[0075] Next, adjust the rangefinder fixing frame 20 through the fourth connecting member 23, thereby adjusting the levelness of the first measuring component 1, until the first level 26 and the second level 27 on the laser rangefinder 19 show that they have reached level; after confirmation, turn on the switch of the magnetic suction member 8 to allow the tooling to be adsorbed on the cabinet 300.

[0076] Next, the position of the second marking component 4 is preliminarily determined according to the center line and the tape measure, and the laser rangefinder 19 is turned on. The laser rangefinder 19 emits a laser to irradiate the receiving part 29; the transmission component on the second marking component 4 is used to make the second measuring component 2 move along the second direction ( Figure 2a The laser is irradiated onto the first scale line 32 by moving the slider 35 in the adjustment hole 36 so that the laser is irradiated onto the intersection of the first scale line 32 and the second scale line 33, and the position of the slider 35 is fixed; after confirmation, the adjustment dial 12 is locked by the positioning bolt 15.

[0077] Next, the laser rangefinder 19 is used to measure and check whether the installation dimensions are correct. After confirming that they are correct, the flange 16 is rotated left and right. Figure 7 As shown, the marking head 18 marks a positioning line 400 on the tank 300 , and also marks a transverse inspection line 500 along the edge of the base 5 in the second marking assembly 4 close to the first marking assembly 3 .

[0078] Finally, remove the ship level gauge positioning tooling, connect and complete the line segments, mark them with sample punches, and carry out subsequent work.

[0079] It should be noted that if Figure 8a-8b As shown, when the tank 300 is in a supine or lying position, measurement, positioning and marking can also be performed according to the above method.
