The invention relates to artillery guns, intended for zastrasivanja piles into the ground.

Known piston-power, providing zastrasivanje piles of single artillery guns by placing a piston in the gun [1]. However, this solution does not allow the use of piston-zabojnik with simultaneous operation of tools, consisting of several trunks, for zastrasivanja piles.

The closest in technical essence and the achieved result to the proposed technical solution is the piston-power installation to dive into the ground building elements, providing zastrasivanje piles of multi-barrelled artillery guns with rigid connection of all parts of the piston [2]. However, this solution does not allow to eliminate the action of the torque forces on each of the multi-stemmed trunks building tools by neodinakovo pushing the pile efforts of each trunk.

The problem to which the invention is directed, is the creation of a design that allows you to eliminate the rotational action of the moment of forces resulting from the differential pressure of the powder gases in the channels trunks, trunks that make up a multi-stemmed construction artillery cannon

The task of resets the use of signs, specified in the claims, in common with the prototype, such as the piston-power, designed to zastrasivanja piles into the ground of the multi-barrelled guns, including pistons inserted into the channels of the shafts and distinctive essential features, such as the piston-power made of a composite comprising two piston diameter equal to the caliber barrels, with the lower parts, made in the form of hemispheres, freely resting on the base of the hemispherical platform, which freely rests with its tip on the head of the pile.

The above set of essential features allows to obtain the following technical result is the elimination of the torque multilateral construction tools when zastrasivanje in the soil piles at greater depth.

The invention is illustrated in the drawings, where Fig.1 shows the piston before shot of Fig.2 - piston at the moment of shot.

The prototype disadvantages are eliminated due to non-rigid connection of the component parts of the piston-zabojnik and application of the hemispheres in the lower parts of the piston and the hemispherical platform, through which are passed the efforts from the shafts on zastraivaemyh pile and freely slide along the surfaces of contact with each other. In the trunks placed a cylindrical piston diameters equal to the caliber barrels. The bottom h of the STI pistons are made in the form of hemispheres. Hemisphere lower parts of the piston abuts the base of the hemispherical platform, which with its tip rests in the center of the head zastraivaemogo piles. Pile rests on the ground surface. During the ignition of the charges in the trunks of the pistons begin to move, passing the efforts of the combustion gases on the pile, resulting in the pile starts to move in the soil. If the force resulting from combustion gases of the charge in one of the trunks, becomes greater than the force resulting from combustion of a charge in the other shaft, a hemispherical platform, on the basis of which rest against the pistons, is rotated in the direction of the greater force, creating a rotational moment of force relative to the hemispherical top of the platform. However, due to the hemispheres of the piston that slides on the base of the hemispherical platform, the pistons do not change their vertical position, eliminating this effect torque hemispherical platform on the trunks.

The mechanism of action of inventions

Artillery multilateral instrument consists of unconnected one with the other barrel 3 and the barrel 4, vertically to the ground surface 12. In the barrel 3 and the barrel 4 is placed a cylindrical piston 1 and the cylindrical piston 2. The diameter of the piston 1 is equal to the caliber of the barrel 3. The diameter of the piston 2 is equal to the caliber of the barrel 4. The bottom h is ü piston 1 made in the form of a hemisphere 5. The lower part of the piston 2 is made in the form of a hemisphere 6. Hemispheres 5 and 6 of the lower parts of the pistons 1 and 2 rest on the base 7 of the hemispherical platform 8, the diameter of which is larger than the distance between the shafts 3 and 4. Hemispherical platform 8 of its top 9 rests on the center of the 10 heads of the piles 11 (see Fig.1). Pile 11 rests on the ground surface 12. During the ignition charge 13 in the barrel 3 and the charge 14 in the barrel 4 of the piston 1 begins to move in the barrel 3 and the piston 2 begins to move in the barrel 4, passing the efforts of the combustion gases through a hemispherical platform 8 in the top 9 of the hemispherical platform 8 and the center of the 10 heads of the piles 11 on the pile 11. Pile 11 begins to move in the soil 12. If the force resulting from combustion gases of the charge 13, becomes greater than the force resulting from combustion gases of the charge 14, the hemispherical platform 8 is rotated down from the side of the shaft 3 in the direction of the location of the ground 12 and simultaneously hemispherical platform 8 is rotated upward from the shaft 4 in the direction opposite to the location of the ground 12, creating a rotational moment of force relative to the top 9 of the hemispherical platform 8. However, due to the hemispheres 5 and 6, a sliding base 7 hemispherical platform 8, the pistons 1 and 2 do not change their vertical position, eliminating this action is e torque hemispherical platform 8 on trunks 3 and 4 (see Fig.2).
