FIELD: mining industry.

SUBSTANCE: invention can be used for movements in three-dimensional space at different angles in mines. The magnetic elevator system in underground mines includes magnetic lines and elevator cages. The cages comprise cabins with magnetic guides consisting of hollow disks, and rotating disks located at the intersection of vertical and horizontal magnetic rails of the mains, and representing a rotating device designed to rotate the elevator cage. The cabin remains vertical. The system further includes a turntable assembly for closing the elevator shaft and a lifting rail assembly. The turntable assembly includes a platform that is rigidly attached to the toothed arches. They are tightly adjacent to the gears for the elevator shaft closing platform, which are removably connected to electric motors, which are connected to a common electrical network and to a system of supercapacitors. The platform's horizontal rails are removably secured to the platform. The movable rail element is fixed to the vertical wall of the elevator shaft. A rail stand is rigidly attached to it, on which gears for the movable rail element are removably attached, connected to a gear control mechanism, which is removably fixed inside the rail stand and connected to the capacitors. Under the moving rail element inside the rail stand there is a socket for recharging the capacitors. The lifting rail assembly consists of a platform for lifting rails and rail elements with cut-outs. The lifting rail platforms are rigidly attached to toothed arches that fit tightly to the lifting rail gears, which are removably connected to the electric motors. The lifting rails are removably secured to the platform for the lifting rails. The rail elements with cutouts are rigidly attached to the platform for the rails with cut-outs, in which mechanisms for rotating the gears for the rail elements with cut-outs are removably fixed, which are connected to capacitors inside the platforms; behind the rail elements with cut-outs there are segments of the magnetic line, which are removably attached to horizontal surface of an underground mine. Perpendicular to its direction, opposite the rail elements with cut-outs, sockets for recharging the capacitors are removably installed inside the platforms for the rails with cut-outs. Magnetic guide platforms are installed on the hollow disks of the elevator cabin, inside which inductance coils are removably installed. Moreover, permanent magnets and a gripper are removably installed on the platforms of the magnetic guides by means of a platform for permanent magnets. Fasteners are rigidly attached to the platform for permanent magnets, into which rods and permanent magnets are removably installed. A movable wedge with an electric pusher is installed inside the platform for permanent magnets.

EFFECT: increased reliability of the device and speed up the process of movement in underground workings.
