Description

The utility model relates to technical means that are used to clean the internal and external surfaces of pipelines from bitumen, solid contaminants, scale and rust that form on the surfaces of pipelines, and can be used in utilities, energy, and other sectors of the economy to update the throughput the ability of water and gas pipes. The device allows you to clean the pipe, which was in operation for its reuse.

A device for cleaning the inner surface of the pipe, which contains a mechanism for rotating the pipe around its axis, a hopper for abrasive cleaning material and a beam cleaning organ connected to the compressed air supply system, nozzles from which feed abrasive material into the hopper (UA patent No. 20615, IPC 6 B 08 B 9/04. 1998).

But such a device requires a compressed air system and additionally has a bunker with a hard shell. In addition, such a device is not suitable for cleaning the outer surface of the pipes.

A known device for cleaning the inner surface of pipes, having a rod made in the form of a rod with helical grooves on the front to discharge deposits that are removed from the pipe walls (see declaration patent UA No. 34538, IPC 6 V 08 V 9/04, 1998) .

But such a device is intended only for cleaning the inner surface of the pipes and only one small diameter.

A known device for cleaning the surfaces of a pipeline, in which the pipeline is rotated on roller bearings and on one side of the pipeline, a cleaning abrasive material is fed into its internal cavity and at the same time the external surface of the pipeline is cleaned using rotating metal brushes (see UA patent application No. 48734, IPC 6 V 08 V 9/04, 2002).

Such a device comprises a roller support, a pipe rotation mechanism

around its axis, a hopper for feeding abrasive material into the middle of the pipe and a tray for collecting it, additional external metal brushes with an independent electric drive for their rotation and mounted on the carriage with the possibility of longitudinal movement along the pipe. In this case, the roller bearing has the ability to deviate from the horizontal position, and the pipe rotation mechanism has the ability to smoothly control its rotation speed.

The disadvantages of this device include the fact that abrasive material is fed into the inner cavity of the pipe, which must then be returned again to another pipe, the supply and addition of water, solvents or emulsions requires their return, that is, the formation of a closed system.

The closest in essence and the number of significant differences is the device that is proposed in the indicated UA patent No. 48734, which has common essential features: the device has roller bearings, a pipe rotation mechanism, as well as external metal brushes with an independent electric drive.

In the specified device, as in the proposed one, the problem of expanding technical capabilities is solved by cleaning both the inner and outer surfaces of the pipe, but in different ways and different device designs. In addition, the proposed device eliminates the need for water and abrasive material.

A device for cleaning pipes has: a unit for external cleaning of pipes from bitumen, rust and other contaminants. This unit is a bed with two rows of electric rollers located on it.

On both sides of the bed there is a rail for moving the carriage with a cleaning device, which has the form of scoring rollers, cutters for rough cleaning and brushes to remove residual dirt; All this gives the pipe a marketable appearance.

In the device, the internal cleaning of the pipe from rust and other contaminants is carried out using mills, which are made of hard alloy. This node is a rod, at one end of which are located

cutters and brushes, and on the other - an electric drive. The rod is assembled from cardan joints (parts) and placed in a protected case, which looks like a pipe. The bar is mounted on the side of the electric drive to a mobile stand-alone carriage.

The operation of the device is controlled from the control panel, which is located on the carriage, which moves on wheels using a separate drive. On the control panel are all the bodies that perform individual actions related to cleaning the pipes. The remote control is located in a separate enclosed cabin with windows.

The principle of operation of the device is that the pipe is placed between two rows of rollers using the horizontal movement mechanism, the distance between the rollers is regulated depending on the diameter of the pipes, when the rollers are turned on, the pipe rotates around its longitudinal axis.

Significant differences of the proposed product is the new design of the mechanism of rotation of the pipe, made in the form of three pairs of rollers, which have a rubber surface and a mechanism for turning the rollers in a helical gear, which is carried out from a separate reversing engine. The rollers are made in the form of wheels having rubber tires that do not form a lot of noise.

