Flange alignment tool and operation method

Abstract

The invention belongs to the technical field of auxiliary mounting, and particularly relates to a flange alignment tool and an operation method. The flange alignment tool comprises a base, positioning mechanisms, a connecting rod and an alignment mechanism, wherein one end of each positioning mechanism is connected with the base, and the other end of the corresponding positioning mechanism is suitable for being connected with a bolt hole of a first flange; the connecting rod is vertically connected with the base, and can be longitudinally adjusted relative to the base; one end of the alignment mechanism is arranged on the connecting rod, and the other end of the alignment mechanism can be abutted against a second flange; the alignment mechanism can be adjusted along the axial direction perpendicular to the second flange, relative to the connecting rod; and the alignment mechanism and the positioning mechanisms are in parallel arrangement. Through the adoption of the flange alignment tool, flanges can be rapidly aligned. The flange alignment tool has the advantages of being flexible in adjustment, and small in space of occupation.

Description

Technical field [0001] The invention belongs to the technical field of auxiliary installation, and particularly relates to a flange alignment tool and an operation method. Background technique [0002] Flange connection is a commonly used connection method between components and pipelines. During installation, after rough alignment of the flange, precise alignment is required to install the connecting bolts for fastening. Due to the heavy weight of the components and pipelines, it is very difficult to adjust the position during the precise alignment process, which easily leads to flange dislocation and difficult installation. In addition, after long-term operation of the equipment, the pipeline may be bent and deformed due to stress and heat. When the installation is resumed after disassembly and overhaul, the dislocation of the flange is more obvious. It often occurs that the flange cannot be accurately aligned, the bolts are difficult to insert, and tighten. The gasket is easi...

AI Technical Summary

Problems solved by technology

Due to the heavy weight of components and pipes, it is very difficult to adjust the position during the process of precise alignment, which will easily lead to flange misalignment and difficult installation

In addition, after the equipment has been in operation for a long time, the pipeline may be bent and deformed due to stress and heat. When the installation is resumed after disassembly and maintenance, the misalignment of the flanges will be more obvious. It often happens that the flanges cannot be aligned accurately, the bolts are difficult to insert, and the bolts are tightened. Gaskets are easily damaged when bolts are fastened

[0003] At present, for small-diameter pipes, flange alignment is generally done manually with traditional crowbars, which is time-consuming and labor-intensive, and is easy to damage components, sealing rings and gaskets, resulting in leakage

When aligning large pipelines, engineering machinery such as cranes, jacks, and gantry frames are generally used to assist in the alignment. However, this method is often limited by the site, and the alignment work is even more difficult when the installation space for large pipelines is small.
