Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic coupling device for a railway vehicle, and particularly to an oil supply device between the coupler and the lower support plate.

Conventional automatic coupling devices for railway vehicles, for example, railway freight cars for intra-plant transportation of red-hot steel ingots used in steel factories,
As shown in Figures 1 and 2 of the attached drawings, buffer springs 1 and 1
It is constructed by connecting a shock absorber 4 with a pair of companion plates 2 inside a frame 3 and an automatic coupler 5 with a pin 6.

The automatic coupling device having such a configuration includes a shock absorber lower support plate 12 fixed to a pair of beams 10 on the lower surface of the freight car body with bolts and nuts 11, and an automatic coupler lower support plate fixed with bolts and nuts 13. 14 to support the shock absorber and the automatic coupler 5, respectively, so that they can be attached to the vehicle body.

The frame 3 of the buffer 4 is placed on the opposing inner surface of the broken beam 10.
A pair of stoppers 15 are provided so as to slightly compress the buffer spring 1 via the guide plates 2 installed at both ends thereof.

The automatic coupler device thus attached to the vehicle body absorbs the shock at the time of coupling, the shock at the time of starting and stopping, or the shock at the time of towing by the buffer spring 1 housed in the frame 3 of the shock absorber 4. It is something to do.

That is, the automatic coupling device moves in the direction indicated by the arrow X-X as shown in FIG. Since the companion plate 2 on the solenoid side is fixed by the stopper 15, the impact is alleviated by the compression of the buffer spring 1.

However, such automatic coupling devices have the following drawbacks.

That is, the lower surfaces of the shock absorber 4 and the automatic coupler 5 and the upper surfaces of the lower support plates 12 and 14 that support them, respectively, wear out due to the movement of the automatic coupler. If the height of the connecting surface of the coupler 5 from the rail surface fluctuates, or if the lower support plates 12 and 14 break due to wear, it becomes impossible to connect the couplers to each other, so these problems may occur. It will become necessary to repair the area.

The present applicant has already proposed the invention of Utility Application No. 51-48816 ``Automatic coupling device for railway vehicles'' as one of the measures for this purpose, but this invention is as shown in Fig. 3. A lubricating device 30 is installed inside the frame 3 of the shock absorber 4, through which oil can be supplied to the lower support plate 12 that supports the shock absorber 4,
Although this is intended to eliminate wear on the shock absorber 4 and the lower support plate 12, no measure against wear on the lower support plate 14 has been taken.

Therefore, the present invention solves the above-mentioned drawbacks of the conventional devices and improves the previously proposed device. In particular, it significantly reduces the wear of the automatic coupler of the automatic coupler and the lower support plate that supports it. The object is to obtain an automatic coupling device that can

To this end, in the present invention, a lubricating device is attached to the side of the automatic coupler corresponding to the position of the lower support plate, and through this it is possible to supply oil to the lower support plate that supports the automatic coupler. It is characterized by this.

Hereinafter, the present invention will be described with reference to figures 4 to 7 of the attached drawings showing one embodiment thereof.
This will be explained in detail based on the figures.

In the present invention, as shown in Figs. 4 and 5, iron plates are bent on both sides of the automatic coupler 5 corresponding to the position of the lower support plate 14 into a shape as shown in an enlarged view in Fig. 6. An iron frame 41 is provided, and a metal hollow box-shaped oil supply device 42 as shown in FIG. 7 is installed inside the iron frame 41.

More specifically, as shown in FIG. Refueling port 4 that can be closed with a screw-on lid 45
6 is provided in the bottom plate of the oil tank 43, and an oil filler port 47 is further provided in the bottom plate of the oil tank 43.

- On the upper surface of the lower support plate 14 that supports the automatic coupler 5,
An oil supply groove 48 is provided in the longitudinal direction so as to communicate with an oil supply port 47 at the bottom of the oil supply device 42.

The present invention has the above configuration, and its operation will be explained next.

As shown in FIGS. 4 and 5, iron frames 41 are fixed to both sides of the automatic coupler 5 with, for example, bolts 49.
An oil supply device 42, whose oil tank 43 is filled with a lubricant such as grease, is installed into the inside of the oil tank 1 from above.

In this case, the lower surface of the collar 44 of the oil supply device 42 is connected to the iron frame 41.
Although supported by the upper edge, the bottom surface of the oil tank 43 is preferably aligned with the upper surface of the lower support plate 14 or positioned slightly above this.

In this way, when the automatic coupling device according to the present invention is installed on a freight car, shock mitigation during coupling, starting, stopping, and towing is exactly the same as with conventional automatic coupling devices. The friction between the lower surface of the automatic coupler 5 and the upper surface of the lower support plate 14, which occurs in the automatic coupler 5, is greatly reduced compared to the conventional case.

That is, in the automatic coupling device according to the present invention, the lubricant such as grease contained in the oil tank 43 of the oil supply device 42 attached to the automatic coupler 5 flows into the oil supply groove 48 of the lower receiving plate 14 provided on the lower surface thereof. This is because the contact surfaces between the lower support plate 14 and the automatic coupler 5 are lubricated, and therefore the wear between them can be significantly reduced.

According to one experience, it was confirmed that by applying the present invention to a conventional automatic coupler weighing 50 kg, for example, the interval required for repair 1 could be extended by about 4 times or more.

Further, when the oil supply device of the present invention is in use, it can be periodically removed from the iron frame 41, filled with grease, etc., and then reinstalled into the iron frame 41.

As described above, according to the present invention, the wear between the coupler and the lower support plate of the automatic coupling device for railway vehicles can be significantly reduced, and the repair interval can therefore be greatly extended. Therefore, it can greatly contribute to the operation of the vehicle.

In particular, when the present invention is implemented simultaneously with the previous invention filed by the present applicant, it is clear that the effects will be even more impressive.
