JP 2000-203419 A

  In the single rail conveyor, a plurality of pairs of upper and lower wheels that roll along the upper surface and the lower surface of the rail are arranged in a single wheel unit at intervals in the direction in which the rail extends. For this reason, in the single rail transport device, when the carriage moves along a rail having a large curvature and a radius of curvature smaller than a predetermined radius of curvature, the flanges provided on both sides in the axial direction of the wheel continue to contact the rail. It will be in a state and it will be in the state where the wheel was caught with respect to the rail. For this reason, in the said single rail conveyance apparatus, since a rail will be shaved by a flange when a rail with a small curvature radius is installed, there exists a possibility that durability may deteriorate.

  An object of the present invention is to provide a single rail transportation device that can prevent deterioration of durability and can be installed with a rail having a small radius of curvature.

  In order to achieve the above-mentioned object, the present invention is a single-rail transport device having a carriage that moves along a single rail, provided on both sides of the traveling direction of the bottom surface of the carriage, with respect to the bottom surface of the carriage. The wheel unit has a first wheel that rolls along the upper surface of the rail, and a second wheel that rolls along the lower surface of the rail. One first wheel and one second wheel are in contact with the rail.

  Thus, when the carriage moves along a curved rail, each wheel unit rotates in accordance with the curvature of the rail, and in each wheel unit, one wheel is provided for each of the upper and lower surfaces of the rail. Therefore, the carriage can move along a rail having a large curvature with a small radius of curvature without causing a catch between the wheel and the rail.

  According to the present invention, the carriage can be moved along a large-bending rail having a small curvature radius without causing a catch between the wheel and the rail, so that the curvature can be reduced without deteriorating the durability. It becomes possible to install a rail with a small radius.

  1 to 3 show an embodiment of the present invention.

  The single-rail transportation device 1 of the present invention is provided, for example, between a doorway of a house built on an inclined land and a road, and transports a person using the house between the entrance of the house and the road. is there. As shown in FIG. 1, the single rail transport device 1 includes a track 10 installed on the ground between a doorway of a house and a road, and a transport vehicle 20 that moves along the track 10.

  The track 10 includes a rail 11 as a rail for guiding the transport vehicle 20 and a plurality of support columns 12 that support the rail 11 with an interval upward from the ground.

  The rail 11 is configured by connecting a plurality of cylindrical members having a rectangular cross section. A rack gear 11 a is provided on the lower surface of the rail 11. The rail 11 is bent according to the state of the land to be installed and the path of the track.

  The support | pillar 12 consists of a cylindrical member with a circular cross section. The support column 12 is fixed to the ground by driving the lower end side into the ground, and the rail 11 is fixed to the upper end side via a mounting bracket 12a.

  The transport vehicle 20 includes a carriage 30 that travels along the rails 11 and a pair of seats 40 that are provided on the upper surface of the carriage 30 and on which passengers sit.

  The cart 30 includes a frame 31 formed in a rectangular shape and a pair of wheel units 32 provided on both sides of the lower surface of the frame 31 in the traveling direction of the cart 30. The pair of wheel units 32 are disposed, for example, at an interval of 70 cm from each other.

  The wheel unit 32 includes a wheel support member 32a extending downward from the lower surface of the frame 31, a first wheel 32b rotatably supported above the wheel support member 32a, and a wheel support member 32a rotatably supported below the wheel support member 32a. Second wheel 32c.

  The wheel support member 32 a is a plate-like member extending in the vertical direction, and is supported by the frame 31 so as to be rotatable about a direction orthogonal to the lower surface of the frame 31.

  The first wheel 32b is made of a member having a circular cross section provided with flanges 32d on both sides in the axial direction. In the state where the flange 32 d is adjacent to the outer side in the width direction of the rail 11, the first wheel 32 b is in contact with the upper surface of the rail 11 and rolls with respect to the upper surface of the rail 11.

  The second wheel 32c is a pinion gear provided with teeth that mesh with the rack gear 11a of the rail 11 on the outer peripheral portion. Flange 32e is provided on both sides in the axial direction of second wheel 32c, and rail 11 is located between each flange 32e.

  The second wheel 32c of one wheel unit 32 functions as a drive wheel. As shown in FIG. 3, an electric motor 33 is connected to the second wheel 32 c that functions as a driving wheel, and is driven by receiving the rotational force of the electric motor 33. The electric motor 33 is driven by, for example, power from a single-phase AC 100V power source (not shown) or battery (not shown). The driving state of the electric motor 33 is switched by the occupant operating the operation input unit 34 including an operation lever and an operation button provided near the seat 40.

