Road transition automatic lifting device for governing bump at bridgehead

The invention discloses a road transition automatic lifting device for governing bump at a bridgehead. The device comprises a transition road plate, a control panel, a hydraulic machine, a cylindricalcontactor, a safety alarm lamp and an electromagnetic relay, when sedimentation occurs, the transition road plate is subjected to compressive force and transmits information to the control panel fixed below, meanwhile, the hydraulic machine is started to push the cylindrical contactor to make contact with the control panel and support the transition road plate, the hydraulic machine keeps the original height, the transition road section of the whole road surface and the bridge surface becomes smooth, and the electromagnetic relay is installed in the automatic lifting device and used for controlling signals sent by the safety alarm lamp. The height of the transition road plate is automatically adjusted mainly through the automatic lifting device, the roadbed and the bridgehead are effectively connected in sequence
