[0004] Although the above-mentioned prior art solutions can achieve the relevant beneficial effects through the structure of the prior art, they still have the following defects:

[0005] The pipeline is supported by support wheels. Although the pipeline can be supported after the spacing between the two support wheels is adjusted, the pipeline cannot be fixed. The pipeline can still roll, slip and jump between the support wheels. Therefore, it is impossible to ensure that the two ends of the pipeline remain stably fitted during welding, and misalignment is prone to occur during welding.

[0006] Regarding the above-mentioned related technologies, the inventor believes that the pipeline is supported by support wheels. Although the pipeline can be supported after the distance between the two support wheels is adjusted, the pipeline cannot be fixed. The pipeline can still roll, slip and jump between the support wheels. In this way, it is impossible to ensure that the two ends of the pipeline remain stably fitted during welding, and misalignment is likely to occur during welding.

[0007] In view of this, we propose a pipeline butt welding support device. Utility Model Content
