Description

A Ferris wheel that moves along the outer circumference of a circular tower where a boarding car is fixed {FERRIS WHEEL HAVING PASSENGER CAR MOVING ALONG OUTER CIRCUMFERENCE SURFACE OF FIXED CIRCLE-TYPE TOWER}

The present invention relates to a Ferris wheel installed outdoors at a tourist attraction or amusement park so that passengers can enjoy the surrounding scenery. More specifically, the lower part of the circular tower is stably fixed on the ground and a radial wheel is installed inside the circular tower. By eliminating the need to install reinforcing structures, the impact of strong winds is minimized, and by allowing the boarding car to move in an arc along the outer circumference of the fixed circular tower, it prevents the viewer's view from being blocked by the circular tower structure, creating a beautiful appearance and It's about a Ferris wheel that improves the view.

In general, a Ferris wheel consists of a plurality of riding cars suspended around a large circular rotating wheel, and is installed outdoors in tourist attractions or amusement parks.

When the rotating wheel of the Ferris wheel of the above structure rotates at a low speed, the plurality of passenger cars hanging on the rotating wheel also rotate, allowing passengers in the passenger cars to view the surrounding scenery.

An example of such a Ferris wheel is the “Amphibious Ferris Wheel” of Korean Patent No. 10-2110937.

As shown in FIGS. 1 and 2, the conventional large Ferris wheel includes a plurality of support frames 100, one end of which is fixed to the sea floor; A rotating wheel (200) whose central part is coupled to the other end of the support frame and rotates by power; A plurality of gondolas (300) arranged at regular intervals on the outer peripheral surface of the rotating wheel and moving according to the movement of the rotating wheel; and a power generation unit 400 that generates power to rotate the rotating wheel.

In addition, the rotating wheel 200 has a certain lower portion located lower than sea level, and the gondola 300 has an interior angle 310; an outer shell 320 that is spaced apart from the outer peripheral surface of the inner shell 310 at a predetermined distance and is provided to surround the inner shell; A ballast tank (330) formed between the inner shell and the outer shell, through which seawater is mainly drained when the gondola enters and exits the water. and a compressed air tank 340 provided on the outer peripheral surface of the interior cabinet to supply compressed air to the ballast tank and the interior cabinet, respectively.

In Figures 1 and 2, reference numeral 110 indicates a vibration isolation member, and 230 indicates a gondola support.

According to the conventional amphibious Ferris wheel shown in Figures 1 and 2, the gondola (boarding car) moves sequentially through the water and underwater by the rotation of the rotating wheel, so that the passengers on the gondola can enjoy only the natural environment of the water. Instead, you will be able to view the underwater marine environment sequentially.

However, in the conventional Ferris wheel shown in FIGS. 1 and 2, a plurality of members connecting the power generating unit 400 and each gondola 300 are provided radially inside the rotating wheel 200.

Accordingly, there is a disadvantage in that the wind load due to the wind increases.

In addition, since the structure rotates a large rotating wheel 200, there is a disadvantage that a large driving force is required, thereby increasing the size of the power generation unit 400.

Additionally, since each gondola 300 is connected to the rotating wheel 200 by one support shaft, there is a problem in that the boarding compartment is shaken by vibration and impact.

As a result, it is greatly affected by the wind, and even a slight breeze makes driving difficult.

In order to solve the above problems, a "large Ferris wheel with improved stability by strengthening the bearing capacity of the passenger compartment" has been proposed in Korean Patent No. 10-2329453.

As shown in FIGS. 3 to 5, the conventional large Ferris wheel includes a support 2 having one end fixed to the ground and including pillars installed upward; A rotating shaft (3) installed on top of the pillars and installed horizontally with the ground; A rotating part (4) rotatably installed on the rotating shaft and including a pair of rotating bodies in which a plurality of support parts are installed at intervals in the circumferential direction on an inner surface that faces each other; It is formed in a cylindrical shape, has a boarding space inside for passengers to board, and includes boarding compartments 5 installed on both sides to be supported by supports of the rotating part.

