A liftable plate turnover
machine comprises a
machine frame and a turnover mechanism. The
machine frame comprises a first cross beam, a first longitudinal beam, supporting legs and a
cushion frame. The turnover mechanism comprises a cylinder body, a first shaft, a turnover power hinge seat, a first turnover frame, a second turnover frame and a second cross beam. The first overturning frame comprises a second longitudinal beam, a stand column, a push plate oil cylinder plate, a
hydraulic cylinder body, a
piston rod, a rubber disc, an overturning frame support and a buffer block. One side of the first overturning frame is connected with a
hydraulic cylinder body through a push plate oil cylinder plate, the other side of the first overturning frame is connected with a rubber disc through a
piston rod, and the bottom of the first overturning frame is fixedly connected with the rack through an overturning and twisting seat. The push plate oil cylinder plate, the
hydraulic cylinder body, the
piston rod and the rubber disc form a lifting device to control the height of the hollow New Jersey guardrail. According to the liftable plate turnover machine, the turnover angle and position can be accurately controlled, and the stability and safety of a hollow New Jersey guardrail in the transfer process are ensured.
