Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved monorail vehicle and operating method, and a monorail as an urban transportation means, which is capable of downsizing the vehicle and drastically reducing the construction cost, and being adaptable to mass transportation despite being a small vehicle. This is related to a smooth connection operation system between routes and bus routes.

[0002]

2. Description of the Related Art The monorail system is the preferred method for urban transportation. However, considering the actual construction, the construction cost was too high to be implemented. The reason for this is that the conventional monorail has a closed signaling system, so high-density operation cannot be performed due to the operating system, so it was necessary to use medium and large vehicles for mass transportation. This is because if a medium-sized or large-sized vehicle is used, the track girders and struts that support the medium-sized vehicles are also required to have high strength, and the track girders and struts are large in size to increase the required installation space. In addition, the construction period is prolonged, causing a great deal of inconvenience to local residents. On the other hand, if the vehicle is made extremely small, the construction costs of track girders, vehicles, stations, etc. will be drastically reduced, and it will be possible to keep it within the feasible construction cost and shorten the construction period.

[0003]

However, in the case of a small vehicle, high density operation which shortens the operation interval is required in a densely populated area. I couldn't handle it.
Here, the blockage signal system is a system that continuously divides the entire track into sections of a certain distance from the end, and manages so that no two or more vehicles can exist in any one section in any case. This ensures safe train operation. However, in the conventional block signal system, when high-density operation required for a small vehicle is required, the distance of one section is further shortened, and the number of sections to be managed is extremely increased, so that the signal system is It becomes complicated and not preferable for operation management. In order to miniaturize the vehicle and construct a profitable monorail, it was necessary to develop a new operation system suitable for safe high-density driving.

Further, in urban areas, people are crowded in the central area and residential areas, and road congestion is remarkable, but in the surrounding suburbs there are few people and the roads are vacant. It is only in the center and residential areas that urban transport such as monorail is needed, and in the suburbs conventional bus transportation is sufficient. If the monorail is constructed in the suburbs where road traffic is not congested and the monorail is not needed, the number of passengers will be insufficient and it will not be profitable. Moreover, in reality, there are many passengers traveling back and forth between the center and the suburbs. In other words, considering the fact that many passengers travel back and forth between the central area and the suburbs, it is inconvenient for passengers in the suburbs to change trains only by constructing a monorail only in the crowded central area and residential areas. Does not satisfy the request. On the other hand, there is a problem in that if the construction is done widely in the suburbs, the construction cost and the maintenance cost will rise and it will be impossible to construct profitably.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems. The structure is such that a transmitting device for transmitting a signal wave is attached to the front part of a vehicle and the signal wave is applied to the rear part of the vehicle. A control device is provided which is provided with a reflecting device which receives and transmits a reflected wave, and which receives a reflected wave from a reflecting device provided at the rear part of the preceding vehicle in the front part of the vehicle to measure the distance to the preceding vehicle and make a calculation judgment. By being provided, it is characterized by slowing down or braking when the vehicle distance is shorter than the braking stop distance.In addition, from the outer side surface of the traveling frame equipped with traveling wheels and rolling wheels that are in rolling contact with the track girder on the inside. The present invention is characterized by a trolley vehicle in which a loading frame on which a bus wheel can be placed is extended, and a wheel stopper is provided on the loading frame, and a bus which can be loaded on the loading frame of the trolley vehicle by self-propelling.

That is, according to the present invention, the monorail vehicle itself is reduced to the size of a small bus, and the vehicle is operated independently and without connecting each vehicle, thereby drastically reducing the weight load on the track girder and improving safety. However, it became possible to reduce the construction cost of the track girder extremely. However, since the small vehicle according to the present invention has a limited number of transport personnel, it cannot support mass transportation unless high-density operation is performed to shorten the operation interval. Since high-density driving is difficult with the conventional blockage signal system, the following vehicle transmits a signal wave to the preceding vehicle, receives the reflected wave returned from the preceding vehicle, and constantly monitors the distance between the two vehicles. The acceleration and deceleration (braking) are automatically controlled to keep the vehicle-to-vehicle distance at a predetermined value or more to prevent a rear-end collision. By adopting this method, a safe monorail can be constructed at a practicable cost.

Furthermore, in the suburbs where the population density is low, the introduction of large and medium monorails, which conventionally requires a great deal of cost for construction and maintenance, lacks rationality as an infrastructure for city planning. Buses are a reasonable means of operation. However, in reality, many passengers move between the central part and the suburbs, and many passengers endure the trouble of changing vehicles. The present invention divides the main body of the monorail vehicle into a bogie and a route bus, provides a space in which the route bus can be loaded and fixed in the bogie vehicle, and operates the monorail track while the route bus is fixed on the bogie vehicle. Is. For that purpose, the carriage frame is provided on the bogie vehicle, and the platform for hoisting on the carriage frame is provided while driving the bus. It is preferable that the floor surface of the bus placed on the carriage matches the floor surface of the platform of the monorail station.

