Spatial structure balance weight device for reflector antennas

Abstract

The invention discloses a spatial structure balance weight device for reflector antennas, which relates to a design technology of a balance weight device for reflector antennas in the fields such as communication, measurement and control, and radio astronomy. The invention aims to provide a balance weight structure which has high rigidity and is light, easy to install and suitable for mass production. The balance weight device includes counterweight bodies, main supporting rods, a cross beam, vertical supporting rods, lateral supporting rods, lateral lower supporting rods, lateral upper supporting rods, inner supporting rods, ball joints, and the like. The shape of the counterweight device is symmetric. The two counterweight bodies are supported by a number of rods to form a stable spatialstructure. The spatial rods are connected with the counterweight bodies by bolt balls. The balance weight device has the characteristics of high structural rigidity and low weight, can balance part of wind load, reduces the disturbance of wind load to antennas, improves the operation accuracy of the antenna system, and is especially suitable for the balance weight structures in large and medium-sized reflector antennas.

Description

technical field [0001] The invention relates to the technical field of large and medium-diameter reflector antennas, in particular to a spatial structure balance weight device for reflector antennas. Background technique [0002] Reflector antennas used in the fields of communication, measurement and control, and radio astronomy must have a pitch function, and the pitch axis should coincide with the center of gravity of the pitch rotation part, so that the pitch moment of inertia and pitch wind moment are small. However, in the design process, it is generally impossible for the position of the center of gravity of the pitching and rotating part to coincide with the pitching axis. [0003] In order to reduce the load on the driving device and reduce the servo error, a balancing device is usually required. The traditional method is to install the balance weight in the box of the pitch device or place the balance weight on both sides of the pitch gear, so that the pitch rota...

AI Technical Summary

Problems solved by technology

[0005] (2) Low stiffness

Since the pitch gear is a plane structure, when the counterweight is placed on it, it will increase the load of the gear and reduce the rigidity of the gear, thus affecting the accuracy of the transmission system

[0006] (3) Difficult to adjust

This utility model patent is only applicable to X-Y mounts of small-diameter reflector antennas, but not applicable to widely-used A-E mounts, especially large and medium-diameter reflector antennas

[0009] (2) Only the X axis is balanced

[0012] (1) Unable to connect to the reflector antenna

The methods provided by the above two utility model patents are only applicable to rod antenna forms such as base stations, and cannot be connected or matched with reflector antennas

[0013] (2) Not suitable for reflector antennas that rotate

The reflector antenna needs to move in pitch during work. The counterweights mentioned in the above two utility model patents are connected to the building through brackets or bases, and the pitching motion cannot be realized, so it is not suitable for rotating motion. reflector antenna