And the rotating part 4 includes a pair of rotating bodies 41 installed in parallel and spaced apart from each other, and the rotating body is formed in a disk shape and has a shaft insertion hole in the center into which the rotating shaft 3 is inserted. A circular frame 411 is formed; Frames 412, one end of which is coupled to the outer peripheral surface of the circular frame, are installed radially from the circular frame; An inner ring frame (413) formed in a ring shape, where the outer ends of the frames are coupled to the inner peripheral surface; an outer ring frame 414 formed in a ring shape, having a larger diameter than the inner ring frame, and disposed outside the inner ring frame; A plurality of connection frames 415 connecting the inner ring frame and the outer ring frame; It is configured to include support portions 416 installed at intervals in the circumferential direction on the inner surfaces of the inner ring frame and the outer ring frame.

And the support portions 416 include a side support plate 4161 that is formed in the shape of a hollow disk and has one side coupled to the inner side of the inner ring frame and the outer ring frame; It is formed in a hollow cylindrical shape and protrudes from the other side of the side support plate, and includes a hollow cylindrical portion 4162 with a bearing installed on the inner circumferential surface and rotatably coupled to the passenger compartment.

According to the conventional large Ferris wheel shown in FIGS. 3 to 5, both sides and the outer peripheral surface of the passenger compartment are supported by supports installed on the rotating part, thereby increasing the support force of the passenger compartment.

This has the advantage of preventing the passenger compartment from rotating in an abnormal direction or being separated from the rotating part even when external shocks and vibrations are applied to the passenger compartment, thereby preventing personal accidents from occurring.

In addition, since both sides of the boarding compartment are configured to be in contact with the support frames and balls, not only is the lateral movement of the boarding compartment restricted by the supports, but it is also possible to reduce friction and noise generated when rotating due to contact with the balls. There is an advantage to having it.

However, the conventional large Ferris wheel shown in Figures 3 to 5 also has a disadvantage in that it requires a large driving force because it has a structure that rotates a huge rotating wheel.

In addition, since a number of reinforcing members are provided radially inside the rotating wheel, it is greatly affected by wind pressure and operation must be stopped even when a weak wind blows to prevent accidents.

In addition, since the boarding car is surrounded by a rotating structure, it has the disadvantage of impeding the view of the audience and reducing the sense of view.

It is comprised of a hydraulic cylinder 19 connecting the sheave 17 and the driven sheave 18 on both sides, and a spring 19a provided on the outer peripheral surface of the piston of the hydraulic cylinder 19.

The hydraulic cylinder 23 serves to increase the friction between the traction sheave 17 and the wire rope 13 by pushing the driven sheave 18 at a constant pressure.

As a result, it is possible to maintain a constant tension at all times without causing slip in the wire rope 13.

Meanwhile, in the drawing, the wire rope 13 is shown as having 5 strands, but the number of wire rope strands can be adjusted appropriately depending on the weight of the passenger car 12.

And, as shown in FIG. 11, one end of the first wire rope 13' is fixed to the first wire rope first fixing part 13c of the first boarding car 12', and the other end is fixed to the second wire rope first fixing part 13c. It is fixed to the first wire rope second fixing part 13d of the boarding car 12".

And one end of the second wire rope (13") is fixed to the first second wire rope fixing part (13a) of the first boarding car (12'), and then the traction sheave (17) → driven sheave (18) → After being sequentially wound on the traction sheave (17), the other end is fixed to the second wire rope second fixing part (13b) of the second boarding car (12").

According to the wire rope roping method described above, when the traction sheave 17 is rotated clockwise, the first boarding car 12' connected to the first wire rope 13' rotates clockwise.

Then, the first boarding car (12') and the second boarding car (12") connected by the second wire rope (13") also rotate clockwise.

As a result, the first boarding car 12' and the second boarding car 12" can be moved along the outer peripheral surface of the circular tower 11 at the same time.

