Description

one

The invention relates to the maintenance of pipelines from the inside of its surface and can be used as a vehicle.

The closest to the invention technical solution known is a device for moving through a pipeline, comprising a housing with two groups of brushes, the first of which is mounted with the possibility of axial movement relative to the housing from the actuator. In such a device, axial movement of the brushes relative to the pipeline is provided by de-. balanced mechanism, as a result of which an axial alternating force arises, sweeping brushes and the apparatus as a whole 111

However, the use of the device is limited due to intermittent movement through the pipeline.

The purpose of the invention is to expand the scope of use by ensuring continuous movement through the pipeline.

This goal is achieved by the fact that in a device for moving through a pipeline, comprising a housing with two groups of brushes, the first of which is installed with a possibility.

axial movement relative to the housing from the drive; the second group of brushes is installed with possibility. axial movement, reverse in the direction of axial movement relative to the first group of brushes, and associated with an additional drive introduced into the device, wherein both groups of brushes can be connected

0 with drives through screw gear transmission.

The drawing schematically shows a device for moving through the pipeline.

A device for moving through conduit 1 comprises a housing 2 with two groups of brushes. Each brush of the first group is made in the form of a base 3 / on which resilient

0 elements 4, and each brush of the second group is named by it (it has a base 5 on which elastic elements 6 are fixed. The first group of brushes is mounted with the possibility of axial movement relative to the housing 2 from the actuator 7, and the second group of brushes is installed with the possibility of axial movement opposite to the direction of axial movement relative to the first group I py, and is associated with the drive 8. The first

and the second group of brushes are connected to the drives 7 and 8 through the screw gear transmission. It is possible to use one common drive and other types of gears. In the working position, the elastic elements 4 and 6 are pressed against the walls of the pipeline 1, forming at the contact points an angle of 5-1 between the elastic elements 4 and 6 and the normal to move the brushes in one direction and jam them when trying to move in the opposite direction. Case 2 at its opposite ends. having flanges respectively 9 and 10 for fastening the transported equipment. Drives 7 and 8 are coupled to electric motors, respectively 11 and 12, and are rigidly fixed to housing 2.

The device for moving through the pipeline operates as follows.

When electric motors 11 and 12 are switched on, the drives 7, respectively, tend to move the brushes of the first and second groups in the direction of the flanges respectively 9 and 10. At the same time, the elastic elements 4 of the brushes of the first group do not allow these brushes to move relative to pipeline 1 due to jamming, therefore the housing 2 will move from bottom to top. At the same time, the brushes of the second group will move downward relative to the housing 2, the speed of which relative to the pipeline 1 will be twice as high as the speed of the housing 2. At the end of the working stroke, the actuators 7 and B reverse, and the brushes of both groups begin synchronous movement in the opposite direction. Now, with respect to the pipeline 1, the brushes of the second will become fixed, since their elastic elements 6 are wedged on the pipeline 1. At the same time, the housing 2 continues its movement in the downward direction

upward, and the brushes of the first group move upwards both by moving the housing 2 and by operating the drive 7. At the end of the working stroke, the device will take up its initial position, and then the next similar cycle begins. The device is continuous. moves through pipeline 1.

Thus, the installation of the second group of brushes with the possibility of axial

movement, reverse in the direction of axial movement relative to the first group of brushes, and the presence of a connection of the second group of brushes with an additional drive introduced into the device provides continuous movement

5 through pipeline 1 of the described device, which leads to the expansion of the field of application of the latter.
