Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle return device, and more particularly to a device for turning and returning a vehicle without stopping it at a small turning radius.

[Conventional technology and its problems]

Conventionally, a vehicle device such as that disclosed in Japanese Utility Model Application Publication No. 59-35160 has been known, but with the vehicle device disclosed in the publication, it is impossible to turn the vehicle sharply with a small turning radius. For example, although the track is circular, if two tracks are brought close together to make the vehicle travel as if on a round trip line, it has traditionally been impossible to make a sharp turn at either end of the track. Ta.

[Means for solving problems]

The present invention forms a return part by curving a track consisting of a pair of left and right rails with a small radius of curvature, and also provides a supporting flat part on the inner side of the inner rail corresponding to the inner side of the return part in a plan view. A plurality of driving tires are disposed in the longitudinal direction between them, and a curved guide plate is disposed in close proximity to an outer rail corresponding to the outer side of the return part, so that the curved guide plate and the outer rail are connected. A curved guiding portion is formed; furthermore, the vehicle has four rails rolling on the left and right pair of said rails.
In addition to the wheels, an auxiliary wheel is provided at a front-rear intermediate position on one side corresponding to the inner side of the return part, and the vehicle rides on the support flat part to serve as a center of rotation. The guide wheel has a sled part on the bottom surface that comes into contact with the curved guide part, and a guided ring that enters between the curved guide plate of the curved guide part and the outer rail and is rotatable about a vertical axis guided by the curved guide part. In the return state, the auxiliary wheel rides on the support plane part, and the two front and rear wheels on one side corresponding to the inside of the return part are separated from the inner rail.

[Effect]

In the return section, the two inner front and rear wheels float in the air, but the middle auxiliary wheel is supported by the support flat section, and the inside of the vehicle is reliably supported.

On the other hand, on the outside of the return part, the guided wheel enters between the curved guide plate of the curved guide part and the outer rail,
The guided wheel is guided by this curved guiding portion,
Prevents the outer wheels from coming off the track.

The sled contacts the drive tires and provides a force for turning the vehicle about the auxiliary wheels on the support plane.

〔Example〕

The illustrated embodiment will be described in detail below.

In Figures 1 and 2, 1 is a track supported by supports 3 at a predetermined height from the ground 2,
Although it is laid in an annular shape when viewed from above, in the illustrated example it is formed into an extremely long and narrow ellipse, and the reciprocating parts are extremely close to each other. Platforms 4, 4 are provided at both ends. The platforms 4, 4 have a landing area 5 and a landing area 6, and as shown in FIGS. 1 and 3, the track 1 consists of a pair of left and right rails 7, 7, and a With a radius of curvature, the track 1 is curved to form a return section 8. 9... are stairs for climbing up and down the platform 5, but if the track 1 is laid on the ground 2 and the platform 4 is at a low place, most or all of them can be omitted. Arrow A indicates the running direction of the vehicle, and when the track is arranged in a plan view as shown in FIG. 1, the vehicle appears to travel back and forth between the platforms 4 at both ends. Of course, the shape of the track 1 in plan view can be freely changed to various other shapes (as long as it is annular), and it is also preferable to arrange the platforms 4 and the return portions 8 at three or more locations.

Therefore, a steel plate is stretched on the inner side of the inner rail 7a corresponding to the inner side of the return portion 8 having a small radius of curvature, or a concrete plate is attached, and the supporting plane portion 10 is constructed as shown in FIG. ,establish. Further, a plurality of drive tires 11 are disposed between the pair of left and right inner and outer rails 7a and 7b of the return section 8, and at positions closer to the outer rail 7b than the center thereof. Further, a curved guide portion 12 is provided in the return portion 8 along the outer rail 7b. That is, the curved guide plate 14 is disposed close to the inner surface 13 of the outer rail 7b, and the curved guide plate 14 and the outer rail 7b form the curved guide portion 12.

As shown in FIGS. 4, 5, and 6, the vehicle 15 includes four left and right wheels 16 rolling on the left and right rails 7, 7, and a return section 8. It has an auxiliary wheel 17 that rides on the supporting plane part 10 as shown in the imaginary line in FIG. 3 and serves as the turning center.

