Description

[Detailed Description of the Invention] (A) Summary A new passenger trolley is connected between the power vehicle and the loading truck of a single-rail transport vehicle. The passenger trolley is equipped with a seat on which a person can sit, and is also equipped with a handbrake. There are 2 or 4 rollers under the seat. The rollers roll on arcuate guide rails fixed on the vehicle frame. The seat moves in the direction of gravity due to the action of rollers and guide rails. This position is fixed by engaging the rack and the pin. Repeatedly, further seat adjustments can be made.

(b) Technical field Single-gauge transport vehicles are installed in hilly areas such as mandarin orange orchards and are used to transport agricultural products, fertilizers, etc. There is only one rail, so it is easy to install. It has a drive mechanism with an engaged rack and pinion, so it can easily go up or down steep slopes.

A 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. The braking system includes a normal stop brake, a constant speed brake,
It often includes an emergency stop brake.

A normal stop brake applies the brakes when the brake rod collides with a hit rod placed on the side of the rail. The brake lever may also be moved by hand.

The trolley only has a running function and has no power or braking mechanism. All luggage will be transported on trolleys.

Single-track transport vehicles are not allowed to be ridden by humans. This is because it is dangerous. Also, there is no space created for people to ride.

Since there are no humans on board, the powered vehicles run unmanned from the beginning to the end of the laid rails.
At the starting point, one worker loads or unloads the cargo, releases the lock on the stop brake, and starts the engine by pulling forcefully on the engine starting wire.
Starting the power vehicle The transport vehicle runs unmanned on the rails. At the end point (the point where the train should stop), a brake bar is placed on the ground near the rail. When the single-rail transport vehicle reaches this point, the brake rod collides with the brake rod, causing the brake rod to rotate. This activates the brakes. 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 generally run unmanned.

However, one worker must be on standby at each end of the rail. The number of people engaged in agricultural work is decreasing, and it is difficult to always have two people working on a single-track transport vehicle.

Therefore, the following method is used as an expedient. One person does all the work. A single-gauge transport vehicle is started at the starting point, then walked together with the transport vehicle to the terminal point, where loading and unloading work is done. In other words, 1
Human beings are constantly moving along with single-track transport vehicles.

The law stipulates that no humans are allowed to ride in single-gauge transport vehicles. However, since single-track vehicles run faster than walking speed, it is difficult to follow them. Moreover, there are many slopes, making it difficult to walk in some places.

Therefore, in reality, workers often travel on single-track transport vehicles rather than on foot.

Single-track transport vehicles were not originally designed to be ridden by humans, so they are often dangerous. You may fall and get injured. It's not necessarily safe because you're riding in a small space on the loading platform.

The Ministry of Agriculture, Forestry and Fisheries also reportedly intends to permit passenger monorails.

In fact, there are many people who ride single-gauge transport vehicles, and they cannot do agricultural work without riding, so it is unrealistic to ban them from riding. It is said that it is prohibited to ride on a bicycle because it is dangerous, but on the contrary, it would be better to create something that is technologically perfect so that it can be ridden safely.

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) Prior art and its problems Since it was forbidden for people to ride on single-gauge transport vehicles, the single-gauge transport vehicle was widely known to the public as a passenger vehicle.
None that were used exist. For this reason, there is little technical accumulation.

Although it is only an idea,
No. 22212 (released on February 19, 1977), Japanese Patent Publication No. 1977-
No. 22213 (published on February 19, 1977) connects a seated car for people to ride between the power car of a single-gauge transport vehicle and a trolley (baggage car).

In the former, the seat car and trolley are separate parts. The latter had new seats built at the front of the bogie.

Both have two independent brake systems. Even if one brake fails, the other brake can be used to stop the vehicle, which prevents the vehicle from running out of control on steep slopes. In fact, for single-gauge transport vehicles that run on steep slopes, it is extremely important to take measures to prevent the vehicle from running out of control.

Single track transport vehicles are used on sloped areas. The angle of inclination to the horizon often reaches 30°,
It can even reach 45 degrees.

