This invention relates to devices for compacting railway ballast.

The purpose of the invention is to improve the quality of the seal baplast

On figoI podborka, front view; figure 2 - the connection elements of the kinematic pair of a rotary hinge by means of springs; figoZ - connecting rod with shank by torsion; FIG. 4 is the same side view; figure 5 is a diagram of the work of the pads; na - tamping with the axis of the rotary hinge, inclined to the shank; Fig, 7 is a diagram of the operation of the collar in Fig.6; on the location of podboek during the operation of the pod-pivochny unit.

The tamping machine pod contains a shank 1, a working blade 2 connected to the shank 1 by means of a rod 3 mounted rotatably around its axis 4, the latter being angled to the shank 1 (phi, b) connected to the rod 3 by an elastic element, which is a torsion bar 5 or consists of two springs 6 located on both sides of the longitudinal axis of the rod. The axis 4 is tilted during operation at an angle to the longitudinal axis of the path. The baffle has limiters 7.turn of the rod 3 relative to the shank I, At the same time, the shoulders of the working blade 2 are made of different sizes (and 3). The torsion bar 5 is an element that, with the eccentric total load on the blades 2, allows the latter to rotate. If the torsion bar 5 is made in the form of a plate (fig. 3 and 4), then during the rotation of the blades 2 from the forces of resistance C71I

due to the unequal stiffness of the torsion in the longitudinal and transverse direction of the shoulder blade 2, it tends to go under the sleeper and move closer to the rail at a distance from (FIG. 3, the movement is indicated by arrows) which improves the ballast compaction under the sleeper in the area of the rail near the shoulder b of the rail b the blades 2 are made with a large far from the rail shoulder cx of the blade 2 (figoZ). When the ballast of the blade is compressed, the blades 2 tend to turn to the rail with their working surface due to different

shoulder forces acting on the shoulders 15 of the blade 2, thereby the ballast is driven under the sleeper, the blades 2 are rotated in the final position by the angle 0 (figv2) o

Punching works as follows

After turning on the vibration of the collar and inserting it into the ballast of the blade 2; they approach each other, and they rotate relative to the shank 1 (shown in dotted line), making CL rotation) If the shoulders a and b of the blades 2 are the same, then a more uniform ballast compaction occurs. under shpar; oye; If shoulders a and b are not equal (figv 1 and 3), go ed blades 2 turn with their working surface to repress in the process of increasing the resistance of the ballast to compaction, Tae. in the process of drawing closer

is lowered due to the rotation around the inclined hinge 4 (fig. b), the other shoulder captures more ballast J from below and moves it under the sleeper and HDD (shown by a dotted line in the figure, 7). This achieves a uniform compaction of the ballast and a reduction in the number of working cycles when compacted. When the hinge axis is at a 10th angle, the longitudinal axis of the blade 2 tends to go along the line of least resistance and turn around the hinge, while the shoulder of the blade closer to the rail tends to rise and the far shoulder descend The working surface of the blade tends to turn rail and come closer to the station, which improves the ballasga under the sleeper at the intersection with the rail

When the limiting angle c3 of rotation of the blades 2 is reached, the stops 7 abut against the shank 1 (FIG. 2),

Upon completion of the compression of the spring 6 or torsion 5 return the blades 2 to the initial position relative to the shank "

With Prt and i, (J opposite blades 2 and in the process with the possibility of rotation around its 40 All deformation spring 6 and torsion 5,. At the same time, the ballast is pushed under the well in the rail zone, which improves its non-drying capacity. If you connect the worker, the rod 3 with the shank 1 by the torsion 5, then when the blades 2 come together in the process of sealing the ballast, the blades 2 tend not only to turn to the rail 3 but also come closer to it (the movement is indicated by arrows on the fig) because the torsion 5 is made in the form of a plate. If the axis of the rotary hinge is tilted at an angle p, to the vertical (to the tail 1), then when the blade 2 is compressed, to turn the work surface in the direction where olshe resistance, the shoulder blades, where the lower the resistance goes down and picks up from below the ballast, this shoulder blade resistance increases, and the shoulder is suspended 50 axis, characterized in that, in order to improve the quality of the ballast packing, the indicated axis of rotation is angled to the shank, which is connected to the rod by means of an elastic element, 2e A baffle according to I, characterized in that the shoulders of the working blade relative to the rod are made of different sizes, 3, A sheeting according to Claim 1, in which it is a case that the elastic element is a torsion 4c.
