The invention discloses a transportation vehicle for pipeline processing. The transportation vehicle comprises a base and a bracket. A placement box is arranged in the bracket. The left and the rightsides of the placement box are connected with the bracket through rotation shafts. A limiting plate is arranged at the upper end of the placement box. A plurality of placement grooves in which pressure plates are arranged are formed in the limiting plate. A plurality of sliding cavities corresponding to the placement grooves are transversely formed in the limiting plate. Threaded rods are arrangedin the inner parts of the slide cavities. The left ends of the threaded rods extend out of the placement box. The left ends of the threaded rods are provided with adjusting wheels. A plurality of sliding rods are arranged on each threaded rod. One end of each sliding rod is connected with the corresponding pressure plate. Sliding grooves allowing the sliding rods to slide therein are formed between the sliding cavities and the placement grooves. A dust collecting cavity is formed inside the base. The left end of the dust collecting cavity is provided with an air outlet on which a fan is arranged. A dust collecting pipe is arranged on the right side of the bottom of the dust collecting cavity. A dust collecting hood is arranged at the lower end of the dust collecting pipe. The transportation vehicle has a simple structure, is convenient to use, can transport conveniently, is wide in application range, and can clean the ground.
