Problems solved by technology

However, as the aperture of large telescopes becomes larger and larger, the volume and weight of the telescope increase, and the moment of inertia of the azimuth shaft system becomes larger and larger. The traditional spring buffer limit structure cannot absorb the kinetic energy of the azimuth rotation, and cannot realize Meet the functional requirements of mechanical limit

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] The invention discusses a safety braking protection structure for the azimuth axis of the large-diameter telescope. When the azimuth axis of the telescope needs to be braked, the disc brake is activated to clamp the brake ring on the base to complete the braking of the azimuth axis of the telescope.

[0023] Such as figure 1 Shown is an assembly diagram illustration of the azimuth axis safety braking protection structure of the large-aperture telescope.

[0024] First of all, the interior space of the azimuth axis system of the telescope is relatively large, which can provide the installation position of the azimuth axis safety brake protection structure, and the staff can enter the interior of the azimuth axis system through the base 1, which is convenient for installation and maintenance. dynamic protection structure;

Abstract

The present invention discloses a heavy-calibre telescope azimuth axis safety braking protection structure. The structure design employs a disc-type brake structure. The disc-type brake structure is located in a telescope azimuth axis system, four sets of disc-type brakes are hung upside down on a rotation table on the telescope azimuth axis system and are uniformly distributed in a peripheral direction. When the telescope azimuth abnormally works, the system starts the disc-type brakes, the four sets of disc-type brakes synchronously clamp the brake rings on the telescope pedestal to force the telescope azimuth axis system to stop rotation. With the bigger heavy-calibre telescope caliber, the volume of the telescope is increased, the weight of the telescope is increased, and the rotational inertia of the orientation axis system is bigger. The heavy-calibre telescope azimuth axis can cause serious influence on important optical electron components such as a primary mirror, the orientation and the pitching axis system important component safety, so that the orientation axis safety brake protection design is very important. The structure has a remote control capacity and is simple instructure and safe and reliable.

Description

technical field [0001] The invention relates to the technical field of mechanical safety brake protection, in particular to a safety brake protection structure for an azimuth axis of a large-diameter telescope. Background technique [0002] Most of the large-aperture telescopes adopt the horizon-level telescope frame structure, and the pitch axis and the main lens tube assembly are fixedly installed on the azimuth axis, and the tracking and measurement of the target are realized through the rotation of the azimuth axis and the pitch axis. Usually, a spring buffer is installed in the azimuth shaft as a mechanical buffer limit to prevent the azimuth shaft from rotating beyond the working range and causing damage to important components and electric control system circuits. However, as the aperture of large telescopes becomes larger and larger, the volume and weight of the telescope increase, and the moment of inertia of the azimuth shaft system becomes larger and larger. The t...
