The invention relates to a device for the construction and repair of a railway track, in particular to devices for compacting ballast of a railway track.

The purpose of the invention is to increase efficiency by adjusting the amplitude of vibrations of the pads.

FIG. 1 shows a device for sealing ballast, a general view (in the initial position and); in fig. 2 - the same, with the bottom-up position of the podboek and the upper position of the carriage with the eccentric shaft (the amplitude of oscillation of the podboy is the smallest); figure 3 is the same, with the lower position of the carriage

(the amplitude of oscillation of the bollards is greatest).

The device for sealing ballast consists of upper and lower frames 1 and 2, connected by means of guides 3 to each other. The frames 1 and 2 are hinged by means of the suspension 4 and fixed to the base machine 5. The lower frame 2 has rollers 6 with flanges for moving

along the track 7. A tamping unit is movably mounted on the rail of us x 3, on the axes 8 of the frame 9 of which there are sub-sheets 10. The upper frame 1 is connected to the frame 9 by means of cylinders 11.

A carriage 12 is also movably mounted on the guides 3, on which the eccentric shaft 13 is placed. The carriage 12 is connected to the frame 9 by means of cylinders 14. The eccentric shaft 13 placed on the movable carriage 12 is pivotally connected to the pads 10 by means of levers 15.

The device using the suspension 4 from the transport position on the base machine 5 (not shown) is lowered into the working position before the rollers 6 come into contact with the rail track 7 (as shown in Fig. 1).

 An eccentric shaft 13 is then rotated, which, through the levers 15, transmits an oscillating movement to the pads 10 around the axes 8. podboek on the frame 9.

After that, the cylinders 11, frame 9, together with the carriage 12 connected to it, are lowered along the guides 3 downward, immersing the oscillating pads 10 into the ballast in the girth of the rasps. The lowering frame 9 stops in the lowest position (Fig. 2), while under 42

The strikers 10 compact the ballast in the interstitial space.

The oscillation amplitude of the pads 10 in this position of the device is the smallest, since the angle between the longitudinal axes of the pins 10 and the levers 15 is much greater than 90. As a result, the longitudinal oscillations of the levers 15 are not completely transmitted to the pads 10.

and in the form of their components, equal in magnitude to the projection of the reciprocating movement of the lever 15 onto the tangent to the turning circle of the collar 10, conducted through the point

fastening the lever 15 to the flange 10. Next, by the cylinders 14, the carriage 12 with the eccentric shaft 13 presses down to the frame 9, which causes the ballast to be crimped under the sleeper by the liner

10 (Fig. 3).

When the carriage 12 moves down to the frame 8, the angle between the longitudinal axes of the pins 10 and the levers 15 decreases from its maximum value

(as shown in FIG. 2) to a value of 90 °, achieved in the lowest position of the carriage 12 with respect to the frame 9 (as shown in FIG. 3). When the specified angle tends to

90 °, an increase in the projection of the reciprocating movement of the levers 15 onto the tangent to the pivot circle of the pads 10 occurs, which causes an increase in the amplitude of vibrations of the pads. At an angle of 90 °, the longitudinal oscillations of the levers 15 are projected onto the tangent to the circumference of the pads 10 completely in magnitude and cause the oscillations of the latter to be maximum in amplitude.

Then, the extraction of the pads 10 from the ballast occurs in the reverse order: the raising of the carriage. 12 cylinders 14, lifting the frame 9 cylinders 11.

After that, the device is moved by the base machine 5 to the next sleeper, and the entire working cycle repeats.
