DEVICE FOR IN-LINE ROBOTIC MECHANICAL CLEANING OF PIPELINE SURFACE Russian patent published in 2025 - IPC B08B9/53 B08B9/04 

FIELD: performing operations.

SUBSTANCE: invention relates to devices for mechanical cleaning of internal surfaces of pipes from contaminants formed during manufacture and operation of pipelines. Disclosed is a device for in-line robotic mechanical cleaning of the surface of pipelines, mounted on a transport module of a robot, having the possibility of aligning along the axis of the pipe and translating inside the pipeline along the axis of the pipe, including a rotary electric drive, a rotating disc with cleaning elements installed on the axis of the electric drive and a means of radial mobility of cleaning elements, wherein the axis of rotation of the electric drive and the rotating disc with cleaning elements installed on its axis is directed radially and perpendicular to the inner surface of the pipe being cleaned; cleaning elements are a combination of brushes made in the form of a shoe with an array of bristles fixed in it in the form of rods made of elastic material and rigid gear wheels, at that, on the rotating disc there is an even number of brushes, which are arranged in pairs diametrically and in pairs diametrically balanced relative to the axis of rotation of the disc, wherein the bristles are directed along the axis of rotation of the disc, and the gear wheels are installed on the rotating disc in an amount of one or more pairs and are arranged in pairs diametrically and in pairs are balanced relative to the axis of rotation of the disc, wherein the number of teeth and their width on the wheels can be different, and the axis of rotation of the gear wheels is directed radially to the axis of rotation of the disc; each brush is rigidly fixed on the swinging lever, and the axis of the cylindrical hinge of the swinging lever is perpendicular to the axis of rotation of the disc and the radius of the disc, wherein the brush pads are mounted on the free end of the lever so that the bristles are directed perpendicular to the axis of swinging of the lever, wherein the packing density and the length of the bristles can be variable in the brush body; each gear wheel is installed on the swinging lever, and the axis of the cylindrical hinge of the lever is perpendicular to the axis of rotation of the disc and the radius of the disc, wherein the axis of rotation of the wheel is installed on the free end of the lever and is directed perpendicular to the axis of swinging of the lever; each swinging lever is spring-loaded with the help of a torsion spring relative to the rotating disc and in the transport position has an angle of inclination towards the axis of rotation of the disc in the direction to the cleaned surface of the pipe, and on each lever there are stops limiting the angles of rotation of the lever; centre of gravity of each swinging arm together with the brush or with the gear wheel is located lower along the axis of rotation of the disc in the direction of the longitudinal axis of the pipe relative to the plane perpendicular to the axis of rotation of the disc and passing through the axes of the hinges of the levers, on each swinging lever there is a guide rod located in the radial plane of the disk, with one end fixed on the lever and directed by the free end at an angle to the axis of rotation of the disk downwards from the plane perpendicular to the axis of rotation of the disk and passing through the axis of the hinge of the lever; on each guide rod, an adjustment weight is installed with the possibility of moving along the rod and with the possibility of rigidly fixing the position of the weight on the guide rod; at that, on different pairs of diametrically installed levers, adjusting weights can be different; annular brush is fixed on the rotating disc at a radius smaller than the radius of the cleaning elements mounted on the swinging arms; rotary electric drive with rotary disk installed on its axis is installed on disk radial mobility means with cleaning elements, which is made in the form of a two-link manipulator with articulated drives, having self-braking properties and made on the basis of worm gearboxes, wherein articulated drive adjoining rotary disc is equipped with force-moment transducer while manipulator links allow varying length and locking.

EFFECT: increasing the efficiency, speed and quality of cleaning with one device.