  The pair of seats 40 are arranged side by side in the traveling direction of the carriage 30 and are directed to the side with respect to the traveling direction of the carriage 30. In other words, the occupants seated in each of the pair of seats 40 are in a side-by-side state in a state of being sideways with respect to the traveling direction of the carriage 30.

  In the single-rail transport device 1 configured as described above, the transport vehicle 20 moves along the rail 11 when the operation input unit 34 is operated while the occupant is seated on the seat 40 and the electric motor 33 is driven. At this time, when the second wheel 32c of one wheel unit 32 connected to the electric motor 33 rotates, the second wheel 32c of the other wheel unit 32 and the first wheel 32b of both wheel units 32 are Roll on top or bottom.

  Further, when the transport vehicle 20 moves on the curved rail 11, each wheel unit 32 rotates with respect to the frame 31 of the carriage 30 according to the curvature of the rail 11. In each wheel unit 32, one first wheel 32 b is disposed on the upper side of the rail 11, and one second wheel 32 c is disposed on the lower side of the rail 11. Thereby, in each wheel unit 32, only one first wheel 32b and one second wheel 32c are in contact with the rail 11. For this reason, the transport vehicle 20 moves along the rail 11 without the flange 32d of the first wheel 32b and the flange 32e of the second wheel 32c being caught by the rail 11 having a large bend. Here, the radius of curvature of the rail 11 to which the transport vehicle 20 can move is a radius of curvature that is about 1.5 times the interval between the pair of wheel units 32 (for example, when the interval between the pair of wheel units 32 is 70 cm, A radius of curvature of 105 cm).

As described above, according to the single rail transportation device of the present embodiment, the wheel unit 32 that is provided on both sides in the traveling direction of the carriage 30 and is rotatable around the direction orthogonal to the lower surface of the frame 31 of the carriage 30 is provided. The wheel unit 32 includes a first wheel 32b and a second wheel 32c that roll along the upper surface and the lower surface of the rail 11, respectively, and only the first wheel 32b and the second wheel 32c are in contact with the rail 11. Yes.
Thereby, the carriage 20 can be moved along the rail 11 having a large curvature radius and a small curvature radius without causing a catch between the first wheel 32b and the second wheel 32c and the rail 11. It is possible to install a track with a small radius of curvature without deteriorating durability.

The rail 11 is provided with a rack gear 11a on the lower surface, and the second wheel 32c is a pinion gear that meshes with the rack gear 11a.
Thereby, since the rotational force of the electric motor 33 can be reliably transmitted to the rail 11, the transport vehicle 20 can travel regardless of the inclination angle of the rail 11.

  4 to 7 show another embodiment of the present invention. In the present embodiment, the same components as those in the above embodiment are denoted by the same reference numerals.

  As shown in FIG. 4, in the single rail transport device 1, a frame 31 of a carriage 30 is provided with one wheel unit 32, and a first frame 31 a positioned on one side in the traveling direction of the transport vehicle 20 and the other wheel. The unit 32 is provided and has a second frame 31b located on the other side in the traveling direction.

  The first frame 31a is formed such that the length dimension in the traveling direction of the transport vehicle 20 is larger than that of the second frame 31b. The pair of seats 40 is attached to the first frame 31a.

  The first frame 31 a and the second frame 31 b are connected to each other in a substantially central portion in the width direction via a support shaft 31 c that extends in the traveling direction of the transport vehicle 20.

  In addition, the single rail transport device 1 has a wheel support member 32g of the wheel unit 32 supported by the frame 31 so as to be rotatable about a direction orthogonal to the lower surface of the frame 31, as shown in FIGS. As described above, the first wheel 32b and the second wheel 32c are provided so as to be freely slidable through the support shaft 32h in a direction perpendicular to the axial direction.

  In the single rail transport device 1 configured as described above, in a portion that is curved in the vertical direction so that the rail 11 projects upward or downward, the direction orthogonal to the lower surface of the frame 31 and the direction in which the rail 11 extends. In some cases, the direction perpendicular to the vertical direction differs from the vertical direction.