When the right side in the vehicle traveling direction is always on the inside of the return section 8 as shown in FIG. 1, the auxiliary wheel 17 is provided only on the right side as shown in FIG. Further, the auxiliary wheel 17 is provided at an intermediate position between the front and back. Although not shown, if the track 1 has a shape that turns both right and left, a pair of auxiliary wheels 17, 17 may be provided on both left and right sides of the vehicle 15.

The vehicle 15 has a sled part 18 on the bottom surface that contacts the driving tires 11, and has guided wheels 19 guided by the curve guiding part 12 as shown by imaginary lines in FIG. It has... However, if there is only a right turn or a left turn over the entire track 1, only the corresponding side of the four guided wheels 19 provided as shown in the figure is connected to the curved guide plate 14 and the outer rail. 7b

Besides a part of the return section 8, all the guided wheels 19 contact and roll against the inner surfaces of the rails 7, 7, such as I-type, so that the vehicle 15 falls off from the rails 7, 7. prevent.

As is clear from the figure, the guided ring 19 is rotatable around the vertical axis, and has a slightly larger outer diameter than the rail 7b and the curved guide plate 14.
The distance between the two is set (see Figure 3). In the return state shown in FIG. 3, the two front and rear wheels 16, 16 on one side (the right side in the figure) corresponding to the inside of the return section 8 are mounted on the inner rail 7a.
The one auxiliary wheel 17 on the inner side (right side) that remains is supported by the support flat part 10, and the opposite wheels 16 on the outer side (left side) swing their heads as casters and move around the curved outer side. It rolls on the rail 7b. Reference numeral 20 denotes a guide member attached along the outer rail 7b and protruding slightly above the upper surface thereof, and guides the outer wheels 16, 16 as casters.

By the way, in FIGS. 1 and 2, the driving tires 11 are located in the range corresponding to the platform 4 and in the vicinity thereof (including the return section 8).
is provided and brought into contact with the sled portion 18 of the vehicle 15 to
The vehicle has a tire drive range T that allows the vehicle to run at a relatively low speed. Furthermore, a driving traveling member 22 such as a rope 21 or a chain is provided along the track 1 outside the tire drive area T, and the traveling member 22 is driven by a drive source 23 consisting of a stationary electric motor and a speed reducer. The vehicle 15 is caused to travel at a speed greater than the speed of the vehicle 15 in the tire drive range T to form a running member drive range R.

The vehicle 15 is provided with a coupler 24 as shown in FIGS. 6 and 7, which is detachably connected to the running member 22 to pull the vehicle 15 and drive it. In FIG. 7, the drive running member 22 is a rope 21, and the coupler 24 is a rope gripper that holds the rope 21. Specifically, it is a pair of arms 26 that swing around a support shaft 25. , 26, a fluid cylinder 27 connecting one end of the arms 26, 26, and an arm 26,
A gripping portion 28, 2 with a recess attached to the other end of 26
8 constitutes a cord gripping device. In addition, as shown in FIG. 6, the left and right positions corresponding to the drive tires 11,
The left and right positions to which the rope 21 and the coupler 24 correspond are slightly different from each other.

Although not shown in the drawings, if the driving traveling member 22 is a chain, the coupler 24 of the vehicle 15 may be a locking pawl member that removably locks onto the chain.

By the way, as shown in FIG. In the acceleration area 31 immediately after,
A large number of tires 11... can be rotated by independent drive sources and arranged sequentially at a predetermined number of rotations, or divided into an appropriate number of groups and each Each group is driven by an independent drive source, and an appropriate speed change mechanism is added to each tire.
It is preferable to use means such as changing the rotational speed of 1....

In this way, in the running member drive range R, the vehicle travels at a relatively high speed, for example, 1 m/sec to 5 m/sec, and at a relatively low speed, for example, 0.1 m/sec to 0.5 m/sec, in the intermediate low speed getting on/off section 29. Let it be sec-. The boundaries between the traveling member drive range R and the acceleration/deceleration ranges 31 and 30 are set to have substantially the same speed, thereby realizing smooth transfer of the vehicle 15.
