The invention, which belongs to the related technical field of the power equipment, relates to a four-axis four-linkage uninterruptible-power multi-bypass-loop cable laying platform vehicle and a using method thereof. A platform vehicle comprises platforms; cable laying mechanisms are fixedly connected to the platforms; and the bottoms of the platforms are connected with pulleys by lifting rods. Each cable laying mechanism consists of a mounting seat fixedly connected with an X-axis linear sliding table; a Y-axis linear sliding table is installed on the X-axis linear sliding table; a Y-axis connecting block is installed on the Y-axis linear sliding table and is fixedly connected with a Z-axis linear sliding table; the Z-axis linear sliding table drives a connecting rod to carry out Z-axis movement; and the outer end of a Z-axis connecting rod is hinged to a cable roller. According to the invention, four direction adjustment of each cable roller is realized by using the three linear sliding tables and the lifting rods arranged vertically; and thus the cable roller can be adjusted properly during the cable laying process according to a relative included angle between a target position of the cable and the cable roller as well as the position change, so that the unnecessary friction damage can be reduced.
