Description

Technical Field

[0001] The utility model relates to an automatic lifting device for a vehicle-mounted direction-finding antenna, in particular to an automatic lifting device for a direction-finding antenna which is convenient for storing and transporting the direction-finding antenna and its cable, and belongs to the technical field of vehicle supporting equipment. Background Art

[0002] The direction-finding antenna has the function of determining the direction of the incoming electromagnetic wave, thereby determining the direction of the enemy's working radio communication transmission station. This makes the direction-finding antenna play an increasingly important role in the military field and has important significance for future wars. When the direction-finding antenna is working, it is generally raised to a certain height through a lifting rod, and then the direction-finding antenna is unfolded to achieve the work of the direction-finding antenna determining the direction of the incoming wave. After the work is completed, the direction-finding antenna is lowered and retracted through the lifting rod. Since the lifting rod of the direction-finding antenna is frequently raised and lowered during the test process and exercises, the multiple cables of the direction-finding antenna are also frequently raised and lowered, which can easily cause the cables to be entangled with each other and become messy, which is time-consuming and laborious for the staff to clean up. In addition, since the direction-finding antenna itself is connected by various pipes and has weak strength, and the cables are exposed outside, there is no protection for both on the existing lifting rod. During transportation, the direction-finding antenna and cables are easily damaged by contact with foreign objects. Utility Model Content
