step seven: and setting the corrected theodolite on the corrected tripod to perform aiming.
In the third step, the zero error of the tripod plane is less than 10%.
In the sixth step, the plane error between the reference platform and the tripod is less than 30%.
As the preferable technical scheme, in step three, utilize three adjustable frock to finely tune the tripod, adjustable frock includes foraminiferous bolt, nut, steel sheet and base, and the base is fixed on the boats and ships deck, and the steel sheet is fixed on the base, and steel sheet central authorities are equipped with a screw, are equipped with in nut and the screw with foraminiferous bolt assorted screw thread, foraminiferous bolt passes nut and screw in proper order, and foraminiferous bolt's top is equipped with the jack, and the supporting leg tip of tripod sets up in the jack.
As a preferable technical scheme, the base is a U-shaped magnet.
As the preferable technical scheme, the levelness of the tripod is adjusted by adjusting the heights of the bolts with holes of the three adjustable tools, and the nuts are screwed with the steel plates after the adjustment is in place.
Compared with the prior art, the invention has the beneficial effects that:
According to the setting method of the equipment for positioning and aiming the ship surface, disclosed by the invention, the tripod and the deck can be reliably fixed through the adjustable tool, and meanwhile, the tripod can be finely adjusted, so that the problem that a reference surface is quickly established on a floating ship to ensure the precision can be effectively solved. The phenomenon that the tripod platform and equipment above the tripod platform slightly move due to displacement of the toe of the bottom of the tripod caused by vibration, horizontal fluctuation and other factors generated by other construction operations on a smooth deck is avoided, and therefore measurement accuracy errors are reduced. The method greatly saves the adjustment time, reduces the labor intensity, has the characteristics of simple and convenient operation, low cost and reliable precision, and can be widely used in other scenes such as land, high-rise buildings and the like.
