Abstract

PURPOSE:To scoop up the lubricating oil within an oil tank and automatically feed oil to the rope wire of a pulley by actuating the scooping up member within the oil tank following the revolution of the pulley in the oil feeder for an electric car wiring tension regulator. CONSTITUTION:When an aerial line is expanded and contracted by a night and day temperature difference or the like, a small pulley 9 and a large pulley 10 are revolved forward and backward and draw out or roll in wire ropes 11 and 17 to adjust the tension of the aerial line at a constant level. A follow-up pulley 24 follows up the revolution of this large pulley 10 and revolves a bucket 28. The lubricating oil 41 inside an oil tank 23 is scooped up by the bucket 28 and the lubricating oil that flows from the through hole 29 of the bucket 28 is received by means of a saucer 32 and then oil is fed to the rope wires 11 and 17 of the large and small pulleys 10 and 9 from an outlet hole 34 through oil supply pipes 35 and 36.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refueling device for refueling a tension adjustment device that adjusts the tension of overhead wires of an electric train, for example.

Generally, the tension of electric train overhead wires is adjusted by a tension adjustment device to ensure a stable supply of electricity to the electric train. As a tension adjustment device for this glaze, a rope wire that suspends a weight is inserted into a pulley, and this rope wire applies tension to the above-mentioned overhead wire. There are known systems in which the tension of the overhead wire is made constant by sending out a wire or winding a rope wire.

By the way, since the above-mentioned rope wire is used outdoors exposed to the wind and rain, it is susceptible to rust, and once rust occurs, corrosion progresses at an accelerated pace. At this time, the wires are subject to mechanical stress, which tends to cause wear and tear, and when combined with corrosion, the wear progresses extremely quickly, often resulting in wire breakage within a short period of time.

Therefore, conventionally, the rope wire is fully supplied with lubricating oil so that the entire rope wire can be wound up or pumped out smoothly, thereby preventing the wire from breaking.

However, in the past, the ropes were manually oiled once every 1 to 2 years, so the intervals were long and the effects could not be expected to be as great.
There was an inconvenience in that it was not easy to apply it even once.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to supply lubricating oil to a pulley-type tension adjustment device that automatically supplies lubricating oil to the rope wire without manual intervention by an operator. The aim is to provide equipment.

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 4. In the figure, reference numeral 1 denotes a messenger wire, and an auxiliary suspension wire 3 is suspended from the messenger wire 1 via a plurality of droppers 2 arranged at predetermined intervals. The auxiliary suspension line 3 includes a large number of hanger wires 4 and 4.
A trolley wire 5 as a power supply line is suspended via... Electric power is supplied to the Q electric car (not shown) through the trolley wire 5, and the Q electric car is made to run. In addition, the above-mentioned messenger wire 1, auxiliary suspension 1nS, and trolley wire 5 are configured as overhead wire A', and the 1200~15o

and is rotatably supported on the connecting rod 27 by a pin 30. Furthermore, an attitude changing roller 31 is provided on the upper side of the fuel tank 23 to change the attitude of the packet 28 to a horizontal state. A receiving tray 32 is provided at the lower part of this posture changing roller 31, and an outlet 34 of this receiving tray 32 is connected to the first and fifth ports which constitute the external oil supply path of the oil supply tank 23 via piping 35f. The second fuel pipe? 5, ,? It is connected to 6.

Also, the above fuel tank 2 ;? , 23 is simple oil 4
1 is stored in the fuel tank 2, and the packets 28... are stored in the fuel tank 2.
3, the lubricating oil 4 is introduced into the interior through the through holes 29 and 29.

Further, an oil storage tank 37 is provided on the lower side of the support column 7 as required, and the oil storage tank 37 is communicated with the oil supply tank 37 via a supply pipe 38. A pump 39 is attached to the supply pipe 38, and the operation of this pump 39 supplies oil 41 to the oil supply tank 37, so that the oil in the tank 23 runs out after a long period of oil supply operation. It is also possible to periodically replenish the oil beforehand, or, if necessary, to manually replenish the oil through a similar route using the pump 39.

In the above-described configuration, when the overhead wire A expands and contracts due to temperature differences between day and night, the small pulleys 9, 9 and the large pulley 10 are rotated in the forward and reverse directions, causing the wire rope 11, 17 to reciprocate. The tension of the overhead wire A is adjusted to a constant value by letting it out or winding it in. On the other hand, at this time, the driven pulley 24 is rotated by the rotation of the large boob IJJO, and thereby the packets 28... are rotated via the connecting rod 27, and are rotated by a predetermined amount to the upper part. When it reaches the position changing roller 31, it is rotated about the bin 30 and its position is changed to a horizontal state. As a result, the lubricating oil 41 flows out from the through hole 29 of the packet 28. This lubricating oil 41 flows down and is received by the tray 32, and this tray flows from the outflow hole 34 of the tray 32 through the piping 35 to the first and second oil supply pipes 35, 36, and the first oil supply pipe 35. The rope wire 11 of the small pulley 9 is supplied with oil from the pipe 35,

It may be as shown in FIGS. 5 and 6.

That is, in the figure, reference numerals 51 and 51 indicate oil supply tanks, and a pot 52 is provided on one side of these oil supply tanks 51 and 51.

One end of a cylindrical body 54 is rotatably supported at the upper end of the pot 52 via a support pin 53. The cylinder body 5
4 is open at one end, and an orifice 55 is bored at the other end. Further, eccentric cams 58 are attached to both ends of the rotating shaft 57 of the driven gooley 56 inserted into the oil supply tank 51.51, and the peripheral surfaces of these eccentric cams 58.58 are in contact with the side wall of the cylinder 54. ing.

When the large pulley 10 is rotated and the driven gooey 56 is rotated, the eccentric cams 58 and 58 are rotated, and the cylindrical body 54 is rotated about the support pin 53, thereby lubricating the inside of the cylindrical body 54. Oil 41 flows out of the opening and is directed into pot 52.

The lubricating oil 41 accommodated in this pot 52 flows from its outlet 52& to the first and second oil supply pipes, 95, . 96
The rope wires 11, 17 of the small pulleys 9, 9 and the large pulley 10 are supplied with oil via f. Note that the same parts as those in the above embodiment are designated by the same numbers and the explanation thereof will be omitted.

As explained above, the present invention provides a lubricating tank near a pulley on which a rope wire is hung, and an operating mechanism is driven by the rotation of the pulley, thereby moving a drawing member in the lubricating tank to provide lubricating oil. The rope wire of the above-mentioned pulley is lubricated with this oil through the supply path, so it operates simultaneously with the movement of the pulley, and the movable parts can be lubricated quickly.Also, since the lubricant is constantly lubricated, the progress of rust is prevented. It is slow or not at all, and can be quickly refueled when the wire rope moves to a point that is subjected to mechanical lashings. Therefore, the machine load can be reduced by 90%, progress can be suppressed, and the level of maintenance can be improved. Furthermore, since the refueling drive 1 uses the expansion and contraction force caused by temperature changes in the overhead wire, it does not require a special drive source and is therefore economical.
