[0008] From the automatic lifting system described above, it can be seen that the existing various devices have their own advantages and disadvantages, and the radar antennas carried are subject to certain restrictions. When the size of the antenna array is too large and a certain lifting height is required , the above-mentioned automatic deployment systems are not suitable for

Embodiment
[0038] see figure 1 , a hydraulic multi-link lift for radar antennas, including a turntable 1, a lower support 2, a middle support 3, a double-stage cylinder support 4, an upper support 5, a back frame 6, a position sensor 7 and a lift angle sensor 8.
[0039] The turntable 1 is rectangular, provided with a frame and reinforcing ribs, arranged horizontally, and the back frame 6 is a narrow and long rectangular frame structure, and one end of the turntable 1 is connected with a rotatable pin shaft at the lower end of the back frame 6 . The lower support 2, the middle support 3 and the upper support 5 are all equipped with oil cylinders and support rods, and are combined into a support mechanism. Two rows of the support mechanism and two double-stage support mechanisms are connected in parallel between the turntable 1 and the back frame 6. Oil cylinder support 4. The lift angle sensor 8 measures the lift angle of the back frame 6 , and the position sensor 7 measures the positi...

The invention discloses a hydraulic multi-link lifting mechanism for a radar antenna. The hydraulic multi-link lifting mechanism comprises a rotary table, lower supports, middle supports, two-stage cylinder supports, upper supports, a back frame, a position sensor and a lifting tilt angle sensor. One end of the rotary table and the lower end of the back frame are in rotatable pin connection. The lower supports, the middle supports and the upper supports are respectively provided with a cylinder and a support rod, and form support mechanisms. The two support mechanisms and the two two-stage cylinder supports are connected in parallel between the rotary table and the back frame. The lifting height of the lifting mechanism can reach 19.2 m, and load can reach 17 tons; the lifting mechanism is suitable for automatic lifting and accurate positioning of the large-array-plane radar antenna, and has very high wind-resistance stability; through a hydraulic drive mode, work efficiency of automatic lifting of the large-array-plane radar antenna is greatly improved; and through the lifting tilt angle sensor and the position sensor, reliability of automatic control is improved.
Description
technical field [0001] The invention relates to the technical field of radar antennas, in particular to the accurate positioning and wind resistance stability of automatic lifting of large-frontage radar antennas, in particular to a hydraulic multi-link lifting mechanism for radar antennas. Background technique [0002] Modern high-tech warfare has higher and higher requirements on the maneuverability of radar. Mobility refers to the ability of radar to quickly conceal or transfer, which involves the radar from one position to the working state, after being withdrawn and transported, entering another position to set up and enter the working state. And many other links. In order to complete the erection and withdrawal of the radar antenna, an automatic lifting mechanism is usually used to complete it. [0003] The automatic lifting system of the radar antenna is divided into two types of linkage mechanism and vertical mechanism in terms of structure, and three types of elect...
