[0042] The surface material of the auxiliary wheel 25 is rubber.

[0043] The workflow of this invention embodiment is as follows:

[0044] Control the rotation of the auxiliary motor 12, which drives the wheel seat 24 to move along the track plate 13. The wheel seat 24 drives the wheel plate 26 and the auxiliary wheel 25 to move, so that the auxiliary wheel 25 moves to the appropriate position and the pipe is placed on the auxiliary wheel 25.

[0046] Example 3: This example is a further elaboration based on Example 1 or 2. The horizontal plate 14 is fixedly connected to the track rod 15, and the trapezoidal block 19 is nested within the track rod 15.

[0047] The workflow of this invention embodiment is as follows:

[0048] When the motor 16 rotates, the trapezoidal block 19 moves along the track rod 15.

[0052] This device uses adjustable support columns 32 to support natural gas pipelines of different sizes. The four support columns 32 are tangentially contacted with the natural gas pipeline and are symmetrically arranged in the vertical and horizontal directions, resulting in better support. By using screws 18, the support columns 32 can be inserted into different positions in the pipeline, facilitating focused support in the drilling area. An electric push rod 20 is used to adjust the height of the support columns 32, making it convenient to support natural gas pipelines of different sizes and easy to use.

[0053] This device uses a linear module to enable the electric drill 5 to move in the front-back and up-down directions, facilitating drilling of natural gas pipelines of different sizes. It also features a cutting fluid pipe 4 to cool the drilling process and prevent localized overheating in the drilling area from damaging the pipeline.
