Description

Technical Field

[0001] The present invention belongs to the technical field of pipeline detection equipment and methods, and particularly relates to endoscopic detection equipment and methods for pipeline quality detection. Background Art

[0002] A pipeline is a device connected by pipes, fittings, and valves for transporting gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas within the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of uses, primarily in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] Pipeline quality refers to the ability of the pipeline to meet design requirements and usage requirements during use, including its physical properties, chemical properties, durability and other aspects.

[0004] Whether the thickness of the inner wall of the pipeline meets the standard is also one of the important parameters of pipeline quality. For example, when measuring the thickness of aluminum, copper or steel pipes, if the pipeline contains a large amount of garbage or other particulate impurities when using an X-ray thickness gauge, it will greatly affect the accuracy of the pipeline thickness data detection. At the same time, if the pipeline is too long, it will be inconvenient to clean it, which is not conducive to personnel operation, reduces work efficiency, and is not conducive to improving the safety of the detection equipment.

The air cylinder (38) is started, and the servo motor (3) and the cover are driven to move toward the outside of the workbench (1), and the first screw shaft (6) and the second screw shaft (9) are respectively inserted into the inner and outer sides of the pipe, and at the same time, the tensioning wheel (42) is driven to move toward the center of the workbench (1) and the tension of the second conveyor belt (26) is adjusted; S1.2, the servo motor (3) is started, the first slider (10) and the second slider (11) on the first screw shaft (6) and the second screw shaft (9) move synchronously, and the pipeline thickness detection work is completed through the X-ray emitter (12) and the detector (13); S1.

3. After the servo motor (3) of step S1.2 is started, the fixed block (14) rotates synchronously, and drives the rotating blade (16) and the scraper (19) to rotate on the first slider (10), and the inside of the pipeline can be blown and cleaned during the rotation; S1.

4. Under the action of the air pump (22), the garbage inside the pipe is absorbed into the box body. Under the action of mechanical transmission, the driving motor (30) drives the cutting knife (32) to crush the garbage, and then the third slider (28) drives the pressing plate (29) to press the garbage.
