The invention provides a radioactive material vertical sealing transportation structure, and belongs to the technical field of nuclear. When radioactive materials are transported to the vertical channel in the sealed channel, the fork unit forks the radioactive materials from the first horizontal channel or the second horizontal channel, and after the radioactive materials are forked, the control unit controls the first driver and the second driver to move upwards or downwards at the same time. Due to the fact that a traveling wave magnetic field exists between the first driver and the first secondary plate, the pallet fork unit is driven by the traveling wave magnetic field to move along with the first driver. And a traveling wave magnetic field also exists between the second driver and the second secondary plate to drive the locking piece to be away from the vertical rod. When power is suddenly cut off, the magnetic field between the second driver and the second secondary plate disappears, the locking piece drives the locking piece to get close to the vertical rod under the action of the elastic force of the spring, and therefore the braking effect on the pallet fork unit is achieved, and the situation that the pallet fork unit is out of control in the falling process, and radioactive material leakage is caused is avoided.

    本发明提供了一种放射性物料垂直密封运输结构,属于核技术领域。当放射性物料在密封通道内运输到垂直通道时,货叉单元将放射性物料从第一水平通道或第二水平通道内叉取,叉取放射性物料后,控制单元控制第一驱动器和第二驱动器同时向上或向下运动,由于第一驱动器与第一次级板之间存在行波磁场,因此货叉单元在行波磁场的带动下跟随第一驱动器运动;第二驱动器与第二次级板之间也存在行波磁场,带动锁止件远离垂直杆。当突然断电时,第二驱动器与第二次级板之间的磁场消失,锁止件在弹簧自身弹力的作用下带动锁止件靠近垂直杆,从而对货叉单元起到止刹作用,避免货叉单元掉落过程中失控,造成放射性物料泄露。
