Description

The invention relates to an attraction with a fixed load-bearing structure, on which transport means for visitors are circulating, and with a cable drive for transport means.
An attraction of this type is known from EP A 459 789. The cabs are driven by two endless power ropes, which are driven by a motor. The disadvantage of this embodiment is that the synchronization of both separate rope loops can only be ensured with very high technical costs, since it is not sufficient to ensure the rotation of both drives with the same rotation speed, since small differences in diameter, respectively, of the circumference of the drive pulleys can lead to different speeds of transportation of both rope loops.
Therefore, the basis of the invention is the task of creating a drive for an attraction of the specified type, which ensures synchronized movement of both rope loops.
This problem is solved in the attraction of the indicated type by the fact that a single closed traction rope is provided, which, when crossed through a device for changing the direction of movement, forms two rope loops acting on transport vehicles.
Since the invention provides only one endless rope, which is laid with two loops around the supporting structure and connected to the transport means, synchronous running of both rope loops is automatically ensured.
When connecting both rope loops with vehicles, two embodiments are preferred.
One embodiment is characterized in that the traction rope acts on the conveyance means through a friction closure connection and that at least one rope roller rests on the conveyance means on which the traction rope rests. In this embodiment, the connection is made very simple, since it is realized only due to friction due to the tight fit of the traction rope to the corresponding contact area of the vehicle, in particular to its cart.
Another preferred embodiment is characterized in that the traction rope is connected to the transport means by means of detachable clamps. This embodiment provides an even stronger connection between the conveyor and the traction rope, however, with higher technical costs for detachable clamps.
As for the device for changing direction and the drive for the rope, according to the invention, essentially two options are preferred.
For both embodiments, it is common that the device for changing the direction of movement has two drive pulleys located coaxially adjacent to each other, and two guide rollers mounted next to each other are provided at the input and output of the specified device.
The first embodiment is characterized in that the drive pulleys are driven in opposite directions and that the guide rollers are mounted with axes parallel to each other.
The second embodiment is characterized in that the drive pulleys are driven in the same direction, while one pair of guide rollers is mounted with coaxial axes, the other pair of guide rollers are mounted with axes tilted to each other, and a guide device is located in the area of this other pair of guide rollers and the loops of the rope cross each other between the guide device and this other pair of guide rollers.
Other preferred embodiments of the invention are disclosed in the remaining dependent claims.
The invention is further explained in the description of the options for its implementation with reference to the accompanying drawings, including:
figure 1 depicts an example implementation of the attraction according to the invention in an oblique projection;
figure 2 - zone of embarkation and disembarkation of the attraction, under which there is a drive, on an enlarged scale;
figure 3 - the first embodiment of the connection of the traction ropes with cabs;

figure 5 - drive attraction on an enlarged scale;
Fig.6 - the passage of the rope in the area of the drive according to Fig.5;
7 is an alternative embodiment of a drive; and
Fig.8 is the passage of the rope in the area of the drive according to Fig.7.
Figure 1 shows in oblique projection an attraction according to the invention, which is usually called a Ferris wheel. The attraction has a fixed, rigid load-bearing structure 1, which is made, for example, in the form of a reinforced concrete ring, on which transport vehicles in the form of cabs make a circular motion. The outer surface 4 of the supporting structure 1 is made, with the exception of the landing and disembarking zone 3 below, in the form of a circular cylinder, however, it may also have a different shape, for example, elliptical. In landing zone 3, the outer surface 4 is straight to create (not shown) a long horizontal landing zone for passengers. Under drive zone 3, drive 5 is located, which in practice is housed in a machine case so that it is not visible from the outside.
On the supporting structure 1, rails 6 are mounted on the outer peripheral surface 4, on which the running rollers 7 roll, which are mounted on the bogies 8 of the cabs 2. The individual cabs 2 are connected and held at a predetermined distance from each other using one or more connecting ropes 9, which by means of clamps 10, they are firmly connected to the carriage 8 of each cab 2. Instead of connecting ropes 9, other connecting means can also be provided. However, the use of three connecting ropes is preferable, since a more stable and reliable connection of the cabins 2 to each other is provided.
Figure 3 shows two more pairs of additional running rollers 11 on each trolley, which serve to support the cabs 2 when they are suspended in the zone 3 of landing and disembarkation under the structure 1.
Platforms are located in cabs 2, if necessary, with seats that are always held horizontally with the help of special devices, while the cab rotates when handling around the supporting structure.
The cabs are driven through a single closed rope 12, which, with two loops 12a and 12b, engages on both sides of the cab 2 through the running rollers 8 and the carriage 8 of the cab 2. The running rollers in this embodiment serve simultaneously as friction rollers, so that due to the synchronous advancement of both cable loops 12a and 12b, the running rollers 7 are affected by friction forces, which provide translational movement of the cab. Due to the selected form of transmission, the efforts of the cab 2 are moved at half the speed of both rope loops 12a and 12b of the traction rope 12.
The rollers 8 in FIG. 4 embodiment, made differently from the embodiment shown in figure 3, namely in the form of twelve running rollers, of which four pairs are rolling on one side of the rails 6, and the other four rollers are rolling on the opposite, inner side of the rails 6. Number running rollers may vary depending on the load.
Figure 4 also shows another type of connection between the rope loops 12a and 12b and the cart 8. In this embodiment, the rope loops 12a and 12b act on individual friction wheels 13, which, although mounted rotatably on the cart 8, can however be locked when normal operation so that they cannot rotate. Due to friction between the rope 12 and the friction wheels 13, the cabs move at the same speed as the rope loops 12a and 12b. A description of the action of the swivel bearings of the friction wheels will be given below.
