Description

The invention relates to the cleaning of: Pipes from the inside with devices moving along the pipe, and can be used in mechanical engineering and other areas of the national economy.

 A device for cleaning the internal surface of pipelines is known, comprising a housing with centering elements, a hollow shaft mounted in the housing and a hydraulic conductor, a clean grating with a hydraulic rotation of its own axis connected to the shaft so that it can rotate along with it and having the ability to radially move: the shaft axis, the channels for supplying the working agent to the hydraulic actuators and the pressure regulator for pressing the cleaning head. to the surface being cleaned

A disadvantage of the known device is the limited capacity, since the hinged structure of the mechanism for the radial movement of the cleaning heads cannot sustain significant loads when pressing the cleaning head to the pipe walls

The purpose of the invention is to increase the productivity of the device.

The goal is achieved by the fact that in a device comprising a housing | With centering elements, a hollow shaft with a hydraulic actuator installed in the housing, a cleaning head with a hydraulic actuator of rotation around its own axis, connected to the shaft for rotation and with the possibility of radial movement with respect to the shaft axis, channels for supplying the working agent to the hydraulic actuators and a pressure regulator for pressing the cleaning head to the surface to be cleaned, the shaft is provided with an end flange with a diameter groove, and the axis of the cleaning head is zmeschena in the groove of the flange.

1 shows the proposed device, a longitudinal section; FIG. 2 shows a section A-A in FIG. 1, FIG. 3; a section B-B in FIG. 2,

A device for cleaning the inner surface. The tube includes a housing 1 with supports 2, mounted in housing 1 on bearings 3 a hollow shaft 4 with hydraulic rotation in the form of an impeller 5, a cleaning head 6, having a turbine 7 as a hydraulic rotation and equipped with a replaceable cleaning element 8, A nozzle 9 communicates with an impeller 5, an nozzle 10 interacts with an impeller 7. The working fluid to the nozzles is fed along a hollow rod 1 I, to which the housing is connected by an adapter 12, the fluid supply line to the nozzles 9 consisting of tubes 13 and 14 and the collector 15 is equipped a fluid flow regulator (not shown); Shaft 4 is secured against longitudinal movement by a nut 6 and lock nut 17 and has an end flange 18. The guide 19 mounted on the flange 18 forms a double-sided diametrical groove in which it can be radially moved. placed the slider 20, carrying the axis of the cleaning head 6. On the flange 18 is placed a regulator of the force pressing the cleaning head b to the surface being cleaned, consisting of a screw 21 with a nut 22, which by means of the spring 23 interacts with the slider 20, centering the treated pipe and the cleaning device conductor sleeve 24,

The device works as follows.

Along the conductor sleeve 24, the overhang of the supports 2 is adjusted. By moving the nut 22, the force of the pressing head 6 to the inner surface of the pipe is set. A replaceable cleaning element 8 is installed, which, depending on the properties of the deposits, can be made either in the form of a brush, or in the form of scrapers or an abrasive wheel. The conductor sleeve 24 is connected to the pipe to be cleaned, the device is equipped with translational movement, and working fluid is supplied through the rod 11. Part of the working fluid through the cavity of the adapter 12 and the shaft 4 is supplied to the nozzles 10 and from there to the blades of the impeller 7. At the same time, the cleaning head receives rotation around its own axis. Another part of the working fluid through the flow regulator, the tubes 13 and 14 and the collector 15, descends to the nozzles and from there onto the blades of the impeller 5. At the same time, the shaft 4 rotates, on the flange 18 of which the posture 20 with the axis of rotation of the head 6 is placed. The cleaning head 6 communicates a planetary motion relative to the shaft.

The proposed design can provide significant efforts to press the cleaning element to the surface being cleaned, which allows to increase

cleaning performance. In addition to the diameter that expands em

In addition, the proposed design can be technologically possible to be used for cleaning small pipes.
