Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a long defeated natural gas line stabilizes installation mechanism, including first pipeline 1, second pipeline 2 has been cup jointed to the one end of first pipeline 1, first pipeline 1 and second pipeline 2 all are provided with components of a whole that can function independently locking device 3, the tip at two pipelines is attached to the 3 cable of components of a whole that can function independently locking device, so that keep relative static with the pipeline, and be connected with between two sets of components of a whole that can function independently locking device 3 and draw near device 4, then draw near the adjustment by the distance of drawing near device 4 to two pipeline tip, this mode can wholly advance when enabling the pipeline butt joint, and can not cause great deviation, thereby cause the butt joint time overlength, this butt joint mode is also more stable.
