The invention relates to a foldable radar antenna lifting mechanism based on space link multi-oil-cylinder coordinated drive. The foldable radar antenna lifting mechanism based on space link multi-oil-cylinder coordinated drive comprises a first-stage parallel mechanism, an auxiliary turnover mechanism, a second-stage parallel mechanism, a supporting platform mechanism, a first rotary encoder, a second rotary encoder and a horizontal sensor, wherein the first-stage parallel mechanism is installed on the auxiliary turnover mechanism, the upper portion of the second-stage parallel mechanism is installed on the auxiliary turnover mechanism, the bottom portion of the second-stage parallel mechanism is installed on the supporting platform mechanism, the first rotary encoder, and the horizontal sensor are installed on the first-stage parallel mechanism, and the second rotary encoder is installed on the second-stage parallel mechanism. The foldable radar antenna lifting mechanism based on space link multi-oil-cylinder coordinated drive has the advantages that the control accuracy and the safety are high, the rigidity is high, the stability during lifting is better, the lifting capacity is great, the spreading and folding speed is fast, the space occupied by the mechanism after being folded is small, multiple transportation manners are compatible, and the contradictions between the lifting height and the lifting capacity and between the lifting height and the mobility are effectively solved.
