FIELD: cleaning internal surfaces of pipe lines from resins, paraffins, etc.
SUBSTANCE: proposed device includes working member with drive, interconnected working members made in form of barrel-shaped mill secured on load-bearing housing where electric motor is mounted on rotary supports. Said electric motor is connected with load-bearing housing by means of gear train. Carriers of gear trains of two load-bearing housings are interconnected by means of swivel joint. Direction of spiral of barrel-shaped mill is opposite on each load-bearing housing; electric motor housings and truck with running rollers where rope and electric cable are secured are interconnected by means of swivel joints. Proposed device is used for cleaning the pipe line surfaces not only from resins and paraffins but from solid projections of metal; device may be used for cleaning the surfaces at maximum curvature and at availability of lateral connections.
EFFECT: enhanced efficiency.