The seats of these known passenger cars are fixed. The passenger car tilts according to the slope of the rail. The inclination of the seat also follows the inclination of the rail.

However, it is desirable for humans to always support their upper bodies along a vertical line, regardless of the direction of travel. Even if the rail slopes downward or upward, the seat will not follow the slope of the rail.
It is desirable that it is always approximately horizontal.

(d) Technical issues The following requirements are required for a passenger single-track transport vehicle that carries people.

(1) The vehicle must be able to stop and start by operating the vehicle.
Even if it goes out of control, it can be stopped.

(2) The passenger trolley on which the driver rides shall be equipped with an independent brake separate from the motor vehicle's braking device.

(3) When applying the brakes, due to sudden braking,
Ensure that the driver does not get injured.

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

Problems (1) and (2) can be solved by installing a new brake on the passenger trolley. (3) can be overcome by brake selection and brake adjustment.

Problem (4) seems to have gone unnoticed until now. However, the inventor believes that this is also an important issue.

If the relationship between the seat and the wheels of a passenger trolley is fixed, the user is likely to slide forward from the seat due to gravity, especially when going downhill. On the uphill,
Since your center of gravity is shifted to the rear, you will likely feel like you are going to flip backwards.

The passenger carriage of a single-gauge transport vehicle runs on a track with many ups and downs, like a jet coaster.
However, the length of the vehicle is not as large as that of a jet coaster. Passenger trolleys are short in the front-rear direction, but rather large in the vertical direction. Because it is vertically long and unstable, there is a high possibility of it falling, especially forward or backward.

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

In this way, issue (4) is an important requirement to be overcome.

(E) Structure of the present invention The inventor of the present invention thought that it would be sufficient to make the seat moveable in the front and back directions and change its inclination.

The simplest method is to erect supports on both sides of the vehicle frame.
A pin would be passed through the support and the seat would be suspended from the pin like a swing.

This may be advantageous in some cases. This is because when you sit down, the members on both sides give you a sense of security.

However, in some cases, the support columns and swing suspension parts on both sides may get in the way.

In some cases, it may be desirable to leave the left and right sides of the seat open.

Therefore, the inventor of the present invention came up with the idea of combining an arc-shaped guide rail and a guide roller as a device that causes movement equivalent to a swing.

One of the guide rail and the guide roller is fixed to the seat, and the other is fixed to the vehicle frame.

Furthermore, a rack along an arc is installed under the seat,
A fixed claw that can move in and out of the rack is engaged with the rack.

When the seat adjustment pedal is depressed, the fixing pawl is released from the rack, allowing the seat to move freely along the arc. When the seat adjustment pedal is released, the fixing claws will easily engage again and the seat will be fixed.

(f) Embodiment FIG. 1 is a side view of a single-rail transport vehicle including a single-rail passenger truck according to an embodiment of the present invention, and FIG. 2 is a plan 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 consists of a rail 4 with a rectangular cross section, a rack 5 welded to the side surface, and a support 6 that supports the rail 4 on the ground.

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

The power vehicle 1 has an upper wheel 8 and a lower wheel 9 attached via an axle to a vehicle body 7 that may be made of aluminum alloy or cast iron. The power vehicle 1 further includes a power source such as a fuel tank 10 and an engine 11. Power is transmitted from the centrifugal clutch 12, pulleys, V-belts, etc. to the drive pinion 18 through a reduction gear train.

By switching the gear train, it is possible to move forward or backward. This is done by means of the transmission switching lever 13.

By operating the stop/start lever 14, the stop brake 16 is activated or released.

The constant speed brake 15 provided on the side of the vehicle body 7 is
This prevents the vehicle from driving out of control due to excessive speed when going downhill. The stop brake 16 can stop the power transmission mechanism connected to the pinion 18 in conjunction with the stop/start lever 14 .

The emergency stop brake 17 is activated to automatically stop the power vehicle in the event of an abnormal speed increase when descending a slope.

