Problems solved by technology

Therefore, the measurement and calculation of the expansion bend is particularly important, because once the measurement is inaccurate or the calculation is wrong, the construction period will be delayed and great economic losses will be caused. The tool for measuring the expansion bend is the flange measuring instrument, so the flange measuring instrument Accuracy is an important factor affecting the accuracy of expansion bend measurement

Abstract

The invention discloses a ratchet wheel type mechanical measuring instrument which comprises a base, a measuring assembly and a ratchet wheel mechanism, the base is used for fixing a flange end face, the measuring assembly comprises a measuring instrument disc face, a horizontal scale plate, a vertical scale plate and a rope tying column, the measuring instrument disc face is perpendicularly fixed to the base through a fastener, and the ratchet wheel mechanism is arranged on the measuring instrument disc face. Fasteners are symmetrically arranged at the ends of the horizontal center shaft and the vertical center shaft on one side of the measuring instrument disc face, the horizontal scale plate and the vertical scale plate are matched with the fasteners in a rotating mode, and the rope tying column is located on the vertical center shaft and fixed to the base. And the ratchet mechanism is arranged on the other side of the measuring instrument disc surface and is fixed with the base. According to the invention, the horizontal angle and the vertical angle between the two flange end faces can be measured, so that the angle of the expansion bend needing to be prefabricated can be determined; the device is small, light and convenient to carry; and the device can also be used for other situations that angles of two end faces need to be measured on water and under water.

Description

Technical field [0001] The present invention relates to the field of marine oil engineering, in particular, in particular, to a ratchet mechanical measuring instrument. Background technique [0002] In the sea oil development engineering, it is necessary to lay a submarine pipeline and expansion bend. The most critical process connecting the tube flange expansion bend is the measurement of the relative spatial position and azimuth between the tube flange. The seabed pipeline and the platform are difficult to express and have deviations and the design of the design. The expansive bend is characterized by the actual underwater measurement after the installation is completed, and the angle of expansion bend is calculated, then The calculated angle is compared to the expansive bend design, and if the error is within the permissible range, the preform of the expansion bend is performed. Therefore, the measurement and calculation of expansive bend is particularly important, because onc...
