Bi-directional thermal displacement pipeline support

The utility model belongs to the technical field of high-temperature pipeline supporting pipeline supports, and particularly relates to a bi-directional thermal displacement pipeline support. The bi-directional thermal displacement pipeline support is characterized by comprising an upper support base and a lower support base, a convex spherical surface is arranged at the top of the lower support base, a concave spherical surface is arranged at the bottom of the upper support base and matched with the convex spherical surface, and an upper rolling plate, a middle rolling plate and a bottom plate are sequentially arranged at the bottom of the lower support base from top to bottom. Inclined iron is arranged between the upper rolling plate and the lower support base, and rolling body sets are arranged between the upper rolling plate and the middle rolling plate as well as between the middle rolling plate and the bottom plate. The bi-directional thermal displacement pipeline support is simple and reasonable in structure, convenient to manufacture and install and suitable for high-temperature pipelines of which the pipeline supports are large in load and the displacement is large in the two horizontal directions. The friction coefficient between the pipeline supports and supporting parts is decreased, and thrust exerted on a supporting beam by the pipeline supports is reduced.
