Description

Automated lubricant supplying machine for rail use}

The present invention relates to a lubricator, and more particularly, to reduce wear and noise of the wheels of a rail and a train due to centrifugal force on a rail installed at a curved point of a railroad rail, and to eliminate noise. It relates to an oil lubricator that allows for automatic lubrication of lubricants such as grease of high viscosity on rails.

In general, when the train proceeds to the curved corner of the rail, the centrifugal force acts in the direction perpendicular to the direction of travel so that the train is directed in a direction perpendicular to the direction in which the train turns.

Of course, the centrifugal force of the train is caused by the rail and wheels made of metal when the train wheels are continuously rotated on the rails, causing wear after a long time. It caused pollution.

In order to solve this problem, some oil potters have been used to supply lubricating oils such as grease to the curved points of railway rails. As a method of injecting grease manually by touching the sensor while advancing, the lubricant is normally lubricated once a day.

The oil lubricator for conventional lubricants uses graphite-containing grease, which causes a lot of fouling on the rail, and uses a viscosity of about 220. There was a problem such as lowering the brake performance.

In order to apply rail using grease with high viscosity, grease must be discharged with considerable pressure. Therefore, the capacity of pumping motor requires large capacity. The development of a lubricator capable of transferring grease more efficiently and quantitatively discharging was an urgent task for the industry.

Therefore, the present invention provides an oil lubricator capable of eliminating the wear and noise pollution of the railway and wheels caused by the centrifugal force when the train proceeds to the existing railroad curving point. The present invention has been completed with the technical problem of the devise in providing a pottery which can be supplied automatically by quantity.

That is, the delivery cylinder 14 is installed on the pumping part 6, and the piston 16 connected to the motor 15 is slidably installed on one side of the delivery cylinder 14.

The piston 16 is connected to the other end of the connecting rod 19 and the shaft pin 20 mounted on the circular cam 18 axially fixed on the driving shaft 17 of the motor 15 and the motor 15, respectively. The piston 16 reciprocates on the delivery cylinder 14 by the driving of the grease, and the grease flowing into the delivery cylinder 14 through the discharge pipe 13 is sent out through the transfer pipe 21 to the nozzle unit 5. .

In addition, a pressure sensor 22 is installed on the side of the transfer pipe 21 for maintaining the discharge pressure of the grease discharged from the discharge cylinder 14 at a constant pressure to maintain the discharge pressure constant.

Of course, the signal sensed by the pressure sensor 22 is to control the driving of the motor 15 to determine the delivery pressure.

The grease sent out through the transfer pipe 21 is sent to the nozzle part 5 connected to the rear end of the transfer pipe 21 and is transferred onto the sub tank 23 formed on the nozzle part 5.

The sub tank 23 has a plurality of discharge holes 24 formed in communication with the inside of the cylinder 25 formed in the longitudinal direction on the upper side, the reciprocating movement from side to side by the electromagnet 26 can be controlled on the cylinder 25. Piston valve 27 is installed.

It is fixed so that it may be located in the vertical surface part 7a side of the part which receives centrifugal force intensively among the points.

In addition, an infrared beam sensor 35 installed on the casing 2 in which the control panel 4 is installed by separately installing a vibration sensor 34 for detecting the entry of a train at a portion where the curved point of the rail 7 starts. In addition, it can selectively detect whether the train is entering.

That is, whether or not to enter the curved point of the normal train is to be carried out by the infrared beam sensor 35, the vibration sensor in case the infrared beam sensor 35 does not detect the train entry due to failure or malfunction, etc. 34) is additionally installed as the lane detecting means.

In the figure, reference numeral 36 denotes a check valve, 37 denotes a wheel of a train,

The oiler 1 of the present invention, which can be configured as described above, is installed at a curved point of the railway rail 7 so that when the train passes through the curved point, friction and friction with one side of the rail 7 are caused by centrifugal force. To prevent the phenomenon that occurs a lot, the operation of the oiler 1 of the present invention will be described in more detail below.

When the power supply of the lubricator 1 is turned ON, the motor 15 on the pumping part 6 starts and the connecting rod 19 which is fixed to the eccentric shaft 17 of the motor 15 of the motor 15 reciprocates, A piston 16 slidably installed on the delivery cylinder 14 connected thereto performs a reciprocating motion and is connected to the discharge pipe 13 at an upper portion of the delivery cylinder 14 by the reciprocating motion of the piston 16. High viscosity (approx. 320) grease on the tank (3) is introduced into the delivery cylinder (14) through the discharge pipe (13), and the grease is transferred to the proper pressure through the delivery pipe (21) by the delivery pressure of the piston (16). It is sent out to the nozzle unit 5 at about 30kg / cm ³ ).

