Description
Technical Field
The invention relates to the technical field of gyro compass north-seeking measurement, in particular to a vibration-damping locking and unlocking device for a vehicle-mounted gyro compass.
Background
A gyro compass is a measuring device which is free of support and can automatically establish a north reference. The north-seeking working principle is as follows: the gyro compass is internally provided with a suspended gyro sensitive part, and generates a moment of precession to the north through the horizontal component of the rotational angular velocity of the sensitive earth under the action of gravity, so that a gyro main shaft (namely an H vector) swings around a meridian plane in a reciprocating way, and the true north direction is calculated through the conversion of optical signals and electrical signals after the reciprocating swing of the gyro main shaft, so as to achieve the purpose of north finding.
When the gyro compass works, a gyro sensitive part in the gyro compass is in a suspension state, and a stable rigid supporting base is needed at the moment; during transportation, although the gyro sensitive part is in a locking state, the gyro compass is required to be separated from the carrier body in a rigid connection state, so that the gyro compass is in a vibration reduction transportation state, and the damage to the gyro compass caused by vibration and impact of the vehicle-mounted rigidity-adjustable platform is avoided. The vibration reduction locking and unlocking device automatically completes the rapid conversion of the transportation and measurement states of the gyro compass on the same device, changes the traditional work mode of separation of transportation and measurement in the past, and improves the work efficiency and the maneuvering flexibility of the system. During transportation, the gyro compass is in a vibration damping transportation state through the loosening action of the vibration damping locking and unlocking device, so that the protection of the gyro compass is achieved; during measurement, the gyro compass is in a rigid connection state through the locking action of the vibration damping locking and unlocking device, and the purpose of north finding measurement is achieved.
In the past, the transportation and measurement of gyrocompasses are two operation modes under different environments. During transportation, the gyro compass is placed in a special packaging box to be protected. During measurement, the gyro compass is taken out of the special packaging box and is placed on the rigid support to be compressed and leveled, and then north seeking measurement is carried out. After the measurement is finished, the gyro compass needs to be replaced into the special packaging box after being disassembled so as to meet the transportation requirement.
The whole set of operation process of the prior gyro compass is complicated and time-consuming. Firstly, a rigid bracket (or a tripod) is erected, then the gyro compass is taken out from the special package and is installed on the erected rigid bracket (or the tripod), and north seeking measurement can be carried out after leveling. After the measurement is finished, the gyro compass needs to be placed back into the special packaging box. The operation is not only complicated, but also the equipment matching is complex, and the occupied effective space is large. This is a big drawback for the vehicle-mounted rigid adjustable platform itself that has high mobility requirement and limited carrying space.
The operation flow is complicated when accessories are equipped, the operation difficulty is increased virtually, and the requirements on operators are improved. The automation degree of the whole system is improved. The requirements of the whole set of system on flexible tacticity are not met, and the expansion of the application field of the system is hindered.
