The invention relates to the technical field of track laying equipment for maglev trains and particularly relates to a multi-functional track transporting and laying machine for a maglev train. The multi-functional track transporting and laying machine for the maglev train comprises a rack assembly, a power generation unit, an electric control system, a hydraulic power system and a stepping type walking mechanism. The stepping type walking mechanism is used for driving the rack assembly to carry out stepping moving on a track and is core equipment for the multi-functional track transporting and laying machine to achieve marching on the track, and the stepping type walking mechanism can make the rack assembly move on the track in the stepping mode, so that track transportation can be carried out through a newly-paved track, and fixation of the rack assembly on the newly-paved track can be achieved to complete track laying work. The rack assembly can be provided with multiple sets of track transporting and laying equipment to complete track transporting and laying. The multi-functional track transporting and laying machine for the maglev train improves the efficiency of constructionwork, reduces track laying equipment input, lowers manpower and material resource cost and reaches the purposes of comprehensively saving various cost and creating high economic benefits.
