The bar of the injection pipe 145 and the first oil supply pipe 148 Since lubricating oil is full on the connection flow path, the lubricating oil is discharged to a point where the pressure is low. At this time, the lubricating oil filled on the connection flow path between the injection pipe 145 and the first oil supply pipe 148 by the check valve 190 provided at the end of the injection pipe 145 is a lubricant storage unit 179 of the lower portion. Because it is not discharged to) is discharged toward the sliding member 164 along the first oil supply pipe 148.

In this case, since the connection flow path between the injection pipe 145 and the first oil supply pipe 148 is decompressed through the discharge of the lubricant, the check valve 190 is opened so that the lubricant stored in the lubricant storage unit 179 is injected. It is introduced into the tube 145. By repeating this operation, the oil supply pump 180 supplies lubricating oil to the upper surface of the sliding upper plate 8 as the tip rail 6 moves.

On the other hand, the automatic lubrication apparatus for the rail conversion rail according to an embodiment of the present invention is not limited to the above embodiment, but various modifications can be made without departing from the technical gist of the invention.

As described above, the automatic lubrication device of the rail conversion rail according to the present invention can automatically apply lubricant to the upper surface of the sliding upper plate only when the advanced rail is switched to the line along the sliding upper plate effectively risks various safety accidents. It can reduce, reduce the frictional resistance and has the advantage of easy line switching, has the advantage of simple installation, maintenance, maintenance.