At this time, the upper portion of the storage tank (3) in which the grease is stored is closed in the state that the sealing cap (8) having a proper weight is maintained by the O-ring (9), the sealing cap (8) is sealed as much as the amount sent out The descent while maintaining.

The grease delivered at an appropriate pressure through the transfer pipe 21 is in the standby state in the state of being transferred to the sub tank 23 formed in the nozzle unit 5. In order to maintain the proper pressure at all times, the pressure sensor 22 on the side of the feed pipe 21 constantly checks the discharge pressure of the grease so that the discharge pressure of the grease is always maintained in the state in which the grease is filled in the sub tank 23. 15) to drive control intermittently.

Since the interlocking control of the pressure sensor 22 and the motor 15 is achieved by a general control technique, a detailed description thereof will be omitted.

When the train enters the curved point of the railway in the standby state, the infrared beam sensor 35 installed in the casing 2 detects this, and when the detection signal of the infrared beam sensor 35 is transmitted to the control panel 4. The power is applied to one of the left and right electromagnets 26 of the nozzle unit 5 so that the electromagnet 26 is magnetized, and the slider of the electromagnet 26 causes the piston valve 27 to operate on the other side of the electromagnet 26. The slide ring 28 formed in the piston valve 27 communicates with the upper and lower nozzle holes 32 and the discharge holes 29 by sliding in the direction in which the piston valve 27 is positioned. Grease discharges grease to the vertical surface portion 7a of the upper rail 7 through the discharge hole 29, the connection ring groove 28, and the nozzle hole 32, and the wheel 37 of the train Grease discharged while passing is applied to the inner surface of the wheels 37, and the At the same time during the rolling movement of the wheels 37 on the wear parts of the wheels 7, the wear of the rails 7 is prevented and the noise is significantly reduced.

When the amount of grease discharged from the nozzle unit 5 is set in advance in consideration of the R value of the curved point and the number of passengers of the train passing through the corresponding railway line, the train passes through the curved point. This can effectively reduce the wear and noise of the rails and wheels.

On the other hand, when the infrared beam sensor 35 does not detect the operation of the curved point of the train or does not operate, the vibration sensor 34 installed on the railroad detects this and notifies the control panel 4 of the train entry and transmits electricity. As described above, an appropriate amount of grease is discharged to the rail 7 vertical surface portion 7a through the nozzle portion 5.

When the proper amount of grease is discharged to the rail 7, power is applied to the electromagnet 26 opposite the electromagnet 26, which pushes the piston valve 27, which has been pushed out of the electromagnet 26, to the slider of the electromagnet 26. The piston valve 27 is pushed in the direction opposite to the opening direction, and the connecting ring groove 28 seals the upper and lower nozzle holes 32 and the discharge holes 29 at the same time to seal the outer edge of the piston valve 27 to discharge the grease. Will end.

In the present invention, the nozzle body 30 is connected to the vertical surface portion 7a of the rail 7 by using MC nylon to discharge grease to the vertical surface portion 7a of the rail 7, where the train is curved. Since the wheel 37 of the train interviews the upper surface of the nozzle body 30 while applying the grease, the grease is applied, and when the wear occurs during use, the fastening bolt 31 can be replaced by being removed. will be.

The oiler of the present invention, which can be configured as described above, automatically removes grease between the rails and the upper wheels so as to effectively attenuate the wear phenomenon and noise of the rails and the train wheels that occur when the train passes the curved point of the railroad by centrifugal force. As can be applied, the present invention, in particular, the infrared beam sensor 35 and the vibration detection sensor 34 automatically detects the entrance of the curved point of the train to the grease having a high viscosity to the piston 16 transfer pipe 21 The air is discharged through the nozzle unit, and the nozzle unit 5 is kept at the proper discharge pressure, and then the grease is discharged by a predetermined amount appropriate for the number of passengers of the train so that the wheels of the rail and the train are worn by centrifugal force. It can effectively reduce the noise, and also reduce the noise when the train passes the curvature point, and the discharge amount and discharge time of the grease are preset. As the amount of oil is automatically lubricated at a predetermined time, only replenishing the grease storage tank (3) eliminates the need for separate management, minimizing maintenance personnel and allowing the use of highly viscous grease. It is designed to prevent pollution and to contribute to environmental pollution.
