Measuring combination tool for prefabrication installation of pipeline

Abstract

The invention provides a measuring combination tool for prefabrication installation of a pipeline. The measuring combination tool comprises a first straight rule and a second straight rule or a square master, an upper rotating body and a lower rotating body; the upper rotating body comprises an upper pressing cover, an upper rotating plate, two or more upper fixing bolts and an upper locating bolt; the lower rotating body comprises a lower pressing cover, a lower sliding plate, a lower fixing bolt and a lower locating bolt. According to the measuring combination tool, the combination angle of an elbow and the pipeline can be conveniently measured, efficiency and accuracy are high, and stability is good; the tool is easy and convenient to operate, and is obviously superior to an existing tool in an assembly measuring and re-measuring process of the pipeline, the accuracy is obviously improved, the corresponding rework amount is greatly reduced, and rework is almost eliminated; one person can operate the tool, saved time cost can counteract tool cost after the measuring combination tool is used for 10 days, and the performance cost ratio is high.

Description

technical field [0001] The invention relates to a measuring tool, in particular to a combined measuring tool for prefabricated installation of pipelines, which can measure the angle between an elbow and a pipeline, and the angle between a flange and a pipeline. Background technique [0002] In the prefabrication and installation of industrial pipelines, the workload of pipeline prefabrication accounts for more than 30% of the total construction volume, which takes up a lot of manpower, machinery and equipment and construction time, and the production efficiency is low and the labor intensity is high. Although the technology of modern industrial production continues to improve, the wide application of computer-controlled automatic and semi-automatic mechanical equipment has greatly improved production efficiency. However, at the construction site, the prefabrication and installation of pipelines is still dominated by manual operations at this stage, and it is difficult to rea...

AI Technical Summary

Problems solved by technology

Up to now, the most widely used pipeline measurement tools are right-angle bending ruler, spirit level, steel tape measure, spirit level, protractor, etc., using these tools to carry out prefabricated measurement of pipelines, the operator needs at least 2 plumbers during construction, and the construction efficiency Low, high labor intensity; and due to the limitations of the technical level of the construction personnel and the improper location of the measurement method during the measurement process, the measurement accuracy often has large errors, and the operation process is cumbersome, resulting in flange deflection and inaccurate elbow angles. , pipe skew and other quality problems, the working time is greatly reduced
