Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to passenger conveyors such as escalators and moving walkways, and in particular, to a drainage device for passenger conveyors that drains water that has entered outdoor passenger conveyors. It is related to.

[Prior Art] In recent years, passenger conveyors are often installed outdoors, such as in station plazas and playgrounds. In this type of passenger conveyor installed outdoors, when it rains, the rain is directly insulated from the passenger conveyor, and the rainwater enters the lower part of the main frame through the gaps between each piece of equipment.

A device for discharging this infiltrated water will be explained using FIG. 5.

FIG. 5 is a schematic diagram showing the overall structure of the escalator drainage device.

In the figure, (1) is the building where the escalator is installed, (2) is the main frame of the escalator, and (2a) is the main frame (
2) a step attached to a conveying means arranged in (

5) is the lower oil pan.

In the elevator drainage system configured as described above, when the infiltrated water (L) falls onto the upper oil pan (3) and the inclined oil pan (4), it flows downward and drains into the lower oil pan (5). stored above.

However, at this time, oil coming out of the escalator mechanism gets mixed into the infiltrating water (L) on the upper oil pan (3), inclined oil pan (4), and lower oil pan (5). Infiltrated water (L) accumulated in the oil pan (5)
) cannot be discharged as is.

C: In view of the above circumstances, a device as shown in FIG. 6 has been known.

FIG. 6 is a sectional view of a main part showing a drainage portion of a conventional escalator drainage device.

In the figure, (5a) is a discharge hole formed in the lower oil pan (5), (6) is a pit provided in the building (1), and (7) is a pit (

The conventional elevator drainage system configured as described above operates as follows.

First, the infiltrated water (L) on the lower oil pan (5) flows into the oil-water separator (7) through the discharge hole (5a), where the oil is separated from water and further removed. Water (L,
) is discharged as wastewater (D).

[Problems to be Solved by the Invention] However, according to the above-mentioned conventional elevator drainage device,
Since the piping where the oil/water separator (7) is installed (6) is included in the category 4 of the building (1), there is no agreement between the builder and the escalator contractor regarding the specifications of the drainage part. It was necessary to perform a detailed n-matching. Furthermore, as is clear from FIG. 6, since the oil/water separator (7) is located downwardly away from the lower oil pan (5),
When inspecting or cleaning the oil/water separator (7), it was necessary to extend the hand to the back of the drain hole (5a).

Therefore, an object of the present invention is to provide a drainage device for a passenger conveyor that has a high degree of freedom in designing drainage and is easy to maintain.

[Means for Solving the Problems] A drainage device for a passenger conveyor according to the present invention includes a storage member that is installed at the bottom of the passenger conveyor and stores water that has entered the main frame; It consists of an oil-water separator installed in the storage member to separate and remove oil mixed in infiltrated water and discharge the infiltrated water to the outside of the main frame.