In this way, the motor vehicle 1 includes a power mechanism and a braking mechanism. The braking mechanism consists of three brakes: a stop brake, an emergency stop brake, and a constant speed brake.

Such a motor vehicle has been manufactured by the present inventor for some time.

The cart 3 is used to carry luggage. The power vehicle 1, the passenger truck 2, and the loading truck 3 are connected to connecting rods 19, 1
Connected by 9.

The truck 3 has a wide loading platform 20 supported by one or two racks 21.

The vehicle frame 21 has two upper wheels 22 and two lower wheels 23 attached to a frame made of aluminum alloy, cast iron, or the like via axles. The vehicle rack 21 is the loading platform 2
0 so that it can be turned left, right, up and down.
Even if the rail 4 is curved up and down or left and right, the carriage 2
1 can turn around and follow the curve of the rail.

Luggage fences 24, 24 are erected at the front and rear of the cart 3. Fences can be erected on the sides if necessary.

FIG. 3 is a rear view of the passenger trolley 2, and FIG. 4 is an enlarged side view.

The passenger trolley 3 is supported by a carriage 25 with respect to the rails 4. The vehicle frame 25 is made of aluminum, amyl 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. On one of the lower axles there is an emergency brake 28
and pinion 2 connected to this and meshing with rack 5.
9 is provided. When the emergency brake 28 is activated, the pinion 29 is stopped and the passenger trolley 2 is stopped.

An arcuate guide rail 30 centered on a center point O above the seat is fixed onto the vehicle frame 25.

In this example, the guide rail has a double arc, and between this, two guide rollers 3
1 and 31 can roll.

A seat 32 is provided above the guide rollers 31, 31. The seat 32 has a backrest and a horizontal plate, so that a person can sit on it. Since the guide rollers 31, 31 roll on the guide rail 30, the seat 32 can move about the center point O.

A pull-up hand brake lever 33 is provided below the side of the seat 32. A handbrake wire cable 34 extends from the handbrake lever 33 and is connected to the emergency brake 28.

A ratchet 35 is fixed around the fulcrum of the handbrake lever 33. When the handbrake lever 33 is pulled up, it is fixed in that position by the ratchet 35. Lever button 33'
When pressed, the handbrake lever 33 is released from the ratchet and can be returned to its original position. A limit switch 36 is provided adjacent to the handbrake lever 33. When lever 33 is pulled up,
A limit switch 36 is actuated by a lever. The on/off signal from the switch 36 is transmitted through an engine stop cord 37 to stop the engine 11 of the power vehicle 1. After the engine stops, the emergency brake 28 starts to apply, and the pinion 2
9 stops, and a braking force is generated on the carriage 2. In this way, the entire transport vehicle can be stopped.

Due to the action of the guide rollers 31 and the guide rails 30, the seat 32 is moved around the center point O.
It is possible to perform a movement similar to a rocking movement in the front and back direction.

The height of the seat board, the backrest, etc. are appropriately set so that the center of gravity G when a person is seated on the seat 32 is directly below the center point O.

It is even more dangerous if the seat is always tilted forward or backward. For this reason, a separate fixing mechanism is provided to fix the seat in an arbitrary position.

The seat adjustment pedal 39 is located at the lower front of the passenger trolley 2,
It is placed in a position where you can step on it.

On the other hand, an arcuate rack 41 having the pin 31 at its center is fixed to the lower surface of the seat 32.

A fixed claw 42 that can be raised and lowered is provided below the rack 41.

The fixed claw 42 and the seat adjustment pedal 39 are connected by a seat adjustment wire cable 40.

When the seat adjustment pedal 39 is not depressed, the fixed pawl 42 is raised and engaged with the rack 41. The inclination angle of the seat 32 with respect to the vehicle frame 25 and the support column 30 is fixed.

When the seat adjustment pedal 39 is stepped on, the fixing claw 42
is lowered and the rack 41 is released. Seat 32 is free to move. Since the center of gravity G, including the human body, is set in advance to be directly below the center point O, if the occupant's posture is correct, the seat 32 will move due to gravity, and the upper body of the occupant will return to the same vertical position as before. Change the position facing the direction.

