Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel structure engineering testing technology, specifically relating to a coupling agent spraying device for steel structure testing. Background Technology
[0002] Steel structure engineering primarily uses steel materials. To ensure the structural strength of steel structure buildings, ultrasonic flaw detectors are used to inspect the welds of these steel structure building materials after construction. This prevents issues such as incomplete welds and leaks that could affect the construction and safety of the steel structure. A weld inspection instrument is a portable ultrasonic weld defect detector that can quickly, conveniently, non-destructively, and accurately detect, locate, evaluate, and diagnose various internal defects in workpieces. When using an ultrasonic flaw detector for weld inspection, a coupling agent is typically applied to the area to be inspected. The coupling agent is applied by a spraying device driven by the connecting arm of the inspection carriage. Current methods involve a pump delivering the coupling agent to the spraying device, which then applies it. This process is difficult to control the amount applied, resulting in poor uniformity, wasted coupling agent, and poor coating quality, which negatively impacts the accuracy of subsequent ultrasonic testing.

Under the action of the compressed air, the coupling agent is sprayed onto the surface of the steel structure to be tested. The spraying effect of the compressed air ensures the uniformity of the coupling agent spraying, guarantees the accuracy of the test, reduces coupling agent waste, and lowers costs.
