FREELY-MOVABLE ROLLER SUPPORT OF PIPELINE Russian patent published in 2017 - IPC F16L3/16 

FIELD: construction.

SUBSTANCE: while moving a pipeline relative to the crossbar, roller units are used, each of which consists of a cylindrical roller, axes attached to the roller butts and supported by closed-type rotation bearings on the support racks of the roller unit. The lower roller unit is attached to the crossbar, and the roller is installed perpendicular to the longitudinal pipeline axis. The support racks of the upper roller unit are attached to the lodgment. The upper roller is installed parallel to the longitudinal pipeline axis and rests on the roller of the lower roller unit. To each lateral limiting element located on the crossbar on both sides of the pipeline, one roller unit with the rotation axis of the unit rollers, parallel to the vertical axis of the pipeline cross-section, can be fixed. Longitudinal linear thrust elements are fixed to the lodgment at the level of the lateral rollers from its opposite sides. The rollers of the upper or the lower roller unit can be mounted on the rollers of paired supporting roller units arranged symmetrically and in parallel with the rollers of the upper or lower roller units adjacent thereto.

EFFECT: reducing horizontal loads on foundation structures.
