Description

Technical Field

[0001] The invention belongs to the technical field of containers, and in particular relates to a shock absorbing device for a component transport container for a container. Background Art

[0002] Component transport containers are sealed devices used to store and transport radioactive fuel assemblies or other special industrial assemblies. Their main function is to ensure the physical protection, radiation shielding and critical safety of radioactive materials during transportation. Since radioactive fuel assemblies have high requirements for the stability of the transportation environment, the existing transportation methods mainly include land transportation and sea transportation. Land transportation usually uses special cars or train carriages, while sea transportation relies on special cargo ships. However, during transportation, the transport container may be affected by unexpected situations such as vibration, bumps, collisions, tipping over and even falling into the water, which in turn affects the safety of the internal components.

[0003] At present, metal brackets, rubber pads, spring suspensions or hydraulic shock absorbers are usually used to provide a certain degree of shock absorption during the transportation of component transport containers. However, these traditional shock absorption methods have the following problems: 1. Complex fixing methods: Some transport brackets are fixed with rigid structures, which are difficult to be compatible with transport containers of different sizes, resulting in insufficient adaptability and cumbersome loading and unloading processes.

[0004] 2. Limited cushioning effect: Traditional rubber pads or spring suspension structures are prone to aging or fatigue after long-term use, making it difficult to provide long-term and stable cushioning performance, and it is difficult to effectively cushion impact forces in different directions during transportation.

[0005] 3. Insufficient transportation stability: During sea transportation, the transport container may shake significantly due to the action of waves. The existing shock-absorbing structure is difficult to provide all-round support, resulting in a large displacement or impact risk of the container during transportation.

[0006] 4. Inconvenient operation and maintenance: Some existing transport brackets require manual adjustment or disassembly, which not only affects transportation efficiency but also increases maintenance costs. Summary of the invention

[0007] The present invention aims at solving the above problems and provides a shock absorbing device for a component transport container for a container, which has a simple structure, good buffering performance and a reliable fixing method.
