DEVICE FOR EXTRACTING FALLEN OBJECTS OF NUCLEAR REACTOR Russian patent published in 2019 - IPC G21C19/10 

FIELD: atomic engineering.

SUBSTANCE: invention relates to atomic engineering. Device for extracting fallen objects of a nuclear reactor contains a movable platform with a lifting device, an actuator, a vertical hollow rod and a gripping means comprising gripping legs on the lower ends of two pivot levers that are articulated by protrusions made in the middle part of the levers. Levers are pivotally connected in the upper part with two links. Device contains a support frame where the drive is placed, equipped with cables, rods, and the traverse with two gripping means placed at ends thereof, connected to the cables, rods of the drive. Support frame in the upper part is connected with a lifting device, and in the lower part with a fixed section of a hollow rod, made telescopic. Movable section of the rod is connected with the cable-pitch of vertical movement thereof and in the lower part is connected pivotally with the middle part of the traverse. Each gripping device includes a hollow body with a slot, in the lower part of which an axis of the hinged connection of the protrusions of the two levers is located, and a movable load connected to the cable-traction located inside the body.

EFFECT: invention allows to increase the operational reliability, to ensure the possibility of adjusting the position of the gripping device, excluding damage to the object at the time of engagement.
