Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a passenger conveyor, and more particularly to an improvement in a cleaning device suitable for cleaning an oil receiving portion in a truss of a passenger conveyor with a large installation angle.

A lot of dust accumulates in the oil pan inside the truss of the passenger conveyor depending on the users and the installation environment, which can cause fires due to lingering cigarettes.

Conventionally, as a device for cleaning these dust, there is a cleaning device for horizontal parts such as moving walkways or gentle passenger conveyors with an angle of inclination of 10 degrees or less, but this device can only clean the treads and oil pans in the truss. The depth in the department covers the entire process,
The inclination angle 1 is limited to applications that are limited to uniform structures, and the overwhelming majority of units are installed as vertical transportation systems in buildings and stations.
It has the disadvantage that it cannot be used to clean escalators whose temperature exceeds 0 degrees.

That is, the depth at which the return tread and the oil pan in the truss face each other differs depending on the horizontal section, the curved wide/deep section, and the inclined straight section, and also differs depending on the installed model.

Therefore, with conventional brush-type cleaning devices that are fixed to the treadle for a certain length, the brush cannot follow the depth of the oil receiver, which differs from part to part, and it is not possible to obtain a sufficient cleaning effect. This caused the inconvenience of not being able to collect the dust.

The present invention eliminates the drawbacks of the conventional ones mentioned above,
To provide a cleaning device for a passenger conveyor that can effectively remove dust from an oil receiving part of a passenger conveyor such as an escalator with a large inclination angle.

The gist of the present invention is to arrange a large number of treadboards, each attached to a front wheel axle and a rear wheel axle, in an endless manner, and to arrange the treadboards at different depths from the locus of the front wheel axle at the bottom of the turning side of the treadboards. A rubber plate is provided on the oil receiving part side between the front wheel axle and the oil receiving part, and a lower end is attached to the upper end of this rubber plate. The first arm is connected to the first arm and extends diagonally upward at the middle part and is bent, the lower end of which is adjustably connected to the upper end of the first arm through a long hole in the longitudinal direction, and the first arm is bent at the middle part and the upper end part is connected to the first arm. is provided with a cleaning tool consisting of a curved part that fits onto the front wheel axle and a second arm that has a presser metal fitting that presses the curved part from above when the curved part is fitted onto the front wheel axle, and this cleaning tool is attached to the front wheel axle as described above. The rubber plates are connected to each other so as to be swingable through a curved portion, and the rubber plate is moved while being in contact with the oil receiving portion to clean the oil receiving portion.

The present invention will be explained below with reference to embodiments shown in the drawings.

Referring to FIG. 1 and FIG. 2, the cleaning member is constituted by:
A pair of front and back reinforcing plates 2, 2 are stretched horizontally on the upper end of the rubber plate 1, which has sufficient elasticity. 1 arms 4, 4 are attached.

Each first arm 4 extends above the rubber plate 1 and is bent diagonally upward at the middle portion.

A long hole 5 in the longitudinal direction is formed in the upper end of the first arm 4, and an adjustment screw 7 attached to the tip of the second arm 6 is screwed into the long hole 5.

By changing the fixing position of the adjustment screw 7 in the elongated hole 5, the distance from the base end of the second arm 6 to the tip 1 of the rubber plate 1 can be adjusted according to the depth of the escalator truss to be cleaned. Can be adjusted.

FIG. 3 shows the lengthened condition resulting from this adjustment.

The second arm 7 is also bent and buttoned at the middle part, and the base end of the second arm 7 is formed with a curved part 10 into which a front wheel shaft 9 of a footboard 8, which will be described later, is fitted. A presser metal fitting 11 can be pressed into contact with the mounting screw 12 by means of a mounting screw 12.

The operation of the above-described embodiment will now be explained with reference to FIGS. 4p and 5.

FIG. 4 shows a side view of the escalator, and the locus 13 of the front wheel axis 9 of the turning tread 8 is the same as the rear wheel axis 1 of the turning tread 8.
It is located below the locus 15 of No. 4.

An oil receiver 17 in the truss 16 below the front wheel axle 9
has a horizontal part 18, a curved wide and deep part 19, and an inclined straight part 20.
The depths from the locus 13 of are a t b and C, respectively.
(1) > C > a).

To clean the oil receiver 17 described above with the cleaning tool,
Draw any two treads 8 in the upper machine room of the escalator.
, 8 and, of the two exposed front wheel axles 9, 9, if the cleaning tool is pivotally attached to the front wheel axle 9 of the footboard 8 closest to the driving direction as shown in Fig. 5, the rubber plate 1 comes into contact with the oil receiving portion 17 while creating an angle suitable for wiping away dust.

Therefore, if the treadle 8 is operated in the direction of the arrow, as shown in FIG.
It swings around the front wheel shaft 9, forms an angle α, presses onto the oil receiver 17, and wipes away dust.

B) In the curved wide and deep portion 19, the rubber plate 1 swings again, and the tip angle of the rubber plate 1 is displaced to α2 to wipe away dust.

C) In the inclined straight portion 20, the rubber plate 1 further swings, and the tip angle of the rubber plate 1 is displaced to α3 to wipe away dust.

If the above operation is performed continuously throughout the entire stroke of the oil receiving portion 17, the dust can be swept toward the lower truss 16 and cleaned.

After cleaning is completed, the cleaning tool is removed in the lower machine room, and the removed treadle 8 is attached to the front wheel axle 9 in the upper machine room to complete the work.

This cleaning tool is not used during normal operation.

As mentioned above, in the passenger conveyor cleaning device according to the present invention, since the length-variable cleaning tool is swingably pivoted to the rotating shaft of the tread, it is possible to clean the inside of the truss on an escalator with a large inclination angle. Dust on the oil pan can be thoroughly cleaned from the return treadle.

Even long, broken conveyors can be cleaned easily and efficiently, and the risk of fire caused by dust can be prevented.
