Loosing locking and power supply device of suspension wire type gyro north seeker

Abstract

The invention relates to a loosing locking and power supply device of a suspension wire type gyro north seeker. The loosing locking and power supply device is arranged at periphery of a lower part ofa gyro, several evenly distributed lifting pin components are used to hold the gyro tightly; the lifting pin components are driven by a transmission chain composed of a driving motor, a pinion and a loosing locking cam, and the loosing locking cam is supported by a ball located in a square type rail; the loosing locking cam is provided with a loosing locking stopping block, and a position detection device is composed of the loosing locking cam, and a sensor adjustment guide rail, a locking sensor and a loosing sensor all arranged on a motor mounting bracket. The loosing locking and power supply device is compact in structure, reduces system size and weight, and effectively avoids change to form of a gyro suspension tape caused by the conventional axial supporting type loosing locking device. A branch power supply device of the gyro is integrated in the lifting pin, a locking function and a power supply function of the gyro are completed by one mechanism, thus, structure design is simplified, a problem of cooperativity of the loosing locking device and the branch power supply device are solved effectively, and reliability of the system is improved.

Description

technical field [0001] The invention relates to the technical field of inertial navigation equipment, in particular to a locking and releasing device and a power supply device for a wire-suspended gyro north finder. Background technique [0002] The suspension wire gyro north finder is a kind of orientation equipment. Its working principle is: use an elastic metal wire to hang a gyroscope sensitive part (hereinafter referred to as gyroscope) with a high-speed rotating gyroscope motor inside. The external torque generated by the hairspring etc. is balanced, and the gyroscope reciprocates and precesses around the meridian plane. The angle of precession is measured by an optical or photoelectric sensor, and the true north direction is calculated. The gyroscope is suspended from the frame by wires. When orienting, firstly the gyroscope is locked. When starting the gyroscope, power is supplied to the gyroscope through the bypass contact and the conductive hairspring at the same...

Problems solved by technology

[0003] The locking and loosening of the existing wire-suspended gyro north-seekers mostly adopt the axial lifting and lowering type, which not only takes a long time to lock and loosen the action, but also has a large related structure size, and more importantly, the lifting action of the gyroscope is easy to cause The suspension belt is in a bent state, resulting in obvious changes in the stress state and shape of the suspension belt, which makes the zero stability of the sy
