Description

TECHNICAL FIELD

[0001] The present application relates to the field of steel processing, in particular to a steel transport vehicle. BACKGROUND

[0002] Hot-dip galvanizing is a widely used steel corrosion protection technology, which is widely used in steel pipes, steel wires, steel bars and other steel products. The process flow of steel during hot-dip galvanizing mainly includes pickling, water washing, immersion of plating solvent, drying and preheating, plating, cooling, passivation, cleaning, polishing, etc.

[0003] Before the steel is pickled, it is transported in bundles. If the bundled steel is directly placed in the pickling tank for pickling, the steel may not be able to spread out, resulting in insufficient pickling of the steel. In order to solve the above problem, the steel needs to be unpacked before pickling. After unpacking, the steel is dispersed on the transport vehicle, and then the transport vehicle is used to transfer the steel to the pickling tank for pickling. The existing transport vehicle is mostly a flatbed transport vehicle. When the unpacked steel is placed on the transport vehicle for transfer, the steel may fall off, which may injure the workers and cause safety accidents. CONTENT OF THE INVENTION
