Platform type container special for steel coil transportation

The invention relates to a platform type container special for steel coil transportation, and aims to solve the problems that an existing steel coil transportation container is limited by the space of a general container in marine transportation, and the occupied space is large when the container is stacked during recycling; in railway transportation, grass mats and steel wire ropes are made of disposable materials and can only be discarded after being used, the grass mats need to be subjected to special flame-proof treatment, the environment is polluted, and the cost is high; and if the steel coils are not firmly loaded and reinforced during automobile transportation, huge potential safety hazards exist. The container comprises a platform type frame structure, three clamping grooves formed in the frame structure in the longitudinal direction and used for loading and transporting steel coils, and three transverse stopping devices arranged in the three clamping grooves correspondingly. The clamping groove is u
