DEVICE FOR REPAIRING CRACKS IN ASPHALT ROAD COATING

摘要

FIELD: transport.SUBSTANCE: invention relates to devices for repairing road surface cracks. On the frame there are transverse guide rails, on which there are installed controlled travelling trolleys: the first trolley accomodates a milling unit and a hose ending of an industrial vacuum cleaner, connected with a hopper for rubbish generated by the milling unit, which is fixed on the frame; the second trolley accomodates an electric industrial heat gun and filler batcher connected by a flexible pipeline with a filler hopper. On the frame there is a power plant with internal combustion engine or socket for connecting an external power supply, control unit for wheels, trolleys, milling unit, industrial vacuum cleaner, industrial heat gun and batcher, as well as a unit for monitoring direction and speed. Wheels on the device frame are equipped with an electric motion and turn drive.EFFECT: invention is aimed at simplification of design and mechanisms, reduction of fire hazard and improvement of operating conditions.2 cl, 2 dwg
