 and the mounting part 41 of the carrier 4 do not necessarily need to be a "U" shape and a "V" shape. That is, if the carrier 4 is a configuration that can be seated in the rail groove 20 may be variously modified in any form.

In addition, a plurality of compressed air injection unit 3 is formed in the rail groove 20 of the track (2).

At this time, the inside of the track (2) may be formed in a hollow, or may be formed in a blocked structure formed only the through-hole (H) to which the compressed air injection unit 3 to be described later.

The compressed air injection unit 3 includes a predetermined pipe 34, a connecting pipe (not shown) connecting the pipe 34 and the compressed air generator 5, and an injection hole 32 provided at the tip of the pipe 34. ), The injection hole 32 is suitable for the nozzle shape so that a strong injection force can be generated, each compressed air injection unit 3 is further provided with an opening and closing device 36 to enable individual control.

Here, in the case where the inside of the track 2 is hollow, it is not necessary to use a connecting pipe.

In addition, the opening and closing device 36 is connected to the control unit 6, a solenoid valve, a solenoid valve, etc. capable of controlling the opening and closing operation by wireless or wired by the control unit 6 may be applied.

The compressed air injection unit 3 is connected to the compressed air generator 5, which is a device for generating and supplying compressed air of high pressure, and has a structure similar to that of a known air compressor.

Carrier 4 is made in the form of a conventional train or subway to carry people or cargo.

Since the seating portion 41 of the carrier 4 is a portion where compressed air of high pressure is directly injected, it must be made of a strong plate to reinforce rigidity.

In addition, steering blades 44 are horizontally installed at both sides of the seating portion 41 so as to convert the injection force of the compressed air into the driving force, and the rotation angle of the steering blades 44 is adjusted inside the carrier 4. The angle adjusting device 42 is installed.

The steering blade 44 may be installed in other places depending on convenience as well as the side.

Preferably, the steering blade 44 is installed in the horizontally installed shaft 422, the shaft 422 is installed in the angle adjusting device so that the shaft 422 and the steering blade 44 can rotate 360 ° in place. do.

The angle adjusting device 42 includes a known electric motor, a reduction gear linked thereto, and a shaft 422 installed horizontally, but is not limited thereto, and may include various devices capable of adjusting the rotation angle of the steering blade 44. Modifications may be made.

As shown in Figure 1, the steering blade 44 is coupled to the horizontally arranged shaft 422 can be rotated in place in the 360 ° direction, it is installed symmetrically on both sides of the carrier 4 or other seat It is installed to have the same purpose.

The carrier 4 allows the steering blade 44 to be installed, and is exposed to the outside of the carrier 4 in the state in which the steering blade 44 is coupled to convert the compressed air from the track into the driving force.

In addition, a lower portion of the carrier 4 is further provided with a generator (not shown) which is driven by the compressed air to be injected into power.

It is sufficient that the generator is capable of supplying the minimum power necessary for the operation of the lighting device and the steering blade of the carrier 4 and the operation of the air conditioning system.

The track 2 is provided with a plurality of position detection sensors 22 at regular intervals to detect the position of the carrier 4, the position sensor 22 may be installed on the upper and side portions of the track 2, Preferably, it should be installed in the rail groove 20, and the separation distance between these position detection sensors 22 is not specifically limited.

The sensing data of the carrier 4 detected by the position sensor 22 is transmitted to the controller 6, and the controller 6 receiving the data opens and closes the opening and closing device 36 of the compressed air injection unit 3. While controlling the operation, it will also control the operation of the compressed air generating device (5).

That is, basically, when the carrier 4 is detected, the compressed air is injected, and if the position of the carrier 4 is moved, the compressed air is stopped.

For more precise control, it is necessary to estimate the time when the carrier 4 is close and move, and to proceed sequentially in the order of small amount of compressed air injection-> maximum compressed air injection-> stop.

In the above, the injection operation of compressed air is implemented based on time, but it is not necessarily limited thereto, and the injection mechanism of the compressed air may be set through various methods.

As an example of the position sensor 22 described above, an optical sensor may be used, and various types of sensors may be applied.

The position detecting sensor 22 is connected to the control unit 6, and the control unit 6 controls the on / off operation of the compressed air generator 5 and the compressed air injection unit 3.

Since the track 2 of the present invention is usually installed at a very long distance, it cannot be controlled by the single compressed air generator 5 and the controller 6.

