Description

The utility model relates to the field of railway transport and, in particular, to devices that provide lubrication to the flanges of the wheels of rolling stock and rails in the curved sections of the railway track and turnouts.

A device for lubricating railway rails in curved sections of the track, in which the lubricant distributor is made in the form of a feed plate with grooves for the release of lubricant / see, for example, description to the USSR author's certificate No. 175524, priority dated 04/13/1962 /.

In this design of the rail lubricator, which is widely used on Russian railways, the feed plate is made of high hardness steel and is rigidly fixed relative to the rail so that its pointed upper edge 2-3 mm thick is located 10-15 mm lower than the upper level of the rail head. When the wheel of the rolling stock passes over the installation site of these rail lubricators, a pulsed supply of grease (mass from 0.1 to 0.5 grams per 1 cycle) occurs by the oil pump from the oil tank through the oil pipes to the upper edge of the supply plate. With a nominal value of the track gauge, horizontal track section and a standard (worn out) wheel profile, their flanges extend at a distance of 6 - 7 mm from the working side surface of the rail head and at a distance of 3-4 mm from the top edge of the feed plate. Depending on the mutual wear, speed or nature of the power loads on the wheelsets, this distance can increase by 5-10 times. Therefore, the contact of the flanges with the lubricated edge of the supply plate (or the grease strips protruding above it) occurs in no more than 50% of cases, even at the entrance to the curved sections of the railway track. And when installing such rail lubricators on straight sections of the railway

paths before turnouts, this contact occurs several times less often and, as a rule, only with wheelsets of skewed or “wagging” wagon trolleys. At the same time, strips of accumulated grease with a thickness of more than 3 mm often stick to the flanges of the wheels, which, after several turns of the wheel, are dumped onto the soles of the rails or the railway track, worsening its technical and environmental condition. If the grease is irregularly removed from the feed plate of these rail lubricators by the flanges of the wheels, there is an even greater excessive accumulation of it over the upper edge of this plate. Subsequently, the grease is squeezed out by flanges with minimal wear, up to the surface of the rail or flows down. This leads to a deterioration in traction and braking characteristics of the rolling stock and irrational consumption of lubricant.

In addition, in existing designs, the feed plate has a length of not more than 700 mm, because it is difficult to ensure a uniform supply of grease through the oil pipes to its upper edges with significant changes in the parameters of the viscosity of the lubricant depending on its temperature. Therefore, the wheelset flanges are lubricated at the initial moment only by 30% of their circumference. As a result of this, the lubrication on the rails of the railway track is applied unevenly, with “spots” and the length of the lubricated rails, as a rule, is several times less than required.

The objective of the proposed constructive implementation of the lubricant distributor of a device for lubricating railway rails on curved sections of the track is to ensure uniform lubrication of the flanges of the wheels along the entire circumference and, therefore, uniform lubrication of the rails of the railway track.

This is achieved due to the fact that the lubricant distributor of the device for lubricating the flanges of the wheels of the rolling stock and the rails of the railway track, contains at least two elastic elastic plates with slotted

channels for the supply of grease installed on the oil pipe or brackets along the lateral working surface of the rail head for at least one meter. Moreover, the elastic elastic plates can be adjustable, made of a multilayer or porous material, with longitudinal and / or transverse slots on the upper working edges, and fixed on the oil pipe or brackets using guides and pressure plates.

The proposed design of the lubricant distributor 5 can be used, for example, as part of a device for lubricating railway rails, containing a tank for oil (or other liquid lubricant) 1, an oil pump 2, as well as oil lines 3 and 4. The lubricant distributor 5 can be fixed along the working the edges of the rail head 11 on the oil pipe 4 and / or brackets 6 using guides 8 and pressure plates 9. It contains at least two elastic elastic oil dispensers

