The invention relates to a transfer vehicle for transporting a precast slab type track bed. The transfer vehicle comprises a frame (11) and a control device (10); a pair of axles (12) are arranged at the bottom of the frame, and wheel assemblies (13) are arranged at the two ends of each axle; the transfer vehicle is characterized in that a support frame assembly (1) is arranged on the frame (11) in the length direction, a sliding frame (6) is arranged on the support frame assembly, the sliding frame slides back and forth along the support frame assembly (1), the sliding frame is provided with at least one first driving device (4), the power output end of each first driving device is provided with a first gear (5), a first rack (2) is arranged on one side of each first gear and matched with the first gear in a meshed mode, and the first racks are arranged in the length direction of the frame. The transfer vehicle for transporting the precast slab type track bed has the advantages that when the precast slab type track bed is hoisted, the placing position of the precast slab type track bed can be adjusted, therefore, the transportation efficiency and adjustment efficiency of the precast slab type track bed are improved, and the construction cycle of a whole track is shortened.
