Installing and regulating method and device of parabolic antenna sample plate

Abstract

The invention discloses installing and regulating method and device of a parabolic antenna sample plate. A bracket is provided with a work table; the work table is provided with a hollow shaft; an antenna pedestal is sleeved on the hollow shaft; the upper end surface of the hollow shaft is provided with a spring; a first thrust bearing is arranged on the spring; the parabolic antenna sample plate is positioned above an antenna; a shaft of the parabolic antenna sample plate penetrates through the first thrust bearing, the spring and the hollow shaft; the lower end part of the sample plate shaft is a threaded segment; a second thrust bearing supports against the lower end surface of the hollow shaft; and the threaded segment is sleeved with a regulating nut; the spring is pressed and released to regulate a gap positioned between the detecting surface and the antenna reflecting surface of the parabolic antenna sample plate by rotating the regulating nut, and then a filler gauge is filled into the gap to detect the antenna reflecting surface. The invention is especially suitable for the installation and the regulation of the parabolic antenna sample plate and has the advantages of enhanced antenna installation efficiency, reduced labor intensity, high regulating accuracy, strong generality, and the like.

Description

technical field [0001] The invention relates to an installation adjustment method and a device thereof, in particular to an installation adjustment method and a device for a parabolic antenna template used in the detection process of an antenna reflection surface. Background technique [0002] A paraboloid is a curved surface obtained by rotating a parabola 180° about its axis of symmetry. The parabolic antenna is an antenna whose reflecting surface is a rotationally symmetrical paraboloid, that is, the reflecting surface of the antenna is a paraboloid. In the project, it is required that the reflector of the antenna exactly matches the paraboloid of the original design, so as to ensure that the performance index of the antenna meets the design requirements. During the manufacture, transportation and installation of the antenna, the reflective surface of the antenna is often damaged, and the reflective surface will be deformed, so that the reflective surface of the antenna ...

AI Technical Summary

Problems solved by technology

In this existing method, the gasket needs to be disassembled and assembled many times. During disassembly, the heavy sample needs to be hoisted repeatedly, and the gasket needs to be processed many times. It usually takes 1 to 1.5 hours to complete the adjustment of the detection gap of an antenna when the gasket is scrapped. There are problems such as multiple disassembly and assembly, low work efficiency, time-consuming, labor-intensive, and easy waste of materials; due to different antennas There are differences in the size of the base of the antenna. The gasket suitable for one antenna may not be suitable for the next antenna or the next batch of antennas. It needs to be reprocessed to make a gasket with a suitable size. The versatility of the gasket is relatively poor.
