AI Technical Summary

Technical Problem

In existing technologies, when welding flat-face flanges to pipes, it is necessary to manually measure and adjust the flange hole positions, resulting in low welding efficiency.

Method used

A quick-connection device was designed, comprising a rotating column, a turntable, support bars, flange positioning rods, and an adjustment mechanism. Through the cooperation of the rotating column and the turntable, the flange and the pipeline can be quickly aligned and positioned. The support bars provide support, and the adjustment mechanism adjusts the spacing of the flange positioning rods to accommodate flanges of different sizes.

Benefits of technology

It improves the efficiency and safety of flange and pipe welding, adapts to the usage requirements of flanges of different sizes, and simplifies the hole alignment process.

Abstract

The utility model provides a kind of quick connecting device of flat welding flange and pipeline, including base, rotating column is rotatably installed on the top of base, rotating column upper end is fixedly installed with rotating disc, the convex strip is protruded in the middle of rotating disc upper surface, two support strips are provided on convex strip, two flange positioning rods are detachably installed on two support strips, adjusting mechanism for moving two groups of support strips is installed on convex strip. Rotating column has the supporting effect to rotating disc, and rotating connection between rotating disc and base is formed, which is convenient to adjust the welding position by rotating flange and pipeline during welding. Two flange positioning rods can penetrate through the butt joint holes of two flanges, which is convenient to align the butt joint holes between two flanges. The adjusting mechanism adjusts the distance between two flange positioning rods according to the diameter of flange, which is convenient to use different sizes of flange. The detachable design of flange positioning rod can replace flange positioning rod according to the diameter of flange butt joint hole, which improves the practicability.
