Description

[Detailed Description of the Invention] G) Summary A new passenger trolley is connected between the power vehicle and the loading truck of a single-gauge transport vehicle. The passenger trolley is equipped with a seat on which a person can sit, and is further equipped with a hunt brake. The seat is
It is rotatably suspended from a support on the side of the passenger vehicle. The inclination of the seat can be adjusted in the direction of gravity, this positional relationship can be fixed, and it can be adjusted repeatedly.

(B) Technical field Single-gauge transport vehicles are installed in hilly areas such as tangerine orchards and are used to transport agricultural products, fertilizers, etc. There is only one rail, so it is easy to install. Since it is equipped with a drive mechanism in which the rack and pinion are engaged, 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. Braking systems often include a normal stop brake, a constant speed brake, and 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 brakes may not be applied by a person or 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, no space has been 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 load, unlocks the stop brake, and pulls hard on the engine starting wire to start the engine and start the motor vehicle.

The transport vehicle runs unmanned on rails. At the end point (stopping point), there is a brake bar or a stand 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. Stop the transport vehicle.

The other worker at the end of the line unloads or loads the load, switches gears in the opposite direction, and starts 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. Start the single-rail transport vehicle at the starting point, walk with the transport vehicle to the terminal point, and load and unload the cargo. In other words, one person is always moving along with the single-rail transport vehicle.

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 mole rail.

In fact, there are many people who ride single-gauge transport vehicles, and it would be unrealistic to ban them because they would not be able to do agricultural work without them. Is it prohibited to ride because it is dangerous, or conversely, to make it safe to ride?
All you have to do is create something that is technically complete.

Since people still ride them today, they should make something that they can ride with peace of mind.

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

(1) Prior art and its problems Since it was forbidden for people to ride on single-gauge transport vehicles, there are no single-gauge transport vehicles that are widely known and used by the public. For this reason, there is little technical accumulation.

Although it is just an idea,
No. (released on February 19, 1977), Japanese Patent Publication No. 1983-222
No. 13 (released on February 19, 1977) connects a seat type vehicle for people to ride between the power vehicle of a single-gauge transport vehicle and a trolley (baggage vehicle).

In the former, the seat type and trolley are separate pieces. The latter had a new seat built at the front of the trolley.

Both have two independent brake systems. Even if one brake fails, the other brake can stop the vehicle, which prevents the vehicle from running out of control on steep slopes. In fact, when it comes to single-track transport vehicles running on steep slopes,
Measures to prevent runaway behavior are extremely important.

Single track transport vehicles are used on sloped areas. The angle of inclination to the horizon often reaches 30° and even 45°.

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 is sloped downward or upward,
It is desirable that the seat not follow the inclination of the rail, but always remain approximately horizontal.

National) Technical Issues The following requirements are required for passenger single-rail transport vehicles that carry people.

(]) It is possible to stop and start by the driver's operation.

Even if it goes out of control, it can be stopped.

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

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

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

Problems (1) and (2) can be solved by providing a new brake to the passenger trolley. (3) can be overcome by selecting and adjusting the brake.

Issue (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 wheels of a passenger trolley is fixed, the seat may slide forward due to gravity, especially when going downhill.
I feel like I'm about to fall. When going uphill, your center of gravity will shift to the rear, making you feel like you're going to flip backwards.

The passenger carriage of a single-gauge transport vehicle travels on a track with many ups and downs, like a roller coaster.

However, unlike a roller coaster, the length of the vehicle is not large. Passenger trolleys are short in the front-rear direction, but rather large in the vertical direction. Because it is vertical and unstable, there is a high possibility of it falling over, especially forward or backward.

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

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

e) Structure of the present invention The inventor of the present invention constructed the seat like a swing, with the fulcrum as the center and -
I came up with the idea that it would be nice to be able to move and swing, and also be able to fix it in any position.

For this purpose, two pillars are provided on both sides of the passenger trolley, pointing upwards from the frame, and seats are mounted on the pillars in a V-mounted manner. If this continues, it will simply swing around the fulcrum,
A rack is installed below the seat along an arc, and the
The fixed claws should be engaged.

When you step on the seat adjustment pedal, the fixing claw will detach from the rack.
Seating is free. When the seat adjustment pedal is released, the fixing pawl engages the rack again and the seat is fixed.

The bogie of the single-rail transport vehicle of the present invention includes (1) upper wheels and a lower axle that sandwich the rails from above and below, and (2)
A vehicle frame that rotatably supports the upper and lower axles; (3) left and right columns installed on the vehicle frame and extending upward; (4) a seat rotatably suspended from the columns by pins; and (5) (6) a rack provided in the lower part of the seat in an arc shape centered on a pin; (6) a rack provided in the vehicle frame; (7) a seat adjustment pedal that engages or disengages the fixed claw; (8) a pinion that is fixed to the lower axle of the vehicle chassis and engages with the rack; 9) Consists of an emergency brake equipped with an emergency brake drum installed coaxially with a pinion or via a deceleration/acceleration mechanism, and a handbrake installed on the seat for operating the αO emergency brake.

