A new type of locking and releasing device for gyro theodolite

Abstract

The present invention is a new gyro theodolite locking device, relates to the field of engineering measuring detection, and particularly relates to a new gyro theodolite locking device, comprising a base, the base is fixedly connected with a lifting device, a transition seat is arranged above the lifting device, the transition seat is provided with a convex plate, the convex plate is connected with a locking cup, the locking cup is a carrying platform, the upper end surface of the locking cup is provided with a groove, the lifting device is connected with a motor by input and output gears which are engaged with each other, the top of the convex plate is connected with a locking switch by a bolt, and the locking switch is connected with the motor by a connection line. The new gyro theodolite locking device has a simple structure, the motor and the locking switch are used for control of rising or descending of a gyroscope sensitive portion, and the new gyro theodolite locking device is simple in operation, safe and reliable.

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...

Problems solved by technology

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 locking and releasing stroke of the cam lock and release device is small, and the reliability is not high; the wedge lock and release device relies on friction during use, and the energy consumption is high; and the screw nut auxiliary lock and release Due to the sliding of the nut on the lead screw to realize the locking and lowering of the gyro sensitive part, the stability of the device is not high, and some of the above devices will shake violently and move too fast when the gyro sensitive part is lowered.
