and the second action: the lifting mechanism (3) controls the whole self-walking track laying device to move downwards, when the track is in contact with the ground, the lifting mechanism (3) continues to control the base (6) to leave the ground to be suspended, the walking wheel set (7) rotates in the positive direction of the moving direction, and the self-walking track laying device is driven to move to a preset position;
and repeating the first action and the second action to automatically lay the track and walk.
9. A self-propelled rail laying apparatus according to claim 1, wherein when the self-propelled rail laying apparatus is required to turn, the following actions are performed:
and action three: the base (6) is erected on the ground, the lifting hook mechanism (8) clamps a rail to be laid, the lifting mechanism (3) controls the whole self-walking rail laying device to move upwards, and when the rail is lifted to be separated from the ground and suspended, the transverse moving mechanism (5) transversely moves to a turning position;
and fourthly, action: the lifting mechanism (3) controls the whole self-walking track laying device to move downwards and descend until the track contacts the ground;
and repeating the third action and the fourth action to carry out turning laying of the track and turning movement of the self-walking track laying device.
