Description

[Detailed Description of the Invention] (A) Summary A new passenger trolley is connected between the power car and the trolley of a single-gauge transport vehicle.

Passenger trolleys are used to transport people. this is,
It has seats that people can sit on.

The tilt of the seat in the longitudinal direction is detected by a tilt sensor. In order to rotate the seat back and forth, it is equipped with a rotating mechanism such as a motor, worm, and gears.

The tilt sensor's tilt readings cause the motor to rotate forwards and backwards, automatically adjusting the seat's tilt. This allows humans to sit horizontally at all times.

(b) Technical field Single-rail transport vehicles are installed in hilly areas such as tangerine orchards. It is used for transporting agricultural products, fertilizers, etc.

There is only one rail. Easy to install.

It has a drive mechanism in which a rack and a pinion are engaged. This makes it easy to go up and down steep slopes.

A conventional single-rail transport vehicle is made up of a power vehicle and a truck connected together.

A power vehicle includes a power transmission system such as an engine, a reduction gear, and a pinion, and a braking system.

Braking systems often include a normal stop brake, a constant speed brake, and an emergency stop brake.

A trolley is used to carry cargo. The bogie has the ability to run on rails, but has no power or braking mechanism.

Single-track transport vehicles are not allowed to be ridden by humans.

This is because it is dangerous. Naturally, there is no space for humans to ride.

Since there are no humans on board, the single-track transport vehicle runs unmanned from the beginning to the end of the laid rails.

It also has all the mechanisms for unmanned driving.

At the starting point, one worker loads or unloads the load, unlocks the stop brake, and pulls the engine starting wire hard to start the engine and start the motor vehicle.

The single-track transport vehicle travels unmanned on the rails until it reaches its final destination. At the end of the line, a brake stopper is placed on the ground near the rail. When the motor vehicle reaches this point, the brake rod hanging from the motor vehicle collides with the brake stopper rod. The brake lever rotates and the brakes are applied. The transport vehicle stops.

Another worker at the end of the line unloaded the luggage and
Or put it on the vehicle, shift gears in the opposite direction, and start the engine again.

In this way, single-gauge transport vehicles were, in principle, to run unmanned.

However, with such a transportation method, at least one worker must be on standby at each end of the rail. However, the number of people engaged in agricultural work is decreasing. It is becoming increasingly difficult to have two people on opposite ends of a single-gauge vehicle's rails at all times.

Therefore, the following methods are used:

One person does all the work. Start the single-track transport vehicle at the starting point and walk with the transport vehicle to the final point. Loading and unloading work is done here. Like this 1
Human beings move along with single-track transport vehicles.

The law stipulates that no humans are allowed to ride in single-gauge transport vehicles.

However, single-rail transport vehicles can be faster than walking speeds, so it is not always easy to follow them on foot.

Moreover, there are many slopes, so it can be difficult to walk.

Therefore, in reality, workers often ride single-track transport vehicles instead of walking. It will be easier if you do this.

However, single-gauge transport vehicles were not originally designed to be ridden by humans. It is often dangerous. You may fall and get injured. It is not safe because it takes up a small space on the cargo bed.

The Ministry of Agriculture, Forestry and Fisheries also seems to be willing to approve passenger monorails.

In fact, there are many people who ride single-gauge transport vehicles, and unless they do so, they would not be able to do farm work efficiently. It is unrealistic to ban riding. The intent of the law is to prohibit riding because it is dangerous. However, on the other hand, it would be better to create something with a high degree of technical perfection that is safe to ride.

Since we still ride them today, we should make something that can be ridden with peace of mind.

For this reason, the Ministry of Agriculture, Forestry and Fisheries also seems to be planning to ease restrictions.

(c) Conventional technology for passenger trolleys Since it is prohibited for people to ride on single-gauge transport vehicles, there are no passenger single-gauge transport vehicles that are widely used publicly. Lack of technical knowledge.

JP-A-52-22212 (1977.2.19) JP-A-52-22213 (February 19, 1977) discloses a passenger single-rail transport vehicle. This has a twist on the brakes.

The seats are fixed. There are no improvements to the seats.

(d) Technical issues of passenger single-rail transport vehicles Passenger single-track transport vehicles are required to:

(1) The vehicle can be stopped and started by the passenger's operation.

