Description

Large-caliber telescope supporting system and tracking frame
Technical Field
The invention relates to the structural design of a large-caliber telescope, in particular to a large-caliber telescope supporting system and a tracking frame.
Background
The mounting structure of the large-caliber telescope is also called a tracking frame structure, and the existing tracking frame structure has various structural forms, mainly including a horizontal type, a polar axis type, a horizontal type, a T-shaped frame structure, a six-rod universal platform type and the like. The first three structural forms are widely applied to structural design of the large-caliber foundation photoelectric telescope.
The three typical trackers differ greatly in structural design. The horizontal structure is single, two shafting forming the tracking frame are vertical to each other, the shafting vertical to the ground is called an azimuth shafting, and the shafting horizontally arranged and vertical to the azimuth axis is called a horizontal shafting (also called a pitch axis); the polar axis type tracking frame is also provided with two axes, namely a polar axis and a declination axis, wherein the polar axis is parallel to the zenith axis and points to the north pole; the horizontal tracking frame is also composed of two mutually perpendicular rotating shafts, one of which points to the north and south is called a warp beam, and the other is perpendicular to the warp beam and called a weft beam.
Taking the horizontal structure as an example, the pitch axis system generally consists of three parts: left stand, right stand and cross. In the large telescope, a left upright post and a right upright post both comprise a complete shafting. When the two components and the four-way component are integrated and then installed on the rotary table, due to the fact that factors such as unequal height of an installation plane and poor flatness exist, the axis of the installed pitching shaft deforms, and observation accuracy is lowered. It is also possible to have an effect on the bearing life of the pitch shaft if the deformation is large.
In order to solve the problem, conventionally, a bench worker and a detector are generally required to grind the upper surface of the rotary table together, and an autocollimator is used for real-time measurement so as to ensure that the directions of the axes of the shaft heads on the two sides are consistent. However, with the increasing aperture of the telescope, the span of the telescope tracking frame reaches the magnitude of more than 10 m. On one hand, the span is increased, so that the traditional detection means is difficult to reach the set precision; on the other hand, the large load capacity and span can generate considerable deflection under the action of gravity, so that the load of the motor can fluctuate greatly.
