[0005]

According to the present invention, in an air-floating traveling vehicle equipped with a carriage that levitates by the blowing force of pressure air, an air supply pipe is laid along a transportation path, and the air supply pipe is provided. A trolley unit that moves with the movement of the dolly by engaging with the trolley unit, and an air guide pipe that supplies pressure air from the air supply pipe to the trolley via the trolley unit Have a skirt to wear.

A reed valve, which is opened by being pressed by a dog provided in the trolley unit, is provided in the air supply pipe at regular intervals.

In addition, a variable flow straightening plate is provided in the carriage so that the angle can be adjusted and the thrust in the traveling direction can be adjusted. In this case, traveling and levitation are controlled by the direction of the straightening vane and the amount of pressurized air.

Further, the bogie may be provided with a propeller that rotates with electricity or pressurized air as a power source for traveling, so that the effect of levitation and traveling can be made independent.

Further, the bogie may be provided with a nozzle for ejecting pressurized air for traveling, so that the effect of levitation and traveling can be made independent.

The above structures may be combined appropriately.

According to the above construction, the trolley unit engaged with the air supply pipe laid along the transfer path moves along with the movement of the carriage, and the dog provided on the trolley unit moves to the air supply pipe. The provided reed valves are sequentially pressed and opened to supply the pressure air to the carriage through the air guide pipe, and the pressure air is held by the skirt on the bottom surface of the carriage to float the carriage. When controlling the levitation and the propulsion at the same time by the straightening vanes, the thrust in the traveling direction is adjusted by adjusting the angle of the variable straightening vanes provided in the carriage. If the effects of levitation and propulsion are provided independently, levitation and propulsion are controlled respectively.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, an air supply pipe 10 is laid along the traveling path of the truck 1. Although the figure shows an example of installation on one side of the travel route, two or more air supply pipes 10 may be laid along the route for reasons such as air supply capacity. The air supply pipe 10 is connected to an air supply facility including a compressor, a reservoir tank, and the like, which are not shown, but can supply a sufficient amount of consumed air. The air supply pipe 10 is fixed to the fixed portion F via an arm A.

The trolley unit 5 is engaged so as to straddle the air supply pipe 10, and the trolley unit 5 is
The structure is such that it can be easily moved in the extension direction of the air supply pipe 10 by following the movement of the trolley 1, and cannot be displaced in the direction perpendicular to the air supply pipe 10. And, as will be described later, the air supply pipe 1
Air is supplied to the carriage 1 from 0 through the trolley unit 5.

An air guide tube 8 is connected from the trolley unit 5 to the carriage 1. The air guide pipe 8 is connected to the carriage 1 at a position eccentric from the air supply pipe 10 as shown in FIGS. The air guide tube 8 is preferably a flexible tube so that the air guide tube 8 can cope with relative movement between the carriage 1 and the trolley unit 5. Further, since the trolley unit 5 is towed by the traveling of the carriage 1, the air guide tube 8 itself or a holding member (not shown), for example, a link mechanism such as a pantograph, is provided, which has sufficient strength. It is configured. Further, instead of the flexible tube, for example, the air guide tube is configured by a tube of several sections that can be arbitrarily rotated, and the holding member is not always required as long as it has strength.

A skirt 2 is suspended around the trolley 1 and a lower peripheral edge thereof, and pressurized air from an air guide pipe 8 is held between a trolley bottom surface 1a surrounded by the skirt 2 and a road surface G. Bottom 1a
The introduction portion 8a is provided with a variable flow straightening plate 3 which is composed of a plurality of guide plates 3a and whose angle can be freely changed.

As shown in FIG. 4, air supply ports 11 are provided on the upper surface of the air supply pipe 10 at appropriate intervals, and one side of the air supply port 11 is fixed to the inside of the air supply pipe 10 as a fixed end 12a. A flexible reed valve 12 is provided. A striker 13 is provided on the reed valve 12 so as to project toward the outside of the air supply pipe 10.

That is, as shown in FIG. 5, at the engaging portion between the trolley unit 5 and the air supply pipe 10, the trolley unit 5 has a seal 7 at the joint with the air supply pipe 10.
Is installed to prevent air leakage, and the air supply pipe 1
A dog 6 for abutting the striker 13 provided on the reed valve 12 to open the valve 6 is provided at a position opposite to the air supply port 11 on the upper surface of the air supply pipe 10 so that pressure air from 0 can flow in.

The reed valve 12 may be a self-returning type manual valve or a valve that opens and closes as the trolley unit 5 travels, such as a solenoid valve that detects and opens the dog 6.

The operation will be described below.

The trolley unit 5 moves on the air supply pipe 10 following the traveling of the trolley 1, and the dog 6 projecting inside the trolley unit 5 has the air supply port 1 on the upper surface of the air supply pipe 10.
The striker 13 of the reed valve 12 provided in 1 is sequentially pressed, and the reed valve 12 bends inward of the air supply pipe 10 and sequentially opens. When the dog 6 passes by, the reed valve 12 is closed by the pressure in the air supply pipe 10.

Thus, the trolley unit 5 includes the air supply pipe 1
Pressure air is sequentially supplied from the air supply port 11 of 0, and is sent to the carriage 1 through the air guide pipe 8. In the dolly 1, the pressurized air is guided between the bottom surface 1a surrounded by the skirt 2 and the road surface G, the pressure causes the dolly 1 to levitate, and jets out little by little from the gap at the lower end of the skirt 2. Therefore, the bogie can travel with a small thrust. And the trolley bottom 1a
The variable rectifying plate 3 including a plurality of guide plates provided at the introduction portion of the carriage 1 can adjust the thrust in the traveling direction of the trolley 1 steplessly by changing its angle.

In the embodiment shown in FIG. 1, an example of propelling by using the air flow discharged rearward by the variable rectifying plate 3 is shown, but as another example of obtaining thrust, a propeller 15 is used as shown in FIG. It may be driven by air or an electric motor, or, as shown in FIG. 7, air may be ejected from the nozzle 16 in the opposite direction to the traveling direction. At that time, the variable rectifying plate 3 is not always necessary, and when the variable rectifying plate 3 is provided, it may be fixed so that air flows out in the vertical direction.

[0024]

As described above, according to the present invention, it is possible to provide a highly safe, small and lightweight transport vehicle, and
Since it is an air levitation type, it is possible to obtain the effect that it is unlikely to be affected by the unevenness of the traveling path.
