Support and hanger quantifying, mounting, detecting and regulating tool and method using same to perform support and hanger load measurement

Abstract

The invention relates to a support and hanger quantifying, mounting, detecting and regulating tool and a method using same to perform support and hanger load measurement. The regulating tool comprisesa first supporting assembly which is arranged on a hanger rod and is positioned below a turn-buckle, and a second supporting assembly which is positioned above the turn-buckle, wherein a force measuring assembly is arranged between the first supporting assembly and the second supporting assembly; the force measuring assembly at least comprises a force transmission rod which is arranged between the first supporting assembly and the second supporting assembly, and extends parallel to the hanger rod, a strain sensor which is adhered on the force transmission rod, a loading and unloading device for loading and unloading the force transmission rod, and a data processing device for acquiring strain data of the strain sensor and processing the strain data into force data. The tool can quickly and accurately quantify bracket load during mounting, detecting and regulating, and provides data support for standardized management of bracket mounting, detecting and whole-lifetime regulating.

Description

technical field [0001] The invention relates to a tool for quantitative installation, detection and adjustment of a support and hanger and a method for measuring the load of the support and hanger using the same. Background technique [0002] Pipe supports and hangers can generally be divided into variable force spring supports and hangers (similar to ordinary springs, the more compressed, the greater the load), constant force spring supports and hangers (as the spring compresses or rebounds, constant force spring supports and hangers provide The load remains unchanged), various constraints (limiting displacement in all directions, such as rigid tie rods, etc.). Variable force springs and constant force springs are collectively referred to as elastic hangers. The main functions are to carry the weight of the pipeline, control the thermal displacement of the pipeline and limit the vibration of the pipeline. whether it is safe to operate, see attached figure 1 to attach im...

AI Technical Summary

Problems solved by technology

For the variable force spring hanger, the spring load is estimated according to the spring scale, and the error is extremely large; for the constant force spring hanger, because there is only a displacement pointer and no load indicator, the actual load cannot be known; for rigid components such as constraints in all directions , there is no load indication, the actual load cannot be known, and it can only be judged by experience, lacking quantitative data support;

[0005] (2) The stress-strain measurement technology currently used in the mainstream needs to attach strain gauges. The test process requires complicated auxiliary loading and unloading work. Rapidly disassembled, accurate and reliable support and hanger load testing equipment;

[0006] (3) The installation, detection and adjustment of the support and hanger requires a lot of coordination work, such as fixing the pipeline, locking the front and rear support and hanger, unlocking and unloading the main body of the support and hanger, etc., which are often time-consuming and laborious, the project is huge and the efficiency is relatively low;

[0007] (4) Certain auxiliary measures are required to fix or adjust the support and hanger components (such as threaded rods, connecting buckles, etc.) during the installation, inspection and adjustment of the support and hanger. It is not easy to check, and if it accumulates for a long time, there will be certain safety hazards (some supports and hangers have broken due to thread damage);

[0008] (5) At present, the standardized management of supports and hangers has included the pre-database collation and preventive maintenance of supports and hangers of in-service units. maintain
