Hydraulic-drive movable bridge

The invention discloses a hydraulic-drive movable bridge. The hydraulic-drive movable bridge comprises a bridge steel body, a riverway, mounting bases, supports, oil cylinders, support columns, buzzermounting racks, mounting grooves, travel switches, hydraulic transmission systems and well slots and is characterized in that the mounting grooves are symmetrically formed in two sides of the riverway, one mounting base is mounted on one side, away from the riverway of each mounting groove, one support is mounted on the upper surface of each mounting base through bolts, each support is rotatablyconnected with the corresponding end of the bridge steel body, one oil cylinder is rotatably mounted at the bottom of each mounting groove, and the top end of each oil cylinder is rotatably connectedwith the bridge steel body. The hydraulic-drive movable bridge has the advantages that the opening and closing the movable bridge are controlled through the hydraulic ejector pins of the hydraulic transmission systems, the open
