Abstract

PURPOSE:To enable rain water to be drained out without storing it by providing a hole in the horizontal section of an oil pan at the side of an upper floor, connecting a drain pipe with the hole, and concurrently connecting the end of the pipe with a section connected with an external drain system. CONSTITUTION:An oil pan 10 is made up out of a horizontal section 10a at the side of an upper floor, a slant section 10b and of a horizontal section 10c at the side of a lower floor, and a drain pipe 13 which is inclined in such a way that one in the slant section 10b side is low, is connected between the horizontal section 10a at the upper floor side and the slant section 10b. The drain pipe 13 is connected at its upper end side with a hole 14 provided for the horizontal section 10a at the upper floor side via a pivotally supporting section so that the other end of the drain pipe 13 is penetrated into a hole 16 in the slant section 10b close to the horizontal section. A drain oil pipe 11 is fitted onto the horizontal section 10c at the lower floor side, rain water flowing from the hole 14 into the horizontal section 10a at the upper floor side flows into the slant section 10b and the horizontal section 10c at the lower floor side through the drain pipe 13 so that it flows out of the drain oil pipe 11. This can thereby prevent a driving device, other mechanical sections and the like from failing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an outdoor escalator, and particularly to an improvement of an oil pan.

(Prior Art) As is well known, an escalator has a drive device 2 installed on the upper floor (horizontal part) of a truss 1 as shown in FIG. An annular step chain 6 is wound between the side step sprocket 4 and the driven side step sprocket 5 provided on the lower step (horizontal part) of the truss 1, and connected to this in an endless manner, and the step roller 7a
, 7b guided by a step rail (not shown) is run, and a rubber handrail 8 is run in synchronization with the step 7 to continuously transport passengers.

By the way, the above-mentioned step chain 6, step drive chain 9, and rubber handrail drive chain (not shown) are oiled for lubrication, but as a catch when this oil scatters,
An oil pan 10 extending over the entire length is provided at the bottom of the truss 1. This oil pan IO has an upper floor side horizontal portion 10a corresponding to the shape of the truss 1.

The oil that falls into the oil pan 10 formed from the inclined part 10b and the lower horizontal part 10c is transferred to the upper horizontal part 10.
Flows from a to the horizontal part 10c on the lower floor side via the inclined part 10b,
Oil drain pipe 11 connected to this lower floor side horizontal part 10c
It is designed to be discharged to the outside.

On the other hand, escalators are manufactured with different floor heights, so the floor height changes in stages, and when installed, it is the same as or higher than the floor height of the building and is the closest one. I choose the one with the highest floor height. For this reason, often
The floor height of the escalator is higher than the floor height of the building, and when the escalator is installed in the building, the bottom of the upper floor side horizontal portion of the truss 1 is lower on the support portion 12 side (the right side in the figure).

Therefore, the upper horizontal portion 10a of the oil pan 10 is
It will be tilted toward the support portion 12 side.

When the upper horizontal portion 10a tilts toward the support portion 12 in this way, the oil that has fallen onto the upper horizontal portion 10a accumulates on the support portion 12 and does not flow toward the lower horizontal portion 10c. However, in indoor escalators, this accumulation of oil does not pose much of a problem.

(Problem to be Solved by the Invention) However, in an outdoor escalator installed outside a building, rainwater that has entered the inside of the escalator also collects on the support part 12 side of the horizontal part 10a on the upper floor. The rainwater evaporates due to the heat generated by energizing the drive device 2, creating a humid environment, and the drive device 2 and other mechanical parts are exposed to a high temperature and humidity atmosphere for a long period of time. This may cause a decrease in the reliability and safety of these devices due to deterioration of insulation performance, corrosion, etc.
This improvement was desired.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide oil for outdoor escalators that prevents rainwater, etc. that has entered the horizontal part of the upper floor of the oil pan from accumulating, thereby preventing malfunctions in the drive device and other mechanical parts. It provides bread.

[Structure of the invention]

(Means for Solving the Problems) The present invention provides an oil pan for an outdoor escalator that is provided over the entire length at the lower part of the truss and consists of an upper floor side horizontal part, an inclined part, and a lower floor side horizontal part. A hole is provided in the side horizontal portion, and a drainage member is provided with one end connected to the hole and the other end connected to a portion connected to an external drainage system.

(Function) The escalator is installed so that the horizontal part on the upper floor is tilted toward the end, so even if rainwater enters the escalator, it will be discharged to the outside through the drainage pipe, so it will not accumulate, and rainwater will be generated from the drive device, etc. It is possible to prevent problems such as evaporation due to the heat generated, resulting in a decrease in insulation performance or corrosion.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.
