Description

The utility model relates generally to the processing of metals by pressure and can be used in particular for straightening a deformed section, for example, an existing gas pipeline of small diameter 15-32 mm in the field, as it provides an opportunity to solve the problem of repairing the gas pipeline in the field without involving expensive equipment, using the claimed technical solution.

From the prior art examined by the applicant, a screw press for straightening pipes is known, including: the correct device, linings, support beams (see Nikolaev E.Y. Handbook for Special Works Technological pipelines of industrial enterprises Part 2 1964 p. 37-38 Fig. 4 (see Fig. 1 general view and description of a screw press).

A disadvantage of the known correct device is the lack of mobility, high weight, high production costs and the inability to use a screw press on an existing gas pipeline due to the above.

From the prior art examined by the applicant, there is also known a pipe straightening device comprising supports, a beam mounted on a rod, a stamp in the form of a bearing, the inner diameter of which is capable of providing a free placement of pipes in it, a load meter (copyright certificate No. SU 345997, B21D 3 / 10, published on 08/03/1972).

A disadvantage of the known device is also the lack of mobility, high weight, high production cost, volatility and the inability to use the device on an existing gas pipeline due to the above.

From the prior art investigated by the applicant, a device for straightening cylindrical products is also known, comprising a power hydraulic cylinder with a two-sided rod and a mechanism for restricting the action of the hammer, made in the form of an adjustable stop mounted with the possibility of movement. One end of the hydraulic cylinder rod is rigidly connected to the striker, and a stop element is placed at its other end, while the latter is installed with the possibility of interaction with an adjustable stop (patent No. RU 2107569, B21D 3/10, published on 03/27/1998).

A disadvantage of the known device is the lack of mobility, the heavy weight, the high cost of repair, the volatility and the inability to use the device on an existing gas pipeline due to the above.

From the prior art revealed a screw press, selected by the applicant as a prototype that matches the claimed technical solution on the basis of a set of matching essential features and the achieved technical result. The essence is a screw press, which is attached to the table and driven by rotating the flywheel, the press consists of a table, which is bolted, two prisms for installing a curved pipe, rod, flywheel, body and screw with a tip (see http: // tepka .rU / Praktikum_po_slesarnomu_delu / 5.6.html, http://www.ngpedia.ru/id24239p2.html and Fig. 2).

Thus, to work effectively with the screw press described above, it is required that the prismatic tip on the press rod be at the site of greatest curvature. At the same time, in order to avoid dents between the tip and the roller, gaskets are placed. Next, the flywheel is smoothly rotated and the screw tip is brought to the bend point. Then a screw is pressed on the corrected shaft until it straightens. Excessive dressing forces can cause reverse bending of the shaft or pipe, which will complicate further dressing.

A disadvantage of the known device is the lack of mobility, heavy weight, high production costs and the inability to use a screw press on an existing gas pipeline due to the above.

The claimed technical solution is illustrated by the drawings:

FIG. 1 - Portable device for straightening cylindrical products (analog);

FIG. 2 - Portable device for straightening cylindrical products (analog);

FIG. 3 - Portable device for straightening a deformed section of an existing gas pipeline.

The purpose of the claimed technical solution is to create a simple and mobile design that provides the ability to effectively repair deformed pipes in the field.

The task as a whole is solved due to the fact that the portable device for straightening the deformed section of the existing gas pipeline, comprising a housing in which a power element and means for accommodating the rectified pipe are installed, characterized in that the said housing is made with a U-shaped cross-section, while its upper part in the center of the upper shelf is rigidly mounted power element in the form of a rhombic jack with a screw-nut and a handle as its drive, and in its lower part at the ends of the lower shelf is installed means for accommodating the rectified pipe, made in the form of prisms, moreover, a cutout is made in the center of the lower flange for bending the deformed section of the pipe, and at equal distances from the center of the lower flange, guides are installed opposite the mentioned prisms to prevent the rectified pipe from jumping off.

A portable device for straightening a deformed section of the existing gas pipeline consists of a channel section (1), in the upper part in the center of the channel shelf a rhombic jack (4) is fixedly mounted which is fixed with bolts and nuts (5), and guides are installed in the lower part at the ends of the channel shelves ( 2) channel flanges rigidly fixed at equal distances from the center to prevent the rectified pipe from jumping off the portable device; prisms (3) are also rigidly fixed at the ends of the channel flanges at the bottom fastened on the channel for installing pipes with a diameter of 15-35 mm, a technological cutout (6) is made in the lower part in the center of the channel flange, comprising 1/3 of the length of the flange, designed to bend the pipe to overcome the elastic force (see Fig. 3).

A portable device for straightening a deformed section of an existing gas pipeline works as follows.

The portable device for straightening the deformed section of the existing gas pipeline is installed on the deformed section of the pipe, with a maximum bending angle directed to the thrust pad of the jack, then preliminary fixing and orientation of the pipe is performed to prevent the pipe from jumping off the device and for subsequent straightening of the bend, then the jack is driven by the rotation of the handle, the effect on the pipe is terminated provided that the pipe is completely straightened.