[0008] In order to ride a route bus on a bogie,
A slope is provided on the general road on which the route bus runs. The dolly is a monorail track. If you set up a platform where the bus can be driven while driving in a bogie, and fix the wheels of the bus on the frame of the bogie, passengers of the bus will be on the monorail without changing trains. After that, the monorail truck carrying the bus climbs up while traveling and waits at a position close to the monorail track,
It is possible to enter the monorail main line and run on the monorail track by switching the points at a timing that keeps a predetermined distance from other monorail vehicles.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a monorail vehicle is driven by one vehicle that is as small as possible. 20 to 50 people, preferably 30 people. By downsizing the vehicle, the cost of supporting columns and other equipment to hold the track girder will be drastically reduced, and the land for monorail installation will also be drastically reduced.

The operation system of a monorail vehicle is shown in FIG. 1 is a monorail vehicle, which is a fixed part of the track girder 2
Drive upward in the direction of the arrow. 3 indicated by a broken line is a traveling wheel. At the front of the following vehicle, there is provided a transmitter (not shown) for transmitting a signal wave shown by a chain line, and this signal wave is received by a reflector at the rear of the preceding vehicle and is also a reflected wave shown by a chain line. To send. In addition to such a transmitting device, a control device (not shown) is provided at the front of the following vehicle in order to receive the reflected wave and measure and determine the distance from the preceding vehicle. The transmitting / receiving device is not limited to the front part or the rear part of the vehicle, and it is possible to select an appropriate part such as protruding from the roof of the vehicle. This control device automatically reduces the traveling speed when it determines that the measured distance is shorter than the preset distance X, and automatically stops when the measured distance is shorter than the preset distance Y. Then, the output signal is transmitted to the wheel 3 or the wheel 8 shown in FIG. Naturally, the distance Y is the distance X
Shorter than. The distance X and the distance Y are individually specified in consideration of various requirements such as brake performance, vehicle weight, traveling speed, slippage between the vehicle and track girder so that the following vehicle does not collide with the preceding vehicle. Set in advance.

If the vehicle distance between the preceding vehicle a and the following vehicle b is x and the maximum braking stop distance is Lmax, then x
When ≤Lmax, the following vehicle is slowed down by braking, and x> Lmax. On the other hand, when x> Lmax, the following vehicle keeps the current speed or accelerates to maintain a predetermined traveling speed. To That is, safety is ensured by maintaining the vehicle-to-vehicle distance at a predetermined value or more. Here, Lmax (m) = Vbmax / 7.2β,
(Vmax = speed of the following vehicle, β = braking deceleration.) In order to maintain the vehicle-to-vehicle distance, this calculation formula is an example, and other calculation formulas can be used.

As the signal wave, an ultrasonic wave, a laser beam,
Electromagnetic waves such as microwaves and millimeter waves can be used. By using these signal waves, vehicles such as ITS system, optical sensor, and SS radio are adopted to operate the vehicle.

Next, a method of connecting the vehicle and the bus according to the present invention will be described with reference to FIG. 4 is monorail track girder 2
It is a trolley vehicle that can drive the vehicle, and 5 is a route bus on the trolley vehicle 4. Reference numeral 6 denotes a traveling frame that runs while straddling the track girder 2, and traveling wheels 3 for making rotational contact with the track girder 2 are provided at the upper and lower ends of the traveling frame 6. Reference numeral 8 denotes a stable wheel, which is in rotational contact with a side surface of the track girder 2 at a portion extending downward of the traveling frame 6. A portion extending below the traveling frame 6 and the stable wheel 8
As a result, the carriage 4 can safely travel on one track girder 2. The traveling frame of a general type monorail vehicle has basically the same structure as the traveling frame according to the present invention.

From the outer side surface of the traveling frame 6, the mounting frame 9 extends outward substantially horizontally, and then extends upward. The horizontal portion of the mounting frame 9 needs to have a width that allows the bus wheels 10 to ride while traveling by themselves. The axles of the bus wheels 10 of the bus 5 and the upper part of the traveling frame 6 must not touch. In addition, since the ordinary route bus 5 is connected to the bogie 4 to operate as a monorail,
A transmission device (not shown) for transmitting the above-mentioned signal wave and a control device (not shown) for receiving the reflected wave from the preceding vehicle and measuring the distance and making a calculation determination to adjust the traveling speed of the vehicle 4 are provided. . The rear part is provided with a reflecting device which receives and reflects the signal wave transmitted from the further following vehicle 4. Therefore, the trolley vehicle 4 connected to a general route bus can travel on the track girder 2 while automatically adjusting the speed like a general monorail vehicle.

