Gravity-center-adjustable multifunctional transport vehicle

The invention relates to the technical field of transportation of long and large parts of railway vehicles, and particularly relates to a gravity-center-adjustable multifunctional transport vehicle. The gravity-center-adjustable multifunctional transport vehicle comprises a vehicle underframe, four universal wheels with brakes, a limiting cross beam, two supporting seats, an angle adjusting seat and a limiting block. The transport vehicle has the beneficial effects that by adopting the transport vehicle, through cooperation of the limiting cross beam, the two supporting seats, the angle adjusting seat and the limiting block, adjustable gravity center self-balance is achieved so as to guarantee the transport reliability, and transport of long and large heavy materials of different specifications and different vehicle models is achieved; and existing to-be-transported materials and parts which are horizontally placed are changed to be vertically and obliquely placed on the transport vehicle, a transport space i
