Description

(54) DEVICE FOR CLEANING THE PIPELINE

one

The invention relates to pipeline transportation and can be used in the oil and gas industry.

A device for cleaning a pipeline is known, comprising chambers for launching and receiving cleaning elements, each of which is provided with ends, a shutter, a lid, a tray and a trolley, a lifting mechanism for reloading the cleaning elements and a mechanism for feeding the cleaning elements into the pipeline 1.

A disadvantage of the known device is a complicated structure that does not provide reliable operation.

The aim of the invention is to simplify the design and increase the reliability of the device.

This goal is achieved in that the tray of each chamber is connected to the lid. In this case, the cover is installed on the trolley, and the feeder of cleaning elements into the pipeline is made in the form of a power cylinder mounted on the inside of the cover of the end closure chamber.

FIG. 1 shows the described device, a general view; in fig. 2 - the same.

view from above; in fig. 3 shows a section A. — A of FIG. 2; in fig. 4 - section BB of FIG. 3; in fig. 5 - section B - B of FIG. four.

The device consists of a camera 1 start and camera 2 reception. Each chamber is equipped with an end closure 3. 4 with a lid 5, 6, a tray 7, 8 moved inside the chamber by means of a trolley 9, 10 and a winch 11, 12 with blocks 13, 14. A mechanism is installed on the inside of the lid 5 performed in

the form of the ram 16. The cavity 17 of the cylinder communicates directly with the internal volume of the launch chamber, and the cavity 18 with a tube 19 with a three-way valve 20. The latter communicates the cavity 18 either with

by draining the tank 21 or with the pump 22 mounted on the cart 9. On each lid 5, 6 of the end closure 3, 4 there are brackets 23 on which one end of the tray 7, 8 rests. The other end of the tray 7, 8 rests on the rollers 24 The brackets 23 enter the grooves 25 of the chute 7, 8 and connect the latter with the lid 5, 6, which in turn rests by means of the ball joint 26 on the movable carriage 9, 10. The latter can move along the rails 27 along the axis of the chamber 1, 2 between them. A lifting mechanism 28 serves to overload the cleaning elements 15 from tray 7 to tray 8. The device operates as follows. In the event of launching the lid of the end closure 3, the tray 7 is connected out of the chamber 1 via a winch 11 and the tray 7 connected in series with the lid 5 and the carriage 9 is installed. By means of a lifting mechanism 28, a cleaning element 15 is installed on the tray. t into the starting chamber 1. Then close the end valve 3. The crane 20 is installed in a position in which the cavity 18 of the power cylinder 16 communicates with the drain into the tank 21. In the chamber 1 serves the working medium under pressure, which, falling into the cavity 17 of the power cylinder 16, moves the rod of the latter, and with it the cleaning element 15 to the pipeline — is 29. The cleaning element closes the cross section of the pipeline, and the working pressurized mixture carries the cleaning element into the pipeline. In the case of acceptance, the cleaning element 25 that has come to the chamber is removed from chamber 2 as follows. The chamber 2 is cut off from the pipeline, the pressure in it is relieved and, by means of the winch 12, the tray 8, the cover 6 and the carriage 10, connected in series with each other, are discharged from the chamber. By means of the lifting mechanism 28, the cleaning element is removed from the tray 8. The cart 10 with the lid 6 and the tray 8 is guided to the chamber 2 and the end closure 4 is closed. Camera 2 is ready to receive. The proposed device improves the reliability and performance of trunk pipelines. The amount of annual savings from the introduction of the device on the 1400 mm gas pipeline is approximately 60 thousand rubles, taking into account that the USSR State Planning Committee plans to manufacture 20 units of the proposed devices per year, the amount from their introduction will be 1.2 million. PyQ g rdd Invention Formula for cleaning the pipeline, containing chambers for launching and receiving cleaning elements, each of which is equipped with an end closure, a lid, a tray and a trolley, a lifting mechanism for reloading the cleaning elements, a mechanism for feeding the cleaning elements into A chimney, characterized in that, in order to simplify the design of the device and increase the reliability of its operation, the tray of each chamber is connected to the lid, while the lid is mounted on the trolley, and the mechanism for feeding the cleaning elements into the pipeline is designed as a power cylinder mounted on side of the cap of the shutter chamber start.
