Description

The invention relates to the entertainment industry.

Currently, there are a large number of Ferris wheels in which, in order to increase the efficiency of the distance between the axis of rotation of adjacent passenger seats, less than the distance equal to twice the height of the passenger seat (the distance from the bottom point of the passenger seat to the axis of rotation), which can lead to a collision of passenger seats with strong gusts of wind (see RF patent No. 2174855 from 10.20.2001).

The technical result to which the invention is directed is to exclude the possibility of collision of cabs, and, in addition, the invention allows damping of vibrations of passenger seats (cabs), which will improve passenger comfort on any type of Ferris wheel.

This result is achieved by the fact that the Ferris wheel is equipped with devices that resist the rotation of passenger seats and have elements kinematically connected with the passenger seats or with the axis of rotation, which can be made in the form of damping devices, friction magnets, etc.

The magnetic damping device comprises a reactive brake element kinematically connected with the passenger seat or its pivot axis and permanent magnets fixed to the supporting elements with the possibility of relative movement. The reactive brake element may be in the form of a disc, and permanent magnets are located on both sides of the disc. The kinematic connection can be made frictional or gear and, for example, may contain a leading element connected to the passenger seat or its axis, interacting directly or through an intermediate connection with the driven reactive brake element.

The invention is illustrated in the drawing.

The Ferris wheel contains cabs 1 (passenger seats), mounted for rotation on the supporting elements 2 by means of suspensions 3. On the axis 4 of the cab 1, at least on one side of the cabs, a driving element 5 is fixed. Directly or via an intermediate connection (shown by a dotted line) the leading element is connected with a reactive brake disc 6. On both sides of the disc are permanent magnets 7, mounted on the supporting elements 2 or metal structures 8 of the wheel.

A feature of the work of the Ferris wheel is the damping of the vibrations of cabs 1 and / or the limitation of their swaying from gusts of wind and in the case of inappropriate behavior of passengers.

To ensure the normal operation of the Ferris wheel, the parameters of the damping device are selected based on the following provisions:

- the moment arising from the gravity of the cabin must be greater than the braking force arising from the movement of the disk 6 relative to the magnets 7;

- the moment from the effect of the wind load and / or the actions of passengers should not lead to the rotation of adjacent cabs at angles at which their collision is possible, or at angles leading to passenger discomfort.

The use of damping devices (devices that resist the rotation of the cabs relative to the axes of their suspension) can lead to some deviation of the cabs from the vertical, to avoid this phenomenon (reduce the angle of deviation), counterweights are used. Using the transmission mechanism (kinematic connection) of the driving element 5 and the reactive element 6 allows you to set the necessary frequency (speed) of rotation of the element 6, which determines the effectiveness of magnetic damping.
