The invention provides a railway engineering vehicle-mounted lifting door device. The lifting door device is characterized in that a first hinge base, a second hinge base, a first safety pin base and a second safety pin base are arranged at the upper end of a door frame, the front end and the rear end of a first lifting hydraulic cylinder are hinged to the first hinge base and the second hinge base together, the front end and the rear end of a second lifting hydraulic cylinder are hinged to shaft heads of the two ends of a cross shaft at the left end of a lifting door together, a third hinge base and a fourth hinge base are arranged at the upper end of the first lifting hydraulic cylinder and the upper end of the second lifting hydraulic cylinder respectively, a fifth hinge base and a sixth hinge base are arranged on the borders of the two sides of the lifting door respectively, the front end and the rear end of a first turning-over hydraulic cylinder are hinged to the third hinge base and the fourth hinge base together, the front end and the rear end of a second turning-over hydraulic cylinder are hinged to the fifth hinge base and the sixth hinge base together, and a first guard railing and a second guard railing are installed on the borders of the two sides of the lifting door respectively. When the vehicle door is closed, safety pins are inserted into a hole in the first safety pin base and a hole in the second safety pin base respectively to lock the lifting door to the door frame of a compartment; an engineering vehicle vehicle-mounted hydraulic system provides power for the hydraulic cylinders in the lifting door device.
