Hoisting and transferring device for radioactive material cup in box

The invention relates to an indoor lifting and transferring device for radioactive material cups, and belongs to the technical field of radioactive contamination material treatment. The device comprises a truss erected along the side wall of a box chamber and stretching across the box chamber, a longitudinal guide rail sliding block moving pair arranged on the upper surface of the truss, a material cup grabbing mechanism and a cup holder grabbing mechanism. The material cup grabbing mechanism and the cup holder grabbing mechanism are arranged on the same truss and share the same longitudinal guide rail sliding block moving pair, so that the whole hoisting and transferring device is compact and occupies a small space of a box chamber; a material cup longitudinal driving machine, a material cup transverse driving machine, a cup holder longitudinal driving machine and a cup holder transverse driving machine are specially designed, so that a material cup grabbing mechanism and a cup holder grabbing mechanism can
