In order to prevent wear of wheels due to friction in wheels and rails of trains (locomotives), special antiwear oil (oil) is sprayed on wheels automatically when trains run to reduce wear on wheels and rails. In the related art, in the related art, the wheels wear out due to contact friction between the wheels and the rails when the train is running, and thus the service life does not last long.

In consideration of these drawbacks, the present invention is installed on each wheel of a train (locomotive), and the distributor is operated by the automatic control device of the lubricator.The friction between the wheel and the rail is caused by periodically spraying the wear-resistant oil from the nozzle to the wheel surface. By eliminating the wheel to prevent wear of the wheel to extend the life of the wheel as long as described in detail by the accompanying drawings as follows.

That is, the solenoid valve (2) connected to the air pipe (1) is installed, and the automatic opening and closing valve automatic control device (3) is presented to the solenoid valve (2) to automatically operate the compressed air periodically The oil pipe (5) and the distributed distributor (6) were installed in the branch pipe (4) and connected to the flow pipe (7) again, and the nozzle (8) was attached to the end of the flow pipe (7). It is designed in accordance with Utility Model Registration No. 77-1177, in which compressed air and abrasion oil are sprayed at the same time by installing an air pipe 1 'on one side of the flow path pipe 7, and inside the tip of the nozzle 8, Install a plurality of fittings 10 on the outer circumferential wall of the valve gold 9 to be inserted so as to be interposed with the inner wall of the nut 11, and install a piston chamber 13 in the center of the valve gold 9, thereby adding a piston 12. ) Is inserted into the coil spring 14, and the apex 12 'is formed on the top of the piston 12 to the apex 12'. The stern chamber 13 can be opened and closed, and at the end of the piston 12, the conical head 15 is reduced, and then inserted into the channel chamber 16 to be screwed with the nut 11 and valve valve 9 ) In the outer circumference, the seat 18 is formed with several grooves 17 at the inner circumference of the hollow 18 'so that the compressed air supplied from the air chamber 19 escapes into the groove 17 of the seat 18 and the valve again. Gold (9) is to be mixed and sprayed with the wear-resistant oil in the head (15) of the piston (12) through the janggu 10 arranged on the outer periphery.

When explaining the operation effect of the present invention as described above, that is, by installing the device of the present invention next to each train (locomotive) wheel (a), when the train is run by the automatic opening and closing valve automatic control device (3) When the compressed air is periodically supplied by operating the nose valve (2), a part of the air is operated through the branch pipe (4) to operate the distributor (6) to open the valve therein. The wear-resistant oil enters the flow path chamber 16 in the nozzle 8 along the flow path piping 7, and a part of the compressed air is supplied to the air chamber 19 of the nozzle 8 along the air pipe 1 ′. .

Then, the hydraulic pressure is generated in the flow path chamber 16 and the piston 12 is pushed by the hydraulic pressure so that the coil spring 14 is reduced while the piston 12 enters into the piston chamber 13 of the valve ring 9. (12 ') seals the upper portion of the piston chamber (13) and at the same time opens the lower end of the piston chamber (13) which is blocking the head (15) at the end, and the compressed air supplied to the air chamber (19) is valve valve (9) mixed with the anti-wear oil in the head (15) of the piston (12) through the groove (17) of the valve seat (9) via the upper space (4) of the seat (18) It is strongly jetted to the wheel.

In addition, when the operation of the solenoid valve 2 (the valve is closed) is stopped according to the operation of the automatic control device of the oil lubricator opening and closing, the lubrication and air supplied are stopped, so the piston 12 installed in the nozzle 8 is coil spring. (14) It is returned to its original position by elasticity, and at the same time, the frontal head 12 'opens the blocked upper piston chamber 13, and the head 15 blocks the end of the piston chamber 13 again, so that injection of the wear resistant oil is performed. Is stopped, and the wear-resistant oil lubricated in the flow path chamber 16 is to be filled in the piston chamber (13).

In this way, the device of the present invention is installed on the side of each wheel of the train and sprays wear-resistant oil periodically during driving according to the operation of the automatic control device of the oil opener open / close valve, so that friction between the wheel and the rail is less and the wheel wear is reduced. It is fine and lasts a long time, and because of this, it consumes less wheels, thereby reducing the cost.

Claims (1)

In the nozzle 8, the seat 18 is inserted into the nut 18 with the groove 17 recessed on the inner circumference of the hollow 18 'on the upper part of the valve gold 9 in which the tool 10 is formed on the outer circumference. And a piston 12 having a coil spring 14 and an apex 12 'is inserted into the piston chamber 13 provided at the center of the valve gold 9, and the piston chamber as the head 15.
