Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection equipment, in particular to an ultrasonic thickness gauge used for pipeline detection. Background Art

[0002] Pipes have important applications in many fields, and pipes of different thicknesses often have different prices. At present, when some unscrupulous vendors manufacture pipes, the thickness of the pipe ends is thicker than the thickness of the middle part of the pipe. Therefore, it is necessary to measure the thickness of the pipe at different positions. Ultrasonic thickness gauge is a common pipe thickness testing equipment.

[0003] At present, when using ultrasonic thickness gauge to test the thickness of pipeline wall, workers need to inspect the pipeline from different angles. During the long operation, it will cause a large load on people's wrists, resulting in wrist pain. Therefore, we propose an ultrasonic thickness gauge for pipeline inspection to solve the above-mentioned problems. Utility Model Content

[0009] By adopting the above technical scheme, the ultrasonic thickness gauge body is installed in the inner cavity of the installation frame, and multiple groups of telescopic components are screwed onto the inner wall of the second installation tube. Then, the abutment component is pressed toward one side of the installation frame and the ultrasonic thickness gauge for pipeline detection is placed in the inner wall of the pipeline. Under the elastic force of the telescopic component, the abutment component is automatically pushed to move outward and the abutment wheel is tightly fitted with the inner wall of the pipeline, thereby making the detection head on the ultrasonic thickness gauge body fit with the inner wall of the pipeline. Then, the installation frame is pushed to move horizontally on the inner wall of the pipeline to test different parts of the inner wall of the pipeline, which is convenient for use in pipelines with larger lengths and reduces the load on people's wrists.
