(54) DEVICE FOR FIXING AND PROCESSING OF INTERNAL PIPE SURFACES

one

The invention relates to equipment for processing cylindrical articles of various pipe diameters, in particular, to devices for cleaning the internal surface of pipelines.

A device is known for fastening pipes of various diameters and treating their inner surface, comprising a housing with channels for supplying a working medium to an elastic cuff fixed in a pipe seat formed in the housing, and a check valve mounted on the supply line of the working fluid into the cavity of the pipe being processed on the housing a series of pipe jacks and a manifold connected with them are connected, connected to the working fluid supply line, and the elastic cuffs are made in the form of sleeves, which are connected with the body between oboj camera 1.

The disadvantage of this device is the fragility of elastic elements, fixing tubes. Particularly deteriorate the conditions for the operation of elements with repeated switchings during the change of processing media. In addition, the quality of clamping of processed products depends on

pressure medium, which p-odaetsya in the sealing cuff.

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

This goal is achieved by the fact that in a device containing a collector with clamps mounted on it for fixing pipes and means for supplying working medium, each clamp has a conical base and levers pivotally mounted on the clamp body, each end of which interacts with a conical base by means of a roller, and at the other end of each of them clamping prisms are attached.

15 In FIG. 1 shows the device, top view; in fig. 2 shows section A-A in FIG. 1. The device consists of a collector 1 and several clamps 2 installed on it for fixing pipes of various diameters. The design of the clamps is the same. The clamp, in turn, consists of a conical rubberized nozzle 3 supported on a spring-loaded valve 4. The nozzle 3 has the ability to move vertically in the housing 5 of the clamp, spring loaded 6, The clamp body 5 is fixed on the hollow rod 7. The pedal 8 is also attached to it. . T he of 7 passed through the seal 9 installed in the conical base 10 of the clamp, the collector 1 and the seal 11 of the collector. Three levers 12 are fastened to the clamp housing 5 by means of hinges. The clamping prisms 13 are pivotally fixed to the upper ends of the clamps 13. The lower ends through the rollers 14 rest on the conical base 10 of the clamp. The device works as follows. To fix the pipe in one of the clamps, the pedal 8 is pressed, which draws down the pull 7 with the clamp body 5 fixed on it, the spring b is compressed. When the clamping body 5 is moved downward, the hinged levers 12 fixed on it, moving along the conical base 10, radially diverge to the sides (opening of the levers is provided by displacing their centers of gravity). The pipe to be machined is installed in a rubberized nozzle 3. When the pipe is installed, the nozzle 3 moves downwards in the clamp body 5, and the spring-loaded valve 4 opens the channel for the supply of the processing medium. After the pipe is installed, the pedal 8 is released; the spring 6 pushes up the clamp body 5, and the levers 12, moving their lower ends upwards along the conical base 10, converge in the upper part and clamp the prisms 13 fix the pipe being processed. The working medium is supplied to the fixed pipe through the collector 1 and the holes in the hollow section 7. In the same way, the installation and processing of the pipes in the other clamps takes place. The device for fastening 1 and simultaneously treating the inner surfaces of pipes of various diameters with clamps for fixing pipes containing three levers and clamping prisms hinged at their ends, makes it possible to increase the durability of the structure with the possibility of changing processing media. The economic effect is achieved by increasing the durability of the structure. An apparatus for fastening and treating internal surfaces of pipes, comprising a manifold with clamps mounted on it for fixing pipes and means for supplying a working medium, characterized in that, in order to increase the durability of the device, each clamp has a conical base and levers hinged on clamp body, one end of each of which interacts with a conical base by means of a roller, and at the other end of each of them clamped prisms are pivotally fastened.