Convenient location of controls in a separate insulated cabin, which moves on wheels along a rail track together with a mobile carriage, which has the form of a portal, allows you to protect the operator and meets ergonomic requirements.

The cleaning mechanism of the outer surface of the pipe has some distinctive features: on a separate frame, which is spring-loaded with two springs, there are two brushes made of pieces of cable; on the side of the brushes are two pairs of knives with an adjustable angle of inclination. The knives are made in the form of cutters made of hardened steel St65G. Knives cut large deposits of rust, debris and, thus, perform the main work, and the brushes clean the pipe completely. Brushes made of pieces of cable

which are joined together by rims and fixed to a movable frame, the frame has springs and is combined with a winch that raises and lowers the frame on which the separate drive is located. This movement of the frame with brushes and knives allows you to clean the pipe with a diameter of 210 to 1420 mm.

To clean the pipe in the middle, a movable rod is made, which is located in the pipe. The rod is assembled from separate parts and mounted on the electric drive side on a separate mobile carriage, and on the milling side - on the backup roller. At the end of the rod there is a round mill and a calibration ring and a brush that rotates on the rod, which moves along the longitudinal axis of the pipe.

This embodiment of the parts of the device allows you to simultaneously clean the outer and inner surfaces of the pipe for 10-15 minutes, which allows you to return the pipe to reuse.

The essence of the proposed solution is illustrated by drawings, where in Fig.1 shows a General view of the device, Fig.2 is a side view of the device, Fig.3 shows the end of the rod for internal cleaning of pipes, node A.

A device for cleaning the surfaces of pipes is located on the frame !, on which there is a rail 2, on which the portal 4 moves on wheels 3. On the portal 4 there is a cabin 5 with a control panel, a carriage 6 with cleaning devices: cutters 7 for rough cleaning and brushes 8 to remove residual contaminants. Brushes 8 are made of separate segments of the cable, which are combined by rims and fixed to the carriage 6 and rotate from a separate drive. The carriage 6 is located on the suspensions 9, which are suspended from the winch 10, the winch 10 moves the carriage 6, which allows you to clean pipes of different diameters.

To clean the pipes in the middle, a rod 11 is formed, formed from separate parts and fixed to a separate mobile electric drive 12, which is located on a movable wagon 13, which on wheels 14 moves along rails 15. At the ends of the rod 11, which is located in the pipe 16, circular cutters 17 and brush 18. At the ends of the cutters 17 is a calibration ring 19.

The rod 11 is connected to an electric drive located on a mobile wagon 13.

The operation of the device is as follows: the pipe is placed between two rows of rollers 20, the distance between which is regulated depending on the diameter of the pipes. The pipe 16 rotates at revolutions of the rollers 20. It is possible to move the pipe under the action of inertia to the left or right side, so it is possible to deflect the rollers from the control panel, that is, you need to rotate the movement of the pipe to the other side. The carriage 6 is moved to the edge of the pipe using an electric drive. Cutters 7 are brought to the pipe, which are located and fixed on the carriage 6. From the control panel, the pipe cleaning mode is selected depending on the diameter and its contamination.

Then include the movement of the carriage 6, which moves along the pipe from one edge to another. Simultaneously with external pipe cleaning, it is possible to carry out pipe cleaning in the middle of it. This includes the rotation of the cutters and brushes.

In addition to cleaning the pipe, trimming and chamfering at the ends of the pipe is possible using a separate device such as "Orbit", which can be included in the package.

The advantage of the proposed device is the absence, during operation, of the need for compressed air, water and abrasive material.

Using the proposed device design in comparison with known devices has significant advantages: the quality of cleaning pipes of various diameters and various contaminants is improved, the productivity of the device is improved due to the inclusion of idle pipes before processing, the ability to perform several pipe processing transitions - internal and external, as well as trimming and cutting chamfers on a pipe.
