Description

[Detailed description of the invention] This invention relates to a cleaning device for cables from which a gondola hangs, and in particular, removes dirt, sand, etc. attached to the cables by rotating while moving relative to the cables. The present invention relates to a cable cleaning device that is capable of cleaning the cables and applying oil to the outer surface.

This invention can remove dust, dirt, etc. attached to the outer circumferential surface of the cable by rotating the brush that is in contact with the outer circumferential surface of the cable following the twisting of the moving cable. The object of the invention is to provide a cable cleaning device that can prevent rust from forming on the outer circumferential surface by applying oil, and the invention will be described below based on an embodiment shown in the drawings.

The drawing shows a cable cleaning device according to this invention, in which a vertical mounting plate 2 is fixed slightly toward the rear on the inside upper part of a frame 1 bent in a U-shape. A pair of guide rollers 3, 3' for guiding the running of the cable a are rotatably provided on the front surface of the plate 2 with a predetermined interval between their outer peripheral surfaces.

Further, between the lower ends of the parallel side plates 4 and 4' of the frame 1, there is provided an oil storage tank 7 in which a cylindrical part 6 stands up from the center of the bottom via a plurality of bolts 5. An annular felt 10 is provided between the tips and is connected to the upper plate 8 of the oil storage tank 7 and located on the upper surface of the lower plate 9 which is parallel to the upper plate 8. A wicking felt band 11 with a hanging end is provided in between. At the center of each of the upper plate 8, the lower plate 9, and the felt band 11, a hole 8', which faces the inner hole of the cylindrical part 6 and through which the cable a is inserted, is provided.
9' and 10' are respectively provided, and in the center of the felt 10, there is a center hole 10' in contact with the outer peripheral surface of the cable a.
is provided.

Above the oil storage tank 7, a fixture 14 for a rotating brush stand 13 having a large-diameter opening 12 in the center is attached by screws 15 passing through the side plates 4, 4'. A cylindrical part 13' protruding from the lower end of the rotary brush stand 13 is rotatably mounted in the part 12 with a bearing 16 interposed between it and the fixture 14. The rotating brush stand 13 is
It is formed into a cylindrical shape and has a through hole 17 in the center thereof.
At 7, there is an annular brush 18 made of a wire whose tip end protrudes inward, and the wire bundle of cables a is located below the brush 18 and is twisted with a plurality of wire bundles as shown in FIG. The wires extend radially at equal angles to each other and are always urged to protrude by the spring 19, and have an arc shape at the tip so as to match the outer surface of each wire bundle of the wire a. A pressing piece 20 having a recessed part 20' is provided, and between the guide rollers 3 and 3', the cylindrical part 6 of the oil storage tank 7 and the through hole 17 of the rotating brush stand 13 are arranged in the vertical direction. and the frame body 1
A hole 21 facing the through hole 17 is also bored in the storage surface.

Note that 22 is a mounting piece provided on the lower side between the side plates 4 and 4', and 23 is a fuel filler port with a lid provided on the front surface of the oil storage tank 7.

The cleaning device is fixed to a gondola suspended by a cable a using the mounting piece 22, and the through-holes of the cylindrical portion 6 of the oil storage tank 7, the annular felt 10, and the rotating brush stand 13 are fixed. 17. Insert the cable so as to pass through the hole 21 in the frame 1 and between the guide rollers 3 and 3'. In this case, the cable a of the portion located in the through hole 17 of the rotating brush stand 13
The tip of the annular brush 18 and the center hole 10' of the annular felt 10 are in contact with each other so as to surround the outer peripheral surface of the annular brush 18, and the number of pressing pieces 20 corresponding to each wire bundle is
The concave end portions 20' of the wire bundles are pressed against the outer peripheral surface of each wire bundle by a spring 19, and the center hole 1 of the annular felt 10 provided at the top of the oil storage tank 7
0' comes into contact with the outer peripheral surface of the cable a, and is impregnated with oil that has been filled in the oil storage tank 7 in advance through the oil filler port 23 via the felt band 11 for absorbing oil. oil is applied to the outer surface of the cable.

Therefore, if the cable a runs in the vertical direction in this state, each pressing member 20 moves along the twist of the cable, thereby urging the rotary brush stand 13 to automatically rotate, and the ring-shaped The brush 18 slides on the outer circumferential surface of the cable to remove dirt, sand, and other substances adhering to the outer circumference, and since the oil impregnated in the felt 10 is applied to the cable, the outer circumference is Prevents rust from forming on surfaces.

By configuring this idea as described above,
The annular brush automatically rotates as the cable runs and removes adhering substances such as dirt and sand, and there is no need for a rotational drive source.
It has the advantage that it has a simple structure, and since the outer peripheral surface of the cable is coated with oil, it is possible to prevent rust from forming on the cable.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention, and FIG. 1 is a vertical front view, FIG. 2 is a plan view, FIG. 3 is a right side view, and FIG.
The figure is a sectional view of the main part. In the drawings, 3 and 3' are guide rollers, 7 is an oil storage tank, 10 is a felt, 13 is a rotating brush stand, 14 is a fixture, 18 is an annular brush, 19 is a spring, and 20 is a pressing piece.

Claims (1)

[Claims for Utility Model Registration] (1) A pair of guide rollers inside the frame that rotate in the vertical direction to guide the running of the cable, and a pair of guide rollers that are located below the guide rollers and are rotatable in the horizontal direction. At the same time, a rotating brush stand having a through hole in the center for passing the cable through, and a felt provided below the rotating brush stand and having a hole in the center in contact with the cable are impregnated with oil at all times. and a top oil tank, and the rotary brush stand has an annular brush whose tip abuts against the outer circumferential surface of the cable, and a concave portion at its tip that abuts the outer circumferential surface of the wire bundle constituting the cable. The cable cleaning method is characterized in that a pressing part is provided at the same time and always presses forward and moves along the twist of the cable to apply rotational force to the rotary brush stand. Device. (2) The cable cleaning device according to claim 1, wherein the annular brush is made of wire.
