Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical structures, and particularly relates to a steel frame box for thermally bent and insulated pipes in marine transportation. Background Art

[0002] A transport box is an efficient logistics transport tool with high loading and unloading efficiency. Since the transport ship stays in the port for a short time, the utilization rate of the transport box is improved. The transport box can simplify the packaging of goods, save costs while protecting the safety of goods, and has the advantages of being convenient for stacking, hoisting, and fastening, etc. Therefore, it is widely used in the transportation field.

[0003] Existing conventional transport boxes, such as conventional wooden boxes, have insufficiently firm packaging. It is often necessary to specially design and customize corresponding transport frame structures for the goods. After the transportation task is completed, due to the particularity and pertinence of their sizes, these frame structures are often not suitable for the transportation of other goods and are directly discarded, with low material utilization rate, resulting in high transportation costs. Ordinary containers are large and bulky, with fixed length, width, and height dimensions, often causing space waste and being difficult to meet the shipping requirements.

[0004] When thermally bent and insulated pipes are transported by sea, they need to be placed in multiple layers with stable separation to avoid friction damage between them. At the same time, it is necessary to ensure appropriate dimensions to meet the needs of marine transportation and improve the utilization rate of the box body. Lifting lugs are designed at appropriate positions on the outer part of the box body to facilitate lifting and stacking and ensure transportation efficiency. At present, there is a lack of the above-mentioned frame box specifically suitable for the transportation of thermally bent and insulated pipes on the market. Summary of the Utility Model
