Background
According to the requirements of the radioactive article safety transportation regulations, the radioactive article transportation container needs to be capable of withstanding various tests under normal transportation conditions and transportation accident conditions, and especially after the free-falling test I and the free-falling test II are carried out, the container needs to ensure structural integrity.
The standard requires that the sample should fall freely on a bar that stands firmly on the target in order to be most severely damaged when free fall test ii is performed. The height from the intended point of impact of the sample to the end face of the rod should be 1m. The rod should be made of round solid mild steel with a diameter of (15.0.+ -. 0.5) cm and a length of 20cm, and if a longer rod would cause more serious damage, a sufficiently long rod should be used. The tip of the rod should be flat and horizontal with rounded edges and a radius of no more than 6mm.
However, for large tonnage and large size containers, when the free fall test II is performed, the bar is easily deformed due to the overlarge falling attitude angle, so that the free fall test II cannot be realized.

In order to achieve the above purpose, the utility model adopts the technical scheme that:
the utility model provides a large-scale B type cargo package test verifies with penetrating stake, is including penetrating the stick run-through bottom of the stick sets up the base, will run through the stick and set up to the big coaxial stick of running through of upper portion pipe diameter little lower part pipe diameter.
Further, a plurality of reinforcing ribs are uniformly distributed along the circumferential direction of the penetrating rod.
Further, the reinforcing ribs are arranged on the large-diameter part of the lower part of the penetrating rod.
Further, four lifting lugs are designed at four corners of the base.
Further, the penetrating pile is made of carbon steel.
Further, the carbon steel is Q345 steel.
Further, the diameter of the small pipe diameter part at the upper part of the penetrating rod is 150mm, and the diameter of the large pipe diameter part at the lower part is 300mm.
Further, the height of the small pipe diameter part is 325mm, and the height of the large pipe diameter part is 675mm.
Further, the height of the reinforcing ribs is 400mm.
Further, the base is 800 x 800mm 2 Square shape.
The utility model has the following effects: the utility model provides a penetrating pile for testing and verifying a large-sized B-shaped cargo bag, which can be used for testing and verifying the free falling II of a spent fuel transport container, solves the problem that the free falling II is difficult to realize due to overlarge volume of the spent fuel transport container and overlarge falling attitude angle, and has the advantages of high strength, strong shock resistance, strong buffering capacity, high deformation resistance and convenient movement.
