The invention provides a helicopter pillar type undercarriage which comprises an outer cylinder, an inner cylinder and an inner cylinder. One end of the rotating cylinder is connected with the outer cylinder, and the rotating cylinder can extend into the outer cylinder; the inner cylinder is connected with the other end of the rotating cylinder; wherein the inner cylinder can extend into the rotating cylinder; the anti-torsion arm assembly is arranged between the inner cylinder and the rotating cylinder; the outer cylinder is in butt joint with a machine body structure in a flange mode. A hole with the same diameter as the outer cylinder is formed in the machine body structure upper connector and can be matched with the outer cylinder to transmit heading and lateral loads. The undercarriage is connected with the lower connector through a flange at the bottom of the outer cylinder, the flange is fixed to the lower connector through a plurality of bolts, and course, lateral and vertical loads can be transmitted.
