The fixed part is connected with the sliding wheel, and the sliding wheel drives the fixed part to move on the pipe gallery track. Two rotating arms are connected to two ends of the fixing part, and the rotating arms rotate by taking the connecting points of the rotating arms and the fixing part as centers. When the hanger rail type inspection robot normally operates, the fixed part drives the rotating arm to move on the pipe rack track, and the rotating arm is attached to the inner wall of the pipe rack track to guide the hanger rail type inspection robot to move; the rotating arms arranged at the two ends of the fixing part can play a role in guiding, so that the hanger rail type inspection robot can do not rotate and can move in two directions. When the hanger rail type inspection robot encounters an obstacle in the moving process, the rotating arm extends outwards, so that the rotating arm encounters the obstacle before the fixed part, and after the rotating arm encounters the obstacle, the rotating arm still moves under the driving of the fixed part, and at the moment, the rotating arm rotates outwards to pass over the obstacle along the outer surface of the obstacle; and the fixed part sets up in the orbital more outside of piping lane, and the barrier is less, and the unevenness that is track welding department is general protruding, so the fixed part can not contact the barrier, consequently the hanger rail formula patrols and examines the function that the robot can reach and cross track concatenation department unevenness, avoids the vibrations of fixed part to avoid the vibrations of movable pulley. When the rotor arm crosses the barrier, can outwards rotate the arm, the rotor arm can not oneself turn back original position, with the laminating of pipe gallery track inner wall, so set up the elastic component between rotor arm and fixed part, the elastic component can be with the rotor arm after the rotation pull back original position and the laminating of pipe gallery track inner wall.
