MACHINE FOR CLEANING OF PIPELINE EXTERNAL SURFACE

摘要

FIELD: repair of main pipelines. SUBSTANCE: cleaning elements of machine are secured on flexible coupling members positioned in pairs symmetrically from both end faces of machine and having opposite direction of rotation in pair. Drive shafts of pair of flexible coupling members are arranged symmetrically on different sides of machine vertical axis. Every flexible coupling member has fixing device which prevents its longitudinal motion. Machine is provided with balanced load in process of cleaning. EFFECT: enhanced process stability. 2 dwg
