A connecting device for hanging

Abstract

The invention discloses a connection device used for hanging. The connection device comprises a screw rod, a nut, a round tube, a U-type clamping block, a first positioning screw, a second positioning screw, a plane antenna, a steel wire rope and a hanging ring screw rod, wherein the screw rod is connected with the U-type clamping block and the round tube, the nut is connected with the screw rod, the U-type clamping block and the round tube are locked and positioned through the nut, the U-type clamping block supports the lower frame of the plane antenna, the first positioning screw is connected with the U-type clamping block and is connected with the side frame of the plane antenna, the second positioning screw is connected with the U-type clamping block and makes contact with the upper frame of the plane antenna, a threaded hole is reserved in the side frame of the plane antenna, the steel wire rope is connected with the hanging ring screw rod, and the hanging ring screw rod is connected with the U-type clamping block. The connection device is simple and reliable in structure, easy to disassemble and assemble, capable of completely eliminating additional moment of force produced by a hanging device for a product and capable of effectively protecting the product, and meets requirements of assembling integration and test operations of the large heavy-load plane antenna in a horizontal state.

Description

technical field [0001] The invention relates to the technical field of spacecraft planar antennas, in particular to a connection device for hanging a planar antenna when it operates horizontally. Background technique [0002] Spacecraft planar antennas have the characteristics of large weight, large area, and large size, and work in a microgravity state on orbit. At present, when the spacecraft planar antenna is integrated and tested on the ground, it is usually in a vertical state, that is, the antenna plane is perpendicular to the ground. In order to balance the influence of the antenna’s gravity, the air cushion is mainly installed under the side frame of the planar antenna to eliminate the effect of gravity. Install the hanging device above the side frame to protect the product. However, for the horizontal operation of the planar antenna, the relevant hanging devices are rarely involved, and the existing hanging devices are directly connected to the side frame of the ...

AI Technical Summary

Problems solved by technology

However, for the horizontal operation of the planar antenna, the relevant hanging devices are rarely involved, and the existing hanging devices are directly connected to the side frame of the planar antenna, which will generate a large additional moment on the product itself. The device and the antenna are connected by threads, and stress concentration is easily formed at the connection, causing local damage to the product
