JPH07304584A - Oil pan cleaning device for passenger conveyor - Google Patents

Abstract

PURPOSE:To clean an oil pan in a short time without removing a footstep at all by installing and fixing a cleaning device by using a recess and projection formed on a cleat surface of the footstep to travel on the return side. CONSTITUTION:Operation of an escalator is stopped, and an operator enters an upper machine room 7A, and installs a cleaning device on a cleat surface of a footstep 3 situated in an upper folded part 8A. That is, respective fixed pieces 11A, 12A and 13A are inserted in a recessed part on the cleat surface, and after movable pieces 11B, 12B and 13B are inserted in an adjacent recessed part, machine screws 11C, 12C and 13C are screwed in, and a projecting part on the cleat surface situated between the pieces are sandwiched by the fixed piece 11A and the movable piece 11B, the fixed piece 12A and the movable piece 12B and the fixed piece 13A and the movable piece 13B. Until the footstep 3B moves up to a lower folded part 8B from the upper folded part 8A, dirt and dust accumulated on an oil pan 6 and the other stain are swept off by a sweeping-off member 14, and are gathered to a lower part of the oil pan 6.

Description

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 passenger conveyors.

[0002]

2. Description of the Related Art Conventionally, as a device of this kind, a practically developed device has been used.
As described in Japanese Patent Publication No. 796993, a sheet material is laid on an oil pan, sand and dust falling from the steps are dropped on the sheet material, and the sheet material is wound up in a lower machine room after a predetermined period has elapsed. What was made, and Japanese Patent Publication Sho 58-445
As described in Japanese Patent Publication No. 97, some steps are removed and, instead, a scraping plate is attached, and then the passenger conveyor is operated to collect and remove dust accumulated on the oil pan near the lower machine room. Something is known.

[0003]

However, in the former case, since the sheet material has to be provided on the oil pan, and the space on the oil pan is very narrow (30 mm), the existing passenger conveyor has a new structure. It requires a large amount of work, such as the fact that most of the steps need to be removed before installation.

Even in the latter case, the work of removing the steps is inevitably necessary. Therefore, the cleaning time of the oil pan also becomes long.

It is an object of the present invention to provide an oil pan cleaning device for a passenger conveyor, which is capable of cleaning the oil pan in a short time without removing any steps.

[0006]

[Means for Solving the Problems] The above object is to provide a plurality of steps which are connected endlessly and circulate between two entrances and exits, balustrades installed on both sides of the row of steps, and a return side of the steps. In the oil pan cleaning device of the passenger conveyor, in which the unevenness is alternately formed, the cleat of the step is provided with an oil pan arranged along the dust pan, dust, oil, etc. accumulated or adhered on the oil pan. When cleaning, the oil pan cleaning device attached to the step on the return side has elasticity or flexibility, and a plurality of holding members for fixing the cleaning device to the step by sandwiching the convex part of the cleat surface. This is achieved by adopting a configuration including a wiping member which is made of a material and whose free end side comes into contact with the oil pan.

[0007]

As described above, since the cleaning device is attached and fixed by utilizing the unevenness formed on the cleat surface of the step running on the return side, it is not necessary to remove the step at all.

Further, after the cleaning device is attached and fixed to the step in the upper machine room (upper folding part), the passenger conveyor is operated to move the cleaning device to the lower machine room (lower folding part) to clean the oil pan. At the end, cleaning time is
The time required for mounting and removing the cleaning device and the time required for any step to move from the upper folding portion to the lower folding portion are the total time, and the oil pan cleaning can be performed in a short time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to an escalator will be described below with reference to FIGS.

As shown in FIG. 3, a plurality of escalators are connected to each other, and a step 3 circulates between an upper entrance 1 and a lower entrance 2 and balustrades 4 installed on both sides of the step 3. And a handrail 5 provided along the balustrade 4 and traveling in the same direction as the step 3 at substantially the same speed, and a return side step 3
It is composed of an oil pan (oil receiver) 6 which is arranged at a distance (about 30 mm) from B, an electric motor for traveling the steps 3, a speed reducer (not shown), and the like. 3A
Is a step on the riding side, 7A is an upper machine room, 7B is a lower machine room,
8A shows an upper folded portion of the step 3 and 8B shows a lower folded portion of the step 3. Further, as shown in FIG. 2, a large number of irregularities are alternately and continuously formed on the cleat surface 3C of the step 3.

The cleaning device 9 according to the present invention is shown in FIGS.
As shown in FIG.
Clamping members 11, which are respectively arranged at both ends and the central portion of the
12, 13 and the wiping member 1 attached to the cleaning device body 10.
4 and. The sandwiching members 11, 12, 13 include fixed pieces 11A, 12A, 13A having a thickness slightly smaller than the recess of the cleat surface 3C, movable pieces 11B, 12B, 13B having a thickness slightly smaller than the recess, and the movable piece, respectively. It is composed of screws 11C, 12C and 13C for tightening to the fixed piece. The wiping member 14 has a height such that its tip (free end) comes into contact with the oil pan 6 when the cleaning device 9 is mounted on the step 3B traveling on the return side, and a material having elasticity such as sponge, It is made of a flexible material such as a brush.

When cleaning the oil pan 6, the operation of the escalator is stopped, the upper machine room 7A is entered, and the cleaning device 9 is mounted on the cleat surface 3C of the step 3 located at the upper folding portion 8A. This mounting is done with each fixed piece 11A, 1
2A and 13A are inserted into the recesses of the cleat surface 3C, the movable pieces 11B, 12B and 13B are inserted into the adjacent recesses, and then the screws 11C, 12C and 13C are screwed into the fixed pieces 11A and 1C.
By tightening to 2A and 13A, and sandwiching the convex portion of the cleat surface 3C located between the fixed piece 11A and the movable piece 11B, the fixed piece 12A and the movable piece 12B, and the fixed piece 13A and the movable piece 13B. Done.

Next, the escalator is operated to move the step 3B provided with the cleaning device 9 to the lower folding part 8B and then stop it. While the step 3B moves from the upper folding portion 8A to the lower folding portion 8B, dust and other dirt accumulated on the oil pan 6 is wiped off by the wiping member and collected in the lower portion of the oil pan 6. The cleaning is completed by removing the dust, loosening the screws 11C, 12C, 13C and removing the cleaning device 9 from the step 3B.

In the above embodiment, the cleaning device 9 at the time of cleaning has been described as being mounted on any one step 3B, but it may be mounted on two or more steps 3B. Further, a brush and a sponge may be used together as the wiping member, and the brush may be arranged in the front in the traveling direction and the sponge may be arranged in the rear.

By doing so, it becomes possible to remove dust and cotton dust with a brush and wipe off oil with a sponge.

[0016]

As described above, according to the present invention, the oil pan can be cleaned in a short time without removing any steps.
