Pipeline butt joint equipment

When the pipeline butt joint equipment is used for pipeline butt joint, two pipelines penetrate into a clamping cavity jointly formed by an upper holding device and a lower holding device of each pipeline clamping device, then the clamping cavities are adjusted to be small, and then the pipelines are clamped in the clamping cavities; according to the pipeline clamping device, the upper clamping device and the corresponding lower clamping device can jointly clamp one pipeline, and the distance between the two pipeline clamping devices is adjustable, so that after the pipeline clamping devices clamp the pipelines, the two pipeline clamping devices get close to each other, and then the two pipelines can be in butt joint. The pipeline butt joint device is simple in structure, low in construction difficulty, high in efficiency, low in cost and high in construction safety performance, after butt joint is completed, the clamping cavity is enlarged, connection between the other end of the upper holding device and the
