The invention relates to the construction of railways and can be used in the repair of the track with ballast cleaning.

The purpose of the invention is to increase efficiency by ensuring an even distribution of rubble along the path.

Figure 1 shows a crushed stone cleaning machine, general view; figure 2 - node I in figure 1; on fig.Z - view along arrow L in figure 2.

The crushed stone machine contains three interconnected working mobile units 1-3, which are interleaved with the help of rail chassis trucks 4 along the path 5. At the middle working mobile unit 2 connected to the drive, an endless chained scraper conveyor 6 with a drive mounted on the frame 7 of the machine. In the zone of the scraper chain bridge, Beiiepa 6 has a height-adjustable track-raising device 8. Directly behind the chain scraper conveyor 6, a working cab 9 is installed above the extraction zone of the ballast bed and connected to the frame 7 of the machine. Behind the cab is located a biasing device 10 and a device 11 for compacting rubble.

The forward in the direction of movement of the mobile unit 1 is equipped with an installation 12 for sifting with two independent installed in the longitudinal direction of the machine, one after the other in the form of a V and having (each) vibrating actuator 13. Screening equipment 12 for sieving is loaded using a belt conveyor 14 (shown short arrows) and two loading conveyor belts 15 contaminated rubble, seized by a chain scraper conveyor 6, Otslenlents from rubble in the installation 1 2. d: 1 screening material to be removed enters the belt conveyor 16 (shown in dash-dotted lines) H; 1pr11m. on the forward reloading train. From the lower CTOpLiHb installation 12 for sifting, the beginning of the crushed-stone distribution device 17, formed 1; 1 sturdy, one fixed; 1, other (indicated by long arrows) belt conveyors for transporting cleaned gravel

through an intermediate accumulator 18 to the crushed stone first output device 19 located in the area of the device 11 and to the second crushed stone output device 20 located on the rear working mobile unit 3, formed by an intermediate accumulator 21 with adjustable outlet openings. The first output device 19 is designed to form the first crushed stone layer 22 of ballast between the ballast bed and path 5, and the second output device 20 to form the second filling spike crates of the crushed stone layer 23. On the rear working unit 3 on the frame frame through the drive with the possibility of moving in the longitudinal direction, the tamping and tamping unit 24. The chipper-distributing device 17 can be extended by using a belt conveyor 25 installed behind the crushed-stone storage device 21, walking behind the rear end of the machine; and, in the front end zone, on the gripper side of the belt conveyor 25, there is a turning body. Depending on the position of this rotating body, all crushed stone (or part of it) is fed into the crushed stone drive under it 21 or through the conveyor belt 25 excess crushed stone is fed to the next transshipment car. It is advisable that all belt conveyors be made in the form of grooves, as a result of which, during transport, lateral loss of rubble or material to be removed is excluded.

The compaction device 11 consists of vertical, bearing 5 bearing pins 26 mounted on the side of the path, which are mounted on the frame of the machine and are rotatably rotatable around an axis 27 passing transversely to the longitudinal axis of the machine. In the lower part, the forked fork 26 is elongated by a stiffening beam 27, which is connected to the end of the flat sealing or scooping beam 28 installed across the path 5. The sealing device 11 is installed directly in the rubble drop zone in the first output device 19. Connected with a carrier 26 and a hinge mounted on the frame of the machine, the actuator 29 is designed to carry out continuous reciprocating movement approximately in the plane of the longitudinal direction of the track and for preliminary compaction and rubble in the opposite direction to work. Both ends of the fork carrier 26, made in the form of a fork, are interconnected by a connecting beam 30. A sealing beam shaped like a scoop for shifting crushed rubble is formed by two halves 31, made mirror-like with respect to the plane of symmetry of the machine. Each of them is mouth

On the second mass output device 20), a rotary body 42J is provided rotatably mounted about an axis passing transversely to the longitudinal axis of the machine.

Rubble cleaning machine operates as follows.

During the continuous forward movement of the entire crushed-stone cleaning machine, the contaminated crushed-stone ballast is fed up by a chain scraper conveyor 6 to the belt conveyor 14 and the dumper is dumped over it.

the end on the frame of the car carrying the tractor 26 can be rotated around the vertical axis 32 to the outside to be disengaged from the sleepers and connected to the drive 33 fixed to the carrier 26 cars. The vertical axis 32 is connected with the connecting rod 34 which can be rotated in the beam 30 and connected to its lower end with

stiffening beam 27, which is connected to the shaft 25 is dropped along the ballast with half given to it 31; the upper end of the connecting rod 34 is connected to the drive 33. Both halves 31 of the scoop beam 28 in the zone freely located in the middle of the track are connected by a detachable stiffening beam 35. The scoop beam has a convex bend 36 in cross section (viewed from top to bottom), the very bottom edge of which is in the forward direction of the convexity part in the working direction, and the top itself goes in the direction of compaction directly to the lower edge of the cross tie. Each half 31 of the scoop beam 28 is connected to the vibro-drive 37. In front of the compaction device 11, a hinging device 10 with a height-adjustment drive 39 is mounted pivotally connected to the working cabin 9 and rolling along a path using a pair of wheels with a comb 38. Installed behind the working cabin 9, the working units, as well as the movement processes, are controlled by the central control device 40.

The first output device 19 is formed by a discharge distributor with a gravity chute 41 with two outlet openings located transversely to the longitudinal direction of the path to form: two basement layers.

between the sleepers on the ballast bed, and the other part of rubble through the crushed stone 17 installed after the first output device 19 is fed to the second output device 20 for rubble. The crushed stone thrown from it through the crushed stone accumulator is used to form the second crushed stone layer and fill the sleeper crates. If, with a small amount of material to be removed, there is an excess of cleaned rubble, then unused excess crushed stone through the corresponding rotary body located above the crushed stone drive 21 is transported by the belt conveyor 25 to the transfer car located at the end of the machine. Directly

after the formation of the second crushed stone layer 23, a continuous adjustment of the position of the track and its tamping with the help of the lifting and grading unit 24 is carried out.

The crushed stone dropped in the first exit device in the area of the sealing device 11 to form the first crushed stone layer 22 is moved, previously compacted under

sleepers, in the direction opposite to the working direction, with the help of the actuator 29 of continuous reciprocating motion. Figure 2 before

its position in reciprocating motion is shown in solid, and the posterior position in the working direction is shown in dash-dotted lines. In order to precisely position the track 5 and eliminate the uncontrolled lift (under the action of compaction forces) of the sealing device 11, the pressing device 10 with a pair of wheels with ridges 38 is set to the required height position. The operator in the operating cabin can, by means of the central control unit 40, change the frequency of the reciprocating movement of the scoop beam 28 selectively in accordance with the amount of rubble and the like. Upon completion of the cleaning work, both halves 31 of the scoop beam 28 can be turned from the working position (shown in FIG. 3 by solid lines) 90 ° to the non-working position (shown by dash-dotted lines) by actuating the drives 33. The rotation is carried out due to the fact that installed in the connecting beam

30 with the ability to rotate the rod 34 by means of the actuator 33 is rotated

90 ° together with a stiffening element fixed at the bottom end. Then half turned away from the path

31 can be raised above the level of path 5, while the connecting rod of the actuator 29 will fully enter the cylinder.
