The invention relates to vehicles and can be used on rolling stock operating on railway tracks with a large number of small radius curves.

A device is known that contains a lubricating element in the form of a rod located in a housing pivotally mounted on the support bracket 1. However, this device does not ensure the reliability of operation when passing the upper track structure and has low productivity .....

The closest technical solution to the proposed one is a device for applying lubricant to railway rails, containing an uncontaminated frame of the trolley, on which a lubricant supply source is connected, connected by a pipeline with a working body facing the inner

rail head faces 2.

The disadvantages of this device include its low productivity and insufficient reliability, due to the fact that the design of the working body does not allow the passage of turnouts and crosses, in addition, the known device does not allow uniform lubrication of the side surfaces of worn sections of rails.

Proposed; the device eliminates the above disadvantages. The aim of the invention is to increase the productivity and reliability of the device.

This goal is achieved in that the lubricating ski rail is fixed to the bracket of the trolley frame by two springs, one ends connected to the ski and the other ends by horizontal cylindrical joints connected to the brackets of the trolley frame.

Unlike well-known technical solutions, the device provides increased productivity and reliability when the device is operated in a vehicle. The absence of the indicated combination and features of known technical solutions does not allow to achieve this goal.

Figure 1 shows the device, a General view; figure 2 - depicts a ski; in Fig.Z - depicts the suspension of the ski to the non-sprung frame of the trolley; 4 and 5 show the connection of the vertical and horizontal pneumatic cylinders to each other; on figb - depicts the passage of ski cross railways. ways; figure 7 - shows the ski in plan; on fiK8 and 9 - depicts the position of the ski when passing rails with different amounts of wear.

The proposed device consists of a vehicle 1, on which a lubricant supply source 2 is located, connected by a pipe 3 to a ski 4 facing the inner edge 5 of the rail head.

The bracket 6 is mounted on the rod 7 of the vertical pneumatic cylinder 8. The housing 9 of the vertical pneumatic cylinder 8 with a clamp 10, a plug 11 and a lead 12. interconnected by axes 13, is connected to the rod 14 of the horizontal pneumatic cylinder 15. The bracket 6 is connected to the clamp 10 by means of cylindrical guides have 16.

The horizontal pneumatic cylinder 15 is mounted on the non-sprung frame of the vehicle 1 through the bracket 18.

The vertical pneumatic cylinder 8 is mounted on an arm 19, which is connected through an axis of rotation 20 to an arm 21 mounted on an unprotected frame 17.

The ski 4 is fixed to the bracket 6 by means of hinges 22 and springs 23. In this case, the ski 4 is made in such a way that it has a central horizontal part 24 on which the cavity 25 is located, connected by a hole 26 to the lubricant supply 2 through the pipeline 3.

To the central horizontal part 24 of the ski 4, the inclined guardrails 27 adjoin.

Pipeline 3 has at least one heater 28 on its way from the lubricant supply source 2 to the ski 4.

The proposed device operates as follows. The lubricant supply 2 is filled. Then, the vehicle 1 leaves for a section of the track where it is necessary to lubricate the inner faces of the 5 rail heads.

Depending on the direction of movement, a forward pair of skis 4 is included in the operation. Moving the ski 4 from the transport c. the working position is carried out by compressed air using vertical 8 and horizontal 15 pneumatic cylinders. To do this, compressed air is supplied to a vertical pneumatic cylinder 8, its rod 7 extends. Together with it, the bracket 6 with the ski 4 moves along the cylindrical guides 16. After that, the compressed air enters the horizontal pneumatic cylinder 15. The force from the rod 14 is transmitted to the leash 12 with a fork 11, interconnected by axles 13, and then through the clamp 10 is transmitted to the housing 9 of the vertical pneumatic cylinder 8.

As a result, the bracket 6 with the ski 4 is pressed against the inner edge 5 of the rail head. Since the width of the railway track; and in the conditions of use can vary within quite significant limits (from 1 $ 20 to 1560 mm), the design of the device must be able to compensate for this change in width ruts. For this, the vertical pneumatic cylinder 8 is mounted on the bracket 19 and is connected through the axis of rotation 20 to the bracket 21 located on the unprotected frame 17. The horizontal pneumatic cylinder 15 is also rigidly mounted using the bracket 21 on the unprotected frame 17. When moving the vehicle 1 such; suspension suspension ski 4 allows you to keep it in a position constantly pressed against the inner edge 5 of the rail head within the specified limits of the gauge. Served from the smear through the pipeline 3 approaches the ski 4, where through the hole 26 it enters the cavity 25 and lubricates the inner face 5 of the rail shank. .

During operation, the rails, including the inner faces of the 5 rail heads, wear out, as a result of which the rail heads change the layer of the original profile and the issue of providing a reliable contact between the cavity 25 and the inner face 5 of the rail head raises. To ensure the reliability of lubrication of the inner edge 5 of the rail head when the vehicle 1 is moving, the ski 4 is mounted on the bracket b by means of hinges 22 and springs 23.

In this case, the ski 4 due to the presence of hinges 22 constantly monitors the position of the inner face 5 of the rail head, and

ABOUT

springs 23 play the role of a damper when passing joints. The ski 4 is in motion with its central horizontal part 24 in constant contact with the inner face 5 of the rail head, and the rails are fed and lubricated through the hole 26 and the cavity 25. To ensure the normal passage of the upper track structure (crosses and turnouts), the ski 4 in its geometry consists of a central horizontal part 24 and two inclined guardrails 27.

For the operation of this device in winter conditions, the pipeline 3 is equipped with

at least one heater 28, which allows you to have a heated section of the pipeline 3, on which the viscosity of the lubricant is maintained within the specified limits, the Use of this device will improve the safety of trains, increase the service life of the rails in the curved railways. ways and wheelsets of rolling stock, and also reduce the energy costs of the railway

transport.
