The cup cavity located under the piston is connected by a pipeline through an exhaust valve with a connecting nut with an oil tank, and through a non-return valve, a connecting nut, a hose and an inlet valve with a device for applying lubricant to the rail head, which is made in the form of a nozzle. 1 s.p. f-ly, 4 ill. ss s s 8 o

Description

The invention can be used in railway transport.

The purpose of the invention is to improve performance.

In Fig.1 shows a General view of the device: in Fig, 2 is a view along the axis of the rail; Fig. 3 is a side view; in Fig.4 - node I in Fig.Z. incision.

A device for lubricating railway rails in curved sections of the track contains a base 1 associated with it

a device for connecting the base 1 to the rail 2, including clamps 3 for interacting with the lower surface of the sole of the rail 2 and with the upper surface of the base and sets of removable crackers 4, which are mounted for placement under the base 1 for resting on the base of the rail and between the upper part base 1 and the corresponding clamps 3. On the base 1 is mounted bottom-down cup 5 with a piston

b, the upper part of which is surrounded by a spring 7 and has a recess 8 in it, in which the rod 9 is located with its lower part, connected with a device for lowering it, and in the lower part has a collar 10. The last device includes rigidly connected to the base 1 racks 11, longitudinal beams 12 pivotally connected to their upper parts, a roller 13 for interacting with the wheels of the rolling stock, mounted on the base 1 on both sides of the roller 13 of the support 14 with vertical grooves 15 through which the corresponding ends the upper parts of the axis 16 of the roller 13, mounted to interact with the respective longitudinal beams 12, and connected to their last ends and placed between the uprights 11 and the roller 13 of the rocker arm 17, with the middle part of which the rod 9 is connected. The cavity of the cup 5 is located under the piston b is connected by a pipe 18 through an inlet valve 19 with a connecting nut 20 with an oil tank 21, and through a check valve 22, a connecting nut 23, a hose 24, an exhaust valve 25 with a device for applying grease to the rail head 2. which Neno a nozzle 26.

In order to prevent the removable crackers 4 from creeping out from the action of longitudinal forces in their middle part, there is a bend equal to the diameter of the stem of the clamp 3.

The pipe 18 is a small diameter hose of oil-resistant material, which is located on the top of the sleepers. The oil tank 21 is buried in the ballast layer and is located between the sleepers inside the track. The device is covered by a casing (not shown in the drawings), which is screwed to the posts 27 and 11.

The device operates as follows.

When the rolling stock passes over the device, the ridge of each wheel presses on the roller 13, the axis 16 of which lowers along the groove 15, entraining the longitudinal beams 12 located on both sides of the roller 13. In this case, the rod 9, mounted on the beam 17, lowers and presses on the piston 6 causes the spring 7 to compress, and the collar 10 in the nozzle 5 is pressurized. At the same time, the intake of oil into the nozzle 5 by the inlet valve 19 is blocked. As the pressure increases, the outlet valve 25 located at the end of the outlet hose 24 is opened, and from the filled cavity of the nozzle 5 located under the piston b, the oil enters the nozzle 26 and is injected onto the side surface of go

rail traps and wheel flange. After the wheel has passed, the spring 7 raises the piston 6 and, accordingly, the beams 12 and the roller 13 are brought back to their initial position. When the piston 6 moves upward, the exhaust valve 25 closes and the intake valve 19 opens, and the next portion of oil is used up when lowering the rod 9, is sucked from the oil tank 21 into the cavity of the glass 5 located under the piston 6,

To ensure the operation of the device, after installing it on the rail and attaching it to the oil tank 21, manually press the roller 13 several times until the cavity of the glass 5 located under the piston 6 is filled and oil begins to flow from the nozzle 26.

As the rail head wears, crackers 4 are removed from under the base 1 and placed over the base 1 under the bracket of the clamp 3. In addition, the lubricant is regulated by changing the height of the stem 9 using the nuts and washers on the stem.

The proposed device is almost 10 times lighter than the known rail lubricator, easy to manufacture and install. There is no need to create pressure in the reservoir for supplying lubricating oil to the bead surface of the rail head. The device allows the use of various lubricating oils and, accordingly with their characteristics, adjusts the supply of lubricant. With vertical wear, the uniformity of lubricating oil supply is also regulated.
