The invention relates to a lift type upper platform structure of a trailer van. The lift type upper platform structure of the trailer van is characterized in that the lift type upper platform structure comprises a front upper platform, a rear upper platform and upper platform lifting mechanisms, wherein the front upper platform, the rear upper platform and the upper platform lifting mechanisms are connected with side sheets of a frame in a sliding mode, and the upper platform lifting mechanisms comprise the front upper platform lifting mechanism, the rear front platform lifting mechanism and the rear tail platform lifting mechanism; ascending and descending of the front end of the front upper platform are achieved through stretching and retracting of a front pulling oil cylinder and a rear straight ejecting multi-stage cylinder of the front upper platform lifting mechanism; the rear upper platform is driven to ascend and descend through stretching and retracting of a straight ejecting oil cylinder of the rear front platform lifting mechanism and an oblique ejecting multi-stage cylinder of a rear tail platform telescopic arm. According to the lift type upper platform structure of the trailer van, a second layer platform can be lowered more through application of steel wire rope and pulley block mechanisms, multi-stage cylinders and multiple sets of oil cylinders, the structure can be mounted on a vehicle more flexibly and compactly, and mixed mounting of commercial vehicles which are of different brands and have large size difference can be achieved.
