A pneumatic trailer braking device for a full face tunnel boring machine comprises a control gas chamber, an adjusting rod, a braking block, a hinging connecting plate, a rocker arm, a brake frame body and a return spring, wherein the brake frame body is fixed at the lower part of a trailer B and close to a track; the control gas chamber is transversely placed on the brake frame body; one end of the rocker arm is hinged with the brake frame body; the other end of the rocker arm is hinged with a push rod of the control gas chamber; the adjusting rod is connected with the rocker arm and the braking block so as to adjust the braking block up and down; the hinging connecting plate is connected with the braking block and the brake frame body so as to adjust the braking block up and down; and the return spring is connected with the braking block and the brake frame body to reset the braking block so that the braking block is completely separated from the track. The invention is advantaged in that the pneumatic trailer braking device for the full face tunnel boring machine is simply structured and convenient to operate; the braking block is pressed on the track by means of the control gas chamber and a mechanical structure so as to generate a friction force and exert a braking effect; and the mechanism is safe and reliable and also convenient to maintain. The pneumatic trailer braking device for the full face tunnel boring machine, provided by the invention, is widely applied to the technical field of tunnel boring machines.
