Description

z / f j

Device for planning and compaction of ballast of crushed stone cleaning machine.

The utility model 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 its layer-by-layer compaction.

A crushed stone cleaning machine is known (see A.S. No. 1122233. E01 B 27/02), comprising a device for scheduling an excellent ballast, consisting of two endless chains installed in the bodies located on both sides of the longitudinal axis of the machine, the bodies of which are mounted on the frame can be rotated around the vertical axis and in the working position are rigidly interconnected by means of overlays, as well as a device for sealing the planned ballast, consisting of a beam located across the beam on which the vibration water mounted on the frame for chains, and the frame is equipped with drives for permutation in height.

The tasks to which the claimed utility model is directed are to simplify the design by eliminating the drive endless circuits and the combination of planning operations and ballast densification in one working body, as well as improving reliability

the operation of the device and the simplification of operation due to the plate-shaped arrangement of the working bodies of the device and their connection by means of a roller docking unit.

The essence of the utility model is illustrated by drawings:

FIG. 1 is a general view of the device, front view;

FIG. 2 - general view of the device, plan view;

FIG. 3 is a section AA in FIG. 2.

A device for planning and removing ballast of crushed stone .. the construction machine contains two supports 1 located on both sides of the longitudinal axis of the maple with the possibility of rotation around the vertical axes and height-adjustable drives 2. To the supports 1 are rigidly attached to the housing 3. In the working position of the housing 3 located plow-shaped and interconnected by a roller docking unit 4. The front walls 5 of the buildings 3 serve as ballast planning. The bottoms of the buildings 3 have a bevel equal to the draft of the ballast layer during compaction.

Inside the housings 3, with the help of spring supports 7 and articulated rods 8, vibration blocks 9 are installed. The lateral displacement of the vibration blocks 9 is limited to the bearings g 10. Each vibration block 9 contains a housing 11 and a self-balancing vibrator 12 built into it. The vibrator contains two pairs of counter-rotating unbalanced shafts 13. connected to each other by gears 14 and driven hydraulic motors 15.

of the rubble-cleaning machine to the place of work and cutting out the first meters of contaminated ballast, the bodies 3 are bent and turned around the vertical axes. They are brought into the space formed under the rail-sleeper grid until they are connected to each other by means of a roller joint unit 4. The vibrators 12 are turned on. 12. When the nominal height is reached the drive-off layer of the cleaned ballast, the actuators 2 carry out the static pressing of the vibration units 9. The front walls of the 5 buildings 3 plan the surface of the ballast for subsequent compaction of the vibration unit s 9, removing excess ballast the ends pshal.

The slit-like arrangement of the housings 3 provides the rigidity and strength of the device when abutting against a slit obstacle, and also helps to plan ballast. The vibration partially transmitted from the vibration units 9 through the spring supports 7 facilitates planning.

The roller docking unit 4 provides the connection and separation of the housings 3 by their simple rotation relative to the vertical axes and does not require additional manual connection. Moreover, due to the plow-shaped arrangement of the buildings 3, the greater the ballast resistance they experience, the denser their docking becomes. The presence of the roller 4 allows the buildings 3 to independently change their position in height, while maintaining a plow-like position in the horizontal plane.

Claims (1)