(2) The passenger trolley on which passengers ride must have an independent brake separate from the motor vehicle's braking system.

(3) Passengers should not be injured by sudden braking.

(4) The rider should be able to maintain a comfortable posture when going up or down slopes, mountains, or valleys.

etc. Among these, (1) and (2) are also applicable to passenger trolleys.
This problem can be solved by installing a new brake.

(3) can be overcome by brake selection and adjustment.

Issue (4) is likely to be overlooked, but it is an important issue.

Single-track transport vehicles run on rails with steep ups and downs, like a jet coaster. However, unlike jet coasters, the length of the vehicle is not long.

If a passenger trolley is added, it will be short in the longitudinal direction and tall in the vertical direction. It becomes vertically long and unstable.

If the relationship between the seats and wheels of a passenger trolley is fixed, the following problems will occur.

When going downhill, gravity tends to cause you to slide forward from your seat.

When going uphill, the center of gravity shifts to the rear,
It will almost make you turn backwards.

If the seat is fixed, there is a risk of falling forward or backward.

In fact, the site where single-gauge vehicles are laid may include slopes of 45°.

Fixed seats may be used if the slope is around ±10°. However, if the angle exceeds 30 degrees, it is dangerous for fixed seats.

It is preferable for the seat to be horizontal not only from the standpoint of physical safety, but also psychologically.

(E) Prior Art of Movable Seats The inventor of the present invention noticed the importance of passenger single-rail transport vehicles from an early stage.

He has also invented several passenger trolleys that can adjust the seat angle depending on the inclination angle.

(1) JP-A-60-60057 (S60.4.6) (2) JP-A-60-60058 (S60.4.6) (3) JP-A-60-76459 (S60.4.30) (4) JP-A-61- 81269 (S61.4.24) (1) has a swing-type swing mechanism. The combined cargo is suspended by supports erected on both sides, and the seats are suspended by their own weight.
It is made to face straight down. Of course, there is also a lock mechanism. Adjust the tilt and then lock.

(2) is effectively the same as the swing type. Fix the arc-shaped rail to the trolley side. There are rollers under the seat. This roller rolls on the rail. Similar to swinging on a swing, the seat rolls back and forth on an arcuate rail and automatically stops facing straight down.

This also has a lock mechanism.

In both (1) and (2), when the tilt angle changes, the rider removes the locking mechanism, adjusts the tilt again, and locks the vehicle. You often have to adjust the tilt angle yourself.

(3) also has a swing-type tilt angle adjustment mechanism.

In (4), one end of the seat is pivoted, and the height of the other end can be changed.

At the other end is a pillar with several bolt holes. Secure the ends of the seat with bolts passed through either bolt hole.

All of these seats allow you to change the direction of the seat back and forth. Moreover, it has the advantage that no particular energy is required to change the inclination of the seat.

However, each has its drawbacks.

(4) requires bolts to be attached and removed, so the angle of inclination can only be changed when the vehicle is stopped. This can only be used when traveling on rails with a constant slope.

In (2), even if the center of gravity is below the center of the arc, the rollers may have a large resistance and may not move smoothly.

(1) and (3) are suspended by swings, so they are easy to rock, but the rocking does not stop immediately at the optimal point, and the seat is not always horizontal when the lock is applied. do not have. The vehicle uses the rider's senses to detect the level and lock the vehicle, but this is not reliable and the vehicle may remain tilted and locked.

However, the biggest drawback of (1) and (3) is that the device is large-scale because the seat is suspended by the swing. This increases manufacturing costs. It also makes the transport vehicle heavier. This reduces the amount of luggage you can carry. Additionally, the left and right sides of the passenger are blocked by pillars.

This makes it inconvenient and cramped to get on and off the train.

A problem common to (1) to (4) is that in all of them, tilt adjustment is not performed automatically and must be performed by the passenger at any time.

This is not only a hassle, but also a safety issue.

(f) Purpose It is an object of the present invention to provide a passenger trolley for a single-rail transport vehicle that is equipped with a mechanism for automatically keeping the seat level.

(g) Configuration The passenger trolley of the single-rail transport vehicle of the present invention uses a motor and an inclination sensor to automatically keep the seat level.

