(54) DEVICE FOR CLEANING THE INTERNAL SURFACE OF A PIPELINE

The invention relates to devices for cleaning the internal surfaces of pipelines for various purposes.

The closest to the proposed invention in its technical essence and the achieved result is a device for cleaning the internal surfaces of a pipeline, including an npoNffiiBHyro head with holes, a working agent supply system and a ripper, made in the form of an infinite flexible element with incisor-blades С 1 mounted on the torus.

The disadvantage of this device is the poor quality of cleaning, due to the fact that it is impossible to obtain circumferential forces of a periodic action on the cutting elements of the ripper and to ensure constant rotational and translational re-pegging of the ripper.

The purpose of the invention is to improve the quality of cleaning.

This goal is achieved by the fact that in the device for cleaning the inner surface of the pipeline, which contains a flushing head with holes, fixed on it by means of the ripper axes, is made as an endless flexible element mounted on a torus with incisor blades, an endless flexible ripper element is wound on the torus. geodetic line, and the wash head has rollers mounted on the axles of its attachment to the ripper torus, with coils of an infinite element located between the rollers and having unbalances for half axial movement of the device in the direction of sediment. In addition, incisors are mounted on the torus between turns

15 of the flexible element of the ripper, and their working surface in the plan overlaps the path of the ripper.

FIG. Figure 1 shows a device for cleaning the internal surface of a pipeline, a general view; in fig. 2 ripper with cutter holder; in fig. 3 is a view A of FIG. 2; Fig.4 ripper, longitudinal section.

Device content sleeve 1 dl

25 supplying the working agent to the pipeline 2, the guide rails 3, the washing head 4, the cutter holder in the form of a smooth torus and the ripper 6. The washing head is provided with openings 7, 30 with a tip 8, and the rods 9 are attached to them with rods 9 with tool holder. The ripper includes an endless flexible element 11 with blades 12 fixed on it and unbalances 13 and cutters 14.

The device works in the following way.

The working agent under pressure through the sleeve 1 enters the washing head 4 and through the holes 7 is sent to the blades 12 located on the inner side of the torus 5, and causes the ripper 6, made in the form of an infinite flexible element geodesically wound on the smooth torus -screw movement around the centerline of the torus between the rollers 10. The unbalances of 13 installed on each of the turns of the ripper create a disturbing force of directional action that turns the washing head together with the cutter holder around the center Flax axis of the torus. The resulting circumferential force is transmitted to the incisors 14, which destroy the deposits in the pipeline. The destroyed deposits are transported by the backs of the blades 13 in the direction opposite to the translational movement of the washing head 4 and removed from the pipeline 2 by the flow of the working agent.

The proposed design of the device, due to the presence of unbalances on each of the turns of a flexible infinite element, creating a disturbing force of directional action, increases the intensity of the cleaning process.

In contrast to the known, it is improved from 5 operating conditions, since the destruction of sediments is carried out not by the blades of a flexible infinite element, but by the incisors fixed

on the torus, which significantly reduces the rate of sediment destruction in the pipeline.

In addition, making the torus smooth and geodeticly winding, on it a flexible infinite element allows us to simplify the construction.

At the same time, the conditions for moving the device along the inclined pipelines are created due to the mechanical force of the rod and vibrational oscillations without using special devices.
