Description

A utility model relates to a machine for cleaning a crushed stone base of a rail track, having its own frame, configured to move along the rail track using running gears, and two endless cleaning chains for receiving crushed stone from the crushed stone base, which follow each other in the longitudinal direction of the machine, cover the corresponding section of the path and are made with the possibility of movement in height and in the lateral direction by means of drives, as well as transportation devices for the delivery of crushed stone, mouth DCCH for screening for cleaning ballast transport device for feeding the rubble and already purified putepodemnye devices connected to the machine frame.

A similar cleaning machine is already known from DE 4343148 A1, FR 1029167 and DD 240043 A1. This machine has its own frame, made with the possibility of movement along the rail track, and between the running gears located at its ends, there are two harvesting chains that follow directly one after another. The screening unit is located between the two harvesting chains. While continuously moving the machine forward, crushed stone is delivered along the front, first harvesting chain to the screening plant, using the second harvesting chain, soil is removed, which serves as the basis for the crushed stone ballast layer. Soil enters the transportation device and is dumped, for example, into the next carriage behind. Before dumping the cleaned gravel, sand is added to create a protective layer of the subgrade.

From the patent FR 714645, a device of four endless bucket lines is known, along which crushed stone is fed up and enters the screening plant.

Another machine is known from EP 0 629 744 B1 for cleaning works in the subway. Crushed stone, removed by a layer using the first harvesting chain, is crushed in a stone crusher, dumped onto the rail to create a protective layer of the subgrade and compacted. Using a second harvesting chain mounted on the second frame of the machine, excavation is carried out, which is replaced by a protective layer of subgrade. Then lay the path. At the next stage of work, add new crushed stone to create a crushed stone ballast base.

The objective of the proposed utility model is to create a machine for cleaning rubble of the specified type, with which they achieve an increase in the degree of purification.

According to a utility model, this problem is solved using a machine of the indicated type, which has the characteristics given in the main claim.

Thanks to such a constructive solution, it is necessary, however, on the one hand, laying the rail track for a short time to support the machine, and on the other hand, it is possible to significantly increase the degree of cleaning, while avoiding the high cost of the structure. Such significant construction costs would be necessary if both harvesting chains were placed on the same common frame of the machine, since the distance between the two running gears located at the ends should be very large so as to ensure adequate permissible rail mobility. For this reason, to increase

productivity still increased the capacity of the screening plant and the harvesting chain. With the help of a side seal, it is possible to stabilize the position of the track during the laying of the rails for a short time for safety reasons, so that travel mechanisms located between the two harvesting chains are ensured without problems. Other benefits and forms of carrying out the invention are given in other claims.

Further, a utility model is disclosed in more detail using an example implementation shown in the drawings.

Figure 1 is a schematic illustration of a machine for cleaning rubble (side view);

Figure 2 front of the cleaning machine (enlarged side view);

Figure 3 back of the machine for cleaning.

The machine for cleaning crushed stone 1, shown in figures 1-3, has its own first frame 2 and a second frame 4, which are interconnected by a hinge 3. Both frames of the machine 2, 4 are made with the possibility of movement using the running gears located at their ends mechanisms 5 along the track 7 laid on the crushed stone base 6. If you look in the working direction of the machine 1, indicated by arrow 8, then in front of the first frame of the machine 2 there is a screening car 9 connected to it with a screening machine 10.

Between the running gears 5 of the first frame of the machine 2, a first endless harvesting chain 12 is provided, arranged to rotate by means of the actuators 11 and adjustable in height, and a first hoisting device 13. A receiving end 14 of the first transportation device 15 is connected to the first harvesting chain 12,

passing in the longitudinal direction of the machine and intended for the delivery of crushed stone 16 to the installation for screening 10. Directly in front of the first harvesting chain 12 is a working cabin 18 with a control device 17.

If you look in the working direction of the machine, then the second frame of Machine 4, which is behind, is connected to the second endless harvesting chain 19, mounted between the running gears 5 located at the ends and made to rotate and height-adjustable using the same drives 11. Directly in In the area of the second harvesting chain 19, there is a second hoisting device 20 for lifting the rail 7 above the reconstructed section 21 of the crushed stone base 6. Directly in front of the harvesting chain 19 is a slave Tea stall 22 to the control device 23.

A second conveying device 24 is provided for delivering the contaminated crushed stone 16 from the second harvesting chain 19 to the screening unit 10. A third conveying device 25 is provided for delivering the cleaned crushed stone 16 with a receiving end 26 located under the screening unit 10 and an unloading end 27 located behind the second harvesting chain 19. All this is a single device for the delivery of crushed stone 28, which is installed on the second frame of the machine 4 and has a belt conveyor 29, configured to deflect Nia from the vertical axis. Immediately after the unloading end 27 is a third overhead device 36.

In the area of the rear running gear 5, on each longitudinal side of the frame there is a side seal 33 connected to the first frame of the machine 2. The side seal 33 is movable

in height or vibration by means of actuators 32. Directly in front of the side seal 33 a ballast plow 34 is provided for ballasting the ends of the sleepers 35 of the rail track 7.

To regulate both the harvesting chains 12, 19 and the hoisting devices 13, 20 in height and in the lateral direction and to set to a predetermined position, a basic system 30 with a control base 31 is barely indicated here. Such a basic system 30 is already known, for example, from patent US 6189224 , so there’s no need to dwell on it in detail.

- The following describes in more detail the method of cleaning crushed stone using a machine for cleaning crushed stone 1.

When continuously moving the machine for cleaning crushed stone 1 forward using the first harvesting chain 12, the first layer of crushed stone 16 is removed, which, using the first transport device 15, is delivered to the screening unit 10, where it is cleaned. The rail track 1, raised with the help of a lifting device 13, is then laid on the remaining crushed stone base 6, so that the running gears located behind can pass through it. In order to sufficiently stabilize the position of the track laid for this short time, ballast is added to the ends of the sleepers 35 using both ballast plows 34 located on each longitudinal side of the frame. Then this crushed stone 16, adjacent to the ends of the sleepers 35, is sealed with a side seal 33.

Along with the removal of the first layer of crushed stone, the second, remaining layer of crushed stone is removed by wave of the second harvesting chain 19, moreover, the path 7 is again lifted from the settled crushed stone base 6 using a hoist

devices 20. Crushed stone 16, taken by the second harvesting chain 19, is delivered by means of a second conveying device 24 to the screening unit 10 for cleaning it. The crushed stone 16 cleaned in the screening device 10 is fed back through the third transport device 25 to the rear end of the machine, where it is dumped through the discharge end 27 onto a raised path 7 or an open subgrade.
