Description

The invention relates to devices for repairing a railway track, in particular to aggregates of crushed stone cleaning machines, intended for planning and compaction of ballast of a railway track, namely, for compaction of the lower layer of ballast during layer-by-layer compaction.

A device for planning cleaned ballast, indicated in the rubble-cleaning machine, consisting of two endless chains installed in the drive housings located on both sides of the longitudinal axis of the machine, the chassis of which are mounted on the frame with the possibility of rotation around the vertical axis and in the working position are rigidly interconnected by means of pads, as well as a device for sealing the planned ballast, consisting of a beam located across the path on which the vibrodrive is mounted, mounted th on the frame of the chains, and the frame is provided with a drive to reinstall the height / SU, certificate of authorship №1122233, E 01 B 27/02, publ. 1984 /.

The disadvantages of the known device are:

- the complexity of the design due to the large number of working elements;

- increased complexity of installing the device in the working and transport position, caused by the fastening of chains under the rail-sleeper grid of the railway track;

- the placement of the elements of the drive endless chains and vibrodrive under the rail sleeper requires an increase in the height of the rail and sleeper or an increase in the depth of cut of the ballast, which reduces the efficiency of the gravel cleaning machine.

A device for planning and compaction of ballast of a rubble-cleaning machine, adopted as a prototype, containing two bearings located on both sides of the longitudinal axis of the machine with the ability to reset the height of the actuators, a device for planning ballast, including two buildings mounted on supports with the possibility rotation around vertical axes and interconnected in the working position, as well as a device for sealing ballast with a vibrator, mounted on these supports, housing The equipment for planning ballast in the working position is plow-shaped and interconnected by a roller docking unit, the front walls of the housings serving as a ballast planning shield, and the device for sealing the ballast consists of two vibro-units installed inside the housings using spring supports and articulated rods / RU, Utility Model Certificate No. 27830, E 01 B 27/02, publ. 2003 /. The disadvantages of the known device are:

- the placement of vibration blocks of ballast compaction in buildings increases their height and in the working position under the rail-sleeper grid of the railway track, an increase in the height of the rail-sleeper grid or an increase in the depth of cut of the ballast is required, which reduces the efficiency of the rubble-cleaning machine;

- the presence of a joint between the buildings in the working position of the device reduces the rigidity of the supporting structure in the vertical plane and, accordingly, reduces the efficiency of interaction with the ballast and the efficiency of the machine;

- the complexity of the design due to the presence of two buildings, their docking elements and the location of the vibration units inside the buildings.

The technical result of the invention is to increase the efficiency of the device and simplify the design by making the bodies in the form of a single rigid beam and fixing the vibration blocks on the sides of the body to the ends of the sleepers, which makes it possible to reduce the height of the body and increase its rigidity.

The specified technical result is achieved by the fact that in the device for planning and compaction of the ballast of the rubble-cleaning machine, containing two bearings located on both sides of the longitudinal axis of the machine with the ability to be reset in height, the housing and the vibrator, the housing is made in the form of one rigid beam and is installed with the possibility rotation around the vertical axis of one of the supports and fixing on another support, while two self-synchronizing vibrators mounted on the above supports are used as a vibrodrive osredstvom elastic suspension with the possibility of fixing on the lateral sides of the housing for the ends of the sleepers of the track panels. In addition, one of the supports, or both, and the housing contain two wedge joints for the gapless fixing of the housing on the vibrators with the help of a rotary lever with a drive for its rotation; the device is equipped with hydraulic cylinders that rotate the body in a vertical plane parallel to the longitudinal axis of the machine, fixed in supports and connected to brackets installed by means of vertical axes on the machine frame and can be equipped with a plow or auger with its drive for ballast planning, mounted on the body.

Figure 1 shows a General view of the device; figure 2 is a view A of figure 1 and figure 3 is a view B of figure 1.

A device for planning and sealing the ballast 1 / Fig. 1, 2, and 3 / under the rail-sleeper grid 2, mounted on the rubble-cleaning machine 3, contains two supports 4 located on both sides of the longitudinal axis of the machine 3 with the possibility of height adjustment with hydraulic cylinders 5, the housing 6, which is made in the form of one rigid beam and mounted with the possibility of rotation around the vertical axis 7, by hydraulic cylinders 8 of one of the supports 4 and fastened to another support 4 and the vibrodrive 9, while two self-synchronizing vias are used as the vibrodrive a brother installed on the above supports 4 by means of elastic suspensions 10 with the possibility of their fastening on the sides of the housing 6 to the ends of the sleepers of the rail-sleeper grid 2, which allows to reduce the height of the housing 6, increase its rigidity and, accordingly, increase the efficiency of the device compared to the prototype and simplify the design. One of the supports 4 or both and the housing 6 each contain two wedge connections 11 for the gapless fixing of the housing 6 on the vibrators 9 by means of a rotary lever 12 with a drive of its rotation, made in the form of a hydraulic cylinder 13. The device is equipped with hydraulic cylinders 14 that rotate the housing 6 in a vertical a plane parallel to the longitudinal axis of the machine 3, mounted in supports 4 and connected to the brackets 15, mounted by means of vertical axes 7 on the frame of the machine 3 to change the position of the lower wall 16 of the housing 6 relative to the horizon, which makes it possible to change the angle of attack α relative to the surface of the ballast 1 and increase the efficiency of the device. For preliminary alignment and planning of ballast 1, the device can be equipped with a plow 17 (figure 3) or a screw 18 with its drive 19 (figure 2), mounted on the housing 6. In the transport position of the machine 3, the housing 6 is mounted on one of the supports 4, is in the raised position and is parallel to the axis of the machine 3.

The device operates as follows.

After the arrival of the crushed stone cleaning machine 3 at the place of work and the cutting of the first meters of contaminated ballast 1 with hydraulic cylinders 5, the brackets 15, mounted by means of the vertical axes 7 on the frame of the machine 3 together with the supports 4 and the casing 6, mounted on one of the supports 4, are lowered to the working position and hydraulic cylinders 8 are rotated around the vertical axis 7 of one of the supports by 90 degrees, while the housing 6 is brought under the rail-sleeper grid 2 and the wedge connections 11 with the help of a rotary lever 12 located on another support 4, and a hydraulic The cylinder 13 is fixed to the support 4. The vibrators 9 are turned on and, when the nominal height of the filled ballast layer 1 is reached by the hydraulic cylinders 5, the housing 6 is pressed against the ballast 1 through elastic suspensions 10 and sealed. Depending on the height of the cast-off ballast layer, the hydraulic cylinders 14 rotate the housing 6 in a vertical plane parallel to the longitudinal axis of the machine 3, to change the angle α of the inclination of the lower wall 16 of the housing 6 relative to the horizon. So with increasing height of the ballast layer, the angle α increases. To improve the working conditions of the device, if necessary, before compaction, the ballast 1 is aligned and scanned, which is carried out by a plow 17 mounted on the housing 6 / Fig. 3/, or by a screw 18 with its drive 19 / Fig. 2/, also mounted on the housing 6. After the work is completed, the housing 6 is unfastened in one of the supports 4, rotated by an angle of 90 degrees, elevated to the transport position and the machine 3 with the proposed device is ready for movement in transport mode.
