Embodiment Construction

[0013] The present invention comprises a reflector made up of a base, a plurality of regular hexagonal reflector units 1 (in the field of large radio astronomical telescopes, currently used reflector units are regular hexagonal reflector units), because the reflector Unit 1 is a regular hexagon, so any reflective surface unit shares the vertex 4 with other reflective surface units; it also contains guiding and restraining branches and multiple active branching chains equal to the number of reflecting surface units. The active branch chain is located below the vertex 4 on the reflective surface, and there is an active branch chain at an interval of a vertex. The active branch chain includes an active telescopic drive rod 6, a support seat 5, and three support rods 3, each support rod 3 is two The end is connected to the spherical hinge 2, and since the adjacent reflective surface units share the same vertices, the three support rods on one supporting base are connected to the su...

Abstract

Large radio astronomy telescope co-driving parallel connection array mechanism belongs to physical construction designing technology field, in particular relating to co-driving parallel connection mechanism array having strong coupling character. It featuring that: each unit lower end connected with base through guiding constraint branched chain for restricting reflection plane unit rotating at horizontal direction, one active branched chain located below all nonadjacent peak, through one telescopic link flex action to control above three reflection plane units cooperation movement. The present invention can realize reflection plane long range matching movement on occasions of reducing drive motor number.

Description

technical field [0001] The co-driven parallel array mechanism of a large radio astronomical telescope belongs to the technical field of mechanical structure design, and in particular relates to a co-driven parallel mechanism array with strong coupling characteristics. Background of the invention [0002] In the process of human beings exploring the universe, large telescopes are indispensable tools. Not only that, large telescopes also play an irreplaceable role in fields such as earth environmental issues, solar physics, and military affairs. It is precisely based on the importance of large telescopes that countries are competing to build large astronomical telescopes. For example, Canada’s LAR (Large Adaptive Reflector) plan is preparing to build an innovative 300-meter-caliber radio telescope, and Europe is preparing to spend 2 billion US dollars to build a 100-meter-caliber giant optical telescope. . Currently the world's largest radio telescope is the 305-meter-calibe...
