EXTRAORDINARY SPORT OR CONCERT LARGE-SIZED PLATFORM Russian patent published in 2018 - IPC E04H3/28 A63C19/00 

FIELD: construction.

SUBSTANCE: sliding sports or concert large-scale platform belongs to the field of magnetic-levitation devices, namely to the design of the sliding field of a stadium or a scene with large dimensions and mass based on magnetic levitation and linear thrust. The flat frame 1 in the static mode is in the levitation state due to the magnetic forces of traction (repulsion) of the same-pole elementary permanent magnets of the heteropolar magnetic moving pole 3 and the heteropolar magnetic stationary pole 5. In this case, the gap between the movable and stationary magnetic poles 3 and 5 can reach 100 mm. After the power is applied to the stator 6 of the traction linear motor, the flat frame 1 with the coating 2 in the levitation state moves to the nominal position. To avoid vibrations in the nominal position, the retractable field is fixed by means of the end electromagnetic stoppers 8.

EFFECT: reducing the complexity of installation, increasing operational reliability.
