The utility model has the advantages that:
(1) low labor intensity
The roller is installed additional to the platform for artifical at the removal fuel rod in-process, can send the fuel rod to appointed station more easily, and need not drag of longer distance, in addition, owing to there is the regulation extension board, as long as a fuel rod can smoothly pack into the dress box in advance, and a plurality of fuel rods on the same floor all can directly be packed into, have saved artifical a time of aliging.
(2) High personnel utilization rate
The original supporting platform needs at least 5 persons to operate, wherein 2 persons stand at two sides of the supporting platform respectively and act as baffles to prevent the fuel rods from accidentally falling off.
(3) The fuel rod has high safety
Due to the fact that the baffle is added, manual protection is not needed, reliability and safety are improved, and the risk that the fuel rod accidentally falls to the ground is reduced to 0.
(4) The quality is ensured
Because the manual labor intensity and the difficulty are reduced, the manual operation of the fuel rod is more standard and safer in the filling process, and because some structures, such as rollers and the like, reduce the friction force, the risk of scratching or scratching the surface of the fuel rod is also reduced.
