Method and device for non-interfering operation of fast reflecting surface hoisting and six-cable tug cabin entering port

Abstract

The invention discloses a method and a device for realizing non-interference operation of FAST reflecting surface hoisting and six-cable cabin dragging port entrance. The device comprises a feed source cabin operation support structure and a reflecting surface unit hoisting support structure, wherein the feed source cabin operation support structure is composed of a feed source support tower and a support cable; the reflecting surface unit hoisting support structure is composed of a cable crane and a central hoisting ring beam; the central hoisting ring beam comprises an upper layer ring beam and a lower layer ring beam which can be detached; the upper layer ring beam is provided with an open slot corresponding to the projection positions of six support cables when the feed source cabin enters a port; the support cables bypass the open slot, and can further descend to the feed source cabin to enter the port safely; the lower layer ring beam is lower than the anchoring part of the lower end of the support cable and the feed source cabin; the upper layer ring beam and the lower layer ring beam both can act as the connecting structure at the lower end of the cable crane, so that the mutual non-interference operation of the reflecting surface unit hoisting and the port entrance of the feed source cabin under different working conditions is met. According to the invention, the interference difficulty of the operation of the hoisting equipment and six-cable dragging cabin port entrance is solved maximally; the continuous operation of the reflecting surface unit hoisting is solved; the port entrance need of the feed source cabin is also met.

Description

technical field [0001] The invention relates to a method and a device for non-interfering operation between the hoisting of a FAST reflector and the entry of a six-cable towed cabin into a port. Background technique [0002] The Five-hundred-meter Aperture Spherical radio Telescope (FAST) built by the National Astronomical Observatories of the Chinese Academy of Sciences is the largest single-aperture radio telescope in the world. A new mode for giant radio telescopes. The overall technical indicators of FAST: the aperture is 500m, the radius of curvature of the reflective surface is 300m; the aperture of the lighting area is 300m, and the focal ratio f / D =0.467. [0003] The FAST active reflective surface is composed of ring beams, reflective surfaces, cable nets, actuators, ground anchors, etc. The cable net is installed on the ring beam with 2225 nodes, and about 4450 reflective surface units are installed on the cable net nodes to form a reflective surface, and each no...

Problems solved by technology

[0009] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a method for non-interfering operation between the hoisting of the FAST reflecting surface and the entry of the six-cable trailer into the port. The need to drag the feed cabin into the port solves the problem of interference between the two to the greatest extent; another object of the present invention is to provide a set of devices for implementing the above method
