The steel plate transportation system provided by the embodiment is mainly used for a hot rolled plate continuous heat treatment production line, and corresponding heat treatment equipment, such as a heat treatment furnace, such as an annealing furnace/tempering furnace and the like, is arranged at the heat treatment station. When a plurality of heat treatment stations are arranged, the heat treatment stations are sequentially arranged along the guide direction of the transverse moving track 1, wherein the heat treatment stations can be arranged with the same heat treatment equipment or different heat treatment equipment and are determined according to the specific production line design and the like; the steel plates can be subjected to multi-stage heat treatment in each heat treatment station in sequence, or alternatively can enter one of the heat treatment stations for treatment, for example, when two tempering furnaces are arranged, the two tempering furnaces can be standby for each other, or two stacks of steel plates 6 can be treated simultaneously.
In one embodiment, the traverse rail 1 is engaged with a stacker; in another embodiment, the stacker may be equipped with a corresponding steel plate output system, and the steel plate carrier 2 may be used to perform continuous heat treatment of the hot rolled plate. The heat treatment stations are preferably arranged on the same side of the traversing rail 1, although alternatively on different sides of the traversing rail 1.
It can be understood that the side-shifting lower roller 3 can not only input the steel plate stack 6 into the heat treatment station, but also can withdraw the steel plate stack 6 output from the heat treatment station to the steel plate transportation vehicle 2, so that the conveying rollers of the side-shifting lower roller 3 can rotate forward and backward, that is, the driving motor is a forward and backward rotating motor. The conveying direction of the side-shifting lower roller bed 3 is perpendicular to the guiding direction of the transverse moving track 1, that is, the axial direction of the conveying roller of the side-shifting lower roller bed 3 is parallel to the guiding direction of the transverse moving track 1.
