Description

technical field

[0001] The invention relates to the field of engineering survey and detection, in particular to a novel locking and releasing device for a gyro theodolite. Background technique

[0002] The gyro theodolite can point out the true north direction at any point on the ground, mine or tunnel within the range of 75 degrees north and south latitude, and has a wide range of applications in engineering construction survey, ship manufacturing, and military aiming.

[0003] The existing gyro theodolite basically adopts the combination of the pendulum type gyro north finder and theodolite suspended by hanging wire. During use, the sensitive part of the gyro is lowered slowly. At present, when the sensitive part of the gyro is lowered and locked, the eccentric wheel locking device, the wedge locking device or the screw nut auxiliary locking device are basically used, and the manual operation, the error rate Larger, respectively, there are the following defects: the locki...
