Abstract

The invention discloses a navigation locking device suitable for a photoelectric tracker. The navigation locking device mainly comprises a microprocessor provided with a locking / unlocking control module, a first relay assembly, a second relay assembly, a motor, a limit switch group and a locking / unlocking actuator having a switch gear, wherein the locking / unlocking control module controls the forward / reverse rotation of a motor through the first relay assembly according to a locking / unlocking instruction sent by an upper control computer; and when the limit switch group is triggered by the switch gear, a driving voltage of the motor is turned off through the second relay assembly and a locking / unlocking in-position signal is output to the micro processor. The navigation locking device solves the problem of automatic locking of mechanisms in the navigation or transportation process of the photoelectric tracker, has the advantages of simple structure, small volume, light weight, good adaptability, high reliability and the like, and can be used for not only the photoelectric tracker but also for the similar equipment having rotation mechanisms.

Description

technical field [0001] The invention relates to a locking device, mainly to a locking device suitable for a slewing mechanism, in particular to a navigation locking device suitable for a photoelectric tracker. Background technique [0002] The photoelectric tracker is a comprehensive photoelectric detection and tracking device that integrates various photoelectric sensors such as visible light, infrared, and laser. These photoelectric sensors are driven by the azimuth and pitch mechanism of the photoelectric tracker to complete the distance measurement and stable tracking of the target. In order to ensure the tracking accuracy, in general, the azimuth and pitch mechanisms of the photoelectric tracker are directly driven by DC torque motors to achieve their respective movements, and this type of mechanism often has a small frictional moment. When the photoelectric tracker is not working and is in a shutdown state and is sailing or transporting with the carrier, the movement o...
