The proposed solution relates to the field of railway equipment, namely, operation of machines for cutting railway ballast means for cleaning the ballast section.

Known [1. The Rudolf childer and Franz, Peredur. Recovery of the primary site by using cut-out machine AMN 800-R. Special pubic circuits //Path and track facilities, 1999, No. 2, S. 18-19] a method of operating a machine designed for cleaning ballast from weeds, including: 1 - the installation of the assemblies of machines of the respective replaceable items (such the most wear items primarily include rippers mounted on the bar circuit; sliders that change the location of the cutting chain; lead sheet lining on the ascending chute, clerk for directions to be removed from under the gravel path in the upward groove; the lining of the rising trough; lining downstream of the gutter), 2 - the operation of the machine for cutting gravel (ballast under way to transport it up the chute, screening of pollutants and fine fractions, the return of suitable ballast in a top-down groove back under way), 3 - subsequent stopping of the machine when reaching the maximum permissible wear some sort of replacement item (for example, rippers), 4 - replacement of this element on new - 5 re-work of the machine, 6 - following its shutdown when reaching the maximum permissible wear of the next element (e.g., lead-sheet), 7 - replacement of this element, 8 - re-work of the machine, and so on,

Thus, the method of operation is an uneven C is Yong. Thus, during operation of the machine before replacing the lining of the descending chute may need X-replacement of rippers, Y-replacement bearer, Z-replacement of lead sheet, i-replacement of the lining of the rising gutters, etc.

From the description of the method shows that the disadvantage of this method of operation is the low productivity of the machine because of the frequent (and not coinciding in frequency and duration) stops the machine.

The technical result of the proposed method is to increase the productivity of the machine by reducing the number of shutdowns. This is ensured by the selection of such materials, their physical and mechanical properties, thickness, and construction of replacement elements, which provide the specified managed resource is equal for all elements or for multiple groups of elements.

In Fig.1 shows a graphical illustration of the dependence of the relative intensity of wear of the elements from the path traveled by the machine in operation at the actual method of operation of the machine; Fig.2 - the same, with the proposed method with equal resistance elements of Fig.3 - the same, with multiple resistance elements.

Assuming the machine has the most wear items rippers, lead sheet, lining upward gutters, futerovk which is 40 km. When this lining is made in the form of a facing sheet thickness t1of steel 110G13L steel (Gatfield, its physical-mechanical characteristics, such as strengthinthe wear resistance To ahthe fracture toughness K1Cknown). Put this durability L1constant, while the intensity of wear time varies according to certain regularities described by curve 1 in Fig.1.

The maximum effect was achieved if the resistance of other elements was the same, i.e., L1. This would stop subpotential car only every 40 km and to replace all items at once. But each of these other elements has its own design, material and so on, therefore, the intensity of wear will be time to proceed through the different dependencies. It is desirable that their periods of resistance coincided with L1. To achieve this it is possible, by changing the design elements, the material, its physical and mechanical properties, thickness. So. for example, a simple increase (t1) thickness t2lining the rising of the gutter (it unlike the downward trough moving small factions and weeds Bologna to achieve replacing steel 110G13L to another (heat), with a higher physical and mechanical properties such as abrasion resistance.

In order to achieve the required technical result, the resistance of the lead sheet (it usually does not exceed 15 km) can be increased to L1by changing its design (reinforced with hard alloy all or part of the surface, be equipped with wear-resistant surfacings, and so on), material (apply complex alloyed or tool steel, and so on), its physical and mechanical properties (wear resistance and crack resistance), thickness. For example, the housing lead-sheet structural steel, reinforcing its intake side plates made of hard alloy and the working surface waste (scrap) solid alloy will increase its resistance. The choice of the brand (physico-mechanical characteristics) hard alloy, its thickness t3, (or fractions of a square reinforced waste) will allow to achieve the required period of L1resistance (curve 3).

Similarly, the resistance (7-10 km) rippers a bar chains, especially those located in the lower row can be improved by reinforcement of the hull Ripper carbide tip made of a correspond to the d2case (curve 4). Also can be equipped with hard metal sliders (the original curve 5).

Machine work with these elements is as follows. As tenderloin ballast under railway tracks, transport of ballast in the upper chute, the filtration of the fine fraction and weeds, return suitable ballast in a top-down groove back under way all of these elements of the device are exposed to wear. He runs through his (curves 1, 2, 3, 4 and 5) patterns and at some point (L1time reaches a critical (maximum) values for all elements. Subpotential machine stop and are replaced all the worn-out elements, i.e. (instead of multiple stops, as in the prototype) reduces the number (and total time) of the machine downtime, which proves the achievement of the technical result.

Private case management (job) period of resistance elements may be an example of such a design (design, material, and so on) elements, when their resistance is a multiple of the least resistance wear element, Fig.3.

So, in Fig.1 shows the wear pattern of the existing elements. It is seen that the resistance of Lthe programme downward gutters have to stop three times (points 10, 11, 12) to replace the rippers, three times (points 13, 14 and 15) to replace lead-sheet, two times (point 2 L5for replacement bearer once (point 16) for relining washedaway gutters and once (point L1to replace the lining of the descending chute. To achieve a technical result, you can choose several options. The simplest for the case shown in Fig.1, obviously, will be to align resistance (L3= L4=Li) rippers and lead-sheet, align resistance (Ls=L1=L2=Lj) inserts the upward and downward gutters, to make them multiples of (Li/Lj=k) and choose the size ratio (e.g., k=1/3). Such an example is shown in Fig.3. To achieve a variety of design solutions. For example, the Ripper to equip inclined located carbide plate and the working surface of the lead sheet to provide longitudinal (along the course of the rubble) wear-resistant surfacings and transverse (or inclined). Welding can be of different height, width1and in2to be located on different l1and l2distances (depending on the places of heavy wear). Similar deposits (and/or ar is and the method of operation of the machine will be implemented as follows. After reaching (Lithe minimum wear make one substitution (point 1 in Fig.3) rippers and lead sheet, then over the same period (2Li) change them again (point 2 in Fig.3) and at some point in time, Lj=3Liat the same time change the rippers, lead sheet, lining upward and downward gutters and sliders. The number of shutdowns of the machine is smaller than in the case represented in Fig.1, which confirms the achievement of the technical result.

SUBSTANCE: proposed method consists in that granular loose material is compacted and/or cleaned of impurities by forcing pressurised medium in material layer prior to and/or during processing. Said forced medium can represent gas and/or fluid and/or mix thereof except for cleaning wherein fluid and/or gas-fluid mix is used as said forced medium. Composition of forced medium is varied during processing granular loose material. Said medium is forced into granular loose material in steady-state or pulsed conditions, pulsation being caused by fed medium pressure variation and/or by alternating medium feed and feed stoppage intervals. Said medium is fed under pressure that ensures quasi-liquefaction of granular loose material.

EFFECT: reduced friction between material grains that minimises complex spatial motion of said grains.