(Force) 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, and a loading trolley 3.
It is made by connecting. The single rail that supports these consists of a rectangular cross-section rail 4, a rack welded to the side, and a rail 4.
It consists of 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 vehicle body 7 that can be made of aluminum alloy or cast iron.
A lower axle 8 and a lower axle 9 are attached via the axles. The power vehicle 1 further includes a power source such as a fuel tank 10 and an engine 11. Power is centrifugal clutch 1
2. It is transmitted from a pulley, a belt, 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 the mission switching lever 13.

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

A constant speed brake 15 provided on the side of the vehicle body 7 prevents the vehicle from driving out of control due to excessive speed when exiting the vehicle. 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 in the event of an abnormality in which the vehicle speeds up too much when exiting the vehicle, and automatically stops the power vehicle.

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

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 cargo truck 3 are connected by a connecting rod 19°19.

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

The vehicle frame 21 has two lower axles 22 and two lower axles 23 attached to a frame made of aluminum alloy, cast iron, or the like via the axles. The vehicle rack 21 is connected to the loading platform 20 so that it can be turned left, right, up and down.

Even if the rail 4 curves vertically or horizontally, the vehicle frame 21 can turn 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 ilj diagram.

The passenger trolley 3 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 axle 27 that sandwich the rail 4 from above and below. An emergency brake 28 and a pinion 29 connected to the emergency brake 28 and meshing with the rack 5 are provided on one of the lower axles. When the emergency brake 28 is activated, the pinion 29 is stopped and the passenger trolley 2 is stopped.

A bottom plate 30' and pillars 30, 30 integrally formed on the sides of the bottom plate 30' are provided above the vehicle frame 25.

There are pins 31 and 31 on the upper left and right sides of the pillar, and seat 3
2 is swingably suspended from a pin 31.

The seat 32 has a backrest and a horizontal plate, but as a whole it is only swingably supported by pins 31,31.

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

A ratchet 35 is fixedly installed 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. By pressing the lever button 33', 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 the lever 33 is pulled up, the limit switch 36 is actuated by the lever. The on/off signal from the switch 36 is transmitted through the engine stop cord 31 to stop the engine 11 of the power vehicle 1.

After the engine stops, the emergency brake 28 starts to apply, the pinion 29 stops, and a braking force is generated on the passenger trolley 2. In this way, the entire transport vehicle can be stopped.

The seat 32 can swing back and forth around the pin 31. When a person is seated on the seat 32, the center of gravity is at the pin 31.
The height of the seat and backrest are set so that it is directly below the seat.

It would be dangerous if the seat were to constantly swing, so a fixing mechanism or a separate fixing mechanism should be provided.

A seat adjustment pedal 39 is provided at the lower front of the passenger trolley 2 at a position where it can be stepped on with the foot.

On the other hand, an arcuate rack 41 centered around the pin 31 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. seat 32
The angle of inclination with respect to the vehicle frame 25 and the support column 30 is fixed.

When the seat adjustment pedal 39 is stepped on, the fixed pawl 42 is lowered and the rack 41 is released. The seat 32 swings freely relative to the column 30. Since the center of gravity, including the human body, is set to be directly below the pin 31, if the occupant's posture is correct, the seat 32 will move due to gravity, and the human's upper body will be in a position facing the same vertical direction as before. Changes to At this point, release the pedal 39. The fixed claw 42 engages with the rack 41. In this position the seat 32 is re-secured.

It is easy to adjust the seat inclination angle according to the vertical movement of the rail.

i) 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 truck or a power vehicle.
It consists of an upper wheel and a lower axle, with a rail sandwiched between them.

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

In the case of a motor vehicle, there are two upper and lower wheels, or one of the lower axles is the drive shaft. A drive pinion is fixed to this axle and is attached to the loose lower axle 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 a lower axle 51 passed above both sides of the frame 50, and is fixed at both ends with poles 52 and 53. The upper wheel 26 is attached to the middle of the stop shaft 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 cantilever-supported by the frame, and a lower axle is provided via a bearing. The reason why the lower axle is supported on one side is because the support column 6 that supports the rail 4 and the rail are connected by a coupling fitting, and the sides of the rail must be open.

The rear axle 60 of the lower axle is driven by bearings 61,62.
It is rotatably supported by the frame 50.

The lower axle 27 has a bearing 6 at the end of the lower axle 60 on the rail side.
3 and is removed by a bolt 64.

An emergency brake drum 65 is attached to the outer end of the lower axle 60.
is inserted through the key, washer 66 and bolt 67
Fixed by

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

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

The pinion 29 and the emergency brake drum 65 are connected to the lower axle 60
Since the pinion 29 rotates integrally with the brake drum 65, when the brake drum 65 stops, the pinion 29 also stops. Since the pinion 29 meshes with the rack 5 on the surface 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 an intermittent reduction or speed increase mechanism is interposed.

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

(ri) Effects According to the present invention: (1) Conventionally, it was often dangerous to force people to ride on a single-rail transport vehicle, which 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 there is 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, so that the human's upper body is always held vertically or in a state close to vertical, so the ride is comfortable.
