Reinforced supporting device for roadway

The invention discloses a reinforced supporting device for a roadway, and belongs to the field of roadway supporting. The reinforced supporting device comprises the roadway and a base, wherein the base is located in the roadway; a reversed loader is installed in the middle of the upper surface of the base; through holes are symmetrically formed in the base; base fixing equipment is movably arranged in the through holes; sleeves are symmetrically welded to the upper surface of the base; hydraulic cylinders are symmetrically installed on the side walls, away from each other, of the two sleeves;the same vertically-arranged supporting side plate is fixed to one of the ends of piston rods of the two hydraulic cylinders; screws are rotationally installed in the sleeves; first bevel gears are installed on the screws; and first motors are installed on one side walls of the sleeves. The reinforced supporting device is novel in design, firm in structure, capable of stably supporting the top andthe two sides of the roadway, high in safety, capable of adapting to the changeable roadway environment and convenient to use; the base can drive a supporting column structure to move, manual disassembling, assembling and carrying are not needed, the labor intensity is reduced, and the reinforced supporting device is worthy of popularization.
