The invention relates to working bodies of tamping machines and can be used on other track machines where there are aggregates for ballast compaction.

The purpose of the invention is to improve the quality of the ballast compaction by providing directional movement of the ballast particles during its compaction.

FIG. 1 shows a tamping unit with tampers, the working surfaces of the blades of which have a concave shape in the form of a cone surface; in fig. 2 - working surface of the working blade;

the surface of a truncated cone; in fig. 3 - the same, in the form of an ellipsoid; in fig. 4 - the same, the center of the ellipsoid is offset from the symmetry axis of the outer contour; in fig. 5 - working surface of the blade as part of the surface of the sphere; in fig. 6 - option to install a working spat on the shank; FIG. 7 is the same, the concavity of the working blade is deeper; in fig. 8 - the same, the center of the concavity is shifted relative to the center of the contour of the working blade of the liner; in fig. 9 - the same, the blade has an asymmetrical contour; in fig. 10 - recesses in the form of ellipse surfaces are made on the working surface of the blade; in fig. 11 - the same, deepenings in the form of surfaces of the sphere; in fig. 12 - clarification of work podboek.

The tampers are part of a tamping unit comprising a frame 1 on which the hydraulic cylinder 2 is displaced in the vertical plane of the holder 3, which is housed in the rails 4. On the holder 3 by means of hinges 5, there are fixed tampers consisting of tailings 6 and workers blades 7, the Upper part of the shank 6 are connected by a hydraulic cylinder 8 of their filing. At the end of one of the pads, a vibrator 9 is installed. Between one of the shanks 6 and the holder 3, a centering element 10 is mounted, which prevents the pads from folding into the ballast. The working surface of the blades 7 is made concave to prevent leakage of ballast when it is compacted (Fig. 1). The working surface of the blades 7 can be made as part of the surface of a truncated cone (Fig. 2), as part of the surface of an ellipsoid (Fig. 3), as part of the surface of an ellipsoid, the center of which is offset relative to the symmetry axis of the external contour by an amount a ( Fig. 4).

According to FIG. 5, the working surface of the blade is a part of the surface of the sphere. The blade 7 can be mounted vertically on the shank 6 (FIG. 6-8), t, e, with a vertical arrangement of the major axis of the ellipsoid, while in FIG. 7, the concavity of the working blade 7 is made deeper, and in FIG. 8, the center of the concavity of the blade 7 is shifted relative to its contour center by an amount b.

The shapes of the blades 7 influence the direction of movement of the ballast. Therefore, the shape of FIG. 1 - and 2 allow the ballast to be shifted up or down, respectively, and to form the supporting column of the ballast under the sleeper. With a large amount of ballast in the sleeper door, the knockout of FIG. 1, this ballast is pushed down and under the tie. In the form of a collar in FIG. 2, the ballast tends to move upwards, and the zone can be compacted directly under the sleeper. The shapes of the working surface according to FIG. 3-8 allow the ballast to be held before tamping. Arrows indicate the possible movement of ballast particles.

The directional movement of the ballast particles is necessary to provide varying degrees of its compaction along the height under the sleeper or to shift the ballast to the side in order to increase the bearing capacity of the ballast and more compacted ballast where it is needed. The working surfaces of the blades 7 podboek can be made as part of the surface of a sphere or an ellipsoid (Fig. 3 and 12). When the working surfaces are made as part of the surface of a sphere (Fig. 5) or an ellipsoid (Fig. 3, 4, 6-12), the volume of the ballast located in the concave surface does not have the possibility of moving aside relative to the working surface of the blades 7. This volume mechanically by interconnecting the ballast particles with the volume of ballast between the braces, and these connections make it difficult for the ballast to spread to the sides when the ballast is compacted. The presence of recesses 11 on the working surface of the blade 7 of the pads increases the resistance to spreading of the ballast particles to the side of this working surface. The recesses 11, made in the form of the surface of a sphere, are more technological (Fig. 11) than the recesses 11. made in the form of ellipsoid surfaces (Fig. 10), which allow the ballast particles to have some freedom of movement in the horizontal direction and more compact filling ballast volume under the sleeper at the approach of the blades 7 podpoek. The displacement of the center of curvature of the working surface relative to the center of the contour of the working surfaces by a and 5

(Fig. 4 and 8) allows optimal distribution of ballast particles under the sleeper vertically, moving them up or down, or to the side, which increases the carrying capacity of the ballast. FIG. 12 shows a cross-section of the working blades 7 of the podpoyek on a horizontal plane. The arrows indicate the direction of the forces acting on the ballast particles during compaction. Such a shape of the working surfaces of the blades 7 of the pads does not allow the ballast particles to flow relative to the blades 7 of the pads and forces them to occupy a more compact position. The contour of the blades 7 of the baffles, made as part of the surface of the ellipsoid (Fig. 3, 4, 6, 7, 8, 10, 11), allows the pads to be more easily inserted into the ballast, less wear due to the uniform contact voltage pattern. the contour of the working blade 7 and the reduction of the efforts of the resistance of the ballast during the introduction of pads. The presence of an asymmetrical contour of the blade 7 (FIG. 9) makes it possible to reduce the frictional resistance along its contour when it moves to the side, for example when compacting ballast on switches.

Tamping unit with the specified execution of the pads works as follows,

The vibrator 9 is turned on, and the hydraulic cylinder 2 of the baffle, the vibrator, begins to sink into the ballast. After being submerged to the required depth, the feed hydraulic cylinder 8 is turned on, and the paddles 7 of the pads, the vibriro, approach each other. At the same time, the ballast particles tend to move along the working surface of the blades, as indicated by the arrows. The ballast particles are more compact, and the ballast is compacted. The working surfaces of the blades 7 of FIG. 1, 2, 4, 8, ballast particles are also distributed vertically, creating an optimal distribution of ballast compaction under the sleeper. The concave working surface of the blades 7 of the pads does not allow the ballast particles to flow from the compaction zone, which increases the quality

ballast compaction and its degree of compaction.

The presence of the curvilinear contour of the blade 7 reduces the effort of its penetration into the ballast, which increases

reliability podboek.