At this point, release the pedal 39. The fixed claw 42 engages with the rack 41. In this position the seat 32 is fixed again.

The seat inclination angle can be adjusted frequently according to the vertical movement of the rail.

FIG. 6 shows another embodiment.

Here, there is only one guide rail 30,
Four guide rollers 3 are arranged above and below the guide rail 30.
Since it is sandwiched between four guide rollers 1 and 31, the guide roller 31 rolls along the arc of the guide rail 30.

In the above example, the guide roller 31 was fixed to the seat 32 and the guide rail 30 was fixed to the vehicle frame 25.

However, this relationship may be the opposite.

The guide rail 30 and the seat 32 may be combined, and the guide rollers 31, . . . and the vehicle frame 25 may be integrally combined.

In any case, the fact remains that the seat 32 rotates around the center point O.

(G) Structure of the vehicle frame The structure of the vehicle frame of the passenger trolley 2 will be explained with reference to FIG. This is similar to the structure of a vehicle frame such as a cart or a power vehicle, and consists of an upper wheel and a lower wheel, with a rail sandwiched between them.

In the case of a cart, two upper wheels and two lower wheels sandwich the rails. The axle is fixed, and bearings are installed between the axle and the wheel.

In the case of a powered vehicle, there are two upper and two wheels,
One of the lower axles becomes the drive shaft. This axle has
The drive pinion is fixed and the lower wheel, which has become an idler, is attached via a bearing.

In this respect, the chassis of a passenger trolley is the same as the chassis of a power vehicle. A pinion is fixed to one of the lower axles. This is not for driving, but for braking.

The vehicle frame 25 has an upper axle 51 passed above both sides of the frame 50, and is fixed at both ends with bolts 52 and 53. The upper wheel 26 is attached to the middle of the upper axle 51 via a bearing 54 .

Positioning is done by a collar fitted onto the axle.

The front axle of the lower axle does not appear in this diagram. This is a shaft that is cantilevered into the frame.
A lower wheel is provided via a bearing. The lower axle is supported on one side by the support column 6 that supports the rail 4.
This is because the rails are connected using a joining fitting, and the sides of the rails must be open.

An axle 60 at the rear of the lower axle is rotatably supported by bearings 61 and 62 with respect to the frame 50.

A lower wheel 27 is attached to the end of the lower axle 60 on the rail side.
is provided via a bearing 63, and is removed by a bolt 64.

An emergency brake drum 65 is inserted into the outer end of the lower axle 60 via a key, and the washer 6
6. It is fixed with bolts 67.

An emergency brake shoe 68 faces the inner peripheral surface of the emergency brake drum 65 with a slight gap therebetween.

When the occupant pulls the handbrake lever 33,
A tensile force is transmitted by the wire cable 34 and the emergency brake shoe 68 expands in diameter. The emergency brake shoe 68 contacts the inner peripheral surface of the brake drum 65 and stops the brake drum 65.

Since the pinion 29 and the emergency brake drum 65 were rotating integrally via the lower axle shaft 60, when the brake drum 65 stops, the pinion 29 also stops. Since the pinion 29 meshes with the rack 5 on the side of the rail 4, the passenger trolley 2 is stopped.

In this example, the pinion 29 and the emergency brake drum 65 are coaxially connected. However, it is sufficient that the two are connected to each other, and there is no problem even if there is a deceleration or speed increase mechanism between them.

Although a dual-off user brake is used as the emergency brake 28 in this example, other brakes may be used.

(h) Effects According to the present invention, (1) Conventionally, it was often dangerous for people to be forced to ride on single-rail transport vehicles that had little room for people to ride. According to this invention, since a passenger trolley is connected to a single-rail transport vehicle, agricultural work can be carried out safely and efficiently. There are seats, so
Less fatigue.

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

(3) The seat's longitudinal inclination is adjusted according to the inclination of the rails, ensuring that the human's upper body is always maintained at or close to vertical, providing a comfortable ride.
