Embodiment Construction

[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] The feed cabin construction, docking and maintenance device provided by the embodiment of the present invention can be applied in any operation of feed cabin construction, docking and maintenance. figure 1 A structure of a feed cabin to which the embodiment of the present invention is applied is given as an example. Such as figure 1 As shown, the feed cabin 31 is mainly composed of a star frame 1, an AB collar 2, a static platform 3 of the Stewart mechanism, a driving branch chain 4 of the Stewart mechanism, and a dynamic platform 5 of the Stewart mechanism. A 1mm thick stainless steel plate is wrapped around the outer side of the star frame 1 as a skin, which plays the role of dustproof, rainproof and EMC shielding. The fu...

Abstract

The invention discloses a feed cabin construction, berthing and maintenance device. The device comprises a foundation, a cabin supporting device arranged on the foundation, pulley supporting devices on the foundation, and dynamic monitoring units arranged on an annular beam platform of the cabin supporting device. The cabin supporting device comprises fixing upright columns, lifting upright columns, the annular beam platform and the like. Each of the three pulley supporting devices comprises two large pulleys, one ground pulley, one lifting platform, two fixing supporting parts, four plug-pin mechanisms, an auxiliary facility and the like. Each of the three dynamic monitoring units comprises one laser range finder, one reflection plate, one video and the like. The device can meet the functional requirements of construction, debugging, port entering and berthing, departing and maintenance of a feed cabin and the requirement for connection of steel wire ropes and the feed cabin.

Description

technical field [0001] The invention relates to the field of radio telescope engineering, in particular to a feed cabin construction, docking and maintenance device. Background technique [0002] The Five-hundred-meter Aperture Spherical radioTelescope (FAST) is a major scientific device during the 11th Five-Year Plan period in my country. After completion, it will be the largest single-aperture radio telescope in the world. It has three independent innovations: using Guizhou The natural karst depression is used as the platform site; thousands of triangular units are laid in the depression to form a 500-meter spherical crown active reflection surface; a light six-cable dragging mechanism is used to drag the feed cabin to realize a cable drive, and at the same time, A, The B-axis mechanism and the Stewart platform perform secondary fine-tuning on the receiver position to achieve high-precision positioning of the telescope receiver. [0003] In the observation mode, FAST can co...
