DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil pan cleaning device for a passenger conveyor for cleaning an oil pan provided on an escalator or a moving road.

[0002]

2. Description of the Related Art In a conventional passenger conveyor oil pan cleaning apparatus, a swingable support arm extending rearward is provided on a front wheel axle of a step, and a rubber member is attached to a tip of the support arm. By moving the support arm, the rubber member collects dust on the oil pan.

[0003] Incidentally, as this kind include those described in, for example, JP Sho 56-3274 Patent Publication.

[0004]

In the conventional oil pan cleaning apparatus for a passenger conveyor described above, a relatively soft member such as a rubber member slides on the oil pan to collect the dust. Although dust could be removed, it was difficult to remove dust stuck on the oil pan. Further, since the rubber member is disposed between the pair of guide rails for guiding the front wheel shaft, only a limited portion of the oil pan is cleaned.

[0005] The present invention has been made in view of the circumstances in the prior art, as its first object, a wider
It is an object of the present invention to provide a passenger conveyor oil pan cleaning device capable of removing dust stuck on the oil pan over a range .

It is a second object of the present invention to provide a passenger conveyor oil pan cleaning device that can more effectively remove dust on the oil pan . Also, third object is that the interval between the guide rail and the oil pan to provide an oil pan cleaning device also applicable passenger conveyor different.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a passenger conveyor oil pan cleaning apparatus according to an embodiment of the present invention.

FIG. 1 is a perspective view showing an embodiment of a passenger conveyor oil pan cleaning apparatus according to the present invention, FIG. 2 is an explanatory view for explaining the operation of a scraper in a rail bracket portion, and FIG. 3 is a cleaning procedure for oil pan cleaning. FIG. 4 is an explanatory diagram illustrating a state in which the oil pan cleaning device is attached to the escalator.

Generally, as shown in FIG. 4, a passenger conveyor, for example, an escalator 1, is disposed below a plurality of steps 2 connected endlessly and a reversing traveling position where the steps 2 travel in an upside-down state. Each of the steps 2 includes a front wheel 5 running on a guide rail 4, a front wheel shaft 6 interposed between the front wheels 5 as shown in FIG. And a bearing 7 attached to the wheel shaft 6.

As shown in FIG. 1, the oil pan cleaning apparatus according to the present embodiment has a mounting body 10 whose rear portion is detachably mounted on the front wheel shaft 5 of the step 2 and which is inclined obliquely forward.
The mounting body 10 includes left and right plates 10b, 10c, a rear plate 10d, and a bottom plate 10a.
And dust storage units 10f and 10g formed by an intermediate plate 10e erected and reinforced between the left and right plates 10b and 10c,
The rear plate 10d includes a bracket 10h that is engaged with the front wheel shaft 6, and a bolt 10i that is screwed to the bearing 7 via the rear plate 10d. In addition, a scraper 11 is provided which partially overlaps with the lower surface of the mounting body 10 and is rotatably mounted on the lower end of the mounting body 10 and abuts on the upper surface of the oil pan 3. Is rotatably attached to the lower end portion of the scraper via a spring-loaded hinge 12 that presses the scraper in the oil pan direction. In addition, scraper 1
1 is larger than the width of the mounting body 10 and extends below each guide rail 4 for guiding the front wheel 5.

In this embodiment, when cleaning the oil pan 3, first, as shown in step S 1, a safety fence is installed so that a third person other than the worker does not enter the upper and lower entrances of the escalator 1. . Next, as step S2, while removing the cover plate provided in the upper machine room 1a,
Remove three steps 2.

Thereafter, the front wheel shaft 6 located at the center where the steps 2 are removed is moved to the upper machine room 1a. At this position, the bracket 10h of the mounting body 10 is engaged with the front wheel shaft 6 in step S3. The rear plate 10d is fixed to the bearing 7 with bolts 10i, and the scraper 11 is installed so as to contact the upper surface of the oil pan 3. In this state, the procedure S
As shown in FIG. 4, the escalator is operated at a low speed, the mounting body 10 is moved from the upper machine room 1a position to the lower machine room position, and the scraper 11 is slid on the oil pan 3 upper surface. Remove dust. At this time, as shown in FIG.
Portion protrudes from 0, in contact with rail brackets 4a of the guide rail 4, to rotate the scraper 11 in the direction indicated by the arrow A the spring containing the hinge 12 as a pivot axis
In addition, the mounting body 10 also has an
It turns in the direction shown by B. Thereby, the scraper 1
1 is for sliding the gap between the rail bracket 4a and the oil pan 3
Since it moves so as to come off , it does not catch on the rail bracket 4a.

Next, as shown in step S5, the cover plate of the lower machine room is removed, and in step S6, the bolt 10i is removed, and the mounting body 10 is removed from the front wheel shaft 6. Thereafter, in step S7, dust collected in the lower machine room by the mounting body 10 is removed, and in step S8, a cover plate is mounted on the lower machine room, and the front wheel shaft 6 on which the mounting body 10 is mounted is removed from the upper machine room 1a. Then, the steps 2 removed in step S9 are mounted on the respective front wheel shafts 6. Next, in step S10, the upper machine room 1
Attach the cover plate to a, remove the safety fence in step S11, and end the cleaning work.

In the present embodiment configured as described above, dust stuck on the oil pan 3 can be removed. Further, since the scraper 11 is pressed in the direction of the oil pan 3 by the spring-loaded hinge 12, dust on the oil pan 3 can be more effectively removed. Further, by making the scraper 11 larger than the width of the mounting body 10 and extending below the guide rail 4, dust on the oil pan 3 can be removed over a wider range.

FIG. 5 is a perspective view showing another embodiment of a passenger conveyor oil pan cleaning device. The same components as those shown in FIG. 2 are denoted by the same reference numerals.

FIG. 5 shows an oil pan cleaning apparatus according to another embodiment.
As shown in FIG. 1, an auxiliary member 13 is provided between the mounting body 10 and the front wheel shaft 6.
Has left and right plates 13a and 13b, a front plate 13c, and a rear plate 13d. The rear plate 13d is provided with a bracket 13e that engages with the front wheel shaft 6, and the front plate 13c
The above-mentioned bolt 10i is screwed. Further, a bolt 13f screwed to the bearing 7 via the rear plate 13d is provided.

In another embodiment, the guide rail 4
When the distance between the oil pan 3 and the oil pan 3 is large, the bolt 10i of the mounting body 10 is screwed into the front plate 13c of the auxiliary member 13, and the mounting body 10 and the auxiliary member 13 are connected. 13e is engaged with the front wheel shaft 6.

In another embodiment configured as described above, it is possible to cope with a passenger conveyor in which the distance between the guide rail 4 and the oil pan 3 is different.

[0024]

According to the first aspect of the present invention, as described above, dust stuck on the oil pan can be removed over a wider range. since it is configured as in the invention is more described in 2, more effectively can remove the dust on the oil pan, by this, to ensure clean upper oil pan, dust loading on the oil pan This can prevent adverse effects such as blurring caused by fire of cigarettes.
