DEVICE FOR MECHANICAL CLEANING AND TREATMENT OF SURFACES Russian patent published in 2004 - IPC

FIELD: oil-and-gas complexes; mechanical engineering; cleaning flat and curvilinear surfaces; cleaning pipes of different diameters; grinding and polishing surfaces.

SUBSTANCE: mechanical cleaning is performed due to change of construction of device and use of other working members. Proposed device is provided with rotor which may rotated its axle at simultaneous motion along surface being cleaned; rotor is provided with load-bearing structure to which levers are articulated; working member and additional weight are connected to each lever. Used as load-bearing structure is axle of rotor located perpendicularly relative to surface being cleaned; located near end face of this axle are hinges for swinging the levers in planes parallel to rotor axle. Ends of levers are secured in hinges and working member is secured not rigidly on opposite end. Additional weight is secured on connecting rod articulated to lever in its center portion; axis of lever is perpendicular to axis of articulation owing to which weight may swing irrespective of lever in plane coinciding with plane of swinging of lever or parallel to it.

EFFECT: extended field of application; improved service characteristics.
