Definitions

  • the invention relates to a circular ride with booms rotatable and drivable about a central axis, on which passenger carriers are arranged, and with a lifting device which has a central lifting member which can be moved and driven essentially in the direction of the central axis and which has a boom with all the booms Passenger carriers are pivoted in the same direction about pivot axes which are tangential to the central axis and thus raise and lower at the same time.
  • Such a tour business is described for example in FR-A-2142726 or in DE-GM-18 98 369.
  • the central lifting member can be accelerated at least in sections during the downward movement of the booms in such a way that the acceleration of the passenger carriers at least reaches the acceleration due to gravity.
  • the lifting member can be moved up and down in the same direction as the booms with the passenger carriers arranged thereon (this does not mean the exact movement path, but only the direction of movement in the upward or downward direction); accordingly, the lifting element moves in the same direction as the boom is pivoted.
  • a device is provided for dropping the lifting member in the downward direction, at least in sections without a drive, whereby the acceleration of the passenger carriers can be brought to at least gravitational acceleration in a structurally particularly simple manner.
  • a rechargeable energy store which acts on the lifting element in the upward direction, as a result of which the passenger carriers are accelerated particularly strongly during their upward movement, which gives the feeling of a 'launch'.
  • a device is provided for this purpose - in particular sudden - relaxation of the energy store when the lifting element is essentially in its lower end position; depending on the desired lifting process, this device can not only relax suddenly, but also in a controlled manner.
  • a device for charging the energy store should be provided during the downward movement of the lifting member so that the energy store is ready for use again when the lifting member has reached its lower end position.
  • the lifting element can preferably be moved and driven along the central axis.
  • the linkage is also essentially only subjected to tension.
  • the linkage comprises rods which are articulated at one end to the arms.
  • the rods should advantageously be articulated on the cantilevers between their pivot axes and the attachment points of the passenger carrier, as a result of which the Movement path of the passenger carrier is longer than that of the central lifting element and thus the passenger carriers have a higher lifting and lowering speed than the lifting element. Since the lifting device only requires a shorter movement path in this embodiment, the overall height of the circular ride and thus also its construction volume can be kept low, which is not only advantageous for structural and structural reasons, but also enables easier transport, but without the movement path of the passenger seats from their lower position to their upper position and thus to influence or even reduce the special driving sensation caused thereby.
  • the point of articulation of the rods on the arms is preferably between their pivot axes and the passenger carriers.
  • the rods are expediently coupled with their other ends to the central lifting element, for which purpose a rotating element is preferably rotatably mounted on the lifting element, to which the rods are articulated with their other ends.
  • the rotating element For space and design considerations, it is advantageous to arrange the rotating element on the lifting element above the pivot axes of the boom. So that the rods are arranged essentially in the direction of the tensile forces for efficient power transmission, the rotating element should have sections projecting essentially radially from the central axis, to which the rods are articulated with their other ends. These radial sections can now be dimensioned such that the rods are oriented essentially in the direction of the tensile forces that occur.
  • the centrifugal forces acting in the rods are reduced compared to the forces required at standstill to lift or hold the boom arms due to the influence of the centrifugal forces, since the centrifugal forces strive to move the booms into one Raise the position essentially perpendicular to the central axis.
  • the centrifugal forces exert an opposite effect since they try to pull the booms down so that the tensile forces are correspondingly higher.
  • the centrifugal force can be used particularly advantageously for the downward movement of the passenger carriers from the upper end position into the lower end position.
  • the booms with the passenger carriers arranged thereon can experience such an acceleration that a 'free fall' equals so that the passengers are given the feeling of free fall.
  • the centrifugal forces begin to act as a brake, which is also desirable in order to bring the passenger carriers safely into their lower end position.
  • the previously described use of the centrifugal force represents an independent aspect of the present invention.
  • the articulation points of the rods on the rotating element and on the brackets should each have the same radial distance from the central axis.
  • the central lifting element is partially arranged within the central structure, which results in a particularly space-saving construction.
  • a braking device should also be provided for storage of the braking energy during the downward movement of the boom, not least for safety reasons.
  • the braking device can be activated intermittently during the downward movement of the booms in order to achieve luffing effects, which further increases the attraction of this circular ride.
  • the lifting device expediently has a lifting cylinder, the piston rod of which forms the lifting element, the lifting cylinder preferably being a hydraulic lifting cylinder which is connected to a hydraulic circuit.
  • the energy store is a hydraulic accumulator and the device for essentially suddenly releasing the energy accumulator has a proportional valve connected between the hydraulic accumulator and the lifting cylinder, which is opened essentially suddenly when the lifting element is essentially in its lower end position, and in particular accordingly a predetermined control curve is closed again until the lifting member reaches its upper end position.
  • a hydraulic pump provided as a charging device expediently recharges the hydraulic accumulator, as a result of which the lifting operation of the piston rod is carried out Lifting device for the next upward movement of the passenger carrier can be initiated essentially immediately.
