Problems solved by technology

However, separate transportation will cause the following problems: it will inevitably increase the installation time and greatly prolong the deployment time of the entire radar system; separate transportation will put forward higher requirements for the accuracy and reliability of the antenna skeleton deployment mechanism
[0004] The existing antenna framework deployment schemes are mostly manually installed and disassembled. Multiple load-bearing rods are installed and locked separately. Although this method has high reliability, it is time-consuming and laborious to install, and the deployment time is very long. Can no longer meet the needs of modern warfare

Abstract

The invention relates to the technical field of vehicle-mounted military radars, in particular to a vehicle-mounted external illuminating radar antenna framework folding and unfolding mechanism. The adapted size range of the antenna aperture is relatively wide and antenna bearing rods are not limited in length and number; a traction mechanism realizes motion transmission among the antenna bearing rods, so that a driving mechanism only needs to be arranged on one bearing rod and the space is saved while the driving mechanism is simplified; a locking mechanism is simple to operate, and the bearing rods can be locked by one-step operation, so that large amounts of time and manpower costs are saved; in the locking mechanism, a taper pin is in conical fit with a taper pin seat, so that compared with a cylindrical surface, the situation of jamming caused by coaxiality can be avoided; a supporting arm is mounted on a main supporting frame; a driving apparatus is arranged on the edge of the supporting arm and connected with the antenna bearing rods; the traction mechanism is connected with the antenna bearing rods; and a guide apparatus and the locking mechanism are located between the supporting arm and the antenna bearing rods.

Description

technical field [0001] The invention relates to the technical field of military vehicle-mounted radar, and more specifically relates to a vehicle-mounted external radiation source radar antenna skeleton folding mechanism. Background technique [0002] High mobility is one of the key technical indicators of ground vehicle radars. In recent years, high mobility radars are mainly based on radars with small-caliber antennas. With the needs of information warfare and the development of radar detection technology, in order to detect incoming targets in advance and improve the detection distance, large-scale planar array antennas have been widely used in ground medium and long-range three-coordinate military radars. Due to the limitations of carrying capacity and transportation conditions, large planar antennas must be processed in blocks to meet cross-country transportation requirements. Therefore, in the process of radar erection, it is necessary to carry out links such as anten...
