О 111 The invention relates to devices for cleaning hollow articles and can be used in mechanical engineering. The purpose of the invention is to increase the efficiency and quality of cleaning due to the uniform deformation of the pipeline along the length. FIG. 1 shows the device, a general view; in fig. 2 and 3 is a sectional view in FIG. 1 (showing a drum with three or four rollers respectively); in fig. 4 shows a kinematic diagram of the device. The device contains a base 1 with a pumping system of washing liquid through a pipeline with inlet 2 and outlet 3 with pipelines, flushing the eMiOT pipeline 4, attaching to the closed tape 5 (Fig. 2 and 3), wrapping the drum 6. The drum 6 is installed on the base is 1I with the possibility of reciprocating rotational motion, and its surface is made in the form of a prism, the edges of which are formed by rollers 7 with the possibility of axial rotation. At least one roller 8 is made driven, kinematically coupled to the driving shaft 9, for example, through a block of 10 gears and through a variator 11. With the neutral position of the variator, there is no rotational movement of the tape relative to the axis of the drum. The device has a rotation drive 12 and a mechanism 13 for tensioning the ends of the pipeline. The hollow shaft 14 kinematically connects the variator and the roller 8. The device operates as follows. The pipeline is pumped washing liquid. Include the actuator 12 and rotate the drum in the neutral position of the variator. The rotation from the actuator 12 is transmitted through the shaft 9, simultaneously to the drum 6 and the variator. From the variator, the rotation is transmitted through the hollow shaft 14 through the B.1 10 block of block 10 to the roller 8, which causes the closed tape 5 to rotate relative to the drum. The gear ratio of the roller 8 and drum 6 (with the neutral position of the variator) is picked up by a gear block such that the rotational motion is closed the tape and the pipeline ONNGMTR placed on it. T. But the drum axis is missing, i.e. the linear speeds V (the speed of rotation of the material point b located on the roller at the maximum distance from the axis of rotation of the drum with no rotation of the roller relative to its own axis) and Vp (linear speed of rotation of the generator roller) are equal. Due to the change in gear ratio, the variator 11 is achieved by turning the tape with the pipeline about the axis of the drum and winding up one or the other end of the pipeline on the drum. At the same time, the rotational speed (rotation) of the pipeline, provided by the variator, is significantly less than the rotational speed of the drum. Moving the deformation zone along the length of the pipeline (around the circumference) provides better separation of contaminants from the walls of the pipeline. In the case of cleaning the corrugated pipelines, the corrugations are successively compressed and eject a portion of the liquid together with the contaminants into the flow. Each corrugation works like a micropump. It is better that the direction of movement of the flow of washing liquid coincides with the direction of rotation of the drum. In this case, the particles, washed out of the corrugations, do not precipitate back, i.e. no secondary sedimentation effect. Improving the efficiency and quality of cleaning is created without significantly complicating the design of the device. The device has smaller ga-. barite height, which is especially important when washing long pipelines, since the length of the hanging ends in this case may be minimal. The device has wide technological capabilities and is easy to operate, since there is practically no labor required when changing the design for changeover to clean pipelines of various sizes, diameters and lengths. The economic effect from the introduction of the device is due to an increase in the quality and efficiency of cleaning, the elimination of product returns due to poor-quality cleaning of cavities, as well as by increasing the reliability of products.
