Problems solved by technology
However, most of the existing two-axis stable tracking platforms are not equipped with mechanical locking devices, so that the platform azimuth frame and the motor are in a state of free movement all the time under the condition of non-working or ground maneuvering conditions. If the optical load is installed on the platform, large Moments of inertia and shocks can cause damage to the azimuth frame and motor
In addition, most of the existing two-axis stable tracking platforms do not have an electromagnetic locker that can be remotely controlled and electromagnetically locked to any position of the frame and then oriented to the target.

The invention provides a mechanical and electromagnetic locking conversion device for a direction frame of a two-axis stable tracking platform. The device is composed of a gear shifting adjustment part, a mechanical locking part, an electromagnetic locking part, a circumference rotary table part and a connection locking part. A multipurpose knob is pulled and pressed vertically and rotates circumferentially to finish adjusting three gears which are the free-running operation gear, the mechanical locking gear and the electromagnetic device locking gear, combination integration of mechanical locking and electromagnetic locking of the direction frame of the two-axis stable tracking platform is achieved, and manual mechanical locking and automatic electronic locking can be carried out on the direction frame. The diversity of function combinations is achieved by means of the structure, and the device is convenient to use, reliable and suitable for the stable platform requiring the multiple locking functions.
Description
technical field [0001] The invention belongs to the technical field of aerial remote sensing, is applicable to a low-altitude remote sensing two-axis stable tracking platform system, relates to an azimuth drive structure conversion device for mechanical locking and electromagnetic locking of an azimuth frame, and can be used for a two-axis stable tracking platform in non-working The mechanical locking of the frame under high-altitude or ground maneuvering conditions can also be used for electromagnetic locking of the frame during low-altitude remote sensing operations so that the effective optical load can be oriented to observe the target. Background technique [0002] The two-axis stable tracking platform is mainly used in low-altitude remote sensing systems. Its function is to keep the visual axis of the optical load mounted on it to follow and stabilize the set target. Commonly used optical payloads include various film cameras, real-time transmission cameras, visible li...
