Abstract

The invention relates to an antenna test rotary table, in particular to a mobile antenna test rotary table with a self-locking function. The mobile antenna test rotary table comprises a supporting frame, a handle, rotating wheels, a speed reducing mechanism and the like, wherein the handle is fixedly connected to the supporting frame, the four rotating wheels are rotationally connected to the supporting frame in a circumferential distribution mode, and the speed reducing mechanism is arranged on the supporting frame. According to the invention, when a tooth block is separated from a bevel gear, the bevel gear can be clamped by a sliding clamping strip, so that the bevel gear and a device on the bevel gear can be prevented from deviating under the action of transverse wind load, and the purpose of locking the antenna in time can be achieved.

Description

technical field [0001] The invention relates to an antenna test turntable, in particular to a mobile antenna test turntable with a self-locking function. Background technique [0002] The antenna test turntable is one of the main equipment used to test the performance parameters of the antenna such as pointing, gain, lobe width, and sidelobe level. The antenna test turntable is widely used in industry and military. The antenna test turntable can make the antenna Performing horizontal rotation and vertical pitch movement facilitates the antenna to cover the airspace in a wide range, so that the scanning function of the antenna can cover the entire airspace. [0003] Since the use environment of the antenna test turntable is outdoors, the existing antenna test turntable may encounter horizontal wind when it is in use, but under the action of the transverse wind load, the antenna transmitting surface is easy to shift, which affects the detection results, and the existing The a...