  • the aforementioned braking device as a hydraulic shock absorber that can be connected to the hydraulic circuit.
  • the device for dropping the lifting element has a proportional valve connected between the lifting cylinder and the rest of the hydraulic circuit, which valve opens essentially suddenly when the lifting element is essentially in its upper end position, and in particular is gradually closed again during a predetermined control curve until the lifting member reaches its lower end position.
  • a proportional valve has the advantage that, on the one hand, an abrupt opening and, on the other hand, a controlled closing can be realized, so that the closing can take place after a controlled curve, for example a ramp function, as a result of which the lifting member and thus the passenger carrier are braked gently is possible when the lower end position is reached.
  • the passenger carriers can also be pivoted on the brackets about a horizontal axis and / or rotatably and driveably about a vertical axis. If pendulum movements around the horizontal axis are not desired, a mechanism can also be provided which holds the passenger carrier in the horizontal position in each swivel position of the boom, so that the vertical axis is always aligned vertically or parallel to the central axis.
  • FIG. 1 schematically shows a circular ride, on the base frame 2 of which is designed to be movable for transport purposes, a fixed column-like central structure 4 is arranged vertically, the central axis of which simultaneously forms the central axis 6 of the circular ride.
  • a rotating body 8 is rotatably mounted about the central axis 6, on which a plurality of extension arms 12 are articulated via horizontal pivot axes 10 which are tangential to the central axis 6.
  • Plate-shaped passenger carriers 16 are suspended from the free ends 12a of the extension arms 12 about a horizontal pivot axis 14 which is tangential to the central axis 6.
  • the passenger carriers 16 are still rotatable about a vertical axis of rotation 18 parallel to the central axis 6 and can be driven by a motor (not shown in more detail), the seats (not shown in the figures) being arranged in a partially circular manner around the vertical axis 18 with a constant radial distance, as shown in Figure 2.
  • the free ends 12a of the extension arms 12 are fork-shaped and the passenger carriers are suspended between the fork ends so as to be pivotable about the horizontal axis 14.
  • the rotating body 8 is driven by a motor, not shown, which is preferably an electric motor, as a result of which the cantilever arms 12 are set in rotation about the central axis 6 with the passenger carriers 16.
  • a motor not shown, which is preferably an electric motor, as a result of which the cantilever arms 12 are set in rotation about the central axis 6 with the passenger carriers 16.
  • a fixed hydraulic lifting cylinder 20 is arranged within the vertical, fixed, columnar central structure 4, the central axis of which coincides with the central axis 6. From the upper end 20a of the lifting cylinder 20, which extends beyond the rotating body, an associated piston rod 22 can be extended, on the upper end 22a of which a rotating frame 24 extending transversely to the central axis 6 is rotatably mounted.
  • the rotating frame 24 is provided with radial sections 24a, on which 26 pull rods 28 are articulated at one end via horizontal articulated axes tangential to the central axis.
  • Each tie rod 28 is articulated at its other end to a cantilever arm 12 via a horizontal hinge axis 30 tangential to the central axis 6.
  • the construction described above is rotationally symmetrical to the central axis 6.
  • the pivot axes 10 of the cantilever arms 12, the pendulum axes 14 of the passenger carriers 16, the articulated axes 26 of the tie rods 28 on the radial sections 24a of the rotating frame 24 and the articulated axes 30 of the tie rods 28 on the cantilever arms 12 each have the same radial distance from the central axis 6 and thus the boom arms 12 and the tie rods 28 each have the same length.
  • Such a rotationally symmetrical structure is advantageous in order to avoid unbalance during driving.
  • the circular ride according to the invention is not limited to such a rotationally symmetrical structure, but other arrangements are also conceivable in principle.
  • the central axis 6 does not necessarily have to run vertically, as shown in FIG. 1, but can also basically run at an angle to the vertical of the earth, so that the entire circular ride can also be arranged at an angle.
  • the piston rod 22 extends from the lifting cylinder 20, it takes the booms 12 with it via the pull rods 28, whereby the booms 12 are pivoted upwards about their pivot axes 10 (which are fixed in the vertical direction). In the lower end position, which is labeled "I" in FIG.
  • the extension arms 12 point obliquely downward, and the passenger carriers 16 are located approximately at the height of the base frame 2, so that they are easily accessible for getting in and out.
  • the extension arms 12 point obliquely above. Due to the construction described above, the passenger carrier 16 has a higher lifting and lowering speed than the piston rod 22. In the exemplary embodiment shown, the stroke of the passenger carrier 16 is approximately twice that of the piston rod 22.
  • the piston rod 22 is driven by a hydraulic circuit 40, the most important components of which are shown schematically in the block diagram in FIG.
  • the lifting cylinder 20 receiving the piston rod 22 is via a proportional valve 46 connectable to the remaining hydraulic circuit 40.
  • a hydraulic gas shock absorber 44 can be activated via a first 2-way valve 42.
  • a hydraulic accumulator 48 can be activated via a second 2-way valve 47.
