Problems solved by technology
[0004] The disadvantages of the method of lightening the reflecting surface of the radio telescope and the method of adjusting the shape of the reflecting surface at any time are: the design of the active adjustment support mechanism of the panel is relatively complicated, the cost is high, the adjustable range of the reflecting surface is small; the design of the antenna back frame is complicated , the cost is expensive, and there is room for lightweight design

Embodiment 1
[0031] Example 1, in Figure 5 , Figure 6 and Figure 7Among them, three groups of parallel mesh steel wire ropes 4 each pass through the corresponding through holes at an angle of 60 degrees to each other on the mesh point mechanism 7, and the two ends are fixed on the surface mesh steel wire rope fixed beam 1 by adjusting bolts 2 and nuts 3 , forming a light reflective surface net. The surface net steel wire rope 4 is locked on the upper end of the dot mechanism 7 by locking screws 9 . The upper end of support arm shaft 13 is screwed on the bottom flange underside of dot mechanism 7, and panel support arm 6 is inserted into support arm shaft 13 from bottom to top, and this has just constituted so-called column hinge. The coupling flange 19 is fixed on the lower end of the support arm shaft 13 through the nut 12 to form the lower side baffle of the panel support arm 6 . On the upper surface of the panel support arm 6 ends, a joint bearing 10 is installed by a screw 11 (t...

A light reflecting surface panel support mechanism of a radiotelescopio is provided with a grid antenna frame carrier, which is characterized by that: three groups of steel wire ropes with identical spacing are arranged with an included angle of 60 degrees to each other, two ends of each steel wire rope being fixed to a veil fixed beam to form a net face of triangular net hole having a triangular panel thereon to form a reflecting face; each intersection of the steel wire rope is provided with a mesh point mechanism; each steel wire rope of all mesh points is held in adjacent mode to each other and penetration, allowing relative movement; a draw steel wire rope is connected to each mesh point, with an lower end fixed to a fixed beam of the draw steel wire rope; a panel support arm is fixed to each mesh point, which is arrange at lower side of the veil; three panel support arms on each mesh points keep identical pivot angle direction; one end of the panel support arm is connected to the mesh point through a hinge post of a rotary degree of freedom, while another end thereof is connected to the bottom of the triangular panel through a spherical hinge of three rotary degrees of freedom. Installation position points of three spherical hinges form a regular triangle.
Description
technical field [0001] The invention relates to a support mechanism device, in particular to a support mechanism for a light-duty reflective panel of a radio astronomical telescope, which is used for supporting the reflective panel of a radio telescope, and is especially suitable for light-weight reflectors whose reflective surface shape of a large radio telescope needs to be adjusted at any time surface realization. Background technique [0002] The support of the reflective surface of a radio telescope is generally a two-stage support structure of the antenna back frame structure and the reflective surface panel support mechanism, that is, the reflective surface is composed of multiple panels, and each panel is supported by the corresponding support mechanism on the antenna back frame structure. The panels of radio telescopes are mostly in the shape of isosceles trapezoid (the two bases are concentric arcs). Traditionally, support and adjustment mechanisms are installed on...