For this reason, the seat is supported by a fulcrum shaft so as to be rotatable in the front-rear direction. Then, the seat can be rotated by an arbitrary angle around the fulcrum shaft using the motor.

A tilt sensor attached to the seat side detects the difference between the seat surface direction and the horizontal direction, and detects when this difference is 0.
The motor rotates to automatically adjust the seat angle.

The contents of the present invention can be summarized as follows.

More specifically, the configurations of the present invention are enumerated as follows.

The passenger bogie of the single-gauge transport vehicle of the present invention includes (1) upper wheels and lower wheels that sandwich the rail from above and below, (2) a vehicle frame that rotatably supports the upper and lower wheels, and (3) the vehicle chassis. (4) a seat pivotally connected to the support box by a fulcrum shaft so as to be rotatable back and forth; (5) a tilt sensor that detects the tilt of the seat; (6) a vehicle. A battery attached to the rack, (7) a motor attached to the support box that can rotate in forward and reverse directions, (8) a reduction gear train that reduces the rotational force of the motor and rotates the seat around the fulcrum axis, and (9) ) A pinion that is fixed to the axle of the vehicle frame and meshes easily; (10) An emergency brake that is installed coaxially with the pinion or via a deceleration/acceleration mechanism; (11) A pinion that allows the passenger to operate the emergency brake. It is more similar to a handbrake.

Among these elements, (1) is the driving function. This is because you are running on rails, so of course you have to be prepared.

(9) to (11) relate to the braking mechanism. This is also used in the passenger trolley mentioned above.

New features include elements (2) to (8) for automatically adjusting the inclination angle of the seat.

(H) Embodiment FIG. 1 is a side view of a single-rail transport vehicle including a single-rail passenger trolley according to an embodiment of the present invention.

Figure 2 is a side view of only the power vehicle and passenger trolley, Figure 3
The figure is a plan view, and FIG. 4 is a rear view.

The single-rail transport vehicle includes a power vehicle 1, a passenger trolley 2,
It is formed by connecting the truck 3.

The single rail that supports these is a rail 4 with a polygonal cross section.
, the rack 5 welded to this side, and the rail 4
It is connected to a support column 6 that supports it on the ground.

The power vehicle 1 is for towing the entire transport vehicle.

The power vehicle 1 has a frame 7 made of aluminum alloy, cast iron, or the like.

An upper wheel 8 and a lower wheel 9 are attached to the frame 7 via an axle.

The power vehicle 1 has a power source such as a fuel tank 10 and an engine 11. The rotational force of the engine 11 is
Through the gear reduction system inside the frame 7,
The signal is transmitted to the drive pinion 18.

Operations such as forward/reverse movement and gear change are performed using the transmission switching lever 13.

By operating the stop-start lever 14, a stop brake (not shown) is activated or released.

A constant speed brake 15 for a power vehicle is provided on the side of the frame to prevent the speed from exceeding a certain level.

In addition to this, there is also an emergency stop brake.

Such motor vehicles have been manufactured by the applicant for some time.

The cart 3 is used to carry luggage.

The truck 3 has a wide loading platform 20 supported by one or two racks 21. The vehicle frame 21 has an upper wheel 22 and a lower wheel 23. Loading platform fences 24 are erected at the front and rear of the loading platform. Fences may also be erected on the sides.

The cart 3 has also been manufactured by the applicant for some time.

The passenger trolley 2 will be explained.

The passenger trolley 2 is supported by a carriage 25 with respect to the rails 4.

The vehicle frame 25 is made of aluminum, aluminum alloy, cast iron, or the like.

The vehicle frame 25 is rotatably provided with an upper wheel 26 and a lower wheel 27 that sandwich the rail 4 from above and below via an axle.

One of the lower axles is provided with an emergency brake 28 and a pinion 29 connected to it and meshing with the rack 5.

When the emergency brake 28 is actuated, a pinion 29 connected thereto stops. Since the pinion 29 is engaged with the rack 5, the carriage 2 stops.

This is activated by the passenger pulling up the handbrake lever 33 when he/she wishes to stop the vehicle in an emergency.

