Embodiment Construction

[0016] Further description will be made below in conjunction with drawings and embodiments.

[0017] Such as Figure 1 ~ Figure 3 As shown, this embodiment includes a vertical antenna support 1, three poles 2, three plate antennas 3 and matching antenna pitch mechanism 4 and antenna swing mechanism 5, and the vertical antenna support 1 is a welded structural member , the cross-section is hexagonal cylindrical, welded by six plates with large waist circular holes 11 in rows on the surface, which can reduce the weight of the vertical antenna support 1.

[0018] Three plate antennas 3 are upright and evenly distributed on the outer periphery of the vertical antenna support 1 , and each plate antenna 3 is connected to the pole 2 through an antenna pitch mechanism 4 . The antenna pitching mechanism 4 comprises an upper hinged arm 41, a lower hinged seat 42 and a push-pull oil cylinder 43 between the upper hinged arm 41 and the lower hinged seat 42, and the upper hinged arm 41 incl...

Abstract

The invention discloses a plate-like antenna adjustment device which comprises a vertical antenna support seat, a plurality of holding poles, a plurality of plate-like antennas, a plurality of antenna pitching mechanisms and a plurality of antenna swinging mechanisms, wherein the plate-like antennas are vertically and evenly distributed at the periphery of the vertical antenna support seat; each plate-like antenna is connected with each holding pole by each antenna pitching mechanism; the lower ends of the holding poles are supported on a lower horizontal extension plate arranged at the bottom of the vertical antenna support seat; the antenna swinging mechanisms are respectively arranged on the top of the vertical antenna support seat, and comprise azimuth-drive motors and worm gear reduction gearboxes; and the upper ends of the holding poles pass through an upper horizontal extension plate and shaft sleeves arranged in the worm gear reduction gearboxes, and are fixedly connected with a worm gear. The plate-like antenna adjustment device is compact in structure and reliable in work. The plate-like antenna adjustment device realizes the adjustment for the plate-like antennas within two degrees of freedom, so that the directions of the plate-like antennas are aligned with a base station antenna, and the best communication effect between a base station and a communication van can be obtained. After the plate-like antenna adjustment device is adopted, a person does not need to get up to the top of a carriage for manual operation, so that the safety of plate-like antenna adjustment can be improved, and the working efficiency is increased.

Description

technical field [0001] The invention relates to a device for adjusting an antenna azimuth angle, in particular to a device with two degrees of freedom for automatically adjusting an antenna azimuth angle, which belongs to the technical field of antenna structures. Background technique [0002] The plate antenna is generally installed on the communication car for use. When in use, it is lifted out of the top of the car, and when not in use, it is stored in the car. After the communication vehicle arrives at the destination, the plate antenna rises out of the top of the car, and the plate antenna is aligned with the direction of the base station antenna after swinging around the Z-axis or Y-axis to maintain normal communication with the base station. The existing plate antenna adjustment device can only manually control the swing of the plate antenna around the Z-axis or the Y-axis, and the operator must climb on the top of the carriage to manually adjust the azimuth of the pl...