That is, if the distance between the compressed air injection unit 3 and the compressed air generator 5 is too far, the injection pressure is lowered, so that the support of the carrier 4 becomes difficult. Therefore, preferably, the control unit 6 and the compressed air generating device 5 are one unit at regular intervals of the track 2, and a plurality of such units are to be provided.
It is a technology that has been used for a long time in hovercraft and the like to move heavy objects by floating them with air pressure so that there is no problem in generating the necessary air pressure.
In the present invention, since there is no device such as an engine that functions as a propulsion function in the carrier itself, the weight can be made very light.
For example, if a passenger occupies about 1 m2, the total weight of the vehicle and the weight of the person is about 200 kg / m2. The pressure of one atmosphere of air on an area of 1 cm2 is close to about 1 kg / cm2, which in turn corresponds to 10,000 kg / m2. If compressed air is ejected from a 10 mm diameter hole at the bottom of the track, the cross-sectional area of this hole is 0.000078 m2, with one hole at a distance of 10 cm, there are 100 holes per m2 and the total cross-sectional area of the hole from which compressed air comes out. Becomes about 0.0078 m2. If the difference between the pressure of the compressed air and the atmospheric pressure is 1 atm, the weight that can be supported by 100 holes 10 mm in diameter is approximately 78 kg. Therefore, if the pressure of the compressed air is at least 3 atm above atmospheric pressure, it is possible to sufficiently support 200 kg / m2 in the air. If the diameter of the air hole is reduced to 2 mm, it is okay to raise the air pressure above 75 atm. This amount of air pressure is a value we can easily get.
If the carrier is not a car, but a lighter one used in factory automation, the pressure of the compressed air may of course be lower.

Hereinafter, the installation and operation of the first embodiment of the present invention will be described.

The track 2 is provided on the ground at a predetermined length over a suitable section. As described above, the track 2 has a hollow shape and a rail groove 20 is provided at an upper portion thereof.

A plurality of compressed air injectors 3 are installed in the rail groove 20, but the position where the compressed air injectors 3 are oriented is preferably set to be distributed without being concentrated on only one part of the carrier 4. Do.

The compressed air injection unit 3 is further provided with an opening and closing device 36, and the compressed air generating device 5 is provided to communicate with the inside of the track (2). The connection between the compressed air generator 5 and the compressed air injection unit 3 has been described above.

In addition, the opening and closing device 36 of the compressed air injection unit 3 is connected to the control unit 6 by wireless or wired, and the compressed air generating device 5 is also connected to the control unit 6.

On the other hand, the above-described steering blade 44 and the angle adjusting device 42 for controlling the same is installed in the lower portion of the carrier 4, the angle adjusting device 42 is an operation control unit (not shown) provided in the carrier (4) Connected with

The carrier 4 may be provided with a plurality of passenger cars, such as a train or a subway. Each passenger car is provided with the aforementioned steering blade 44, the angle adjusting device 42, and a driving control unit (not shown).

The completed carrier 4 is seated in the rail groove 20 of the track 2.

Thereafter, when the compressed air generated by the compressed air generating device 5 is supplied to the compressed air injecting unit 3, and each opening and closing device 36 is opened and the compressed air is injected into the rail groove 20, The carrier 4 is lifted by this.

At this time, the carrier 4 does not need to be lifted too high, and even if only a slight lift, the mechanical contact is broken, so that the frictional resistance to be generated during driving becomes insignificant.

Subsequently, when the steering blade 44 of the carrier 4 is rotated to give an inclination of about 10 ° to 50 °, a part of the blowing force of the compressed air is converted into a propulsion force so that the carrier 4 is advanced.

In the compressed air injection unit 3 of the track 2, the injection of air is performed only when the position sensor 22 detects the position of the carrier 4, and the injection of air is stopped when the carrier 4 moves. .

In order to stop the carrier 4 which has advanced, when the steering blade 44 of the carrier 4 rotates in the reverse direction, the driving force is reversed, and the carrier 4 slows down and stops.

Therefore, forward, backward and speed may be controlled according to the inclination of the steering blade 44.

In particular, since the carrier 4 is moved while being lifted from the track 2, the friction force is not generated, so the speed can be increased even with a small force, and the generation of vibration and noise can be significantly reduced.
Unlike the phase conduction suction type magnetic levitation train, there is no need for a separate control device for adjusting the distance between the carrier and the track.