plates 7 made of rubber, polyurethane or other similar material, and mounted on guides 8 using pressure plates 9. Oil transfer plates 7 have a length L along the rail head 11, lying in the range from 1.0 to 3.0 meters (optimally 110 % of the circumference of the wheel), and form between them and between the rail head slotted channels 10 for supplying lubricant to the area of their contact with the flanges of the wheels. Moreover, the length L1 (along the rails) of the slotted channels 10 of the oil transfer plates 7 installed on the oil pipe 4 is several times less than the total length L of the oil transfer plates 7. For better temporary retention of lubricant on the oil transfer plates 7, to increase their flexibility, wear resistance and ability to better copy flange profile, they can be made of flexible multilayer materials. And also with longitudinal (see Fig. 7) or transverse (see Fig. 8) slots on the upper working edges. To achieve these same goals, the plate 7 can be made of elastic porous material.

The operation of the device is as follows.

When the wheel of the rolling stock passes over the installation site of this device, the oil pump 2 pulsates to turn on (from the plunger that moves when interacting with this wheel, or from the electric sensor, not shown in the drawings). And, as a result of this, a metered supply of a portion of special grease 12 is carried out through the oil pipe 4 and slotted channels 10 to the upper edges of the oil transfer plates 7. Since the flanges of the wheelsets of the rolling stock can take place at different distances from the working side face of the rail head 11, then, in some cases, the lubricant 12 entering the outer edges of the oil dispensing plates 7 can be applied immediately to the flanges (see Figs. 3 and 4). In this case, at the moment of contact of the wheel flange with the upper edges of the oil transfer plates 7, these edges are pressed against each other and a part of the lubricant is squeezed onto the flange. And the other part of the grease 12 is compressed

in the formed gap enclosed spaces 10 (see FIGS. 3 and 4) between the oil dispensing plates 7, as well as between these plates and the rail head 11, and moves wave-wise between them along these plates in the direction of wheel movement. At the same time, grease 12 is partially squeezed out with a thin layer of optimal width onto the flange of this or another wheel over their entire circumference. In subsequent interactions of the lubricated surfaces of the flanges of these wheels with the side faces of the rails in the curved sections of the track or with the sharp points of the turnouts, the grease 12 is gradually spread over an increasing distance from this device, ensuring the absence of "dry" friction in the area of their contact. At the same time, due to the elastic and elastic edges of the oil transfer plates 7, grease 12 is applied to the flanges of the wheels with a layer of no more than 1 mm, is well kept on the wheel and is not discarded when driving at high speeds, which ensures its optimal consumption when lubricating rails over a much longer length railway track.

If a significant part of the flanges of the wheels of the rolling stock will take place at an increased distance from the oil transfer plates 7, then the grease 12 accumulating in the slotted channels 10 will bend the outer of these plates, gradually bringing it closer to the flanges (see Fig. 5). This prevents it from swelling from the oil transfer plates 7 and contributes to the subsequent application of grease 12 to a much larger number of wheels, as well as to an increase in the length of the lubricated section of the rails.

The above, a positive effect is obtained through the use of non-obvious technical solutions in the design of the lubricant distributor. It lies in the fact that when applying in the design of elastic oil transfer plates 7, fixed along the working edge of the rail head 11, the effect of the wave transfer of lubricant is revealed. Grease 12 is transferred from slotted channels limited in length (size from 200 to 500 mm)

10 oil transfer plates 7 installed on the oil pipe 4, along the rest of these plates mounted on brackets 6, a distance which is 5-10 times larger than this size, and is applied to the upper working edges of the oil transfer plates 7.

The disadvantage of this device is that it is undesirable to install it in places where the wheel flange periodically contacts the lateral working surface of the rail head, because increased wear of the upper edges of the oil transfer plates will be observed. In this case, the feed plates can be set below the optimum level. But then the efficiency of the device will decrease by (10-20)%.

Thus, the use of the proposed design of the lubricant distributor in devices for lubricating railway rails on curved sections of the track allows to achieve uniform lubrication of the flanges of the wheels along the entire circumference, which contributes to the uniform application of lubricant to the rails of the railway track and, as a result, reduces their wear.
