The invention provides an air pressure type tension automatic compensation device which comprises an energy storage barrel, a bottom plate and a front cover are arranged at the front end and the rear end of the energy storage barrel respectively, a cylinder barrel is inserted into the energy storage barrel, an energy storage area is formed between the cylinder barrel and the energy storage barrel, an inflation valve for inflating the energy storage barrel is installed on the energy storage barrel, and the energy storage area is communicated with the cylinder barrel through a vent hole. A piston is connected into the cylinder barrel in a sliding mode, a middle seat is installed between the piston and the front seat, one end of the piston is connected with a telescopic rod, a guide sleeve is installed between the middle seat and the telescopic rod, an I-shaped sealing ring is installed between the front cover and the telescopic rod, and a tire type sealing ring is installed between the piston and the inner wall of the cylinder barrel. Air passes through the vent hole, the first through hole, the second through hole and the third through hole, an inner cavity of the tire type sealing ring, an outer cavity of the I-shaped sealing ring, an energy storage area and the cylinder barrel are connected into an integral air volume, the sealing principle of the tire type sealing ring and the I-shaped sealing ring of the piston rod is air pressure expansion type sealing, and the sealing effect is better.
