Abstract

The invention relates to railway transport, in particular, to machines that perform work on the cleaning of crushed stone ballast from contaminants. The purpose of the invention is to expand the functionality by cleaning the rubble of the shoulders and the inter-steps of the ballast section with the dosing of the selected and cleaned rubble. The invention allows to reduce the energy consumption required for the promotion of the crushed stone by reducing the cutting resistance of the crushed stone ballast and allows loading into the rolling stock; previously cleaned crushed stone. The device installed above the scoring knife destroys the prism of a lug drawn in the process of cutting gravel ballast and advances the cut out volume of gravel to the feed conveyor, thereby reducing the resistance from cutting gravel. The device for breaking the prism of the drawing is made in the form of a horizontal shaft mounted on the supports with rigidly mounted on it in a checkerboard pattern; rotors made in the form of rays welded to the sleeves, terminating in rectangular plates, the flat surface of which is perpendicular to the direction of rotation of the blade. 5 il. . about S (L with:

Description

The invention relates to railway transport, in particular, to machines that perform work on the cleaning of crushed stone ballast from contaminants.

The purpose of the invention is to extend the functionality by cleaning the rubble of the shoulders and the interpipe of the ballast prism with dosing of the withdrawn and cleaned rubble.

Figure 1 shows a crushed stone cleaning machine, side view; Fig. 2 shows a device for breaking a prism of dragging and moving rubble to a feed conveyor; in FIG. 3, a device for breaking a drawing prism; in FIG. 4, section A-A in FIG. 3; Fig. 5 shows a guide element.

The crushed stone machine consists of two frames 1, chassis trucks 2, control cabins 3, power station 4, two devices 5 for removing crushed stone ballast, two intermediate conveyors -6, two screens 7, two discharge conveyors 8, two dispensers 9, a horizontal inclined conveyor 10, two planners 11, dump conveyor 12, receiving hopper 13.

The device for excavation of crushed stone ballast consists of a cutting knife 14, a feeding conveyor 15, in a manner used to destroy a drawing prism 16 (Fig. 1).

A device for breaking a prism of a drag and advancing a crushed volume onto a feed conveyor consists of two supports 17, a shaft 18, and rotors 19 (Figures 2 and 3). The rotors 19 are mounted on the shaft in a checkerboard pattern and are made in the form of rays 21 welded to sleeves 20, ending with rectangular gshastins 22 (Fig. 4). The device is driven by the feed conveyor chain.

The dispenser consists of a guide element in the form of a bar 23, a storage bin 24 and metering funnels 25. A guide element is located after the rumble between the storage bin and the horizontal inclined conveyor (Fig. 5). It is hinged to the dispenser frame by means of a screw transmission. The dispensing guide element changes its position in the vertical plane with the help of a screw and a drive rod.

ki, section and sent a stream of clean rubble depending on the type of work.

Using the guide element. the crushed stone is directed either to the storage bin, or to the horizontal inclined conveyor, or to the storage bin and to the horizontal-inclined conveyor at the same time in any proportion.

Devices for the extraction of crushed stone ballast, intermediate conveyors, screens, dispensers, discharge conveyors and planners are located on both sides of the axis of symmetry of the machine.

The dump conveyor is mounted on a turntable and rotates around an axis by 90 in both directions.

The crushed stone machine is designed to clean the ballast prism shoulders and can perform the following types of work:

cleaning of the rubble of the shoulders and between the paths of the ballast prism on the hauls and station tracks with the dosing of all the collected and cleaned rubble back into the road;

cleaning the rubble of the shoulders of the ballast prism on the hauls and station tracks with the dosing of part of the collected and cleaned rubble back into the way and the selection of the remaining part into the rolling stock;

cleaning the rubble on the shoulders of the ballast section on the tracks and station tracks with the selection of all cleaned rubble into the rolling stock.

The last two variants of the operation of the machine with the possibility of selection of excess rubble from the ball- prism of prism. They want to lower the path in places where it is re-lifted.

When the machine is running, the loader deletes:

at the station tracks, to the rolling stock, which is located both on its own and on the adjacent track (along a horizontal inclined and dump conveyor); on the tracks - out of the way (with the help of the exhaust conveyor) and into the rolling stock (when working in the excavations).

The machine works as follows.

Carved from the shoulders of the ballast prism rubble with a cutting knife 1D

The feed conveyor 15 and further along the intermediate conveyor 6 is fed to the screen 7, where the rubble is cleaned from the polluter. Further, depending on the type of work, using the plank 23 of the guide element, crushed stone is supplied: I

in the storage hopper 24, followed by dosing it into the path with metering funnels 25;

during selection, a piece of rubble into the rolling stock guiding element directs a part of the cleaned rubble into the storage bin 24, and a part onto the horizontally inclined conveyor 10, and from there through the dump conveyor 12 into the rolling stock;

when loading all cleaned rubble into the rolling stock, the guide element guides all rubble to the horizontally inclined conveyor 10, and its through the dump conveyor 12 to the rolling stock.

The discharge conveyor 8 is located under the screen perpendicular to the axis of the machines. During the operation of the rubble cleaning machine on the stretch, the contaminant falling on it is thrown out of the railway line with a crash. When working on station roads, the exhaust conveyor is moved along the tracks to the side, the contaminant gets on a horizontal inclined conveyor located under the exhaust conveyor, then through the dump conveyor the contaminant is removed to the rolling stock.
