た。 The auxiliary building (fuel handling building) inside the nuclear power plant handles nuclear fuel, so it is almost impossible to open the building for work (it is only opened when loading and unloading items). Under these circumstances, the self-propelled trolley of the overhead crane installed near the ceiling of the building in question was replaced due to changes in the standards for casks used when transporting spent nuclear fuel. When it is necessary to increase the lifting capacity from 100 tons to 120 tons, the strength of the ceiling beams must be weak and impossible. Furthermore, the space between the ceiling of the building and the overhead crane is narrow, and it is not possible to bring in a truck crane or gin pole to lift the old self-propelled trolley or the new self-propelled trolley. Additionally, bringing in a truck crane, etc. made the narrow building even more cramped, which caused problems with the work.

ができる効果がある。 The lifting and unloading device for a self-propelled trolley according to the present invention is constructed as described above, and can achieve the following effects. That is,
As already mentioned, due to changes in the standards for casks used for transporting spent nuclear fuel,
When it was necessary to increase the lifting capacity from 100 tons to 120 tons by replacing the self-propelled trolley of the overhead crane installed near the ceiling of the building, the ceiling beam of the building was replaced with the old self-propelled trolley. The ceiling beams are too weak to be used for hanging or lifting the new self-propelled trolley. Furthermore, the space between the ceiling of the building and the overhead crane is narrow, and it is not possible to bring in a truck crane or gin pole to lift the old self-propelled trolley or the new self-propelled trolley. In addition, when a truck crane or the like is brought in, the narrow building becomes even narrower, which hinders the work.However, in this invention, as mentioned above, the crane is installed on the floor and the crane is brought in from the same floor. A frame structure having a substantially rectangular frame shape extending upward from the side position of the girder, a suspension frame provided on the frame structure so as to be able to rise and fall, and a lifting drive device for the suspension frame provided on the frame structure. , a horizontal pulling rail provided on the suspension frame, and a horizontal pulling rail on the suspension frame installed on the crane girder so as to intersect with the self-propelled truck traversing rail. A connecting rail for horizontal pulling that connects to the mobile rail, a plurality of jacking devices for pushing up the self-propelled bogie provided on the crane girder, and a wheel block for the connecting rail that is detachably attached to the self-propelled bogie. Since the old self-propelled cart is suspended and the new self-propelled cart is lifted, the self-propelled cart can be lifted and unloaded without any trouble even in buildings with very narrow radiation pipe areas.
