FIELD: equipment for removal of waste insulation, corrosion etc, in particular, equipment for cleaning of pipelines by means of rotary machines and may be used in repair and construction of pipelines. ^ SUBSTANCE: apparatus has carriage movable along pipeline to be cleaned, drive mounted on pipeline, composite toothed wheel and cleaning members. Composite toothed wheel is positioned for rotation on carriage rollers. At least three supports for working tool holders are set on toothed wheel. Working tool holders are pivotally positioned on supports on single-arm levers. Free ends of levers are embraced with annular spring-loaded cable. Drive is kinematically connected with composite toothed wheel. Construction of apparatus allows it to be used for cleaning of pipelines or repair of pipeline portions in difficult-for-access places and parts not liable to mechanization. ^ EFFECT: simplified construction, low weight, simplified readjustment for adaptation to different kinds of cutting tools depending upon type of pipeline under cleaning process. ^ 6 cl, 9 dwg |