  When the transport vehicle 20 moves on the rail 11 curved in the vertical direction, as shown in FIGS. 6 and 7, the wheel support member 32 g extends with respect to the carriage 30 according to the curvature of the rail 11. Swing in the direction. For this reason, in each wheel unit 32, the 1st wheel 32b and the 2nd wheel 32c which are located in the up-down direction both sides of the rail 11 do not be in the state pushed by the rail 11 to the up-down direction both sides, respectively. Thereby, the transport vehicle 20 moves on the rail 11 without generating resistance between the wheel unit 32 and the rail 11.

In addition, when the rail 11 is extended along the direction in which the slope is inclined and the tip of the rail 11 is bent in a direction perpendicular to the direction of inclination, in order to prevent the width of the transport vehicle 20 from being inclined, On the other hand, a twisting process for twisting the rail 11 extending in a direction orthogonal to the rail 1 extending in the inclined direction is performed.
When the transport vehicle 20 moves on the rail 11 on which the twisting process is performed, the second frame 31b rotates with respect to the first frame 31a. Thereby, the transport vehicle 20 moves smoothly on the rail 11 without generating resistance on the rail 11 on which the torsion processing is performed.

  As described above, according to the single rail transportation device of the present embodiment, as in the above-described embodiment, the first wheel 32b and the second wheel 32c and the rail 11 are not caught and the radius of curvature is reduced. Since the transport vehicle 20 can be moved along the small rail 11 with a large bend, it is possible to install a track with a small curvature radius without deteriorating durability.

Each wheel unit 32 is provided so as to be swingable in a direction perpendicular to the horizontal direction with respect to the axial direction of the first wheel 32b and the second wheel 32c.
Thereby, when the transport vehicle 20 moves on the rail 11 that is curved in the vertical direction, the wheel support member 32g swings in the extending direction of the rail 11 in accordance with the bending of the rail 11 with respect to the carriage 30. The transport vehicle 20 can be moved along the rail 11 without causing resistance between the wheel unit 32 and the rail 11.

The frame 31 of the carriage 30 is provided with a first frame 31a provided with one wheel unit 32 and the other wheel unit 32, and is rotatable with respect to the traveling direction of the carriage 30 with respect to the first frame 31a. And a second frame 31b connected to each other.
Thereby, when the transport vehicle 20 moves on the rail 11 having torsion, the second frame 31b rotates with respect to the first frame 31a, so that resistance is generated between the wheel unit 32 and the rail 11. The transport vehicle 20 can be moved along the rail 11 without being generated.

  In the above embodiment, the transport vehicle 20 is driven by the electric motor 33. However, the transport vehicle may be driven by the power of the engine.

  Moreover, although the thing which provided the 2nd wheel 32c driven by the electric motor 33 in the transport vehicle 20 was shown in the said embodiment, it is applicable also to the transport vehicle which does not have the drive wheel which can be pulled with a tow vehicle. .

  Moreover, in the said embodiment, although the thing which provided the seat 40 in the trolley | bogie 30 and moved a person was shown as the transport vehicle 20, it is not restricted to this. For example, a loading platform may be provided on the cart 30 to transport items such as agricultural products.

  Moreover, in the said embodiment, although the rack gear 11a was provided in the rail 11 and the 2nd wheel 32c was made into the pinion gear, what showed the rotational force of the electric motor 33 to the rail 11 was shown, It is not limited. For example, the rotational force of the electric motor 33 is transmitted to the rail 11 by generating a large frictional force between the rail 11 and the second wheel 32c without using a pinion gear as the rack gear 11a and the second wheel 32c. You may do it.

  In the above embodiment, the flange 32d of the first wheel 32b and the flange 32e of the second wheel 32c are positioned on both sides in the width direction of the rail 11, thereby preventing the carriage 20 from falling off the rail 11. However, the present invention is not limited to this. For example, a rail having grooves formed on the upper surface and the lower surface, and a first wheel and a second wheel that do not have the flanges 32d and 32e, and moving the first wheel and the second wheel in the rail groove, You may make it prevent dropping of the transport vehicle 20 with respect to a rail.

  Moreover, in the said embodiment, it has twist by the frame 31 which has the 1st flame | frame 31a and the 2nd flame | frame 31b connected with respect to the 1st flame | frame 31a centering | focusing on the advancing direction of the trolley | bogie 30. Although what was made to move on the rail 11 smoothly was shown, it is not restricted to this. For example, even if at least one of the pair of wheel units 32 is provided so as to be freely slidable in the axial direction of the first wheel 32b and the second wheel 32c, the same effect as in the above embodiment can be obtained.
