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 footboard such as a moving sidewalk or an escalator, and more particularly to a cleaning device for automatically cleaning a groove of a moving footboard.

[0002]

2. Description of the Related Art As a conventional example relating to a cleaning device for a movable tread, there is known an escalator type passenger conveyor disclosed in Japanese Utility Model Application Laid-Open No. 58-187568.

[0003]

In the above prior art, a cleaning brush or felt slidably contacting the groove of the moving tread plate is directly planted on the tooth tip of the comb plate.
There is a fundamental defect that when the tooth tip is lost, the cleaning function is completely lost. The problem is that if a foreign object such as pebbles enters the moving tread and a strong external force is generated between the teeth and the groove of the comb plate, the tooth is damaged first and the groove is protected. Since the comb plate is treated as a consumable item in accordance with the design concept of performing the cleaning, the disappearance of the cleaning function frequently occurs on a daily basis. Further, in the configuration of the above-described conventional example, since the external force of the pebbles or the like acting on the cleaning brush or the like is directly transmitted to the tooth tip, there is also a problem that the comb plate is damaged due to this.

[0004] It is an object of the present invention to provide a cleaning device for a movable tread plate having a configuration that is excellent in life and maintainability.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a tread plate which is connected endlessly from one getting on and off floor to the other getting on and off and has a large number of grooves on its tread surface. In a device provided with a base fixed to the tip of the getting on and off floor and a comb plate having a number of tooth tips meshing with the concave grooves, the tip of the getting on and off floor is vertically sandwiched between the getting on and off floor and the base. A fixed plate having a width equal to the width of the comb plate, a sliding contact brush positioned at the tip of the fixed plate and abutting in the concave groove, A cleaning device consisting of a connecting body for connecting the contact brush was provided. According to the configuration of the cleaning device, the sliding contact brush that comes into contact with the concave groove of the movable tread plate is separate from the comb plate, and the conventional problem (tooth tip loss) is solved. Since the width of the brush is equal to the width of the comb plate, it is possible to easily cope with the inspection of the sliding contact brush and the wearing life by detaching and removing one comb plate located above the sliding brush, thereby greatly improving the maintainability. be able to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 3 using an escalator-type passenger conveyor as an example. In FIG. 1 which shows a perspective view of the vicinity of one entrance of the passenger conveyor 1, the passenger conveyor 1 is connected endlessly from one floor 2 to the other floor (not shown), and its tread surface 3A. And a comb plate 4 having a number of tooth tips 4B that mesh with the roots 4A and the grooves 3B that are fixed to the tip 2A of the floor 2 and that move. ing. Here, the comb plate 4 corresponds to FIG.
As shown in FIG. 2 which is a cross-sectional view taken along line II of FIG. 2, a root portion 4A fixed to a flat slope 2B of a tip end portion 2A of the getting on / off floor 2 with screws 5 and a number of uneven teeth connected to the root portion 4A It has a tip 4B, which has a width W of 100 mm as shown in FIG.
Plural pieces of the board 2 and footboard 3 are continuously arranged in the width of the board 2 and the footboard 3 in such a manner as to be divided. Furthermore, the flat slope 2B
A cleaning device 6 having a cross-section shown in FIG. 2 and a single-unit external width Wa shown in FIG. 3 is fixedly provided between the base unit 4A and the base unit 4A in the vertical direction. The cleaning device 6 has a width Wa that is equal to or slightly smaller than the width W of the comb plate 4 (m in FIG. 3), and includes a fixed plate 6A made of a flat metal material or a synthetic resin material. The fixed plate 6A is located at the tip of the fixed plate 6A, and is formed of a combination with a connecting body 6C for connecting a sliding brush 6B to be brought into contact with the concave groove 3B. Then, when foreign matter Q such as pebbles that has entered between the concave groove 3B of the tread plate 3 and the tooth tip 4B that moves as shown by the arrow M in FIG. 2 wears the bristle tip of the sliding brush 6B with time, There is no breakage of the comb plate as in the prior art, and the screw 5 is removed from the hole 6D of the comb plate 4 and the fixing plate 6A. The maintenance can be greatly improved as compared with, for example, a method in which a sliding contact brush is provided on the return movement of the tread plate 3.

The cleaning device 6 is not limited to the illustrated shape of the moving tread 3 but may be applied to a flat plate or a rubber belt having a concave groove.

As described above, according to the present invention, it is possible to provide a cleaning device for a moving tread plate having excellent life and maintainability.
