MILLING-SCRAPER CLEANER OF ICE ON CONTACT WIRE Russian patent published in 2025 - IPC B60L5/02 H02G7/16 

FIELD: devices for cleaning wires from snow or ice.

SUBSTANCE: disclosed is a milling-scraper ice cleaner (MSIC) on a contact wire for electrified railway transport, which includes a metal frame to which detachable horns 9 are attached. In the front part of the frame there is shield 1 for directing the counter air flow into the working zone of cleaning for removal of fragments of glaze ice destroyed by the milling and scraper units. Behind shield 1 there is a milling unit consisting of cutter shaft 4 and two support bearings 3. On cutter shaft 3 there are disk knives 5, which are separated from each other by means of spacer sleeves 12. Clamping and fixation of disc knives on cutter shaft 4 is carried out with nut 14. Behind the milling unit, a scraper unit is attached, which consists of holders 7, to the upper flat part of which, having a positive angle of inclination to the horizon, scraper flat knife 8 is attached with its upper point exceeding the upper point of the cutter disc knives 5. During operation of MSIC the scraper unit is always in the working position, and the milling unit is connected to operation when the thickness of the layer of glaze-icy deposits (GID) on the contact wire increases. MSIC device is independent; it does not require supply and connection of any energy sources to ensure its functioning.

EFFECT: milling-scraper ice cleaner provides high-quality cleaning and removal of GID of various types and thickness, including tubular fragments left after melting of ice on contact wire, without deterioration of cleaning quality.
