Description

TECHNICAL FIELD

[0001] The utility model relates to strain gauge installation technical field, specifically, and relates to an auxiliary device. BACKGROUND

[0002] Strain gauge is a kind of sensor for measuring the strain of object surface, and it is widely used in material testing, structural health monitoring and various mechanical engineering fields.The working principle of strain gauge is that when the object is deformed by external force, strain gauge is deformed along with it, and the strain is reflected by the change of resistance.The measurement accuracy and reliability of strain gauge are crucial to ensure the accuracy of test results.

[0003] In air conditioning industry, the application of strain gauge is particularly important.The pipeline of air conditioning system will be subjected to various stresses during long-term operation, such as temperature change, pressure fluctuation, structure vibration, etc.The accumulation of these stresses may cause the pipeline to leak, thereby affecting the normal operation and safety of air conditioning system.Therefore, regular testing of the operating stress strain of air conditioning pipeline is one of the important measures to prevent and reduce faults.

[0004] However, air conditioning pipeline has the characteristics of complex structure and compact space, which brings many inconveniences to the installation of strain gauge.

[0005] The traditional strain gauge installation method mainly relies on manual sticking, which often has the problems of difficult positioning, poor installation quality, low work efficiency, low accuracy of test results and poor test reproducibility, etc.

[0006] 1.Inaccurate positioning: when manually sticking, it is difficult to ensure the accurate placement of strain gauge at the specified position due to the limitations of human eyes and operating environment, which may lead to deviation of test data.

[0007] 2.Unstable sticking quality: during manual operation, it is difficult to control the uniformity of pressure and time, and uneven pressure or too short sticking time may lead to poor contact between strain gauge and measured surface, thereby affecting the accuracy of test results.

[0008] 3.Low work efficiency: manual sticking takes a long time, especially in complex tests requiring a large number of strain gauges, manual sticking has low work efficiency.

[0009] 4.Human factor interference: the skills and experience of different operators vary greatly, leading to uneven sticking effect, making it difficult to realize standardized operation and resulting in poor reproducibility of test results.

[0010] 5.Space limitation: the structure of air conditioning pipeline is complex and the space is compact, making it difficult to manually stick, which increases the difficulty and uncertainty of testing. UTILITY MODEL CONTENT
