[0002] Nuclear power production produces waste, which needs to be handled safely to prevent harm to the environment and human health. Nuclear waste treatment is an important part of the nuclear power industry chain and an important issue that must be solved to achieve sustainable development of nuclear energy. Internationally, for the back-end treatment of nuclear fuel, the pressure reducing barrel is also called the pipeline pressure reducing barrel. It is a barrel-shaped container used to reduce pressure in the pipeline system.

[0022] The nuclear power waste is placed in the pressure reducing barrel body 4, and the top plate 1 is conveniently moved by the multiple bottom wheels 3 provided. When the top plate 1 moves to the top of the pressure reducing barrel body 4, the lifting device 6 is started to make the lifting plate 7 descend. As the lifting plate 7 descends, the inclined surface of the clamping block 10 can contact the outer wall of the conical block 5. At this time, the clamping block 10 will compress the spring 11, and the clamping rod 9 will move on the positioning plate 8. When the clamping block 10 moves to the bottom of the conical block 5, the spring 11 is reset, and then the clamping block 10 can be reset. After the clamping block 10 is reset, it will be located at the lower end of the conical block 5. At this time, the lifting device 6 is started again, so that the lifting plate 7 drives the positioning plate 8 and the clamping block 10 to rise. At this time, the clamping block 10 can provide an upward force to the conical block 5, so that the pressure reducing barrel body 4 can be separated from the ground, which is convenient for automatically grabbing the pressure reducing barrel body 4, and the operation can save manpower, and the grabbing stability is high, and it is not easy to make the pressure reducing barrel body 4 fall, and the safety factor is high.

[0023] Furthermore, the bottom wheel 3 can be a universal wheel.

At this time, the pull rope 14 can provide a pressure to the clamping rod 9, so that the clamping block 10 can compress the spring 11. At this time, the clamping block 10 will move, so that the clamping block 10 will not touch the conical block 5 when rising.

[0027] The pull rope 14 lacks a guiding structure when being pulled, which will affect the smoothness of the pull rope 14 when being pulled. A plurality of guide shafts 16 for guiding the pull rope 14 are provided on the peripheral side of the lifting plate 7. The guide shafts 16 can provide a guiding structure for the pull rope 14 when being pulled, thereby improving the smoothness of the pull rope 14 when being pulled.
