Gripping means for refuelling a nuclear reactor

摘要

The proposed gripping means of a refuelling machine for a nuclear reactor is arranged in a manipulator tube of the machine. Longitudinally extending grooves are provided on the internal surface of the manipulator tube. The gripping means comprises a housing which accommodates a slider with thrust pins which are in contact with the longitudinally extending grooves of the manipulator tube. A working member is secured at one end of the slider. At the opposite end of the slider there is provided a hole to receive a spherical lug provided on a rod. The latter is mounted on the housing of the gripping means and is driven by the machine's drive. The spherical lug of the rod is in contact with the surface of the slider, thus forming an articulated joint, whereby the slider is mechanically coupled to the rod.
