Usually, the fluid is pressurized by blowers, compressors, pumps and boilers, and then flows from the high-pressure part of the pipeline to the low-pressure part. The fluid can also be conveyed by its own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects and various industrial installations.

[0004] In the above scheme, although there are many benefits, there are also the following disadvantages: the directional casters of the moving mechanism are fitted with the pipe, so that the device can move along the pipe by itself, and the position of the directional casters can be adjusted by adjusting the telescopic adjustment rod, which is suitable for use with pipes of different diameters. Since there are multiple directional casters and multiple telescopic adjustment rods, personnel have to operate multiple telescopic adjustment rods separately to adjust the positions of multiple directional casters. This operation will slow down the progress of the work. In addition, the method of splicing multiple hand-held rods to achieve rust removal of high-altitude pipes is more troublesome and will also waste the time of the staff. Utility Model Content
