Antenna adjustment device

Abstract

The invention provides an antenna adjustment device. The device comprises a horizontal adjustment mechanism. The horizontal adjustment mechanism includes a drive device, a spur gear set, a bevel gear set and a transmission assembly. The drive device drives the spur gear set to rotate. The spur gear set is connected with the bevel gear set. The transmission assembly comprises a transmission shaft, a rack and a semi-circular gear. The transmission shaft is coaxially connected in series with the bevel gear set. The rack is engaged with the transmission shaft. The tooth surface of the semi-circular gear is engaged with the rack. The opposite surface of the tooth surface of the semi-circular gear is in the form of a tangent plane. The tangent plane of the semi-circular gear is fixedly connected with the baffle board of an antenna. The drive device drives the spur gear set to rotate around an X axis so as to drive the bevel gear set to rotate around a Y axis. The drive force of the bevel gear set is transmitted to the transmission shaft of the transmission assembly and the rack, and then the rectilinear motion along the Y axis is obtained. The rectilinear motion of the rack drives the semi-circular gear to swing along the X axis. The baffle board is driven to swing together with the semi-circular gear, so that the horizontal angle is changed. Based on the antenna electric adjustable way of the antenna adjustment device, the horizontal azimuth angle of the antenna is electronically adjusted. Therefore, the device is simplified in adjustment operation, simple, fast, low in cost and much higher in adjustment accuracy.

Description

【Technical field】 [0001] The invention relates to the communication field, in particular to an antenna adjusting device for realizing antenna level adjustment. 【Background technique】 [0002] During the use of the base station antenna, it is necessary to adjust the horizontal azimuth angle of the antenna and the downtilt angle of the phase shifter according to the needs. In the prior art, the adjustment of the horizontal azimuth angle and the downtilt angle of the phase shifter are separated, because for the The antenna adjusts the horizontal azimuth angle. The existing technology has not been able to achieve remote electronic control adjustment, and there is no corresponding adjustment mechanism. When the base station antenna needs horizontal adjustment in some special occasions, it is necessary for the installation worker to climb the tower to adjust. By loosening the installation components , and then turn the antenna to the desired azimuth, and finally tighten the bolts ...

AI Technical Summary

Problems solved by technology

The operation is complicated, and the whole operation process is not only time-consuming, difficult, time-consuming, but also expensive, high labor cost, high risk of work safety, and the accuracy of the adjustment angle is not high, it is difficult to control, and it is often adjusted many times It may not be better to adjust the angle

In addition, the adjustment of the downtilt angle of the phase shifter is operated separately, the two cannot be organically integrated, and the adjustment and control are more troublesome