In the area of the drive 5, as shown in detail in the first embodiment of the invention in FIG. 5, two drive pulleys 14 are provided which are driven by the motors 15. The drives rotate at the same speed in opposite directions of rotation. The synchronous operation of both drive pulleys is achieved by technical control measures or by mechanical coupling of both drives. Above the drive pulleys 14a, 14b, two pairs of guide rollers 16a, 16b and 17a, 17b are provided, which are rotated with respect to each other with their rotation axes. Due to this displaced arrangement of the guide rollers, both cable loops 12a and 12b can be crossed in the area of the drive 5. Namely, as shown in FIG. 5, the left cable of the loop 12a passes through the guide roller 16a and the drive pulley 14a, then passes through the guide roller 17b and leaves the actuator 5 in the cable loop 12b. On the opposite side, the left loop of the loop 12b passes through the guide roller 16b to the drive pulley 14b and exits through the guide roller 17a from the drive 5 into the cable loop 12a. In other words, the rope 12, when passing through the actuator 5, passes from the rope loop 12a to the rope loop 12b and from the rope loop 12b to the rope loop 12a.
Since both rope loops 12a, 12b are formed by one closed rope, absolutely synchronous running of both rope loops 12a and 12b is ensured, so that the cabs 2 are free from skew, which not only minimizes the cost of supporting the carriage 8 on the rails of the supporting structure 1, but also provides minimal wear to the trolley and rail.
After mounting the attraction according to the invention, it is necessary to first run the drive 5. The need for this operation is dictated by the impossibility of manufacturing both drive pulleys 14a and 14b with identical diameters and circles, however, this requirement is necessary, since only a single reversible rope is used and therefore both rope loops 12a, 12b should be driven at the same speed.
By running in, the differences in the geometry of both drive pulleys 14a and 14b are eliminated, which is primarily due to mechanical abrasion on the drive pulleys 14 and / or 14b. However, during break-in, it is preferable that the cabs 2 do not move. For this reason, in the embodiment of FIG. 4, the friction rollers 13 first rotate freely, so that the traction rope 12 can roll along them without moving the cabs 2. Only when the run-in is completed do the friction rollers 13 lock so that the cabs 2 move at the same speed as the rope 12, due to the connection with the frictional closure between the rope 12 and the friction rollers 13.
As shown in the drawings, the rope 12 is adjacent to the outside of the running friction rollers 7 and 13, so that the tensioned rope 12 in addition to the tensioned connecting ropes 9 firmly presses the cabs 8 to the rails 6. However, at the beginning of the landing and disembarkation zone 3, the rope 12 is removed from the running friction rollers 7, 13, since the rope 12 extends directly to the guide rollers 16a, 16b, while the guide web 4 with the rails 6 extends further horizontally. The cabs 2 are driven until a new contact is established between the rope 12 and the friction rollers 7, 13 at the end of the landing and disembarkation zone 3 through the connecting ropes 9, by means of which the carts 9 of the cab 2 are held pressed against the rails 6. In addition, as mentioned above , running rollers 11 are provided (see FIG. 3) located radially inside a pair of 8 running rollers (see FIG. 4), which prevent the hanging nacelles 2 from coming off the rail 6.
Instead of connecting with a frictional closure between the rope 12 and the trolley 8 in the form of friction rollers 13 (see FIG. 4) or travel rollers (see FIG. 3), it is fundamentally possible to also choose other types of connection between the rope 12 and the trolleys 8. For example detachable connecting clamps on the trolleys are provided, by means of which the cabs 2 are disconnected from the rope at the beginning of the landing and landing zone 3, and again connected at the end of the landing and landing zone 3.
Figures 7 and 8 show an alternative embodiment of the drive 5. Again, two drive pulleys 18a and 18b are provided, which in this embodiment rotate, however, in the same direction and are rigidly connected to each other through the shaft 21. Both drive pulleys 18a and 18b driven by one or two engines 22, and the use of two engines 22 is preferable, since the operation of the attraction can be continued in this case even if one engine fails, albeit with less power, due to the disconnection of th of the drive motor of the shaft 21.
In the embodiment shown in FIGS. 7 and 8, there are two coaxially located guide rollers 20a and 20b on the output side, and two guide rollers 19a and 19b, which are located next to each other, but with inclined axes of rotation, are provided on the input side. In addition, on the input side, in front of both guide rollers 19a and 19b, there is a guide device 23, which has two pulleys 24a and 24b mounted coaxially and rotating opposite to each other. In this case, the crossing of both rope loops 12a and 12b takes place in the area between the guide device 23 and both guide rollers 19a and 19b. Namely, the cable rope loop 12a, coming, as shown in Figs. 7 and 8, from the left passes through the upper pulley 24a of the guide device 23 to the guide roller 19b and through the drive pulley 18b, then passes through the guide roller 20b and leaves the drive 5 in the cable loop 12b. On the other side, the cable coming from the left of the cable loop 12b passes through the lower pulley 24b of the guide device 23 under the cable of the cable loop 12a and exits through the guide roller 19a, the drive pulley 18a and the guide roller 20a from the drive unit 5 to the cable loop 12a.
Although in the embodiment according to FIGS. 7 and 8, as compared to the embodiment according to FIGS. 5 and 6, an additional guide device 23 is required, it has the indicated advantages with respect to the synchronous drive of both drive pulleys 18a and 18b due to mechanical coupling through the shaft 21.