Further, a constant speed brake 31 for a truck is provided diagonally in front of the vehicle frame 25. This is to prevent the speed from increasing too much when disembarking, and to keep the train running at a constant speed. Although it is present in power vehicles, it is also provided in passenger trolleys.

On the vehicle frame 25, a universal joint 60 and a receiving plate 64 are installed.
A basic frame 35 is attached via the.

The universal joint 60 allows rotation in the horizontal direction and rotation in the front-back direction.

For this reason, a vertical shaft 62 is provided upward from the center of the vehicle frame 25.

The vertical shaft 62 can be rotated horizontally.

Above the vertical axis 62 is a horizontal axis 63.

There are brackets 65 on the left and right lower surfaces of the receiving plate 64, and both ends of the horizontal shaft 63 are inserted into holes in the brackets. Therefore, the receiving plate 64 can be rotated back and forth around the horizontal axis 63.

The universal joint 60 thus allows horizontal rotation and longitudinal rotation, but prohibits rotation in the left-right direction. This is natural since the seat must be supported.

The basic frame 35 is bent downward at the front, becomes horizontal, and is connected to the power vehicle 1 by a universal joint 61.

A wide foot pedestal 30 is fixed to the front horizontal part.

The basic frame 35 is a rigid body made by bending iron or the like.

This is supported by a universal joint 61 at the front and a universal joint 60 at the rear.

The front universal joint 61 also has a vertical shaft 66 and a horizontal shaft 67. Allows horizontal and vertical rotation.

The rail may be curved in the vertical direction.
This is a basic skeleton 35 around the horizontal axes 63 and 67.
Since it rotates, it can follow the curve of the rail.

Sometimes the rails are curved horizontally.
This is a basic framework 35 around the horizontal axes 62 and 66.
Since it rotates, it can follow the curve of the rail.

In this way, the basic frame 35 is stably supported on the line connecting the center of the vehicle frame 25 and the universal joint 61 of the power vehicle 1.

The basic frame 35 includes a hand brake lever 33.
is provided so as to be movable up and down. This and the emergency brake are connected by a handbrake wire cable 34.

A U-shaped support box 40 with an upward opening is fixedly installed on the basic frame 35.

A fulcrum shaft 41 is supported on both sides above the support box 40.

The seat 32 has a rotating plate 42 vertically attached to its lower central surface.

A rotating cylinder 51 is fixed in front of the rotating plate 42. The former fulcrum shaft 41 is inserted into the rotating tube 51.

The seat 32 can rotate back and forth about the fulcrum shaft 41. This is to keep the seat 32 substantially horizontal when the rail tilts back and forth.

A DC motor 44 is attached to the side of the support box 40 to provide power for rotating the seat.

Battery 45 for driving DC motor 44
is attached to the receiving plate 64.

FIG. 5 shows the AA cross section and the BB cross section in FIG. 2.

The DC motor 44 is decelerated by a worm gear 46 .

Several gear trains are rotatably attached to the sides of the support box 40.

A first small gear 47 is fixed to the worm gear shaft.

The first small gear 47 is connected to the first large gear 48 located diagonally backward.
It meshes with the

The first large gear 48 is integrated with a second small gear 49 on the side, and is rotatably supported by an intermediate shaft 52.

The second small gear 49 meshes with the second large gear 50.

The second large gear 50 is welded to the rotating cylinder 51. The rotating tube 51 is fixed to the rotating plate 42 and the seat 32.

Therefore, when the motor 44 rotates in the forward and reverse directions,
The deceleration rotational force is transmitted to the rotation cylinder 51, causing the seat 32 to rotate back and forth.

A tilt sensor 43 is attached to the side of the rotating plate 42. This is the direction of gravity and the rotating plate 4
The angle between the two directions can be found.

In other words, the inclination sensor 43 can detect the inclination of the seat in the longitudinal direction.

When the tilt sensor 43 detects the tilt of the seat in the front-rear direction, it drives the motor to rotate the seat in the opposite direction. This way, your seat will always remain level.

There are side handrails 39 on both sides of the seat 32.
A controller 36 is attached to one side of the handrail 39.

In order to reduce the rotational force of the motor 44, a reduction gear train consisting of a worm gear and a spur gear is used in this example.

