DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic lubricating device for a switching part, which is a switching part of a track on a railway line.

[0002]

2. Description of the Related Art In a track switching operation at a switch point, a switch is performed by sliding a moving track on a floor board (switch board) by operating a switch, and switching is performed several hundred times a day by a switch. Where the operation was performed, the lower surface of the track and the floor plate surface were severely damaged by friction, and smooth sliding was not performed. In order to prevent this damage, lubricating oil is usually applied on the floorboard surface. However, conventionally, in the case where oil is supplied every time a switchover is performed, the oil is excessively supplied in places where the number of times of point switching is large, causing oil accumulation on the floorboard.

[0003]

If an oil stagnation occurs at a switch point, the oil scatters every time a train passes and contaminates the vehicle and its surroundings, and when dust and dirt are mixed in the oil. Sliding of the moving track on the floor plate has become difficult, which has caused failures such as inability to switch tracks. SUMMARY OF THE INVENTION It is an object of the present invention to provide an automatic lubricating device for a switch section which prevents oil pools on a floor plate and reliably prevents smooth movement of a moving track. Another object of the present invention is to provide an automatic refueling device at a switch section which can prevent oil pollution of a passing train.

[0004]

The above object of the present invention is achieved by the following structure. The configuration is such that in an automatic lubricating device that automatically supplies lubricating oil to a moving area of a moving track that slides on a floor plate with the operation of a switch, at least one lubricating oil drop port is provided in a part of the bottom plate. A supply container, an oil supply member provided with at least one supply hole, rotatably housed in contact with the lower surface of the bottom plate of the supply container, and an oil supply member rotatably housed. A replenishing member having a long hole for dropping the lubricating oil filled in the supply hole at the bottom surface, and a lubricating oil intermittently dropping from the long hole of the replenishing member is spread over the entire width for extending in the longitudinal direction and uniformly. A guide plate which is inclined so as to flow down and is provided below the replenishing member, and is disposed at a lubricating oil drop position along a lower edge of the guide plate, and one oil groove is formed in a spiral shape, Both ends are rotatably supported by the automatic refueling device main body. The rolling roller of the automatic lubricating device main body, which moves along with the movement of the moving track, moves while rolling on the floor plate, and the rolling roller moves the lubricating oil on the floor plate. And the rotation of the rolling roller is reduced and connected to the replenishing member, and the lubricating oil in the replenishing container is intermittently supplied from the oil supply hole of the oil supply member and the passage hole of the replenishment member. And is supplied to the rolling rollers while extending on the guide plate.

[0005]

Since the automatic switch lubricating device of the present invention is constructed as described above, it is screwed and arranged on the floor plate in the vicinity of the inside of each of the pair of tracks, and as the respective tracks move. The rolling roller of the automatic refueling device rotates in contact with the floor plate surface. The rotation of the gear fixed to the end of the rolling roller is reduced by a plurality of reduction gears and transmitted to the oil supply member. With the rotation of the oil supply member, the lubricating oil in the replenishing container passes through the drop opening of the replenishing container, the supply hole of the oil supplying member, and the lubricating oil in the replenishing container at a position where the opening and the supply hole face each other. Is filled in the supply hole, and the rotational motion transmitted with the rotation of the rolling roller rotates the oil supply member and gradually flows down from the long hole of the supply member to the guide plate provided below. Lubricating oil flows down on the surface of the rolling roller abutting on the lower edge of the guide plate, and the lubricating oil is guided into an oil groove formed in the surface of the rolling roller and applied to the floor plate surface. Therefore, the track by the switch machine can move smoothly.
The amount of lubricating oil applied at this time is controlled by the number of revolutions of the oil supply member, and since this number of revolutions is transmitted with the rotation of the rolling roller rolling on the floor plate being reduced, the supply of lubricating oil is It is to be applied in a limited amount. As shown in FIG. 1, in the automatic switch lubricating device according to the present invention, a replenishing container is disposed at a position lower than the height of the track, and the position of the oil supply member is set below the lubricating oil replenishing container. Since it is arranged on the floor side, it can be moved to a position where it does not hinder the movement of the vehicle body rolling on the track.

In another embodiment shown in FIG. 5, when the supply groove 5e of the supply roller 5b as the oil supply member 5 reaches a position facing the slit-shaped opening 4 formed in the bottom plate 3 of the supply container 2, the supply container The lubricating oil in 2 falls into the supply groove 5e and fills the supply groove 5e. Further, when the supply roller 5b rotates and the supply groove 5e is positioned at the bottom hole slit, the lubricating oil falls onto the guide plate 11 and flows.

The rotating member 5a or the replenishing roller 5b of the oil supply member 5 rotates slowly because the gear 7a of the rotating shaft 7 is reduced in rotation of the gear 12 of the rolling roller 9. With this rotation, the lubricating oil in the supply hole 5c and the supply groove 5e overflows and flows down on the guide plate 11, and flows on the rolling roller 9 while diffusing on the guide plate 11 surface. The lubricating oil flowing down is filled in the spirally formed oil groove 10 of the rolling roller 9, and the rolling roller 9 rolls on the floor plate 21 at the moving speed of the track 20. Is applied to the floor plate 21 surface. Similarly, lubricating oil is applied to the floor plate 21a by the automatic lubricating device main body 22a provided near the other track 20a and connected by the connecting rod 23. Since the rotation of the rolling roller 9 is reduced by the reduction gear 13 and transmitted to the oil supply member 5, the rotation of the rolling roller 9 is reduced.
The replenishment of the lubricating oil is not applied onto the floor plate 21 every time the track 20 moves, but is supplied at predetermined intervals. A ratchet may be arranged on the rolling roller 9 or a clutch mechanism may be provided to rotate the gear 12 by one-way rotation.

In the above embodiment, the opening 4 of the supply container 2
Although one is provided in FIG. 4, it controls the amount of lubricating oil supplied to the floor plate surface, and a plurality of may be provided. Although four supply holes 5c are formed in the rotating body 5a, they can be appropriately provided according to the rotating speed, and the present invention is not limited to this. Although the long hole 8a of the replenishing member 8 is formed in an arc shape, it can be designed in any manner depending on the number of revolutions of the rotating body. can do. As the lubricating oil used in the present invention, the lubricating oil conventionally supplied on the floor plate of the switch part can be used, but a low-viscosity oil is particularly preferable. Since the speed reduction mechanism of the automatic switch lubrication system of the present invention is concealed by the cover 14, the transmission of rotation is always stable without being affected by dust such as sand on the track.

[0012]

As described above, in the automatic switching unit lubricating apparatus according to the present invention, the lubricating oil is applied onto the floor plate by the rolling rollers which roll in connection with the operation of the switch, and the amount of the lubricating oil is reduced. Since it is controlled by the decelerated oil supply member, no excessive lubricating oil is supplied, so that oil splattering due to the passage of the train can be suppressed without generating an oil pool on the floor plate surface. Instead, the rolling rollers rotate only in one direction, so when they do not rotate, the floor plate surface will be cleaned, and the floor plate surface will always be cleaned, so the track will move smoothly, and the train It has an excellent effect, such as being able to prevent derailment accidents and the like at the switch point.
