Multifunctional ruler for pipeline construction

Abstract

The invention provides a multifunctional ruler for pipeline construction. The multifunctional ruler integrates the functions of a vernier caliper, a square ruler and a level ruler, can be used to detect the verticality between a flange and a pipeline, is easy to carry, improves the work efficiency, and guarantees the quality of construction. The multifunctional ruler comprises a vernier caliper section and a level ruler section, which are disposed in the same plane and are hinged to each other by a connecting ruler section. Hinge limiting parts are respectively arranged between the connecting ruler section and the vernier caliper section and between the connecting ruler section and the level ruler section, so that the connecting ruler section, the vernier caliper section and the level ruler section can rotate to the same line. The connecting ruler section and the vernier caliper section as well as the connecting ruler section and the level ruler section can be limited by right-angle positioning devices to form right angles respectively, so that a space for accommodating a flange or a connecting bend can be formed between the connecting ruler section and the vernier caliper section as well as between the connecting ruler section and the level ruler section.

Description

technical field [0001] The invention relates to the technical field of measurement and auxiliary tools for construction, in particular to a multifunctional ruler for pipeline construction. Background technique [0002] In the construction process of pipelines, flanges are usually used to connect pipelines. When installing flanges, flanges and pipelines are required to ensure a certain degree of verticality, flanges are parallel to each other, and pipelines have a certain level. A lot of data needs to be measured for this. A large number of measuring tools are needed on the construction site. Until now, the most widely used tools for measuring pipelines on the construction site include squares, levels, vernier calipers, etc., to measure the verticality between flanges and pipelines, and the horizontality between pipelines. Measurement, measurement of pipe and flange inner diameter. [0003] The use of existing measurement tools is often time-consuming and laborious. During ...

AI Technical Summary

Problems solved by technology

[0003] The use of existing measurement tools is often time-consuming and laborious. During the measurement process, due to the limitations of factors such as the technical level of the construction personnel and the improper location of the measurement method, the process is cumbersome, and the measurement accuracy often has large errors, flange deflection, and elbows. For quality problems such as inaccurate angles and skewed pipes, there are also rulers specially used for correcting the verticality of flanges and pipelines, such as the rulers mentioned in patent documents such as publication numbers CN203083508U and CN203401252U. However, in actual construction, in addition to such special rulers, Construction personnel still need to carry measuring tools such as spirit levels and vernier calipers to measure the levelness between pipes and the inner diameter of pipes and flanges. Construction personnel with a large number of measuring tools are inconvenient to carry, and they need to find corresponding measurements when measuring ruler, resulting in low construction efficiency and greatly reduced working time