As shown in FIG. 2, it is significant that the carriage 4 carries a bus 5 and travels along the track girder 2 in the same manner as a monorail carriage. As shown in FIG. 3, 11 is a monorail main line, which is laid in a densely populated area, and 12 is a monorail station. However, passengers move in various directions away from the densely populated area, such as the a direction, the b direction, and the c direction. If a monorail main line is laid on each of them, an imbalance will occur between the number of passengers and capital investment, making it unprofitable, and eventually it cannot be laid. In the present invention, a direction, b
Bus lines for each direction such as direction and c
The vehicle body can be mounted on the carriage 4 shown in FIG.

As shown in FIG. 3, the bus route a is branched into a switching line 13 at a monorail main line 11 and a switching point A. Similarly, at the switching point B, the monorail main line 11 and the switching line 13 are branched. In the present invention, the bus routes a, b, c, ...
In between, it is possible to ride on the monorail carriage 4 on the switching line 13 while driving the bus 5. Bus wheel 1
After fixing 0 to the mounting frame 9 with a stopper, the trolley vehicle 4 travels on the switching line 13, and the trolley vehicle 4 on which the bus 5 is placed can be sufficiently interrupted to form a gap between the leading monorail vehicle and the trailing monorail vehicle. , It can be inserted from the switching point, and like other monorail vehicles, the vehicle can be driven while controlling the vehicle interval so as not to approach within a predetermined distance. In this way, even if you take a local bus from the suburbs, passengers will be able to fully enjoy the benefits of the monorail because they will be riding in a vehicle that runs as a monorail without changing trains in a densely populated area.

FIG. 4 shows a monorail main line 11 and a switching line 1.
3 is a side view of a riding platform 15 for boarding the trolley vehicle 4 of the bus 5 and the main line 11 is illustrated by omitting columns. FIG. 5 is an explanatory plan view of FIG. As shown in FIG. 4, since the switching line 13 is inclined, the height difference between the monorail main line 11 and the bus line is eliminated. However, since the monorail needs to have the height of only the mounting frame 9, in order to ride on the carriage 4 while the bus 5 on the general road runs, the riding platform 15 for the height of the mounting frame 9 is required. Requires. Reference numeral 16 is an inclined surface for riding the bus and leading it to the platform 15. The connecting track 17 called the point at the tip of the switching line 13 is 3 in FIG.
It is possible to get on a local bus in any direction, and it is connected to three bogie vehicle tip positions 18.

First, the carriage 4 stands by at the carriage vehicle tip position 18 connected to the connecting track 17. The bus 5 climbs up the slope 16 and slowly gets on the horizontal plane of the mounting frame 9 from the riding platform 15. When the bus 5 gets on stably, the bus is stopped and the bus wheels 10 are fixed to the mounting frame 9 with stoppers (not shown). At the dolly vehicle tip position 18 in the central portion in FIG. 5, the bus 5 is on the dolly vehicle 4.
In this state, the trolley vehicle 4 passes through the connecting track 17, rises while traveling on the switching line 13, and stands by at the standby position at the same height as the monorail main line 11. The connecting point 17 is usually on the main line 11 side as the switching point, but if the preceding vehicle and the following vehicle maintain a sufficient distance, or if the following vehicle waits for a while, it is indicated by an arrow in FIG. like,
Switch to the switching line 13 side and change the bogie 4 to the monorail main line 1
Can be induced to 1. After the carriage 4 is introduced to the monorail main line 11, the connecting track 17 is immediately switched again to the monorail main line 11 side to maintain a normal track.

As described above, the case of entering the monorail track from the bus route has been described. However, when exiting from the monorail track, the reverse of the case of entering may be performed, and the carriage 4 enters the switching line 13 from the switching point and descends. Stop at the trolley vehicle tip position 18. After that, if the stoppers for the mounting frame 9 and the bus wheels 10 are removed, the bus 5 is self-propelled, gets down to the platform 15, passes through the inclined surface 16, and the bus can thereafter travel on a normal bus route.

In the present invention, a carriage 4 on which a bus 5 is placed
However, a general-purpose monorail vehicle 1 can also be mixed and run on the monorail main line 11. Therefore, the carriage 4
Must have the same transmission / reception and control functions as the monorail vehicle 1. Also, at the monorail station 12, the floor of the bus 5 on the carriage 4 is located at the monorail station 1 so as not to interfere with getting on and off the platform.
It is preferably coincident with the floor surface of the second platform. The floor surface of the bus here is a floor surface when getting on and off, and there may be stairs or a slope in the bus.
Furthermore, the floor of the bus itself can be lifted (for example, a lifting mechanism is provided on the stairs for lifting), or the platform of the monorail station 12 itself can be lifted, but the former structure is Target.

[0021]

According to the present invention, in which the operation system of the monorail is improved and the route bus is mounted on the bogie for the monorail, it is possible to perform safe and high-density operation without the need for passengers to transfer, and to miniaturize the vehicle body and the structure. It is possible to provide an urban transportation network using monorails that can be constructed at a reasonable cost while maintaining safety.
