Abstract

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.

Description

Technical field: [0001] The invention relates to a radar antenna lifting mechanism, in particular to a folding lifting mechanism, in particular to a folding radar antenna lifting mechanism based on the coordinated drive of multiple cylinders of space linkages. Background technique: [0002] The high-mobility low-altitude radar is mainly used to detect low-altitude targets and low-altitude blinding of the air defense network. When this type of radar is in the working state, in order to achieve the low-altitude detection function, the antenna needs to be elevated; The lifting mechanism is folded to realize compatibility with various transportation modes. [0003] At present, the structure of antenna lifting mechanisms at home and abroad is mainly divided into two categories: one is the folding antenna lifting mechanism represented by the "Giraffe" series radar of SAAB in Sweden and the RAC 3D radar of Thales in France. This type of lifting mechanism has good rigidity and stab...
