The invention discloses a movable workbench for cutting whirlcone abrasion resisting bricks, and belongs to the technical field of whirlcone maintaining equipment, and aims at achieving field cuttingof whirlcone lining abrasion resisting bricks. According to the technical scheme of the movable workbench, two guide rails are fixed to one side of a bottom plate in parallel, the lower bottom face ofa movable platform is in rolling connection with the guide rails through wheel shafts, a brick pressing lead screw is arranged on the tabletop of the movable platform, and the lower end of the brickpressing lead screw is connected with a horizontal brick pressing plate opposite to the tabletop of the movable platform; the abrasion resisting bricks are placed on the part, below the brick pressingplate, of the tabletop of the movable platform; two cutting machine fixing columns are vertically and fixedly connected to the parts, on the other sides of the guide rails, of the bottom plate, and ahorizontally-placed cutting machine fixing plate is connected with the two cutting machine fixing columns; and a cutting machine is fixed to the plate face of the cutting machine fixing plate, and acutting blade of the cutting machine is opposite to the abrasion resisting bricks on the movable platform. The movable workbench is simple in structure and convenient to operate, the operation safetyand work efficiency can be effectively improved, the finished product quality is stable, and a reliable guarantee is provided for whirlcone abrasion resisting lining maintenance.