In addition, as shown in FIG. 10, the first boarding car 12' and the second boarding car 12" are in contact with the inner circumference of the circular frame 12a when moving along the outer circumferential surface of the circular tower 11. The internal roller 12d provided on the outer peripheral surface of the car body 12b and the weight member 12e provided on the lower surface of the boarding car body 12b maintain a horizontal state at all times.

In the present invention, as shown in FIGS. 9 and 12, wire rope guide rollers 13e for guiding the wire rope 13 are arranged horizontally at regular intervals around the outer peripheral surface of the circular tower 11. do.

In addition, although not shown in the drawing, a portion of the lower portion of the circular tower 11 may be buried in the ground without separately installing a structure to support the circular tower 11 at the bottom. In this case, a pit is formed in the ground to allow the boarding car 12 to pass through.

Additionally, in the present invention, as shown in FIG. 6, an emergency exit 20 is provided at the top of each boarding car.

This allows passengers in the boarding car to be safely rescued in the event of an emergency.

Hereinafter, the operating process of the Ferris wheel according to the present invention will be described with reference to FIGS. 10 and 11. For convenience, the case where there are two boarding cars is used as an example.

When a passenger calls a boarding car from the lower platform 16, boards the first boarding car 12', and rotates the traction sheave 17 clockwise, the first boarding car 12' rotates clockwise. While doing so, you will go up to the left side of the circular tower (11).

At this time, the boarding car rises while maintaining a horizontal state due to the internal rollers 12d and the weight member 12e provided radially on the boarding car.

When the first boarding car 121 reaches the sky lounge 14 at the top, passengers who want to get off at the sky lounge 14 get off.

At this time, the second boarding car 12" reaches the lower platform 16, so new passengers can board the second boarding car 12".

Then, when the traction sheave (17) is driven counterclockwise, the first boarding car (12') rotates counterclockwise and reaches the lower platform (16) again, and the second boarding car (12") is the sky lounge. Reach (14) and let passengers who want to get off get off.

That is, when there are two boarding cars, the first boarding car (12') goes up and down only on the left side of the circular tower (11), and the second boarding car (12") goes up and down only on the right side of the round tower (11). .

In addition, the present invention allows the traction sheave 18 to be operated only when both the passenger car doors 12c of the first boarding car 12' and the second boarding car 12" are closed. As a result, safety accidents are prevented. occurrence can be prevented.

In the Ferris wheel according to the present invention, unlike the conventional Ferris wheel that rotates the circular tower, the ring-shaped circular tower 11 maintains a fixed state, and the boarding car 12 moves along the outer peripheral surface of the circular tower 11. Move in an arc.

As a result, the view of the passenger in the boarding car is not blocked by the circular tower structure, thereby improving the passenger's view and satisfaction.

Additionally, there is a sky lounge made of transparent material at the top of the circular tower, so passengers can get off at the sky lounge and slowly enjoy the surrounding scenery if they wish.

Additionally, since there is no structure supporting the inside of the circular tower, the influence of wind load can be minimized, the number of working hours can be reduced, and the aesthetics of the Ferris wheel can also be improved.

Additionally, since the influence of wind load is reduced, the circular tower can be made very large.

In addition, since the passenger car is driven by wire rope, the structure of the driving part is simplified and maintenance is also simplified.

In particular, when only two passenger cars are installed, one serves as a counterweight to the other, so the traction sheave can be driven with very little force. This can reduce Ferris wheel operating costs.

In addition, since each boarding car is supported by four rollers and each roller moves in an arc along the groove of the guide rail, the boarding car can be moved stably.

In addition, a plurality of boarding car internal rollers 12d are provided between the inner peripheral surface of the circular frame 12a and the outer peripheral surface of the boarding car body 12b, and a weight member 12e is provided on the inner surface of the boarding car body 12b. , the boarding car body can always be maintained in a horizontal state when moving along the outer circumference of the circular tower (11).

In addition, since a damper 12j is provided to increase friction on the outer peripheral surface of the boarding car body 12b in contact with the boarding car internal roller 12d, shaking due to wind, etc. when the boarding car moves can be minimized.
