[0002] A printing paver is a construction equipment mainly used for paving various materials (asphalt, concrete, etc.) on the base and surface layers of roads. It performs preliminary compaction and leveling while evenly spreading various materials on the road base. At present, the lifting device of the printing paver includes a boom and a lifting cylinder. The paving thickness is determined by the lifting height of the boom, and the lifting height of the boom is completely determined by the extension and contraction amount of the lifting cylinder. Therefore, it is difficult to achieve large thickness paving. For example, there is an existing Chinese utility model patent with patent number CN207143662 U, which discloses a paving thickness conversion device for a paver. Although the paving thickness of the paving thickness conversion device of the paver is increased, the range of the increase in paving thickness is relatively small.
