Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning equipment technology, and in particular to a flexible passage auxiliary device for pipeline cleaning equipment in deformed sections. Background Technology

[0002] Pipeline transportation is a crucial method for transporting oil and natural gas. During long-term operation, oil and gas pipelines are susceptible to blockages due to external factors such as earthquakes, construction work, and weather conditions like rain and snow. In severe cases, this can lead to oil and gas leaks, causing economic losses and environmental pollution. Therefore, it is essential to regularly clean and unclog oil and gas pipelines using pipeline cleaning equipment.

[0003] According to the announcement number CN220195832U, a flexible cup pig is designed for use in pipelines. When there are no obstacles that would prevent the pig from passing through normally, the front and rear cups are in normal working condition. If the pig encounters a blockage due to the flexibility of the cups, the pressure difference between the two sides of the pig in the pipeline will increase. As the pressure difference increases, the front and rear cups will change their position through the linkage of the main shaft ball cage structure, the support leg ball cage structure, and the spring, thus avoiding the obstacle and passing through the blocked section of the pipeline smoothly.

[0004] Existing pigs achieve flexibility through a ball cage structure, but the maximum working angle of the ball cage structure is only 50 degrees, while tees and elbows typically require 90-degree adjustments. This means that the ball cage structure pig cannot meet the normal flexibility adjustment requirements at these locations, affecting the pig's passability and cleaning effect.

[0005] Therefore, there is an urgent need to provide a flexible auxiliary device for the pipeline deformation section pig to solve the above problems. Utility Model Content

[0014] Through the above technical solution, the first battery provides power to the motor, and the fixing bolts fix the first mounting plate and the frame flange.

[0015] The present invention is further configured such that: the adjustment mechanism includes a first electric telescopic rod fixed to one side of the inner bottom wall of the second tube frame, and one end of the piston rod of the first electric telescopic rod passes through and extends into the interior of the cylindrical insert.

[0016] Through the above technical solution, the first electric telescopic rod drives the piston rod to extend and retract, and the piston rod controls the straightness and adjustment state of the first tube frame and the second tube frame by the insertion of the cylindrical insert block.
