Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a Ferris wheel drive device for a Ferris wheel installed in an amusement park, etc., for enjoying the view from a high place while riding on a rotating gondola. .

[Problems that conventional technology and ideas try to solve]

A conventional drive device of this type has a circular rail attached to a rotary wheel on which a large number of gondolas are disposed, and a drive wheel that presses the rail from the inside and outside to roll, and the drive wheel moves along the circular rail. The rotary wheel was rotated by the rotational driving force applied to the rotary wheel. However, since the drive wheel has a structure that is directly fixed to a support frame etc. that pivotally supports the rotating wheel, if there is a distortion in a part of the circular track, the drive wheel and the track may be subjected to excessive pressure. Because of the contact caused by pressure or the occurrence of slipping, problems have arisen in that distortion of the rail cannot be absorbed or that a predetermined rotational driving force cannot always be applied.

The present invention relates to a Ferris wheel driving device for solving the above problems.

[Means to solve the problem]

In the present invention, a rotating ring is rotatably supported around a horizontal axis by a support frame, a plurality of gondolas are arranged on the outer circumferential side of the rotating ring, and a circular rail is provided on the rotating ring. In a Ferris wheel driving device for a Ferris wheel having: one end is pivotally supported by a fixed member such as the support frame, and the other end is swingable in and out of the rail about the one end. a frame body; an inner drive wheel holder attached to the frame body so as to be adjustable in the inner and outer directions and disposed on the inside of the rail; an outer drive wheel holder disposed; a holding member that connects the outer drive wheel holder and the inner drive wheel holder to maintain a predetermined distance between the holders; the inner drive wheel holder; an inner drive wheel that is attached to the outer drive wheel holder and presses and rolls the rail from the inside to apply rotational driving force to the rotating wheel; an inner drive wheel that is attached to the outer drive wheel holder and presses and rolls the rail from the outside; and an outer drive wheel that applies rotational driving force to the rotating wheel.

[Effect]

Since the inner drive wheel holder and the outer drive wheel holder can be adjusted in the outward and outward directions of the rail, by adjusting their inner and outer positions, the inner and outer drive wheels can be pressed against the rail with a predetermined pressing force. Moreover, since the distance between the inner and outer drive wheels is maintained constant by the holding member, rotational driving force can be reliably applied to the rotating wheel, and the rotating wheel rotates.

Moreover, since the frame body pivots in the inward and outward directions with one end thereof as the center, the other end thereof swings in the inward and outward directions, so even if the circular rail is distorted, each drive wheel can swing in the inward and outward directions together with the frame body.

It is elastically biased upward by support members 25... having 2.... The supporting members 25 also act to damp the vibrations of the mounting frame 12 during operation, and are fixed on a mounting base 23 that is a part of the fixed member 11 and extends horizontally. Above mounting member 2
A long hole 30 is formed in the drive wheel holder 21a, 21b, and the distance between the motors 13 connected and fixed to the drive wheel holders 21a and 21b can be adjusted. The distance L between the rings 10a and 10b in the inner and outer directions can be adjusted to the dimensions of the circular rail 7. 24... connects the inner drive wheel holder 21a and the outer drive wheel holder 21b to connect the holder 21.
This is a holding member (tie rod) that holds the wires a and 21b at a predetermined distance, and is used for adjustment by bringing them into contact with the rail 7 with an appropriate pressing force. Note that the bolts connecting the two members 20, 20 are not shown.

27... is a lateral vibration prevention member, and as shown in FIG. To improve riding comfort by preventing a rotating wheel 2 from shaking in the lateral direction with respect to a center 4, or by preventing small shaking of the rotating wheel 2.

By rotating the motor 13 in the direction of the arrow C, the circular rail 7 is provided with drive wheels 10a, 1.
A rotational driving force is applied around the horizontal axis 4 in the direction of arrow D through the drive wheels 10a, 10b...

Excessive contact force may be generated between the and the circular rail 7,
The driving wheels 10a, 10b, . . . do not have any problems such as slipping, and the driving wheels 10a, 10b, .

In the above embodiment, a plurality of pairs of inner and outer drive wheels 10a, 10b, . . . are provided on the mounting frame 12, but only one pair may be provided. The fixing member 11 is provided separately from the support frame 3, but unlike this, if the mounting frame 12 is swingably provided on the support frame 3, that is,
It is also preferable that the support frame 3 also serves as the fixing member 11. Note that vibration-proof rubber may be used for the elastic members 22.

[Effect of idea]

Since the present invention is constructed as described above, it produces the following effects.

The inner drive wheel 10a and the outer drive wheel 10b can each be pressed against the rail 7 with an appropriate pressing force,
Moreover, the distance L between the inner and outer drive wheels 10a and 10b
can be held constant, a predetermined rotational driving force can be reliably applied to the rail 7, and the rotating wheel 2 can be rotated without slipping or the like.

Since rotational driving force is applied to the rail 7 from both the inside and outside, there is no need to increase the pressing force from the inside or from the outside, and there is no need to increase the pressing force from the inside or the outside. does not work, resulting in excellent durability.

Even when the rail 7 is in a distorted shape, the inner and outer drive wheels 10a and 10b apply appropriate pressing force to the rail 7 while maintaining the frame body 17.
The rails 7 swing inward and outward directions in accordance with the shape of the rails 7, and a predetermined rotational driving force is always applied to the rails 7, so that the rotating wheels 2 and, in turn, the gondolas 5 rotate smoothly.