  • the hydraulic accumulator 48 consists of a piston accumulator 48a and nitrogen bottles 48b.
  • the piston accumulator 48a has a liquid compartment which communicates with the rest of the hydraulic circuit 40 and a gas compartment which is separated from the liquid compartment via a piston and connected to the nitrogen bottles 48b.
  • a third 2-way valve 49 is connected in parallel to the second 2-way valve 47, which empties the hydraulic oil into a tank (not shown).
  • a hydraulic pump 50 is connected via a check valve 52 to the hydraulic line between the second 2-way valve 47 and the hydraulic accumulator 48.
  • the piston rod 22 can also be raised slowly by slowly or controlled opening of the proportional valve 46, if the feeling of the 'launch-like' upward movement is not desired.
  • the proportional valve is slowly closed again, specifically according to a predetermined control curve, which has the shape of a descending ramp, for example, whereby the piston rod 22 is braked accordingly gently until it reaches its upper end position 2.
  • a predetermined control curve which has the shape of a descending ramp, for example, whereby the piston rod 22 is braked accordingly gently until it reaches its upper end position 2.
  • the proportional valve 46 is completely closed again. Then the second 2-way valve 47 is closed again.
  • the hydraulic pressure in the hydraulic circuit 40 can also be generated and influenced directly by the hydraulic pump 50, in such a way that it increases
  • the beginning of the lifting process that is when the boom arms 12 with the passenger carriers 16 are in their lower end position 1, is lower when the circular ride is rotating than at the end of the lifting process, where the boom arms 12 with the passenger carriers 16 are in their upper end position II.
  • This mode of operation takes into account the fact that when the rotating body 8 rotates at the beginning of the lifting process, the centrifugal force assists the lifting of the cantilever arms 12, after exceeding a horizontal plane formed by the pivot axes 10 attempts to prevent the cantilever arms 12 from being raised or pivoted, and so on more, the further the boom arms 12 are raised towards the upper end position II.
  • the tensile forces acting on the cantilever arms 12 from the tie rods 28 when the circular ride is rotating may be smaller than the forces which have to be applied to raise the cantilever arms 12 when the circular ride is at a standstill, and must then be increased continuously so that they then must be correspondingly higher in the upper end position II in order to compensate for the restoring effect of the centrifugal force.
  • the proportional valve 46 is suddenly opened, as a result of which the piston rod 22 and thus the extension arms 22 with the passenger carriers 16 in Downward direction are first 'dropped without power', which is equivalent to a 'free fall', so that the passengers are given the feeling of free fall.
  • the centrifugal force is used particularly advantageously for the downward movement of the passenger carrier 16 from the upper end position II into the lower end position 1.
  • the cantilever arms 12 with the passenger carriers 16 attached to them can receive the desired high acceleration due to the supportive effect of the centrifugal force at the start of their downward movement from the upper end position II in order to achieve at least gravitational acceleration in order to realize the free fall.
  • the centrifugal force has a braking effect, which is also desirable in order to bring the passenger carriers 16 safely into their lower end position l.
  • the piston rod 22 is also moved into the lifting cylinder via the pull rods 28, so that the hydraulic oil is pressed back out of the lifting cylinder 20 into the hydraulic circuit 40.
  • the hydraulic gas shock absorber 44 can be activated during the braking phase in order to store energy.
  • the hydraulic gas shock absorber 44 is initially only switched on intermittently in order to achieve rocking effects.
  • the proportional valve 46 is gradually closed again, specifically in accordance with a predetermined control curve, such as a descending ramp, so that the piston rod 22 and thus the extension arms 12 with the passenger carriers 16 attached to them are safely returned to their lower end position l reach.
  • the driving impression is further enhanced by the fact that during the downward movement the passenger carriers 16 are set in more or less strong oscillating movements about the horizontal axis 14, which can sometimes also lead to a rollover. It is precisely because of the intermittent braking that the pendulum movements of the passenger carriers 16 can rock up.
  • the hydraulic circuit should expediently be designed and the hydraulic pressure should be controlled so that in the upper end position II the operating pressure is approximately equal to the brake pressure.
  • the time during the downward movement of the boom arms 12 is used to charge the hydraulic accumulator 48 by the hydraulic pump 50. In this way, it is possible for the hydraulic circuit 40 to be prepared more quickly for the next lifting operation, so that the next lifting operation can be started immediately.
  • the stored hydraulic oil from the hydraulic gas shock absorber can also be used for the lifting process.
  • the circular ride described above has four degrees of freedom, which creates particularly 'complicated' and thus interesting cycloidal movements. Specifically, while the extension arms 12 with the passenger carriers 1 6 hanging thereon are rotated in the horizontal direction about the central axis 6, they are simultaneously pivoted upwards and downwards, as a result of which the passenger carriers 16 are also made to oscillate about the horizontal pendulum axis 14. At the same time, the passenger carriers 16 are also rotated about the vertical axis of rotation 18.
