The technical scheme of the utility model is:
A kind of hydraulically powered collapsible radar antenna elevating mechanism; It comprises base 1, the first active elevating lever 4 and the first passive elevating lever 3; It is characterized in that described first initiatively the lower end of elevating lever 4 and the first passive elevating lever 3 all cut with scissors and be contained on the base 1; The upper end of the first active elevating lever 4 and the bottom mid point of trapezoid support 5 are hinged and connected; An end on base links to each other on the upper end of the first passive elevating lever 3 and the trapezoid support 5, first initiatively elevating lever 4 be hinged and connected with the piston rod that the lower end hinge is contained in the main hydraulic cylinder 2 on the base 1; Also be hinged with secondary hydraulic cylinder 8 on the bottom of described trapezoid support 5; The piston rod of secondary hydraulic cylinder 8 and second initiatively elevating lever 7 is hinged and connected; The one end hinge of the second active elevating lever 7 is contained on the other end on base on the trapezoid support 5; Second initiatively the other end and the antenna pedestal 9 of elevating lever 7 be hinged and connected, antenna pedestal 9 also is hinged and connected with an end of the second passive elevating lever 6, the lower end of the second passive elevating lever 6 also is hinged and connected with trapezoid support 5 bottoms.
Be connected with between the last base of described trapezoid support 5 and the bottom and a reinforcement that the waist limit is parallel.
The described first active elevating lever 4 and the first passive elevating lever 3 are double-rod structure, and their two ends all link to each other through pivot, and pivot is installed in the corresponding hinged seat again.
The beneficial effect of the utility model:
The utility model adopts two groups of parallel four-bar linkages, thereby has realized folder function.Compare with the conventional elevator structure, lifting travel is big, it is little, in light weight to take up room, and lifting process guarantees that the radar height is motor-driven, high reliability and long-time continuous stable work steadily, fast.
The hydraulic drive system of the utility model is compared with the electromechanical drive system; Under the condition of the same power of output, volume and quality can reduce a lot, and bearing capacity is big simultaneously; Can accomplish the overhead of big weight radar antenna; And adopt hydraulic drive also can simplify mechanical structure greatly, thereby reduce the number of component of machine, also be convenient to realize automatic control.
