Method for realizing U-shaped width monitoring of chemical cargo ship by using total station

Abstract

The invention relates to a method for realizing U-shaped width monitoring of a chemical cargo ship by using a total station, and relates to the field of ship construction. According to the method fordetecting the lower opening width of a U-shaped total section by the total station, the half width of the U-shaped total section is detected by erecting the total station; detection data is compared with a theoretical value to obtain a full-width change reference value; follow-up measurement data is compared with the theoretical value to obtain a re-measured full-width change value; the re-measured full-width change value is compared with the full-width change reference value; and welding adjustment is performed when a standard value is exceeded. The precision detection of the lower opening half-width change of the U-shaped total section is realized in combination with three-dimensional analysis software by fully utilizing measurement equipment; the total station is simple and convenient to operate; the measurement precision is high; field point location collection can be carried out on the U-shaped half-width through the total station; and after the collected data is matched with theU-shaped half-width theoretical data, the change situation of the U-shaped half-width can be directly judged on site, so that the phenomenon that welding is not accurate is avoided, and meanwhile, thelabor intensity of constructors is reduced.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for monitoring the U-shaped width of a chemical tanker by using a total station. Background technique [0002] In ship construction, especially for chemical tankers, there are a large number of U-shaped general sections in the cargo tank. At present, most of the shipbuilding companies use hanging hammers to confirm the width change of similar U-shaped general sections. Since the U-shaped general sections are placed on The site has been subjected to the influence of natural weather and the temperature difference between morning and evening for a long time. Therefore, in this process, the wire hammer hanging on the section will be put on hold for a long time. , the on-site personnel cannot detect it, and the segment width is uncontrollable, so precise welding cannot be achieved. Contents of the invention [0003] In order to solve the problem that the half-width ch...
