GUIDE DEVICE FOR EXTRACTION OF LATERAL REFLECTORS Russian patent published in 2016 - IPC B66C1/66 

FIELD: nuclear technology.

SUBSTANCE: invention relates to nuclear engineering and can be used for extraction of lateral reflectors of nuclear reactor with liquid metal coolant. Guide device comprises a base, a swivelling plate with a drive, a telescope and a mechanism for moving telescope. Telescope is configured to pass between cases of control and protection system and wall of MBR, docking with head of side reflector is mounted on truck movement mechanism of telescope, connected with rotary plate. Mechanism for moving telescope is made in form of trolley moving along rolling guides located on rotary plate. Drive mechanism for moving telescope is made in form of screw mechanism, a screw which is fixed on rotary plate with possibility of rotation, and a nut, with possibility of linear movement along screw is fixed on carriage movement mechanism of telescope, and provides movement of carriages with telescope fixed on it relative to rotary plate. Drive guide tube of telescope is made in form of screw mechanism, a screw which is installed eccentrically relative to body of telescope with possibility of rotation, and nut with possibility of linear movement along screw and self-alignment relative to guide tube of telescope and provides possibility of movement with force exceeding permitted for container winch rope, at least to height of reactor core.

EFFECT: broader technological capabilities of guiding device, higher reliability of equipment.
