Description

TECHNICAL FIELD The present invention relates to a cleaning tool for cleaning the inner peripheral surface of a moving handrail for a passenger conveyor.

An escalator as a passenger conveyor is provided with balustrades on both sides of a stepped tread that automatically ascends and descends, and a moving handrail that moves in the running direction of the escalator is provided above the balustrade. The moving handrail is formed in an endless shape in the moving direction, and has a substantially C-shaped cross section when viewed from the moving direction (including a flat portion in the center and curved portions formed to face each other on both sides of the flat portion). is.

The moving handrail is guided by the handrail guide rail, and the flat portion is sandwiched between the handrail driving roller and the pressure roller, and is driven in the moving direction by friction. The handrail drive roller is rotated via a chain or the like from the drive source of the footboard.

Abrasion powder of the moving handrail and the handrail guide rail due to friction between the moving handrail and the handrail guide rail, dust inside the truss, and the like adhere to the inner peripheral surface of the moving handrail. As a result, the frictional force between the flat portion of the moving handrail and the handrail drive roller is reduced, and slip occurs between them. As a result, the footboards and the moving handrails are out of alignment with each other, resulting in poor riding comfort for the passengers. In addition, foreign matter adhering to the inner surface of the moving handrail may drop onto the treads and stain the clothes of the passengers.

In order to avoid the above situation, it is necessary to periodically clean the inner peripheral surface of the moving handrail. For example, Patent Literature 1 discloses a cleaning tool for cleaning the inner peripheral surface of a moving handrail. The cleaning tool disclosed in Patent Document 1 cleans the flat portion and the curved portion of the inner peripheral surface of the moving handrail with independent rotating brushes, respectively, and sucks dust with a suction device.

An example of an embodiment of the present invention will be described in detail below. In the following description, specific shapes, materials, directions, numerical values, etc. are examples for facilitating understanding of the present invention, and can be appropriately changed according to usage, purpose, specifications, and the like.

A moving handrail 92 provided on an escalator 90 according to an embodiment will be described with reference to FIGS. 1, 2A, and 2B.

The escalator 90 includes a plurality of steps (not shown) that ascend or descend along an inclination, balustrades 91 provided on both sides of the steps, and moving handrails 92 that move in synchronization with the steps. A handrail guide rail 93 that guides the circular movement of the moving handrail 92 is provided on the outer periphery of the balustrade 91 (see FIG. 2A). The handrail guide rail 93 forms a circulation path for guiding the circular movement of the moving handrail 92 .

The moving handrail 92 is made of rubber and has an endless shape, and its cross-sectional view (cross-sectional view in the width direction) when viewed in the moving direction is substantially C-shaped (a flat portion 92A in the center and a flat portion 92A facing each other on both sides). (including the curved portion 92B formed by doing so). The moving handrail 92 is supported by a handrail guide rail 93 so as to be circulatingly movable. A handrail driving roller 94 , a pressure roller 95 and a handrail tensioning device 96 are arranged on the circulation path of the moving handrail 92 .

The handrail driving rollers 94 are driving wheels for driving the moving handrail 92 . A moving handrail 92 is wound around part of the outer periphery of the handrail driving roller 94 . A pressure roller 95 is arranged so as to sandwich the moving handrail 92 wound around the handrail driving roller 94 . The pressure roller 95 presses the moving handrail 92 against the handrail driving roller 94 . The moving handrail 92 moves synchronously with the steps by the rotation of the handrail drive roller 94 .

A moving handrail 92 is wound around part of the outer circumference of the handrail tensioning device 96 . The tension applied to the moving handrail 92 is adjusted by moving the handrail tensioning device 96 outwardly or inwardly with respect to the circulation path.

Next, the operation when the moving handrail 92 circulates will be described. The moving handrail 92 is given a predetermined tension necessary for stable circular movement by a handrail tensioning device 96 . When the handrail driving roller 94 rotates, the driving force is efficiently transmitted to the moving handrail 92 pressed against the pressure roller 95 . As a result, the moving handrail 92 can circulate through the circulation path.

At this time, the moving handrail 92 circulates while contacting the handrail guide rail 93, the handrail drive roller 94, the handrail tension device 96, and the like. As a result, the rubber on the canvas surface, which is the contact surface of the moving handrail 92, is worn away, and abrasion powder is generated from the canvas surface. In addition, dust and the like adhere to the truss.

As a result, the frictional force between the flat portion 92A of the moving handrail 92 and the handrail driving roller 94 is reduced, and a slip occurs between the moving handrail 92 and the handrail driving roller 94. As a result, the movement of the moving handrail 92 and the treadboards is deviated, resulting in poor riding comfort for the passengers. In addition, foreign matter adhering to the inner surface of the moving handrail 92 may drop toward the treads and stain the clothes of the passengers.

In order to avoid the situation described above, it is necessary to periodically clean the inner peripheral surface of the moving handrail 92 . The cleaning tool 10 for cleaning the inner peripheral surface of the moving handrail 92 of the escalator 90 will be described below.
