Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0030] The optical load is sometimes set to a very long working focal length or replaced due to different work tasks, so that the optical load cannot rotate in a full circle on the U-shaped frame. After judging that the pitch axis of the theodolite is flying, use the servo control system to brake the servo motor. The braking stop will cause the optical load to bear a large inertial braking moment, which will damage the optical load and the U-shaped frame. Therefore, the present invention provides a theodolite anti-running electromechanical protection system to avoid damage to the U-shaped frame and the optical load.

Abstract

The invention provides a theodolite anti-galloping electromechanical protection system, and solves the problem that an optical load and a control system circuit are damaged due to the galloping condition of a pitch axis in the working process of a theodolite. The theodolite anti-galloping electromechanical protection system adopts a structural form of combining a normally-open single-friction-plate electromagnetic brake and a buffer energy absorption unit. The theodolite anti-galloping electromechanical protection system adopting the structural form has the advantages of being strong in energy absorption effect, avoiding structural rigid collision, being convenient to install and the like, and can further protect the servo control system and the optical load and improve the reliability of the system by being matched with braking motion of a servo motor in an auxiliary mode.

Description

technical field [0001] The invention belongs to the field of theodolite, and in particular relates to an electromechanical protection system for preventing flying cars of theodolite. Background technique [0002] Theodolite is a measuring instrument designed according to the principle of angle measurement to measure azimuth and elevation angle. [0003] A slip ring mechanism is installed on the azimuth axis of the theodolite, which can realize 360° unlimited rotation. The pitch axis of the theodolite carries an optical load and rotates within a certain angle, generally -5° to 185°. However, for the servo control system of the pitch axis of the theodolite, it often occurs due to problems such as program runaway, control algorithm singularity, and electromagnetic interference. In severe cases, the optical load will impact on the U-shaped frame of the pitch axis, causing the system structure Damage, the economic loss caused by equipment loss is often very high. [0004] The ...
