Large-scale deployable radial rib antenna main/auxiliary rib node vertical height measurement system

Abstract

The invention provides a large-scale deployable radial rib antenna main / auxiliary rib node vertical height measurement system, belongs to the field of a large-scale antenna measurement device, and solves the problems existing in the assembly stage of a large-scale deployable radial rib antenna. The system comprises a horizontal base, a mark post, a level meter, a periscope and slide rails. The mark post, the periscope and the slide rails are vertically arranged on the horizontal base; the mark post and the slide rails are fixedly connected with the horizontal base; the level meter is arranged on the mark post; one vertical face of the mark post is provided with scales; an entrance of the periscope faces to the scales on the mark post; the left and right sides of the periscope are respectively provided one slide rail; the periscope is a multi-section positioning telescopic structure; each section of the periscope is in slide connection with the two slide rails; the upper end of the each section, except the bottommost section, of the periscope is in slide connection with the two slide rails; the two slide rails are fixedly connected with the mark post through a plurality of connection rods respectively; and the connection rods for enabling the two slide rails to be connected with the mark post are arranged in a mismatched manner. The system is used for vertical height measurement.

Description

technical field [0001] The invention belongs to the field of large-scale antenna measuring equipment, and in particular relates to a large-scale expandable radial rib antenna main and auxiliary rib node vertical height measurement system. Background technique [0002] The expandable radial rib antenna needs to measure and adjust its surface accuracy during the assembly stage. One of the important steps is to measure the vertical height of the main and auxiliary rib nodes, and use the measurement results as the original reference for adjustment; large expandable Some nodes on the primary and secondary ribs of the radial rib antenna have a height of more than five meters, which is difficult to measure with existing equipment, resulting in reduced assembly efficiency and affecting surface accuracy. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the surface precision adjustment process of the large-s...
