Steel-plate descaling device

A steel-plate descaling device, comprising a plurality of steel-plate surface descalers and a plurality of steel-plate side-surface descalers disposed along a device moving direction and a trolley rail disposed in parallel to one side of the device,

• wherein the steel-plate surface descaler and the steel-plate side-surface descalers all comprise a descaling roller for polishing a steel plate through rotation, and at least one roller-changing vehicle is disposed on the trolley rail to be slid back and forth, and
• the roller-changing vehicle is disposed with a roller-changing mechanism, and when the roller-changing vehicle travels to a front side of the steel-plate surface descaler, the roller-changing mechanism extends into the steel-plate surface descaler to perform a roller-changing operation,
• wherein the roller-changing vehicle comprises a base, the base is connected with a first transmission mechanism which drives the base to travel, two roller-guiding seats are disposed side by side on the base, the roller-guiding seat is connected with a roller-guiding-seat driving mechanism, the roller-guiding seat moves along a longitudinal direction of the roller-guiding seat through an acting of the roller-guiding-seat driving mechanism, a moving direction of the roller-guiding seat is perpendicular to a moving direction of the base, the roller-changing mechanism for supporting the descaling roller is disposed correspondingly on each of the roller-guiding seats, and the roller-changing mechanism moves forward or backward through an acting of a second transmission mechanism along a longitudinal direction of the roller-guiding seat.
