Abstract
The invention discloses a plate turnover device for tunnel construction, and relates to the field of tunnel construction. The plate turnover device for tunnel construction comprises a plate body and a vehicle body, a turnover mechanism is arranged on the vehicle body and comprises two fixing blocks, fixing rods are arranged on the two fixing blocks, a movable plate is fixedly connected between the two fixing rods, threaded rods are connected to the two fixing blocks in an inserted mode, and L-shaped plates are fixedly connected to the two ends of the threaded rods. Two movable rods are hinged to the top of the vehicle body, movable rods are hinged to the movable rods, and a connecting rod is fixedly connected between the two movable rods. According to the plate turnover device for tunnel construction, firstly, two bolts are rotated to limit a plate body, an L-shaped plate is pushed to limit one of the fixed rods, then a rotating handle is rotated to enable a movable plate to rotate with the limited fixed rod as the center, and due to the fact that the fixed rods at the two ends of the movable plate can be limited by the L-shaped plate, the plate body can be conveniently overturned. And the movable plate can be overturned in two directions, so that the plate can be conveniently mounted.
