DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for centering a passenger conveyor which determines the arrangement of equipment constituting a movable structure with reference to the position of a down swing installed at the center in the width direction of the passenger conveyor.

[0002]

2. Description of the Related Art Conventionally, in a passenger conveyor, for example, an escalator, a bobbin is installed at the center in the width direction of the escalator, and based on the position of the bobbin, a passenger conveyor that determines the arrangement of the equipment constituting the movable structure. Is applied.

[0003] The movable structure of the escalator is, for example, a handrail drive mechanism for driving a handrail. The handrail drive mechanism includes a plurality of gears, a chain looped between the gears, a plurality of drive rollers and driven rollers for nipping and driving the handrail, and a plurality of support rollers for supporting the handrail. And a holder attached to the frame and holding each gear and each roller.

[0004] In the work of installing the handrail drive mechanism, the above-described centering method is applied, and thereby the arrangement of the gears and rollers is determined.

For example, the arrangement of the gears is determined by performing the following (1) to (5).

(1) A swing is installed.

That is, a pillar is provided on each of the floor frame of the landing on the upper floor and the floor frame of the landing on the lower floor. .

(2) The gears are attached to the holder to make the equipment and the holder into an assembly.

(3) This assembly is arranged at a predetermined position in the longitudinal direction of the frame.

(4) The distance between the gear and the vertical plane on which the bobbin moves is measured.

That is, the down swing is slid along the piano wire and fixed at a position corresponding to the longitudinal position of the gear. Then, the down swing and the distance between the gears are measured.

(5) The horizontal position of the entire assembly is adjusted by using an adjustment liner or the like so that the distance between the gear and the bobbin coincides with a predetermined dimension, whereby the horizontal position of the gear is adjusted. To adjust.

As described above, for each gear and each roller, using the down swing set in (1), (2) to (5)
To determine each arrangement.

[0014]

However, some gears and rollers have a step or unevenness in a portion facing the down-plummet. Therefore, when measuring the down-pulse and the distance between the gears, a tape measure or the like is required. It is difficult to arrange the measuring instruments properly, and a measurement error may occur.

[0015] If a measurement error occurs, the centering accuracy of the gears and the rollers deteriorates. That is, regarding the gears, since the positions between the gears do not correspond to each other, the chain and the gear do not mesh properly, and the gear and the chain are not driven smoothly. For this reason, there has been a problem that an improper load is applied to the chain and the gear, abnormal wear occurs, and the life of the gear and the chain is shortened.

[0016] Similarly, since the positions of the rollers do not correspond to each other, there is a problem that an improper load is applied to the handrail and the life of the handrail is shortened.

An object of the present invention has been made in consideration of the above-mentioned problems, and provides a method of centering a passenger conveyor capable of improving the centering accuracy of equipment constituting a movable structure of the passenger conveyor. It is in.

[0018]

As a means for achieving the above object, a method for centering a passenger conveyor according to the present invention is based on a position of a plunger installed at the center of the passenger conveyor in the width direction. In the centering method of the passenger conveyor to determine the horizontal arrangement of the equipment constituting the movable structure,
When the holding body attached to the frame of the passenger conveyor and holding the equipment is to hold the equipment with a flat plate portion facing the plunger, adjusting the horizontal position of the equipment, By performing by adjusting the horizontal position of the plate portion with respect to the down swing, when adjusting the horizontal position of the plate portion, determine a measurement surface on the plate portion, the plate portion and The method is characterized in that a distance between the down swings is measured, and a position of the plate portion is adjusted so that the distance matches a predetermined dimension.

In this method, by adjusting the position of the plate portion so that the distance between the plate portion of the holding body and the downswing coincides with a predetermined dimension, the position of the equipment with respect to the downswing is adjusted.

At this time, since the measurement surface is defined on the flat plate portion, it is easy to arrange a measuring instrument such as a tape measure, and it is easy to measure the distance between the plate portion of the holder and the bobbin.

As a result, the occurrence of a measurement error can be prevented,
The centering accuracy of the equipment constituting the movable structure can be improved.

In the above-described method for centering the passenger conveyor, the following (1) to (6) may be adopted.

(1) The measurement surface is a smooth exposed surface obtained by removing the paint applied to the plate portion during the manufacturing process.

(2) The measurement surface is a smooth exposed surface which is not coated on the plate portion during the manufacturing process.

(3) In the case of (1) or (2), after attaching the holder, rust is applied to the exposed surface.

(4) The measurement surface is a smooth surface formed by attaching a plate.

(5) The movable structure is a drive mechanism for driving a handrail of the passenger conveyor, and the equipment is a gear and a roller which are components of the drive mechanism.
