Embodiment Construction

[0023] The concrete implementation method of the present invention is as follows:

[0024] Such as figure 1 As shown, the present invention includes an arc-shaped scale bottom case 1, two movable slide covers 5, two limit-fixed bottom blocks 2, two limit-fixed bolts 6 and two limit stop posts 4; When the limit set bolt 6 is loosened, the movable sliding cover 5 assembled on the upper surface of the arc-shaped scale bottom case 1 can slide freely along the surface of the scale bottom case within the range of -90°~+90° attitude angle; the inverted T-shaped chute The limit tight bottom block 2 in 1-2 is connected with the moving sliding cover 5 through the limit fastening bolt 6, and the limit tight bottom block 2 can be placed in the inverted T-shaped chute 1-2 of the arc-shaped scale bottom shell 1 Sliding freely within the cross section; when the predetermined limit angle is reached, tighten the limit fixing bolt 6, at this time, the upper surface of the limit limit fixing bo...

Abstract

A limit mechanism for a stable platform with an adjustable attitude range, which includes an arc-shaped scale bottom case with a chute, two movable slide covers with scale windows, two limit-fixed bottom blocks, and two limit-fixed Bolts and two limit stoppers; the limit mechanism is used in pairs, and the bottom shell of the scale is fixedly connected with the inner side of the side plate of the azimuth frame of the stable platform through five fixing bolts; The surface of the shell slides freely; when the predetermined limit angle is reached, the limit set bolt is tightened, and the limit stopper becomes a limit stop, which prevents the maximum attitude angle movement of the pitch frame; the present invention can realize stable platform pitch frame attitude range Adjustable and precise limit, and use the sliding scale window to read the angle indication; it has the characteristics of simple and flexible operation, large applicable angle range, stepless change of limit angle, compact structure, etc., suitable for aviation remote sensing, target tracking and other servos Execution structure.

Description

technical field [0001] The invention belongs to the technical field of aerial remote sensing, and relates to a stable platform limit mechanism with adjustable attitude range, which can be used for precise and adjustable limit and protection of the stable platform frame, and has the advantages of simple and flexible operation, large applicable angle range, and adjustable limit angle. With the characteristics of stepless change and compact structure, it is suitable for inertial execution structures such as aerial remote sensing and target tracking. Background technique [0002] The stable tracking platform is one of the key equipment of aerial remote sensing. Its main function is to isolate the carrier disturbance, so that the optical axis (Line of Sight, LOS) can keep tracking the target stably in the inertial space according to the position command output by the host computer. In the servo state, the stable tracking platform LOS tracks the movement changes of the target in s...
