DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to steps for a passenger conveyor,
In particular, the present invention relates to a step transport device for a passenger conveyor that transports a heavy step such as a wheelchair step from an entrance / exit to an installation position.

[0002]

2. Description of the Related Art FIG. 4 is a side view for explaining a main structure of a passenger conveyor for a wheelchair.

Generally, as shown in FIG. 4, a wheelchair passenger conveyor has a normal step 1 and, for example, two wheelchair steps 2 connected endlessly and circulating, and a wheelchair step 2. Is provided with a drive device (not shown) for vertically moving the tread surface 2a.

[0004] In the passenger conveyor for wheelchairs configured as described above, the driving device is driven to set the tread surface 2a of the step 2 to the same height position as the tread surface 1a of the step 1 located above, so that these tread surfaces are provided. A relatively wide horizontal surface is formed by 1a and 2a, so that the wheelchair 13 can be mounted.

[0005]

However, in the above-described conventional passenger conveyor for wheelchairs, the steps 2 for wheelchairs are used.
, The normal step 1 is about 25k
g, while the steps 2 for wheelchairs are about 150
It is as heavy as kg. For this reason, when installing the steps 2 for wheelchairs, it is necessary for workers to lift by four or five people and to carry them from the entrance / exit to a predetermined installation position, which requires a large number of workers. In addition, there is a problem in that safety is reduced when a large number of workers carry heavy objects in a place where the scaffold is relatively poor.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-described problems, and has as its object to provide a passenger conveyor step transport device capable of easily transporting a heavy step without requiring a large amount of manpower. It is in.

[0007]

SUMMARY OF THE INVENTION In order to achieve this object, the present invention provides a passenger conveyor provided with a moving handrail which runs along the upper end of a balustrade standing upright on both sides of a step. Step transport device for a passenger conveyor for transporting a vehicle from an entrance / exit to an installation position, a step transport guide rail fitted on each of the moving handrails, and these steps
A wheel that rolls on a transport guide rail, a beam spanned over the respective guide rail and supported by the wheel, and a lift provided on the beam and suspending the predetermined step Means.

[0008]

Since the present invention is constructed as described above, first, the guide rails are fitted on the moving handrails, and the beams are hung on the guide rails so that the wheels come on these guide rails. hand over. Next, a predetermined step is hung by a lifting means provided on the beam body and transported from the entrance / exit to the installation position. As described above, since a predetermined step is transported by the lifting member, a heavy step can be easily transported without requiring much manpower.

[0009]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a passenger conveyor step conveying apparatus according to the present invention. FIG. 1 is a front view showing one embodiment of a passenger conveyor step transport device of the present invention, FIG.
3 is a side view of the step carrier of FIG. 1, and FIG. 3 is a plan view of the step carrier of FIG.

Generally, as shown in FIG. 1, a passenger conveyor, for example, an escalator, includes a balustrade 3 erected on both sides of a step (not shown) and a moving handrail 4 running along the upper end of the balustrade 3. ing.

As shown in FIGS. 1 to 3, the step transport device of the present embodiment has guide rails 5 fitted on a moving handrail 4 and these guide rails 5 respectively.
A wheel 6 rolling on the upper side, a beam 7 spanned on each guide rail 5 and supported by the wheel 6, provided on the beam 7 via a fastening member 8, a predetermined step,
For example, lifting means for suspending the wheelchair steps 9, for example, a chain block 10, a lifting rope 11 connecting the wheelchair steps 9 and the chain block 10, and a lifting means 11 between the lifting rope 11 and the wheelchair steps 9 And a suspending bracket 12 interposed therebetween.

In this embodiment, when the wheelchair step 9 is carried in from the entrance, first, FIGS.
The guide rails 5 are fitted into the horizontal portions of the left and right hand rails 4 as shown in FIG. Next, a demarcation part (not shown) provided on both sides of the wheelchair step 9 carried by a bogie or the like (not shown) so that the wheelchair step 9 can be lifted can be lifted, and a hanging bracket using a screw hole at the mark is removed. 12 is screwed. Thereafter, one end of a lifting rope is attached to the lifting bracket 12, and the chain block 10 is operated to lift the wheelchair step 9 and transport it to a predetermined position. When the vehicle reaches the predetermined position, the wheelchair steps 9 are suspended by the procedure reverse to the above, and a series of transportation operations is completed.

In the embodiment configured as described above, a predetermined step, that is, the step 9 for a wheelchair is transported by the chain block 10, so that a heavy step can be easily transported without requiring a lot of manpower. it can.

[0014]

Since the present invention is constructed as described above, it is possible to easily carry a heavy step without requiring a lot of manpower, thereby efficiently carrying out the step of carrying the step. In addition to this, it is possible to prevent a decrease in safety caused by a large number of workers carrying heavy objects in a place where the footing is relatively poor.