However, the configuration of the reduction gear is arbitrary. It is also possible to use two stages of worm gears. You can also increase the speed reduction of the spur gear by one or two steps.

Alternatively, a planetary gear reducer can also be used.

The side handrails 39 serve as a handhold when sitting on the seat 32 and when exiting the vehicle, and have the function of keeping the passenger's posture stable during travel.

From the front of the basic frame 35, install the front handrail 3 vertically.
8 are erected.

The passenger sits on the seat 32, places both feet on the footrest 30, and holds the front handrail 38 with both hands. This is a safe position.

Although the braking mechanism is not the main focus of the present invention, since braking is important for passenger trolleys, it will be explained.

Constant speed brakes 15, 31 are provided on both the power vehicle and the passenger trolley.

In order to stop at the starting and ending points, an automatic operating rod (not shown) is suspended from the lower right side of the motor vehicle. This is connected to a stop brake (not visible in the diagram).

When the automatic operation rod hits the stopper rods set up at the start and end points, the automatic operation rod rotates and automatically applies the brakes.

A stop/start lever 14 is attached to the same member as the automatic operating rod. This can be rotated back and forth as shown in FIG.

The forward leaning position is the starting position. The position when standing back is the position when stopped.

The vehicle is traveling with the stop/start lever 13 tilted forward. When you pull this back, the brakes are applied.

However, it is not easy to operate for the passenger of the passenger trolley to reach out and pull up the stop/start lever 13.

Therefore, the foot brake lever 37 is attached to the brake support shaft 53 to which the stop/start lever 13 is attached.

When the foot brake lever 37 is stepped on with the foot, the brakes of the power vehicle are applied.

When the passenger wants to stop the vehicle urgently, he/she steps on the foot brake lever 37 with his foot and pulls up the hand brake lever 33 with his hand.

The foot brake operates the brakes on the motor vehicle, and the hand brake operates the emergency brake on the passenger trolley.

The accelerator wire 55 causes the engine to stop when the foot brake lever 37 is depressed.

The above-mentioned JP-A-60-60057, 60-60058, 60-
76459, 61-81269, etc., by pulling the handbrake, the brake of the passenger trolley was activated and the engine of the motor vehicle connected by wire was stopped.

In the case of the present invention, in order to make such a braking mechanism even more reliable, the brakes of both the power vehicle and the passenger truck are operated simultaneously.

The foot pedestal 30 has a horizontal plate, a front inclined plate 68 in front, and a rear inclined plate 69 in the rear.

The angle of inclination of the forward tilting plate 68 is 50° in this example.

The angle of inclination of the rear tilting plate 69 is 60° in this example.

By automatically changing the seat angle, you can always keep it level. This is the most distinctive part of the present invention.

Therefore, this part will be further explained.

The fulcrum shaft 41 and the rotation tube 51 are located at the seat rotation center Q.
becomes.

The center of gravity G when a passenger sits in a seat differs depending on the person and how they sit.

However, the average center of gravity position G can be determined.

It is mechanically convenient to set the center of rotation Q so that it lies midway along a vertical line drawn from the center of gravity G.

However, experiments have shown that this makes sitting uncomfortable.

This way, when you lean forward, your feet will rest on the foot rests 30.
It will stick out more forward. When I lean backwards, the soles of my feet don't touch the foot rests 30, which makes me feel uneasy.

Even if the seat rotates back and forth, it is better not to change the position of your feet too much. For this reason, the center of rotation Q is positioned in front of the vertical line passing through the center of gravity G.

The center of rotation Q is set approximately 160 mm ahead of the vertical line passing through G (when the rail is horizontal).

The tilt sensor 43 generates an output voltage V according to an angle θ formed by the direction of the sensor with respect to the direction of gravity.

A commercially available product can be used for this.

For example, Accustar manufactured by SPERRY
Use Clinometer (trade name).

FIG. 7 shows the relationship between the tilt angle θ and the output voltage V. In this way, the linearity of the output voltage is extremely good.

The electric circuit will be explained with reference to FIG.

The tilt sensor 43 is attached to the seat and generates an output voltage V according to the tilt angle θ of the seat from the horizontal.

This is the two comparators COMP1,
It is input to the non-inverting input and the inverting input of COMP2, respectively.

