Abstract

PURPOSE:To improve operation rate, and to realize easy maintenance through efficiently collecting dust falled down into a machine chamber by providing a dust collector having a dust receiver, which masks a foot step or a turning- over outer periphery of a pallet and is demountable downwards. CONSTITUTION:A part of dust 11, which has been thrown away while a foot step 2 is turning over in a machine chamber 4, falls directly into a receiving box 15. On the other hand, the other part of the dust 11, which has been thrown away downwards and slantwise, collides with a vertical portion and a bent portion of a cover body 14 and then falls into the receiving box 15 sliding along these covers. As the result, all of the dust 11 is received inside a receiver 16 of the receiving box 15. Then, if the receiving box 15 is pulled upwards slantwise by gripping knobs 17, the receiving box 15 can be easily demounted from the cover body 14. When the receiving box 15 is demounted outside, the dust 11 contained in it can be easily thrown away to a required location. After that, the empty receiving box 15 is set again into the cover body 14 in reverse order. This operation is performed either regularly or arbitrarily.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to an escalator or a moving walkway, and more particularly to a dust collection device for containing dust falling into a machine room and facilitating its discharge. It is something.

(Prior Art) FIG. 7 is a side view showing an example of the overall configuration of an escalator. As shown in the figure, the escalator has steps 2 mounted on a pair of left and right step chains 1 connected in an endless manner to a machine room 4 on the upper side of a frame (for example, a truss) 3.
It is driven by being wrapped around a driving wheel 5 provided in the lower part of the frame 3 and a driven wheel 7 provided in a machine room 6 below the frame 3. The drive wheel 5 is
It is driven via a chain 9 from a drive device 8 that is installed in the machine room 4 and includes a motor, a speed reduction mechanism, and the like. Furthermore, code 1

(Problem to be Solved by the Invention) However, on the steps 2, there is a lot of dirt, etc. (hereinafter referred to as debris) that was attached to the shoes of the passengers during the transportation of the passengers, as shown by reference numeral 11 in FIG. Fall.

On the outbound side, it is on top of Step 2. This waste 11 is thrown out when the steps 2 are reversed in the machine rooms 4, 6, and is scattered in the machine room 4, 6. As a result, the following problems occurred.

- There is a large possibility that the waste 11 will enter the equipment in the machine rooms 4 and 6, causing malfunction of the equipment and shortening its life.

■ If a cigarette butt discarded by a passenger gets into the area where trash 11 is accumulated, there is a high probability that a fire will break out.

■ It is unsanitary and not good for the health of escalator maintenance personnel.

(a) When the waste 11 accumulates, it must be cleaned regularly, which requires additional maintenance time. However, in recent years, the operating time of escalators has tended to increase, and as a result, maintenance time has been required to be shortened, and an increase in maintenance time cannot meet this demand.

(c) The work of removing waste 11 is a work that is generally disliked, so we have no choice but to pay high labor costs for this work.
This results in increased maintenance costs.

Incidentally, the above explanation was about escalators.

Similar problems occur with moving walkways.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to efficiently collect waste that falls into a machine room, to facilitate maintenance, and to improve operating efficiency. The purpose is to provide an escalator or moving walkway.

[Structure of the invention]

(Means for Solving the Problems) The present invention provides a drive wheel in a machine room at one end of a frame, and a driven wheel in a machine room at the other end, and wraps around the drive wheel and the driven wheel. In an escalator or a moving walkway in which steps or pallets are moved via an endless chain, the machine room covers the inverted outer circumferential side of the steps or pallets, and is capable of storing dust in a removable manner at the bottom. It is equipped with a dust collector having a section.

(Function) Dust that has fallen on the steps or pallets is thrown out by the reversing movement of the steps or pallets in the machine room, hits the dust collector that covers the outer circumference of the inverter, and falls downwards, collecting the dust below the dust collector. It accumulates in the department. Therefore, dust will not be scattered in the machine room, and will not invade the equipment and make its operation unsmooth or shorten its life. In addition, the dust-filled storage area can be easily removed to the outside.
Dust can be thrown away at a predetermined location, making it easy to dispose of dust and making maintenance work easier and shorter.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a side view showing essential parts of an embodiment of the present invention;
FIG. 2 is a perspective view of a dust collector used in one embodiment of the present invention.

In Figures 1 and 2, 1 is the step chain, 2 is the step, 3 is the frame, 4 is the machine room, 5 is the drive wheel, and 12 is the upper end of the frame 3, located close to the inverted part of the step 2. A support plate that is attached to the
A dust collector 13 is detachably attached to this support plate 12. This dust collector 13 includes a cover main body 14 that is attached by hooking the upper part to the U-shaped bent part of the support plate 12;
It consists of a storage box 15 that is attached by hooking the upper part to the lower U-shaped part of the cover main body 14. Install it in a position that will not cause any obstruction. Further, the cover body 14 and the storage box 15 are made wider than the steps 2.

The width is set so as not to hinder the movement of the chain 9 that drives the drive wheel 5.

As shown in FIGS. 3 and 4, the cover main body 14 has an inverted U-shaped upper part that can be hooked onto the U-shaped bent portion of the support plate 12. A bent part 14a is provided at the bottom, and a bent part 14b that is approximately U-shaped with the opening side slightly wider and slopes downward on the same side as the bent part +4a is provided. In addition, in the vertical part 14c,

As shown in FIG. 1, some of the waste 11 falls directly into the storage box 15, but the waste 11 that is thrown diagonally downward hits the vertical part or the bent part 14b of the cover body 14, and is guided by these and stored. All of the waste 11 falls into the box 15 and is stored in the storage section 16 of the storage box 15.

Therefore, by grasping the handle 17 and lifting it diagonally upward, the storage box 15 can be easily removed from the cover body 14, and by taking out the removed storage box 15 to the outside, the stored waste 11 can be easily placed in a predetermined place. You can throw it away. The storage box 15 in which the waste 11 has been discarded is set on the cover body 14 again in the reverse order. This work may be performed regularly or at any time.

Although the upper machine room 4 has been described above, a dust collector having a similar configuration is also attached to the lower machine room 6. However, in this case, the mounting state will be symmetrical. Further, although the above description has been made regarding escalators, the same method can be applied to moving walkways.

However, in this case, the steps become pallets, and the upper,
The lower machine room serves as the machine room at both ends.

Therefore, with the above configuration, when the steps are turned over in the machine room, the waste that falls from the steps is stored in the storage box without scattering, and the storage box can be easily removed from the cover body and taken outside. can be disposed of in a designated place. Furthermore, the storage box after the waste has been discarded can be easily set back to its original state.
