FIELD: treatment facilities. ^ SUBSTANCE: invention is related to the field of cleaning of external surface of pipelines, in particular to mechanisms for drives of cleaning machine rotor drives. Mechanism for drive comprises electric drive with reducer, which through transfer mechanism is connected to crankshaft-conrod mechanism, which is connected to carriage. Carriage is equipped with axis, on which working units are coaxially installed with the possibility of rotation, which are embraced with flexible elements and form rope-block systems. Each of specified systems is equipped with auxiliary guide blocks to vary direction of traction force from plane of working unit rotation into plane of rotor rotation. At the same time flexible elements are fixed with one end through damping elements on frame, and by other end - hingedly on rotor. ^ EFFECT: mechanism makes it possible to reduce dynamic loads at rotor of cleaning machine with simultaneous simplification of design of the latter and provision of high quality cleaning of manifold pipelines surface. ^ 1 dwg |
