Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a cleaner for a passenger conveyor guide rail.

[Background of the invention]

As shown in Figure 1, the passenger conveyor is
and a step 2 connected by a step chain 7 in an endless manner, and each step 2 has a pair of front wheels 3 and a rear wheel 4, and these front and rear wheels 3.4 are As shown in Figure 2, the wheels roll on a front wheel guide rail 5 and a rear wheel guide rail 6, which are respectively installed within the frame of the passenger conveyor.

In a passenger conveyor with such a configuration, if garbage 8 is attached to the footwear of a user, it falls onto the steps 2 as shown in FIG.
- falls onto the wheels 5 and 6 and accumulates. This accumulated dirt 8 becomes an oily and highly sticky substance due to penetration of lubricating oil supplied to the chain or the like. If the guide rail 5.6 is soiled by this sticky debris 8, the smooth transfer of the front and rear wheels 3, 4 on the surface of the guide rail 5.6 will be hindered, causing vibrations that may cause discomfort to passengers. Not only is this a stupid thing to do, but it can also cause a decline in the functionality of the passenger conveyor.

Therefore, it is necessary to clean the surfaces of the guide rails 5 and 6 at appropriate intervals to prevent such problems from occurring.

However, in the conventional cleaning work, a worker takes five to six pieces of the steps 2, enters the conveyor, and wipes them with a cloth or the like. Since such work is carried out in a narrow space, it is inefficient and requires a great deal of labor, and if the man conveyor were to be driven during the work, it would result in a serious accident that could threaten the lives of the workers.

[Purpose of the invention]

An object of the present invention is to provide a cleaning device that can clean guide rails with improved safety and work efficiency.

[Summary of the invention]

The present invention focuses on a step chain that is driven close to the guide rail, and is characterized in that a cleaning tool for cleaning the guide rail is attached to the step chain so that the cleaning work is performed while the passenger conveyor is operating. shall be.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 4 is a perspective view of the cleaner, showing a cleaning tool 9 disposed on the front wheel guide rail 5, a shaft 10 rotatably supporting the cleaning tool 9, and a fixed jig connected to the cleaning tool 9 by the shaft 10. The fixing jig 11 is attached to the step chain 7 by a screw lla.

FIG. 5 shows a specific configuration of the cleaning tool 9 shown in FIG. 4. The cleaning tool 9 has a plurality of sliding pieces 12, each of which is connected by a support member 13, and each sliding piece 12 is made of a bendable elastic body.

FIG. 6 shows the cleaning device shown in FIG. 4 installed on the passenger conveyor, and the cleaning device fixing jig 11 is fitted onto the step chain 7 as shown in FIG. 7 which is an enlarged view. It is firmly attached by screws 11a.

At this time, the cleaning tool 9 is located on the front wheel guide rail 5. When the passenger conveyor is operated in this state, the sliding piece 12 of the cleaning tool 9 slides on the front wheel guide rail 5, and the front wheel guide Debris 8 on the rail 5 can be removed from the turning section. Moreover, since it is sufficient to simply operate the operator conveyor after installing the cleaning device, work efficiency is increased, and safety can be ensured while reducing the labor of the operator.

FIG. 8 shows a cleaning tool 8 according to another embodiment, in which a rectangular groove 14 is provided in each sliding piece 12 other than the last sliding piece in the advancing direction of the step chain 7. This groove 14 may be V-shaped or U-shaped.

FIG. 9 shows another embodiment of the cleaning device fixing jig 11, which has an opposing gap into which the step chain 7 can be inserted, and a claw 11b is formed in this opposing part, and the claw 11b and the screw lla The fixing jig 11 can also be fixed to the step chain 7 by.

In the above embodiment, the front wheel guide rail 5 where dirt easily accumulates is
A cleaning device for cleaning the rear wheel guide rail 6 has been described above, but if dirt accumulates on the rear wheel guide rail 6, a cleaning device fixed to the step chain 7 can be used as in the above case, but the rear wheel guide rail 6 However, since the front wheel guide rail 5 is poorly cleaned, at least the front wheel guide rail 5 is cleaned using a cleaner, and the rear wheel guide rail 6 may be cleaned by another cleaning means.

〔Effect of the invention〕

As explained above, the present invention has a cleaning device fixed to a step chain, and the cleaning tool of the cleaning device is rubbed on the front single wheel guide rail by the operation of a passenger conveyor to remove dirt. The safety of workers can be ensured by eliminating cramped work situations such as Additionally, since cleaning is performed by operating the man conveyor, work efficiency can be increased.
