The invention provides a front part buffer device for a semi-trailer transport vehicle. An inner cylinder barrel is divided into a gas cavity and a liquid cavity through a floating piston; one end of the liquid cavity is fixedly connected with a piston rod of an outer cylinder barrel through a piston head part; the liquid cavity is communicated with an oil liquid cavity of the outer cylinder barrel; the outer wall of the outer cylinder barrel is fixedly connected with a frame; the piston rod is connected with a saddle through a saddle pin shaft; two damping leakage holes running through the upper end lower ends are formed in the piston head part; and the opening directions of the two damping leakage holes are opposite. The front part buffer device for the semi-trailer transport vehicle not only meets the requirement for transportation smoothness of the semi-trailer transport vehicle, but also can be used for the traction of a semitrailer tractor, has a good buffering and damping effect and can meet the requirement for a lifting function of the transport vehicle.
