[0029] S6: Place the cylindrical casing part at the lower end of the gyrotheodolite downward along the vertical center line just above the multi-directional adjustment support frame, so that the annular mounting plate is placed on the upper plane of the annular ring at the upper end of the jacking sleeve;

[0030] S7: Connect the battery cable and communication cable according to the cable markings, and ensure reliable connection;

[0039] S16: Turn the laser emission switch on the top of the theodolite to the right, and the external laser is in the point-to-point state. According to the installation height of the measured equipment, operate the lifting control button on the electrical control box to control the electric push rod to drive the gyro theodolite to rise or fall;

[0040] S17: Combine the horizontal adjustment knob to make the laser irradiate the reference plane mirror of the device under test and reflect it back to the laser plummet;

[0041] S18: Rotate the hand wheel clockwise until it stops, so that the lifting sleeve rises by L2, and the distance L2 is equal to L1; L1 is the center distance between the laser aligner and the observation eyepiece;

[0042] S19: At this time, turn the laser emission switch on the top of the theodolite to the left to change the laser from the external laser state to the eyepiece emission state, observe the crosshairs in the eyepiece and the red laser crosshairs reflected by the reference plane mirror of the device to be tested, and adjust the horizontal and vertical dial knobs of the theodolite to make them completely overlap;

[0043] S20: After the crosshairs of the theodolite reticle are aligned with the target, press the confirmation button on the control panel, and the gyrotheodolite will calculate the north azimuth of the target for this measurement and display it on the control panel screen;

[0044] S21: The result of comparing the north azimuth of the target azimuth mirror with the north azimuth of the midship line is the angle between the two.

[0045] As described above, the present invention provides a fast positioning gyrotheodolite auxiliary tooling and a method of use. The auxiliary tooling can adjust the height of the multi-directional adjustment support frame according to the installation height of the device to be tested, and the height can be adjusted by jogging the corresponding control button. The operation is convenient and the adjustment is stable, so as to accurately control the lifting height. At the same time, a laser plummet is selected to replace the plumb bob, and a positioning monitor is combined to reduce the low-level bending and viewing, avoid the plumb bob shaking positioning time and improve the alignment accuracy of the engraved lines; multiple groups of adjustment parts of the multi-directional adjustment support frame are used to facilitate the rapid positioning and adjustment of the gyrotheodolite in the horizontal and vertical directions; the jacking adjustment mechanism is used to quickly adjust the height of the gyrotheodolite, reducing the time for the gyrotheodolite to be adjusted and the horizontal adjustment time after the adjustment. The auxiliary tooling, combined with the corresponding method of use, can effectively exert the function of the gyrotheodolite to find the north and aim at the target, and improve the efficiency of equipment positioning detection.

10. A method for using the gyrotheodolite auxiliary tooling as claimed in claim 9, characterized in that: The following steps are also included: S16: Turn the laser emission switch on the top of the theodolite to the right, and the external laser is in the point-to-point state. According to the installation height of the measured equipment, operate the lifting control button on the electrical control box to control the electric push rod to drive the gyro theodolite to rise or fall; S17: Combine the horizontal adjustment knob to make the laser irradiate the reference plane mirror of the device under test and reflect it back to the laser plummet; S18: Rotate the hand wheel clockwise until it stops, so that the lifting sleeve rises by L2, and the distance L2 is equal to L1; L1 is the center distance between the laser aligner and the observation eyepiece; S19: At this time, turn the laser emission switch on the top of the theodolite to the left to change the laser from the external laser state to the eyepiece emission state, observe the crosshairs in the eyepiece and the red laser crosshairs reflected by the reference plane mirror of the device to be tested, and adjust the horizontal and vertical dial knobs of the theodolite to make them completely overlap; S20: After the crosshairs of the theodolite reticle are aligned with the target, press the confirmation button on the control panel, and the gyrotheodolite will calculate the north azimuth of the target for this measurement and display it on the control panel screen; S21: The result of comparing the north azimuth of the target azimuth mirror with the north azimuth of the midship line is the angle between the two.