The upper reference voltage U is provided by a variable resistor 70 connected between the power supply and ground.

The lower reference voltage D is provided by a variable resistor 71.

U is connected to the inverting input of COMP1, and D is connected to the non-inverting input of COMP2.

The battery 4 is connected to terminals b and c of the DC motor 44.
5's + terminal a and ground g are connected via four switches.

There is a switch between terminals b, c and + terminal a.
SW1, SW3 ₃ are connected.

A switch is connected between terminals b and c and ground g.
SW4 and SW2 are connected.

SW1 and SW2 are opened and closed simultaneously by the output u of COMP1.

SW3 and SW4 are opened and closed simultaneously by the output d of COMP2.

The battery 45 is a rechargeable battery, and is constantly charged by the engine 11.

Current is drawn from a power generation coil 74 provided close to a rotating magnet linked to the engine, through a lighting line 72, to a diode rectifier 73.

Since the electromotive force of the generator coil 74 is alternating current, it is bridge rectified to charge the battery 45.

The effect of Fig. 8 will be described.

When the seat is approximately horizontal, the output V of the inclination sensor is higher than the lower reference voltage D and higher than the upper reference voltage U.
lower.

D≦V≦U (1) At this time, outputs u and d of COMP1 and COMP2 are both at L level. In this case, the motor will not move.

When the rail begins to descend, the seat tilts forward (θ>0), so the sensor output V increases.

When the upper reference voltage U is exceeded (V>U), COMP
1's output u becomes H level. For this reason, SW1,
SW2 closes.

Current flows from the battery 45 in the order of a, b, c, and g. Current will flow in the motor 44 in the forward direction.

The worm gear 46 and gears 47 to 50 rotate at a reduced speed. The rotating tube 51, the rotating plate 42, and the seat 32 tilt rearward.

As the vehicle tilts backward, the sensor output V decreases. Eventually, it will fall into the range of (1). COMP1 output u
becomes L level. SW ₁ 1SW2 opens. Motor 4 stops. This will return it to almost horizontal.

When the rail goes up, the seat tilts backwards (θ<0).

Sensor output V decreases. When V<D
The output d of COMP2 becomes H level. SW3,
SW4 closes. Motor 44 rotates in the opposite direction.

The seat tilts forward. Eventually, the sensor output V becomes
Return to range (1). The motor will stop. The seat is almost horizontal.

In this way, the inclination of the seat is automatically adjusted whether the rail is going up or down.

If the distance between U and D is small, the motor will rotate frequently to maintain the horizontal position.

If the distance between U and D is large, the motor will rotate less frequently, but the seat will not necessarily be level.

Therefore, in both U and D, the seats are
It is chosen so that it is equal to the value of V when the deviation is 2.5° to 3.0°.

This means that the maximum inclination of the seat is 2.5° to 3.0°.

The maximum rail inclination for single-track transport vehicles is 45°. Therefore, it is best to rotate the seat within a ±45° rotation range.

However, when tilted backward, the angle is approximately 15 degrees, and when tilted forward, the angle is approximately 15 degrees.
It is known that if the angle is around 10 degrees, there will be less anxiety.

Therefore, the seat angle adjustment range is at least
30° in front and 35° in back are required.

(k) Effects (1) In the past, people were often forced to ride on single-track transport vehicles that had little room for people to ride.
This was dangerous. The present invention makes it possible to connect a passenger trolley to a single-track transport vehicle.

Agricultural work can be carried out safely and efficiently.

There are seats so you won't feel tired.

(2) Even if the rail is tilted, the seat is automatically maintained horizontally.

To maintain a safe upper body position at all times.

Since it is not manually operated by a human, it does not require any skill from the rider. Frees you from complicated adjustment work.

In other words, even unskilled people can ride it.

(3) The tilt sensor detects the discrepancy between the direction of gravity and the direction of the seat, allowing for highly accurate horizontal control. In terms of motor load. ±2.5゜～±
Although it is sometimes set to about 3.0°, it is also possible to perform high precision control to about ±1.0°.

In this respect, it is superior to the swing type.

(4) Since the passenger trolley is also equipped with a brake, passengers can easily stop the vehicle.
