TECHNICAL FIELD The present invention relates to a method and an apparatus for applying oil by spraying oil on the oil.
[0002]
[Prior art]
The so-called injection valve, which is capable of injecting oil as needed, is generally used as an injector for oil used for applying oil to the rail, that is, an injector controlled by a solenoid valve. 2. Description of the Related Art Automatic control is performed so that oil is injected when a vehicle is traveling.
[0003]
Conventionally, as a device f for detecting that a vehicle is passing through a curve, for example, there are a first example shown in FIGS. 6 to 8 and a second example shown in FIGS. 9 and 10. In the first example, as shown in FIGS. 6 and 7, a detection rod c is provided, which is responsive to a mutual rotational displacement caused by a bend of a rail between a swing pillow t and a carriage a by a link mechanism b. Is detected by a set of limit switches d and e on the swing pillow t side shown in FIG. 6, for example, and a rail curve is detected from the detection result. This makes it possible to cope with the left and right bends of the rail, regardless of whether it is moving forward or backward.
[0004]
The device f of the second example shown in FIGS. 9 and 10 uses a pair of photoelectric switches h and i on the side of the swing pillow t to determine the change in the rotation angle of the reflector g provided on the side of the carriage a with respect to the swing pillow t. To detect it.
[0005]
On the other hand, the device f in the bolsterless truck j as shown in FIG. 11 cannot be detected by the method of the first example or the second example because the vertical swing of the truck j is also affected. Therefore, as shown in the drawing, it is necessary to provide, for example, a reflection plate g and a photoelectric switch i for detecting the vertical inclination of the reflection plate g on the carriage a and the vehicle j, and to correct the swing of the carriage a based on the detection result. is there.

[Problems to be solved by the invention]
However, in the above-mentioned first example of the related art, the mechanical parts and the frictional parts are often worn and cannot be accurately detected. Therefore, much labor and time are required for inspection and maintenance for the corresponding maintenance, and the maintenance cost is increased. In the second example, there is no friction portion and no maintenance for wear is required, but further malfunction is required because the sensor malfunctions due to contamination of the sensor by dust or the like. In the example of the bolsterless truck a shown in FIG. 11, it is difficult to correct the swing of the truck a.
[0007]
Apart from these, oiling is performed by detecting a bending in the traveling direction of the vehicle using an angular velocity sensor using a piezoelectric element. However, for the piezoelectric element, a moving body is arranged between fixed plates installed in the direction of the angular velocity to be detected, and the piezoelectric element is sandwiched between this moving body and each fixed plate, and the inertial force of the moving body when the vehicle changes direction is Is applied to the piezoelectric element to detect the angular velocity, so that the vertical movement of the vehicle or bogie that works on the moving body generates noise, so there is no problem of friction or dirt, but it is easy to make an erroneous detection, so for practical use Advanced correction technology is required.

Since the function of automatically and stably applying proper lubrication based on the detection of the yaw rate of the vehicle 1 by the non-contact gyro sensor 3 is not impaired, the necessary equipment is compacted, and the mutual piping and wiring are simplified. In addition, the operation of attaching the vehicle 1 can be performed easily and in a short time, and the cost can be reduced. In particular, assembling the oiling device itself and attaching it to the vehicle 1 can be further simplified by assembling it into a single unit as shown in FIG. I do.

The oil supply means 12 supplies the compressed air stored in the air tank 24 to the oil storage tank 11 by reducing the compressed air to the oil application reference pressure by the pressure reducing valve 25. As a result, compressed air having the oil application reference pressure is obtained by sharing the existing air tank 24 used for other applications, and automatic oiling can be performed without requiring a special compressed air source.
