JPH09227064A - Cleaning device for man-conveyer - Google Patents

Abstract

PROBLEM TO BE SOLVED: To conduct cleaning work without remaining dust, in a man-conveyer provided with an oil pan so as to cover the lower part of a step, by forming a cleaning plate for an oil pan cleaning tool mounted on a front wheel shaft into an inverted L shape to the traveling direction of the step, and providing inclined parts for both ends of it. SOLUTION: Two-or three of steps 8 connected through a front wheel shaft 7 are removed at an arbitrary position, and a cleaning plate 5 is attached. A man-conveyer is then operated at a low speed so as to remove dust on an oil pan 10. At this time, the cleaning plate 5 is fixed near both the ends of the front wheel shaft 7 with fixing hardware 3 and is pressed against the oil pan 10 for covering dust or the like. The cleaning plate 5 is formed into an inverted L shape to the traveling direction of the step 8, fitted at an angle of 90 deg.<α deg. to the oil pan 10 and 90 deg.>β deg. to the contact surface 5b of the oil pan. A bent part 5c is formed respectively at both the ends of the cleaning plate 5, an inclined plate 5a with an inclined angle of γ is formed in its middle, and a dust storage 6 is fitted behind the cleaning plate 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for a man conveyor, and more particularly to a cleaning device for a man conveyor which is suitable for cleaning an oil pan.

[0002]

2. Description of the Related Art A conventional oil pan cleaning device is disclosed in JP-A-56
As described in JP-A-3274, by removing arbitrary 2 to 3 steps of the man conveyor, by attaching a cleaning device to the rear with respect to the moving direction of the front wheel shaft, and operating the man conveyor at a low speed, It was configured to clean the dust on the oil pan.

[0003]

However, in the above-mentioned prior art, since the oil pan is inclined at the upper and lower parts, no gap can be formed on the contact surface between the cleaning plate and the oil pan when passing through this inclination (cleaning plate). The contact surface of the oil pan and the contact surface of the oil pan contact each other at a line perpendicular to the traveling direction). Therefore, when dust is accumulated on the front surface of the cleaning plate and the amount thereof is increased, the dust escapes from both ends of the cleaning plate and remains on the oil pan.

It is an object of the present invention to provide a cleaning device for a man conveyor which prevents dust from escaping from both ends of the cleaning plate and has a high cleaning efficiency.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a plurality of steps which are connected endlessly by a step chain and move, a front wheel shaft which supports and drives the steps, and Provided on the man conveyer having an oil pan provided so as to cover the lower part,
In a cleaning device of a man conveyer for cleaning an oil pan by attaching a cleaning tool to the front wheel shaft, a cleaning plate of the cleaning tool is formed in an inverted L shape with respect to a moving direction of the step, and inclined portions are provided at both ends. It has a different configuration.

According to the present invention configured as described above, when dust is accumulated on the cleaning plate, the dust is brought to the center side of the cleaning plate due to the inclination of both ends of the cleaning plate.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to FIGS.

Here, FIG. 1 is a plan view of the cleaning device, FIG. 2 is a sectional view taken along the line II of FIG. 1, FIG. 3 is a sectional view taken along the line II-II of FIG.
FIG. 4 is a side view of the passenger conveyor. In FIG. 4, two to three steps 8 which are endlessly connected via a front wheel shaft 7 by a step chain 9 are removed from the front wheel shaft 7 at an arbitrary position, and are divided into two parts (3a, 3b) between the front wheel shafts 7. ), The load support 2 is fixed to the load support 2 with bolts 2a, and the load 1 divided into a plurality of parts is fixed to the load support 2 and the load 1 with the bolt 1a. Further, the cleaning plate 5 is fixed to the front wheel shaft 7 near both ends of the front wheel shaft 7 by the fixing members 3 via the arm 4, and the oil pan 1 for covering the oil, dust and the like flowing down from the step 8 and the step chain 9.
Press 0. In FIG. 2, the cleaning plate 5 is formed in an inverted L shape with respect to the moving direction of the step, is attached at an angle of 90 ° <α ° to the oil pan 10, and is 90 °> β ° with the oil pan contact surface 5b. And A curved portion 5c is formed at both ends of the cleaning plate 5 so as to prevent dust from escaping, and an inclined plate 5a having an inclination angle γ is provided so that the dust 11 is located at the center. Further, the cleaning plate 5 is provided with a dust reservoir 6 so that the dust 11 is retained. Guide rollers 7a are attached to both ends of the front wheel shaft 7.

At the time of cleaning, the man conveyor is operated at a low speed from the upper part to the lower part to collect the dust accumulated in the oil pan.

With this configuration, the contact surface with the oil pan becomes a straight line, no gap is formed when passing through the inclined portion of the oil pan, and dust 11 accumulated on the front surface of the oil pan is inclined with respect to the cleaning plate. Since the plate 5a is moved to the center and enters the dust reservoir 6, the amount of escape from both ends of the cleaning plate is reduced, and the cleaning efficiency is improved.

[0011]

With this structure, since the dust accumulated on the front portion of the cleaning plate does not escape from both ends of the cleaning plate, the dust can be cleaned without remaining.
